Gene expression profile of oxidative stress in the lung of inbred mice after intestinal ischemia/reperfusion injury.

Purpose: To determine the gene expression profile associated with oxidative stress and antioxidant defense in the lung tissue of mice subjected to intestinal ischemia and reperfusion.

Methods: Twelve male, inbred mice (C57BL/6) were randomly assigned to one of two groups. The control group (CG) underwent anesthesia and laparotomy and was observed for 120 minutes; the ischemia/reperfusion group (IRG) was subjected to anesthesia, laparotomy, and ischemia of the small intestine for 60 minutes and to 60 minutes of reperfusion.

Serology with ML Flow test in health professionals from three different states of Brazil.

Background: In highly endemic countries, transmission and sub-clinical infection of leprosy are likely and the disease manifests itself in individuals without any known close contact with a leprosy patient. Health workers are social contacts belonging to the same network (the Health System) and some of them share the same social environment (nursing assistants) as patients with known patients and / or carriers.

Objective: To identify ML Flow seropositivity among health professionals.

Genotoxic and mutagenic effects of diflubenzuron, an insect growth regulator, on mice.

This study assessed the genotoxic and mutagenic potential of diflubenzuron (DFB) insecticide in mice. Mice were divided into five groups: group I: negative control; group II: positive control; group III: 0.3 mg/kg of DFB; group IV: 1 mg/kg of DFB; group V: 3 mg/kg DFB.

Maternal exposure to aqueous extract of Jacaranda decurrens: effects on reproductive system in male rats.

Context: Jacaranda decurrens subsp. symmetrifoliolata Farias & Proença (Bignoniaceae) is a species widely used for their medicinal properties. At least to our known, no study has been conducted concerning its toxicological profile after gestational and lactational exposure.
