Could 37 degrees C storage temperature extend homovital valve allograft viability?
Storage at 37 degrees C significantly improved valve allograft cell metabolic activity and viability compared with storage at 4 degrees C for up to 14 days. The lower concentration of antibiotics did not affect the sterility of tissues stored at 37 degrees C.
RAMOS noninvasively determines the OTR as a measure of the metabolic activity of plant cells. Chemical enhancement of oxygen consumption by salicylic derivatives in parsley cell suspension cultures correlates with the induction of the primed state of enhanced defense that enhances the quantity of Pep13-induced furanocoumarin phytoalexins. Treatment with the priming-active compounds methyl jasmonate and pyraclostrobin also resulted in an enhanced respiration activity. Thus, RAMOS is a novel technology for identifying priming-inducing compounds for agriculture.
