Abstract
Inflammatory cascades of the dysregulated inflammatory pathways in COVID-19 can cause excessive production of pro-inflammatory cytokines and chemokines leading to cytokine storm syndrome (CSS). The molecular cascades involved in the pathways may be targeted for discovery of new anti-inflammatory agents. Many plant extracts have been used clinically in the management of COVID-19, however, their immunosuppressive activities were mainly investigated based on in silico activity. Dietary flavonoids of the extracts such as quercetin, luteolin, kaempferol, naringenin, isorhamnetin, baicalein, wogonin, and rutin were commonly identified as responsible for their inhibitory effects. The present review critically analyzes the anti-inflammatory effects and mechanisms of phytochemicals, including dietary compounds against cytokine storm (CS) and hyperinflammation via inhibition of the altered inflammatory pathways triggered by SARS-CoV-2, published since the emergence of COVID-19 in December 2019. Only a few phytochemicals, mainly dietary compounds such as nanocurcumin, melatonin, quercetin, 6-shagoal, kaempferol, resveratrol, andrographolide, and colchicine have been investigated either in in silico or preliminary clinical studies to evaluate their anti-inflammatory effects against COVID-19. Sufficient pre-clinical studies on safety and efficacy of anti-inflammatory effects of the phytochemicals must be performed prior to proper clinical studies to develop them into therapeutic adjuvants in the prevention and treatmemt of COVID-19 symptoms.

Abstract
Originally identified in fibroblasts, Protease Inhibitor (PI)16 was recently shown to be crucial for the development of neuropathic pain via effects on blood-nerve barrier permeability and leukocyte infiltration, though its impact on inflammatory pain has not been established. Using the complete Freund's Adjuvant inflammatory pain model, we show that Pi16-/- mice are protected against sustained inflammatory pain. Accordingly, intrathecal delivery of a PI16 neutralizing antibody in wild-type mice prevented sustained CFA pain. In contrast to neuropathic pain models, we did not observe any changes in blood-nerve barrier permeability due to PI16 deletion. Instead, Pi16-/- mice display reduced macrophage density in the CFA-injected hindpaw. Furthermore, there was a significant bias toward CD206hi (anti-inflammatory) macrophages in the hindpaw and associated dorsal root ganglia. Following CFA, intrathecal depletion of CD206+ macrophages using mannosylated clodronate liposomes promoted sustained pain in Pi16-/- mice. Similarly, an IL-10 neutralizing antibody also promoted sustained CFA pain in the Pi16-/ when administered intrathecally. Collectively, our results point to fibroblast-derived PI16 mediating substantial differences in macrophage phenotype in the pain neuroaxis under conditions of inflammation. The co-expression of PI16 alongside fibroblast markers in human DRG raise the likelihood that a similar mechanism operates in human inflammatory pain states. Collectively, our findings may have implications for targeting fibroblast-immune cell crosstalk for the treatment of chronic pain.

Abstract
The worldwide spreading of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has posed a serious threat to health, economic, environmental, and social aspects of human lives. Currently, there are no approved treatments that can effectively block the virus although several existing antimalarial and antiviral agents have been repurposed and allowed use during the pandemic under the emergency use authorization (EUA) status. This review gives an updated overview of the antiviral effects of phytochemicals including alkaloids, flavonoids, and terpenoids against the COVID-19 virus and their mechanisms of action. Search for natural lead molecules against SARS-CoV-2 has been focusing on virtual screening and in vitro studies on phytochemicals that have shown great promise against other coronaviruses such as SARS-CoV. Until now, there is limited data on in vivo investigations to examine the antiviral activity of plants in SARS-CoV-2-infected animal models and the studies were performed using crude extracts. Further experimental and preclinical investigations on the in vivo effects of phytochemicals have to be performed to provide sufficient efficacy and safety data before clinical studies can be performed to develop them into COVID-19 drugs. Phytochemicals are potential sources of new chemical leads for the development of safe and potent anti-SARS-CoV-2 agents.

Abstract
Clavicle is an upper limb locomotory bone which helps in formation of pectoral girdle and connected the upper limb with axial skeleton. There is no baseline data of clavicle in contrast to demographic variation in our country, so the study was designed to obtain baseline data on clavicle for anthropological, forensic and clinical use. This descriptive cross-sectional study was done among 150 (65 right and 85 left) fully ossified dry human clavicle in Mymensingh Medical College, Mymensingh, Bangladesh from January 2020 to December 2020. Sample was collected by the help of nonrandom purposive sampling technique from Department of Anatomy of Mymensingh Medical College and Community Based Medical College, Bangladesh, Mymensingh. The parameters were the antero-posterior diameter and vertical diameter of sternal and acromial ends of clavicle, measured with the help of digital vernier slide caliper and expressed in millimeter. In the current study the mean±SD antero-posterior diameter of sternal end of 65 clavicles of right side was 21.97±2.889mm and 85 clavicles of left side were 20.30±3.459mm. The mean±SD antero-posterior diameter of acromial end of 65 right sided clavicles was 21.96±5.161mm and 85 clavicles of left side were 21.00±4.002mm. Correlation was done in between antero-posterior diameter and vertical diameter of sternal end of clavicle and the differences were highly significant on both sides. Similarly, when correlation was done for the acromial end of clavicle the difference was found non-significant on right side and highly significant on left side.

Abstract
Magnoflorine shows a diverse range of pharmacological actions, including immunomodulatory, antioxidant and neuropharmacological activities. However, its effects on the immune responses in animal studies have not been reported. In this study, magnoflorine isolated from Tinospora crispa, at doses of 25, 50 and 100 mg/kg was administered to male Balb/c mice daily for 14 days to evaluate its effect on innate immune responses, while for evaluation of adaptive immune responses, on day 0 the mice were injected intraperitoneally with sheep red blood cells (sRBC) and treated orally with the various doses of magnoflorine for the same duration. The effects of magnoflorine on phagocytosis, myeloperoxidase (MPO) activity, lysozyme serum level, nitric oxide (NO) production, CD4+ and CD8+ cells population, T and B lymphocytes proliferation, activated T cells cytokines production, antibodies levels and delayed type hypersensitivity (DTH) were determined. Magnoflorine dose-dependently stimulated NO production, E. coli engulfment by neutrophils and peritoneal macrophages, MPO activity and lysozyme serum level in treated mice. Magnoflorine at 100 mg/kg exhibited comparable stimulation of B cell production compared to levamisole at 2.5 mg/kg. It also significantly increased CD4+ and CD8+ cells population, upregulated the Th1 (IFN-γ, IL-2 and TNF-α) and Th2 (IL-4 and IL-6) cytokines in a dose-dependent manner. At similar concentrations, magnoflorine also exhibited a strong dose-dependent stimulation on DTH reaction and upregulation of immunoglobulins (IgG and IgM) production in mice immunized with sRBC. The strong upregulation of innate and adaptive immune responses indicates that magnoflorine has potential to be developed into an effective immunostimulant.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Peptic ulcer disease (PUD) ranks top among the most prominent gastrointestinal problems prevalent around the world. Long-term use of non-steroidal anti-inflammatory drugs, pathogenic infection by Helicobacter pylori, imbalances between gastrointestinal regulatory factors and pathological hyperacidity are major contributors towards the development of peptic ulcers. Although synthetic drugs of multiple pharmacological classes are abundantly available, inadequacy of such agents in ensuring complete recovery in not uncommon. Therefore, pharmacological explorations of herbal products including plant extracts and their respective isolated phytoconstituents, for potential gastroprotective and antiulcer properties, are regular practice among the scientific community. Moreover, the historical preferences of a significant share of world population towards herbal-based medication over modern synthetic drugs also contribute significantly to such endeavors. AIM OF THE REVIEW This review has endeavored to present ethnomedicinal and pharmacological prospects of a significant number of authenticated plant species in terms of their capacity to exert gastroprotection and antiulcer activities both in vitro and in vivo. The information delineated along the way was further subjected to critical analysis to ascertain the possible future prospects of such findings into designing plant-derived products in future for the treatment of peptic ulcer. MATERIALS AND METHODS Electronic version of prominent bibliographic databases, including Google Scholar, PubMed, Scopus, ScienceDirect, Wiley Online Library, SpringerLink, Web of Science, and MEDLINE were explored extensively for the identification and compilation of relevant information. The plant names and respective family names were verified through the Plant List (version 1.1) and World Flora Online 2021. All relevant chemical structures were verified through PubChem and SciFinder databases and illustrated with ChemDraw Ultra 12.0. RESULTS A colossal number of 97 plant species categorized under 58 diverse plant families have been discussed in the review for their gastroprotective and antiulcer properties. In vivo illustrations of the pharmacological properties were achieved for almost all the species under consideration. 29 individual phytoconstituents from these sources were also characterized with similar pharmacological potentials. Majority of the plant extracts as well as their constituents were found to exert their gastroprotective effects through antioxidative pathway featuring both enzymatic and nonenzymatic mechanism. Moreover, active inhibition of acid secretion, upregulation of gastroprotective mediators and downregulation of pro-inflammatory cytokines, were also associated with a prominent number of plants or products thereof. CONCLUSIONS Comparative evaluations of the plant sources for their antiulcer activities, both as individual and as combination formulations, are necessary to be conducted in human subjects under properly regulated clinical conditions. Moreover, the efficacy and safety of such products should also be evaluated against those of the currently available treatment options. This will further facilitate in ascertaining their suitability and superiority, if any, in the treatment of peptic ulcer diseases. Implementation of these endeavors may eventually lead to development of more efficient treatment options in the future.

