The purpose of this study was to investigate the biomechanics of cross-country sit-skiing in simulated and natural skiing. Thirteen international level athletes participated in a ski ergometer test (simulated conditions) and a test on snow in a ski-tunnel (natural conditions) using their personal sit-ski. Tests in both conditions were performed at(More)
Five different glomerular immunohistochemistry markers were evaluated and compared in four different acute and chronic rat kidney disease models. Progression of glomerular or podocyte damage was shown in the puromycin aminonucleoside nephrosis (PAN) and Zucker fatty/spontaneously hypertensive heart failure F1 hybrid (ZSF1) rat model. Progression and(More)
BACKGROUND Retraining walking in patients after hip or knee arthroplasty is an important component of rehabilitation especially in older persons whose social interactions are influenced by their level of mobility. The objective of this study was to test the effect of an intensive inpatient rehabilitation program on walking speed and gait symmetry in(More)
The purpose of this study was to investigate whether the stretch-shortening cycle (SSC) contraction is integrated in neuromuscular activation in upper body muscles during double poling in cross-country skiing. Thirteen elite skiers performed double poling roller-skiing at increasing treadmill velocities of 9, 15, 21, 27 km h(-1) and their individual maximal(More)
INTRODUCTION Leg length inequalities (LLI) are a common finding. Rasterstereography offers a non-invasive, contact-free and reliable method to detect the effects of LLIs on spinal posture and pelvic position. MATERIALS AND METHODS A total of 115 subjects were rasterstereographically examined during different artificially created leg length inequalities(More)
PURPOSE The purpose of this study was to investigate age differences in the response of the spine and pelvis to simulated leg length inequalities (LLIs). METHODS A total of 107 subjects, separated into three age groups (group 1: 20-39 years, group 2: 40-59 years, group 3: >60 years), were used to evaluate for any age effects in the response to LLIs. LLIs(More)
Immunochemical homogeneous human pepsinogen I-group (PgI) was purified by solid immunoadsorbent and by DEAE-chromatography from gastric mucosa. PgI contained five electrophoretic distinct bands at pH 8.2 but only four bands at pH 5.6. After acid activation human pepsin (PI) was separated from the inhibitory peptide by affinity chromatography using(More)
Human pepsinogen II (PgII) was purified from human gastric mucosa by immunoadsorbents using anti-PgII antiserum. Contaminating pepsinogen I (PgI) was adsorbed by a subsequent anti-PgI immunoadsorbent. PgII was further purified on DEAE-Sphadex A50. By agar gel enzyme electrophoresis (AEE) at pH 8.2 PgII was separated into five proteolytic bands, demonstrated(More)
Purpose of this study was to evaluate the reliability and validity of 4D rasterstereography under dynamic conditions. Therefore simulated anatomical fixed points on a wooden plate were measured during different movements. Seven different motion patterns in all three angles of space were evaluated. The simulated parameter trunk length was measured with an(More)
