Is sunlight good for our heart? [PDF]
, 2010 Humans evolved being exposed for about half of the day to the light of the sun. Nowadays, exposure to sunlight is actively discouraged for fear of skin cancer, and contemporary lifestyles are associated with long hours spent under artificial light ...

Scientifica, Volume 2026, Issue 1, 2026.Smoking is a main contributor to lung pathogenesis, inflammation, oxidative stress and structural changes. This study aimed to investigate the impact of cigarette smoke on lung tissue and to explore the potential benefit of ginger extracts in rats. Four groups of male rats were employed to achieve this goal.

Impact of high drinking water nitrate levels on the endogenous formation of apparent N-nitroso compounds in combination with meat intake in healthy volunteers [PDF]
, 2019 BACKGROUND: Nitrate is converted to nitrite in the human body and subsequently can react with amines and amides in the gastrointestinal tract to form N-nitroso compounds (NOCs), which are known to be carcinogenic in animals.

Thiyl radicals are co-products of dinitrosyl iron complex (DNIC) formation. [PDF]
, 2019 Thiyl radicals are detected by EPR as co-products of dinitrosyl iron complex (DNIC) formation. In demonstrating that DNIC formation generates RS˙ in a NO rich environment, these results provide a novel route for S-nitroso thiol ...

A Unifying Mechanism for Mitochondrial Superoxide Production during Ischemia-Reperfusion Injury. [PDF]
, 2016 Ischemia-reperfusion (IR) injury occurs when blood supply to an organ is disrupted--ischemia--and then restored--reperfusion--leading to a burst of reactive oxygen species (ROS) from mitochondria. It has been tacitly assumed that ROS production during IR

Observations, in vitro, on N-nitrosation by intracellular extracts of some microorganisms isolated from palm wine [PDF]
, 1981 Soluble fractions of sonicates derived from cell suspensions of some bacteria and yeasts, which contaminate palm sap, enhanced nitrosamine formation when each fraction was incubated, under sterile conditions, at a pH of 7.0 ± 0.2, with either ...

Blocked dihydropteridines as nitric oxide synthase activators [PDF]
, 2010 It has been shown that 6-acetyl-7,7-dimethyl-5,6,7,8-tetrahydropteridin-4(3H)-one can act as a competent cofactor for the production of nitric oxide by neuronal nitric oxide synthase (nNOS).

Carbon and nitrogen isotopic ratios of urine and faeces as novel nutritional biomarkers of meat and fish intake [PDF]
, 2012 Purpose Meat and fish consumption are associated with changes in the risk of chronic diseases. Intake is mainly assessed using self-reporting, as no true quantitative nutritional biomarker is available.
