Functionalised titanate nanotubes (TiNTs) were incorporated to poly(5,5-bisbenzimidazole-2,2-diyl-1,3-phenylene) (PBI) or poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) for improving the interfacial compatibility between the polymer matrix and inorganic material and for altering the gas separation performance of the neat polymer membranes. Functionalisation consisted in oxidative polymerisation o...

UNLABELLED Pancreatic ductal adenocarcinoma (PDA) is the most lethal form of human cancer, with dismal survival rates due to late-stage diagnoses and a lack of efficacious therapies. Building on the observation that avian influenza A viruses (IAVs) have a tropism for the pancreas in vivo, the present study was aimed at testing the efficacy of IAVs as oncolytic agents for killing human PDA cell ...

Two Parallel Interference Cancellation (PIC) schemes, based on the Probabilistic Data Association (PDA) approach are evaluated with respect to the allowable load. The N-dimensional PDA detector achieves an acceptable load that is more than three times higher than that of the one-dimensional detector. An improvement of these PIC schemes is proposed by replacing the a priori probabilities in ever...

A patent ductus arteriosus (PDA) results in increased pulmonary blood flow and redistribution of flow to other organs. Several co-morbidities (i.e., necrotizing enterocolitis, intracranial hemorrhage, pulmonary edema/hemorrhage, bronchopulmonary dysplasia, and retinopathy) are associated with the presence of a PDA, but whether or not a PDA is responsible for their development is still unclear. ...

Four-element modified uni-traveling-carrier (MUTC) photodiode arrays (PDA) flip-chip bonded onto transmission lines on AlN substrates are demonstrated. High RF output powers of 26.2 dBm and 21.0 dBm are achieved at 35 GHz and 48 GHz, respectively, using a PDA with 28-μm diameter photodiodes. A systematic comparison between a PDA with four 20 μm-diameter elements and a discrete detector with the...

An adult with a large patent ductus arteriosus may present with fatigue, dyspnea or palpitations or in rare presentation with endocarditis. The case illustrated unique role of vegetation of endocarditis in hemolytic anemia in adult with patent ductus arteriosus (PDA). Despite treatment of endocarditis with complete course of appropriate antibiotic therapy and normality of C- reactive protein, e...

The incidence of patent ductus arteriosus (PDA) in premature neonates varies according to the gestational age and respiratory status. Failure of PDA closure in preterm infants with respiratory distress syndrome results in a left to right shunt across the duct which may lead to pulmonary congestion and deterioration in respiratory status. Although indomethacin and ibuprofen are the main stay of ...

INTRODUCTION Recently, the prevalence of childhood obesity is increasing significantly. Dietary and physical activity registers are frequently referred to as the "cornerstone" of behavioral weight control programs. Mobile devices such as Personal Digital Assistants (PDAs) are showing their usefulness to facilitate these self-registers. OBJECTIVE This study is aimed to analyze and compare the ...

OBJECTIVE To determine Patent ductus arteriosus (PDA) closure rates for extremely preterm infants in a tertiary care centre, factors affecting response to indomethacin and outcomes of these infants relative to their PDA status. SETTING Neonatal intensive care unit in tertiary-care children's hospital. DESIGN Retrospective medical record review. METHODS A retrospective chart review of all ...

BACKGROUND The indications and strategies for treatment of patent ductus arteriosus (PDA) are controversial, and the safety and long-term benefits of surgical PDA closure remain uncertain. The aim of this study was to compare the lung function of very low birth weight (VLBW) infants after successful PDA treatment with a cyclooxygenase inhibitor or secondary surgical ligation. METHODS A total ...
