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 ... -
In vitro evaluation of the anti-diabetic potential of aqueous acetone Helichrysum petiolare extract (AAHPE) with molecular docking relevance in diabetes mellitus
(MDPI, 2021-12)Diabetes mellitus (DM) is a chronic metabolic condition that can lead to significant complications and a high fatality rate worldwide. Efforts are ramping up to find and develop novel α-glucosidase and α-amylase inhibitors ... -
An in vitro study on the combination effect of metformin and n-acetyl cysteine against hyperglycaemia-induced cardiac damage
(MDPI - Publisher of Open Access Journals, 2019)Chronic hyperglycaemia is a major risk factor for diabetes-induced cardiovascular dysfunction. In a hyperglycaemic state, excess production of reactive oxygen species (ROS), coupled with decreased levels of glutathione, ... -
In-vitro cytotoxicity, anti-bacterial and anti-inflammatory activities of ecklonia radiataand jania verrucosafrom Eastern Cape, South Africa
(University of Benin, 2022)Seaweeds are marine floras constituting in part to over 90% of the oceanic biomass. Despite the enrichments of seaweeds, their potentials are largely unexplored. Hence, this study evaluated the phytochemical screening, ... -
Increasing extracellular cellulase activity of the recombinant Saccharomyces cerevisiae by engineering cell wall-related proteins for improved consolidated processing of carbon neutral lignocellulosic biomass
(Elsevier, 2022)Sustainable bioproduction using carbon neutral feedstocks, especially lignocellulosic biomass, has attracted increasing attention due to concern over climate change and carbon reduction. Consolidated bioprocessing (CBP) of ... -
Indigenous African cereal crops can contribute to mitigation of the impact of climate change on food security
(Arid land institute, 2021)Zea mays L. (maize) is one of the top three cultivated cereals globally, along with wheat and rice. The United States, China, and Brazil are among the largest producers of maize, producing approximately 79% of the world’s ... -
Inhibition of bacteria associated with wound infection by biocompatible green synthesized gold nanoparticles from South African plant extracts
(MDPI, 2017)Unlike conventional physical and chemical methods, the biogenic synthesis of gold nanoparticles (GNPs) is considered a green and non-toxic approach to produce biocompatible GNPs that can be utilized in various biomedical ... -
Inhibition of NOS- like activity in maize alters the expression of genes involved in H2O2 scavenging and glycine betaine biosynthesis
(Nature Publishing Group, 2018)Nitric oxide synthase-like activity contributes to the production of nitric oxide in plants, which controls plant responses to stress. This study investigates if changes in ascorbate peroxidase enzymatic activity and ... -
Inhibitory potential of repurposed drugs against the SARS-CoV-2 main protease: A computational-aided approach
(Taylor and Francis, 2020)The exponential increase in cases and mortality of coronavirus disease (COVID-19) has called for a need to develop drugs to treat this infection. Using in silico and molecular docking approaches, this study investigated ... -
