We evaluated colitis severity, fatty acid and lipid mediator contents in colonic tissue, and the expression of genes related to lipid mediator formation.\n\nResults: ARA composition of colon phospholipids was significantly elevated in an ARA dose-dependent manner. ARA, as well as DHA, did not affect colitis severity (body weight loss, colon shortening, diarrhea and hemoccult phenomena) and histological features. PGE(2) contents in the colon were unchanged by dietary ARA, while LXA(4) contents increased in an ARA dose-dependent
manner. Gene expression of cyclooxygenase (COX)-1 and COX-2 was unchanged, while that of 12/15-lipoxgenase (LOX) was significantly increased by dietary ARA. ARA composition did not correlate with neither colon length nor PGE(2) contents, but significantly correlated with LXA(4) content.\n\nConclusion: These results suggest that dietary ARA increases EPZ5676 chemical structure ARA and LXA4 contents in colon, but that it has no effect on severity and PGE(2) content in a DSS-induced murine colitis model.”
“Bone integrity is maintained through a balance between bone formation by osteoblasts and bone resorption by osteoclasts. CH5424802 supplier Imbalance of the process results in metabolic bone diseases such as osteoporosis. This study investigated the yellow flag iris extract (YFIE) and revealed its anti-osteoporotic effects in osteoblastic MC3T3-E1 mouse cells and RAW 264.7 murine macrophages. When osteoblasts were treated with 1-20 mu g/ml YFIE in an osteogenic medium, the bone
nodule formation by calcium deposits was markedly enhanced during differentiation. Consistently, YFIE stimulated alkaline phosphatase activity and collagen type I secretion with a substantial effect on osteoblast proliferation. On the other hand, RAW 264.7 macrophages were pre-incubated with 1-20 mu g/ml YFIE for 5 days in the presence of receptor activator of nuclear factor-kappa B ligand Semaxanib mw (RANKL). Non-toxic YFIE markedly attenuated the differentiation of macrophages to multi-nucleated osteoclasts. YFIE diminished RANKL-elevated tartrate-resistant
acid phosphatase activity and bone resorption. In addition, the YFIE treatment retarded RANKL-induced cathepsin K production and carbonic anhydrase II expression, both of which are involved in bone resorption. Therefore, YFIE potentially posesses therapeutic agents that may prevent osteoporosis through promoting bone formation and reducing bone resorption.”
“Epidermolysis bullosa (EB) has officially been recognized as a rare disease in Italy. Regional reference centers for EB have been created during the past years. This article discusses the clinical services and coordinated multidisciplinary management of EB in Italy.”
“A balance trial experiment was carried out to evaluate the potential relationship between an enzymatically hydrolyzed yeast (EHY) and yeast culture combined with a live Bacillus subtilis (Bs) on the productive parameters, ileal digestibility, retention of nutrient and energy and villus morphology in broilers.
