The quality of the sublethal damage (SLD) after irradiation with high-linear energy transfer (LET) ion beams was investigated with low-LET photons. Chinese hamster V79 cells and human squamous carcinoma SAS cells were first exposed to a priming dose of different ion beams at different LETs at the Heavy Ion Medical Accelerator in the Chiba facility. The cells were kept at room temperature and th...

Given recent profound improvements in the effectiveness of antiviral treatment for chronic Hepatitis C virus (HCV) infection, we aimed to describe the characteristics of patients referred to hepatology expert centres in France from 2000 to 2007 and from 2010 to 2014, and to identify factors associated with severe liver disease at their first visit for evaluation. We analysed data from two sourc...

Introduction. Second-line antituberculosis drugs (SLDs) are used for treating multidrug-resistant tuberculosis (MDR-TB). Prolonged delays before confirming MDR-TB with drug susceptibility testing (DST) could result in transmission of drug-resistant strains and inappropriate use of SLDs, thereby increasing the risk of resistance to SLDs. This study investigated the diagnostic delay in DST and pr...

The median preoptic nucleus (MnPN) and the ventrolateral preoptic area (vlPOA) contain putative sleep-regulatory neurons that exhibit elevated discharge rates during sleep compared with waking. Expression of c-Fos protein immunoreactivity (IR) in GABAergic neurons in the MnPN and the vlPOA is high in spontaneously sleeping rats and in rats undergoing recovery sleep after sleep deprivation. Howe...

We prove that the universal lattices – the groups G = SLd(R) where R = Z[x1, . . . , xk], have property τ for d ≥ 3. This provides the first example of linear groups with τ which do not come from arithmetic groups. We also give a lower bound for the τ -constant with respect to the natural generating set of G. Our methods are based on bounded elementary generation of the finite congruence images...

This report covers preliminary measurements from SLD on heavy quark production at the Zu, using 150.000 hadronic Zu decays accumulated during the 1993-1995 runs. A measurement of Rt, with a lifetime double tag is presented. The high electron beam polarization of the SLC is employed in the direct measurement of the parity-violating parameters At, and Ac by use of the left-right forward-backward ...

We report a new measurement ofRb = ΓZo→bb/ΓZ0→hadrons using a double tag technique where the b selection is based on topological reconstruction of the mass of the B-decay vertex. The measurement was performed using a sample of 150k hadronic Z events collected with the SLD at the SLAC Linear Collider during the years 1993-1995. The method utilizes the 3-D vertexing abilities of the SLD CCD pixel...
