We present high angular resolution observations toward two massive star forming regions IRAS 18264-1152 and IRAS 23151+5912 with the Plateau de Bure Interferometer (PdBI) in the SiO (J=2-1) and HCO (J=1-0) lines and at 1.3 mm and 3.4 mm continuum, and with the Very Large Array (VLA) in the NH3 (J,K)=(1,1), (2,2) lines. The NH3 (1,1) and (2,2) emission is detected toward IRAS 18264-1152 only. Fo...

AIMS Patients with heart failure (HF) show abnormal arterial stiffening. METHODS AND RESULTS We examined 60 patients (52.1 +/- 12, 8 years) with non-ischaemic dilated cardiomyopathy (NIDC), New York Heart Association II-III, in sinus rhythm, left ventricular ejection fraction 30.1 +/- 8.6%, and 44 normals. All subjects underwent an echocardiographic study and a cardiopulmonary exercise test. ...

We revisit the evaporation process of gas from dwarf galaxies after it has been photo-ionized by the UV flux from the first stars and AGNs and heated to T ≃ 10 or 2 × 10K respectively. Earlier estimates, based on the balance between pressure and gravity, indicated that dark haloes of virial velocity lower than Vevap ≃ 11−13 kms −1 have lost most of their gas in a dynamical time. We follow the c...

An approach of Green’s function is adopted to solve the inhomogeneous linear differential equations representing wave equations in piezo-composite materials. In particular, transference of horizontally polarised shear (SH) waves is considered in bedded structure comprising of porous-piezo electric layer lying over a heterogeneous half-space. Propagation of SH-waves is considered to be influence...

Objective: Increased pulse pressure (PP) has been associated with increased cardiovascular risk in persons with diabetes. Changes in central aortic properties can increase central PP and may adversely affect microvascular perfusion and cardiac performance. This study was performed to define early changes in central arterial properties in a group of young persons with type 1 diabetes mellitus (T...

background: although percutaneous coronary intervention (pci) is an excellent therapy for coronary artery disease, there is a paucity of information on the efficacy of pci in improving diastolic function, especially in iran. because of the high prevalence of left diastolic dysfunction in coronary artery disease patients and its probable progression to heart failure, an evaluation of the role of...

OBJECTIVE To assess longitudinal changes in systemic ventricular diastolic function late after the Fontan procedure. DESIGN AND PATIENTS Prospective study of 13 patients at 2.8 (2.0) years (early) and again at 11.4 (2.0) years (late) after the Fontan procedure by Doppler echocardiography with simultaneous ECG, phonocardiogram, and respirometer. SETTING Tertiary paediatric cardiac centre. ...

In front of the LMC molecular hydrogen is found in absorption near 0 kms, being local disk gas, near +60 kms in an intermediate velocity cloud, and near +120 kms, being a high velocity halo cloud. The nature of the gas is discussed based on four Orfeus far UV spectra of LMC stars and including data from the ground and from the IUE satellite. The local gas is cool and, given a span of sight line...
