Testing alternatives: the use of adipose-derived mesenchymal stem cells to slow neurodegeneration in a rat model of Parkinson's disease.

Parkinson's disease (PD) is a chronic neurodegenerative disease. Unfortunately, the effectiveness of anti-Parkinson treatments gradually diminishes owing to the progressive degeneration of the dopaminergic terminals. The research described here investigated the effect of adipose-derived mesenchymal stem cells (AD-MSC) versus that of an anti-Parkinson drug in a rat model of Parkinsonism.

Cardiac histopathological and immunohistochemical changes due to electric injury in rats.

It has been a puzzling forensic task to determine the cause of death as a result of electric shock in the absence of recognizable skin marks or definite postmortem morphological findings. In forensic pathology, while classical macroscopic and microscopic morphology remain core procedures to investigate deaths, a variety of subsidiary measures has been developed and incorporated to detail that pathology. C-fos, one of a small group of genes called primary response genes and its protein product, fos, are crucial elements of complex signaling mechanisms believed to be responsible for cell response to stimulation.

Correlation between seminal lead and cadmium and seminal parameters in idiopathic oligoasthenozoospermic males.

Introduction: The exact causes of the decline in semen quality are not yet known, environmental factors have been considered to play an important role. Lead (Pb) and Cadmium (Cd) are two of the well-known reproductive toxicants to which humans are exposed occupationally and environmentally and can lead to negative effects on the testicular functions. The aim of this study was to evaluate lead and cadmium levels in seminal plasma of men with idiopathic oligoasthenozoospermia in comparison to fertile healthy controls and to correlate these levels with conventional semen parameters, sperm hypo-osmotic swelling (HOS) percentage, sperm DNA fragmentation percentage, and semen reactive oxygen species (ROS) levels.

Effect of smoking on sperm vitality, DNA integrity, seminal oxidative stress, zinc in fertile men.

Objective: To assess the effect of smoking on sperm vitality, sperm DNA integrity, semen reactive oxygen species, and zinc levels in fertile men.

Methods: One-hundred sixty men were investigated. They were divided into 2 equal groups: healthy fertile nonsmokers and healthy fertile smokers.
