While the nations blood supply is safe overall and there is a relatively small likelihood that transfusion recipients will acquire a transmitted disease, there are still risks involved when transferring one persons blood into another. The advent of new diseases, such as West Nile Virus (WNV), increases the need for further clinical vigilance and improved screening methods.
The blood supply is currently inspected in minipools with nucleic acid testing for HIV, hepatitis C virus (HCV) and WNV, but there is now a movement toward screening individual blood donations with such examinations. Additionally, researchers are learning more about reducing the risk of transferring specific diseases that may not affect healthy individuals but may seriously hurt immunocompromised patients, who often receive donated blood. Several studies of this nature are being presented during the 45th Annual Meeting of the American Society of Hematology.
"Modern medicine has contributed exponentially to the quality of medical care and has provided us with the opportunity to conduct successful blood transmissions to save millions of lives every year," said Stanley Schrier, M.D., President-Elect of the American Society of Hematology and Active Emeritus Professor of Medicine in the Division of Hematology at Stanford University School of Medicine. "However, it remains duly important that we not compromise our patients overall well-being while trying to improve their situation."

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
