OBJECTIVE
Studies have shown that the circulating citrulline concentration is decreased in patients with proximal small bowel villous atrophy from coeliac disease and more so in patients with extensive damage to the intestinal mucosa, but there have been few data on HIV enteritis and tropical
OBJECTIVE
Plasma citrulline, a nitrogen end product of glutamine metabolism in small-bowel enterocytes, was suggested as a marker of radiation-induced small-bowel epithelial cell loss in mice after single-dose whole-body irradiation. Our objective was to evaluate the feasibility of citrulline as a
OBJECTIVE
Plasma citrulline, a nonprotein amino acid produced by enterocytes, was suggested as a marker of remnant enterocyte mass in patients with short bowel. Our objective was to evaluate citrulline as a marker of severity and extent of villous atrophy in patients without intestinal
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
Plasma citrulline is decreased in cases of severe intestinal injury with apparent villus and cellular atrophy. However, the fluctuation of plasma citrulline in slight intestinal injury remains to be investigated. To clarify this, irinotecan at 30 mg/kg or 60 mg/kg was administered intravenously to
Intense seizure activity associated with status epilepticus and excitatory amino acid (EAA) imbalance initiates oxidative damage and neuronal injury in CA1 of the ventral hippocampus. We tested the hypothesis that dendritic degeneration of pyramidal neurons in the CA1 hippocampal area resulting from
Arginine homoeostasis is impaired in short bowel syndrome, but its supplementation in short bowel syndrome patients remains controversial. Recently, we demonstrated the benefits of citrulline supplementation by the enteral route in resected rats. Since the first step in managing short bowel syndrome
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
Deficiency of ornithine-δ-aminotransferase (OAT) in humans results in gyrate atrophy. Early diagnosis may allow initiation of treatment before irreversible damage has occurred. However, diagnosis is commonly delayed well into adulthood because of the nonspecific character of initial symptoms. Here,
OBJECTIVE
Glutamine is the preferred fuel for the rat small intestine and promotes the growth of intestinal mucosa, especially in the event of gut injury. Quantitatively, glutamine is one important precursor for intestinal citrulline release. The aim of this study was to determine whether the effect
OBJECTIVE
To investigate inducible nitric oxide synthase(iNOS) activity of retina and the effects of N(omega)-nitro-L-arginine(N-Arg) on photoreceptor apoptosis in inherited retinal degeneration of Royal College of Surgeons (RCS) rats.
METHODS
iNOS activity was assayed in the whole retinal
We investigated serum homocysteine, arginine, citrulline and asymmetric dimethyl arginine (ADMA) levels and conducted a histopathologic examination of the abdominal aorta in rats given acrylamide (AA) for long periods. We used 25 male and 25 female Wistar rats. Females were divided into three
To investigate the role of nitric oxide in the cerebellar degeneration during methylmercury intoxication, interaction of the change in nitric oxide synthase activity and degeneration of the granular layer neurons was examined in rats after methylmercury administration. Both reduced nicotinamide
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
