Cardiac Magnetic Resonance Versus Single-Photon Emission Computed Tomography for Detecting Coronary Artery Disease and Myocardial Ischemia: Comparison with Coronary Angiography.

Background: This study aimed to compare the diagnostic accuracy of stress single-photon emission computed tomography (SPECT) and stress cardiac magnetic resonance (CMR) for the assessment of coronary artery disease (CAD) in the same patients, using coronary angiography as the reference standard.

Methods: Thirty patients with known or suspected CAD who were referred for exercise SPECT myocardial perfusion imaging (MPI) for the evaluation of myocardial ischemia underwent stress CMR MPI and computed tomography coronary angiography (CTCA) or selective coronary angiography (SCA). The data from the two stress modalities were compared against the data from angiography.

[OPPORTUNITIES OF ULTRASOUND IMAGING FOR VISUALIZATION OF THE SHOULDER JOINT PATHOLOGICAL CHANGES].

Aim of investigation - the assessment of opportunities of ultrasound (US) imaging for visualization of the shoulder joint pathological changes. 100 patients with the pathologies of shoulder joint have been investigated, they included traumatic, degenerative -dystrophic and inflammatory pathologies (tendinitis, tendinosis, tendinopathy, subacromial-subdelatoid bursitis).Ultrasound study performed on ultrasound TOSHIBA xario XG by high linear probe (7,5-12.

KDM4B promotes epithelial-mesenchymal transition through up-regulation of ZEB1 in pancreatic cancer.

Lysine (K)-specific demethylase 4B (KDM4B) is a histone H3K9 demethylase and is reported to activate gene transcription through regulation of chromatin structures. Previous research has revealed that KDM4B plays special regulatory roles in colorectal, prostate and gastric cancers. However, its physiological role in pancreatic cancer remains largely unknown.

Evidence of CD90+CXCR4+ cells as circulating tumor stem cells in hepatocellular carcinoma.

Primary hepatocellular carcinoma (HCC) often invades into vessels and has a distal metastasis at an early stage, resulting in poor prognosis and therapeutic outcome. The metastasis has been attributable to the dissemination of tumor cells into circulation as circulating tumor cells (CTCs). Moreover, cancer stem cells (CSCs) within CTCs, which are termed as circulating tumor stem cells (CTSCs), are critical for formation of distal metastatic tumors.

Dynamic contrast-enhanced (DCE) MRI assessment of microvascular characteristics in the murine orthotopic pancreatic cancer model.

Object: The aim of this study was to assess the dynamic contrast enhanced magnetic resonance imaging (DCE-MRI)-derived pharmacokinetic parameters between two contrast agents in a murine orthotopic pancreatic cancer model and to evaluate the tumor heterogeneity and the potential association between kinetic parameters and angiogenic markers such as the microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression by immunohistochemistry.

Materials And Methods: Human pancreatic adenocarcinoma cell line MIAPaCa-2 was injected into the pancreas of BALB/C nu/nu mice. DCE-MRI was performed using Gd-DTPA and Gd-EOB-DTPA.

Application of 3.0 tesla magnetic resonance imaging for diagnosis in the orthotopic nude mouse model of pancreatic cancer.

The aim of this study was to successfully establish an orthotopic murine model using two different human pancreatic adenocarcinoma cell lines and to propose a 3.0 tesla MRI protocol for noninvasive characterization of this model. SW1990 and MIAPaca-2 tumor cells were injected into the pancreas of BALB/C nu/nu mice.
