OBJECTIVE During hypoxia, active substances released by the endothelium play a key role in the cardiovascular and respiratory responses elicited to optimize oxygen delivery. As hypercholesterolemia is a major cause of endothelial dysfunction, it may interfere with these responses. METHODS AND RESULTS We studied cardiovascular and ventilatory responses to acute systemic hypoxia in 14 patients ...
The algebra su 2 is derived from two commuting quon algebras for which the parameter q is a root of unity. This leads to a polar decomposition of the shift operators J + and J − of the group SU 2 (with J + = J † − = HUr where H is Hermitean and Ur unitary). The Wigner-Racah algebra of SU 2 is developed in a new basis arising from the simultanenous diagonalization of the commuting operators J 2 ...
PURPOSE The aim of this retrospective study was to assess the utility of a voxel-based analysis (VBA) method for (201)Tl SPECT in glioma, compared to conventional ROI analysis. METHODS We recruited 24 patients with glioma (high-grade 15; low-grade 9), for whom pre-operative (201)Tl SPECT and MRI were performed. SPECT images were coregistered with MRI. The uptake ratio (UR) images of tumor to ...
The easily prepared complex AuCl(PPh(2)Ur) (Ur = uracil) self-assembles in the solid state to form crystals containing solvent-accessible channels, the structure remains crystalline even after removal and re-addition of solvent.
This study identified the role of milling and parboiling on arsenic (As) content its species in large numbers rice samples. Total As contents were 108 ± 33 μg/kg polished grains (PR), 159 46 unpolished (UR), 145 42 parboiled (PPR) 44 (PUR). The percentages inorganic (iAs) 66% 8% PR from 72% to 77% other grain categories. polishing process reduced grains, removing outer part UR with high amount ...
I point out that if one defines the operator UR(t) as done by M. Znojil in his reply [arXiv:0711.0514v1] to my comment [arXiv:0711.0137v1] and also accepts the validity of the defining relation of UR(t) as given in his paper [arXiv:0710.5653v1], one finds that the time-evolution of the associated quantum system is not governed by the Schrödinger equation for the Hamiltonian operator H but an op...
INTRODUCTION While the readmission rate from community hospitals is known, the factors affecting it are not. Our aim was to determine the factors predicting unplanned readmissions from community hospitals (CHs) to acute hospitals (AHs). MATERIALS AND METHODS This was an observational prospective cohort study, involving 842 patients requiring post-acute rehabilitation in 2 CHs admitted from 3 ...

We present the interest of the Semantic Web techniques, particularly semantic annotation, in the biochip domain. We propose a semi-aut...
In modern fundamental theories there is consideration of higher dimensions, often in the context of what can be written as a Schrödinger equation. Thus, the energetics of bound states in different dimensions is of interest. By considering the quantum square well in continuous D dimensions, it is shown that there is always a bound state for 0 < D ≤ 2. This binding is complete for D → 0 and expon...
