The present study was conducted to evaluate the effect of ultrasound on functional properties citrus juices. Citrus fruits and juices were analyzed for physico-chemical properties. ‘Pamelo’ excelled in terms average fruit weight (451.83 ± 7.1 g), volume (543.33 9.1 cm3) rag percentage (68.64 1.1%). ‘Valencia late’ (48.67 0.3%), ‘Flame’ (48.38 1.3%) ‘Kinnow’ (35.95 4.9%) good juice %. subjected ...

The effects of cholesterol and Tween 80 on the physical stability of empty liposomes were investigated. Results showed that the physical stability of liposomes, including electrostatic and steric stability, was improved by addition of cholesterol and Tween 80. Liposomes prepared by different methods, thin-film hydration, thin-film sonication, reverse-phase evaporation and freeze-thawing, were t...

Background Mild hyperthermia (41.5-44°C) has been shown to enhance the effect of radiotherapy and chemotherapy. However, currently available heating methods are often inefficient in inducing conformal hyperthermia for deep seated targets. Here, the software of Philips Sonalleve V2 MR-HIFU system was modified to enable performing a long duration large volume hyperthermia sonication in in-vivo po...

This review is a survey on ultrasonic application in selected carbohydrate polymers based upon available research reports. It covers a brief discussion on the fundamentals of ultrasound technology, before delving on the effects of ultrasound on specific polymers; pectin, chitin, starch, carrageenan and guar gum, their modification products and possible applications in food, pharmaceutical, biom...

A method is demonstrated to prepare graphene dispersions at high concentrations, up to 1.2 mg mL(-1), with yields of up to 4 wt% monolayers. This process relies on low-power sonication for long times, up to 460 h. Transmission electron microscopy shows the sonication to reduce the flake size, with flake dimensions scaling as t(-1/2). However, the mean flake length remains above 1 microm for all...

Production of lipoic acid (LA) is undergoing a paradigm shift with significant preference for fermentative production over conventional chemical synthesis. However, low product yield triggers the importance of the development of an efficient cell disruption method as a critical step in its recovery. In this paper, we report screening of various physical, mechanical and chemical methods of cell ...

BACKGROUND Periprosthetic joint infection (PJI) is the most severe complication, following joint arthroplasty. Identification of the causal microbial factor is of paramount importance for the successful treatment. PURPOSE The aim of this study is to compare the sonication fluid cultures derived from joint prosthetic components with the respective periprosthetic tissue cultures. METHODS Expl...

Differentiating intracellular from extracellular enzyme activity is important in soil enzymology, but not easy. Here, we report on an adjusted sonication method for the separation of intracellular from extracellular phosphatase activity in soil. Under optimal sonication conditions [soil:water ratio  =  1/8 (w/v) and power density  =  15 watt ml(-1)], the activity of alkaline phosphomonoesterase...
