The inclusive single and double differential cross-sections for neutral and charged current processes with four-momentum transfer squared Q2 between 150 and 30 000 GeV2 and with Bjorken x between 0:0032 and 0:65 are measured in e+p collisions. The data were taken with the H1 detector at HERA between 1994 and 1997, and they correspond to an integrated(More)
BACKGROUND Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited disorder that causes sudden death and right ventricular heart failure in the young. Clinical data suggest that competitive sports may provoke ARVC in susceptible persons. Genetically, loss-of-function mutations in desmosomal proteins (plakophilin, desmoplakin, or plakoglobin)(More)
Measurement of myocardial perfusion is important for the functional assessment of heart in vivo. Our approach is based on the modification of the longitudinal relaxation time T1 induced by magnetic spin labeling of endogenous water protons. Labeling is performed by selectively inverting the magnetization within the detection slice, and longitudinal(More)
The purpose of the present study was the serial investigation of morphological and functional changes after left coronary artery ligation in the intact rat using cine-magnetic resonance imaging (MRI). MRI studies were performed 4, 8, 12, and 16 weeks after myocardial infarction (MI) with an echocardiogram (ECG)-triggered cine-fast low-angle shot(More)
BACKGROUND Identification of key molecular players in myocardial healing could lead to improved therapies, reduction of scar formation, and heart failure after myocardial infarction (MI). We hypothesized that clotting factor XIII (FXIII), a transglutaminase involved in wound healing, may play an important role in MI given prior clinical and mouse model(More)
PURPOSE To validate a magnetic resonance (MR) imaging technique that is not first pass and that reveals perfusion and regional blood volume (RBV) in the intact rat. MATERIALS AND METHODS Measurement of perfusion was based on the perfusion-sensitive T1 relaxation after magnetic spin labeling of water protons. RBV was determined from steady-state(More)
The purpose of this work was to develop high-resolution cardiac magnetic resonance imaging techniques for the in vivo mouse model for quantification of myocardial function and mass. Eight male mice were investigated on a 7-Tesla MRI scanner. High-quality images in multiple short axis slices (in-plane resolution 117 microm2, slice thickness 1 mm) were(More)
The aim of this study was to test the feasibility of cine magnetic resonance imaging (MRI) for assessment of the infarcted rat and mouse heart and to compare the results with established methods. These models have been proven to predict genesis and prevention of heart failure in patients. The value of cine MRI was tested in studies investigating(More)
The elastic electroproduction of ρ mesons is studied at HERA with the H1 detector for a photon virtuality in the range 1 < Q < 60 GeV and for a hadronic centre of mass energy in the range 30 < W < 140 GeV. The shape of the (ππ) mass distribution in the ρ resonance region is measured as a function of Q. The full set of ρ spin density matrix elements is(More)
The electroproduction of J/ψ and ψ(2S) mesons is studied in elastic, quasi-elastic and inclusive reactions for four momentum transfers 2 < Q < 80 GeV and photon-proton centre of mass energies 25 < W < 180 GeV. The data were taken with the H1 detector at the electron proton collider HERA in the years 1995 to 1997. The total virtual photon-proton cross(More)
