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 ...
High levels of oxidation–reduction potential in frozen-thawed human semen are significantly correlated with poor post-thaw sperm quality
(Wiley-Blackwell, 2020)
This study examined the relationship between oxidation–reduction potential (ORP) in frozen-thawed semen and the post-thaw sperm parameters. Levels of ORP were measured in 25 samples from men presenting for routine infertility ...
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 ...
Aqueous leaf extract of Sutherlandia frutescens attenuates ROS-induced apoptosis and loss of mitochondrial membrane potential in MPP+-treated SH-SY5Y cells
(University of Benin, 2020)
To investigate the neuroprotective activity of the aqueous extract of Sutherlandia frutescens (SF) against 1-methyl-4-phenylpyridinium (MPP+)-induced toxicity in SH-SY5Y neuroblastoma cells. Methods: SH-SY5Y neuroblastoma ...
Novel additive for sperm cryopreservation media: Holotheria parva coelomic cavity extract protects human spermatozoa against oxidative stress—A pilot study
(Wiley-Blackwell, 2020)
Cryopreservation is the most effective method for preserving semen for a long period of time. However, during the freeze–thaw process, production of reactive oxygen species (ROS) leads to a steep reduction in sperm fertility ...
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 ...
Development of molecular tools for honeybee virus research: the South African contribution
(Academic Journals, 2003)
Increasing knowledge of the association of honeybee viruses with other honeybee parasites, primarily
the ectoparasitic mite Varroa destructor, and their implication in the mass mortality of honeybee
colonies has resulted ...
Microstructurally-based constitutive modelling of the skin – Linking intrinsic ageing to microstructural parameters
(Elsevier, 2018)
A multiphasic constitutive model of the skin that implicitly accounts for the process of intrinsic (i.e. chronological) ageing via variation of the constitutive parameters is proposed. The structurally-motivated constitutive ...
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 ...
Life-long programming implications of exposure to tobacco smoking and nicotine before and soon after birth: Evidence for altered lung development
(MDPI, 2011)
Tobacco smoking during pregnancy remains common, especially in indigenous communities, and likely contributes to respiratory illness in exposed offspring. It is now well established that components of tobacco smoke, notably ...
