Comparison between postprocessing software and repeated scanning to eliminate subdiaphragmatic activity in myocardial perfusion scintigraphy

open access: yesWorld Journal of Nuclear Medicine, 2016
Myocardial perfusion single photon emission computed tomography (SPECT) is a powerful test of evaluation for coronary artery disease, but subdiaphragmatic radiotracer activity often interferes with the interpretation of inferior wall findings. This study

Boron‐Doped Nano‐Crystalline Coated Carbon Fibers for Phasic Dopamine Sensing

open access: yesAdvanced Healthcare Materials, EarlyView.
This uniform coating presents a mix of graphitic and diamond‐like carbon to create a mechanically and electrically robust alternative for the electrochemical detection of dopamine. The electrodes in this work possess the equivalent sensitivity to the state‐of‐the‐art FSCV dopamine detecting electrodes, whilst demonstrating an ability to withstand ...

THE MODERN POSSIBILITIES OF COMPUTED TOMOGRAPHY IN THE VISUALIZATION OF ACUTE PANCREATITIS

open access: yesВестник рентгенологии и радиологии, 2018
Computed tomography (CT) with bolus contrast enhancement is the  main method of objectifying pancreatic pathology in pancreatic necrosis.  This is due to sufficiently high diagnostic accuracy, good  accessibility of the method, fast scanning time, simple

Hybrid Scaffolds Decouple Biochemical & Biophysical Regulation of Cell Phenotype

open access: yesAdvanced Healthcare Materials, EarlyView.
Replicating tissue‐specific extracellular matrix is crucial for understanding its role in disease. This work demonstrates independent control over stiffness, composition and 3D collagen architecture using hybrid scaffolds: patterned collagen perfused with defined hydrogels.

Mesenchymal Stem Cell‐Derived Apoptotic Micro‐Vesicles Repaired Sciatic Nerve Defect by Regulating Early Inflammatory Microenvironment and Promoting Angiogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
HUCMSC‐Apo‐mvs enhance peripheral nerve repair by modulating the inflammatory microenvironment (IME), primarily through coordinated actions on three functional cells. They recruit macrophages and promote their polarization from pro‐inflammatory M1 to anti‐inflammatory M2 phenotypes, increasing secretion of IL‐10 and VEGF.

Human Brain Vasculature‐on‐a‐Chip Model Constructed With Microvessels Isolated From Cryopreserved Postmortem Human Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
This manuscript describes the cultivation of viable microvessels from cryopreserved human brain tissue. When embedded in hydrogels and cultured in microfluidic devices, these microvessels exhibit complex architectures reminiscent of arterioles and capillaries, can be perfused, and display intact barrier function. Collectively, these results demonstrate
