Real-time prostate tracking during intensity-modulated arc radiotherapy requires a reliable prostate position signal during treatment. Many modern linear accelerators have a single gantry-mounted x-ray imager that could be used for intrafraction imaging of implanted prostate markers. The aim of this study was to develop a method to use such a single x-ray imager to estimate the three-dimensiona...

Oxytocin is extensively used to induce or augment uterine contractions, especially to facilitate the third stage of labor in humans. Administration of oxytocin to parturient sows reduces duration of labor whereas mortality of the offspring may remain unchanged. This study aimed to evaluate whether time of administration of oxytocin during parturition may alter the uterine response and fetal out...

The time interval between initiation of surface convergence and the subsequent response of visible cloud growth to this convergence was examined for nine cases of convection that occurred over the FACE 1973 and 1975 mesonetworks in south Florida. Clouds ranged in size from small echoes with a few towers to merged lines or large clusters of towers, but they met a series of observational criteria...

the aim of this study was to investigate the effect of one session of continuous exercise on a treadmill on hsp72 and tac levels of the hippocampus of male wistar rats. for this purpose, 20 male wistar rats (weight 165±1 gr. and age 6 to 8 weeks old) were assigned randomly into four groups: one control group and three acute endurance training groups (groups 1,2 and 3 were killed 30 minutes, 4 h...

in this research, the effect of different concentrations of pectinase has been investigated on deinking of old newspaper (onp). onp re-pulped at 5% consistency for 10 min in disintegrator (with 2650 rpm). enzymatic treatment of recycled onp pulp was done under constant conditions (10% consistency, duration time of 20 min, ph range of 4.5-5) at different pectinase concentrations (0.05, 0.1, 0.2,...

OBJECTIVE This study was designed to explore the timeline of protection against complications in prepubertal children with diabetes, in particular the effects of diabetes duration before age 5 years. RESEARCH DESIGN AND METHODS In this study, 193 adolescents with prepubertal diabetes onset were followed longitudinally for retinopathy (early background and clinical) and microalbuminuria (album...

Introduction: Endoscopic examination of gastrointestinal (GI) system is a diagnostic and therapeutic instrument in children. Endoscopy usually encounters some difficulties because of intensive and spastic response of GI muscles during endoscopic examination. So this study aimed to assess the effect of peppermint essence on satisfaction of patient and therapeutic team during endoscopic examinati...
