Obsessing over strep throat in kids

2010-10-21
A common infection in children, strep throat can lead to problems with a child's heart, joints or brain if left untreated. And when the brain is involved, motor and mental functioning may be compromised, leading to syndromes such as attention deficit disorder and obsessive-compulsive disorder (OCD). While scientists have speculated on a link between OCD and childhood infections like strep for more than two decades, Prof. Daphna Joel and her team of researchers at Tel Aviv University's Department of Psychology have now scientifically demonstrated that strep can lead to ...

Frontal lobe of the brain is key to automatic responses to various stimuli, say scientists

Frontal lobe of the brain is key to automatic responses to various stimuli, say scientists
2010-10-21
(Santa Barbara, Calif.) –– Some people may excel at riding a bike, tying a tie, or playing the piano, but those same people may find it difficult to explain or teach those skills to someone else. These motor skills are learned in one part of the brain, whereas classroom instruction and information read in a book are acquired in another area of the brain, explained F. Gregory Ashby, professor and chair of UC Santa Barbara's Department of Psychology. This second area of learning is the frontal cortex –– the area immediately behind the forehead –– where executive function ...

Harm reduction cigarettes can be more harmful than conventional brands, researchers report

Harm reduction cigarettes can be more harmful than conventional brands, researchers report
2010-10-21
RIVERSIDE, Calif. – To reduce the toxicity of cigarette smoke, tobacco companies have introduced "harm reduction cigarettes," often marketed as safer than conventional brands. But stem cell scientists at the University of California, Riverside have found that even sidestream smoke (which burns off the tip of a cigarette) from harm reduction cigarettes impairs growth of human embryonic stem cells more than sidestream smoke from a conventional brand. "Harm reduction products are not necessarily safer than their conventional counterparts," said Prue Talbot, the director ...

A redeeming role for a common virus

2010-10-21
Washington, DC – A common virus that can cause coughing and mild diarrhea appears to have a major redemptive quality: the ability to kill cancer. Harnessing that power, researchers at Georgetown Lombardi Comprehensive Cancer Center, part of Georgetown University Medical Center, are conducting a clinical trial to see if the virus can target and kill certain tumor types. By the age of five, most people have been exposed to the virus, called reovirus. For some, it can trigger brief episodes of coughing or diarrhea while many other don't develop any symptoms. The body ...

Estrogen replacement therapy speeds ovarian cancer growth, new study reports

2010-10-21
Aurora, Colo. (Oct. 19, 2010)— Estrogen therapy used by menopausal women causes a type of ovarian cancer to grow five times faster, according to a new study by researchers at the University of Colorado Cancer Center. Menopausal estrogen replacement therapy (ERT) also significantly increases the likelihood of the cancer metastasizing to the lymph nodes, according to the study, which will be published in the Nov. 1 issue of Cancer Research. The study was released online Oct. 19, 2010. Cancer Research, published by the American Association for Cancer Research, is the world's ...

Climate change may create tipping points for populations, not just species

Climate change may create tipping points for populations, not just species
2010-10-21
As Earth's climate warms, species are expected to shift their geographical ranges away from the equator or to higher elevations. While scientists have documented such shifts for many plants and animals, the ranges of others seem stable. When species respond in different ways to the same amount of warming, it becomes more difficult for ecologists to predict future biological effects of climate change--and to plan for these effects. In a study published this week in the journal Nature, University of Wyoming ecologist Daniel Doak and Duke University ecologist William ...

Discovery of a mechanism that controls the expression of a protein involved in numerous cancers

2010-10-21
Researchers at the Institute for Research in Immunology and Cancer (IRIC) of the Université de Montréal have identified a new mechanism controlling the transmission of an abnormal signal at the origin of several cancers. In an article published in the journal Cell, Marc Therrien's team explains the recent discovery of a protein complex that controls the RAS/MAPK signalling pathway, responsible for some of the deadliest cancers, including pancreatic, colon and lung cancers, and melanomas. This regulating mechanism could prove to be a promising therapeutic target for the ...

3 NASA satellites capture Typhoon Megi strengthening again

3 NASA satellites capture Typhoon Megi strengthening again
2010-10-21
Three NASA satellites are keeping tabs on Typhoon Megi and noticed that it was strengthening in the South China Sea today, but increasing wind shear may again weaken the system over the next couple of days. NASA's TRMM, CloudSat and Aqua satellite captured images of Megi's clouds, rainfall and eye as they passed over the storm and saw clouds higher than 9 miles filled with ice, creating heavy rainfall. The Tropical Rainfall Measuring Mission (TRMM) satellite passed over Typhoon Megi from its vantage point in space on October 18 at 2321 UTC (7:31 p.m. EDT) and saw that ...

GOES-13 sees system 99L organizing tropically
2010-10-21
The GOES-13 satellite keeps a continuous eye over the eastern U.S., the Caribbean Sea, Gulf of Mexico and Atlantic Ocean, and noticed that System 99L is much better organized today, October 20, hinting that it could become a tropical depression later today. At 8 a.m. EDT on Wednesday, October 20, System 99L, a low pressure system about 150 miles southwest of Grand Cayman appears to be getting organized as it drifts eastward in the Caribbean Sea. System 99L is showing more organization than it did yesterday, despite strong upper-level winds that are currently inhibiting ...