Abstract
The genus Allium comprises of at least 918 species; the majority grown for dietary and medicinal purposes. This review describes the traditional uses, phytoconstituents, anti-inflammatory and anticancer activity, and safety profile of six main species, namely Allium sativum L. (garlic), Allium cepa L. (onions), Allium ampeloprasum L. (leek), Allium fistulosum L. (scallion), Allium schoenoprasum L. (chives) and Allium tuberosum Rottler (garlic chives). These species contain at least 260 phytoconstituents; mainly volatile compounds-including 63 organosulfur molecules-, saponins, flavonoids, anthocyanins, phenolic compounds, amino acids, organic acids, fatty acids, steroids, vitamins and nucleosides. They have prominent in vitro anti-inflammatory activity, and in vivo replications of such results have been achieved for all except for A. schoenoprasum. They also exert cytotoxicity against different cancer cell lines. Several anticancer phytoconstituents have been characterized from all except for A. fistulosum. Organosulfur constituents, saponins and flavonoid glycosides have demonstrated anti-inflammatory and anticancer activity. Extensive work has been conducted mainly on the anti-inflammatory and anticancer activity of A. sativum and A. cepa. The presence of anti-inflammatory and anticancer constituents in these two species suggests that similar bioactive constituents could be found in other species. This provides future avenues for identifying new Allium-derived anti-inflammatory and anticancer agents.

Abstract
Noonan syndrome is a genetic disorder of autosomal dominant inheritance that prevents normal development in various parts of the body. A spontaneous mutation without any family history may also result in the condition. Noonan syndrome can affect normal growth. Birth weight may be normal, but growth slows over time. The growth spurt usually seen during the teenage years may be delayed, and bone maturity also is delayed. In this case A 13 year's male admitted inpatient Department of Endocrinology, Mymensingh Medical College Hospital in April 2021 with not attaining appropriate height and delayed development of secondary sexual characteristics. His birth weight was normal; gestational and neonatal history was uneventful. He was diagnosed with severe pulmonary stenosis at four years and underwent cardiac surgery at his four and eleven years. He was noted to have growth failure from the age of 9 years onward. He had no family history of such type of disease. On examination, he was short statured, underweight, having an upper: lower segment ratio of 1.05 with an arm span of 126cm. He had craniosynostosis, high arched palate, the thick helix of ears (outer rim), small, upturned nose, depressed broad nose, deeply grooved philtrum, keratosis pilaris of the face and upper arm, slant eyes with proptosis, keloid scar over mid-chest, widely spaced nipple, shield chest, pectus excavatum and cubitus valgus. His sexual maturation score was A1, P1, B1. He had pulmonary stenosis with pulmonary hypertension. He had mild microcytic anemia with normal liver, renal, blood glucose, and calcium profile. His bone age was delayed (9 years), thyroid function was normal. The growth hormone dynamic test after clonidine stimulation was normal. His karyotype was 46XY. We have considered giving recombinant growth hormone therapy to accelerate his height.

Abstract
Medicinally important plant-foods offer a balanced immune function, which is essential for protecting the body against antigenic invasion, mainly by microorganisms. Immunomodulators play pivotal roles in supporting immune function either suppressing or stimulating the immune system's response to invading pathogens. Among different immunomodulators, plant-based secondary metabolites have emerged as high potential not only for immune defense but also for cellular immunoresponsiveness. These natural immunomodulators can be developed into safer alternatives to the clinically used immunosuppressants and immunostimulant cytotoxic drugs which possess serious side effects. Many plants of different species have been reported to possess strong immunomodulating properties. The immunomodulatory effects of plant extracts and their bioactive metabolites have been suggested due to their diverse mechanisms of modulation of the complex immune system and their multifarious molecular targets. Phytochemicals such as alkaloids, flavonoids, terpenoids, carbohydrates and polyphenols have been reported as responsible for the immunomodulatory effects of several medicinal plants. This review illustrates the potent immunomodulatory effects of 65 plant secondary metabolites, including dietary compounds and their underlying mechanisms of action on cellular and humoral immune functions in in vitro and in vivo studies. The clinical potential of some of the compounds to be used for various immune-related disorders is highlighted.

DC. is a perennial shrub indigenous to the tropical and subtropical regions of India, China, Sri Lanka, Myanmar, Bangladesh, Indonesia, Malaysia, Thailand, Vietnam, Philippine, Java, Sumatra, Borneo and Australia. The plant is used extensively within these regions as a traditional medicine for the treatment of a variety of ailments including cough, fever, chest pain, anemia, jaundice, liver disorders, inflammation, bronchitis, rheumatism, urinary tract infections, pain, bone fractures, toothache, gonorrhea, diabetes, cancer and other chronic diseases. AIM OF THE REVIEW This review aims to present up-to-date information regarding the taxonomy, botany, distribution, ethnomedicinal uses, phytochemistry, pharmacology and toxicological profile of G. pentaphylla. The presented information was analyzed critically to understand current work undertaken on this species and explore possible future prospects for this plant in pharmaceutical research. MATERIALS & METHODS Bibliographic databases, including Google Scholar, PubMed, Web of Science, ScienceDirect, SpringerLink, Wiley Online Library, Semantic Scholar, Europe PMC, Scopus, and MEDLINE, were explored thoroughly for the collection of relevant information. The structures of phytoconstituents were confirmed with PubChem and SciFinder databases. Taxonomical information on the plant was presented in accordance with The Plant List (version 1.1). RESULTS Extensive phytochemical investigations into different parts of G. pentaphylla have revealed the presence of at least 354 secondary metabolites belonging to structurally diverse classes including alkaloids, amides, phenolic compounds, flavonoids, glycosides, aromatic compounds, steroids, terpenoids, and fatty derivatives. A large number of in vitro and in vivo experiments have demonstrated that G. pentaphylla had anticancer, antimutagenic, antibacterial, antifungal, anthelmintic, mosquitocidal, antidiabetic, antihyperlipidemic, anti-oxidant, anti-inflammatory, analgesic, antipyretic, anti-arsenicosis, and wound healing properties. Toxicological studies have established the absence of any significant adverse reactions and showed that the plant had a moderate safety profile. CONCLUSIONS G. pentaphylla can be suggested as a source of inspiration for the development of novel drugs, especially anticancer, antimicrobial, anthelmintic, and mosquitocidal agents. Moreover, bioassay-guided investigations into its diverse classes of secondary metabolites, especially the large pool of nitrogen-containing alkaloids and amides, promises the development of novel drug candidates. Future pharmacological studies into this species are also warranted as many of its traditional uses are yet to be validated scientifically.

Abstract
Hepatitis B virus infection is an important cause of liver disease. Hepatitis B Virus may present with varying degree of severity. In older children, 5-10% cases leading to chronic liver disease, cirrhosis and hepatocellular carcinoma. This descriptive cross sectional study was done to assess the prevalence of Hepatitis B Virus infection among hospitalized children with liver disease in pediatric department of Mymensingh Medical College Hospital, Bangladesh from December 2015 to October 2016. All the children of both sexes having age between six months to twelve years admitted in the pediatric ward with acute or chronic liver disease were included in this study by purposive sampling. A written consent was obtained from legal guardian of children before inclusion. Ethical clearance was obtained from competent authority. A detailed history was taken from parents in each case according to pre-designed questionnaire about demography of the patients and the risk factors of the liver disease. A thorough clinical examination and available relevant investigations like serological testing for HBV infection was done in all patients. We had figure out the seropositivity of HBV among patients having liver disease by doing HBsAg and Anti-HBc IgM. Progress of the patient was monitored by daily clinical examinations and by investigating HBsAg and Anti-HBc IgM. Finally data analysis was done by SPSS version 21.0. Among total 100 patients most (44%) patients were in 7-10 years old and most (62%) of the participants were male. Acute liver disease was 58% cases and chronic liver disease was 42% cases. HBsAg was positive in 1 case among acute liver disease and 5 cases among chronic cases. Total 6 (six) patients were found positive for HBsAg. Anti HBc IgM was positive in 4 patients among acute liver disease. Among these Anti HBc IgM positive (4) patients only one had both HBsAg and Anti HBc IgM positive. So, four patients were confirming suffered from acute viral hepatitis because they had anti HBc IgM positive. On the contrary 5 patients suffered from chronic hepatitis by hepatitis B because they were only HBsAg positive. So, in this study 9 patients (9%) were confirming suffered from HBV infection. Possible transmission factors of hepatitis B were history of (H/O) blood transfusion/trauma/parenteral injection, H/O umbilical sepsis, H/O maternal illness/infection during pregnancy. HBV still is a major cause of morbidity. All the children with liver disease should be routinely tested for HBV.

