The researchers then eliminated the galactose, causing the first ...New method may accelerate drug discovery for difficult diseases like Parkinson's
... brains, including death due to toxic overproduction of alpha-synuclein. Once the cyclic peptides were inserted into the model yeast cells, Kritzer switched the yeast into Parkinson's mode and waited to see which yeast cells survived. Of the approximately 5 million yeast cells that were inserted with a ...Israeli scientists show bacteria can plan ahead
... and found that, in addition to the genes that enable it to digest lactose, the gene network for utilizing maltose was partially activated. When they switched the order of the sugars, giving the bacteria maltose first, there was no corresponding activation of lactose genes, implying that bacteria have ...Baseline Research Indicates High Interest in Centocor-Ortho Biotech's SIMPONI(R)
... reported that close to 40% of their severe RA patients could be considered candidates for SIMPONI and that the majority of SIMPONI patients would be switched from other biologic agents. Market share projections suggest that SIMPONI will primarily draw from other TNF-inhibitors and 38% of the respondents ...MIT: New method could lead to narrower chip patterns
... CAMBRIDGE, Mass.--Researchers at MIT have found a novel method for etching extremely narrow lines on a microchip, using a material that can be switched from transparent to opaque, and vice versa, just by exposing it to certain wavelengths of light. Such materials are not new, but the researchers ...A molecular ripcord for chemical reactions
... Systems (ICMS) and the Department of Chemical Engineering and Chemistry, both at TU/e, is the first to have demonstrated that a catalyst can be switched from a dormant to an active state (see illustration) by pulling on a polymer chain, a "molecular ripcord." The researchers were able to use this ...Frost & Sullivan Applauds SHL Telemedicine for Excellence in Product Innovation
... This full 12 lead ECG personal digital cellular transmitter is a monitoring system that uses either cellular network (GPRS) or public switched telephone network (PSTN) to transmit real-time medical cardiological data remotely. It effectively fulfils the need for an end-user friendly system. ...Anti-cancer gene discovered: Perspective for therapy
... cancer in all three. Reciprocally, switching off the gene leads to cancer. The scientists think there is a good chance that the gene can be switched on again with a drug. They report their findings in the reputed scientific journal PLoS Biology . Specialized cells All of us begin our ...Researchers measure elusive repulsive force from quantum fluctuations
... quantum theory, when the scientists replaced one of the two metallic surfaces immersed in a fluid with one made of silica, the force between them switched from attractive to repulsive. As a result, for the first time, Capasso and his colleagues measured what they have deemed a repulsive Casimir. To ...Miniaturizing memory: Taking data storage to the molecular level
... the inner tube to an electrode, creating the 'zero' or 'one' states required to store information using binary code. When the power source is switched off, van der Waals force which governs attraction between molecules keeps the Inner tube in contact with the electrode. This makes the memory ...Cardiac Science Launches 'Anywhere' Data Management for HIS and EMR Systems
... modality recordings (ECG, stress, and Holter) in one application. Stephen French, program manager-PACS for WellSpan Health of Pennsylvania, switched from GE MUSE to Pyramis. He explained, "We needed a stable system for new and current hardware. Pyramis is better for ECG and stress tests on a ...Agent in red wine found to keep hearts young
... by looking for changes in gene expression in those tissues. As animals age, gene expression in the different tissues of the body changes as genes are switched on and off. In the new study - which compared the genetic crosstalk of animals on a restricted diet with those fed small doses of resveratrol - ...Carbon nanoribbons could make smaller, speedier computer chips
... in and out of the semiconductor. This allows the electric current to either pass through or be blocked, which in turn controls how the devices can be switched on and off, thereby regulating the flow of data. Researchers predict that silicon chips will reach their maximum shrinking point within the next ...Amicus Therapeutics Announces First Quarter 2008 Financial Results
... of Gaucher disease. At the ACMG meeting in March, clinical investigators presented full data from a 4 week Phase 2 study in Gaucher patients who switched from enzyme replacement therapy (ERT) with imiglucerase to the pharmacological chaperone Plicera. Results showed that Plicera was generally safe and ...Ortho Biotech Modifies Prescribing Information for PROCRIT(R) (Epoetin alfa)

CANis previous high-performance resistance-change memory has been licensed to three companies, including Micron Technology and Qimonda, and ...Digital pioneer wins national physics prize
... of the other mirrors. The tilting of the mirrors allows a digital image to be processed from a digital signal because each pixel-like mirror can be switched on and off thousands of times a second to reflect light onto a screen.
