Exempel på hur man kan använda MICROBUBBLES i en mening

• Research questions investigated by students during courses and their thesis work at the Laboratory included: What are the effects of the natural light gradient on predator-prey interactions? How can the predator best see the prey without being seen? How does the focussing of small waves oscillating light regime influence camouflage and attack strategy? What are the influences of the different frequencies of microturbulences? How do such effects change at the moment when herring larvae join into schools? What role does the phenomenon of aggregation play? Do ocean physics create or alter organism-aggregations? Can the dynamics of aggregations effect ocean physics at the microscales? Are there effects of the surface waves? What are the distribution and dynamics of microbubbles caused by turbulences and gas-oversaturations? How can the organisms orient in respect to micro-gradients of the ocean physics? How do they survive in the direct vicinity of undulating anoxia and hypoxia? Why are eelpouts, sticklebacks and herrings so extremely successful in the Baltic while cod is not? What are the effects and functions of schooling for feeding and microscale-orientation? What is the behavior of fish in netcages and how much food is lost from the cages.
• Octafluoropropane microbubbles reflect sound waves well and are used to improve the ultrasound signal backscatter.
• Coalescence of ultrasound contrast agent microbubbles is studied to prevent embolies or to block tumour vessels.
• Sonoporation is the transient permeation of cell membranes assisted by ultrasound, typically in the presence of gas microbubbles.
• It has several biomedical applications including: propellant for pressurized metered dose inhalers; gas core in microbubble ultrasound contrast agents; and occlusion therapy via the conversion of nanometer liquid droplets into micrometer sized gas microbubbles (acoustic droplet vaporization).
• Sonodynamic therapy can be used synergistically with other therapeutic methods such as drug-loaded microbubbles, nanoparticles, exosomes, liposomes, and genes for improved efficacy.
• Although most ultrasound contrast agents take the form of microbubbles, other types exist, such as perfluorocarbon nanoparticles or echogenic liposomes.
• By injecting microbubbles into the blood before sonication, they found the intensities required to disrupt the BBB were two times lower than the intensity required with FUS alone.
• One technique uses MRI-guided FUS sonication of microbubbles to increase BBB permeability and allow GBM tumor biomarkers (EGFRvIII and TERT C228T) to pass the BBB and enter the plasma.
• For instance, ultrasound-based contrast media, such as microbubbles, can accumulate in hypervascularized tissues and release the active ingredient in response to ultrasound waves, thus targeting a specific area chosen by the sonographer.
• Essentially, if a series of localizations are close enough to one another in some limited number of successive frames, those localizations can be assumed to be the same microbubble along a certain path, and the path of those microbubbles may be interpolated from the data.
