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...
متن کاملReactive Oxygen Species and Antioxidant in Seminal Plasma and Their Impact on Male Fertility
Spermatozoa generate reactive oxygen species (ROS) in physiological amounts which play a role in sperm functions during sperm capacitation acrosome reaction (AR) and oocyte fusion. In addition damaged sperm are likely to be the source of ROS. The most important ROS produced by human sperm are hydrogen peroxide superoxide anion and hydroxyl radicals. Besides human seminal plasma and sperm posses...
متن کاملO 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 ...
متن کاملO-13: Evaluation of Leptin Concentration in Seminal Plasma and Its Correlation with Reactive Oxygen Species, Lipid Peroxidation and Pronuclear Formation in Candidates for ICSI Treatment
Background Leptin, as a key hormone in energy homeostasis, plays an important role in reproduction and male fertility. However, its negative or positive effect on sperm quality and assisted reproduction technique is still controversial. The aim of this study was the comparison of seminal leptin concentration in selected couples with male and female factor for intracytoplasmic microinjection (IC...
متن کاملReactive Oxygen Species, Apoptosis, and Mitochondrial Dysfunction in Hearing Loss
Reactive oxygen species (ROS) production is involved in several apoptotic and necrotic cell death pathways in auditory tissues. These pathways are the major causes of most types of sensorineural hearing loss, including age-related hearing loss, hereditary hearing loss, ototoxic drug-induced hearing loss, and noise-induced hearing loss. ROS production can be triggered by dysfunctional mitochondr...
