Welcome to another edition of ScienceDaily's newsletter.Mechanism that may trigger degenerative disease identified (June 26, 2010) -- A mechanism that regulates stem-cell differentiation in mice testes suggests a similar process that may trigger degenerative disease in humans, according to a reproductive physiologist. ... > full story
Chemists find an easier way to synthesize new drug candidates; New method could have a big impact on pharmaceutical business (June 26, 2010) -- Chemists have designed a new way to attach a trifluoromethyl group to certain compounds, which they believe could allow pharmaceutical companies to create and test new drugs much faster and potentially reduce the cost of drug discovery. The new synthesis could have an immediate impact. ... > full storyNovel radiotracer shines new light on the brains of Alzheimer's disease patients (June 26, 2010) -- A trial of a novel radioactive compound readily and safely distinguished the brains of Alzheimer's disease patients from healthy volunteers on brain scans and opens the doors to making such imaging available beyond facilities that can manufacture their own radioactive compounds. ... > full story
Scientists create 3-D models of whole mouse organs (June 26, 2010) -- Engineers have for the first time created 3-D models of whole intact mouse organs, a feat they accomplished using fluorescence microscopy. ... > full story
Ingredient in red wine may prevent some blinding diseases (June 26, 2010) -- Resveratrol -- found in red wine, grapes, blueberries, peanuts and other plants -- stops out-of-control blood vessel growth in the eye, according to vision researchers. The discovery has implications for preserving vision in blinding eye diseases such as diabetic retinopathy and age-related macular degeneration, the leading cause of blindness in Americans over 50. ... > full story
Gene therapy a step closer to mass production (June 26, 2010) -- Researchers in Latvia and Finland have synthesized and studied a range of organic compounds able to carry genetic material into individual cells where it can remedy the diseases caused by defective genes. Still under development, these compounds are much more readily produced than the viral carriers now in use and avoid their side-effects. Most importantly, they are much more effective than other organic carrier substances developed so far. ... > full storyDetecting eye injury (June 26, 2010) -- Scientists have developed a noninvasive imaging technique to detect early stages of eye disease. ... > full story
Study identifies couples’ underlying concerns during a fight (June 26, 2010) -- A new study has found that there are two fundamental underlying concerns when partners in a committed relationship fight. Researchers have identified the first type of underlying concern as perceived threat, which involves a perception that one's partner is being hostile, critical, blaming or controlling. The second type of concern is called perceived neglect, which involves a perception that one's partner is failing to make a desired contribution or failing to demonstrate an ideal level of commitment or investment in the relationship. ... > full storyVirus works with gene to cause Crohn's-like illness (June 25, 2010) -- Scientists have shown that a specific virus can interact with a mutation in the host's genes to trigger disease. The observation may help explain why many people with disease risk genes do not actually develop disease. ... > full story
Silencing hepatitis B virus prevents recurrence of liver cancer (June 25, 2010) -- Previous studies have shown that antiviral treatment reduces the incidence of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. But now, researchers are reporting that the antiviral therapy also prevents recurrence of HCC and extends patients' lives. ... > full story
Tactile sensations influence social judgments and decisions (June 25, 2010) -- Psychologists report that interpersonal interactions can be shaped, profoundly yet unconsciously, by the physical attributes of incidental objects: Resumes reviewed on a heavy clipboard are judged to be more substantive, while a negotiator seated in a soft chair is less likely to drive a hard bargain. The work suggests physical touch -- the first of our senses to develop -- may continue throughout life as a scaffold upon which we build our social judgments and decisions. ... > full story
More variation in human genome than expected: Surprisingly common transposons or 'jumping genes' are known to cause disease (June 25, 2010) -- Scientists are finding more variation in the human genome than they had expected, according to new research. The study is one of the first to take an in-depth look at transposons, segments of DNA that can replicate themselves and move to new sites in each individual's genome. The researchers found that new occurrences of transposons were surprisingly prevalent in human and in lung cancer genomes. ... > full storyCopyright 1995-2010 © ScienceDaily LLC. All rights reserved.
