Soaking up stress
Text by Rabiya S. Tuma [email protected] Soaking up stress O n page 115, Ku and Omary add one more function to keratin’s expanding repertoire. In addition to acting as a structural protein in liver cells, keratin 8 (K8) apparently absorbs excess phosphorylation during stress and thus reduces the likelihood of apoptosis. Humans who carry a G61C polymorphism in K8 are predisposed to liver disease w...
متن کاملProblem solving by soaking the concept network
Because of the complexity and fuzziness of the real world, it’s hard to build a dense knowledge system and reason in it with traditional methods. But man can deal with such tasks freely. Inspired by cognition and linguistics, a solution is advanced for reasoning dense knowledge in this paper. Objects and concepts are organized in the form of concept graph. Soaking the nodes in the graph until t...
متن کاملDoubling up on cellular stress
Ino80 tidies up after DNA repair L ike a surgeon stitching up an incision after an operation, cells restore their chromatin after repairing DNA damage. Sarkar et al. identify a protein that helps put the chromatin back in order. When UV light zaps DNA, the nucleotide excision repair apparatus swings into action, cutting out and replacing the damaged section. Before the work can begin, however, ...
متن کاملStructural disorder induced in hydrogenated amorphous silicon by light soaking
We show, using variable coherence transmission electron microscopy, that light soaking of amorphous hydrogenated silicon thin films leads to structural changes. We speculate that the structural changes are associated with instability in the as-deposited material. We suggest that improved immunity to Staebler–Wronski degradation could be achieved by a less-ordered material which is closer to the...
متن کاملDelignification Kinetics of Corn Stover with Aqueous Ammonia Soaking Pretreatment
Soaking aqueous ammonia (SAA) pretreatment of corn stover was carried out at three temperatures (30, 50, and 70 oC) and three concentrations of ammonia solution (5, 15, and 25 wt.%). The delignification kinetic model, based on three first-order reactions, was applied to describe the kinetic behavior of lignin removal from corn stover during SAA pretreatment. The first, second, and third terms w...
