The male copulatory system of the European pinnotherid species Pinnotheres pisum, Pinnotheres pectunculi, and Nepinnotheres pinnotheres was investigated by gross morphology, scanning electron microscopy, histological methods, and confocal laser scanning microscopy. The brachyuran copulatory system is consistently formed by paired penes and two pairs of(More)
Reliability of two different spiroergometric systems was investigated by comparing gas exchange measurements from two consecutive identical bicycle ergometer ramp exercise tests which were conducted after an initial habituation trial. Twenty-three healthy subjects (age: 25+/-5 years; weight: 71+/-10 kg; peak oxygen uptake: 55+/-9 ml x min(-1) x kg(-1)) took(More)
Internal fixation of unstable intertrochanteric fractures of osteoporotic femurs often leads to complications, which are primarily caused by the mechanically weak bone. The aim of this study was to test whether a new glass-ionomeric cement could reinforce the weak trabecular bone of the femoral head and thus improve the preliminary stability of dynamic hip(More)
