Superoxide reductase SOR is an enzyme involved in superoxide detoxification in some microorganisms. Its active site consists of a non-heme ferrous center in an unusual [Fe(NHis)(4) (SCys)(1)] square pyramidal pentacoordination that efficiently reduces superoxide into hydrogen peroxide. In previous works, the reaction mechanism of the SOR from Desulfoarculus baarsii enzyme, studied by pulse radi...

Purpose. (124)I has a half-life of 4.2 days, which makes it suitable for imaging over several days over its uptake and washout phases. However, it has a low positron branching ratio (23%), because of prompt gamma coincidence due to high-energy γ-photons (602 to 1,691 keV), which are emitted in cascade with positrons. Methods. In this study, we investigated the optimal PET energy window for (124...

OBJECTIVE About one in every three employees seen by their occupational physician is absent from work because of psychosocial health complaints. To implement preventive measures, it is necessary to identify predictors for this type of sickness absence. STUDY DESIGN AND SETTING A meta-analysis was carried out to quantify the association between predictive factors and psychosocial sickness abse...

Dr. Linus Pauling noted that vitamin C is a critically important water-soluble antioxidant, as it protects proteins and lipids from free radical damage associated with infection, intensive exercise, and other stres-sors that can injure cells.1-3 These very properties make vitamin C a valuable agent for improving immune function. By suppressing oxidative stress, vitamin C increases the life span...

In order to reduce remote memory accesses on CC-NUMA multiproces-sors, we present an interprocedural analysis to support static loop scheduling and data allocation. Given a parallelized program, the compiler constructs graphs which represent globally and interprocedurally the remote reference penalties associated with diierent choices for loop scheduling and data allocation. After deriving an o...

In this article we present a generalized version of the Cross Approximation for 3d-ten-sors. The given tensor a ∈ R n×n×n is represented as a matrix of vectors and 2d adaptive Cross Approximation is applied in a nested way to get the tensor decomposition. The main focus lies on theoretical issues of the construction such as the desired interpolation property or the explicit formulas for the vec...

Solids of revolution (vases, bottles, bells, . . .), shortly SORs, are very common objects in man-made environments. We present a complete framework for 3D database population from a single image of a scene including a SOR. The system supports human intervention with automated procedures to obtain good estimates of the interest entities needed for 3D reconstruction. The system exploits the spec...
