The effect of hydro-alcoholic extract from Withania somnifera roots was studied on cell proliferation and apoptosis in Vero cells. Cell cytotoxicity assay using MTT dye reduction test found that there was increase in cell proliferation inhibition in a dose dependent manner. Higher the dose of the extract, higher was the cell proliferation inhibition. Fluorescent microscopy unraveled uniformly green appearance of normal cells and apoptotic cells stained orange with condensed chromatin, fragmented nuclei and presence of apoptotic bodies. The current work concluded that the extract of Withania...

The Jaldi and Maiskhali structures include a part of coastal region of north-south trending Fold Belt of Bangladesh, offers an excellent site for studies of soil-geomorphic relationships of undulating coastal regions. Based on the degree of soil development and luminescence dating of soils eight soil-geomorphic units have been delineated in the area and a four member (I IV) Morphostratigraphic sequence for the study area has been prepared with Member IV being the oldest. Sea level fluctuated several times with some stillstands during the late Quaternary Period. Eustatic stillstands may have...
