Reopening after successful coil occlusion for patent ductus arteriosus.
OBJECTIVES This study was performed to determine the frequency of patent ductus arteriosus (PDA) reopening and the factors that may predict reopening after successful coil occlusion. BACKGROUND Transcatheter coil occlusion is a widely used and accepted method to close a PDA. After documented successful coil occlusion, we found PDAs that reopened. We hypothesized that specific factors are invo...
متن کاملThe Decidability of -Pushing PDA
Sénizergues has proved that language equivalence is decidable for disjoint -deterministic PDA. Stirling has showed that strong bisimilarity is decidable for PDA. On the negative side Srba demonstrated that the weak bisimilarity is undecidable for normed PDA. Later Jančar and Srba established the undecidability of the weak bisimilarity for disjoint -pushing PDA and disjoint -popping PDA. In the ...
متن کاملHair dye-incorporated poly-γ-glutamic acid/glycol chitosan nanoparticles based on ion-complex formation
BACKGROUND p-Phenylenediamine (PDA) or its related chemicals are used more extensively than oxidative hair dyes. However, permanent hair dyes such as PDA are known to have potent contact allergy reactions in humans, and severe allergic reactions are problematic. METHODS PDA-incorporated nanoparticles were prepared based on ion-complex formation between the cationic groups of PDA and the anion...
متن کاملCalcium-Mediated Control of Polydopamine Film Oxidation and Iron Chelation
The facile preparation of conformal polydopamine (PDA) films on broad classes of materials has prompted extensive research into a wide variety of potential applications for PDA. The constituent molecular species in PDA exhibit diverse chemical moieties, and therefore highly variable properties of PDA-based devices may evolve with post-processing conditions. Here we report the use of redox-inact...
متن کاملEtiology of patent ductus arteriosus in dogs.
Patent ductus arteriosus (PDA) is the most common congenital heart disease in dogs and usually causes heart failure and death unless corrected at a young age. Previous histologic studies in a line of dogs derived from Miniature Poodles with hereditary PDA identified varying degrees of hypoplasia and asymmetry of ductus-specific smooth muscle and the presence of aortalike elastic tissue in the d...
متن کاملOn probabilistic pushdown automata
We study the most important probabilistic computation modes for pushdown automata. First we show that deterministic pushdown automata (pda) are weaker than Las Vegas pda, which in turn are weaker than one-sided-error pda. Next one-sidederror pda are shown to be weaker than (nondeterministic) pda. Finally bounded error two-sided error pda and nondeterministic pda are incomparable. To show the li...
