Article Synopsis
- * Researchers examined biochar made from peanut shells as a soil enhancer to improve broad bean cultivation during drought, finding it increased soil water holding capacity by 66% and organic matter by 220%.
- * The application of this biochar positively impacted plant growth, enhancing metrics such as stem height and pod weight, while also showing correlations between plant physiological responses and soil properties, suggesting its potential for sustainable agricultural practices.
Objectives: To evaluate the nutritional quality and microbial contamination of raw camel milk sourced from street vendors and compare it with milk obtained from farms, with a particular emphasis on pathogenic organisms.
Methods: Twenty samples were systematically collected from street vendors and farms between July 2022 and February 2023 and analyzed at King Fahad Medical Research Centre and the Pharmacy College, King Abdulaziz University, Jeddah, Saudi Arabia. The microbial analysis employed culture-dependent techniques for colony-forming unit analysis and isolation of microbial colonies from milk samples.
Article Synopsis
- Trypanosomosis caused by Trypanosoma evansi (surra) significantly affects camel health and production, prompting an investigation into its immunological impact on blood leukocytes.
- The study compared leukocyte populations and lymphocyte subsets between healthy camels and those with chronic surra, revealing a higher leukocyte count and reduced B cells in diseased camels.
- In vitro tests showed that T. evansi has a strong affinity for camel B cells, leading to their death through apoptosis and necrosis, highlighting the disease's immunosuppressive effects.
D-galactose (D-gal) administration was proven to induce cognitive impairment and aging in rodents' models. Geraniol (GNL) belongs to the acyclic isoprenoid monoterpenes. GNL reduces inflammation by changing important signaling pathways and cytokines, and thus it is plausible to be used as a medicine for treating disorders linked to inflammation.

Methods: The questionnaire was subjected to a rigorous evaluation process, which included a literature review and focus groups comprising the general public, FSS, and key experts in food service. The pilot testing highlighted its utility and determined its content validity ratio (CVR).
