Whole-body positron emission tomography/computed tomography scans may help physicians identify malignant cancerous tumors

A team of researchers at Johns Hopkins Medical Institutions in Baltimore, Md., reports that whole-body positron emission tomography/computed tomography (PET/CT) scans may help physicians identify new, unexpected malignant cancerous tumors in patients, according to an article in the May issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Adolescent depression can be as high as 20 percent

Teenage depression is widespread and can become a life-long illness, but is more often transitory, said UCLA Psychology Professor Constance Hammen, who discussed her research at the American Psychological Society's annual convention in Los Angeles.

Discovery may lead to therapies to treat the neurological disease

Opening a window to understand the molecular basis of a hereditary ataxia, Dartmouth Medical School researchers have identified an enzyme activity that is inactivated in all reported mutant forms of a disease protein. The discovery may lead to therapies to treat the neurological disease.

A new technique might allow women diagnosed with cancer the opportunity to have children when chemotherapy and radiation treatments rob them of their fertility

Freezing eggs is one thing; thawing them safely so they can lead to pregnancy is the challenge. In the past, efforts to freeze a woman's eggs, or oocytes, have not worked well because the cells are large. When the egg is thawed, ice crystals cause damage that prevents the egg from being fertilized.

One in five patients hospitalized for heart attack experiences a major depression

According to the Hopkins cardiologists who conducted the study, these depressed patients are 50 percent more likely than other heart attack patients to need hospital care for a heart problem again within a year and three times as likely to die from a future attack or other heart-related conditions.

How the human brain can learn without thinking

Watch out -- you may learn something and not even know it, says Takeo Watanabe, an associate professor of psychology at Boston University's Center for Brain and Memory. Watanabe and his team recently pinpointed the mechanism that makes subliminal learning work. Watanabe will present the team's findings at the American Psychological Society meeting in Los Angeles, May 27 and 28.

Long-lasting depression more common among blacks and Mexican American

While depression seems much more common among whites than blacks or Mexican Americans, the opposite is true when it comes to a milder mood disorder known as dysthemia.

Is winter flu worse because of exercise-induced 'window of susceptibility'?

When you exercise or work outside in winter, that dry feeling at the back of your throat indicates the cold air has irritated your throat. Racehorses share a similar experience: exercising in below-freezing air causes mild airway injury.

U.S. House of Representatives approve two bills on stem-cell research

Two new bills related to stem-cell research have been approved by the U.S. House of Representatives one promoting non-destructive methods and the other supporting research resulting in the death of unborn children.

'Bad' metabolism cloggs up arteries

Scientists are now saying that a 'bad' metabolism may explain why some people who have never smoked and do not have high cholesterol levels suffer from a potentially lethal build-up of plaque in the arteries.

Researchers discover way to reduce plaque deposits on the brain that could slow the progression of Alzheimer's disease

Their findings, which will be highlighted at the upcoming 2005 American Association of Pharmaceutical Scientists' (AAPS) National Biotechnology Conference in San Francisco, brings renewed hope to the 4.5 million Americans who have Alzheimer's disease.

Direct link between inefficient metabolism and atherosclerosis

An experiment that turned out very differently than expected led scientists at Washington University School of Medicine in St. Louis to the first direct link between inefficient metabolism and atherosclerosis.

Increase in heart surgery mortality from SSRIs or depression?

Duke University Medical Center researchers have found that patients who were using a class of anti-depression drugs known as selective serotonin reuptake inhibitors (SSRI) prior to undergoing coronary artery bypass surgery have significantly higher death and rehospitalization rates up to five years after the procedure than patients who were not on SSRIs.

Research provides roadmap for the development of human therapies for cytomegalovirus (CMV)

McGill University Health Centre (MUHC) researchers have defined genetic resistance to the widespread virus, cytomegalovirus (CMV)--a member of the viral group that causes some of the world's most prevalent diseases, such as herpes, chicken pox and mononucleosis.

Tobacco use persists after liver transplant for alcoholic liver disease

Alcohol and tobacco often go hand-in-hand. Studies have shown that approximately 90 percent of problem drinkers also smoke or chew tobacco. But tobacco use is not adequately addressed when patients undergo liver transplantation due to alcoholic liver disease, say authors of a new report.

HIPAA privacy rule makes it harder, costlier to do research that improves the quality of medical care

New research reveals a clash between two of the biggest issues in health care today: protecting individual patients' privacy and improving the quality, safety and cost of medical care for all patients.

Researchers pinpoint circuit in the brain responsible for encoding decision-making

Researchers at The Johns Hopkins University have pinpointed a circuit in the brain responsible for encoding decision-making behavior, a circuit that - if damaged - appears to prevent a person from altering that behavior when circumstances change.

Most serious side effects in statins may be higher in one of the newest drugs, rosuvastatin (Crestor)

A post-market analysis of cholesterol-lowering drugs called statins indicates that some of the most serious side effects may be higher in one of the newest drugs, rosuvastatin (Crestor). The drug is the strongest statin available because it has the greatest effect per milligram on low-density lipoprotein ("bad" cholesterol).

'Brown fat cells' hold clues for possible obesity treatments

Joslin Diabetes Center scientists have discovered a group of genes that govern the genesis of calorie-burning fat cells. This discovery may lead to novel ways to treat obesity in humans.

Researchers have succeeded in mapping the unique patterns of neural activity produced by a wide range of odors

Revealing these distinct - but often overlapping - patterns of neural activity represents a significant step in understanding how the brain translates complex signals from odorant receptors in the nose into odor perception in the brain, the researchers said.
