In recent years, incremental rate of electrical demands made many challenges for policy makers of power systems. Besides, due to economic crisis and environmental concerns about the air pollution, the new investments in thermal power generation units have experienced a noticeable reduction. For this reason, the power system operators should propose novel approaches to make a balance between inc...

BACKGROUND AND PURPOSE Brain tumors affecting language-relevant areas may influence language lateralization. The purpose of this study was to systematically investigate language lateralization in brain tumor patients using clinical language fMRI, comparing the results with a group of healthy volunteers. MATERIALS AND METHODS Fifty-seven strictly right-handed patients with left-hemispheric-spa...

AIMS The effect of ethanol on glucose synthesis in kidney-cortex tubules of control and diabetic rabbits has been investigated. METHODS Both freshly isolated and grown in primary cultures, kidney-cortex tubules were incubated with alanine or aspartate plus lactate or glycerol plus octanoate in the absence and presence of 100 mmol/l ethanol. RESULTS In freshly isolated renal tubules incubate...

The higher risk of venous thromboembolism with 3rd and 4th- generations combined oral contraceptives compared to 2nd generation triggered a media crisis in France. Exposure to 3rd or 4th-generation combined oral contraceptives led to an annual excess of around 100 premature deaths in Europe. In the absence of any demonstrated additional benefit of these combined oral contraceptives, measures we...

This review examines the effect of mitochondrial generation of reactive oxygen species (ROS) and aging on human spermatozoa and seminal antioxidants. We discuss the effect of continuous ROS production on biomarkers of aging, such as germ cell telomeres and telomerase, lipofuscin, and amyloid. These markers may be responsible for telomere shortening and subsequent decrease in sperm count, declin...
