Introduction Hadron-therapy is an effective technique used to treat tumors that are located between or nearby vital organs. The Italian National Center of Oncological Hadron-therapy (CNAO) has been realized as the first facility in Italy to treat very difficult tumors with protons and Carbon ions. The on-line monitor system for CNAO has been developed by the Department of Physics of the Univers...

background: the aim was to assess the reliability and the validity of the translated version of the stroke specific quality of life (ss-qol) questionnaire in iranian post-stroke patients. methods: this project was performed at the shiraz university of medical sciences, shiraz, iran, between 12  april  2010  and  24  february 2011.  the  english version of the ss-qol was translated into persian ...

background: alcohol use disorders (auds) has been recently prioritized as a health problem in iran. the alcohol use disorders identification test (audit) is an easy-to-use diagnostic tool for excessive drinking. this study was designed to assess the validity and reliability of the persian version of audit questionnaire. methods: participants were 70 individuals with aud (study group) and 70 non...

background: the effect of poor psychosocial work conditions on health status has widely been discussed in occupational literature. job content questionnaire (jcq) is a widely accepted instrument for evaluation of psychosocial work conditions. objective: to determine the reliability and validity of persian version of jcq. methods: the questionnaire was translated into persian and back translated...

background: the effect of health status on productivity has widely been studied and discussed in literature. valid and reliable tools are needed to evaluate the levels of health and productivity and provide detailed information, before any intervention is implemented. world health organization health and work performance questionnaire (hpq) is a widely used instrument in estimating the workplac...

Using data from the Centers for Disease Control (CDC) Proficiency Testing (PT) Surveys, we obtained estimates of repeatability (intralaboratory variability between results on the same material) and reproducibility (interlaboratory variability between results on the same material) for the Technicon SMA 6 (or 12/60) and SMAC 1 (or II) systems used with cresolphthalein complexone methodology to me...

Reproducibility is essential to reliable scientific discovery in large-scale high-throughput biological studies. In this talk, I will present a unified approach to measure reproducibility of findings identified from replicate experiments and select discoveries using reproducibility between replicates. Unlike the usual scalar measures of reproducibility, our approach views reproducibility as whe...

The isolated perfused rat kidney experiment was introduced in 1959 for studying the regulation of renal blood flow and is recognized as a valuable preparation for studying physiological and biochemical aspects of renal function such as hemodynamics, glomerular filtration rate (GFR) and overall handling of fluids. Dose-response curves are obtained by injection of bolus doses of drugs into the pe...

In this study, the fluorogenic efficiency of fluorescamine for spectrofluorimetric analysis of primary amines was investigated. Different mixtures of dichloromethane and other organic solvents were used for evaluation of fluorescence stability and intensity of fluorescamine derivative (Pyrrolinone). Solvents such as acetonitrile (ACN), tetrahydrofuran (THF) and dioxane increase stability an...

Venous occlusion plethysmography is commonly used as a tool to assess BF (blood flow) and VR (vascular resistance) at baseline and during PORH (post-occlusive reactive hyperaemia). However, little is known about the reproducibility of this method. The purpose of the present study was to investigate short- (hours) and medium (week)-term reproducibility of forearm, calf and thigh BF and VR at bas...
