Cellular responses to beating hydrogels to investigate mechanotransduction

Nature Communications, 2019
Mechanotransduction of cells is of interest for a number of reasons but model in vitro systems remain a challenge. Here, the authors report on a hydrogel which changes properties upon near infrared irradiation to create cyclic forces and demonstrate the ...

Infarct volumes of patients with acute ischemic stroke receiving direct oral anticoagulants due to non-valvular atrial fibrillation

Annals of Indian Academy of Neurology, 2021
Direct oral anticoagulants (DOACs) have been shown to decrease the risk of ischemic stroke in non-valvular atrial fibrillation (NVAF). This study aims to investigate whether DOACs result in a significant change in lesion volume and the severity of the ...

Diagnosis and Management of an Isolated Pediatric Plexiform Neurofibroma Involving the Hepatic and Celiac Plexus Using Multimodality Approach: Problem Solving with Diffusion-Weighted Magnetic Resonance Imaging

European Journal of Pediatric Surgery Reports, 2013
Plexiform neurofibroma with involvement of the gastrointestinal tract is a very rare entity in children. Here, we present a rather unique case of a 9-year-old boy with no clinical signs or features of neurofibromatosis type 1.

Technical advancements and protocol optimization of diffusion-weighted imaging (DWI) in liver [PDF]

, 2016
An area of rapid advancement in abdominal MRI is diffusion-weighted imaging (DWI). By measuring diffusion properties of water molecules, DWI is capable of non-invasively probing tissue properties and physiology at cellular and macromolecular level.

Comparison of TGSE-BLADE DWI, RESOLVE DWI, and SS-EPI DWI in healthy volunteers and patients after cerebral aneurysm clipping

Scientific Reports, 2022
AbstractDiffusion-weighted magnetic resonance imaging is prone to have susceptibility artifacts in an inhomogeneous magnetic field. We compared distortion and artifacts among three diffusion acquisition techniques (single-shot echo-planar imaging [SS-EPI DWI], readout-segmented EPI [RESOLVE DWI], and 2D turbo gradient- and spin-echo diffusion-weighted ...

Comparison of DWI techniques in patients with epidermoid cyst: TGSE-BLADE DWI vs. SS-EPI DWI

Japanese Journal of Radiology
Abstract Purpose To compare quantitative values and image quality between single-shot echo-planar imaging (SS-EPI) diffusion-weighted imaging (DWI) and two-dimensional turbo gradient- and spin-echo DWI with non-Cartesian BLADE trajectory (TGSE-BLADE DWI) in patients with epidermoid cyst.