Abstract
This prospective study was conducted to find the rate of deep and risk factors associated with vein thrombosis following major abdominal surgery in Sylhet MAG Osmani Medical College Hospital from 1st November 2017 to 30th April 2018. Total 103 patients aged above 20 years both male and female who got admitted in Department of Surgery, Sylhet MAG Osmani Medical College Hospital, Sylhet for their disease requiring routine and emergency major abdominal operation during the study period and fulfilling the inclusion and exclusion criteria were selected in this study. Informed written consent was obtained from the patients after full explanation of the purpose of the study. After full investigations and proper preparation of each patient for operative procedure major abdominal surgery were done. Peroperative findings were noted and post-operative period were followed up routinely. Duplex scanning was done on 3rd POD in all cases. The age of the patients ranged from 25 to 74 years with the mean age of 49.5±13.8 years. There were 60(58.3%) male and 43(41.7%) female. Deep vein thrombosis (DVT) developed in 5(4.9%) of cases and not developed in 98(95.1%) cases. All the five cases were confirmed by color duplex scan. DVT was detected in 2(3.3%) of the 60 males and 3(7.0%) of the 43 females undergoing major general surgical procedures. Among 63 patients in whom the duration of surgery was up to 2 hours, none developed DVT, while among the 40 patients in whom the duration of surgery lasted more than 2 hours, 5(12.5%) developed DVT. Among 23 patients in whom the surgery for malignancy was done, 4(17.4%) developed DVT, while among the 80 patients in whom surgery for non-malignancy, 1(1.2%) developed DVT. The Incidence of DVT in patients undergoing major abdominal surgery is 4.9%. Patients undergoing major abdominal surgery for malignancy and duration of operation greater than 2 hours have higher risk of developing DVT. But there is no significant increase in risk of development of DVT relation to age and sex; and also in patients on oral contraceptives, diabetes mellitus, obesity and smoking. Clinical findings alone cannot be relied upon for the diagnosis of DVT. The study has to be continued with larger sample size to get statistically significant results.

Abstract
Climate change-induced salinity intrusion into agricultural soils is known to negatively impact crop production and food security. However, the effects of salinity increase on plant-herbivore-natural enemy systems and repercussions for pest suppression services are largely unknown. Here, we examine the effects of increased salinity on communities of rice (Oryza sativa), brown planthopper (BPH), Nilaparvata lugens, and green mirid bug (GMB), Cyrtorhinus lividipennis, under greenhouse conditions. We found that elevated salinity significantly suppressed the growth of two rice cultivars. Meanwhile, BPH population size also generally decreased due to poor host plant quality induced by elevated salinity. The highest BPH density occurred at 2.0 dS/m salinity and declined thereafter with increasing salinity, irrespective of rice cultivar. The highest population density of GMB also occurred under control conditions and decreased significantly with increasing salinity. Higher salinity directly affected the rice crop by reducing plant quality measured with reference to biomass production and plant height, whereas inducing population developmental asynchrony between BPH and GMB observed at 2 dS/m salinity and potentially uncoupling prey-predator dynamics. Our results suggest that increased salinity has harmful effects on plants, herbivores, natural enemies, as well as plant-pest-predator interactions. The effects measured here suggest that the bottom-up effects of predatory insects on rice pests will likely decline in rice produced in coastal areas where salinity intrusion is common. Our findings indicate that elevated salinity influences tritrophic interactions in rice production landscapes, and further research should address resilient rice insect pest management combining multipests and predators in a changing environment.

Abstract
This cross sectional comparative analytical study was undertaken with the objectives to find out the nutritional status of children with congenital heart disease by anthropometric measurement and was compared it with those of children having minor illness and without any congenital heart disease in indoor and outdoor Department of Paediatrics of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from December 2015 to November 2016. Purposive sampling was done. One hundred children aged 6 to 60 months with congenital heart disease confirmed by echocardiogram were taken as Group A and one hundred children of same age and sex matched having minor illness and without any congenital heart disease were taken as Group B. Age of the patients ranged from 6 to 60 months. There was no obvious difference of socio-demographic status between two groups. Most of the patient (64.0%) had acyanotic congenital heart disease among them VSD was commonest (68.8%). Thirty-six percent (36.0%) patient had cyanotic congenital heart disease and among them Tetralogy of Fallots (83.3%) was commonest. There were significant differences regarding weight, height and MUAC values in between two Groups. Underweight (51%), Stunting (50%) and Wasting (29%) all were higher in congenital heart disease than that of Group B where they were 28%, 31% and 13% respectively and the differences were statistically significant (p<0.05). The findings of this study imply that malnutrition is very common among children with congenital heart disease. So, anthropometric measurement should be done in each and every child with congenital heart disease.

Abstract
This investigation presents the food and feeding activity of and endangered riverine catfish Rita rita, during February 2017-January 2018. A total of 225 fish individuals was analyzed for stomach contents by characterizing the dominant food items and morphometric features. The results divulged ten major food items consumed, preferably fish scales and eggs, teleost fishes, copepods, cladocerans, rotifers, and mollusks. Total length and body weight of fish varied between 9-34 cm (20.53 ± 6.90 cm) and 10-400 g (9125.94 ± 102.07 g), respectively. The index of relative importance (IRI%) showed the importance of rotifers over the other food items. Morisita's index of diet overlap indicated seasonal variations in catfish diets with summer and monsoon displaying the least overlap, while maximum overlap during monsoon and winter seasons. The non-metric multidimensional scaling (nMDS) indicated the close association between the food items available during summer and winter seasons with a significant difference among the seasons (ANOSIM, R = 0.638, P = 0.013). Levin's niche breadth index arranged in the order of 0.88>0.81>0.78>0.63>0.43 for the size classes of V, IV, III, II and I, respectively. The PCA explained 95.39% of the total variance among the food items and fish size groups. Small-sized fish individuals displayed a greater correlation with food items suitable for their mouth size. In conclusion, the variety and frequency of food items recorded indicated considerable feeding plasticity and opportunistic feeding behavior with a shift from carnivorous to omnivorous feeding nature. This study could render useful information on the food and feeding habits of R. rita and provide background for preparing its diet for future aquaculture practices.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Gynura (Compositae) includes around 46 species and is native to the tropical regions of Southeast Asia, Africa and Australia. Many species within this genus are used in ethnomedicine to treat various disorders including skin diseases, injuries, ulcers, wounds, burns, sores, scalds, as well as for the management of diabetes, hypertension, hyperlipidemia, constipation, rheumatism, bronchitis and inflammation. AIM OF THE REVIEW This review is an attempt to provide scientific information regarding the ethnopharmacology, phytochemistry, pharmacological and toxicological profiles of Gynura species along with the nomenclature, distribution, taxonomy and botanical features of the genus. A critical analysis has been undertaken to understand the current and future pharmaceutical prospects of the genus. MATERIALS & METHODS Several electronic databases, including Google scholar, PubMed, Web of Science, Scopus, ScienceDirect, SpringerLink, Semantic Scholar, MEDLINE and CNKI Scholar, were explored as information sources. The Plant List Index was used for taxonomical authentications. SciFinder and PubChem assisted in the verification of chemical structures. RESULTS A large number of phytochemical analyses on Gynura have revealed the presence of around 342 phytoconstituents including pyrrolizidine alkaloids, phenolic compounds, chromanones, phenylpropanoid glycosides, flavonoids, flavonoid glycosides, steroids, steroidal glycosides, cerebrosides, carotenoids, triterpenes, mono- and sesquiterpenes, norisoprenoids, oligosaccharides, polysaccharides and proteins. Several in vitro and in vivo studies have demonstrated the pharmacological potential of Gynura species, including antidiabetic, anti-oxidant, anti-inflammatory, antimicrobial, antihypertensive and anticancer activities. Although the presence of pyrrolizidine alkaloids within a few species has been associated with possible hepatotoxicity, most of the common species have a good safety profile. CONCLUSIONS The importance of the genus Gynura both as a prominent contributor in ethnomedicinal systems as well as a source of promising bioactive molecules is evident. Only about one fourth of Gynura species have been studied so far. This review aims to provide some scientific basis for future endeavors, including in-depth biological and chemical investigations into already studied species as well as other lesser known species of Gynura.

Abstract
Obesity is an enduring medical issue that has raised concerns around the world. Natural plant extracts have shown therapeutic potential in preventing oxidative stress and inflammation related to obesity complications. In this study, Senna alexandrina Mill. leaves were utilized to treat high-fat diet-related metabolic disorders and non-alcoholic fatty liver diseases. Plasma biochemical assays were conducted to determine the lipid profiles and oxidative stress parameters, and the gene expression of antioxidant enzymes and inflammatory mediators was measured. Histological stained livers of high-fat diet-fed rats were observed. S. alexandrina leaf powder supplementation prevented the increase in cholesterol and triglyceride levels in high-fat diet-fed rats. Moreover, S. alexandrina leaves also reduced lipid peroxidation and nitric oxide production in these rats. Prevention of oxidative stress by S. alexandrina leaf supplementation in high-fat diet-fed rats is regulated by enhancing the antioxidant enzyme activity, followed by the restoration of corresponding gene expressions, such as NRF-2, HO-1, SOD, and CAT. Histological staining provides further evidence that S. alexandrina leaf supplementation prevents inflammatory cell infiltration, lipid droplet deposition, and fibrosis in the liver of high-fat diet-fed rats. Furthermore, this investigation revealed that S. alexandrina leaf supplementation controlled non-alcoholic fatty liver disease by modulating the expression of fat metabolizing enzymes in high-fat diet-fed rats. Therefore, S. alexandrina leaf supplementation inhibits fatty liver inflammation and fibrosis, suggesting its usefulness in treating non-alcoholic steatohepatitis. Thus, this natural leaf extract has potential in treatment of obesity related liver dysfunction.

