Death rates decline for advanced heart failure patients, but outcomes are still not ideal
UCLA researchers examining outcomes for advanced heart-failure patients over the past two decades have found that, coinciding with the increased availability and use of new therapies, overall mortality has decreased and sudden cardiac death, caused by the rapid onset of severe abnormal heart rhythms, has declined. However, the team found that even today, with these significant improvements, one-third of patients don't survive more than three years after being diagnosed with advanced disease.

UCI study reveals new mechanism for estrogen suppression of liver lipid synthesis
By discovering the new mechanism by which estrogen suppresses lipid synthesis in the liver, UC Irvine endocrinologists have revealed a potential new approach toward treating certain liver diseases. With this finding, Dr. Ellis Levin and colleagues believe they are changing long-held views in the field.

Researchers find common childhood asthma unconnected to allergens or inflammation
Little is known about why asthma develops, how it constricts the airway or why response to treatments varies between patients. Now, a team of researchers at Weill Cornell Medical College, Columbia University Medical Center and SUNY Downstate Medical Center has revealed the roots of a common type of childhood asthma, showing that it is very different from other asthma cases.

Regenerating spinal cord fibers may be treatment for stroke-related disabilities
A study by researchers at Henry Ford Hospital found "substantial evidence" that a regenerative process involving damaged nerve fibers in the spinal cord could hold the key to better functional recovery by most stroke victims. The findings may offer new hope to those who suffer stroke, the leading cause of long-term disability in adults.

Drug reverses Alzheimer's disease deficits in mice, Pitt research confirms
An anti-cancer drug reverses memory deficits in an Alzheimer's disease mouse model, University of Pittsburgh Graduate School of Public Health researchers confirm in the journal Science. The research, funded by the National Institutes of Health's National Institute on Aging and Alzheimer's Association, reviewed previously published findings on the drug bexarotene, approved by the US Food and Drug Administration for use in cutaneous T cell lymphoma.

Motion quotient
A brief visual task can predict IQ, according to a new study. This surprisingly simple exercise measures the brain's unconscious ability to filter out visual movement. The study shows that individuals whose brains are better at automatically suppressing background motion perform better on standard measures of intelligence.

Study shows people can be trained to be more compassionate
Until now, little was scientifically known about the human potential to cultivate compassion -- the emotional state of caring for people who are suffering in a way that motivates altruistic behavior. A new study by researchers at the Center for Investigating Healthy Minds at the Waisman Center of the University of Wisconsin–Madison shows that adults can be trained to be more compassionate.

The report, published Psychological Science, a journal of the Association for Psychological Science, investigates whether training adults in compassion can result in greater altruistic behavior and related changes in neural systems underlying compassion.

Research offers promising new approach to treatment of lung cancer
Researchers have developed a new drug delivery system that allows inhalation of chemotherapeutic drugs to help treat lung cancer, and in laboratory and animal tests it appears to reduce the systemic damage done to other organs while significantly improving the treatment of lung tumors -- the tumors virtually disappeared.

Researchers eliminate schizophrenia symptoms in an animal model
Overexpression of a gene associated with schizophrenia causes classic symptoms of the disorder that are reversed when gene expression returns to normal, scientists report. They genetically engineered mice so they could turn up levels of neuregulin-1 to mimic high levels found in some patients then return levels to normal, said Dr. Lin Mei, Director of the Institute of Molecular Medicine and Genetics at the Medical College of Georgia at Georgia Regents University.

Penn study shows how immune system peacefully co-exists with 'good' bacteria
The human gut is loaded with helpful bacteria microbes, yet the immune system seemingly turns a blind eye. Now, researchers know how this friendly truce is kept intact. Innate lymphoid cells directly limit the response by inflammatory T cells to commensal bacteria in the gut of mice. Loss of this ILC function effectively puts the immune system on an extended war footing against the commensal bacteria a condition observed in multiple chronic inflammatory diseases.

Scientists uncover molecular roots of cocaine addiction in the brain
Researchers at Johns Hopkins have unraveled the molecular foundations of cocaine's effects on the brain, and identified a compound that blocks cravings for the drug in cocaine-addicted mice. The compound, already proven safe for humans, is undergoing further animal testing in preparation for possible clinical trials in cocaine addicts, the researchers say.

Changing cancer's environment to halt its spread
By studying the roles two proteins, thrombospondin-1 and prosaposin, play in discouraging cancer metastasis, a trans-Atlantic research team has identified a five-amino acid fragment of prosaposin that significantly reduces metastatic spread in mouse models of prostate, breast and lung cancer. The findings suggest that a prosaposin-based drug could potentially block metastasis in a variety of cancers.

Keeping stem cells strong
A team of researchers led by biologists at the California Institute of Technology has found that, in mouse models, the molecule microRNA-146a acts as a critical regulator and protector of blood-forming stem cells (called hematopoietic stem cells, or HSCs) during chronic inflammation, suggesting that a deficiency of miR-146a may be one important cause of blood cancers and bone marrow failure.
