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

Pediatric 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.

Breaking the Low Concentration Barrier of Single‐Molecule Fluorescence Quantification to the Sub‐Picomolar Range

Small Methods, EarlyView.
Single‐molecule fluorescence detection can become highly challenging for diluted concentrations in the picomolar range. This “low concentration barrier” is broken into and achieves quantitative detection down to 0.1 pM. Introducing a diaphragm into a standard confocal microscope and implementing fluorescence lifetime correlation spectroscopy (FLCS ...

Structural behavior of deteriorated Gerber half‐joints in highway overpasses by nonlinear finite element analysis combined with a simplified uniform‐corrosion model

Structural Concrete, EarlyView.
Abstract Gerber half‐joints, broadly used in the last century as elements of concrete bridges, are prone to corrosion‐induced deterioration, which may lead to brittle shear collapse. It is of paramount importance to develop advanced numerical models for simulating the collapse behavior of Gerber half‐joints, taking material deterioration into account ...

Detection of corrosion effects on prestressed concrete bridge deck slabs from the champlain bridge through non‐destructive testing techniques

Structural Concrete, EarlyView.
Abstract As aging infrastructures raise public concerns, evaluating their performance is crucial for maintaining structural integrity, especially for corroding prestressed concrete members. These structures may experience substantial tendon cross‐sectional area loss before any visible deterioration becomes detectable.

European Consensus on Functional Bloating and Abdominal Distension—An ESNM/UEG Recommendations for Clinical Management

United European Gastroenterology Journal, EarlyView.
ABSTRACT Introduction Abdominal distension is an objective visible sign of increased abdominal girth. Bloating is a feeling of abdominal fullness and discomfort. Bloating may be associated or not with abdominal distension. Bloating and abdominal distension are among the most commonly reported gastrointestinal symptoms and may be associated with both ...

OXPHOS complex deficiency in congenital myopathy: A systematic review

European Journal of Clinical Investigation, EarlyView.
This systematic review assessed oxidative phosphorylation (OXPHOS) complex dysfunction in genetically confirmed congenital myopathies (CM). Among 5841 studies screened, 23 publications, comprising 45 CM cases, met the inclusion criteria. OXPHOS dysfunction was identified in 78% of cases, particularly where enzymology was performed, with RYR1 most ...