New search method tracks down influential ideas

New search method tracks down influential ideas
2010-10-21
Princeton computer scientists have developed a new way of tracing the origins and spread of ideas, a technique that could make it easier to gauge the influence of notable scholarly papers, buzz-generating news stories and other information sources. The method relies on computer algorithms to analyze how language morphs over time within a group of documents -- whether they are research papers on quantum physics or blog posts about politics -- and to determine which documents were the most influential. "The point is being able to manage the explosion of information made ...

Magic tricks reveal surprising results about autism

2010-10-21
Magicians rely on misdirection—drawing attention to one place while they're carrying out their tricky business somewhere else. It seems like people with autism should be less susceptible to such social manipulation. But a new study in the U.K. finds that people with autism spectrum disorder are actually more likely to be taken in by the vanishing ball trick, where a magician pretends to throw a ball in the air but actually hides it in his hand. In the vanishing-ball illusion, a magician throws a ball in the air a few times. On the last throw, he merely pretends to throw ...

Exploring Africa's success stories

2010-10-21
Conventional wisdom has long been negative on Africa. Historically, it has been seen as a failing continent, plagued by deep-rooted problems — poverty, corruption, war, and disease. But after four decades of relative stagnation, Africa has been growing rapidly. Since the 1990s, many African countries have seen economic and political improvements, more transparent elections, increased democracy and freedom of press. But these successes are not well understood. In 2007, the National Bureau of Economic Research (NBER), the leading nonprofit economics research organization ...

Burn injuries rapidly deplete vitamin E

2010-10-21
CORVALLIS, Ore. – Severe burn injuries in children have been shown to rapidly deplete the levels of vitamin E in their body's adipose, or fat tissues, a new clinical study has found. Stored levels of this important antioxidant were reduced more in a few weeks than might normally be possible in years. An analysis of eight children with third-degree burns over much of their body found they lost almost half of their stored vitamin E in three weeks, even though they were being given about 150 percent of the recommended daily allowance of vitamin E and other nutrients in ...

Coral algae (symbiodinium) discovered in black corals at never seen before depths

Coral algae (symbiodinium) discovered in black corals at never seen before depths
2010-10-21
Researchers at the Hawai'i Institute of Marine Biology (HIMB), an organized research unit in the University of Hawai'i at Mānoa's School of Ocean and Earth Science and Technology have made a remarkable new discovery. When most people envision coral, they typically think of shallow-water reef-building corals found along beaches and tropical nearshore habitats. These "typical" corals are dependent upon photosynthetic algae (also known as Symbiodinium or zooxanthellae) found in their tissues to obtain nutrients to live off of. In deeper less known waters, closely related ...

Conventional, annual Pap smear cost-effective follow-up after cervical lesion treatment

2010-10-21
(SACRAMENTO, Calif.) — A study of the options for reducing cancer incidence and mortality among women who have been treated for precancerous cervical lesions found that an annual conventional Pap smear is a cost effective strategy. Joy Melnikow, professor in the Department of Family and Community Medicine and colleagues tested several follow-up screening strategies for the 500,000 American women diagnosed and treated for cervical intraepithelial neoplasia (CIN), abnormal cervical cell growth that can lead to cervical cancer. The first comprehensive study of its kind, ...

A University of Washington Medical Center patient on Thursday, Oct. 21, will be the world's first recipient of a device that aims to quell the disabling vertigo associated with Meniere's disease. The UW Medicine clinicians who developed the implantable device hope that success in a 10-person surgical trial of Meniere's patients will lead to exploration of its usefulness against other common balance disorders that torment millions of people worldwide. The device being tested – a cochlear implant and processor with re-engineered software and electrode arrays – represents ...

Virtual colonoscopy option could improve colorectal cancer screening rates, patient survey suggests

2010-10-21
Providing computed tomography colonography (CTC) — otherwise known as virtual colonoscopy — as an alternative to conventional colonoscopy could improve colorectal cancer (CRC) screening rates, according to a study in the November issue of the American Journal of Roentgenology (www.ajronline.org). CRC is the second leading cause of cancer in the U.S. "While colonoscopy is currently the preferred test for CRC screening, the invasive and time-consuming characteristics of the test are often cited as reasons for noncompliance with screening," said Fouad J. Moawad, lead author ...

Virtual colonoscopy and teleradiology bring colorectal cancer screening to patients in rural areas

2010-10-21
Computed tomography colonography (CTC) — otherwise known as virtual colonoscopy — is feasible in remote health centers where optimal colonoscopy is limited, according to a study in the November issue of the American Journal of Roentgenology (www.ajronline.org). The study was performed at Fort Defiance Indian Hospital in Fort Defiance, AZ, and Tuba City Regional Health Care Center in Tuba City, AZ, both of which are rural medical centers serving Native American, mainly Navajo, populations. After brief on-site instruction, including performing a CTC examination on a volunteer ...
