Why some people are better looking!

Researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different?

How the brain processes pain location

Is that pain in your chest a heart attack or indigestion? New research from Wake Forest University School of Medicine reveals that more areas of the brain than previously thought are involved in determining the location of pain.

Adding estradiol to a polymer-free rapamycin-eluting stent is not associated with any measurable benefit

Patients admitted to the hospital with acute coronary syndromes (ACS) are often treated with a catheter-based procedure known as percutaneous coronary intervention (PCI), during which a stent is inserted into an occluded or narrowed coronary artery to restore blood flow to and from the heart.

Health care providers should directly address issues surrounding death and dying with homeless patients

To study homeless persons' attitudes and experiences with death and end-of-life care, the researchers conducted focus groups through Twin Cities service providers who work with homeless persons.

Xenotransplantation - what are the barriers?

Given the huge shortage of donor organs, researchers have been trying to find ways to transplant animal organs across different species (known as "xenotransplantation"), with the eventual aim of transplanting animal organs into humans.

Synthetic molecule helps detect heart attack in the making

A new bright spot in heart disease research may soon allow physicians to peer directly into patients' blood vessels and find dangerous cholesterol-filled plaques before they rupture and cause a heart attack.

Scientists invent way to reversibly silence brain cells using pulses of yellow light

Scientists at the MIT Media Lab have invented a way to reversibly silence brain cells using pulses of yellow light, offering the prospect of controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease.

Magnetic system could provide surgery without scars

Physicians at UT Southwestern Medical Center and engineers at UT Arlington have collaborated to invent a groundbreaking system that could be key to delivering on the promise of surgery without scars.

Maternal beef consumption associated with lower sperm concentration

New research has shown that women who ate a lot of beef while pregnant had sons who were more likely to suffer from poor sperm quality as adults, and it suggests that the growth promoters used in cattle may play a role in these men's reduced fertility.

Synthesis, characterization, DNA binding and in vivo activity of Ru(II)/Pt(II) complexes

Chemists and biologists at Virginia Tech continuing to design light-activated molecular systems to attack cancer cells have introduced a DNA targeting component.

Validation of an LED array for use in DNA photocleavage assays

Biology and chemistry researchers from Virginia Tech are creating molecular complexes to bind to and disrupt the DNA of diseased tissues, such as tumors or viruses.

Major step forward for islet transplantation in diabetes patient

Living Cell Technologies Limited has announced it has published evidence outlining the survival and identification of live porcine islet cells and insulin production in a human patient 10 years after receiving a pig islet cell transplant.

Lack of Olig1 protein in lung tumors may increase risk of death

A study of human lung tumors indicates that lung cancer patients who lack a particular protein may do more poorly than those with normal levels of that same protein.

Drug-eluting stents are disappointing in bypass grafts - sometimes!

While drug-eluting stents are effective in keeping open bypassed heart veins that aren?t too diffuse (filled with cholesterol plaque), a new study by cardiologists at Jefferson Medical College shows that they fare less well in keeping open bypassed veins with longer blockages.

Clearer picture of neuronal coding

The validity of a leading theory that has held a glimmer of hope for unraveling the intricacies of the brain has just been called into question.

Reconstituted HDL may have some benefit in coronary atherosclerosis

Preliminary research suggests that use of reconstituted HDL may have some benefit in coronary atherosclerosis, according to a JAMA study published online March 26.

Infants emotional understanding

Infants use indirect emotional information, emotional reactions that are directed at other people, to guide their own behavior.

Immunity to cancer stem cells may help protect people with a precancerous condition from developing the full-blown disease

Although stem cells hold incredible promise in the fight against certain diseases, in cancer they're anything but helpful. In fact, mounting evidence is showing that a tumor's growth and spread may depend on "cancer stem cells," which comprise only a very small subset of the tumor.

African Americans may be at higher risk of heart failure because of racial variations in heart muscle's pumping ability

Scientists have known for nearly a decade that African Americans have higher rates of hospitalization for heart failure than other major U.S. racial or ethnic groups, but until now they have had limited information other than socio-economic and demographic characteristics to explain why this is so.
