... with a decline of caries. Another approach in preventing caries might be the increase of pH in dental plaque. During recent years, arginine has increasingly become the focus of interest. This is based on the fact that certain streptococci possess an arginine deiminase system (ADS) which metabolizes free arginine...

... Abstract Recent studies suggest that alterations of the arginine metabolome and a dysregulation of nitric oxide (NO) homeostasis play a role in the pathogenesis of asthma. <smlcap>L</smlcap>-Arginine, a semi-essential amino acid, is a common substrate for both the arginases...

... Abstract Arginine is an important amino acid during disease and healing because of functions in the immune system and as precursor of nitric oxide (NO). In critically ill adults and children, plasma arginine and citrulline concentrations are substantially decreased, indicating an arginine...

... Abstract Dietary arginine supplementation has been suggested as a means of improving T lymphocyte function and has found its greatest clinical utility in patients undergoing elective surgery. In other illnesses, arginine supplementation is controversial. Breakthroughs in understanding arginine...

... vasodilatation, blood flow, mitochondrial respiration and platelet function. <smlcap>l</smlcap>-Arginine is the main precursor of NO via nitric oxide synthase (NOS) activity. Additionally, <smlcap>l</smlcap>-citrulline has been indicated to be a second NO donor in the NOS-dependent...

... Abstract SummaryIn 1977, Rogers, Harding, and Llewellyn-Smith described an enzymic activity in hair follicles which has the property of converting arginine to citrulline in situ in proteins. The protein precursor substrate in the hair follicle was identified as trichohyalin in the inner root...
