Stratification relieves constraints from steric hindrance in the generation of compact acto-myosin asters at the membrane cortex [PDF]

, 2020
Recent in-vivo studies have revealed that several membrane proteins are driven to form nanoclusters by active contractile flows arising from F-actin and myosin at the cortex. The mechanism of clustering was shown to be arising from the dynamic patterning

Sea-level trend variability in the Mediterranean during the 1993–2019 period

Frontiers in Marine Science, 2023
Sea-level change is one of the most concerning climate change and global warming consequences, especially impacting coastal societies and environments. The spatial and temporal variability of sea level is neither linear nor globally uniform, especially ...

Steric Effects in Electrolytes: A Modified Poisson-Boltzmann Equation

, 1998
The adsorption of large ions from solution to a charged surface is investigated theoretically. A generalized Poisson--Boltzmann equation, which takes into account the finite size of the ions is presented.

The electrophoretic membrane contactor: A mass-transfer-based methodology applied to the separation of whey proteins [PDF]

, 2011
In the electrophoretic membrane contactor (EMC), a porous membrane is used to establish a contact across two flowing liquids between which an electrically driven mass transfer takes places.

Six-Dimensional Quantum Dynamics of Adsorption and Desorption of H_2 at Pd(100): No Need for a Molecular Precursor Adsorption State

, 1996
We report six-dimensional quantum dynamical calculations of dissociative adsorption and associative desorption of the system H_2/Pd(100) using an ab-initio potential energy surface.

Steric Effects Govern the Photoactivation of Phytochromes

ChemPhysChem, 2016
AbstractPhytochromes constitute a superfamily of photoreceptor proteins existing in two forms that absorb red (Pr) and far‐red (Pfr) light. Although it is well‐known that the conversion of Pr into Pfr (the biologically active form) is triggered by a Z→E photoisomerization of the linear tetrapyrrole chromophore, direct evidence is scarce as to why this ...

Poisson-Nernst-Planck equations with steric effects - non-convexity and multiple stationary solutions

, 2017
We study the existence and stability of stationary solutions of Poisson-Nernst- Planck equations with steric effects (PNP-steric equations) with two counter-charged species.

Poisson-Fermi Formulation of Nonlocal Electrostatics in Electrolyte Solutions

Computational and Mathematical Biophysics, 2017
We present a nonlocal electrostatic formulation of nonuniform ions and water molecules with interstitial voids that uses a Fermi-like distribution to account for steric and correlation efects in electrolyte solutions.

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

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.
