Thromboelastographic evaluation in dogs with Asian pit viper (Gloydius) envenomation.

The objective of this study was to investigate the thromboelastography (TEG) variables and platelet count after Asian pit viper (Gloydius) envenomation in dogs compared with healthy control dogs. Ten dogs with snake envenomation and twenty healthy dogs were included. There was a significant decrease in G (P=0.

Core promoter activity contributes to chromatin-based regulation of internal cryptic promoters.

During RNA polymerase II (RNA Pol II) transcription, the chromatin structure undergoes dynamic changes, including opening and closing of the nucleosome to enhance transcription elongation and fidelity. These changes are mediated by transcription elongation factors, including Spt6, the FACT complex, and the Set2-Rpd3S HDAC pathway. These factors not only contribute to RNA Pol II elongation, reset the repressive chromatin structures after RNA Pol II has passed, thereby inhibiting aberrant transcription initiation from the internal cryptic promoters within gene bodies.
