background tomosynthesis is a new technology of digital mammography that enables the acquisition of a three - dimensional image and allows visualization of cancers not apparent by conventional mammography. ultrasound (us) is also used for tumor monitoring, which is highly operator dependent and has some problems with reproducibility. us is also an easily available and noninvasive modality. our ...

introduction: distal radius fractures are a common traumatic injury, particularly in the elderly population. in the present study we examined the effectiveness of ultrasound guidance in the reduction of distal radius fractures in adult patients presenting to emergency department (ed). methods: in this prospective case control study, eligible patients were adults older than 18 years who presente...

background & aim: restrictions on the use of synthetic antioxidant such as butylated hydroxyanisole (bha) and butylated hydroxytoluene (bht) are being imposed because of their carcinogecity . experimental: in this investigation, optimization of phenolic extraction process from methanolic (80%) extract (v/v) of  flomideschema parviflorum through response surface methodology by fulin cio-calt...

aim : to create an orthotopic hepatoma model with local metastasis monitored with ultrasound could be created as a platform for testing new treatments.   background : hepatoma accounts for 25% of liver tumors in children with poor overall survival. intraabdominal metastasis are present in 35% of patients at time of diagnosis.  we hypothesized that an orthotopic tumor model with local metastasis...

It is over several decades that ultrasound is used to enhance the transdermal drug delivery (phonphoresis). The mechanism of the enhancement is not fully understood and the ability of ultrasound on the enhancement for some drugs is unclear. The effect of continuous wave 870 KHz ultrasound at intensity of 1 W/cm 2 for 15 minutes on transdermal absorption of piroxicam from solution and gel formu...
