The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

FEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Effects of Unsteady Heat Transfer on Behaviour of Commercial Hydro-Pneumatic Accumulators [PDF]

arXiv, 2020
Hydraulic accumulators play a central role as energy storage in nearly all fluid power systems. The accumulators serve as pulsation dampers or energy storage devices in hydro-pneumatic suspensions. The energy carrying gas is compressed and decompressed, often periodically.

Mapping the Energy Cascade in the North Atlantic Ocean: The Coarse-graining Approach [PDF]

, 2017
A coarse-graining framework is implemented to analyze nonlinear processes, measure energy transfer rates and map out the energy pathways from simulated global ocean data. Traditional tools to measure the energy cascade from turbulence theory, such as spectral flux or spectral transfer rely on the assumption of statistical homogeneity, or at least a ...

Distance Dependence of the Energy Transfer Rate From a Single Semiconductor Nanostructure to Graphene

, 2015
The near-field Coulomb interaction between a nano-emitter and a graphene monolayer results in strong F\"orster-type resonant energy transfer and subsequent fluorescence quenching.

Social context prevents heat hormetic effects against mutagens during fish development

FEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Plasmon-Coupled Resonance Energy Transfer.

Journal of Physical Chemistry Letters, 2017
In this study, we overview resonance energy transfer between molecules in the presence of plasmonic structures and derive an explicit Förster-type expression for the rate of plasmon-coupled resonance energy transfer (PC-RET).

Energy transfer in monomeric phycoerythrocyanin

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2004
Phycoerythrocyanin (PEC) is part of the phycobilisome of cyanobacteria. Its monomer carries one phycoviolobilin and two phycocyanobilins (PCB) as chromophores. For an understanding of the complicated energy transfer in phycobilisomes, a detailed knowledge of the processes in the constituting building proteins is indispensable.

Spot‐14 and its paralog Spot‐14R regulate expression of metabolic and thermogenic pathway genes in murine brown and beige adipocytes

FEBS Letters, EarlyView.
Spot‐14 and Spot‐14R play distinct roles in regulating metabolism in brown and beige adipocytes. While both influence lipid and glucose pathways, Spot‐14 uniquely controls thermogenic gene expression. This dual regulation balances energy storage and heat production, highlighting potential therapeutic targets for obesity and metabolic disorders. Spot 14
