Published: July 2014

Research in Australia has examined factors associated with filicide in order to more accurately instigate points of intervention. Factors include parental separation/divorce, depression in the perpetrator and domestic violence. Therefore, services that facilitate men's behaviour change programmes provide one such point of intervention. Relationships Australia NSW offers ‘Taking Responsibility’: an 18‐week programme that addresses men's use of violence and abuse in their intimate relationships, through group work and individual support. Fundamental to this programme is the whole family's safety, which is managed through initial screening, ongoing contact and access to additional therapeutic services. Programme evaluation has revealed that men's change factors are influenced by varying levels of motivation, at intake and throughout. These accounts have indicated that the relationship status with their partner affects their motivation, which in turn has the potential to affect their investment in the programme. This relates to both increased and diminished motivation. Partners and former partners, however, expressed ambivalence towards their continuing relationships. Given the risk factors for filicide associated with domestic violence and separation, these interviews contribute to what is known about men's motivation to change violent and abusive behaviours, and in turn the clinical objectives for professionals working on these programmes. Copyright © 2014 John Wiley & Sons, Ltd.‘Fundamental to this programme is the whole family's safety’Key Practitioner Messages:

The client's relationship status often changes throughout the course of a men's behaviour change programme.
A separation can negatively affect motivation and behaviour change processes.
Professionals working with men who use violence are advised to raise the topic of the client's relationship status, to prevent attrition, and work with them to broaden their motivations.

ObjectivesWe investigated the temporal patterns of drug‐eluting stents (DES) failure and its relationship with clinical outcomes in patients with DES failure.BackgroundTime to DES failure is widely variable, but little information is available on the temporal patterns of DES failure and its impact on clinical outcomes.MethodsThe angiographic patterns of DES failure and clinical outcomes in 633 patients with 676 lesions who presented with their first instance of DES failure were analyzed. The primary outcome was all‐cause death following treatment for DES failure.ResultsDES failure occurred in a median of 10.1 months after the index procedure. We identified 548 and 85 instances of DES restenosis (86.6%) and stent thrombosis (13.4%), respectively. Patients were divided into three groups according to the interval from the index procedure to DES failure: group 1 (early DES failure: <12 months), group 2 (late: 12–36 months), and group 3 (very late: ≥36 months). Acute myocardial infarction was more common in patients who developed failure after ≥12 months than patients with earlier presentations. Focal DES failure was more common in group 1, whereas nonfocal DES failure in groups 2 and 3. During follow‐up after retreatment (median, 52.8 months), all‐cause death was significantly higher in group 3 compared with group 1 (adjusted hazard ratio, 2.97; 95%CI, 1.31–6.74; P = 0.009). Similar findings were observed in terms of the rates of death or myocardial infarction.ConclusionsLate DES failure is more likely to progress to acute myocardial infarction, aggressive angiographic patterns, and worse outcomes following retreatment. © 2014 Wiley Periodicals, Inc.

AbstractSeveral, partly new, ionic liquids (ILs) containing imidazolium and ammonium cations as well as the medium‐sized [NTf2]− (0.230 nm3; Tf=CF3SO3−) and the large [Al(hfip)4]− (0.581 nm3; hfip=OC(H)(CF3)2) anions were synthesized and characterized. Their temperature‐dependent viscosities and conductivities between 25 and 80 °C showed typical Vogel–Fulcher–Tammann (VFT) behavior. Ion‐specific self‐diffusion constants were measured at room temperature by pulsed‐gradient stimulated‐echo (PGSTE) NMR experiments. In general, self‐diffusion constants of both cations and anions in [Al(hfip)4]−‐based ILs were higher than in [NTf2]−‐based ILs. Ionicities were calculated from self‐diffusion constants and measured bulk conductivities, and showed that [Al(hfip)4]−‐based ILs yield higher ionicities than their [NTf2]− analogues, the former of which reach values of virtually 100 % in some cases.From these observations it was concluded that [Al(hfip)4]−‐based ILs come close to systems without any interactions, and this hypothesis is underlined with a Hirshfeld analysis. Additionally, a robust, modified Marcus theory quantitatively accounted for the differences between the two anions and yielded a minimum of the activation energy for ion movement at an anion diameter of slightly greater than 1 nm, which fits almost perfectly the size of [Al(hfip)4]−. Shallow Coulomb potential wells are responsible for the high mobility of ILs with such anions.
A Substrate‐Based Approach to Skeletal Diversity from Dicobalt Hexacarbonyl (C1)‐Alkynyl Glycals by Exploiting Its Combined Ferrier–Nicholas Reactivity
Authors: Lobo Fernando , Gómez Ana M. , Miranda Silvia , López J. Cristóbal 
Published: July 2014