Abstract
Type 2 Diabetes mellitus (DM) is associated with various types of liver disorders including elevated liver enzymes. This study was carried out to observe hepatocellular injury in type 2 Diabetes mellitus as evidenced by raised Alanine aminotransferase (ALT) among the type 2 Diabetes mellitus patients and to find out association between elevated ALT and glycaemic control. This was a descriptive cross-sectional comparative study carried out in Department of Medicine, Rajshahi Medical College Hospital and Rajshahi Diabetic Association Hospital, Rajshahi, Bangladesh from July 2009 to June 2010. One hundred (100) diagnosed type 2 diabetic patients according to WHO criteria and 30 apparently healthy people of both sexes were included. Age of the study people were >40 years. All of those study population were free from taking any hepatotoxic drugs, inj. Insulin, alcohol and preexisting liver disease. Detailed History, thorough clinical examination and relevant investigations were done for exclusion. The frequency of abnormal ALT, Serum bilirubin, Aspartate aminotransferase (AST), Alkaline phosphatase, Prothrombin time and Serum albumin were 30%, 6%, 7%, 6%, 54% and 12% respectively in type 2 diabetic patients and 3.3%, 00%, 00%, 6.7%, 10% and 3.3% respectively in normal people. Serum ALT (U/L) level (mean±SD) of the type 2 diabetic patients and normal people were (39.00±24.21) and (28.26±6.67) respectively. This difference is highly significant (p<0.001). Elevated serum ALT level of type 2 diabetic patients showed positive association with increased Body mass index (BMI) (p<0.05) and poor glycaemic control (p<0.05) and fatty liver (p=0.055). So, a high proportion of patients with type 2 diabetes mellitus have raised serum Alanine aminotransferase level. Elevated serum ALT level was also associated with high BMI, poor glycaemic control and fatty liver which may be a marker of NAFLD and insulin resistance.

Abstract
The high failure rate of the reductionist approach to discover effective and safe drugs to treat chronic inflammatory diseases has led scientists to seek alternative ways. Recently, targeting cell signaling pathways has been utilized as an innovative approach to discover drug leads from natural products. Cell signaling mechanisms have been identified playing key role in diverse diseases by inducing proliferation, cell survival and apoptosis. Phytochemicals are known to be able to modulate the cellular and molecular networks which are associated to chronic diseases including cancer-associated inflammation. In this review, the roles of dietary polyphenols (apigenin, kaempferol, quercetin, curcumin, genistein, isoliquiritigenin, resveratrol and gallic acid) in modulating multiple inflammation-associated cell signaling networks are deliberated. Scientific databases on suppressive effects of the polyphenols on chronic inflammation via modulation of the pathways especially in the recent five years are gathered and critically analyzed. The polyphenols are able to modulate several inflammation-associated cell signaling pathways, namely nuclear factor-kappa β, mitogen activated protein kinases, Wnt/β-catenin and phosphatidylinositol 3-kinase and protein kinase B via selective actions on various components of the networks. The suppressive effects of the polyphenols on the multiple cell signaling pathways reveal their potential use in prevention and treatment of chronic inflammatory disorders. Understanding the mechanistic effects involved in modulation of the signaling pathways by the polyphenols is necessary for lead identification and development of future functional foods for prevention and treatment of chronic inflammatory diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aglaonema hookerianum Schott is an ethnomedicinally important plant used to treat a variety of diseases, including sexual and depression-like disorders. However, the scientific basis underlying the aforesaid properties have not been well justified. AIM OF THE STUDY The present investigation aimed to investigate the anxiolytic, antidepressant and aphrodisiac potentials of methanol leaves extract of A. hookerianum (MEAH) in Swiss albino mice. MATERIALS & METHODS Swiss albino mice (20-30 g) were orally administrated with MEAH at the doses ranging from 100 to 400 mg/kg, b.w. The elevated plus maze (EPM) and hole board test (HBT) were performed to determine the anxiolytic activity and the forced swimming test (FST) and tail suspension test (TST) were performed to determine the antidepressant activity of MEAH. Besides, the aphrodisiac activity of MEAH was conducted through the mounting behaviour and orientation behaviour analysis. Diazepam (1 mg/kg, b.w., i.p.) for EPM and HBT; fluoxetine HCl (20 mg/kg, b.w., p.o.) for FST and TST, and sildenafil (5 mg/kg, b.w., p.o.) for the mounting behaviour analysis and orientation behaviour analysis were used as reference drugs. RESULTS The administration of the MEAH produced a strong (p < 0.001) dose-dependent anxiolytic effects in both HBT and EPM tests. Likewise, the extract revealed a significant (p < 0.001) reduction in the immobility time in both FST and TST as compared to the control group. Besides, the MEAH also found to possess marked aphrodisiac activity complying several facets such as an increase in the sexual performance at the highest dose (400 mg/kg, p.o.) as well as the orientation toward female mice (p < 0.001) at all tested doses. CONCLUSION Taken together, MEAH can be recommended as a potent source of neuroprotective and a libido-boosting drug candidate for the management of neurological and sexual disorders.

Abstract
Aphanamixis polystachya (Wall.) R.Parker, locally known as Pithraj, is a medicinal herb having enormous traditional applications. However, the scientific rationale underlying the ethnomedicinal claims was not well-founded. The current investigation aimed to explore the mechanistic insights of protective effects of ethanol extract of A. polystachya leaf (PT), given orally, on the chemical-intoxicated hepatic inflammation and fibrosis in Long-Evans female overiectomized rats. The GC-MS and HPLC-DAD analysis of PT revealed the presence of several bioactive metabolites, including polyphenolic compounds. Catechin hydrate, caffeic acid, syringic acid, epicatechin and p-coumaric acid have been identified and quantified in the ethanol extract of PT leaf. Intoxication with CCl4 developed the oxidative stress, fibrosis and inflammation in liver of rats. Moreover, thiobarbituric acid reactive substances (TBARS), nitric oxide (NO), advanced protein oxidation product (APOP) level were found increased; whereas superoxide dismutase (SOD) and catalase activities in the plasma and liver were decreased in CCl4 administered rats. Treatment with PT prominently mitigated the oxidative stress (TBARS, NO, APOP), and inflammatory (MPO) markers and improved the endogenous antioxidant enzymes (catalase and SOD) activities in CCl4-intoxicated rats. Additionally, histological assessment confirmed the clear manifestation of inflammation and fibrosis in the liver of CCl4-intoxicated rats, which was prevented by PT and silymarin treatment. In conclusion, PT treatment may protect the liver in CCl4-administered rats, probably by mitigating oxidative stress, inflammation and fibrosis, and also augmenting the function of the antioxidant enzymes.

Abstract
Dita bark (Alstonia scholaris (L.) R. Br.) is an ethnomedicine used for the management of various ailments. This study aimed to investigate the biological properties of methanol extract of A. scholaris bark (MEAS), through in vivo, in vitro and in silico approaches alongside its phytochemical profiling. Identification and nature of the bioactive secondary metabolites were studied by the established qualitative tests and GC-MS analysis. The antidepressant activity was determined by forced swimming test (FST) and tail suspension test (TST) in mice. The anti-inflammatory and thrombolytic effect was evaluated using inhibition of protein denaturation technique and clot lysis technique, respectively. Besides, computational studies of the isolated compounds and ADME/T analysis were performed by Schrödinger-Maestro (v11.1) software, and PASS prediction was conducted through PASS online tools. The GC-MS analysis revealed the presence of several secondary metabolites in MEAS. Treatment with MEAS revealed a significant reduction of immobility time in a dose-dependent manner in FST and TST. Besides, MEAS showed substantial anti-inflammatory effects at the higher dose (400 μg/mL) as well as revealed notable clot lysis effect as compared to control. In the case of computer-aided investigation, all compounds meet the condition of Lipinski's rule of five. PASS study also predicted for all compounds, and among these safe compound furazan-3-amine showed the most spontaneous binding energy for both antidepressant and thrombolytic activities, as well as 5-dimethylamino-6 azauracil, found promising for anti-inflammatory activity. Taken together, the investigation concludes that MEAS can be a potent source of antidepressant, anti-inflammatory, and thrombolytic agents.

Abstract
BACKGROUND Immunomodulatory effects of Tinospora crispa have been investigated due to its traditional use to treat several inflammatory disorders associated to the immune system. The present study reports the underlying mechanisms involved in the stimulation of 80% ethanol extract of T. crispa stems on pro-inflammatory mediators release in lipopolysaccharide (LPS)-primed U937 human macrophages via MyD88-dependent pathways. METHODS Release of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, and production of prostaglandin E2 (PGE2) were determined by using enzyme-linked immunosorbent assay (ELISA). Immunoblot technique was executed to determine the activation of MAPKs molecules, NF-κB, PI3K-Akt and cyclooxygenase-2 (COX-2) protein. Determination of pro-inflammatory cytokines and COX-2 relative gene expression levels was by performing the real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). A reversed-phase HPLC method was developed and validated to standardize the T. crispa extract and chemical profiling of its secondary metabolites was performed by LC-MS/MS. RESULTS Qualitative and quantitative analyses of chromatographic data indicated that syringin and magnoflorine were found as the major components of the extract. T. crispa-treatment prompted activation of NF-κB by enhancing IKKα/β and NF-κB (p65) phosphorylation, and degradation of IκBα. The extract upregulated COX-2 protein expression, release of pro-inflammatory mediators and MAPKs (ERK, p38 and JNK) phosphorylation as well as Akt dose-dependently. T. crispa extract also upregulated the upstream signaling adaptor molecules, toll-like receptor 4 (TLR4) and MyD88. T. crispa-treatment also upregulated the pro-inflammatory markers mRNA expression. CONCLUSION The results suggested that T. crispa extract stimulated the MyD88-dependent signaling pathways by upregulating the various immune inflammatory related parameters.

