Association of Serum Vitamin D level with Asthenozoospermic Male

Although vitamin D deficiency is one of the most common health problems throughout the world, conflicting information exists on the potential association between serum vitamin D levels and semen quality. Currently available data identifies that vitamin D has a vital role in reproductive process as it affects sperm motility. This study was done with the rationality to evaluate the association between serum vitamin D levels with asthenozoospermic males. This cross-sectional analytic study was conducted on 314 men who attended the Department of Reproductive Endocrinology and Infertility, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh July 2018 to June 2019. Considering the inclusion and exclusion criteria all participants were categorized into two groups; Group I included 157 asthenozoospermic male and Group II included 157 normozoospermic male according to World Health Organization 'strict' criteria 2010. Participants completed the questionnaires after they had agreed on a informed consent. Blood and semen samples were obtained for assessment and all data were adjusted for age, body mass index (BMI), total motility and progressive motility. Vitamin D levels were classified according to the Endocrine Society guideline. Statistical analyses were carried out by using the Statistical Package for Social Sciences version 22.0 for Windows (SPSS Inc., Chicago, Illinois, USA). The results showed that the mean vitamin D level was 16.63±5.54ng/ml in asthenozoospermic group and 19.83±5.33ng/ml in normozoospermic group. The mean vitamin D level was significantly (p<0.05) lower in asthenozoospermic group. It was noticed that 86.6% patients had vitamin D deficiency (≤20ng/ml) in asthenozoospermic group compared to 56.7% in the normozoospermic group. The study found that low vitamin D was associated with a fivefold increased risk of developing asthenozoospermia at 95% CI (2.74-8.99). Moreover, there was a positive significant correlation (r=0.285; p<0.001) between serum vitamin D level with total motility and progressive motility (r=0.232; p<0.001). Hence, the study suggests a significant association between asthenozoospermia and low vitamin D levels. However, clinical trials are warranted to further reinforce the findings.

Bark extract of Chaetocarpus castanocarpus (Roxb.) exhibits potent sedative, anxiolytic, and antidepressant effects through an in vivo approach in Swiss albino mice

OBJECTIVE

Standard phytochemical investigations were performed to identify the secondary metabolites in the methanol extract of Chaetocarpus castanocarpus bark (MECC) and investigate the neuropharmacological potential of MECC in Swiss albino mice.

MATERIALS AND METHODS

Swiss albino mice were used in the forced swimming test (FST) and tail suspension test (TST) to evaluate the antidepressant effect of MECC. Also, the hole board test (HBT) and elevated plus maze (EPM) were conducted to examine anxiolytic activities. In contrast, the open field test (OFT) and hole cross test (HCT) were employed to evaluate sleeping disorders.

RESULTS

Alkaloids, glycosides, flavonoids, terpenoids, coumarins, and tannins are only a few secondary metabolites identified in MECC by qualitative and quantitative phytochemical investigations. The oral administration of MECC considerably shortened the immobility duration during FST and TST. Encouraging dose-dependent anxiolytic effects were also observed in all relevant experiments compared to the control. Additionally, during the OFT and HCT assessment, a noteworthy decline in the locomotor activities of the experimental animals was observed.

CONCLUSIONS

The results of this investigation suggest that the Chaetocarpus castanocarpus bark is a possible source of therapeutic candidates for treating neurological disorders.

Rainwater harvesting for agriculture development using multi-influence factor and fuzzy overlay techniques

Rainwater harvesting (RWH) is an essential technique for enhancing agricultural development, particularly in regions facing water scarcity or unreliable rainfall patterns. Water shortage, however, is one of the key causes of low crop production especially in mountainous regions like the Khyber Pakhtunkhwa province where most rainwater is lost by runoff. Therefore, rainwater harvesting could be a suitable to make better use of runoff and increase crop production. The study focuses on selecting suitable rainwater harvesting sites in District Karak to enhance agriculture by utilizing multi-influence factor (MIF) and fuzzy overlay techniques. We considered seven factors, i.e., land use land cover (LULC), slope, geology, soil, rainfall, lineament, drainage density, to create a ranking system to understand its application in site selection analysis. The results were combined into one overlay process to produce a rainwater harvesting suitability map. The weighted overlay analysis of the MIF model results reveals that 167.96 km2 area has a very high potential for rainwater harvesting, 874.17 km2 has a high potential, 1182.92 km2 has a moderate and 354.50 km2 has a poor potential for rainwater harvesting. The fuzzy overlay analysis revealed that 257.53 km2 has a very high potential for rainwater harvesting, 896.56 km2 area is classified as high, 1018.30 km2 moderate, and 407.7 km2 has poor potential for rainwater harvesting. The findings of this research work will help the policymakers and decision-makers construct various rainwater harvesting structures in the study area to overcome the water shortage problems.

