Background—Mechanical chest compression (CC) is currently suggested to deliver sustained high-quality CC in a moving ambulance. This study compared the hemodynamic support provided by a mechanical piston device or manual CC during ambulance transport in a porcine model of cardiopulmonary resuscitation. Methods and Results—In a simulated urban ambulance transport, 16 pigs in cardiac arrest were ra

Background: Experimental active compression-decompression (ACD) CPR is associated with increased haemodynamic outcomes compared to standard mechanical chest compressions. Since no clinically available mechanical chest compression device is capable of ACD-CPR, we modified the LUCAS 2 (Physio-Control, Lund, Sweden) to deliver ACD-CPR, hypothesising it would improve haemodynamic outcomes compared wit

A precision luminosity measurement is of critical importance for the ATLAS physics program, both for searches for new physics as well as for precision measurements of Standard Model crosssections. The calibration of the luminosity is based on so-called van der Meer scans. The calibration determines the convolved beam sizes in the vertical and horizontal directions, and together with the precise kn

Self-treatment techniques in patients with paroxysmal atrial fibrillation (PAF) have seldom been described. It has been suggested that PAF attacks might be initiated by changes in the tonus of the autonomic nervous system. Our aim was to study patients’ measures to terminate PAF attacks and to evaluate the possible influence of the autonomic nervous system on start and stop mechanisms.

Late Quaternary sedimentary units at Kongsfjordhallet, NW Svalbard, represent five cycles of glaciations and subsequent deglaciations during high relative sea levels. The high sea level events are interpreted as glacioisostatically induced and imply preceding regional glaciations, which we constrain in time by luminescence and radiocarbon ages to just prior to ~ 195, ~ 130, ~ 85, ~ 60, and ~ 15 ka

Cultured rat hepatocytes release the enzyme hepatic lipase. In this study we investigated the effect of cell density on this metabolic function under a variety of experimental conditions. The release of hepatic lipase from cultured rat hepatocytes exhibits a cell-density dependence, the secretion per mg cell protein being increased with increasing cell density. When cell density dependence was tak

Rat hepatocyte monolayers were cultured in the presence of 1-10% lipoprotein-deficient foetal calf serum. This increased the uptake and degradation of chylomicron remnant cholesteryl ester significantly. The increase occurred at all cell densities, i.e. also with less dense cultures where the basal rate of uptake per mg protein was highest. This indicates that tissue culture medium content of lipo

In April of 2004, about a year after the start of the Iraq War, a story broke in the American media about the abuse of Iraqi detainees by American soldiers at the Abu Ghraib prison outside Baghdad.1 From the beginning, editorialists and science writers noted affinities between what happened at Abu Ghraib and Philip Zimbardo’s 1971 Stanford Prison Experiment.2 Zimbardo’s experiment is part of a bod
