Norbornene Homopolymerization Limits Cell Spreading in Thiol–Ene Photoclick Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
Thiol–norbornene click reactions are often used in the development of cell‐permissive 3D hydrogels. However, ene–ene crosslinks in other thiol–ene systems are known to limit permissivity. This study demonstrates the negative effects of norbornene homopolymerization on 3D cell spreading and circumvents the issue by modulating polymer degree of ...

A procedure for the determination of proteolytic activity [PDF]

open access: yes, 1950
The difficulties introduced by the desire to maintain a constant pH during an enzyme-catalyzed hydrolysis of peptide-like substrates and at the same time to determine the extent of hydrolysis by an acid-base titration have been pointed out (1), but to ...

Synthetic Hydrogels Incorporating Hydrolytic/Nonhydrolytic Macromer Ratios Exhibit Improved Tunability of In Vivo Degradation and Immune Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
A synthetic 4‐arm maleimide‐terminated poly(ethylene glycol) (PEG‐4MAL) hydrogel system that combines hydrolytic ester‐linked macromer (PEG‐4eMAL) with nondegradable amide‐linked macromer (PEG‐4aMAL) in various stoichiometric ratios to tune the degradability rate. The macromers are crosslinked with dithiothreitol via thiol‐maleimide click reaction. The

Intracellular proteolytic enzymes of liver [PDF]

open access: yesExperimental Biology and Medicine, 1910
The influence of reaction upon autolysis of animal tissues has been exhaustively studied. All observers agree upon the favorable influence of a weak acid medium, and upon the inhibitory effect alkaline reaction. As an example of the influence of reaction upon autolysis, 2.5 grams of liver after five days at 37 degrees yield the following equivalents of

Integrin β4‐Enriched Small Extracellular Vesicle as Drug Delivery Vehicle for Targeting Pulmonary Metastasis of Hepatocellular Carcinoma

open access: yesAdvanced Healthcare Materials, EarlyView.
The expression of integrin β4 (ITGβ4) on small extracellular vesicle (sEV) correlates with lung‐tropism. Enrichment of ITGβ4 on sEVs enhances their lung‐targeting ability. The sEVs loaded with doxorubicin exhibit superior therapeutic efficacy in a lung metastasis mouse model.

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

open access: yesAdvanced Healthcare Materials, EarlyView.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng
