Orlando, FL (May 20, 2013) — Research presented at Digestive Disease Week® (DDW) explores pharmaceutical advances for treating irritable bowel syndrome with diarrhea (IBS-D) and hepatitis C. An international study holds promising results for patients suffering from IBS-D. In the phase II study, researchers found that the drug ibodutant significantly improved symptoms in more than 50 percent of the individuals treated. "While there's been a lot of progress in medicines for IBS with constipation, we haven't seen the same in IBS with diarrhea," said Jan Tack, MD, professor ...

ROCHESTER, Minn. — Patients with inflammatory bowel disease (IBD) are at higher risk of melanoma, a form of skin cancer, report researchers at Mayo Clinic. Researchers found that IBD is associated with a 37 percent greater risk for the disease. The findings were presented at the Digestive Disease Week 2013 conference in Orlando, Fla. More than 1.5 million Americans have Crohn's disease or ulcerative colitis (UC), the most common forms of inflammatory bowel disease. Both conditions inflame the lining of the intestine, leading to bouts of watery diarrhea, rectal bleeding, ...

CHAMPAIGN, Ill. — In a new study described in the journal Oncogene, researchers reveal how a key player in cell growth, immunity and the inflammatory response can be transformed into a primary contributor to tumor growth. Scientists call this Jekyll-and-Hyde molecule NF-kappa B. In healthy cells, it is a powerful "first responder," a vital part of the body's immune and inflammatory responses. It spends most of its life in the cell's cytoplasm, quietly awaiting orders. But when extracellular signals – of a viral or bacterial invasion, for example – set off chemical alarms, ...

WASHINGTON, D.C., May 20, 2013 – At a time when the spotlight is focused on obesity more than ever, new research suggests that frequency of candy consumption is not associated with weight or certain adverse health risks. According to a recent data analysis published in the April 30th issue of Nutrition Journal, adults who consume candy at least every other day are no more likely to be overweight nor have greater risk factors for cardiovascular disease (CVD) than moderate consumers (about once a week) or even less frequent candy eaters (less than 3 times per month).1 Almost ...

ZURICH - Video compositing to create special effects, replace backgrounds or combine multiple takes of an actor's performance is an integral, but highly labor-intensive, part of modern film making. Researchers at Disney Research, Zürich, however, have found an innovative way to create these composite videos that is simple, fast, and easy to use. Rather than perform a painstaking segmentation of elements that are to be added or subtracted from a video, the Disney system, called DuctTake, uses computer algorithms to find a spatiotemporal "seam" through the video frame that ...

A humanoid robot can receive an object handed to it by a person with something approaching natural, human-like motion thanks to a new method developed by scientists at Disney Research, Pittsburgh in a project partially funded by the International Center for Advanced Communication Technologies (interACT) at Carnegie Mellon University and Karlsruhe Institute of Technology (KIT). Recognizing that a person is handing something and predicting where the human plans to make the handoff is difficult for a robot, but the researchers from Disney and KIT solved the problem by using ...

The study comprised over 24,000 Finnish subjects and was led by Professor Samuli Ripatti. The results revealed that a panel of 28 genetic markers improved detection of individuals with high risk for coronary heart disease (CHD) (10-year risk ≥20%) over traditional risk factors. Identification of high-risk individuals is an important preventive strategy for CHD, because the current guidelines recommend statin treatment for the high-risk group. "The results indicate that genetic markers could be useful in CHD prevention, when used in addition to traditional risk factor ...

Jerusalem, May 20, 2013 –A new study conducted using extensive medical records of over one million Israeli adolescents before military service shows clearly how exposure to the Israeli sun of young, light-skinned children increases substantially the risk of cutaneous melanoma (a serious form of skin cancer). The incidence of cutaneous melanoma is on the rise in all parts of the world where light-skinned people live. Rates have tripled over the last decades in the United States, and the rise was even steeper in Europe. What about in Israel? What segments of the population ...

A new computer model could help scientists predict when a particular strain of avian influenza might become infectious from bird to human, according to a report to be published in the International Journal Data Mining and Bioinformatics. Chuang Ma of the University of Arizona, Tucson, and colleagues at the Huazhong University of Science and Technology, Wuhan and the Wuhan Institute of Virology, explain that since 1997 several strains of avian influenza A virus (AIV), commonly known as "bird flu" have infected people directly from their natural bird hosts leading to numerous ...

A new study conducted at the University of Bristol and published online today in the Journal of Evolutionary Biology sheds light on how the brain and inner ear developed in dinosaurs. Stephan Lautenschlager from Bristol's School of Earth Sciences, together with Tom Hübner from the Niedersächsische Landesmuseum in Hannover, Germany, picked the brains of 150 million year old dinosaurs. The two palaeontologists studied different fossils of the Jurassic dinosaur Dysalotosaurus lettowvorbecki: a very young (juvenile) individual of approximately three years of age and ...

