Double‐Sided Conformable Piezoelectric Force Sensor with Enhanced Performance and Bending Correction

Advanced Electronic Materials, EarlyView.
This work addresses the challenge of measuring low forces on soft surfaces. An innovative conformable piezoelectric force sensor is presented. The use of a highly flexible TPU substrate enables a tenfold increase in the sensor's sensitivity to compression while a double‐sided structure prevents the signal from being disturbed by bending due to ...

Phenotypic Expansion of Knobloch Syndrome Type 2 in an Individual With a De Novo PAK2 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT P21‐activated kinase 2 (PAK2) is a serine/threonine kinase essential for a variety of cellular processes including signal transduction, cellular survival, proliferation, and migration. A recent report proposed monoallelic PAK2 variants cause Knobloch syndrome type 2 (KNO2)—a developmental disorder primarily characterized by ocular anomalies ...

Disruption of the blood–brain barrier contributes to neurobehavioral changes observed in rheumatic heart disease

Animal Models and Experimental Medicine, EarlyView.
Sydenham's chorea (SC) is the neurological manifestation associated with acute rheumatic fever (ARF), triggered by a group A streptococcal (GAS) infection. Anti‐GAS antibodies cross‐reacting with tissue proteins are implicated in the development of neurological changes. In this study, using an animal model, we demonstrate that a compromised blood–brain

Automatic Time‐Resolved Cardiovascular Segmentation of 4D Flow MRI Using Deep Learning

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 191-203, January 2023., 2023
Background Segmenting the whole heart over the cardiac cycle in 4D flow MRI is a challenging and time‐consuming process, as there is considerable motion and limited contrast between blood and tissue. Purpose To develop and evaluate a deep learning‐based segmentation method to automatically segment the cardiac chambers and great thoracic vessels from 4D

Anticoagulation intensity and outcomes among southeast‐Asians with moderate‐to‐severe mitral valve stenosis

British Journal of Clinical Pharmacology, EarlyView.
Objective To determine the optimal anticoagulation intensity of warfarin in a South‐East Asian population with moderate‐to‐severe rheumatic mitral stenosis. Methods A multicentre, retrospective study examined patients with rheumatic mitral stenosis who had not undergone valve replacement or repair and required long‐term warfarin therapy at two ...

Mitral annulus morphologic and functional analysis using real time tridimensional echocardiography in patients submitted to unsupported mitral valve repair

Brazilian Journal of Cardiovascular Surgery, 2015
Introduction:Mitral valve repair is the treatment of choice to correct mitral insufficiency, although the literature related to mitral valve annulus behavior after mitral repair without use of prosthetic rings is scarce.Objective:To analyze mitral ...
