Study confirms increased heart attack deaths in NYC ambulance diversions

Ambulance diversions from nearby, crowded New York emergency rooms to more distant emergency departments are associated with increased deaths among patients suffering from heart attacks, according to a paper presented at a meeting of the Institute for Operations Research and the Management Sciences (INFORMS®).

Forced evolution: Can we mutate viruses to death?

HOUSTON -- Nov. 10, 2008 -- It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence. The killer disease? Still a fiction. The drug? It could become a reality thanks to a new study by Rice University bioengineers.

Researchers describe how cells take out the trash to prevent disease

Garbage collectors are important for removing trash; without them waste accumulates and can quickly become a health hazard. Similarly, individual cells that make up such biological organisms as humans also have sophisticated methods for managing waste.

For example, cells have developed complex systems for recycling, reusing and disposing of damaged, nonfunctional waste proteins. When such systems malfunction and these proteins accumulate, they can become toxic, resulting in many diseases, including Alzheimer's, cystic fibrosis and developmental disorders.

Researchers discover method for mass production of nanomaterial graphene

Graphene is a perfect example of the wonders of nanotechnology, in which common substances are scaled down to an atomic level to uncover new and exciting possibilities.

Research hightlights, AAO-SOE Joint Meeting, Nov. 9 sessions

ATLANTA— The 2008 Joint Meeting of the American Academy of Ophthalmology (Academy) and European Society of Ophthalmology (SOE ), the largest and most comprehensive ophthalmic educational meeting in the world, is in session November 8 to 11 at the Georgia World Congress Center, Atlanta. Offerings include 277 continuing medical education courses, 179 "Breakfast with the Experts" roundtables, 95 skills transfer courses, and more than 100 hours of scientific presentations, at no charge.

In the absence of sexual prospects, parasitic male worms go spermless

When females aren't around, one species of parasitic nematode worm doesn't even bother to make any sperm, reveals a new report in the November 11th issue of Current Biology, a Cell Press publication.

Genetic blueprint revealed for kidney design and formation

CINCINNATI – Researchers have generated the first comprehensive genetic blueprint of a forming mammalian organ, shedding light on the genetic and molecular dynamics of kidney development.

SNPs affect folate metabolism in study of Puerto-Rican adults

BOSTON (November 10, 2008) — Researchers at Tufts University have gained further understanding of the genomic basis for altered folate metabolism and the content of uracil in blood DNA.

Study shows direct link between leptin and obesity-related cardiovascular disease

ATHENS, Ohio (Nov. 10, 2008) – Obese people who don't have high cholesterol or diabetes might think they're healthy – despite the extra pounds. But new Ohio University research suggests that obesity raises levels of the hormone leptin, which can be as big a threat to the cardiovascular system as cholesterol.

Nature’s own chemical plant

Petroleum is the feedstock for many products in the chemical industry. However, this fossil fuel is becoming increasingly scarce and expensive. Renewable raw materials are an alternative. But can the likes of bioethanol be obtained from sources other than foods such as sugar cane or cereals? The answer is yes. Thanks to white industrial biotechnology, chemical substances can also be derived from waste products generated by the food industry, leftover biomass from agriculture and forestry, and residual materials.

Study improves recovery for mothers with depression

Scientists at the University of Liverpool have developed a therapy programme to treat depression in women in developing countries.

Although depression is a major health problem world-wide, experts say its impact is greatest in developing countries where 80% of the population live. Often there are no resources available to treat sufferers.

Professor Atif Rahman from the School of Population, Community and Behavioural Sciences developed a therapy programme while working as a Wellcome Trust Career Fellow in Tropical Medicine in Rawalpindi, Pakistan.

White vans goes green

As if the drivers of mini vans and utility vehicles needed any more encouragement to drive fast between jobs, US researchers have designed a new rear spoiler for bluff-backed vehicles that can reduce drag and lift significantly. Writing in the International Journal of Vehicle Design, the team describes how the new spoiler could improve fuel consumption as well as vehicle handling.

Researchers aim to over-stress already taxed mantle cell lymphoma cells

AUGUSTA, Ga. - Cancer cells are already stressed by the fast pace they require to grow and spread and scientists believe a little more stress just may kill them.

"Think about an assembly line in a factory that is working five times faster than normal," said Dr. Kapil Bhalla, director of the Medical College of Georgia Cancer Center. "There is a lot of stress but you need workers to keep going. Some of them fall out, some get bent out of shape."

Indigenous Australian patients confused and frustrated by kidney disease

New Australian research has shown that Indigenous Australians with kidney disease are confused, frustrated and feel poorly informed about their illness.

The study reveals Indigenous Australian's feel inadequately informed and are considerably more uncertain about the cause of their illness compared to non-Indigenous patients with kidney disease. The results of the large qualitative study are published in the Medical Journal of Australia.

Heart's surplus energy may help power pacemakers, defibrillators

Surplus energy generated by the heart may one day help power pacemakers and defibrillators implanted in cardiac patients, according to research presented at the American Heart Association's Scientific Sessions 2008.
