BACKGROUND The present study aimed at investigating the expression of the Na(+)-Ca2+ exchanger and its functional role in human failing myocardium. METHODS AND RESULTS Na(+)-Ca2+ exchanger mRNA and protein levels were examined in nonfailing (NF, n = 8) and failing human myocardium (New York Heart Association functional class IV) with idiopathic dilated(More)
72 consecutive patients with suspected parkinsonian syndromes (PS) were studied by dopamine transporter (DAT) and D2 receptor SPECT in order to evaluate the accuracy of combined SPECT imaging. In the follow-up, the patients were diagnosed as having Parkinson’s disease (PD, n = 25), dementia with Lewy bodies (DLB, n = 6), multiple system atrophy (MSA, n =(More)
In the human, visually evoked potentials (VEP) and cerebral oxygenation changes, as measured by near-infrared spectroscopy (NIRS), are assessed to elucidate the relation between electrophysiological and vascular responses to a checkerboard stimulus reversing at 3 Hz. Habituation of either response is analysed on two time scales. Within the 1-min stimulation(More)
Neuropeptide release and the expression of c-fos like immunoreactivity (c-fos LI) within trigeminal nucleus caudalis neurons (TNC) are activation markers of the trigeminal nerve system. Glyceryltrinitrate (GTN) is believed to stimulate the trigeminal nerve system, thereby causing headache. We examined the effects of a 30 min NO-donor infusion on CGRP(More)
We used a computational analysis of open loop handwriting movements and a clinical rating scale for monitoring the effect of apomorphine in 16 patients with early untreated parkinsonism [subsequently L-DOPA responsive, probable Parkinson's disease (PD)], six patients with long-standing PD with L-DOPA associated motor fluctuations, and seven patients with(More)
The authors compared the efficacy of three different doses (18.75, 37.5, and 75 MU per parotid gland) of botulinum toxin A (BTX-A; Dysport, Ipsen Pharma, Germany) injections vs vehicle in patients with sialorrhea (n = 32) using a single-center, prospective, double-blind, placebo-controlled dose-finding study. The primary endpoint was achieved with 75 MU(More)
Single photon emission computed tomography (SPECT) with 123I-iodobenzamide (123I-IBZM) was used in a prospective study to investigate 83 patients with parkinsonism (Hoehn and Yahr stages I to III) who had not been previously treated with dopamimetic drugs. All patients had clinical signs that were compatible with Parkinson's disease. An additional 13(More)
The aim of this study was to investigate the efficacy of riboflavin for the prevention of migraine. An open label study was performed in a specialized outpatient clinic. Patients received 400 mg riboflavin capsules per day. Headache frequency, duration, intensity and the use of abortive drugs were recorded at baseline and 3 and 6 months after treatment.(More)
BACKGROUND Water drinking elicits a sympathetically mediated pressor response in multiple-system atrophy patients through an unknown mechanism. We reasoned that gastrointestinal distention, hyposomotic stimulation, or both contribute to the water-induced pressor response. METHODS We compared the response to normal saline and water on blood pressure in 10(More)
We investigated the cases of 55 patients with parkinsonism and prior dopaminomimetic therapy in whom the response to this treatment was questionable or reported to be negative. None of these patients had shown motor fluctuations prior to this study. We compared the results of imaging of dopamine-D2 receptors by using(More)
