Compression methods after femoral artery puncture: A protocol for systematic review and network meta-analysis.

Background: Vascular complications at the puncture site is a common complication after femoral artery puncture. It will not only affect the postoperative effect and patient comfort, but also may endanger the life of the patient. The effective compression hemostasis methods at the puncture site can improve the comfort of the patient, shorten the hospital stay, and reduce the burden on the medical staff.

Protective effect of propofol on hydrogen peroxide-induced human esophageal carcinoma via blocking the Wnt/β-catenin signaling pathway.

Objectives: To analyze the potential influences of propofol on the oxidative stress of HO-induced human esophageal squamous cell carcinoma (ESCC) Eca109 cell through mediating the Wnt/β-catenin signaling pathway.

Materials And Methods: Eca109 cells were classified into 5 groups: Control group, HO group, Propofol + HO group, Dkk1 (Dickkopf-1, Wnt/β-catenin pathway antagonist) + HO group, and Propofol + LiCl (Lithium chloride, Wnt/β-catenin pathway agonist) + HO group. Western blotting was performed to determine the protein expressions, flow cytometry to measure the content of ROS, immunofluorescence staining to detect the oxidative DNA damage, as well as MTT, AnnexinV-FITC/PI, Wound-healing, and Transwell assays to test the biological characteristics of Eca109 cells.

Combining the Masking and Scaffolding Modalities of Colloidal Crystal Templates: Plasmonic Nanoparticle Arrays with Multiple Periodicities.

Surface patterns with prescribed structures and properties are highly desirable for a variety of applications. Increasing the heterogeneity of surface patterns is frequently required. This work opens a new avenue toward creating nanoparticle arrays with multiple periodicities by combining two generally separately applied modalities (i.

68Ga-labeled cyclic NGR peptide for microPET imaging of CD13 receptor expression.

Peptides containing the asparagines-glycine-arginine (NGR) motif have been identified as specific ligands binding to CD13/aminopeptidase N (APN) receptor, a tumor neovascular biomarker. In this study, we synthesized a novel NGR-containing peptide (NOTA-G3-NGR), and labeled NOTA-G3-NGR with (68)Ga (t1/2 = 67.7 min).

A direct comparison of tumor angiogenesis with ⁶⁸Ga-labeled NGR and RGD peptides in HT-1080 tumor xenografts using microPET imaging.

Peptides containing asparagine-glycine-arginine (NGR) and arginine-glycine-aspartic acid (RGD) sequence are being developed for tumor angiogenesis-targeted imaging and therapy. The aim of this study was to compare the efficacy of NGR- and RGD-based probes for imaging tumor angiogenesis in HT-1080 tumor xenografts. Two PET probes, (68)Ga-NOTA-G₃-NGR2 and ⁶⁸Ga-NOTA-G₃-RGD2, were successfully prepared.

Three-dimensional positron emission tomography/computed tomography analysis of 13NO3- uptake and 13N distribution in growing kohlrabi.

We report the application of three-dimensional positron emission tomography/computed tomography (PET/CT) for the analysis of (13)NO(3)(-) uptake and (13)N distribution in growing kohlrabi. The analytical procedures, equipment parameters, and image reconstruction mode for plant imaging were tested and selected. (13)N in growing kohlrabi plants was imaged versus time using both PET movies and PET/CT tomograms.
