Receptor model-based sources and risk assessment of metals in sediment of the coastal construction-oriented aquatic system in Bangladesh. MARINE POLLUTION BULLETIN 2024; 202:116383. [PMID: 38677105 DOI: 10.1016/j.marpolbul.2024.116383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2024] [Revised: 04/12/2024] [Accepted: 04/13/2024] [Indexed: 04/29/2024]
Abstract
Metal pollution in sediment from construction areas raises ecological and health concerns, yet source-based sediment pollution in Bangladesh remains understudied. Our investigation focused on fifteen locations in the Kohelia River and the coastal regions near the Matarbari projects (Matarbari Power Plant, Matarbari Deep Seaport), assessing metal concentrations' sources and impacts on ecology and human well-being. Sediment quality indices indicated high Cd and Cr contamination, with sites near Matarbari projects being the most polluted. The positive matrix factorization model identified three anthropogenic sources and mixed sources. Matarbari projects contributed significantly to As (67.9 %), Mn (50.25 %), Cd (48.35 %), and Cr (41.0 %), while ship-breaking yards contributed Fe (58.0 %), Zn (55.5 %), Pb (53.8 %), and Cu (36.1 %). Ecological indices showed different impacts on aquatic life from metal pollution, but cancer risk levels stayed below the threshold set by the US Environmental Protection Agency. These findings underscore the need for targeted measures to address metal pollution.

Sci Rep 2024; 14:7737. [PMID: 38565564 PMCID: PMC10987614 DOI: 10.1038/s41598-024-58126-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 03/26/2024] [Indexed: 04/04/2024] Open
Abstract
Research has indicated a negative impact of physical activity on academic burnout among students, however, there is a paucity of evidence about the underlying mechanism of this association in Pakistani students. The present research seeks to investigate the relationship between physical activity and academic burnout by investigating the potential mediating effects of adherence to the Mediterranean diet (MD) and body mass index (BMI). A sample of 596 students using a cross-sectional survey design was gathered from two public universities (Riphah International University and Mohammed Ali Jinnah University) in Rawalpindi, Pakistan from June to July 2022. The study participants were asked to fill out the Physical Activity Rating Scale-3, the Learning Burnout Scale, and the Test of Adherence to MD questionnaires. The study employed descriptive, bivariate, and path analysis through regression utilizing the SPSS software version 27. The findings demonstrated a negative correlation between academic burnout and BMI, physical activity, and adherence to the MD. The relationship between physical activity and academic burnout was mediated by BMI. Physical activity and academic burnout were inversely correlated, with adherence to the MD and BMI interacting as sequential mediators. The outcomes of this research have expanded our knowledge of the association between physical activity and academic burnout and have suggested crucial and appropriate strategies for addressing student academic burnout.

Abstract
Guillain-Barre Syndrome (GBS) is considered as an immune mediated inflammatory disease of peripheral nerves and nerve roots. The significance of CSF total protein (CSF-TP) in subtypes of Guillain-Barre syndrome has not been well established. This observational, cross sectional study's aim was to identify association of CSF total protein with clinical heterogeneity, disease severity and electrophysiological subtypes in GBS patients. This study was carried out in the Department of Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh from September 2017 to February 2019 on 50 (fifty) admitted GBS patients as per inclusion and exclusion criteria. About 3-5 ml of CSF was taken around 10±2 days from disease onset for detection CSF cell count and protein. Pattern of clinical presentation, disability status by Hughes scale and NCS findings of these patients was documented. Mean CSF-TP were substantially higher for Sensori-motor GBS (195.42 mg/dl) and GBS with cranial involvement (226.12 mg/dl) than that of GBS with motor (134.00 mg/dl) and autonomic involvement (155.21 mg/dl). Mean CSF total protein (CSF-MTP) in severely ill GBS patients (Grade-IV) was 217.04 mg/dl and very severely ill GBS patients (Grade-V) was 138.00mg/dl which was significantly higher than mean CSF total protein in mild GBS patients (CSF-MTP: 99.86mg/dl) and moderately ill GBS patients (CSF-MTP: 172.00 mg/dl). Mean CSF total protein is 245.00mg/dl in AIDP which is also higher than mean CSF total protein of AMAN (153.36 mg/dl) and AMSAN (165.17mg/dl). CSF-TP is thought to be a sensitive test for GBS in the second week after onset, but it may be a reliable predictor of clinical severity. There is a significant association of CSF-TP elevation with demyelinating electrophysiologic pattern.

