Published: August 2009

Objective: The aim of this study is to investigate the feasibility of using a 6.5 Fr sheathless guide catheter as a default system in transradial (TRA) percutaneous coronary intervention (PCI). Background: TRA PCI has been shown to reduce mortality rates through a reduction in access site related bleeding complications compared with procedures performed though a femoral approach. Complications associated with the TRA route increase with the size of sheath used. These complications may be reduced by the use of a sheathless guide catheter system (Asahi Intecc, Japan) that is 1–2 Fr sizes smaller in diameter than the corresponding introducer sheath. Methods: We performed PCI in 100 consecutive cases using 6.5 Fr sheathless guides to determine the procedural success, rates of symptomatic radial spasm and radial occlusion. Results: Procedural success using the 6.5 Fr sheathless guide catheter system was 100% with no cases requiring conversion to a conventional guide and catheter system. There were no procedural complications recorded associated with the use of the catheter. Adjunctive devices used in this cohort included IVUS, stent delivery catheters, distal protection devices, and simple thrombectomy catheters. The rate of radial spasm was 5% and the rate of radial occlusion at 2 months was 2%. Conclusion: Use of the 6.5 Fr sheathless guide catheter system, which has an outer diameter <5 Fr sheath, as the default system in routine PCI is feasible with a high rate of procedural success via the radial artery. © 2009 Wiley‐Liss, Inc.
Catalytic Combustion of Toluene over a Copper‐Manganese‐Silver Mixed‐Oxide Catalyst Supported on a Washcoated Ceramic Monolith
Authors: Zhou J.‐C. , Wu D.‐F. , Jiang W. , Li Y.‐D.
Published: August 2009

Monolithic catalysts were prepared by washcoating an alumina sol and then impregnating Cu‐Mn‐Ag mixed oxides onto cordierite substrates. The effects of the preparation parameters including the Ag/Cu/Mn ratio, the total amount of active phase and the loading of washcoat, and the reaction conditions, e.g., the space velocity and the oxygen/toluene ratio on the catalytic performance for the combustion of toluene were investigated. It is shown that the Cu‐Mn‐Ag oxides are very active for the combustion of toluene and that the highest catalytic activity is achieved over a monolithic catalyst containing 14.7 wt % of washcoat and 21.2 wt % of active phase with a Ag/Cu/Mn molar ratio of 13.8/43.1/43.1. It is also seen that the optimum catalyst has a good catalytic stability and exhibits an excellent activity not only at a rather high space velocity but also within a wide range of oxygen/toluene ratios.
2,6,8‐Trisubstituted 3‐Hydroxychromone Derivatives as Fluorophores for Live‐Cell Imaging
Authors: Dyrager Christine , Friberg Annika , Dahlén Kristian , Fridén‐Saxin Maria , Börjesson Karl , Wilhelmsson L. Marcus , Smedh Maria , Grøtli Morten , Luthman Kristina
Published: August 2009

We present the synthesis and photophysical characterisation of a series of structurally diverse, fluorescent 2,6,8‐trisubstituted 3‐hydroxychromone derivatives with high fluorescence quantum yields and molar extinction coefficients. Two of these derivatives (9 and 10 a) have been studied as fluorophores for cellular imaging in HeLa cells and show excellent permeability and promising fluorescence properties in a cellular environment. In addition, we have demonstrated by photophysical characterisation of 3‐isobutyroxychromone derivatives that esterification of the 3‐hydroxyl group results in acceptable and useful fluorescence properties.
Alternating Ring‐Opening Metathesis Copolymerization by Grubbs‐Type Initiators with Unsymmetrical N‐Heterocyclic Carbenes

Published: August 2009

A series of RuIV–alkylidenes based on unsymmetrical imidazolin‐2‐ylidenes, that is, [RuCl2{1‐(2,4,6‐trimethylphenyl)‐3‐R‐4,5‐dihydro‐(3H)‐imidazol‐1‐ylidene}(CHPh)(pyridin)] (R=CH2Ph (5), Ph (6), ethyl (7), methyl (8)), have been synthesized. These and the parent initiators [RuCl2(PCy3){1‐(2,4,6‐trimethylphenyl)‐3‐R‐4,5‐dihydro‐(3H)‐imidazol‐1‐ylidene}(CHC6H5)] (R=CH2C6H5 (1), C6H5 (2), ethyl (3)) were used for the alternating copolymerization of norborn‐2‐ene (NBE) with cis‐cyclooctene (COE) and cyclopentene (CPE), respectively. Alternating copolymers, that is, poly(NBE‐alt‐COE)n and poly(NBE‐alt‐CPE)n containing up to 97 and 91 % alternating diads, respectively, were obtained. The copolymerization parameters of the alternating copolymerization of NBE with CPE under the action of initiators 1–3 and 5–8 were determined by using both a zero‐ and first‐order Markov model. Finally, kinetic investigations using initiators 1–3, 6, and 7 were carried out. These revealed that in contrast to the 2nd‐generation Grubbs‐type initiators 1–3 the corresponding pyridine derivatives 6 and 7 represent fast and quantitative initiating systems. Hydrogenation of poly(NBE‐alt‐COE)n yielded a fully saturated, hydrocarbon‐based polymer. Its backbone can formally be derived by 1‐olefin polymerization of CPE (1,3‐insertion) followed by five ethylene units and thus serves as an excellent model compound for 1‐olefin polymerization‐derived copolymers.
The Three‐Component Biginelli Reaction: A Combined Experimental and Theoretical Mechanistic Investigation

