The effects of irradiation on different cell compartments in the submandibular gland were analyzed in adult C57BL/6 mice exposed to X-ray irradiation and followed up for 10 days. Apoptosis was quantified using the terminal deoxynucleotidyl transferase (TdT)-mediated dUTP-digoxigenin nick end labeling method (TUNEL). Cell proliferation was detected using immunohistochemistry for proliferating ce...

In order to develop X-ray probes for Compton scattering on warm dense plasmas K-lines have been investigated by irradiation of solid targets with intense ultra-short pulsed lasers, e. g. spectroscopy of chlorine Kα (2p→ 1s) and Kβ (3p→ 1s) was performed at Europa Laser Facility LLNL. Measurements of the characteristic X-ray emission show that average line positions shift as function of laser en...

The organic thiophosphate, amifostine, is a promising pharmacological compound showing selective protection in many tissues against the toxic side-effects of radiation and cytotoxic drugs. The aim of the present study was to assess the radioprotective effects of amifostine on ovarian follicles. Three-week-old female mice, with or without pretreatment with amifostine, were irradiated with 6.42 G...

The Lin28/let-7 axis plays an important role in tumor initiation and developmental processes. Lin28B is upregulated in a variety of cancers, and its overexpression enhances cancer cell proliferation and radioresistance through the suppression of let-7 micro RNA expression. In this study, we investigated the role of the Lin28/let7 axis as a target for radiosensitization of melanoma cancer cells....

A novel polyaniline/Bi(2)SnTiO(7 )composite polymer was synthesized by chemical oxidation in-situ polymerization method and sol-gel method for the first time. The structural properties of novel polyaniline/Bi(2)SnTiO(7) have been characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and X-ray spectrometry. The lattice parameter of Bi(2)SnTiO(7) was f...

Helium ion (He(+)) beam produced by a heavy ion linear accelerator was used to simulate α-rays for studying the radiation effect on 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquid ([C4mim][NTf2]). The water-soluble radiolytic products of [C4mim][NTf2] under He(+) beam irradiation were analysed, and it was found that they were similar to those by γ-ray irradiation, but...

X-ray irradiation with convergent chemicals such as nano-silver particles or sodium dichloroisocyanurate (NaDCC) has been used to control leaf blight on cut lilies. The oriental hybrid lily cultivars Siberia, Le Reve, and Sorbonne were irradiated five times by 200 Gy of X-rays in 2014. In 2015, Siberia and Sorbonne were irradiated three times by 150 Gy of X-rays. After artificial infection with...

We have reported the thermoluminescence (TL) response of five different diameters ~120, 241, 362, 483, and 604 μm of 6 mol percent Ge-doped optical fibres. The perfomance of the Ge-doped optical fibre are compared with commercially available TLD-100 chips (LiF:Mg,Ti) in terms of their sensitivity and minimum detectable dose (MDD). The irradiation was performed using X-ray machine (Model ISO ‘Na...

In a repeated radiotherapy owing to a local recurrence close to the previous irradiation, the dose distribution of next irradiation is required to avoid overlap with previous one. Therefore, a system for displaying dose-distribution image of previous irradiation on a present anatomical image would be helpful in designing new radiotherapy. However, registration of two abdominal CT images acquire...
