    Drastic deforestation is a major problem of Bangladesh which is contributing to negative downstream impacts on the environment. To address this problem various measurements should be taken at different scales. The main objective of this study is to suggest the possible steps that Bangladesh could halt and reverse the trend of deforestation. An extensive literature review and interviews with government officials, professionals and NGO workers have been used to collect relevant information on the drivers of deforestation in the country. Based on the information gathered, this paper presents the reasons and extent of deforestation, and suggests some positive steps where the Government could be the main mitigating performer by implementing integrated programmes, which will also ensure mass awareness and wider impact. Local NGOs and international bodies must also formulate adequate plans to protect valuable areas of remaining forest.DOI: 10.3126/on.v8i1.4340

    Background: Like other sexually transmitted diseases (STD), ano-genital warts (AGW) is associated with human immunodeficiency virus (HIV) infection and this study of AGW was conducted among HIV positive and HIV negative patients. The aim of the study was to study the risk factors and clinical presentations of ano-genital warts in HIV infected patients.Methods: A comparative, cross-sectional, descriptive study of 25 HIV positive and 25 HIV negative (n=50) AGW patients between 15-60 years of both sex was conducted in Northern part of Bangladesh from July 2015 to December 2016.  Results: Significant association of HIV positivity (p<0.05) was observed between age group of 15-30 years and HIV negative status (p<0.05) in age group of 31-45 years. HIV positive status significantly higher in patients with self-admitted multiple sexual partners (p<0.01), homosexuality (p<0.05) and presentation with anal warts (p<0.01). HIV negative status correlated significantly with single s...

    In the present investigation, two species of oyster mushroom (Pleurotus hiking and Pleurotus ostreatus) were analyzed for nutritional values (carbohydrate, protein, vit-B2, vit-C, β-carotene, lycopene, ash, moisture and minerals concentration) and antioxidant activities. The research showed significantly different results for most of the parameters studied. Between the two oyster mushrooms P. hiking contained the higher concentration of protein, ash, calcium (Ca), zinc (Zn) and iron (Fe) than P.ostreatus. On the other hand, P. ostreatus contained the higher amount of carbohydrate, vit-B2, vit-C, total moisture and manganese (Mn) content as well as pleasing antioxidant activities than P. hiking. The concentration of β-carotene and lycopene were found very negligible in both the species. The findings also showed that the studied oyster mushrooms may be used not only as an admirable nutritious dietary food but also unobjectionable pharmaceutically significant with high antioxidant.
    Resumen en: The systematic and genetic relationship among different species of Pleurotus mushrooms is still unclear. Because of that, 20 strains of Pleurotus spp. co...