Published: August 2009

Biginelli reactions have been monitored by direct infusion electrospray ionization mass spectrometry (ESI‐MS) and key cationic intermediates involved in this three‐component reaction have been intercepted and further characterized by tandem MS experiments (ESI‐MS/MS). Density functional theory calculations were also used to investigate the feasibility of the major competing mechanisms proposed for the Biginelli reaction. The experimental and theoretical results were found to corroborate the iminium mechanism proposed by Folkers and Johnson, whereas no intermediates directly associated with either the more energy demanding Knoevenagel or enamine mechanisms could be intercepted.

Two sample inference in functional linear models
Authors: Horváth Lajos , Kokoszka Piotr , Reimherr Matthew
Published: August 2009

We propose a method of comparing two functional linear models in which explanatory variables are functions (curves) and responses can be either scalars or functions. In such models, the role of parameter vectors (or matrices) is played by integral operators acting on a function space. We test the null hypothesis that these operators are the same in two independent samples. The complexity of the test statistics increases as we move from scalar to functional responses and relax assumptions on the covariance structure of the regressors. They all, however, have an asymptotic chi‐squared distribution with the number of degrees of freedom which depends on a specific setting. The test statistics are readily computable using the R package fda, and have good finite sample properties. The test is applied to egg‐laying curves of Mediterranean flies and to data from terrestrial magnetic observatories. The Canadian Journal of Statistics © 2009 Statistical Society of Canada
Lack of evidence for the μ‐opioid receptor splice variant MOR1C in rats
Authors: Schnell Stephen A. , Wessendorf Martin W.
Published: August 2009

We previously reported the existence of MOR1C mRNA and MOR1C‐immunoreactivity (‐ir) in rats. However, the sequence that we reported for rat MOR1C appears not to be present in the rat genome. We have therefore reexamined whether MOR1C mRNA or MOR1C‐ir exist in rats. We used reverse‐transcription polymerase chain reaction (RT‐PCR) to attempt to amplify MOR1, MOR1A, MOR1B, the rat MOR1C sequence we previously reported, and MOR1C1 and MOR1C2 (which have recently been reported to exist in rats). In RNA extracted from rats, we were able to demonstrate PCR products representing MOR1, MOR1A, and MOR1B splice variants. All three products were confirmed as related to MOR1 by Southern blot. However, we were unable to detect either the MOR1C product reported previously by us or the MOR1C‐like products reported to exist in rats by others. In RNA extracted from mice we were able to detect MOR1, MOR1A, MOR1B, and MOR1D‐like products. To test the specificity of our MOR1C antiserum, we examined MOR1C‐ir in control and knockout mice. MOR1C‐ir had a distribution in control mice similar to that previously reported in rats, including coexisting with vGLUT2. However, although MOR1‐ir was absent in MOR1 knockout mice, the density and distribution of MOR1C‐ir were unchanged, suggesting that the antiserum crossreacts with another molecule in tissue. We find no evidence for MOR1C mRNA in rats. Furthermore, we conclude that MOR1C‐ir represents crossreactivity. J. Comp. Neurol. 517:452–458, 2009. © 2009 Wiley‐Liss, Inc.
Synaptic organization in the adult Drosophila mushroom body calyx

