Evaluation of seminal oxidation–reduction potential in male infertility
(Blackwell Publishing Ltd, 2021)The role of oxidative stress in male infertility has been broadly recognised, and the search for a new marker to determine the redox environment in semen has gained considerable interest. Oxidation–reduction potential (ORP) ... -
Evaluation of synergistic anticandidal activity of galenia africana extract and fluconazole against candida albicans and candida glabrata
(Elsevier, 2022-03)Candida infections have increased in recent years and are causing a serious public health concern. In addition, Candida species are becoming resistant to numerous antifungal drugs. It is for this reason that alternative ... -
Examination of maternal gingival crevicular fluid for the presence of selected periodontopathogens implicated in the pre-term delivery of low birthweight infants
(Landes Bioscience, 2010)Background: Reports show that more than 20 million infants world-wide are born prematurely with 95% of all pre-term births occurring in developing countries. Oral colonization of Gram-negative anaerobes has been implicated ... -
The excessive use of antioxidant therapy: A possible cause of male infertility?
(Wiley, 2018)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 ... -
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 ... -
An exploratory study of contractile force production in muscle fibers from patients with inflammatory myopathies
(Wiley-Blackwell, 2020)Introduction: The mechanism by which weakness develops in idiopathic inflammatory myopathies (IIMs) is still unclear. In this study we investigated the maximum force of single muscle fibers from patients with IIMs. Methods: ... -
Expression, purification and preliminary crystallographic analysis of recombinant human DEAD-box polypeptide 5
(International Union of Crystallography, 2010)The DEAD-box RNA helicase DDX5 is involved in many aspects of RNA processing and has been implicated in a number of cellular processes involving alteration of RNA secondary structure. The N-terminal region of DDX5, ... -
Face-to-face versus online-based lectures: A covid-19 induced study on assessments
(Frontiers Media, 2022)There is much debate regarding the impact of COVID-induced lockdown on the standard of assessments, mainly since students were assessed at home via an online assessment platform. Regular orthodox lectures and assessments ... -
Face-to-face versus online-based lectures: A COVID-19 induced study on assessments
(Frontiers in Education, 2022)The students were found to be resilient in adapting to things and learning, online presentations, and computer-based assessments. No gender-based difference or advantage to adjusting to newly introduced blended learning ... -
Fiber type and metabolic characteristics of skeletal muscle in 16 breeds of domestic dogs
(Wiley, 2023)The domestic dog (Canis lupus familiaris) species comprises hundreds of breeds, each differing in physical characteristics, behavior, strength, and running capability. Very little is known about the skeletal muscle ... -
The flexible, extended coil of the pdz-binding motif of the three deadly human coronavirus e proteins plays a role in pathogenicity
(MDPI, 2022)The less virulent human (h) coronaviruses (CoVs) 229E, NL63, OC43, and HKU1 cause mild, self-limiting respiratory tract infections, while the more virulent SARS-CoV-1, MERS-CoV, and SARS-CoV-2 have caused severe outbreaks. ... -
Functional landscape of SARS-CoV-2 cellular restriction
(Cell Press, 2021)A deficient interferon (IFN) response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been implicated as a determinant of severe coronavirus disease 2019 (COVID-19). To identify the molecular ... -
Further evidence for periodontal disease as a risk indicator for adverse pregnancy outcomes
(Elsevier, 2017)Although there is increasing evidence to suggest an association between periodontal disease and adverse pregnancy outcomes, the issue remains controversial. Study objective: This study tested the hypothesis that ... -
Genetic lesions within the 3a gene of SARS-CoV
(BioMed Central, 2005)A series of frameshift mutations within the 3a gene has been observed in culture-derived severe acute respiratory syndrome coronavirus (SARS-CoV). We report here that viral RNA from clinical samples obtained from SARS-CoV ... -
The genetic organisation of a 2,966 basepair DNA fragment of a Single Capsid Nucleopolyhedrovirus isolated from Trichoplusia ni
(Springer Verlag, 2002)In order to investiagte the genomic organization of the Trichoplusia ni Single Capsid Nucleoplyhedrovirus (TnSNPV) , a 2,966 base pairs (bp) genomic fragment was sequenced. The fragment was found to contain five open reading ... -
A Global Survey of Reproductive Specialists to Determine the Clinical Utility of Oxidative Stress Testing and Antioxidant Use in Male Infertility
(The world journal of men's health, 2021)Globally, infertility impacts 15% of couples trying to conceive. The incidence of male infertility has been increasing over the past several decades, ranging from 20% to 70% worldwide [1,2]. The male partner is found to ... -
Green nanotechnology as an innovative drug delivery approach for typha capensis and naringenin—new class of phytochemical embedded biocompatible gold nanoparticles in prostate cancer therap
