Weens goeie algemene gesondheid kom die adolessent dikwels nie met die gesondheidsorgstelsel in aanraking nie. Adolessente het egter baie gesondheidsvoorligtingsbehoeftes waaraan daar nie voldoen word nie. Adolessente het verskeie volwassewordingstake om te verrig en ten opsigte van hul voorligtingsbehoeftes moet die mens as geheel, asook sy omgewing, in ag geneem word. Daarom behoort voorligti...

Plankton communities and macrofauna associated to aquatic macrophyte stands in a shallow water-supply reservoir (21°14'09″S; 48°18'38″W) on an aquaculture farm were compared to evaluate the relationship between organism densities and some abiotic features of the reservoir. Water and communities associated were sampled at two sites, one in an area with the predominance of Eichhornia azurea (Sw.)...

To investigate the cytotoxic effect of some Bangladeshi medicinal plant extracts, 16 Bangladeshi medicinal plants were successively extracted with n-hexane, dichloromethane, methanol and water. The methanolic and aqueous extracts were screened for cytotoxic activity against healthy mouse fibroblasts (NIH3T3) and three human cancer-cell lines (gastric: AGS; colon: HT-29; and breast: MDA-MB-435S)...

Plants produce a wide variety of phytochemical constituents, which are secondary metabolites and are used either directly or indirectly in the pharmaceutical industry. 'For centuries, man has effectively used various components of plants or their extracts for the treatment of many diseases, including bacterial infections. In the present study methanol, chloroform and aqueous extracts of Cassia ...

OBJECTIVES To evaluate the antioxidant potential of porridges (kola kenda) made incorporating herbs. DESIGN Experimental study. Main outcome measures Total phenolic content was estimated by Folin Ciocalteau method (GAEmg/g(FW) and the antioxidant potential by ABTS free radical scavenging activity (TEAC(μg)/100g (FW). RESULTS Total phenolics and antioxidant potentials of porridges ranged fro...

Screened plant species with potential for green belt development can act as eco-sustainable tools restoring the polluted ecosystem. Eight from two study locations in Ado-Odo, Ota, Ogun State, Nigeria, were examined to identify their air pollution response and performance by deploying indices, namely tolerance index (APTI) anticipated (API). APTI results identified all screened plants sensitive ...

In this paper, we prove an equivariant version of the classical Dold-Thom theorem. Let G be a finite group, X a G-space, and k a covariant coefficient system on G. We construct a topological abelian group GX ⊗ G k by the coend construction. We then prove that for a G-CW complex X, πi(GX⊗ B G k) ∼= H i (X; k), where the right hand side is the Bredon equivariant homology of X with coefficients in...
