  • Too much of a good thing: long-term treatment with salicylate strengthens outer hair cell function but impairs auditory neural activity. (cdc.gov)
  • Moreover, endosomal sorting complex required for transport (ESCRT)-related proteins and their transcripts are most abundant at early and mid-development. (nature.com)
  • Corresponding expression changes of these proteins at different developmental stages of female ticks are very important to ensure the orderly development of the organ. (biomedcentral.com)
  • Together with the other pathways, the UPR leads to a decrease in the protein folding load by causing a reduction in the general level of protein translation, and by inducing the expression of protein folding machinery. (helsinki.fi)
  • In 1979, of the four mechanisms of injury, age-adjusted mortality rates were highest for motor vehicle traffic deaths and lowest for drug poisoning deaths. (cdc.gov)
