Factors associated with use of gastric cancer screening services in Korea

The mortality of gastric cancer is decreasing despite the increasing incidence in Korea. This can be explained by surgical technique development and early detection by endoscopic screening or upper gastrointestinal study.

Anti-psychotic drugs could help treat some major cancers

The observation that people taking medication for schizophrenia have lower cancer rates than other people has prompted new research revealing that anti-psychotic drugs could help treat some major cancers.

New understanding on basic cellular mechanisms responsible speech processing

Researchers from the Hebrew University of Jerusalem have succeeded for the first time in devising a model that describes and identifies a basic cellular mechanism that enables networks of neurons to efficiently decode speech in changing conditions.

Scientists take the first step to targeted treatment for stomach cancer

Researchers have identified a protein that plays an important role in the development of stomach cancers and that could one day be a target for new treatments for the disease, according to research published (Wednesday) in the British Journal of Cancer.

Alarming rise in oral cancer rates among forty-somethings

Rates of oral cancers, such as cancers of the mouth, tongue and lip, have increased by around a quarter in the past decade among people in their 40s, according to figures from Cancer Research UK.

Living cells controlled with light; potential for stem cell research

University of Central Florida researchers have shown for the first time that light energy can gently guide and change the orientation of living cells within lab cultures. That ability to optically steer cells could be a major step in harnessing the healing power of stem cells and guiding them to areas of the body that need help.

New biomarkers for Alzheimer's disease

A combination of proteins in the cerebrospinal fluid can reliably identify which patients with early symptoms of dementia will subsequently develop full-blown Alzheimer's disease, a research team at the University of Gothenburg, Sweden, has found in a major international study. The results were published in this week's edition of the Journal of the American Medical Association (JAMA).

Research on blood transfusions points to a potential risk of transfusing donated platelets

Doctors have noticed a pattern in performing bone marrow transplants as a cure for diseases involving bone marrow failure: more transfusions before a bone marrow transplant correlates with a higher likelihood of rejection, says James Zimring, MD, PhD, assistant professor of pathology and laboratory medicine at Emory University School of Medicine.

Many senior drivers unaware of potential impact on driving performance associated with taking medications

The findings, released today by the AAA Foundation for Traffic Safety, indicate that 95 percent of those age 55 and older have one or more medical conditions, 78 percent take one or more medications, and only 28 percent have an awareness of the risks those medications might have on driving ability.

Research looks at drop in delivery-related rate of death for infants born at term

During about the last 20 years, the risk of delivery-related death at birth or shortly thereafter for term infants has decreased nearly 40 percent in Scotland, with the largest contributing factor being a decrease in the number of deaths caused by a lack of oxygen for the baby during the childbirth process, according to a study in the August 12 issue of JAMA.

Research shows how long-lasting memories form in the brain

A new study by researchers at Wake Forest University School of Medicine may reveal how long-lasting memories form in the brain.

Oxygen treatment may speed memory loss associated with Alzheimer's

A 65-year-old women goes into the hospital for routine hip surgery. Six months later, she develops memory loss and is later diagnosed with Alzheimer's Disease. Just a coincidence? Researchers at the University of South Florida and Vanderbilt University don't think so. They suspect that the culprit precipitating Alzheimer's disease in the elderly women may be a routine administration of high concentrations of oxygen for several hours during, or following, surgery - a hypothesis borne out in a recent animal model study.

An examination of the social impact of armed conflict and militarization

New research out of the University of Cincinnati is a rare examination of the social impact of armed conflict and militarization. Steve Carlton-Ford, a UC associate professor of sociology, presented the findings Aug. 11 at the 104th annual meeting of the American Sociological Association (ASA) in San Francisco.

Potential new treatment for drug resistant brain tumors

Dr. Karen Newell, Ph. D., the lead researcher for bio technology company Viral Genetics (Pink Sheets: VRAL), will address the 4th Annual Aspen Symposium on Brain Tumor Immuno- and Stem Cell Therapy. Her presentation will highlight the potential for combining chemotherapy with compounds that interfere with the ability of brain tumor cells to generate the energy needed to repair chemotherapy induced DNA damage.

Alcoholics display abnormal brain activity when processing facial expressions

Researchers from Boston University School of Medicine (BUSM) have found that individuals who have a long history of alcoholism, but who have been abstinent for at least a month up to many years, showed abnormal brain activity when looking at facial expressions of others.

Education impacts cognitive function in Alzheimer's disease

Researchers at the Department of Psychiatry, Klinikum rechts der Isar, Technische Universität München, investigated the effects of formal education on the symptoms of Alzheimer's disease. They were able to show that education diminishes the impact of Alzheimer's disease on cognition even if a manifest brain volume loss has already occurred.

New treatment for oxygen-starved newborns

Until now immediate cooling of the newborn infant was the only treatment that could possibly prevent brain damage following oxygen deprivation during delivery. New research findings from the Sahlgrenska Academy at the University of Gothenburg and Sahlgrenska University Hospital, Sweden, in collaboration with Zhengzhou University in China, open up the possibility of a new and effective treatment that can be started as late as two days after birth.

Retrovirox receives another NIH grant for novel inhibitors of HIV entry

RetroVirox, Inc., a biotechnology company specializing in the development of novel antivirals, announced today that it has received a grant award of $296,875 from the National Institute of Allergy and Infectious Disease (NIAID), of the National Institutes of Health (NIH). This is the second award to RetroVirox from the NIH in less than six months. In March 2009 the company received its first grant to develop novel inhibitors of HIV entry.

New tool for virtual surgery simulates blood flow - helps plan child's delicate heart surgery

Researchers at the Georgia Institute of Technology, collaborating with pediatric cardiologists and surgeons at The Children's Hospital of Philadelphia, have developed a tool for virtual surgery that allows heart surgeons to view the predicted effects of different surgical approaches. By manipulating three-dimensional cardiac magnetic resonance images of a patient's specific anatomy, physicians can compare how alternative approaches affect blood flow and expected outcomes, and can select the best approach for each patient before entering the operating room.

Aspirin improves survival after colorectal cancer diagnosis

Men and women who were diagnosed with colorectal cancer and began regular use of aspirin had a lower risk of overall and colorectal cancer death compared to patients not using aspirin, according to a study in the August 12 issue of JAMA.
