Natural selection has played an important role in patterning the human genome

The most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species, according to researchers from Cornell University, Celera Genomics and Celera Diagnostics.

More than half of Norwegian doctors surveyed prescribe themselves medication

A study published in the open access journal BMC Medicine reveals that a large number of doctors in Norway start self-prescribing early after graduation and continue doing so well into their career - a finding that is likely to be mirrored in other western countries.

Acid reflux disease - surgery has longterm success rate

According to a study published this week, surgery to cure acid reflux disease, the most severe form of heartburn, has shown a high degree of long-term success.

New treatment advances for patients with follicular lymphoma

A newly published study recommends that doctors carefully choose their patients' initial therapies because there are significant differences in overall survival rates, according to researchers at the University of Rochester Medical Center's James P. Wilmot Cancer Center.

Defibrillators plentiful in schools but not senior centers

A greater percentage of high schools had automated external defibrillators (AEDs) - devices that can be used to treat cardiac arrest victims - than senior centers, despite the fact that cardiac arrests appear more common in senior centers, according to a study by University of Iowa researchers.

Link between emotional impairment and poor cognition in children with bipolar disorder

Using functional magnetic resonance imaging, Pavuluri and her colleagues examined the brain activity of teens while they were performing certain mental tasks. The researchers scanned the brains of 10 unmedicated bipolar patients with normal mood and compared them with 10 healthy subjects of the same age and gender.

Diet rich in fruits and vegetables could be a good defense against prostate cancer

Previous studies have suggested that increased intake of flavonoids which are common in fruits and vegetables may be associated with a reduced risk of prostate cancer, according to Sanjay Gupta, Ph.D., an assistant professor in the Case School of Medicine Department of Urology.

Breast cancer drug Herceptin a 'stunner'

According to the New England Journal of Medicine (NEJM) the first trials of the breast cancer drug, Herceptin, tested on women with early stage disease are "simply stunning".

Award for genetic study that revolutionised thinking on epilepsy

Melbourne researcher, Professor Sam Berkovic, has been awarded the prestigious Zulch Prize from the Max Planck Society in Germany in recognition of his groundbreaking investigations into the genetic foundations of epilepsy.

"Junk" DNA not important to an organism's evolutionary survival

Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at the University of California, San Diego.

Medicare patients have a substantially higher risk of early death following bariatric surgery than previously suggested

...and the risk of death is higher among men, older patients, and patients of surgeons who perform lower numbers of bariatric procedures, according to a study in the October 19 issue of JAMA: The Journal of the American Medical Association.

Blocking macrophage migration inhibitory factor molecule might prevent the progression of multiple sclerosis

A new study suggests that a substance made by immune cells plays a key role in the progression of a disease in animals that closely mimics multiple sclerosis (MS). The findings further suggest that blocking the molecule, known as macrophage migration inhibitory factor (MIF) might prevent the progression of the disease.

Consistently, African-Americans have been found to have worse health outcomes than whites

Ninety-five percent of older African-American clinic patients reported at least some exposure to racism during their lives in a study by researchers at the San Francisco VA Medical Center and the University of California, San Francisco.

Dust storms in Asia can have implications in geographically remote countries

Bacteria found in soil around Tokyo are not indigenous to the area. A study published in the BioMedCentral open access journal Saline Systems reveals a large proportion of salt-loving bacteria in non-saline soil around Tokyo. The researchers suggest that dust storms may have carried the bacteria from their natural habitats in China.

Herceptin results "quite remarkable"

The targeted drug trastuzumab, or Herceptin, previously shown to prolong survival in advanced breast cancer, dramatically reduced the chances of recurrence in patients with early-stage disease when given for one year following standard chemotherapy.

19 Oct 2005

Herceptin therapy highly superior to standard breast cancer treatment

In a joint paper, co-authored by Mayo Clinic's Edith Perez, M.D., and Edward Romond, M.D., of the National Surgical Adjuvant Breast and Bowel Project (NSABP), researchers report complete and combined results of two trials comparing adjuvant chemotherapy with or without concurrent trastuzumab treatment in women with surgically removed HER2-positive breast cancer.

Conjugated linoleic acid prevents inflammatory damage resulting from immune response

One of the isomers of conjugated linoleic acid, a group of fatty acids found in milk, is a natural regulator of the COX-2 protein, which plays a significant role in inflammatory disease such as arthritis and cancer, according to a study published by University of Wisconsin-Madison researchers.

Study of the effects of aripiprazole, olanzapine, quetiapine and risperidone, in elderly patients with dementia

Some newer antipsychotic medications may be associated with a small increased risk of death when used to treat elderly dementia patients, psychiatrists at Johns Hopkins warn.

Patients with head and neck cancer may be spared the risk and expense of surgery by undergoing a CT scan

Researchers with the UF Shands Cancer Center have identified criteria doctors can use to evaluate CT scans four weeks after patients undergo initial treatment. If these criteria are met, there is a 94 percent likelihood a patient's lymph nodes are cancer free, said Stanley L. Liauw, M.D., a resident in radiation oncology.

Drug-eluting stents significantly cut the rates of heart attack and repeat procedures

The use of medicated stents markedly improves the clinical outcomes of patients who develop blockages in aging veins surgically grafted onto the heart, according to a just-published study in the November 2005 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.
