Importance and relevance of phytochemicals present in Galenia Africana
(Hindawi, 2022)Many people in developing countries rely primarily on medicinal plants as their main source of healthcare, particularly for the treatment of skin infections. Despite the widespread use of medicinal plants, there is a lack ... -
Exosomes form tunneling nanotubes (TUNTs) in the blood-brain barrier: A nano-anatomical perspective of barrier genesis
(Frontiers Media, 2022)The blood-brain barrier (BBB) is a robust interface between the blood and the central nervous system. Barrier type endothelium is able to limit paracellular (PC) movement, relegating molecular flux to the transendothel ... -
The stability and anti-angiogenic properties of titanium dioxide nanoparticles (tio2nps) using caco-2 cells
(MDPI, 2022)Titanium dioxide nanoparticles (TiO2NPs) are found in a wide range of products such as sunscreen, paints, toothpaste and cosmetics due to their white pigment and high refractive index. These wide-ranging applications ... -
Green tea (Camellia sinensis) aqueous extract improved human spermatozoa functions in vitro
(ResearchGate, 2022)Background: Idiopathic causes of infertility is associated with oxidative stress. Antioxidants are known to scavenge the excessive production of reactive oxygen species (ROS). Green tea (Camellia sinensis) contains polyphenols ... -
