Abstract[MoCl2O2] catalyzes the hydrosilylation reaction of aldehydes and ketones, as well as the reduction of other related groups, in apparent contrast to its known behavior as an oxidation catalyst. In this work, the mechanism of this reaction is studied by means of density functional theory calculations using the B3LYP functional complemented by experimental data. We found that the most favorable pathway to the first step, the SiH activation, is a [2+2] addition to the MoO bond, in agreement with previous and related work. The stable intermediate that results is a distorted‐square‐pyramidal hydride complex. In the following step, the aldehyde approaches this species and coordinates weakly through the oxygen atom. Two alternative pathways can be envisaged: the classical reduction, in which a hydrogen atom migrates to the carbon atom to form an alkoxide, which then proceeds to generate the final silyl ether, or a concerted mechanism involving migration of a hydrogen atom to a carbon atom and of a silyl group to an oxygen atom to generate the silyl ether weakly bound to the molybdenum atom. In this MoVI system, the gas‐phase free energies of activation for both approaches are very similar, but if solvent effects are taken into account and HSiMe3 is used as a source of silicon, the classical mechanism is favored. Several unexpected results led us to search for still another route, namely a radical path. The energy involved in this and the classical pathway are similar, which suggests that hydrosilylation of aldehydes and ketones catalyzed by [MoCl2O2] in acetonitrile may follow a radical pathway, in agreement with experimental results.

Renal diagnosis of chronic hemodialysis patients with urinary tract transitional cell carcinoma in Taiwan
Authors: Chang Chung‐Hsin , Yang Cheng‐Ming , Yang An‐Hang 
Published: March 2007

AbstractBACKGROUND.Transitional cell carcinoma (TCC) is the most common malignancy in dialysis patients of Taiwan. The reason for such a high incidence of TCC is undetermined. The correlation between the underlying renal disease and the development of TCC was investigated.METHODS.The authors retrospectively reviewed the clinical data and outcome of 1537 chronic hemodialysis (HD) patients from 1993 to 2002. The incidence of TCC was computed. The Cox regression method was used to analyze the role of potential risk factors.RESULTS.After a mean dialysis duration of 46.5 months, 26 (1.69%) patients with TCC were diagnosed. The standardized incidence ratio (SIR) of TCC was 48.2 as compared with the general population and the SIR of TCC seemed higher in women (65.1) and in the age group 50 to 54 years (173.6). Of them, most cases showed no definite etiology. All these cases showed bilateral contracted kidneys. Nonnephrotic proteinuria was found in all cases and trace glucosuria was found in 17 (65%). Painless gross hematuria was the cardinal symptom and distant metastasis was rare. Also, TCC in upper urinary tracts were common and found in 14 (54%) of patients. Age at the time of dialysis, female sex, compound analgesic use, and Chinese herb use had statistical significance as risk factors (P < .05).CONCLUSIONS.Chronic HD patients have a high risk of TCC in Taiwan, especially in female and middle‐aged patients. The study indicated that chronic tubulointerstitial nephritis (CTIN) is the most likely underlying renal disease in HD patients with TCC, a high percentage of the CTIN related to the usage of Chinese herbs or compound analgesics may contribute to the development of TCC, whereas diabetes or chronic glomerulonephritis play only a minor role.

Mesoporous Pt–SiO2 and Pt–SiO2–Ta2O5 Catalysts Prepared Using Pt Colloids as Templates
Authors: Pârvulescu Vasile I. , Pârvulescu Viorica , Endruschat Uwe , Granger Pascal , Richards Ryan 
Published: February 2007

AbstractSol‐gel synthesis of silica and silica–tantalum oxide embedded platinum nanoparticles is carried out using Pt colloids as templates. These colloids are prepared by reduction with Na[AlEt3H] and stabilized with different ligands (ammonium halide derivatives, non‐ionic surfactants with polyether chains, and 2‐hydroxy‐propionic acid). The aim of the present study is to prepare mesoporous silica embedded Pt colloids combining the “precursor concept” with the model of catalyst preparation using preformed spheres. Nanoparticles of Pt incorporated in high surface area mesoporous materials are formed after calcination. Further, it is observed that calcination of these catalysts causes partial aggregation and oxidation of the parent colloids, a process that is largely dependent on the nature of the stabilizing ligands. Several methods have been used for characterization of these materials: adsorption‐desorption isotherms at 77 K, H2 chemisorption, X‐ray diffraction(XRD), 29Si and 13C magic angle spinning (MAS) NMR, ammonia diffuse reflectance Fourier transform infrared spectroscopy (NH3‐DRIFT), transmission electron microscopy (TEM), and X‐ray photoelectron spectroscopy (XPS). It is found that both metal oxide systems exhibit Brønsted acidity (weaker for silica and quite strong for silica–tantalum oxide). In addition, NH3‐DRIFT experiments demonstrate the oxidative properties of the surface. Part of the adsorbed NH4+ species is oxidized to N2O. Testing these catalysts in the reduction of NO and NO2 with isopentane under lean conditions indicate that the activity of these catalysts is indeed dependent on the size of the platinum particles, with those of size 8–10 nm demonstrating the best results. The support likely contributes to this effect, particularly after Ta incorporation into silica.
ICAM‐1 expression on conjunctival epithelial cells in patients with cystic fibrosis

Published: February 2007

AbstractBackground:Cystic fibrosis is one of the most common lethal genetic conditions. The defect is due to mutations in a gene on chromosome 7, named the cystic fibrosis transmembrane regulator (CFTR), which functions as a chloride channel in epithelial membranes It is presumed that the disease affects all secretory epithelia including the eye. The objective of this study is to investigate the expression of intercellular adhesion molecule‐1 (ICAM‐1) by conjunctival epithelial cells of patients with cystic fibrosis and the correlation between of the expression of ICAM‐1 and the grade of cystic fibrosis severity.Methods:Impression cytology specimens were collected in 24 patients with cystic fibrosis. Cells were processed for flow cytometry, by using monoclonal antibodies to ICAM‐1.Results:A significant increase of ICAM‐1 expression on epithelial cells was found in patients with cystic fibrosis when compared with normal eyes. A positive correlation between the ICAM‐1 expression and severe clinical status of CF patients was also observed.Conclusions:Our findings suggest that the inflammation appears to have a role in the pathogenesis of the ocular surface changes in patients with cystic fibrosis. ICAM‐1 expression on conjunctival epithelial cells may be a marker of the inflammatory status in cystic fibrosis patients. The method described here reveal good repeatability and reliability for the analysis of the inflammatory markers on conjunctival epithelial cells and can be a useful tool in evaluating of the ocular findings and treatment interventions in patients with cystic fibrosis. © 2007 Clinical Cytometry Society.
