Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

open access: yesAdvanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Diagnosis of yolk peritonitis

open access: yesRUDN Journal of Agronomy and Animal Industries, 2014
We have studied the performance pre-slaughter and post-mortem diagnosis of yolk peritonitis from laying hens of different breeds and age groups. Also identified the characteristic clinical signs and pathological changes in the organs and tissues of chickens at different stages of development of the yolk peritonitis. Revealed pathognomonic signs of yolk

Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...
