Test may allow patients to avoid costly and time-consuming CT scans
A new study shows that the CA125 blood test, which measures the level of protein produced by ovarian cancer cells in the blood, may be superior to standard imaging techniques like CT scans in predicting survival in patients with recurrent ovarian cancer. The study, to be published online September 13 in the Journal of Clinical Oncology, is the first to compare the two procedures with respect to survival.

Challenging decades of scientific belief that the decoding of sound originates from a preferred side of the brain, UCLA and University of Arizona scientists have demonstrated that right-left differences for the auditory processing of sound start at the ear.
Reported in the Sept. 10 edition of Science, the new research could hold profound implications for rehabilitation of persons with hearing loss in one or both ears, and help doctors enhance speech and language development in hearin
In recent years, scientists have made important strides in developing drugs that help patients manage the symptoms of Parkinson’s Disease – a chronic, progressive movement disorder affecting as many as one million Americans. But despite their effectiveness, the drugs don’t stop Parkinson’s disease from progressing, causing patients’ symptoms to eventually grow worse in spite of medication.
Now, researchers at Cedars-Sinai Medical Center have found that two spec
USC study in NEJM signals likely future health problems
By age 18, the lungs of many children who grow up in smoggy areas are underdeveloped and will likely never recover, according to a study in this week’s issue of the New England Journal of Medicine.
The research is part of the Children’s Health Study, the longest investigation ever into air pollution and kids’ health. Between 1993 and 2001, study scientists from the Keck School of Medicine of the Universi
Within just 10 minutes of meeting, people decide what kind of relationship they want with a new acquaintance, a recent study suggests.
The research, conducted with college freshmen who met on the first day of class, found that these snap judgments influenced what kind of relationships actually did develop.
While the power of first impressions has been well known, this research shows that the course of a relationship may be influenced much more quickly than was once believe
A new study on liver transplants necessitated by the hepatitis C virus (the most common indication for this type of transplant) found that long-term outcomes are similar to patients receiving transplants due to other diseases. It was the first study to examine long-term transplantation results in hepatitis C patients and to identify risk factors that might lead to transplant failure or death.
The results of this study appear in the September 2004 issue of Liver Transplantation, the
A report released today at the international Greenhouse Gas Control Technologies Conference in Vancouver concludes that geological conditions in the Weyburn oil field in western Canada are favourable for long-term storage of carbon dioxide (CO2). The four-year, multidisciplinary study was conducted by the Petroleum Technology Research Centre (PTRC) in Regina under the auspices of the International Energy Agency Greenhouse Gas (IEA GHG) Research and Development Programme.
The PTRC w
In the first study of its kind, researchers at the Temple University School of Medicine will analyze whether the frequent monitoring and adjustment critical to the management of diabetes during pregnancy can be better accomplished virtually. The ultimate goal is to reduce large birth weights, which can pave the way to later problems such as obesity and diabetes.
Gestational diabetes, which typically occurs toward the end of pregnancy, affects 3 to 5 percent of all women in the United Stat
A drug that is already being tested as an anticancer agent, especially in lymphoma, may also reduce the kidney disease that is a result of systemic lupus, according to a researcher at Wake Forest University Baptist Medical Center.
The drug, SAHA (suberoylanilide hydroxamic acid ), inhibited the onset of lupus-related kidney disease in mice with lupus, said Nilamadhab Mishra, M.D., an assistant professor of internal medicine – rheumatology, writing in the Sept. 15 issue of The Journa
Hospital costs for severe cases down $100M per year since shot introduced
The chicken pox vaccine has saved America hundreds of millions of dollars since its introduction in 1995 by preventing the kinds of severe cases that used to send children, teens and adults to the hospital, a new study finds. In fact, it’s even more effective — and cost-effective — than originally predicted at preventing hospitalizations and hospital costs.
And the widespread immunity to the dis
When it comes to making noise, both parrots and humans rely on extremely specialized vibrating organs in their throats. Now scientists at Indiana University and Leiden University in The Netherlands have shown for the first time that parrots, like humans, also can use their tongues to craft and shape sound.
“This is the first direct evidence that parrots are able to use their large tongues to change the acoustic properties of their vocalizations,” said IU Bloomington neurologist Roder
Up to 37 percent of adults experience mood disorders at some point in their lives; and many receiving treatments may undergo adverse dental side effects according to a study that appears in the September/October 2004 issue of General Dentistry, the Academy of General Dentistry’s (AGD) clinical peer-reviewed journal.
Mood disorders are a group of mental conditions, including depression and bipolar disorder, which are common among adults and early diagnosis and treatment can gr
Accepting a fact as scientific is not a simple matter of whether the methodology is sound – what matters is whether the science that underpins it is compatible with our stereotypes and prejudices.
That is the key finding of a new study produced as part of ESRC research into social identity and discrimination by Professor Alex Haslam, of the School of Psychology, University of Exeter.
Professor Haslam and Dr Michelle Ryan, also at Exeter, analysed reactions to previous res
The bands of ancient Neanderthals that struggled throughout Europe during the last Ice Age faced challenges no tougher than those confronted by the modern Inuit, or Eskimos.
That’s the conclusion of a new study intended to test a long-standing belief among anthropologists that the life of the Neanderthals was too tough for their line to coexist with Homo sapiens. And the evidence discounting that theory lies with tiny grooves that mar the teeth of these ancient people.

Research shows hormone can restore reproductive function, suggests role in treating infertility, eating disorders, bone loss
A new study has found that leptin plays a critical role in women’s reproductive and neuroendocrine health and suggests a future for the hormone in treating a number of conditions including exercise-induced bone loss, eating disorders and some cases of infertility. Led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and Massachusetts General Hospital
A study by researchers from the University of Southampton and the Medical Research Council (MRC) has shown that lower rates of growth in the womb and higher weight gain in the first weeks after birth could predispose individuals to chest illnesses in later life.
The research suggests that improving a baby’s lung growth and development before and after birth could have lifelong benefits for its respiratory health.
The collaborative study, by a team from the Universi
