However unlike the intestinal stem cells which are constantly in active cell cycle to replenish gut epithelium in a fast turn-over mode (Clevers, 2013), the SOX9+ BCs in airway are quiescent most of the time, and could only be activated once a particular injury signal from more distal lung was received.
Regardless of the disparate mechanisms of senescent-inducing stresses, the senescence program is activated once a cell has sensed a critical level of damage or dysfunction.
LoJack features a hidden transmitter in the car, which is activated once a theft is reported.
The proteasome belongs to the family of threonine proteases and its maturation follows the concept of zymogen activation upon which proteases are activated, once they arrive at their destination.
In this view, EWS are conceived as more than alert systems that are activated once hazards are detected, but as a process that includes prehazard components such as risk education.
Found naturally on the surface of the cabbage, the micro-organisms are activated once the shredded leaves are massaged with salt, drawing out water to create its own brine.
In a study published Sept. 25 in Nature, a team led by Weill Cornell Medicine investigators Drs. Björn Kafsack and Olivier Elemento describe new genes that are activated once the parasite commits to transmission.
The deals are activated once enough people agree to buy online.
Thus, rat, mouse, and human TRPM8 are activated once temperatures drop below 26°C, such that the channel is closed at normal body temperature, but can respond with appropriate intensity to both innocuous and noxious cold stimuli [6], [7].
Although semiconductors of n-type, such as TiO2NTs, do not offer any potential electrochemical response at the anodic region, they can be "activated" once they are a priori subjected to a simple cathodic polarization (P-TiO2NTs) and used to follow the oxidation reaction without any other modification.
