Radiation Therapy Medical Physics Review – Delivery, Interactions, Safety, Feasibility, and Head to Head Comparisons of the Leading Radiation Therapy Techniques [PDF]

open access: yes, 2017
Radiation therapy uses high energy radiation to kill cancer cells. Radiation therapy for cancer treatment can take the form of photon therapy (using x-rays and gamma rays), or charged particle therapy including proton therapy and electron therapy. Within

Digital lattice gauge theories

open access: yes, 2017
We propose a general scheme for a digital construction of lattice gauge theories with dynamical fermions. In this method, the four-body interactions arising in models with $2+1$ dimensions and higher, are obtained stroboscopically, through a sequence of ...

Monoaminergic modulation of photoreception in ascidian:evidence for a proto-hypothalamo-retinal territory [PDF]

open access: yes, 2012
Background : The retina of craniates/vertebrates has been proposed to derive from a photoreceptor prosencephalic territory in ancestral chordates, but the evolutionary origin of the different cell types making the retina is disputed.

Sex Differences in Health‐Related Quality of Life in Patients With Head and Neck Cancer—A Prospective Study

open access: yesInternational Journal of Dental Hygiene, EarlyView.
ABSTRACT Objective To analyse sex differences in health‐related quality of life (HRQL) before, during and up to 3 months posttreatment of head and neck cancer, and to examine the importance of salivary secretion rate for HRQL posttreatment. Methods Patients were recruited before starting curative oncologic treatment.

Volumetric modulated arc planning for lung stereotactic body radiotherapy using conventional and unflattened photon beams: a dosimetric comparison with 3D technique

open access: yesRadiation Oncology, 2011
Purpose Frequently, three-dimensional (3D) conformal beams are used in lung cancer stereotactic body radiotherapy (SBRT). Recently, volumetric modulated arc therapy (VMAT) was introduced as a new treatment modality. VMAT techniques shorten delivery time,

Radion Inflation in Higher-Dimensional Gravity Theory

open access: yes, 2012
We study a radion model for inflation and density perturbation identifying the scalar field arising from the five-dimensional gravity on $M_4 x S^1$ with the inflaton.

A Multi‐Institutional Retrospective Study of 21 Dogs Having Undergone Hypofractionated Radiotherapy for Adrenal Tumours (2017–2024)

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT Radiation therapy (RT) has emerged as a promising non‐surgical approach for treating canine adrenal tumours. This multi‐institutional, retrospective study describes clinical outcomes for 21 dogs having been prescribed a course of hypofractionated image‐guided intensity‐modulated RT (IMRT) entailing delivery of 25–35 Gy total in 5 fractions ...

A Dosimetric Study of Using Fixed-Jaw Volumetric Modulated Arc Therapy for the Treatment of Nasopharyngeal Carcinoma with Cervical Lymph Node Metastasis. [PDF]

open access: yesPLoS ONE, 2016
PURPOSE:To study the dosimetric difference between fixed-jaw volumetric modulated radiotherapy (FJ-VMAT) and large-field volumetric modulated radiotherapy (LF-VMAT) for nasopharyngeal carcinoma (NPC) with cervical lymph node metastasis.

Patterns of CT lung injury and toxicity after stereotactic radiotherapy delivered with helical tomotherapy in early stage medically inoperable NSCLC [PDF]

open access: yes, 2015
To evaluate toxicity and patterns of radiologic lung injury on CT images after hypofractionated image-guided stereotactic body radiotherapy (SBRT) delivered with helical tomotherapy (HT) in medically early stage inoperable non-small-cell lung cancer ...

Retrospective Analysis of Survival and Adverse Effects Associated With Stereotactic Body Radiation Therapy in 12 Dogs With Hepatocellular Carcinoma

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT This retrospective analysis evaluated 12 dogs with hepatocellular carcinoma (HCC) who received stereotactic body radiation therapy (SBRT). Dogs received between 6 and 25 Grey (Gy) per fraction for 1–5 fractions for a total dose of 13–30 Gy. Eleven patients (92%) experienced acute adverse effects (AE), with the majority being VRTOG grade 2–3 ...
