Climate change poses an immediate threat to tropical soils with changes in rainfall patterns resulting in accelerated land degradation processes. To ensure the future sustainability of arable land, it is essential to improve our understanding of the factors that influence soil erosion processes. This work aimed to evaluate patterns of soil erosion using the activity of plutonium isotopes (Pu) at sites with different land use and clearance scale in the Winam Gulf catchment of Lake Victoria in Kenya.

This specialized microvasculature plays a major role in the biology and pathology of the pulmonary vessel walls. We have evidence that thrombosis of the vasa vasorum of the large and medium-sized pulmonary vessels during severe COVID-19 causes ischemia and subsequent death of the pulmonary vasculature endothelium.

- Faecal calprotectin (FC) is a key marker used to assess gut inflammation, particularly in children aged 4-17 with abnormal test results but without established inflammatory bowel disease (IBD).
- The study involved 310 children, where most had FC levels indicating mild inflammation, and a significant percentage with very high levels (500+ μg/g) were eventually diagnosed with IBD or had infectious diarrhea.
- The findings suggest that while many children had elevated FC levels, they were mostly below the threshold for mucosal inflammation, highlighting the potential of repeat FC testing for better diagnosis.
