German Cardiac Arrest Registry: rationale and design of G-CAR.

Background: In Germany, 70,000-100,000 persons per year suffer from out-of-hospital cardiac arrest (OHCA). Despite medical progress, survival rates with good neurological outcome remain low. For many important clinical issues, no or only insufficient evidence from randomised trials is available.

Disk Battery Ingestion in a Toddler: Less Than Meets the Eye.

Background: Pediatric foreign-body ingestions are commonly managed by emergency physicians. Risk assessment and specific intervention are dependent on the nature and location of the foreign body. Radiographic evaluation is usually necessary to help define the clinical situation.

Expression patterns of Notch receptors and their ligands Jagged and Delta in human placenta.

The establishment of an appropriate fetomaternal vessel system is a prerequisite for prevention of pregnancy associated pathologies. Notch receptors and ligands are manifoldly involved in vascular development and angiogenesis. To further characterize the process of human placental vasculo- and angiogenesis we investigated the expression pattern of Notch receptors and their ligands during pregnancy.