Abstract
Stroke is the second-leading cause of death and also a leading cause of combined death and disability. In Bangladesh, stroke prevalence is 11.39 per 1000 population, but highest prevalence of stroke is 14.71 per 1000 population in the Mymensingh division. Hyperuricemia has been reported as an independent risk factor for stroke in different studies and a significant association between serum uric acid and dyslipidemia has also been stated. On the contrary, some studies suggest that uric acid has a neuroprotective role. This cross-sectional study was completed in the Medicine Department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from March 2021 to January 2023. In this cross-sectional study, 352 adult acute ischemic stroke patients were included from the Medicine Department of Mymensingh Medical College Hospital. Serum uric acid and fasting serum lipid levels were measured within 48 hours of admission. The mean age ±SD of the respondents was 61.9±12.8 years. Hyperuricemia was found among 18.2% of respondents, whose mean ±SD serum uric acid was 5.7±1.9 mg/dl. Dyslipidemia was present in 88.4% of patients. The mean ±SD of the National Institutes of Health Stroke Scale (NIHSS) score was 12.0±5.9. Most of the patients (65.6%) were suffering from moderate stroke, followed by moderate to severe stroke (15.1%), severe stroke (10.8%) and minor stroke (8.5%). After multiple linear regressions, the independent variables age, gender, serum uric acid and total cholesterol were found to be significant predictors of the NIHSS score of the respondents. In conclusion, the majority of acute ischemic stroke patients have an association with dyslipidemia, but only around one-fifth of patients have hyperuricemia. There is a significant association of high serum uric acid and high serum total cholesterol with stroke severity (NIHSS score). But low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and, triglycerides have no association with stroke severity.

Assessing stocks of Mystus tengara (Hamilton, 1822) from three different management systems in Baors (Oxbow lake) of southwest Bangladesh: Implications for sustainable management. Heliyon 2024; 10:e26751. [PMID: 38449596 PMCID: PMC10915391 DOI: 10.1016/j.heliyon.2024.e26751] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 02/10/2024] [Accepted: 02/19/2024] [Indexed: 03/08/2024] Open
Abstract
This study was conducted to observe the stock assessments of Tengara (Mystus tengara) in three different management systems of Baors (Oxbow lake) such as System-1, System-2, and System-3. In this study, 1806 specimens were sampled using traditional fishing nets to observe growth pattern, population structure, growth parameters, natural mortality (M), fishing mortality (F), total mortality (Z), recruitment pattern, exploitation rate (E), relative yield per-recruit (Y'/R), optimum catchable length, length at first capture, steady state biomass (SSB), and maximum sustainable yield (MSY) from January to December 2021. Digital slide calipers and a digital balance were used to measure each individual's total length (TL) and body weight (BW), respectively. An empirical maximum length-based model was used to calculate size at first sexual maturity (Lm), and optimum catchable length (Lopt) was calculated based on asymptotic length (L∞). The least square linear regression equation was used to determine the regression parameters. The value of regression parameter, 'b' was 3.01 for system-1, 2.78 for system-2, and 2.70 for system-3, indicating that growth pattern of Tengara is isometric in system-1, but negative allometric growth in system-2 and system-3. The highest asymptotic length (L∞) and weight (W∞) of Tengara were found in system-1 (11.19 cm and 13.67 g) in comparison with system-2, (10.98 cm and 12.49 g) and system-3 (9.09 cm and 6.96 g) respectively. The growth coefficient (K) of the von Bertalanffy growth function (VBGF) was 0.72 year-1, 0.72 year-1, and 0.73 year-1 for system-1, system-2 and system-3, respectively. The calculated M, F, Z were 1.72, 1.28, and 3.00 year-1 for system-1, 1.11, 0.67 and 1.78 year-1 for system-2 and 1.12, 0.84 and 1.96 year-1 for system-3 respectively. The calculated life span (tmax) was found 4.19 years for system-1, 4.15 years for system-2 and 4.12 years for system-3. The recruitment patterns showed that the highest relative percentage of recruits were found in July, June and September for system-1, system-2 and system-3 respectively, with the major recruitment peak occurring from April to June for system-1, May to June for system-2 and June to July for system-3. One minor recruitment peak also occurred from August to September in system-1. The exploitation rate was more or less same in all three systems indicating that Tengara is under exploited from all the Baors. The significantly highest SSB and MSY were found in system-1 (22.65 and 12.11 metric tons), compared to system-2 (16.16 and 10.28 metric tons) and system-3 (5.55 and 5.49 metric tons), respectively. Considering the values of regression parameters, recruitment pattern, SSB and MSY, system-1 was found more suitable for Tengara compared to system-2 and system-3 management practices of Baors. Finally, these findings will turn out to be paradigm for the impregnable management of Tengara in Baors of southwest Bangladesh.

