This study was aimed at the detection of lung cancer in its early stages amongst high-risk persons by means of Computerised Axial Tomography (CAT).
Currently, 85% of cases are diagnosed at a late stage, which considerably reduces the rate of cure.
Lung cancer is the most common carcinoma in western countries and the one that causes most deaths; more than those caused by breast cancer, cancer of the colon and prostate cancer put together.

Men estimate men’s risks of common disorders higher than women do, and vice versa
New research from University of Glasgow researchers on lay perceptions about gender differences in health reveals that both men and women believe health risks are higher for their own sex than for the opposite sex. But, it also shows that males think that men are fitter and females think women are more athletic.

Europe’s growth slowed in the 1990s, reinforcing the overall impression of a need to catch up with the US regarding standards of living. In reaction, EU leaders adopted the famous Lisbon Agenda in 2000. The Agenda is now under review, the aim being to determine why progress on its pro-growth goals has been unsatisfactory and what can be done about it. The first crucial step in this process is to understand the true sources of the European growth slowdown. Sources-of-growth calculations have al
Results suggest CT perfusion improves outcomes
Interventional neuroradiologists at West Virginia University School of Medicine and Hospitals today presented the largest study to date on the utility of computed tomography (CT) perfusion imaging of the brain in determining and predicting stroke outcomes. Results will help better identify patients who are suitable candidates for treatment utilizing either clot busting medicines or clot retrieval devices. The research was presented to
The federal government should create and fund an umbrella organization called the United States Global Health Service (GHS) to mobilize the nation’s best health care professionals and other experts to help combat HIV/AIDS in hard-hit African, Caribbean, and Southeast Asian countries, says a new report from the Institute of Medicine of the National Academies. Full-time, salaried professionals would make up the organization’s pivotal “service corps,” working side by side with other colleagues al
Some low birth weight infants have large particles rich in apolipoprotein C-1, a blood protein that could put them at risk for heart disease later in life, according to a national study led by Johns Hopkins Children’s Center researchers.
For the study, Peter O. Kwiterovich, Jr., M.D., professor of pediatrics and director of the Lipid Clinic at Johns Hopkins, and colleagues analyzed the umbilical cord blood of 163 infants born at 28 or more weeks of gestational age at Johns Ho
Rice farming led to growth of ancient cities
The rapid growth of the earliest cities in northern China starting as far back as 2400 to 2000 BC is the result of successful rice farming combined with other crops, says University of Toronto anthropologist Gary Crawford.
Although we often associate rice with Chinese agriculture, most archeologists have, until recently, thought it was exclusively millet that was the most important food associated with northern China. However
U of T researchers develop new chemical reaction
University of Toronto researchers have a developed a new chemical reaction that could greatly accelerate pharmaceutical production, while also cutting costs and toxic by-products.
The reaction, designed by chemistry Professor Mark Lautens and graduate student Eric Fang, simplifies the creation of the basic molecular framework found in many natural products and popular pharmaceuticals like some cholesterol-lowering drugs. U
Zhiyu Hu believes it is possible to match nature’s highly efficient method to convert chemicals into thermal energy at room temperature, and he has data and a published paper to support his theory.
In a paper scheduled to appear in the May 18 print issue of the American Chemical Society’s Energy & Fuels, Oak Ridge National Laboratory’s Hu describes a novel method to achieve spontaneous ignition and sustained combustion at room temperature. He achieves this “nano-c
Family members need support, too
Support services provided to paramedics should also be made available to their family members if these families are to remain healthy and intact, says a University of Toronto researcher.
“Family members continue to be the primary source of nurturance and safety for those who do this high-stress job,” says Cheryl Regehr, U of T professor of social work and director of the university’s Centre for Applied Social Research. “If they don’
A study appearing in an upcoming issue of the Journal of Alzheimer’s Disease, published by IOS Press, entitled “Quantitative proteomics of cerebrospinal fluid from patients with Alzheimer disease,” may lead to a new test for diagnosing the devastating illness. About 4 million Americans suffer from Alzheimer’s disease, the most common form of dementia, characterized by memory loss and an inability to use language.
“The study identified 40 times more proteins in human spinal fluid
Women more egalitarian
When it comes to leadership in the workplace, work teams made up mostly of women tend to share leadership roles more than teams dominated by men, says a University of Toronto organizational behaviour expert.
“Women tend to prefer egalitarian norms in work groups whereas men favour hierarchical structures,” says Jennifer Berdahl, business professor at U of T’s Rotman School of Management and lead author of the study published in the March issue
As body mass index goes up, so does the risk of tearing meniscus
America’s expanding waistline is straining its knees–and pocketbook–with hundreds of thousands of overweight people undergoing surgery every year because the extra pounds they pack are leading to tears in their meniscal cartilage.
In the first major study of its kind, University of Utah School of Medicine researchers found the likelihood of tearing the meniscus, the cartilage that bears much of the load o
Project looked at massive mobile launch platform, shuttle transporter
Sandia National Laboratories recently conducted a series of tests to help NASA understand the fatigue on the space shuttle caused during rollout from the Kennedy Space Center assembly building to the launch pad – a four-mile trip.
The tests are part of NASA’s return-to-flight mission, with the first flight scheduled between May 15 and June 3.

Novel anti-cancer compounds called Enigmols suppress the growth of human cell lines representing cancers of the prostate, breast, colon, ovary, pancreas, brain and blood, and reduce tumors in three animal studies, new research shows.
In addition, Enigmols did not show side effects at effective doses, according to the research conducted at the Georgia Institute of Technology, Emory University and Wayne State University. The studies were funded by the National Cancer Institute.
A University of Central Florida researcher has uncovered an ancient protein that could be critical to stopping the uncontrolled division of tumor cells that cause cancer.
