BACKGROUND Infertility is defined as the inability to achieve the pregnancy within a year of unprotected intercourse. Infertility is a complex issue and different factors such as stress oxidative can be involved in this problem. So, any attempt to neutralize oxidative stress would be helpful in the treatment of infertility. Melatonin is a known scavenger of free radicals. OBJECTIVE The aim of...

Despite treatment of patients with metastatic colorectal cancer (mCRC) with bevacizumab plus chemotherapy, response rates are modest and there are no biomarkers available that will predict response. The aim of this study was to assess if markers associated with three interconnected cancer-associated biological processes, specifically angiogenesis, inflammation and oxidative damage, could strati...

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease whose pathogenic mechanisms remain to be elucidated. The oxidative stress and antioxidants play an important role in the disease process of RA. The study of oxidants and antioxidants biomarkers in RA patients could improve our understanding of disease pathogenesis; likely determining the oxidative stress levels in these patients co...

Objectives: The present study is aimed at investigating the involvement of oxidative stress in ischemic heart disease (IHD) of patients in tertiary care hospital in Kolkata. Methods: Serum parameters of myocardial injury, oxidative stress biomarkers and antioxidant enzymes were measured. These data were supported by the data of electrocardiography and echocardiography. Results: The current stud...

Saliva is easily obtainable for medical research and requires little effort or training for collection. Because saliva contains a variety of biological compounds, including vitamin C, malondialdehyde, amylase, and proteomes, it has been successfully used as a biospecimen for the reflection of health status. A popular topic of discussion in medical research is the potential association between o...

BACKGROUND The objective of this study was to measure malondialdehyde (MDA) and isoprostane which has been used as an index of lipid injury, 8-hydroxy-2'-deoxyguanosine (8-OHdG), which has been used as an index of DNA damage, and dialkyl-phosphate (DAP), which has been used to quantify pesticide exposure, and to investigate the relationship between pesticide exposure and oxidative stress. MET...

The aim of this study is whether oxidative stress markers, homocysteine (Hcy), cardiac troponin I (cTnI) and the activity of adenosine deaminase (ADA) alter following administration of different doses of sertraline. Sixty male Wistar rats were assigned into four groups. Sertraline at doses of 20, 40 and 80 mg / kg / day) were administered to three groups through gastric gavage for 90 days. The ...

Previous studies have investigated the associations between exposure to ambient air pollution and biomarkers of physiological pathways, yet little has been done on the comparison across biomarkers of different pathways to establish the temporal pattern of biological response. In the current study, we aim to compare the relative temporal patterns in responses of candidate pathways to different p...
