[Carpal lesions associated with dislocated fractures of the distal radius. A systematic screening of 104 fractures using preoperative CT and MRI].

Background: The functional outcome of surgically treated dislocated fractures of the distal radius is limited and does not correlate with radiographic results. Additional carpal lesions are assumed to be the cause. This study has evaluated which carpal lesions are associated with dislocated fractures of the distal radius.

Effects on the ubiquitin proteasome system after closed soft-tissue trauma in rat skeletal muscle.

Previous studies have suggested that an increased catabolic stage of skeletal muscle in pathological situations is mainly a reflection of ubiquitin-proteasome system-controlled proteolysis. The proteolytic mechanisms that occur after local muscle trauma are poorly defined. We investigated the effects of closed soft-tissue trauma on ubiquitin-proteasome dependent protein breakdown in rats (n = 25).

Evaluation of dehiscences using cone beam computed tomography.

Objective: To validate the use of three-dimensional (3-D) surface rendering (SR) images to quantify the height of alveolar dehiscences.

Materials And Methods: Twenty-four dehiscences were created on 9 incisors, 9 canines, and 6 premolars on 4 cadaver skulls. i-CAT cone beam computed tomography scans (CBCTs) were taken of each skull at .

Regulation of the ubiquitin proteasome system in mechanically injured human skeletal muscle.

Metabolic consequences of direct muscle trauma are insufficiently defined. Their effects on the ubiquitin-proteasome pathway (UPP) of protein degradation in human skeletal muscles are as yet unknown. Thus, we investigated whether the UPP is involved in the metabolic response evoked in directly traumatized human skeletal muscles.
