Reactive oxygen species and oxidative stress are closely associated with various pathologies such as neurodegenerative diseases, ageing and male infertility. Hence, antioxidants such as vitamin C, vitamin E, N‐acetyl ...
Group B streptococcus serotypes in pregnant women from the Western Cape region of South Africa
(Frontiers, 2018-12-04)
Background: Maternal colonization of Group B streptococci (GBS) during pregnancy is an important risk factor for neonatal morbidity and mortality. The aim of this study was to determine the prevalence and serotype distribution ...
The effects of carbon dots on immune system biomarkers, using the Murine Macrophage cell line RAW 264.7 and human whole blood cell cultures
(MDPI, 2018)
Abstract: Carbon dots (CDs) are engineered nanoparticles that are used in a number of bioapplications
such as bioimaging, drug delivery and theranostics. The effects of CDs on the immune system have
not been evaluated. ...
Rutin as a potent antioxidant: implications for neurodegenerative disorders
(Hindawi Publishing Corporation, 2018)
A wide range of neurodegenerative diseases (NDs), including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and
prion diseases, share common mechanisms such as neuronal loss, apoptosis, mitochondrial ...
Vaginal microbiomes associated with aerobic vaginitis and bacterial vaginosis
(Frontiers Media, 2018)
A healthy vaginal microbiota is considered to be significant for maintaining vaginal health
and preventing infections. However, certain vaginal bacterial commensal species serve
an important first line of defense of the ...

Quantitative assessment of heavy metal effects on sperm function using computer‐aided sperm analysis and cytotoxicity assays
(Wiley, 2018)
One known environmental risk factor impacting on human reproduction is heavy metal pollution. Although some metals (e.g., Cu, Se and Zn) have protective effects on the male reproductive system in low doses, heavy metals ...
Measuring Streptococcus mutans, Streptococcus sanguinis and Candida albicans biofilm formation using a real-time impedance-based system
(Elsevier, 2019-12-20)
Candida albicans and streptococci are amongst the most common fungal and bacterial organisms present in the
oral cavity, with a growing body of evidence implicating C. albicans in increased caries severity and in ...
CASA in invertebrates
(CSIRO Publishing, 2018)
Sperm movement has been described in several phyla of invertebrates. Yet, sperm motility has only been
quantified using computer-aided sperm analysis (CASA-Mot) in externally fertilising species (broadcast spawners) of ...
