Uncertainty quantification of a three-dimensional in-stent restenosis model with surrogate modelling [PDF]

open access: yesarXiv, 2021
In-Stent Restenosis is a recurrence of coronary artery narrowing due to vascular injury caused by balloon dilation and stent placement. It may lead to the relapse of angina symptoms or to an acute coronary syndrome. An uncertainty quantification of a model for In-Stent Restenosis with four uncertain parameters (endothelium regeneration time, the ...

The Myogenic Response in Isolated Rat Cerebrovascular Arteries: Smooth Muscle Cell Model [PDF]

open access: yesMedical Engineering & Physics, 25(8):691-709, 2003, 2013
Previous models of the cerebrovascular smooth muscle cell have not addressed the interaction between the electrical, chemical and mechanical components of cell function during the development of active tension. These models are primarily electrical, biochemical or mechanical in their orientation, and do not permit a full exploration of how the smooth ...

BRG1 expression is increased in thoracic aortic aneurysms and regulates proliferation and apoptosis of vascular smooth muscle cells through the long non-coding RNA HIF1A-AS1 in vitro.

open access: yesEuropean Journal of Cardio-Thoracic Surgery, 2015
OBJECTIVES Brahma-related gene 1 (BRG1) and long non-coding RNAs (lncRNAs) play important roles in cellular processes. However, little is known regarding their roles in thoracic aortic aneurysms.

Genomics‐led approach to drug testing in models of undifferentiated pleomorphic sarcoma

open access: yesMolecular Oncology, EarlyView.
GA text Genomic data from undifferentiated pleomorphic sarcoma patients and preclinical models were used to inform a targeted drug screen. Selected compounds were tested in 2D and 3D cultures of UPS cell lines. A combination of trametinib and infigratinib was synergistic in the majority of UPS cell lines tested, which was further confirmed in an ex ...

Blocking PERK resuces vascular smooth muscle cells from homocysteine-induced ER stress and apoptosis

open access: yesFrontiers in Bioscience-Landmark, 2020
Hyperhomocysteinemia induces stress response in endoplasmic reticulum (ERS). Here, we tested whether blockage of homocysteine (Hcy) induced ERS and subsequent apoptosis in vascular smooth muscle cells can be inhibited by blockage of PERK/eIF2α/ATF4/CHOP ...

Acute oxygen sensing by vascular smooth muscle cells

open access: yesFrontiers in Physiology, 2023
An adequate supply of oxygen (O2) is essential for most life forms on earth, making the delivery of appropriate levels of O2 to tissues a fundamental physiological challenge.

A control mechanism for intramural periarterial drainage via astrocytes: How neuronal activity could improve waste clearance from the brain [PDF]

open access: yes, 2017
The mechanisms behind waste clearance from deep within the parenchyma of the brain remain unclear to this date. Experimental evidence has shown that one pathway for waste clearance, termed intramural periarterial drainage (IPAD), is the rapid drainage of interstitial fluid (ISF) via basement membranes (BM) of the smooth muscle cells (SMC) of cerebral ...

Patient-specific predictions of aneurysm growth and remodeling in the ascending thoracic aorta using the homogenized constrained mixture model [PDF]

open access: yesBiomechanics and Modeling in Mechanobiology, Springer Verlag, 2019, 18 (6), pp.1895-1913, 2019
In its permanent quest of mechanobiological homeostasis, our vascula-ture significantly adapts across multiple length and time scales in various physiological and pathological conditions. Computational modeling of vascular growth and remodeling (G\&R) has significantly improved our insights of the mechanobio-logical processes of diseases such as ...

MicroRNA-34a Induces Vascular Smooth Muscle Cells Senescence by SIRT1 Downregulation and Promotes the Expression of Age-Associated Pro-inflammatory Secretory Factors.

open access: yesThe journals of gerontology. Series A, Biological sciences and medical sciences, 2015
Arterial aging is a major risk factor for the occurrence of cardiovascular diseases. The aged artery is characterized by endothelial dysfunction and vascular smooth muscle cells altered physiology together with low-grade chronic inflammation.

Vascular Smooth Muscle Cell Proliferation in Restenosis [PDF]

open access: yesCirculation: Cardiovascular Interventions, 2011
Current therapeutic approaches to restore blood flow in stenotic blood vessels involve the use of percutaneous devices and coronary bypass surgery. In all procedures that disrupt the normal integrity of the blood vessels, there is an increased incidence of vessel luminal narrowing, termed restenosis.
