Published: March 2019

AbstractBackgroundSeveral variables have been evidenced for their association with violent reoffending. Resultant interventions have been suggested, yet the rate of recidivism remains high. Alexithymia, characterised by deficits in emotion processing and verbal expression, might interact with these other risk factors to affect outcomes.AimOur goal was to examine the role of alexithymia as a possible moderator of risk factors for violent offender recidivism. Our hypothesis was that, albeit with other risk factors, alexithymia increases the risk of violent reoffending.MethodWe conducted a systematic literature review, using terms for alexithymia and violent offending and their intersection.Results(a) No study that directly tests the role of alexithymia in conjunction with other potential risk factors for recidivism and actual violent recidivism was uncovered. (b) Primarily alexithymia researchers and primarily researchers into violence have separately found several clinical features in common between aspects of alexithymia and violence, such as impulsivity (total n = 24 studies). (c) Other researchers have established a relationship between alexithymia and both dynamic and static risk factors for violent recidivism (n = 16 studies).ConclusionAlexithymia may be a possible moderator of risk of violent offence recidivism. Supplementing offenders' rehabilitation efforts with assessments of alexithymia may assist in designing individually tailored interventions to promote desistance among violent offenders.

ABSTRACTAimClinical outcomes after percutaneous coronary intervention (PCI) in hemodialysis (HD) patients are significantly worse than those in non‐HD patients. Optical coherence tomography (OCT) is a high resolution imaging modality and provides a detailed assessment of post‐interventional abnormal findings that influence worse clinical outcomes. However, little is known about the abnormal post‐stent OCT findings in HD patients. Therefore, in this study, we compared the abnormal post‐stent OCT findings between HD and non‐HD patients.MethodsOne hundred thirty‐nine consecutive OCT guided PCI (21 lesions in HD patients and 118 lesions in non‐HD patients) were enrolled. We compared the post‐stent OCT findings, including the edge dissections, under expansion index (minimum stent area/mean reference area), and stent eccentricity index (minimum stent diameter/maximum stent diameter) between HD and non‐HD patients. We also compared the device‐oriented clinical events (DoCEs) at 8 months of follow up.ResultsThere was a significantly higher prevalence of distal edge dissections (16.7% vs. 2.8%, P = 0.011) in HD patients. HD patients had a significantly lower under expansion index (0.76 ± 0.21 vs. 0.85 ± 0.14, P = 0.029) and stent eccentricity index (0.82 ± 0.09 vs. 0.88 ± 0.18, P = 0.018). The cumulative rate of DoCEs was significantly higher in the HD patients (23.8% vs. 5.2%, P = 0.013).ConclusionsA higher prevalence of distal edge dissections, under expansion and stent eccentricity were detected by the detailed OCT findings in HD patients.

AbstractObjectiveTo compare the transpedal approach to established femoral approach for endovascular treatment of infrainguinal peripheral arterial disease.BackgroundEndovascular treatment of infrainguinal peripheral arterial disease is on the rise. Femoral approach is widely used but has significant complications. Recently the primary transpedal approach has been described for endovascular interventions. We hypothesized that transpedal approach could reduce access site related complications. We compared the two approaches in a retrospective cross‐sectional study at a single center.MethodsWe analyzed demographics, procedural parameters, and complications in patients who underwent a primary transpedal approach for infrainguinal intervention and compared to patients with a traditional femoral approach in our outpatient based endovascular lab.ResultsThe success rate for access was lower in transpedal group compared to femoral (94% vs. 100%, p = .0002). The contrast dose (44 ± 11 mL vs. 68 ± 13 mL, p < .0001), radiation dose (25 mGy [16–43] vs. 48 mGy [36–67], p < .0001) and fluoroscopy time (5.48 min [3.48–11.71] vs. 9.35 min [6.63–14.11], p < .0001) were significantly lower in transpedal group.ConclusionThe transpedal approach for infrainguinal revascularization appears to be a reasonable primary approach with high success and low complication rate with significant reduction in radiation and contrast dose. These findings should be further studied in a randomized controlled trial.

Published: March 2019

AbstractA 73‐year‐old man with severe, symptomatic secondary mitral regurgitation (MR) underwent successful transcatheter mitral valve replacement using the Tendyne™ mitral valve system. The device was deployed from the left ventricular (LV) apex and secured in position by a tether attached to an epicardial pad. Three days postoperatively, the patient developed hemolytic anemia and a paravalvular leak (PVL) associated with indentation of the LV apex. Adjustment of the tether tension and placement of an epicardial disc under the pad resulted in reduction in the PVL, and resolution of the hemolytic anemia.

