Application of transition-edge sensors for micro-X-ray fluorescence measurements and micro-X-ray absorption near edge structure spectroscopy: a case study of uranium speciation in biotite obtained from a uranium mine.

In this study, we successfully applied a transition-edge sensor (TES) spectrometer as a detector for microbeam X-ray measurements from a synchrotron X-ray light source in the hard X-ray region to determine uranium (U) distribution at the micro-scale and its chemical species in biotite obtained from a U mine. It is difficult to separate the fluorescent X-ray of the U Lα line at 13.615 keV from that of the Rb Kα line at 13.

Right-sided iliac vein compression syndrome: when the vein is compressed between the internal and external iliac arteries-a case report.

Background: In its normal anatomical relationship, the inferior vena cava is located on the right side of the abdominal aorta. Iliac vein compression syndrome (IVCS) is a pathological condition in which a blood clot is formed due to blood flow obstruction when the left common iliac vein is compressed between the right common iliac artery and the vertebral body. Therefore, right-sided IVCS (RIVCS) is rare.

"Happy Heart Syndrome" Followed Up with Cardiac Magnetic Resonance Imaging.

We herein report a 49-year-old woman who developed "happy heart syndrome" while watching a family theater performance. She was followed up with cardiac magnetic resonance imaging (CMR). The time course of the CMR findings was similar to that previously reported for Takotsubo cardiomyopathy (TTC), including the form of "broken heart syndrome.

Capecitabine May Accelerate Atherosclerosis and Causes Acute Myocardial Infarction in the Left Main Trunk.

We report a case of a 59-year-old man who developed acute myocardial infarction which is supposed to be associated with capecitabine administration. At the age of 57 years, the patient underwent a laparoscopic colectomy for sigmoid colon cancer and subsequently received adjuvant chemotherapy with capecitabine. About one year later, he developed an acute myocardial infarction and was treated with percutaneous coronary intervention.

Proof-of-Principle Experiment for Testing Strong-Field Quantum Electrodynamics with Exotic Atoms: High Precision X-Ray Spectroscopy of Muonic Neon.

To test bound-state quantum electrodynamics (BSQED) in the strong-field regime, we have performed high precision x-ray spectroscopy of the 5g-4f and 5f- 4d transitions (BSQED contribution of 2.4 and 5.2 eV, respectively) of muonic neon atoms in the low-pressure gas phase without bound electrons.
