The effect on the blood lead levels of residents in an area in which a soft plumbo-solvent water was hardened is examined. Water lead levels fell after hardening was introduced whereas there was a small rise in water lead levels in a control area monitored over the same time. The blood lead levels of residents fell after hardening and the fall was slightly greater than would have been predicted on the basis of the change in water lead levels. This suggests that lead is less well absorbed from hard water than from soft water. Following hardening there was a significant fall in mean blood lead level of subjects living in houses which had initially had negligible amounts of lead in the water. This suggests that hard water may interfere with the absorption of lead from sources other than water.

Defective Slc7a7 transport reduces erythropoietin compromising erythropoiesis.

Background: Lysinuric protein intolerance is a rare autosomal disorder caused by mutations in the Slc7a7 gene that lead to impaired transport of neutral and basic amino acids. The gold standard treatment for lysinuric protein intolerance involves a low-protein diet and citrulline supplementation. While this approach partially improves cationic amino acid plasma levels and alleviates some symptoms, long-term treatment is suggested to be detrimental and may lead to life-threatening complications characterized by a wide range of hematological and immunological abnormalities.

Plastic pollution and global warming are widespread issues that lead to several impacts on aquatic organisms. Despite harmful studies on both subjects, there are few studies on how temperature increases plastics' adverse effects on aquatic animals, mainly freshwater species. So, this study aims to clarify the potential impact of temperature increases on the toxicological properties of polyvinyl chloride nano-plastics (PVC-NPs) in Nile tilapia (Oreochromis niloticus) by measuring biochemical and oxidative biomarkers.

The utilization of cyanobacteria toxin-producing blooms for metal ions adsorption has garnered significant attention over the last decade. This study investigates the efficacy of dead cells from Microcystis aeruginosa blooms, collected from agricultural drainage water reservoir, in removing of cadmium, lead, and zinc ions from aqueous solutions, and simultaneously addressing the mitigation of toxin-producing M. aeruginosa bloom.

Background: Sexually transmitted infections (STIs) are a significant global health challenge, demanding attention and intervention. Despite many STIs being manageable, their asymptomatic nature poses a formidable threat to both mental and physical well-being. This silent impact can lead to substantial morbidity and mortality, which is particularly pronounced in East Africa.
