...ide for the patient," Afshari warns. "We carefully screen each candidate and educate them about the lifetime commitment involved with the keratoprosthesis. Patients require a lot of follow up to make certain the artificial cornea remains structurally sound and healthy." Because the artificial cornea is a f...

Researchers develop rapid diagnostic tool for pathogen identification

...orm, called “Mass Tag PCR,?that can simultaneously screen for multiple infectious agents. The new technology is addressed in a paper published in the February issue of the Centers for Disease Control and Prevention's (CDC) Emerging Infectious Diseases.

First real-time view of developing neurons reveals surprises, say Stanford researchers

...in that respond to images. Niell set up a tiny LCD screen showing squares the size of the fish's favorite planktonic food moving up and down or left and right. They expected to find that young neurons fire in response to a variety of different images, then refine their role over time so that in the adult f...

Purdue proves concept of using nano-materials for drug discovery

...ch an advanced technology could be used to quickly screen millions of untested drug compounds that exist in large pharmaceutical "libraries." The chips could dramatically increase the number of experiments that are possible with a small amount of protein. "It's been very hard to study these proteins becaus...

...ews of the ocean. Clark can move a cursor around a screen and listen-in on different parts of the world. If he hears a whale singing, he can fix its location and position it in space and time and observe multiple animals that are 100’s of miles apart—cohorts of humpback singers moving coherently?and watch t...

HIV Patients May Be at Risk of Heart Problems When Taking Protease Inhibitor Drugs

...ely, Drs. Ackerman and Badley say. The first is to screen by electrocardiogram for heart effects in vulnerable patients. The second is to be alert for multiple drug therapy situations, because certain drug-drug combinations could trigger the adverse heart side effects. Background of the Discovery Dr. Badl...

New Technique for Tracking Gene Regulators

...n of nerve cells. But there has been no easyway to screen the entire genome. “We are the first to do a genome-widesurvey,?says Dunn.The problem has been the sheer magnitude of information in the genome:three billion nucleotides, and many tens of thousands genes. Trying toascertain which of these genes CREB ...
