New Techniques in Iatrogenic Coronary Artery Perforation Management Including Umbrella Technique, Case Report.

This case report presents a patient with iatrogenic coronary artery perforation during coronary angioplasty, complicated with a life-threatening cardiac tamponade. Tamponade decompression was achieved via timely pericardiocentesis with direct autotransfusion. The coronary artery perforation itself was initially closed by using the umbrella technique, which involves distal vessel occlusion with angioplasty balloon fragments.

A Comparative Study of Eu-Doped Sillenites: BiSiO (BSO) and BiGeO (BGO).

The spectroscopic properties of Eu-doped BiSiO (BSO) were investigated and compared with that of Eu-doped BiGeO (BGO). The emission properties and the absorption spectra have been measured at 10 K as well as at 300 K (room temperature). Luminescence was detected due to the direct excitation of the D level of Eu, as well as through the excitation of the D level.

Long-lived Paleoproterozoic eclogitic lower crust.

The nature of the lower crust and the crust-mantle transition is fundamental to Earth sciences. Transformation of lower crustal rocks into eclogite facies is usually expected to result in lower crustal delamination. Here we provide compelling evidence for long-lasting presence of lower crustal eclogite below the seismic Moho.

Optical Transitions and Excited State Absorption Cross Sections of SrLaGaO Doped with Ho Ions.

The spectroscopic properties of SrLaGaO (SLO) crystal doped with Ho ions were studied in this work. Absorption, emission spectra and decay dynamics of excited states have been measured and discussed using the Judd-Ofelt model. Photoluminescence emissions were attributed to transitions from the excited D, S, F, I and I multiplet manifolds.

Down-Shifting in the YAM: Ce + Yb System for Solar Cells.

In this work, we investigate Ce to Yb energy transfer in YAlO (YAM) for potential application in solar spectrum down-converting layers for photovoltaic devices. Photoluminescence properties set, of 10 samples, of the YAM host activated with Ce and Yb with varying concentrations are presented, and the Ce to Yb energy transfer is proven. Measurement of highly non-exponential luminescence decays of Ce 5d band allowed for the calculation of maximal theoretical quantum efficiency, of the expected down-conversion process, equal to 123%.

Emplacement and 3D geometry of crustal-scale saucer-shaped intrusions in the Fennoscandian Shield.

Saucer-shaped intrusions of tens of meters to tens of kilometres across have been observed both from surface geological mapping and geophysical observations. However, there is only one location where they have been reported to extend c. 100 km laterally, and emplaced both in a sedimentary basin and the crystalline basement down to 12 km depth.

Prognostic Significance of NT-proBNP Levels in Patients over 65 Presenting Acute Myocardial Infarction Treated Invasively or Conservatively.

Objectives: Assessment of prognostic significance of NT-proBNP level and the effects of invasive (I) and conservative (C) treatment of acute myocardial infarction (AMI) in patients over 65.

Materials And Methods: One-year survival was assessed in 286 consecutive patients with AMI aged 65-100 (79 ± 8) subjected to I or C treatment (136 and 150 individuals), respectively.

Results: 245 (85%) patients survived in-hospital stay: 124 (91.

Temperature dependence of Er³⁺ ionoluminescence and photoluminescence in Gd₂O₃:Bi nanopowder.

Ionoluminescence (IL) and photoluminescence (PL) of trivalent erbium ions (Er(3+)) in Gd2O3 nanopowder host activated with Bi(3+) ions has been studied in order to establish the link between changes in luminescent spectra and temperature of the sample material. IL measurements have been performed with H2 (+) 100 keV ion beam bombarding the target material for a few seconds, while PL spectra have been collected for temperatures ranging from 20 °C to 700 °C. The PL data was used as a reference in determining the temperature corresponding to IL spectra.

Blue emissions in Dy3+ doped Y4Al2O9 crystals for temperature sensing.

Temperature dependent emission spectra and decay times of trivalent dysprosium (Dy3) activated Y4Al2O9 (YAM) crystals have been studied for the first time (to our knowledge). The ratio of emission lines intensity can be used in temperature measurements, as it is not dependent on the variability of absolute intensity. The Boltzmann model was applied for modeling the temperature variation of the 4I15/2 and 4F9/2 states emissions relative intensities 455 and 481 nm, respectively.

[Aspiration thrombectomy during percutaneous coronary intervention in a patient with cardiogenic shock caused by left main occlusion].

Case Study: 56-year-old male patient in cardiogenic shock with a large thrombus in LM, succesfully treated by PTCA with aspiration thrombectomy.

Follow-up: 9 months control angiography.
