Identification of Side Reactions in Cationic Polymerization of Viny Ethers with Polar Functional Groups in Their Substituents: Effect of Sort and Number of Functional Groups [PDF]

, 2008
To study effects of the sort and number of functional groups of vinyl ether monomers on the tendency of the side reaction in the HCl/ZnCl2-initiated controlled cationic polymerizations,2-(2-vinyloxyethoxy)ethyl phenylcarbamate(VEEPC)and 2-[2-(2 ...

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

FEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Methyl Methacrylate and Alpha-Methyl Styrene: New Strategy for Synthesis of Bloc Copolymers for Use in Potential Biomedical Applications Generated by an Ecologic Catalyst Called Maghnite (Algerian MMT)

Bulletin of Chemical Reaction Engineering & Catalysis, 2016
A new model for synthesis of the plastics, block copolymers were prepared from methyl methacrylate (MMA) and alpha-methyl styrene (α-MS) by cationic copolymerization in the presence of a new and efficient catalyst of “Maghnite-Na” at 0 °C in bulk.

Hydrophobic-cationic peptides modulate RNA polymerase ribozyme activity by accretion

Nature Communications, 2022
Macromolecular aggregates may have played an important role in the origin of life. Here, the authors report hydrophobic-cationic peptides that form insoluble aggregates, which reversibly accrete RNA on their surfaces, and enhance RNA polymerization by a ...

Copolymerization of ring-opening oxaspiro comonomer with denture base acrylic resin by free-radical/cationic hybrid polymerization

Journal of Pharmacy and Bioallied Sciences, 2021
Background: Polymerization shrinkage is an innate characteristic of thermo-polymerized denture base acrylic resin. Volumetric shrinkage is still a problem, although myriad material modifications.

Re‐Purposing Sapropterin (Kuvan) for ACTA2‐Related Multisystemic Smooth Muscle Dysfunction Syndrome: A Translational Mechanistic and First‐In‐Human Therapeutic Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Multisystemic smooth muscle dysfunction syndrome (MSMDS) is an ultra‐rare, ACTA2‐related disorder characterized by severe cerebrovascular disease, aortic aneurysms, and smooth muscle dysfunction. Using molecular dynamics simulations and in silico drug screening, we identified that sapropterin dihydrochloride (Kuvan) is a candidate capable of ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
