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...

We report a novel and sensitive amperometric sensor for chlorpromazine (CPZ) based on reduced graphene oxide (RGO) and polydopamine (PDA) composite modified glassy carbon electrode. The RGO@PDA composite was prepared by electrochemical reduction of graphene oxide (GO) with PDA. The RGO@PDA composite modified electrode shows an excellent electro-oxidation behavior to CPZ when compared with other...

Patent ductus arteriosus (PDA) is a rare clinical finding in adult patients. Considering the increase in cases of PDA discovered incidentally on echocardiograms at young ages, and the life-shortening effect of PDA, it is rare to diagnose PDA in old patients. We report a case of an 80-year-old patient who experienced symptoms of congestive heart failure showed findings suggestive of PDA in echoc...