Unveiling the Anthelminthic Potential of Merremia vitifolia Stem through in Vitro and in Silico Approach

This study aimed to assess the anthelmintic activity of methanol extracts from Merremia vitifolia stems using a combination approach encompassing experimental, in vitro, and in silico evaluations. Despite the well-recognized pharmacological properties of M. vitifolia, its potential as an anthelmintic agent remained unexplored. This plant's anthelmintic potential was assessed on adult earthworms (Pheretima posthuma), revealing a dose-dependent reduction in spontaneous motility leading to paralysis and eventual mortality. The most effective dose of M. vitifolia (200 mg/ml) for anthelmintic effects on Pheretima posthuma was identified. Complementary in silico investigations were also conducted, employing Autodock PyRx 0.8 for docking studies of reported M. vitifolia compounds. Notably, quercetin emerged as a promising candidate with superior binding energies against β-tubulin (-8.3 Kcal/mol). Moreover, this comprehensive research underlines the anthelmintic potential of Merremia vitifolia stem extract and highlights quercetin as a noteworthy compound for further investigation in the quest for novel anthelmintic agents.

Evaluation of Fecal Pancreatic Elastase-1 as a Measure of Pancreatic Exocrine Function in Children with Pancreatitis

Pancreatic exocrine insufficiency occurs as a clinical consequence of chronic pancreatitis leading to fat maldigestion, malabsorption and malnutrition. Fecal elastase-1 is a laboratory-based test used for the diagnosis or exclusion of pancreatic exocrine insufficiency. The aim of the study was to observe the value of fecal elastase-1 in children with pancreatitis as an indicator of pancreatic exocrine insufficiency. This was a cross-sectional descriptive study conducted from January 2017 through June 2018. Thirty children with pain abdomen as control and 36 patients with pancreatitis as cases were included. An ELISA technique which recognizes human pancreatic elastase-1 from spot stool sample was employed for the test. Fecal elastase-1 activity in spot stool samples in acute pancreatitis (AP) ranged from 198.2-500μg/g with a mean of 342.1±136.4μg/g, acute recurrent pancreatitis (ARP) ranged from 15-500μg/g with a mean of 332.8±194.5μg/g and chronic pancreatitis (CP) ranged from 15-492.8μg/g with a mean of 222.2±197.1μg/g was obtained. In controls, fecal elastase-1 ranged from 28.4-500μg/g with a mean of 398.8±114.9μg/g. Disease severity was classified as mild to moderate pancreatic insufficiency (fecal elastase-1 100 to 200μg/g stool) was found in AP (14.3%) and CP (6.7%) cases. The severe pancreatic insufficiency (fecal elastase-1<100μg/g stool) was observed in ARP (28.6%) and CP (46.7%) cases. Malnutrition was observed in severe pancreatic insufficiency cases. This study result showed that fecal elastase-1 can be used as a measure of pancreatic exocrine function in children with pancreatitis.

Association between Serum Vitamin D and Metabolic Syndrome in Women with Polycystic Ovary Syndrome

Vitamin D deficiency (VDD) is common in women with and without polycystic ovary syndrome (PCOS) and may be associated with metabolic and endocrine disorders in PCOS. Aim of the study was to evaluate the association between serum vitamin D level and metabolic syndrome (MS) in PCOS. This cross-sectional study was conducted in PCOS clinic of infertility outpatient department of the department of Reproductive Endocrinology and Infertility at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2018 to June 2019. A total of 170 diagnosed patients with PCOS of aging 20 to 40 years were included in this study. Out of which 85 patients with PCOS MS and rest 85 patients without PCOS MS were considered as Group I and Group II respectively. Serum vitamin D was measured using a chemiluminescent microparticle immunoassay (CMIA). Almost two third (72.9%) populations had vitamin D moderate deficiency (10-20ng/ml) in Group I and 46(54.1%) in Group II. The mean vitamin D was 13.97±4.53ng/ml in Group I 16.02±6.62ng/ml in Group II. There were significant negative correlation found between vitamin D level with weight (r = -0.169; p=0.028), waist circumference (r = -0.208; p=0.007), Waist/Hip ratio (r = -0.205; p=0.007) and diastolic blood pressure (r = -0.187; p=0.014). In binary logistic regression analysis diastolic blood pressure (OR=1.04, 95% CI 0.89-1.29), fasting Glucose (OR=1.09, 95% CI 0.89 - 1.42), HDL (OR=1.11, 95% CI 1.05 - 1.17) and Vitamin D (OR=1.37, 95% CI 1.01 - 1.82) were significant risk factors of metabolic syndrome of the study patients. Vitamin D level was lower in PCOS subjects having MS and higher frequency of body weight, vitamin D deficiency was observed in them compared to the non-MS group. Waist: hip ratio, waist circumference and diastolic blood pressure were the negatively correlated with of vitamin D in the study subjects.

