Publikováno v: European Journal of Neurology. 7:183-190

The aim of our study was to establish colour Doppler-assisted duplex imaging (CDDI)-criteria to predict an angiographic internal carotid artery (ICA) stenosis of at least 70%, according to the North American Symptomatic Carotid Endarterectomy Trial (

Efficient Portfolios in the Asset Liability Context

Autor: Alex Keel, Heinz Müller

Publikováno v: ASTIN Bulletin. 25:33-48

The set of efficient portfolios in an asset liability model is discussed in detail. The occurence of liabilities leads to a parallel shift of the efficient set. Under an appropriate assumption, the shift vector can be decomposed in different componen

A double-blind, placebo controlled comparison of the morphine sparing effect of oral rofecoxib and diclofenac for acute renal colic

Autor: Hans-Peter Schmid, Daniel S. Engeler, Daniel Ackermann, Joseph Osterwalder, Alex Keel

Publikováno v: The Journal of urology. 174(3)

We compared the morphine sparing effect of a single dose of 50 mg oral rofecoxib, 3, 8-hourly doses of 50 mg diclofenac and placebo for acute renal colic.Patients who were 18 to 69 years old with clinically diagnosed acute renal colic and a visual an

Impaired somatosensory discrimination of shape in Parkinson's disease: association with caudate nucleus dopaminergic function

Autor: M. Nienhusmeier, Bruno Weder, Peter Vontobel, Thomas Vonesch, Wolfgang Zaunbauer, K. L. Leenders, Alex Keel, H.P. Ludin

Publikováno v: Hum Brain Mapp

Tactile discrimination of macrogeometric objects in a two‐alternative forced‐choice procedure represents a demanding task involving somatosensory pathways and higher cognitive processing. The objects for somatosensory discrimination, i.e., rectan

Somatosensory discrimination of shape: prediction of success in normal volunteers and Parkinsonian patients

Autor: M. Nienhusmeier, Alex Keel, Bruno Weder, H.P. Ludin, K. L. Leenders

Publikováno v: Experimental Brain Research, 120(1), 104-108. SPRINGER

Tactile discrimination of macrogeometric objects in a two-alternative forced-choice procedure represents a complex task including somatosensory and higher-order cognitive processing. The objects for somatosensory discrimination were rectangular paral
