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

arXiv, 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 ...

Comments on Unstable Branes [PDF]

JHEP 0102 (2001) 023, 2000
We argue that type II string theories contain unstable NS4 branes, which descend from a conjectured unstable M4 brane of M-theory. Assuming that an M2 brane can arise in M5 brane/anti-brane annihilation, the unstable M4 brane, and also an unstable M3 brane, must exist as sphalerons.

Morphology of the sternoclavicular joint and its microanatomical changes in response to osteoarthritic degeneration

Clinical Anatomy, EarlyView.
Abstract Although the sternoclavicular joint shares structural similarities with the knee and hip joints as a diarthrodial joint, its biomechanics differ significantly due to its non‐weight‐bearing nature. Nevertheless, it is subject to considerable loading, leading to increased susceptibility to osteoarthritis, a prevalent condition characterized by ...

A European update on transcatheter aortic valve implantation (TAVI) in the COVID era

Journal of Anatomy, Volume 242, Issue 1, Page 50-63, January 2023., 2023
A timely review of key Transcatheter Aortic Valve Implantation (TAVI) device trials delineated by surgical risk. Abstract Minimally invasive approaches for aortic valve replacement are now at the forefront of pathological aortic valve treatment. New trials show comparability of these devices to existing therapies, not only in high‐risk surgical cohorts

Novel Classification of Ischemic Heart Disease Using Artificial Neural Network [PDF]

Computing in Cardiology 2020, 2020
Ischemic heart disease (IHD), particularly in its chronic stable form, is a subtle pathology due to its silent behavior before developing in unstable angina, myocardial infarction or sudden cardiac death. Machine learning techniques applied to parameters extracted form heart rate variability (HRV) signal seem to be a valuable support in the early ...

Comparison of the prevalence of enteroviruses in blood samples of patients with and without unstable angina

ARYA Atherosclerosis, 2017
BACKGROUND: Although the role of enteroviruses has been proved in heart diseases, extensive information is not available on the association between enteroviruses and unstable angina.

Reduced plasma adiponectin levels relative to oxidized low density lipoprotein and nitric oxide in coronary artery disease patients

Clinics, 2011
INTRODUCTION: Adiponectin is a circulating hormone that is produced exclusively by adipocytes and has antiinflammatory and anti-atherogenic properties. The hypothesis that there are differences in adiponectin levels between stable and unstable coronary ...

Automated Diagnosis of Cardiovascular Diseases from Cardiac Magnetic Resonance Imaging Using Deep Learning Models: A Review [PDF]

arXiv, 2022
In recent years, cardiovascular diseases (CVDs) have become one of the leading causes of mortality globally. CVDs appear with minor symptoms and progressively get worse. The majority of people experience symptoms such as exhaustion, shortness of breath, ankle swelling, fluid retention, and other symptoms when starting CVD. Coronary artery disease (CAD),
