Reactive oxygen species (ROS) are involved in physiological and pathological processes either as trigger agents or, more frequent, accompanying and/or aggravating the primary lesions. The authors observed the changes of some oxidative stress markers (lipo... see more

Pulmonary arterial hypertension (PAH) is a progressive disease of the lung vasculature that involves the loss of endothelial function together with inappropriate smooth muscle cell growth, inflammation, and fibrosis. These changes underlie a progressive r... see more

Introduction and aim.Reactive oxygen species and increased oxidative stress cause a series of disorders in the metabolism of the cell. Initiate adverse changes to the structure of DNA, lipids and proteins. The purpose of this article is to introduce the c... see more

Introduction. Activation of lipid peroxidation is one of the trigger mechanisms of periodontium injury, which is primary caused by cellular damage. Reactive oxygen and nitrogen species (RONS) are able to cause damage to a cell as well as final products of... see more

Development of the most of pathological conditions occurs by free radical mechanism which is characterized by increased free radical production at the cellular level, especially reactive oxygen and nitrogen species (ROS/RNS). The main producers of reactiv... see more

Fifteen years ago, in 2001, the concept of “Reactive Sulfur Species” or RSS was advocated as a working hypothesis. Since then various organic as well as inorganic RSS have attracted considerable interest and stimulated many new and often unexpected avenue... see more

Chronic wounds and ulcers are major public health threats. Being a substantial burden for patients and health care systems alike, better understanding of wound pathophysiology and new avenues in the therapy of chronic wounds are urgently needed. Cold phys... see more

Reactive oxygen and nitrogen species (RONS) are important cellular regulators of key physiological processes in skeletal muscle. In this review, we explain how RONS regulate muscle contraction and signaling, and why they are important for membrane remodel... see more
