...appendicitis, kidney stones, pneumonia, broken bones - and an X-ray alone was enough. We took care of them all just using plain films. Today, however, there's a good chance that after ordering up that plain film, the emergency doctor will send you down the hall for a second test - one that exposes you to many hundreds of times the radiation of a plain film: a CT scan. The radiation from a CT scan, or computed tomography, actually has been shown to cause cancer - quite a bit of it. A recent report, published in November in the New England Journal...
...were difficult, painful or simply impossible to see otherwise - brain tumors, spine problems, problems in the liver or lung. Nevertheless, in the '90s, CT scans were largely upstaged by the vastly more complex - but radiation-free - MRI scan. Overall, few docs would disagree that the MRI is a better test. Except for being somewhat less sharp when looking at bone, MRI is clearly more sensitive and versatile. But CT scanning has made a huge comeback in the past five years. Almost every office day of late I?ve gotten new patients who have had CT scans in the emergency room...
...receptors on the surface of brain cells, known as mGluR5 receptors (the Glu is for glutamate, a key signaling agent in the brain). They reasoned that it would be possible to correct the excesses of Fragile X by blocking these receptors, which act as accelerators of protein production. To test this idea, the researchers produced a special breed of mice that had the Fragile X trait but only half the normal number of mGluR5 receptors. The result, explains Bear: "We were able to correct the excesses [of Fragile X], taking our foot off the accelerator...
...happens, drugs that block the mGluR5 receptor already exist. Hagerman's group and a team at Rush University in Chicago are about to test one such drug, fenobam, as a treatment for Fragile X. Bear, meanwhile, has founded a company called Seaside Therapeutics that hopes to begin human safety tests of another drug as early as next year. Both researchers believe that a safe and effective mGluR5 inhibitor would help both children and adults with Fragile X Syndrome, though drug treatment early in childhood would seem to offer the most promise...
...keep it that way. Though four Chinese automakers have applied to open their own Russian plants, none have been approved, according to the Ministry of Economic Development and Trade. Indeed, there appears to be a growing backlash against Chinese manufacturers. Earlier this year, a Russian car magazine crash-tested a Chery Amulet at facilities owned by the country's biggest carmaker, OAO AvtoVAZ. The magazine, AvtoRevu, claimed the Amulet was so badly mangled in the crash that the car should be pulled from the market for safety reasons. Chery said the test was unfair...
