Postural sway during upright stance was analyzed in 12 patients with phobic postural vertigo (PPV) and in 12 age-matched healthy volunteers. Recordings were made under different conditions (with the eyes open or closed): when standing on a foam rubber pad with the head upright, turned 30 degrees to the right or left, or during 1 Hz horizontal head(More)
Fast alle Patienten mit amyotropher Lateralsklerose (ALS) leiden im Verlauf der Erkrankung an Symptomen der chronischen Hypoventilation. Diese Symptome können Jahre vor dem Tod auftreten und die Lebensqualität erheblich beeinträchtigen. Eine Möglichkeit zur Linderung dieser Beschwerden stellt die nichtinvasive, intermittierende Selbstbeatmung über Maske(More)
Dopamine transporter imaging was performed in 18 patients with sporadic amyotrophic lateral sclerosis (ALS) and 11 age matched controls with [I-123] IPT (N-(3-iodopropen-2-yl)-2beta-carbomethoxy-3beta(4-chlorophen yl)-tropane), a new cocaine analogue that selectively binds to the dopamine transporter located on dopaminergic nerve terminals. Image analysis(More)
Almost all patients with amyotrophic lateral sclerosis (ALS) experience symptoms of nocturnal hypoventilation during the course of the illness. These symptoms can develop years before death and may severely affect quality of life. Non-invasive intermittent home mechanical ventilation (HMV) via mask is a possible palliative measure for these symptoms, which(More)

devices. In addition to applications as efficient colour converters, nanocrystals have been considered promising building blocks for colour-selectable optical-gain media in lasing applications. One complication associated with lasing applications of nanocrystals is the requirement for extremely fast pumping that competes with non-radiative Auger(More)
