Technique for the polymerization of monomers for PPQ/graphite fiber composites [PDF]
, 1973 Impregnation of fiber prior to appreciable polymerization completely eliminates impregnation problems encountered with use of high viscosity high molecular weight polyphenylquinoxalines (PPQ) solutions. Major part of polymerization of reactant mixture is

Molecular Oncology, EarlyView.We quantified and cultured circulating tumor cells (CTCs) of 62 patients with various cancer types and generated CTC‐derived tumoroid models from two salivary gland cancer patients. Cellular liquid biopsy‐derived information enabled molecular genetic assessment of systemic disease heterogeneity and functional testing for therapy selection in both ...

Superselective adsorption of multivalent polymeric particles [PDF]
arXiv, 2020 Multivalency is a common biological mechanism of formation of strong reversible and selective bonds by grouping weak bonds. Polymers often act as a scaffold to which multiple binding groups are attached. Here I present an analytical theory allowing to calculate avidity and selectivity for multivalent polymeric particles using tools from the theory of ...

Thermodynamic Analysis of a Polymerization-Induced Phase Separation in Nanoparticle-Monomer-Polymer Blends [PDF]
Macromolecules, 40 (22), 8082-8086 (2007), 2013 We perform a thermodynamic analysis of the polymerization-induced phase separation in nanoparticle-monomer-polymer blends using a simple model recently proposed by V. V. Ginzburg (Macromolecules 2005, 38, 2362.). The model was adapted for ternary blends constituted by nanoparticles, a monomer and a linear polymer, where the relative fractions of ...

Synthesis of neutral nickel catalysts for ethylene polymerization – the influence of ligand size on catalyst stability [PDF]
, 2003 A facile synthesis of nickel salicylaldimine complexes with labile dissociating ligands is described. In addition to producing highly active ethylene polymerization catalysts, important insights into the effect of ligand size on catalyst stability and ...

THE POLYMERIZATION OF PROTEINS [PDF]
Journal of General Physiology, 1950 It was found that actin solutions contain ATP. Experiments in which hexokinase and creatine were added to actin show that the ensuing dephosphorylation of ATP affects actin so that it will not polymerize.

Molecular Oncology, EarlyView.CircCCNB1 expression is down‐regulated in nasopharyngeal carcinoma (NPC); thus, less NF90 protein is bound to circCCNB1 and more binds to pri‐miRNAs, blocking their (pri‐miRNAs) binding to DGCR8 and inhibiting the processing and generation of miR‐15b‐5p/miR‐7‐1‐3p. Furthermore, decreased miR‐15b‐5p/miR‐7‐1‐3p promotes the expression of the target genes
