A 96-year-old woman developed hemiparesis 2 weeks after orthopedic surgery. Magnetic resonance imaging revealed multiple cerebral infarctions in the bilateral hemisphere. Transthoracic echocardiography revealed a mobile structure attached to the anterior mitral leaflet that protruded toward the left ventricular outflow tract. The structure was identified as an accessory mitral valve. Doppler ec...

A 46 year old man was found to have left ventricular outflow obstruction caused by a blood-filled cyst attached to the anterior papillary muscle of the mitral valve. It was successfully excised.

We present the results of far-infrared imaging of extended regions around three bipolar pre-planetary nebulae, AFGL 2688, OH 231.8+4.2, and IRAS 16342−3814, at 70 and 160 μm with the MIPS instrument on the Spitzer Space Telescope. After a careful subtraction of the point spread function of the central star from these images, we place constraints on the existence of extended shells and thus on t...

The sympathetic nervous system is widely assumed to respond to physiological challenges in a global and generalized manner.However,a number of observations have highlighted regional variations in the pattern of sympathetic outflow consequent to external stimuli, including electrical stimulation, thermal stimulation, acute exposure to hypoxia and injection of drugs (Futuro-Neto HA & Coote JH. 19...

PURPOSE The effect of total volume perfused on outflow resistance (the reciprocal of outflow facility) and the effect of age on the rate of change in resistance as a function of total volume were determined in rhesus and cynomolgus monkeys. METHODS Outflow facility was measured under general anesthesia by two-level constant pressure perfusion in one eye of 22 rhesus and 17 cynomolgus monkeys ...

Efferent vagal stimulation in the anesthetized dog with constant ventricular rate caused either no change in coronary sinus outflow and cardiac work, or a decrease in coronary sinus outflow associated with a greater decrease in cardiac work. When the decreases were observed they could best be explained by a negative inotropic effect of vagal stimulation on ventricular muscle, rather than by a d...

Autonomic activity affects beat-to-beat variability of heart rate and QT interval. The aim of this study was to explore whether entropy measures are suitable to detect changes in neural outflow to the heart elicited by two different stress paradigms. We recorded short-term ECG in 11 normal subjects during an experimental protocol that involved head-up tilt and mental arithmetic stress and compu...

Though widely observed to be emanatig out from a variety of galactic and extra-galactic sources, the underlying physical mechanism behind the formation of the cosmic jets and outflows are wrapped around by the veil of mistry till date. Neither the amount of matter contained in these jets could accurately be calculated by any definitive method as well. In this paper we present a theoretical mode...

Spectral analysis of heart rate variability has gained popularity as a simple, non-invasive tool for assessing autonomic function in both normal subjects and in patients in a variety of clinical settings. However, the use of this method as a means of estimating the magnitude of cardiac sympathetic activation in individual patients with heart failure has proved disappointing, with a lack of conc...
