• UF-led effort creates virus reference standard that can improve patient safety in clinical trials

  The use of viruses as vehicles for delivering genes to replace malfunctioning or missing ones holds promise for treating many disorders. Adeno-associated viruses are one type of vector being used increasingly in human gene therapy clinical trials and laboratory studies leading up to those trials. Bu more

• 2 lines account for most human embryonic stem cell research, Stanford scholar finds

  For the past eight years, scientists who wanted to use federal funds for research on human embryonic stem cells had to restrict their studies to 21 cell lines approved by the National Institutes of Health. But an analysis by a researcher at the Stanford University School of Medicine suggests that on more

• CellGenix Technologie Transfer GmbH: 15 Years of Innovation and Leadership

  2009 is a special year for CellGenix, according to the company. Cellgenix is celebrating its 15th anniversary. CellGenix was founded in May 1994 as a Spin-off from the University Medical Center Freiburg and has developed continuously ever since. 1997 the company launched the first GMP quality serum- more

• Microsatellite Analysis of Grapevine Varieties by High-Resolution Amplicon Melting Analysis
  

  Certification of grapevine scion and rootstock varieties is becoming an increasingly important issue in viticulture. Many rootstocks are derived from the same parentage - for example 5C, SO4, 5BB, 125AA, and 420A Mgt are all used in New Zealand and are all derived from crosses between Vitis berlandieri and Vitis riparia. This use of limited genetic stock is not uncommon when compared with other countries and means that cultivar determination based on ampelography (visual characteristics of grapevines) can be difficult at times due to the high similarities. more

• The Determination of Hazardous Substances According to RoHS and WEEE Directives
  

  1st July 2006 is an important deadline for the electro- and electronics industries. This date bans hazardous substances like lead, cadmium, mercury, hexavalent chromium and polybrominated biphenyls and diphenyl ethers from electro- and electronic equipment. This restriction, even though in discussion since 1991, has become more and more important from year to year because of tons of electronic waste releasing toxic substances which are accumulated in the environment, the food chain and all human beings. In order to enforce the substances ban and the limitation or substitution of hazardous components, elemental analysis is obviously the most important control measure for monitoring limiting values. This requires precise analytical systems such as X-ray fluorescence, ICP- and atomic absorption spectrometers. These instruments are able to detect trace concentrations of hazardous compounds - for example cadmium, using an atomic absorption spectrometer in the flame atomization mode up to 0.1 mg/L, or using the di more

• Comparative Performance of Thin Layer Agar and Löwenstein‐Jensen Culture for Diagnosis of Tuberculosis

  Abstract Sputum smear microscopy for the diagnosis of tuberculosis (TB) is cheap and simple but its sensitivity is low. Culture on Löwenstein‐Jensen (LJ) is more sensitive but it takes a long time to yield results. Thin‐Layer Agar (TLA) culture was suggested as an equally sensitive and faster al more

• Preparation of deuterium‐labeled biotransformation products of 2,4,6‐trinitrotoluene

  Methods for the preparation of deuterium‐labeled analogs to six prominent biotransformation products of the explosive 2,4,6‐trinitrotoluene were developed. These are useful as reference standards for stable isotope dilution techniques and for solid state 2H NMR spectroscopic studies. Although synt more
