TORONTO, Sept. 19, 2013—Cheque-cashing outlets may be strategically targeting persons who live in high-crime neighbourhoods, according to researchers at St. Michael's Hospital. Dr. Joel Ray, a physician-researcher at the hospital's Li Ka Shing Knowledge Institute, compared the density of cheque-cashing places in Toronto neighbourhoods with police-reported crime data. Along with his colleagues, Dr. Ray observed a nearly seven times higher rate of cheque-cashing places in neighbourhoods with the highest rate of violent crime, even after accounting for nearby retail alcohol ...

Philadelphia – The latest approach to islet transplantation, in which clusters of insulin-producing cells known as islets are transplanted from a donor pancreas into another person's liver, has produced substantially improved results for patients with type 1 diabetes, and may offer a more durable alternative to a whole pancreas transplant. Participants in the new study received islet cells isolated from the pancreas of organ donors to help their bodies produce insulin, the life-sustaining hormone responsible for absorbing glucose from the blood. The new approach, which ...

NEW YORK (September 19, 2013) -- Researchers at Weill Cornell Medical College have discovered why a tiny alteration in a brain gene, found in 20 percent of the population, contributes to the risk for anxiety, depression and memory loss. Their discovery, reported in Nature Communications, describes new functions for the alteration, a single nucleotide polymorphism (SNP) in the brain-derived neurotrophic factor (BDNF) gene. This gene is a powerful regulator of the growth and function of neurons, and the establishment of brain circuitry. The common alteration occurs when ...

Most youths are concerned about other people's feelings, they feel bad or guilty when they have done something wrong and they adhere to social rules. A small group of youths, however, does not. These youths express psychopathic personality traits that are associated with adult psychopathy, a serious personality disorder that is linked with antisocial behavior and criminality. A study conducted by Selma Salihovic and her research team at Örebro University in Sweden shows that for this small group of youth, psychopathic traits remain quite stable over a period of four years. ...

ST. LOUIS – In a recent study published in The Journal of Comparative Neurology, Saint Louis University professor of pharmacological and physiological science Michael Ariel, Ph.D., reported surprising findings about the eye movements of pond turtles who can retract their head deep into their shell. While researchers expected that the pond turtle's eyes would operate like other animals with eyes on the side of their heads, this particular species of turtle appears to have characteristics of both front and side-eyed animals, affecting a specific eye muscle's direction of ...

Working with cells in test tubes and in mice, researchers at Johns Hopkins have discovered that a chemical commonly used as a dog food preservative may prevent the kind of painful nerve damage found in the hands and feet of four out of five cancer patients taking the chemotherapy drug Taxol. The Food and Drug Administration-approved preservative, an antioxidant called ethoxyquin, was shown in experiments to bind to certain cell proteins in a way that limits their exposure to the damaging effects of Taxol, the researchers say. The hope, they say, is to build on the protective ...

Bracing in adolescents with idiopathic scoliosis reduces the likelihood that the condition will progress to the point that surgery is needed, according to a study published online today in the New England Journal of Medicine. The work was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health. Adolescent idiopathic scoliosis (AIS) is a curvature of the spine with no clear underlying cause. In mild cases, monitoring over time by a physician may be all that is needed. However, in more severe ...

WASHINGTON, Sept. 19, 2013—Today, computerized smart systems can deliver drugs intravenously in exact volumes to hospital patients. However, these systems cannot recognize which medications are in the tubing nor can they determine the concentration of the drug in the tubing. This lack of precise information can lead to medication errors with serious consequences. Now, a new optical device developed by a team of electrical and computer engineering students at the University of Illinois at Urbana-Champaign (UIUC) can identify the contents of the fluid in an intravenous ...

MINNEAPOLIS (September 19, 2013) –Algae-derived biofuel can reduce life cycle CO2 emissions by 50 to 70 percent compared to petroleum fuels, and is approaching a similar Energy Return on Investment (EROI) as conventional petroleum according to a new peer-reviewed paper published in Bioresource Technology. The study, which is the first to analyze real-world data from an existing algae-to-energy demonstration scale farm, shows that the environmental and energy benefits of algae biofuel are at least on par, and likely better, than first generation biofuels. "This study affirms ...

