OBJECTIVES: This study sought to establish whether the early favorable results in the Benestent-I randomized trial comparing elective Palmaz-Schatz stent implantation with balloon angioplasty in 516 patients with stable angina pectoris are maintained at 5 years. BACKGROUND: The size of the required sample was based on a 40% reduction in clinical events in the stent group. Seven months and one-year follow-up in this trial showed a decreased incidence of restenosis and clinical events in patients randomized to stent implantation. METHODS: Data at five years were collected by outpatient visit, via telephone and via the referring cardiologist. Three patients in the stent group and one in the percutaneous transluminal coronary angioplasty (PTCA) group were lost to follow-up at five years. Major clinical events, anginal status and use of cardiac medication were recorded according to the intention to treat principle. RESULTS: No significant differences were found in anginal status and use of cardiac medication between the two groups. In the PTCA group, 27.3% of patients underwent target lesion revascularization (TLR) versus 17.2% of patients in the stent group (p = 0.008). No significant differences in mortality (5.9% vs. 3.1%), cerebrovascular accident (0.8% vs. 1.2%), myocardial infarction (9.4% vs. 6.3%) or coronary bypass surgery (11.7% vs. 9.8%) were found between the stent and PTCA groups, respectively. At five years, the event-free survival rate (59.8% vs. 65.6%; p = 0.20) between the stent and PTCA groups no longer achieved statistical significance. CONCLUSIONS: The original 10% absolute difference in TLR in favor of the stent group has remained unchanged at five years, emphasizing the long-term stability of the stented target site. [less ▲]

The aim of this paper is to show that the social coalition that benefited from India’s central government’s economic policies remained unchanged between the pre and post economic reforms periods. More specifically, this paper will argue that the economic policies promoted by the central government between 1980 and 2004 – irrespective of the political party heading the Cabinet – mostly benefited the middle class and the corporate sector, while the poor and the rural world were clearly relegated to a secondary position in the governments’ policy priorities. The paper will highlight six important lines of continuity in India’s economic policy and will argue that if we look at who the “winner” and the “losers” of these policy processes are, the economic reforms of the early 1990s do not separate two different phases of India’s development path. From this point of view the election of the United Progressive Alliance (UPA) government in 2004 might constitute a more important break with the past. [less ▲]

The maximum cross-correlation (MCC) method reconstructs the surface advective velocity fields from the displacements of spatial patterns in pairs of sequential satellite (normally infrared) images. However, the performance of the conventional MCC method is not always satisfactory. One of the main reasons for this is the fact that the method can correctly estimate only the velocity component parallel to the gradient of the property depicted in the images, while any small displacement perpendicular to the gradient (i.e., directed along the isolines) essentially maps the spatial pattern onto itself and therefore can not be detected using the conventional MCC technique. In the present work we propose a modification of the MCC method that allows circumventing this basic deficiency and improving the performance of the MCC technique. In this approach, the "cross-isoline'' components of the velocity field are obtained as in the conventional MCC scheme; however, the "along-isoline'' components derived from the MCC are disregarded as unreliable. Instead, the "true'' along-isoline components are then reconstructed from the given cross-isoline velocity field based on the continuity requirement and on the condition of no normal flow at solid boundaries. This inverse problem is solved by constructing the two-dimensional stream function in the curvilinear coordinate frame associated with the image isolines. The method is illustrated using AVHRR images from the southwestern Atlantic Ocean and the Black Sea. The results are compared with some direct drifter and current meter measurements and geostrophic estimates. [less ▲]

Near infrared spectroscopy (NIRS) was used to detect changes in brain oxygenation in five tranquilised calves that were placed on a hypoxic gas mixture (10 per cent O2/90 per cent N2) and hyperoxic gas mixture (30 per cent O2/70 per cent N2) for five minutes at each concentration. A NIRO 500 (Hamamatsu, Japan) was used for the NIRS, with the incident light source and separate detector (optodes) placed on shaved skin on the most dorsal surface of the frontal bone. Sequential arterial blood gas sample analyses provided confirmation of the appropriate change in systemic oxygenation status. By the end of the five-minute-period of breathing 10 per cent oxygen, NIRS of the calf head detected highly significant changes in haemoglobin oxygenation reflective of hypoxaemia, with oxyhaemoglobin decreasing by 23.5 units (P<0.01) and deoxyhaemoglobin increasing by 45.6 units, (P<0.01) from the baseline of breathing room air. Total haemoglobin (oxyhaemoglobin + deoxyhaemoglobin) showed a significant increase of 22.1 units (P<0.05) but there was no significant change in NIRS determined cytochrome aa3 oxygenation. Concomitant blood gas alterations included significant decreases in PaO2 (-27.8 mmHg, P<0.01), haemoglobin saturation (-29.0 per cent, P<0.05), and PaCO2 (-7.8 mmHg, P<0.05) and significantly increased blood pH (0.059, P<0.05). At the end of the five minutes of breathing 30 per cent oxygen NIRS of the calf head detected significantly increased oxyhaemoglobin (13.1 units, P<0.01) and decreased deoxyhaemoglobin (-13.7 units, P<0.05) when compared with baseline breathing of room aim. Total haemoglobin and cytochrome aa3 were unchanged from baseline. The accompanying arterial blood gas changes included significant increases in PaO2 (30.9 mmHg, P<0.05), arterial O2 saturation (11.7 per cent, P<0.05), and significantly decreased pH (-0.026, P<0.05). This study showed that NIRS can be used to continuously and non-invasively detect cerebral oxygenation changes in the live calf in response to both increased and decreased systemic arterial oxygen. Additionally, despite induction of profound hypoxaemia, cytochrome aa3 in the brain did not appear to become reduced. [less ▲]

