The effect of ultra-sonication on quality characteristics and flavor of baked eggs was studied. One hundred and twenty eggs were cooked and assigned to six treatments groups (n=20 each) that were then soaked in saline solution at various concentrations (5, 10 and 18%) with/or without further ultra-sonication treatment at 35 kHz for 1 h. The pH values were lower in the ultra-sonicated samples in...

Introduction : When treating periprosthetic joint infection with a two-stage procedure, antibiotic-impregnated spacers can be used in the interval between prosthetic removal and reimplantation. In our experience, cultures of sonicated spacers are most often negative. The objective of the study was to assess whether that sonication causes an elution of antibiotics, leading to elevated antibiotic...

abstractbackground : in order to quantify effects of ultrasound irradiation parameters under therapeutic condition, especially sonodynamic therapy, it is initially necessary to evaluate inertial cavitation activity in vitro conditions therefore, in this study, the effect of 1 mhz low level ultrasound based on °oh radicals generated by acoustic inertial cavitation in aqueous solution was monitor...

Groundwater is one of our most valuable natural resource. More than 50% of the U.S. population depends on groundwater for domestic use and more than 95% of the rural population is dependent on groundwater. A major portion of industries and agriculture use groundwater. These numbers suggest that the personal and economic health of the nation is dependent on groundwater. Contamination of groundwa...

Banana blossom is a source of anthocyanin that potentially utilized as natural dyes in the food industry. Anthocyanin from banana can be extracted using Ultrasonic Assisted Extraction (UAE) and maceration method. ultrasonic causes cavitation effect thereby provide an efficiency extraction time if compared with This study aimed to determine duration sonication treatment on total extract. Experim...

PURPOSE We evaluated the delivery efficiency of intravenously injected large molecular agents, before and after disruption of the blood-brain barrier (BBB-D), induced by focused ultrasound (FUS) using various acoustic parameters. MATERIALS AND METHODS Male Sprague-Dawley rats were injected intravenously with Evans blue (EB) before or after BBB-D induction by pulsed FUS. We used a 1.0 MHz puls...

Isolated murein sacculi of Escherichia coli PA3092 were physically ruptured by sonication. Electron microscopical analysis showed that the rupturing occurred preferentially prependicular to the long axis of the cell. The fragmentation of the sacculi increased with longer sonication times. It was found that the extent of cross-linkage was more affected by the sonication than was the average glyc...

Microalgae are a promising feedstock for biofuels because of their capability to produce lipids. Cell disruption is necessary to maximize lipid extraction. Sonication conditions were evaluated for breaking heterotrophic (Schizochytrium limacinum) and autotrophic (Chlamydomonas reinhardtii) microalgae cells. Cell disruption was estimated by Nile red-lipids fluorescence quantification in S. limac...