Cinematic reflectometry using QIKR, the quite intense kinetics reflectometer

The Quite Intense Kinetics Reflectometer (QIKR) will be a general-purpose, horizontal-sample-surface neutron reflectometer. Reflectometers measure the proportion of an incident probe beam reflected from a surface as a function of wavevector (momentum) transfer to infer the distribution and composition of matter near an interface. The unique scattering properties of neutrons make this technique especially useful in the study of soft matter, biomaterials, and materials used in energy storage. Exploiting the increased brilliance of the Spallation Neutron Source Second Target Station, QIKR will collect specular and off-specular reflectivity data faster than the best existing such machines. It will often be possible to collect complete specular reflectivity curves using a single instrument setting, enabling "cinematic" operation, wherein the user turns on the instrument and "films" the sample. Samples in time-dependent environments (e.g., temperature, electrochemical, or undergoing chemical alteration) will be observed in real time, in favorable cases with frame rates as fast as 1 Hz. Cinematic data acquisition promises to make time-dependent measurements routine, with time resolution specified during post-experiment data analysis. This capability will be deployed to observe such processes as in situ polymer diffusion, battery electrode charge-discharge cycles, hysteresis loops, and membrane protein insertion into lipid layers.

Transmission of SARS-CoV-2 Delta variant from an infected aircrew member on a short-haul domestic flight, Australia 2021

In June 2021, when COVID-19 incidence in Australia was low, a COVID-19 (Delta variant) cluster occurred on an 81-minute domestic flight, with an aircrew member as the likely source. Outbreak investigation demonstrated that SARS-CoV-2 may be transmitted during short-haul flights and that mask use protected against infection.

Neuropharmacological Effects of Chassalia curviflora (Rubiaceae) Leaves in Swiss Albino Mice Model

The current study aimed to investigate the neuropharmacological properties of ethanol, acetone, and ethyl acetate leaf extracts of Chassalia curviflora (C. curviflora) in mouse models. The neuropharmacological properties of this plant were studied on Swiss albino mice at dosages of 50, 100, and 200 mg/kg body weight in thiopental sodium-induced sleeping time test, and at dosages of 100 and 200 mg/kg body weight in other tests. The extracts caused a marked reduction in the initiation and sleep length (P<0.05) in studies on thiopental sodium-induced sleeping time at dosages of 100 and 200 mg/kg and a significant decrease (P<0.05) was found in terms of unconstrained locomotor and explorative activities in both hole crossing and open field tests at dosages of 100 and 200 mg/kg. Furthermore, the extracts increased sleeping time with a dosage-dependent onset of action. The hole-board test extracts also reduced the number of head dips at dosages of 100 and 200 mg/kg (P<0.05). It was found in this study that C. curviflora had the best neuropharmacological properties at a dosage of 200 ml/kg. Our findings also showed that all of the extracts from C. curviflora were experimentally active in an in vivo model. The study results suggested that the leaves had strong anti-depressant and hypnotic CNS properties that might be exploited for neuropharmacological adjuvant therapy in conventional medicine. However, pharmacological studies are warranted to explore the active substances and the mode of action.

