The interplay between fullerene cages and endohedral units is crucial for the stability and properties of endohedral metallofullerenes (EMFs). However, clear visualization of such an interplay remains rare due to the scarcity of suitable comparative EMFs molecules. Here, we report for the first time a unique cage elongation along the cycloparaphenylene belt, induced by a direct C insertion within a (6)-C cage.

This study aimed to investigate the effects of dual tasks on gait performance and examine the test-retest reliability of gait assessments in older adults. Gait data from eighteen healthy older adults were collected using the Vicon 3D motion capture system.

Methods: In this study, we identified the AMGT1P33 promoter in the genome of the mangrove tree species Avicennia marina using PromPredict and then verified its promoter function according to the transient expression of GUS.
Background: The Merulinidae family belonging to the order Scleractinia is mainly distributed in the Indo-Pacific and Caribbean regions and often constitute the most dominant species of coral reefs. Mitochondrial genome is a key tool for studying the phylogeny and adaptation. Only a few studies have conducted the characteristics analyses of mitochondrial genome in the Merulinidae family.

Perceptual learning (PL) and transcranial electrical stimulation (tES) have emerged as promising interventions for vision rehabilitation, showing potential in restoring residual visual functions. The Glaucoma Rehabilitation using ElectricAI Transcranial stimulation (GREAT) project aims to investigate whether combining PL and tES is more effective than using either method alone in maximizing the visual function of glaucoma patients.

The research on electron transfer coupled spin transition regulating the valence state and spin state transition of metal ions is promising and challenging. Herein, we report a cyano-bridged {FeIII2FeII2} molecular square complex, {[Fe(Tp)(CN)] [Fe(bnbpen)]}(ClO)·8CHOH (1·8CHOH, bnbpen = ,'-bis-(2-naphthylmethyl)-,'-bis(2-picolayl)-ethylenediamine), and its free of solvents form (1). Combined single-crystal X-ray diffraction, temperature-dependent infrared (IR) spectra, magnetic measurements, and Mössbauer spectra reveal that 1·8CHOH and 1 exhibit reversible one-step and two-step electron transfer coupled spin transition (ETCST) with temperature change, between the low-temperature state {Fe(μ-CN)Fe} (LS = low spin, HS = high spin) and the high-temperature state {Fe(μ-CN)Fe}, respectively.

Starch accounts for up to 90% of the dry weight of rice endosperm and is a key determinant of grain quality. Although starch biosynthesis enzymes have been comprehensively studied, transcriptional regulation of starch-synthesis enzyme-coding genes (SECGs) is largely unknown. In this study, we explored the role of a NAC transcription factor, OsNAC24, in regulating starch biosynthesis in rice.

Rice is a major food crop that sustains approximately half of the world population. Recent worldwide improvements in the standard of living have increased the demand for high-quality rice. Accurate identification of quantitative trait loci (QTLs) for rice grain quality traits will facilitate rice quality breeding and improvement.

The study of the effects of paleoclimatic and geological changes on genetic diversity, genetic structure, and species differentiation of desert plants is not only helpful in understanding the strategies of adaptation of plants to arid habitats, but can also provide reference for the protection and restoration of vegetation in desert ecosystem. Northwest China is an important part of arid regions in the northern hemisphere.

Sugar allocation between vegetative and reproductive tissues is vital to plant development, and sugar transporters play fundamental roles in this process. Although several transcription factors have been identified that control their transcription levels, the way in which the expression of sugar transporter genes is controlled at the posttranscriptional level is unknown. In this study, we showed that OsRRM, an RNA-binding protein, modulates sugar allocation in tissues on the source-to-sink route.
