Abstract Background: Recent studies have suggested that oxidative stress (OS) may have a contribution in the pathogenesis of endometriosis. However, the results of previous studies regarding OS in endometriosis are controversial. The objective of this study was to compare the serum levels of OS markers in endometriosis versus the control group. Methods: This case-control study was carried out...

Graves' disease is a most common cause of hyperthyroidism. It is an autoimmune disease, and autoimmune process induces an inflammatory reaction, and reactive oxygen species (ROSs) are among its products. When balance between oxidants and antioxidants is disturbed, in favour of the oxidants it is termed "oxidative stress" (OS). Increased OS characterizes Graves' disease. It seems that the level ...

background: organophosphorus (op) compounds are used to control pests, however they can reach the food chain and enter the human body causing serious health problems by means of acetylcholinesterase (ache) inhibition and oxidative stress (os). among the ops, chlorpyrifos (chp), malathion (mal), and diazinon (dia) are commonly used for commercial extermination purposes, in addition to veterinary...

The commonly-accepted “oxidized LDL hypothesis of atherogenesis” is based on a large number of indirect evidence that shows that oxidatively-modified LDL plays a role in atherogenesis. Yet, the exact role is not clear. Some researchers think that oxidatively modified biomolecules initiate atherogenesis; others believe that they “only” promote this multifactorial process. Regardless of the exact...

Background Metabolic syndrome (MetS) comprises pathological conditions that include insulin resistance, arterial hypertension, visceral adiposity and dyslipidemia, which favors the development of cardiovascular diseases and type 2 diabetes. Advanced oxidation protein products (AOPPs) have been reported as the most appropriate parameter for determination of oxidative stress (OS) in MetS patients...

Accumulating evidence has indicated that oxidative stress (OS) is associated with the development of hepatocellular carcinoma (HCC). However, the mechanisms remain largely unknown. Normally, OS occurs when the body receives any danger signal-from either an internal or external source-and further induces DNA oxidative damage and abnormal protein expression, placing the body into a state of vulne...

background: the aim of this study was to determine oxidative stress (os) parameters after testicular torsion/detorsion in adult rats. materials and methods: in this experimental study, male adult wistar rats were divided into four groups, each consisting of seven animals: group i-one hour right testicular torsion with subsequent orchiectomy, group ii-one hour right testicular torsion followed b...

results a significant higher serum pab value was observed in shift working and daytime nurses (152.28 ± 43.64 hk) in comparison to the control group (63.64 ± 34.41 hk index), p value = 0.001. in day time nurses, also serum pab between male (119.09 ± 47.14 hk) and female (162.53 ± 37.02 hk) in nursing workers was significant, p value = 0.005. in the night shift working nurses, there was also a s...

Objective Oxidative stress (OS) has been associated with numerous adverse pregnancy outcomes and fetal disturbances. Due to overproduction of reactive oxygen (ROS) and reactive nitrogen species (RNS) as well as inadequate induce of antioxidant protection newborns are particularly susceptible to oxidative injury. Furthermore, it has been shown that oxidative stress in adipose tissue may also imp...

Oxidative stress (OS) has been implicated as one of the major underlying mechanisms behind many acute and chronic diseases. However, the measurement of free radicals or their end products is complicated. Isoprostanes, derived from the non-enzymatic peroxidation of arachidonic acid are now considered to be reliable biomarkers of oxidant stress in the human body. Isoprostanes are involved in many...
