Cardiac solution for a vascular scenario!

Background: Ascending aortic pseudoaneurysms (AAPs) constitute a rare, albeit potentially dangerous, condition that occurs in up to 13% of patients after cardiac or aortic surgeries. For patients with a history of cardiac surgery, repeat thoracotomy poses additive risks. The high morbidity and mortality rates associated with the surgical management of AAPs have led to the development of transcatheter approaches.

Protective Effects of N-Acetyl-L-Cysteine on the Density of Spiral Ganglion Cells and Histological Changes Induced by Continuous Noise Exposure in Rats.

Background: Noise exposure causes loss of cochlea hair cells, leading to permanent sensorineural hearing loss, and initiates pathological changes to the bipolar primary auditory neurons (ANs). This study focuses on the effects of N-acetyl-l-cysteine (NAC) in protecting the density of spiral ganglion cells and in histological changes induced by continuous noise exposure in rats.

Methods: Twenty-four male Wistar rats were randomly allocated into four experimental groups to receive NAC, saline, noise, or both noise and NAC.

Effect of exercise on serum adiponectin and lipoprotein levels in male rat.

The effect of exercise and recovery period on adiponectin level is not still cleared. The aim of this study was to evaluate the effect of different intensities of running on serum adiponectin and lipoproteins levels in male rats. In this experimental study, one hundred and sixty rats aged 2 months years old (250 +/- 5 g) were randomly assigned into four groups including the control and the 3 groups running at the speeds of 18, 24 and 30 m min(-1) for 30 min.
