Melatonin ameliorates H2O2-induced oxidative stress through modulation of Erk/Akt/NFkB pathway

Biol. Res; 51 (), 2018
BACKGROUND: Improper control on reactive oxygen species (ROS) elimination process and formation of free radicals causes tissue dysfunction. Pineal hormone melatonin is considered a potent regulator of such oxidative damage in different vertebrates. Aim of the current communication is to evaluate the leve...

Transection of the hepatic parenchyma associated or not with the contralateral portal vein branch ligature and its effect in liver regeneration

Einstein (Säo Paulo); 15 (2), 2017
ABSTRACT Objective To analyze the influence of portal vein ligation in hepatic regeneration by immunohistochemical criteria. Methods Ten pigs divided into two groups of five animals underwent hepatectomy in two stages, and the groups were differentiated by ligation or not of the left portal vein trib...

Management Strategies for Liver Fibrosis

Ann. hepatol; 16 (1), 2017
Abstract: Liver fibrosis resulting from chronic liver injury are major causes of morbidity and mortality worldwide. Among causes of hepatic fibrosis, viral infection is most common (hepatitis B and C). In addition, obesity rates worldwide have accelerated the risk of liver injury due to nonalcoholic fatt...

Uptake of DNA by cancer cells without a transfection reagent

Biol. Res; 50 (), 2017
BACKGROUND: Cancer cells exhibit elevated levels of glucose uptake and may obtain pre-formed, diet-derived fatty acids from the bloodstream to boost their rapid growth; they may also use nucleic acid from their microenvironment. The study of processing nucleic acid by cancer cells will help improve the u...

The effect of the aqueous extract Peumus boldus on the proliferation of hepatocytes and liver function in rats submitted to expanded hepatectomy

Acta cir. bras; 31 (9), 2016
ABSTRACT PURPOSE: To assess the effect of aqueous extract of Peumus Boldus (AEPB) on the liver proliferative response after parcial hepatectomy of 70% (PH) in rodents. METHODS: Twenty Wistar rats were divided in two groups: AEPB100 (whose rats received 100mg/Kg of AEPB, once a day, orally, in 4 days pr...

Sox2 function as a negative regulator to control HAMP expression

Biol. Res; 48 (), 2015
BACKGROUND: Hepcidin, encoding by HAMP gene, is the pivotal regulator of iron metabolism, controlling the systemic absorption and transportation of irons from intracellular stores. Abnormal levels of HAMP expression alter plasma iron parameters and lead to iron metabolism disorders. Therefore,itis animpo...
