Radiation-induced lung injury (RILI) due to nuclear or radiological exposure remains difficult to treat because of insufficient clinical data. The goal of this study was to establish an appropriate and efficient minipig model and introduce a thoracic computed tomography (CT)-based method to measure the progression of RILI. Göttingen minipigs were allocated to control and irradiation groups. The...

Background: GTS, PTSM and ATSM are bis-thiosemicarbazone ligands used in the preparation of copper radiopharmaceuticals. Chemical structure of these materials indicates that they should have radio-protective effects.Objective: To study the radio-protective effects of GTS, PTSM and ATSM. Methods: This study has focused on radio-protective effects of these compounds at different doses (20, 40 and...

Severe xerostomia is a common late radiation consequence, which occurs after irradiation of head and neck malignancies. The aim of the present study was to analyze apoptosis and proliferation and their relationship during the late post-irradiation phase. C57BL/6 mice were locally irradiated in head and neck region with a single dose of 7.5 or 15 Gy and their submandibular glands were collected ...

PURPOSE To evaluate the impact of splenic irradiation as a palliative treatment for symptomatic splenomegaly due to secondary myelofibrosis. METHODS Seventeen patients with chronic myelogenous leukemia and 3 with idiopathic polycythaemia presented with splenomegaly, splenic pain and anemia. Due to symptomatic splenomegaly, despite first-line treatment, the patients underwent splenic irradiati...

OBJECTIVE This study aimed at comparing the effect of linear polarized near-infrared light irradiation (PL irradiation) and bicycle exercise with 50%HRreserve on the flexibility of the shoulder joint. DESIGN Placebo-controlled trial. SETTING Twenty-four healthy young adults (10 males: mean+/-SD, age 20.9+/-3.1 y, height 171.0+/-3.9 cm, body mass 63.4+/-3.5 kg and 14 females: age 21.2+/-1.7 ...

Ground-based studies on space radiation indicate that exposure to charged particle radiation at relatively low doses may impair neuronal functions. Decrements in excitatory synaptic transmission and plasticity in the hippocampus have been previously reported in mouse brains irradiated with iron nuclei, but relatively little is known about the effects of protons on the synaptic activity in the h...

Irradiation-Dependent Photovoltaic Parameters In article number 2300043, Peter Müller-Buschbaum and co-workers present a detailed analysis of irradiation-dependent photovoltaic parameters perovskite organic solar cells exposed to space conditions. The post-flight characterization elucidates the impact sole transport versus rocket launch, flight, reentry stress.

Introduction It is well known that the wear resistance of ultra-high molecular weight polyethylene (UHMWPE) improves in proportion to the crosslinking irradiation dose. It is also well known that the mechanical properties and oxidative stability of UHMWPE are affected by the irradiation dose, resin type, and post-irradiation heat treatment, among others factors. Therefore, careful consideration...

Sádecká J. (2007): Irradiation of spices – a review. Czech J. Food Sci., 25: 231–242. Food irradiation is a process of exposing food to ionising radiation such as gamma rays emitted from the radioisotopes 60Co and 137Cs, or high energy electrons and X-rays produced by machine sources. The use of ionising radiation to destroy harmful biological organisms in food is considered a safe, well proven...

The purpose is to evaluate the effect of UV irradiation on the bond strength between epoxy-based glass fiber posts and resin cement. Twelve epoxy-based glass fiber posts were randomly divided into three groups. Group 1 (Cont.): No surface treatment. Group 2 (Low-UV): UV irradiation was conducted from a distance of 10 cm for 10 min. Group 3 (High-UV): UV irradiation was conducted from a distance...
