The association of unresolved attachment status and cognitive processes in maltreated adolescents
Authors: Webster Linda , Hackett Rachelle Kisst , Joubert David 
Published: January 2009

AbstractThis exploratory investigation sought to gain a better understanding of the mental representations of attachment in maltreated adolescents, and how, if at all, unresolved attachment representations are related to cognitive processes in this population. Measures of cognitive functioning, attachment state of mind and parent ratings on attention were obtained from 38 adolescents with a history of maltreatment. Results showed that maltreated adolescents with unresolved states of mind in regard to attachment scored significantly lower on measures of cognitive processes of attention, working memory and cognitive efficiency, even when intelligence was controlled for in the analyses. Theoretical considerations, implications for future research and clinical implications are discussed. Copyright © 2009 John Wiley & Sons, Ltd.
‘Alcohol is my friend’: Young middle class women discuss their relationship with alcohol
Authors: Rúdólfsdóttir Annadís G. , Morgan Philippa 
Published: January 2009

AbstractIn recent years concerns have been raised about the increase in alcohol consumption amongst young women in the UK. This paper presents a qualitative study of the experiences and relationship young, middle‐class, female students have with alcohol. Interviews with five friendship groups were analysed using thematic analysis. The findings reveal the integral part alcohol plays in the young women's social lives and its importance in the staging of the young female self. Drinking can be seen as empowering and confidence boosting. However, the ‘friendship’ between femininity and alcohol is a contemptuous and fragile one. Loosing public self‐control is seen as an invitation to unwanted sexual attention and even exploitation. The interviews not only illustrate the gendered and classed behavioural codes imposed on women, but also how the women have made these their own. We discuss how the young women's description of ‘problem drinking’ as being, for the most part, the preserve of men and so called ‘chavvies’, allows them to project an image of themselves as feminine and in control of their own drinking. We conclude that this could have implications for the extent to which they see the messages of public health campaigns about the dangers of ‘binge’ drinking as relating to them.

Published: January 2009

AbstractWe have developed a method for the photomanipulation of lipid membrane morphology in which the shape of a vesicle can be switched by light through the use of a synthetic photosensitive amphiphile containing an azobenzene unit (KAON12). We prepared cell‐sized liposomes from KAON12 and 1,2‐dioleoyl‐sn‐glycero‐3‐phosphocholine (DOPC) and conducted real‐time observations of vesicular transformation in the photosensitive liposome by phase‐contrast microscopy. Budding transitions—either budding toward the centre of the liposome (endo‐bud) or budding out of the liposome (exo‐bud)—could be controlled by light. We discuss the mechanism of this transformation in terms of the change in the effective membrane surface area due to photoisomerization of the constituent molecules.

Published: January 2009

AbstractObjective:To evaluate the feasibility of a new 0.014″ CiTop™ guidewire to cross total occlusions within normal and diseased blood vessels; proof of concept. Background: Despite recent advances, chronic arterial occlusions remain the main obstacle of coronary and peripheral interventions. Methods: The OVALUM CiTop™ 0.014″ guidewire is an over‐the‐wire catheter designed to penetrate through chronic total occlusions (CTO) and allow for further PCI interventions. The CiTop™ guidewire was tested in normal peripheral and coronary arteries of swine (n = 7) and in totally occluded arterial lesions within human amputations (n = 10).Results:The CiTop™ 0.014″ guidewire was operated successfully in seven peripheral blood vessels and 12 coronary arteries without angiographic or histological evidence of damage to the arterial wall. The CiTop™ crossed 9 of the 10 occluded segments within the human amputation with no angiographic or histological evidence of arterial damage (90% success rate). Average time to cross the occlusion was 4.6 ± 5.6 min. In one artery (10%), angiographic evidence of perforation was noted and there was histological evidence for arterial wall damage.Conclusion:Our data show that the new 0.014″ CiTop™ guidewire can be well operated within normal peripheral and coronary arteries of swine, and with minimal complications within totally occluded blood vessels from human amputations while effectively penetrating and crossing total arterial occlusions. © 2009 Wiley‐Liss, Inc.
Prevention of thrombus embolization during primary percutaneous intervention using a novel mesh covered stent
Authors: Jain Ajay , Weerackody Roshan , Kennon Simon , Rothman Martin 
Published: January 2009

AbstractEmbolization of athero‐thrombotic material during primary percutaneous coronary intervention is a common cause of periprocedural complication. Methods developed to reduce embolization include thrombus aspiration, and distal protection. We report five cases of primary percutaneous intervention to coronary arteries that contain large amounts of thrombus, using a novel mesh covered stent. The mesh covering of the stent is designed such that it is theoretically able to ensnare thrombus and thus prevent distal migration of embolic material. In all cases, TIMI grade III flow was achieved at the end of the procedure, despite the extensive thrombus burden. © 2009 Wiley‐Liss, Inc.
Is the left atrial appendage more than a simple appendage?

Published: January 2009

AbstractThe left atrial appendage (LAA) is a cardiac structure with unique anatomic and functional features. It is significantly more than a simple chamber appended to the left atrium (LA), differing from the LA in structure, function, and hormonal activity. Unfortunately, it is the source of more than 90% of cardiac‐based emboli, particularly in atrial fibrillation, mandating lifelong anticoagulation. Percutaneous LAA exclusion was developed to limit or eliminate cardioembolic events in patients with atrial fibrillation. Benign healing of the appendage occurs without adverse hemodynamic effects, and with no residual surface thrombus or tissue damage. The feasibility of this treatment is now established, suggesting that percutaneous therapy is safe, practical and possibly effective to eliminate the need for anticoagulation and significantly reduce cardioembolic events. © 2009 Wiley‐Liss, Inc.
Morphological Transformation of Co(OH)2 Microspheres from Solid to Flowerlike Hollow Core–Shell Structures

Published: January 2009

AbstractCo(OH)2 that blooms: Flowerlike hollow spherical architectures of cobalt hydroxide obtained through a facile solvothermal process are reported for the first time (see picture). Their growth process involves aggregation of cobalt hydroxide nanoparticles into solid spheres and a hollowing effect through subsequent dissolution‐diffusion‐redeposition of the smaller crystallites under the surface layer.magnified imageWe report, for the first time, a detailed investigation into the formation of highly uniform, 3D, flowerlike, hollow, spherical architectures of cobalt hydroxide through a facile solvothermal process. Various controlling parameters were examined, such as water content in starting materials, reaction time, cobalt(II) precursor concentration, and reaction temperature. On the basis of the experimental results, the formation mechanism of these flowerlike cobalt hydroxide hollow spheres involves aggregation of cobalt hydroxide building clusters into solid spheres and hollowing effect through subsequent dissolution, diffusion, and re‐deposition of the smaller crystallites under the surface layer driven by an Ostwald ripening process. Metallic cobalt hollow spheres have also been obtained by thermal decomposition of cobalt hydroxide flowers in a mixed gas of Ar+4 % H2 at 400 °C. The morphology and composition of the products were characterized by X‐ray diffraction, field‐emission scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, and (high resolution) transmission electron microscopy.
Oxidation of Ethers, Alcohols, and Unfunctionalized Hydrocarbons by the Methyltrioxorhenium/H2O2 System: A Computational Study on Catalytic CH Bond Activation
Authors: Karlsson Erik A. , Privalov Timofei 
Published: January 2009

AbstractA concerted mechanism that does not involve an ionic intermediate was revealed by a DFT study on oxidation of ethers, alcohols, and unfunctionalized hydrocarbons by methyltrioxorhenium/H2O2. Instead, CH insertion occurs through hydride transfer and then turns into a hydroxide transfer/rebound in a concerted fashion. The picture shows selected frames from an intrinsic reaction coordinate scan from the transition state to the product for the oxidation of cis‐1,2‐dimethylcyclohexane.magnified imageThe potential‐energy surfaces (PESs) of methyltrioxorhenium (MTO)‐catalyzed CH insertion reactions in the presence of hydrogen peroxide were studied by accurate DFT methods for a series of substrates including unsaturated hydrocarbons, an ether, and an alcohol. Based on the comprehensive analysis of transition states and intrinsic reaction coordinate (IRC) scans, CH insertion was found to proceed by a concerted mechanism that does not require, as previously thought, a side‐on or a butterfly‐like transition state. We found that a typical transition state follows requirements of the SN2 reaction instead. Furthermore, by exploring the PESs of several CH insertion reactions, we discovered that no ionic intermediate is formed even in a polar solvent. The latter was modeled within the self‐consistent reaction field approach in a polarizable continuum model (PB‐SCRF/PCM). According to our study, CH insertion occurs by a concerted but highly asynchronous mechanism that first proceeds by hydride transfer and then turns into hydroxide transfer/rebound. For the oxidation of alcohols, CH bond cleavage occurs without formation of alkoxide intermediates on the dominant pathway. The computed deuterium kinetic isotope effect of 2.9 for the hydride‐transfer transition state for alcohol oxidation is in good agreement with the experimental kH/kD ration of 3.2 reported by Zauche and Espenson. As confirmed by IRC and PES scans in different solvents, the OH‐rebound phase of the CH insertion pathway demonstrates strong similarities with the rebound mechanism that was previously proposed for cytochrome P450 and metalloporphyrin‐catalyzed oxidations.
Matrix Isolation and Spectroscopic Characterization of the Phenylperoxy Radical and Its Rearranged Products
Authors: Mardyukov Artur , Sander Wolfram 
Published: January 2009

AbstractThe phenylperoxy radical1has been synthesized by the reaction of the phenyl radical2with3O2. Radical1could be either generated in the gas phase and subsequently trapped in solid argon at 10 K, or directly synthesized in argon matrices. By reacting2as well as its perdeuterated isotopomer [D5]‐2with16O2and with18O2, respectively, the four isotopomers [H5]‐16O2‐1, [D5]‐16O2‐1, [H5]‐18O2‐1, and [D5]‐18O2‐1were matrix‐isolated and characterized by IR spectroscopy. The experimental IR spectra are in excellent agreement with results from DFT calculations. Irradiation of1with visible light produces the 2‐oxepinoxy radical5in a clean reaction. Subsequent irradiation results in ring‐opening and formation of several conformers of ketoketene6. The radicals1,5, and6play an important role in the combustion of aromatic hydrocarbons and could now be isolated and spectroscopically characterized for the first time.
Applications of Multicomponent Reactions to the Synthesis of Diverse Heterocyclic Scaffolds
Authors: Sunderhaus James D. , Martin Stephen F. 
Published: January 2009

AbstractThe sequencing of multicomponent reactions (MCRs) and subsequent cyclization reactions is a powerful stratagem for the rapid synthesis of diverse heterocyclic scaffolds. The optimal MCR is sufficiently flexible that it can be employed to generate adducts bearing a variety of functional groups that may then be selectively paired to enable different cyclization manifolds, thereby leading to a diverse collection of products. The growing interest in diversity‐oriented synthesis has led to increased attention to this paradigm for library synthesis, which has inspired many advances in the design and implementation of MCRs for the construction of diverse heterocyclic scaffolds.

AbstractThe first highly enantioselective allylic–allylic alkylation of α,α‐dicyanoalkenes and Morita–Baylis–Hillman carbonates by dual catalysis of (DHQD)2AQN and (S)‐BINOL has been investigated. Excellent stereoselectivities have been achieved for a broad spectrum of substrates (d.r. > 99:1, up to 99 % ee). The multifunctional allylic products could be efficiently converted to a range of complex chiral cyclic frameworks.
