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.

Study suggests SARS-CoV-2 could affect aquatic wildlife

Researchers have found that oxidative stress and neurotoxicity biomarkers increased in tadpoles exposed to synthetic SARS-CoV-2 spike protein peptides.

UH researcher working to identify potential new therapeutic targets for kidney disease

Among the primary forms of kidney disease, focal segmental glomerulosclerosis (FSGS) is the most common and is marked by high circulating levels of the suPAR protein (soluble urokinase-type plasminogen activator receptor).

Study reveals cardiac protein as a new target for different types of heart disease

Like a failing fuel pump that causes a loss of engine power in a car, a diseased heart can take a serious toll on the body's performance. For some patients, tasks like walking up a flight of stairs or walking across a room eventually turn into exhausting endeavors.

Study: Dual use of cigarettes and e-cigarettes may not cut risk of cardiovascular disease

Cardiovascular disease is the leading cause of death associated with smoking cigarettes. But as use of e-cigarettes ("vaping") becomes more popular, including as a way to cut back on cigarettes, little is known about its effect on cardiovascular health.

Statins may protect the heart from damaging side-effects of early breast cancer treatment

New research from UHN's Peter Munk Cardiac Centre (PMCC) shows statins, commonly prescribed to lower cholesterol and reduce the risk of heart disease and stroke, may also protect the heart from damaging side-effects of early breast cancer treatment.

Biological imbalance found to be the link between gum and kidney disease

An imbalance of the body's oxygen producing free radicals and its antioxidant cells could be the reason why gum disease and chronic kidney disease affect each other, a new study led by the University of Birmingham has found.

New analysis finds no benefit in providing supplemental oxygen to mothers during childbirth

Babies who suffer oxygen deficiencies during birth are at risk of brain damage that can lead to developmental delays, cerebral palsy and even death.

Smoking traditional cigarettes along with e-cigarettes causes harmful health effects

Smoking traditional cigarettes in addition to using e-cigarettes results in harmful health effects similar to smoking cigarettes exclusively, according to new research published today in the American Heart Association's flagship journal Circulation.

Scientists develop an enhanced version of phototoxic protein

Scientists from Skoltech, the Institute of Bioorganic Chemistry of RAS, and the London Institute of Medical Sciences (LMS) have developed an enhanced version of SuperNova, a genetically encoded phototoxic synthesizer, that helps control intracellular processes by light exposure.

Scientists discover how a 'sociable' protein can hold clues about Alzheimer's origin

An international team of scientists led by the ESRF, the European Synchrotron, have found how the ECSIT protein dictates the behavior of proteins linked to the energy activity in mitochondria, which is largely affected in Alzheimer's disease.

Research sheds light on the underprediction riddle of biomass burning

Oxidized organic aerosol is a major component of ambient particulate matter, substantially impacting climate, human health, and ecosystems.

Research presents potential therapeutic strategy for reducing age-related diseases

Research findings by a KAIST team provide insight into the complex mechanism of cellular senescence and present a potential therapeutic strategy for reducing age-related diseases associated with the accumulation of senescent cells.

Mice study identifies action mechanism of a promising drug against Alzheimer's disease

A study conducted on mice published in the journal Geroscience has identified the action mechanism of a promising compound against Alzheimer's disease, developed by the team of Medical Chemistry and Pharmacology at the University of Barcelona.

Repair protein may prevent damage to healthy cells during cancer therapy

A key way radiation therapy and chemotherapy work is by making highly lethal double-strand breaks in the DNA of cancer cells.

Reductive stress promotes protein aggregation in neuroblastoma cells, impairs neurogenesis

Cells require a balance among oxidation-reduction reactions, or redox homeostasis. Loss of that balance to create oxidative stress is often associated with neurodegeneration. Less is known about how loss of that balance at the other end of the spectrum -- reductive stress, or RS -- may affect neurons.

Free radicals may be important for the brain to remain adaptable

Reactive oxygen molecules, also known as "free radicals", are generally considered harmful. However as it now turns out, they control cellular processes, which are important for the brain's ability to adapt - at least in mice.

Study shows beneficial effects of blackcurrants on post-meal glucose response

Blackcurrants have a beneficial effect on post-meal glucose response, and the required portion size is much smaller than previously thought, a new study from the University of Eastern Finland shows.

Cancer cells exhibit metabolic changes that make them vulnerable to ferroptosis

If there is a silver lining in cancer's chaotic biology, it's that the same traits that give cancer cells a growth advantage often present opportunities for sabotaging them.

Could the keto diet help prevent or mitigate severe COVID-19?

A new study published in the journal of Translational Medicine reports that the ketogenic diet (KD) may be useful in this area, with its track history of effectual reduction of fat mass, anti-inflammatory and immunomodulatory effects, and consequent improvement of cardiovascular health.

Healthy diet plays vital role in warding off COVID-19

A researcher at the School of Human Development and Health, Faculty of Medicine, University of Southampton, explored nutrition's role in boosting the immune system to combat COVID-19 infection.
