Evaluation of DNA damage induced by perfluorooctanoic acid using acellular, cellular, and in vivo comet assays

Zhongguo shipin weisheng zazhi, 2023
ObjectiveTo examine perfluorooctanoic acid （PFOA）-induced DNA damage using a combined in vivo and in vitro experiment.MethodsAcellular nuclear DNA damage was used as a model to test the damage induced by exposure to 0.00， 0.13， 0.25， and 0.50 mmol/L PFOA

Data visualization and distinct features extraction of the comet Ison 2013

Iraqi Journal of Physics, 2019
The distribution of the intensity of the comet Ison C/2013 is studied by taking its histogram. This distribution reveals four distinct regions that related to the background, tail, coma and nucleus.

Combination of lung ultrasound (a comet-tail sign) and N-terminal pro-brain natriuretic peptide in differentiating acute heart failure from chronic obstructive pulmonary disease and asthma as cause of acute dyspnea in prehospital emergency setting

Critical Care, 2011
IntroductionWe studied the diagnostic accuracy of bedside lung ultrasound (the presence of a comet-tail sign), N-terminal pro-brain natriuretic peptide (NT-proBNP) and clinical assessment (according to the modified Boston criteria) in differentiating ...

Antitumoral Efficacy of AuNRs‐Laden ECFCs In Vitro and In Vivo: Decoding the Heat and Rays Combo Treatment in Breast Cancer and Melanoma Cells

Advanced Healthcare Materials, EarlyView.
Endothelial Colony Forming Cells (ECFCs) acted as cellular cyborgs, stealthily transporting gold nanorods (AuNRs) into tumors to enable targeted near‐infrared (NIR) hyperthermia combined with radiotherapy. This approach triggers ferroptosis in melanoma and inhibits autophagy in breast cancer, revealing a tumor‐specific response to nanomaterial‐assisted

Standardizing electrophoresis conditions: how to eliminate a major source of error in the comet assay.

Frontiers in Genetics, 2015
In the alkaline comet assay, cells are embedded in agarose, lysed, and then subjected to further processing including electrophoresis at high pH (>13). We observed very large variations of mean comet tail lengths of cell samples from the same population ...
