Ultrasound-involved emerging strategies for controlling foodborne microbial biofilms
Publication date: Available online 19 December 2019Source: Trends in Food Science &TechnologyAuthor(s): Hang Yu, Yang Liu, Lu Li, Yahui Guo, Yunfei Xie, Yuliang Cheng, Weirong YaoStructured abstractsBackgroundPollution of foodborne microbial biofilms is a serious problem in the food industry. Microorganisms in the biofilms become insensitive to environmental stresses and increase tolerance to antimicrobial agents, therefore, making them extremely hard to be inactivated by conventional methods. Ultrasound-involved emerging strategies offer options for effectively controlling the biofilms formed on either food contact surfaces or real foods.Scope and approachThis review emphasizes the significances of either ultrasonication alone or combined with other strategies for controlling foodborne microbial biofilms.Key findings and conclusionsUltrasound as an emerging technology would effectively destroy biofilm structure and partially inactivate microorganisms in the biofilms; however, stimulated the growth of microbes may happen after treatment of low-frequency and low-intensity ultrasound. Combined ultrasound (especially low-frequency and high-intensity ultrasound) and chemical disinfectants shows a synergistic effect with a relatively high proportion of inactivated microbes in the biofilms compared with that adopted one strategy alone. Ozone and electrolyzed water are also developed for inactivating microbes and removing the biofilms after combining with the ultrasound. Combine...

CONCLUSION: In this study, we found a strong correlation between ScvO2 and NIRS measurements taken from the internal jugular vein site. Accordingly, continuous noninvasive monitoring with transcutaneous NIRSijv can be an alternative method as a trend monitor for the central venous oxygen saturation in pediatric cardiac patients undergoing congenital cardiac surgery.

AbstractPurposeRobot-assisted laparoscopic radical prostatectomy (RALRP) using the da Vinci surgical robot is a common treatment for organ-confined prostate cancer. Augmented reality (AR) can help during RALRP by showing the surgeon the location of anatomical structures and tumors from preoperative imaging. Previously, we proposed hand-eye and camera intrinsic matrix estimation procedures that can be carried out with conventional instruments within the patient during surgery, take
Authors: Piłat P, Borzęcki A, Jazienicki M, Gerkowicz A, Szubstarski F, Krasowska D Abstract Introduction: There are many papers in the available literature on the pre-operative evaluation of malignant melanoma (MM) using a 20 MHz probe. In many Western European countries, this examination is standard in the diagnosis of such lesions in terms of the resection margin. However, few papers describe and compare the results of melanoma thickness measurements using 20 and 50 MHz frequency probes. Aim: The aim of the study was to evaluate the thickness of melanoma using 20 and 50 MHz probes. In addition, the obtaine...
CONCLUSIONS: As the tibial nerve and its branches presents a huge variability in the medial ankle area in order to prevent the iatrogenic injuries the preoperative or intraoperative ultrasound assessment (sonosurgery) of its localization should be introduced into the clinic.

Authors: Parker KJ, Poul SS Abstract After 100 years of theoretical treatment of speckle patterns from coherent illumination, there remain some open questions about the nature of ultrasound speckle from soft vascularized tissues. A recent hypothesis is that the fractal branching vasculature is responsible for the dominant echo pattern from organs such as the liver. In that case, an analysis of cylindrical scattering structures arranged across a power law distribution of sizes is warranted. Using a simple model of echo strength and basic transformation rules from probability, we derive the first order statist...
