A demographic study on vitiligo (sheti) in Bangladesh

Vitiligo is quite prevalent and constitutes a major psychological health problem in Bangladesh. To determine the effects and extent distribution of Vitiligo among the people, we mainly focused on the sociodemographic studies on Vitiligo in Bangladesh. The patients volunteered in this study were randomly selected from the Skin and Venereal disease department of Rajshahi Medical college hospital, Rajshahi, Bangladesh during 2009-2011. In this sociodemographic studies 125 vitiligo patients of different age groups were carried out. Age distribution, Sex incidence, occupation, itching, life living status, food allergy, social problem were studied. In this study, disease incidence was the highest 44% among 11-20 years age group. In case of sex incidence the female patients were 56%, on the other hand, male recorded 44%. The demographic characteristic showed that the students were the highest percentage (48%) suffering with Vitiligo by occupation. Family history was the most important survey in this study. 32% patients said they had prior to family history. The maximum patients had living status of middle class (40%). In this study 24% patient complained about Food allergy and the participant patient also complained the social problem of Vitiligo. Eighty percent patients reported that most of the person avoids them because general people know that Vitiligo is an infectious disease. This study will give the social consciousness about Vitiligo i.e. it is not an infectious disease

Financial Difficulties Correlate With Mental Health Among Bangladeshi Residents Amid COVID-19 Pandemic: Findings From a Cross-Sectional Survey

Background: The COVID-19 pandemic is a global threat which has challenged mental resilience and impacted the psychological well-being of people across all age groups globally. The present study aimed to investigate how financial difficulties during the pandemic correlate with mental health among residents of Bangladesh. Methods: A cross-sectional survey was conducted on 4,020 residents from different parts of Bangladesh between July and September 2020, during a period of elevated risk of COVID-19 infection. A self-reported online questionnaire comprising socio-demographic, financial difficulties and psychometric measures (to assess depression, anxiety and stress) was used to gather information from participants. Multivariable logistic regression analysis was performed to determine the factors associated with mental health consequences. Results: The prevalence of depression, anxiety, and stress in the sample were 71.1%, 62.3%, and 56.7%, respectively. Levels of depression, anxiety, and stress were significantly higher among participants who reported female sex, being unmarried, smaller families, higher monthly family income, poor self-perceived health status, living near people who had been infected by COVID-19, probability of decreased income, food scarcity (both during the pandemic and in the future) and the possibility of unemployment. However, due to the nature of the cross-sectional study performed with a convenience sampling method, the causal relationship between variables cannot be justified. Conclusions: After several months of the COVID-19 pandemic in Bangladesh, more than half of the respondents rated their mental health concerns as moderate to severe. The findings highlight the contributing factors of poor mental health which warrant the creation of interventions that address the economic, financial and mental health impacts of the pandemic

Tissue-specific interactions of TNI isoforms with other TN subunits and tropomyosins in C. elegans: The role of the C- and N-terminal extensions

The aim of this study is to investigate the function of the C-terminal extension of three troponin I isoforms, that are unique to the body wall muscles of Caenorhabditis elegans and to understand the molecular interactions within the TN complex between troponin I with troponin C/T, and tropomyosin. We constructed several expression vectors to generate recombinant proteins of three body wall and one pharyngeal troponin I isoforms in Escherichia coli. Protein overlay assays and Western blot analyses were performed using antibodies. We demonstrated that pharyngeal TNI-4 interacted with only the pharyngeal isoforms of troponin C/T and tropomyosin. In contrast, the body wall TNI-2 bound both the body wall and pharyngeal isoforms of these components. Similar to other invertebrates, the N-terminus of troponin I contributes to interactions with troponin C. Full-length troponin I was essential for interactions with tropomyosin isoforms. Deletion of the C-terminal extension had no direct effect on the binding of the body wall troponin I to other muscle thin filament troponin C/T and tropomyosin isoforms

Biochemical effects of commercial feedstuffs on the fry of climbing perch (Anabas testudineus) and its impact on Swiss albino mice as an animal model

This study assesses the biochemical effects of commercially available fish feedstuffs on the fry of climbing perch (Anabas testudineus). Subsequently, its impact on experimental animal, Swiss albino mice, is also examined. In order to access the impact of commercial fish feed and feed consumption fish on the experimental animal, the proximate, biochemical and histopathological analyses were done using standard methods. The proximate composition as well as the concentrations of Pb, Ni, Mn, As, Zn, and Cd in the fish feed, different parts of the A. testudineus fish and different parts of the A. testudineus fish-treated experimental mice liver, were all determined using Energy Dispersive X-ray Fluorescence (EDXRF) Spectrometry. The highest levels of Cr, Pb and As were observed in the liver of Swiss albino mice treated with FFT2 and FFBB2 and their concentrations were 0.156, 0.491, 0.172 μg/g and 0.166, 0.771, 0.157 μg/g respectively. No significant changes of protein, fat, crude fiber, moisture and ash contents were observed after proximate composition analysis of fish feeds, A. testudineus and A. testudineus treated experimental mice.Significant amounts of heavy metals (Cr, Mn, Zn Cu, Ni) were found in fish feed, different parts of A. testudineus fish and in the experimental mice. However, remarkably high amounts were observed in the A. testudineus fish’s head and bone with body parts. Biochemical analysis of blood samples of A. testudineus fish treated experimental mice indicated that the cholesterol, TG, LDL and glucose levels were significantly higher. Yet no significant alteration in the HDL level was observed when compared to the control. In histopathological analysis, a remarkable degeneration was observed in the liver and kidney of A. testudineus treated mice. It can therefore be concluded that although A. testudineus has nutritional benefits the quality of this fish may be compromised as a consequence of contamination through various anthropogenic activities. This analysis suggests the commercial fish feed producers must take special caution to reduce the toxic metals in various fish feed products and make it nutritionally rich and safe for fish to eat. Finally, it needs to be safe for human consumption as well. Keywords: Anabas testudineus, Biochemical effects, Commercial feedstuff, Heavy metal, Histopathological analysi
