Ethnocentrism: Significance and effects on Kenyan society

African Journal of Political Science and International Relations

Afr. J. Pol. Sci. Int. Relat.

This study investigates the significance and effects of ethnocentrism in the Kenyan society. The usual concept of ethnocentrism combines the belief that one’s culture is superior to other cultures with the practice of judging other cultures as inferior to one’s own culture. This concept does not address the underlying issue of why people do this but emphasizes that people make false assumptions based on their own limited experience about... Read more

International Journal of Nutrition and Metabolism

Int. J. Nutr. Metab.

Njangsa (Ricinodendron heudelotii), a tropical tree that grows in the forest of West and Central Africa, produces fruits that are manually shelled to collect oil seeds and dried. A compositional analysis of njangsa revealed a unique nutrient presence of long chain omega-3 fatty acids not usually associated with plant materials. The seed had 31.4% crude protein and 44.7% lipid. Of this lipid, about 73% was composed of polyunsaturated fatty acids... Read more

In vivo antimalarial activity of the crude extract and solvent fractions of the leaves of Zehenria scabra (Cucurbitaceae) against Plasmodium berghei in mice

Journal of Medicinal Plants Research

J. Med. Plants Res.

Zehenria scabra is among the Ethiopian folk medicine for malaria like fever and other infectious diseases. But it lacks apposite pharmacological investigation. This study aimed at evaluating the antimalarial activity and safety profile of Z. scabra. Plasmodium berghei was used for induction of malaria, kept in a refrigerator and maintained by serial passage of blood from mouse to mouse. The crude extract, chloroform and ethylacetate fractions were... Read more

Chitinolytic assay for Trichoderma species isolated from different geographical locations of Uttar Pradesh

African Journal of Biotechnology

Afr. J. Biotechnol.

Chitin is the most commonly available polymer on the earth. Cell walls of most of the fungi are made up of chitin. As we all know that Trichoderma produces a wide variety of cell wall degrading enzymes (CWDEs) such as chitinase, xylanase, glucanase and cellulase. Out of these CWDEs chitinase is of prime importance as it is the building block of fungal cell walls. For the detection of chitinase activity we used a simple and sensitive method. We... Read more
