Heart MRI Images Analysis in Case of Arrythmogenic Right Ventricular Cardiomyopathy (ARVC)

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is a cause of sudden cardiac death in otherwise healthy young adults. (ARVD/C) is an inherited cardiomyopathy characterized by life-threatening ventricular arrhythmias and slowly progressive ventricular dysfunction. To diagnose ARVC is indicated by the Task Force of ARVC criteria in 1994 and then revised in 2010 set by the WHO/ISFC. To identify clinical characteristics of ARVC using CMR. The design of this study was qualitative descriptive, which was done by the observational method using MRI 1.5 Tesla. The subject was an adult patient who did Cardiac MRI examination in National Cardiovascular Centre Harapan Kita in March 2018. The collected data were diagnostic images of CMR sequence. Then, it compared with the diagnostic criteria of ARVC which was indicated by Task Force. The result of this study of several ARVC diagnostic criteria in Cardiac MRI examination with T1 Black Blood sequence is clear and accurate in indicating the presence of fat infiltration, CINE sequence is clear in visualizing the dilatation in the right ventricle, wall motion abnormalities, accordion sign, bulging, and LGE clearly shows fibrosis. The detection of right ventricular enlargement, fatty infiltration, fibrosis, and wall motion abnormalities in CMR is useful in the diagnosis of ARVC

Nuclear matrix elements for neutrinoless double-beta decay and double-electron capture

A new generation of neutrinoless double beta decay experiments with improved sensitivity is currently under design and construction. They will probe inverted hierarchy region of the neutrino mass pattern. There is also a revived interest to the resonant neutrinoless double-electron capture, which has also a potential to probe lepton number conservation and to investigate the neutrino nature and mass scale. The primary concern are the nuclear matrix elements. Clearly, the accuracy of the determination of the effective Majorana neutrino mass from the measured 0\nu\beta\beta-decay half-life is mainly determined by our knowledge of the nuclear matrix elements. We review recent progress achieved in the calculation of 0\nu\beta\beta and 0\nu ECEC nuclear matrix elements within the quasiparticle random phase approximation. A considered self-consistent approach allow to derive the pairing, residual interactions and the two-nucleon short-range correlations from the same modern realistic nucleon-nucleon potentials. The effect of nuclear deformation is taken into account. A possibility to evaluate 0\nu\beta\beta-decay matrix elements phenomenologically is discussed.Comment: 24 pages; 80 references. arXiv admin note: substantial text overlap with arXiv:1101.214

Loopography Examination for Colon Cancer Cases in Tangerang District Public Hospital

Loopography examination technique is a radiological examination technique in lower digestive tract (colon) by inserting a positive contrast media into the colon through an artificial hole in abdominal area. This examination aims to evaluate the anatomy and physiology function from distal section of colon to anus with ca colon clinical. This research was conducted in radiology installation of Tangerang District General Hospital during November to December 2018, using a qualitative descriptive method with a literature study approach and interview. The results found that loopography examination in Tangerang District General Hospital did not require special preparation. The kind of contrast media used is a water-soluble contrast media such as iohexol with a ratio of 1: 3 mixed with NaCl. This loopography contrast media can be inserted through the clean stoma or anal. The routine projections performed for loopography examination in Tangerang District General Hospital are Plan photos of Abdomen, Antero Posterior (AP) and Lateral. But sometimes Oblique projection is also used as an addition if is less obvious anatomy due to overlap/superposition

Measurement of the double-\beta decay half-life of ^{136}Xe with the KamLAND-Zen experiment

We present results from the KamLAND-Zen double-beta decay experiment based on an exposure of 77.6 days with 129 kg of $^{136}$Xe. The measured two-neutrino double-beta decay half-life of $^{136}$Xe is $T_{1/2}^{2\nu} = 2.38 \pm 0.02(stat) \pm 0.14(syst) \times 10^{21}$ yr, consistent with a recent measurement by EXO-200. We also obtain a lower limit for the neutrinoless double-beta decay half-life, $T_{1/2}^{0\nu} > 5.7 \times 10^{24}$ yr at 90% confidence level (C.L.), which corresponds to almost a five-fold improvement over previous limits.Comment: 6 pages, 4 figures.
