Defining biomarkers for better colon cancer treatment

Barcelona, Spain: New research has yielded a clearer picture of which biomarkers could help doctors more precisely target the treatment of colon cancer, bringing closer the day when patients who will not benefit from chemotherapy are spared it, while those that will, get the more aggressive treatment they need.

Discovery of new pathway causing cell death related to frontotemporal dementia and ALS

Scientists have discovered a link between a mutated gene and a protein found in dead brain cells of people who suffer from a form of dementia and other neurological disorders.

Research at Rice may help explain aspects of synesthesia

A research team led by Rice University Psychology Professor Tony Ro has published its findings that may help to explain the phenomenon known as synesthesia, in which stimulation of one sensory pathway leads to automatic, involuntary experiences in a second sensory pathway.

New molecular target in blood clot formation

Researchers at the University of Illinois at Chicago College of Medicine have identified a new molecular target in blood clot formation, which seems to reduce clotting without excessive bleeding, the common side-effect of anti-clotting agents.

The jury is in: microRNAs can cause tumors to metastasize

These tiny molecules fine-tune protein production and play a powerful role in biological processes ranging from development to aging. Now scientists have proved that they can prompt otherwise sedentary cancer cells to move and invade other tissues.

Transposons could make for safer gene delivery system

To move a gene from point A to point B, scientists and gene therapists have two proven options: a virus, which can effectively ferry genes of interest into cells, and a plasmid, an engineered loop of DNA that can do the same thing, albeit usually only on a short-term basis.

New research on glycemic index

In work investigating the reproducibility of glycemic index values, researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA) have reported that multiple glycemic index value determinations (measure of the rate of glucose absorption into the bloodstream) using a simple test food, white bread, resulted in a relatively high level of inter-individual (among different individuals), and intra-individual (within the same individual) variability.

Enzyme's second messenger contributes to cell overgrowth

Scientists at the University of California, San Diego (UCSD) School of Medicine have uncovered a novel pathway by which hormones elevated in inflammation, cancer and cell injury act on cells to stimulate their growth.

Discovery supports theory of Alzheimer's disease as form of diabetes

Insulin, it turns out, may be as important for the mind as it is for the body.

Alcohol cessation significantly reduces cancer risk

Researchers at the Centre for Addiction and Mental Health (CAMH) have clarified the link between alcohol consumption and the risk of head and neck cancers, showing that people who stop drinking can significantly reduce their cancer risk.

Scots second only to Americans when it comes to obesity

Health officials in Britain say Scotland now has the one of highest obesity rates in the developed world, and comes second to the United States.

Biologists link Huntington's disease to health benefits in young

For years researchers in neurology have believed that people with Huntington's disease have more children than the general population because of behavioral changes associated with the disease that lead to sexual promiscuity.

Stem-cell therapy opens new avenue of research against Huntington's disease

Paying close attention to how a canary learns a new song has helped scientists open a new avenue of research against Huntington's disease – a fatal disorder for which there is currently no cure or even a treatment to slow the disease.

Simulation reveals how body repairs balance after damage

Your body goes to a lot of trouble to make sure you stay upright. But when the brain's neural pathways are impaired through injury, age or illness, muscles are deprived of the detailed sensory information they need to perform the constant yet delicate balancing act required for normal movement and standing.

New nanoprobe imaging station helps study the distribution of elements in cells

Scientists suspect that iron accumulation plays a role in neurodegenerative processes such as Parkinson's disease, but its distribution in neurons has never been observed because of the lack of techniques to do so. Until today.

A blood test for concussions - aim of new research

The University of Rochester Medical Center received $1.5 million to develop a blood test for concussions by isolating proteins that can predict memory loss, chronic headaches or other neurological problems.

HPV is related to bladder cancer

The Human Papillomavirus (HPV) is considered the cause of one of the most important sexually transmitted diseases nowadays, and affects both men and women.

PET scans accurately detect a breast tumor's response to chemotherapy

Researchers in Australia have shown that positron emission tomography (PET) that uses a radioactive sugar molecule is more useful than mammography and ultrasound in predicting a breast tumour's response to chemotherapy and, therefore, the patient's ultimate likelihood of survival.

Aloe vera powder nose spray vaccine shows potential for bird flu treatment

Researchers at Texas A&M University are participating in developing a medicine that is worth sneezing about: a treatment for influenza that forms a jelly when sprayed into the nose.
