BACKGROUND Acute unilateral vestibular loss is a balance disorder that is accompanied by vertigo symptoms and concomitant vegetative symptoms, including nausea and vomiting. Patients are frequently confined to bed rest but may continue to experience vertigo symptoms. A well-established antivertiginous therapy consisting of cinnarizine and dimenhydrinate at(More)
BACKGROUND Vestibular neuritis (VN) is a strongly disabling disease of the peripheral vestibular system. Rapid and effective relief of symptoms is important to allow patients to promptly return to normal physical activity. OBJECTIVE The aim of this prospective, randomized, double-blind study was to evaluate the efficacy of a fixed low-dose combination of(More)
INTRODUCTION Peripheral vestibular disorders frequently lead to the manifestation of symptoms of vertigo. The objective of this study was to compare the efficacy and tolerability of a fixed combination of cinnarizine 20mg and dimenhydrinate 40mg per tablet with betahistine (betahistine dimesylate) 12mg per tablet in the treatment of patients with otogenic(More)
BACKGROUND AND OBJECTIVE Vestibular dysfunction commonly leads to - often severe - vertigo symptoms. The objective of this study was to compare the antivertiginous efficacy and tolerability of a fixed combination of cinnarizine/dimenhydrinate with those of betahistine in patients with acute vertigo due to vestibular disorders. METHODS Sixty-six patients(More)
Thirty-seven patients suffering from vertigo associated with vertebrobasilar insufficiency participated in our prospective, single-center, double-blind, comparative study. Patients were randomly allocated to treatment with placebo; betahistine (12 mg betahistine dimesylate, one tablet three times daily); or the fixed combination of 20 mg cinnarizine and 40(More)
Peptide substrates of the general structure Ac-Tyr-Ly1-Ly2-..-Lym-NH2 and Ac-Phe-Ly1-NH2 have been synthesized and subjected to alpha-chymotrypsin-catalyzed hydrolysis to collect information on the interactions between the enzyme active site and the amino-acid residues Ly1, Ly2, etc., C-terminal to the susceptible bond of the peptide. For this purpose(More)
Molecularly well-defined iron pincer complexes promote the aqueous-phase reforming of methanol to carbon dioxide and hydrogen, which is of interest in the context of a methanol and hydrogen economy. For the first time, the use of earth-abundant iron complexes under mild conditions for efficient hydrogen generation from alcohols is demonstrated.
Hydrogen produced from renewable resources is a promising potential source of clean energy. With the help of low-temperature proton-exchange membrane fuel cells, molecular hydrogen can be converted efficiently to produce electricity. The implementation of sustainable hydrogen production and subsequent hydrogen conversion to energy is called "hydrogen(More)
BACKGROUND AND OBJECTIVE Vertigo may arise from dysfunction in the peripheral and/or the central vestibular system. Simultaneous activity of a medication at both sites will serve to improve the efficacy of antivertigo treatment. The aim of this study was to compare the efficacy and tolerability of a fixed combination of the peripherally acting cinnarizine(More)
