Solar Wind Interactions with Comet C/2021 A1 Using STEREO HI and a Data-assimilative Solar Wind Model

The Astrophysical Journal
Cometary tails display dynamic behavior attributed to interactions with solar wind structures. Consequently, comet-tail observations can serve as in situ solar wind monitors.

The Perihelion Emission of Comet C/2010 L5 (WISE) [PDF]

, 2017
The only Halley-type comet discovered by the Wide-Field Infrared Survey Explorer (WISE), C/2010 L5 (WISE), was imaged three times by WISE, and it showed a significant dust tail during the second and third visits (2010 June and July, respectively).

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 ...

Dust from Comet 209P/LINEAR during its 2014 Return: Parent Body of a New Meteor Shower, the May Camelopardalids [PDF]

, 2014
We report a new observation of the Jupiter-family comet 209P/LINEAR during its 2014 return. The comet is recognized as a dust source of a new meteor shower, the May Camelopardalids.

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

Reactive lymphoid hyperplasia of the liver: A case report featuring characteristic nodular and perinodular enhancement

Radiology Case Reports
A 53-year-old female with primary biliary cholangitis was referred for the evaluation of a hepatic nodule identified during routine imaging. Ultrasonography revealed a homogeneous, hypoechoic, 18 mm nodule in segment 3 of the liver. On dynamic CT and MRI,

Solar wind interaction with comet 67P: impacts of corotating interaction regions [PDF]

, 2016
International audienceWe present observations from the Rosetta Plasma Consortium of the effects of stormy solar wind on comet 67P/Churyumov-Gerasimenko. Four corotating interaction regions (CIRs), where the first event has possibly merged with a coronal ...

Genotoxicity study of Ethiopian medicinal plant extracts on HepG2 cells

BMC Complementary and Alternative Medicine, 2018
Background Most of herbal medicines are used without any standard safety and toxicological trials although common assumption is that these products are nontoxic. However, this assumption is incorrect and dangerous, so toxicological studies should be done
