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 ... -
Morphological and physiological responses of Calobota sericea plants subjected to water limitation and subsequent rewatering
(Taylor and Francis Group, 2021)Calobota sericea is a native legume of South Africa, confined to the water-limited rangelands, and it has recently been prioritised for additional characterisation regarding its pasture potential. In this study, we examined ... -
The effects of in utero exposure to teratogens on organ size: A prospective paediatric study
(Cambridge University Press, 2021)In low-income countries, prospective data on combined effects of in utero teratogen exposure are lacking and necessitates new research. The aim of the present study was to explore the effect of in utero teratogen exposure ... -
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 ... -

(MDPI, 2022)We would like to thank F. Pallotti and his colleagues for their positive comments [1] on our SWOT analysis of the strengths, weaknesses, threats and opportunities of the sixth edition of the WHO manual on semen analysis ... -
Biosynthesis of silver nanoparticles using Bersama engleriana fruits extracts and their potential inhibitory effect on resistant bacteria
(MDPI, 2022)The absence of novel, safe, and effective bactericide is an urgent concern worldwide and remains a challenge in scientific communities. The unique proprieties of silver nanoparticles (SNPs) synthesized from plant extracts ... -
The Ism between endothelial cilia and endothelial nanotubules is an evolving concept in the genesis of the BBB
(MDPI, 2022)The blood–brain barrier (BBB) is fundamental in maintaining central nervous system (CNS) homeostasis by regulating the chemical environment of the underlying brain parenchyma. Brain endothelial cells (BECs) constitute ... -
Oxidative stress and assisted reproduction: A comprehensive review of its pathophysiological role and strategies for optimizing embryo culture environment
(MDPI, 2022)Oxidative stress (OS) due to an imbalance between reactive oxygen species (ROS) and antioxidants has been established as an important factor that can negatively affect the outcomes of assisted reproductive techniques ... -
Morphometric and structural analysis of Florida manateespermatozoa
(Wiley, 2022)Sperm characteristics, such as sperm morphology and sperm morphometry areimportant in assessing sperm quality. This is especially important for the man-agement and conservation of endangered and exotic species, like the ... -
Cost of Traditional Herbal Medicines for Noncommunicable Diseases in Rural and Urban Communities in South Africa
(Elsevier Inc., 2022)Objectives: This study assessed traditional herbal medicine (THM) and conventional medicine (CM) utilization among par- participants with a noncommunicable diseases in South Africa. Methods: A cross-sectional study of the ... -
Real-time assessment of Candida biofilm disruption by Galenia africana
(2022-05-25)Candida species often cause opportunistic infections in immunocompromised patients and are able to form highly structured biofilms that protect the yeast cells from the external environment and the action of antimicrobials. ... -
Male age and progressive sperm motility are critical factors affecting embryological and clinical outcomes in oocyte donor ICSI cycles
(Reproductive Sciences, 2021)This retrospective cohort study aimed to explore whether paternal age and semen quality parameters affect the embryological and clinical outcomes of ICSI with oocyte donation. A total of 339 oocyte donation (OD)-ICSI cycles ... -
