Effect of ultrasound on physicochemical and foaming properties of a protein concentrate from giant squid (Dosidicus gigas) mantle

Publication date: Available online 14 December 2019Source: LWTAuthor(s): Isabel Arredondo-Parada, Wilfrido Torres-Arreola, Guadalupe M. Suárez-Jiménez, Juan C. Ramírez-Suárez, Josué E. Juárez-Onofre, Francisco Rodríguez-Félix, E. Marquez-RiosAbstractGiant squid (Dosidicus gigas) proteins have appropriate functional properties, albeit of smaller magnitude in comparison to other marine species. Therefore, this research characterizes the ultrasound-induced (20 kHz; 20 and 40% amplitude; 0, 1, 3 and 5 min) changes to the physicochemical and foaming properties of mantle proteins. The changes in pH, electrophoretic profile, viscosity, surface hydrophobicity, particle size and zeta potential, as well as foaming capacity and stability were evaluated. A slight decrease (p ≥ 0.05) in the pH occurred as the ultrasound time increased. While no changes in SDS-PAGE (reducing and non-reducing) were detected, native PAGE revealed new bands. Ultrasound increased the viscosity and surface hydrophobicity, and decreased the particle size and net surface charge. Moreover, foaming capacity was improved and foaming stability was maintained at 100% for 1 h. Therefore, the application of ultrasound represents an alternative to improve the foaming properties.

Abstract Background: Historically, Iceland has been an iodine-sufficient nation due to notably high fish and milk consumption. Recent data suggest that the intake of these important dietary sources of iodine has decreased considerably. Objective: To evaluate the iodine status of pregnant women in Iceland and to determine dietary factors associated with risk for deficiency. Methods: Subjects were women (n = 983; 73% of the eligible sample) attending their first ultrasound appointment in gestational weeks 11-14 in the period October 2017-March 2018. Spot urine samples were collected for assessment of urina...

We report the case of a 6-year-old girl who presented with generalized abdominal pain and flu-like symptoms. Blood tests and AUS revealed typical findings of AP and a nasopharyngeal aspirate was positive for IVA. Twenty-four hours later, the patient developed signs of acute appendicitis, which was also confirmed by AUS. This case highlights the importance of AUS in the management of acute abdominal conditions in children, including reactive entities such as appendicitis, as well as the need to consider IVA as a potential causal agent of AP.

CONCLUSIONS: Injections of biostimulators deeper than the calculated values might result in reduced efficacy as the superficial fascial system is not targeted and the effected collagen neogenesis does not affect the skin surface.

CONCLUSION: High frequency monopolar radiofrequency device produced consistent and statistically significant fat thickness reduction from a single 60-minute treatment session, with minimal discomfort and no demonstrated side effects. Results are comparable to other hypo- and hyper-thermic fat treatment technologies.

BoussonAbstractDactylitis refers to a global swelling of a finger or a toe giving it a clinical sausage-shape presentation. It is an extremely suggestive symptom as it guides the rheumatologist towards a shortlist of diagnoses. However, radiologists are less familiar with dactylitis. The aim of this review is to detail and illustrate the main causes of dactylitis using standard X-ray imaging, ultrasound, computed tomography and magnetic reso...
