High‐temperature study of superconducting hydrogen and deuterium sulfide
Authors: Durajski A.P. , Szczȩśniak R. , Pietronero L. 
Published: December 2015

Hydrogen‐rich compounds are extensively explored as candidates for a high‐temperature superconductors. Currently, the measured critical temperature of 203 K in hydrogen sulfide (H3S) is among the highest over all‐known superconductors. In present paper, using the strong‐coupling Eliashberg theory of superconductivity, we compared in detail the thermodynamic properties of two samples containing different hydrogen isotopes H3S and D3S at 150 GPa. Our research indicates that it is possible to reproduce the measured values of critical temperature 203 K and 147 K for H3S and D3S by using a Coulomb pseudopotential of 0.123 and 0.131, respectively. However, we also discuss a scenario in which the isotope effect is independent of pressure and the Coulomb pseudopotential for D3S is smaller than for H3S. For both scenarios, the energy gap, specific heat, thermodynamic critical field and related dimensionless ratios are calculated and compared with other conventional superconductors. We shown that the existence of the strong‐coupling and retardation effects in the systems analysed result in significant differences between values obtained within the framework of the Eliashberg formalism and the prediction of the Bardeen‐Cooper‐Schrieffer theory.
Cobalt(II) Porphyrin‐Catalyzed Intramolecular Cyclopropanation of N‐Alkyl Indoles/Pyrroles with Alkylcarbene: Efficient Synthesis of Polycyclic N‐Heterocycles

Published: December 2015

AbstractA protocol on chemoselective cobalt(II) porphyrin‐catalyzed intramolecular cyclopropanation of N‐alkyl indoles/pyrroles with alkylcarbenes has been developed. The reaction enables the rapid construction of a range of nitrogen‐containing polycyclic compounds in moderate to high yields from readily accessible materials. These N‐containing polycyclic compounds can be converted into a variety of N‐heterocycles with potential synthetic and biological interest. Compared to their N‐tosylhydrazone counterparts, the use of bulky N‐2,4,6‐triisopropylbenzenesulfonyl hydrazones as carbene precursors allows cyclopropanation to occur under milder reaction conditions.

AbstractOxide‐derived copper (OD‐Cu) electrodes exhibit unprecedented CO reduction performance towards liquid fuels, producing ethanol and acetate with >50 % Faradaic efficiency at −0.3 V (vs. RHE). By using static headspace‐gas chromatography for liquid phase analysis, we identify acetaldehyde as a minor product and key intermediate in the electroreduction of CO to ethanol on OD‐Cu electrodes. Acetaldehyde is produced with a Faradaic efficiency of ≈5 % at −0.33 V (vs. RHE). We show that acetaldehyde forms at low steady‐state concentrations, and that free acetaldehyde is difficult to detect in alkaline solutions using NMR spectroscopy, requiring alternative methods for detection and quantification. Our results represent an important step towards understanding the CO reduction mechanism on OD‐Cu electrodes.

Published: December 2015

AbstractA supramolecular strategy for detecting specific proteins in complex media by using hyperpolarized 129Xe NMR is reported. A cucurbit[6]uril (CB[6])‐based molecular relay was programmed for three sequential equilibrium conditions by designing a two‐faced guest (TFG) that initially binds CB[6] and blocks the CB[6]–Xe interaction. The protein analyte recruits the TFG and frees CB[6] for Xe binding. TFGs containing CB[6]‐ and carbonic anhydrase II (CAII)‐binding domains were synthesized in one or two steps. X‐ray crystallography confirmed TFG binding to Zn2+ in the deep CAII active‐site cleft, which precludes simultaneous CB[6] binding. The molecular relay was reprogrammed to detect avidin by using a different TFG. Finally, Xe binding by CB[6] was detected in buffer and in E. coli cultures expressing CAII through ultrasensitive 129Xe NMR spectroscopy.

Published: December 2015

AbstractAminopeptidase N (APN) is an important enzyme that is involved in tumor angiogenesis. Detection of APN activity can thus lead to early diagnosis and elucidation of tumor development. Although some molecular probes for APN have been developed, the detection of APN activity in opaque biological samples remains a challenge. To this end, we designed a hyperpolarized NMR probe [1‐13C]Ala‐NH2 which satisfies the prerequisites for APN detection, namely, sufficient retention of the hyperpolarized state, a high reactivity to APN, and an APN‐induced chemical shift change. The [1‐13C]Ala‐NH2 probe allowed sensitive detection of APN activity using 13C NMR spectroscopy.

