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.

Pollutant from forest and crop fires induces genetic damage in human lung cells

When exposed in a laboratory to pollution levels comparable to those found in the atmosphere of the Amazon region during the forest and crop burning season, human lung cells suffer severe DNA damage and stop dividing. After 72 hours of exposure, over 30% of the cultured cells are dead.

Stem cell researchers make advance toward long-lasting blood vessel repair

Stem cell researchers at Emory University School of Medicine have made an advance toward having a long-lasting "repair caulk" for blood vessels. The research could form the basis of a treatment for peripheral artery disease, derived from a patient's own cells. Their results were recently published in the journal Circulation.

E-cigarettes may activate distinctive and potentially damaging immune responses, study reveals

A new study, published in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine, suggests that e-cigarettes may stimulate distinct immune responses along with the same responses that cigarettes stimulate resulting in lung disease.

Findings suggest e-cigarettes may be just as bad as traditional cigarettes

E-cigarettes appear to trigger unique immune responses as well as the same ones that cigarettes trigger that can lead to lung disease, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Migraine attacks may actively protect and repair the brain from oxidative stress

A new perspective article highlights a compelling theory about migraine attacks: that they are an integrated mechanism by which the brain protects and repairs itself. Recent insightful findings and potential ways to use them to help migraine sufferers are published in Headache.

Study identifies new biomarker for depression in diabetes

A study published in the current issue of Psychotherapy and Psychosomatic has identified a biomarker for depression in diabetes. Findings of epidemiological studies have shown an overall 2-fold increased prevalence of depression in patients with type 2 diabetes compared with the general population worldwide.

Research will explore biological mechanisms triggered by air pollution exposure during pregnancy

New research will seek to understand the biological mechanisms that are triggered by exposure to air pollution during pregnancy and lead to lower birth weight in newborns, placing them at greater risk for chronic conditions such as coronary heart disease and hypertension later in life.

New research uncovers how blood cancer 'steals' parts of bone marrow cells to thrive

New research published today uncovers how the blood cancer 'steals' parts of surrounding healthy bone marrow cells to thrive, in work that could help form new approaches to cancer treatment in the future.

Researchers look for ways to prevent chemotherapy-induced cognitive impairment

Of the 14 million cancer survivors in the United States, a significant number experience a serious side effect called chemotherapy-induced cognitive impairment (CICI). While easily recognized, little is known about the etiology of this condition, also known informally as "chemo brain."

Impairing critical partnership between brain cells can lead to Alzheimer's disease

Researchers have discovered that impairing a critical partnership between brain cells can lead to neurodegeneration. The study published in Cell Metabolism reports a mechanism by which two types of brain cells, neurons and glia, normally support each other's functions.

Reducing antioxidant levels in the colon may have positive effect on GI inflammation

A new study finds that lowering the levels of an antioxidant in the colon has an unexpectedly positive effect on gastrointestinal (GI) inflammation. The paper is published ahead of print in the American Journal of Physiology-;Gastrointestinal and Liver Physiology.

Metabolism can impact host's susceptibility to develop malaria

Researchers from Instituto de Medicina Molecular Lisboa have found that the host's susceptibility to develop malaria depends on his or her metabolic state, which can be easily manipulated through external stimuli such as dietary patterns.

Researchers discover mechanism of drug resistance for ovarian and breast cancer cells

Researchers from the People's Friendship University of Russia have studied the mechanism of drug resistance for ovarian and breast cancer cells.

Increased adrenaline levels in non-smokers’ hearts seen with the use of one e-cigarette with nicotine

A new study conducted at the University of California, Los Angeles, found that if non-smokers use one electronic cigarette that contains nicotine, they experience a rise in adrenaline levels in their heart; however, if the e-cigarette is nicotine-free, there was no increase in the levels of adrenaline.

UTMB scientists gain new insights into factors that lead to preterm birth

A group of scientists led by Ramkumar Menon at The University of Texas Medical Branch at Galveston has gained new insights into what factors lead to preterm birth. This study is currently available in The American Journal of Pathology.

New man-made antioxidant could help improve success rates of cell-based therapies

Cell therapies being developed to treat a range of conditions could be improved by a chemical compound that aids their survival, research suggests.

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.
