OBJECTIVE Stretch induces functional and trophic effects in mammalian myocardium via various signal transduction pathways. We tested stretch signal transduction on immediate and slow force response (SFR) in rabbit myocardium. METHODS Experiments were performed in isolated right ventricular muscles from adult rabbit hearts (37 degrees C, 1 Hz stimulation rate, bicarbonate-buffer). Muscles were...

We study how interactions between galaxies affect star formation within them by considering a sample of almost 1500 of the nearest galaxies, all within a distance of ∼45 Mpc. We use the far-IR emission to define the massive star formation rate (SFR), and then normalise the SFR by the stellar mass of the galaxy to obtain the specific star formation rate (SSFR). We explore the distribution of (S)...

Deriving the Initial Mass Function and the Star Formation Rate (hereafter IMF and SFR) history of disc stars from local data implies assumptions concerning the vertical structure of the disc. Conversely, an accurate description of the vertical density of the stellar disc would require a precise knowledge of the stellar formation history. In this paper, the constraints available from local data ...

To assess the accuracy of positron emission tomography (PET) for evaluation of coronary artery disease (CAD), cardiac PET perfusion images were obtained at rest and with dipyridamole-handgrip stress in 193 patients undergoing coronary arteriography. PET images were reviewed by two independent readers blinded to clinical data. Subjective defect severity scores were assigned to each myocardial re...

We further the recent discussion on the relation between the star-formation rate (SFR) of a galaxy and the luminosity of its brightest star-cluster (SFR vs. M V ). We first show that the observed trend between SFR vs. M V is due to the brightest cluster in a galaxy being preferentially young (6 15 Myr for a constant SFR) and hence a good tracer of the current SFR, although we give notable excep...

The relation between the stellar mass (M⋆) and the star formation rate (SFR) characterizes how the instantaneous star formation is determined by the galaxy past star formation history and by the growth of the dark matter structures. We deconstruct the M⋆−SFR plane by measuring the specific SFR functions in several stellar mass bins from z = 0.2 out to z = 1.4 (specific SFR = SFR/M⋆, noted sSFR)...

Observations of star-forming galaxies at high z have suggested discrepancies in the inferred star formation rates (SFRs) either between data and models or between complementary measures of the SFR. These putative discrepancies could all be alleviated if the stellar initial mass function (IMF) is systematically weighted towards more high-mass star formation in rapidly star-forming galaxies. Here...

OBJECTIVE To determine whether a single-family room (SFR) NICU, including factors associated with the change to a SFR NICU, is associated with improved medical and neurobehavioral outcomes. METHODS Longitudinal, prospective, quasi-experimental cohort study conducted between 2008 and 2012 comparing medical and neurobehavioral outcomes at discharge in infants born <1500 g. Participants included...