Abstract
During this coronavirus pandemic, when a lot of people are already severely afflicted with SARS-CoV-19, the dispersion of black fungus is making it worse, especially in the Indian subcontinent. Considering this situation, the idea for an in silico study to identify the potential inhibitor against black fungal infection is envisioned and computational analysis has been conducted with isatin derivatives that exhibit considerable antifungal activity. Through this in silico study, several pharmacokinetics properties like absorption, distribution, metabolism, excretion, and toxicity (ADMET) are estimated for various derivatives. Lipinski rules have been used to observe the drug likeliness property, and to study the electronic properties of the molecules, quantum mechanism was analyzed using the density functional theory (DFT). After applying molecular docking of the isatin derivatives with sterol 14-alpha demethylase enzyme of black fungus, a far higher docking affinity score has been observed for the isatin sulfonamide-34 (derivative 1) than the standard fluconazole. Lastly, molecular dynamic (MD) simulation has been performed for 100 ns to examine the stability of the proposed drug complex by estimating Root Mean Square Deviation (RMSD), Radius of gyration (Rg), Solvent accessible surface area (SASA), Root Mean Square Fluctuation (RMSF), as well as hydrogen bond. Listed ligands have precisely satisfied every pharmacokinetics requirement for a qualified drug candidate and they are non-toxic, non-carcinogenic, and have high stability. This natural molecule known as isatin derivative 1 has shown the potential of being a drug for fungal treatment. However, the impact of the chemicals on living cells requires more investigation and research.

Abstract
This paper aims to elucidate a comprehensive biographical account of Zohra Begum Kazi, the pioneering Bengali female doctor in Bangladesh. Her professional journey commenced during the British colonial time, achieved prominence during the era of Pakistan, and ultimately reached the pinnacle of her life's accomplishments in the independent Bangladesh. Despite her distinguished medical career, her life was significantly shaped by sundry historical discourses, endowing her with the attributes of a philanthropist, a revolutionist, and a nationalist. This study seeks to assess her multifaceted contributions in three distinct dimensions: firstly, her role as a medical doctor; secondly, her engagement in the nationalist movement, and thirdly, her intellectual influence as a moral and social philosopher. Through this multifaceted analysis, we aim to consign her within the annals of Bangladesh's national history as the leading Bengali female doctor.

Abstract
Piperine is a natural alkaloid that possesses a variety of therapeutic properties, including anti-inflammatory, antioxidant, antibacterial, and anticarcinogenic activities. The present study aims to assess the medicinal benefits of piperine as an anti-diarrheal agent in a chick model by utilizing in vivo and in silico techniques. For this, castor oil was administered orally to 2-day-old chicks to cause diarrhea. Bismuth subsalicylate (10 mg/kg), loperamide (3 mg/kg), and nifedipine (2.5 mg/kg) were used as positive controls, while the vehicle was utilized as a negative control. Two different doses (25 and 50 mg/kg b.w.) of the test sample (piperine) were administered orally, and the highest dose was tested with standards to investigate the synergistic activity of the test sample. In our findings, piperine prolonged the latent period while reducing the number of diarrheal feces in the experimental chicks during the monitoring period (4 h). At higher doses, piperine appears to reduce diarrheal secretion while increasing latency in chicks. Throughout the combined pharmacotherapy, piperine outperformed bismuth subsalicylate and nifedipine in terms of anti-diarrheal effects with loperamide. In molecular docking, piperine exhibited higher binding affinities towards different inflammatory enzymes such as cyclooxygenase 1 (-7.9 kcal/mol), cyclooxygenase 2 (-8.4 kcal/mol), nitric oxide synthases (-8.9 kcal/mol), and L-type calcium channel (-8.8 kcal/mol), indicating better interaction of PP with these proteins. In conclusion, piperine showed a potent anti-diarrheal effect in castor oil-induced diarrheal chicks by suppressing the inflammation and calcium ion influx induced by castor oil.

