Comparison of comet assay parameters for estimation of genotoxicity by sum of ranking differences [PDF]
, 2013 Genotoxic potential of waters in six rivers and reservoirs from Serbia was monitored in different tissues of chub (Squalius cephalus L. 1758) with the alkaline comet assay.

Journal of Clinical Ultrasound, EarlyView.Our findings are given the increasing application of AI in medical imaging and the clinical necessity to improve the accuracy of thyroid nodule evaluation. The majority voting system combining C‐TIRADS, CEUS, and AI real‐time ultrasound‐assisted diagnosis achieved the highest diagnostic performance, with a sensitivity of 97% and specificity of 89 ...

Detection of Hypoxia in Human Brain Tumor Xenografts Using a Modified Comet Assay
Neoplasia: An International Journal for Oncology Research, 2003 We used the standard comet assay successfully to generate in vitro dose-response curves under oxic and hypoxic conditions. We then made mixtures of cells that had been irradiated with 3 and 9 Gy of X-rays to simulate two subpopulations in a tumor, but ...

Pulmonary scan in evaluating alveolar-interstitial syndrome in ER
Emergency Care Journal, 2006 Diffuse comet-tail artifacts at lung ultrasound are due to thickened interlobular septa and extravascular lung water. This condition is typical of the alveolar-interstitial syndrome due to pulmonary edema, diffuse parenchymal lung disease or ARDS. Aim of

Strong CO$^+$ and N$_2^+$ Emission in Comet C/2016 R2 (Pan-STARRS) [PDF]
ApJ Letters 854, L10, 2018, 2018 We report on imaging and spectroscopic observations of comet C/2016~R2 (Pan-STARRS) obtained with the 0.8\,m and 2.7\,m telescopes of McDonald Observatory in November and December 2017 respectively. The comet was at a heliocentric distance greater than 3\,{\sc au} during both sets of observations. The images showed a well-developed tail with properties

Prospects for the Crossing by Earth of Comet C/2023 A3 Tsuchinshan-ATLAS's Ion Tail [PDF]
The Earth will pass approximately downstream of the previous position of comet C/2023 A3 (Tsuchinshan-ATLAS) during 2024 October 10-13. We predict that spacecraft at the Sun-Earth Lagrange Point 1, L1, have a significant likelihood to detect pickup ions from the comet, as well as changes in the solar wind associated with the crossing of the comet's ion

physica status solidi (b), EarlyView.Novel Cu–Ni–Sn–S nanocrystals (NCs) stabilized with thioglycolic acid are synthesized in aqueous solutions. The structural and optical properties of Cu–Ni–Sn–S NCs are examined in colloidal solutions and thin films and compared to those of Cu–Zn–Sn–S NCs. The absorption coefficient is α > 104 cm−1 at 400 nm with an estimated Eg≈2.2 eV.

Are 2I/Borisov and Oort Cloud Comets Alike? [PDF]
arXiv, 2019 The interstellar comet 2I/Borisov bears a strong resemblance to Oort Cloud comets, judging from its appearance in images taken over the first six weeks of observation. To test the proposed affinity in more diagnostic terms, 2I is compared to Oort Cloud comets of similar perihelion distance, near 2 AU.
