A survey for molecular outflows was carried out by mapping the CO line toward a sample of 69 J p 2–1 luminous IRAS point sources. Sixty objects have IRAS luminosities from 10 to 10 L, and are associated with dense gas traced by NH3, identifying them as high-mass star-forming regions. Among 69 sources, 65 sources have data that are suitable for outflow identification. Thirty-nine regions show sp...

Premature ventricular contractions originating in the right ventricular outflow tract may respond poorly to pharmacological treatment, and ablation using conventional fluoroscopically-guided systems may be complicated by the difficulty in inducing arrhythmias. We describe the use of a non-contact mapping system to ablate difficult-to-induce premature ventricular contractions originating in the ...

The aim of the study was to quantitatively predict the clearance of three antibiotics, amikacin, vancomycin, and teicoplanin, during continuous hemodiafiltration (CHDF) and to propose their optimal dosage in patients receiving CHDF. For this goal, in vitro CHDF experiments with a polyacrylonitrile (PAN) membrane were first performed using these antibiotics, and then the clearances were compared...

While autonomic outflow is an important co-factor of nausea physiology, central control of this outflow is poorly understood. We evaluated sympathetic (skin conductance level) and cardiovagal (high-frequency heart rate variability) modulation, collected synchronously with functional MRI (fMRI) data during nauseogenic visual stimulation aimed to induce vection in susceptible individuals. Autonom...

'1-albumin was used to determine the rate of bulk outflow from the anterior chamber in one eye and I-albumin was used in the other. In 16 eyes at a spontaneous intraocular pressure of 8.0 ± 0.7 mm. Hg, uveoscleral flow was 0.63 ± 0.08 nL per minute and flow by fast, vascular routes was 0.53 ± 0.07 fiL per minute. When the intraocular pressure was lowered to 2 or 4 mm. Hg by letting aqueous flow...

We report on the first dedicated monitoring campaign of spectroscopic variability in young brown dwarfs. High-resolution optical spectra of six targets in nearby star-forming regions were obtained over 11 nights between 2005 JanuaryMarch on the Magellan 6.5m telescope. We find significant variability in Hα and a number of other emission lines related to accretion and outflow processes on a vari...

Fixed performance venturi devices should provide a predetermined oxygen concentration at an outflow which exceeds an adult's peak resting inspiratory flow rate (approximately 30 l.min(-1)). Campbell's original description mentioned the sensitivity of the venturi device to downstream resistance but gave no further details. This study examined outflow and oxygen concentration from the five standa...

Changes in outflow facility and in the content of norepinephrine in the iris and ciliary processes of the rabbit eye have been followed at early and late intervals after cervical ganglionectomy. Outflow facility was measured in vivo with a constant rate infusion technique. Norepinephrine tissue levels ivere determined by fluorescence spectrometry. The results indicate that the "early" increase ...

Ground water flow was investigated at Clear Lake, a 1468-ha glacial lake in north-central Iowa, as part of a comprehensive water quality study. A multiscale approach, consisting of seepage meters (and a potentiomanometer), Darcy's law, and an analytic element (AE) model, was used to estimate ground water inflow to and outflow from the lake. Estimates from the three methods disagreed. Seepage me...

We report a patient with profound hypovolemia who developed dynamic left ventricular outflow tract obstruction and severe mitral regurgitation. Both the outflow tract obstruction and mitral regurgitation resolved with volume replacement. Unlike previous reports of dynamic left ventricular outflow obstruction and mitral regurgitation, the degree of mitral regurgitation was severe. Possible mecha...
