Quantitative Confounder Analysis of Electrocardiogram Signals in Cardiac Magnetic Resonance at 1.5, 3 and 7 T—Assessing Standardized Electrode Positions and Sequence Types—Towards Quality Assurance

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The electrocardiogram (ECG) used for gating in cardiac MRI may be compromised by multiple confounders inside the scanner bore. Purpose To quantify the influence of magnetic field strengths (1.5 T/3 T/7 T), standardized electrode positions, and imaging sequences on ECG signals used for gating. Study Type Prospective.

Age‐Dependent Correlation of Pulmonary Function Impairment and Aortic Arch Stiffness in Mice

open access: yesPediatric Discovery, EarlyView.
This study examined the relationship between aortic arch stiffness and lung function in aging mice. Multiple linear regression modeling showed moderate to strong correlations between the rise in aortic arch stiffness and changes in lung function as the mice progressively aged.

Techniques for Identification of Left Ventricular Asynchrony for Cardiac Resynchronization Therapy in Heart Failure [PDF]

open access: yes, 2005
The most recent treatment option of medically refractory heart failure includes cardiac resynchronization therapy (CRT) by biventricular pacing in selected patients in NYHA functional class III or IV heart failure. The widely used marker to indicate left

Assessment of Double Outlet Left Ventricle in Pediatrics Using Transthoracic Echocardiography and Computed Tomographic Angiography

open access: yesPediatric Discovery, EarlyView.
The clinical manifestation of DOLV was atypical. TTE has a relatively high diagnostic accuracy for DOLV in pediatric, which is very valuable for its early detection. ABSTRACT Double outlet left ventricle (DOLV) is a rare congenital cardiac anomaly in which both great arteries originate entirely or predominantly from the morphologic left ventricle.

Proteomic Biomarkers Are Linked to QTc Interval in Patients With Chronic Heart Failure

open access: yesPROTEOMICS – Clinical Applications, EarlyView.
ABSTRACT Objective This study investigates the link between circulating proteins and rate‐corrected QT (QTc) interval in patients with heart failure with reduced ejection fraction (HFrEF) and their association with cardiovascular outcomes. Methods and Results We analyzed 197 HFrEF patients from the prospective Serial Biomarker Measurements and New ...

Layer‐by‐Layer Assembly of Plant Viruses Utilizing Specific Binding

open access: yesphysica status solidi (a), EarlyView.
A bilayer of the tomato bushy stunt virus (TBSV) is constructed layer‐by‐layer by utilizing the specific interaction between Strep‐Tactin (an engineered type of streptavidin) and modified TBSV with Strep‐Tag II (an engineered type of biotin) side chains. A layer coverage above 84% could be achieved.
