20 21 Distillers’ Dried Grains with Solubles (DDGS) is the major by-product of bioethanol and distillery 22 plants. Due to its high content of proteins, water-soluble vitamins and minerals, DDGS has been 23 long marketed as animal feed for livestock. EU legislation on liquid biofuels could raise the 24 demand on bioethanol production in Europe, with a resulting increase in DDGS availability. 25...
N. Leigh Anderson Molecular Anatomy Program Division of Biological and Medical Research Argonne National Laboratory Argonne, Illinois 60439 Received June 6,1979 SUMMARY: Using the technique of thermal denaturation in a temperature gradient followed by two-dimensional gel electrophoresis of the fractions, the thermostabilities of the cytoplasmic actins have been investigated. Addition of 5 mM Mg...
The three-dimensional dose, volume, and outcome data for lung are reviewed in detail. The rate of symptomatic pneumonitis is related to many dosimetric parameters, and there are no evident threshold "tolerance dose-volume" levels. There are strong volume and fractionation effects.
BACKGROUND The treatment of oligometastatic disease has become common as imaging techniques have advanced and the management of systemic disease has improved. Use of highly targeted, hypofractionated regimens of stereotactic body radiotherapy (SBRT) is now a primary management option for patients with oligometastatic disease. METHODS The properties of SBRT are summarized and the results of re...
Introduction: Carcinoma of larynx which is linked directly with smoking is emering a very big public heath problem. In our study, we have treated cases of early glottic carcinoma by two different dose fractionation schedules in relation to overall treatment time and have tried to assess the response of two different fractionation schedules. Material and Methods: This is an analysis of 29 patien...
According to Leksell radiosurgery is defined as "the delivery of a single, high dose of irradiation to a small and critically located intracranial volume through the intact skull." Before its birth in the early 60s and its introduction in clinical therapeutic protocols in late the 80s dose application in radiation therapy of the brain for benign and malignant lesions was based on the administra...
BACKGROUND & OBJECTIVE Radiotherapy is an important treatment for nasopharyngeal carcinoma (NPC). Timing of radiotherapy has attracted more attention nowadays. This study was to assess the efficacy of accelerated fractionation (six fractions per week) versus conventional fractionation (five fractions per week) for NPC, thus to improve treatment efficacy without increasing complications. METHO...
Abstract Technological opportunities are explored to enhance detection schemes in transmission electron microscopy (TEM) that build on the of single-electron scattering events across typical spectrum interdisciplinary applications. They range from imaging with high spatiotemporal resolution diffraction experiments at window quantum mechanics, where wave-particle dualism single electrons is evid...