Background - Diminished aortic flow may induce adverse downstream vascular and renal signals. Investigations in a heart failure animal model have shown that continuous aortic flow augmentation ( CAFA) achieves hemodynamic improvement and ventricular unloading, which suggests a novel therapeutic approach to patients with heart failure exacerbation that is inadequately responsive to medical therapy. Methods and Results - We studied 24 patients ( 12 in Europe and 12 in the United States) with heart failure exacerbation and persistent hemodynamic derangement despite intravenous diuretic and inotropic and/or vasodilator treatment. CAFA ( mean +/- SD 1.34 +/- 0.12 L/min) was achieved through percutaneous ( n = 19) or surgical ( n = 5) insertion of the Cancion system, which consists of inflow and outflow cannulas and a magnetically levitated and driven centrifugal pump. Hemodynamic improvement was observed within 1 hour. Systemic vascular resistance decreased from 1413 +/- 453 to 1136 +/- 381 dyne (.) s (.) cm(-5) at 72 hours ( P = 0.0008). Pulmonary capillary wedge pressure decreased from 28.5 +/- 4.9 to 19.8 +/- 7.0 mm Hg ( P < 0.0001), and cardiac index ( excluding augmented aortic flow) increased from 1.97 +/- 0.44 to 2.27 +/- 0.43 L (.) min(-1) (.) m(-2) ( P = 0.0013). Serum creatinine trended downward during treatment ( overall P = 0.095). There were 8 complications during treatment, 7 of which were self-limited. Hemodynamics remained improved 24 hours after CAFA discontinuation. Conclusions - In patients with heart failure and persistent hemodynamic derangement despite intravenous inotropic and/or vasodilator therapy, CAFA improved hemodynamics, with a reduction in serum creatinine. CAFA represents a promising, novel mode of treatment for patients who are inadequately responsive to medical therapy. The clinical impact of the observed hemodynamic improvement is currently being explored in a prospective, randomized, controlled trial. [less ▲]

The growth phase of substorms is characterized by equatorward motion of the auroral oval as manifested by optical emissions and the electrojet currents detected on the ground through magnetic perturbations. We will demonstrate the use of an inversion procedure for magnetic data that follows the optical borders detected in the CANOPUS Churchill meridian well. Multispectral meridian scanning photometry allows identification of 486 nm H-beta emission with the equatorward edge of the evening sector growth phase electrojet, consistent with downward field-aligned current at this location. The 630 nm and 557 nm emissions due to the precipitation of electrons are identified with the more poleward regions or the poleward border, and upward field-aligned current. While these results are already known, the use of magnetic data is a new way of continuously monitoring growth phase. The identifications are supported by satellite imaging from Image and POLAR in individual cases. Despite separation of the proton and electron emissions as observed from the ground, our results are consistent with the polar cap boundary determined using proton imaging by SI12 on Image. We have also confirmed precipitation region and FAC coincidence using FAST, and corrected the electrojet position when FAST did not fly directly over the ground array, based on imaging from the high altitude satellites.

We study the problem of finding a local minimum of a multilinear function E over the discrete set {0, 1}(n). The search is achieved by a gradient-like system in [0, 1](n) with cost function E. Under mild restrictions on the metric, the stable attractors of the gradient-like system are shown to produce solutions of the problem, even when they are not in the vicinity of the discrete set {0, 1}(n). Moreover, the gradient-like system connects with interior point methods for linear programming and with the analog neural network studied by Vidyasagar (IEEE Trans. Automat. Control 40 (8) (1995) 1359), in the same context. (C) 2004 Elsevier B.V. All rights reserved. [less ▲]

The visual continua in the spectra of three nebulae photographed with a narrow slit are not produced by the blending of atomic emission lines but must have a physical origin. Several strong He I emission lines just beyond the Balmer limit may tend to vitiate measurements of the intensity distribution in the Balmer continuum on plates taken with a wide slit. [less ▲]

This paper deals with the simulation of two extrusion tests by thixoforming: a non stationary extrusion test and a double-cup extrusion test. The simulations are based on a thermo-mechanical one-phase constitutive law that has been presented in details in several previous papers. A campaign of experimental extrusion testing has been conducted on a steel alloy and the comparison between the numerical and experimental results will validate the model under study. A new feature that has been added to the model is also discussed: the introduction of the phase change thermal effects such as the fusion latent heat and the contraction of the material [less ▲]