Abstract
The causal and functional connection between inflammation and cancer has become a subject of much research interest. Modulation of cell signaling pathways, such as those involving mitogen activated protein kinases (MAPKs), nuclear factor kappa β (NF-κB), phosphatidylinositol 3-kinase and protein kinase B (PI3K/Akt), and Wnt, and their outcomes play a fundamental role in inflammation and cancer. Activation of these cell signaling pathways can lead to various aspects of cancer-related inflammation. Hence, compounds able to modulate inflammation-related molecular targets are sought after in anticancer drug development programs. In recent years, plant extracts and their metabolites have been documented with potential in the prevention and treatment of cancer and inflammatory ailments. Plants possessing anticancer and anti-inflammatory properties due to their bioactive constituents have been reported to modulate the molecular and cellular pathways which are related to inflammation and cancer. In this review we focus on the flavonoids (astragalin, kaempferol, quercetin, rutin), lignans (phyllanthin, hypophyllanthin, and niranthin), tannins (corilagin, geraniin, ellagic acid, gallic acid), and triterpenes (lupeol, oleanolic acid, ursolic acid) of Phyllanthus amarus, which exert various anticancer and anti-inflammatory activities via perturbation of the NF-κB, MAPKs, PI3K/Akt, and Wnt signaling networks. Understanding the underlying mechanisms involved may help future research to develop drug candidates for prevention and new treatment for cancer and inflammatory diseases.

Abstract
Zerumbone exhibited various biological properties including in vitro immunosuppressive effects. However, its modulatory activity on the immune responses in experimental animal model is largely unknown. This investigation was conducted to explore the effects of daily treatment of zerumbone (25, 50, and 100 mg/kg) isolated from Zingiber zerumbet rhizomes for 14 days on various cellular and humoral immune responses in Balb/C mice. For measurement of adaptive immunity, sheep red blood cells (sRBC) were used to immunize the mice on day 0 and orally fed with similar doses of zerumbone for 14 days. The effects of zerumbone on phagocytosis, nitric oxide (NO) release, myeloperoxidase (MPO) activity, proliferation of T and B cells, lymphocyte phenotyping, cytokines release in serum by activated T cells, delayed type hypersensitivity (DTH) and immunoglobulins production (IgG and IgM) were investigated. Zerumbone downregulated the engulfment of E. coli by peritoneal macrophages and the release of NO and MPO in a concentration-dependent manner. Zerumbone showed significant and concentration-dependent suppression of T and B lymphocytes proliferation and inhibition of the Th1 and Th2 cytokines release. At higher concentrations of zerumbone, the % expression of CD4+ and CD8+ in splenocytes was significantly inhibited. Zerumbone also concentration-dependently demonstrated strong suppression on sRBC-triggered swelling of mice paw in DTH. Substantial suppression of anti-sRBC immunoglobulins antibody titer was noted in immunized and zerumbone-treated mice in a concentration-dependent manner. The potent suppressive effects of zerumbone on the immune responses suggest that zerumbone can be a potential candidate for development of immunosuppressive agent.

Abstract
BACKGROUND Zingiber zerumbet rhizome has been used as spices and in traditional medicine to heal various immune-inflammatory related ailments. Although the plant was reported to have potent anti-inflammatory and immunosuppressive properties by several studies, the molecular mechanisms underlying the effects have not been well justified. PURPOSE The study was carried out to investigate the molecular mechanisms underlying the anti-inflammatory properties of the standardized 80% ethanol extract of Z. zerumbet through its effect on mitogen-activated protein kinase (MyD88)-dependent nuclear factor-kappa B (NF-кB), mitogen activated protein kinase (MAPK) and phosphatidylinositol 3-kinase/Akt (PI3K-Akt) signaling pathways in lipopolysaccharide (LPS)-induced U937 human macrophages. METHODS Standardization of the 80% ethanol extract of Z. zerumbet was performed by using a validated reversed-phase HPLC method, while LC-MS/MS was used to profile the secondary metabolites. The release of pro-inflammatory markers, tumor necrosis factor (TNF)-α, interleukin (IL)-1β and prostaglandin E2 (PGE2) was evaluated by enzyme-linked immunosorbent assay (ELISA), while the Western blot technique was executed to elucidate the expression of mediators linked to MyD88-dependent respective signaling pathways. Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) assay was carried out to quantify the relative gene expression of cyclooxygenase (COX)-2 and pro-inflammatory mediators at the transcriptional level. RESULTS The quantitative and qualitative analyses of Z. zerumbet extract showed the presence of several compounds including the major chemical marker zerumbone. Z. zerumbet extract suppressed the release of pro-inflammatory mediators, COX-2 protein expression and downregulated the mRNA expression of pro-inflammatory markers. Z. zerumbet-treatment also blocked NF-κB activation by preventing the phosphorylation of IKKα/β and NF-κB (p65) as well as the phosphorylation and degradation of IκBα. Z. zerumbet extract concentration-dependently inhibited the phosphorylation of respective MAPKs (JNK, ERK, and p38) as well as Akt. Correspondingly, Z. zerumbet extract suppressed the upstream signaling adaptor molecules, TLR4 and MyD88 prerequisite for the NF-κB, MAPKs, and PI3K-Akt activation. CONCLUSION The findings suggest that Z. zerumbet has impressive role in suppressing inflammation and related immune disorders by inhibition of various pro-inflammatory markers through the imperative MyD88-dependent NF-κB, MAPKs, and PI3K-Akt activation.

Abstract
Zingiber zerumbet rhizome has been used in traditional medicine mainly for the treatment of various immune-inflammatory related ailments and has been shown to exhibit a wide spectrum of biological effects especially antioxidant and anti-inflammatory activities. The present study was aimed to investigate the immunosuppressive effects of the standardized 80% ethanol extract of Z. zerumbet at 100, 200, and 400 mg/kg on the innate immune responses in male Wistar rats. The immune parameters determined were chemotaxis of neutrophils, Mac-1 expression, engulfment of Escherichia coli by neutrophils, reactive oxygen species production, and plasma lysozyme and ceruloplasmin levels. Zerumbone was qualitatively and quantitatively determined in the extract by using a validated reversed-phase HPLC, whereas liquid chromatography tandem-mass spectrometry (LC -MS/MS) was used to profile the secondary metabolites. Z. zerumbet significantly inhibited the migration of neutrophils, expressions of CD11b/CD18 integrin, phagocytic activity, and production of reactive oxygen species in a dose-dependent manner. The extract also dose-dependently inhibited the expressions of lysozyme and ceruloplasmin in the rat plasma. Z. zerumbet extract possessed strong inhibitory effects on the innate immune responses and has potential to be developed into an effective immunosuppressive agent.

Abstract
Magnoflorine, a major bioactive metabolite isolated from Tinospora crispa, has been reported for its diverse biochemical and pharmacological properties. However, there is little report on its underlying mechanisms of action on immune responses, particularly on macrophage activation. In this study, we aimed to investigate the effects of magnoflorine, isolated from T. crispa on the pro-inflammatory mediators generation induced by LPS and the concomitant NF-κB, MAPKs, and PI3K-Akt signaling pathways in U937 macrophages. Differentiated U937 macrophages were treated with magnoflorine and the release of pro-inflammatory mediators was evaluated through ELISA, while the relative mRNA expression of the respective mediators was quantified through qRT-PCR. Correspondingly, western blotting was executed to observe the modulatory effects of magnoflorine on the expression of various markers related to NF-κB, MAPK and PI3K-Akt signaling activation in LPS-primed U937 macrophages. Magnoflorine significantly enhanced the upregulation of TNF-α, IL-1β, and PGE2 production as well as COX-2 protein expression. Successively, magnoflorine prompted the mRNA transcription level of these pro-inflammatory mediators. Magnoflorine enhanced the NF-κB activation by prompting p65, IκBα, and IKKα/β phosphorylation as well as IκBα degradation. Besides, magnoflorine treatments concentration-dependently augmented the phosphorylation of JNK, ERK, and p38 MAPKs as well as Akt. The immunoaugmenting effects were further confirmed by investigating the effects of magnoflorine on specific inhibitors, where the treatment with specific inhibitors of NF-κB, MAPKs, and PI3K-Akt proficiently blocked the magnoflorine-triggered TNF-α release and COX-2 expression. Magnoflorine furthermore enhanced the MyD88 and TLR4 upregulation. The results suggest that magnoflorine has high potential on augmenting immune responses.

