Patients who had received livers from hepatitis B virus core antibody (HBcAb) positive (indicates prior exposure to hepatitis B) and/or hepatitis C virus (HCV) positive donors had similar graft and patient survival compared to patients who received HBcAb negative or HCV negative livers, according to a study by the University of Pittsburgh’s Thomas E. Starzl Transplantation Institute. The results of their findings are being presented today at sixth annual American Transplant Congress, the joint scientific meeting of the American Society of Transplant Surgeons and the American Society of Transplantation at the Washington State Convention & Trade Center in Seattle.
To help alleviate the shortage of organs, there has been an increase in the transplantation of livers obtained from extended criteria donors, such as organs from HBcAb positive and HCV positive donors. In the Pitt study, the researchers conducted a seven-year review of liver transplant recipients who received HBV positive and HCV positive organs between 1997 and 2004. The patients were divided into three groups. Group one consisted of 28 patients that received both HBcAb positive and HCV positive livers; the second group consisted of 58 patients that received HBcAb positive livers; and the third group consisted of 34 patients that received HCV positive livers. Patient and graft survival and recurrence of the HBV and HCV infections were compared between the various groups of patients.
Treatment to prevent recurrent HBV infection consisted of hepatitis B immune globulin and/or lamivudine for groups one and two. The mean follow up for all patients was two years and there were no significant differences between recipients of all groups with respect to age, sex and MELD scores – a liver transplant scoring system which estimates a patient’s risk of dying while waiting for the transplant.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
