Ionic liquid based, ultrasound-assisted extraction was successfully applied to the extraction of phenolcarboxylic acids, carnosic acid and rosmarinic acid, from Rosmarinus officinalis. Eight ionic liquids, with different cations and anions, were investigated in this work and [C(8)mim]Br was selected as the optimal solvent. Ultrasound extraction parameters, including soaking time, solid-liquid r...

BACKGROUND Real time ultrasound guided percutaneous kidney biopsy has become the standard procedure to assess the pathology of native kidneys and renal transplants. No specific technique has shown to be totally free of post biopsy bleeding complications. Few Studies have looked at the rates of post biopsy bleeding complications comparing different needle size, post biopsy haematoma size, or cli...

Debridement takes away nonvascularised tissue and cells that may obstruct wound contraction, the formation of granulation tissue and the migration of epithelial cells from the wound edge (Falanga, 2000) to create This article describes a new type of mechanical debridement that uses lowfrequency ultrasound technology, and presents case reports that highlight the use of the Sonoca® (Soring) ultra...

Effect of ultrasound assisted extraction’s condition on degumming process and investigation quality parameters soybean oil

Curcumin is the natural bio-active component of turmeric (Curcuma longa L.) with known therapeutic properties; nevertheless, its biological applications are limited due to its poor bioavailability. To overcome this limitation, curcumin was conjugated with silica nanoparticles. Curcumin was separated from turmeric by microwave-assisted extraction and silica nanoparticles were developed from rice...

INTRODUCTION Vacuum-assisted core biopsy (VACB) guided by ultrasound is a minimally invasive method used in diagnosis and treatment of breast focal lesions. Vacuum-assisted core biopsy is an interesting minimally invasive alternative to open surgical biopsy. AIM To assess the value of ultrasound-guided vacuum-assisted core biopsy in the diagnosis and treatment of breast focal lesions. MATER...

Textile industry effluents contain reactive dyes that may harm our receiving waters. A typical reactive blue (RB) 19 dye is frequently detected in significant concentrations in textile industry effluents. Such dyes have generally shown resistance to decomposition and tend to persist in the environment for long periods and multiply the impacts to water and environment. Therefore, the present inv...

Ultrasound-assisted extraction (UAE) of phenolic compounds from Inula helenium was studied. Effects of ethanol concentration, ultrasonic time, solid-liquid ratio, and number of extractions were investigated. An orthogonal array was constructed to optimize UAE process. The optimized extraction conditions were as follows: ethanol concentration, 30%; solid-liquid ratio, 1 : 20; number of extractio...
