Molecular profiles of single circulating tumor cells from early breast cancer patients with different lymph node statuses

open access: yesThoracic Cancer, Volume 14, Issue 2, Page 156-167, January 2023., 2023
Circulating tumor cells (CTCs) were clustered into two subtypes significantly correlated with the lymph node metastasis status of early breast cancer patients. Patients with lymph node metastasis have CTCs that express an epithelial/stem‐like pattern of metastasis initiating cells, while those patients without lymph node metastasis have CTCs that have ...

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

Computed tomographic diagnosis of a fracture of the floor of the pelvis in a Thoroughbred foal

open access: yesEquine Veterinary Education, Volume 35, Issue 2, Page 82-86, February 2023., 2023
Summary This case report describes the clinical and diagnostic imaging findings, treatment and outcomes of a 15‐day‐old Thoroughbred foal referred for the evaluation of severe left hindlimb lameness of 8 days' duration. Radiographic examination of the left hindlimb and transcutaneous ultrasonographic examination of the pelvis were unremarkable.

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

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.

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 ...

Effect of imidocarb on dna damage in sheep with babesiosis [PDF]

open access: yesKafkas 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.

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.

The earliest drawings of datable auroras and a two-tail comet from the Syriac Chronicle of Zūqnīn [PDF]

open access: yes, 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 ...

Tails of Comets [PDF]

open access: yesNature, 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
