tea is one of the most important medicinal plants which have a considerable effect on the treatment of cardiovascular disease and cancer. the drying process of tea leaves is carried out by hot air flow which consumes high level energy. the aim of the recent research was to investigate the procedure of high power ultrasound-assisted drying process of tea leaves. hybrid variety of chinese tea was...

BACKGROUND We have constructed a simple, inexpensive simulation model for ultrasound guided nerve blocks. To date there are no low cost, high fidelity models for nerve block simulations. The models that do exist are expensive and vaguely resemble actual anatomy. As ultrasound guided nerve blocks become more common in medical education it is essential to develop better training models to help in...

The low prevalence of fetal central nervous system anomalies results in a restricted level of exposure and limited experience-- for most of the obstetricians involved in prenatal ultrasound. Sonographic guidelines for screening the fetal brain in a systematic way will probably increase the detection rate and enhance a correct referral to a tertiary care center, offering the patient a multidisci...

Initially used in the treatment of prostate cancer and uterine fibroids, the role of focused ultrasound has expanded as transcranial acoustic wave distortion and other limitations have been overcome. Its utility relies on focal energy deposition via acoustic wave propagation. The duty cycle and intensity of focused ultrasound influence the rate of energy deposition and result in unique physiolo...

Introduction: Phonophoresis is the use of ultrasound to enhancing cellular drug delivery through the skin. In this study the effect of clobethasole and hydrocortisone ointments phonophoresis on pain, knee osteoarthritis and some other symptoms was studied. Methods: An experimental single blind randomized clinical trial (RCT) was used. An available sampling technique was used for selection o...

Introduction: Acoustic transient cavitation is the primary mechanism of sonochemical reaction and has potential use for tumor treatment. In this study, the in vivo anti-tumor effect of simultaneous dual-frequency ultrasound at low-level intensity (ISATA < 6 W/cm2) was investigated in a spontaneous murine model of breast adenocarcinoma in Balb/c mice. Materials and Methods: Forty tumor bearing m...
