Maternal exposure to the endocrine disruptor bisphenol A (BPA) has been linked offspring reproductive abnormalities. However, exactly how BPA affects fertility remains poorly understood.The aim of present study was evaluate effects gestational on sperm function, fertility, and proteome profile F1 spermatozoa in adult mice.Pregnant CD-1 mice (F0) were gavaged with at three different doses (50 μg/kg bw/day, 5 mg/kg 50 bw/day) embryonic days 7 14. We investigated related processes postnatal day...
Mortality in ducks and geese caused by highly pathogenic avian influenza A(H5N1) infection had not been previously identified Bangladesh. In June-July 2011, we investigated mortality ducks, chickens with suspected H5N1 a north-eastern district of the country to identify aetiologic agent extent outbreak possible associated human infections. We surveyed households farms affected poultry flocks six villages Netrokona collected cloacal oropharyngeal swabs from sick birds tissue samples dead...
Studies regarding bisphenol A (BPA) exposure and male (in)fertility have conventionally focused on modifications in ejaculated spermatozoa function from exposed individuals. However, mammalian are incapable of fertilization prior to achieving capacitation, the penultimate step maturation. Therefore, it is necessary investigate BPA-induced changes capacitated assess consequences subsequent fertilization. Here, we demonstrate effect gestational BPA (50 μg/kg bw/day, 5 mg/kg 50 bw/day)...
Abstract The endocrine disruptor bisphenol A (BPA) is well known for its adverse effect on male fertility. Growing evidence suggests that BPA may interact with testicular germ cells and cause infertility as a result of estrogenic activity. Objective current in vitro study was to investigate the proliferation, survivability stemness properties mouse exposed BPA, evaluate possible expression cellular proteome. Our results showed cell viability proliferation were not affected by low...
Burn has terrible consequences for the affected patients, making them vulnerable to wound infections and septicemia, which results in physical mental disability death, necessitating superior treatment options. Human amniotic membrane (HAM) been utilized burn wounds decades its low immunogenicity, angiogenic, anti‐inflammatory, antimicrobial properties promoting epithelialization. Silver nanoparticles (AgNPs), on other hand, have promote fibroblast migration. This study aimed determine...
Bisphenol-A (BPA) exposure in an adult male can affect the reproductive system, which may also adversely next generation. However, there is a lack of comprehensive data on BPA-induced disruption association and functional characteristics testicular germ cells, present study sought to investigate. Adult mice were administered BPA doses by gavage for six consecutive weeks allowed breed, producing generations F1–F4. Testis samples from each generation evaluated several parameters, including...
Abstract To explore Bangladesh's ability to detect novel influenza, we examined a series of laboratory-confirmed pandemic (H1N1) 2009 cases. During June–July 2009, event-based surveillance identified 30 case-patients (57% travelers); starting July 29, sentinel sites 252 (1% travelers). Surveillance facilitated response weeks before the spread infection general population.
Coronavirus disease 2019 (COVID-19) is a protean causing different degrees of clinical severity including fatality. In addition to humoral immunity, antigen-specific T cells may play critical role in defining the protective immune response against SARS-CoV-2, virus that causes this disease. As part longitudinal cohort study Bangladesh investigate B and cell-specific responses, we sought evaluate activation-induced marker (AIM) status cell subsets during COVID-19 infection. We analyzed total...
ABSTRACT Background: Recent nutritional interventions have targeted colonic functions in patients with infectious diarrhea during rehydration and recovery from malnutrition, the assumption that effects will be influenced by metabolism of complex carbohydrates bacteria. However, diversity bacteria cholera is not known. Aim: To study malnourished children before treatment oral salt solutions containing 1 these 3 substrates: glucose, rice, or amylase‐resistant starch. Patients Methods: Serial...
Exposure to bisphenol A (BPA) in the gestational period damages reproductive health of offspring; detailed evidence regarding BPA-induced damage testicular germ cells offspring is still limited. In this study, pregnant mice (F0) were gavaged with three BPA doses (50 μg, 5 mg, and 50 mg/kg body weight (bw)/day; tolerable daily intake (TDI), no-observed-adverse-effect-level (NOAEL), lowest-observed-adverse-effect level (LOAEL), respectively) on embryonic days 7 14, followed by investigation...
The longevity of immune responses induced by different degrees severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection provides information important to understanding protection against disease 2019 (COVID-19). Here, we report the persistence SARS-CoV-2 spike receptor-binding domain (RBD) specific antibodies and memory B cells recognizing this antigen in sequential samples from patients Bangladesh with asymptomatic, mild, moderate COVID-19 out six months following infection....
Many of the testicular cancer-survived patients, treated with chemotherapeutic drugs, show infertility, pre and postimplantation loss, germ cell abnormality. Studies examining negative effects drugs on cells are ongoing; however, information stemness properties proteomic profiles these lacking. This study investigated etoposide, cisplatin, bleomycin, their combination (BEP) physiology stem activity mouse in vitro. Our results showed that treatment abovementioned affected viability decreased...
Bone tissue engineering aims to repair diseased or damaged bone that cannot be regenerated naturally. This study is designed develop biodegradable porous scaffolds as substitutes and evaluate the effect of gamma irradiation on these for restoration defected bone. Here, composite (HA-COL-CS-Mg-ZnO) were prepared by thermally induced phase separation (TIPS) technique using collagen (COL) chitosan (CS), hydroxyapatite (HA), magnesium (Mg), zinc oxide (ZnO) at different mass ratios. Thereafter,...
Objectives: In recent years, green synthesis of silver nanoparticles (AgNPs) has gained much interest from researchers as biomedical treatments. The purpose this study was to determine if AgNPs synthesized Hibiscus Sabdariffa L. bark extract are an effective stabilizing agent and inhibit Ehrlich ascites carcinoma (EAC) cell growth. Methods: were prepared by the reaction 0.6mM nitrate 5% extract. Synthesis confirmed UV-visible spectroscopy well characterized scanning electron microscopy,...
Background: Since chemical anticancer drugs are found to have adverse effect on body, nowadays people motivated towards natural agents treat cancer. Fruits and vegetables potential source of that protect our body against cancer by scavenging neutralizing free radicals. Objective: The study was aimed explore antioxidant properties methanolic extract leaves Hibiscus sabdariffa L. (MEHSL). Methods: In vitro assays were used examine the different types phytochemical content MEHSL. in vivo...
The development of biocompatible scaffolds is rapidly growing in several fields human health, particularly for the treatment bone defects. In this study, silver nanoparticle (AgNPs)-incorporated hydroxyapatite (HA), chitosan (Chi), and polyvinylpyrrolidone (PVP)-based were fabricated using freeze-drying method tissue engineering. Physicochemical properties such as porosity, density, swelling ratio, biodegradability, well blood biocompatibility, brine shrimp lethality, antibacterial...