Abstract
Hypophyllanthin (HYP) and niranthin (NIR) are major lignans in Phyllanthus spp. and have been shown to possess strong anti-inflammatory activity. In this study, we investigated the anti-inflammatory effects and the underlying molecular mechanisms of HYP and NIR in in vitro cellular model of LPS-induced U937 macrophages. The effects of HYP and NIR on the production of prostaglandin E2 (PGE2), cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) were measured by using ELISA, Western blot, and qRT-PCR. The expressions of signaling molecules related to nuclear factor-kappa B (NF-κB), mitogen-activated protein kinases (MAPKs), and phosphatidylinositol 3'-kinase-Akt (PI3K-Akt) signaling pathways were examined. The role of NF-κB, MAPKs, and Akt signaling pathways was confirmed by using specific inhibitors (BAY 11-7082, U0126, SB202190, SP600125, and LY294002) mediated suppression of TNF-α and COX-2 production. HYP and NIR significantly inhibited the protein and gene levels of COX-2 as well as the downstream signaling products of PGE2, TNF-α, and IL-1β. HYP and NIR also suppressed the inhibitors of kappa B (IκB), IkB kinases (Ikkα/β), NF-κB phosphorylation, and IκB degradation. HYP suppressed the phosphorylation of c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK), and p38 while NIR only suppressed JNK and ERK but did not have effect on p38. These results demonstrate that HYP and NIR downregulated COX-2, TNF-α, and IL-1β gene expressions in U937 macrophages by interfering with the activation of NF-κB, MAPKs, and Akt. In conclusion, these lignans have potential to be developed as anti-inflammatory agents targeting the NF-κB, MAPK, and PI3K-Akt pathways.

Abstract
Bacterial biofilm plays a pivotal role in bioremediation of heavy metals from wastewaters. In this study, we isolated and identified different biofilm producing bacteria from wastewaters. We also characterized the biofilm matrix [i.e., extracellular polymeric substances (EPS)] produced by different bacteria. Out of 40 isolates from different wastewaters, only 11 (27.5%) isolates (static condition at 28°C) and 9 (22.5%) isolates (agitate and static conditions at 28 and 37°C) produced air–liquid (AL) and solid–air–liquid (SAL) biofilms, respectively, only on salt-optimized broth plus 2% glycerol (SOBG) but not in other media tested. Biomass biofilms and bacteria coupled with AL biofilms were significantly (P ≤ 0.001) varied in these isolates. Escherichia coli (isolate ENSD101 and ENST501), Enterobacter asburiae (ENSD102), Enterobacter ludwigii (ENSH201), Pseudomonas fluorescens (ENSH202 and ENSG304), uncultured Vitreoscilla sp. (ENSG301 and ENSG305), Acinetobacter lwoffii (ENSG302), Klebsiella pneumoniae (ENSG303), and Bacillus thuringiensis (ENSW401) were identified based on 16S rRNA gene sequencing. Scanning electron microscope (SEM) images revealed that biofilm matrix produced by E. asburiae ENSD102, uncultured Vitreoscilla sp. ENSG301, A. lwoffii ENSG302, and K. pneumoniae ENSG303 are highly fibrous, compact, and nicely interlinked as compared to the biofilm developed by E. ludwigii ENSH201 and B. thuringiensis ENSW401. X-ray diffraction (XRD) results indicated that biofilm matrix produced by E. asburiae ENSD102, uncultured Vitreoscilla sp. ENSG301, and A. lwoffii ENSG302 are non-crystalline amorphous nature. Fourier transform infrared (FTIR) spectroscopy showed that proteins and polysaccharides are the main components of the biofilms. Congo red binding results suggested that all these bacteria produced proteinaceous curli fimbriae and cellulose-rich polysaccharide. Production of cellulose was also confirmed by Calcofluor binding- and spectrophotometric assays. E. asburiae ENSD102, Vitreoscilla sp. ENSG301, and A. lwoffii ENSG302 were tested for their abilities to form the biofilms exposure to 0 to 2000 mg/L of copper sulfate (for Cu), zinc sulfate (for Zn), lead nitrate (for Pb), nickel chloride (for Ni), and potassium dichromate (for Cr), several concentrations of these metals activated the biofilm formation. The polysaccharides is known to sequester the heavy metals thus, these bacteria might be applied to remove the heavy metals from wastewater.

Abstract
The use of anti-inflammatory natural products to treat inflammatory disorders for cancer prevention and therapy is an appealing area of interest in the last decades. Annona muricata L. is one of the many plant extracts that have been explored owing to their anti-inflammatory and anticancer effects. Different parts of A. muricata especially the leaves have been used for various ethnomedicinal purposes by traditional healers to treat several diseases including cancer, inflammation, diabetes, liver diseases, and abscesses. Some of these experience-based claims on the use of the plant have been transformed into evidence-based information by scientific investigations. The leaves of the plant have been extensively investigated for its diverse pharmacological aspects and found eminent for anti-inflammatory and anticancer properties. However, most studies were not on the bioactive isolates which were responsible for the activities but were based on crude extracts of the plant. In this comprehensive review, all significant findings from previous investigations till date on the leaves of A. muricata, specifically on their anti-inflammatory and anticancer activities have been compiled. The toxicology of the plant which has been shown to be due to the presence of neurotoxic annaceous acetogenins and benzyltetrahydro-isoquinoline alkaloids has also been updated to provide recent information on its safety aspects. The present knowledge of the plant has been critically assessed, aimed at providing direction toward improving its prospect as a source of potential anti-inflammatory and anticancer agents. The analysis will provide a new path for ensuring research on this plant to discover new agents to treat inflammatory diseases and cancer. Further in vitro and in vivo studies should be carried out to explore the molecular mechanisms underlying their anti-inflammatory responses in relation to anticancer activity and more detail toxicity study to ensure they are safe for human consumption. Sufficient preclinical data and safety data generated will allow clinical trials to be pursued on this plant and its bioactive compounds.

Abstract
Zerumbone (ZER), isolated mainly from the Zingiber zerumbet (Z. zerumbet) rhizomes was found to be effective against numerous inflammatory and immune disorders, however, the molecular and biochemical mechanisms underlying its anti-inflammatory and immunosuppressive properties have not been well studied. This study was carried out to examine the profound effects of ZER on inflammatory mediated MyD88-dependent NF-κB/MAPK/PI3K-Akt signaling pathways in LPS-stimulated U937 human macrophages. ZER significantly suppressed the up-regulation pro-inflammatory mediators, TNF-α, IL-1β, PGE2, and COX-2 protein in LPS-induced human macrophages. Moreover, ZER significantly downregulated the phosphorylation of NF-κB (p65), IκBα, and IKKα/β as well as restored the degradation of IκBα. ZER correspondingly showed remarkable attenuation of the expression of Akt, JNK, ERK, and p38 MAPKs phosphorylation in a concentration-dependent manner. ZER also diminished the expression of upstream signaling molecules TLR4 and MyD88, which are prerequisite for the NF-κB, MAPK and PI3K-Akt activation. Additionally, quantification of relative gene expression of TNF-α, IL-1β, and COX-2 indicated that, at a higher dose (50μM), ZER significantly downregulated the elevated mRNA transcription levels of the stated pro-inflammatory markers in LPS-stimulated U937 macrophages. The strong suppressive effects of ZER on the activation of inflammatory markers in the macrophages via MyD88-dependent NF-κB/MAPK/PI3K-Akt signaling pathways suggest that ZER can be a preventive and potent therapeutic candidate for the management of various inflammatory-mediated immune disorders.

Abstract
Studies of the impact of mental disorders on educational attainment are rare. Mental disorders, those beginning in childhood or adolescence may increase the risk of early drop out from education. The latter has been shown to have adverse life-course consequences on individuals such as greater demand on social welfare entitlements. A descriptive cross sectional study was carried out at the department of Psychiatry, Comilla Medical College, Comilla, Bangladesh. All cases were selected from patients attending at Comilla Medical College Hospital and Private Mental Health Facilities in Comilla City from March 2015 to February 2016. We found out the psychiatric disorders and socio-demographic status of patients with educational drop out over the early life course. A total of 50 dropout patients aged 10 to 30 years who fullfiled the enrolment criteria included in the study. Sociodemographic questionnaires, diagnostic information (DSM-5 and ICD-10) as well as an account of a various level of education were used as research instruments. The Frequency tables, summary tables and appropriate graphs were prepared to describe the population characteristics and study finding. The most of the psychiatric morbidity presents in male (62%) and age group of 18-24 years (54%). In this study, anxiety disorders was 8%, behaviour/ impulse control disorders was 8%, mood disorders was 16%, substance use disorders was 24%, schizophrenia spectrum disorders was 12% and composite psychiatric disorders was 32%. Among drop out patient's non- completion of primary education was 14%, non-completion of secondary education was 20%, non- completion of higher secondary education was 24%, not entry to tertiary education was 12% and non-completion of tertiary education was 30%. Among behaviour/impulse control disorders non-completion of primary education was 6%, substance use disorders non-completion of higher secondary education was 10%, mood disorder both non-completion of higher secondary education and non-completion of tertiary education were 6%. Among composite psychiatric disorders non-completion of secondary education, non-completion of higher secondary education and non-completion of tertiary education were 8%, 6% and 12% respectively. Onset of mental disorders and subsequent drop out from education was found in this study. Further multi-centered prospective and population-based studies should be designed to find out the exact situation.

Abstract
The immune system is complex and pervasive as it functions to prevent or limit infections in the human body. In a healthy organism, the immune system and the redox balance of immune cells maintain homeostasis within the body. The failure to maintain the balance may lead to impaired immune response and either over activity or abnormally low activity of the immune cells resulting in autoimmune or immune deficiency diseases. Compounds containing α,β-unsaturated carbonyl-based moieties are often reactive. The reactivity of these groups is responsible for their diverse pharmacological activities, and the most important and widely studied include the natural compounds curcumin, chalcone, and zerumbone. Numerous studies have revealed the mainly immunosuppressive and anti-inflammatory activities of the aforesaid compounds. This review highlights the specific immunosuppressive effects of these natural α,β-unsaturated carbonyl-based compounds, and their analogs and derivatives on different types of immune cells of the innate (granulocytes, monocytes, macrophages, and dendritic cells) and adaptive (T cells, B cells, and natural killer cells) immune systems. The inhibitory effects of these compounds have been comprehensively studied on neutrophils, monocytes and macrophages but their effects on T cells, B cells, natural killer cells, and dendritic cells have not been well investigated. It is of paramount importance to continue generating experimental data on the mechanisms of action of α,β-unsaturated carbonyl-based compounds on immune cells to provide useful information for ensuing research to discover new immunomodulating agents.

