Several medicinal plants have been documented for their haematological effects either at low or high concentration but very little is known about Aspilia africana. The aim of the study was to investigate the acute effects of aqueous leaf extract of Aspilia africana at different concentrations on some haematological parameters in rats. Following 14 days of oral administration of aqueous extract ...

The study was carried out to investigate the central nervous system activity of Treculia africana. The central nervous system depressant properties of Treculia africana were determined using: Novelty –Induced Rearing and Grooming, Locomotor activity, Ketamine-induced sleeping time and effect on rectal body temperature. The crude extract produced decrease in rearing, grooming and locomotor activ...

Background: Many older African Americans perceive “spirituality” as an important resource in helping with the self-management process of their chronic conditions. Research designs congruent with theoretical frameworks of African Americans are important. However, many researchers remain unfamiliar with Africana womanist thought or are unsure as to how this framework can be used to inform specifi...

Stemmadenia tomentosa var. palmeri, Voacanga africana, Apocynaceae, Cell Suspension Cultures, Indole Alkaloids Cell suspension cultures of Stemmadenia tomentosa synthesized under normal growth condition the eight major indole alkaloids: (-)-tabersonine, (—)-minovincinine, (+)-conoflorine (voaphylline), condylocarpine, (+)-tubotaiwine (dihydrocondylocarpine), (-)-norfluorocurarine (vincanine), (...

Skinner and colleagues (Research Article, 23 January 2015, p. 395), based on metacarpal trabecular bone structure, argue that Australopithecus africanus employed human-like dexterity for stone tool making and use 3 million years ago. However, their evolutionary and biological assumptions are misinformed, failing to refute the previously existing hypothesis that human-like manipulation preceded ...

Poaching has devastated forest elephant populations (Loxodonta cyclotis), and their habitat is dramatically changing. The long-term effects of poaching and other anthropogenic threats have been well studied in savannah elephants (Loxodonta africana), but the impacts of these changes for Central Africa's forest elephants have not been discussed. We examined potential repercussions of these threa...