Abstract
BACKGROUND Children's development is multifactorial. Although there have been several studies exploring the association of children's development with maternal, child, and environmental factors, we are unaware of any study that assessed those factors in children whose mothers were enrolled in a social safety net programme in low- and middle-income countries. This study aimed to identify the factors associated with disadvantaged children's cognitive, language, and motor development at age 6-16 months in deprived settings of urban Bangladesh and to identify relative importance of these factors of children's development. We also explored if there were any gender differences in child development. METHODS This cross-sectional study was conducted in a deprived setting of urban Bangladesh. Bayley III was used for assessing children's cognitive, language, and motor development. Multivariable linear regression model was used to find the factors associated with children's development, and dominance analysis was used to explore the relative importance of the factors. RESULTS Out of the total 599 mother-child dyads, 303 (50.58%) were girls. The factors associated with children's development were length-for-age Z-score (cognitive: B = 1.21 [95% CI = 0.31, 2.11], P = 0.008; language: 1.67 [0.79, 2.55] P < 0.001; motor: 2.15 [1.01, 3.29] P < 0.001) and home environment (cognitive: 0.58 [0.27, 0.89] P < 0.001; language: 0.59 [0.27, 0.92], P < 0.001; motor: 0.44 [0.09, 0.79] P = 0.013). Girls had higher cognitive (1.90 [0.17, 3.6], P = 0.031) and language (2.53 [0.55, 4.51], P = 0.013) development compared with boys. Families with a higher number of under five children within the households had lower language (-1.57 [-2.78, -0.36], P = 0.011) development. Violence against the mother and the families' food security status were not associated with the children's development. Children's length-for-age Z-score (27%) and home stimulation environment (23%) were the most important factors of cognitive development. CONCLUSION Children's nutritional status and home environment are important factors for disadvantaged children's development in deprived urban settings of Bangladesh. Both early child development-focussed parenting and nutrition interventions should be considered when designing child development programmes in urban settings in low- and middle-income countries.

Abstract
HYPOTHESIS Colloidal surface morphology determines suspension properties and applications. While existing methods are effective at generating specific features on spherical particles, an approach extending this to non-spherical particles is currently missing. Synthesizing un-crosslinked polymer microspheres with controlled chemical patchiness would allow subsequent thermomechanical stretching to translate surface topographical features to ellipsoidal particles. EXPERIMENTS A systematic study using seeded emulsion polymerization to create polystyrene (PS) microspheres with controlled surface patches of poly(tert-butyl acrylate) (PtBA) was performed with different polymerization parameters such as concentration of tBA monomer, co-swelling agent, and initiator. Thermomechanical stretching converted seed spheres to microellipsoids. Acid catalyzed hydrolysis (ACH) was performed to remove the patch domains. Roughness was characterized before and after ACH using atomic force microscopy. FINDINGS PS spheres with controlled chemical patchiness were synthesized. A balance between two factors, domain coalescence from reduced viscosity and domain growth via monomer absorption, dictates the final PtBA) patch features. ACH mediated removal of patch domains produced either golf ball-like porous particles or multicavity particles, depending on the size of the precursor patches. Patchy microspheres were successfully stretched into microellipsoids while retaining their surface characteristics. Particle roughness is governed by the patch geometry and increases after ACH. Overall, this study provides a facile yet controllable platform for creating colloids with highly adjustable surface patterns.

Abstract
The Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is a potentially lethal infection that presents a substantial threat to health, especially in Middle East nations. Given that no FDA-approved specific therapy for MERS infection exists, designing and discovering a potent antiviral therapy for MERS-CoV is crucial. One pivotal strategy for inhibiting MERS replication is to focus on the viral main protease (Mpro). In this study, we identify potential novel Mpro inhibitors employing structure-based virtual screening of our recently reported Ugi reaction-derived library (URDL) consisting of cherry-picked molecules from the literature. The key features of the URDL library include synthetic tractability (1-2 pot synthesis) of the molecules scaffold and unexplored chemical space. The hits were ranked based on the docking score, MM-GBSA free energy of binding, and the interaction pattern with the active site residues. A molecular dynamics (MD) simulation study was performed for the first two top-ranked compounds to analyze the stability and free binding energy based on the molecular mechanics Poisson-Boltzmann surface area. The potential mean force calculated from the steered molecular dynamics (SMD) simulations of the hits indicates improved H-bond potential, enhanced conformational stability, and binding affinity toward the target, compared to the cocrystallized ligand. The discovered hits represent novel synthetically tractable scaffolds as potential MERS-CoV Mpro inhibitors.Communicated by Ramaswamy H. Sarma.

