Predictive model of polymer reaction kinetics and coagulation behavior in seeded emulsion co- and ter-polymerizations [PDF]
arXiv, 2020 A mathematical model to describe the emulsion polymerization kinetics of co- and ter-polymerizations is developed. The model is based on the classical Smith-Ewart (SE) equations, within the pseudo-homopolymerization approach, with state-of-the-art models for radical entry and desorption.

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

A recoverable versatile photo-polymerization initiator catalyst [PDF]
arXiv, 2012 A photo-polymerization initiator based on an imidazolium and an oxometalate, viz., (BMIm)2(DMIm) PW12O40 (where, BMIm = 1-butyl-3-methylimizodium, DMIm = 3,3'-Dimethyl-1,1'-Diimidazolium) is reported. It polymerizes several industrially important monomers and is recoverable hence can be reused.

Molecular Oncology, EarlyView.This study investigates an alternative approach to reactivating the oncosuppressor p53 in cancer. A short peptide targeting the association of the two p53 inhibitors, MDM2 and MDM4, induces an otherwise therapeutically active p53 with unique features that promote cell death and potentially reduce toxicity towards proliferating nontumor cells.

Uni-directional polymerization leading to homochirality in the RNA world
, 2005 The differences between uni-directional and bi-directional polymerization are considered. The uni-directional case is discussed in the framework of the RNA world. Similar to earlier models of this type, where polymerization was assumed to proceed in a bi-
