Comparison of cytokine and immunoglobulin levels in blood between asymptomatic serum sryptococcal antigen positive and negative HIV-positive individuals with CD4 counts <100 cells/ μl. A nested case-control study in Harare.
(University of Zimbabwe, 2021-06-09)
Background: Cryptococcosis is still a leading cause of mortality among patients with advanced HIV infection. Although CD4 T-cell deficiency is necessary for HIV-associated cryptococcosis, not all severely immunocompromised ...
Markers of inflammation, morbidity and mechanisms mediating resistance against Schistosoma haematobium infection in preschool age ahildren (Children aged five years and below).
(University of Zimbabwe, 2021-06-09)
Schistosomiasis is caused by a blood fluke worm of the genus Schistosoma. Adult worms can live for decades in the human host releasing ova causing inflammatory and obstructive disease in the urinary system. The preschool-age ...
Impact of climate change and biotic factors on avifauna diversity and spatial distribution in the mid-Zambezi Valley, Zimbabwe.
(University of Zimbabwe, 2021-06)
Construction of Lake Kariba on the Zambezi River restructured the biodiversity of the Zambezi Valley. However, studies on how the avian community of Kariba has changed since construction of the lake are scant. This study ...
The Taxonomy, ecology and trematode infections of gastropod snails on the northern shoreline of Lake Kariba, Zimbabwe.
(University of Zimbabwe, 2021-08)
Freshwater gastropods make up about 75% of all freshwater molluscs in the African continent. Their classification and identification have been largely based on morphological characteristics, with the main focus on shell ...
Upper Bounds on the Diameter of Bipartite and Triangle-Free Graphs with Prescribed Edge Connectivity
(HINDAWI, 2020-09-03)
Graph theory is used to study the mathematical structures of pairwise relations among objects. Mathematically, a pair G=(V,E) is a crisp graph, where V is a nonempty set and E is a relation on V[1]. -e order of a graph G ...
An Upper Bound on the Radius of a 3-Vertex-Connected C4-Free Graph
(HINDAWI, 2020-08-04)
Let G=(V,E) be a finite, connected, undirected graph with vertex set V and edge set E. -e distance dG (u,v) between two vertices u, v of G is the length of a shortest u-v path in G.-e eccentricity ec(v)of a vertex v∈V is ...
Promoter single nucleotide polymorphisms in pro-inflammatory cytokine genes in S. haematobium infected and the risk of prostate cancer development
(2021-10)
This thesis reports the findings of a thorough study to establish the role of the genetic variations in the pro-inflammatory genes and the risk of developing prostate cancer (PCa) in male individuals residing in a ...
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 ...
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 ...
