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.

Antimalarial Activity of Extracts and Partially Purified Fractions of Alstonia boonei De Wild

Alstonia boonei De wild is famed for several bioactive properties; this study measures its in vivo antimalarial potentials as well as phytochemical, nutritional and antioxidant properties. Variants of its stem bark extract were screened for phytochemical, nutritional and antioxidant properties using established procedures.

Antifungal Activity of Neem (Azadirachta indica) Leaf Extract against Pathogens Associated with Tomato (Solanum lycopersicum L.) Fruit Spoilage

The study was conducted to evaluate the antimicrobial activity of neem (Azadirachta indica) leaf extract against fungal phytopathogens isolated from diseased tomato (Lycopersicum esculentum) fruit. Diseased tomato fruits were obtained and to establish a mixed culture. Two distinctive fungi were identified on the mixed cultures and subculture into freshly prepared potato dextrose agar medium.

Production of Carboxymethyl Cellulose (CMC) From Rubber Seed (Hevea brasiliensis) Shells

Carboxymethyl cellulose (CMC) is a cellulose derivative utilized as a thickener in food processing, as well as in non-food items including paints and detergents. In this study, CMC was produced from cellulose which was obtained from rubber seed shells (RSS).  The CMC was produced from cellulose by mercerization with 30% sodium hydroxide (NaOH) solution and etherified using monochloroacetic acid. Fourier transform infra-red (FTIR) spectroscopy was used to characterize the CMC produced therein. The amount of cellulose extracted from RSS was 55.15 %.
