Sur 2601 admissions, chez 113 enfants at­teints de la maladie de Bouillaud, hospitalises en cinq ans dans deux services de pediatrie de Te­heran (C.H.U. de Pahlavi, C.H.U. de Logman­doleh Adham) 6 cas de manifestations cutanees  (trois cas de nodules, trois cas d'erytheme mar­ginatum) ont ete constates, trois d'entre eux souffrant d'une cardite severe et evolutive.  En Iran !'incidence des si...

 O S S 2 1 2 1 for each operator  O, henceforth denotes as O(2S+1Ξ ), are calculated using the GAMESS package.40 We use both Hartree-Fock (HF) method and complete active space self-consistent field (CAS-SCF) method. Our CAC-SCF many-evectron wavefunctions contain configuration interactions among the 3s and 3p valence shell and empty 3d-derived orbitals: CAS(6,26) and CAS(9,18) for Al2 and Al3...

Filmes reticulados de gelatina (Gel), caseína (Cas) e a mistura Gel/Cas (1:1, m/m) foram estudados em termos das propriedades térmicas, morfológicas e absorção de água e quanto ao perfil de permeação de p-hidroxiacetanilida (p-HAA ) como fármaco modelo. O grau de reticulação por 1-etil-3-(3-cloridrato) dimetilaminopropil carbodiimida (EDC) foi de 90,6% para filmes de Gel e cerca de 70% para fil...

The Arabidopsis calcium-sensing receptor CAS is a crucial regulator of extracellular calcium-induced stomatal closure. Free cytosolic Ca(2+) (Ca(2+)(i)) increases in response to a high extracellular calcium (Ca(2+)(o)) level through a CAS signalling pathway and finally leads to stomatal closure. Multidisciplinary approaches including histochemical, pharmacological, fluorescent, electrochemical,...

The snapshot problem was first proposed over a decade ago [1, 2] and has since been well-studied in the distributed algorithms community [4, 5, 6, 7, 8, 9, 12, 13, 14, 17, 18]. The challenge is to design a data structure consisting of m components, shared by upto n concurrent processes, that supports two operations. The first, Update(i, v), atomically writes v to the ith component. The second, ...

To probe increased O-GlcNAc levels as an independent mechanism governing insulin resistance in 3T3-L1 adipocytes, a new class of O-GlcNAcase (OGA) inhibitor was studied. 6-Acetamido-6-deoxy-castanospermine (6-Ac-Cas) is a potent inhibitor of OGA. The structure of 6-Ac-Cas bound in the active site of an OGA homolog reveals structural features contributing to its potency. Treatment of 3T3-L1 adip...

Plants produce cyanide (CN-) during ethylene biosynthesis in the mitochondria and require β-cyanoalanine synthase (CAS) for CN- detoxification. Recent studies show that CAS is a member of the β-substituted alanine synthase (BSAS) family, which also includes the Cys biosynthesis enzyme O-acetylserine sulfhydrylase (OASS), but how the BSAS evolved distinct metabolic functions is not understood. H...

Plants produce cyanide (CN2) during ethylene biosynthesis in the mitochondria and require b-cyanoalanine synthase (CAS) for CN2 detoxification. Recent studies show that CAS is a member of the b-substituted alanine synthase (BSAS) family, which also includes the Cys biosynthesis enzyme O-acetylserine sulfhydrylase (OASS), but how the BSAS evolved distinct metabolic functions is not understood.
