This study investigated the antidyslipidemic activities of the aqueous extract of Petiveria alliaceae leaves against high fructose-induced metabolic syndrome in male wistar rats. Forty-five male Wistar rats were randomized into two groups of control (n =15) and high fructose diet (n = 30) , each group received water and control diet and fructose enriched diet and water ad- libitum respectively for six weeks to induce metabolic syndrome.

Application of dry ground leaves of Moringa oleifera (Lam.) as soil nutrient augment for the productive assessment of seven accessions of bambara groundnut (Vigna subterranea (L.) Verdc.) was studied. The experimental pots (containing 4 kg of soil) were treated with 0 g (control), 10 g, 20 g and 35 g of dry powdered leaves in three replicates, arranged as completely randomised block design. Data collected include percent germination, number of days to flower bud formation, number of flower buds and flowers formed, number of pods produced per plant and 100-pod fresh and dry weights.

ABSTRACT: Studies have shown that edible clay contains metal contaminants, and its ingestion may be toxic to the body. The aim of this study was to investigate the effect of edible clay on serum lipid profile of female Wistar rats. Forty (40) healthy female Wistar rats, weighing 150 - 200 g, were sorted into four groups named group 1 - 4 with 10 rats each (n = 10). Group 1 was the control and orally received distilled water daily, while groups 2–4 received various doses of edible clay suspension ranging from 200, 800 and 1600 mg/kg respectively, through the same route for 28 days.

Tomato (Solanum lycopersicum) is a highly perishable fruit, susceptible to microbial spoilage and enzymatic degradation leading to significant post-harvest losses. Rise in the global demand for safe and healthy food with minimal synthetic preservatives has raised the need for natural preservatives. The preservative potential of Basil (Ocimum basilicum) essential oil (BEO) essential oil loaded chitosan- alginate coating on fresh tomato fruits was investigated.

Termites are very useful in tropical ecosystems as they contribute greatly to decomposition of organic matter, nutrients recycling, and to soil improvements and fertility. However, they also constitute very significant negative impacts to man and society worldwide, owing to their devastations on crops, forestry and to household and public resources.

Indoor fine dusts in residential buildings, public buildings and vehicles from Port Harcourt, Nigeria were assessed for their polycyclic aromatic hydrocarbons (PAHs) concentrations, compositional patterns, and human exposure risks. The PAHs in the dust samples were quantified by gas chromatograph equipped with mass spectrometry (GC-MS) after extraction by ultra-sonication with hexane/dichloromethane/acetone and cleaned up on a silica gel/alumina column.

This study assessed the spatial and seasonal variations, potential risks and sources of organochlorine pesticides in municipal solid waste dumpsites (MSWDs) in Delta State. Soil samples were obtained from twenty-seven MSWDs in Delta State. Soil samples were extracted with hexane/dichloromethane and cleaned up in a column of silica gel and florisil. The OCPs in the extracts were quantified with a gas chromatograph-mass spectrometry (GC-MS). The ∑20 OCPs levels in the soils varied between 0.74 and 7.29 ng g-1for the dry season and from 0.09 to 9.47 ng g-1 for the wet season.
