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 ... -
Male infertility
(Lancet Publishing Group, 2021)It is estimated that infertility affects 8–12% of couples globally, with a male factor being a primary or contributing cause in approximately 50% of couples. Causes of male subfertility vary highly, but can be related to ... -
Male infertility, oxidative stress and antioxidants
(IntechOpen, 2021)Within the male reproductive system, oxidative stress (OS) has been identified as prevailing etiology of male infertility. The effects of reactive oxygen species (ROS) on male fertility depend on the dimensions, “modus ... -
Maternal and Neonatal Group B Streptococcus colonisation in a cohort of Libyan women
(2021-01-18)Background: Group B streptococcus (GBS) may be vertically transmitted from mother to infant during labour and cause life threatening neonatal sepsis. The objective of this study was to determine the risk and prevalence ... -
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 ... -
Medicinal properties and in vitro biological activities of selected helichrysum species from South Africa: A review
(MDPI, 2021)The genus Helichrysum Mill comprises hundreds of species that are mostly flowering perennial shrubs. Some of these plants that belong to the Helichrysum species are used in traditional medicine to treat cough, back pain, ... -
MERS-CoV: Understanding the latest human coronavirus threat
(MDPI, 2018)Human coronaviruses cause both upper and lower respiratory tract infections in humans. In 2012, a sixth human coronavirus (hCoV) was isolated from a patient presenting with severe respiratory illness. The 60-year-old man ... -
Metronidazole in the Prophylaxis and treatment of Anaerobic Infection
(Health and Medical Publishing Group, 1978)The influence of prophylactic metronidazole on vaginal carriage rates of anaerobes and the development of postoperative anaerobic infection was studied in 104 women who underwent abdominal hysterectomy. Metronidazole ... -
The Microbial Aetiology of Periodontal Diseases
(InTech, 2012)Introduction: The study of the aetiology of periodontal diseases has continued for decades with much progress shown in the last two decades. Having moved through periods of “whole” plaque (with emphasis on mass) being ... -
Microplastic sources, formation, toxicity and remediation: A review
(Springer, 2023)Microplastic pollution is becoming a major issue for human health due to the recent discovery of microplastics in most ecosystems. Here, we review the sources, formation, occurrence, toxicity and remediation methods of ... -
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 ... -
Microtubular dysfunction and male infertility
(Korean Society for Sexual Medicine and Andrology, 2018)Microtubules are the prime component of the cytoskeleton along with microfilaments. Being vital for organelle transport and cellular divisions during spermatogenesis and sperm motility process, microtubules ascertain ... -
Molecular detection of tick-borne pathogen diversities in ticks from livestock and reptiles along the shores and adjacent islands of lake Victoria and lake Baringo, Kenya
(Frontiers Media, 2017)Tick-borne pathogens (TBPs) are responsible for some of the most serious emerging infectious diseases facing sub-Saharan Africa (SSA) and the rest of the world today (1, 2). In Kenya, TBPs (including viral diseases—arboviruses) ... -
