To determine the effect of light and dark on callus induction and plant regeneration from five different explants of three tobacco varieties were studied. Normal white light (3000 lux) and dark conditions were considered for callus induction. Among the explants earliest callusing initiated at 5th da...

Inorganic arsenic (InAs) is metabolized through a series of methylation reactions catalyzed by arsenic(III)-methyltransferase (AS3MT), resulting in the generation of monomethylarsonic (MMAs) and dimethylarsinic acids (DMAs). AS3MT activity requires the presence of the methyl donor S-adenosylmethioni...

Oxidative stress and DNA methylation are metabolically linked through the relationship between one-carbon metabolism and the transsulfuration pathway, but possible modulating effects of oxidative stress on DNA methylation have not been extensively studied in humans. Enzymes involved in DNA methylati...

Abstract Background: Posttranslational histone modifications (PTHMs) are altered by arsenic, an environmental carcinogen. PTHMs are also influenced by nutritional methyl donors involved in one-carbon metabolism (OCM), which may protect against epigenetic dysregulation. Methods: We measured global le...

Three Bangladeshi barley genotypes viz. BARI barley?1, 3 and 6 were selected for this study to evaluate the efficiency of callus induction and plant regeneration. The effect of five doses of AgNO3 singly, and combined with amino acids (Lproline, L?glutamine) on callus induction and plant regeneratio...

BACKGROUND: Chronic exposure to well water arsenic (As) remains a major rural health challenge in Bangladesh and some other developing countries. Many mitigation programs have been implemented to reduce As exposure, although evaluation studies for these efforts are rare in the literature. OBJECTIVES...

BACKGROUND: Essential tremor (ET) is one of the most common neurological diseases. Few prevalence studies have been conducted in South Asia, and none in Bangladesh, one of the most populated countries in the world. We estimated the prevalence of ET in a population-based study in Araihazar, Banglades...

Background Millions of villagers in Bangladesh remain exposed to high levels of arsenic (As) from drinking untreated well-water even though the scale of the problem was recognized 15years ago. Water treatment at the household-level has been promoted as a viable complement but few longitudinal studie...

Hepatitis C virus (HCV) is a leading cause of chronic liver disease worldwide also in Bangladesh. Prevalence of Hepatitis C virus infection in rural adult population of Bangladesh is reported to be 0.6% but the exact pattern of existing genotype has not been well studied. Genotyping of HCV is import...
