Antiplasmodial activity and cytotoxicity of ethanol extract of root.

Objective: root decoction that has been traditionally used for the treatment of malaria by various tribes in Nigeria, was evaluated for antimalarial potential against malaria parasites using and models.

Materials And Methods: The root extract of was investigated for antimalarial activity against in mice using rodent malaria models; suppressive, prophylactic and curative tests and antiplasmodial activity against chloroquine-sensitive (Pf 3D7) and resistant (Pf INDO) strains of using SYBR green assay method. Median lethal dose and cytotoxic activity against HeLa and HEKS cells were assessed and phytochemical screening was also carried out using standard procedures.

Enhancing an International Perspective in Public Health Teaching through Formalized University Partnerships.

Teaching in the field of public health needs to employ a global perspective to account for the fact that public health problems and solutions have global determinants and implications as well. International university partnerships can promote such a perspective through the strengthening of cooperation, exchange, and communication between academic institutions across national boundaries. As an example for such an academic network in the field of public health, we introduce the International Public Health Partnership-a collaboration between a university in Germany and universities in India, Turkey, and Nigeria.

Antimalarial and antiplasmodial activity of husk extract and fractions of Zea mays.

Context: Zea mays L. (Poacae) husk decoctions are traditionally used in the treatment of malaria by various tribes in Nigeria.

Objective: To assess the antimalarial and antiplasmodial potentials of the husk extract and fractions on malaria parasites using in vivo and in vitro models.

Polycyclic aromatic hydrocarbons loads and potential risks in freshwater ecosystem of the Ikpa River Basin, Niger Delta-Nigeria.

In this study, the levels of 16 USEPA-prioritized polycyclic aromatic hydrocarbons (PAHs) were quantified in various environmental matrices in Ikpa River Basin and nearby dumpsites using gas chromatography-mass spectrometry (GC-MS). The levels of the contaminants were further subjected to models to estimate possible sources and potential risks. The results obtained revealed that nearby dumpsites could be the major source of contamination of the Ikpa River Basin.

Nutrient Composition and In Vitro Antioxidant Properties of Harungana madagascariensis Stembark Extracts.

The stembarks of Harungana madagascariensis were analyzed for their content of chemical constituents, antinutrients, vitamin levels, and in vitro antioxidant properties in two solvent systems. Phytochemical screening revealed higher levels of alkaloids, saponins, and flavonoids in the methanolic (MHM) extract than in the dichloromethane (DCM) extract. The methanolic extract had higher contents of minerals, vitamins, and antinutrients except K, vitamin B1, and phytic acid, respectively.
