Persistent ductus arteriosus (PDA) complicated the clinical course in 45 (15%) of 299 babies with the respiratory distress syndrome (RDS) presenting over a 3-year period. The incidence of PDA complicating RDS rose with decreasing birthweight and was highest in babies with severe RDS as judged by the use of assisted ventilation. In babies with a birthweight of less than 1500 g, PDA occurred as a...

BACKGROUND The USCI PDA Umbrella is a device to close patent ductus arteriosus (PDA) by a transcatheter technique. Human clinical trials have shown excellent efficacy in reducing or eliminating the PDA shunt, but concerns remain about the risk of infection with this device. The purpose of this study was to evaluate the risk of infection using an animal model. METHODS AND RESULTS Susceptibilit...

Pancreatic ductal adenocarcinoma (PDA) is the fourth-leading cause of cancer death in the United States with a 5-year overall survival rate of 8% for all stages combined. But this decreases to 3% for the majority of patients that present with stage IV PDA at time of diagnosis. The lack of distinct early symptoms for PDA is one of the primary reasons for the late diagnosis. Common symptoms like ...

Persistent patent ductus arteriosus (PDA) is associated with significant co-morbidities and increased mortality in preterm infants, especially very low birth weight (VLBW) infants. A large number of studies on the management of PDA have been published. Despite PDA being such a common condition in preterm infants, there is no consensus on which PDAs to treat, when to treat and how best to treat....

There are languages A such that there is a Pushdown Automata (PDA) that recognizes A which is much smaller than any Deterministic Pushdown Automata (DPDA) that recognizes A. There are languages A such that there is a Linear Bounded Automata (Linear Space Turing Machine, henceforth LBA) that recognizes A which is much smaller than any PDA that recognizes A. There are languages A such that both A...

Abstract Polydopamine (PDA) has been widely used in the field of energetic materials; however, there are few reports on ammonium perchlorate (AP) coating PDA. In this article, to improve mechanical properties GAP‐ETPE‐based propellant, a two‐step method was coat AP with PDA and glycidyl azide polymer (GAP) based propellant. SEM, EDS, XRD, XPS were analyze morphology composition PDA@AP, while co...

BACKGROUND Methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C gene polymorphisms are associated with the risk of patent ductus arteriosus (PDA) congenital heart defects. This study aimed to determine the association of these polymorphisms in patients with isolated PDA and in non-PDA patients group without congenital heart disease. METHODS This retrospective case-controlled study was...

Several studies showed associations among marital variables and panic disorder with agoraphobia (PDA) symptomatology. However, very few explored this issue using behavioural coding of couples’ interactions. We www.ccsenet.org/ijps International Journal of Psychological Studies Vol. 3, No. 2; December 2011 ISSN 1918-7211 E-ISSN 1918-722X 108 conducted this study to investigate whether observed m...

The deposition of extracellular matrix (ECM) is a defining feature of pancreatic ductal adenocarcinoma (PDA), where ECM signaling can promote cancer cell survival and epithelial plasticity programs. However, ECM signaling can also limit PDA tumor growth by producing cytotoxic levels of reactive oxygen species. For example, excess fibronectin stimulation of α5β1 integrin on stromal cells in PDA ...

Multifunctional nanocomposites that have multiple therapeutic functions together with real-time imaging capabilities have attracted intensive concerns in the diagnosis and treatment of cancer. This study developed epidermal growth factor receptor (EGFR) antibody-directed polydopamine-coated Fe3O4 nanoparticles (Fe3O4@PDA NPs) for magnetic resonance imaging and antitumor chemo-photothermal thera...
