Parecoxib mitigates lung ischemia-reperfusion injury in rats by reducing oxidative stress and inflammation and up-regulating HO-1 expression

Acta cir. bras; 36 (9), 2021
ABSTRACT Purpose: To investigate the protective effect of parecoxib against lung ischemia-reperfusion injury (LIRI) in rats and the mechanism. Methods: Thirty rats were divided into sham-operated, LIRI and LIRI+parecoxib groups. LIRI model (ischemia for 60 min, followed by reperfusion for 120 min) was ...

Bacterial pneumonia in captive wild boars in southern Brazil: etiological and pathological causes

Acta sci. vet. (Impr.); 49 (), 2021
Respiratory diseases are one of the major health issues described in intensive pig production, causing important economic losses. However, there is little information on the prevalence, etiology and clinical-pathological presentation of these diseases in wild boars. For this reason, this work investigate...

Tea grape reduces abdominal aortic occlusion-induced lung injury

Abstract Introduction: Ischemia-associated mortality caused by aortic cross-clamps, as in ruptured abdominal aorta aneurysm surgeries, and reperfusion following their removal represent some of the main emergency conditions in cardiovascular surgery. The purpose of our study was to examine the potential ...

Cavidades pulmonares en Lupus Eritematoso Sistémico

Las lesiones pulmonares cavitadas en pacientes con Lupus Eritematoso Sistémico (LES) han sido descriptas en asociación con neumonitis por citomegalovirus, o secundarias a infecciones fúngicas. Haciendo una revisión en la literatura, se han descripto 13 casos de pacientes con estas lesiones. Presentam...

Anti-placental growth factor antibody ameliorates hyperoxia-mediated impairment of lung development in neonatal rats

Braz. j. med. biol. res; 53 (2), 2020
This study investigates the effect of the overexpression of the placental growth factor (PGF) and hyperoxia on lung development and determines whether anti-PGF antibody ameliorates hyperoxia-mediated impairment of lung development in newborn rats. After exposure to normoxic conditions for seven days, new...
