Hybrid molecule causes cancer cells to self-destruct

...athkumar and his colleagues built upon 20-year-old findings that a short-chain fatty acid called butyrate can slow the spread of cancer cells. In the 1980s, researchers discovered that butyrate, which is formed naturally at high levels in the digestive system by symbiotic bacteria that feed on fiber, can rest...

Gene variations contribute to aggression and anger in women

... at the University of Pittsburgh, will present the findings today at the American Psychosomatic Society's Annu...ests for anger, hostility and aggression. These findings may aid in establishing a potential marker for certain conditions associated with aggression and ang...

Lithium builds gray matter in bipolar brains, UCLA study shows

...he standard treatment for some 50 years. These new findings suggest that lithium may work by increasing the amount of gray matter in particular brain areas, which in turn suggests that existing gray matter in these regions of bipolar brains may be underused or dysfunctional. This is the first time researc...

3 proteins may play important role in nerve-cell repair

...eight times faster than in control cells. "Our findings suggest that these three proteins could be importa...ve cells cannot regenerate damaged axons. "Our findings provide additional evidence that cAMP plays an important role in axon growth and suggest that these ...

Stem cells act through multiple mechanisms to benefit mice with neurodegenerative disease

...ment - which collaborate to benefit disease. These findings also raise the possibility - somewhat counter-intu... of diseases called "neurogenetic diseases". These findings contribute fundamental basic knowledge about stem cell biology that will help inform medical scienti...

Scientists find hormone activity explains adolescent mood swings

...rmacology at SUNY Downstate Medical Center, report findings demonstrating that a hormone normally released in response to stress, THP, actually reverses its effect at puberty, when it increases anxiety. This hormone normally acts like a tranquilizer, acting at sites in the brain that "calm" brain activity....

A genetic 'gang of 4' drives spread of breast cancer

...orial Sloan-Kettering Cancer Center, published its findings in articles in the April 12, 2007, issue of the jo... penetrate the lung tissue to grow there. "These findings provide a beautiful explanation for how the genes that we identified in breast cancer patients as be...

Newborn brains grow vision and movement regions first

...percent larger than the right side. While these findings are intriguing, Gilmore said, they just scratch the surface of an area that has been little studied so far and in which much more research needs to be done. "This study gives us the first glimpse that there are regional differences in how quickly t...

Research finds music training 'tunes' human auditory system

...ed not only in music but also in language. The findings indicate that experience with music at a young age...Laboratory and senior author of the study. "Our findings underscore the pervasive impact of musical training on neurological development. Yet music classes a...

Fitness has fallen since the days of Ancient Greece

...cientist today (February 8). By comparing these findings to classical texts that record details of their endurance, he realised that the rowers of ancient Athens -- around 500BC -- would had to have been highly elite athletes, even by modern day standards. Says Dr Rossiter: "Ancient Athens had up to 200...

Cold sore virus might play role in Alzheimer's disease

...ricans and causes cold sores around the mouth. The findings from a group at the University of Rochester Medical Center show that the particular form of the gene that puts people at risk also creates a fertile environment for herpes in the brain, allowing the virus to be more active than other forms of the Apo...

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex

...s at North Carolina State University, report their findings in the April 13 Science. "Most people believe that birds evolved from dinosaurs, but that’s all based on the architecture of the bones," said John Asara, director of the mass spectrometry core facility at Beth Israel Deaconess Medical School and HMS...

Genetic pathways to curable and incurable forms of pancreatic cancer identified

...he United States, arise from cystic tumors. The findings reported in the journal by Hingorani and colleagues represent an accidental discovery. The researchers started out studying the common genetic pathways to pancreatic ductal adenocarcinoma in hopes of finding clues to developing early detection biomar...

Robotic therapy helps restore hand use after stroke

...y aid hand function. Cramer presented HOWARD study findings yesterday at the American Stroke Association's International Stroke Conference 2007 in San Francisco. Developed by UCI researchers, HOWARD aids patients as they grasp and release common objects. The robotic device wraps around the hand and couple...

Bacteria control how infectious they become, study finds

...iate in microbiology at Ohio State University. The findings appear in the April 13 issue of the journal Molecular Cell. Gene expression ?the process of turning on, or activating, genes ?is controlled by proteins called transcription factors. Every type of bacteria known to humankind contains the transcript...

Liver regeneration may be simpler than previously thought

... the developing and regenerating livers. These findings showed that a regenerating liver does not behave as a developing embryo. Instead, regeneration could actually be only due to an increase in cells that multiply through regular cell divisions, a process called hyperplasia. The new results may also...

Wired for sound: How the brain senses visual illusions

...cortical areas." "This is part of a set of new findings by scientists in the field that show how integration of multiple sensations can happen much more rapidly than we thought before," said Mishra. "We show physiological evidence that visual and auditory stimulation might not be processed separately, th...

New protein inhibitor impedes growth of cancerous cells

...e and cancer-derived cells growing in culture. The findings are reported in companion papers reported by two collaborating groups—one (Lenart et al.) led by Jan-Michael Peters of the Research Institute of Molecular Pathology in Vienna, and the other (Steegmaier et al.) led by Norbert Kraut of Boehringer Ingel...

Microbes start immune response by sneaking inside cells

..., University of Michigan scientists describe their findings that bacteria can barge inside these guard cells and independently initiate a powerful immune response. The study, published online ahead of print in the April issue of the journal Immunity and accompanied by a special commentary, adds important ne...

Angelman syndrome deficits rescued in mice

...deficits in mice to humans, Weeber thinks that the findings may point to new therapeutic targets for the disorder. "It's very conceivable that if we can figure out what lies between UBE3A and CaMKII ?and if it's a specific path ?then that could be a therapeutic target." But the results may apply more br...
