Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses

...aced alongside the endoscope allow surgeons to cut away inflamed tissue and polyps, clearing a path for the sinuses to drain normally. Lane says that if left untreated, polyps can lead to severe blockage and recurring infections. All patients were monitored for a minimum of nine months to see if poly...

A new approach to growing heart muscle

... Research Part A. And while BEHM is still years away from use as a human heart treatment, or as a testing ground for new cardiovascular drugs, the U-M researchers say their results should help accelerate progress toward those goals. U-M is applying for patent protection on the development and is active...

'Erectile dysfunction' drugs heighten natural anti-cancer activity

... a specialized cell that diverts the immune system away from tumors, allowing swarms of cancer-attacking T-cells to migrate to tumor sites in the rodents. Lab-grown cancer cells treated with sildenafil showed similar results, as did tissue samples taken from 14 head and neck cancer and multiple myelom...

Sports cheats beware -- new test detects previously undetectable drug

...d mean that athletes will no longer be able to get away with this form of cheating," says lead author Mario Thevis, who works in the Center for Preventive Doping Research ?Institute of Biochemistry, at the German Sport University Cologne in Germany....

Teenager moves video icons just by imagination

...aders game to both help the patients pass the time away and garner some very useful, pioneering data. Computer science and engineering master's degree candidate Tim Blakely pulled several all-nighters to program the game into the ECoG system. "Doing this is a win-win situation , both for science and the c...

Key to lung cancer chemo resistance revealed

...In cancer cells, NRF2 activity runs amok, sweeping away all cellular toxins, including chemotherapy agents. Biswal says that blocking NRF2 activity could improve the effectiveness of standard chemotherapy drugs, particularly platinum-based compounds widely used for lung cancer. In Biswal's study, ha...

New system could drastically reduce herbicide use

.... "If he sees a weed, he can actually tell how far away it is." An on-board computer offers access to information that provides the morphological features of plants, to help the robot determine just what is and isn't a weed. Once a weed is identified, a robotic arm attached to the front of the machine...

A new target for painkillers

... paw with a blunt Teflon tip before the rat pulled away the paw. Normal rats could withstand 4.7 times more pressure before withdrawing their paws, compared with rats with sciatica. When cone snail toxin RgIA was injected, the rats with sciatica were able to tolerate a stronger touch from the tip ?both...

Biodegradable napkin -- featuring sensitive nanofibers -- may quickly detect biohazards

...he contaminant. "We're probably still a few years away from having this ready for the real world," Frey said, "but I really believe there is a place for this type of product that can be used by people with limited training to provide a fast indication of whether a biohazard is present." ...

Some butterflies travel farther, reproduce faster

...le fritillary butterflies that allows some to move away from their birth place and establish new colonies. These venturesome butterflies are stronger fliers and reproduce more quickly compared to their less mobile female relatives. The study is a window to how genetic differences influence behavior and h...

Nanoparticle assembly enters the fast lane

...orces interacting linker segments of DNA to extend away from the gold surface, allowing for more efficient assembly. "By using properties of DNA, we can increase assembly kinetics, or speed, by relatively simple means without a lot of synthetic steps," Maye said. The research team probed the synth...

An artificial cornea is in sight, thanks to biomimetic hydrogels

...nlays, some of the epithelial layer can be scraped away and replaced with a hydrogel contact lens. The lens becomes biointegrated when clear epithelial cells grow over the top of the inlayed lens. Inlays offer an advantage over LASIK surgery, which works but isn't reversible, Myung says. He envisions im...

Successful lung cancer surgery not enough to break nicotine dependence in many smokers

...tance from the medical community to help them stay away from cigarettes, and that this intervention should begin as soon as possible after treatment," Walker said. No such programs are currently offered to lung cancer surgery patients, he added. At least seven studies of non-small cell lung cancer pati...

Biologists probe the machinery of cellular protein factories

...d out by ribosomes, tiny protein factories humming away inside the cells of all living things. Harry Noller, the Sinsheimer Professor of Molecular Biology at the University of California, Santa Cruz, has been studying the ribosome for more than 30 years. His main goal is to understand how the ribosome w...

New dyslexia theory blames 'noise'

..., information is often redundant and dyslexics get away with the perception deficit," Ziegler said in an e-mail. "In noise, however, they can no longer compensate. "What is important is that noisy environments are the rule and not the exception," he added, citing a study from South Bank University in t...

Wild tigers need cat food

...age of 23 percent of the park’s tigers either move away or die each year from either naturally or from poaching outside of the park, yet total numbers remained high. "This study shows that even well-protected wild tiger populations have naturally high rates of annual losses, and yet do fine because of ...

Scientists get best look ever at water-life connection

...n while it was immersed in water revealed that far away from the protein -- in a region Zhong called "bulk water" -- the water molecules were flowing around each other at their typically fast speeds, with each movement requiring only a single picosecond. But the water near the protein formed several dist...

Two-faced protein can stop metastasis or promote it, researchers say

...mesenchymal cadherins allows cancer cells to break away from tissue and spread. They found that p120 "prefers" to bind to E-cadherin, rather than to mesenchymal cadherins. So in normal epithelial cells p120 always associates with the more abundant E-cadherins. But when E-cadherin production is lost duri...

Psst! Coffee drinkers: Fruit flies have something to tell you about caffeine

...dy, Montell and his colleagues kept 50 fruit flies away from food overnight and for breakfast gave the starved flies 90 minutes to eat as much as they wanted of either or both of two concoctions: a blue-colored mixture of sugar and agar and a red-colored mixture of caffeine, sugar and agar. The researcher...

How ants find their way

...ylinder and the ants searched for the food at 20cm away where the retinal size of the landmark was the same." To analyse the ants' powers of recall an ambiguous situation was set up. Ants were trained to search for food between two cylinders of different sizes and then tested with the training cylinders...