AbstractNovel substrates that combine dicobalt hexacarbonyl propargyl (Nicholas) and pyranose‐derived allylic (Ferrier) cations have been generated by treatment of hexacarbonyldicobalt (C‐1)‐alkynyl glycals with BF3.Et2O. The study of these cations has resulted in the discovery of novel reaction pathways that have shown to be associated to the nature of O‐6 substituent in the starting alkynyl glycals. Accordingly, compounds resulting from ring expansion (oxepanes), ring contraction (tetrahydrofurans), or branched pyranoses, by incorporation of nucleophiles, can be obtained from 6‐O‐benzyl, 6‐hydroxy, or 6‐O‐silyl derivatives, respectively. The use of a 6‐O‐allyl alkynyl glycal led to a suitable funtionalized oxepane able to experience an intramolecular Pauson–Khand cyclization leading to a single tricyclic derivative.

AbstractProtoporphyrin IX‐zinc oxide (PP‐ZnO) nanohybrids have been synthesized for applications in photocatalytic devices. High‐resolution transmission electron microscopy (HRTEM), X‐ray diffraction (XRD), and steady‐state infrared, absorption, and emission spectroscopies have been used to analyze the structural details and optical properties of these nanohybrids. Time‐resolved fluorescence and transient absorption techniques have been applied to study the ultrafast dynamic events that are key to photocatalytic activities. The photocatalytic efficiency under visible‐light irradiation in the presence of naturally abundant iron(III) and copper(II) ions has been found to be significantly retarded in the former case, but enhanced in the latter case. More importantly, femtosecond (fs) transient absorption data have clearly demonstrated that the residence of photoexcited electrons from the sensitizer PP in the centrally located iron moiety hinders ground‐state bleach recovery of the sensitizer, affecting the overall photocatalytic rate of the nanohybrid. The presence of copper(II) ions, on the other hand, offers additional stability against photobleaching and eventually enhances the efficiency of photocatalysis. In addition, we have also explored the role of UV light in the efficiency of photocatalysis and have rationalized our observations from femtosecond‐ to picosecond‐resolved studies.
Carboxylate Switch between Hydro‐ and Carbopalladation Pathways in Regiodivergent Dimerization of Alkynes

Published: July 2014

AbstractExperimental and theoretical investigation of the regiodivergent palladium‐catalyzed dimerization of terminal alkynes is presented. Employment of N‐heterocyclic carbene‐based palladium catalyst in the presence of phosphine ligand allows for highly regio‐ and stereoselective head‐to‐head dimerization reaction. Alternatively, addition of carboxylate anion to the reaction mixture triggers selective head‐to‐tail coupling. Computational studies suggest that reaction proceeds via the hydropalladation pathway favoring head‐to‐head dimerization under neutral reaction conditions. The origin of the regioselectivity switch can be explained by the dual role of carboxylate anion. Thus, the removal of hydrogen atom by the carboxylate directs reaction from the hydropalladation to the carbopalladation pathway. Additionally, in the presence of the carboxylate anion intermediate, palladium complexes involved in the head‐to‐tail dimerization display higher stability compared to their analogues for the head‐to‐head reaction.

AbstractA series of functionalized dialkenylsilsesquioxanes were obtained by efficient and highly stereoselective silylative coupling and cross‐metathesis of divinylsubstituted double‐decker silsesquioxanes (DDSQ‐2SiVi) with substituted styrenes and other olefins. Both reactions proceed highly stereoselectively and lead to nearly quantitative formation of E isomers. The optimized reaction conditions for styrene were adopted for successful silylative coupling polycondensation of DDSQ‐2SiVi with 1,4‐divinylbenzene yielding stereoregular cooligomer containing double‐decker (silsesquioxyl‐silylene)‐vinylene‐phenylene units.

Brain‐derived neurotrophic factor but not vesicular zinc promotes TrkB activation within mossy fibers of mouse hippocampus in vivo
Authors: Helgager Jeffrey , Huang Yang Zhong , Mcnamara James O. 
Published: July 2014

