In vivo toxicological study of aqueous extracts of Vitex payos fruits
(2020-08)The plant Vitex payos is used in folk medicine to treat several ailments. Despite Vitex payos’, ethno medicinal benefits, very few studies have described the fruits’ potential toxicity. The aim of the present study was to ... -
Frequency of the TP53 Codon 47 and Codon 72 polymorphisms in HIV infected women with histologically confirmed cervical and vulvar pre cancer and invasive cancer reporting at an HIV clinic in Harare, Zimbabwe
(2020-08)Cervical cancer is the most common cancer in Zimbabwean women as well as the leading cause of female cancer deaths. There has been an increase in the cervical cancer incidence of Zimbabwe from 56.2 % reported in 2012 to ... -
A bioinformatics approach to define the Eps-D1 subtelomeric chromosomal deletion in bread wheat (Triticum aestivum).
(2020-08)Flowering time is one of the critical determinants of yields in flowering plants. The flowering time in bread wheat (Triticum aestivum) is directly determined by vernalization, photoperiod response and earliness per se ... -
Gas chromatography-mass spectrometry analysis in vitro antibacterial efficacy and in silico molecular docking of compounds produced by endophytes isplated from indegenous medical plants.
(2020-08)Native medicinal plants have been traditionally used to treat various bacterial infections, fungal infections, cancers, viral infections and cardiovascular diseases. Endophytic bacteria residing inside the tissues of ... -
Antimicrobial potential of herbal creams based on extracts from Combretum zeyheri
(2021-11)Microbial resistance has become a problem in the treatment of infectious diseases and the use of plant phytochemicals has been a valuable potential source of lead compounds that can be used for sustaining human health. ... -
Viral load comparison between SARS-CoV-2 symptomatic and asymptomatic patients during the course of COVID-19 infection
(2021-07)Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel respiratory virus is the etiological factor of COVID-19 disease which started in the Wuhan Province, China in December of 2019. Symptoms include a dry ... -
Determination of lymphocyte and cytokine profiles associated with Coronavirus disease 2019 severity
(2021-07)Coronavirus disease 2019 (COVID-19) is caused by a recently identified virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the disease is a pandemic. Recurrent waves of infection continue to overwhelm ... -
Use of bacteriophages to control salmonella in crocodiles and optimisation of a light induced expression system for endolysin.
(2021-08)The aims of this study were to isolate bacteriophages from crocodile feeding pen wastewater and to evaluate their effectiveness against clinical Salmonella species, Escherichia coli and Enterobacter cloacae. Also, the ... -
Isolation and identification of polystyrene-degrading bacteria from the gut of Tenebrio molitor based on the nucleotide sequence of the 16S rRNA gene
(2021-10)The excessive use of polystyrene as a packaging material has resulted in a rise in environmental pollution. Polystyrene waste has continually increased water pollution, soil pollution and the closing of landfill sites since ... -
