Does physical activity provide a molecular key to longevity?

Fitness and physical exercise are among the most neglected means to improve prognosis. They are the healthiest cardiovascular intervention. Even cardiologists focus on pharmacological treatment and evaluate classical risk factors without asking about daily exercise or objective measures of physical capacity. It is surprising considering the strong data that underscores the survival benefit of regular exercise training.

Ultrasound to seal punctured lungs

A stretcher races through the entrance of a busy hospital. The car-accident victim lies on top and grimaces in pain. While surface injuries look gruesome, the real medical danger is invisible - internal organ damage caused by being crushed against the steering wheel.

Protein on the surface of platelets plays a key role in cancer-induced platelet aggregation

Scientists have provided new details about how cancer cells spread by surrounding themselves with platelets – the blood cells needed for blood clotting.

Big leap in genomic screening of blood vessels from patient tissue

Scientists have developed a new method of capturing a complete genome-wide screening of blood vessel cells in their actual disease state, advancing the potential for genetic research on the tissue responsible for delivering nourishment that can accelerate the growth of both a cancer tumor or wound healing.

FDA approves Evithrom (human thrombin)

The U.S. Food and Drug Administration has approved Evithrom (human thrombin), a blood-clotting protein used to help control bleeding during surgery.

Early heart treatment can reverse damage

University of Minnesota researchers have discovered that treating people who have early cardiovascular abnormalities, but show no symptoms of cardiovascular disease, can slow progression and even reverse damage to the heart and blood vessels.

New understanding of what makes a major global bacterial infection deadly

Researchers believe they have discovered why a bacterial lung infection is so lethal in the early stages, and it's not what medical authorities had thought, according to research published in the journal Immunity.

Novel heart repair therapy could be in the pipeline

The success of a new and experimental stem cell treatment used in animals could lead to a novel heart repair therapy for heart attack patients.

New way to control hypertension may lead to more effective drugs

British scientists say they have found a new way to regulate hypertension (high blood pressure).

Australian researchers discover a 'novel molecular dictator with a conscience'

University of New South Wales (UNSW) researchers have uncovered an important naturally occurring mechanism in the body where "bad" cells that cause blockages in our blood vessels are kept under strict growth control, while "good" cells that keep our blood vessels free of clots and growths are left unaffected.

Sildenafil increases release of key reproductive hormone oxytocin

Researchers at the University of Wisconsin-Madison report this month that sildenafil increases the amount of oxytocin released by stimulation of the posterior pituitary gland, a small structure directly underneath the brain that regulates hormone levels in response to neural signals.

Blocking angiogenesis signaling from inside cell may lead to serious health problems

Angiogenesis inhibitors that block a tumor's development of an independent blood supply have been touted as effective cancer fighters that result in fewer side effects than traditional chemotherapy.

Study helps predict anesthesia-linked risks for children with chest tumors

Children with mediastinal masses - tumors in their chest outside the lungs - are at special risk for developing breathing problems when they undergo anesthesia. These young patients are of special concern to clinicians who must anesthetize them as part of their medical treatment.

High altitude pulmonary oedema

Experts at the University are studying an illness known as HAPE (high altitude pulmonary oedema), which causes fluid to build up in the lungs can and can occur from as low as 2,500 metres, affecting people of all age groups and fitness levels.

High-density diffuse optical tomography helps scan infant brains

Researchers hoping to better understand the development of the infant brain have long been stymied by a formidable obstacle: babies just don't want to sit still for brain scans.

We need to treat cancer like an infectious disease

Among the many medical miracles produced by science over the years, vaccines and antibiotics have undoubtedly saved the most lives.

Organ-transplant drug may help fight lupus

A compound related to a drug used in humans to prevent organ-transplant rejection attacks a key biochemical process in the faulty immune cells of lupus-prone mice, suggesting a possible new approach to combating the disease, UT Southwestern Medical Center researchers have found.

Sex differences in response to vasoactive substances in early uncontrolled diabetes

Diabetes is associated with the development of vascular (blood vessel) disease. As we age, vascular disease becomes more common.

Age-related macular degeneration patient receives investigational eye drops

An 88-year-old man at The Methodist Hospital in Houston is one of two patients in the world today to receive an investigational eye drop that may restore sight for those suffering from neovascular (wet) age-related macular degeneration, a major cause of central visual loss and one of the leading causes of blindness in people over 60 in the United States.

Cytokines shown to be a cause of type 2 diabetes

In the first large scale, multiethnic study of its kind, researchers at UCLA have confirmed the role played by three particular molecules known as cytokines as a cause of Type 2 diabetes, and further, have identified these molecules as early biological markers that may be used to more accurately predict future incidences of diabetes among apparently healthy individuals.
