Exenatide ameliorates hepatic steatosis and attenuates fat mass and FTO gene expression through PI3K signaling pathway in nonalcoholic fatty liver disease

Braz. j. med. biol. res; 51 (8), 2018
Non-alcoholic fatty liver disease (NAFLD) is a common disease associated with metabolic syndrome and can lead to life-threatening complications like hepatic carcinoma and cirrhosis. Exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist antidiabetic drug, has the capacity to overcome insulin resis...

Acute exercise inhibits gastric emptying of liquids in rats: influence of the NO-cGMP pathway

Braz. j. med. biol. res; 51 (11), 2018
We previously found that acute exercise inhibited the gastric emptying of liquid in awake rats by causing an acid-base imbalance. In the present study, we investigated the involvement of the nitric oxide-cyclic guanosine monophosphate (NO-cGMP) pathway, vasoactive intestinal peptide (VIP), and corticotro...

Effects of a Single Bout of Resistance Exercise in Different Volumes on Endothelium Adaptations in Healthy Animals

Arq. bras. cardiol; 108 (5), 2017
Abstract Background: Resistance exercise (RE) has been recommended for patients with cardiovascular diseases. Recently, a few studies have demonstrated that the intensity of a single bout of RE has an effect on endothelial adaptations to exercise. However, there is no data about the effects of different...

Effects of nitric oxide inhibitors in mice with bladder outlet obstruction

Int. braz. j. urol; 43 (2), 2017
ABSTRACT Purpose To investigate the lower urinary tract changes in mice treated with L-NAME, a non-selective competitive inhibitor of nitric oxide synthase (NOS), or aminoguanidine, a competitive inhibitor of inducible nitric oxide synthase (iNOS), after 5 weeks of partial bladder outlet obstruction (B...

Busca de alvos proteicos para desenvolvimento de inibidores enzimáticos em sistemas hospedeiro-parasito

Diante da necessidade de uma metodologia para buscar e avaliar a relevância do desenvolvimento de inibidores para enzimas específicas em um organismo patógeno que pudesse ser aplicada em sistemas hospedeiro-parasito em geral foram utilizados dois modelos; um envolvendo um vertebrado, Homo sapiens, e u...

Local inhibition of nitrergic activity in tenotomized rats accelerates muscle regeneration by increasing fiber area and decreasing central core lesions

Braz. j. med. biol. res; 50 (3), 2017
Muscular atrophy is a progressive degeneration characterized by muscular proteolysis, loss of mass and decrease in fiber area. Tendon rupture induces muscular atrophy due to an intrinsic functional connection. Local inhibition of nitric oxide synthase (NOS) by Nω-nitro-L-arginine methyl ester (L-NAM...

Absorption mechanism of three curcumin constituents through in situ intestinal perfusion method

Braz. j. med. biol. res; 50 (11), 2017
This study aimed to investigate the absorption mechanism of three curcumin constituents in rat small intestines. Self-emulsification was used to solubilize the three curcumin constituents, and the rat in situ intestinal perfusion method was used to study factors on drug absorption, including drug mass co...

Aqueous extract of Psidium guajava leaves: phenolic compounds and inhibitory potential on digestive enzymes

An. acad. bras. ciênc; 89 (3,supl), 2017
ABSTRACT Leaves of Psidium guajava L. (guava) have been widely used in the popular way for prevention and treatment of various diseases. Thus, the objective of this study was to evaluate the inhibitory potential of leaves aqueous extract from three cultivars of P. guajava (Pedro Sato, Paluma and Século ...

Hepatotoxicity and nephrotoxicity of 3-bromopyruvate in mice

Acta cir. bras; 31 (11), 2016
ABSTRACT PURPOSE: To investigate the hepatotoxicity and nephrotoxicity of 3-Bromopyruvate (3BP) in mice. METHODS: Fifteen nude mice were grafted subcutaneously in the left flank with MDA-MB-231 cells, then all mice were divided into control group (PBS), 3BP group (8 mg/kg), positive group (DNR: 0.8 mg/...

Effect of S-methyl-l-thiocitrulline dihydrochloride on rat micturition reflex

Int. braz. j. urol; 42 (5), 2016
ABSTRACT Objective: To evaluate the effect of neuronal nitric oxide synthase on the striated urethral sphincter and the urinary bladder. Materials and Methods: A coaxial catheter was implanted in the proximal urethra and another one in the bladder of female rats, which were anesthetized with subcutaneo...
