Synthesis and Properties of Novel Alkyl-Substituted Hexaazacyclophanes and Their Diradical Dications.

Radicals based on arylamine cyclophanes can be used as functional materials and show application potential in fields such as synthetic chemistry, molecular electronic components, organic light-emitting diodes, and catalytic chemistry. Using a Buchwald-Hartwig palladium-catalyzed aryl halide amination method, we synthesized a series of neutral hexaazacyclophane compounds - with different substituents in the positions of the phenyl rings. Three characteristic high-spin hexaazacyclophane diradical dications were obtained by two-electron oxidation using AgSbF: •2[SbF], •2[SbF], and •2[SbF].

Evaluation of Antioxidant Activity and Drug Delivery Potential of Cell-Derived Extracellular Vesicles from Blanco cv. 'Dahongpao'.

Plant extracellular vesicles (PEVs) have attracted increasing attention due to their rich composition, good antioxidant and anti-inflammatory activity, and ability to transport drugs. As a common fruit, citrus is an ideal material for extracting PEVs because of the diversity and abundance of bioactive substances in it. In our study, citrus-derived extracellular vesicles (CEVs) were extracted from red mandarin ( Blanco cv.

The OsSGS3-tasiRNA-OsARF3 module orchestrates abiotic-biotic stress response trade-off in rice.

Recurrent heat stress and pathogen invasion seriously threaten crop production, and abiotic stress often antagonizes biotic stress response against pathogens. However, the molecular mechanisms of trade-offs between thermotolerance and defense remain obscure. Here, we identify a rice thermo-sensitive mutant that displays a defect in floret development under high temperature with a mutation in SUPPRESSOR OF GENE SILENCING 3a (OsSGS3a).

Comparative Analysis of the Impact of Three Drying Methods on the Properties of Blanco cv. Dahongpao Powder and Solid Drinks.

Blanco cv. Dahongpao is a traditional Chinese citrus variety. Due to the high investment in storage and transport of Blanco cv.

= 1/2 tetracene monoradical cation/anion: ion-based one-dimensional antiferromagnetic chains.

The monoradical cation 1˙+ and anion 1˙- based on tetracene were generated by one-electron oxidation and one-electron reduction of the bulky tetracene (1), respectively, which contain the largest π-fused skeletons reported to date. For monoradical species, 1˙+ and 1˙-, EPR spectra and DFT calculation results indicate the spin density delocalized over the whole molecules. Notably, in the solid state, 1˙+ and 1˙-, respectively, pack into (1˙+) and (1˙--K-crown), characterized by single-crystal X-ray diffraction studies.

A novel method for noninvasive diagnosis of monogenic diseases from circulating fetal cells.

Objective: To establish a method for noninvasive fetal cell isolation from maternal blood and prenatal testing of monogenic diseases by a combination of direct sequencing and targeted NGS-based SNP haplotyping from single fetal cells.

Method: Peripheral blood of pregnant women in two families (congenital deafness and ichthyosis) was collected. After density-based separation and immunostaining with multiple biomarkers, candidate fetal cells were identified by high-throughput imagine analysis and picked up by automation.
