Alterations in neuronal nitric oxide (NO) production may play a role in the pathophysiology of Parkinson's disease (PD) Alzheimer's disease (AD), and multiple system atrophy (MSA). The biosynthesis of NO is dependent on the availability of L-arginine, the substrate for NO-synthase (NOS), and on
Post-polio syndrome (PPS) is a condition that affects polio survivors years after recovery from an initial acute infection by the Poliomyelitis virus. Most often, patients who suffered from polio start to experience gradual new weakening in muscles, a gradual decrease in the size of muscles (muscle
Duchenne muscular dystrophy (DMD) is an X-linked recessive disease that affects 1 in 3500-6000 male births. Despite broad research aiming to improve muscle function as well as heart and brain function, sufficient therapeutic efficacy has not yet been achieved and current therapeutic management is
There is an increasing evidence that oxidative stress plays an important role in the pathogenesis of rhabdomyolysis-induced acute renal failure (ARF). In this study, protective effects of L-citrulline on glycerol-induced ARF in rats were investigated. Six groups of rats were employed in this study:
Nitric oxide precursors, such as the amino acid l-arginine and the biguanide antidiabetic drug metformin, have been associated with metabolism and muscle function in patients with Duchenne muscular dystrophy (DMD). The treatment of DMD remains an unmet medical L-citrulline is an organic α-amino acid that has been shown to produce a number of salutary actions on whole-body physiology, which includes reducing muscle wasting and augmenting exercise/muscle performance. The latter has been suggested to arise from elevations in mitochondrial function. Because
Nitric oxide, a simple gas which serves as a neurotransmitter in the CNS, has been proposed to serve as an interneuronal second messenger in olfactory transduction. However, the role of nitric oxide in olfaction has been questioned by experiments in which nitric oxide synthase, the enzyme that
Excessive NO produced by an inducible NO synthase (iNOS) has been implicated in many types of immune-associated disorders of the cardiovascular system, but it remains to be determined whether NO plays a role in myocarditis. Thus, the significance of iNOS expression in the development of experimental
OBJECTIVE
Administration of high doses of amino acids like ethionine, methionine, and arginine causes pancreatic tissue damage. The initial mechanism behind these effects is not known. The aim of this study was to show the early effects of a load of L-arginine on programed cell death/proliferation
BACKGROUND
Plasma citrulline is not incorporated in endogenous or exogenous proteins so it is a theoretical marker of villous atrophy. Our aim was to correlate plasma citrulline levels with severity of villous atrophy in celiac patients.
METHODS
Observational case-control study longitudinal in
1. Brief interruption of spinal cord blood flow resulting from transient abdominal aortic occlusion may lead to degeneration of specific spinal cord neurons and to irreversible loss of neurological function. The alteration of nitric oxide/nitric oxide synthase (NO/NOS) pool occurring after ischemic
Nitric oxide (NO) has emerged as a novel regulator of several ovarian events, such as ovulation, steroidogenesis, and apoptotic cell death. The NO synthases (NOS) are a family of enzymes that catalyze the oxidation of L-arginine to NO and L-citrulline. The purpose of the present study was to
