Oxidative Stress News and Research

RSS

Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Asian dust exposure associated with onset of myocardial infarction

A recent environmental epidemiological study by Japanese researchers has shown that Asian sand particles blown to Japan from desert areas of the Asian continent are associated with the onset of myocardial infarction.

STING signaling pathway induces apoptosis in T cells

EPFL scientists show that the STING signaling pathway, which helps coordinate the innate immune system, causes cell death in T cells of the adaptive immune system. This “killing” effect includes cancerous T cells, and has implications for treating T cell-derived cancers.

Compounds found in cocoa could help combat diabetes, say BYU researchers

What if eating chocolate helped prevent and treat diabetes? It's crazy enough to laugh off. But here's the thing: BYU researchers have discovered certain compounds found in cocoa can actually help your body release more insulin and respond to increased blood glucose better. Insulin is the hormone that manages glucose, the blood sugar that reaches unhealthy levels in diabetes.

Study finds ethylene release in exhaled breath as early biomarker of bacterial infection

Although ethylene (or ethene) is best known as a plant hormone, humans also produce it as consequence of oxidative stress, caused for example by the UV radiation from the sun.

Study: Liver inflammation increases cholesterol levels in people with diabetes

Inflammatory processes in the liver lead to elevated cholesterol levels in people with diabetes, thus promoting subsequent vascular diseases. This is the result of a study by scientists of Helmholtz Zentrum München, Technische Universität München and the Collaborative Research Center SFB 1118 at Heidelberg University Hospital.

UBC researchers develop method to quickly and sensitively assess malaria progression

Left untreated, malaria can progress from being mild to severe -- and potentially fatal -- in 24 hours. So researchers at the University of British Columbia developed a method to quickly and sensitively assess the progression of the mosquito-borne infectious disease, which remains a leading killer in low-income countries.

DNA-sensing mechanism of innate immune system controls cellular senescence

Cells in the body or in cultures eventually stop replicating. This phenomenon is called "senescence" and is triggered by shortening of telomeres, oxidative stress or genetic damage to the cells, either acute or simply due to the cell growing "old".

First in-car study of rush hour pollution finds alarming results

The first in-car measurements of exposure to pollutants that cause oxidative stress during rush hour commutes has turned up potentially alarming results.

Promoting innate detoxification mechanisms could be efficient strategy to reduce cellular oxidative stress

Promoting innate detoxification mechanisms in the body and discovering which supplements increase the efficacy of those biochemical pathways could be an efficient strategy to reduce the cellular oxidative stress and protect our health, according to an article published in the journal Food Chemistry, by the researchers Rafael Franco, from the Institute of Biomedicine of the University of Barcelona, and Eva Martínez Pinilla, from the Institute of Neurosciences of Asturias and the University of Oviedo.
