BACKGROUND Bedside diagnosis of patent ductus arteriosus (PDA) continues to be important, especially when echocardiography is not readily available. OBJECTIVE The aim of our study was to evaluate whether measurement of left main bronchus displacement portrayed on a chest X-ray as a widened carina angle (CA) may support the presumptive diagnosis of PDA. METHODS Displacement of the left bronc...

Contrast echocardiography is a safe and accurate method of diagnosing patent ductus arteriosus (PDA) in newborn infants. In this study the presence of PDA in very low birthweight infants receiving mechanical ventilation was investigated by contrast echocardiography. This was used as a basis for determining the accuracy of clinical signs and M mode echocardiography in the diagnosis of PDA. At th...

Mussels have been shown to attach to virtually all types of inorganic and organic surfaces via their adhesive proteins. The adhesive proteins secreted by mussels contain high concentrations of catechol and amine functional groups, which have similar functional groups with polydopamine (PDA). Inspired by mussels, a mild and environmentally friendly method was used to synthesize Ag nanoparticles ...

Patients affected by panic disorder with agoraphobia (PDA) often suffer from visuo-spatial disturbances. In the present study, we tested the place-learning abilities in a sample of 31 PDA patients compared to 31 healthy controls (CTR) using the computer-generated arena (C-G Arena), a desktop-based computer program developed at the University of Arizona (Jacobs et al 1997, for further detail abo...

From this systematic literature review it was concluded that panic disorder with agoraphobia (PDA) can sometimes occur in conjunction with marital problems. Couples-based treatments for PDA – partner-assisted exposure and marital therapy – can be an effective treatment for the condition. It is as effective as individually based cognitive behaviour therapy. Involving partners of people with PDA ...

We introduce good-for-games $\omega$-pushdown automata ($\omega$-GFG-PDA). These are whose nondeterminism can be resolved based on the input processed so far. Good-for-gameness enables to composed with games, trees, and other automata, applications which otherwise require deterministic automata. Our main results that $\omega$-GFG-PDA more expressive than $\omega$- pushdown solving infinite game...

Abstract In this work, mussel-inspired surface functionalization of halloysite nanotubes (HNTs) were coated by in situ self-polymerization polydopamine (PDA) to synthesize core-shell structural composites (HNTs@PDA), and then incorporated into polyarylene ether nitrile (PEN) matrix. Due the strong adhesion PDA modification layer formation hydrogen bonds between polar group PEN catechol PDA, dis...

Further studies of hereditary patent ductus arteriosus (PDA) in the dog show the defect to have a graded phenotypic expression. A high proportion of offspring of test matings had a fully patent ductus arteriosus, while a smaller proportion had a blind diverticulum of the ductus arteriosus which communicated with the aorta. This is considered to be a forme fruste of PDA, representing incomplete ...

Patients with pancreatic ductal adenocarcinoma (PDA) typically succumb to mortality early, even following surgical resection. Therefore, prognostic factors associated with early mortality are required to improve the survival of patients with PDA following surgical resection. Carbohydrate sulfotransferase 15 (CHST15) is responsible for the biosynthesis of sulfated chondroitin sulfate E (CS-E), w...

OBJECTIVE The persistence of the patent ductus arteriosus (PDA) is frequently encountered in very preterm infants. Neither preventive nor curative treatments of PDA have been shown to improve the outcome of these infants. Since no consensus on optimal treatment of PDA is established, we evaluated the rate of spontaneous PDA closure in infants born before 28 weeks of gestation. PATIENTS AND ME...
