Design of epidermal growth factor immobilization on 3D biocompatible scaffolds to promote tissue repair and regeneration

open access: yesScientific Reports, 2021
Exogenous application of human epidermal growth factor (hEGF) stimulates epidermal wound healing. The aim of this study was to develop bioconjugates based on hEGF mimicking the protein in its native state and thus suitable for tissue engineering ...

Ab-initio study of the effect of bromide mixing into RbPbI$_3$ on the structural, electronic and optical properties [PDF]

open access: yesarXiv, 2022
The ultra-high efficiency and cost-effective photovoltaics based on halide preovskites have brought a revolution to ongoing photovoltaic research, surpassing the expectations of the scientific community. However, structural stability is a severe issue that hinders their wide-scale integration at the device level.

Tropomyosin-like properties of clathrin light chains allow a rapid, high-yield purification. [PDF]

open access: yes, 1983
The light chains (LCa and LCb) of bovine brain clathrin are resistant to heat denaturation by boiling, a property shared by tropomyosin (Bailey, K., 1948, Biochem. J., 43:271-281).

Photoaffinity labeling coupled to MS to identify peptide biological partners: Secondary reactions, for better or for worse?

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Affinity photolabeling is a smart method to study noncovalent and transient interactions and provide a submolecular picture of the contacts between interacting partners. In this review, we will focus on the identification of peptide partners using photoaffinity labeling coupled to mass spectrometry in different contexts such as in vitro with a

Electrophilic C(sp2)−H Cyanation with Inorganic Cyanate (OCN−) by PIII/PV=O‐Catalyzed Phase Transfer Activation

open access: yesAngewandte Chemie, Volume 136, Issue 39, September 23, 2024.
An organophosphorus‐catalyzed method for the direct electrophilic cyanation of C(sp2)−H nucleophiles using inorganic sodium cyanate (NaOCN) is reported. These results demonstrate the feasibility of deoxyfunctionalization of insoluble inorganic salts by PIII/PV=O catalyzed phase transfer activation. Abstract An organophosphorus ‐catalyzed method for the
