A review of high‐speed optical imaging technology for the analysis of ultrasound contrast agents in an acoustic field

open access: yesiRADIOLOGY, 2023
Stabilized microbubbles were commercialized over 30 years ago for use as contrast agents in ultrasound imaging. In recent years, interest in microbubble–acoustic interactions has expanded to applications not only in ultrasound imaging but also in drug ...

High Speed Lossless Image Compression

open access: yes, 2015
We introduce a simple approach to lossless image compression, which makes use of SIMD vectorization at every processing step to provide very high speed on modern CPUs. This is achieved by basing the compression on delta coding for prediction and bit packing for the actual compression, allowing a tuneable tradeoff between efficiency and speed, via the ...

High-speed Raman imaging of cellular processes [PDF]

open access: yesCurrent Opinion in Chemical Biology, 2016
Raman scattering microscopy provides information about the distribution and chemical state of molecules in live cells without any labeling or modification. In recent years, the imaging speed of Raman microscopy has improved greatly owing to the development of instruments that can perform parallel acquisition of Raman spectra from multiple points.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Dynamic ultra high speed Scheimpflug imaging for assessing corneal biomechanical properties

open access: yesRevista Brasileira de Oftalmologia, 2013
OBJECTIVE: To describe a novel technique for clinical characterization of corneal biomechanics using non-invasive dynamic imaging. METHODS: Corneal deformation response during non contact tonometry (NCT) is monitored by ultra-high-speed (UHS) photography.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