Abstract
BACKGROUND Zingiber zerumbet (L.) Roscoe ex Sm. (family, Zingiberaceae) is a potent medicinal herb widely known as shampoo ginger and its rhizome is used in numerous ethnomedicinal applications including antipyretic, anti-inflammatory, antibacterial, anti-diarrheal, antidiabetics, carminative, and diuretic. The aim of this review was to bring together all the scientific updates on the phytochemistry and pharmacological activities of this herb, including their toxicological studies, and critically analyzed the outcomes to provide directions for future research on the herb as potential source of bioactive metabolites for pharmaceutical and nutraceutical applications. METHODS A structured electronic search on worldwide accepted scientific databases (Web of Science, PubMed, Google Scholar, Science Direct, SciFinder, Wiley Online Library) was carried out to compile the relevant information. Some information was obtained from books and database on medicinal plants used in various countries. RESULTS About 60 metabolites, mainly polyphenols, and terpenoids have been isolated and identified. However, most of the reported pharmacological studies were based on crude extracts, and only a few of those isolated metabolites, particularly zerumbone have been investigated for biological and pharmacological activities. Many of the mechanistic studies to understand the pharmacological effects of the plant are limited by many considerations with regard to design, experimentation and interpretation. CONCLUSION The bioactive metabolites should be further investigated on their safety and more elaborate preclinical studies before clinical trials can be undertaken.

Abstract
Niemann-pick disease is a group of autosomal recessive disorder of lipid storage with progressive accumulation of sphingomyelin and other lipids in the lysosomes of various tissues. We are reporting a 21 year old male who had hepatosplenomegaly, cherry red macula and normal cognitive function. Bone marrow biopsy showed plenty of foam cells and sphingomyelinase level was low, thus conforming our diagnosis. Survival into adulthood and absence of gross neurological involvement suggests Niemann-Pick disease type B.

Abstract
Zinc plays a vital role in the immune status. Its deficiency affects host defense by reducing the number of circulating T cells and phagocytosis activity of other cells which ultimately impair cell mediated immunity. The cell-mediated immunity plays a major role in the causation of pulmonary tuberculosis. The present study was carried out to estimate serum zinc level in newly detected multidrug resistant tuberculosis (MDR-TB) in adult population. In this study total fifty (50) MDR-TB patients were enrolled conveniently from the in-patients departments of National Institute of Diseases of the Chest Hospital (NIDCH), Bangladesh. Serum zinc was estimated by atomic absorption spectrophotometry method from early morning fasting blood sample. Serum zinc level was assessed according to normal cut-off value 70-120 μgm/dl and 76% studied population were found lower than this value. The mean±SD serum zinc level was observed 60.40±8.91 μgm/dl. No associations were found between serum zinc level with age (p=0.11) and with sex (p=0.085) of the study population respectively. The low level of serum zinc in MDR-TB patients suggested impaired immune status of our study population.

Abstract
This case control study was done to ascertain the association between exposures to biomass cooking fuel smoke and pulmonary tuberculosis. Cases were all newly diagnosed pulmonary tuberculosis patients, randomly collected from the Hospital (DOTS centers) Registry from January 2012 to June 2012 from two Upazillas of Sirajganj district, Bangladesh. A home visitation program was done subsequently. Healthy controls were recruited from the neighbourhood of each case through a predefined procedure. Total 276 new pulmonary tuberculosis cases and 276 neighbourhood controls were enrolled. A semi-structured questionnaire containing demographic information, smoking habits, cooking place, kitchen condition, use of biomass fuel for cooking was used for interview. Crude (unadjusted) odd ratios and their corresponding 95% confidence limits for independent variables were determined by binary logistic regression. All significant variables were entered into a multivariate conditional logistic regression model and a final fitted model was determined by backward elimination methods. In univariate analysis, member of a nuclear family {Unadjusted odd ratio (Unadj. OR) 1.570, 95% CI 1.008-2.44)}, having non-formal education (Unadj. OR 2.739, 95% CI 1.219, 6.153) or primary (Unadj. OR 3.407, 95% CI 1.492, 7.782) to secondary level (Unadj. OR 2.392, 95% CI 1.032, 5.544) education, using cow dung (Unadj. OR 3.961, 95% CI 1.267, 12.376) and biomass fuel i.e. plant origin (Unadj. OR 3.382, 95% CI 1.087, 10.518) for cooking, past smoker (Unadj. OR 2.504, 95% CI 1.061, 5.910), using open oven (Unadj. OR 3.109, 95% CI 0.995, 9.716), having small kitchen area (Unadj. OR 0.99, 95% CI 0.989, 0.999) all were significantly associated with tuberculosis. When all significant variables were entered into a multivariate conditional logistic regression model nuclear family {Adjusted odd ratio (Adj OR) 1.808, 95% CI 1.127, 2.9)}, primary level education (Adj OR 2.86, 95% CI 1.23, 6.647) and non formal education (Adj OR 2.312, 95% CI 1.013, 5.276), biomass fuel (plant origin, Adj OR 3.497, 95% CI 1.059, 11.55), and cow dung (Adj OR 4.368, 95% CI 1.319, 14.464)) used in cooking and irregular smoker (who stop smoking at least 6 month back) (Adj OR 2.806, 95% CI 1.141, 6.901) were significantly associated with tuberculosis cases. From this study significant association have been found between exposure to combustion of biomass cooking fuel and tuberculosis.

Abstract
It is suggested in different studies that gender has a great impact on the distribution of risk factors of stroke. This study aims at determining the gender differences in risk factors of acute ischemic stroke among male and female patients. Data extracted for this study were taken from a case control study which was carried out in the departments of Neurology and Medicine of Dhaka Medical College Hospital (DMCH) and Shaheed Suhrawardy Medical College Hospital (ShSMCH) Dhaka from July 2009 to June 2011. We collected data of 125 patients with ischemic stroke and 129 healthy controls from the primary source. All secondary data were divided on the basis of gender. Among all male respondents 70 stroke patients were considered as case and 72 healthy respondents were considered as control and in female group 55 were stroke patients (case) and 57 were healthy control. Risk factors of stroke for male and female were evaluated separately. After multivariate analysis ever smoking (both present and ex smoker) (adj. OR 3.799, 95% CI 1.416, 10.19), diabetes mellitus (adj. OR 5.687, 95% CI 1.99, 16.26), hypertension (adj. OR 18.53, 95% CI 6.43, 53.4) and total cholesterol (adj. OR 1.017, 95% CI 1.01, 1.03) were found significant predictors for stroke in male whereas diabetes mellitus (adj. OR 6.989, 95% CI 1.54, 31.64), hypertension (adj. OR 17.85, 95% CI 5.1, 62.38), serum low density lipoprotein (LDL) (adj. OR 1.04, 95% CI 1.013, 1.07) and serum triglyceride (TG) (adj. OR 1.012, 95% CI 1.004, 1.02) were found significant in female. Besides taking the controlling measure for hypertension and diabetes mellitus, life style modification is an important factor to prevent stroke in both sexes.

Abstract
Heterostructures of two-dimensional materials can be vulnerable to thermal degradation due to structural and interfacial defects as well as thermal expansion mismatch, yet a systematic study does not exist in the literature. In this study, we investigate the degradation of freestanding WSe2-graphene heterostructures due to heat and charge flow by performing in situ experiments inside a transmission electron microscope. Experimental results show that purely thermal loading requires higher temperatures (>850 °C), about 150 °C higher than that under combined electrical and thermal loading. In both cases, selenium is the first element to decompose and migration of silicon atoms from the test structure to the freestanding specimen initiates rapid degradation through the formation of tungsten disilicide and silicon carbide. The role of the current flow is to enhance the migration of silicon from the sample holder and to knock-out the selenium atoms. The findings of this study provide fundamental insights into the degradation of WSe2-graphene heterostructures and inspire their application in electronics for use in harsh environments.

Abstract
Pancreatic carcinoma is a life threatening condition. Surgical resection is the only hope of cure. Advances in surgical technique have reduced the mortality rate. Nevertheless, operative complications related with morbidity still remains high. Two operation techniques in the treatment of periampullary and pancreatic head cancer: the Standard Whipple operation (SW) and Pylorus Preserving Pancreaticoduodenectomy (PPPD) are performed predominantly. This study was performed to compare the results of Pylorus Preserving Pancreaticoduodenectomy (PPPD) with that of the Standard Whipple's (SW) procedure. This prospective study was carried out in the Department of General Surgery, BSMMU in two years duration. All admitted patient's with periampullary carcinoma and carcinoma of the head of the pancreas were included and randomized for a SW or a PPPD resection. Data regarding patients demographics, preoperative assessment, intraoperative and postoperative findings were collected and analyzed. Less blood loss (2.67±0.65 units in Group I and 2.88±0.64 units in Group II), fewer need of blood transfusions and shorter hospital stay in the PPPD group were observed. Gastrointestinal leakage was similar in both groups of patients (1:1). One pancreatic fistula (8.3% in Group I) was observed in PPPD group and one intra-abdominal abscess developed in Standard Whipple's procedure (00.0% in Group I and 12.5% in Group II). Bile leakage was higher in standard Whipple procedure (8.3% in Group I and 37.5% in Group II). Morbidity was more or less similar in both groups (58.0% in Group I and 50.0% in Group II) but one patient (12.5% in Group II) died in standard Whipple's resection. PPPD procedure is more effective treatment for periampullary carcinoma and cancer of the pancreatic head region than the standard Whipple's operation.

