in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test...

This thesis presents a real-time capable GPU-based ultrasound simulator suitable for medical education. Two different models are presented in the following. A 2D version has been implemented in order to simulate IVUS without modelling complex 3D geometry and a 3D version which is able to synthesize realistic looking ultrasound images in real-time. This includes ultrasound specific artifacts, wh...

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...

Radial artery catheters are commonly placed for continuous blood pressure monitoring, frequent arterial blood gas analysis, or frequent blood sampling for diagnostic testing. Radial artery cannulation can be challenging and ultrasound guidance has emerged as a valuable adjunct for the placement of radial artery catheters. The advantages of ultrasound guidance include: real-time visualization of...

Nanoemulsion is an alternative and promising approach to overcome insolubility and bioavailability problems of bioactive compounds. In this study, the sonication parameter for preparing nanoemulsions with high α- tocopherol and linolenic acid content were optimized by using response surface methodology and their stability were evaluated during 2 months’ storage. The response surface analysis re...

a 29-year-old woman with systemic lupus erythematosus (sle) presented with palpitation and neck swelling. initial sonography showed an ill-defined hypoechoic lesion in the right thyroid gland, mentioning subacute thyroiditis. the patient received conservative care for one week. however, her neck swelling worsened and she complained of dyspnea. follow up sonography showed marked enlargement of b...

lingual thyroid (lt) is a rare developmental thyroid anomaly usually affecting. although the exact pathogenesis of this ectopic, accessory thyroid tissue is not known, it generally originates from epithelial tissue of non-obliterated thyroglossal ductus. in this report, a case of lingual thyroid in a 45- year old male patient with difficulty in breathing and swallowing complaints for five years...

inulin is widely distributed throughout the plant kingdom. it has been increasingly used in various foods due to its beneficial nutritional attributes as prebiotic ingredient. the helianthus tuberosus could be a source of inulin, but scarce studies about its extraction exist. ultrasound has attracted considerable interest in food science and technology due to its promising effects in food proce...
