A common misunderstanding in lung ultrasound: the comet tail artefact.

open access: yesMedical 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

open access: yesBrazilian 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

Comet assay for quantification of the increased DNA damage burden in primary human chondrocytes with aging and osteoarthritis

open access: yesAging 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.

Estimation of the applied doses in irradiated anchovy and bluefish for shelf-life extension using image analysis in combination with DNA comet assay

open access: yesFood Materials Research, 2023
The objective of the present study was to estimate applied doses of irradiated anchovy (1.83−4.22 kGy) and bluefish (1.98−5.40 kGy) for shelf-life extension by using image analysis in combination with comet assay for trading irradiated fish, especially ...

Three Dimensional MHD Simulationof Comet Hale-Bopp Tail

open access: yesمجلة بغداد للعلوم, 2008
The interaction between comet Hale-Bopp tail with the solar wind is investigated in the present paper using magneto-hydrodynamic (MHD) numerical simulation, which accounts for the presence of the interplanetary magnetic field (IMF).

Time-course changes in DNA damage of corneal epithelial cells in rabbits following ocular instillation with genotoxic compounds

open access: yesGenes 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.
