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...

BACKGROUND The optimal treatment regimen or protocol for managing a persistent patent ductus arteriosus (PDA) in extremely low birth weight (ELBW) infants has not been well established. This study was aimed at evaluating the failure rate of a cyclooxygenase (COX) inhibitor (COI) for PDA closure and to determine the incidence of a PDA requiring ligation in ELBW infants. We examined the clinical ...

The aggressiveness of pancreatic ductal adenocarcinoma (PDA) is characterized by its high metastatic potential and lack of effective therapies, which is the result of a lack of understanding of the mechanisms involved in promoting PDA metastases. We identified Annexin A2 (ANXA2), a member of the Annexin family of calcium-dependent phospholipid binding proteins, as a new molecule that promotes P...

Sénizergues has proved that language equivalence is decidable for disjoint ǫ-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 ǫ-pushing PDA and disjoint ǫ-popping PDA. Thes...

In the title coordination polymer, [Ce(2)(C(10)H(8)O(4))(3)(H(2)O)(2)](n), each Ce(III) atom is nine-coordinated by eight O atoms from six different 1,3-phenyl-enediacetate (pda) bivalent anions and one O atom from a coordinated water mol-ecule, forming a distorted tricapped trigonal-prismatic coordination geometry. Eight Ce(III) ions and twelve pda ligands form a large [Ce(8)(pda)(12)] ring, a...

Their small size and ease of use makes Personal Digital Assistants (PDAs) very attractive for inclusion as clients in mobile multimedia applications. Alas, the cost for integration of PDA in distributed multimedia systems is high, as the resource limitations on PDA require client adaptation, and as software development on PDA is comparatively expensive. We present PocketWeb, a tool facilitating...

Patent ductus arteriosus (PDA) is sometimes undetected until adulthood, and surgical closure of a PDA is dangerous because of the calcification of the ductus. Percutaneous approaches such as coil embolization and use of a PDA occluder are less invasive; however, these devices are not suitable for PDA with thoracic aortic aneurysm (TAA). We present the case of a 72-year-old female patient who un...

PURPOSE Pancreatic ductal adenocarcinoma (PDA) cells are known to produce excessive amounts of reactive oxygen species (ROS), particularly superoxide, which may contribute to the aggressive and refractory nature of this disease. Extracellular superoxide dismutase (EcSOD) is an antioxidant enzyme that catalyzes the dismutation of superoxide in the extracellular environment. This study tests the ...

OBJECTIVES Comparison of effectiveness and cost of transcatheter occlusion of patent ductus arteriosus (PDA) with surgical ligation of PDA. METHODS This retrospective comparative study was conducted in the pediatric cardiology department of Ch. Pervaiz Elahi Institute of Cardiology Multan, Pakistan. Data of 250 patients who underwent patent ductus arteriosus (PDA) closure either surgical or t...
