A tipple a day helps seniors keep disabilities at bay

It is well known that moderate drinking can have positive health benefits - for instance, a couple of glasses of red wine a day can be good for the heart.

Lack of grey matter linked to schizophrenia and bipolar disorder

A research study led by scientists from the Gregorio Marañón University Hospital in Madrid and the Network of Centres for Biomedical Research in Mental Health Networks (CIBERSAM) shows that adolescents experiencing a first outbreak of psychosis have lower levels of grey matter in their brains than healthy teenagers. Strangely, this change was seen in patients suffering from various psychoses, including bipolar illness and schizophrenia.

How the sensory organs of bacteria function

Bacteria can occur almost anywhere on earth and exist under the most varying conditions. If these tiny, microscopic organisms are to survive in these environments, they need to be able to rapidly detect changes in their surroundings and react to them.

E. coli persists against antibiotics through HipA-induced dormancy

Bacteria hunker down and survive antibiotic attack when a protein flips a chemical switch that throws them into a dormant state until treatment abates, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan.16 edition of Science.

DREAM gene found to be a genetic candidate for explaining old age dementia

In 2002, a group of scientists at the University of Toronto was able to identify a gene which they dubbed DREAM (downstream regulatory element antagonistic modulator).

Genetic variations in DNA repair patterns may increase risk of pancreatic cancer

Genetic variations in DNA repair patterns may increase risk of pancreatic cancer by as much as threefold or decrease it by as much as 77 percent, depending on the genes involved, according to a report published in the January 15, 2009, issue of Clinical Cancer Research, a journal of the American Association for Cancer Research.

Depressed adolescents not harmed by being part of placebo group in clinical trial

In a national clinical trial, adolescents with moderate to severe depression first given a placebo treatment and then an antidepressant medication alone or in combination with therapy responded just as well over the long term as participants who received active treatment throughout the study, UT Southwestern Medical Center researchers report.

Tax on alcohol has a clear effect on drinking

With many local and national governments currently debating proposals to raise alcohol taxes, a timely new study published online in the February edition of Addiction journal finds that the more alcoholic beverages cost, the less likely people are to drink.

Defects in critical DNA repair genes may predict pancreatic cancer risk

Abnormalities in genes that repair mistakes in DNA replication may help identify people who are at high risk of developing pancreatic cancer, a research team from The University of Texas M. D. Anderson Cancer Center reports in the Jan. 15 issue of Clinical Cancer Research .

New approach to treat advanced melanoma

Skin cancer patient Debra Gardocki receives an injection from oncologist Dr. Sanjiv Agarwala as part of a study exploring a new approach to treat advanced melanoma -- an often fatal form of cancer for which there are limited effective treatment options.

Nanotubes sniff out cancer agents in living cells

A multidisciplinary team at the Massachusetts Institute of Technology (MIT) has developed carbon nanotubes that can be used as sensors for cancer drugs and other DNA-damaging agents inside living cells. The sensors, made of carbon nanotubes wrapped in DNA, can detect chemotherapy drugs such as cisplatin as well as environmental toxins and free radicals that damage DNA.

Too much coffee can lead to hallucinations

According to a study by researchers at Durham University people with a higher caffeine intake, from coffee, tea and caffeinated energy drinks, are more likely to experience hallucinatory experiences such as hearing voices and seeing things that are not there.

Telephone support after traffic accidents reduces problems and improves quality of life

People who were injured in road accidents had fewer problems and a much higher quality of life if they received a simple follow-up call from a nurse three weeks after being discharged from hospital, according to research in the January issue of the Journal of Clinical Nursing.

Study shows surgery provides good long-term outcomes for patients with gastrointestinal cancers

New research published in the January issue of the Journal of the American College of Surgeons shows that laparoscopic removal of gastrointestinal stromal tumors (GISTs) is safe and effective, with a disease-free survival rate of nearly 80 percent after an average follow-up time of three and a-half years.

Study shows how defective DNA repair triggers 2 neurological diseases

Scientists at St. Jude Children's Research Hospital have teased apart the biological details distinguishing two related neurological diseases-ataxia telangiectasia-like disease (ATLD) and Nijmegen breakage syndrome (NBS).

Odors can alter gene expression in an olfactory neuron

New research from University of California, Davis, shows why a species of tiny worm can learn to ignore an odor – information that could have implications for how human memories are formed.

Study examines live birth rates following IVF

Thirty years ago last summer, the world's first "test-tube" baby was born, and since then more than 1 million infants have been successfully conceived through in vitro fertilization (IVF), the technique in which a woman's eggs and man's sperm are fertilized in a laboratory and then implanted in the mother's womb.

Stem cells could be used for personalized cancer treatment

Using cancer cells from an ovarian cancer patient and human embryonic stem cells, Israeli researchers have created a cancerous tumor in a mouse that mimics the way the tumor would develop in the patient's body.

Domain duplication, divergence, and loss events in vertebrate Msx paralogs reveal phylogenomically informed disease markers

The work of Forsyth scientist Peter Jezewski, DDS, Ph.D., has revealed that duplication and diversification of protein regions ('modules') within ancient master control genes is key to the understanding of certain birth disorders.