AbstractSirtuine spalten NAD+‐abhängig Acylreste von Lysinen in Proteinen ab. Eine Fehlregulation von humanem Sirt2 wurde mit der Entstehung von Krebs, entzündlichen und neurodegenerativen Erkrankungen in Verbindung gebracht, was es zu einem vielversprechenden Zielprotein für die Wirkstoffforschung macht. Hier präsentieren wir die Entwicklung der ersten Sirt2‐selektiven Affinitätssonde auf Basis einer Kristallstruktur von Sirt2 in Komplex mit einem optimierten Hemmstoff aus der Klasse der SirReals (“Sirtuin Rearranging Ligands”). Dieser zeigt verbesserte Wirkpotenz, Wasserlöslichkeit und zelluläre Wirksamkeit. Die langsame Dissoziation des Enzym‐Sonden‐Komplexes ermöglicht die Erschließung neuer Anwendungsgebiete für die SirReals, darunter biophysikalische Charakterisierungsmethoden, fragmentbasiertes Wirkstoffscreening und Pull‐Down‐Experimente. Dies macht unsere SirReal‐Sonde zu einem wertvollen Werkzeug für weiterführende Studien in der Sirtuin‐Biologie.
Stepwise Versus Concerted Mechanisms in General‐Base Catalysis by Serine Proteases
Authors: Uritsky Neta , Shokhen Michael , Albeck Amnon 
Published: December 2015

AbstractGeneral‐base catalysis in serine proteases still poses mechanistic challenges despite decades of research. Whether proton transfer from the catalytic Ser to His and nucleophilic attack on the substrate are concerted or stepwise is still under debate, even for the classical Asp‐His‐Ser catalytic triad. To address these key catalytic steps, the transformation of the Michaelis complex to tetrahedral complex in the covalent inhibition of two prototype serine proteases was studied: chymotrypsin (with the catalytic triad) inhibition by a peptidyl trifluoromethane and GlpG rhomboid (with Ser‐His dyad) inhibition by an isocoumarin derivative. The sampled MD trajectories of averaged pKa values of catalytic residues were QM calculated by the MD‐QM/SCRF(VS) method on molecular clusters simulating the active site. Differences between concerted and stepwise mechanisms are controlled by the dynamically changing pKa values of the catalytic residues as a function of their progressively reduced water exposure, caused by the incoming ligand.

Published: December 2015

ABSTRACTIn this study, we investigated the effects of the number of high pressure homogenization cycles and alginate (AG)‐to‐chitosan (CS) ratio on the physicochemical properties (mean size, polydispersity index, surface charge, encapsulation efficiency, and free radical scavenging) of (‐)‐epigallocatechin‐3‐gallate (EGCG)‐loaded nanoparticles. Nanoparticles prepared with alginate and chitosan concentrations of 0.01% and three cycles of high pressure homogenization exhibited a small size (293 nm) and a zeta potential of +37.49 mV, and were thus considered to be optimal for encapsulation. The highest encapsulation efficiency of 80.1% was achieved by using an EGCG concentration of 100 µg/g, which also resulted in the highest 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging activities of 81.8% and 69.3% for pH 2.6 and pH 6.9, respectively. © 2015 Wiley Periodicals, Inc.

BACKGROUNDA total of 75% of monozygotic twins share 1 monochorionic placenta where placental anastomoses cause several serious complications, for example, acardiac twinning. Acardiac twins lack cardiac function but grow by perfusion of arterial blood from the pump twin. This rare pregnancy has 50% natural pump twin mortality but accurate risk prediction is currently impossible. Recent guidelines suggest prophylactic surgery before 18 weeks, suggesting 50% unnecessary interventions. We hypothesize that (1) adverse pump twin outcome relates to easy‐to‐measure pump/acardiac umbilical venous diameter (UVD) ratios, representing acardiac perfusion by the pump's excess cardiac output. This hypothesis suggests that (2) UVD‐ratios are large, mildly varying in cases without complications but small and decreasing when complications develop, thus predicting that (3) UVD‐ratios may allow risk prediction of pump twins. In this exploratory clinical pilot, we tested whether UVD‐ratio measurements support these predictions.METHODSWe included 7 uncomplicated (expectant management), 3 elective surgical, and 17 complicated cases (pump decompensation, emergency intervention/delivery or demise). Nine UVD‐ratios were measured sonographycally and 18 by pathology.RESULTSUncomplicated cases have larger, two serial measurements showing mildly varying UVD‐ratios; elective surgical cases show larger UVD‐ratios; complicated cases have smaller, two serial measurements showing decreasing UVD‐ratios. There were no false‐positives, no false‐negatives and noncrossing linear trendlines of uncomplicated and complicated cohorts.CONCLUSIONOur data provide first evidence that UVD‐ratios allow risk prediction of pump twins. More early uncomplicated and late complicated cases are needed, for example, in a prospective trial, before the separation between uncomplicated and complicated cohorts is accurate enough to support a well‐founded decision on (early) intervention.

