Regulation of translation initiation following stress [PDF]

open access: yesOncogene, 1999
Recent studies suggest that genotoxic and non-genotoxic stresses appear to invoke translational checkpoints in order to inhibit protein synthesis. Depending on the stress and/or cell type, this downregulation of protein synthesis may either (i) protect against the deleterious effects of noxious agents and ensure the conservation of resources that are ...

Thermoelastic Model with Higher-order Time-derivatives and Two Phase-lags for an Infinitely Long Cylinder under Initial Stress and Heat Source [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2021
In this work, a generalized higher-order time-derivatives model with phase-lags has been introduced. This model is applied to study the thermal heat problem of a homogeneous and isotropic long cylinder due to initial stress and heat source.
