Amino acids 1055 to 1192 in the S2 Region of severe acute respiratory syndrome Coronavirus S Protein induce neutralizing antibodies: Implications for the development of vaccines and antiviral agents
(American Society for Microbiology, 2005)The spike (S) protein of the severe acute respiratory syndrome coronavirus (SARS-CoV) interacts with cellular receptors to mediate membrane fusion, allowing viral entry into host cells; hence it is recognized as the primary ... -
Anaerobes and bacterial vaginosis in pregnancy: virulence factors contributing to vaginal colonisation
(Multidisciplinary Digital Publishing Institute, 2014)The aetiology and pathogenesis of bacterial vaginosis (BV) is unclear but it appears to be associated with factors that disrupt the normal acidity of the vagina thus altering the equilibrium between the normal vaginal ... -
Antimicrobial-resistant Klebsiella species isolated from free-range chicken samples in an informal settlement
(Termedia Publishing House, 2012)Sub-therapeutic doses of antimicrobial agents are administered routinely to poultry to aid growth and to prevent disease, with prolonged exposure often resulting in bacterial resistance. Crossover of antibiotic resistant ... -
Antioxidant and apoptosis-inhibition potential of Carpobrotus edulis in a model of parkinson’s disease
(African Association of Physiological Sciences, 2018)Background: Parkinson’s disease (PD) is a neurological disorder resulting from the progressive loss of dopaminergic neurons. There is currently no known cure for PD, thus the search for complementary and alternative medicines ... -
Antioxidant, anti-diabetic, and anti-inflammation activity of Garcinia livingstonei aqueous leaf extract: a preliminary study
(Multidisciplinary Digital Publishing Institute (MDPI), 2024)Diabetes mellitus (DM) is the second leading cause of mortality globally. The increased concern for DM is due to the underlying complications accompanying hyperglycaemia, associated with oxidative stress and consequent ... -
Aqueous extractions of mondia whitei root improve human sperm function in vitro
(Elsevier B.V., 2024)Introduction: Mondia whitei (Mw) is a prominent African medicinal plant that is widely used as traditional treatment in the management of sexual dysfunction and male infertility. Yet, there is a paucity of scientific ... -
