O 22: Reactive Oxygen Species and Epilepsy

Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...

the correlation between reactive oxygen species and leukocytes in normozoospermia and oligoasthenoteratozoospermia ejaculates

background and purpose: an important factor involved in infertility is reactive oxygen species (ros). ros can damage sperm dna, and involve lipid per-oxidation. ros elevation is under the influence of leukocyte activation. the objective of this study was to evaluate the level of ros as well as leukocyte, in normozoospermic (no) and ologoasthenoteratozoospermic (oat) ejaculates. materials and me...

I-3: Reactive Oxygen Species: A Dilemma for

Spermatozoa are very special cells and constantly exposed to the interphase between oxidative stress through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions of spermatozoa as being the only cells with such high polarization and exerting their functions outside the body, even in a differen...

Reactive oxygen species in mechanotransduction.

A RANDOMIZED CLINICAL TRIAL by the Acute Respiratory Distress Syndrome Network (1) demonstrated a 22% reduction in mortality in patients by reducing the tidal volume for mechanical ventilation from the conventional setting of 12 ml/kg to a lower setting of 6 ml/kg. This dramatic decrease in mortality has stimulated significant interest in the mechanisms of ventilatorinduced lung injury and the ...

Mitochondrial reactive oxygen species and calcium uptake regulate activation of phagocytic NADPH oxidase.

Production of superoxide (O(2)(·-)) by NADPH oxidases contributes to the development of hypertension and atherosclerosis. Factors responsible for activation of NADPH oxidases are not well understood; interestingly, cardiovascular disease is associated with both altered NADPH oxidase activity and age-associated mitochondrial dysfunction. We hypothesized that mitochondrial dysfunction may contrib...
