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...

EBRT: electron beam radiation therapy GRT: Grenz ray therapy HHD: Hailey-Hailey disease INTRODUCTION Hailey-Hailey disease (HHD), or familial benign chronic pemphigus, is an autosomal dominant genodermatosis. In this condition, dysregulation of intracellular calcium homeostasis leads to impaired desmosome function and suprabasilar acantholysis of the epidermis. Clinically, this condition presen...

this research was performed to compare electron beam (eb) and gamma ray (gr) treatments at doses of 25, 50 and 75 kilo gray (kgy) on ruminal degradation kinetics and in vitro digestibility of sunflower meal (sfm). ionizing radiations of eb and gr had significant effects )p

the current study evaluated the effects of electron beam (eb; 10, 20, 30 and 40 kgy), urea and naoh treatments on chemical composition, phenolic compounds, in vitro gas production and in situ ruminal degradability of pistachio by-product (pb). the eb decreased (p < 0.01) neutral detergent fiber (ndf), acid detergent fiber (adf) and acid detergent lignin (adl) contents of pb. treating pb by naoh...

AIMS To analyse the prevalence, and diagnostic and therapeutic consequences, of accidental findings in electron-beam tomographic scans performed for evaluation of coronary artery calcification. METHODS AND RESULTS A total of 1812 consecutive patients with known or suspected coronary artery disease underwent electron-beam tomography. In 583 (32%) of the patients, i.v. contrast was also adminis...

AIM To investigated the dose enhancement due to the incorporation of nanoparticles in skin therapy using the kilovoltage (kV) photon and megavoltage (MV) electron beams. Monte Carlo simulations were used to predict the dose enhancement when different types and concentrations of nanoparticles were added to skin target layers of varying thickness. METHODS Clinical kV photon beams (105 and 220 k...

Cutaneous lymphomas are particularly radiosensitive and amenable to palliative radiation therapy. Total skin electron beam therapy (TSEB) is effective for palliation of Sézary syndrome and cutaneous T-cell lymphoma with large body surface area involvement. Focal radiation therapy is often used for treatment of localized disease. Treatment of cutaneous T-cell lymphoma can often pose technical ch...
