The present study evaluated the effects of once-daily memantine (20 mg) treatment on cognition and communication in patients with moderate to severe Alzheimer's disease (AD). In a multicenter, single-arm open-label study, outpatients diagnosed with AD (MMSE < 20; n = 97) were titrated from 5 mg to 20 mg once-daily memantine over 4 weeks. Once-daily(More)
Molten carbonate fuel cells provide a promising technology for the operation of future stationary power plants. In order to enhance service life, a detailed understanding of the dynamical behavior of such fuel cell systems is necessary. In particular, fast load changes shall be simulated, respectively optimized without risking material stress due to the(More)
INTRODUCTION The Relevant Outcome Scale for Alzheimer's Disease (ROSA) is a new observer rating instrument recently developed for routine medical practice. The validity and reliability of ROSA as well as sensitivity to changes due to intervention were examined in an open-label, single-arm, multicenter clinical study in patients with Alzheimer's disease(More)
Numerical results for the optimal control of load changes of a molten carbonate fuel cell system are presented. The extensive numerical computations are based on a detailed validated mathematical model. This model describes the dynamics of the gas flow, the electro-chemical reactions, the cell temperature, and the electrical potential fields. The(More)
OBJECTIVE The Relevant Outcome Scale for Alzheimer's disease (ROSA) is a novel, valid, and reliable instrument for multidimensional assessment of Alzheimer's disease (AD) symptoms across all severity stages. The ROSA and four standard instruments -- the Alzheimer's disease Assessment Scale-cognitive (ADAS-cog), Severe Impairment Battery (SIB), Disability(More)
The purpose of the study was to evaluate the feasibility of anastomotic stent application in a porcine aortoiliac graft model. In a total of 10 pigs, a polytetrafluoroethylene aortobi-iliac graft was implanted through a midline abdominal incision. The lower edge of the iliac vessel was graft-inverted about 1 mm to produce irregularities at the downstream(More)
