The Role of Echocardiography in the Management of Patients Undergoing a Ventricular Assist Device Implantation and/or Transplantation
Heart transplantation (HTx) is a curative treatment for patients with advanced heart failure (HF); however, since transplant opportunities are severely limited due to donor shortage, the left ventricular assist device (LVAD) has become a standard therapy for patients awaiting HTx. The role of echocardiography as a primary imaging modality to monitor the allograft function in transplant recipients as well as to optimize LVAD settings in LVAD recipients has been expanding. The purpose of this review is to highlight the clinical role of echocardiography in the management of patients undergoing LVAD implantation and/or HTx. In particular, we overview (1) how to detect LVAD malfunction and device-associated complication in LVAD recipients and (2) echocardiographic assessments of cardiac allograft rejection in transplant recipients
A Case of Pill-Induced Esophagitis With Mucosal Dissection
With the advance of gastrointestinal endoscopy, pill-induced esophagitis has been detected
more frequently, but the association of mucosal dissection is rare. We reported a case of pill-induced
esophagitis associated with mucosal dissection

Temporal and Spatial Expression Patterns of Bone Morphogenetic Protein 3 in Developing Zebrafish
Bone morphogenetic proteins (BMPs) are important elements in bone biology. We herein report the expression profiles of zebrafish bmp3 (zbmp3) as demonstrated by real-time PCR and in situ hybridization. The expression of zbmp3 was highly detectable by real-time PCR from 1 day post-fertilization (1 dpf) to 2 weeks post-fertilization (2 wpf) and peaked at 1 wpf. For in situ hybridization experiments, zbmp3 was expressed in the otic vesicle at 1 dpf, 2 dpf, 3 dpf, and 5 dpf. It was also expressed in the pharyngeal arches, including the opercle, branchiostegal ray, and pectoral fins, at 2 dpf. Our results suggest that zbmp3 may play an important role in the skeletal biology of developing zebrafish

Charge Exchange X-ray Emission Detected in Multiple Shells of Supernova Remnant G296.1-0.5
Recent high-resolution X-ray spectroscopy revealed possible presence of
charge exchange (CX) X-ray emission in supernova remnants (SNRs). Although CX
is expected to take place at outermost edges of SNR shells, no significant
measurement has been reported so far due to the lack of nearby SNR samples.
Here we present an X-ray study of SNR G296.10.5, which has a complicated
multiple-shell structure, with the Reflection Grating Spectrometer (RGS)
onboard XMM-Newton. We select two shells in different regions and find that in
both regions O VII line shows a high forbidden-to-resonance () ratio that
cannot be reproduced by a simple thermal model. Our spectral analysis suggests
a presence of CX and the result is also supported by our new radio observation,
where we discover evidence of molecular clouds associated with these shells.
Assuming G296.10.5 has a spherical shock, we estimate that CX is dominant in
a thin layer with a thickness of 0.2--0.3\% of the shock radius. The result is
consistent with a previous theoretical expectation and we therefore conclude
that CX occurs in G296.10.5.Comment: 11 pages, 8 figure
