Published: December 2008

AbstractMany of the biological processes taking place in cells are mediated by enzymatic reactions occurring in the cell membrane. Understanding interfacial enzymatic catalysis is therefore crucial to the understanding of cellular function. Unfortunately, a full picture of the overall mechanism of interfacial enzymatic catalysis, and particularly the important diffusion processes therein, remains unresolved. Herein we demonstrate that single‐molecule wide‐field fluorescence microscopy can yield important new information on these processes. We image phospholipase enzymes acting upon bilayers of their natural phospholipid substrate, tracking the diffusion of thousands of individual enzymes while simultaneously visualising local structural changes to the substrate layer. We study several enzyme types with different affinities and catalytic activities towards the substrate. Analysis of the trajectories of each enzyme type allows us successfully to correlate the mobility of phospholipase with its catalytic activity at the substrate. The methods introduced herein represent a promising new approach to the study of interfacial/heterogeneous catalysis systems.
Pd/MOx Materials Synthesized by Sol‐Gel Coprecipitation as Catalysts for Carbon–Carbon Coupling Reactions of Aryl Bromides and Chlorides
Authors: Kleist Wolfgang , Lee Jae‐Kyu , Köhler Klaus 
Published: December 2008

AbstractIn order to control the interaction of palladium species with oxide supports, a sol‐gel coprecipitation synthesis has been developed for Pd/MOx. The resulting Pd/MOx catalysts are characterized by a rather strong interaction between the highly dispersed Pd2+ species and the alumina and silica lattices. During coupling reactions of the Heck type the catalytically active species is generated by partial dissolution of Pd from the support surface. Due to the strong bonding of Pd to the support this dissolution occurs to significant extent only at comparatively high temperatures (≥160 °C). These temperatures are exactly necessary for the activation of less‐reactive substrates like bromobenzene and aryl chlorides. In this way we are able to synthesize supported catalysts that facilitate a controlled release of soluble Pd species under reaction conditions that are required for the activation of aryl bromides and chlorides. The Pd/MOx catalysts show excellent activity in the Heck reaction of bromobenzene (TON up to 10000; TOF up to 5000 h–1) and 4‐chloroacetophenone (TON up to 9300; TOF up to 1550 h–1).(© Wiley‐VCH Verlag GmbH & Co.

Palladium(II) Complexes with Benzimidazolin‐2‐ylidene and Phosphane Ligands and their Catalytic Activity in Mizoroki–Heck Coupling Reactions
Authors: Türkmen Hayati , Pape Tania , Hahn F. Ekkehardt , Çetinkaya Bekir 
Published: December 2008

AbstractSymmetrically and unsymmetrically substituted benzimidazolium bromides (1a–d = NHC·HBr) were synthesized, incorporating bulky benzyl and/or methoxyethyl substituents (a: R = pentamethylbenzyl, R′ = 2‐methoxyethyl; b: R = 2,3,5,6‐tetramethylbenzyl, R′ = methoxyethyl; c: R, R′ = pentamethylbenzyl; d: R, R′ = 2,3,5,6‐tetramethylbenzyl). The salts were used to prepare NHC palladium complexes. Reaction of 1a–d with Pd(OAc)2 and NaBr in a 1:1:3 ratio in dmso gave mono or dinuclear, bromide‐bridged complexes of type 2. Complexes of type 2 react with monodentate or bidentate phosphanes in CH2Cl2 to afford the mixed benzimidazolin‐2‐ylidene‐phosphane complexes 3–6. Reaction of salts 1a–d with Pd(OAc)2 in a 1:2 ratio, in the absence of NaBr, gave complexes trans‐[PdBr2(NHC)2] (7). All compounds were fully characterized by NMR spectroscopy, mass spectrometry (MALDI), and elemental analysis. In addition, the molecular structures of 2c, 3c, 3d, and 5b were determined by X‐ray diffraction. The catalytic activities of 2–7 in Mizoroki–Heck C–C coupling reactions of aryl halides with n‐butyl acrylate are described and compared. (© Wiley‐VCH Verlag GmbH & Co.

