Spaceflights cause cellular-level damage and may lead to long-term vision problems

Those who travel to space are rewarded with a beautiful sight - planet Earth. But the effects of space travel on the human sense of sight aren't so beautiful. More than 30 percent of astronauts who returned from two-week space shuttle missions and 60 percent who spent six months aboard the International Space Station were diagnosed with eye problems. Two recent investigations examined mechanisms that may explain eye changes in spaceflight, help find ways to minimize this health risk to astronauts and eventually prevent and treat eye diseases on Earth.

New family of drugs may help combat childhood tumor

St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project study identifies drugs that enhance oxidative stress as possible weapon against most common pediatric soft tissue tumor

Drugs that enhance oxidative stress kill rhabdomyosarcoma tumor cells

Drugs that enhance a process called oxidative stress were found to kill rhabdomyosarcoma tumor cells growing in the laboratory and possibly bolstered the effectiveness of chemotherapy against this aggressive tumor of muscle and other soft tissue. The findings are the latest from the St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project and appear in the December 9 edition of the scientific journal Cancer Cell.

Tel Aviv University says caffeine and alcohol can change part of DNA linked to aging, cancer

Coffee and beer are polar opposites in the beverage world. Coffee picks you up, and beer winds you down.

Baicalin inhibits colistin sulfate-induced apoptosis of PC12 cells

Baicalin, a type of flavonoid extracted from the dried root of Scutellaria baicalensis georgi, has been shown to effectively inhibit cell apoptosis. Colistin sulfate, a cyclic cationic polypeptide antibiotic, has been shown to have renal and neurological side effects.

BIDMC study shows carbon monoxide may have a role to play in treating cancer

In recent years, research has suggested that carbon monoxide, the highly toxic gas emitted from auto exhausts and faulty heating systems, can be used to treat certain inflammatory medical conditions. Now a study led by a research team at Beth Israel Deaconess Medical Center (BIDMC) shows for the first time that carbon monoxide may also have a role to play in treating cancer.

Researchers analyze protective effects of mild hypothermia on CNS injuries

There are few data on the effectiveness and mechanism underlying mild hypothermia in the treatment of central nervous system injuries. Therefore, there is a need to investigate the potentially beneficial effects of mild hypothermia on central nervous system injuries.

MitoQ Targeted Antioxidant Dietary Supplement now available

MitoQ Limited is excited to announce the release of their newest offering, MitoQ Targeted Antioxidant Dietary Supplement. Published studies show that the supplement, which delivers the well known antioxidant CoQ to the mitochondria (our cellular power source) better than ever before, helps repair mitochondrial dysfunction, significantly reduces oxidative damage to cells and by association supports heart, liver and brain health while assisting in the increase of energy, libido and healthy aging.

ATN-224 inhibitor reduces tumor sizes in mouse model of lung adenocarcinoma

Many cancers have adapted to cope with high levels of immune system-produced free radicals, also referred to as reactive oxygen species, by overproducing antioxidant proteins. One of these proteins, superoxide dismutase 1, is overproduced in lung adenocarcinomas and has been implicated as a target for chemotherapy.

Study: Diet low in vitamin D can cause free radical damage in brain

A new study led by University of Kentucky researchers suggests that a diet low in vitamin D causes damage to the brain.

Mutation in alpha-synuclein gene causes increased vulnerability to pesticides, leading to Parkinson's

A team of researchers has brought new clarity to the picture of how gene-environmental interactions can kill nerve cells that make dopamine. Dopamine is the neurotransmitter that sends messages to the part of the brain that controls movement and coordination.

Study investigates connections between sleep problems and neurodegenerative conditions

A new discovery may help explain the surprisingly strong connections between sleep problems and neurodegenerative conditions such as Alzheimer's disease.

Researchers identify new mechanism that causes neurodegeneration

As we age, our body rhythms lose time before they finally stop. Breaking the body clock by genetically disrupting a core clock gene, Bmal1, in mice has long been known to accelerate aging , causing arthritis, hair loss, cataracts, and premature death.

UCP1 protein helps fight against obesity

The uncoupling Protein 1 (UCP1) is found exclusively in brown adipose tissue. Until some years ago it was thought that only babies and hibernating animals had brown adipose tissue, but since then it also has been found in adults, so UCP1 could be useful in the fight against obesity.

Vitamin C can improve skeletal muscle fatigue in COPD patients

Chronic obstructive pulmonary disease—a health problem in which the lungs lose their inherent springiness, making it progressively harder to breathe—can have a dramatic effect on the ability to exercise and even perform simple activities of daily life because of the disease's fallout effects on skeletal muscles.

Study reveals that glial cells are integral to brain function

New research by scientists at UC San Francisco shows that one of the brain's fundamental self-protection mechanisms depends on coordinated, finely calibrated teamwork among neurons and non-neural cells knows as glial cells, which until fairly recently were thought to be mere support cells for neurons.

Common catalyst cerium oxide opens door to nanochemistry for medicine

Scientists at Rice University are enhancing the natural antioxidant properties of an element found in a car's catalytic converter to make it useful for medical applications.

Deficiency of antioxidant response protein prevents hypertrophic cardiomyopathy

University of Utah researchers have found that deficiency of an antioxidant response protein called nuclear erythroid-2 like factor-2 (Nrf2) delays or prevents hypertrophic cardiomyopathy, a type of a heart failure in which the heart muscle grows abnormally thick.

Researchers discover how Fra-1 protein protects the liver from drug-induced liver damage

Drug abuse and alcohol are some of the most frequent causes of liver damage, particularly in developed countries. Such kind of liver damage can cause irreversible liver failure and even cancer. Researchers from the Spanish National Cancer Research Centre have discovered an important new protective role of the Fra-1 protein, which neutralizes the damage caused by agents, such as the analgesic drug acetaminophen (Paracetamol).

Bioactive compounds in carrot can be used as antiviral for treatment against flu

Researchers from the FEMSA Center of Biotechnology at Technologic of Monterrey (ITESM) designed a technology that uses grated carrot to obtain phenolic compounds that have a potential to prevent cancer, and cardiovascular and neurodegenerative diseases.
