UCLA study uncovers clues for why Graves' disease attacks the eyes

...de. In extreme cases, patients experience trouble closing their eyelids, severe double vision, corneal scarring, optic nerve damage and even blindness. Graves?disease is nine times more common in women than men. The disorder most often strikes during the childbearing years, and runs an average course ...

Study uncovers a lethal secret of 1918 influenza virus

...ght into how the virus that swept the world in the closing days of World War I was so efficiently deadly, claiming many of its victims people in the prime of life. The work suggests that it may be possible in future outbreaks of highly pathogenic flu to stem the tide of death through early intervention. T...

Scientists uncover new target in cancer mutation puzzle

...by two well-known cancer genes, p53 and Ras. By closing in on this deadly collaboration, researchers showed for the first time why some molecules such as Rho are targeted by cancer genes ?and how they might lead to a promising way to intervene against cancer. "We have very little understanding of how ...

Breathing easy: When it comes to oxygen, a bug's life is full of it

...en, they can live a long time without breathing by closing their spiracles and curbing their activity. “Insects are able to survive hypoxic environments,?explained Kirkton, the symposium chairman. “They can shut down and survive for hours or days. They have a low metabolic rate and can close their spiracl...

'GreeneChip' -- New diagnostic tool that rapidly and accurately identifies multiple pathogens

...rned to New York City from West Africa resulted in closing a hospital emergency room. For example, one of the children died of cardiac failure caused by plasmodium falciparum (malaria). Therapeutic options for treatment of VHF are limited; however, rapid isolation if infected persons is critical to curb co...

Giant insects might reign if only there was more oxygen in the air

...a larger body. Insects can limit oxygen flow by closing their spiracles. In fact, one reason insects are so hardy is that they can close their spiracles and live off the oxygen they already have in their tracheae. Kaiser recalled a caterpillar that fell into a bucket of water in his lab. When the creature...

Leading reason for corneal transplants comes into focus

...painstaking process of elimination, but now we are closing in on the gene that causes what we believe is the most widespread form of Fuchs, not just the rare types in individual families. Our methods have clearly shown that Fuchs is not just one disease, but rather a disorder with several genetic flavors." ...

...y creating holes in the muco-adhesive or indeed by closing the holes. Moreover, by selecting different shapes, which owing to their compact size can achieve high degrees of friction, the device can be made smaller. The researchers are currently building a prototype that will be tested in living pigs. We mu...

UCSD study reveals how plants respond to elevated carbon dioxide

Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic

...such as by travel restrictions, quarantine or even closing schools), but we find that these measures are useful in buying time to produce and distribute sufficient quantities of vaccine and antiviral drugs," said Germann of Los Alamos' Applied Physics Division. "Based on our results, combinations of mitigat...

African amphibians make extreme parental sacrifice: The skin off their backs

...against their mothers while repeatedly opening and closing their mouths. They used their lower jaws to lift and peel the outer layer of the mother's skin." Studies of the females' skin revealed that the outer layer is up to twice as thick in brooding females as in non-brooding females and is full of nutriti...

Both alcoholism and chronic smoking can damage the brain's prefrontal cortex

...uch as bending the elbow and wrist and opening and closing the hand, while the new arm will be capable of about 20 different movements, including moving fingers independently, says Clark. Existing prosthetic arms typically are controlled by signals from an intact muscle, such as a shoulder shrug, so only o...

Mechanism for memory revealed in neurons of electric fish

... it's kind of like they are opening their eyes and closing them," says Zakon. "Each pulse of electricity is a snapshot of the environment. These guys are swimming around and discharging at a very regular frequency. They're digitizing their environment." But a problem occurs when the fish are close to each o...

Access to existing medical treatments could save more lives than spending to improve the treatments

...ditional lives by making a better drug and without closing the gap in care -- delivering the better drug to only 60 percent of eligible patients -- the drug's lowering of mortality would have to be increased from 20 percent to 33 percent. Woolf calls this the "break-even point" and notes that it is an unreal...

New technique helps researchers determine amino-acid charge

...ning helices underlie the mechanism of opening and closing of the nicotinic receptor ion channel. The data, Grosman said, indicate that such rotation is minimal, if any. ...

Changes to embryos can elicit change in adult fish

...-lever and two in-levers. "We found that as the closing in-lever gets longer, the out-lever gets shorter and vice-versa," explained Streelman. "When the in-lever is long, this gives the jaw a high mechanical advantage and the jaw can produce more force for biting. When the out-lever is long, that result...

Team led by Carnegie Mellon University scientist finds first evidence of a living memory trace

...r activity using dyes sensitive to the opening and closing of calcium channels on neurons. The scientists created an imaging grid across the glomeruli and measured the ratio of fluorescence versus nonfluorescence over time. Galán then used advanced mathematical techniques to process the images and create a ...