On series solution for generalized Falkner–Skan flow of a FENE‐P model
Authors: Abbasbandy S. , Hayat T. , Maqbool K. 
Published: December 2008

AbstractThis paper deals with the viscoelastic boundary layer flow past a plate. Constitutive assumptions of the FENE‐P model are taken into account. The pressure gradient is taken as non‐zero. The series solution of the non‐linear problem modelled in (Appl. Math. Lett. 2007; 20:1211–1215) is developed by a homotopy analysis method (HAM). Numerical solution of the skin friction coefficient is also computed. Further a comparison between the numerical and HAM solutions is provided. Copyright © 2008 John Wiley & Sons, Ltd.
Circulating insulin‐like growth factor peptides and prostate cancer risk: A systematic review and meta‐analysis
Authors: Rowlands Mari‐Anne , Gunnell David , Harris Ross , Vatten Lars J. , Holly Jeff M.P. , Martin Richard M. 
Published: December 2008

AbstractInsulin‐like growth factors (IGF‐I, IGF‐II) and their binding proteins (IGFBP‐1–6) play a key role in cell proliferation, differentiation and apoptosis, suggesting possible involvement in carcinogenesis. Several epidemiological studies show associations of IGFs with prostate cancer. We searched the published literature for all studies relating levels of IGFs or IGFBPs with prostate cancer. We performed random effects meta‐analysis to calculate summary odds ratios. The number of studies (prostate cancer cases) included in each meta‐analysis were 42 (7,481) IGF‐I; 10 (923) IGF‐II; 3 (485) IGFBP‐1; 5 (577) IGFBP‐2; 29 (6,541) IGFBP‐3 and 11 (3,545) IGF‐1:IGFBP‐3 ratio. The pooled odds ratios (95% confidence intervals) per standard deviation increase in peptide were: IGF‐I, OR = 1.21 (1.07, 1.36); IGF‐II, OR = 1.17 (0.93, 1.47); IGFBP‐1, OR = 1.21 (0.62, 2.33); IGFBP‐2, OR = 1.18 (0.90, 1.54); IGFBP‐3, OR = 0.88 (0.79, 0.98); IGFI:IGFBP‐3 ratio, OR = 1.10 (0.97, 1.24). For all exposures, there was substantial heterogeneity (all I2 > 75%), partly explained by study design: the magnitude of associations was smaller in prospective vs. retrospective studies, and for IGFBP‐3, the inverse association with prostate cancer risk was seen in retrospective but not prospective studies. There was weak evidence that associations of IGF‐I and IGFBP‐3 with prostate cancer were stronger for advanced disease. Our meta‐analysis confirms that raised circulating lGF‐I is positively associated with prostate cancer risk. Associations between IGFBP‐3 and prostate cancer were inconsistent, and there was little evidence for a role of IGF‐II, IGFBP‐1 or IGFBP‐2 in prostate cancer risk. © 2008 Wiley‐Liss, Inc.
Boundary mode lubrication of articular cartilage by recombinant human lubricin
Authors: Gleghorn Jason P. , Jones Aled R.C. , Flannery Carl R. , Bonassar Lawrence J. 
Published: December 2008

AbstractLubrication of cartilage involves a variety of physical and chemical factors, including lubricin, a synovial glycoprotein that has been shown to be a boundary lubricant. It is unclear how lubricin boundary lubricates a wide range of bearings from tissue to artificial surfaces, and if the mechanism is the same for both soluble and bound lubricin. In the current study, experiments were conducted to investigate the hypothesis that recombinant human lubricin (rh‐lubricin) lubricates cartilage in a dose‐dependent manner and that soluble and bound fractions of rh‐lubricin both contribute to the lubrication process. An rh‐lubricin dose response was observed with maximal lubrication achieved at concentrations of rh‐lubricin greater than 50 µg/mL. A concentration–response variable‐slope model was fit to the data, and indicated that rh‐lubricin binding to cartilage was not first order. The pattern of decrease in equilibrium friction coefficient indicated that aggregation of rh‐lubricin or steric arrangement may regulate boundary lubrication. rh‐lubricin localized at the cartilage surface was found to lubricate a cartilage–glass interface in boundary mode, as did soluble rh‐lubricin at high concentrations (150 µg/mL); however, the most effective lubrication occurred when both soluble and bound rh‐lubricin were present at the interface. These findings point to two distinct mechanisms by which rh‐lubricin lubricates, one mechanism involving lubricin bound to the tissue surface and the other involving lubricin in solution. © 2008 Orthopaedic Research Society.

