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: Any form of exercise may not be the most effective prognostic tool for heart failure patients

While exercise therapy for heart failure (HF) patients with low heart function has been shown to be an effective prognostic tool, the level and format of exercise that yields optimal effects is still unclear.

Study shows how mesenchymal stromal cells regulate factors driving inflammation in COPD patients

A new phase I clinical study shows, for the first time, how treatment with a type of stem cell called mesenchymal stromal cells is able to regulate important factors driving inflammation in patients with chronic obstructive pulmonary disease (COPD) for a period for time.

New study shows how quickly vaping can affect the cells of healthy younger nonsmokers

The risk that both tobacco and electronic cigarettes can pose to regular smokers' health has been well documented, but a new UCLA study illustrates just how quickly vaping can affect the cells of even healthy younger nonsmokers.

Research reveals a microRNA network as putative mediators of myocardial reductive stress

Last year, University of Alabama at Birmingham researchers reported that reductive stress -; an imbalance in the normal oxidation/reduction homeostasis -; caused pathological changes associated with heart failure in a mouse model.

Researchers develop the most comprehensive molecular map of lung squamous cell carcinoma

Lung cancer remains the leading cause of cancer-associated death in the United States and worldwide. Patients with a subtype called lung adenocarcinoma (LUAD) have benefited from the development of new targeted medicines, but the search for effective new therapies for another subtype called lung squamous cell carcinoma (LSCC) has largely come up short.

Key protein linked to both physical fitness in youth and diseases of old age

Researchers from Johns Hopkins Medicine say they have added to evidence that a protein called CaMKII improves strength, endurance, muscle health and fitness in young animals.

Latin American and Caribbean research contributions to tackle challenges posed by brain diseases

Every year there are nearly ten million new cases of dementia globally, of which Alzheimer's Disease (AD) is the most common form, accounting for around 60-70% of cases.

People with OSA have greater risk of sudden death and cardiovascular conditions

A study by Penn State College of Medicine researchers reveals that people living with obstructive sleep apnea (OSA), a condition that occurs when a person's airway becomes blocked while they are asleep, are twice as likely to experience sudden death compared to people living without OSA.

Component derived from turmeric essential oil exhibits neuroprotective effects

Researchers from Kumamoto University, Japan have found that a component derived from turmeric essential oil, aromatic turmerone (ar-turmerone), and its derivatives act directly on dopaminergic nerves to create a neuroprotective effect on tissue cultures of a Parkinson's disease model.

Urban environment with high levels of air pollution associated with childhood obesity risk

Children living in urban areas with high levels of air pollution, noise and traffic may be at higher risk of childhood obesity, according to a study by the Barcelona Institute for Global Health (ISGlobal)--a centre supported by the "la Caixa" Foundation--and the University Institute for Primary Care Research Jordi Gol (IDIAP Jordi Gol). The study was funded by the La Marató de TV3 Foundation.

Research reveals how mitochondria keep their reactive oxygen species production in check

Mitochondria, the powerhouse of the cell, convert sustenance into energy, fueling the cell's activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the other units in the cells.

An antioxidative stress regulator helps keep muscles from becoming weak in low gravity

Most kids dream of growing up to be astronauts; but the downside of spending extended amounts of time in low gravity is that astronauts' muscles tend to shrink and weaken through disuse. Now, researchers from Japan have identified a protein that affects how muscles respond to space flight.

Study unravels the link between chromosomal instability and cellular senescence

Chromosomal instability is a feature of solid tumours such as carcinoma. Likewise, cellular senescence is a process that is highly related to cellular ageing and its link to cancer is becoming increasingly clear. Scientists led by ICREA researcher Dr. Marco Milán at IRB Barcelona have revealed the link between chromosomal instability and cellular senescence.

Methylglyoxal detoxification deficits can be involved in the development of schizophrenia

Methylglyoxal (MG) is a highly reactive α-ketoaldehyde formed endogenously as a byproduct of the glycolytic pathway. MG accumulates under conditions of hyperglycemia, impaired glucose metabolism, or oxidative stress.

Salivary markers of oxidative stress during severe COVID-19

An interesting study from researchers at the University of Sharjah, Sharjah, United Arab Emirates, presents evidence that an elevated level of expression of oxidant molecules may be correlated with severe infection and lung injury.

Strength training for breathing muscles lowers blood pressure, improves vascular health

Working out just five minutes daily via a practice described as "strength training for your breathing muscles" lowers blood pressure and improves some measures of vascular health as well as, or even more than, aerobic exercise or medication, new CU Boulder research shows.

LSL60101 compound improves cognitive deficit in murine models with Alzheimer’s

The LSL60101 compound, a specific ligand of the I2-IR receptors in the brain, could shed light on the development of future strategies against Alzheimer's disease.

Differences in human and mouse brain cells have implications for research into neurological disorders

A UCLA-led study comparing brain cells known as astrocytes in humans and mice found that mouse astrocytes are more resilient to oxidative stress, a damaging imbalance that is a mechanism behind many neurological disorders.

SARS-CoV-2 causes ER-stress-activated unfolded protein response leading to cell death

A new study describes the varying ways in which the virus co-opts the machinery of the host cell following infection to evade or modulate the host immune response, alter the pattern of translation of viral proteins, and the release of new viral particles.
