background and objective: vesicoureteral reflux (vur) is one of the most common urinary tract abnormalities in patients with urinary tract infection. nowadays noninvasive diagnostic methods are suggested to recognize vur and its severity. methods: we measured urinary and serum fibronectin in 51 children with vur. results: the mean serum fibronectin was 318.3±112.1 in children with low grade vur...

the pediatric risk of mortality (prism) score is a measure of illness severity based on abnormalities observed on bedside examination and laboratory assessment at pediatric intensive care unit (picu) admission to predict mortality probability. our study was performed on 205 patients who were admitted to picu of children’s medical center (cmc) over a period of 6 months.data were recorded prospec...

background rheumatoid arthritis (ra) is a chronic inflammatory disease with extra- articular involvement. eyes in particular are one of the most common sites of involvement in rheumatoid arthritis. on the other hand, dry eye syndrome is the most common conflict in terms of management. particular studies suggested dry eye has been associated with greater rheumatoid arthritis severity, but its as...

Toll like receptors (TLRs) with a myeloid differentiation antigen (CD14) recognize and bind various structures from invading microbes and then trigger cell activation. They initiate a variety of effectors' functions, including cytokine secretion, proliferation, co-stimulation or phagocyte maturation. The aim of this study was to evaluate Toll-like receptor 4 (TLR4) and CD14 expression in childr...

Background and Aims: One of the major causes of acute diarrhea in children during the cold season in Iran is infection by rotavirus. Children infected with rotavirus often require hospitalization. Several studies on human and animals have shown that enterotoxigenic Escherichia.coli and rotavirus are the most common coinfection causing diarrhea. There are other reports indicating occurrence of r...

A 40 Gbit/s delay-line interferometer realized in SOI rib waveguide technology is presented. Across the C-band we demonstrate high uniformity, low loss, low PDL, and PDF as low as 1 GHz for the SOI interferometer.

Modern computing infrastructures should enable realization of converged provisioning and governance operations on virtualized computing, storage and network resources used on behalf of users’ workloads. These workloads must have ensured sufficient access to the resources to satisfy required QoS. This requires flexible platforms providing functionality for construction, activation and governance...

NATURE PHOTONICS | VOL 9 | DECEMBER 2015 | www.nature.com/naturephotonics Light consists of electromagnetic waves that oscillate in time and propagate in space. Scalar waves are described by their intensity and phase distributions. These are the spatial (orbital) degrees of freedom common to all types of waves, both classical and quantum. In particular, a localized intensity distribution determ...
