Although the exact ways of actions are not fully understood, the possible modes of probiotics action include the following: enhancement of epithelial barrier function; increased adhesion to intestinal epithelial cells; competitive exclusion of pathogenic microorganisms, and; production of antimicrobial peptides.
Vine Cutting Propagation in Four Varieties of Yam Using Different Planting Media
by Gbadamosi, A.E., Ajayi, A.T. and Osekita, O.S.
Yams (Dioscorea spp), are one of the most important staple crops in West Africa. They belong to the family Dioscoreaceae, which produce economically important tubers and bulbils. There are many cultivars of yam, though only six are important as staple foods in the tropics.
Genetic variation & tolerance indices interactions among wheat accessions under drought
by Victor Olugbenga Olumekun, Abiola Toyin Ajayi and Oluwasegun Victor Ibidapo
In recent times, wheat has gained more acceptance and utilisation over the traditional staples such as tubers and other cereals in Africa as a consequence of increased demand for dietary enhancement due to urbanisation and increased population in regions where staple was predominantly known to come from maize.
Crossability and inheritance of seed coat colour in cowpea at F1 generation
by Abiola Toyin Ajayi
Cowpea (Vigna unguiculata L. Walp) is a crop of significant importance in Africa; it serves as a source of proteins in the tropical and subtropical countries, where Nigeria is ranked the highest in terms of production. It is a source of income for the people of Africa where it is widely cultivated for different purposes. Despite the good attributes of cowpea, one of the major constraints hampering its productivity in Nigeria is drought.
An Introduction to Lipase
Lipases are a group of water-soluble enzymes that catalyze the hydrolysis (and synthesis) of ester bonds in insoluble acylglycerols at lipid-water interfaces. Lipases hydrolyze triacylglycerides into diacylglycerides, monoacylglycerides, free fatty acids and glycerols. Lipase reaction occurs at the interface between the aqueous and the oil phases because of an opposite polarity between the enzyme (hydrophilic) and their substrates (lipophilic).

Overview of Hypertension
Hypertension (HTN) is a persistently abnormal elevated blood pressure which in the long-term, results in end-organ damage and consequently, increases morbidity and mortality. Till date, the cause of hypertension is unknown, however, there are many possibilities and influences related to hypertension in patients.
Genetic Disease Focus: Ataxia–telangiectasia
Ataxia–telangiectasia (AT or A–T), also referred to as ataxia–telangiectasia syndrome or Louis–Bar syndrome is a rare, neurodegenerative, autosomal recessive disease causing severe disability. Ataxia refers to poor coordination and telangiectasia to small dilated blood vessels, both of which are hallmarks of the disease. A–T affects many parts of the body: It impairs certain areas of the brain including the cerebellum, causing difficulty with movement and coordination. It weakens the immune […]

Guidance on Community Social Distancing During COVID-19 Outbreak (1)
by Africa CDC
In Africa, the number of COVID-19 cases and impacted countries has been increasing steadily. As of 12 March 2020, 129 cases have been diagnosed in 12 countries, with one death recorded. The experience in countries outside Africa is that, after initial cases are diagnosed, community transmission occurs rapidly.
