Aims: Mustard gas is an alkalizing substance that can lead to damage to DNA and intracellular enzymes. The aim of this study was to investigate the expression of CXCL10 in chemically-injured veterans’ lung tissue.  Materials & Methods: This case-control study was done on 16 lung paraffin blocks of individuals exposed to mustard gas and 7 lungs paraffin blocks not-exposed people as...

BACKGROUND Lung cancer patients are often in poor physical condition, and a shorter treatment time would reduce their discomfort. Dynamic conformal arc therapy (DCAT) offers a shorter treatment time than conventional 3D conformal radiotherapy (3D CRT) and is usually available even in departments without inverse planning possibilities. We examined its suitability as a treatment modality for lung...

Background: The human body contains of different tissues and cavities with different physical and radiological properties. Most important among these are tissues and cavities that are radiologically different from water, including lungs, sinuses and bones. Gel dosimetry provides a unique feature to display dose distributions occurring in clinical radiation therapy in three dimensions. Materials...

The clinical use of Proton Beam Therapy (PBT) in the management cancer is increasing worldwide. USA has high number proton therapy centres and this growing with new under development. This study expresses views experts from 12 US cities based 9 states respect to role treatment. An E-survey was conducted assess clinical, technical, educational, organizational resources strategies -based faciliti...

Introduction: Introduction: Radiation causes damage to irradiated tissues and also tissues that do not receive direct irradiation through a phenomenon called bystander effects. Melatonin as a potent antioxidant and anti-inflammatory agent is known for protection of normal tissues against ionizing irradiation. In addition, some studies have suggested that Melatonin may have some...

An electronic portal imaging device (EPID) is an effective detector for in vivo transit dosimetry. In fact, it supplies two-dimensional information, does not require special efforts to be used during patient treatment, and can supply data in real time. In the present paper, a new procedure has been proposed to improve the EPID in vivo dosimetry accuracy by taking into account the patient setup ...

introduction: this study investigates to what extent the computed dose received by lung tissue in a commercially available treatment planning system (tps) for 192ir high-dose-rate breast brachytherapy is accurate in view of tissue inhomogeneities and presence of ribs. materials and methods: a ct scan of the breast was used to construct a patient-equivalent phantom in the clinical treatment plan...
