The effect of Nigella sativa oil and metformin on male seminal parameters and testosterone in Wistar rats exposed to an obesogenic diet
(Elsevier, 2021)Obesity is a significant global health and socio-economic challenge, and considered an important risk factor for poor health outcomes including male reproductive dysfunction and infertility. As excess adiposity causes ... -
Silver nanoparticles stimulates spermatogenesis impairments and hematological alterations in testis and epididymis of Male rats
(MDPI, 2020)The potential pharmaceutical application of nanoparticles has led to the toxicity within the male reproductive system. In the present study, the effects of silver nanoparticles (Ag-NPs) on hematological parameters, free ... -
An insight into the mechanism of holamine- and funtumine-induced cell death in cancer cells
(MDPI, 2020)Holamine and funtumine, steroidal alkaloids with strong and diverse pharmacological activities are commonly found in the Apocynaceae family of Holarrhena. The selective anti-proliferative and cell cycle arrest effects of ... -
The effect of Nigella sativa oil and metformin on male seminal parameters and testosterone in Wistar rats exposed to an obesogenic diet
(Elsevier, 2020)Obesity is a significant global health and socio-economic challenge, and considered an important risk factor for poor health outcomes including male reproductive dysfunction and infertility. As excess adiposity causes ... -
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 ... -
The beneficial role of anchomanes difformis in stz-induced reproductive dysfunction in male wistar rats
(Dove Medical Press, 2020)Progression of diabetes mellitus has increasingly led to several diabetic complications. Diabetes is one of the major factors implicated in male reproductive system damage. Recent approaches such as the use of medicinal ... -
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 ... -
Ritalinic acid stimulates human sperm motility and maintains vitality in vitro
(Korean Society for Sexual Medicine and Andrology, 2020)To evaluate the in vitro impact of ritalinic acid (RA), a major metabolite of methylphenidate (drug to treat attention-deficit hyperactivity disorder), on sperm motility, vitality and oxidative stress. Materials and Methods: ... -
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 ... -
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 ... -
Seminal oxidation–reduction potential levels are not influenced by the presence of leucocytospermia
(Wiley-Blackwell, 2020)Oxidative stress (OS) is characterised by an excessive amount of reactive oxygen species (ROS) which negatively affect sperm functions. In this study, the influence of leucocytes on seminal oxidation–reduction potential ... -
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: ... -
Scientific landscape of oxidative stress in male reproductive research: A scientometric study
(Elsevier, 2020)Unraveling the role of reactive oxygen species and associated oxidative stress (OS) in male reproduction is one of the key areas of male reproductive research. This article illustrates the scientific landscape of OS in ... -
Quest for the best—a move to anatomical endoscopic enucleation of the prostate
(Wiley-Blackwell, 2020)The history of surgical enucleation for the treatment of lower urinary tract symptoms caused by benign prostatic enlargement dates back more than 100 years (Freyer, 1919). Open prostatec-tomy (OP) is an invasive procedure ... -
PICSI vs. MACS for abnormal sperm DNA fragmentation ICSI cases: A prospective randomized trial
(Springer Nature, 2020)Purpose: To know which sperm selection technique, physiological intracytoplasmic sperm injection (PICSI) or magnetic-activated cell sorting (MACS), is better for the selection of sperm with abnormal sperm DNA fragmentation ... -
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 ... -
Is there a link between the pathogenic human Coronavirus envelope protein and immunopathology? A review of the literature
(Frontiers Media S.A., 2020)Since the severe acute respiratory syndrome (SARS) outbreak in 2003, human coronaviruses (hCoVs) have been identified as causative agents of severe acute respiratory tract infections. Two more hCoV outbreaks have since ... -
Alkaloids: Therapeutic Potential against Human Coronaviruses
(MPDI, 2020)Alkaloids are a class of natural products known to have wide pharmacological activity and have great potential for the development of new drugs to treat a wide array of pathologies. Some alkaloids have antiviral activity ... -
Green tea consumption increases sperm concentration and viability in male rats and is safe for reproductive, liver and kidney health
(Springer Nature, 2020)Green tea is a popularly consumed beverage worldwide and contains polyphenols, whose antioxidant activities could improve sperm parameters and fertility thereof. We investigated the effect of green tea on the male rat ... -
Are claudin-5 tight-junction proteins in the blood-brain barrier porous?
(Wolters Kluwer Health, 2020)The capillaries of the brain are particularly special, as they are not simply conduits for blood, but are primarily responsible to ensure that the neurons function in a strictly regulated homeostatic interstitium. Brain ...
