Early warning aigns of Alzheimer's show up across cognitive areas years before official diagnosis

By combing through dozens of Alzheimer's disease (AD) studies, psychologists have gained a clear picture of cognitive problems in people who will develop the degenerative brain disease.

Natural killer cells help understand responses to bone marrow transplants

Scientists have discovered that a group of important immune system cells has a surprising resemblance to cinematic British superspy James Bond: the cells receive a "license" that allows them to unleash their most potent attacks on enemies.

MDMA/Ectasy could lead to new treatments for Parkinson's disease

Researchers at Duke University have revealed new clues about Parkinson's disease which might one day lead to new treatments.

New breast cancer genes detected using cutting edge technology

Scientists in the UK say they have detected four new genes believed to be involved in the development of breast cancer.

New insights into dietary divergences between some of our human ancestors

A Penn State researcher is part of the team that developed techniques that have generated insights into dietary divergences between some of our human ancestors, allowing scientists to better understand the evolutionary path that led to the modern-day diets that humans consume.

Researchers pinpoint specific cause of defects in motor learning in Fragile X patients

While researchers have long known the genetic defect underlying Fragile X syndrome, they are still tracing how that defect creates the complex mix of mental retardation, hyperactive behavior, attention deficits, and other problems in the disorder.

Scientist have found an unexpected effect of the interaction of PTEN and p53 genes in early stage prostate cancer

Prostate cancer, the second leading cause of cancer death for men in the United States, is caused by changes in several tummor suppressor genes including PTEN and p53. Up to 70 percent of men with prostate cancer have lost one copy of the PTEN gene at the time of diagnosis, and p53 is absent in a high number of patients with advanced prostate cancer.

Melanoma is being overdiagnosed

New research published online by the British Medical Journal (BMJ) today (Thursday 4 August 2005) suggests that melanoma is being overdiagnosed in the United States.

Alcohol linked to an increased risk of upper gastrointestinal cancer

Researchers looking for the potential biochemical basis for this link have focused on acetaldehyde, a suspected carcinogen formed as the body metabolizes alcohol.

Obesity's effects on mortality may have been over-estimated

New research shows that obese adults who reach the age of 70 are at no greater risk of dying than their non-obese counterparts, but they do have a much greater probability of spending their remaining years disabled. The data supporting this is reported in the August 2005 issue of The Gerontologist (Vol. 45, No. 4).

Breakthrough in Alzheimer's research

This week scientists of the Flanders Interuniversity Institute for Biotechnology (VIB) will once again publish a breakthrough in their research regarding Alzheimer's disease.

First evidence that complex genetic interactions account for autism risk

Using a novel analysis of the interactions among related genes, Duke University Medical Center researchers have uncovered some of the first evidence that complex genetic interactions account for autism risk. The Duke team found that the brain mechanism that normally stops or slows nerve impulses contributes to the disease.

Breed and placement affect skin drug delivery

Skin creams and patches might be the easiest way to give your pets medicine but their success also depends on the breed and where it’s applied.

New hope for schizophrenia sufferers

Key research from the University of New South Wales (UNSW) could lead to the first early diagnostic tool for schizophrenia and bipolar disorder.

Customized gene chip offers clues to prognosis in cases of neuroblastoma

Rather than covering the entire genome, the microarray focuses on suspect regions of chromosomes for signs of deleted genetic material known to play a role in the cancer.

Relationship between allergies and mold spores in lawns

"Have you ever driven down the road and seen someone mowing the lawn wearing a mask? This is an example of the relationship between allergies and mold spores in lawns. Dr. Phil Colbaugh, research plant pathologist at the Texas Agricultural Experiment Station in Dallas, cites a common image seen in Texas throughout the warm weather months.

Researchers find C-reactive protein differences, a predictor of heart disease among sexes, races

A protein in the blood that is considered to be a key indicator of future heart disease may vary considerably among women and men, as well as blacks and whites, according to new research at UT Southwestern Medical Center.

Strategic analyses of European In-Vitro cancer diagnostics market - Cancer research yields promising results

Every year, nearly one in four Europeans - a total of almost one million people - dies from cancer, giving Europe the dubious distinction of having amongst the highest cancer-related mortality rates in the world. Even as cancer remains a difficult disease to diagnose, often resulting in either poor diagnosis or misdiagnosis, the number of new cancer cases is set to double by 2020.

Research to investigate new drug for Parkinsons disease

Researchers at the University of Sydney have received a grant to investigate the potential of a new drug to treat the abnormal posture and balance that affects people with Parkinson's disease ultimately confining them to a wheelchair.
