Biogenic gas nanostructures as ultrasonic molecular reporters. [PDF]
, 2014 Ultrasound is among the most widely used non-invasive imaging modalities in biomedicine, but plays a surprisingly small role in molecular imaging due to a lack of suitable molecular reporters on the nanoscale.

Evolution of Phytoplankton in Relation to Their Physiological Traits
Journal of Marine Science and Engineering, 2022 Defining the physiological traits that characterise phytoplankton involves comparison with related organisms in benthic habitats. Comparison of survival time in darkness under natural conditions requires more information.

Extent and mechanism of sealing in transected giant axons of squid and earthworms [PDF]
, 1994 Transected axons are often assumed to seal at their cut ends by the formation of continuous membrane barriers that allow for the restoration of function in the axonal stumps.

An Investigation into the Recycling of Gas Vesicle Protein Derived from Collapsed Gas Vesicles [PDF]
Microbiology, 1984 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.

Gas Vesicle–Blood Interactions Enhance Ultrasound Imaging Contrast
Nano Letters, 2023 ABSTRACTGas vesicles (GVs) are genetically encoded, air-filled protein nanostructures of broad interest for biomedical research and clinical applications, acting as imaging and therapeutic agents for ultrasound, magnetic resonance, and optical techniques.

Spontaneous mutations in gas vesicle genes ofPlanktothrixspp. affect gas vesicle production and critical pressure [PDF]
FEMS Microbiology Letters, 2002 Wild-type strains of the cyanobacterium Planktothrix rubescens have a cluster of gas vesicle (gvp) genes with repeats of alternating gvpA and gvpC. The gvpC occurs in three length variants, all with the same 3'-sequence, OmegaC. Spontaneous non-buoyant mutants had lost some of the alternating gvpAC copies and their gvpC genes had a novel 3'-end ...

Analysis of Halobacterium halobium Gas Vesicles [PDF]
Journal of Bacteriology, 1973 Gas vesicles, isolated from lysed Halobacterium halobium cells, gave an amino acid analysis which accounted for 78% of the weight, and the balance was mainly salt and water. One percent of tightly bound d -galactose was found, as well as 2% of phosphate that was not released by treatment ...