AbstractBackgroundPercutaneous recanalization of coronary chronic total occlusions (CTOs) traditionally relies on the use of dual‐access and large bore catheters, with trans‐femoral approach adoption in most cases.ObjectivesAim of this manuscript is to describe the outcomes of an alternative hybrid algorithm, called “Minimalistic Hybrid Algorithm,” which has the purpose to minimize the use of double access, large bore catheters, and femoral approach in order to minimize the risk of vascular complications and patient's discomfort, without compromising efficacy.MethodsIn this single‐center registry, a “minimalistic” approach was attempted in consecutive patients undergoing CTO PCI between March 2016 and October 2017. Data regarding the applicability of this algorithm and the related procedural success rates were collected, together with common demographic and angiographic characteristics.ResultsOf the 100 CTO PCI performed in the study period, 91(91%) were successfully approached according to the novel algorithm. Mean J‐CTO score of all minimalistic procedures was 1.9 ± 1.2, with 31(34%) patients presenting with J‐CTO score ≥3. In 52 procedures, the approach consisted of single‐catheter access, 49(94.2%) of which were trans‐radial. Out of the 39 patients approached with dual‐catheters, 26(69.2%) were biradial, and 8(21%) radial‐femoral. Procedural success in patients approached with the minimalistic algorithm was 89%, in line with the results of large‐multicenter experiences nowadays available.ConclusionsOur results show that an alternative algorithm limiting the routine use of large bore catheters and trans‐femoral approach is feasible in the clinical practice and yields good procedural outcomes.

Published: March 2019

AbstractBackground and objectivesThe quantity and functionality of proteins in different sizes of broken rice (brokens) may inform the different pasting properties observed in rice flour derived from brokens. This study was conducted to determine properties of protein from size‐fractionated parboiled and nonparboiled milled broken rice kernels. In addition, the research sought to determine the extent to which properties of proteins influence functionality of rice flour derived from the studied brokens.FindingsWhole kernels and medium brokens of nonparboiled rice recorded the highest quantity and yield of protein isolate, while the lowest was recorded in large brokens. A strong negative correlation existed between sample protein content and the size of parboiled brokens. Parboiled samples had decreased protein extractability than nonparboiled samples. Emulsifying activity (EA) of parboiled rice had a significantly strong negative linear association with size of brokens. Emulsifying stability (ES) on the other hand had a significantly strong positive linear association with size of brokens, and about 82% of the variation in ES was explained by size. The trend was opposite in the nonparboiled stream with ES having a strong negative linear association with size. A very strong positive linear association existed between foaming capacity (FC), foaming stability (FS), and size of nonparboiled samples. Surface hydrophobicity (SH) was significantly different among parboiled and nonparboiled rice, with weak positive correlations existing between SH and size of parboiled and nonparboiled samples. Solubility curves in nonparboiled stream were more uniform than the parboiled stream. Strong significant positive correlations existed between peak, trough, breakdown, final, setback viscosities, and ES. A strong positive linear association was observed between peak, trough, final viscosities, and FS. Differences in protein contents of whole kernels and size‐fractionated brokens may be attributed to either the variations in the distribution of inherent components of the kernel or variations in milling efficiency. Results in this research are specific for long‐grain hybrid rice and may vary depending on cultivar and environmental factors.ConclusionsProteins influence the pasting properties of brokens. Understanding the functional properties of size‐fractionated broken rice kernels from parboiled and nonparboiled streams is essential in directing the right kind of brokens to the right end‐use.Significance and noveltyThis study provides useful information to better utilization and value addition of brokens.

Published: March 2019

AbstractIron mediated catalytic reactions are of great interest in the field of organic synthesis because they are economic and naturally abundant. However, the use of iron catalyst in the field of free radical cyclization or reduction of alkyl halides remains limited. Here we describe the use of an unprecedented combination of iron and zinc in the reduction and 5‐exo‐trig radical cyclization of alkyl halides under mild condition in the absence of added ligands or additives. The method is distinguished by its wide scope, functional group tolerance and the use of 1,4‐cyclohexadiene as the source of hydrogen, which aids easy purification.

