citrulline/necrosis

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

Nitric oxide has been implicated as one possible mediator of interleukin-1 beta (IL-1)-induced inhibition of insulin secretion and islet cell damage. The aim of this study was to define the effects of tumor necrosis factor-alpha (TNF) and interferon-gamma (IFN) on nitric oxide production, insulin

We recently demonstrated that citrulline (CIT) reduced the expression of inflammatory genes in cultured explants from retroperitoneal (RET) white adipose tissue (WAT) from young (2-4 months) but not old (25 months) rats. Here we show that in RET WAT from old rats and high-fat-diet-fed (HFD) young

Nitric oxide (NO) has been implicated in many physiological and pathological conditions in the eyes. The induction of inducible NO synthase (iNOS) and NO production have been noted in immunostimulated retinal pigment epithelial (RPE) cells. Cellular NO production depends on the availability of

OBJECTIVE Hypocitrullinemia has been suggested to be a prognostic factor for patients in intensive care. The aim of this ancillary study of the Corticosteroids and Intensive Insulin Therapy for Septic Shock prospective study was to investigate plasma L-citrulline concentrations and its relationship

1. This study investigates the role of tumour necrosis factor (TNF) in the induction of nitric oxide synthase (NOS) by bacterial endotoxin (lipopolysaccharide; LPS) in a rat model of endotoxin shock. 2. In anaesthetized rats, pretreatment with a monoclonal antibody for TNF (TNFab; 20 mg kg-1, s.c.,

Human recombinant arginase I cobalt coupled to polyethylene glycol 5000 (HuArg I [Co]-PEG5000) achieved potent in vitro depletion of arginine from tissue culture medium and cytotoxicity to many cancer cell lines. The recombinant enzyme also produced tumor growth inhibition of hepatocellular

Citrulline has anti-inflammatory properties and exerts beneficial effects on various impaired functions in aging. However, there are few data on citrulline action on immune function in aged populations. The objective of the study was to evaluate citrulline ability, after in vivo and in vitro

Various functions of human phagocytes are modulated by nitric oxide (NO). We transfected the human U937 monoblastoid cell line with an expression vector containing human endothelial NO synthase (eNOS) or murine inducible NOS (iNOS) cDNA to study the regulatory role of NO without the nonspecific

OBJECTIVE Gastrointestinal (GI) mucositis is a severe adverse effect of chemotherapy and radiotherapy. Proinflammatory cytokines are thought to play an important role in the pathophysiology of GI mucositis. We aimed to determine the effect of the tumor necrosis factor-alpha (TNF-α) inhibitor

Tumor necrosis factor-alpha (TNF-alpha) is a pleiotropic cytokine that markedly affects neuroendocrine functions. This cytokine is expressed in the anterior pituitary where its receptors are also present. Nitric oxide (NO) is synthesized in gonadotropes and folliculo-stellate cells of the anterior

The administration of endotoxins to rats as lipopolysaccharides (LPS) induces a state of exhaustion, in which the main symptoms are febrile hyperthermia, reduced food intake, decreased body weight, and reduced muscle performance in treadmill tests. Underlying the physiological and behavioral
