background: worldwide, cervical cancer is one of the most challenging gynecologic cancers in treatment. objectives: this study was designed with the aim of comparing patients treated with external beam radiotherapy (ebrt) and interactivity brachytherapy (icbt) with ebrt and extrafascial hysterectomy in locally advanced stages of cervical cancer (iib-iii). patients and methods: the present study...

to be fairly general and catalyst is easily separated by magnetic devices and can be reused without any apparent loss of activity for the reaction. fe3o4 nanoparticles were prepared by chemical coprecipitation method and was found to be a mild and effective catalyst for the efficient, one-pot, three-component synthesis of 2,4,5-trisubstituted imidazoles at room temperature under ultrasound irra...

background: emulsions are thermodynamically unstable systems that can be kinetically stable by adding substances known as emulsifiers and/or thickening agents. by respect to the functional properties of gum tragacanth (gt), and its breakage probability during irradiation treatment, the major aim of this study was to investigate the stability of oil in water emulsion in the presence of different...

objective(s):cervical cancer is a malignancy that is the second most common cause of death from cancer in women throughout the world. paederus beetle (paederus fuscipes) extract (pbe), contains bioactive compounds such as pederine which has cytotoxic properties and blocks dna and protein synthesis at very low concentrations. in this investigation we tried to determine the effects co-treatment w...

ultrasonic technology as an innovative technology may be used for water and wastewater treatment for pollution removal. this technology acts as an advanced oxidation process. application of this technology leads to the decomposition of many com­plex organic compounds to much simpler compounds during physical and chemical compounds during cavitation proc­ess. in this article review, some applica...

results histopathologically, a decrease (statistically not significant) in the thickening of alveolar or bronchial wall, formation of fibrous bands, and superimposed collagen were noted in the animals in group b as compared to the animals in group a. conclusion in this experimental study, administration of gla one hour before thoracic irradiation may be a protective agent against radiation-indu...

introduction: although dental caries is a preventable disease, it is still common and remains a public health problem. one of the potentially effective preventive measures is the use of lasers. the purpose of this study was to review the studies about use of laser irradiation on the inhibition of carious lesions and the effectiveness of different commercial laser type (nd:yag, co2, and argon). ...

In perceptual filtering tasks, congruency effects vary as a function of proportion congruent (PC), with smaller congruency effects when congruent trials are rare than when they are frequent. This effect is typically larger with extreme differences between high and low proportion congruent conditions (e.g., 80% congruent-20% incongruent) than with intermediate differences (e.g., 60% congruent-40...

introduction: transient cavitations induced by low frequency irradiation of ultrasound can be used to treat tumors. previous studies in in-vitro experiments have shown that induced cavitation by dual or multiple frequencies of ultrasound is greater than induced cavitation by single frequency irradiation. in this study, we compared and evaluated the treatment effects of dual frequency irradiatio...
