background and aims. xerostomia is one of the most common complications of head and neck radiotherapy. the aim of this study was to evaluate and compare the efficacy of pilocarpine and bromhexine in improving radiotherapy-induced xerostomia and its associated symptoms. materials and methods. in this single-blind, randomized crossover study, pilocarpine and bromhexine tablets were used by twenty...

introduction: the aim of this study was to eva-luate the salivation flow rate objectively using schirmer test and mouth dryness and other con sequences subjectively by distributing question naires to patients receiving head and neck radio therapy. materials and methods: in this descriptive study that was carried out at imam khomeini hospital, tehran, iran, the saliva flow rate of 33 patients re...

introduction: nowadays different countries benefit from health system based on health cards and projects related to smart cards. lack of facilities which cover this technology is obvious in our society. this paper aims to design minimum data sets of health smart card system for iran. methods: this research was an applied descriptive study. at first, we reviewed the same projects and guidelines ...

In this study, we investigate the use of multifunctional smart radiotherapy biomaterials (SRBs) loaded with immunoadjuvants for boosting the abscopal effect of local radiotherapy (RT). SRBs were designed similar to currently used inert RT biomaterials, incorporating a biodegradable polymer with reservoir for loading payloads of the immunoadjuvant anti-CD40 monoclonal antibody. Lung (LLC1) tumor...

background depending on the cause, 40-90% of every deep dermis insult ends up in scar formation. several modalities have been suggested as a treatment but a high rate of recurrence is reported in most of those interventions. high dose radiotherapy has been shown to be effective in reducing the recurrence rate. this study tried to determine the effectiveness of low dose rate radiotherapy followi...

breast cancer is the most common cancer in women after skin cancer. in iran, the presentation age of this cancer is younger than the global average. there are different therapeutic methods for treatment of breast cancer and the choice of treatment depends on the stage of the disease as well as its type and characteristics. therapeutic methods include surgery, radiotherapy, and systemic therapie...

normal skin is composed of epidermis and dermis. skin is susceptible to radiation damage because it is a continuously renewing organ containing rapidly proliferating mature cells. radiation burn is a damage to the skin or other biological tissues caused by exposure to radiofrequency energy or ionizing radiation. acute skin reaction is the most frequently occurring side effect of radiation thera...

extended abstract 1. introduction today the irregular growth of the population and its illogical distribution across natural and cultural environments of different communities has necessitated sustainable development in response to the unstable conditions of cities. mashhad is a city with fast growth and development but with no clear plan, especially after land reform program. in this sense, th...

in this research, the buckling and bending behaviour of smart nanocomposite plate reinforced by single- walled carbon nanotubes (swcnts) under electro-magneto-mechanical loadings is studied. the extended mixture rule approach is used to determine the elastic properties of nanocomposite plate. equilibrium equations of smart nanocomposite plate are derived using the hamilton’s principle based on ...