(Millbrook, N.Y.) Triclosan – a synthetic antibacterial widely used in personal care products – is fueling the development of resistant bacteria in streams and rivers. So reports a new paper in the journal Environmental Science and Technology, which is the first to document triclosan resistance in a natural environment. Invented for surgeons in the 1960s, triclosan slows or stops the growth of bacteria, fungi, and mildew. Currently, around half of liquid soaps contain the chemical, as well as toothpastes, deodorants, cosmetics, liquid cleansers, and detergents. Triclosan ...

A team of scientists from Canada and Australia has discovered that a decline in shark populations is detrimental to coral reefs. "Where shark numbers are reduced due to commercial fishing, there is also a decrease in the herbivorous fishes which play a key role in promoting reef health," said Jonathan Ruppert, a recent University of Toronto PhD graduate. Ruppert was part of a team engaged in long-term monitoring of reefs off Australia's northwest coast. Team leader Mark Meekan, of the Australian Institute of Marine Science (AIMS), said that the results might, at first ...

PhD candidate Marc Mitchell has published findings in the September online issue of the American Journal of Preventive Medicine suggesting that receiving coupons and vouchers for as little as five dollars can help people stick to new fitness regimes. Under the guidance of Professors Jack Goodman and Guy Faulkner, Mitchell has completed a systematic review of research into the efficacy of financial ...

Bethesda, Md. (Sept. 19, 2013)—Preeclampsia (PE) is a high blood pressure disorder that occurs during pregnancy and which can cause illness or death for the fetus and mother-to-be. There is currently no cure except to deliver the fetus, perhaps prematurely, or remove the placenta, a key organ that binds the pair. Women who smoke during pregnancy have been found to have as much as a 33 percent lower rate of preeclampsia for reasons that are unclear. A new study using an animal model to mimic key effects of PE in humans, and led by Graeme Smith of Queen's University, Canada, ...

ROCHESTER, Minn. -- Mayo Clinic researchers have shown that a specific protein pair may be a successful prognostic biomarker for identifying smoking-related lung cancers. The protein — ASCL1 — is associated with increased expression of the RET oncogene, a particular cancer-causing gene called RET. The findings appear in the online issue of the journal Oncogene. "This is exciting because we've found what we believe to be a 'drugable target' here," says George Vasmatzis, Ph.D., a Mayo Clinic molecular medicine researcher and senior author on the study. "It's a clear biomarker ...

A common songbird may have acquired genes from fellow migrating birds in order to travel greater distances, according to a University of British Columbia study published this week in the journal Evolution. While most birds either migrate or remain resident in one region, the Audubon's warbler, with habitat ranging from the Pacific Northwest to Mexico, exhibits different behaviours in different locations. The northern populations breed and migrate south for the winter, while southern populations have a tendency to stay put all year long. Evolutionary biologists have ...

Toxic metals from the only open pit mine in an estuary system in the United States are widespread in nearby sediment, water and fish and may be affecting marine and coastal animals that feed on them beyond the mine site, a new Dartmouth study finds. Mining contamination's effects on human health and aquatic and terrestrial wildlife is well documented in the United States, but the Dartmouth study is one of the first to look at the impacts of an open pit mine on an estuarine environment and the coastal marine food web. The results, which appear in the journal Archives ...

Higher calorie diets produce twice the rate of weight gain compared to the lower calorie diets that currently are recommended for adolescents hospitalized with anorexia nervosa, according to a study by researchers at UCSF Benioff Children’s Hospital. The findings will be published in the November issue of the Journal of Adolescent Health along with an accompanying editorial and two supporting studies, challenging the current conservative approach to feeding adolescents with anorexia nervosa during hospitalization for malnutrition. “These findings are crucial ...

September 20, 2013, Shenzhen, China – An international team led by South Korea's Personal Genomics Institute and BGI unraveled the first whole genome of a 9-year-old male Amur tiger (Panthera tigris altaica), and compared it with the genomes of other big cats including the white Bengal tiger, lions, and snow leopards. The genomic data from this study provides an invaluable resource for the future studies of big cats and their whole family's conservation. The latest study was published online in Nature Communications. Despite big cats' reputation for ferocity, these majestic ...

A new, non-invasive imaging technique, magnetic resonance elastography (MRE), can now help physicians accurately detect fibrosis (scarring) in children with chronic liver disease – a growing problem due in part to increasing obesity rates. A new study shows that MRE detects such chronic diseases as non-alcoholic fatty liver disease (NAFLD), which is increasingly common in children and teens, affecting an estimated 13 percent of adolescents. NAFLD can lead to progressive liver disease and liver failure. Obesity is a major risk factor. "Because many pediatrics patients ...