ABSTRACTThe neurotrophin receptor, TrkB receptor tyrosine kinase, is critical to central nervous system (CNS) function in health and disease. Elucidating the ligands mediating TrkB activation in vivo will provide insights into its diverse roles in the CNS. The canonical ligand for TrkB is brain‐derived neurotrophic factor (BDNF). A diversity of stimuli also can activate TrkB in the absence of BDNF, a mechanism termed transactivation. Zinc, a divalent cation packaged in synaptic vesicles along with glutamate in axons of mammalian cortical neurons, can transactivate TrkB in neurons and heterologous cells in vitro. Yet the contributions of BDNF and zinc to TrkB activation in vivo are unknown. To address these questions, we conducted immunohistochemical (IHC) studies of the hippocampal mossy fiber axons and boutons using an antibody selective for pY816 of TrkB, a surrogate measure of TrkB activation. We found that conditional deletion of BDNF resulted in a reduction of pY816 in axons and synaptic boutons of hippocampal mossy fibers, thereby implicating BDNF in activation of TrkB in vivo. Unexpectedly, pY816 immunoreactivity was increased in axons but not synaptic boutons of mossy fibers in ZnT3 knockout mice that lack vesicular zinc. Marked increases of BDNF content were evident within the hippocampus of ZnT3 knockout mice and genetic elimination of BDNF reduced pY816 immunoreactivity in these mice, implicating BDNF in enhanced TrkB activation mediated by vesicular zinc depletion. These findings support the conclusion that BDNF but not vesicular zinc activates TrkB in hippocampal mossy fiber axons under physiological conditions. J. Comp.

Characterization of axons expressing the artemin receptor in the female rat urinary bladder: A comparison with other major neuronal populations
Authors: Forrest Shelley L. , Osborne Peregrine B. , Keast Janet R. 
Published: July 2014

ABSTRACTArtemin is a member of the glial cell line‐derived neurotrophic factor (GDNF) family that has been strongly implicated in development and regeneration of autonomic nerves and modulation of nociception. Whereas other members of this family (GDNF and neurturin) primarily target parasympathetic and nonpeptidergic sensory neurons, the artemin receptor (GFRα3) is expressed by sympathetic and peptidergic sensory neurons that are also the primary sites of action of nerve growth factor, a powerful modulator of bladder nerves. Many bladder sensory neurons express GFRα3 but it is not known if they represent a specific functional subclass. Therefore, our initial aim was to map the distribution of GFRα3‐immunoreactive (‐IR) axons in the female rat bladder, using cryostat sections and whole wall thickness preparations. We found that GFRα3‐IR axons innervated the detrusor, vasculature, and urothelium, but only part of this innervation was sensory. Many noradrenergic sympathetic axons innervating the vasculature were GFRα3‐IR, but the noradrenergic innervation of the detrusor was GFRα3‐negative. We also identified a prominent source of nonneuronal GFRα3‐IR that is likely to be glial. Further characterization of bladder nerves revealed specific structural features of chemically distinct classes of axon terminals, and a major autonomic source of axons labeled with neurofilament‐200, which is commonly used to identify myelinated sensory axons within organs. Intramural neurons were also characterized and quantified. Together, these studies reveal a diverse range of potential targets by which artemin could influence bladder function, nerve regeneration, and pain, and provide a strong microanatomical framework for understanding bladder physiology and pathophysiology.

Retinal projection to the pretectal nucleus lentiformis mesencephali in pigeons (Columba livia)

Published: July 2014

ABSTRACTIn birds, the nucleus of the basal optic root (nBOR) and the nucleus lentiformis mesencephali (LM) are retinal‐recipient nuclei involved in the analysis of optic flow and the generation of the optokinetic response. The nBOR receives retinal input from displaced ganglion cells (DGCs), which are found at the margin of the inner nuclear and inner plexiform layers, rather than the ganglion cell layer. The LM receives afferents from retinal ganglion cells, but whether DGCs also project to LM remains unclear. To resolve this issue, we made small injections of retrograde tracer into LM and examined horizontal sections through the retina. For comparison, we also had cases with injections in nBOR, the optic tectum, and the anterior dorsolateral thalamus (the equivalent to the mammalian lateral geniculate nucleus). From all LM injections both retinal ganglion cells and DGCs were labeled. The percentage of DGCs, as a proportion of all labeled cells, varied from 2–28%, and these were not different in morphology or size compared to those labeled from nBOR, in which the proportion of DGCs was much higher (84–93%). DGCs were also labeled after injections into the anterior dorsolateral thalamus. The proportion was small (2–3%), and these DGCs were smaller in size than those projecting to the nBOR and LM. No DGCs were labeled from an injection in the optic tectum. Based on an analysis of size, we suggest that different populations of retinal ganglion cells are involved in the projections to LM, nBOR, the optic tectum, and the anterior dorsolateral thalamus. J.

