Anticoagulation for Mechanical Heart Valves: Will Oral Factor Xa Inhibitors Be Effective?

open access: yesArteriosclerosis, Thrombosis and Vascular Biology, 2017
The global burden of valvular heart disease, which currently affects more than 100 million people, is growing with the aging population.1 Severe valvular heart disease is associated with major morbidity and mortality and often necessitates surgical valve

Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics

open access: yes, 2018
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for severe valvular disease.

Observation of non-Markovian micro-mechanical Brownian motion [PDF]

open access: yes, 2015
All physical systems are to some extent open and interacting with their environment. This insight, basic as it may seem, gives rise to the necessity of protecting quantum systems from decoherence in quantum technologies and is at the heart of the ...

Teardrop and heart orbits of a swinging Atwood's Machine

open access: yes, 1993
An exact solution is presented for a swinging Atwood's machine. This teardrop-heart orbit is constructed using Hamilton-Jacobi theory. The example nicely illustrates the utility of the Hamilton-Jacobi method for finding solutions to nonlinear mechanical ...

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Relationship between fibre orientation and tensile strength of natural collagen membranes for heart valve leaflets [PDF]

open access: yes, 2011
Heart valve prostheses are used to replace native heart valves which that are damaged because of congenital diseases or due to ageing. Biological prostheses made of bovine pericardium are similar to native valves and do not require any anticoagulation ...

The effectiveness of the cardiac resynchronization in a patient with ischemic cardiomyopathy [PDF]

open access: yes, 2018
Cardiac resynchronization therapy (CRT) in multiple and large trials has been demonstrated to improve symptoms and decrease hospitalization and mortality of patients when used in addition to optimal medical therapy.

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
