Abnormal calcium homeostasis in heart failure with preserved ejection fraction is related to both reduced contractile function and incomplete relaxation: An electromechanically detailed biophysical modelling study

Frontiers in Physiology, 2015
Heart failure with preserved ejection fraction (HFpEF) accounts for about 50% of heart failure cases. It has features of incomplete relaxation and increased stiffness of the left ventricle.

Instantaneous Pressure‐Volume Relationships and Their Ratio in the Excised, Supported Canine Left Ventricle

Circulation Research, 1974
We have previously shown in the normally ejecting canine left ventricle that E(t), the time-varying ratio of instantaneous pressure, P(t), to instantaneous volume, V(t), is little affected by end-diastolic volume or aortic pressure.

Robust Systemic and Mucosal Immune Responses to Coxsackievirus B3 Elicited by Spider Silk Protein Based Nanovaccines via Subcutaneous Immunization

Advanced Functional Materials, EarlyView.
Spider minor ampullate silk protein (MiSp) and retinoic acid (RA) based nanovaccine are capable of eliciting both mucosal and systemic immune responses following subcutaneous administration and demonstrate significant protective effects against CVB3 infection in mice.

Endomysium in left ventricle [PDF]

Heart, 2001
This image shows the three dimensional arrangement of endomysial collagen fibres in the left ventricle free wall. The endomysium was studied by means of scanning electron microscopy after sodium hydroxide maceration in rabbit non-contracted heart. This method of maceration allowed the isolation of collagen fibres, …

Time‐Controlled Dual Targeting to Program Systemic and Intercellular Transfer of Therapeutic Effects

Advanced Functional Materials, EarlyView.
Aspirin‐liposomes loaded onto monocytes enable inflammation‐triggered targeting and efficient hand‐over of aspirin to inflamed cells. Monocytes uptake a significant portion of aspirin‐liposomes, prolonging therapeutic action. This approach enhances anti‐inflammatory effects through intercellular transfer, demonstrating a translational strategy for ...

Zebrafish as a Model System for Brugada Syndrome

Reviews in Cardiovascular Medicine
Brugada syndrome (BrS) is an inheritable cardiac arrhythmogenic disease, associated with an increased risk of sudden cardiac death. It is most common in males around the age of 40 and the prevalence is higher in Asia than in Europe and the United States.

Segmentation of brain magnetic resonance images based on multi-atlas likelihood fusion: testing using data with a broad range of anatomical and photometric profiles

Frontiers in Neuroscience, 2015
We propose a hierarchical pipeline for skull-stripping and segmentation of anatomical structures of interest from T1-weighted images of the human brain. The pipeline is constructed based on a two-level Bayesian parameter estimation algorithm called multi-

Where is the right ventricle?

BMJ Case Reports, 2014
A 20-year-old man with no history of known cardiac disease was admitted with dyspnoea on exertion during a few weeks. His effort capacity was class I. At physical examination, his blood pressure was 120/70 mm Hg and pulse 80 bpm. His physical examination

Left Ventricle Segmentation in Cardiac MR Images Using Fully Convolutional Network [PDF]

arXiv, 2018
Medical image analysis, especially segmenting a specific organ, has an important role in developing clinical decision support systems. In cardiac magnetic resonance (MR) imaging, segmenting the left and right ventricles helps physicians diagnose different heart abnormalities.
