Biomarker News and Research

RSS

A biomarker is a biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule.

Simple method to diagnose preeclampsia

Researchers at Yale School of Medicine have found that analyzing proteins in urine is a simple and objective method to diagnose and classify preeclampsia (PE), a complication of pregnancy causing high blood pressure after 20 weeks of gestation.

Inhaled corticosteroids most effective for persistent asthma in children

While both inhaled corticosteroids (ICS) and leukotriene receptor antagonists (LTRA) have been proven to help control mild-to-moderate persistent asthma in school-age children, a new study shows ICS may be the more effective treatment.

Value of prostate tests dubious

According to new research, men screened for prostate cancer using blood tests or digital examinations die of the disease at much the same rate as those who were not checked.

Prospect of personalized medicine places new demands on the evaluation of new medicines

As we enter the era of personalized medicine, it is time to take a fresh look at how we evaluate new medicines and treatments for cancer, according to Donald Berry, Ph.D., professor and chair of the Department of Biostatistics and Applied Mathematics at The University of Texas M. D. Anderson Cancer Center.

Elevated homocysteine levels may be a biomarker for increased risk of AMD

People who have elevated homocysteine in their blood, an amino acid that is a known biomarker for cardiovascular disease, may also be at an increased risk of developing age-related macular degeneration (AMD), according to a study in the January issue of the American Journal of Ophthalmology.

Brain volume may be used as an early detection system for dementia

Reduced volume, or atrophy, in parts of the brain known as the amygdala and hippocampus may predict which cognitively healthy elderly people will develop dementia over a six-year period, according to a study in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

New techniques are able to detect and monitor Alzheimer's disease

The search for new measures, or "biomarkers," to detect Alzheimer's disease (AD) before signs of memory loss appear has advanced an important step in a study by researchers at Washington University in St. Louis, MO, and the University of Pittsburgh.

DNA strands for biologically based electronics and medical devices

Ohio State University researchers have invented a process for uncoiling long strands of DNA and forming them into precise patterns.

New cancer detection method

University of Florida researchers say they are a step closer to a technique to easily detect a wide variety of cancers before symptoms become apparent.

Australian breast cancer study seeks participants

RMIT University researchers are seeking healthy, postmenopausal women to participate in a study to determine if diet and lifestyle can reduce the risk breast cancer.

New alcohol biomarker test lowers the cost of caring for patients with chronic illnesses

Adding a new alcohol biomarker test to patients' revelations about their drinking habits could lower the cost of caring for patients with chronic illnesses like diabetes and high blood pressure, a health economics analysis finds.

One-half of cancer patients continue to smoke after diagnosis

A pair of articles from The University of Texas M. D. Anderson Cancer Center makes the case that patients would receive better care if physicians and researchers would address the issue of tobacco use after a cancer diagnosis and monitor tobacco use during clinical trials that test new agents.

Smokeless tobacco products are not necessarily a safe alternative to smoking

According to the U.S. Centers for Disease Control and Prevention, nearly one-fourth of Americans are smokers. That's more than 60 million people who are at increased for lung cancer, the leading cause of cancer-related deaths nationwide.

Gene fusion appears to cause prostate cancer

Scientists at the University of Michigan Medical School, in collaboration with researchers at Harvard's Brigham and Women's Hospital, have discovered a recurring pattern of scrambled chromosomes and abnormal gene activity that occurs only in prostate cancer.

Gene found only in men is altered by a chemical process, which is in turn linked to aggressive forms of melanoma

New scientific evidence that may shed light on why men are more likely than women to develop aggressive forms of skin cancer has been published in Carcinogenesis.

Aβ and Fyn cooperate to cause Alzheimer-like changes in the brain

Reporting in two companion papers in the October 19 issue of the Journal of Neuroscience, investigators from the Gladstone Institute of Neurological Disease show in genetically engineered mouse models of the disease that the accumulation of Alzheimer-related neurotoxic amyloid-beta (Aâ) peptides can deplete key proteins in a specific memory center of the brain.

New prostate cancer test far more accurate

At present in order to predict prostate cancer outcomes, doctors rely on measures that suggest how far the tumour has spread and how abnormal the cancer cells appear under the microscope.

18 Oct 2005

Discovery could lead to tests for the clinic or battlefield to diagnose ailments with just a few drops of blood

A way to detect fragments of broken brain cells that leak into the bloodstream may help doctors more quickly and precisely treat people with severe head injuries or brain diseases, say researchers at the University of Florida's McKnight Brain Institute.

Researchers identify biomarker that indicates a more agressive form of prostate cancer

Staging factors for prostate cancer such as PSA and the Gleason score are extremely useful in predicting prostate cancer outcome," explained Pollack. "However, new biomarkers hold promise in strengthening our ability to predict response to treatment. By identifying the more virulent forms of prostate cancer, we may be able to tailor treatment or develop therapies to target the abnormalities identified."

Discovery of agent that can suppress cancer development

In a case of basic science detective work, researchers at The University of Texas M. D. Anderson Cancer Center have solved the puzzle of the "inconsistent biomarker" and, in the process, may have discovered an agent that can suppress cancer development.