Relaxed Poisson cure rate models
Authors: Rodrigues Josemar , Cordeiro Gauss M. , Cancho Vicente G. , Balakrishnan N. 
Published: December 2015

The purpose of this article is to make the standard promotion cure rate model (Yakovlev and Tsodikov, ) more flexible by assuming that the number of lesions or altered cells after a treatment follows a fractional Poisson distribution (Laskin, ). It is proved that the well‐known Mittag‐Leffler relaxation function (Berberan‐Santos, ) is a simple way to obtain a new cure rate model that is a compromise between the promotion and geometric cure rate models allowing for superdispersion. So, the relaxed cure rate model developed here can be considered as a natural and less restrictive extension of the popular Poisson cure rate model at the cost of an additional parameter, but a competitor to negative‐binomial cure rate models (Rodrigues et al., ). Some mathematical properties of a proper relaxed Poisson density are explored. A simulation study and an illustration of the proposed cure rate model from the Bayesian point of view are finally presented.

AbstractNAB2‐STAT6 gene fusion drives STAT6 nuclear expression and is the pathognomonic hallmark of solitary fibrous tumors (SFTs). However, no study has systematically analyzed the clinicopathological features, STAT6 immunoexpression status, or the fusion variants of NAB2‐STAT6 in intrathoracic SFTs. Fifty‐two intrathoracic SFTs were retrieved to appraise histopathology, assess STAT6 immunoexpression, and determine NAB2‐STAT6 fusion variants by RT‐PCR. Location‐relevant histologic mimics served as controls. Thirty‐one pleura‐based, 12 mediastinal/pericardial, and nine intrapulmonary lesions were histologically categorized into eight malignant, eight atypical, and 36 conventional or cellular SFTs, including two fat‐forming and two giant cell angiofibroma‐like SFTs. STAT6 distinctively decorated the tumoral nuclei in 51 (98%) SFTs. However, no nuclear staining was observed in the histological mimics. NAB2‐STAT6 fusion was detected in 34 SFTs. Twenty‐nine (85.3%) exhibited the major NAB2ex4‐STAT6ex2/3 variant and 5 (14.7%) the minor NAB2ex6‐STAT6ex16/17. NAB2ex4‐STAT6ex2 was significantly associated with older age (P = 0.01) and pleuropulmonary tumors (P = 0.025). After a median follow‐up of 33.9 (range, 0.3–174.6) months, adverse outcomes occurred in one atypical and five malignant SFTs, including two local relapses, one intrapulmonary metastasis, and three extrathoracic metastases. Inferior disease‐free survival was univariately associated with atypical/malignant histology (P = 0.001) and a mitosis >4/10 HPFs (P = 0.0012) but was unrelated to fusion variants. In conclusion, the majority of intrathoracic SFTs exhibited STAT6 nuclear staining, and NAB2ex4‐STAT6ex2/3 was the predominant fusion type. However, clinical aggressiveness is associated with atypical/malignant histology primarily contributed by increased mitosis but was unrelated to the NAB2‐STAT6 fusion variants.
Effect of Shear Stress on Deoiling of Oil‐Contaminated Catalysts in a Hydrocyclone
Authors: Xu Yin‐xiang , Liu Yi , Zhang Yan‐hong , Yang Xue‐jing , Wang Hua‐lin 
Published: December 2015

AbstractShear stress provided by a hydrocyclone was employed to remove the oil from oil‐contaminated catalysts. Understanding the deoiling mechanism and quantitative analysis of the interaction between shear stress fields and deoiling are necessary to improve deoiling efficiency. A numerical simulation was conducted for the velocity field and shear stress field of a hydrocyclone. The shear stress field in the wall layer, where oil‐contaminated catalysts are usually located, was robust. Increasing inlet flow rates resulted in a higher shear rate distribution along the wall layer. Numerical results were compared with experimental data. In the deoiling process, higher shear stress rates promoted faster transport of oil from catalysts into the fluid, thereby increasing the deoiling efficiency. Deoiling by the shear stress of a hydrocyclone is an efficient method for cleaning oil‐contaminated catalysts within a short time.
Alkali‐Metal‐Ion‐Assisted Hydrogen Atom Transfer in the Homocysteine Radical

Published: December 2015

AbstractIntramolecular hydrogen atom transfer (HAT) was examined in homocysteine (Hcy) thiyl radical/alkali metal ion complexes in the gas phase by combination of experimental techniques (ion‐molecule reactions and infrared multiple photon dissociation spectroscopy) and theoretical calculations. The experimental results unequivocally show that metal ion complexation (as opposed to protonation) of the regiospecifically generated Hcy thiyl radical promotes its rapid isomerisation into an α‐carbon radical via HAT. Theoretical calculations were employed to calculate the most probable HAT pathway and found that in alkali metal ion complexes the activation barrier is significantly lower, in full agreement with the experimental data. This is, to our knowledge, the first example of a gas‐phase thiyl radical thermal rearrangement into an α‐carbon species within the same amino acid residue and is consistent with the solution phase behaviour of Hcy radical.
