Cell Membranes and Free Radical Research is a print and online journal that publishes original research articles, reviews and short reviews on the molecular basis of biophysical, physiological and pharmacological processes that regulate cellular function, and the control or alteration of these processes by the action of receptors, neurotransmitters, second messengers, cation, anions, drugs or disease.Areas of particular interest are four topics. They areA- Ion Channels (Na+ - K+ Channels, Cl – channels, Ca+2 channels, ADP-Ribose and metabolism of NAD+, Patch-clamp applications), B- Oxidative Stress (Antioxidant vitamins, Antioxidant enzymes, Metabolism of Nitric oxide, Oxidative stress, The biophysics of the radicals which springed up from oxygen ), C- Interaction Between Oxidative Stress and Ion Channels (Effects of The Oxidative Stress On The Activation of The Voltage Sensitive Cation Channels, Effect of ADP-Ribose and NAD On Activation of The Cation Channels Which Are Sensitive to Voltage, Effect of The Oxidative Stress On Activation of the TRP Transient Potential Channels ), D- Gene and oxidative stress (Gene abnormalities. Interaction between gene and free radicals. Gene anomalies and iron. Role of radiation and cancer on gene polymorphism).
