Bis(3-methyl­phenolato-κO)(nitros­yl-κN)[tris­(3,5-dimethyl­pyrazol-1-yl-κN 2)hydridoborato]molybdenum(II)

The title complex, [Mo(C15H22BN6)(C7H7O)2(NO)], contains an {MoNO}4 core stabilized by κ3­-hydrotris­(3,5-dimethyl­pyrazol-1-yl)borate, [TpMe2]−, and two anionic m-cresolate ligands, leading to a distorted octa­hedral geometry for the Mo atom. The short Mo—O bond lengths [1.935 (2) and 1.971 (2) Å], as well as large Mo—O—Csp 2 angles [134.2 (2) and 143.54 (19)°], indicate dπMo—pπO inter­actions, which are clearly weaker when compared with {Mo(NO)(TpMe2)} alkoxides. The nitrosyl system is virtually linear [179.3 (3)°] with Mo—N and N—O bond lengths of 1.760 (2) and 1.205 (3) Å, respectively. Intra- and inter­molecular C—H(Ph or CH3)⋯π(Ph) inter­actions between adjacent phenyl rings are found in the crystal structure (d H⋯Ph in the range 2.743–2.886 Å). One of the Ph rings shows disorder, i.e. swinging in the ring plane

Twelve months clinical outcome after bioresorbable vascular scaffold implantation in patients with stable angina and acute coronary syndrome : data from the Polish National Registry

Introduction: There are limited data describing bioresorbable vascular scaffold (BVS) implantation in complex lesions. Only short-term clinical outcomes are available for patients with acute coronary syndrome (ACS). Aim: To evaluate 12-month clinical outcome, safety and effectiveness of BVS implantation in complex lesions and in stable angina (SA) or ACS. Material and methods: Five hundred ninety-one patients with SA/ACS were enrolled between October 2012 and November 2013 in 30 invasive cardiology centres in Poland. At least one BVS implantation during percutaneous coronary intervention (PCI) was the only inclusion criteria. The clinical endpoint was the occurrence of a major adverse cardiovascular event (MACE) (all-cause death, myocardial infarction (MI), clinically driven target lesion revascularisation (TLR) with urgent PCI or target vessel revascularisation (TVR) with urgent coronary artery bypass grafting (CABG)) and device-oriented composite endpoint (DOCE) (cardiac death, urgent target vessel revascularisation with PCI/CABG, target vessel MI) during 12-month follow-up. Results: After 12 months TLR with urgent PCI was significantly more often reported in patients with diagnosed UA (4.59%; p < 0.02) in comparison with other PCI indications. No significant differences were found in terms of composite MACE endpoint, cumulative MACE (p = 0.09), stent thrombosis (p = 0.2) or restenosis (p = 0.2). There were no significant differences in cumulative MACE and composite MACE endpoint between patients with no/mild versus moderate/severe tortuosity and no/mild versus moderate/severe calcification of the target vessel. No significant difference was found between groups of patients with or without bifurcation of the target vessel. Device-oriented composite endpoint was significantly more often reported in the ACS group (3.2% vs. 0.47%; p < 0.03), most frequently in patients with diagnosed UA (5.5%). Conclusions: Bioresorbable vascular scaffold can be successfully and safely used for ACS treatment and in lesions of higher complexity

NA61/SHINE facility at the CERN SPS: beams and detector system

NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a multi-purpose experimental facility to study hadron production in hadron-proton, hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton Synchrotron. It recorded the first physics data with hadron beams in 2009 and with ion beams (secondary 7Be beams) in 2011. NA61/SHINE has greatly profited from the long development of the CERN proton and ion sources and the accelerator chain as well as the H2 beamline of the CERN North Area. The latter has recently been modified to also serve as a fragment separator as needed to produce the Be beams for NA61/SHINE. Numerous components of the NA61/SHINE set-up were inherited from its predecessors, in particular, the last one, the NA49 experiment. Important new detectors and upgrades of the legacy equipment were introduced by the NA61/SHINE Collaboration. This paper describes the state of the NA61/SHINE facility - the beams and the detector system - before the CERN Long Shutdown I, which started in March 2013

Comparison of Physicochemical, Mechanical, and (Micro-)Biological Properties of Sintered Scaffolds Based on Natural- and Synthetic Hydroxyapatite Supplemented with Selected Dopants

The specific combinations of materials and dopants presented in this work have not been previously described. The main goal of the presented work was to prepare and compare the different properties of newly developed composite materials manufactured by sintering. The synthetic-(SHAP) or natural- (NHAP) hydroxyapatite serves as a matrix and was doped with: (i) organic: multiwalled carbon nanotubes (MWCNT), fullerenes C60, (ii) inorganic: Cu nanowires. Research undertaken was aimed at seeking novel candidates for bone replacement biomaterials based on hydroxyapatite—the main inorganic component of bone, because bone reconstructive surgery is currently mostly carried out with the use of autografts; titanium or other non-hydroxyapatite -based materials. The physicomechanical properties of the developed biomaterials were tested by Scanning Electron Microscopy (SEM), Dielectric Spectroscopy (BSD), Nuclear Magnetic Resonance (NMR), and Differential Scanning Calorimetry (DSC), as well as microhardness using Vickers method. The results showed that despite obtaining porous sinters. The highest microhardness was achieved for composite materials based on NHAP. Based on NMR spectroscopy, residue organic substances could be observed in NHAP composites, probably due to the organic structures that make up the tooth. Microbiology investigations showed that the selected samples exhibit bacteriostatic properties against Gram-positive reference bacterial strain S. epidermidis (ATCC 12228); however, the property was much less pronounced against Gram-negative reference strain E. coli (ATCC 25922). Both NHAP and SHAP, as well as their doped derivates, displayed in good general compatibility, with the exception of Cu-nanowire doped derivates

System size and centrality dependence of the balance function in A+A collisions at sqrt[sNN]=17.2 GeV

Electric charge correlations were studied for p+p, C+C, Si+Si, and centrality selected Pb+Pb collisions at sqrt[sNN]=17.2 GeV with the NA49 large acceptance detector at the CERN SPS. In particular, long-range pseudorapidity correlations of oppositely charged particles were measured using the balance function method. The width of the balance function decreases with increasing system size and centrality of the reactions. This decrease could be related to an increasing delay of hadronization in central Pb+Pb collisions

Two-particle correlations in azimuthal angle and pseudorapidity in inelastic p + p interactions at the CERN Super Proton Synchrotron

Results on two-particle ΔηΔϕ correlations in inelastic p + p interactions at 20, 31, 40, 80, and 158 GeV/c are presented. The measurements were performed using the large acceptance NA61/SHINE hadron spectrometer at the CERN Super Proton Synchrotron. The data show structures which can be attributed mainly to effects of resonance decays, momentum conservation, and quantum statistics. The results are compared with the Epos and UrQMD models.ISSN:1434-6044ISSN:1434-605