Do Ni/Cu and Cu/Ni Alloys have Different Catalytic Performances towards Water‐Gas Shift? A Density Functional Theory Investigation
Authors: Huang Yu Cheng , Zhou Tao , Liu Hai , Ling ChongYi , Wang SuFan , Du Jin Yan 
Published: July 2014

AbstractDensity functional calculations were preformed to investigate whether adding Ni into a Cu surface (denoted as Cu/Ni) or adding Cu into a Ni surface (Ni/Cu) is more efficient for catalyzing the water‐gas shift (WGS)? The reactions of water dissociation and monoxide dissociation were selected to assess the activity and selectivity towards WGS, respectively. Our results show that Ni‐atom modification of surfaces is thermodynamically favorable for both reactions. Kinetically, compared with pure Cu, water dissociation is greatly facilitated on Ni‐modified surfaces, and the activity is insensitive to the Ni concentration; however, monoxide dissociation is not well‐promoted on one Ni‐atom‐modified surfaces, but two Ni‐atom modification can notably decrease the dissociation barriers. Overall, on the basis of these results, we conclude that 1) the catalytic performance of bimetallic metals is superior to monometallic ones; 2) at the same Ni concentration on the surface, Cu/Ni and Ni/Cu alloys have almost the same performance towards WGS; and 3) to acquire high WGS performance, the surface Ni atoms should either be low in concentration or highly dispersed.
Life‐history traits predict perennial species response to fire in a desert ecosystem

Published: July 2014

AbstractThe Mojave Desert of North America has become fire‐prone in recent decades due to invasive annual grasses that fuel wildfires following years of high rainfall. Perennial species are poorly adapted to fire in this system, and post‐fire shifts in species composition have been substantial but variable across community types. To generalize across a range of conditions, we investigated whether simple life‐history traits could predict how species responded to fire. Further, we classified species into plant functional types (PFTs) based on combinations of life‐history traits and evaluated whether these groups exhibited a consistent fire‐response. Six life‐history traits varied significantly between burned and unburned areas in short (up to 4 years) or long‐term (up to 52 years) post‐fire datasets, including growth form, lifespan, seed size, seed dispersal, height, and leaf longevity. Forbs and grasses consistently increased in abundance after fire, while cacti were reduced and woody species exhibited a variable response. Woody species were classified into three PFTs based on combinations of life‐history traits. Species in Group 1 increased in abundance after fire and were characterized by short lifespans, small, wind‐dispersed seeds, low height, and deciduous leaves. Species in Group 2 were reduced by fire and distinguished from Group 1 by longer lifespans and evergreen leaves. Group 3 species, which also decreased after fire, were characterized by long lifespans, large non‐wind dispersed seeds, and taller heights. Our results show that PFTs based on life‐history traits can reliably predict the responses of most species to fire in the Mojave Desert. Dominant, long‐lived species of this region possess a combination of traits limiting their ability to recover, presenting a clear example of how a novel disturbance regime may shift selective environmental pressures to favor alternative life‐history strategies.

AbstractThe reaction of Salen‐like ZnII and NiII precursors with carbacylamidophosphate lanthanide moieties yields six new types of 3d–4f compounds. The complexes were characterized by means of 1H, 31P NMR and IR spectroscopy, elemental analysis, ESI mass spectrometry, and X‐ray diffraction analysis. Depending on the Schiff base ligands, the NiII ion adopts either a square‐planar or an octahedral geometry, whereas the ZnII ion has a tetragonal‐pyramidal geometry. The coordination number of lanthanides is nine or ten. Hydrolytic activities of some heterobimetallic Zn–Ln and Ni–Ln coordination compounds in the reaction of intramolecular hydrolytic degradation of the 2‐(hydroxypropyl)‐p‐nitrophenyl phosphate were investigated.
Synthesis of Allylic and Propargylic Trifluoromethyl Thioethers by Copper(I)‐Catalyzed Trifluoromethylthiolation of Allylic Bromides and Propargylic Chlorides

Published: July 2014

AbstractAn efficient method is reported for the copper(I)‐catalyzed trifluoromethylthiolation of allylic bromides by using elemental sulfur and CF3SiMe3. This rate of this transformation was significantly accelerated in the presence of 18‐crown‐6, and the reaction afforded the desired products in moderate to excellent yields with high stereo‐ and regioselectivity. This method can tolerate a number of functional groups and provides facile access to a variety of allylic trifluoromethyl thioethers. The copper(I)‐catalyzed trifluoromethylthiolation of propargylic chlorides was also investigated. A plausible mechanism that involves an allylcopper(III) intermediate is proposed.

Published: July 2014

In this study, a Whelk‐O1 chiral stationary phase immobilized on 2.5 μm silica particles was employed in nanoLC. Two nanocolumns (180 and 250 mm long, 75 μm id) with a single polymeric organic monolithic outlet frit were packed under high‐pressure ultrasonic‐assisted packing procedure. The monolithic outlet frit was prepared by thermal polymerization of methacrylate‐based monomers affording high‐mechanical stability and high‐pressure resistance. Very efficient enantioseparations with more than 70 000 plates/m were achieved in normal phase mode by eluting (+/−) acenaphthenol. Nanocolumns were also tested in RP mode by using on‐line MS detection with nano‐spray ESI ion source. Kinetic performances of columns in RP mode were comparable to those in normal phase‐conditions.
