A level-set based mesh adaptation technique for mass conservative ice accretion in unsteady simulations

This paper presents an innovative approach to model evolving boundaries problems due to the accumulation or erosion of material over a surface, offering a robust alternative to standard algebraic methods. The strategy is based on the level-set method and it allows the local conservation of the prescribed mass material accounting for the curvature of the body. No partial differential equations are solved for the level-set function, but simple geometric quantities are used to provide an implicit discretization of the new updated boundary. The method is applied to body-fitted unstructured grids, that allow a good representation of arbitrarily complex geometries. Two multi-step in-flight ice accretion simulations over a NACA0012 are presented to show the feasibility and adaptability of the method, that can be also extended to three-dimensional applications

Epigenetics and cortical spreading depression: changes of DNA methylation level at retrotransposon sequences

Cortical spreading depression (CSD) is an evolutionarily conserved phenomenon that involves a slow and self-propagating depolarization wave associated with spontaneous depression of electrical neuronal activity. CSD plays a central role in the pathophysiology of several brain diseases and is considered to be able to promote "Preconditioning". This phenomenon consists of the brain protecting itself against future injury by adaptation. Understanding of the molecular mechanisms underlying Preconditioning has significant clinical implications. We have already proposed that the long-lasting effects of CSD could be related to silencing of retrotransposon sequences by histone methylation. We analyzed DNA methylation of two retrotransposon sequences, LINE1 and L1, and their corresponding expression pattern after CSD induction. Based on immunoprecipitation assay of the methylated DNA (meDIP), we demonstrated hypermethylation of both sequences in preconditioned rat brain cortex compared with a control 24 h after CSD induction. Using quantitative PCR, we also showed that CSD induction caused a decrease of the transcript level of both retrotransposon sequences. Our data are consistent with the hypothesis of epigenetic modifications in Preconditioning-dependent neuroprotection by increasing genome stability via the silencing of retrotransposon sequences
