Structure and function of the bacterial heterodimeric ABC transporter CydDC: stimulation of ATPase activity by thiol and heme compounds. [PDF]

, 2014
In Escherichia coli, the biogenesis of both cytochrome bd-type quinol oxidases and periplasmic cytochromes requires the ATP-binding cassette-type cysteine/GSH transporter, CydDC.

Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

Advanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation

Advanced Healthcare Materials, EarlyView.
This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).

Role of glutathionylation in infection and inflammation [PDF]

, 2019
Glutathionylation, that is, the formation of mixed disulfides between protein cysteines and glutathione (GSH) cysteines, is a reversible post-translational modification catalyzed by dierent cellular oxidoreductases, by which the redox state of the cell

Development of a Synthetic Hydrogel to Foster Microvascularization of an Endometriosis Microphysiological System

Advanced Healthcare Materials, EarlyView.
ABSTRACT The ascent of novel alternative methods in drug development spotlights the dual needs for improved biological fidelity to in vivo, along with reproducibility, especially in regulatory applications. The need for pre‐clinical models of patient‐derived endometriosis lesions motivates the development of a vascularizable, completely synthetic ...

Contact angle measurements on superhydrophobic Carbon Nanotube Forests : effect of fluid pressure

, 2005
In this paper the effect of pressure on the contact angle of a water drop on superhydrophobic Carbon Nanotube (CNT) forests is studied. Superhydrophobic CNT forests are obtained from a new and simple functionalization strategy, based on the gold-thiol ...

Bifunctional Surfaces With Immobilized Antibodies and Bioactive Peptides Mediate Selective Capture and Proliferation of Endothelial Colony‐Forming Cells

Advanced Healthcare Materials, EarlyView.
A tunable bifunctional surface is developed by combining Fc‐binding peptides and RGD motifs to present oriented antibodies alongside integrin‐mediated signaling. The platform selectively captures endothelial colony‐forming cells while promoting their adhesion and proliferation.

Diisopropylamine as a single catalyst in the synthesis of aryl disulfides

Green Processing and Synthesis, 2018
The search for less time-consuming and inexpensive methods for the synthesis of disulfides continues to be a hot subject of research. Herein, we report that diisopropylamine (iPr2NH) can act as a very effective catalyst for this process.
