AbstractObjectiveIt is currently problematic to confirm the clinical diagnosis of glycine encephalopathy, requiring either invasive liver biopsy for enzymatic analysis of the glycine cleavage system or exhaustive mutation analysis. Because the glycine cleavage system breaks down glycine generating carbon dioxide, we suppose that the glycine cleavage system activity could be evaluated in vivo by measuring exhaled 13CO2 after administration of [1‐13C]glycine.MethodsThe [1‐13C]glycine breath test was performed in 10 control subjects and 5 glycine encephalopathy patients with GLDC mutation, including 1 patient with mild glycine encephalopathy.ResultsAll the patients showed lower 13CO2 excretion than any control subject.InterpretationNot only typical GE but also atypical GE can be reliably diagnosed by the 13C‐glycine breath test. Because it is rapid, non‐invasive, and requires little expertise, the breath test could be useful as a standard test for diagnosing GE. Ann Neurol 2006;59:862–867

AbstractObjectiveWe evaluated the correlation between intracranial (ICP) and intraocular pressure (IOP).MethodsOf the 77 patients who underwent a lumbar puncture, 27 were excluded secondary to a history of glaucoma, using drugs effective on IOP, and abnormal funduscopic examination. ICP was measured by lumbar puncture. IOP was measured by two scales of Schiotz tonometer in both eyes, and the mean was calculated.ResultsWe found a significant correlation between ICP and mean IOP (p < 0.001; r = 0.955). Body mass index, age, and disease type had no significant effect on this correlation.InterpretationIOP is correlated with ICP. Ann Neurol 2006;59:867–870

AbstractA series of tricyanovinyl (TCV)‐substituted oligothiophenes was synthesized and investigated with a number of physical methods including UV/Vis, IR, and Raman spectroscopy, nonlinear optical (NLO) measurements, X‐ray diffraction, and cyclic voltammetry. Mono‐ or disubstituted oligomers were prepared by the reaction of tetracyanoethylene with mono‐ or dilithiated oligomers. The comparative effects of the symmetric and asymmetric substitutions in the electronic and molecular properties have been addressed. These oligomers display dramatic reductions in both their optical and electrochemical band gaps in comparison with unsubstituted molecules. The analysis of the electronic properties of the molecules was assisted by density functional theory calculations, which are in excellent agreement with the experimental data. TCV substitution influences the energies of the frontier orbitals, especially with respect to the stabilization of LUMO orbitals. X‐ray structural characterization of a monosubstituted oligomer exhibits π‐stacking with favorable intermolecular interactions. NLO results agree with the role of the intramolecular charge‐transfer feature in the asymmetric samples. These results furthermore exalt the role of conformational flexibility in the disubstituted compounds and reveal an unexpected nonlinear optical activity for symmetric molecules. Regarding the electronic structure, the interpretation of the vibrational data reflects the balanced interplay between aromatic and quinoid forms, finely tuned by the chain length and substitution pattern. The electronic and structural properties are consistent with the semiconducting properties exhibited by these materials in thin film transistors (TFTs).

A Prospective Study of the Use of the [Os(tpy)2]2+ (tpy = 2,2′;6′:2″‐Terpyridine) Core as Signalling Scaffolding for the Development of Chemical Sensors
Authors: Ros‐Lis Jose V. , Martínez‐Máñez Ramón , Soto Juan , McDonagh Colette , Guckian Adrian 
Published: April 2006

