objective(s) sonodynamic therapy is a physical treatment which utilizes ultrasound waves with an appropriate sensitizer such as protoporphyrin ix (ppix). the activation of sensitizer depends on cavitation, and therefore, high intensity ultrasound is an important necessity. beside, high intensity ultrasound can induce side effects on the healthy tissues which have surrounded tumor. the particles...

Introduction: One of the combination therapies for the treatment of cancer is ultrasound with other agents, which has received considerable attention in recent years. Ultrasound causes cavitation phenomenon that can produce some effects, such as; Reactive Oxygen Species (ROS), which results in damage to cancer cells. When a particle is in liquid, the cavitation threshold decrea...

BACKGROUND Past catheter-based and focused ultrasound renal denervation studies have indicated that procedure efficacy is related to the number of ablations performed or the amount of energy used for the ablation. This study extends those prior results and investigates energy level effects on the efficacy of MR guided focused ultrasound renal denervation performed in a porcine model. METHODS ...

a 30-year-old woman presented with a palpable subcutaneous nodule in the areolar region of the left breast. sonomammographic examination revealed 2 cystic lesions showing typical “filarial dance” as vigorous twirling movement of multiple curvilinear echoes with mixed red blue color doppler signals that was non-rhythmic, nonpulsatile, and the characteristic pulse doppler trace due to irregular w...

twin reversed arterial perfusion (trap) sequence is a syndrome with poor prognosis, seen only in monochorionic monozygotic twin pregnancies. the incidence is one in 35.000 births and one in 100 monozygotic twin pregnancies. it is characterized with a recipient fetus exhibiting lethal anomalies including acardia and a pump fetus. mortality is usually due to heart failure or premature labor cause...

Instruments based on airborne/structure borne ultrasound technology offer many opportunities for reducing energy waste and improving asset availability in plants. They expand the concept of ”Condition Monitoring” to include much more than basic mechanical fault inspections. Since these instruments detect friction, ionization and turbulence, their inspection capabilities range from trending bear...

Carcass traits have been successfully used to determine body composition of steers. Body composition, in turn, has been used to predict energy content of ADG to compute feed requirements of individual animals fed in groups. This information is used in the Cornell value discovery system (CVDS) to predict DM required (DMR) for the observed animal performance. In this experiment, the prediction of...
