Bioimaging Probes for Reactive Oxygen Species and Reactive Nitrogen Species

open access: yesJournal of Clinical Biochemistry and Nutrition, 2009
Reactive oxygen species (ROS) play key roles in many pathogenic processes, including carcinogenesis, inflammation, ischemia-reperfusion injury and signal transduction. Also, reactive nitrogen species (RNS) cause various biological events such as neurodegenerative disorders.

Reactive nitrogen and oxygen species in anticoagulated blood of healthy sheep

open access: yes, 2013
Background : Little or no study has been done to compare the indices of ‘nitrosative’ and ‘oxidative’ stresses, especially in terms of correlation and the possible differential effects of the chelating agents.

Evaluation of melatonin levels in saliva in periodontal health and disease: A clinico-biochemical study

open access: yesJournal of International Clinical Dental Research Organization, 2010
Background: Melatonin, a secretory product of the vertebrate pineal gland, activates several elements of the immune system that reduce tissue destruction during the inflammatory response, either directly by scavenging free radical, reactive oxygen ...

Periodontal disease etiology and role of oxidative stress

open access: yesMagazin of Al-Kufa University for Biology, 2023
The term "periodontal disease" is used to describe an array of inflammatory conditions that can affect the periodontium. In response to the challenge given by the bacteria, the gingival and periodontal tissues undergo a complicated chain of events ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Reactive oxygen and nitrogen species in pulmonary hypertension [PDF]

open access: yesFree Radical Biology and Medicine, 2012
Pulmonary vascular disease can be defined as either a disease affecting the pulmonary capillaries and pulmonary arterioles, termed pulmonary arterial hypertension, or a disease affecting the left ventricle, called pulmonary venous hypertension. Pulmonary arterial hypertension (PAH) is a disorder of the pulmonary circulation characterized by endothelial

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Reactive Nitrogen in the Tropical Troposphere [PDF]

open access: yes, 2013
The aim of this project was to calibrate a thermal-decomposition chemiluminescence (TD-Chem) instrument, capable of measuring the composition of the reactive nitrogen pool at the Cape Verde Atmospheric Observatory (CVAO) in the remote tropical ...

Antioxidants and skeletal muscle performance: ’Common knowledge’ vs. experimental evidence.

open access: yesFrontiers in Physiology, 2012
Antioxidants are assumed to provide numerous benefits, including better health, a reduced rate of aging, and improved exercise performance. Specifically, antioxidants are commonly ‘prescribed’ by the media, supplement industry, and ‘fitness experts’ for