Abstract
A novel semi-organic crystal has been grown using slow evaporation technique by doping organic compound L-asparagine monohydrate (C4H8N2O3·H2O) with inorganic material Magnesium sulphate heptahydrate (MgSO4·7H2O). The crystallographic parameters like strain, dislocation density and crystallite size were calculated by powder X-ray diffraction method. Functional groups were identified and bond length, force constants were calculated from FT-IR spectroscopy. Energy dispersive X-ray (EDX) analysis was used to identify the constituent elements of the crystal. Kinetic and thermodynamic parameters, such as, activation energy Ea, change in Gibb's free energy (ΔG) and change in enthalpy (ΔH) have been determined by thermogravimetric analysis (TGA) analysis. Ea, ΔH and ΔG show positive values and change in entropy (ΔS) shows negative ones. The thermal degradation behavior of the crystals has been analyzed by differential scanning calorimetry (DSC) analysis. Various optical constants such as optical band gap, lattice dielectric constant, absorbance, extinction coefficient, the ratio of free charge carrier concentration to the effective mass, Urbach energy, optical and electrical conductivities were estimated from UV-vis transmittance data. High optical conductivity (1010 s-1) justifies the good photo response nature of the semi-organic crystal.

Abstract
Vitamin D is important for health and disease. Milk is a good natural source of it, and calcium-vitamin D supplements are widely available over-the-counter and prescribed in clinical practice. But the effect of milk intake and calcium-vitamin D supplementation on serum vitamin D status is not known. This cross-sectional study was done to see the relationship between vitamin D status and milk intake or oral calcium-vitamin D supplementation using a structured questionnaire and carried out in a private consultation centre of Dhaka city, the capital of Bangladesh from July 2017 to March 2018. Serum 25-hydroxyvitamin D [25(OH)D] level was measured by radioimmunoassay. Out of 259 patients, 64.1% had vitamin D deficiency defined as serum 25(OH)D level <20ng/mL. Sixty one percent of those who had serum 25(OH)D level <20ng/mL did not take milk or milk products, while 53.0% of those having 25(OH)D level ≥20ng/mL did not take milk. Approximately 89.0% of those who had serum 25(OH)D level <20ng/mL did not take oral calcium-vitamin D, whereas 72.0% of those having 25(OH)D level ≥20ng/mL did not take oral calcium-vitamin D (p=0.001). In the multiple logistic regression analysis, there were significantly increased odds of vitamin D deficiency for females as compared to males [odds ratio (OR) 2.48, 95% confidence interval (CI) 1.34-4.56] and not taking oral vitamin D as compared to taking oral vitamin D (OR 3.56, 95% CI 1.74-7.28). Vitamin D deficiency is widely prevalent. Lack of milk intake and calcium-vitamin D supplementation are more commonly associated with serum vitamin D deficiency, and calcium-vitamin D supplementation is specially important in females.

Abstract
Upper back pain is as painful or troublesome as the pain in the lower back or the neck. Myofascial pain syndrome which is most common cause of upper back pain is characterized by localized musculoskeletal pain and tenderness in association with trigger points. The aim of the study was to correlate the improvement of myofascial pain syndrome patients with proper and timely physical therapy. This quasi experimental study was conducted in the department of Physical Medicine and Rehabilitation, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh, from 1st January 2008 to 31st August 2008 to see the role of rehabilitation exercise on myofascial pain syndrome causing upper back pain. Sixty (60) patients of myofascial pain syndrome causing upper back pain were randomly assigned for treatment; out of which 23(38.33%) were male and 37(61.66%) were female. The male and female ratio was 1:1.6. The patients selected for the trial were divided into two groups: Group A and Group B. In group A (n=28) the patients were treated with thermotherapy- Microwave diathermy, non-steroidal anti inflammatory drugs and activities of daily living instructions and in Group B (n=32) with same interventions in addition to rehabilitation exercises. Treatment duration was 6 weeks. The difference of treatment improvement was statistically significant (p<0.05) from 1st week up to 6th week. After complete course of treatment 67.86% patients in Group A and 78.13% patients in group B reported improvement. So rehabilitation exercises can be a valuable adjunct to other modalities of treatment of myofascial pain syndrome causing upper back pain.

