Effect of Imidocarb Application on Oxidative DNA Damage Caused by Anaplasmosis
Turkish Journal of Agriculture: Food Science and Technology, 2021 This study was aimed to evaluate DNA fragmentation by using Comet assay in naturally infected sheep with Anaplasmosis before and after treatment with the Comet method, which shows DNA damage specifically.

The unusual volatile composition of the Halley-type comet 8P/Tuttle: Addressing the existence of an Inner Oort Cloud [PDF]
Astrophys.J.683:L71-L74,2008, 2008 We measured organic volatiles (CH4, CH3OH, C2H6, H2CO), CO, and water in comet 8P/Tuttle, a comet from the Oort cloud reservoir now in a short-period Halley-type orbit. We compare its composition with two other comets in Halley-type orbits, and with comets of the "organics-normal" and "organics-depleted" classes.

Nano‐Topography Enhanced Topological‐Cell‐Analysis in Radiation‐Therapy
Advanced Healthcare Materials, EarlyView.Radiotherapy, a treatment that implies exposition of cells to radiation, offers promise to treat cancer. Here, it is hypothesized that the nanoscale details of a scaffold can amplify the response of cells to radiation, measured through topological variables, providing ways to assess the efficacy of Radiotherapy treatment.

Comet 12P/Pons-Brooks: Identification with Comets C/1385 U1 and C/1457 A1 [PDF]
arXiv, 2020 Comet 12P/Pons-Brooks is an intermediate-period comet (orbital period around 71 years) comparable to 1P/Halley. The comet was seen first in 1812, and then again in 1883 and 1954. The comet was recovered in 2020 an will pass its perihelion passage 2024. We report the unambiguous identification of this comet with the historic comets C/1385 U1 and C/1457 ...

Photometry of comet C/2011 L4 (PANSTARRS) at 4.4 - 4.2 AU heliocentric distances [PDF]
published in Icarus Note, 2014, 2015 We present an analysis of the photometric data of comet C/2011 L4 (PANSTARRS) observed at heliocentric distance of 4.4 - 4.2 AU. The comet C/2011 L4 (PANSTARRS) shows one significant activity, despite of its quite large heliocentric distance. The color indexes, dust mass-loss rates and radius of the comet are measured.

Advanced Science, EarlyView.This study demonstrates that the resveratrol analogue, trans‐4,4′‐dihydroxystilbene (DHS), exhibits synergistic anti‐tumor activity with the PARP inhibitor talazoparib, inducing significant ovarian cancer cell death. The synergistic effect of this combination arises from the concurrent downregulation of homologous recombination factors and the ...

Systematic satellite observations of the impact of aerosols from passive volcanic degassing on local cloud properties [PDF]
Atmospheric Chemistry and Physics, 2014 The impact of volcanic emissions, especially from passive degassing and minor explosions, is a source of uncertainty in estimations of aerosol indirect effects.

RFWD3 Reprograms Nucleotide Metabolism Through PHGDH to Induce Chemoresistance In Osteosarcoma
Advanced Science, EarlyView.RFWD3 is identified as a key regulator of cisplatin (DDP) sensitivity in osteosarcoma using a genome‐wide CRISPR screen. RFWD3 promotes PHGDH ubiquitination, enhancing NAD+‐mediated nucleotide biosynthesis. Knocking out RFWD3 sensitized osteosarcoma cells to DDP.

Observing eruptions of gas-rich compressible magmas from space
Nature Communications, 2016 Satellite observations are an important tool in volcano monitoring, but observations such as ground deformation and gas emissions are treated independently. Here, the authors present a model coupling them through their link to magma volatile contents and
