This study is to determine the effect of wastewater disposal from the Warri Refinery and Petrochemical Company (WRPC) on the DNA integrity in the African catfish, Clarias gariepinus juveniles exposed to 1, 10, 20 and 30 % (v/v) of the wastewater.
Untreated and improperly treated industrial effluents endanger the aquatic fauna of the receiving water bodies, making the appropriate monitoring of the effluent discharges from industrial facilities of utmost importance. The potential ecological impact of the effluent from a glass manufacturing facility was investigated using the African catfish (Clarias gariepinus).
The GC-MS analysis of the volatile constituents of crude honey residue (VCHR) and its in vitro antioxidant study of the crude honey residue (CHR) has been carried out. Hydrodistillation technique was employed in the extraction of the VCHR. The various candidates present in the extract of crude honey residue (ECHR) were identified using the gas chromatography-mass spectrometry (GC-MS) instrumental method of analysis. The ECHR was investigated for in vitro antioxidant study by exploring the free radical scavenging potential via the 2,2- diphenyl-1- picrylhydrazyl, DPPH technique.
Erectile dysfunction (ED) has posed problems among several married couples. This study evaluated the efficacy of combined ethanol root extracts of Terminalia avicennioides, Terminalia superba and seeds of Hunteria umbellata on Paroxetine-induced erectile dysfunction in male Wistar rats. Fresh roots of plants were collected, pulverized, extracted with 70% ethanol, dried in an oven at 400C and subjected to phytochemical screening. The plants were mixed in a ratio of 1:1:1; T. superba and T. avicennioides (TASM) mixed; T. superba, T. avicennioides and H. umbellata (TASHM) mixed.
this study is aimed at assessing the in-vitro effect of Aframomum daniellii seed extract, Aloe vera gel, Gongronema Latifolium leaf extract, Monodora myristica seed extract and honey on Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Candida albicans. Agar well diffusion method was used for the susceptibility test. The plates were incubated at 37 oC for 24 h. Extracts and diameter zones of inhibition were measured. All test organisms were susceptible to honey and Aloe vera gel, and a combination of both honey and Aloe vera gel.
This study assessed heavy metals (HMs) contamination in road dust using geochemical indices and their potential risks from an urban environment in Delta State, Nigeria. Fifteen road dust samples were sampled, digested in aqua regia and their HMs concentrations determined using atomic absorption spectrometry.
Tomato as vegetable and regarded as protective food is a very significant food crop globally. In this study, lycopene present in tomato and known for its anti-oxidative ability was correlated with fruit yield. Three varieties of tomato were selected and their growth rates were compared by measuring the length (cm) of stem from the day of transplanting till maturity (at flowering), on weekly basis. The three tomato varieties identified as Igb1/9/21, Igb2/9/21 and Igb3/9/21 were not significantly different in their growth.
The efficacy of methanol leaf extract of Jatropha curcas was investigated through in-vitro assay against Trypanosoma brucei-brucei in 96 well micro-titer plates. Maceration method was used to obtain the leaf extract using absolute methanol.
The ecology and growth of the shellfish, Tympanotonus fuscatus was studied in a mangrove swamp of the Warri River, Abiotic and Biotic factors such as temperature, salinity, hydrogen ion concentration, nature of substrate, associated fauna and flora, micro – habitat were investigated. Weight/Length relationship of the shellfish was measured to determine the growth rate. Results showed a low range (27.5°C – 31.0°C) in temperature variation and high range (0.3% - 7.1%) in salinity variation, while pH values were between 6.5 – 7.8.
Investigations into the seasonality of cyclopoid (crustacean: copepoda) with regards to rainfall variations were carried out in Forcados river. Samples were collected by towing two plankton nets of 55µm and 100µm mush sizes at 5knots for 5 minutes behind an engine boat. Meterological station in Warri gave the rainfall data. Centigrade thermometer was used for measuring the surface water temperature. Results showed low temperature range (27.5ºC – 31.5ºC), while that of rainfall was high (25.8-602.6mm).
