Experts voice concerns over arsenic in rice, reports Journal of Pediatric Gastroenterology and Nutrition

July 15, 2014 – Inorganic arsenic in rice and rice-based foods poses health concerns in infants and young children, and steps should be taken to minimize exposure, according to a commentary in the Journal of Pediatric Gastroenterology and Nutrition, official journal of the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition.

Scientists gear up to fight deadly snake fungal disease

CHAMPAIGN, Ill. — Researchers have developed a faster and more accurate way to test for infection with Ophidiomyces ophiodiicola, a fungus that is killing snakes in the Midwest and eastern United States. The test also allows scientists to monitor the progression of the infection in living snakes.

The researchers reported on the test at the 2014 Mycological Society of America Annual Meeting.

From AGU's blogs: Global climate models fail to simulate key dust characteristics

Climate models that simulate the airborne African dust that influences Atlantic Ocean hurricanes are not up to the task of accurately representing the characteristics of that dust, according to a new study accepted for publication in Geophysical Research Letters.

New UK study helps scientists understand melanoma development

LEXINGTON, Ky. (July 15, 2014) — A new study by University of Kentucky researchers shows how a genetic defect in a specific hormonal pathway may make people more susceptible to developing melanoma, the deadliest type of skin cancer.

SLU scientists hit 'delete': Removing regions of shape-shifting protein explains how blood clots

ST. LOUIS – In results recently published in Proceedings of the National Academy of Sciences (PNAS), Saint Louis University scientists have discovered that removal of disordered sections of a protein's structure reveals the molecular mechanism of a key reaction that initiates blood clotting.

Enrico Di Cera, M.D., chair of the Edward A. Doisy department of biochemistry and molecular biology at Saint Louis University, studies thrombin, a key vitamin K-dependent blood-clotting protein, and its inactive precursor prothrombin (or coagulation factor II).

New skin gel fights breast cancer without blood clot risk

CHICAGO --- A gel form of tamoxifen applied to the breasts of women with noninvasive breast cancer reduced the growth of cancer cells to the same degree as the drug taken in oral form but with fewer side effects that deter some women from taking it, according to new Northwestern Medicine® research.

Tamoxifen is an oral drug that is used for breast cancer prevention and as therapy for non-invasive breast cancer and invasive cancer.

Game theory model reveals vulnerable moments for cancer cells' energy production

Cancer's no game, but researchers at Johns Hopkins are borrowing ideas from evolutionary game theory to learn how cells cooperate within a tumor to gather energy. Their experiments, they say, could identify the ideal time to disrupt metastatic cancer cell cooperation and make a tumor more vulnerable to anti-cancer drugs.

Adolescent males seek intimacy and close relationships with the opposite sex

July 15, 2014 -- Teenage boys desire intimacy and sex in the context of a meaningful relationship and value trust in their partnerships, according to researchers at Columbia University's Mailman School of Public Health. The research provides a snapshot of the development of masculine values in adolescence, an area that has been understudied. Findings are online in the American Journal of Men's Health.

Oetzi's 'non-human' DNA

Much of what we know about Oetzi – for example what he looked like or that he suffered from lactose intolerance – stems from a tiny bone sample which allowed the decoding of his genetic make-up. Now, however, the team of scientists have examined more closely the part of the sample consisting of non-human DNA.

New mite species from a Caribbean mesophotic coral ecosystem named after J.Lo

During a recent survey of organisms collected from Bajo de Sico, a mesophotic coral reef ecosystem in Mona Passage off Puerto Rico, one pontarachnid mite species new to science was discovered. The new species was named after the famous Puerto Rican singer Jennifer Lopez. The study was published in the open access journal ZooKeys.

To accept or not accept -- Patients want a say in liver transplant decisions

A novel study reveals that more than half of liver transplant patients want to be informed of donor risk at the time a liver is offered for transplantation. Nearly 80% of those patients want to be involved in the decision of whether or not to accept the organ according to findings published in Liver Transplantation, a journal of the American Association for the Study of Liver Diseases and the International Liver Transplantation Society.

New hope for treatment of Alzheimer's disease

Montreal, July 15 2014 - Judes Poirier, PhD, C.Q., from the Douglas Mental Health Institute and McGill University in Montréal (Canada) and his team have discovered that a relatively frequent genetic variant actually conveys significant protection against the common form of Alzheimer's disease and can delay the onset of the disease by as much as 4 years. This discovery opens new avenues for treatment against this devastating disease.

Cholesterol activates signaling pathway that promotes cancer

Everyone knows that cholesterol, at least the bad kind, can cause heart disease and hardening of the arteries. Now, researchers at the University of Illinois at Chicago describe a new role for cholesterol in the activation of a cellular signaling pathway that has been linked to cancer.

The finding is reported in Nature Communications.

Researchers assess emergency radiology response after Boston Marathon bombings

OAK BROOK, Ill. – An after-action review of the Brigham and Women's Hospital emergency radiology response to the Boston Marathon bombings highlights the crucial role medical imaging plays in emergency situations and ways in which radiology departments can improve their preparedness for mass casualty events. The new study is published online in the journal Radiology.

No anti-clotting treatment needed for most kids undergoing spine surgeries

Blood clots occur so rarely in children undergoing spine operations that most patients require nothing more than vigilant monitoring after surgery and should be spared risky and costly anti-clotting medications, according to a new Johns Hopkins Children's Center study.

Because clotting risk in children is poorly understood, treatment guidelines are largely absent, leaving doctors caring for pediatric patients at a loss on whom to treat and when.
