New research at the University of Leicester is investigating a growing fascination with 'chav' culture among middle-class gay men in Britain. Professor Joanna Brewis, from the University of Leicester School of Management, UK, will conduct primary empirical research into gay class tourism following publication of findings reported last year in the journal Sociology. Research she carried out with her former colleague Professor Gavin Jack, now at La Trobe University in Australia, revealed the complex consumer patterns of middle-class homosexual men who go 'slumming' at ...

PHILADELPHIA — An international research team including University of Pennsylvania scientists has shown that the rate of sea-level rise along the U.S. Atlantic coast is greater now than at any time in the past 2,000 years and that there is a consistent link between changes in global mean surface temperature and sea level. The research was conducted by members of the Department of Earth and Environmental Science in Penn's School of Arts and Science: Benjamin Horton, associate professor and director of the Sea Level Research Laboratory, and postdoctoral fellow Andrew Kemp, ...

The risk of developing venous thromboembolism (VTE) may be nearly twice as high for patients undergoing open surgery for colorectal problems, versus those undergoing laparoscopic colorectal (LC) resections, according to a report in the June issue of Archives of Surgery, one of the JAMA/Archives journals. Venous thromboembolism (the formation of blood clots in the veins) occurs in up to 25 percent of patients who undergo surgery without specific steps taken to prevent the condition, according to background information in the article. The authors note that colorectal surgery ...

Most hospitals follow established practice guidelines for surgery involving Medicare beneficiaries with cancer, but in some cases their practice patterns diverge from the guidelines, according to a report published Online First today by Archives of Surgery, one of the JAMA/Archives journals. According to background information in the article, health care quality has emerged as an important concern in the United States. However, the right care is not always delivered to the right patient at the right time, the authors remark. "Currently, it is well documented that the ...

A review of tonsillectomy-technique studies found that some new methods have advantages over traditional methods, but others are equivalent, according to a report in the June issue of Archives of Otolaryngology–Head and Neck Surgery, one of the JAMA/Archives journals. As background information, the article states that tonsillectomy is well established in terms of safety, but is often accompanied by pain, postsurgical bleeding, and a prolonged recovery. Traditionally, the operation has been performed using cold steel and/or electrocautery dissection (CS/EC). Newer methods ...

Using a fluticasone furoate nasal spray for treatment of obstructive sleep apnea in children appears to reduce production of certain inflammatory cell proteins that may play a role in development of obstructive sleep apnea, according to a report in the June issue of Archives of Otolaryngology – Head & Neck Surgery, one of the JAMA/Archives journals. "Obstructive sleep apnea syndrome is characterized by prolonged partial upper airway obstruction and/or intermittent complete obstruction with disruption of normal ventilation during sleep and normal sleep patterns," the authors ...

Not all varieties of botulinum toxin seem to be equally effective in reducing crow's feet wrinkles, according to a report published Online First today by Archives of Facial Plastic Surgery, one of the JAMA/Archives journals. Botulinum toxin, a protein long considered harmful, is now known as a neuromodulator (a chemical that affects nerve impulses) that has cosmetic and medical uses, according to background information in the article. In 1989, botulinum toxin type A was approved in the United States for two muscular conditions that affect the appearance of the eyes. In ...

A newly constructed, 2,000-year history of sea level elevations will help scientists refine the models used to predict climate-change-induced sea level rise, according to an international team of climate researchers. The record also shows that the past century had the fastest recorded rate of sea level rise. "One of the largest uncertainties in projecting the impacts of climate change involve predicting the amount and rate of future sea level rise," said Michael E. Mann, professor of meteorology, Penn State. "The societal ramifications are as great as any climate change ...

Researchers at the University of California, San Diego have developed a novel method of disguising nanoparticles as red blood cells, which will enable them to evade the body's immune system and deliver cancer-fighting drugs straight to a tumor. Their research will be published next week in the online Early Edition of the Proceedings of the National Academy of Sciences. The method involves collecting the membrane from a red blood cell and wrapping it like a powerful camouflaging cloak around a biodegradable polymer nanoparticle stuffed with a cocktail of small molecule ...

A surprising finding in a study comparing hepatitis C virus (HCV) with hepatitis A virus (HAV) infections in chimpanzees by a team that includes scientists from the Texas Biomedical Research Institute sheds new light on the nature of the body's immune response to these viruses. Understanding how hepatitis C becomes chronic is very important because some 200 million people worldwide and 3.2 million people in the U.S. are chronically infected with HCV and are at risk for progression to cirrhosis and liver cancer. Hepatitis C associated liver disease is the most common ...

LOS ANGELES—(June 20, 2011)—Doctors warned of a potential public health epidemic in a recent report on patients in Los Angeles and New York who developed serious skin reactions after smoking or snorting cocaine believed to be contaminated with a veterinary medication drug dealers are using to dilute, or "cut," up to 70% of the cocaine in the U.S. The report, published online in the Journal of the American Academy of Dermatology, said six patients developed purple-colored patches of necrotic skin on their ears, nose, cheeks and other parts of their body and, in some instances, ...

