OBJECTIVE Premature complexes (PCs) in the electrocardiogram (ECG) signal have been reported for myocardial contrast echocardiography and also for burst mode (physical therapy) ultrasound with gas body contrast agents at lower peak rarefactional pressure amplitudes (PRPAs). For contrast echocardiography, irreversibly injured cardiomyocytes have been associated with the arrhythmia. The objective...

The aim of this study is to investigate the application ultrasound in extraction betanin from beets (Beta vulgaris) using Deep eutectic solvents (DES). process was optimized response surface methodology. time variable found be correlated with performance. Three DES (choline chloride: urea (CC:U), choline glycerol (CC:G), and citric acid (CC:Ac)) were studied. concentration extracted CC:U, CC:G,...

Phytochemicals from tropical fruits and their by-products have shown the potential to use as antimicrobial natural. This study aimed optimize recovery of phenolic compounds (total polyphenols flavonoids) cashew apple using ultrasound-assisted extraction promote functional attributes its coproducts evaluate antioxidant potential. An experimental design applying a response surface methodology was...

This work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. One application of nanotechnology is in improvement of available treatments for various diseases. Deferasirox (ICL670 or Exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. In the present work, deferasirox was prepared in nano size...

Indwelling prostheses and subcutaneous delivery devices are now routinely and indispensably employed in medical practice. However, these same devices often provide a highly suitable surface for bacterial adhesion and colonization, resulting in the formation of complex, differentiated, and structured communities known as biofilms. The University of Washington Engineered Biomaterials group has de...

The feasibility of indirect application of low frequency ultrasound for demulsification of crude oil was investigated without using chemical demulsifiers. Experiments were performed in an ultrasonic bath with frequency of 35 kHz. Synthetic emulsions with water content of 12%, 35% and 50% and median of droplet size distribution (DSD), median D(0.5), of 5, 10 and 25 μm were prepared from crude oi...

Immersion protocols have been unsuccessful in consistently producing all-male tilapia at a high enough ratio for them to be commercially viable. This study explored ultrasound to improve on the results of previous immersion studies. Experiments were carried out to evaluate immersion with ultrasound as a sex-reversal procedure by 1) assessing duration of treatment (one vs. two hours) on the effi...

This article deals with two of the major steps involved in phospholipid synthesis: the preparation of the optically pure precursors, sn-glycero-3-phosphocholine (GPC) and -ethanolamine, from a convenient lipid source such as egg yolk, and acylation of hydroxyl groups present in those precursors involving an acid to yield the corresponding phospholipid. Phosphatidylcholines and phosphatidylethan...
