Metabotropic glutamate receptor 5 may be involved in macrophage plasticity

Biol. Res; 50 (), 2017
Abstract Background Macrophages are a functionally heterogeneous cell population and depending on microenvironments they polarize in two main groups: M1 and M2. Glutamic acid and glutamate receptors may participate in the regulation of macrophage plasticity. To investigate the role of glutamatergic sys...

Costo efectividad y análisis de impacto presupuestario del óxido nítrico inhalatorio neonatal en un hospital, desde la perspectiva del sistema público de salud

Rev. chil. pediatr; 87 (6), 2016
El óxido nítrico inhalatorio (ONi) es actualmente la terapia de primera línea en la insuficiencia respiratoria hipoxémica grave del recién nacido; la mayor parte de los centros neonatales de regiones en Chile no cuentan con esta alternativa terapéutica. Objetivo: Determinar el costo-efectividad del...

Anti-inflammatory effect of lycopene on endotoxin-induced uveitis in rats

Arq. bras. oftalmol; 79 (6), 2016
ABSTRACT Purpose: We evaluated the efficacy of lycopene, a dietary carotenoid and potent antioxidant, against ocular inflammation and oxidative stress in an experimental uveitis model. Methods: Endotoxin-induced uveitis (EIU) was induced in Sprague-Dawley rats by a single subcutaneous injection of 200 ...

Inflammatory bowel and oxidative stress changes in an experimental model of portal hypertension: action of N-acetylcysteine

Introduction: Portal hypertension (PH) is characterized by vasodilatation in the portal system and the bowel is one of the severely affected organs. N-acetylcysteine (NAC) is a molecule with important properties and widely used in clinical practice. Objective: To evaluate NAC action in the bowel of anim...

Nutritional supplementation with arginine protects radiation-induced effects. An experimental study

Acta cir. bras; 31 (10), 2016
ABSTRACT PURPOSE: To investigate the protective effect of L-arginine on the prostate (nonneoplasic) of rats with radiation-induced injury. METHODS: Twenty-nine Wistar rats, male adult, allocated into three groups: Control group (C) was not exposed to irradiation (n=10); Radiated group (R) had undergone...

Oral or topical administration of L-arginine changes the expression of TGF and iNOS and results in early wounds healing

Acta cir. bras; 31 (9), 2016
ABSTRACT PURPOSE: To evaluate the contribution of L-arginine oral or topical rout of administration in the surgical wound healing process. METHODS: L-arginine was orally or topically administrated to mice after a laparotomy model procedure. The wounds were analyzed to evaluate the granulation tissue by...

Antioxidant effect of mesalazine in the experimental colitis model induced by acetic acid

Abstract Introduction Inflammatory bowel disease (IBD) is characterized by a chronic inflammation of the gastrointestinal tract, without specific cause or pathogen. Objective The effect of mesalazine in a colitis model induced by acetic acid (AA) was evaluated. Methods We used 40 Wistar rats, ±350 g,...

Is Local Nitric Oxide Availability Responsible for Myocardial Salvage after Remote Preconditioning?

Arq. bras. cardiol; 107 (2), 2016
Abstract Background: Remote ischemic preconditioning (RIPC) represents an attractive therapy for myocardial protection, particularly when ischemic events can be anticipated. Although several hypothetic mechanisms have been proposed, no definite molecular pathways have been elucidated. Objective: We eva...

Ação cardiovascular da peçonha de Bothrops atrox em ratos anestesiados

Bothrops atrox (jararaca-do-norte) é a principal causa de envenenamento ofídico na região amazônica. Vários estudos têm investigado a bioquímica desta peçonha, bem como os efeitos locais (dor, edema, hemorragia e mionecrose) que ela causa. Por outro lado, os efeitos sistêmicos têm sido menos es...

Nitric oxide and asymmetric dimethyl arginine (ADMA) levels in an experimental hydronephrotic kidney caused by unilateral partial ureteral obstruction

Int. braz. j. urol; 42 (3), 2016
ABSTRACT Aim Our aim is to measure asymmetric dimethyl arginine and nitric oxide levels in rats with induced unilateral acute ureteral obstruction to research the effects on the kidney. Material and Methods The study included 21 adolescent (average age 6 weeks) Sprague-Dawley male rats weighing betwe...
