The toxicity of hair dressing salon effluent on Clarias gariepinus juveniles was studied using static bioassay method. This study investigated haematological, histopathological and biochemical changes in Clarias gariepinus juveniles. The fish samples were distributed randomly into T1 (800 ml/L), T2 (600 ml/L), T3 (400 ml/L), T4 (200 ml/L), and T5 control (water alone). All samples were studied in three replicates, in a completely randomized experiment. Mortality increased with  increased effluent concentrations; 250.96 ml/L was recorded as LC50 for 96 h.

The aim of this study was to ascertain the effects of peanut diet supplementation on glucose metabolism in rats exposed to 1, 2-dimethylhydrazine. Lactate dehydrogenase and glucose -6-phosphate dehydrogenase activities were used as indices for glucose metabolism. Eighty-four rats of both sexes were used for this study and were divided into seven groups of 6 rats each. 1, 2- dimethylhydrazine (DMH) was administered subcutaneously at a dose of 25 mg/kg body weight.Group A rats were maintained on rat feed, group B rats were maintained on rat feed and administered DMH once weekly for 12 weeks.

This study was conducted to determine the noise exposure level and the association between self-reported health effects and risk factors among workers in auto mechanic workshops in Abeokuta town, Nigeria. Noise levels were measured at selected auto mechanic sites. A cross-sectional study was also conducted among fifty workers using a wellstructured questionnaire across the sampling sites. The recorded noise level in the morning and afternoon ranged between 61.3 - 75.8 dB and 70.4 and 86.4dB respectively.

Hydro-priming is an important seed treatment technique for rapid seed germination. Cola species exhibits long and uneven germination. Hence this study was aimed at investigating the effect of hydro-priming durations on the germination and seedling growth of Cola parchycarpa and Cola rostrata. Five treatments (hydro-priming durations of 0 hour, 24 hours, 48 hours, 72 hours and 96 hours) were used and the experiment was laid out in a completely randomized design (CRD) with 6 replicates each. In C.

Cola rostrata and Cola parchycarpa are under-utilized indigenous kola plants, known as achicha by the Igbo natives in Nigeria, whose fruit pulps are edible and tasty. The proximate, vitamins, minerals and phytochemicals constituent of the fruit epicarp, fruit pulp and seed of C. rostrata and C. parchycarpa were evaluated using standard analytical laboratory procedures. The results revealed that C. rostrata and C. parchycarpa fruit pulps contained high moisture contents (56.56 % and 58.83 %) and carbohydrates (31.30 % and 55.39 %) respectively.

 The use of combination of artificial sweeteners, most importantly aspartame (E951) and acesulfame potassium (E950) in foods, beverages and other products is on the increase despite reports on their side effects. This study investigated the effects of combination of tolerable daily dose of both aspartame and acesulfame-k on blood glucose, lipids and cytokines of female Wistar rats. Twenty-five female Wister rats weighing 90.7±8.1 g were randomly assigned into five groups.

Global focus is currently on water, sanitation and hygiene (WaSH) due its public health and environmental significance. The aim of this study was to investigate the Water, Sanitation and Hygiene status of Uwelu and Evbareke spare parts markets in Benin City. Questionnaires were administered to evaluate the WaSH status of the markets. Physicochemical and bacteriological qualities of borehole water samples at the spare parts markets were investigated adopting standard analytical procedures and pour plate techniques respectively.

The study aimed to explore the lifestyle behaviours of women with varied parity and chronic disease statuses in Nigeria. This was a representative of women population in Ogun State in the southwest of Nigeria recruited between March and June 2022 using stratified sampling among the twenty (20) local governments in the three senatorial districts of the state.  Data on parity, chronic diseases, health status, dietary patterns, and anthropometric and lifestyle factors were collected using validated questionnaires.

Waste human hair causes environmental problems such as flooding, as a result of clogged drainages. It slowly breaks down over time to yield macro and trace minerals that are eventually returned to nature. Pleurotus ostreatus is cultivated worldwide, and it’s known to grow on several carbon and nitrogen sources. This study assessed the growth of P. ostreatus using potato dextrose agar (PDA) supplemented with Waste Human Hair Broth (WHHB). The growth of P.

Toxic exposures to cobalt chloride could occur from dietary, occupational, and medical sources. This study evaluated the ameliorative effect of oral administration of rutin and vitamin E on cobalt chloride (CoCl2)-induced oxidative stress in the brain of rats following exposure to cobalt chloride (CoCl2) toxicity. Wistar rats were randomly divided into five groups. Group 1 received only water, while group 2 received cobalt chloride (300 ppm) in drinking water.
