Angiogenesis : Blocking tumor growth and treating infarction - a new target

Our tissues are able to form new blood vessels throughout life. This mechanism, which is called angiogenesis, is essential notably in the case of myocardial infarction, stroke and limb ischemia. The very same mechanism, however, keeps tumors supplied with nutrients and oxygen thus enabling them to continue growing.

Elderly lung cancer patients tolerate combined chemotherapy and radiotherapy with no higher risk of death than younger patients

Lung cancer remains the leading cause of cancer deaths in the U.S., with half of those diagnosed at age 70 years or older. About 20 percent of patients with lung cancer will have small cell lung cancer (SCLC). In the past, SCLC progressed rapidly despite initial chemotherapy sensitivity and few patients survive three years.

Reduction in oxygen levels greater problem as modern aeroplanes cruise to higher altitudes

More than half of air travellers find that their oxygen saturation drops to a level at which many hospital patients would be prescribed extra oxygen, according to a paper in the May issue of Anaesthesia.

Fatness, despite fitness, is linked with cardiovascular risk factors

Body fatness was associated with more cardiovascular disease risk factors even among healthy, aerobically fit men, according to a report today in an obesity-themed issue of Circulation: Journal of the American Heart Association.

Scientists have, for the first time, induced a state of reversible metabolic hibernation in mice

Scientists at Fred Hutchinson Cancer Research Center have, for the first time, induced a state of reversible metabolic hibernation in mice. This achievement, the first demonstration of "hibernation on demand" in a mammal, ultimately could lead to new ways to treat cancer and prevent injury and death from insufficient blood supply to organs and tissues.

Using light under your skin

You have a tiny wound on your hand that doesn’t heal, a bad burn on your chest – or an injured retina. Your doctor cannot tell how serious the injuries are below the surface. He needs tissue samples. That means using a scalpel, which again equals pain, perhaps even a risk. Soon there may be hope for an improved and totally harmless method to peer under the surface of the skin: light.

Mice put into "suspended animation" in U.S.

Researchers from the University of Washington and the Fred Hutchinson Cancer Research Centre in Seattle have placed mice in a state of near suspended animation, raising the possibility that in future hibernation could be induced in humans.

Body's 24-hour internal clock linked to obesity and diabetes

Obesity and diabetes in both adults and children are rising at alarming rates and a wide range of culprits -- super-sized food portions, lack of exercise due to television, computers, suburban sprawl and loss of gym classes, high-fat and fast foods, sugar-laden drinks and psychological trauma -- have been blamed.

Hospitalized babies with severe breathing problems may benefit from lying on their stomachs

Infants who are hospitalized with severe breathing problems may benefit from being placed on their stomachs rather than their backs, according to a new review of recent studies.

Some Alzheimer’s patients can benefit from drug Memantine

The drug memantine can reduce cognitive deterioration and loss of everyday functions in patients with moderate to severe Alzheimer’s disease, according to a new review of studies.

Alternate view for pathology of Alzheimer's disease

A new paper from researchers at the Case Western Reserve University School of Medicine challenges the classic theory that the nerve tangles seen in the brains of Alzheimer's disease (AD) victims are the cause of the disease, but rather proposes that they are a protective response to the disease. Their paper appears in the April issue of the journal Trends in Molecular Medicine.

Eat your fruits and veggies - your body will thank you and your mother will be happy!

Eat your fruits and veggies - your body will thank you and your mother will be happy! And if that's not reason enough, a new study suggests antioxidant-rich fruits and vegetables may limit brain damage from stroke and other neurological disorders.

Researchers discover mechanism by which tumours support their own growth

In a recent issue of the American Journal of Pathology, the Bremen researchers report their findings on a signalling molecule called "High Mobility Group Protein B1" (HMGB1). As a signal sent by tumour cells HMGB1 proteins induce sprouting of blood vessels that supply tumours with oxygen, thus promoting tumour growth.

Hemodialysis causes antioxidant loss leading to long-term complications

An article published in Hemodialysis International discusses the role of oxidative stress (OS) in dialysis patients, an imbalance which can result in long-term health problems. Potential therapeutic options to restore balance in patients are also reviewed.

New technology to help heart and lung patients awaiting transplants

Promising new technology may extend the life of a failing organ for patients suffering from heart or lung disease while they wait for a donor organ. The use of stem cells may eliminate the need for a transplant and even eradicate heart disease in patients.

How heart is formed in the embryo helps explain congenital heart disease

Children's Hospital of Pittsburgh Cardiologist Bradley B. Keller, MD, and his research team are discovering details in the lab that explain how the heart is formed in the embryo. This knowledge improves the chances of doctors identifying fetuses who can benefit from intervention to treat congenital defects.