Enantioselective separation of chiral vicinal diols in capillary electrophoresis using a mono‐6A‐aminoethylamino‐β‐cyclodextrin as a chiral selector
Authors: Liu Peng , Sun Xiaoli , He Wei , Jiang Ru , Wang Pingan , Zhao Yan , Zhang Shengyong 
Published: December 2008

AbstractThis paper describes an improved access to mono‐6A‐aminoethylamino‐β‐CD (β‐CDen), a very efficient cationic chiral selector for CZE in the separation of eight chiral aromatic vicinal diols. The β‐CDen concentration has a strong influence on the efficiency of enantioseparation. The effects of the pH and concentration of the BGE, the capillary temperature, and the applied voltage on the resolution and separation selectivity have been studied. Excellent chiral resolution was achieved under the optimal conditions of β‐CDen 10 mM, pH 10, 200 mM borate buffer at 15 kV and 20°C within 20 min. Moreover, the developed method was successfully applied to the determination of the enantiomeric purity of the catalytic asymmetric dihydroxylation (AD) reaction products.
Hydrophobicity‐aided potentiometric detection of catecholamines, beta‐agonists, and beta‐blockers in a mixed‐solvent capillary electrophoresis system
Authors: Bazylak Grzegorz , Monge Maria Eugenia , Everaert Joseph , Nagels Luc Joseph 
Published: December 2008

AbstractA series of cationic drug‐like substances with distinct basicity, hydrogen‐bonding ability, and hydrophobicity, including three catecholamines, two beta‐agonists, and thirteen beta‐blockers, was successfully detected in a capillary electrophoresis system using an end‐capillary coupled potentiometric sensor consisting of a PVC‐based liquid membrane deposited directly on a 100 μm diameter copper rod. The electrophoretic separation was performed on a 72 cm×75 μm id uncoated fused‐silica capillary with an acidic background electrolyte containing phosphoric acid in a water–acetonitrile mixture, pH* 2.8. Samples were injected electrokinetically at 5.0 kV for 10 s and a running voltage of 19.5 kV was applied. Excluding the bufuralol/practolol pair, baseline separation of all substances was achieved in the developed CE system within 9 minutes. A linear relationship (R2 0.8752) between the sensitivity of the applied potentiometric detector and the parameter log P characterising the hydrophobicity of the analytes was demonstrated. The best observable limits of detection (LODs) were obtained for the highly hydrophobic substances, i. e. bufuralol (8.10×10–8 M injected concentration, S/N = 3), propranolol, alprenolol, and clenbuterol (ca. 1.10×10–7 M). In the case of hydrophilic catecholamines and carbuterol their LODs with potentiometric detection were lowered by a factor of almost one thousand, reaching a value of 6.6×10–5 M.
Primary mediastinal B‐cell lymphoma in the pediatric patient: Can a rational approach to therapy be based on adult studies?
Authors: Attias Dina , Hodgson David , Weitzman Sheila 
Published: December 2008

AbstractThe literature on adult and pediatric primary mediastinal B‐cell lymphoma (PMBCL) was reviewed and compared. Biologically, adult PMBCL has more similarities to Hodgkin Lymphoma (HL) than diffuse large B‐cell lymphoma (DLBCL). Pediatric studies suggest that the biology is similar to that in adults. Median age of children is 14.3 years and the overall survival (OS) is reported as 78.6% and event‐free survival (EFS) as 67.4%. Adverse prognostic factors included LDH >500 and mass size over 10 cm, with a trend towards better survival in younger patients. Studies in adults show better survival with intensified chemotherapy and the addition of rituximab. Data on the use of radiation therapy show improved CR rates and survival with addition of involved field radiation therapy (IFRT). Positron emission tomography (PET) with computerized tomography (CT) imaging response‐assessment after two courses and at therapy‐end may allow for the rational use of IFRT in pediatric/adolescent patients who are more susceptible to development of adverse late effects.