Published: March 2019

AbstractCooling crystallization was successfully carried out in a batch cooling crystallizer from impure acidic solutions to recover nickel as nickel sulfate salt with three different cooling rates. The compositions of the solutions included impurities of sodium, magnesium, chloride, and sulfuric acid to mimic industrial nickel electrowinning process solutions. The results show that NiSO4·6H2O mainly crystallized, and its solubility and purity decreased with the increase in the mass ratio of chloride to sulfate. Cooling rates did not have a significant influence on crystal purity; however, it did affect the filter cake moisture; lower moisture can be obtained with a lower cooling rate. The sequence of impurity removal efficiency from high to low was Cl > Na > Mg.

Published: March 2019

AbstractSimulation results for continuous vacuum evaporation crystallization obtained by Aspen Plus and experimental results for semi‐batch vacuum evaporation crystallization are presented. In the crystallization experiments, the fixed heat duty was used to compare the water evaporation rates and crystal properties obtained at different pressures. The solution selected was aqueous glycine. It has the ability to form a number of different crystalline polymorphs, which allows it to exhibit a variety of different physical properties while maintaining its chemical properties. X‐ray diffraction results demonstrated that mainly the γ‐crystal form is produced under the conditions applied in vacuum evaporation crystallization.

Published: March 2019

AbstractIn this work we apply a novel and simple methodology to develop a composite that consists of anodic aluminum oxide (AAO) covered by a fluorine‐doped tin oxide (FTO) film. The composite presents suitable morphological and electrical properties to be used as support for water electrooxidation catalysts based on non‐noble metals. AAO substrates were decorated with FTO via spray pyrolysis, followed by deposition of catalyst nanoparticles consisting of a cobalt‐analogue of Prussian Blue that promotes the oxygen evolution reaction. The electrodes were characterized by X‐ray Diffraction, Environmental Scanning Electron Microscopy and resistivity measurements. A promising electrocatalytic activity of the optimized AAO/FTO/PB electrode was observed at neutral pH and ambient conditions. The obtained results open a feasible strategy in the search for competitive water oxidation electrodes based on the combination of earth‐abundant metal catalysts on FTO‐covered anodized alumina supports.
Square Wave Voltcoulommetry Analysis of the Influence of the Electrostatic Environment on the Electrochemical Functionality of Redox Monolayers
Authors: Gonzalez Joaquin , Sequí Jose‐Alfonso 
Published: March 2019

AbstractThe analysis of effects of intermolecular interactions on square wave voltcoulommetric (SWVC) responses of electroactive monolayers under Nernstian conditions is presented. Theoretical expressions are given for the Faradaic and non‐Faradaic charge potential curves in terms of the potential perturbation variables and of the phenomenological interaction parameter G. Simple methods are proposed for determining the total excess of electroactive species, the apparent formal potential and the interaction parameter. The application of these methods to the analysis of the electrochemical behaviour of binary monolayers of ferrocenylundecanethiol/decanethiol at gold and platinum electrodes in two different non‐aqueous solvents allows us to obtain reliable values of the above parameters that clearly improve those determined by using Cyclic Voltammetry. Electrostatic insights into the interaction parameters is provided on the basis of a previously reported model. The importance of the presence of ion pairing processes in the value of the parameter G is discussed. The results obtained with SWVC technique point out the fact that intermolecular interactions are not avoided at low surface excesses of the redox probe, indicating that the impact of electrostatics in the appearance of non‐ideal electrochemical responses depends on the nature of the electrolytic media and on the structure of the monolayer in a complex way.
Ligand‐Based PCET Reduction in a Heteroleptic Ni(bpy)(dithiolene) Electrocatalyst Giving Rise to Higher Metal Basicity Required for Hydrogen Evolution
Authors: Koshiba Keita , Yamauchi Kosei , Sakai Ken 
Published: March 2019

