A new study has found that patients with chronic myeloid leukemia (CML) who have not responded to interferon treatments experience long-term benefits when they switch to the targeted drug imatinib. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study indicates that imatinib is the treatment of choice for these patients. Imatinib, a drug that blocks the protein made by a particular cancer-causing gene, has revolutionized the treatment and prognosis of patients with CML. Now up to 93 percent of patients who take the drug as ...

PASADENA, Calif., (February 27, 2012) – Children and adolescents who are overweight or obese are more likely to have asthma than their healthy weight counterparts, according to a new Kaiser Permanente Southern California study published in the online edition of Obesity. The study, which included more than 681,000 children between ages 6 and 19, found that the association between asthma and body mass index varied by race and ethnicity. The study found that the association between BMI and asthma was weaker for African Americans, a group that was previously known to have ...

Millions of adults suffer from the incurable disease multiple sclerosis (MS). It is relatively certain that MS is an autoimmune disease in which the body's own defense cells attack the myelin in the brain and spinal cord. Myelin enwraps the nerve cells and is important for their function of transmitting stimuli as electrical signals. There are numerous unconfirmed hypotheses on the development of MS, one of which has now been refuted by the neuroimmunologists in their current research: The death of oligodendrocytes, as the cells that produce the myelin sheath are called, ...

Mathematically, is it possible to continuously deform a rough sphere into a perfect sphere? Under what situations can we solve the differential equations? Professor Xu Xingwang of the Department of Mathematics at National University of Singapore (NUS), along with Dr Chen Xuezhang from Nanjing University of China, has established a new method to tackle this long-standing problem. What it used to be Of the various different ways to measure the roughness of the sphere, the scalar curvature measurement has proven to be the weakest one, resulting in a problem commonly known ...

Web applications such as Google Mail, Facebook and Amazon are used every day. However, so far there are no methods to test them systematically and at low cost for malfunctions and security vulnerabilities. Therefore, computer scientists from Saarland University are working on automatic methods of testing, which check complex web applications autonomously. For the first time, they will present this work at exhibition booth F34 in hall 26 at the computer fair Cebit. The trade show will take place from March 6 to 10 in Hannover. "Ineffective and inefficient" is Valentin ...

People like to keep a safe distance from explosive substances, but in order to analyze them, close contact is usually inevitable. At the Vienna University of Technology, a new method has now been developed to detect chemicals inside a container over a distance of more than a hundred meters. Laser light is scattered in a very specific way by different substances. Using this light, the contents of a nontransparent container can be analyzed without opening it. Scattered Light as a "Chemical Fingerprint" "The method we are using is Raman-spectroscopy", says Professor Bernhard ...

This study is part of broader research that these scientists are carrying out on the imbalance of the sexes in China and its potential consequences. This phenomenon started to be noticed during the nineteen eighties and can currently be seen in the birth rate of approximately 120 boys for every 100 girls born in the People's Republic of China. The objective of this research is precisely to analyze the effects that this disproportion can have on this society and to attempt to prevent the possible negative results it may produce. The researchers estimate that approximately ...

New research has shown that visual alerting methods are still considered to be the most trustworthy, as compared to auditory or tactile alerts. This is shown by research conducted by a team of scientists at Old Dominion University in Norfolk, VA, USA. The research Alert Characteristics and Identification of Avatars on a Virtual Battlefield by James P. Bliss, Rachel Liebman and J. Christopher Brill is published in the current issue (6:2) of the journal Intelligent Decision Technologies. Most research to date has been limited to the visual or auditory signal modality. ...

Why is it that Mycobacterium tuberculosis can cause tuberculosis with as little as 10 cells, whereas Vibrio cholerae requires the host to ingest up to tens of millions of cells to cause cholera? This is the question that two research teams, from the Pasteur Institute, in France, and the Instituto Gulbenkian de Ciencia and the University of Lisbon, in Portugal, answer in the latest issue of the journal PLoS Pathogens. The researchers show that bacteria that are able to invade and/or destroy cells of the host's immune system have higher infectivity, whereas those that are ...

WASHINGTON, Feb. 27—A team of researchers in Germany has created a new way to overcome many of the issues associated with bringing high-speed digital communications across challenging terrain and into remote areas, commonly referred to as the "last mile" problem. The researchers developed a record-speed wireless data bridge that transmits digital information much faster than today's state-of-the-art systems. These unprecedented speeds, up to 20 billion bits of data per second, were achieved by using higher frequencies than those typically used in mobile communications—the ...