Published: August 2009

Insect mushroom bodies are critical for olfactory associative learning. We have carried out an extensive quantitative description of the synaptic organization of the calyx of adult Drosophila melanogaster, the main olfactory input region of the mushroom body. By using high‐resolution confocal microscopy, electron microscopy‐based three‐dimensional reconstructions, and genetic labeling of the neuronal populations contributing to the calyx, we resolved the precise connections between large cholinergic boutons of antennal lobe projection neurons and the dendrites of Kenyon cells, the mushroom body intrinsic neurons. Throughout the calyx, these elements constitute synaptic complexes called microglomeruli. By single‐cell labeling, we show that each Kenyon cell's claw‐like dendritic specialization is highly enriched in filamentous actin, suggesting that this might be a site of plastic reorganization. In fact, Lim kinase (LimK) overexpression in the Kenyon cells modifies the shape of the microglomeruli. Confocal and electron microscopy indicate that each Kenyon cell claw enwraps a single bouton of a projection neuron. Each bouton is contacted by a number of such claw‐like specializations as well as profiles of γ‐aminobutyric acid‐positive neurons. The dendrites of distinct populations of Kenyon cells involved in different types of memory are partially segregated within the calyx and contribute to different subsets of microglomeruli. Our analysis suggests, though, that projection neuron boutons can contact more than one type of Kenyon cell. These findings represent an important basis for the functional analysis of the olfactory pathway, including the formation of associative olfactory memories. J. Comp.

Supramolecular Assembly of a 2D Binary Network of Pentacene and Phthalocyanine on Cu(100)
Authors: Krauss Tobias N. , Barrena Esther , Dosch Helmut , Wakayama Yutaka
Published: August 2009

A crystalline nanoporous molecular network was tailored by supramolecular assembly of pentacene and F16CuPc on Cu(100). The structure and self‐assembly mechanisms of the pure and binary layers were analyzed by STM. F16CuPc films and mixed layers of pentacene/F16CuPc in a ratio of 2:1 show two enantiomorphic chiral domains with high structural order in contrast to pentacene which exhibits no long‐range order in pure films. A model of the epitaxial relationship on Cu(100) is given, which suggests CF⋅⋅⋅H bonding as a possible driving force for the bimolecular self‐assembly in addition to the still strong interaction between the substrate and the organic bilayer.
Obesity predisposes to Th17 bias

Published: August 2009

Obesity is associated with numerous inflammatory conditions including atherosclerosis, autoimmune disease and cancer. Although the precise mechanisms are unknown, obesity‐associated rises in TNF‐α, IL‐6 and TGF‐β are believed to contribute. Here we demonstrate that obesity selectively promotes an expansion of the Th17 T‐cell sublineage, a subset with prominent pro‐inflammatory roles. T‐cells from diet‐induced obese mice expand Th17 cell pools and produce progressively more IL‐17 than lean littermates in an IL‐6‐dependent process. The increased Th17 bias was associated with more pronounced autoimmune disease as confirmed in two disease models, EAE and trinitrobenzene sulfonic acid colitis. In both, diet‐induced obese mice developed more severe early disease and histopathology with increased IL‐17+ T‐cell pools in target tissues. The well‐described association of obesity with inflammatory and autoimmune disease is mechanistically linked to a Th17 bias.
A possible contribution of retinoids to regulation of fetal B lymphopoiesis
Authors: Chen Xinrong , Welner Robert S. , Kincade Paul W.
Published: August 2009

We recently found that all trans retinoic acid (ATRA) accelerated B lymphocyte formation. In the current study, we address the question whether retinoids account for the rapid lymphopoiesis that is characteristic of fetal progenitors. Surprisingly, addition of ATRA to fetal liver cultures actually reduced B lymphopoiesis. A pan‐retinoid receptor antagonist selectively suppressed lymphocyte formation from fetal and adult progenitors, suggesting some normal contribution of retinoids to this process. Consistent with this role, B lymphopoiesis was compromised in the marrow of mice with prolonged vitamin A deficiency. Recently identified B1 progenitors from adult marrow were similar to adult B2 progenitors in that their differentiation was stimulated by ATRA. The inhibitory response observed with fetal cells was seen when adult progenitors were exposed to high doses in culture or when adult mice were treated with ATRA for 2 wk. In addition to explosive lymphocyte generation, fetal progenitors tend to be less IL‐7 dependent than their adult counterparts, but ATRA did not make fetal progenitors IL‐7 independent. We conclude that all known categories of B lineage progenitors are responsive to retinoids and probably regulated by these compounds under physiological conditions. Retinoids may account in part for rapid differentiation in fetal life, but not all unique features of fetal progenitors.
Dynamics of peripheral tolerance and immune regulation mediated by Treg
Authors: Sakaguchi Shimon , Wing Kajsa , Yamaguchi Tomoyuki
Published: August 2009

