Int J Gynaecol Obstet

January 2025

Department of Obstetrics and Gynaecology, Faculty of Health Sciences, University of Pretoria, Pretoria, South Africa.

Background: Female sterilization, a safe, permanent method of contraception that blocks the fallopian tubes, has been in use since the 19th century. The procedure necessitates informed consent, a critical step that has been marred by reports of forced sterilization since World War II. These incidents often stem from inadequate consent processes where ethical principles are overlooked or deliberately flouted.

High-volume disease (HVD) and low-volume disease (LVD) definitions in metastatic hormone-sensitive prostate cancer (mHSPC) patients are based on conventional imaging (CI) (CT/MRI with bone scan [BS]) according to CHAARTED criteria. HVD and LVD definitions are associated with overall survival and are used for treatment decisions. It remains unknown how these definitions transfer to prostate-specific membrane antigen (PSMA) PET imaging.

Genetic variability in snake venom and its implications for antivenom development in sub-Saharan Africa.

Trans R Soc Trop Med Hyg

January 2025

Pharm-Biotechnology and Traditional Medicine Centre (PHARMBIOTRAC), Faculty of Medicine, Mbarara University of Science and Technology, Mbarara 40006, Uganda.

Snake venom, a complex mixture of proteins, has attracted human attention for centuries due to its associated mortality, morbidity and other therapeutic properties. In sub-Saharan Africa (SSA), where snakebites pose a significant health risk, understanding the genetic variability of snake venoms is crucial for developing effective antivenoms. The wide geographic distribution of venomous snake species in SSA countries demonstrates the need to develop specific and broad antivenoms.

Objective: The aim was to investigate the patellar ligament strain with varying degrees of tibial plateau angles (TPAs) after tibial plateau leveling osteotomy (TPLO) in a cranial cruciate ligament (CrCL)-deficient stifle during the stance phase.

Methods: 12 pelvic cadaver limbs were secured to a custom-built jig to mimic a loadbearing stance after which an axial load of 120 N was applied. Patellar ligament strain, change in strain, and percent change in strain were calculated on pre-TPLO (intact and transected CrCL) and post-TPLO tibial TPAs of -5°, 0°, 5°, 10°, and 15°.

Bovine brucellosis and bovine tuberculosis are zoonotic diseases with economic and public health importance across the world, especially in developing countries where the diseases are endemic. The diseases are classified as neglected diseases in developing nations with poor resources despite good control measures in some developed countries. The purpose of this study is to assess the knowledge, attitudes and perceptions (KAP) of stakeholders towards control measures for bovine brucellosis (BR) and bovine tuberculosis (bTB) at a livestock-wildlife interface.

Indigenous chickens are an important Farm Animal Genetic Resource (FAnGR) in South Africa as they alleviate poverty and are a source of protein. Climate change and market demand for high-performing exotic breeds threaten and undermine locally adapted village chickens. The current study explored the risk status and signatures of adaptation of village-based indigenous chickens from two provinces and mapped their environmental suitability across the country.

Landfilling is common in developing countries since it is the easiest and cheapest way of waste disposal, however, it leads to serious environmental problems such as soil, water, and air pollution. A landfill has a life span of fifteen years after which it is closed leaving the site unusable, as a result, effective methods are needed for restoring and reclaiming the closed landfill site for future use. Phytoremediation has emerged as a viable and environmentally friendly method, which uses green plants to remove pollutants from soil, air, and water.

Electronic address:

Owing to the long duration of cooking legumes, which limits their consumption and utilization, soaking has been used to reduce cooking time, save energy consumption, and diminish their hardness. However, limited studies have reported the influence of cooking and soaking treatment along with ultrasonication on hydration, hardness, and cooking time reduction of legumes. Therefore, this study investigated the impact of cooking and soaking treatments on Dr.

Understanding the genetics of sex determination in insects and its relevance to genetic pest management.

Insect Mol Biol

December 2024

Department of Zoology and Entomology, Forestry and Agricultural Biotechnology Institute (FABI), University of Pretoria, Pretoria, South Africa.

Sex determination pathways regulate male and female-specific development and differentiation and offer potential targets for genetic pest management methods. Insect sex determination pathways are comprised of primary signals, relay genes and terminal genes. Primary signals of coleopteran, dipteran, hymenopteran and lepidopteran species are highly diverse and regulate the sex-specific splicing of relay genes based on the primary signal dosage, amino acid composition or the interaction with paternally inherited genes.
