PURPOSE To determine the effect on machine output calibration, following the TG-51 protocol, as the water temperature increasingly deviates from Standard temperature (22°C) METHODS: A water tank was set up according to TG-51 protocol. Two sets of measurements were taken and the pressure recorded. The measurements consisted of readings at different temperatures. In the first set, P(ion), P(pol),...

Ectonucleotide pyrophosphate phosphodiesterase (ENPP1) has been shown to negatively modulate insulin receptor and to induce cellular insulin resistance when overexpressed in various cell types. Systemic insulin resistance has also been observed when ENPP1 is overexpressed in multiple tissues of transgenic models and attributed largely to tissue insulin resistance induced in skeletal muscle and ...

BACKGROUND HDR brachytherapy is one of the commonest methods of nasopharyngeal cancer treatment. In this method, depending on how advanced one tumor is, 2 to 6 Gy dose as intracavitary brachytherapy is prescribed. Due to high dose rate and tumor location, accuracy evaluation of treatment planning system (TPS) is particularly important. Common methods used in TPS dosimetry are based on computati...

introduction: brachytherapy is the use of small encapsulated radioactive sources in close vicinity of tumors. various methods are used to obtain the dose distribution around brachytherapy sources. tg-43 is a dosimetry protocol proposed by the aapm for determining dose distributions around brachytherapy sources. the goal of this study is to update this protocol for presence of bone and air inhom...

Introduction: 192Ir is one of the important sources frequently used in brachytherapy. Up to now, a lot of commercial models of this source have been made which Ir-192 has been recently added to them. The aim of the present study is to determine the dosimetric parameters of this new source model based on the recommendations of TG-43(U1) protocol using Monte Carlo simulation tech...

A protocol was developed to measure the glass transition temperature (Tg) of brown rice kernels using dynamic mechanical thermal analysis (DMTA). In order to accommodate the sample requirements of the dynamic mechanical thermal analyzer and prevent moisture loss during experiments, kernels were first wrapped with a thin layer of parafilm and then a thin layer of aluminum foil. The wrapped kerne...
