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.

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.

Sub-acute Toxicity Assessment of Methanol Leaf Extract of Polyalthia longifolia (Sonn.) Thwaites on Haematological and In Vivo Antioxidant Parameters in Wistar Rats

Polyalthia longifolia is an ornamental plant, which has been reported to possess various ethnomedicinal applications. However, there is a dearth of information on the toxicity profile in the administration of the plant extract. The study evaluates the impact of sub-acute administration of methanol leaf extract of P.

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).

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 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.

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.

Effects of Black Seed Oil on Oxidative Stress Parameters and Gingival Expression of Inducible Nitric Oxide Synthase in Diabetes and Periodontitis-Induced Rats

Using diabetic and periodontitis-induced rats, the effects of black seed oil on oxidative stress parameters and gingival expression of inducible nitric oxide synthase were examined in this study. Eight groups of forty eight were created. Rats from Group I were used as the Control group; they had unrestricted access to typical rat diet and were not given any medications. NS oil was given to the rats in group II in addition to their standard rat chow and water. In Group III animals, diabetes was induced without treatment.

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.
