introduction the first medical intervention for many breast cancer patients is breast conserving surgery (bcs) and/or modified radical mastectomy (mrm). most of these patients undergo radiation therapy, following surgery. the most common side-effect of breast radiotherapy is skin damage. in the present study, the severity of acute skin changes and the underlying causes were investigated in pati...

twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (lp-le), low protein–high energy (lp-he), high protein–low energy (hp-le) and high protein–high energy (hp-he). results showed that the hp-he diet recorded the highest digestibility coefficients of cp, ee, nfe, nutritive values, ...

background: radiotherapy treatment planning requires different dosimetric quantities as input in order to calculate a desired dose distribution. this study has been focused to evaluate the depth dose characteristics of superficial x-rays being used for radiotherapy treatment. materials and methods: computerized 3-d water phantom of multi-data system was used. the measurements were made through ...

NIST developed the alanine dosimetry system in the early 1990s to replace radiochromic dye film dosimeters. Later in the decade the alanine system was firmly established as a transfer service for high-dose radiation dosimetry and an integral part of the internal calibration scheme supporting these services. Over the course of the last decade, routine monitoring of the system revealed a small bu...

PURPOSE/OBJECTIVES To describe experiences during radiotherapy of patients suffering from lung cancer. DESIGN Inductive, qualitative. SETTING A radiotherapy department in the south of Sweden. SAMPLE 15 patients with lung cancer undergoing their second week of radiotherapy. METHODOLOGIC APPROACH Interviews were conducted in a hospital setting, transcribed, and content analyzed. MAIN RE...

Due to the aggressive industrial development in many countries, coupled with an increase in population in some of these countries, the need exists for more advanced and effective techniques for treating wastewater. Recent efforts searching for safe and practical alternatives have resulted in the consideration of the use of irradiation with high-energy electron beams. Such an electron beam can b...

This paper presents a model for the characterization and selection of beeswaxes for use as base substitute tissue for the manufacture of objects suitable for external radiotherapy using megavoltage photon beams. The model of characterization was divided into three distinct stages: 1) verification of aspects related to the origin of the beeswax, the bee species, the flora in the vicinity of the ...

The high radiation tolerance of hydrogenated amorphous silicon (a-Si : H) is one reason it has become a candidate for high-energy physics applications and for radiotherapy and diagnostic imaging. The performance of 1 [,m and 5 [Lm a-Si : H n-i-p photodiode sensors used in conjunction with Lanex (Gd 202S : Tb) intensifying screens has been measured as a function of high-energy photon dose . Over...

Cancer incidence and mortality depend on a number of factors, including age, socio-economic status and geographical location, and its prevalence is growing around the world. Most of cancer treatments include external beam radiotherapy or brachytherapy. Brachytherapy, a type of radiotherapy with energy from radionuclides inserted directly into the tumor, is increasingly used in cancer treatment....
