Adding nitric oxide to blood in blood banks may preserve life giving properties

Researchers in the United States say one of the reasons why many patients do not do well after blood transfusions is because donated blood rapidly loses some of its life-saving properties.

UF researchers test stem cell therapy for heart patients

University of Florida doctors on Wednesday (Oct. 3) treated their first patient enrolled in a new study designed to test whether injecting stem cells into the heart helps restore blood flow to the organ by prompting new blood vessels to grow.

Sex after chronic heart failure

Although medication can help extend the lives of men with chronic heart failure, several factors associated with this disease can interfere with a person's ability to engage in and enjoy sexual activities.

Tiny micro-incubator to culture living cells for lab tests

Integrating silicon microchip technology with a network of tiny fluid channels, some thinner than a human hair, researchers at The Johns Hopkins University have developed a thumb-size micro-incubator to culture living cells for lab tests.

Avoiding sweets may spell a longer life

A new study in the October issue of Cell Metabolism, a publication of Cell Press, reveals that worms live to an older age when they are unable to process the simple sugar glucose.

Daisy compound used to attack cancer stem cells

A new, easily ingested form of a compound that has already shown it can attack the roots of leukemia in laboratory studies is moving into human clinical trials, according to a new article by University of Rochester investigators in the journal, Blood.

Mini-strokes linked to uric acid levels

Researchers at Johns Hopkins have found that high-normal uric acid (UA) levels may cause barely detectable mini strokes that potentially contribute to mental decline in aging adults.

Better use of kidneys from deceased donors

Several new studies suggest how transplant surgeons can make more effective use of kidneys from deceased donors – even those that are at the outer limits of acceptance criteria – according to researchers from Wake Forest University Baptist Medical Center.

Stealth learning fosters science education

Rochelle Schwartz-Bloom, a Duke University pharmacology professor who left the lab bench to focus on science education, has developed a tactic for keeping students hands in the air at the end of class.

Organically modified silica nanoparticles with covalently incorporated photosensitizer for photodynamic therapy of cancer

Photodynamic therapy, in which light activates a chemical known as a photosensitizer, triggering the production of cell-killing reactive oxygen, has proven itself as an effective therapy for a limited number of cancers.

Hydrogen sulfide based drug shows promise in reducing heart-attack damage

Producing a state of "hibernation on demand" in mice by administering an experimental drug from Ikaria (an injectable formulation of the biological gas hydrogen sulfide) showed promise in a study designed to reduce damage from heart attacks.

WHO essential emergency training to save lives and prevent disability

WHO is expanding its programme to train health care staff in low- and middle-income countries in essential emergency, basic surgery and anaesthesia skills.

Process of necrosis redefined in landmark study

A new study led by investigators from the University of Pittsburgh School of Medicine demonstrates that the process of necrosis, long thought to be a chaotic, irreversible pathway to cell death, may actually be triggered as part of a regulated response to stress by a powerful protein, SRP-6, that can potentially halt necrosis in its path.

New discovery on blood doping and anemia

A stunning discovery by German scientists may make blood doping and the treatment of severe anemia as easy as washing your hair.

Ancient mechanism for coping with stresses also gives cancer a boost

An ancient mechanism for coping with environmental stresses, including heat and toxic exposures, also helps cancerous tumors survive, reveals a new report in the Sept. 21, 2007, issue of Cell, a publication of Cell Press.

Hydrogen sulfide limits severe heart attack damage

Administering hydrogen sulfide (H2S) directly into the heart during a simulated heart attack significantly reduces the tissue and cell damage often seen in oxygen-starved organs, according to a new study from researchers at the University of Alabama at Birmingham

Researchers look at role of oxidative stress in human diseases

Oxidative stress is known to underlie many human diseases including atherosclerosis, Parkinson's disease and Alzheimer's disease.
