Air pollution assessment was carried out using chlorophyll concentration reduction criterion of some higher plants leaves such as (Masquerade tree) Polyathia longifolia (Sonn.) Thwaites, (Mango) Mangifera indica Linn. (Guava) Psidium guajava Linn. and (Indian Almond) Terminalia catappa Linn. as the bio-indicator species. The study was carried out at three (3) different locations namely polluted area (Ring Road, Benin City), slightly polluted area (Ekosodin Gate) and unpolluted area (Professor’s Staff Quarters) inside University of Benin, Ugbowo Campus, Benin City, Edo State, Nigeria.

Diets composition and dynamics of Eugerres plumieri, Gobioides broussonnetii, Elops aurus, Oreochromis niloticus and Heterotis niloticus in Ogun Coastal water were examined. The fish species were obtained from local fishermen fortnightly between August and October, 2021. The fishes were immediately placed on iced chess after collection and identification before transporting to the laboratory for further examination.

 Male reproductive processes are impacted by edible fats. The present work studied the effect of the consumption of a sunflower-enriched diet on sperm variables and reproductive hormones in male rats. A total of twenty male Wistar rats were used in this study. The Control group received the regular rat chow while the Treated group received the regular rat chow supplemented with 25% linoleic sunflower oil. After 28 days sperm variables, and reproductive hormones were assessed.

A study of the effect laundry wastewater on the microalga Chlorella vulgaris was carried out. The study was carried out using different treatments 0% (control), 5%, 10%, 20%, 30%, 40%, 50% of laundry wastewater. The microalgal growth responses were determined optically using absorbance on spectrophotometer at 750nm.

Environmental carcinogens or exogenous carcinogens includes chemical, biological, and physical agents that have  the potential to increase cancer risk because of prolonged high prevalence of exposure. Exposure can be through the respiratory, digestive, cutaneous or other possible contamination routes.

The effect of carcinogen exposure has been established to alter biochemical and hematological profiles in humans.

 Oxidative stress is a phenomenon caused by an imbalance between production and accumulation of oxygen reactive species (ROS) in the cells and tissues and the ability of a biological system to detoxify these reactive products. This study investigated the acute effect of different doses of ethanolic extract annabis sativa (EECS) on oxidative stress biomarkers in male (M) and female (F) Wister rats.

The chemical composition and in vitro properties of hexane and methanol extract of Sesamum indicum seeds (SIS) obtained from Kogi State, Nigeria were evaluated.

Exportin-1, the ubiquitous nuclear protein transporter, is widely confirmed as an active chemotherapeutic target in non-small cell lung cancer conditions, while Juglans mandshurica is a well-studied anticancer plant in some lung cancer cell lines.

Globally, millions of people in the developing world rely on medicinal plants to improve their primary health care, income generation and livelihood. An ethnomedicinal survey was conducted in four markets in Akure South Local Government Area of Ondo State, Nigeria. The aim was to document the diversity of medicinal herbs sold in the markets, their modes of preparation, the plant part(s) used, dosage, and the method of utilization. The respondents were primarily women, consisting of buyers and sellers of the herbals.
