Single-Cell Point Constrictions for Reagent-Free High-Throughput Mechanical Lysis and Intact Nuclei Isolation

Micromachines, 2019
Highly localized (point) constrictions featuring a round geometry with ultra-sharp edges in silicon have been demonstrated for the reagent-free continuous-flow rapid mechanical lysis of mammalian cells on a single-cell basis. Silicon point constrictions,

Cutting out the middleman: measuring nuclear area in histopathology slides without segmentation

, 2016
The size of nuclei in histological preparations from excised breast tumors is predictive of patient outcome (large nuclei indicate poor outcome). Pathologists take into account nuclear size when performing breast cancer grading.

Accretion Disk Structure and Kinematics of the Broad Line Regions in Selected AGN

Open Astronomy, 2011
Broad emission line regions in AGN are connected with the outer layers of accretion disks. This has been shown by means of line variability studies of individual AGN as well as line profile studies of AGN samples.

Histochemical Evidence for Nitrogen-Transfer Endosymbiosis in Non-Photosynthetic Cells of Leaves and Inflorescence Bracts of Angiosperms

Biology, 2022
We used light and confocal microscopy to visualize bacteria in leaf and bract cells of more than 30 species in 18 families of seed plants. Through histochemical analysis, we detected hormones (including ethylene and nitric oxide), superoxide, and ...

Conditions for the formation of anomalous tail of comet

Open Astronomy, 2019
The time and velocity of ejection of dust particles of anomalous tails from cometary nuclei are determined. It is revealed that some comets cause the formation of an anomalous tail is the collision of their comet nucleus with other bodies of the Solar ...

The link between inhibition of PI3K signaling, induction of autophagy, and elimination of organelles to form the lens organelle-free zone

Autophagy Reports, 2022
The elimination of organelles to create the lens organelle-free zone (OFZ) is a macroautophagy/autophagy-dependent mechanism that occurs without causing cell death.
