The RpoS sigma factor protein of Escherichia coli RNA polymerase is the master transcriptional regulator of physiological responses to a variety of stresses.This stress response comes at the expense of scavenging for scarce resources, causing a trade-off between stress tolerance and nutrient acquisition.This trade-off favors non-functional rpoS all
The Fukushima accident reveals the vulnerability of existing active nuclear power plant (NPP) design against prolonged loss of external electricity events.The passive safety system is considered an attractive alternative to cope with this kind of disaster.Also, the passive safety system enhances both the safety and the economics of NPPs.The adoptio
Periodontitis is a chronic, destructive disease of periodontal tissues caused by multifaceted, dynamic interactions.Periodontal bacteria and host immunity jointly contribute to the pathological processes of the disease.The dysbiotic microbial communities elicit an excessive immune response, mainly by polymorphonuclear neutrophils (PMNs).As one of t
The protein kinase Mec1 (ATR ortholog) and its partner Ddc2 (ATRIP ortholog) play a uunipelti key role in DNA damage checkpoint responses in budding yeast.Previous studies have established the model in which Ddc1, a subunit of the checkpoint clamp, and Dpb11, related to TopBP1, activate Mec1 directly and control DNA damage checkpoint responses at G
