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.

Green space linked to reduced risk of heart disease and stroke

Researchers have shown that people who live in neighborhoods with denser greens paces may be at a lower risk of developing heart disease and stroke.

IU scientists find toxic flame retardants in children's car seats

In a new study, Indiana University scientists found toxic flame retardants in newly manufactured children's car seats, sparking concerns about children's health. Of the 18 children's car seats tested, 15 contained new or traditional hazardous flame retardant chemicals.

Study uncovers new chemical reaction key to cataract formation

Researchers working to understand the biochemistry of cataract formation have made a surprising finding: A protein that was long believed to be inert actually has an important chemical function that protects the lens of the eye from cataract formation.

Scientists discover important hallmark of aging in neuronal cells

MIT researchers have discovered that free radicals cause a build-up of short RNA snippets which could contribute to neuronal ageing and cognitive decline.

Scientists discover new inhibitor that decreases lung inflammation

Scientists from the University of Sheffield have discovered a new inhibitor which decreases lung inflammation and could hold the key to treating Acute Respiratory Distress Syndrome - a life-threatening disease which affects thousands of people in the UK.

Study could provide novel treatment strategy for potentially blinding problem

An enzyme known to help our liver get rid of ammonia also appears to be good at protecting our retina, scientists report.

UCV researchers discover the influence of exosomes on age-related macular degeneration

Researchers of the Neurobiology and Neurophysiology team of the Medicine Faculty at Valencia Catholic University, headed by Jorge Bacia, have discovered that exosomes - microscopic extracellular vesicles that are released by all cells - from the retinal pigment epithelium lead to cases of neovascularization, a finding which could be closely related to similar processes in age-related macular degeneration.

Zinc can protect against oxidative stress when taken along with coffee, tea, and chocolate

Ageing and a low life expectancy are caused, at least partly, by oxidative stress. A team of researchers led by Prof. Dr. Ivana Ivanovi-Burmazovi from the Chair of Bioinorganic Chemistry at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), together with researchers from the USA, have discovered that zinc can activate an organic molecule, helping to protect against oxidative stress.

Genetic defect linked to ALS causes sugar-starved cells to overproduce lipids

A genetic defect tied to a variety of neurodegenerative diseases and mental illnesses changes how cells starved of sugar metabolize fatty compounds known as lipids, a new study led by researchers from the Johns Hopkins Bloomberg School of Public Health shows.

Common diabetes medication may protect against age-related macular degeneration

Researchers from Taiwan have shown that people with type 2 diabetes who took a common diabetes medication, metformin, had a significantly lower rate of age-related macular degeneration.

Getting right level of leptin may help protect cardiovascular health

Like that famous bowl of porridge, when leptin levels are "just right" they help protect our cardiovascular health, scientists say.

Study examines factors associated with fasting hyperglucagonemia in type 2 diabetes

A new study examined the relationship between fasting hyperglucagonemia -- which can negatively affect glucose metabolism in patients with type 2 diabetes -- and several biochemical and glycemic factors in subjects with T2D or in a nondiabetic control group.

Newly discovered compound shows potential for treating Parkinson's disease

A joint research group centered around Professor Hideyuki Okano and Associate Professor Jun Kohyama, Department of Physiology of the Keio University School of Medicine, together with a research group of Eisai Co., Ltd. has identified a compound that has the potential to be a treatment for Parkinson's disease by using dopaminergic neurons differentiated from induced pluripotent stem (iPS) cells from patients with familial Parkinson's disease.

Researchers develop fibrin-targeting immunotherapy to protect against neurodegeneration

Normally, the blood protein fibrin does not enter the brain. But in several neurological disorders, the blood-brain barrier--which keeps large molecules in the blood from entering the brain--becomes abnormally permeable, allowing fibrin to leak into the brain and trigger inflammation.

Exposure to magnetite particles is unlikely to contribute to Alzheimer’s disease

A 2016 study showed that exposure to urban pollution involving magnetite particles played a role in the development of Alzheimer's disease.

Flavoring, additive ingredients in e-cigarettes may increase inflammation and impair lung function

Flavoring and additive ingredients in e-cigarettes may increase inflammation and impair lung function, according to new research.

Brown researchers uncover new clues about ALS progression

Brown University researchers have uncovered new clues about the progression of Amyotrophic Lateral Sclerosis (ALS), a surprisingly common disease that causes the death of motor neurons that control voluntary muscles such as those involved in walking, talking, chewing or breathing.

Two related enzymes have opposing roles in heart failure

Two related enzymes have opposing roles in mouse heart muscle cells exposed to pressure overload, according to a recent study published in the Proceedings of the National Academy of Sciences, USA.

Study: Chemotherapy drugs may promote muscle mitochondrial dysfunction

Chemotherapy drugs to treat breast cancer may promote muscle mitochondrial dysfunction, according to new research. Dysfunctional mitochondria, the energy centers of the cells, may contribute to fatigue and weakness that some people with breast cancer experience through the course of disease treatment.
