BACKGROUND The present study was designed to define the prevalence and characteristics of skeletal muscle alterations in patients with chronic heart failure (CHF) and their relation to exercise capacity. METHODS AND RESULTS The ultrastructure of skeletal muscle was analyzed by ultrastructural morphometry in 57 patients with CHF and 18 healthy controls.(More)
Epithelial cell adhesion molecule (Ep-CAM; CD326) is used as a target by many immunotherapeutic approaches, but little data are available about Ep-CAM expression in major human malignancies with respect to level, frequency, tumour stage, grade, histologic tumour type and impact on survival. We analysed by immunohistochemical staining tissue microarrays with(More)
Hypoplastic coronary artery disease is a rare condition that may lead to myocardial infarction and sudden death. Here we describe for the first time an isolated hypoplasia of the left circumflex artery (LCX). An otherwise healthy and athletically active 16-year-old boy was admitted to the intensive care unit (ICU) after out-of-hospital cardiac arrest. He(More)
The recommended treatment method for chondropathy from Morscher 1978 using a sagittal patellaosteotomy was tested experimentally with contact area measurements with the erasing method on 11 corpse knees of the types II, II/III and III. Measurements were made in the bending region up to 90 degrees, and in isolated positions up to 140 degrees. The(More)
The influence of two fixation buffers on the quantitative cytoarchitecture of the cochlear spiral ganglion in guinea pigs was evaluated morphometrically. After fixation with phosphate buffered 1.3% OsO4 granular spiral ganglion cells lost 45% of their average individual volume as compared to the volume after fixation with s-collidine buffered 1.3% OsO4.(More)
This is the first morphometric analysis of the cochlear spiral ganglion. Therefore the ganglion was subdivided in precisely defined compartments. We found that the normal, untreated spiral ganglion in guinea pigs contains 58% ganglion cells of the granular type, 26% satellite cells and Schwann cells, 8.6% extracellular space, 6.4% myelinated nerve fibers(More)
The comparison of ultrastructural and ultrastructural-morphometric findings in spiral ganglion cells subsequent to broad noise with 105 dB SPL over a period of 40 min demonstrates that there are morphometric changes of the cytoarchitecture of granular ganglion cells even without evident ultrastructural changes. Morphometric analyses shows a significant(More)
The cochlear spiral ganglion of rats consists of 61.8% granular ganglion cells, 22.4% satellite cells and Schwann cells, 9.3% extracellular space, 4.8% myelinated nerve fibers and 1.4% filamentous ganglion cells. The granular ganglion cells consist of 76% cytoplasmic components and 24% nuclei. Their cytoplasm contains 66.3% hyaloplasm, 11.4% mitochondria,(More)