Abstract
Approximately 10.0% of tuberculosis (TB) Infected individuals develop clinical disease in the absence of immune suppression suggests that individual factors may play a role in the response to infection. Body's immune function is boosted by micronutrient and also plays a major role in response to tubercular infection. Someone, may argue that cell mediated immunity is compromised in iron deficiency before anemia becomes apparent. This descriptive observational study intended to assess serum iron profile in patients suffering from pulmonary tuberculosis. This study included 56 newly diagnosed sputum smear positive and negative pulmonary tuberculosis patients as per inclusion and exclusion criteria and was conducted at the department of the Internal Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Bangladesh with the collaboration of the Biochemistry department, BSMMU, Bangladesh from February 2017 to January 2018. Collected data were recorded in a structured questionnaire and compiled and appropriate analyses were done by using computer-based software Statistical Package for Social Sciences (SPSS) version 23.0. Out of 56 patients, majority was young and at reproductive age, male was predominant (78.6%) with a male to female ratio of 3.7:1. More than three fourth 43(81.0%) patients were found to have low serum iron concentration. Majority 45(80.4%) patients had normal serum TIBC, 6(10.7%) had low serum total iron binding capacity (TIBC) and 5(8.9%) had high serum TIBC. Almost two third 36(64.3%) patients had low serum transferrin saturation and 20(35.7%) had normal serum transferrin saturation. Majority 31(55.4%) patients had normal serum ferritin, 2(3.6%) had low serum ferritin and 23(41.1%) had high serum ferritin. Serum iron concentration and serum ferritin were significantly associated with chest x-ray abnormalities (p<0.01). Half of the patients were smear positive for acid fast bacilli (AFB) (50.0%). No significant association was found between sputum positive for AFB with iron profile status. In smear positive pulmonary tuberculosis patients, more than three fourth (78.6%) patients had low serum iron concentration at baseline and majority 20(80.0%) patients had normal serum iron concentration after 2(two) months. Mean serum iron concentration was 41.8±17.6mcg/l in baseline and 70.4±29.7mcg/l in at 2(two) month. More than sixty percent (60.7%) patients had low serum transferrin saturation at baseline and 20(80.0%) patients had normal serum transferrin saturation after 2(two) months. Mean serum transferrin saturation was 18.1±7.6% at baseline and 31.2±19.4% in at 2(two) months. After 2(two) months follow up serum iron concentration and serum transferrin saturation had significant improvement (p<0.05). Significant iron deficiency status occurred in pulpmonary tuberculosis and which improved after anti-tubercular treatment without iron supplementation.

Abstract
Coronary artery disease (CAD) is one of the important causes of mortality worldwide. South Asians, notably Indians are unduly prone to develop CAD with its incidence being doubled in the last three decades among both rural and urban settlers. CAD prevalence of in Bangladesh is not known. There are merely a limited number of small-scale epidemiological studies are existing. Recent data indicates CAD prevalence in our country to lie between 1.85-3.4% in rural and 19.6% in an urban sample of working professionals. Despite marked disparity in values, the disease seems to be in rising trend. Patients with concomitant CAD and carotid artery disease are at increased risk of developing peri-operative neurological events including stroke. By far, the prevalence of carotid artery disease in candidates of CABG has not yet been determined in our country. There is a lack of pre-operative guidelines as well for the necessary vascular investigations that should be performed on CABG candidates before they go to the operation table. Pre-operative non-invasive carotid Doppler ultrasonography is a useful screening tool for carotid artery disease in all patients undergoing CABG. This was a cross-sectional observational study, was conducted in the Radiology & Imaging department of Ibrahim Cardiac Hospital & Research Institute, Dhaka, Bangladesh from January 2017 to June 2017. The present cross-sectional study was intended to determine the prevalence of concurrent occurrence of carotid and coronary artery disease in elderly patients undergoing CABG. Total 210 elderly (from 60 & above) patients scheduled for CABG taken as study population. There was bilateral carotid atherosclerotic plaque in 15(12.2%) patients. Right carotid plaque was in 69(56.0%) patients, left carotid plaque in 54(43.9%) patients. Carotid stenosis grading was done in percentage (%). There was significant (>50.0%) stenosis of right carotid system in 12 patients (17.4%) and significant stenosis of left carotid system in 18 patients (33.3%). Right carotid system & bulb was the most common site of plaque formation. We can conclude from this study that a substantial proportion of patients after a particular age possess carotid artery disease simultaneously with coronary artery disease, routine evaluation of carotid arteries of the elderly patients scheduled for CABG is strongly suggested.

