Tau aggregates are RNA-protein assemblies that mislocalize multiple nuclear speckle components
Neuron, 2021 Tau aggregates contribute to neurodegenerative diseases including frontotemporal dementia and Alzheimer’s disease (AD). Although RNA promotes tau aggregation in vitro, whether tau aggregates in cells contain RNA is unknown. We demonstrate in cell culture

Singularities in speckled speckle: Statistics [PDF]
Optics Communications, 2008 Random optical fields with two widely different correlation lengths generate far field speckle spots that are themselves highly speckled. We call such patterns speckled speckle, and study their critical points (singularities and stationary points) using analytical theory and computer simulations.

Cold Spring Harbor Perspectives in Biology, 2010 Nuclear speckles, also known as interchromatin granule clusters, are nuclear domains enriched in pre-mRNA splicing factors, located in the interchromatin regions of the nucleoplasm of mammalian cells. When observed by immunofluorescence microscopy, they usually appear as 20-50 irregularly shaped structures that vary in size.

Non-Invasive Full Rheological Characterization via Combined Speckle and Brillouin Microscopy
IEEE Access, 2022 Rheology serves to measure the deformation and flow of materials. Its associated quantities, for example, the Young’s modulus, shear modulus, bulk modulus, or longitudinal modulus, are important in the biomedical field, in particular for soft ...

SON and SRRM2 are essential for nuclear speckle formation
eLife, 2020 Nuclear speckles (NS) are among the most prominent biomolecular condensates. Despite their prevalence, research on the function of NS is virtually restricted to colocalization analyses, since an organizing core, without which NS cannot form, remains ...

Journal of Medical Ultrasound, 2020 The "snowstorm" sign refers to the ultrasound appearance of motile hyperechoic specks within synovial fluid and has been reported to have a high specificity for gout. We describe three additional etiologies commonly encountered in the rheumatology clinic that can produce a snowstorm: calcium pyrophosphate deposition disease, fibrin collections/rice ...

A Contrast Calibration Protocol for X-ray Speckle Visibility Spectroscopy
Applied Sciences, 2021 X-ray free electron lasers, with their ultrashort highly coherent pulses, opened up the opportunity of probing ultrafast nano- and atomic-scale dynamics in amorphous and disordered material systems via speckle visibility spectroscopy.
