Researchers at the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, identified for the first time the key role specific microRNAs (miRNAs) play in melanoma metastasis to simultaneously cause cancer cells to invade and immunosuppress the human body's ability to fight abnormal cells. The new study is published in the July 11, 2011 issue of the journal Cancer Cell. Researchers performed a miRNA analysis of human melanoma tissues, including primary and metastatic tumors. They found in both sets of tumor cells significantly high levels ...

Researchers from Rigshospitalet – Copenhagen University Hospital – and the University of Copenhagen have discovered why malaria parasites are able to hide from the immune defences of expectant mothers, allowing the parasite to attack the placenta. The discovery is an important part of the efforts researchers are making to understand this frequently fatal disease and to develop a vaccine. Staff member at CMP. Photo: Lars Hviid"We have found one likely explanation for the length of time it takes for the expectant mother's immune defences to discover the infection in the ...

PITTSBURGH, July 11 – A new method for scoring the severity of illness for patients after cardiac arrest may help to predict their outcomes, according to researchers at the University of Pittsburgh School of Medicine. Most importantly, their findings, published in the early online version of Resuscitation, also show that none of the severity categories rules out the potential for a patient's recovery. "Traditionally, we have used historical or event-related information, such as initial cardiac rhythm or whether someone witnessed the collapse, to categorize these patients ...

Rockville, Md. — Using owls as a model, a new research study reveals the advantage of stereopsis, commonly referred to as stereovision, is its ability to discriminate between objects and background; not in perceiving absolute depth. The findings were published in a recent Journal of Vision article, Owls see in stereo much like humans do. The purpose of the study, which was conducted at RWTH Aachen (Germany) and Radboud University (Nijmegen, Netherlands), was to uncover how depth perception came into existence during the course of evolution. "The reason why studying ...

Health care laws to protect patients' privacy make it nearly impossible for medical device designers to develop and test the safety and usability of medical products by observing use in an actual practitioner-patient setting. As a result, usability errors and hazards may be overlooked, with the potential for devastating consequences. In the recent issue of Ergonomics in Design, human factors/ergonomics researchers found that storytelling as a qualitative research method was a more effective—and stimulating—way for health care practitioners to provide valuable insights during ...

What accounts for the sounds we like to hear? Is it something about the properties of our auditory systems or brains? Or are such tastes learned? Two-month-old human infants show a preference for consonant, or gentler harmonies over more dissonant or harsher ones. But it's still impossible to know whether that preference is inborn, since the babies may have been exposed to certain sounds, even in utero. Birds show similar behaviors: they can distinguish between different kinds of sounds and certain species are attracted to certain sounds. But because no one had experimented ...

It's not just the words, but the sounds of words that have meaning for us. This is true for children and adults, who can associate the strictly auditory parts of language— vowels produced in the front or the back of the mouth, high or low pitch—with blunt or pointy things, large or small things, fast-moving or long-staying things. Do the same principles apply for young infants, and not just to things, but also to abstractions? A new study by Marcela Peña, Jacques Mehler, and Marina Nespor, working together at the International School for Advanced Studies, in Trieste, ...

RIVERSIDE, Calif. – Physicists at the University of California, Riverside report that they have discovered a new way to create positronium, an exotic and short-lived atom that could help answer what happened to antimatter in the universe, why nature favored matter over antimatter at the universe's creation. Positronium is made up of an electron and its antimatter twin, the positron. It has applications in developing more accurate Positron Emission Tomography or PET scans and in fundamental physics research. Recently, antimatter made headlines when scientists at CERN, ...

San Diego, CA, July 12, 2011 – Lack of physical exercise is often implicated in many disease processes. However, sedentary behavior, or too much sitting, as distinct from too little exercise, potentially could be a new risk factor for disease. The August issue of the American Journal of Preventive Medicine features a collection of articles that addresses many aspects of the problem of sedentary behavior, including the relevant behavioral science that will be needed to evaluate whether initiatives to reduce sitting time can be effective and beneficial. "Epidemiologic and ...

The report is on a recent provision passed by the Ohio Senate that would enact a ban on trans fats in restaurant foods. The Ohio Restaurant Association opposes the ban, saying that it would make it tough for restaurant chains to operate consistently throughout the state. Yun, however, reminds Ohioans that trans fats have no nutritional value whatsoever. "They're completely bad," he says. "No health benefits can ever come from trans fats. They should be wiped off the market, taken off the shelves (and) out of restaurants." To read the full story, ...
