Miniature implanted devices could treat epilepsy, glaucoma

... said. Rickus has developed a "living electrode" coated with specially engineered neurons that, when stimulated, releases the neurotransmitter to inhibit the seizure. The engineered neurons are living tissue stimulated with a microchip. Rickus and Irazoqui have shown that a certain amount of electrical ...

...5 millimeters) thick. The windows inner surface is coated with a phosphor film 10 microns thick, bringing the overall thickness of the lamp structure to 800 microns. Flat panels with radiating areas of more than 200 square centimeters have been fabricated, Park said. Depending upon the type of gas and phosp...

Students devise oral quick-dissolve strips for rotavirus vaccine

...o swallow the vaccine. The dissolved medication is coated with a material to protect it in the childs stomach. This coating is also designed to release the vaccine in the small intestine, where it should trigger an immune response to prevent a rotavirus infection. The novel drug-delivery system is needed...

ENDEAVOR III Trial reports key findings on new-generation stent

...& Johnson, Miami Lakes, FL). The Endeavor stent is coated with zotarolimus, a medication that, like the Cyphers sirolimus coating, reduces renarrowing of the artery by preventing the growth of scar tissue inside the stent. Initial data showed that procedural success was higher with the new Endeavor stent...

Off-label and untested use of drug-coated stents appears widespread

... newer drug-eluting stents are normal metal stents coated with a drug that is known to interfere with the process of restenosis (re-obstruction). Data on the use of drug-eluting stents outside of approved indications in real-world settings are limited, according to background information in the articles. ...

Mayo Clinic study shows drug-eluting stent use in heart patients determined more by insurance type

...d by the FDA. The metal of a drug-eluting stent is coated with a drug that helps prevent tissue regrowth that can block the vessel. Studies have shown that drug-eluting stents lower the need for repeat procedures to fewer than 10 percent of cases when they are used for FDA-approved conditions in coronary ar...

Study finds coronary procedure adds no benefit over 'optimal medical therapy' alone

...ted artery. Because drug-eluting stents, which are coated with medications that help prevent scarring, were .... But studies have shown little difference between coated and non-coated stents in their ability to prevent heart attacks and deaths. At a median follow-u...

Emory algorithm improves kidney transplant chances for sensitized patients

The beads are mixed with the recipient's blood and placed in a flow cytometer. A laser reads which antibodies, if any...

Scientists create dual-modality microbeads to improve identification of disease biomarkers

... beads are washed with ethanol. Then the beads are coated with a polymer that creates a hydrophilic surface on the beads. This allows the beads to be functionalized by adding antibodies or DNA molecules to the surface that will capture the target molecules. These beads are dual-function -- both optical an...

Picture this: FSU professor's research could lead to vastly improved medical imaging

...onth of a meter in depth. But if a CD instead was coated with Fe8, the Fe8 film would be only about a nanometer one-billionth of a meter deep. This could increase our ability to store data in smaller and smaller spaces." It also could lead to significant breakthroughs in the area of quantum computing, wh...

Concentrations of certain toxins in breast milk are low, study finds

... space, and the gases were collected with a needle coated with absorbent material. The researchers collected indoor air samples by passing air through a material that specifically absorbed the VOCs of interest. Once they collected the VOCs, the researchers used gas chromatography-mass spectrometry to anal...

MIT implant could measure tumor growth, treatment

...detection nanoparticles composed of iron oxide and coated with a sugar called dextran. Antibodies specific to the target molecules are attached to the surface of the particles. When the target molecules are present, they bind to the particles and cause them to clump together. That clumping can be detected b...

SCAI president testifies before FDA on safety of drug-eluting stents

...hich prop open narrowed arteries in the heart, are coated with a medication that prevents the build-up of scar tissue inside the stent. Drug-eluting stents have proven so successful in preventing renarrowing of the artery or restenosis they were being used in 80 to 90 percent of stent procedures, thereby ...

New bird flu drug promises to beat the problem of resistance

... How it works The flu virus is like a football coated with two different types of enzymes. These are proteins which carry out specific jobs for the virus. The first of these proteins, haemagglutinin (H), helps the virus to invade cells in the throat whilst the second, neuraminidase (N), allows the new...

Sandia work launched on space shuttle shows live cells influence growth of nanostructures

...that discourages unwanted biofilm formation on the coated surface - important for avoiding infections that could be carried by implants and catheters. The cell's ability to sense and respond to its environment is what forms these unique nanostructures, says Brinker. During spin-coating, the cells react to...

Stopping medication too soon after receiving a drug-eluting stent raises risk of death

...tent thrombosis with bare-metal stents (stents not coated with a drug) decreases rapidly after two to four weeks, and patients typically need thienopyridines for only about one month. In comparison, with drug-eluting stents the risk of stent thrombosis lasts for a longer period of time and patients with DE...

New contrast agents may be on horizon for better medical imaging

...to even smaller particles. Next, they successfully coated the particles with dextran, a naturally occurring carbohydrate. The chemical coating -- which Watkin compares to the thin, outer shell of an M&M candy -- functions as a spacer, preventing the nanoparticle from undergoing a chemical reaction when it ...

Turning the tables on drug discovery

Developing new drugs in this way is much faster than using conventional screening. It is also possible to reduce the side effects of conventionally-developed drugs...

Complex artery disease best treated with simple approach

...n after treatment. The use of drug-eluting stents coated with medicine to keep the artery from re-narrowing has improved the outcome of this kind of procedure, but the optimal method to treat bifurcation lesions has not been established. This study examined two ways of treating severe diseased arteries: b...
