Topic: The systematic review and meta-analysis consolidates the extant body of evidence comparing reliability and agreement between Transpalpebral Tonometers (TT) and Goldmann Applanation Tonometer (GAT).
Clinical Relevance: With a global prevalence of 3.54 percent, glaucoma stands as the second leading cause of preventable blindness.
Urban landscapes are high phosphorus (P) consumption areas and consequently generate substantial P-containing urban solid waste (domestic kitchen wastes, animal bones, and municipal sludge), due to large population. However, urbanization can also trap P through cultivated land loss and urban solid waste disposal. Trapped urban P is an overlooked and inaccessible P stock.

- - Agricultural systems are significant contributors to global nitrous oxide (NO) emissions, largely due to over-fertilization and antibiotic residues, prompting global concern about environmental impacts.
- - Research focused on how ciprofloxacin (CIP) increases NO production in soils by altering microbial processes, revealing that exposure leads to a shift from nitrification to denitrification and increases certain bacteria that produce NO.
- - The study identifies a specific strain, Methylobacillus flagellatus KT, which can produce NO while also breaking down CIP, suggesting it uses CIP byproducts as food and highlighting its role in both NO emission and antibiotic degradation in soil ecosystems.
Pepper (Capsicum spp.) is an important fruit vegetable worldwide, and it is a rich dietary source of minerals for human being. Yet, the spatio-temporal distribution of pepper fruit mineral composition and the factors influencing such variations at global scale remain unknown.
View Article and Find Full Text PDFThe land application of livestock manure has been widely acknowledged as a beneficial approach for nutrient recycling and environmental protection. However, the impact of residual antibiotics, a common contaminant of manure, on the degradation of organic compounds and nutrient release in Eutric Regosol is not well understood. Here, we studied, how oxytetracycline (OTC) and ciprofloxacin (CIP) affect the decomposition, microbial community structure, extracellular enzyme activities and nutrient release from cattle and pig manure using litterbag incubation experiments.