Abstract
The clinical evidence of neurological menifestations associated with asphyxia is described as hypoxic ischaemic encephalopathy (HIE). A variety of metabolic problems are present in asphyxiated newborns including hypoglycemia, hypocalcemia, hypomagnesemia and others metabolic abnormalities. Some of these biochemical disturbances may trigger seizure or potentiate further brain damage. This cross sectional case-control study was done in Mymensingh Medical College Hospital, to identify the association of hypoglycemia, hypocalcemia, hypomagnesemia in neonates with perinatal asphyxia. Study period was six months. Sample size was 60. Among total sample 30 term asphyxiated newborns of <24 hours age were case and equal number term healthy newborns <24 hours age were control. The main clinical presentations were delayed cry after birth along with respiratory distress, convulsion and absence of cry in asphyxiated newborns. Major physical findings were cyanosis, convulsion and tachypnoea in asphyxiated group. The mean value of serum calcium level was significantly lower in asphyxiated newborns (7.37 ± 0.10mg/dl) than control value (8.04±0.09mg/dl). Hypocalcemia was found among 23.33% babies in case group. On the contrary, hypocalcemia was found in single baby among control group. The mean value of serum magnesium was significantly lower in asphyxiated newborns (1.83 ± 0.04mg/dl) than control value (1.96 ± 0.05mg/dl). Hypomagnesemia was found among 3(10%) newborns but none was found among control group. Hypoglycemia was found in 7(23.33%) cases though the mean value of blood glucose was higher in case group (5.72 ± 0.62mmol/l) than control group (4.87 ± 0.15mmol/l) difference was not statistically significant. Combined hypoglycemia, hypocalcemia and hypomagnesemia were found in 1(3.33%) case; combined hypoglycemia and hypocalcemia were found in 2(6.67%) cases; and combined hypocalcemia and hypomagnesemia were found in 1(3.33%) case. During the study period, 3(10.0%) cases were expired but no death occurred among control group. This study shows isolated or combined hypoglycemia, hypocalcemia, hypomagnesemia are frequently found in newborns with perinatal asphyxia. So, it is necessary to monitor blood glucose, serum calcium and also serum magnesium among asphyxiated newborns for proper management.

Abstract
This cross sectional descriptive study was done by using nonprobability sampling technique and performed by examining 63 (sixty three) cerebellum. Out of them 40 postmortem human cerebellum collected from Bangladeshi cadavers of both sexes (male 25 and female 15) age ranging from 5 to 60 years and 23 cerebellums from caesarian section of intrauterine death cases of both sexes (male 14 and female 9) age ranging from 34 to 41 weeks of gestation. Specimens were collected from dead bodies autopsied on different dates from April' 2009 to September' 2009 at the autopsy laboratory of department of Forensic Medicine and prenatal cases from Gynaecology and Obstetrics Department of Mymensingh Medical College, Mymensingh. The collected specimens were grouped into three age groups like Group A (28 to 42 weeks of gestation), Group B (5 to 30 years) and Group C (31 to 60 years) and, two sex groups (male and female) and two sides (right and left). A transverse section was made at the level of horizontal fissure, and length and breadth of dentate nucleus were measured by divider and scale. The mean (±SD) length and breadth of dentate nucleus was 8.619±2.995mm and 14.770±3.604mm respectively and it was observed that length and breadth of dentate nucleus increased with age upto certain level then slightly decreased in the late age Group C. In this study, differences of the mean length of dentate nucleus on both right and left sides were statistically moderately significant between age Groups A&B. The differences of mean breadth of dentate nucleus on both right and left side were statistically highly significant between age Groups A&B and moderately significant between age Groups A&C on right side and only significant on left side. The differences between male & female were statistically insignificant in length and breadth of dentate nucleus.

Abstract
Increasing prevalence of diabetes and its complications in the developing communities would pose a threat in respect to their existing health care service. An increased incidence of atherosclerosis in insulin-dependent diabetic patients has long been recognized. Hyperlipidaemia, a common finding in these patients, may be one of the contributing factors. The objective of our study is to find out the patterns of dyslipidaemia among the Bangladeshi patients with type-2 diabetes mellitus presented with acute coronary syndrome. This study was conducted in the department of cardiology of BIRDEM and Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh during the period of January 2009 to December 2009. A total of 100 patients were included in this study, according to the inclusion and exclusion criteria. Diabetes Mellitus and Acute Coronary Syndrome was diagnosed according to the guideline of American Diabetic Association and American College of Cardiology respectively. Among the respondents Mean±SD of fasting blood sugar and 2 hours ABF were 9.23±3.6mmol/L and 12.61±8.52mmol/L respectively. Mean±SD of HbA1C of the respondents was 7.23±2.12. Total cholesterol level <150mg/dl, 150-200mg/dl and >200mg/dl were 27.0%, 42.0% and 31.0% respectively. HDL cholesterol <40mg/dl and >40mg/dl were 76.0% and 24.0% respectively. LDL cholesterol <150mg/dl and >150mg/dl were 43.0% and 57.0% respectively. TG within 40 to 160mg/dl and >160mg/dl were 73.0% and 27.0% respectively, Mean±SD of Total Cholesterol, HDL Cholesterol, LDL Cholesterol and Triglyceride were 162.43±38.62, 37.41±8.59, 137.43±22.73 and 156.43±41.92mg/dl respectively.

Abstract
Placenta is the mirror of maternal and fetal status; it reflects the changes due to complication in pregnancy of mother. Numerous common and uncommon findings of the placenta, umbilical cord and membranes are associated with abnormal fetal development and perinatal morbidity. So, the examination of the placenta can yield information that may be important in the immediate and later management of mother and newborn. This information may also be essential for protecting the attending physician in the event of an adverse maternal or fetal outcome. This cross sectional descriptive study was carried out to determine the incidence of different types of placenta depending on attachment site and branching pattern of arteries of umbilical cord in Bangladeshi Women. To achieve this aim sixty placenta with umbilical cord were collected. Placenta was from 28 weeks to 42 weeks gestational age of normal pregnancy during normal labour at gynaecology and obstetric department of Mymensingh Medical College Hospital. After preservation in 10% formol saline, study was done in the Department of Anatomy of Mymensingh Medical College. In the present study, incidence of different types of placenta depending on attachment site of umbilical cord was 50% Central, 46% Paracentral and 18% Marginal in type. In this study it was also observed that 58% placenta were Disperse in type and 42% were Magistral in type depending on the distribution of umbilical arteries. Observed findings of this study were compared with those of Western and Bangladeshi researchers.

Abstract
Febrile seizures are the most common type of seizure among children that can be prevented by using prophylactic drugs like Clobazam and Diazepam. The present prospective study was conducted in the Department of Pediatrics, Mymensingh Medical College Hospital and Community Based Medical College Hospital, Bangladesh over a period of 1 year from July 2012 to June 2013 to compare the effectiveness of intermittent Clobazam versus Diazepam therapy in preventing the recurrence of febrile seizures and assessed adverse effects of each drug. A total of 65 patients (32 children administered Clobazam and rest 33 children received Diazepam) of simple and complex febrile seizures aged 6 months to 5 years of both sexes were the study population. Data were collected by interview of the patients, clinical examination and laboratory investigations using the research instrument. Data were analyzed by using Chi-square (χ2) Test, Student's 't' Test and Fisher's Exact Test. For all analytical tests, the level of significance was set at 0.05 and p<0.05 was considered significant. The proportion of patients was higher between age 12-36 months and male was predominant in the both Clobazam and Diazepam groups. Over 31% of patients in Clobazam group who experienced episode of fever within 3 months, 40.6% within 6 months and 9.4% within 9 months compared to 36.4% in Diazepam group within 3 months, 45.5% within 6 months & 12.1% within 9 months after discharge from the hospital. Three (9.4%) patients in Clobazam group and 7(21.3%) in Diazepam group who experienced febrile convulsion during the follow up period. From the data adverse effects within 3 and 6 months experienced by the patient's drowsiness, sedation and ataxia were higher in Diazepam group than those in Clobazam group. However, within 9 months lethargy and irritability were somewhat higher in Clobazam group than those in Diazepam group. The mean duration of hospitalization was significantly higher in Diazepam group compared to Clobazam group (6.0±1.0 vs. 4.6±0.08 days, P<0.001). Seven (21.2%) out of 33 children with febrile seizures in Diazepam group had a history of recurrent seizures, whereas 3(9.4%) of 32 children in the Clobazam group. The risks of recurrent febrile seizure in the Diazepam group was 2.6 times greater compared to those in the Clobazam group (P=0.186). The result indicates that Clobazam is safe, efficacious, requires less frequent dosing and has less adverse effects such as drowsiness, sedation, ataxia and irritability as compared to Diazepam. So, Clobazam may be an alternative to Diazepam given intermittently for prevention of recurrent febrile seizures.
