The Effectiveness of Quadratus Lumborum and Fascia Iliaca Blocks on Patient Outcomes in Hip Arthroplasty.

Hip arthroplasty is a common procedure with high costs and difficult rehabilitation. It causes postoperative pain, and this can reduce mobility which extends in-patient time. An optimal analgesia regime is crucial to identify.

Identification of fragments of proximal and distal tubular cells in the urine of patients under cytostatic treatment by immunoelectron microscopy with monoclonal antibodies.

In an attempt to identify the origin of cellular fragments released in the urine of patients treated with potentially nephrotoxic drugs such as cytostatics, two monoclonal antibodies were applied: monoclonal antibody PM II 9 C2, directed against an antigen in distal tubular cells; and monoclonal antibody PM II 39 H11 specific for an antigen in proximal tubular cells. The specificities of both monoclonal antibodies were elaborated in the indirect as well as in the direct immunofluorescence technique. Both antibodies were then used to identify cellular fragments obtained from the urine of patients treated with cytostatic drugs by ultracentrifugation.

Electron microscopic visible ischemic changes of the mitochondrial ATPases in human myocardial cells during extracorporal circulation.

During open heart surgery, needle biopsy material was obtained in four patients, and electron microscopic preparations of the mitochondrial ATPases (coupling factors 1) in human myocardial cells were performed. The pre-ischemic, normal structure of the mitochondrial ATPases and the changes which occur during the ischemic interval were described. An increase in the center-to-center space was shown in the post-ischemic phase.