Evaluation of Short Term Outcome of Stapled Transanal Rectal Resection (STARR) for ODS (Obstructed Defecation Syndrome) by Comparing Pre and Post-operative ODS Score

Obstructed defecation syndrome (ODS) is a common anorectal problem and it can be corrected by various surgical approaches but most of these have high recurrence and complication rates. Antonio Longo introduced Stapled transanal rectal resection (STARR) in 2003 as a minimally invasive transanal operation for correction ODS associated with rectocele and or rectal intussusception. This study was designed to assess the short term outcome of Stapled Transanal Rectal Resection (STARR) as a surgical treatment of Obstructed Defecation Syndrome (ODS). This is a quasi experimental study which was carried out in the department of Colorectal Surgery, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from May 2016 to June 2017. Seventeen (17) patients were included in the study. Patients with obstructed defecation syndrome and rectocele and or rectal intussusception admitted in the department of Colorectal Surgery were enrolled in the study as per inclusion and exclusion criteria. History, clinical examination, Proctoscopy, Colonoscopy and MR Defecography was done for evaluation of the patients. During evaluation preoperative Longo's ODS score of every patient also determined and compared with postoperative ODS score. The patient was followed up regularly at one, three and six months after each operation. The ODS score in 82.35% patients improved significantly. The postoperative score was high (13-15) only in 02(11.8%) patients probably due to presence of physiological factors. Post-operative defecatory urgency was developed in only 02(11.76%) patients. Major postoperative complication like hemorrhage or rectovaginal fistula did not develop in any patient. STARR is an effective, less invasive and simple procedure for the treatment of ODS with rectocele and/or rectal intussusception without major morbidity but other physiological causes of ODS should exclude preoperatively because its presence makes the surgical intervention fruitless.

Pattern of Tubercular Uveitis in Active Pulmonary Tuberculosis

Ocular tuberculosis is an extra-pulmonary form of systemic Tuberculosis (TB). It is rarely found concomitant with active pulmonary tuberculosis (PTB). The aim of this prospective observational study was to evaluate the pattern of tubercular uveitis (TBU) in the patients with active PTB who attended in our Uvea clinic at NIO&H from July 2018 to December 2020. Active PTB patients who had uveitis consistent with TBU and TBU patients who were confirmed as active lung lesion were included in the study. Chest X-ray, TST, IGRA (QuantiFERON-TB Gold Test), RT PCR of aqueous fluid for tubercular bacillus, Gene Xpert TB test of sputum were done to confirm the diagnosis of ocular and primary TB. If the induration is 15 mm of TST was considered patient in this study. Among 33 patients of active PTB, 4 had TBU (12.12%). Among 48 patients of TBU, 5 had active PTB (10.41%). 13 eyes of 9 patients were affected. Mean age at presentation was 41.8 years. There were anterior uveitis in 23.00% eyes, posterior uveitis in 69% eyes and panuveitis in 7.00% eyes. Choroidal granuloma was the most common presentation of posterior uveitis (46.00%). There were more than 4 times chance to develop choroidal granuloma in patients with active PTB than extrapulmonary TB (Χ²=4.53, <0.05), TBU patients with choroidal granuloma should be evaluated meticulously for active PTB and active PTB patients should be evaluated routinely by ophthalmologist for the search of TBU.

237 Antibiotic Prophylaxis of Precision Point Prostate Biopsy Under LA: Changed Practice in a District General Hospital

Aim

More than 4 million prostate biopsies are performed worldwide each year (1). Out of three different techniques (Template, transperineal, TRUS), Transperineal precision point biopsy under local anaesthesia is the latest and reported to have fewer infectious complications (2). UTI, Urosepsis, septicaemia are some well-known infectious complications following prostate biopsies. Therefore, the Canadian Urological Association recommended the use of broad-based Gram-negative antibiotic prophylaxis 30 to 60 minutes before the procedure and continued for 2 to 3 days in their guideline (3). Our aim was to compare the outcome of two different antibiotic prophylaxis regimens.

Method

In our study to assess the outcome of single-dose prophylaxis compared to regular dose, we collected retrospective data of 119 patients who had undergone precision point biopsy in our hospital.

Results

Among 119 patients, 52 (43.69%) were given 3 days of oral antibiotic followed by preprocedural dose and 67 (56.31%) were given just a single dose before the procedure. None of these patients from both groups were readmitted with any infectious complication post-procedure. 1 patient from the second group (single dose) was admitted with urinary retention but no increased inflammatory markers were found.

Conclusions

TRUS biopsy breeches the rectal mucosa and carries higher chances of post-biopsy infection so requires antibiotic prophylaxis. Single-dose antibiotic prophylaxis is recommended option for transperineal biopsies as the infection rate is lower. Our study shows the same outcome for single-dose and 3-day regimens for transperineal precision point prostate biopsy. Moreover, the use of single dose will significantly reduce medicine costs and antibiotic resistance to improve patient compliance.

