Innovative coating could give medical implants a longer life

By mimicking an adhesive protein secreted by mussels and a polymer that repels cells and proteins, researchers at Northwestern University have designed a versatile new two-sided coating that could breathe life into medical implants. Currently the longevity of certain medical implants suffers because bacteria, cells and proteins in the body gradually accumulate on the devices (known as fou...

Fluorescing lab worms signal longer life spans

University of Colorado at Boulder scientists have used a fluorescent marker to predict the individual life spans of identical worms that were genetically engineered to illuminate stress levels, implying living organisms have "hidden physiological states" that dictate their ability to deal with the rigors of life. According to CU-Boulder Research Associate Shane Rea, the genetically identic...

Discoveries by UAB and Florida scientists may help transplanted organs survive longer

Scientists may have found a way to dramatically slow organ transplant rejection by as much as several years. The research team reporte...

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic according to a new study to be published in the Sept. 22, 2005, issue of Science Express. The resulting atmospheric heating in the region of northern Alaska is equivalent to...

New antifreeze protein found in fleas may allow longer storage of transplant organs

A new antifreeze protein discovered in tiny snow fleas by Queen's University researchers may lengthen the shelf life of human organs for transplantation. Drs. Laurie Graham and Peter Davies, from the Department of Biochemistry, found that the potent protein produced by the fleas to protect themselves against freezing is capable of inhibiting ice growth by about six Celsius degrees. This wo...

Longer airway in males increases sleep disorder risk

Researchers have built a new model of the airway, which shows an important gender difference that has health implications. In sleep apnoea, the upper airway tends to collapse during sleep causing an obstruction to the free flow of air.// This actually causes breathing to stop momentarily many times in the night, leading to daytime sleepiness and a higher risk of heart disease and stroke....

Treatment over a longer period for blood clotting

Venous thromboembolism is a condition which causes clotting in the veins. Typical therapy for venous thromboembolism includes a five- to 10-day course of heparin followed by three to 12 months of the oral drug warfarin. However, the problem with this treatment is that once the patient goes off warfarin, venous thromboembolism recurs. While recurrence rates of this problem are reduced if the patie...

Dads to blame for longer pregnancies

Danish researchers led by Annette Wind Olsen have reported in the BritishMedical Journal that fathers might be responsible for pregnancies that lastlonger than 42 weeks or 294 days. The condition of prolonged pregnancies affectsaround 5% of pregnant mothers. The researchers conducted a study of about 28,000women between 1980 and 1994. About 21,000 women in the group had a firstpregnancy...

Longer Lung Cancer Survival

According to the American Cancer Society, there are 172,000 Americans diagnosed with lung cancer each year. Because there are no early screening tests, many of these cancers are caught in their later stages, making them difficult to treat. A new drug is now helping patients who have failed standard treatment. By going after that protein, the drug stops the cancer from growing. Studies show...

Meditation may reduce stress and help you live longer

Stressful lifestyle can contribute heavily to high blood pressure and cardiovascular disease//. A new study has revealed that distressing can happen through transcendental meditation programs that can lead to prevention and control of these diseases. For population over 55 years of age, those who live the extreme stressful life, interventions in the form of meditation may have long-ter...
