Mitigation of Trypanosoma congolense-Associated Anemia and Expression of Trans-sialidase (TconTS) Gene Variants by Eugenol.

Purpose: African Animal Trypanosomosis (AAT) caused by Trypanosoma congolense is a parasitic disease affecting the livestock industry in sub-Saharan Africa and usually results in severe anemia, organ damage, and ultimately the death of the infected host. The present study was designed to investigate the possible chemotherapeutic effect of eugenol on T. congolense infections and its inhibitory effect on the trans-sialidase (TconTS) gene expression.

Exploring microbial worlds: a review of whole genome sequencing and its application in characterizing the microbial communities.

The classical microbiology techniques have inherent limitations in unraveling the complexity of microbial communities, necessitating the pivotal role of sequencing in studying the diversity of microbial communities. Whole genome sequencing (WGS) enables researchers to uncover the metabolic capabilities of the microbial community, providing valuable insights into the microbiome. Herein, we present an overview of the rapid advancements achieved thus far in the use of WGS in microbiome research.

Therapeutic efficacy of β-sitosterol treatment on infection, anemia development, and trans-sialidase () gene expression.

Background: African animal trypanosomiasis hinders sustainable livestock productivity in sub-Saharan Africa. About 17 million infected cattle are treated with trypanocides annually but most of the drugs are associated with drawbacks, necessitating the search for a promising chemotherapeutic agent.

Objectives: In this study, the effects of β-sitosterol on infection were investigated along with its effect on the trans-sialidase gene expressions.

A bibliometric analysis of the global impact of metaproteomics research.

Background: Metaproteomics is a subfield in meta-omics that is used to characterize the proteome of a microbial community. Despite its importance and the plethora of publications in different research area, scientists struggle to fully comprehend its functional impact on the study of microbiomes. In this study, bibliometric analyses are used to evaluate the current state of metaproteomic research globally as well as evaluate the specific contribution of Africa to this burgeoning research area.

Comparative G-Protein-Coupled Estrogen Receptor (GPER) Systems in Diabetic and Cancer Conditions: A Review.

For many patients, diabetes Mellitus and Malignancy are frequently encountered comorbidities. Diabetes affects approximately 10.5% of the global population, while malignancy accounts for 29.

β-Sitosterol could serve as a dual inhibitor of Trypanosoma congolense sialidase and phospholipase A: in vitro kinetic analyses and molecular dynamic simulations.

The involvement of Trypanosoma congolense sialidase alongside phospholipase A has been widely accepted as the major contributing factor to anemia during African animal trypanosomiasis. The enzymes aid the parasite in scavenging sialic acid and fatty acids necessary for survival in the infected host, but there are no specific drug candidates against the two enzymes. This study investigated the inhibitory effects of β-sitosterol on the partially purified T.

The Nigerian Military Public Health Response to COVID-19: A 14-Month Appraisal.

The COVID-19 pandemic has caused significant morbidity and mortality since its emergence in December 2019. In Nigeria, the government inaugurated the Presidential Task Force on COVID-19 to coordinate resources while the Nigeria Centre for Disease Control led the public health response. The Nigeria Ministry of Defence Health Implementation Programme (MODHIP), in partnership with the US Army Medical Research Directorate - Africa/Nigeria, responded immediately to the pandemic by establishing a public health emergency operations center to coordinate the military response in support of national efforts.

Potential epigenetic modifications implicated in triple- to quadruple-negative breast cancer transition: a review.

Current research on triple-negative breast cancer (TNBC) has resulted in delineation into the quadruple-negative breast cancer (QNBC) subgroup. Epigenetic modifications such as DNA methylation, histone posttranslational modifications and associated changes in chromatin architecture have been implicated in breast cancer pathogenesis. Herein, the authors highlight genes with observed epigenetic modifications that are associated with more aggressive TNBC/QNBC pathogenesis and possible interventions.

Chemotherapeutic potentials of β-ionone against Trypanosoma congolense infection: Inhibition of parasite proliferation, anemia development, trans-sialidase (TconTS3 and TconTS4) gene expressions, and phospholipase A.

Trypanosoma congolense is a pathogenic African animal trypanosome species causing devastating conditions leading to death of an infected host. The drawbacks of the existing trypanocidal drugs have led to the search for new drug candidates. In this study, β-ionone at 15 and 30 mg/kg body weight (BW) was orally administered to T.

Phloroglucinol as a Potential Candidate against Infection: Insights from In Vivo, In Vitro, Molecular Docking and Molecular Dynamic Simulation Analyses.

Sub-Saharan Africa is profoundly challenged with African Animal Trypanosomiasis and the available trypanocides are faced with drawbacks, necessitating the search for novel agents. Herein, the chemotherapeutic potential of phloroglucinol on infection and its inhibitory effects on the partially purified sialidase and phospholipase A (PLA) were investigated. Treatment with phloroglucinol for 14 days significantly ( < 0.

Interaction of spike protein with angiotensin converting enzyme inhibitors and selected compounds from the chemical entities of biological interest.

Background: Recent COVID-19 outbreak has prompted the search of novel therapeutic agents to treat the disease. The initial step of the infection involves the binding of the virus through the viral spike protein with the host angiotensin converting enzyme 2 (ACE2). In this study, the interaction of some ACE or ACE2 inhibitors and their analogues as well as selected compounds with the viral spike protein as a strategy to hinder viral-ACE2 interaction were investigated.

Estimation of the case fatality rate of COVID-19 epidemiological data in Nigeria using statistical regression analysis.

Following the emergence of COVID-19 outbreak, numbers of studies have been conducted to curtail the global spread of the virus by identifying epidemiological changes of the disease through developing statistical models, estimation of the basic reproduction number, displaying the daily reports of confirmed and deaths cases, which are closely related to the present study. Reliable and comprehensive estimation method of the epidemiological data is required to understand the actual situation of fatalities caused by the epidemic. Case fatality rate (CFR) is one of the cardinal epidemiological parameters that adequately explains epidemiology of the outbreak of a disease.

An Evaluation of Selected Populations for HIV-1 Vaccine Cohort Development in Nigeria.

Development of a globally effective HIV-1 vaccine will need to encompass Nigeria, one of the hardest hit areas, with an estimated 3.2 million people living with HIV. This cross-sectional Institutional Review Board (IRB) approved study was conducted in 2009-12 at four market sites and two highway settlements sites in Nigeria to identify and characterize populations at high risk for HIV; engage support of local stakeholders; and assess the level of interest in future vaccine studies.

Evaluation of Performance of Two Rapid Tests for Detection of HIV-1 and -2 in High- and Low-Prevalence Populations in Nigeria.

The availability of reliable human immunodeficiency virus types 1 and 2 (HIV-1/2) rapid tests in resource-limited settings represents an important advancement in the accurate diagnosis of HIV infection and presents opportunities for implementation of effective prevention and treatment interventions among vulnerable populations. A study of the potential target populations for future HIV vaccine studies examined the prevalence of HIV infections at six selected sites in Nigeria and evaluated the use of two rapid diagnostic tests (RDTs) for HIV. The populations included market workers at sites adjacent to military installations and workers at highway settlements (truck stops) who may have a heightened risk of HIV exposure.