Improved childhood immunization coverage using the World Health Organization's Tailoring Immunization Programmes guide (TIP) in a regional centre in Australia

In 2017 the World Health Organization's Tailoring Immunization Programmes guide (TIP) was used to identify pockets of low immunization coverage in Australia. The regional centre of Maitland had high numbers and rates of children who were overdue for scheduled vaccinations (2016, n = 344, 37.7%). Families were not opposed to immunization but had conflicting priorities or experienced service access barriers. A tailored strategy was developed including friendly, personalised reminders, outreach appointments and home visiting for those families most in need. Research translation was not quick and easy. A process evaluation identified areas where more support was needed to advance the strategy. Coverage rates have increased from 62.3% (2016) to 86.2% (2020). The number of overdue children has decreased even during COVID-19 restrictions when health services expected families would avoid primary care services. The TIP approach is valuable for improving childhood immunization coverage and is being utilised in other communities with low coverage.

Menstrual Hygiene Practice among Rural Adolescent School Girls: An Intervention Study

Menstruation, an essential part of the reproductive cycle, is experienced by all adolescent girls. Poor menstrual hygiene is associated with serious ill-health and drop-out from school. An intervention study was carried out to evaluate the outcome of health education on menstrual hygiene practice among randomly selected 45 adolescent girls attending in a purposively selected Shomospur Girls' High School, Khoksha at Kushtia district in 2018. Data were collected before and after intervention by pre-tested, semi-structured interview schedule with a view to explore the practice during menstruation. Majority 23(51.11%) subjects were between 10 to 14 years of age with a mean of 14.42±1.03 years. Mean age at menarche was 12.38±1.15 years. During menstrual period, adolescent girls used to refrain from performing daily household chores (34), skip from attending school (26), stay alone (26) and avoid to mix with others (25). Over two-thirds 31(68.89%) girls forbade nutritious foods like fish, meat, egg and tamarinds. As many as 39(86.67%) girls used to clean their genitalia, and everybody used to have regular bath and washing hands after changing menstrual absorbent. Generally, most of the girls (39, 86.67%) accustomed to use the reusable absorbent. Nearly one third 15(33.33%) girls used to dry the reusable absorbent in room corner, while 5(11.11) in shaded area and 3(6.67%) in the toilet. A considerable number of girls (12) stored the reusable materials in room corner and under the bed. At least 27(60.00%) girls did not use to change menstrual absorbent at school. While after intervention, none of the girls hesitated to attend others and felt safe to perform daily household chores. Moreover, they were confident to attend school and need not to stay alone during menstruation. Cent percent girls practiced to have food containing iron, vitamin C, and drank plenty of water. Warm water with soap and/or detergent was used for cleaning sanitary cloths. An overwhelming number 42(93.33%) of girls used to dry reusable materials in sunlight with a statistically significant difference (p<0.05). Change of behaviour as to frequency of changing sanitary pad (p<0.05) and methods of disposal of sanitary materials was revealed. It can be concluded that imparting knowledge to adolescent girls is effective to keep away from harmful social behaviours, food intake practice and use of sanitary napkin, replace of menstrual absorbent at regular interval and cleaning and storage of reusable sanitary materials with their hygienic disposal.

1214 A Combined Approach to Prioritise Patients for Colonoscopy

Aim

Correlating colonoscopy finding with presenting features to assess the diagnostic yield of different symptoms.

Method

We looked at findings of 100 patients retrospectively who had colonoscopy in Dhaka Medical College Hospital, Bangladesh during first peak of COVID (August 2020 to December 2020). We reviewed NICE guideline for high-risk symptoms and NHS guideline for prioritisation of colonoscopy patients.

Results

100 cases were reviewed, 67% were male among the patients, average age was 42.11 (4 – 75 years). 47 were found to have significant pathology. Findings included colorectal malignancy (28%), Polyp (9%), IBD (6%), tuberculosis (2%) etc. PR bleed had highest diagnostic yield (21.27%), followed by abdominal lump (17.02%) and lower abdominal pain (14.89%). Weight loss showed lowest diagnostic yield (4.25%). 28% colonoscopy findings were normal. Patients were chosen based on clinical assessments and imaging results, as stool biochemical marker tests (FIT test, faecal calprotectin) are not available in DMCH.

