After the recorder, the violin is the instrument most commonly offered to children by state schools in the UK. The violin is a challenging instrument. Rapid, independent motion of the digital joints in the left hand is desirable. This study was conceived after an 11-year-old patient volunteered that she had given up playing the violin because of difficulty and discomfort manoeuvring the left small and ring fingers independently. On exami¬nation, she was found to have absent FDS (flexor digitorum superficialis) function in the small finger. The research investigated whether ...

Two wasp species, Calymmochilus dispar and Gelis apterus, have been recorded as parasitoids on ant-eating spiders in a study published in the open access journal ZooKeys. The host spider, Zodarion styliferum, belongs to the largest genus of predominantly ant-eating spiders. Their distribution area includes Europe, Asia and North Africa, significantly with at least 35 species reported for the Iberian Peninsula only, marking a record in numbers in Portugal, where this study was conducted. Available data on the biology of the host spider shows that all species of the genus ...

Examining the UK Clinical Practice Research Datalink (CPRD) - data that characterises about 10% of the UK population - a team of researchers from Cardiff University's School of Medicine looked at the risk of death for patients taking insulin compared with other treatments designed to lower blood glucose levels in people with type 2 diabetes. The team's epidemiological study found people have greater risk of individual complications associated with diabetes such as heart attack, stroke, eye complications and renal disease when compared with patients treated with alternative ...

This press release is available in German. Thanks to the strange laws of quantum mechanics, quantum computers would be able to carry out certain computational tasks much faster than conventional computers. Among the most promising technologies for the construction of a quantum computer are systems of single atoms, confined in so-called ion traps and manipulated with lasers. In the laboratory, these systems have already been used to test key building blocks of a future quantum computer. "Currently, we can carry out successful quantum computations with atoms," explain ...

SEATTLE – Patients whose aggressive lymphomas have relapsed or failed to respond to the current front-line chemotherapy regimen now have an effective second line of attack against their disease. Reporting the results of a first-of-its-kind phase 1 clinical trial to test the effectiveness of a new class of drugs to augment standard chemotherapy, a team led by Fred Hutchinson Cancer Research Center scientists found that giving patients high doses of Vorinostat (suberoylanilide hydroxamic acid) in combination with another round of commonly used second-line drugs resulted in ...

Feeling shame about past instances of problem drinking may increase the likelihood of relapse and other health problems, according to a new study in Clinical Psychological Science, a journal of the Association for Psychological Science. The study, conducted by researchers from the University of British Columbia, shows that behavioral displays of shame strongly predicted whether recovering alcoholics would relapse in the future. Public shaming has long been viewed as a way to encourage people to amend their ways and research suggests that experiences of shame can motivate ...

Ottawa, ON (February 4, 2013) – People tend to lose muscle mass as they age; researchers are investigating ways to delay or counteract age-related muscle loss. A study conducted by the Exercise Metabolism Research Group at McMaster University suggests that current guidelines for meat consumption are based on the protein needed to prevent deficiency without consideration for preservation of muscle mass, particularly for older individuals who are looking to maintain their muscle as they age. This research was published in the journal Applied Physiology, Nutrition, and Metabolism. Thirty-five ...

"I am proud to honor these inspiring American innovators," Obama said when the awardees were announced. "They represent the ...

Reston, Va. – While amyloid imaging may now be most associated with detecting plaques in the brain, it has the potential to change the way cardiac amyloidosis is diagnosed. According to first-of-its-kind research published in the February issue of The Journal of Nuclear Medicine, positron emission tomography (PET) with 11C-PIB can positively visualize amyloid deposits in the heart. Currently there is no noninvasive test available for specific diagnosis. Cardiac amyloidosis is a deadly disorder caused by abnormal amyloid deposits in the heart tissue. Early diagnosis before ...

This press release is available in Spanish. Farmers can fine-tune their use of cover crops to help manage costs and maximize benefits in commercial organic production systems, according to U.S. Department of Agriculture (USDA) scientists. Production expenses for high-value organic crops like lettuce and broccoli can exceed $7,000 per acre, so producers often try to streamline costs with an annual two- to three-crop rotation. Agricultural Research Service (ARS) horticulturalist Eric Brennan designed a long-term investigation that examined several different cover ...

Ann Arbor, Mich. — In the beloved American stories of the Little House on the Prairie, author Laura Ingalls Wilder writes emotionally about how scarlet fever robs her big sister Mary of her sight. But in a new study published today in the journal Pediatrics, University of Michigan researchers found it is likely scarlet fever had nothing to do with Mary's blindness. Senior author Beth A. Tarini, M.D., and her co-authors used evidence from newspaper reports, Laura Ingalls' memories and school registries to conclude Mary's blindness was probably caused by viral meningoencephalitis. "Since ...

Though a small group of proteins, the family called Ras controls a large number of cellular functions, including cell growth, differentiation, and survival. And because the protein has a hand in cellular division, mutated Ras, which can be detected in one-third of all tumors, contributes to many human cancers by allowing for the rapid growth of diseased cells. Now Prof. Yoel Kloog of Tel Aviv University's Department of Neurobiology, along with Dr. Itamar Goldstein of TAU's Sackler Faculty of Medicine and the Sheba Medical Center and their students Helly Vernitsky and ...

