Sleep deprivation and neurological disorders
(Hindawi, 2020)Sleep plays an important role in maintaining neuronal circuitry, signalling and helps maintain overall health and wellbeing. Sleep deprivation (SD) disturbs the circadian physiology and exerts a negative impact on brain ... -
Smoking‐induced genetic and epigenetic alterations in infertile men
(Wiley, 2018)Male fertility rates have shown a progressive decrease in both developing and industrialised countries in the past 50 years. Clinical and epidemiological studies have demonstrated controversial results about the harmful ... -
Sperm morphology assessment in the era of intracytoplasmic sperm injection: Reliable results require focus on standardization, quality control, and training
(Korean Society for Sexual Medicine and Andrology, 2021)Semen analysis is the first, and frequently, the only step in the evaluation of male fertility. Although the laboratory procedures are conducted according to the World Health Organization (WHO) guidelines, semen analysis ... -
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 ... -
Strengths and limitations of different Chromogenic Media for the identification of Candida species
(Scientific & Academic Publishing, 2012)The treatment of invasive candidiasis and other Candida infections with the appropriate antifungal agent is assisted by the identification of Candida isolates to the species level. Rapid and accurate methods of differentiation ... -
The synergistic and neuroprotective effects of alcohol–antioxidant treatment on blood–brain barrier endothelial cells
(Wiley-Blackwell, 2020)Background: Alcohol (EtOH) is reported to adversely affect one of the most crucial roles of the blood–brain barrier (BBB), the regulation of its permeability, thereby compromising the stability of the homeostatic environment ... -
The threat of aerobic vaginitis to pregnancy and neonatal morbidity
(Women's Health and Action Research Centre, 2017)Aerobic vaginitis (AV) is an endogenous opportunistic infection brought about by the disruption of the normal vaginal microbiota. Its early diagnosis and treatment during pregnancy may reduce the risk of negative pregnancy ... -
Total antioxidant capacity—Relevance, methods and clinical implications
(Blackwell Publishing Ltd, 2021)Oxidative stress is pre-empted by an adequate level of antioxidants, which scavenge oxidants when they are produced in excess by different sources, including leukocytes and immature spermatozoa. Enzymatic antioxidants, ... -

Trends in semen parameters of infertile men in South Africa and Nigeria
(2023)There are conflicting reports on trends of semen parameters from different parts of the globe. However, in recent times there is dearth of information on the trend in Sub-Saharan countries. Therefore, in this study we ... -
Tunel assay: establishing a sperm dna fragmentation cut-off value for Egyptian infertile men
(Wiley Online Library, 2019)Male factor infertility is responsible for half of all infertility cases. Conventional semen analysis is inadequate to evaluate male fertility. Sperm DNA fragmentation (SDF) test can be done by: direct methods such as ... -
TUNEL assay—Standardized method for testing sperm DNA fragmentation
(Blackwell Publishing Ltd, 2021)Sperm DNA integrity is important for normal functions such as fertilization, implantation, pregnancy and fetal development. Sperm DNA fragmentation (SDF) is more common in infertile men and may be responsible for poor ... -
Tyrosinase and melanogenesis inhibition by indigenous African plants: A review
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)The indiscriminate use of non-regulated skin lighteners among African populations has raised health concerns due to the negative effects associated with skin lightener toxicity. For this reason, there is a growing interest ... -
Understanding human coronavirus HCoV-NL63
(Bentham Science, 2010)Even though coronavirus infection of humans is not normally associated with severe diseases, the identification of the coronavirus responsible for the outbreak of severe acute respiratory syndrome showed that highly ... -
Unlocking community capabilities across health systems in low- and middle-income countries: lessons learned from research and reflective practice
(BioMed Central, 2016)The right and responsibility of communities to participate in health service delivery was enshrined in the 1978 Alma Ata declaration and continues to feature centrally in health systems debates today. Communities are a ... -
Unveiling the Inhibitory Potentials of Peptidomimetic Azanitriles and Pyridyl Esters towards SARS-CoV-2Main Protease: A MolecularModelling Investigation
(MDPI, 2023)The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is responsible for COVID-19, which was declared a global pandemic in March 2020 by the World Health Organization (WHO). Since SARS-CoV-2 main protease plays ... -
An update on the techniques used to measure oxidative stress in seminal plasma
(Blackwell Publishing Ltd, 2021)Reactive oxygen species (ROS) are produced in significant amounts by spermatozoa and leucocytes. They are necessary to carry out various physiological functions such as sperm capacitation, hyperactivation, acrosome reaction, ... -
Use of a rat ex-vivo testis culture method to assess toxicity of select known male reproductive toxicants
(Elsevier, 2016)Due to the complex physiology of the testes, in vitro models have been largely unsuccessful at modeling testicular toxicity in vivo. We conducted a pilot study to evaluate the utility of the Durand ex vivo rat seminiferous ... -
