Inflammation and drugs to control this activity studied in a variety of tumors sites

...-grade tumors. Using anti-inflammatory medications helped protect against developing a deadly brain tumor called glioblastoma. The researchers, led by Michael Scheurer, Ph.D., postdoctoral fellow in Cancer Prevention and Melissa Bondy, Ph.D., professor of Epidemiology, both at The University of Texas M. D...

Obese people are more sensitive to pain, suggests study

... than non-obese people. "The relaxation procedure helped both groups cope with pain," said Charles Emery, the study's lead author and a professor of psychology at Ohio State University. "Additionally, our tests showed both groups had higher physical pain thresholds after the relaxation session. But the obe...

Science finds new fix for UV-damaged skin in arthritis treatment

...ers are familiar with these processes and that has helped them focus on substances - such as n-acetyl glucosamine - that are known to interrupt the UV-triggered chemical signals that turn on melanin production. Skin care products that utilize signal-blocking ingredients currently exist in the marketplace, b...

Tetracycline plus teeth equal gray smile

...new tooth whitening procedure he used on a patient helped significantly lighten these tough-to-remove stains and saved his patient more than $10,000 in dental restorative fees. He'll share this information during his discussion titled "Treating Tetracycline Staining in the Adult Dentition" to be presented a...

USC researchers investigate protein that protects tumors

...." Not only did EphB4 block those defenses, but it helped the cancer cells flourish by issuing a call for more blood vessels ?the biological equivalent of food for the tumor. "The tumor cell carrying this protein ?on its surface communicates with blood vessels nearby," Gill says. "It sends the signal for ...

Study shows hope for ridding lakes of clawed invader

...ize limits for anglers fishing Sparkling Lake, has helped establish an optimal population of the fish that routinely dine on the crayfish. The trapping on Sparkling Lake, however, has been intensive during six years with 280 traps seeded around the lake. Baited with beef liver, the traps snare both native...

Major obesity gene is 'lost in the shuffle'

...letion ?or 'knockout' ?of the ASIP gene may have helped gibbons adapt to arboreal niches. We know that the ASIP protein regulates lipid metabolism in humans, so there is certainly reason to presume that this deletion contributed to the gibbons' remarkably small body mass, enabling them to thrive in the j...

New potential drug target in tuberculosis

...the active site of LipB bound to a lipid inhibitor helped to determine the function of the enzyme. In collaboration with EMBL's Proteomics Core Facility in Heidelberg and researchers from the University of Illinois (USA), the Hamburg group discovered how LipB attaches specific fatty acids onto other protein...

New pathways for autoimmune treatment identified

...t of diseases from type 1 diabetes to alopecia has helped explain the imbalance of immune regulator and killer cells in autoimmune disease. Mutation in the Aire gene causes APS1, a disease causing two out of three problems ?an underactive parathyroid, yeast infection of the skin and/or mucous membrane and...

Super-sized cassava plants may help fight hunger in Africa

...he production of cyanide. In previous work, Sayre helped create cassava that produced little to no cyanide once it is harvested. He is also the principal investigator of an ongoing project focused on improving the nutritional content of cassava. In this work Sayre leads a team of national and internationa...

Viagra improves high altitude exercise performance up to 45% for some

...cyclists at high altitude, mostly because the drug helped some participants improve a lot -- up to 45% -- while others showed little change. Sildenafil provided no benefit at sea level. Ten cyclists who took sildenafil at altitude collectively lowered the time it took to cover six kilometers by 15% compare...

NASA technology helping injured US troops

...he SAM walker prevented my knees from buckling and helped me regain my mobility. I was able to graduate to the therapy on the parallel bars a lot quicker as a result," said Geddis. "NASA's technology in the walker's harness gave me the stability to do squats and knee raises I could never do before." Phys...

Johns hopkins researchers find link between cell's energy use and genome health

...o other molecules in a series of biochemical steps helped along the way by enzymes that make each step happen faster. Focusing on two of these enzymes, closely related to each other, the research team separately removed each from the yeast cells to see if either or both were essential to the cell's surviv...

MIT 'seeing machine' offers hope to blind

...zalez (S.B. 2003) and Shima Rayej (S.B. 2004), who helped design and construct the seeing machine. "We essentially made the new machine from scratch," Goldring said. While still allowing the projection of images, video and more onto a person's retina, the new desktop device costs much less than its predece...

Scientists aim to thwart use of flu as bioweapon

...provement is due to early mathematical models that helped scientists and physicians understand and target the disease more effectively. "How flu infects the body and how the body responds to a flu infection is not understood completely," said Wu. "Mathematical models will help guide flu experts to ask the ...

Brazil creates buffer zone around coral reefs off Atlantic coast

Under the government declaration, oil and gas activities are prohibited in 75 percent of the buffer zone, and approval for such development in the other 25 percent would require detailed ...

Protein-coated dental implants could improve bone regeneration

...ce for new tissue to grow into." The experiments helped researchers narrow down possible treatments to the use of proteins that directed stem cells to become bone-forming cells. Those proteins ?called bone morpheonetic proteins ?have already shown promise as a regeneration therapy for craniofacial reconst...

UN review shows need to halt destructive fishing practice

Tyrannosaur survivorship -- tough times for teens

A massive dinosaur death bed in Alberta has helped map out the animal's life span and thrown doubt on long-held theories about how one species lived, says new research conducted in part at the University of Alberta. "One of the surprises to me was that the overall pattern of survivorship fits close...

Federal testing for mad cow disease a failure, law review editor says

The Bush administration's approach to safeguarding the nation's supply of beef has been to deny that there's a problem and to resist comprehensive BSE testing, Gregory L. Berlowitz, an editor at the University of Illinois Law Revi...