Mechanistic inhibition of gastric cancer-associated bacteria Helicobacter pylori by selected phytocompounds: A new cutting-edge computational approach. Heliyon 2023; 9:e20670. [PMID: 37876433 PMCID: PMC10590806 DOI: 10.1016/j.heliyon.2023.e20670] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 09/09/2023] [Accepted: 10/04/2023] [Indexed: 10/26/2023] Open
Abstract
Background Helicobacter pylori (H. pylori) is a persistent bacterial inhabitant in the stomachs of approximately half the global populace. This bacterium is directly linked to chronic gastritis, leading to a heightened risk of duodenal and gastric ulcer diseases, and is the predominant risk factor for gastric cancer - the second most common cause of cancer-related deaths globally. The increasing prevalence of antibiotic resistance necessitates the exploration of innovative treatment alternatives to mitigate the H. pylori menace. Methods Initiating our study, we curated a list of thirty phytochemicals based on previous literature and subjected them to molecular docking studies. Subsequently, eight phytocompounds-Glabridin, Isoliquiritin, Sanguinarine, Liquiritin, Glycyrrhetic acid, Beta-carotin, Diosgenin, and Sarsasapogenin-were meticulously chosen based on superior binding scores. These were further subjected to an extensive computational analysis encompassing ADMET profiling, drug-likeness evaluation, principal component analysis (PCA), and molecular dynamic simulations (MDs) in comparison with the conventional drug, Mitomycin. Results The natural compounds investigated demonstrated superior docking affinities to H. pylori targets compared to the standard Mitomycin. Notably, the phytocompounds Diosgenin and Sarsasapogenin stood out due to their exceptional binding affinities and pharmacokinetic properties, including favorable ADMET profiles. Conclusion Our comprehensive and technologically-advanced approach showcases the potential of identified phytocompounds as pioneering therapeutic agents against H. pylori-induced gastric malignancies. In light of our promising in silico results, we recommend these natural compounds as potential candidates for advancing H. pylori-targeted drug development. Given their potential, we strongly advocate for subsequent in vitro and in vivo studies to validate their therapeutic efficacy against this formidable gastrointestinal bacterium.

Abstract
Cerebrovascular disease is the third most familiar cause of mortality worldwide and in Bangladesh. The reported prevalence of stroke in Bangladesh is 0.3%. Age, high serum glucose, elevated admission blood pressure, fever, large infarction size, and hyperhomocysteinemia has been reported to be risk factor for early post-stroke neurological deterioration. Early serum homocysteine level estimation can predict the early prognosis of ischemic stroke. In a developing country like Bangladesh, an earlier stroke outcome prediction for guiding therapeutic approach is essential. This study aimed to specify the role of estimating serum homocysteine during the early phase of acute ischemic stroke to assume an early prognosis that would guide- a management plan, the need to stay in the hospital and the need for intervention. This cross-sectional descriptive study was performed at the Department of Medicine, Mymensingh Medical College Hospital, Bangladesh from October 2021 to April 2022. Radiologically confirmed all ischemic stroke patients admitted at the Department of Medicine, Mymensingh Medical College Hospital, during the study period fulfilling the inclusion and exclusion criteria were included in this study. Non-probability purposive sampling technique was used. Data was collected using a pre-designed case record form. Quantitative data were represented as mean and standard deviation and qualitative data as frequency and percentage. The comparison was made by Chi-square test and independent samples t-test using SPSS (version 26.0). During the study period, among 716 stroke patients, 59 ischemic stroke patients were included in this study. The mean age of the patients was 64.0±11.72 years. After 72 hours of supportive treatment, early neurological outcomes were observed using NIHSS scoring. Out of 59 patients, the condition of 45(76.0%) patients improved or remained stable (END-) and the state of 14(24.0%) patients worsened (END+). Elderly age-raised temperature and elevated blood glucose level are known to increase infarction size, but only elevated temperature (p value 0.009) has statistical significance in this study. The mean homocysteine level ±SD was 20.22±6.95μmol/L, which is above the normal (<15μmol/L). The level was above average for both outcome groups. Serum homocysteine level was significantly higher in END(+) group (31.59±2.98μmol/L) than END(-) group (16.69±2.66μmol/L) and p value was <0.001.

Abstract
Two-photon polymerization lithography is promising for producing three-dimensional structures with user-defined micro- and nanoscale features. Additionally, shrinkage by thermolysis can readily shorten the lattice constant of three-dimensional photonic crystals and enhance their resolution and mechanical properties; however, this technique suffers from non-uniform shrinkage owing to substrate pinning during heating. Here, we develop a simple method using poly(vinyl alcohol)-assisted uniform shrinking of three-dimensional printed structures. Microscopic three-dimensional printed objects are picked and placed onto a receiving substrate, followed by heating to induce shrinkage. We show the successful uniform heat-shrinking of three-dimensional prints with various shapes and sizes, without sacrificial support structures, and observe that the surface properties of the receiving substrate are important factors for uniform shrinking. Moreover, we print a three-dimensional mascot model that is then uniformly shrunk, producing vivid colors from colorless woodpile photonic crystals. The proposed method has significant potential for application in mechanics, optics, and photonics.