Conclusions

Being an aerosol generating procedure which has a considerable amount of risk of transmitting COVID infection from patient to clinician or vice versa, it is important to triage patients with lower GI symptoms for colonoscopy. In a developing country like Bangladesh, it is essential to make the most reasonable use of limited resources. Symptoms-based triaging systems are poor predictors of clinically significant disease on colonoscopy. Therefore, a more holistic and novel approach needs to be studied and formulated using a combination of symptoms, blood, and stool biomarkers in order to reduce the need for a ‘negative’ colonoscopy and avoid unnecessary risks.

Nanoparticles of resveratrol attenuates oxidative stress and inflammation after ischemic stroke in rats

Resveratrol is a nutraceutical compound that has exciting pharmacological potential in different diseases, including stroke. Due to its low bioavailability, the efficacy of resveratrol is minimal. Hence, the present study is aimed to synthesize and characterize nanoparticles of resveratrol (NR) followed by evaluating the neuroprotective role and elucidate the mechanism of NR in a rat model of middle cerebral artery occlusion (MCAO). Male Wistar rats (280-300 g) were pretreated with various doses (125 µg, 250 µg, and NR 500 µg; once daily, i.p.) of NR or vehicle (nanostructured lipid carriers) for 10 days. MCAO was performed for 2 h followed by reperfusion of 22 h. After 24 h of MCAO, animals were tested for the neurological outcome and were sacrificed for the analysis of infarct volume, oxidative, inflammatory, and apoptotic markers. NR-treated rats showed a substantial reduction in infarction compared to saline controls in parallel with improved motor and cognitive function. Further, NR pretreatment ameliorated oxidative stress markers and attenuated activities of antioxidant enzymes and Na+ K+ ATPase. The enhanced activities of caspases -3 and -9 and cytokines: interleukin-1β, and -6, and tumor necrosis factor-ɑ) in the MCAO group were significantly protected with the treatment of 500 µg of NR. Taken together, these data indicate that inhibition by NR has therapeutic potential in the ischemic stroke model. Further investigations into the therapeutic efficacy and post-treatment protocols are needed to confirm whether NR treatment could be a promising candidate for a stroke.

Preoperative Analysis of CA-I25 and its Relation with Histopathological Study in Ovarian Tumours

Ovarian cancer (OC) is the seventh most common cancer among women in the world. Epithelial OC is the most predominant pathological subtype, with five major histotype. All five subtypes that differ in origination, pathogenesis, molecular alterations, risk factors and prognosis. The clinical presentations of ovarian tumors are variable and not specific. Most of the malignant ovarian tumor seeks medical advice at advanced stage of the disease. At that stage no effective treatment could be possible. There are several researches are going on developing a screening test for ovarian cancer. But there hasn't been much success yet. Clinical examination such as complete pelvic examination together with two investigations is used most often to screen the ovarian cancer. These investigations are transvaginal ultrasound (TVUS) and the blood test CA-125. The measurement of CA-125 level usually in combination with other modalities like bimanual pelvic examination, transvaginal ultrasonography is the proposed modality of early detection of ovarian cancer. The most promising application of this tumor marker is the screening. Therefore this cross sectional and observational study was conducted to observe the relationship of histopathological diagnosis and clinical features with serum CA-125 levels. Study conducted from January 2017 to December 2017 at Sir Salimullah Medical College& Mitford Hospital, Dhaka, Bangladesh. All admitted Gynecological patients having ovarian tumors during study period were included purposively for this study. Sample size was 50. Clinical features and preoperative findings of CA-125 level of these 50 patients were collected. Finally histopathological reports were accumulated after operative treatment. Gastrointestinal & constitutional complain, gynecologic mass and pain in abdomen were the selected symptoms. CA-125 levels were evaluated in relation with histopathological findings. The different findings were correlated with those of studies done at home and abroad. Mean age of the study population was (Mean±SD) 34.25±14.65. Histological findings among the study population showed that benign tumors were 72% (n=36) and malignant tumors were 28% (n=14). In case of benign ovarian tumors among 36 women, 94.4% (n=34) of them showed CA 125 level <35U/ml, other 5.6% (n=2) showed more than normal (>35U/ml) but range was 35-65U/ml. While 14 of the study population having histopathologically proven malignant ovarian tumor, showed the tumor marker level >35U/ml among 71.4% (n=10) and 28.6% (n=4) showed tumor marker <35U/ml. This finding was statistically significant (p=0.001). Histopathological findings revealed that there were significant increases in CA-125 levels in women with malignant serous histotype of serous cyst adenocarcinoma where range of CA-125 level were 2018.88 to 4249.63U/ml. Constitutional symptoms such as weight loss, loss of appetite, symptoms of mass effect such as urinary retention and rapidly progressing tumor were the symptoms of malignant ovarian tumors. Preoperative elevated level of CA-125 is the differentiating points of malignant serous histotype from benign ovarian tumors. This study will put forward some clues about the clinical diagnosis of ovarian tumor which may be utilized for making investigation and management plan. Also it will help for making prompt decision during pre-operative and per-operative procedures.

