Nickel and aluminum powders were mechanically alloyed with 10 or 30 vol.% refractory metal powders (molybdenum or tungsten) for times up to 50 h. Intermetallic synthesis takes place after lo-20 h alloying, with concomitant dispersion of the inert refractory metal phase, resulting in an NiAl matrix containing fine refractory dispersoids. The reactive synthesis step is direct, without intermediat...

Thrombotic thrombocytopenic purpura (TTP) is a life threatening condition associated with formation of platelet thrombi. Deficiency of ADAM TS 13 with presence of inhibitory anti-ADAM TS 13 Immunoglobulin G antibody is seen in patients with acquired TTP. TTP in patients on interferon therapy for chronic hepatitis C has rarely been reported. Furthermore, successful treatment of an initial episod...

The aim of this study was to test the reliability of the commonly used blocking technique for measuring the conduction velocity spectrum of the peripheral motor nerve in man, as first described by Hopf in 1962. Electromyographic recordings were carried out with a selectivity permitting identification of single motor unit potentials. The conduction velocity of the single alpha motor axon was det...

Approximately 30% of epileptic patients remain untreated, in spite of trials with maximum tolerable doses of more than one drug. The RalA binding protein 1 (RALBP1/RLIP76), a multifunctional, anti-apoptot-ic, multidrug transporter protein, has been proposed as being responsible for the drug resistance mechanism in epilepsy. We have investigated polymorphic differences in the coding regions and ...

Abstract Refractory ‘stuffed’ pyrochlores such as Gd 2 TiO 5 are of interest for nuclear applications, including matrices actinide disposition and neutron absorbers in control rods. Here, we report the results a preliminary comparative investigation synthesis by molten salt conventional solid-state synthesis. We show that proceeds from pyrochlore phase Ti O 7 which is first formed kinetic produ...
