Extensions of weak matroids over skew tracts and strong matroids over stringent skew hyperfields [PDF]

arXiv, 2020
Matroids over skew tracts provide an algebraic framework simultaneously generalizing the notions of linear subspaces, matroids, oriented matroids, phased matroids, and some other "matroids with extra structure". A single-element extension of a matroid $\mathcal{M}$ over a skew tract $T$ is a matroid $\widetilde{\mathcal{M}}$ over $T$ obtained from ...

Lineage labeling with zebrafish hand2 Cre and CreERT2 recombinase CRISPR knock‐ins

Developmental Dynamics, EarlyView.
Abstract Background The ability to generate endogenous Cre recombinase drivers using CRISPR‐Cas9 knock‐in technology allows lineage tracing, cell type‐specific gene studies, and in vivo validation of inferred developmental trajectories from phenotypic and gene expression analyses. This report describes endogenous zebrafish hand2 Cre and CreERT2 drivers

Trametinib alters contractility of paediatric Noonan syndrome‐associated hypertrophic myocardial tissue slices

ESC Heart Failure, EarlyView.
Abstract Aims No curative treatment is available for RASopathy‐associated childhood‐onset hypertrophic cardiomyopathy (RAS‐CM). Preclinical data and individual reports suggest a beneficial effect of small molecules targeting the RAS–mitogen‐activated protein (MAP) kinase (MAPK) pathway in severely affected RAS‐CM patients.

Prognostic value of physical activity, gender, and age versus ECG in localizing the idiopathic ventricular outflow tract arrhythmias [PDF]

Balneo and PRM Research Journal
Background: The idiopathic ventricular outflow tract arrhythmias may arise either from the right ventricular outflow tract or the left ventricular outflow tract.

Severe Left Ventricular Outflow Tract Obstruction Immediately After Surgical Repair of Ebstein’s Anomaly

JACC: Case Reports, 2020
A 52-year-old man following surgery for Ebstein’s anomaly after repair developed acute hemodynamically significant left ventricular outflow tract obstruction with systolic anterior motion of the mitral valve and severe mitral regurgitation.

Predicting right ventricular failure after left ventricular assist device implant: A novel approach

ESC Heart Failure, EarlyView.
Abstract Aims Right ventricular (RV) failure (RVF) after left ventricular assist device (LVAD) implant is an important cause of morbidity and mortality. Modern, data‐driven approaches for defining and predicting RVF have been under‐utilized. Methods Two hundred thirty‐two patients were identified with a mean age of 55 years; 40 (17%) were women, 132 ...

The Fate of the Outflow Tract Septal Complex in Relation to the Classification of Ventricular Septal Defects

Journal of Cardiovascular Development and Disease, 2019
It is now established that the entity often described as an “aortopulmonary septal complex„ is better considered as an “outflow tract septal complex„.

Slow escape in tracts [PDF]

arXiv, 2018
Let $f$ be a transcendental entire function. By a result of Rippon and Stallard, there exist points whose orbit escapes arbitrarily slowly. By using a range of techniques to prove new covering results, we extend their theorem to prove the existence of points which escape arbitrarily slowly within logarithmic tracts and tracts with certain boundary ...

Early genetic screening and cardiac intervention in patients with cardiomyopathies in a multidisciplinary clinic

ESC Heart Failure, EarlyView.
Abstract Aims Patients with cardiomyopathies are a heterogeneous group of patients who experience high morbidity and mortality. Early cardiac assessment and intervention with access to genetic counselling in a multidisciplinary Cardiomyopathy Clinic may improve outcomes and prevent progression to advanced heart failure.
