Stellar radii of M giants
Abstract We determine the stellar radii of the M giant stars in the Hipparcos catalogue3 that have a parallax measured to better than 20% accuracy. This is done with the help of a relation between a… Expand
Wind clumping and the wind-wind collision zone in the Wolf-Rayet binary gamma ² Velorum observations at high and low state. XMM-Newton observations at high and low state
We present XMM-Newton observations of γ 2 Velorum (WR 11, WC8+O7.5III, P = 78.53 d), a nearby Wolf-Rayet binary system, at its X-ray high and low states. At high state, emission from a hot… Expand
Proton magnetic resonance spectroscopy of the motor cortex in 70 patients with amyotrophic lateral sclerosis.
OBJECTIVE To evaluate proton magnetic resonance spectroscopy for detection and monitoring of upper motoneuron degeneration in patients with amyotrophic lateral sclerosis. METHODS Seventy patients… Expand
Hepatocellular carcinoma: detection with gadolinium- and ferumoxides-enhanced MR imaging of the liver.
PURPOSE To test the hypothesis that the accuracy of gadolinium- and ferumoxides-enhanced magnetic resonance (MR) imaging is different in small (< or =1.5-cm) and large (>1.5-cm) hepatocellular… Expand
Physical conditions and elemental abundances in the symbiotic novae V1016 Cyg, HM Sge and HBV 475
Les observations spectroscopiques UV, optiques et IR-proche de 3 novae symbiotiques, V1016 Cyg, HM Sge et HBV 475, sont presentees. Les spectres sont analyses. Les abondances en H, He, C, N, O et Ne… Expand

- 9 February 1996
Lateral and anteroposterior radiographs of the ankles of 800 Central Europeans aged 20 to 79 were analyzed with regard to sexual dimorphism. All the distances, but not the angles, of the calcaneus… Expand
A spectroscopic search for the non-nuclear Wolf-Rayet population of the metal-rich spiral galaxy M 83
We present a catalogue of non-nuclear regions containing Wolf-Rayet stars in the metal-rich spiral galaxy M 83 (NGC 5236). From a total of 283 candidate regions identified using He ii λ 4686 imaging… Expand
Occlusion of the pig superior sagittal sinus, bridging and cortical veins: multistep evolution of sinus-vein thrombosis.
Cerebral sinus-vein thrombosis may lead to severe hemodynamic changes, elevated intracranial pressure (ICP), and brain edema. It is supposed that progression of the thrombus from the sinus into… Expand
MR imaging and cardiac pacemakers: in-vitro evaluation and in-vivo studies in 51 patients at 0.5 T.
PURPOSE To evaluate the safety and feasibility of magnetic resonance (MR) imaging at 0.5 T in patients with implanted cardiac pacemakers. MATERIALS AND METHODS Twenty-one models of pacemakers and… Expand
Increased Expression of Matrix Metalloproteinases in Mononuclear Blood Cells of Normal-Tension Glaucoma Patients
PurposeGlaucomatous optic neuropathy involves tissue remodeling by matrix metalloproteinases (MMPs). In this study we investigated MMP gene expression in circulating leukocytes isolated from normal… Expand