AbstractThe heteroleptic osmium(II) complex [Os(L1)(Me‐phtpy)][PF6]2 (L1 = 1‐[4′‐p‐tolyl‐(2,2′:6′,2″‐terpyridyl)]‐1,4,8,11‐tetraazacyclotetradecane, Me‐phtpy = 4′‐p‐tolyl‐2,2′:6′,2″‐terpyridine) has been prepared, characterized and its potential use for chemical sensing purposes studied. The complex contains a polyazacycloalkane as “binding site” and a Os(tpy)22+ core that acts as a “signalling subunit”. The emission intensity of the osmium complex was quenched in acetonitrile/water (1:1 v/v) by Cu2+ and Ni2+. Potentiometric titrations of [Os(L1)(Me‐phtpy)]2+ in the presence of Cu2+ were carried out in order to determine thermodynamic binding constants in acetonitrile/water (70:30 v/v, 0.1 mol·dm–3 tetrabutylammonium perchlorate). With Cu2+ the receptor [Os(L1)(Me‐phtpy)]2+ forms the complex {Cu[Os(L1)(Me‐phtpy)]}4+ at neutral pH. Moreover it undergoes two stepwise protonation processes at acid pH related to the partial protonation of the cyclam core and forms two hydroxo complexes at basic pH. The Ni2+ complexes of the osmium receptor [Os(L1)(Me‐phtpy)]2+ are able to act as an anion fluorogenic chemosensor in acetonitrile/water mixtures. A displacement of the quenching effect to more acidic pH in the Ni2+–[Os(L1)(Me‐phtpy)]2+ system was observed for anions in the order ATP > AMP > chloride. A prospective study of the use of the [Os(L1)(Me‐phtpy)]2+ complex as a fluorogenic sensor for oxygen was also carried out by incorporation of the complex in sol‐gel silica films made with TEOS and MTEOS. Significant quenching of the osmium fluorescence by oxygen was observed. The oxygen response of the films showed good stability and repeatability. The study suggested that theOs(tpy)22+ core might act as suitable signalling scaffolding in chemical sensing systems of cations, anions and gases.(© Wiley‐VCH Verlag GmbH & Co.

Synthesis and Characterization of MoOI2(PMe3)3 and Use of MoOX2(PMe3)3 (X = Cl, I) in Controlled Radical Polymerization
Authors: Mata José A. , Maria Sébastien , Daran Jean‐Claude , Poli Rinaldo 
Published: April 2006

AbstractComplex MoOCl2(PMe3)3 smoothly reacts with NaI in acetone to produce MoOI2(PMe3)3 in good yields. The geometry of the compound is mer‐cis octahedral, that is, identical to that of the dichloride precursor, as shown by NMR spectroscopy and by an X‐ray crystallographic study. Electrochemical investigations of MoOX2(PMe3)3 show irreversible oxidation waves at Ep,a = +0.18 and +0.39 V for X = Cl and I, respectively. A study of the halide exchange between MoOCl2(PMe3)3 and NaI, or between MoOI2(PMe3)3 and Bu4NCl, shows two equilibrated isomers for the mixed halide intermediate MoOICl(PMe3)3. The diiodide complex rapidly exchanges the iodo ligands with chloride upon dissolution in chloroform at room temperature, and with bromide from (1‐bromoethyl)benzene (BEB) under more forcing conditions. The equilibrium favors the softer halide (I) on C and the harder one (Cl or Br) on MoIV. Both oxido compounds catalyze the atom transfer radical polymerization (ATRP) of styrene in combination with the BEB initiator, yielding polymers with quite narrow molecular weight distributions (down to 1.11). The apparent polymerization rate constant is approximately doubled in the presence of 1 equiv. of the Al(OiPr)3 cocatalyst. On the other hand, the system is not capable of efficiently controlling the radical chain growth for methyl acrylate polymerization. (© Wiley‐VCH Verlag GmbH & Co.

PDT‐associated host response and its role in the therapy outcome
Authors: Korbelik Mladen 
Published: April 2006

AbstractBackground and ObjectivesThe outcome of the treatment of solid tumors by photodynamic therapy (PDT) is critically dependent on the contribution from the host. This host response is provoked by the rapidly induced massive tumor tissue injury delivered by PDT that is experienced as a local trauma threatening the integrity and homeostasis at the affected site.Study Design/Materials and MethodsMouse tumor models were extensively employed in pre‐clinical studies investigating various aspects of host‐tumor interaction following PDT, but important input was also derived from clinical data.ResultsThe recognition of this PDT‐inflicted insult by innate immune sensors detecting danger signals from the distressed/altered tumor tissue, triggers host‐protecting responses dominantly manifested as acute inflammation that are elicited and orchestrated by the innate immune system. To secure the affected PDT‐targeted site, the inflammatory reaction attacks tumor vasculature and then neutralizes the focal source of danger signals by eliminating the injured tumor cells.ConclusionThe provoked highly intensified phagocytosis of dead tumor cells occurring in the context of a vigorous innate immune reaction emerges as a key factor responsible for the development of tumor antigen‐specific adaptive immune response that contributes to the eradication of PDT‐treated cancers.
