Three-dimensional architecture of actin filaments in Listeria monocytogenes comet tails. [PDF]
Proc Natl Acad Sci U S A, 2013 The intracellular bacterial pathogen Listeria monocytogenes is capable of remodelling the actin cytoskeleton of its host cells such that "comet tails" are assembled powering its movement within cells and enabling cell-to-cell spread.

Investigating the Composition of Listeria actin Comet Tails [PDF]
, 2022 Several intracellular bacterial pathogens, including Listeria monocytogenes (Lm), can colonizethe cytosol of host cells during infection. Cytosolic Lm then hijacks the host cells’ actin polymerization machinery using ActA to recruit the host Arp2/3 ...

Assessing the genotoxicity of oral titanium dioxide nanoparticle administration in male rats using micronuclei and comet assay [PDF]
Fayoum Journal of Agricultural Research and Development, 2023 This study evaluated the toxic effects of titanium dioxide (TiO2) nanoparticles (NPs) on rats that received oral administration of TiO2-NPs with a particle size of 15±2nm once daily at doses of 0, 50, 100, 150, 200, and 300mg/kg for ten weeks.

Nature, 1870 IN NATURE of 16th December, Prof. Tait advances the opinion that the tail of a comet consists of nothing but meteorites; mentioning in proof of this that the orbits of the August and November meteors have been determined, and found to be identical with those of two known comets. I do not question the importance of this most remarkable fact, but I think

Stochastic modeling for the COMET-assay [PDF]
, 2003 We present a stochastic model for single cell gel electrophoresis (COMET-assay) data. Essential is the use of point process structures, renewal theory and reduction to intensity histograms for further data ...

Measuring Physical Properties at the Surface of a Comet Nucleus [PDF]
, 2021 The European Space Agency’s cornerstone mission Rosetta is due for launch in January 2003. It will perform a rendezvous with comet 46P/Wirtanen beyond 3 AU and, following an initial mapping phase, deploy a lander to a selected site on the nucleus surface.

Genotoxicity of nitroso compounds and sodium dichromate in a model combining organ cultures of human nasal epithelia and the comet assay [PDF]
, 2001 Genotoxic effects of xenobiotics are a possible step in tumor initiation in the mucosa of the upper aerodigestive tract. Using the comet assay, detecting genotoxicity in human tissue has been restricted to single incubations in vitro, but in vivo most ...

Actin filament attachments for sustained motility in vitro are maintained by filament bundling. [PDF]
PLoS ONE, 2012 We reconstructed cellular motility in vitro from individual proteins to investigate how actin filaments are organized at the leading edge. Using total internal reflection fluorescence microscopy of actin filaments, we tested how profilin, Arp2/3, and ...
