The study was carried out with the aim to determine the antimicrobial effect of ethanolic leaf extract of  Mitracarpus scaber against some clinical isolates. The leaves were screened for some phytocompounds using standard  analytical methods.The antimicrobial activity of the leaf extract against Escherichia coli, Staphylococcus aureus and Candida albicans was carried out using agar well diffusion and broth dilution methods. The results of phytochemical studies revealed the presence of alkaloids, flavonoids, cardiac glycosides, triterpenes, phytosterols, tannins, and saponins.

The present study explored the use of anatomical characters of Sataria barbata and Brachiaria deflexia as indicators of waste engine oil pollution. Four (4) kg of air dried soil was measured into perforated plastic buckets and treated with waste engine oil to obtain different concentrations [0% (control), 2%, 4%, 7% and 10%] on volume to weight basis.The experiment was set up in 3 replicates. The soil samples were allowed to stand for seven days before seedlings were planted. The plants were harvested after 8 weeks of transplanting.

This study was carried out to determine the bacterial and fungal flora of soils contaminated with used automobile engine oil at a mechanic workshop at AKAD community, Akure, Ondo State, Nigeria, with the aim of testing  their ability to degrade diesel oil. Isolation and identification of microbes were done using standard microbiological techniques. Oil degrading activity of the isolates were assayed for using Bushnell Haas broth (BHB) supplemented with 1% diesel oil.

The major problem in Cola propagation is related to seed germination and slow growth rate, hence this study was designed to ascertain the effect of soil types and mechanical scarification on the germination and seedling growth of Cola nitida. The experiment was a two factored experiment of 4 soil type (Topsoil, topsoil combined with carbonized sawdust (TSCSD), topsoil combined with river soil (TSRS) and River soil) and 2 scarification (Nicked and Whole seed) laid in a Completely Randomized Design (CRD) with 3 replicates.

The study was conducted to investigate the effect of different concentrations of ethyl methanesulfonate (EMS) on the growth and yield of two okra (Abelmoschus esculentus L. Moench) varieties (V35 and Clemson spineless). The experiment was conducted in the screen house and field at Michael Okpara University of Agriculture, Umudike, Abia State. The screen house experiment was set up in a complete randomized design (CRD) with three replications. The field trial was set up in randomized complete block design (RCBD) with three replications.

In the present study, seeds of Pigeon pea (Cajanus cajan L. Millspaugh) accessions (Brown and Cream colours) were treated with different concentrations of Ethyl methane sulphonate (0.0 %, 0.01 %, 0.02 %, 0.03 %, 0.04 %, 0.05 %, 0.06 % and 0.07 %). The seeds were sown and monitored for 30 days. Data obtained showed a trendy effect. Data obtained showed that germination percentage was decreased with an increase in the mutagen concentration when compared with the control.

 The study was a 2-arm individually randomized clinical trial conducted at the Nigeria Institute of Medical Research (NIMR) in Lagos, Nigeria, aimed to improve the overall patient adherence to tuberculosis treatment using Video Observed Therapy (VOT). A total of 100 participants were recruited to this study. Data was collected through the NimCure mobile app and patient records. Results obtained showed a high rate of at least 90% adherence to TB treatment was achieved in both VOT and DOT groups.

Two aquarium tanks labelled A and B were each half filled with water. They were kept open outside the laboratory for seven days so that mosquito larvae will develop in them. Then plankton samples were collected from Ikpoba dam with two plankton nets of 55µm and 100µm mesh sizes. Copepod species were sorted out from the plankton samples and poured into tank A, while tank B was left alone as control. The two tanks were examined after five days. Results showed that the copepod species have eaten up all the mosquito larvae in tank A while in tank B, mosquito larvae were seen in abundance.

The concentration, distribution and sources of petroleum hydrocarbons in soils from selected areas in  Abraka, Delta State, were evaluated. Soil samples were collected from areas suspected to be contaminated with  petroleum hydrocarbons, which were also in proximity to human population. These areas included busy junctions, generator maintenance workshops, suya joint, drainage and fuel stations. Samples were extracted using nhexane/dichloromethane mixture and quantified using gas chromatograph-flame ionization detector.

Reducing sugar is a sugar that serves as a reducing agent. It falls under the category of carbohydrate or natural sugar but it consist of either a free aldehyde group (-CHO) or a ketone groups called the reducing end of the sugar. Microbial growth describes an increase in cell number of microorganisms provided with suitable nutritional and environmental conditions.
