Drosophila melanogaster serves as an important research model organism in the fields of genetics and developmental biology. Recent studies have indicated the use of Drosophila in a number of other studies such as metabolic, nanotoxicological and immunological studies. Rearing of fly in the laboratory condition is an important task to work with this organism. To maintain the growth and development of the flies where the components of the food play important roles, this is done by mixing the compounds with fly food in proper concentration.

Occupational exposure to bronze borne toxicant is entirely unregulated in many countries. The foundry industry is known to contain a lot of toxic metals and the exposure of foundry workers to these metals may result in prooxidant/antioxidant imbalance and can act as an intermediate in the formation of an oxidative stress state. This aim of this study was to investigate the levels of total antioxidant capacity, malondialdehyde and C-reactive protein among bronze foundry workers in Benin City, South-South Nigeria.

Helicobacter pylori is a Gram-negative microaerophilic bacteria with a spiral (helical) morphology which is usually found in the stomach. H. pylori infection is one of the most common bacterial infection worldwide and in children of lower ages. Reports show that this bacterium is associated with simple dyspepsia, heartburn and peptic ulcer diseases, most commonly leading to upper gastrointestinal bleeding and ultimately to the severe compilation of gastric malignancy. Diabetes mellitus is an important factor that increases the susceptibility and risk of various infections in the host.

Today, occupational exposure to harmful substances is common in many nations across the globe. This occupational exposure in many countries is highly unregulated. Using the bronze casting industry as a case study, there is a heightened interest in bronze artwork but its creators (bronze casters) haven't been given much thought when it comes to exposure to toxicants. Bronze casting can result in exposure to harmful material into the body and this can have an impact on reproductive health.

Actinomycetes are threadlike or filamentous, Gram positive bacteria that form branching filaments with hyphae and asexual spores. The hyphae are usually septate or coenocytic in nature. The aim of this study was to investigate the microbial ecological distribution of marine actinomycetes isolated from the Lagos Atlantic Ocean, South West Nigeria. Marine (soil and water) samples were collected from about 10 m deep from Lagos Lagoon and Atlantic Ocean. Starch Casein agar was prepared aseptically.

The workforce in sub-Saharan Africa faces stressful conditions while commuting on the road and while at 

Estrogen and Progesterone are two major hormones of pregnancy. As soon as a spermatozoon fertilizes an ovum, hormonal changes begin in preparation for implantation and subsequent maintenance of pregnancy. The aim of the study was to determine if there are changes in Estrogen/Progesterone ratios (E/P) during pregnancy in different trimesters of pregnancy in Wistar rats. Twenty female Wistar rats were categorized into four different groups of five rats each. Group one (non-pregnant rats) served as the control.

Dumpsite utilization for municipal solid waste disposal produces leachate which is a threat to groundwater resources. The study was aimed at determining the suitability of groundwater for drinking and domestic usages using physical, chemical and microbial indices, with a view to assessing the vulnerability of boreholes close to dumpsite to groundwater pollution. The results showed that except for pH and lead, the concentrations of other physico – chemical parameters were within acceptable limits of NSDWQ and WHO.

Cisplatin is an established chemotherapeutic substance commonly used in the treatment of cancer. This study was conducted to examine the possible counter effects of Human Menopausal Gonadotropins (HMG) against testicular toxicity induced by Cisplatin in male rats. 20 adult male rats were equally divided into four groups; A, B, C and D which were the control, Cisplatin, HMG and Cisplatin+HMG groups respectively.

This investigation was undertaken to examine the phytochemicals in the leaves of sour soup harvested from five States of Nigeria. Standard methods for the quantitative assessment of the phytochemicals were adopted in the analysis. Results obtained indicated that the phytochemicals were in varied concentrations in the leaves from each of the States. The range of the concentration of alkaloid, tannin, flavonoid, saponin, phytate, steroid, phenol and oxalate were 4.08-2.11%, 30.20-10.50%, 1.52- 0.61%, 1.66-0.69%, 0.16-0.08%, 3.80-3.20%, 3.60–3.19% and 0.26–0.24% respectively.