PROVIDENCE, R.I. [Brown University] — Studies have found that conditional cash transfer programs, in which governments pay citizens if they consistently practice societally beneficial behaviors, have improved pediatric health care and education in Mexico, increased HIV testing in Malawi, and reduced sexually transmitted infections in Tanzania. Public health researchers therefore investigated whether the idea could be applied to HIV risk behaviors among gay men and male sex workers in Mexico City. A new study reports not only that some members of those populations would ...

A new kind of pterosaur, a flying reptile from the time of the dinosaurs, has been identified by scientists from the Transylvanian Museum Society in Romania, the University of Southampton in the UK and the Museau Nacional in Rio de Janiero, Brazil. The fossilised bones come from the Late Cretaceous rocks of Sebeş-Glod in the Transylvanian Basin, Romania, which are approximately 68 million years old. The Transylvanian Basin is world-famous for its many Late Cretaceous fossils, including dinosaurs of many kinds, as well as fossilised mammals, turtles, lizards and ancient ...

Philadelphia, Pa. (February 4, 2013) - Visual symptoms and abnormalities occur at high rates in people with traumatic brain injury (TBI)—including Iraq and Afghanistan War veterans with blast-related TBI, reports a study, "Abnormal Fixation in Individuals with AMD when Viewing an Image of a Face", in the February issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Vision problems are similar for military and civilian patients with TBI, ...

DENVER (Feb. 4, 2013) – Unfriending someone on Facebook may be as easy as clicking a button, but a new study from the University of Colorado Denver shows the repercussions often reach far beyond cyberspace. "People think social networks are just for fun," said study author Christopher Sibona, a doctoral student in the Computer Science and Information Systems program at the University of Colorado Denver Business School. "But in fact what you do on those sites can have real world consequences." Sibona found that 40 percent of people surveyed said they would avoid in real ...

ST. LOUIS – In research published in the Jan. 24 edition of PLOS Pathogens, Saint Louis University investigators together with collaborators from the University of Missouri and the University of Pittsburgh report a breakthrough in the pursuit of new hepatitis B drugs that could help cure the virus. Researchers were able to measure and then block a previously unstudied enzyme to stop the virus from replicating, taking advantage of known similarities with another major pathogen, HIV.

When doctors at the University of Iowa prepared a patient to inhale a panic-inducing dose of carbon dioxide, she was fearless. But within seconds of breathing in the mixture, she cried for help, overwhelmed by the sensation that she was suffocating. The patient, a woman in her 40s known as SM, has an extremely rare condition called Urbach-Wiethe disease that has caused extensive damage to the amygdala, an almond-shaped area in the brain long known for its role in fear. She had not felt terror since getting the disease when she was an adolescent. In a paper published ...

San Francisco, CA, February 4, 2012 – The Vision Screening Committee of the American Association for Pediatric Ophthalmology and Strabismus, the professional organization for pediatric eye care, has revised its guidelines for automated preschool vision screening based on new evidence. The new guidelines are published in the February issue of the Journal of AAPOS. Approximately 2% of children develop amblyopia, sometimes known as "lazy eye" – a loss of vision in one or both eyes caused by conditions that impair the normal visual input during the period of development of ...

February 4, 2013, New York, NY and Oxford, UK – Nearly every cell in the human body carries a copy of the full human genome. So how is it that the cells that detect light in the human eye are so different from those of, say, the beating heart or the spleen? The answer, of course, is that each type of cell selectively expresses only a unique suite of genes, actively silencing those that are irrelevant to its function. Scientists have long known that one way in which such gene-silencing occurs is by the chemical modification of cytosine—one of the four bases of DNA that ...

New University of East Anglia research into the mating habits of a critically endangered sea turtle will help conservationists understand more about its mating patterns. Research published today in Molecular Ecology shows that female hawksbill turtles mate at the beginning of the season and store sperm for up to 75 days to use when laying multiple nests on the beach. It also reveals that these turtles are mainly monogamous and don't tend to re-mate during the season. Because the turtles live underwater, and often far out to sea, little has been understood about their ...

PHILADELPHIA - Double-strand breaks in DNA happen every time a cell divides and replicates. Depending on the type of cell, that can be pretty often. Many proteins are involved in everyday DNA repair, but if they are mutated, the repair system breaks down and cancer can occur. Cells have two complicated ways to repair these breaks, which can affect the stability of the entire genome. Roger A. Greenberg, M.D., Ph.D., associate investigator, Abramson Family Cancer Research Institute and associate professor of Cancer Biology at the Perelman School of Medicine, University of ...

After an intensive three-year hunt through the genome, medical researchers have pinpointed mutations that leads to drug resistance and relapse in the most common type of childhood cancer—the first time anyone has linked the disease's reemergence to specific genetic anomalies. The discovery, co-lead by William L. Carroll, MD, director of NYU Langone Medical Center's Cancer Institute, is reported in a study published online February 3, 2013, in Nature Genetics. "There has been no progress in curing children who relapse, in spite of giving them very high doses of chemotherapy ...
