Local Structure of Superionic Glass Agx(GeSe3)1-x, x=0.565

EPJ Web of Conferences, 2011
To investigate relation between inhomogeneous structure of Agx(GeSe3)1-x superionic glass and conduction path formation, x-ray diffraction, neutron diffraction and EXAFS measurements on K-edges for each constituent were performed.

Gate Drive Circuit Suitable for a GaN Gate Injection Transistor

IEEE Access, 2023
A GaN gate injection transistor (GIT) has great potential as a power semiconductor device. However, a GaN GIT has a diode characteristic at the gate-source, and a corresponding gate drive circuit is thus required.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

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 ...

Conduction mechanisms of the reverse leakage current of β-Ga2O3 Schottky barrier diodes

Semiconductor Physics, Quantum Electronics & Optoelectronics, 2019
In order to determine the temperature dependence of the reverse transition voltage between thermionic emission and tunneling mechanisms, a numerical method has been applied for β-Ga2O3 Schottky barrier diodes. The main idea of this method is based on the

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Dynamics of atrioventricular nodal conduction ratios of reverse alternating Wenckebach periods [PDF]

, 1989
A previous report in this journal 1 discussed pacinginduced reverse alternating Wenckebach periods (RAWP) in a pediatric cardiac population. The present communication, on the other hand, deals not only with this phenomenon in adult patients, but supplies

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Reverse-engineered models reveal differential membrane properties of autonomic and cutaneous unmyelinated fibers.

PLoS Computational Biology
Unmyelinated C-fibers constitute the vast majority of axons in peripheral nerves and play key roles in homeostasis and signaling pain. However, little is known about their ion channel expression, which controls their firing properties.
