Objectives: To assess pediatrics residents’ self-reported competency in placing peripheral intravenous (IV) lines at baseline; to conduct a peripheral intravenous simulationbased training session for residents; and to measure peripheral intravenous (PIV) competency on manikins following the intervention as well as changes in scores of self-reported knowledge, confidence, and success from baseli...

The topological index of a graph G is a numeric quantity related to G which is invariant under automorphisms of G. The vertex PI polynomial is defined as PIv (G)  euv nu (e)  nv (e). Then Omega polynomial (G,x) for counting qoc strips in G is defined as (G,x) = cm(G,c)xc with m(G,c) being the number of strips of length c. In this paper, a new infinite class of fullerenes is constructed. ...

With the development of computers and their surrounding equipments, the simulation of complicated flow structures around aircrafts will further become easier and cheaper by applying computational fluid dynamics. However, in order to judge whether the flow field obtained is reasonable or not, turbulent models and/or numerical schemes should be selected based on the comparison with experimental r...

We designed a prospective study to describe the clinical impact of the parainfluenza viruse (PIV) types detected in hospitalized children with respiratory tract infections from September 2008 to August 2010 in Spain. PIV infections were a significant proportion of viral respiratory detections (11.8% of cases). PIV types 3 and 4 were most commonly detected. There were clinical differences betwee...

according to statistical data from who, respiratory tract infections are among the most important health problems all over the world. differentiating viral from other causes of respiratory infections is difficult, but a good knowledge of viral etiologic factors can guide the physicians in the diagnosis and treatment of the disease. we carried out this descriptive, case-series study to evaluate ...

Four dinuclear lanthanide complexes [Gd2 (H2L)2 (µ-piv)2 (piv)2]·2CHCl3 (1), [Tb2 (H2L)2 (µ-piv)2 (piv)2]·2CHCl3 (2), [Dy2 (H2L)2 (µ-piv)2 (piv)2]·2CHCl3 (3) and [Eu2 (H2L)2 (µ-piv)2 (piv)2]·2CHCl3 (4) were synthesized by the reaction of appropriate Ln(III) chloride salts and a multidentate ligand, 2,2'-(2-hydroxy-3-methoxy-5-methylbenzylazanediyl)diethanol (H3L) in the presence of pivalic acid...

Clinical presentations for viral respiratory tract infections are often nonspecific, and a rapid, high-throughput laboratory technique that can detect a panel of common viral pathogens is clinically desirable. We evaluated two multiplex reverse transcription-PCR (RT-PCR) products coupled with microarray-based systems for simultaneous detection of common respiratory tract viral pathogens. The NG...

Respiratory disorders are major concern for dairy cattle industry. Viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. The most important viral agents arebovine viral diarrhoea virus (BVDV), bovine herpes virus type 1 (BHV-1), bovine respiratory syncytial virus(BRSV), parainfluenza virus type 3 (PIV-3) and bovine adenovirus (BAV). This cros...

Parainfluenza virus (PIV) infections may be significant causes of morbidity and mortality in patients undergoing stem cell transplantation, but data regarding their impact on transplant-related mortality is limited. This study sought to determine the risk factors of PIV acquisition and progression to lower respiratory tract infection, their impact on transplant-related mortality, and the effect...
