One family member of the MAPKs, c-Jun N-terminal kinase 1 (JNK1), plays a key role in signal transduction via growth factors, cytokines and cellular stresses such as heat shock, UV radiation and ROS.
ERK1/2 is normally activated by growth signals [16], [17]; JNK1/2 and p38 respond to oxidative stress, heat shock, ionizing radiation, and UV light [18], [19], and are mainly associated with cell cycle arrest and apoptosis.
JNK is a stress-activated protein kinase that can be induced by inflammatory cytokines, bacterial endotoxin, osmotic shock, UV radiation, and so on.
A multitude of stresses has been demonstrated to modulate cellular SUMO modification dynamics, including heat shock, ionizing radiation, proteotoxicity, and bacterial infection.
In previous studies, the gene expression changes under normal Drosophila aging as well as after stress treatments including heat and cold shock, ionizing radiation exposure, oxidative stress (hyperoxia and hydrogen peroxide), heavy metal stress (cadmium, zinc, copper), and starvation were investigated using microarrays.
However, senescence can also be induced in the absence of detectable telomere loss or dysfunction by various cellular and environmental stressors, such as culture shock, ionizing radiation or prolonged exposure to substantial doses of oxidative stress, generally known as stress-induced premature senescence.
Approximately 85 percent of the explosive energy produces air blast (and shock) and thermal radiation (heat).
The iDEN device of course meets military specs for dust, shock vibration, solar radiation — pretty much anything Hal Jordan could manifest.
For each channel an RF-generator will be developed and subjected to a suite of environmental tests such as thermal-vacuum, vibration, radiation, shock and Electromagnetic Compatibility (EMC).
Advantages such as energy saving, low radiation, shock resistance, and spectral power tunability over fluorescent and incandescent light sources have propelled the commercialization of solid-state lighting devices containing semiconductors as the light emitters [72].
