introduction electron linear accelerator (linac) can be used for neutron production in boron neutron capture therapy (bnct). bnct is an external radiotherapeutic method for the treatment of some cancers. in this study, varian 2300 c/d linac was simulated as an electron accelerator-based photoneutron source to provide a suitable neutron flux for bnct. materials and methods photoneutron sources w...

background: fast foods consumption among students has increased. this study assessed the factors associated with fast foods consumption in adolescents in the city of sanandaj, iran. methods: in this cross-sectional study, 553 high-school students studying in the city of sanandaj were randomly selected. data were collected using questionnaires proved to be valid and reliable. data were analyzed ...

was to evaluate the prevalence of this complication and its mechanism using heart rate variability analysis. Methods and Results. Time and frequency domain analysis of heart rate was performed in the electrophysiology laboratory immediately before and immediately after RF ablation in 64 patients with supraventricular tachycardia. Ablation targets in these 64 patients included the fast AV nodal ...

A direct commissural connection between cochlear nuclei provides a pathway by which binaural input can influence the processing of acoustic information through the ventral cochlear nucleus. Despite anatomical evidence to suggest the existence of such a pathway, its nature and behavior have not been investigated previously. This in vivo intracellular electrophysiological study provides direct ev...

INTRODUCTION The Liverpool Care Pathway for the Dying Patient is an instrument to deliver integrated care for patients in their last hours of life. Originally a paper-based system, this study investigates the feasibility of an electronic version. METHODS An electronic Liverpool Care Pathway was implemented in a specialized palliative care unit of a German university hospital. Its use is exemp...

The utility of selective radiofrequency catheter ablation of the slow pathway for the treatment of common and uncommon atrioventricular nodal reentrant tachycardia (AVNRT) was studied in 110 consecutive patients, 94 with slow-fast form common AVNRT, and 11 and 5, respectively, with the fast-slow and slow-slow forms of uncommon AVNRT. Ablation sites were determined by mapping a late and spiky "s...

Abstract Training exercise produces skeletal muscle adaptation: at the organ scale, as anatomical changes; and myofiber mitochondrial protein type content. The content of a is controlled by calcineurin‐NFATc signaling pathway: triggers pathway, its final product translocation dephosphorylated NFATc to nucleus. Once in nucleus, controls state gene program encode slow or fast fiber characteristic...

We describe a patient with an implanted pacemaker for impaired AV conduction who presented with an incessant tachycardia. EP study showed that the tachycardia was atrioventricular nodal reentrant tachycardia (AVNRT) with repeated spontaneous initiation because of poor or absent antegrade fast pathway conduction. Slow pathway ablation was successful in terminating the tachycardia and making it n...

Flux balance analysis (FBA) is one of the most often applied methods on genome-scale metabolic networks. Although FBA uniquely determines the optimal yield, the pathway that achieves this is usually not unique. The analysis of the optimal-yield flux space has been an open challenge. Flux variability analysis is only capturing some properties of the flux space, while elementary mode analysis is ...
