Patients with central airway obstruction (CAO) may need endobronchial intervention to relieve their symptoms. This report is on a single-center experience of using interventional bronchoscopy in terms of complications and survival. This retrospective study was conducted in a university hospital and involved 614 patients (464 men, 150 women; mean age, 60.2 years) with benign (n = 133) and malign...

Thermal decomposition of dolomite in the presence of CO2 in a calcination environment is investigated by means of in situ X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The in situ XRD results suggest that dolomite decomposes directly at a temperature around 700 °C into MgO and CaO. Immediate carbonation of nascent CaO crystals leads to the formation of calcite as an intermediate...

We hypothesized that the occurrence of spontaneous Ca2+ release from the sarcoplasmic reticulum (SR), in diastole, might be a mechanism for the saturation of twitch potentiation common to a variety of inotropic perturbations that increase the total cell Ca. We used a videomicroscopic technique in single cardiac myocytes to quantify the amplitude of electrically stimulated twitches and to monito...

Les travaux présentés dans cette thèse traitent de l’utilisation de la Réalité Virtuelle (RV) et plus particulièrement du retour d’effort pour améliorer l’interaction dans les applications de Conception Assistée par Ordinateur (CAO). Dans ce document, nous décrivons le rôle actuel du Product Lifecycle Management (PLM) dans l’industrie, et plus spécifiquement la place tenue par l’outil CAO. Celu...

and Implications Because treatment with calcium oxide (CaO) will increase the digestibility of corn stover, CaO-treated corn stover may be a cost-effective alternative to a portion of corn grain in beef feedlot diets. Single-pass harvested corn stover was ensiled either untreated or treated with 5% CaO on a dry matter (DM) basis. Ground baled stover, untreated stover silage, or CaO-treated stov...

We have used dialyzed squid axons to characterize the ouabain- and bumetanide-insensitive Na efflux components and their relation to the operation of the Na/Ca exchange mechanism. In axons dialyzed with solutions containing nearly physiological concentrations of K, Na, and Mg, three components of the Na efflux can be distinguished: Cai-activated, Cao-dependent Na efflux ("reverse" Na/Ca exchang...

The carrier effective masses of CaO in the cubic phase are estimated by ab initio calculations, which are used for the simulation of Si/CaO metal-oxide-semiconductor (MOS) devices by solving Schrödinger and Poisson equations self consistently. It is shown that higher switching speed, longer lifetimes, and higher endurance can be obtained replacing SiO2 by CaO as gate dielectric, suggesting prom...

The systolic and diastolic properties of single myocytes and intact papillary muscles isolated from hearts of adult rats and rabbits were examined at 37 degrees C over a range of stimulation frequencies and bathing [Ca2+]o (Cao). In both rabbit myocytes and intact muscles bathed in 1 mM Cao, increasing the frequency of stimulation from 6 to 120 min-1 resulted in a positive staircase of twitch p...

New shock-wave (Hugoniot) and release-adiabatic data for Feo.940 and CaO, to 230 and 175 GPa (2.3 and 1.75 Mbar) respectively, show that both oxides transform from their initial B1 (NaC1-type) structures at about 70 (* 10) GPa. CaO transforms to the B2 (CsC1-type) structure and FeO is inferred to do the same. Alternatively, FeO may undergo an electronic transition, but it probably does not disp...

One group of sequence variants of Epstein-Barr virus is characterized by a 10-amino-acid deletion within the CTAR-2 functional domain of the latent membrane protein, LMP1. A role for this deletion in enhancing the tumorigenicity of the viral oncogene in rodent fibroblasts was recently demonstrated. We examined the effect of this deletion upon LMP1 function in four human lymphoid cell lines by u...
