Psychological pain of Holocaust still haunts survivors

2010-09-20
WASHINGTON – Holocaust survivors show remarkable resilience in their day-to-day lives, but they still manifest the pain of their traumatic past in the form of various psychiatric symptoms, according to an analysis of 44 years of global psychological research. Jewish Holocaust survivors living in Israel also have higher psychological well-being than those who live in other countries, which suggests living in that country could serve as a protective factor, according to researchers in Israel and the Netherlands. Their findings are reported in Psychological Bulletin, which ...

Climate change: Can geoengineering satisfy everyone?

2010-09-20
Reflecting sunlight from the Earth by geoengineering would undoubtedly cool the climate, but would different countries agree on how much to reflect? Research by climate scientists at the University of Bristol shows that the impact of geoengineering would be felt in very different ways across the world. Previous studies of geoengineering approaches, aimed at averting dangerous climate change, have shown that although the average global temperature could be restored to 'normal' levels, some regions would remain too warm, whereas others would 'overshoot' and cool to much. ...

Compound boosts marijuana-like chemical in the body to relieve pain at injury site

2010-09-20
Irvine, Calif., Sept. 20, 2010 — American and Italian researchers have found that a novel drug allows anandamide – a marijuana-like chemical in the body – to effectively control pain at the site of an injury. Led by Daniele Piomelli, the Louise Turner Arnold Chair in Neurosciences and director of the Center for Drug Discovery at UC Irvine, the study suggests that such compounds could form the basis of pain medications that don't produce sedation, addiction or other central nervous system side effects common with existing painkillers, such as opiates. "These findings ...

Scientists show Six3 gene essential for retinal development

2010-09-20
New research led by St. Jude Children's Research Hospital investigators adds to evidence that the Six3 gene functions like a doorman in the developing brain and visual system, safeguarding the future retina by keeping the region where the eye is forming free of a signaling protein capable of disrupting the process. The findings underscore the pivotal role Six3 plays in the developing nervous system as a key regulator of the Wnt family of signaling proteins and expands on earlier work from the laboratory of Guillermo Oliver, Ph.D., member of the St. Jude Department of ...

Millions with voice problems don't know treatment available

2010-09-20
DURHAM, N.C.—Two-thirds of Americans with voice problems don't seek medical care either because they don't know treatment is available or because they think the problem will just go away, according to a new study conducted at the Duke Voice Care Center. That's concerning, says Seth Cohen, MD, an otolaryngologist at Duke. "Voice disorders aren't benign nuisances that just go away. They are symptoms of a range of medical conditions from allergies to cancer. When caught early, the right treatment can make a big difference. Left untreated, they can become chronic problems ...

New pathway regulates immune balance and offers promising drug development target

2010-09-20
St. Jude Children's Research Hospital scientists have identified a new pathway that helps control the immune balance through reciprocal regulation of specialized T lymphocytes, which play very different inflammatory roles. Investigators also determined that two drugs working in different ways to dampen the inflammatory response in patients with multiple sclerosis or following organ transplantation target this new mechanism. Further research into the pathway might lead to new medications to block other autoimmune disorders or to new anti-rejection drugs, researchers said. ...

A drug commonly used for the treatment of chronic obstructive pulmonary disease (COPD) successfully treats adults whose asthma is not well-controlled on low doses of inhaled corticosteroids, reported researchers supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. "This study's results show that tiotropium bromide might provide an alternative to other asthma treatments, expanding options available to patients for controlling their asthma," said NHLBI Acting Director Susan B. Shurin, M.D. "The goal in managing ...

Biologists discover biochemical link between biological clock and diabetes

2010-09-20
Biologists have found that a key protein that regulates the biological clocks of mammals also regulates glucose production in the liver and that altering the levels of this protein can improve the health of diabetic mice. Their discovery, detailed in this week's advanced online publication of the journal Nature Medicine, provides an entirely new biochemical approach for scientists to develop treatments for obesity and type 2 diabetes. It also raises the interesting possibility that some of the rise in diabetes in the U.S. and other major industrialized countries could ...

Rutgers researchers discover how HIV resists AZT

2010-09-20
NEW BRUNSWICK, N.J. – Rutgers researchers have discovered how HIV-1, the virus that causes AIDS, resists AZT, a drug widely used to treat AIDS. The scientists, who report their findings in Nature Structural & Molecular Biology, believe their discovery helps researchers understand how important anti-AIDS treatments can fail and could help AIDS researchers develop more effective treatment for the disease. "What we've found is the detailed way in which the mutations act to promote the resistance," said author Eddy Arnold, Board of Governors Professor of Chemistry and ...
