Unravelling the monomer molar ratio modulation of the optoelectronics of Poly(propylene imine) tetra(thiophen-2-ylmethylene-amine)-co-poly(3-hexylthiophene-2,5-diyl) copolymer

Journal of Science: Advanced Materials and Devices
Tuning the molecular structure of a copolymer is of considerable importance for optimizing its optoelectronic and morphological properties. This will enormously help in improving and understanding the performance of a copolymer as a donor material in ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

A Programmed DNA Dynamic Assembly‐Guided Molecular Amplifier for Authentic Information Decryption

Advanced Science
Nucleic acid‐based cryptographic approaches are an innovative emerging field for information process. However, the poor reproducibility and interference from bioenvironment of the existing decryption led to different binary translation according to the ...

Behenic Acid Monolayer and Bilayer Assemblies- A Study of Concanavalin A (Con A) Adsorption and its Interaction with Dextran Using Surface Plasmon Resonance Spectroscopy and Microscopy [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1993
Deposition of behenic acid (B.A) mono and bilayers onto gold coated surfaces was performed by Langmuir-Blodget dip-casting technique. Surface Plasmon resonance (SPR) and ellipsometry methods were employed for investigation of the monolayer and bilayer ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Non-Invasive Assessment of Skin Barrier Properties: Investigating Emerging Tools for In Vitro and In Vivo Applications

Cosmetics, 2017
There is increasing interest in the development of non-invasive tools for studying the properties of skin, due to the potential for non-destructive sampling, reduced ethical concerns and the potential comparability of results in vivo and in vitro.

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 ...

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 ...