Renoprotective effects of cinnamon oil against APAP-Induced nephrotoxicity by ameliorating oxidative stress, apoptosis and inflammation in rats

Acetaminophen (APAP) is used as a primary medication in relieving moderate pain and fever. However, APAP is associated with toxic effects in renal tissue that appear because of its free radicals property. The principle goal of the present work is to assess the kidney damage by APAP and its restore antioxidative property of cinnamon oil (CO). Animals were distributed into six animals each in six groups. Rats were administered with three varying doses of CO from 50 to 200 mg/kg b.w. respectively and only a single dose of APAP. APAP induced an alteration in serum biochemical markers, imbalance in oxidative parameters, morphological changes in kidney tissue along with increased interleukins cytokines (IL-1β & 6) and caspase (3, 9) levels. CO administration significantly ameliorates all the parameters and histopathological changes were restored. Moreover, it also restored the activities of antioxidative enzymes. Our work proved that an variance of oxidative markers in the kidney by APAP is ameliorated by CO in rats. Thus, CO could be used in reducing APAP-induced nephrotoxicity.

Cinnamon oil against acetaminophen-induced acute liver toxicity by attenuating inflammation, oxidative stress and apoptosis

Acetaminophen (APAP) is used as a primary drug due to its antipyretic and analgesic activity. The mechanism of action of APAP toxicity in the liver is due to the depletion of glutathione which elicited free radicals generation. Therefore, the objective of our work is to investigate the APAP induced liver damage and its repair by free radical scavenging activity of cinnamon oil (CO) in male Wistar rats. To investigate the effects of CO at different doses (50, 100 and 200 mg/kg b.w.), animals were given a single oral dose of CO per day for 14 days between 12:00−1:00 PM. The biochemical changes, imbalance in oxidative markers, interleukins, caspases and histopathological studies were determined for quantifying the hepatoprotective effect of CO. One dose of APAP (2 g/kg b.w.) results in significant hepatotoxicity and marked increase the serum markers alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin, albumin, total protein, content of lipid peroxidation (LPO), interleukins (IL-1β, IL-6), caspase-3, -9 expression, DNA fragmentation and histopathological changes were observed. Significant decrease in the levels of LPO, interleukins IL-1β, IL-6, caspase-3, -9 expressions, qualitative as well as quantitative determination of DNA fragments and histopathological changes were reversed by the administration of CO dose dependently. Furthermore, it also restores the depleted activity of antioxidative enzymes. Our study shows that an imbalance in the oxidative parameter in the liver by APAP is restored by treating the animals with CO.

Comparative metabolomic responses of low- and high-cadmium accumulating genotypes reveal the cadmium adaptive mechanism in Brassica napus

Recently, oilseed rape has gathered interest for its ability to withstand elevated metal contents in plant, a key feature for remediation of contaminated soils. In this study, comparative and functional metabolomic analyses using liquid chromatography/mass spectrometry were undertaken to explore the metabolic basis of this attribute under cadmium (Cd) stress. Results revealed both conserved and differential metabolomic responses between genotype CB671 (tolerant Cd-accumulating) and its sensitive counterpart ZD622. CB671 responded to Cd stress by rearranging carbon flux towards production of compatible solutes, sugar storage forms and ascorbate, as well as jasmonates, ethylene and vitamin B6. Intriguingly, IAA abundance was reduced by 1.91-fold, which was in connection with tryptophan funnelling into serotonin (3.48-fold rise). In ZD622 by contrast, Cd provoked drastic depletion of carbohydrates and vitamins, but subtle hormones alteration. A striking accumulation of unsaturated fatty acids and oxylipins in CB671, paralleled by glycerophospholipids build-up and induction of inositol-derived signalling metabolites (up to 5.41-fold) suggested ability for prompt triggering of detoxifying mechanisms. Concomitantly, phytosteroids, monoterpenes and carotenoids were induced, denoting fine-tuned mechanisms for membrane maintenance, which was not evident in ZD622. Further, ZD622 markedly accumulated phenolics from upstream sub-classes of flavonoids; in CB671 however, a distinct phenolic wiring was activated, prioritizing anthocyanins and lignans instead. Along with cell wall (CW) saccharides, the activation of lignans evoked CW priming in CB671. Current results have demonstrated existence of notable metabolomic-based strategies for Cd tolerance in metal-accumulating oilseed rapes, and provided a holistic view of metabolites potentially contributing to Cd tolerance in this species.

