Detection of perfusion ROI as a quality control in perfusion analysis [PDF]

in Proc. Science, Research, Development. Technics and Technology, Berlin, Germany, Jan 30, 2018, pp.57-59, 2019
In perfusion analysis automated approaches for image processing is preferable due to reduce time-consuming tasks for radiologists. Assessment of perfusion results quality is important step in development of algorithms for automated processing. One of them is an assessment of perfusion maps quality based on detection of perfusion ROI.

Outermost Cationic Surface Charge of Layer‐by‐Layer Films Prevents Endothelial Cells Migration for Cell Compartmentalization in Three‐Dimensional Tissues

Advanced Science, EarlyView.
A nanometer‐sized artificial basement membrane (A‐BM) is developed to replicate the barrier functions of the basement membrane and prevent cell migration. It is demonstrated that the outermost cationic surface charge of nanofilms can effectively inhibit endothelial cell migration and sprouting, allowing for the construction of 3D patterned vascular ...

Perfusion Linearity and Its Applications [PDF]

arXiv, 2010
Perfusion analysis computes blood flow parameters (blood volume, blood flow, mean transit time) from the observed flow of contrast agent, passing through the patient's vascular system. Perfusion deconvolution has been widely accepted as the principal numerical tool for perfusion analysis, and is used routinely in clinical applications.

Fish Swim Bladder‐Derived ECM Hydrogels Effectively Treat Myocardial Ischemic Injury through Immunomodulation and Angiogenesis

Advanced Science, EarlyView.
A unique hydrogel based on extracellular matrix from fish swim bladder, which is suitable for transcatheter delivery and possesses remarkable reparative capabilities for treating heart failure, is developed. It emerges as a multi‐effect factor profoundly influencing inflammation regulation, angiogenesis, and myocardial metabolism.

Intestinal absorption of the wheat allergen gliadin in rats

Allergology International, 2019
Background: Aspirin enhances food allergy symptoms by increasing absorption of ingested allergens. The objective of this study is to elucidate the role of aspirin in facilitating intestinal absorption of the wheat allergen, gliadin, in rats.

Tipping Elements in the Human Intestinal Ecosystem [PDF]

, 2014
Recent studies show that the microbial communities inhabiting the human intestine can have profound impact on our well-being and health. However, we have limited understanding of the mechanisms that control this complex ecosystem. Based on a deep phylogenetic analysis of the intestinal microbiota in a thousand western adults we identified groups of ...

Selective evaluation of high density lipoprotein from mouse small intestine by an in situ perfusion technique[S]

Journal of Lipid Research, 2014
The small intestine (SI) is the second-greatest source of HDL in mice. However, the selective evaluation of SI-derived HDL (SI-HDL) has been difficult because even the origin of HDL obtained in vivo from the intestinal lymph duct of anesthetized rodents ...

Synthetic Perfusion Maps: Imaging Perfusion Deficits in DSC-MRI with Deep Learning [PDF]

arXiv, 2018
In this work, we present a novel convolutional neural net- work based method for perfusion map generation in dynamic suscepti- bility contrast-enhanced perfusion imaging. The proposed architecture is trained end-to-end and solely relies on raw perfusion data for inference. We used a dataset of 151 acute ischemic stroke cases for evaluation.
