Incidence rates of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) have increased in the U.S. This population-based study publishing in the August issue of Hepatology, a journal of the American Association for the Study of Liver Diseases, found that metabolic syndrome significantly increases risk of developing these primary liver cancers.

Researchers from the United States and Europe involved in an NIH-funded multicenter study have determined that increased body mass index (BMI) is an independent predictor of clinical decompensation in patients with compensated cirrhosis, independent of portal pressure and liver function. The findings suggest obesity accelerates cirrhosis progression and measures to reduce BMI could improve the prognosis for patients with advanced liver disease. Study details are available in the August issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases.

A team from the University has conducted a systematic study of the force applied during a stabbing and come up with the first set of penetration force data for broken glass bottles. This work has been published in the International Journal of Legal Medicine (http://www.springerlink.com/content/v21t5g05250n22xw/)

Today, the body of an ordinary family car consists of 193 different types of steel. The steel for each part of the car has been carefully selected and optimised. It is important, for example, that all parts are as light as possible because of the fuel consumption, whereas other parts of the car have to be super strong in order to protect passengers in a collision.

"The study shows that both the emotional and utility aspect of cosmetic brands have a significant impact on consumer satisfaction, but that the emotional component has a greater effect", Vanessa Apaolaza, a researcher from the UPV and lead author of the study, which has been published in the African Journal of Business Management, tells SINC.

RIVERSIDE, Calif. (www.ucr.edu) -- Do people believe good and bad luck can be washed away?

(Edmonton) Two University of Alberta researchers have published a step by step plan to one-day end the use of environmentally harmful chemicals on commercial crops by developing plants that produce their own fertilizer.

CAMBRIDGE, Mass. -- As workers continue to grapple with the damaged Fukushima Daiichi nuclear powerplant in Japan, the crisis has shone a spotlight on nuclear reactors around the world. In June, The Associated Press released results from a yearlong investigation, revealing evidence of "unrelenting wear" in many of the oldest-running facilities in the United States.

In the study, University of Illinois law professor Jay P. Kesan and Timothy A. Slating, a regulatory associate with the University of Illinois Energy Biosciences Institute, argue that regulatory innovations are needed to keep pace with technological innovations in the biofuels industry.

In a paper published in the Ohio State Entrepreneurial Business Law Journal, law professor Christine Hurt argues that giving regulators unprecedented power to prohibit certain types of private compensation under the guise of minimizing systemic risk in the financial system is an unwise move that could ultimately undermine the freedom of contracts.

Craig Gundersen, a professor of agricultural and consumer economics at Illinois, says food and exercise alone are not to blame for the extent of obesity among children in the United States. Psychosocial factors, such as stressors brought about by uncertainty about the economy, income inequality, and a fraying social safety net also must be considered, he says.

Elizabeth T. Powers, a professor of economics and faculty member of the Institute of Government and Public Affairs at Illinois, says that a government-sponsored wage-subsidy program could reduce the churn of low-wage caregivers through group homes by one-third.

A fungus that lives at extremely high temperatures could help understand structures within our own cells. Scientists at the European Molecular Biology Laboratory (EMBL) and Heidelberg University, both in Heidelberg, Germany, were the first to sequence and analyse the genome of a heat-loving fungus, and used that information to determine the long sought 3-dimensional structure of the inner ring of the nuclear pore. The study was published today in Cell.

Chicago, IL (July 21, 2011)—A study in the August issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America (SHEA), suggests that documentation of hepatitis B vaccination for health care students may fall short of current recommendations.

Chicago, IL—Infection control researchers investigating a rare bacterial outbreak of Burholderia cepacia complex (Bcc) identified contaminated nasal spray as the root cause of the infections, leading to a national recall of the product. An article in the August issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America (SHEA), describes how researchers were able to trace the outbreak back to the nasal decongestant spray.

Sexual transmission of hepatitis C virus (HCV) is considered rare. But a new study by researchers at Mount Sinai School of Medicine, working with the Centers for Disease Control and Prevention (CDC), provides substantial evidence that men with HIV who have sex with other men (MSM) are at increased risk for contracting HCV through sex.

An invasive insect, hemlock woolly adelgid, has been marching north along the Appalachians, killing almost every hemlock tree in its path. The adelgid has devastated forests in Georgia, Tennessee, and Virginia. The pest recently arrived in Vermont and other parts of New England. So far, only extreme cold stops the adelgid.

"The impact to the exoplanet would be completely different than what we see in our solar system, and much more violent," said co-author Vinay Kashyap of CfA.

"We initially found out by accident that modified rhodium reacts in a colourful way to different gases," says Cathleen Crudden, a professor in the Department of Chemistry. "That happy accident has become a driving force in our work with rhodium."
