Pengobatan kanker pada permukaan kulit menggunakan berkas elektron menghasilkan dosis radiasi yang belum mampu memberikan secara maksimum, sehingga diperlukan material meningkatkan disebut dengan bolus. Penelitian ini akan menguji bolus berbahan campuran Beeswax dan Petroleum Jelly . Pengujian meliputi serap nilai Relative Electron Density (RED). Nilai RED diperoleh dari citra tomografi CT-Simu...

purpose: to compare the morphology and function of corneal enthothelial cell in early postoperative period after phacoemulsification with infusion or bolus intracameral adrenaline. methods: in this prospective randomized study, 71 eyes of 71 patients scheduled for phacoemulsification were randomly assigned to two groups: one group (31 eyes) received bolus intraocular adrenaline at 1/10,000 conc...

A new thermoplastic material with extremely desirable physical and radiation shielding properties is presented. The material softens between 108 degrees F and 132 degrees F and can then be easily molded to any desired shape. As it cools down it hardens at about 102 degrees F, retaining its molded shape. It is very light (rho = 1.66 g/cc), compared to most other compensating and shielding materi...

    Introduction: In the last few decades, a lot of monte carlo codes have been introduced for medical applications. For close - to - surface tumors, the surface of the skin can be used to increase the surface dose so that all or part of the bunch area can fall into bolus, thereby increasing the dose of the skin. The air gaps between bolus and skin can affect the dose of...

background: we investigated the efficacy of a mobile-based  bolus advisor app in comparison with the usual multiple daily  injections (mdis) in diabetic patients. materials and methods: in a nonrandomized, controlled clinical trial, 62 diabetic patients  were selected to receive a 12-week intensive glycemic control by either a mobile-based bolus advisor (app) or mdi in the usual manner.we compa...

OBJECTIVES The aim of this open-label, non-randomized, clinical trial was to evaluate the feasibility of trialing ziconotide by intrathecal bolus injections. MATERIAL AND METHODS Twenty-three patients, who had peripheral neuropathic pain refractory to pharmacological treatment and were under consideration for Spinal Cord Stimulation, received up to three ziconotide bolus injections according ...

INTRODUCTION Computed tomography and magnetic resonance imaging are able to demonstrate and to diagnose hepatic focal nodular hyperplasia when a typical pattern of a well-circumscribed lesion with a central scar is present.Our aim is to propose the split-bolus multidetector-row computed tomography technique as an alternative to the conventional triphasic technique in the detection and character...

BACKGROUND AND AIMS While ephedrine was the preferred drug for treating spinal-induced hypotension in pregnancy, its use has declined because of resultant fetal acidosis. The objective of this randomized control trial was to compare the effects of a slow and rapid bolus of ephedrine on fetal acidosis, maternal blood pressure, and heart rate (HR) during cesarean section performed under spinal an...

Abstract In this study, the feasibility of using electronic portal imaging device (EPID) as an analysing equipment for bolus material was evaluated in terms its dosimetric parameters. Seven superflab samples, 4 samples 0.5 cm (S1–S4) and 3 1 thickness (S5–S7), were analysed compared with tissue equivalent water phantom, which selected reference material. Gamma analysis method used to evaluate d...

Published data on the effects of ruminal bolus on the number of ovulatory follicles in ewes does not exist. The present study determined the effects of a ruminal bolus on trace element status, follicular dynamics and reproductive performance in ewes. Eighty Afshari cycling ewes were synchronized during breeding season using CIDR for 14 days and assigned to 4 groups (n=20); group 1 received a si...
