Predictions of the solar wind interaction with Comet Grigg-Skjellerup [PDF]
, 1992 The planned encounter of the Giotto spacecraft with comet Grigg-Skjellerup on 10th July 1992 promises to extend our knowledge of the solar wind interaction with comets substantially.

Advanced Science, EarlyView.Chromosome 16q loss drives genomic instability through disruption of the CYLD–TIRR–53BP1 axis. CYLD preserves homologous recombination by stabilizing TIRR and limiting 53BP1 accumulation at DNA double‐strand breaks. CYLD deficiency redirects repair toward error‐prone non‐homologous end joining, promotes mutational burden and homologous recombination ...

MED1, a novel binding partner of BRCA1, regulates homologous recombination and R-loop processing
Scientific Reports, 2022 Homologous recombination (HR) is a major repair pathway of DNA double-strand breaks and is closely related to carcinogenesis. HR deficiency has been established as a therapeutic target.

Advanced Science, EarlyView.Macrophage RSAD2 dually regulates CMPK2—the rate‐limiting enzyme for mitochondrial DNA synthesis—by suppressing its ubiquitination and promoting its phosphorylation via Csnk2a2 recruitment. This amplifies mtDNA production, which simultaneously activates a cGAS‐STING‐IRF3‐RSAD2 feedforward loop and the NLRP3 inflammasome, driving a self‐sustaining ...

Assessment of Cellular Damage by Comet Assay After Photodynamic Therapy in vitro
Acta Medica, 2004 The aim of this study was analysis of DNA damage in the cell line of the human melanoma G361 after photodynamic therapy (PDT) by comet assay. Photodynamic therapy is based on cytotoxic action of sensitizers (10 µM ZnTPPS4 fixed into 1 mM cyclodextrin ...

Exocomets size distribution in the $$\beta$$ β Pictoris planetary system
Scientific Reports, 2022 The star $$\beta$$ β Pictoris harbors a young planetary system of about 20 million years old, which is characterized by the presence of a gaseous and dusty debris disk, at least two massive planets and many minor bodies.

The wind-sock theory of comet tails [PDF]
, 1976 A method is reported for calculating the shapes of ionic comet tails that use the magnetic field along the tail to channel the tail plasma. The local momentum field in the solar wind determines magnetic field line locations along the tail.
