PIEZO Force Sensing in Vascular Biology: An Explosion of New Knowledge, Concepts and Opportunity

Advanced Science, EarlyView.
Knowledge of the remarkable mechanical force sensing and electrically transducing PIEZO1 and PIEZO2 channels is discussed across vascular biology and its cell types from the embryonic to adult stages in health, disease and old age. How the channels work, relate to other factors and signal for tissue responses to mechanical forces is debated.

Ausencia de la vena cava superior derecha y persistencia de la vena cava superior izquierda en el feto: Presentación de dos casos.

Revista Cubana de Cardiología y Cirugía Cardiovascular, 2011
Objetivo: La Vena Cava Superior Izquierda Persistente es la anomalía vascular congénita más frecuente. En la gran mayoría de las ocasiones la persistencia de la misma coincide con la presencia de la vena cava superior derecha.

Type‐I Heterostructure CdZnS/ZnS Core/Shell Quantum Dots Scintillators for Stable, High‐Resolution, and Real‐Time X‐Ray Imaging

Advanced Science, EarlyView.
Ultra‐bright Cd0.27Zn0.73S/7 ML‐ZnS core/shell quantum dots exhibit a photoluminescence quantum yield exceeding 96% and a fourfold enhancement in radioluminescence intensity compared to CsPbBr3. Variable‐temperature photophysical analysis reveals that the narrowband emission originates from direct recombination of edge excitons.

Parametric Design of Continuum Robots Using Interlocking Ball Joints

Advanced Intelligent Systems, EarlyView.
Herein, a parametric design methodology is introduced for producing a wide variety of modular ball joint‐based continuum robots. It is demonstrate by designing a magnetically actuated continuum robot for cardiac ablations. The methodology is released as an open‐source computer‐assisted design extension that automatically designs continuum robots based ...

Absence of right superior vena cava and persistence of left superior vena cava in fetus: Presenting two cases.

Revista Cubana de Cardiología y Cirugía Cardiovascular, 2011
Persistent Left Superior Vena Cava is the most common congenital vascular anomaly. In the vast majority of cases its persistence coincides with thepresence of the right superior vena cava. The absence of the latter with persistent left superior vena cava

Management of Cardiovascular Health Issues in Turner Syndrome: Expert Insights and Expanded Recommendations From the 2024 Guideline Development Team

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Turner syndrome (TS) is frequently complicated by congenital heart disease (CHD). While left‐sided lesions such as bicuspid aortic valve (BAV) and coarctation of the aorta are the most common structural heart lesions in TS, other anomalies, such as aortic arch malformations, hypoplastic left heart syndrome (HLHS), persistent left superior vena

The Impact of Karyotype on Congenital Heart Diseases in Turner Syndrome: A Systematic Review and Meta‐Analysis

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT It is evident that Turner syndrome (TS) impacts almost all developmental stages of the fetal heart with congenital heart disease (CHD) being seen in 23%–50% of individuals. Although the spectrum of CHDs in TS is well‐established, with left‐sided lesions predominating, the influence of specific karyotypes on the prevalence and types of CHDs ...

Transcatheter Management of Severe Paravalvular Leak in the Inferior Vena Cava Prosthesis of the TricValve Bicaval Valve System

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We present a 74‐year‐old female with a history of mechanical aortic and mitral valve implantation and non‐Hodgkin lymphoma. She presented with right sided heart failure due to severe functional tricuspid regurgitation and was treated with transcatheter TricValve bicaval system implantation.