Amsterdam, The Netherlands, June 20, 2011 -- After more than 100 years following its pathologic description, the cause of Alzheimer's disease (AD) remains unknown. To test the validity of present and future proposals related to the probable cause of AD, three postulates, or necessary conditions, are recommended by Jack de la Torre, MD, PhD, Adjunct Professor of Psychology at the University of Texas, Austin, in an article published in the Journal of Alzheimer's Disease. "Knowing what causes AD is critically important because it would allow more effective therapy to specifically ...

Scientists at Karolinska Institutet in Sweden have discovered that a gene linked to dyslexia has a surprising biological function: it controls cilia, the antenna-like projections that cells use to communicate. Dyslexia is largely hereditary and linked to a number of genes, the functions of which are, however, largely unknown. This present study from Karolinska Institutet and Helsinki University now shows that one of these genes, DCDC2, is involved in regulating the signalling of cilia in brain neurons. "Our discovery presents us with a possible new neurobiological ...

New research from the University of Warwick and the IZA Institute in Bonn shows that 10% of middle-aged Europeans took antidepressants in 2010. The researchers looked in detail at the lives of a randomly selected sample of nearly 30,000 Europeans. The study covered 27 countries. Andrew Oswald, an economics professor at the University of Warwick, and co-author of the study, described the results as concerning, he said: "Antidepressants are a relatively new kind of commodity. We are only starting to get proper data on who takes them. But as we live in the richest and safest ...

Although sex and infidelity are now only a keyboard away, at the end of the day, there is no substitute for physical, face-to-face contact in our sexual relationships. That's according to a new study by Diane Kholos Wysocki, from the University of Nebraska at Kearney, and Cheryl Childers, from Washburn University in Topeka, Kansas. They investigated the behaviors of infidelity on the internet and sexting - sending sexually explicit text messages and photographs via email or cell phone. Their findings are published online in Springer's journal, Sexuality & Culture. The ...

Financial services firms rely on the Financial Information eXchange (FIX) protocol to drive the real-time electronic exchange of securities transactions. However, the special message format and rigid nature of the FIX protocol mean it often interoperates poorly with non-FIX applications. The combination of the WSO2 Enterprise Service Bus (WSO2 ESB) and FIX protocol support provides a powerful solution for seamlessly integrating FIX applications and the heterogeneous systems supporting a financial firm's operations. IT architects and developers can learn how to optimize ...

University of Cincinnati analysis of hospital supply chains – how hospitals stock nursing stations with the hundreds of medicines, materials and even office supplies needed – holds promise in helping to make supply and re-supply efforts leaner and more cost effective. The research, to be presented June 22 at the Institute for Operations Research and Management Science Healthcare Conference in Montreal, has implications for affecting the significant costs associated with hospital supplies. On average, supplies and inventory account for 30 to 40 percent of an average hospital's ...

Magnetic storage media such as hard drives have revolutionized the handling of information: We are used to dealing with huge quantities of magnetically stored data while relying on highly sensitive electronic components. And hope to further increase data capacities through ever smaller components. Together with experts from Grenoble and Strasbourg, researchers of KIT's Institute of Nanotechnology (INT) have developed a nano-component based on a mechanism observed in nature. What if the very tininess of a component prevented one from designing the necessary tools for its ...

Our changing climate usually appears to be a very modern problem, yet new research from Greenland published in Boreas, suggests that the AD 1350 collapse of a centuries old colony established by Viking settlers may have been caused by declining temperatures and a rise in sea-ice. The authors suggest the collapse of the Greenland Norse presents a historical example of a society which failed to adapt to climate change. The research, led by Dr Sofia Ribeiro from the University of Copenhagen, currently at the Geological Survey of Denmark and Greenland, focused on Disko Bay ...

Dr. Kevin Sands, DDS, a Los Angeles dentist, knows exactly how patients can struggle with the appearance of their smile. The evolving world of cosmetic dentistry is giving patients with discolored, damaged and structurally imperfect teeth a new lease on their smile. Dr. Sands is now improving patient smiles by porcelain veneers to correct years of staining and abuse and to provide an attractive and confident smile. Every person is born with white teeth, but that is where the similarities cease. Elements such a heredity, infrequent dental care and oral hygiene can quickly ...

In the United States, the blood-alcohol limit may be 0.08 percent, but no amount of alcohol seems to be safe for driving, according to a University of California, San Diego sociologist. A study led by David Phillips and published in the journal Addiction finds that blood-alcohol levels well below the U.S. legal limit are associated with incapacitating injury and death. Phillips, with coauthor Kimberly M. Brewer, also of UC San Diego, examined official data from the Fatality Analysis Reporting System (FARS). This dataset includes information on all persons in the U.S. ...

This release is available in Spanish. In spite of the fact that the railway industry has two centuries of experience behind it, in order to continue improving the research being done on the safety, profitability and efficiency of railroads, it will be necessary to develop and strengthen the relationship between universities and companies in the sector. This is one of the main conclusions that have come out of an international forum on the subject that was recently held at Carlos III University of Madrid. The forum, the First European Forum on Railway Running Gears, ...

A new microspectrometer architecture that uses compact disc-shaped resonators could address the challenges of integrated lab-on-chip sensing systems that now require a large off-chip spectrometer to achieve high resolution. Spectrometers have conventionally been expensive and bulky bench-top instruments used to detect and identify the molecules inside a sample by shining light on it and measuring different wavelengths of the emitted or absorbed light. Previous efforts toward miniaturizing spectrometers have reduced their size and cost, but these reductions have typically ...
