Oxidative stress is considered to be involved in the pathophysiology of all cancers. In order
to evaluate the total oxidant/antioxidant status in patients with thyroid cancer and to …

Data on the antioxidant levels enzyme in patients with hyperthyroidism are limited and
conflicting. Therefore, the objective of this study was to evaluate the oxidative status using …

Background Reactive oxygen species (ROS) are balanced through enzymatic mechanisms
and exogenous antioxidants; imbalance results in oxidative stress (OxS). It is known that …

Background Oxidative stress and trace elements have been implicated in the development
of breast cancer. However, how they contribute to the pathogenesis of the disease and the …

Oxidative stress (OS) is a state of excessive free radicals and reactive metabolites among
which the most important class is reactive oxygen species (ROS)–radicals derived from …

Simple Summary Several pieces of evidence indicate an impact of oxidative stress (OS) in
the pathogenesis and progression of thyroid cancer. The aim of the study was to investigate …

Introduction: Thyroid epithelial cells produce moderate amounts of reactive oxygen species
that are physiologically required for thyroid hormone synthesis. Nevertheless, when they are …

The aim of this study was to evaluate and compare the oxidative profiles of three thyroid
disorders: Graves' disease (GD), Hashimoto thyroiditis (HT), and papillary thyroid cancer …

Oxidative stress is involved in a variety of diseases. Prospective studies investigating the
relationship between oxidative stress biomarkers and the status and development of …

The aim of this study was to determine levels of serum 8-hydroxy-2′-deoxyguanosine (8-
OHdG) as an indicator of oxidant-induced DNA damage and oxidant status in patients with …
