Background: HIV and hepatitis B virus (HBV) coinfection impacts negatively on the prognosis for people living with HIV (PLHIV). HBV is relatively neglected compared to HIV in the South African setting, with limited coinfection seroprevalence data from the Free State.
Objectives: This study aimed to determine the seroprevalence of current and previous HBV in PLHIV in the Free State, South Africa.
Method: In this descriptive cross-sectional study, 1007 residual HIV viral load (VL) samples were selected and screened for markers of current HBV infection (hepatitis B surface antigen [HBsAg]) and previous exposure to HBV (total antibodies to hepatitis B core antigen [HBcTA]) between 01 February 2022 and 31 March 2022. Seroprevalence was assessed for municipal health districts, age, sex, and HIV VL categories.
Results: HBsAg seroprevalence was 6.26% and HBcTA seroprevalence was 36.05%. HBsAg seroprevalence was significantly higher in men at 8.12% as compared to women at 4.38% ( = 0.014). HBcTA seropositivity was also higher in men than in women, at 42.97% for men and 29.08% for women ( < 0.0001). Peak HBsAg and HBcTA positivity was observed among the 40-59-year age group in both men and women. No significant difference was found in HBV seroprevalence and exposure between districts or HIV VL categories.
Conclusion: These findings demonstrate that PLHIV in the Free State, South Africa, fall under the intermediate HBV prevalence category. HBV infection remains a public health concern and emphasis should be placed on identifying and addressing programmatic gaps regarding diagnosis and management.

To surmount the shortcomings of powder-based catalysts and small electrode sizes, the development of meter-scale integrated electrode materials is essential for practical electrocatalytic applications, which requires fine control over the effective surface grafting of catalytic active sites on large-size electrodes as well as addressing the challenge of balancing cost-effective and large-scale manufacturing with highly active and stable operation. Herein, we report a low-cost, facile, and scalable method for directly constructing meter-scale single-molecule-integrated catalytic electrodes using commercially available, flexible, and size-tailored conductive carbon textiles (e.g.

Purpose: After stromal injury to the cornea, the release of growth factors and pro-inflammatory cytokines promotes the activation of quiescent keratocytes into a migratory fibroblast and/or fibrotic myofibroblast phenotype. Persistence of the myofibroblast phenotype can lead to corneal fibrosis and scarring, which are leading causes of blindness worldwide. This study aims to establish comprehensive transcriptional profiles for cultured corneal keratocytes, fibroblasts, and myofibroblasts to gain insights into the mechanisms through which these phenotypic changes occur.

Photocatalytic hydrogen production through water splitting represents a promising strategy to store solar energy as chemical energy. Current photocatalysts primarily focus on traditional semiconductor materials, such as metal oxides, sulfides, nitrides, g-CN, etc. However, these materials often suffer from large bandgap and fast charge recombination, which limit sunlight utilization and result in unsatisfactory photon conversion efficiency.

Advances in neuromicrobiology and related omics technologies have reinforced the idea that unseen microbes play critical roles in human cognition and behaviour. Included in this research is evidence indicating that gut microbes, through direct and indirect pathways, can influence aggression, anger, irritability and antisocial behaviour. Moreover, gut microbes can manufacture chemicals that are known to compromise cognition.

The availability of water-soluble nanoparticles allows catalytic reactions to occur in highly desirable green environments. The catalytic activity and selectivity of water-soluble palladium nanoparticles capped with 6-(carboxylate)hexanethiolate (C6-PdNP) and 5-(trimethylammonio)pentanethiolate (C5-PdNP) were investigated for the reduction of 4-nitrophenol, the oxidation of α,β-conjugated aldehydes, and the C-C coupling of phenylboronic acid. The study showed that between the two PdNPs, C6-PdNP exhibits better catalytic activity for the reduction of 4-nitrophenol to 4-aminophenol in the presence of sodium borohydride and the selective oxidation of conjugated aldehydes to conjugated carboxylic acids.
