Shutting down the HIV assembly line
After infecting a susceptible cell, the human immunodeficiency virus hijacks that cell's normal machinery to produce carbon copies of itself. New HIV particles roll off the cellular assembly lines, burst like bubbles out of the cell, and float off to invade other cellular factories. Vanderbilt University Medical Center investigators have now identified an early step in HIV particle assembly. The...'Shuttling' protein possibly key to resilience of cancer cells
Researchers at Purdue University have discovered a molecular mechanism that may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment and that also may be involved in Alzheimer's and heart disease. The scientists, using an innovative imaging technique invented at Purdue, have learned that a protein previously believed to be confined to the nucleus of health...Microscopic passengers to hitch ride on space shuttle
When space shuttle Atlantis rockets into space later this week, it will take along three kinds of microbes so scientists can study how their genetic responses and their ability to cause disease change. The 'Microbe' experiment, part of the STS-115 space shuttle mission scheduled for launch Aug. 27, will study three common microorganisms -- Salmonella typhimurium, Pseudomonas aeruginosa...Scientists stop autoimmune disease without shutting off immune system
Skin is our first line of defense against infection. But people with a rare, life-threatening autoimmune disease called pemphigus vulgaris lack that protection because their immune system attacks the proteins that hold skin cells together. They develop severe blisters and raw sores as the top layer of their skin falls apart, leaving them extremely vulnerable to infection. The development...Sandia work launched on space shuttle shows live cells influence growth of nanostructures
Albuquerque, N.M. -- Far above the heads of Earthlings, arrays of single-cell creatures are circling Earth in nanostructures. The sample devices are riding on the International Space Station (courtesy of Sandia National Laboratories and the University of New Mexico, NASA and US Air Force) to test whether nanostructures whose formations were directed by yeast and other single cells can cre...DH-2000 with integrated shutter from Ocean Optics
Description:Identical to the DH-2000, but comes with a shutter (controlled via a TTL signal or switch up to 5 Hz) The DH-2000 Deuterium Tungsten Halogen Light Source combines the continuous spectrum of deuterium and tungsten halogen light sources in a single optical path. The combined-spectrum light source produces a powerful, stable output from 215-200 nm. In addition, deep-UV versions of the light...D-2000 with integrated shutter from Ocean Optics
Description:Identical to the D-2000, but comes with a shutter (controlled via a TTL signal or switch) The D-2000 Deuterium Light Source produces a powerful, stable output from 215-400 nm. In addition, deep-UV versions of the light source are available, providing a wavelength range of 190-400 nm. This powerful and stable lamp provides peak-to-peak stability of less than 0.005% and drift of only +/-0....D-2000-DUV with integrated shutter from Ocean Optics
Description:Identical to the D-2000, except that it uses a deep-UV deuterium bulb, which provides a 190-400 nm wavelength range and comes with a shutter (controlled via a TTL signal or switch) The D-2000 Deuterium Light Source produces a powerful, stable output from 215-400 nm. In addition, deep-UV versions of the light source are available, providing a wavelength range of 190-400 nm. This powerful a...DH-2000-DUV with integrated shutter from Ocean Optics
Description:Identical to the DH-2000, except that it uses a deep-UV deuterium bulb, which provides a 190-1700 nm wavelength range and comes with a shutter (controlled via a TTL signal or switch up to 5 Hz) The DH-2000 Deuterium Tungsten Halogen Light Source combines the continuous spectrum of deuterium and tungsten halogen light sources in a single optical path. The combined-spectrum light source pro...DH-2000-DUV with integrated shutter and external TTL control from Ocean Optics
Description:Identical to the DH-2000, except that it uses a deep-UV deuterium bulb, which provides a 190-1700 nm wavelength range and comes with a shutter (controlled via a TTL signal or switch up to 5 Hz) The DH-2000 Deuterium Tungsten Halogen Light Source combines the continuous spectrum of deuterium and tungsten halogen light sources in a single optical path. The combined-spectrum light source pro...Natural-Birth Centers In U.S Pulling Down The Shutters
The closure of a well-known Takoma Park midwifery practice and a Bethesda birth center have sparked an outcry. Those protesting this are some Washington area women who say they are worried by the dwindling number of opportunities to give birth outside a hospital or with a midwife's help. At least seven other birth centers and midwifery practices, many citing rising malpractice insura...SHUTTLE-SL FLEXOR TUOHY-BORST Side-Arm Introducer Sets
Description:Used for the introduction of catheters, balloons and other vascular devices....Shutt® Suction Punch Foreceps/Suction Graspers
Description:Shutt® Suction Punch Forceps provide superior tissue excision with precision-matched, diamond-honed tips. Shutt® Suction Graspers offer an aggressive tooth pattern to capture loose bodies drawn into the jaws. Both feature a unique stress pin buffering system to minimize tip breakage within a joint. In use, the stress pin buffering system applies increasing tension to the instrument handle...