There is a link between use of anabolic-androgenic steroids and reduced mental health later in life. This is the main conclusion of a new study on elite male strength athletes that researchers from the University of Gothenburg recently published in the British Journal of Sports Medicine. Twenty per cent of the subjects in the study admitted steroid use. The study is published by CERA, which is the University of Gothenburg's centre for education and research on addiction. Together with colleagues from Sahlgrenska University Hospital, they found a connection between abuse ...

Researchers at Lund University in Sweden have mapped the significance of heredity for common forms of atherosclerotic disease. No studies have previously examined whether different forms of the disease share heredity. The study looked at coronary heart disease, ischemic stroke, peripheral arterial disease and atherosclerosis of the aorta in individuals whose siblings and parents have suffered different types of cardiovascular disease. The results showed that heredity is highest for atherosclerosis of the aorta followed by peripheral arterial disease, coronary heart disease ...

Earthquakes that last minutes rather than seconds are a relatively recent discovery, according to an international team of seismologists. Researchers have been aware of these slow earthquakes, only for the past five to 10 years because of new tools and new observations, but these tools may explain the triggering of some normal earthquakes and could help in earthquake prediction. "New technology has shown us that faults do not just fail in a sudden earthquake or by stable creep," said Demian M. Saffer, professor of geoscience, Penn State. "We now know that earthquakes ...

A new study conducted by researchers at the Child Study Center at NYU Langone Medical Center found men diagnosed as children with attention-deficit/hyperactivity disorder (ADHD) were twice as likely to be obese in a 33-year follow-up study compared to men who were not diagnosed with the condition. The study appears in the May 20 online edition of Pediatrics. "Few studies have focused on long-term outcomes for patients diagnosed with ADHD in childhood. In this study, we wanted to assess the health outcomes of children diagnosed with ADHD, focusing on obesity rates and ...

The Food and Drug Administration (FDA) and CosmosID® conducted side-by-side analysis of a number of commercially available probiotics, four of which have been reported at the American Society for Microbiology. The purpose of the tests was to compare the identity of species and strains present in the ...

New Rochelle, NY, May 20, 2013—National guidelines recommend that at-risk women be screened for elevated cholesterol levels to reduce their chances of developing cardiovascular disease. But who is 'at risk?' The results of a study by investigators at the Centers for Disease Control and Prevention (CDC) to estimate the proportion of women young and old who have cholesterol levels that meet the definition of being at-risk are reported in an article in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free ...

Tampa, FL (May 20, 2013) -- While the effects of acute stroke have been widely studied, brain damage during the subacute phase of stroke has been a neglected area of research. Now, a new study by the University of South Florida reports that within a week of a stroke caused by a blood clot in one side of the brain, the opposite side of the brain shows signs of microvascular injury. Stroke is a leading cause of death and disability in the United States, and increases the risk for dementia. "Approximately 80 percent of strokes are ischemic strokes, in which the blood ...

PORTLAND, Ore. – A new report suggests that improved health care and significant reductions in drug costs might be attained by breaking up the age-old relationship between physicians and drug company representatives who promote the newest, more costly and often unnecessary prescription drugs. This system, which has been in place for decades, at one time benefitted doctors by keeping them up to date on new medications, and always provided generous amounts of "free" samples to get patients started on the newest drugs, as well as other supplies and gifts. But it's actually ...

New research from the University of Southampton has shown that blind and visually impaired people have the potential to use echolocation, similar to that used by bats and dolphins, to determine the location of an object. The study, which is published in the journal Hearing Research, examined how hearing, and particularly the hearing of echoes, could help blind people with spatial awareness and navigation. The study also examined the possible effects of hearing impairment and how to optimise echolocation ability in order to help improve the independence and quality of ...

Philadelphia, Pa. (May 20, 2013) – Posterior fossa subdural hematoma (PFSDH) is a serious and rare condition in newborns, generally occurring after difficult deliveries. But with appropriate treatment, there's an excellent chance of good long-term outcomes even in severe cases of PFSDH, reports a study in the May issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. The results support an "aggressive" approach to evaluation and treatment—including surgery, ...

The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical current as they are threaded through a nanoscopic hole. Now, a team led by University of Pennsylvania physicists has used solid-state nanopores to differentiate single-stranded DNA molecules containing sequences of a single repeating base. The study was led by Marija Drndić, an associate professor in the Department of Physics and Astronomy in the School of Arts and Sciences, ...

Hospital emergency departments play a growing role in the U.S. health care system, accounting for a rising proportion of hospital admissions and serving increasingly as an advanced diagnostic center for primary care physicians, according to a new RAND Corporation study. While often targeted as the most expensive place to get medical care, emergency rooms remain an important safety net for Americans who cannot get care elsewhere and may play a role in slowing the growth of health care costs, according to the study. Emergency departments are now responsible for about ...
