OBJECTIVES Virtual Touch tissue quantification (VTQ) is a quantified ultrasound (US) acoustic radiation force impulse (ARFI) imaging method that provides numerical measurements (wave-velocity values) of tissue stiffness. The purpose of this study was to detect whether VTQ could be applied to differentiate between benign and malignant thyroid lesions. (More)
RATIONALE AND OBJECTIVES To detect whether the efficacy of microwave ablation (MWA) could be improved by preinjected fluids in an ex vivo porcine liver model. MATERIALS AND METHODS Ablations were performed for 12 minutes using energy output of impedance-based (power output gradually rose to 200W, maintained until increases in tissue impedance of 20 Ω,(More)
OBJECTIVE To determine T box expressed in T cells (T bet), GATA binding protein-3 (GATA 3), and retinoid-related orphan nuclear receptor gammat (RORgammat) in rats with chronic obstructive pulmonary disease (COPD). METHODS Thirty rats were randomly divided into a control and a COPD group. The COPD model was established through smoking and(More)
TGF-β-induced epithelial-mesenchymal transition (EMT) plays an important role in tumor progression. We assessed whether the TGF-β-induced EMT contributed to vasculogenic mimicry (VM) formation in glioma, we established an SHG44 cell line stably transfected with TGF-β cDNA loaded lentivirus. SB203580 was employed to inhibit the TGF-β-induced EMT. The results(More)
Objective. The purpose of the study was to assess the application value of VTQ in DTD. Research Design and Methods. Thirty healthy subjects and 74 DTD patients were involved. The thyroid stiffness, which was expressed by SWV, was measured by VTQ and compared between the patients and healthy people. The relationship between SWV and thyroid serological(More)
The purpose of this study was to distinguish passive retention of microbubbles in liver sinusoids from active intracellular retaining, and to provide further evidence of post vascular liver specific phase of perflubutane microbubble contrast-enhanced ultrasound for potential use in the detection of focal liver lesions. Fifty-four rats were divided into(More)
Nuclear receptor binding protein 1 (NRBP1) is a highly conserved protein that is ubiquitously expressed across cell types in humans. NRBP1 has been recently identified as an adaptor protein. It has been suggested that it plays important roles in cellular homeostasis and the pathophysiology of cancer. To determine whether NRBP1 is involved in the(More)
We determined the ability of contrast-enhanced ultrasound (CEUS) using perflubutane microbubbles to diagnose liver fibrosis and cirrhosis in rats using histology as the reference standard. Fibrosis was induced by oral administration of carbon tetrachloride to 32 Wistar rats. Features with baseline ultrasound (US) and enhancement level of liver and spleen(More)