AbstractProton abstraction leading to the formation of a hydride species required to evolve H2 largely relies on the basicity of d orbital of the metal responsible for this action. Here we report that a square‐planar NiII(bpy)(dcbdt) hydrogen evolution catalyst shows substantial acceleration in the proton abstraction rate due to the increased basicity at the filled Ni dz2 orbital after formation of [NiI(bpy−.)(dcbdt)]2− via consecutive two one‐electron reductions (bpy=2,2′‐bipyridine; dcbdt=4,5‐dicyanobenzene‐1,2‐dithiolate). The catalyst is likely to adopt the EECC′ mechanism in which the rate of the first protonation step is by far higher than that of the second step, even though an alternative path requiring another reduction (i. e., ECEC′) remains unexcluded. Our DFT calculations reveal that the first and second reductions are correlated with the electron injection into the metal‐ligand anti‐bonding and π*(bpy) orbitals, respectively, where the latter orbital shows non‐negligible hybridization with the nickel d orbital. In addition, a homoleptic catalyst [NiII(dcbdt)2]2− is shown to adopt the EC′EC mechanism with the rate‐determing step being a hydride forming step, consistent with the largely delocalized nature of the injected electron over the two dcbdt ligands (π*(dcbdt) orbital). This work demonstrates the importance of raising the basicity of the metal d orbital, relevant to promote the proton‐coupled electron transfer (PCET).

Published: March 2019

AbstractSyntheses of very electron‐rich dialkylamino‐substituted 2,2':6',2''‐terpyridines (TPYs) were adapted to moderate scale preparation without tedious purification of intermediates. The key 4'‐bromo‐6,6''‐dimethyl‐2,2':6',2''‐terpyridine‐4,4''‐diyl bisnonaflate is now available in gram quantities. Its nucleophilic aromatic substitution with dimethylamine provided mixtures of 4'‐bromo‐substituted 4,4''‐bis(dimethylamino)‐TPY and the tris(dimethylamino)‐TPY. The bromo compound was used in a Buchwald–Hartwig amination to provide the tris(dimethylamino)‐TPY in excellent yield. The 4'‐bromo substituent was reductively removed to furnish the bis(dimethylamino)‐TPY. The same sequence of reactions with pyrrolidine as nucleophile leads to the hitherto unknown pyrrolidino‐TPYs. Calculations at the MP2(FC)/6–31+G(2d,p)//B98/6‐31G(d) level predict very high methyl cation affinities for compounds of this type, with the 4,4',4''‐tri(pyrrolidin‐1‐yl)‐TPY being the most Lewis basic TPY synthesized to date. The efficiently prepared electron‐rich TPYs should be excellent ligands for many applications.
Synthesis and Self‐Assembly of Mixed‐Graft Block Copolymers
Authors: Le An N. , Liang Ruiqi , Zhong Mingjiang 
Published: March 2019

AbstractMixed‐graft block copolymers (mGBCPs) consist of two or more types of polymeric side chains grafted on a linear backbone in a random, alternating, or pseudo‐alternating sequence. They can phase‐separate with the backbone serving as the interface of the blocks, and the side chains dominate their self‐assembly behavior. mGBCPs are an accessible polymer architecture for exploring the idea of encoding polymer properties through the macromolecular architecture, as there are two distinct structural components that can be tuned: the backbone and the side chains. In this Concept article, the current literature on the synthesis of mGBCPs is reviewed, and the advantages and disadvantages of each synthetic method are noted. The self‐assembly of mGBCPs is also discussed where possible. Finally, directions for future research on mGBCP synthesis and self‐assembly are suggested.

AbstractHerein, we report a general method for quantitative measurement of the configurational stability of the stereogenic nitrogen coordinated to M (II) in the corresponding square planar complexes. This stereochemical approach is quite sensitive to steric and electronic effects of the substituents and shown to work well for Ni(II), Pd(II), and Cu(II) complexes. Structural simplicity of the compounds used, coupled with high sensitivity and reliability of experimental procedures, bodes well for application of this approach in evaluation of chemical stability and stereochemical properties of newly designed chiral ligands for general asymmetric synthesis of tailor‐made amino acids.
Method for determination of optical purity of 2‐arylpropanoic acids using urea derivatives based on a 1,1′‐binaphthalene skeleton as chiral NMR solvating agents: Advantages and limitations thereof

Published: March 2019

AbstractFive optically active urea derivatives (1‐5) were used as NMR solvating agents for analysis of the optical purity of different 2‐arylpropanoic acids commonly used as nonsteroidal anti‐inflammatory drugs. These novel chiral solvating agents were more efficient at discriminating the respective enantiomers of targets than the chiral solvating agents known so far, without the need to add a base for achieving the signal splitting. The advantages and limits of the use of these novel chiral solvating agents were studied.
