Epilepsia, 2005 Summary: The immature brain is highly susceptible to seizures. The heightened susceptibility to seizures appears to be due, at least in part, to developmental changes that skew the balance between excitatory and inhibitory neurotransmitter systems in the brain in favor of a state of excitation.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

On an analog of the M.G. Krein theorem for measurable operators
Учёные записки Казанского университета: Серия Физико-математические науки, 2018 Let M be a von Neumann algebra of operators on a Hilbert space H and τ be a faithful normal semifinite trace on M. Let μt(T), t > 0, be a rearrangement of a τ-measurable operator T. Let us consider a τ-measurable operator A, such that μt(A) > 0 for all t

Rearrangement of cluster structure during fission processes
, 2003 Results of molecular dynamics simulations of fission reactions $Na_{10}^{2+} \to Na_7^+ + Na_3^+$ and $Na_{18}^{2+} \to 2 Na_9^+$ are presented. Dependence of the fission barriers on isomer structure of the parent cluster is analyzed.

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Rearrangements of dicarba-nido-undecaborates
Тонкие химические технологии, 2011 The thermal and chemically initiated thermal rearrangements of dicarba-nido-undecaborates was explored by computational chemistry. It was shown that the kinetic stability of dianions of these compounds is reduced in the series 2,9 > 7,8 > 1,7 > ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Next-Generation Sequencing Technologies for Early-Stage Cutaneous T-Cell Lymphoma
Frontiers in Medicine, 2019 The diagnosis of early stage cutaneous T-cell lymphoma is often difficult, particularly in mycosis fungoides (MF), because the clinical presentation, histological findings, and laboratory findings of MF resemble those of inflammatory skin diseases such ...
