D-ornithine has previously been suggested to enhance the expression of pyrrolysine-containing proteins. We unexpectedly discovered that uptake of D-ornithine results in the insertion of a new amino acid, pyrroline-carboxy-lysine (Pcl) instead of the anticipated pyrrolysine (Pyl). Our feeding and biochemical

Combined administration of ornithine and phenylacetate (OP) is proposed as a novel treatment of hyperammonemia and hepatic encephalopathy. Ornithine is believed to increase ammonia fixation into glutamine in muscle tissue and glutamine is subsequently thought to react with phenylacetate forming

The purpose of immunology is simple. Cure or prevent disease. M1/M2 is useful because it is simple. M1/M2 describes the two major and opposing activities of macrophages. M1 activity inhibits cell proliferation and causes tissue damage while M2 activity promotes

The Frank-Starling law is a fundamental property of the vertebrate myocardium which allows, when the end-diastolic volume increases, that the consequent stretch of the myocardial fibers generates a more forceful contraction. It has been shown that in the eel (Anguilla

Radiolabeled RGD peptides that specifically target integrin α(ν)β(3) have great potential in early tumor detection through noninvasive monitoring of tumor angiogenesis. Based on previous findings of our group on radiopeptides containing positively charged aminoacids, we developed a new cyclic cRGDfK
