Experimental approach may improve healing of diabetic wounds and bed sores

MAYWOOD, Ill. -- Loyola University Health System researchers are reporting on a promising new approach to treating diabetic wounds, bed sores, chronic ulcers and other slow-to-heal wounds.

It may be possible to speed healing by suppressing certain immune system cells, researchers wrote in the February, 2011, issue of the journal Expert Review of Dermatology.

Lack of sleep found to be a new risk factor for colon cancer

An inadequate amount of sleep has been associated with higher risks of obesity, heart disease, diabetes, and death. Now colon cancer can be added to the list.

Income inequalities are increasing the occurence of depression during financial crisis

Due to the recent economic crisis, an increase of health inequalities between socio-economic groups has been noticed in both developed and developing countries.

The World Health Organization, the World Bank and the United Nations Development Programme have all reported these inequalities and emphasized its importance and made this issue a priority.

There is evidence that such inequalities not only affect general health, but have a particular impact on mental health.

The great tonsil dilemma

ANN ARBOR, Mich. — Without fanfare, hundreds of thousands of children surrender their tonsils to a surgeon's scalpel each year, usually to alleviate recurring infections and obstructive sleep problems. Most of the time, the snipped tonsils are sent to a pathologist, who looks for evidence of more serious medical problems, like unsuspected cancer.

But this common practice may not be cost-effective because those additional examinations rarely lead to the discovery of hidden disease, a new University of Michigan Heath System analysis shows.

When worms stick together and swim on thin water, what happens and why does it matter?

Nematodes, microscopic worms, are making engineers look twice at their ability to exhibit the "Cheerios effect" when they move in a collective motion.

These parasites will actually stick together like Cheerios swimming in milk in a cereal bowl after a chance encounter "due to capillary force." This observation has made Virginia Tech engineers speculate about the possible impacts on the study of biolocomotion.

In February journal, UC and industry researchers predict future of electronic devices

Heikenfeld is part of an internationally prestigious UC team that specializes in research and development of e-devices.

New data obtained on liposomes employed in drug encapsulation and gene therapies

University of Granada scientists and the Spanish Higher Institute for Scientific Research (CSIC) have made significant progress in understanding lipid membranes, which are extensively employed in the development of cosmetic and drug products, and which have potential application in the field of nanotechnology.

Western Australia's incredible underground orchid

Rhizanthella gardneri is a cute, quirky and critically endangered orchid that lives all its life underground. It even blooms underground, making it virtually unique amongst plants.

Last year, using radioactive tracers, scientists at The University of Western Australia showed that the orchid gets all its nutrients by parasitising fungi associated with the roots of broom bush, a woody shrub of the WA outback.

Now, with less than 50 individuals left in the wild, scientists have made a timely and remarkable discovery about its genome.

Eggs are now naturally lower in cholesterol

Park Ridge, IL (February 8, 2011) – According to new nutrition data from the United States Department of Agriculture's Agricultural Research Service (USDA-ARS), eggs are lower in cholesterol than previously thought. The USDA-ARS recently reviewed the nutrient composition of standard large eggs, and results show the average amount of cholesterol in one large egg is 185 mg, 14 percent lower than previously recorded. The analysis also revealed that large eggs now contain 41 IU of vitamin D, an increase of 64 percent.

Turning off stress

Post-traumatic stress disorder can affect soldiers after combat or ordinary people who have undergone harrowing experiences. Of course, feelings of anxiety are normal and even desirable – they are part of what helps us survive in a world of real threats. But no less crucial is the return to normal – the slowing of the heartbeat and relaxation of tension – after the threat has passed. People who have a hard time "turning off" their stress response are candidates for post-traumatic stress syndrome, as well as anorexia, anxiety disorders and depression.

Using pharmacist-directed service improves quality of care for patients

DETROIT ¬– A Henry Ford Hospital study has found that a pharmacist-directed anticoagulation service improves the way medication is managed for patients with heparin-induced thrombocytopenia (HIT), a common but life-threatening thromboembolic disorder.

Researchers found that patients treated by the anticoagulation service had a favorable response to alternative anticoagulant drugs three times faster and were 32 percent more likely to receive proper dosage than patients who were treated with the same drugs by the patient's primary medical team.

Late nights can lead to higher risk of strokes and heart attacks

New research from Warwick Medical School published today in the European Heart Journal shows that prolonged sleep deprivation and disrupted sleep patterns can have long-term, serious health implications. Leading academics from the University have linked lack of sleep to strokes, heart attacks and cardiovascular disorders which often result in early death.

Speedy generic approval may not benefit consumers as much as expected, Rotman model shows

Toronto – Faster approval times for generic drugs will get them into consumers' hands quicker, but may not make the price any better, a pricing and marketing researcher has found.

A mathematical model created by Andrew Ching shows that fewer firms enter the marketplace because the chances of getting there first and commanding the best profits are dramatically smaller when drug approval times are shorter. Ching is an associate professor of marketing at the University of Toronto's Rotman School of Management.

Pollution controls used during China Olympics could save lives if continued

CORVALLIS, Ore. – The air pollution control measures that were put in place in Beijing during the 2008 Olympic Games – if continued – would cut almost in half the lifetime risk of lung cancer for the area's residents from certain inhaled pollutants, a new study concludes.

This might translate to about 10,000 fewer lifetime cases of lung cancer in this large metropolitan area, scientists said, which is only one of several in China that have unhealthy levels of air pollution, largely from the burning of coal, biomass and automobile exhaust in a rapidly growing economy.

As many as 3 in 4 hospital tests not followed up after discharge

Up to three quarters of hospital tests are not being followed up, suggests a systematic review of international evidence, published in BMJ Quality and Safety.

This failure can have serious implications for patients, including missed or delayed diagnoses and even death, the study shows.

The authors base their findings on a systematic review of evidence published in English between 1990 and 2010, and available on reputable research databases.
