Dependence of the energies of fusion on the intermembrane separation: optimal and constrained

open access: yes, 2007
We calculate the characteristic energies of fusion between planar bilayers as afunction of the distance between them, measured from the hydrophobic/hydrophilic interface of one of the two nearest, cis, leaves to the other.

PH regulation of amphotericin B channels activity in the bilayer lipid membrane [PDF]

open access: yes, 2016
Background: Amphotericin B (AmB) is a polyene antibiotic frequently applied in the treatment of systemic fungal infections in spite of its secondary effects.

In situ radiographic and ex situ tomographic analysis of pore interactions during multilayer builds in laser powder bed fusion

open access: yesAdditive Manufacturing, 2020
Porosity and high surface roughness can be detrimental to the mechanical performance of laser powder bed fusion (LPBF) additive manufactured components, potentially resulting in reduced component life.

Tension-induced vesicle fusion: pathways and pore dynamics [PDF]

open access: yesSoft Matter, 2008
The dynamics of tension-induced fusion of two vesicles is studied using dissipative particle dynamics (DPD) simulations. The vesicle membranes use an improved DPD parameter set that results in their sustaining only a 10-30% relative area stretch before rupturing on the microsecond timescale of the simulations.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Hardness, grainsize and porosity formation prediction on the Laser Metal Deposition of AISI 304 stainless steel [PDF]

open access: yes, 2018
The presented numerical model solves the heat and mass transfer equations in the Laser Metal Deposition process and based on the evolution of the thermal field predicts the grainsize, the resulting hardness and evaluates the pores formation probability ...

Nanodisc-cell fusion: control of fusion pore nucleation and lifetimes by SNARE protein transmembrane domains

open access: yesScientific Reports, 2016
The initial, nanometer-sized connection between the plasma membrane and a hormone- or neurotransmitter-filled vesicle –the fusion pore– can flicker open and closed repeatedly before dilating or resealing irreversibly.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Synaptobrevin2 monomers and dimers differentially engage to regulate the functional trans-SNARE assembly

open access: yesLife Science Alliance
This work demonstrates different factors controlling the synaptobrevin2 dimer-to-monomer ratio, which has ramifications in fusion pore stability. The precise cell-to-cell communication relies on SNARE-catalyzed membrane fusion.

Membranes of semicrystalline aliphatic polyamide nylon 4,6: Formation by diffusion-induced phase separation [PDF]

open access: yes, 1993
The preparation of membranes of nylon 4,6 by diffusion-induced phase separation (DIPS) using formic acid as a solvent and water as a nonsolvent was studied.
