Marburg Virus Glycoprotein Is a Remarkable Virulent Factor Linked to Hemorrhagic Pathology: Evidence from Multimodal Experimental Systems

open access: yesAdvanced Science, EarlyView.
By integrating data from in vitro, ex vivo, and in vivo models, our research identifies the MARV glycoprotein as a remarkable hemorrhagic factor, filling a major gap in this important field. It also provides practical experimental tools for the basic research on viral pathogenesis and applied research aimed at antiviral intervention for hemorrhagic ...

Iterative Segmentation from Limited Training Data: Applications to Congenital Heart Disease

open access: yes, 2018
We propose a new iterative segmentation model which can be accurately learned from a small dataset. A common approach is to train a model to directly segment an image, requiring a large collection of manually annotated images to capture the anatomical ...

Conformable Microelectrode Arrays Integrated with a Scoop‐Shaped Slide‐Well for Dynamic Electrophysiological Profiling of Patient‐Derived Cardiac Organoids

open access: yesAdvanced Science, EarlyView.
A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.

Palliative surgery for single ventricle heart malformations.

open access: yesInternational surgery, 1983
During a 6-year period, 24 patients, aged 7 days to 18 years, underwent palliative surgery for single-ventricle heart malformations; 22 has single-left ventricle with outlet chamber (14 with L-transposition); only two had type C malformation (van Praagh).

Neuid: A Novel Neuron‐Enriched LncRNA that Connects Epigenetic Gene Silencing to Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT The increasing evidence that non‐coding RNAs can become deregulated during pathogenesis is dramatically expanding the space for drug discovery beyond the protein‐coding genome. Long noncoding RNAs (lncRNAs) are emerging as key regulators of cellular function, yet most remain uncharacterized.

Cardiac magnetic resonance imaging in Holmes’ heart: Decoding a rare variant of double-inlet left ventricle

open access: yesAnnals of Pediatric Cardiology
Holmes’ heart, a rare variant of double-inlet left ventricle with rudimentary right ventricle and ventriculoarterial concordance, predisposes to pulmonary overcirculation and heart failure due to unrestricted shunting. We report the case of a 32-year-old

Application of NASTRAN for stress analysis of left ventricle of the heart [PDF]

open access: yes, 1975
Knowing the stress and strain distributions in the left ventricular wall of the heart is a prerequisite for the determination of the muscle elasticity and contractility in the process of assessing the functional status of the heart.
