Nanosized Contrast Agents in Ultrasound Molecular Imaging
Applying nanosized ultrasound contrast agents (nUCAs) in molecular imaging has received considerable attention. nUCAs have been instrumental in ultrasound molecular imaging to enhance sensitivity, identification, and quantification.

A Genome-Scale Atlas Reveals Complex Interplay of Transcription and Translation in an Archaeon
The scale of post-transcriptional regulation and the implications of its interplay with other forms of regulation in environmental acclimation are underexplored for organisms of the domain Archaea.

Gas vesicle assembly in Microcyclus aquaticus [PDF]
When observed in the electron microscope intact gas vesicles appeared as transparent areas in whole cells of Microcylus aquaticus, whereas vesicles collapsed by centrifugation were not discernible. Within 5 min of suspending cells containing collapsed vesicles in growth medium, small transparent vesicles were detected.

Measuring gas vesicle dimensions by electron microscopy [PDF]
Abstract Gas vesicles (GVs) are cylindrical or spindle‐shaped protein nanostructures filled with air and used for flotation by various cyanobacteria, heterotrophic bacteria, and Archaea. Recently, GVs have gained interest in biotechnology applications due to their ability to serve as imaging agents and actuators for ultrasound ...

An Investigation into the Recycling of Gas Vesicle Protein Derived from Collapsed Gas Vesicles [PDF]
Gas vesicle protein may account for more than 6% of the cell dry weight and over 10% of the total cell protein in the planktonic cyanobacterium Anabaena Jlos-aquae. The gas vesicles collapsed by rising cell turgor pressure during buoyancy regulation can therefore represent a significant protein pool within this organism.

Cyanobacterial bloom is one of the most urgent global environmental issues, which eventually could threaten human health and safety. Sonication treatment (ST) is a potential effective method to control cyanobacteria blooms in the field.

The gas vesicle is a hollow structure made of protein. It usually has the form of a cylindrical tube closed by conical end caps. Gas vesicles occur in five phyla of the Bacteria and two groups of the Archaea, but they are mostly restricted to planktonic microorganisms, in which they provide buoyancy.

Gas vesicles and their application in biomedicine:
Gasvesikel sind gasgefüllte, intrazelluläre Nanostrukturen, die von einigen Mikroben als Schwebhilfe im wässrigen Milieu gebildet werden. Fotosynthetische Cyanobakterien und das extrem salzliebende Archaeon Halobacterium salinarum fottieren damit ...

Genetically encoded mediators for sonogenetics and their applications in neuromodulation
Sonogenetics is an emerging approach that harnesses ultrasound for the manipulation of genetically modified cells. The great penetrability of ultrasound waves enables the non-invasive application of external stimuli to deep tissues, particularly ...
