New determinants for casual peripheral mechanism of neurogenic lung edema in subarachnoid hemorrhage due to ischemic degeneration of vagal nerve, kidney and lung circuitry. Experimental study

Acta cir. bras; 34 (3), 2019
Abstract Purpose: To evaluate whether there is a relationship between renal artery vasospasm related low glomerular density or degeneration and neurogenic lung edema (NLE) following subarachnoid hemorrhage. Methods: This study was conducted on 26 rabbits. A control group was formed of five animals, a ...

Anatomical and clinical aspects of horseshoe kidney: a review of the current literature

Int. j. morphol; 37 (1), 2019
SUMMARY: Horseshoe kidney (HSK) is the most common kidney malformation. This review analyses the literature surrounding the etiology, morphology and clinical anatomy of these kidney fusion anomalies. A systematic literature search was carried out using the Science Direct and Scopus applications. HSK is c...

Effects of cyclosporine on ischemia-reperfusion injuries in rat kidneys. An experimental model

Acta cir. bras; 34 (8), 2019
Abstract Purpose To assess Cyclosporine A (CsA) therapy at an intraperitoneal dose of 15 mg.kg -1 in a rodent model of non-septic renal ischemia. Methods Twenty male Wistar rats were randomized to receive CsA therapy or none therapy before undergoing 30 minutes of renal ischemia followed by reperfusion...

Muscle changes with high-intensity aerobic training in an animal model of renal disease

Acta cir. bras; 34 (5), 2019
Abstract Purpose: To analyze the muscle changes with high-intensity aerobic training (HIAT) in an animal model of renal disease (RD). Methods: Twenty one adult Wistar rats were divided into 3 groups: healthy sedentary (HS), RD sedentary (RDS), RD aerobic training (RDAT). RDS and RDAT were subjected to ...

Expression analysis of long non-coding RNAs in a renal ischemia-reperfusion injury model

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To investigate the long non-coding RNAs (lncRNAs) profile on renal ischemia reperfusion in a mouse model. Methods: Microarray analysis was used to study the expression of misregulated lncRNA in a mouse model of renal ischemia reperfusion(I/R) with long ischemia time. Quantitative re...

Inflammation and kidney injury attenuated by prior intake of Brazil nuts in the process of ischemia and reperfusion

J. bras. nefrol; 40 (4), 2018
ABSTRACT Introduction: Ischemia and reperfusion (IR) is a process inherent to the procedures involved in the transplantation of organs that causes inflammation, cell death and cell injury, and may lead to rejection of the graft. It is possible that the anti-inflammatory properties of the Brazil nuts (BN...

Adipose tissue derived mesenchymal stem cell transplantation in the treatment of ischemia/reperfusion induced acute kidney injury in rats. Application route and therapeutic window

Acta cir. bras; 33 (11), 2018
Abstract Purpose: To evaluate renal repair in rats who had renal infarction induced by the obstruction of blood flow in the renal artery and were treated with transplantation of adipose tissue derived mesenchymal stem cell Methods: 16-week-old Wistar rats (n=72) were used, submitted to celiotomy and ha...

The preoperative stratification of patients based on renal scan data is unable to predict the functional outcome after partial nephrectomy

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Introduction: eGFR-categories are used to predict functional outcome after partial nephrectomy (PN); no study categorized patients according to preoperative renal scan (RS) data. Aim of the study was to evaluate if stratification of patients according to RS is a reliable method to predict minor...

Effects of remote ischemic preconditioning and topical hypothermia in renal ischemia-reperfusion injury in rats

Acta cir. bras; 33 (5), 2018
Abstract Purpose: To evaluate whether combining hypothermia and remote ischemic preconditioning (RIPC) results in protection from ischemia-reperfusion (IR). Methods: Thirty-two Wistar rats underwent right nephrectomy and were randomly assigned to four experimental protocols on the left kidney: warm isc...

Combined effects of melatonin and topical hypothermia on renal ischemia-reperfusion injury in rats

Acta cir. bras; 33 (3), 2018
Abstract Purpose: To evaluate whether their combination was more effective than either alone in decreasing renal damage due to ischemia/reperfusion (I/R) injury in rats. Methods: Thirty-two Wistar rats were assigned to four groups. Following right nephrectomy, their left kidneys were subjected to warm...
