The molecular processes of particle binding and endocytosis are influenced by the locally changing mobility of the particle nearby the plasma membrane of a living cell. However, it is unclear how the particle's hydrodynamic drag and momentum vary locally and how they are mechanically transferred to the cell. We have measured the thermal fluctuations of a 1(More)
We propose a framework for building electrophysiological predictors of single-trial motor performance variations, exemplified for SVIPT, a sequential isometric force control task suitable for hand motor rehabilitation after stroke. Electroencephalogram (EEG) data of 20 subjects with mean age of 53 years was recorded prior to and during 400 trials of SVIPT.(More)
Phagocytosis, the uptake and ingestion of solid particles into living cells, is a central mechanism of our immune system. Due to the complexity of the uptake mechanism, the different forces involved in this process are only partly understood. Therefore the usage of a giant unilamellar vesicle (GUV) as the simplest biomimetic model for a cell allows one to(More)

Regarding experimental data on the multi-factorial reduction of the thermostability of collagen, the following sequence of the mechanism of Dupuytren's contracture is discussed: 1. Hereditary or acquired weakness of fibres of the palmar fascia 2. Further disturbance of the physical property of collagen by the cumulative effects of mechanical, i.e.(More)

Structure and dynamics of skin-anchoring fibers in the palmo-digital zone of the normal and diseased hand are demonstrated. The palmar fibromatosis causes fixation of these fibers in flexion. The disease must not be considered to be a finger contraction, but as inability to extend the fingers. In this concept the so-called myofibroblasts are regarded not as(More)

Areas of disordered fibrillar structure similar to kinking deformities have been observed in specimens from ruptured tendons. It seems possible to compare this phenomenon with experimentally produced deformations. The significance for the pathomechanics of tendon rupture is discussed. In Exzisaten aus dem Rupturbereich von Sehnen wurden fibrilläre(More)

The first part of the film demonstrates by means of graphic representation the various clinical manifestations of primary hyperparathyroidism. The second part deals with diagnostic measures, such as biochemical serum analyses, X-ray studies, bone biopsy and renal tubular function tests, e.g. phosphate clearance and reabsorption and cAMP excretion in the(More)

Typical localization and growth behavior of esophageal cancer is described graphically. The technique of total gastric transposition for esophageal replacement (Kirschner procedure) is outlined schematically and by two clinical examples. In graphischer Schematisierung werden bevorzugte Lokalisation und Wachstumsverhalten des Oesophaguscarcinoms(More)
