In vitro Antidiabetic and Antioxidant effects of different extracts of Catharanthus roseus and its indole alkaloid, vindoline
(MPDI, 2020)The Catharanthus roseus plant has been used traditionally to treat diabetes mellitus. Scientific evidence supporting the antidiabetic effects of this plant’s active ingredient-vindoline has not been fully evaluated. In ... -
Alpha-glucosidase and alpha-amylase inhibitory activities, molecular docking, and antioxidant capacities of salvia aurita constituents
(MPDI, 2020)Diabetes mellitus (DM) is one of the most dangerous metabolic diseases with a high rate of mortality worldwide. It is well known that insulin resistance and deficiency in insulin production from pancreatic β-cells are the ... -
Investigation of bioactive compounds in Crassocephalum rubens leaf and in vitro anticancer activity of its biosynthesized gold nanoparticles
(Elsevier, 2020)The development of cancer therapies has become difficult due to high metastasis, and lack of tissue selectivity, which in most cases affects normal cells. Demand for anticancer therapy is therefore increasing on daily ... -
Identification of biomarkers for the accurate and sensitive diagnosis of three bacterial pneumonia pathogens using in silico approaches
(Springer Nature, 2020): Pneumonia ranks as one of the main infectious sources of mortality among kids under 5 years of age, killing 2500 a day; late research has additionally demonstrated that mortality is higher in the elderly. A few ... -
Glucose-uptake activity and cytotoxicity of diterpenes and triterpenes isolated from lamiaceae plant species
(2020)The prevalence of diabetes mellitus (DM), considered one of the most common metabolic disorders, has dramatically increased and resulted in higher rates of morbidity and mortality around the world in the past decade. It ... -
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 ... -
Source rock evaluation of Afowo clay type from the Eastern Dahomey Basin, Nigeria: Insights from different measurements
(Springer Nature, 2020)The Cretaceous Afowo Formation in the Eastern Dohamey Basin is characterized by an admixture of lithofacies ranging from sandstones, claystones, shales, clays, sand/shale, and sand/clay intercalations. The sandy facies, a ... -
Differentially expressed serum proteins from obese Wistar rats as a risk factor for obesity-induced diseases
(Springer Nature, 2020)Obesity is a chronic disease that negatively affects life expectancy through its association with life-threatening diseases such as cancer and cardiovascular diseases. Expression proteomics combined with in silico interaction ... -
Symptom evolution following the emergence of maize streak virus
(eLife Sciences Publications, 2020)For pathogens infecting single host species evolutionary trade-offs have previously been demonstrated between pathogen-induced mortality rates and transmission rates. It remains unclear, however, how such trade-offs ... -
Complex sequential data analysis: A systematic literature review of existing algorithms
(SAICSIT, 2020)This paper provides a review of past approaches to the use of deep-learning frameworks for the analysis of discrete irregularpatterned complex sequential datasets. A typical example of such a dataset is financial data ... -
Diagnostic approaches of pneumonia for commercial-scale biomedical applications: An overview
(Taylor & Francis, 2020)Pneumonia remains the leading infectious cause of death among children under five years of age, and the elderly. Several biomarkers, which have been identified for its diagnosis lack specificity, as they could not ... -
Cellular and molecular targets of waterbuck repellent blend odors in antennae of glossina fuscipes fuscipes newstead, 1910
(Frontiers Media S.A., 2020)Insects that transmit many of the world’s deadliest animal diseases, for instance trypanosomosis, find their suitable hosts and avoid non-preferred hosts mostly through olfactory cues. The waterbuck repellent blend (WRB) ... -
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 ... -
Ethnopharmacology, therapeutic properties and nutritional potentials of Carpobrotus edulis: A comprehensive review
(MPDI, 2020)Carpobrotus edulis, formerly known as Mesembryanthemum edule L, belongs to the Aizoaceae family of plants. It is a facultative halophytic invasive medicinal and edible succulent plant that is native to South Africa and ... -
Tyrosinase and melanogenesis inhibition by indigenous African plants: A review
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)The indiscriminate use of non-regulated skin lighteners among African populations has raised health concerns due to the negative effects associated with skin lightener toxicity. For this reason, there is a growing interest ... -
An analysis of the trends, characteristics, scope, and performance of the Zimbabwean pharmacovigilance reporting scheme
(Wiley-Blackwell, 2020)We aimed to determine the reporting trends and characteristics of Individual Case Safety Reports (ICSRs) from the Zimbabwean national pharmacovigilance system. ICSRs submitted to VigiBaseTM, the World Health Organisation's ... -
Neuroprotective activities of Boophone haemanthoides (amaryllidaceae) extract and its chemical constituents
