introduction: the purpose of this work was to study the ability of mri normoxic polymer gel dosimetry for evaluating the dose distribution in hdr brachytherapy of esophagial cancer at imam reza brachytherapy center (mashhad, iran). materials and methods: initially, 2liters of normoxic gel (magic) was fabricated and then poured into 12 calibration test tubes and placed in a perspex walled phanto...

Aluminophosphate-5 (AlPO4-5) nano-pore zeolite was synthesized. The effect of alteration in precursor gel preparation on the morphology of zeolite was studied. The effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of AlPO4-5 zeolite been studied. A hydrothermal synthesis has been used to produce nano-pore Aluminophosphate-5 c...

Background:  In this study a series of basic dosimetric properties of a low-density (LD) gel dosimeter are investigated. The dose response is studied regarding to linearity, sensitivity, dose-rate and energy dependence as well as lung tissue equivalence. Materials and Methods: The LD gel was made by mixing the polymer gel with expanded polystyrene spheres. Energy dependence was studied...

Introduction: Alveolar osteitis (AO) is one of the most common postoperative complications after third molar surgery. Various techniques have been used to reduce the risk of AO. The aim of the current study was to evaluate the effect of Chlorhexidine (CHX) bioadhesive gel in preventing the development of AO. Methods: Patients with bilateral impacted mandibular third molars underwent surgical ex...

Our objective was to investigate the first-pass effect to the uterus of progesterone gel administered vaginally. This was a prospective, randomized study of 32 postmenopausal women, attending our menopause clinic. All women used transdermal estradiol (50 microg/day, a patch each week) for 2 weeks. They used either vaginal progesterone gel or intramuscular progesterone in oil 50 mg after 24 h to...

In the present work, stress was given for improvised local action of the drug with the addition of mucoadhesive polymer in the formulation. Oral mucoadhesive semi solid gel was prepared for the treatment of oral sub mucous fibrosis, which provides effect for extended periods of time. Curcumin was taken as a model drug as it exhibits profound antitumeric & antimutogenic activity. The semisolid p...
