instruction: measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. it is known that the artery diameter is increased by flow stimulation. therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was assessed. also the biomechanical behavior of th...

we have already shown that low intensity pulsed ultrasonic treatment increases rabbit radial fracture healing. the present experiment was undertaken to find out the best duration for treatment. a complete transverse fracture was made in the right radial bones of21 adult male rabbits by a stanley knife. the animals were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental gro...

restrictions on the use of synthetic antioxidant such as butylated  hydroxyanisole  (bha) and butylated  hydroxytoluene (bht) are being imposed  because of  their carcinogecity. in this investigation  optimization  of phenolic extraction  process  frome  methanolic (80%)  extract (v/v) of  elaegnus  angustifolia  through  response  surface methodology  by fulin cio- calteu is  performrd  for op...

objective: in order to overcome the limitation of systemic administration of methylene blue, this study investigated the encapsulation of methylene blue in polymeric liposomes and drug release following sonication. methods: we encapsulated methylene blue into nanoliposomes. the dynamic light scattering (dls) method was used to measure the size distribution of the liposomes. after loading methyl...

background: ovarian immature teratoma is a very rare type of tumor associated with a high relapse rate and mortality. correspondingly, early diagnosis is important for effective treatment. the goal of this study was to retrospectively analyze the ultrasound characteristics of 11 cases of immature teratomas. materials and methods: between january 2002 and december 2010, 11 patients were diagnose...

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...

purpose: transcranial magnetic resonance guided focused ultrasound (mrgfus) is a new development in the field of functional neurosurgery. a comprehensive review of the current literature was performed to evaluate of transcranial mrgfus in treatment of essential tremor (et) and parkinson’s disease. methods: articles available in electronic databases of pubmed, and web of science, as of july 2016...

in light of provided progresses in ultrasound measurements of lateral abdominal muscles, an important role for these muscles, particularly transverse abdominis (tra) muscle in stability of the spine has been suggested. some authors have found significant correlations between body mass index (bmi) and thickness of these muscles. the aim of this study was to examine possible association between d...

conclusions it seems that fast examination for intra-abdominal fluid in blunt trauma patients can predict intra-abdominal injuries with very high sensitivity and specificity. using the scoring system can more accurately determine the probability of the presence of abdominal injuries with a cut-off point of three. results the mean age of the patients was 29.6 ± 18.3 years and fast was positive i...

Background Meconium ileus (MI) is one type intestinal obstruction due to inspissated meconium at the level of the terminal ileum. The purpose of this study is to present the non-ionizing ultrasound-guided approach for the treatment of meconium ileus. Materials and Methods This study was performed, prospectively, at Dr. Sheikh and Akbar children's Hospitals, Mashhad University of Medical Science...
