Trying to control pain can be a double-edged sword, say scientists

...ey found that whilst the subjects' outlook did not affect the anterolateral prefrontal cortex when they controlled the stimulus, when they were not able to stop the painful stimulation subjects with no control expectations were better at activating this brain region than those with a strong control belief. ...

Men with prostate cancer avoid radiation due to misconceptions

...s related to false beliefs on how the X-rays would affect them. For example, some patients think that radiation cannot be controlled because it is invisible, that it will harm surrounding unprotected organs and that it is dangerous for family members to physically be near them when undergoing radiation trea...

With fruit fly sex, researchers find mind-body connection

...and doublesex act together, as a switch system, to affect this sexual behavior. "The big story is the crossover between the 'mind' and 'body' pathways," McKeown said. "If sexual behaviors are genetically controlled in humans, I expect that this system would be just as much, if not more, complicated." ...

German researchers develop first non-invasive test to measure skin aging

...could become useful in studying skin diseases that affect the collagen structure. Those include scleroderma, a poorly understood disease characterized by excessive deposits of collagen in the skin, and some chronic complications of graft-versus-host disease, which occur when the tissues of bone marrow trans...

Increase in drug development for killer diseases is not enough

...his is despite the fact that these diseases mainly affect the poor in developing countries and development of treatments is inhibitive due to lack of economic demand. Researchers argue that the rate of development of drugs (and of some vaccines and diagnostics) would increase if more incentives were created...

Gene linked with mental illness shapes brain region, researchers find

...ther the person had a psychiatric disorder did not affect the size of the pulvinar. Dr. German cautioned, however, that the entire brain is not simply larger in individuals carrying two copies of the SERT-s gene. Similar studies in other areas of the brain have found that the SERT-s gene is associated wi...

Genome archaeology illuminates the genetic engineering debate

...nome and have likely undergone changes in how they affect biological operations. "The research, conducted by an international collaboration of scientists, will help scientists and farmers improve these significant crops and gain new and important insights in the evolution of the grass species in general,"...

How mammals fuel milk production may have implications for cancer

... normal pathways of breast development undoubtedly affect breast cancer, the findings may have therapeutic implications, the researchers said. The researchers found that one of three “isoforms?of the gene known as Akt is specifically required for lactating mice to synthesize sufficient quantities of milk t...

Fast-freeze snapshot yields new picture of nerve-muscle junction

...ore precise understanding of how synaptic proteins affect release of neurotransmitter chemicals at the junctions -- the signal that enables nerve cells to issue commands. The technique described in the new study, high-pressure freeze electron microscopy and immuno-gold staining, now provides an accurate pi...

What does the public really know about HPV?

...arch assessed how its portrayal in the media would affect attitudes toward vaccination among women. The study was a part of the Annenberg National Health Communication Survey, a monthly barometer of the public's health communication practices and needs. The survey is jointly funded by the National Can...

Ocean seep mollusks may share evolutionary history with other deep-sea creatures

... sediment runoff--all sorts of factors which don't affect animals in the deep sea," Little explained. This makes it difficult to tell whether seep mollusks owe their long evolutionary history to their unique home environment or to their status as deep-sea creatures, he noted. Cold seeps are places where f...

Two studies on bee evolution reveal surprises

...ch family is the most primitive. Bees are known to affect plant evolution by spreading pollen and preferring to pollinate some types of plants over others. Because scientists assume that bees have essentially always been around, pollinating plants and "creating" new species, it has been a mystery why the be...

Scientists explore how complex organs develop from a simple bud

...e growth and development of fetal stage organs can affect organ function after birth -- have important implications for human health. Two of the reviews in the Journal delve into tubulogenesis ?a process that is intimately tied to branching morphogenesis. Another contains research aimed at helping patient...

Inheritance outside DNA

... the loss of IGF2 imprinting seems to particularly affect the behavior of the adult stem cells that continually regenerate the colon in mice. This probably plays a role in the increased risk of colon cancer, says Feinberg. Spotting epigenetic markers like lost IGF2 in humans could be used in future cance...

Seals protect brain, conserve oxygen by turning off shivering response on icy dives

...ypoxia is important because they are problems that affect people under a variety of circumstances. Doctors often are called upon to treat people who have suffered accidental hypothermia, for example, as a result of falling into the ocean or becoming lost during the winter. In addition, several hundred thous...

T for two: Scientists show how immune system chooses best way to fight infection

... new treatments could be developed to deliberately affect the type of T cells produced, allowing scientists to tackle a number of diseases which are influenced by these different types of T cells. "Our team has shown that a process known as 'trans-conditioning', which we knew to be involved in T cell dev...
