Aqueous Root Extract of Piliostigma thonningii Modulates the Activities of Antioxidant Enzymes and Lipid Levels in Paracetamol-Induced Damage in Rabbits

Paracetamol is notorious for causing liver damage due to excessive generation of free radicals due to overdose ingestion. The body has an antioxidant system comprising enzymes and non-enzymes, which help to mop up free radicals generated.

The Proximate and Phytochemical Analyses of Aqueous Root Extract of Piliostigma thonningii and its Effects on Indices of Well-being in Experimental Animals

Plants have constituted a significant quota to the sustainability of humans as food, medicines and raw materials for other uses. Increased awareness of the significance of medicinal plants led to more studies focused on the phytochemistry and proximate analysis of plants.

Analysis of Hematological Indices and Serum Immunoglobulin Levels (IgG and IgM) in Preeclamptic and Normotensive Pregnancies

 Preeclampsia (PE) is a common complication during pregnancy, affecting 2–5% of pregnant women. It is believed to be associated with modulaton of immune response. This study investigated some hematological indices and serum levels of immunoglobulins- Ig G and IgM in pre-eclamptic and normotensive patients attending Ante-natal Clinic at the University of Benin Teaching Hospital Benin City, Nigeria.

Testes Histo-Morphological Changes in Laboratory Rats, Rattus norvegicus, Exposed to Various Spectral of Artificial Light at Night (ALAN)

Exposure to various spectral of light at night is presently inevitable, hence the need to examine its spectral effect on male reproductive function. This study aimed at evaluating the periodical change in testicular histomorphology of albino rats exposed to various lights spectral {Blue (BL), Green (GL), Yellow (YL), Red (RL), and White (WL)} at night for 126 days. Compact fluorescence bulbs, 11 watts, maintained at 300 Lux, were used.

Assessment of Microplastics in Water, Sediment, and Fish of Ikpoba Rivers of Edo State, Nigeria

This study presents a comprehensive assessment of microplastics in water, sediment, and fish species (Clarias gariepinus and Oreochromis niloticus) of the Ikpoba River. Water samples were collected using twenty-five-litre stainless steel buckets, sediment samples were obtained using a Van Veen grab sampler, and fish samples were collected using gill nets and hand nets respectively.

Heavy Metal Concentration and Physicochemical Changes of Soil Treated with Spent Engine Oil and Organic Manure (Poultry) After 12 Weeks of Growing Cyperus compressus L.

ABSTRACT: Heavy metal concentration and physicochemical changes of soil treated with spent engine oil (SEO) and poultry manure after 12 weeks of growing Cyperus compressus was this study’s aim. Poultry manure (PM) was 10 % of 4000g (400 g) while the soil was 3600 g.

Comparative Preservative Potential of Shea Butter and Coconut Oil on Tomato Fruits (Solanum lycopersicum)

Tomato fruits are perishable. Hence several methods have been adopted in their preservation which have not been generally accepted due to their health implications. Therefore, the aim of this study is to investigate the potential of coconut oil and sheabutter in the preservation of tomato fruits. Tomato fruits were washed and treated with coconut oil and shea butter which was varied at different concentrations of 3, 6, 9, 12 and 15 % (w/v).

Assessment of Plant-Pathogenic Fungi in Anthill Soils

 This study aimed at assessing the presence of plant pathogenic fungi in soil samples collected from the immediate vicinities of anthill mounds and adjacent areas. Soil samples were collected from anthill mound and their corresponding adjacent soils, from four sites located in Ekosodin and Ugbowo respectively with both locations sited in Benin City, Nigeria. Enumeration, characterization and identification of fungal isolates were done using standard mycological methods.

Prevalence of Enterobacteriaceae in Fresh Vegetables Sold in Open Markets in Benin City Nigeria

Vegetables are good sources of nutrients and can be contaminated by bacteria thereby causing spoilage and food-borne illnesses. The aim of this study was to determine the prevalence of Enterobacteriaceae in fresh vegetables sold in open markets in Benin City, Edo State. Thirty fresh vegetables samples comprising of scent, utazi, uziza, pumpkin and okazi leaves were obtained from three open markets. Isolation was carried out using pour plate technique and isolates were identified based on cultural, morphological and biochemical characteristics.
