Comet assay - a sensitive tool for genotoxicity assessment of environmental stress in Mytilus galloprovincialis from the Bulgarian Black Sea coast [PDF]
BioDiscovery, 2017 Assessment of DNA damage is of primary concern when the pollution-related stress in living organisms has to be determined. The reason for this concern comes from the evidence that damages in DNA often lead to mutations which are potential threat for the ...

A common misunderstanding in lung ultrasound: the comet tail artefact.
Medical ultrasonography, 2018 The comet tail artefact is probably one of the most commonly and imprecisely used to describe vertical artefacts found in lung ultrasound. Two distinct artefacts are commonly observed: the lung comets and the B-lines. Both artefacts differ with regard to

DNA damage in buccal cells in oral PMDs and malignant disorders by comet assay
Brazilian Journal of Oral Sciences, 2019 Aim: DNA damage associated with Oral Squamous Cell Carcinoma (OSCC) and potentially malignant disorders (PMDs) is produced due to carcinogenic agents or increased oxidative stress. Comet assay can assist in early detection and evaluation of the amount of

The earliest drawings of datable auroras and a two-tail comet from the Syriac Chronicle of Zūqnīn [PDF]
, 2016 People have probably been watching the sky since the beginning of human history. Observers in pre-telescopic ages recorded anomalous events and these astronomical records in the historical documents provide uniquely valuable information for modern ...

Aging Cell, 2022 It is known that chondrocytes from joints with osteoarthritis (OA) exhibit high levels of DNA damage, but the degree to which chondrocytes accumulate DNA damage during “normal aging” has not been established.

Genes and Environment, 2022 Background In eye-drop drug development, the additional genotoxicity tests in some cases might be necessary to assess genotoxicity in the ocular surface since the ocular surface is exposed directly to high drug concentrations.

Effect of imidocarb on dna damage in sheep with babesiosis [PDF]
Kafkas Universitesi Veteriner Fakültesi Dergisi, 2022 In this study, it was aimed to determine the DNA damage using the comet assay, which specifically shows DNA damage in naturally Babesia spp.-infected sheep and to evaluate the damage before and after imidocarb application.

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

Light-curve analysis of KOI 2700b: the second extrasolar planet with a comet-like tail [PDF]
, 2017 The Kepler object KOI 2700b (KIC 8639908b) was discovered recently as the second exoplanet with a comet-like tail. It exhibits a distinctly asymmetric transit profile, likely indicative of the emission of dusty effluents and reminiscent of KIC 12557548b,