Researchers of VTT Technical Research Centre of Finland have shown that surface tension on a solid material is unconnected to the energy required to create a new surface. Consequently, surface tension on a solid does not exist in its conventional meaning. It is generally believed that an excess surface tension on a solid material exists, in similar manner to that on a liquid. This tension is described by the Shuttleworth equation, which was presented more than 60 years ago and is considered a fundamental equation of surface thermodynamics. It is believed to provide the ...

Cambridge, Mass. - February 27, 2012 - In 2009, when the United States fell into economic recession, greenhouse gas emissions also fell, by 6.59 percent relative to 2008. In the power sector, however, the recession was not the main cause. Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have shown that the primary explanation for the reduction in CO2 emissions from power generation that year was that a decrease in the price of natural gas reduced the industry's reliance on coal. According to their econometric model, emissions could be cut ...

No matter how health conscious Californians would like to be, injuries, accidents, and illnesses are a fact of life. These unfortunate mishaps can pop up without a warning and send even the healthiest of people into the emergency room or to a doctor. This has left millions of Californians unsure of where to turn for health coverage for them and their families. In an attempt to make this process just a little bit smoother, the leading provider for health insurance in California, Sofi Insurance, is now offering free consultations to all customers before they make that final ...

An emerging class of long-lasting flu vaccines could do more than just save people the trouble of an annual flu shot. Princeton University-based researchers have found that the "universal" vaccine could for the first time allow for the effective, wide-scale prevention of flu by limiting the influenza virus' ability to spread and mutate. Universal, or cross-protective, vaccines — so named for their effectiveness against several flu strains — are being developed in various labs worldwide and some are already in clinical trials. The researchers recently reported in the ...

One of the toughest parts about making that first appointment to a new dentist is wondering what is going to happen during the checkup and how much it will cost. New patients may be fearful of expensive procedures or health conditions in their mouth that may cause serious issues down the road. Unfortunately, this has kept many Southern California residents from picking up the phone. This is why the leading West Hollywood cosmetic dentist, Dr. Poneh Ghasri, is now offering a new patient special for dental exam and x-ray that will lead patients to the healthiest smile of ...

Researchers at the Institut Català de Paleontologia Miquel Crusafont (ICP), the Museu de la Conca Dellà (MCD) and the Universitat Autònoma de Barcelona (UAB) have published this week in the online edition of the journal Cretaceous Research the discovery and description of a turtle from the end of the age of dinosaurs. Josep Marmi, Angel Lujan, Angel Galobart from ICP, Rodrigo Gaete from MDC, and Violeta and Oms Oriol Riera from UAB have named this new species as Polysternon isonae, in recognition of the municipality of Isona I Conca Dellà (Catalonia, Spain), where the ...

Contrary to the common perception among physicians that poor people sue doctors more frequently, Ramon L. Jimenez from the Monterey Orthopaedic and Sports Medicine Institute and his team demonstrate that socioeconomically disadvantaged patients, in fact, tend to sue physicians less often. Their work suggests that this myth may exist because of subconscious prejudices or stereotypes that affect thinking and decision making without doctors being aware of it - a phenomenon known as unconscious bias. Dr. Jimenez and his colleagues' work is published online in Springer's journal, ...

A nationwide study of racioethnic representation between retail employees and their customers finds that mirroring a customer base improves consumer satisfaction and employee productivity – and contributes to nearly $100,000 in annual gains or losses per store. Analyzing data from 739 outlets of a major U.S. department store, the researchers found that representativeness improved customer satisfaction and increased annual productivity by $625 per employee. Given the study's average sample size of 150 employees per store, such a change amounts to about $94,000 per store, ...

WASHINGTON – Employees on sick leave with common mental health disorders such as depression and anxiety fully returned to work sooner when therapy deals with work-related problems and how to get back on the job, according to new research published by the American Psychological Association. Employees who received this therapy and returned to work sooner did not suffer adverse effects and showed significant improvement in mental health over the course of one year, according to the article, published online in APA's Journal of Occupational Health Psychology. "People with ...

New York City Bus and Subway Accidents: MTA Whether they take the train, subway or bus, New Yorkers put a great deal of trust into the New York Metropolitan Transportation Authority (MTA). They expect to get where they need to go -- work, school, the grocery store -- safely and on time. They expect that the MTA will frequently inspect trains and buses, and take other measures to ensure riders' safety. What happens when that trust is broken, when a bus or train accident causes serious injury? While the New York City subway and bus systems are generally safe, accidents ...
