Characterization and Evaluation of Different Extracts from the Leaf and Bark of Mussaenda glabrata Hutch.
Abstract: β-sitosterol (1) was isolated from the crude extract of the leaf of Mussaenda glabrata Hutch. (Family: Rubiaceae). The petroleum ether, chloroform and methanol extracts of the leaf and bark were screened in vitro for cytotoxic and antimicrobial activities by brine shrimp lethality bioassay and disc diffusion method, respectively. The petroleum ether and methanol extracts of the bark showed potential cytotoxic activity (LC50: 2.51 µg/ml and 2.94 µg/ml, respectively), the petroleum …

Chemotaxis: role in egg-sperm interaction and its evaluation
Abstract: Communication between spermatozoa and egg before contact by chemotaxis is prevalent throughout the animal kingdom. In most animal species, the prospects of the spermatozoa coming in contact with eggs are very slim in the absence of some guidance mechanism usually chemical in nature that has been acquired gradually. Such chemical guidance, sperm chemotaxis, is now recognized in many marine invertebrates, fish, amphibians, and a few mammals including humans. This suggests …

Evaluating Building Density Analysis Using Geographical Information System
Abstract: In Mekelle city, urban sprawl is continuously expanding to the surrounding hinterland at an alarming rate without considering the inner infill area of the city. Moreover, several numbers of developers and land speculator hold large tract of vacant land. This has resulted because land speculators buy large aggregation lands and develop small part of their plot and keep the land until the price rises up. And this creates low density …
