A record of atmospheric carbon dioxide (CO2) concentration during the transition from the Last Glacial Maximum to the Holocene, obtained from the Dome Concordia, Antarctica, ice core, reveals that an increase of 76 parts per million by volume occurred over a period of 6000 years in four clearly distinguishable intervals. The close correlation between CO2(More)
A high–resolution record of the atmospheric CO2 concentration from 60 to 20 thousand years before present (kyr BP) based on measurements on the ice core of Taylor Dome, Antarctica is presented. This record shows four distinct peaks of 20 parts per million by volume (ppmv) on a millennial time scale. Good correlation of the CO2 record with temperature(More)
OBJECTIVES The aim of this study was to compare fully quantitative cardiovascular magnetic resonance (CMR) and positron emission tomography (PET) myocardial perfusion and myocardial perfusion reserve (MPR) measurements in patients with coronary artery disease (CAD). BACKGROUND Absolute quantification of myocardial perfusion and MPR with PET have proven(More)
BACKGROUND The benefit of the coronary collateral circulation (natural bypass network) on survival is well established. However, data derived from smaller studies indicates that coronary collaterals may increase the risk for restenosis after percutaneous coronary interventions. The purpose of this systematic review and meta-analysis of observational studies(More)
Patients with SLE suffer from accelerated atherosclerosis due to systemic inflammation. We examined subclinical coronary artery involvement in patients with systemic lupus erythematous (SLE) by contrast enhanced inversion recovery (CE-IR) coronary magnetic resonance imaging.
OBJECTIVES This study investigated the feasibility of visual and quantitative assessment of coronary vessel wall contrast enhancement (CE) for detection of symptomatic atherosclerotic coronary artery disease (CAD) and subclinical coronary vasculitis in autoimmune inflammatory disease (systemic lupus erythematosus [SLE]), as well as the association with(More)
Wagner et al. (1) present a high-resolution record of leaf stomatal index (SI), from which they reconstruct the concentration of atmospheric CO 2 in the early Holocene (10,070 to 9,380 14 C-yr BP, 11,300 to 10,600 cal yr BP) (1, 2). The resulting record shows a CO 2 concentration of about 270 ppmv at 11,300 yr BP, a sharp increase to about 330 ppmv at(More)
Out-of-hospital cardiac arrest (OHCA) has attracted increasing attention over the past years because outcomes have improved impressively lately. The changes for neurological intact outcomes has been poor but several areas have achieved improving survival rates after adjusting their cardiac arrest care. The pre-hospital management is certainly key and(More)
and to the warming interval after the ACR in Antarctica. Data from Vostok suggest an important role of the Southern Ocean in regulating the glacial-interglacial CO 2 changes (5). This role is confirmed by measurements from Tay-lor Dome for shorter time intervals in the last glaciation (16). The CO 2 increase in interval I, which occurred before any(More)
