In vitro antioxidant and antiglycation studies on african mistletoe (T. bangwensis (Engler and K. Krause), Danser) and ring worm plant (S. alata (Linn.) Roxb) from Nigeria
The antioxidant activity of crude methanolic extracts and fractions of African mistletoe (Tapinanthus bangwensis) and Ring worm plant (Senna alata) leaves from Nigeria was investigated. In an in vitro free radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH), superoxide scavenging (SOS) activity and chelation of iron (II) ion [Fe2+] in the presence of ethylenediaminetetraacetic acid (EDTA), ethyl […]

Organochlorine pesticide residues analysis of postharvest cereal grains in Nasarawa State, Nigeria
The study investigated the levels of organochlorine pesticide (OCPs) residues in post harvest grains in Nasarawa State-Nigeria. Millet, guinea corn and maize grains were collected from major markets in the study area, prepared and analyzed for organochlorine pesticides using gas chromatography. The result indicated the presence of varying amounts of ten (10) organochlorine pesticide residues […]
Impact of crude oil pollution on the physicochemical and microbiological properties of orashi river wetland in Egbema, Nigeria
The study investigated impact of crude oil pollution on the physicochemical and microbiological parameters of crude oil polluted Orashi River wetland. The physicochemical, microbiological parameters and trend of enzymatic activities in crude oil polluted and unpolluted wetlands were evaluated. Bioloads had their highest values in the lightly polluted wetlands with values of rainy season leading, […]
Heavy metal bioaccumulation of selected tuber crops from Ishiagu, Ebonyi State, South East, Nigeria
Heavy metal concentration of soil and selected root crops cassava, yam, cocoyam and potato from three mining areas of Ishiagu, Ebonyi State were Evaluated. Heavy metals were analysed using Atomic absorption spectrophotometer (AAS). Results showed that lead (Pb) concentration of soil samples raged from 1.12±0.01a – 2.05±0.01c, Cadmium 0.46±0.02a – 0.77±0.01b, Chromuim 0.97±0.03d – 1.23± […]
The prevalence of extended spectrum beta-lactamases (ESBLs) among Escherichia coli and Klebsiella species urinary isolates from Abia state university teaching hospital (ABSUTH) aba, Abia State Nigeria
The prevalence of extended spectrum β-lactamases among 246 clinical isolates from Abia State University teaching Hospital patients was investigated. The isolates were made up of 134 Escherichia coli and 112 Klebsiella species. Antimicrobial susceptibility of the isolates was determined by the disc diffusion method. ESBL phenotypes were determined by the double disc synergy method using […]
Groundwater quality assessment in a major livestock feedlot/abattoir (imowo-eleran) in Ijebu-ode, Ogun state, Southwestern Nigeria
This study assessed the quality of groundwater in Imowo-eleran, a major livestock feedlot/abattoir in Ijebu-Ode, Ogun state, southwestern Nigeria. A total of twelve (12) boreholes, grouped into A, B and C in relation to proximity to the feedlot were assessed using physico-chemical and bacteriological parameters. On-site observation and organoleptic properties of appearance, colour, odour and […]
