Published: May 2007

Real-time PCR assays for Plasmodium species utilizing universal and species-specific primers were compared to investigate variables influencing decreased assay sensitivity. Sequence variation in oligomer targets and competitive inhibition of dual-species templates in universal-primer mixes were found to decrease assay sensitivity.

Unlocking hexafluoroisopropanol as a practical anion-binding catalyst for living cationic polymerization.

Angew Chem Int Ed Engl

January 2025

Chang Chun Institute of Applied Chemistry Chinese Academy of Sciences, Key Laboratory of Polymer Ecomaterials, 5625 Renmin Street, Changchun, , 130022, Changchun, CHINA.

Living cationic polymerization (LCP) is a classical technique for precision polymer synthesis; however, due to the high sensitivity of cationic active species towards chain-transfer/termination events, it is notoriously difficult to control polymerization under mild conditions, which inhibits its progress in advanced materials engineering. Here, we unlock a practical anion-binding catalytic strategy to address the historical dilemma in LCP. Our experimental and mechanistic studies demonstrate that commercially accessible hexafluoroisopropanol (HFIP), when used in high loading, can create higher-order HFIP aggregates to tame dormant-active species equilibrium via non-covalent anion-binding principle, in turn inducing distinctive polymerization kinetics behaviors that grant efficient chain propagation while minimizing competitive side reactions.

To ensure their survival, animals must be able to respond adaptively to threats within their environment. However, the precise neural circuit mechanisms that underlie flexible defensive behaviors remain poorly understood. Using neuronal manipulations, machine learning-based behavioral detection, electron microscopy (EM) connectomics and calcium imaging in Drosophila larvae, we map second-order interneurons that are differentially involved in the competition between defensive actions in response to competing aversive cues.

This study aimed to investigate the inhibitory pathways of basic amino acids (Histidine, Lysine, and Arginine) on the formation of PhIP in the glucose/creatinine/phenylalanine model system. The inhibitory effects were found to depend on both the chemical structure and concentration of the basic amino acids, with Lysine showing the strongest inhibitory effect. Due to the lower reaction barrier of basic amino acids, their potential inhibitory mechanism is proposed to involve competition with phenylalanine for glucose.

We explored the influence of the TCL6/miR-876-5p axis on breast cancer cell proliferation and migration. Using The Cancer Genome Atlas (TCGA) database, we evaluated the expression of TCL6 in breast cancer patients and studied its effects on cell proliferation, migration, and the cell cycle in vitro. The regulatory effect of miR-876-5p on myosin light chain-2 (MYL2) 3' untranslated regions (3'UTR) was analyzed through luciferase reporter assays, and rescue experiments confirmed TCL6-driven upregulation of MYL2 via a competitive RNA binding mechanism.

Electrocatalytic dehalogenative deuteration is a sustainable method for precise deuteration, whereas its Faradaic efficiency (FE) is limited by a high overpotential and severe D evolution reaction (DER). Here, Cu site-adjusted adsorption and crown ether-reconfigured interfacial DO are reported to cooperatively increase the FE of dehalogenative deuteration up to 84% at -100 mA cm. Cu sites strengthen the adsorption of aryl iodides, promoting interfacial mass transfer and thus accelerating the kinetics toward dehalogenative deuteration.
