We have analysed 3380 chromosomes (1690 unrelated individuals) from twenty-four populations for the presence of factor V Leiden, an important risk factor in venous thromboembolism. The allele frequency in 618 Europeans was 4.4%, with the highest prevalence among Greeks (7%). It was 0.6% in Asia Minor. Factor V Leiden was not found in any of 1600 chromosomes(More)
Current concepts of transcranial magnetic stimulation (TMS) over the primary motor cortex are still under debate as to whether inhibitory motor effects are exclusively of cortical origin. To further elucidate a potential subcortical influence on motor effects, we combined TMS and unilateral subcortical electrical stimulation (SES) of the corticospinal(More)
Any attempt to restore visual functions in blind subjects with pregeniculate lesions provokes the question of the extent to which deafferented visual cortex is still able to generate conscious visual experience. As a simple approach to assessing activation of the visual cortex, subjects can be asked to report conscious subjective light sensations(More)
Here, we report a mutation screening by single-stranded conformational analysis of the astroglial human brain glutamate transporter (HBGT) II complementary DNA in patients with amyotrophic lateral sclerosis. The conformational analysis data indicate a lack of sequence variations in the HBGT II coding region in 6 patients with amyotrophic lateral sclerosis(More)
PURPOSE Carisbamate, a novel neuromodulatory agent with antiepileptic properties, was evaluated in patients with photoparoxysmal responses to intermittent photic stimulation (IPS) in this multicenter, non-randomized, single-blind, placebo-controlled, proof-of-concept study. METHODS Eighteen Caucasian patients (14 females, 4 males) with a mean age of 30(More)
Oxidative stress in acute respiratory distress syndrome (ARDS) is considered as an important pathophysiological mechanism in acute impairment of lung function. The present study investigated whether a pulmonary oxidant-antioxidant imbalance is indicated by substantial oxidative modification of proteins in bronchoalveolar lavage (BAL) fluid. Oxidatively(More)
Spatial changes of the motor cortical representation of the biceps brachii muscle (stump muscle) were studied in ten patients with long-standing amputations at the level of the forearm. Motor output maps were established by focal transcranial magnetic stimulation on a skull surface grid overlying the motor cortex. Characteristics of the motor output map(More)
Fast ballistic flexion movements of the wrist are produced by a triphasic pattern of electromyographic (EMG) activity in flexor and extensor muscle. Whereas it is generally accepted that the primary motor cortex generates the first agonist burst (AG1), its contribution to the following antagonist burst (ANT) and second agonist burst (AG2) is unresolved. We(More)
In a prospective randomised trial, 249 patients who had aortocoronary vein bypass surgery were assigned either to a platelet inhibitory drug regimen or to standard anticoagulant therapy. Treatment was replaced by placebo in half of the patients in each group after 3 months. The platelet inhibitory drug regimen--very low-dose aspirin combined with(More)
