An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes
FEBS Letters, EarlyView.GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Operating mechanism and optimization of dynamic absorber for a parametric excitation system
Nihon Kikai Gakkai ronbunshu, 2015 The effectiveness of a dynamic absorber for self-excited vibration, such as parametric resonance, has been known for several years. However, in the case of self-excited vibration, the operating mechanism of a dynamic absorber is still poorly understood ...

Switchable Wideband Terahertz Absorber Based on Refractory and Vanadium Dioxide Metamaterials
IEEE Photonics Journal, 2023 Achieving actively tunable metamaterial absorption is a significant development direction. Phase-transition materials have attracted growing interest for the use in nanophotonics owing to their flexibility. In this work, we firstly demonstrate a wideband

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Noise reduction due to structural modification in the coupled structural-acoustic system
Nihon Kikai Gakkai ronbunshu, 2015 With the development of box structure like a car or train, noise reduction is required for such structures with cabin inside. Noise problem with structural vibration has been studied as coupled structural-acoustic system.

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Vibration reduction of traffic signal pole by dynamic absorber that generates electrical power
Nihon Kikai Gakkai ronbunshu, 2015 The authors propose an absorber that generates electrical power in order to not only suppress vibration but also get electrical energy when many traffic signal poles are oscillated by wind, traffic turbulence.

Dynamically modulated perfect absorbers
Physical Review A, 2019 We introduce the concept of multichannel dynamically modulated perfect absorbers (DMPAs), which are periodically modulated lossy interferometric traps that completely absorb incident monochromatic waves. The proposed DMPA protocols utilize a Floquet engineering approach which produces a variety of emerging phenomena and features: reconfigurability of ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
