[Interventional endovascular therapy of infrarenal abdominal aortic aneurysm].

The catheter-based interventional therapy (endovascular aortic repair EVAR) of abdominal aortic aneurysms (AAA) has gained an established place in the spectrum of therapeutic options. The procedure is characterized by low peri-interventional morbidity and mortality. Multislice computed tomography (CT) has a dominant role in defining the correct indications and in selecting an appropriate stent graft prior to the intervention.

[CT-guided cutting needle biopsies of thoracic lesions in patients with negative bronchoscopic findings].

Purpose: The usefulness and the complication rate of CT-guided core biopsies for obtaining specimens for histopathological examinations in patients with uncertain thoracic lesions were evaluated.

Materials And Methods: Under local anesthesia CT-guided core biopsies were performed in 121 patients using tru-cut systems (14-18 gauge). Prior to CT all patients underwent bronchoscopy without obtaining sufficient material for a definite histopathological diagnosis.

[Thrombosis of developmental venous anomaly and consecutive venous infarction].

Developmental venous anomalies (DVA) are congenital aberrations in the cerebral venous system reflecting failure of normal embryogenesis. They are considered the most common intracranial vascular malformation. Although they are generally regarded as benign entities, their clinical significance remains controversial--case reports do exist considering DVA to be the origin of thrombosis, cerebral ischemia, and hemorrhage.

[PACS: from project to reality. Report of experiences on full digitalisation of the radiology department of a major hospital].

Objective: To assess the time needed and the resulting effects of a complete digitalisation of a radiological department of a major hospital (856 beds, 28,000 in-patients, 35,000 out-patients/year) a pilot study was performed. This had to be done without interrupting routine services.

Results: After intensive preparations were performed and the hospital-network was completed, within a two year period all radiological functions (mammography excluded), reporting stations and archives were changed to a complete digital workflow.

Electroporative fast pore-flickering of the annexin V-lipid surface complex, a novel gating concept for ion transport.

In contact with lipid bilayers and Ca2+-ions, the intracellular protein human annexin V (wild-type), Mr = 35,800, forms two types of cation-selective channels for the transport of Ca2+-, K+-, Na+- and Mg2+-ions, depending on the protein concentration [AN]. Type (I) channel events are large and predominant at high values [AN] > or = K = 5 nM at 296 K. At 50 mM Ca2+, symmetrical on both membrane sides, AN added at the cis side, the conductance is gCa(I) = 22 +/- 2 pS and at symmetrical 0.