Abstract
Plastic represents an essential material in our society; however, a major imbalance between their high production and end-of-life management is leading to unrecovered energy, economic hardship, and a high carbon footprint. The adoption of plastic recycling has been limited, mainly due to the difficulty of recycling mixed plastics. Here, we report a versatile organocatalyst for selective glycolysis of diverse consumer plastics and their mixed waste streams into valuable chemicals. The developed organocatalyst selectively deconstructs condensation polymers at a specific temperature, and additives or other polymers such as polyolefin or cellulose can be readily separated from the mixed plastics, providing a chemical recycling path for many existing mixed plastics today. The Life Cycle Assessment indicates that the production of various condensation polymers from the deconstructed monomers will result in a significant reduction in greenhouse gas emissions and energy input, opening a new paradigm of plastic circularity toward a net-zero carbon society.

Abstract
Fruits and vegetables are used not only for nutritional purposes but also as therapeutics to treat various diseases and ailments. These food items are prominent sources of phytochemicals that exhibit chemopreventive and therapeutic effects against several diseases. Hirsutine (HSN) is a naturally occurring indole alkaloid found in various Uncaria species and has a multitude of therapeutic benefits. It is found in foodstuffs such as fish, seafood, meat, poultry, dairy, and some grain products among other things. In addition, it is present in fruits and vegetables including corn, cauliflower, mushrooms, potatoes, bamboo shoots, bananas, cantaloupe, and citrus fruits. The primary emphasis of this study is to summarize the pharmacological activities and the underlying mechanisms of HSN against different diseases, as well as the biopharmaceutical features. For this, data were collected (up to date as of 1 July 2023) from various reliable and authentic literature by searching different academic search engines, including PubMed, Springer Link, Scopus, Wiley Online, Web of Science, ScienceDirect, and Google Scholar. Findings indicated that HSN exerts several effects in various preclinical and pharmacological experimental systems. It exhibits anti-inflammatory, antiviral, anti-diabetic, and antioxidant activities with beneficial effects in neurological and cardiovascular diseases. Our findings also indicate that HSN exerts promising anticancer potentials via several molecular mechanisms, including apoptotic cell death, induction of oxidative stress, cytotoxic effect, anti-proliferative effect, genotoxic effect, and inhibition of cancer cell migration and invasion against various cancers such as lung, breast, and antitumor effects in human T-cell leukemia. Taken all together, findings from this study show that HSN can be a promising therapeutic agent to treat various diseases including cancer.

Abstract
The COVID-19 coronavirus, which primarily affects the lungs, is the source of the disease known as SARS-CoV-2. According to "Smoking and COVID-19: a scoping review," about 32% of smokers had a severe case of COVID-19 pneumonia at their admission time and 15% of non-smokers had this case of COVID-19 pneumonia. We were able to determine which genes were expressed differently in each group by comparing the expression of gene transcriptomic datasets of COVID-19 patients, smokers, and healthy controls. In all, 37 dysregulated genes are common in COVID-19 patients and smokers, according to our analysis. We have applied all important methods namely protein-protein interaction, hub-protein interaction, drug-protein interaction, tf-gene interaction, and gene-MiRNA interaction of bioinformatics to analyze to understand deeply the connection between both smoking and COVID-19 severity. We have also analyzed Pathways and Gene Ontology where 5 significant signaling pathways were validated with previous literature. Also, we verified 7 hub-proteins, and finally, we validated a total of 7 drugs with the previous study.

Abstract
Haematohidrosisis manifested by sweating mixed with blood. It is a rare disease and there are scarce literature regarding case report. We are describing five cases of haematohidrosis in different age group here in this case series. In case 1- a 20 year old woman was admitted with history of recurrent haemorrhage from various sites without any trauma or anticoagulant or antipletlet medication. There was no evidence of local trauma. Physical examination was unremarkable. Her blood workup came out insignificant. In case 2- a 10 year old boy was admitted with epistaxis, conjunctival bleeding, haematuria and per rectal bleeding without any history of injury. He had no history of medicine which would cause bleeding. Physical examination and laboratory profile were insignificant. In case 3- a 15 year old boy presented with recurrent haematuria and conjunctival haemorrhage without any trauma. No history of medication that would cause the bleeding. His systemic examination and laboratory profile was unremarkable. In case 4- a 25 year old woman presented with bleeding from ear, nose and eyes without any local trauma. She was not on any medication that would cause bleeding. Her systemic inquiry and laboratory profile was unremarkable. In case 5- a 20 year old woman presented with bleeding from eyes, ears and umbilicus. There was no evidence of self-inflicted injury. She had features of anxiety disorder. Other systemic examination and laboratory profile was unremarkable. All the cases were labelled as haematohidrosis and treated with propranolol with successful outcome. We report this case series to build up awareness and disseminate clinical knowledge.
