Background: Persistent physical fatigue (PPhF) accompanying daily intensive training often results in underperformance. While salivary secretory immunoglobulin A (SIgA) has been traditionally used as an immunological marker, salivary human herpesvirus 6 and/or 7 (HHV-6/7) have recently been presented as "microbiological" markers of PPhF. This study aimed to examine the monthly variabilities of salivary HHV-6/7 levels and the difference with SIgA along the training periodization.

Article Synopsis
  • Autonomously replicating sequences (ARSs) are crucial for the replication and stability of episomal vectors in organisms, but no ARS information has previously been reported for diatoms.
  • In this study, researchers used chromatin immunoprecipitation sequencing to identify ARS candidates in the model diatom Phaeodactylum tricornutum, focusing on subunits ORC2 and ORC4, which bound to 355 genomic sites.
  • Of those, 69 sites showed consistent screening results, revealing that these ARS candidates have an AT-richness of about 50% and unique characteristics compared to ARSs in other eukaryotes, indicating a distinct nature in diatom ARSs.

Muscle regeneration depends on muscle stem cell (MuSC) activity. Myogenic regulatory factors, including myoblast determination protein 1 (MyoD), regulate the fate transition of MuSCs. However, the direct target of MYOD in the process is not completely clear.
