Endothelin-1 in paraventricular nucleus modulates cardiac sympathetic afferent reflex and sympathetic activity in rats. [PDF]
Cardiac sympathetic afferent reflex (CSAR) is a positive-feedback, sympathoexcitatory reflex. Paraventricular nucleus (PVN) is an important component of the central neurocircuitry of the CSAR. The present study is designed to determine whether endothelin-

Oxidative stress and disruption of the antioxidant defense system as triggers of diseases
Oxidative stress is a state when the content of free radicals in a living organism is excessive. Molecules of free radical nature start a chain reaction that disrupts the integrity of cells, leading to their damage or death.

The Regulation of Trace Metal Elements in Cancer Ferroptosis
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Reactions of Phenolic Antioxidants with Electrogenerated Superoxide Anion Radical and Their Analytical Application [PDF]
Parameters of oxygen electroreduction on glassy carbon electrode modified with multi-walled carbon nanotubes were found. Increase in the oxygen reduction currents and system reversibility was observed compared to unmodified electrode, which allows to use
