Czynniki ryzyka ostrego zespołu wieńcowego u osób z przedwczesną chorobą sercowo-naczyniową

ABSTRACT INTRODUCTION: Cardiovascular diseases (CVDs) are the main cause of death worldwide. In the last 40 years we can observe increase in prevalence of CVDs among young population. [1] Control of risk factors is especially important in young group of patients because the long-term prognosis for this group is particularly unfavorable.[2] MATERIALS AND METHODS: 100 medical records of following patients hospitalized between 2014 - 2017 in Department of Cardiac and Vascular Diseases in Cracow Specialist Hospital were analyzed with special attention to myocardial infarction risk factors. The study included 58 women under the age of 55 and 42 men under 45 divided into two groups with or without acute coronary syndrome (ACS). RESULTS: 86% of examined population had LDL level higher than 1,8 mmol/l, 65% smoked cigarettes and 86,4% had thickened intima-media complex. HDL level was below the norm in 47,4% of the group with ACS and only in 20,9% of the group without ACS (p < 0,05). Significant differences between groups in combined risk factors were observed in decreased HDL level accompanied by increased LDL (40,4% with ACS, 20,9% without ACS), tobacco abuse (38,6% with ACS, 18,6% without ACS) or arterial hypertension (40,4% with ACS, 18,6% without ACS). CONCLUSION: The most important risk factor of acute myocardial infarction in the studied group with early onset of CVD was reduced HDL level.ABSTRACT INTRODUCTION: Cardiovascular diseases (CVDs) are the main cause of death worldwide.

The ICARUS T600 Experiment in the Gran Sasso Underground Laboratory

With a mass of about 600 tons of Liquid Argon (LAr), the ICARUS T600 detector is the biggest, up to now, LAr Time Projection Chamber (TPC). Following its successful test run, on the Earth surface, in Pavia (Italy) in 2001, the detector is now very close to start data taking in the Gran Sasso underground laboratory. The main features of the LAr TPC technique, together with a short discussion of some of the ICARUS T600 test run results, are presented in this paper

The T2K Side Muon Range Detector

The T2K experiment is a long baseline neutrino oscillation experiment aiming to observe the appearance of {\nu} e in a {\nu}{\mu} beam. The {\nu}{\mu} beam is produced at the Japan Proton Accelerator Research Complex (J-PARC), observed with the 295 km distant Super- Kamiokande Detector and monitored by a suite of near detectors at 280m from the proton target. The near detectors include a magnetized off-axis detector (ND280) which measures the un-oscillated neutrino flux and neutrino cross sections. The present paper describes the outermost component of ND280 which is a side muon range detector (SMRD) composed of scintillation counters with embedded wavelength shifting fibers and Multi-Pixel Photon Counter read-out. The components, performance and response of the SMRD are presented.Comment: 13 pages, 19 figures v2: fixed several typos; fixed reference

The SMRD subdetector at the T2K near detector station

The T2K long-baseline neutrino oscillation experiment is running in Japan. The primary goals of the T2K are measurement of the mixing angle 13, and precise measurements of the mixing angle 23 and of the mass difference m2 23. The installation of the near detector complex was completed and first data were already registered. This article presents operation of the Side Muon Range Detector, a component of the Off-Axis near detector. Detector concept and implementation are presented, followed by a description of cosmic muon track reconstruction algorithm and finally current status

Energy reconstruction of electromagnetic showers from [Pi 0] decays with the ICARUS T600 liquid argon TPC

We discuss the ICARUS T600 detector capabilities in electromagnetic shower reconstruction through the analysis of a sample of 212 events, coming from the 2001 Pavia surface test run, of hadronic interactions leading to the production of 0 mesons. Methods of shower energy and shower direction measurements were developed and the invariant mass of the photon pairs was reconstructed. The ( ) invariant mass was found to be consistent with the value of the 0 mass. The resolution of the reconstructed 0 mass was found to be equal to 27.3%. An improved analysis, carried out in order to clean the full event sample from the events measured in the crowded environment, mostly due to the trigger conditions, gave a 0 mass resolution of 16.1%, significantly better than the one evaluated for the full event sample. The trigger requirement of the coincidence of at least four photo-multiplier signals favored the selection of events with a strong pile up of cosmic ray tracks and interactions. Hence a number of candidate 0 events were heavily contaminated by other tracks and had to be rejected. Monte Carlo simulations of events with 0 production in hadronic and neutrino interactions confirmed the validity of the shower energy and shower direction reconstruction methods applied to the real data