Chronic Physical Health Conditions, Mental Health, and Sources of Support in a Longitudinal Australian Child Population Cohort

OBJECTIVE

This study examined associations between chronic physical health conditions (identified from hospital records) that are subject to school health care plans, and children's emotional, behavioral, and social functioning during early (∼5 years of age) and middle childhood (∼11 years).

METHODS

Participants were 21,304 Australian children from a representative longitudinal population cohort derived by multi-agency record linkage. Hospital presentations (admitted patients and emergency department) identified children with asthma (n = 1,573), allergies and anaphylaxis (n = 738), type 1 diabetes (n = 59), epilepsy (n = 87), and any of these conditions (n = 2,275), relative to 19,029 children without these presentations. Logistic regression analyses determined associations between these exposures and (i) emotional, behavioral, social, and overall vulnerabilities reported by teachers (early childhood) and children (middle childhood), and (ii) self-reported lack of sources of support (middle childhood).

RESULTS

Prevalence of any condition in hospital records was 7.5% by early childhood, and 10.7% by middle childhood. Relative to peers without these presentations, small increases in risk of overall problems, and selected emotional, behavioral, and social problems, were apparent for children with any condition, and asthma specifically, in early and middle childhood. Large and pervasive effects were apparent for epilepsy, limited small effects in middle childhood only for allergies and anaphylaxis, and no increases in risk associated with type 1 diabetes examined in middle childhood. No condition was associated with increased risk of lacking supports.

CONCLUSIONS

Children with hospital records of chronic conditions, particularly epilepsy and asthma, might benefit from school-based care plans that integrate their physical and mental health support needs.

Pharmacological melioration by Selenium on the toxicity of tellurium in neuroendocrine centre (Pituitary Gland) in male wistar rats: A mechanistic approach

Purpose

The present research was designed to evaluate the toxicity of tellurium and its prevention by selenium on the pituitary gland in male Wistar rats.

Methods

30 rats were used weighing 200–250 gm, and randomly divided them into five groups. Each group contained an equal number of animals. Group-1 was nominated as control group. Group-2 received an intraperitoneal dose of selenium 0.3  mg per kg body wt. Group-3 was administered with tellurium 4.15 mg per kg body wt. Group-4 was given low-dose (L) of both selenium 0.15 and tellurium 2.075, Group-5 was given High-dose (H) of both selenium 0.3 and tellurium 4.15 mg/kg body wt. orally once in a day. After 15 days of dosing, the behavioral activities- motor co-ordination rotarod and grip strength test were measured. On 16th-day animals were sacrificed and activity of LPO, GSH, caspase-3, caspase-9, GPx, GR, SOD, catalase, and AChE were performed on the pituitary gland as per standard method reported.

Results

Se when given together with Te, significantly protects the motor coordination up to 32.5%, and also protects the grip strength up to 75% in group 4 and 5 respectively as compared to group- 3. Se + Te treatment protects the activity of TBARS up to 48.68% and GSH is 58%. As compared to control, it protects caspase-3 up to 118% and caspase-9 up to 83%. The level of AChE was also observed to be modulated by the administration of Se in Group- 4 and 5. Se + Te protected AChE up to 28.6%. Similar findings were observed for the biochemical activities of GPx (140% protection), SOD (458%), GR (159%), and catalase (95%) activities that were protected significantly Se + Te in Group- 4 and 5.

Conclusion

Selenium dose-dependently protects behavioral activities. It also protects apoptosis, oxidative stress, and AChE activities in the pituitary gland.