Peripheral self‐tolerance and immune homeostasis are maintained, at least in part, by the balance between Treg and effector T cells. Naturally, arising CD25+CD4+ Treg, which express the transcription factor Foxp3, suppress the activation and proliferation of other lymphocytes in multiple ways. A CTLA‐4‐dependent suppressive mechanism is shared by every Foxp3+ Treg at any location and its disruption breaches self‐tolerance and immune homeostasis, suggesting that it is a core mechanism of suppression. Depending on the environment, Foxp3+ Treg also differentiate to exhibit additional suppressive mechanisms, including the secretion of immunosuppressive cytokines. Naïve T cells acquire Foxp3 expression and suppressive activity under certain in vivo and in vitro conditions, whereas some Foxp3+ T cells may lose Foxp3 and suppressive activity following proliferation in an IL‐2‐deficient environment. Moreover, activated effector T cells frequently secrete suppressive cytokines, such as IL‐10, in a negative feedback fashion. These findings, when taken together, indicate that peripheral immune tolerance and homeostasis are dynamically maintained by functional differentiation within the Foxp3+ population, occasional conversion between Treg and non‐Treg cells, and the interactions among them. These dynamics provide ample opportunities for immune intervention for the benefit of the host.
Improvement of Staphylococcus xylosus lipase production through optimization of the culture conditions
Authors: Ghribi Dhouha , Sayari Adel , Gargouri Youssef , Bezzine Sofiane
Published: August 2009

The Staphylococcus xylosus strain produces without induction an original lipase named S. xylosus lipase (SXL). Since considerable interest has been given to microbial lipases for biotechnology applications like detergents, food, drugs and pharmaceutical products, improvement of their production is of great importance to reduce the final cost. This goal could be reached through the optimization of several physicochemical culture conditions. Indeed, an appropriate medium was formulated for SXL production. It was composed of 17 g/L pancreatic digest of casein, 2.5 g/L glucose, 6 g/L yeast extract, 0.75 g/L ammonium sulfate corresponding to a C/N ratio of 6, 1 g/L K2HPO4 and 1 g/L KH2PO4. In such a medium, SXL production reached 42 U/mL. Moreover, the usefulness of such a medium for large‐scale production of SXL was also evidenced in an automated fully controlled 2.6‐L fermenter. It was shown that aeration of the medium, which strongly affected the growth, regulated the lipase synthesis by the produced cells. It was found that when using a dissolved oxygen saturation of the medium of 50%, the SXL production reached 62 U/mL.
Convergent Synthesis of Pancratistatin from Piperonal and Xylose
Authors: Dam Johan Hygum , Madsen Robert
Published: August 2009

A synthesis of the antitumour agent pancratistatin is described from piperonal and D‐xylose. Piperonal is converted into cinnamyl bromide 11 while methyl 5‐iodoribofuranoside 12 is derived from xylose. The allylic bromide and the iodocarbohydrate are combined in a zinc‐mediated tandem reaction to afford a highly functionalised 1,7‐diene, which is then converted into the corresponding cyclohexene by ring‐closing olefin metathesis. Subsequent Overman rearrangement, dihydroxylation and deprotection afford the natural product in a total of 25 steps from the two starting materials. The longest linear sequence is from piperonal and gives rise to pancratistatin in 18 steps and 7.0 % overall yield. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
On‐line solid phase extraction CZE for the simultaneous determination of lanthanum and gadolinium at picogram per liter levels
Authors: Vizioli Nora , Gil Raúl , Martínez Luis Dante , Fernanda Silva María
Published: August 2009

A non‐specific on‐line method is presented for the extraction and preconcentration of two rare earth elements using a microcartridge containing C18‐derivatized silica particles prior to their analysis by CZE. The microcartridge, named analyte concentrator, was coupled on‐line to the inlet of the separation capillary (fused‐silica (FS) capillary, 75 μm id ×12 cm from the inlet to the microcartidge and 37 cm from the microcartridge to the detector). The reversed‐phase sorbent quantitatively retained gadolinium (Gd) and lanthanum (La) as 2‐(5‐bromo‐2‐pyridylazo)‐5‐diethylaminophenol complexes in the presence of non‐ionic micelles of polyethylene glycol tert‐octylphenyl ether, enabling sample clean‐up and concentration enhancement with minimum sample handling. The rare earth elements chelates were released from the sorbent with methanol and then analyzed by CZE with diode array detection. A background electrolyte of 20 mM sodium tetraborate containing 8% ACN, pH 9.0, was found to be optimal for the separation of metal chelates. The concentration limits of detection were lowered to picogram per liter levels (20 pg/L for La and 80 pg/L for Gd). A 1000‐fold improvement in concentration sensitivity for La‐ and Gd‐2‐(5‐bromo‐2‐pyridylazo)‐5‐diethylaminophenol complexes with respect to CZE without preconcentration was reached.
