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...
Polydiacetylene (PDA) compound has unique chromatic properties when embedded in methylcellulose base. Therefore, this could be used as intelligent packaging. PDA exhibits blue-to-red color transition under certain stimuli, which was caused by alterations in PDA conjugation length backbone. For a specific color modification, bio-recognition tools were covalently linked with PDA. In this work, a ...
In the preceding article, we investigated the spatial properties of the induction of the prolonged depolarizing afterpotential (PDA) by shifting visual pigment from the rhodopsin (R) to the metarhodopsin (M) state in the barnacle photoreceptor. In this work, we have studied the ranges within the cell of the antagonistic effects on the PDA of M-to-R transfer. When this transfer occurs during a P...
BACKGROUND AND OBJECTIVES This study's objective was to evaluate the acceptability, effect, and use of handheld computers (also known as personal digital assistants or PDAs) as a reward for undergraduate rural community-based family medicine preceptors. METHODS All rural, undergraduate family physician teachers who accepted an undergraduate student for a 1-month placement were offered the cho...
