OBJECTIVE To evaluate the utility of multi-slice computed tomography (MSCT) in assessing acute non-reperfused myocardial infarct size. METHODS Seven domestic pigs (mean weight 17.3 ± 1.9 kg) underwent ligation of the distal left anterior descending artery to establish a model of acute myocardial infarction (MI). MSCT and triphenyltetrazolium chloride (TTC) staining were performed two hours la...

Abstract In a previous study from our laboratory, we demonstrated that chronic and selective cardiac sympathetic afferent (spinal) denervation at the time of myocardial infarction (MI) using epicardial application resiniferatoxin (RTX), neuronal toxin capable inducing rapid degeneration transient receptor potential vanilloid 1 (TRPV1)-expressing neurons fibers, markedly reduced remodeling proce...

Matrix metalloproteinases (MMPs) have been studied extensively, and MMP inhibitors have been used as dental pretreatment agents prior to dentin bonding because they reduce collagen fiber degradation and improve bonding strength. However, morphologic characteristics of the collagen network after etching and of the post-adhesive dentin hybrid layers (DHL) after MMP inhibitors pretreatment have no...

Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200 keV, and the microscope operates in the transmission mode. Here, we report the development of scanning ultrafast electron microscopy using a f...

Scanning Electron Microscopy (SEM) is an invaluable tool for biologists and neuroscientists to study brain structure at the intracellular level. While able to image tissue samples with up to 5 nm isotropic resolution, image acquisition is prohibitively slow and limits the size of processed samples. In this work, we propose a novel approach to speeding up imaging when looking for specific struct...

To investigate the small-strain stiffness characteristics of highly weathered granite (HWG), a resonance column test system was used to conduct tests on taken from Lincang City, Yunnan Province, China. The effects effective consolidation stress and structural changes is caused by remodeling process initial dry density HWG. Furthermore, difference between data other geotechnical materials were c...

In the present article, synthesis of zeolite imidazole framework-11 (ZIF-11) by ultrasonic-assisted hydrothermal process and its application as an electrode modifier for electrochemical determination uric acid in urine are demonstrated. The obtained materials were characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption/desorption isotherms. It was found th...
