A miniaturized bioreactor system for the evaluation of cell interaction with designed substrates in perfusion culture [PDF]

open access: yes, 2012
In tissue engineering, the chemical and topographical cues within three-dimensional (3D) scaffolds are normally tested using static cell cultures but applied directly to tissue cultures in perfusion bioreactors.

Contrast-enhanced ultrasound examination for the assessment of renal perfusion in cats with chronic kidney disease [PDF]

open access: yes, 2017
Background: Contrast-enhanced ultrasound examination (CEUS) is a functional imaging technique allowing noninvasive assessment of tissue perfusion. Studies in humans show that the technique holds great potential to be used in the diagnosis of chronic ...

Myocardial perfusion [PDF]

open access: yesJournal of Magnetic Resonance Imaging, 2006
AbstractNoninvasive cardiac magnetic resonance (CMR) imaging has progressed rapidly over the past few years and will most likely become an integral part of the diagnostic workup of patients with known or suspected coronary artery disease (CAD). In this article the rationale for using perfusion‐CMR is discussed, followed by a summary of current state‐of‐

Subnormothermic Perfusion in the Isolated Rat Liver Preserves the Antioxidant Glutathione and Enhances the Function of the Ubiquitin Proteasome System. [PDF]

open access: yes, 2016
The reduction of oxidative stress is suggested to be one of the main mechanisms to explain the benefits of subnormothermic perfusion against ischemic liver damage. In this study we investigated the early cellular mechanisms induced in isolated rat livers

Automated Detection of Regions of Interest for Brain Perfusion MR Images [PDF]

open access: yes, 2018
Images with abnormal brain anatomy produce problems for automatic segmentation techniques, and as a result poor ROI detection affects both quantitative measurements and visual assessment of perfusion data.

PERFUSE

open access: yesJournal of Pediatric Gastroenterology and Nutrition, 2022
Objectives:PERFUSE is a non‐interventional study of 1233 patients [inflammatory rheumatic disease, n = 496; inflammatory bowel disease (IBD), n = 737] receiving infliximab (IFX) biosimilar SB2 therapy. This analysis describes response to treatment and persistence on SB2 for up to 12 months in pediatric IBD patients (n = 126).Methods:Pediatric IBD ...

Adenovirus-mediated gene transfer to liver grafts: An improved method to maximize infectivity [PDF]

open access: yes, 1998
Background. Adenoviral gene therapy in liver transplantation has many potential applications, but current vector delivery methods to grafts lack efficiency and require high titers. In this study, we attempted to improve gene delivery efficacy using three

High pressure excursion in a radial design oxygenator

open access: yesThe Journal of ExtraCorporeal Technology
Oxygenator high-pressure (HPE) is a phenomenon that can occur during cardiopulmonary bypass (CPB) in which the oxygenator inlet pressure increases rapidly, thereby limiting flow. Most perfusionists globally do not use inlet oxygenator pressure monitoring

Can the ischemic penumbra be identified on noncontrast CT of acute stroke? [PDF]

open access: yes, 2007
<p><b>Background and Purpose:</b> Early ischemic changes on noncontrast CT in acute stroke include both hypoattenuation and brain swelling, which may have different pathophysiological significance.</p> <p><b>Methods:

Inhibition of Trophoblast-Induced Spiral Artery Remodeling Reduces Placental Perfusion in Rat Pregnancy. [PDF]

open access: yes, 2010
Rats harboring the human angiotensinogen and human renin genes develop preeclamptic features in pregnancy. The preeclamptic rats exhibit a deeper trophoblast invasion associated with a reduced resistance index by uterine Doppler.
