The Intel iAPX 432 is an objectbased microcomputer which, together with its operating system iMAX, provides a multiprocessor computer system designed around the ideas of data abstraction, iMAX is implemented in Ada and provides, through its interface and facilities, an Ada view of the 432 system. Of paramount concern in this system is the uniformity of approach among the architecture, the operating system, and the language. Some interesting aspects of both the external and internal views of

Iterative reconstruction of the ultrasound attenuation coefficient from the backscattered radio-frequency signal

Natalia Ilyina, Jeroen Hermans, Erik Verboven, Koen Van Den Abeele, Emiliano D'Agostino, Jan D'hooge
2014 2014 IEEE International Ultrasonics Symposium  
Accurate estimation of the local acoustic attenuation based on the backscatter signal has several applications, e.g. ultrasound tissue characterization. Most of the existing techniques determine the attenuation coefficient of the tissue directly from the spectrum of the backscattered signal. In these approaches other effects, such as diffraction, that may influence the attenuation estimation should be corrected for. This correction may be impractical in vivo. In the present study the simulation

Indeed, the local attenuation coefficient was estimated by iteratively solving the forward wave propagation problem and matching the synthetic backscattered signal to the measured one. The proposed methodology was experimentally validated using tissuemimicking phantoms with different attenuation characteristics showing promising results.

The intracellular second messenger cGMP protects the heart under pathological conditions. We examined expression of phosphodiesterase 5 (PDE5), an enzyme that hydrolyzes cGMP, in human and mouse hearts subjected to sustained left ventricular (LV) pressure overload. We also determined the role of cardiac myocyte-specific PDE5 expression in adverse LV remodeling in mice after transverse aortic constriction (TAC). Methodology/Principal Findings: In patients with severe aortic stenosis (AS)

We observed robust expression in scattered cardiac myocytes of those AS patients with higher LV filling pressures and BNP serum levels. Following TAC, we detected similar, focal PDE5 expression in cardiac myocytes of C57BL/6NTac mice exhibiting the most pronounced LV remodeling. To examine the effect of cell-specific PDE5 expression, we subjected transgenic mice with cardiac myocyte-specific PDE5 overexpression (PDE5-TG) to TAC. LV hypertrophy and fibrosis were similar as in WT, but PDE5-TG had increased cardiac dimensions, and decreased dP/dt max and dP/dt min with prolonged tau (P,0.05 for all). Greater cardiac dysfunction in PDE5-TG was associated with reduced myocardial cGMP and SERCA2 levels, and higher passive force in cardiac myocytes in vitro. Conclusions/Significance: Myocardial PDE5 expression is increased in the hearts of humans and mice with chronic pressure overload. Increased cardiac myocyte-specific PDE5 expression is a molecular hallmark in hypertrophic hearts with contractile failure, and represents an important therapeutic target.

Matrix-Binding Vascular Endothelial Growth Factor (VEGF) Isoforms Guide Granule Cell Migration in the Cerebellum via VEGF Receptor Flk1

2010 Journal of Neuroscience  
Vascular endothelial growth factor (VEGF) regulates angiogenesis, but also has important, yet poorly characterized roles in neuronal wiring. Using several genetic and in vitro approaches, we discovered a novel role for VEGF in the control of cerebellar granule cell (GC) migration from the external granule cell layer (EGL) toward the Purkinje cell layer (PCL). GCs express the VEGF receptor Flk1, and are chemoattracted by VEGF, whose levels are higher in the PCL than EGL. Lowering VEGF levels in

Using GC-specific Flk1 knock-out mice, we provide for the first time in vivo evidence for a direct chemoattractive effect of VEGF on neurons via Flk1 signaling. Finally, using knock-in mice expressing single VEGF isoforms, we show that pericellular deposition of matrix-bound VEGF isoforms around PC dendrites is necessary for proper GC migration in vivo. These findings identify a previously unknown role for VEGF in neuronal migration.
