Ethnopharmacological Relevance: Zimbabwe is a key biodiversity domain in sub-Saharan Africa and ethnoveterinary medicines play an integral role in livestock health. However, knowledge on whether plants are used by only a small proportion of people or whether similar uses exist in different communities and in a more regional context is incompletely documented.
Aim Of The Study: Firstly, the study documented plant-based complementary medicines used for managing goat ailments.

Shifting to dietary patterns rich in plants and low in animal-source foods could substantially lower emissions from the food sector while reducing the global burden of non-communicable diseases. The EAT-Lancet Commission proposed the planetary health diet (PHD) to emphasise plant-forward diets and set global targets to guide an urgently needed food-system transformation. However, the PHD's meat-reduction approach has attracted criticism and prompted debate on the potential micronutrient shortfalls of the plant-forward dietary approach.

Dinosaurs dominated Mesozoic terrestrial ecosystems for ∼160 million years, but their biogeographic origin remains poorly understood. The earliest unequivocal dinosaur fossils appear in the Carnian (∼230 Ma) of southern South America and Africa, leading most authors to propose southwestern Gondwana as the likely center of origin. However, the high taxonomic and morphological diversity of these earliest assemblages suggests a more ancient evolutionary history that is currently unsampled.

To address microbial infections and combat drug resistance, we designed, synthesized, and evaluated three novel s-triazine clubbed pharmacophores: 1-acetylpyrazoline (5a-e), 2-aminopyrimidine (6a-e), and 1,5-benzodiazepine (7a-e). These were derived from chalcone (4a-e), showing improved pharmacological profiles. The compounds underwent characterization by FTIR, NMR, and Mass Spectroscopy, and their antimicrobial activities, along with structure-activity relationships (SAR), were assessed using in silico and in vitro methods.

Background: Neuroblastoma (NB) is the most common extracranial malignant solid tumor in children, accounting for >15 % of cancer-related deaths in children. We analyzed the epidemiological statistical indicators of neuroblastoma and other peripheral nervous system tumors patients from 1990 to 2021 in Global Burden of Disease (GBD) 2021 database, aiming to provide valuable insights for public health interventions and clinical practices.
Methods: Based on the GBD 2021 database, this study analyzed the incidence, mortality, prevalence, and Disability-Adjusted Life-Years (DALYs) of neuroblastoma and other peripheral nervous system tumors from 1990 to 2021, stratified by sociodemographic development index (SDI) and geographic regions.

Background: Hepatitis B virus (HBV) and hepatitis C virus (HCV) are estimated to be of the most prevalent infectious diseases in correctional settings worldwide. However, viral hepatitis services have not been routinely integrated into South African correctional facilities. We aimed to assess prevalence of HBV infection and HCV infection among people accessing HIV services and assess the feasibility of viral hepatitis service integration in a South African correctional centre.

Chikungunya virus (CHIKV) is primarily associated with non-human-primates (NHPs) in Africa, which also infect humans. Since its introduction to Brazil in 2014, CHIKV has predominantly thrived in urban cycles, involving Aedes aegypti mosquitoes. Limited knowledge exists regarding CHIKV occurrence and implications in rural and sylvatic cycles where neotropical NHPs are potential hosts, from which we highlight Leontopithecus chrysomelas (Kuhl, 1820), the golden-headed lion tamarin (GHLT), an endangered species endemic to the Atlantic Forest (AF) in Southern Bahia State, Brazil.

This study quantifies the impact of COVID-19 vaccination on hospitalization for COVID-19 infection in a South African private health insurance population. This retrospective cohort study is based on the analysis of demographic and claims records for 550,332 individuals belonging to two health insurance funds between 1 March 2020 and 31 December 2022. A Cox Proportional Hazards model was used to estimate the impact of vaccination (non-vaccinated, partly vaccinated, fully vaccinated) on COVID-19 hospitalization risk; and zero-inflated negative binomial models were used to estimate the impact of vaccination on hospital utilization and hospital expenditure for COVID-19 infection, with adjustments for age, sex, comorbidities and province of residence.

The reliability of cardiotocographs as diagnostic tools for fetal well-being is hampered by interpretational variations among healthcare professionals, contributing to high rates of cesarean sections and instrumental deliveries. While adjunct technologies may be used to confirm cases of fetal distress, those in resource constrained areas continue to rely on visual cardiotocograph interpretation to come up with the diagnosis of fetal hypoxia. This study investigated the factors contributing to variations in the visual interpretation of intrapartum cardiotocograph among healthcare professionals in the absence of adjunctive technologies.

Surface water plays a vital role in the spread of infectious diseases. Information on the spatial and temporal dynamics of surface water availability is thus critical to understanding, monitoring and forecasting disease outbreaks. Before the launch of Sentinel-1 Synthetic Aperture Radar (SAR) missions, surface water availability has been captured at various spatial scales through approaches based on optical remote sensing data.

Analyses of the genetic distance and composition of inbred lines are a prerequisite for parental selection and to exploit heterosis in plant breeding programs. The study aimed to assess genetic diversity and population structure of a maize germplasm panel comprising 182 founder lines and 866 derived inbred lines using Single Nucleotide Polymorphism (SNP) markers to identify genetically unique lines for hybrid breeding. The founder lines were genotyped with 1201 SNPs, and the derived lines with 1484 SNPs.

Background: Endometrial cancer is the sixth leading cause of cancer among females and about 97,000 global deaths of endometrial cancer. The changes in the trends of obesity, fertility rates and other risk factors in South Africa (SA) may impact the endometrial cancer trends. The aim of this study was to utilise the age period cohort and join point regression modelling to evaluate the national and ethnic trends in endometrial cancer mortality in South Africa over a 20year period (1999-2018).

Immobility of flowering plants requires them to engage pollen vectors to outcross, introducing considerable inefficiency in the conversion of pollen production into sired seeds. Whether inefficiencies influence the evolution of the relative resource allocation to female and male functions has been debated for more than 40 years. Whereas early models suggested no effect, negative interspecific relations of mean pollen production and pollen : ovule ratios to the proportion of removed pollen that is exported to stigmas (pollen-transfer efficiency) indicate otherwise.

Pollution in marine creeks has been increasing due to anthropogenic activities and has been a global concern. Limited research has been conducted on pharmaceuticals in marine sediment and macroalgae in African countries. In the present study, the levels of pharmaceuticals were assessed in surface sediment and different species of macroalgae (ulvophyceae; Cladophora sudanensis, Chaetomorpha crassa, Chaetomorpha indica, Enteromorpha kylinii, Ulva reticulate, Ulva lactuca and Cladophora sibugae) in Mombasa peri-urban creeks (Tudor, Makupa and Mtwapa creek) and Gazi bay during dry and wet seasons.
