Patients with severe sleep-disordered breathing are two to four times more likely to experience complex, abnormal heart rhythms while sleeping than individuals without the problem, according to the Sleep Heart Health Study (SHHS).

These findings appear in the April 15 issue of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society.

There will be 78.08 million 3G users in China by the year 2008, according to a report by Analysys International, an Internet-based provider of technology business information.

According to the report, telecoms operators will begin construction of 3G networks and purchase of 3G devices as soon as 3G licenses are issued in China in the second half of this year. 3G mobile communication services will be provided in China in the first half of 2007 while mature 3G commercial applications will b

Self-employed male Britons have been found to work longer hours for lower wages than those of their employee counterparts. This is attributed to them facing greater uncertainty and so working harder as a way to insure their future livelihoods. In addition, according to the research funded by the Economic and Social Research Council, there was no evidence of growing female self-employment, or the anticipated greater labour flexibility resulting from self-employment during the 1990s.

When asked, both consumers and advertisers agree that conspicuous white space around a word or image – epitomized by the design of Real Simple magazine – associate a product with refined taste and upscale qualities. However, in the first paper to trace the history of white space in advertising, researchers from University of Alberta and the University of Illinois at Champaign-Urbana argue that the meaning of this design element comes not from its inherent features, but from relatively recent art h

Survival rates following the most common form of cardiac arrest increased three-fold when emergency medical personnel used a new form of CPR developed at The University of Arizona Sarver Heart Center. The new approach, called Cardiocerebral Resuscitation, is dramatically different from guideline-directed CPR procedures.

Because of its importance, the editors of the American Journal of Medicine chose to publish the report online in advance of the journal’s April print is

It looks so simple – catching a fly ball. But of all of the balls hit into the outfield, the straight shot is the most difficult to catch. And if it’s twilight, it’s even worse.

Ken Fuld, professor of psychology at the University of New Hampshire, studies visual psychophysics. A former assistant baseball coach at UNH with a son playing for one of the Chicago Cubs minor league teams, Fuld says there’s more than meets the eye to catching fly balls and hitting pitches for the boys o

Study finds that people are more willing to lie to coworkers than to strangers

Though explicit talk of money may be considered gauche, we are frequently confronted with the dreaded query “How much did you pay for that?” Our response to being put on the spot? Lies. But a new study in the June issue of the Journal of Consumer Research found that we are more likely to muddle the truth with our coworkers than with perfect strangers.

Interestingly, the researchers also found

A study in the June issue of the Journal of Consumer Research reveals that some people don’t go for products marketed as better or more effective than its rivals. Individuals who focus on potential gains will go for a product advertised as far superior to its competitors. However, those concerned with potential losses will disregard such campaigns in favor of comparisons that claim a product is similar to or just as good as established brands.

“Our results are novel in suggesting

UC study is first to demonstrate that this specific receptor is working in breast cancer cells and can be “turned on” by excessive estrogen.

A hormone receptor with regulatory roles as diverse as food intake, fear response, and cardiovascular function may also be involved in breast cancer, according to UC researchers.

The UC research team, led by Hassane Amlal, PhD, and Sulaiman Sheriff, PhD, report their laboratory findings on the hormone, neuropeptide Y, and its rece

A courtroom jury views a computer animation of a vehicle accident or heinous crime. Does it help bring a conviction or acquittal? With no clear standards for animations that re-create incidents, the verdict is still out, and, for now, it may depend on which side created the simulation, researchers say.

In a study of 117 undergraduate students, psychologists discovered that movements in a sequence of events, as well as the duration portrayed, in animations such as re-creations

Based on data obtained from one of the largest family sets of its kind, Yale School of Medicine researchers have identified a genetic linkage for dependence on drugs such as heroin, morphine and oxycontin.

The lead author, Joel Gelernter, M.D., professor in the Department of Psychiatry, said the researchers recruited a sample of 393 small families, most with at least two individuals with opioid dependence. They then searched genetic signposts throughout the entire genome i

Chronic pain, which is any physical discomfort lasting for at least six months, affects up to 50 million Americans, most of whom work full time. Common forms of chronic pain include headaches, backaches, arthritis, respiratory conditions, and ailments caused by sports injuries or other traumas, such as car accidents.

Wayne Hochwarter, an associate professor of management in Florida State University’s College of Business in Tallahassee, Fla., has conducted several studies to ex

In the nation’s first statewide study of its kind, the Injury Research Center of the Medical College of Wisconsin in Milwaukee has revealed new data on an old problem… people who don’t use seatbelts. The researchers found that unbelted crash occupants who make it to an emergency department alive are more than three times as likely as belt users to die.

The team used data from the 2002 Crash Outcome Data Evaluation System (CODES)* for Wisconsin. They studied 23,920 crash occu

Researchers say surgery is best care for fastest growing cancer type

In part because the nature of the disease has changed, nearly 50 percent of patients with esophageal cancer that undergo an advanced surgical procedure now survive for five years, not 20 percent as once thought, according to an article published in the April edition of the Journal of the American College of Surgeons. Researchers at the University of Rochester Medical Center contend that earlier diagnoses, more

A social psychologist at the University of Alberta claims that people who do not wear wedding rings are more neglectful of children compared to people who wear them. Further, Dr. Andrew Harrell states that young attractive people who do not wear wedding rings are the most neglectful child caretakers of all.

The director of the U of A Population Research Lab, Harrell made his conclusions after leading an experiment in which 862 caretaker-children combinations were furtively obser

Studies have demonstrated an association between periodontal therapy and improved metabolic control in diabetic patients. This study supports findings related to this association.

Results of a new study support the hypothesis that periodontal therapy may improve metabolic control (lower HbA1c) in diabetic patients. This study appears in April’s issue of the Journal of Periodontology.

The results suggest that periodontal therapy may reduce a diabetic patient’s
