To investigate the biological functions of () in . In this study, was cloned from , and an overexpression and subcellular localization expression vector for the gene was constructed. The gene was overexpressed in Arabidopsis and analyzed for phenotypic changes. The subcellular localization of was analyzed via -mediated transient expression in onion (.) epidermal cells. Phenotypic characterization of overexpressing Arabidopsis strains revealed that the branching angle of the transgenic strains was significantly greater than that of the wild type, and the anatomical structures of the stems and hypocotyls of the transgenic strains indicated that the vascular system of the transgenic strains developed more slowly than did that of the wild type. The subcellular localization of the gene revealed that the localization signals of the gene were mainly in the nucleus, and weak signals also appeared in the cell membrane, suggesting that the gene was mainly expressed mainly in the nucleus, with a small amount of expression in the cell membrane. This findings suggest that the gene influences the development of the branching angle of plants and xylem, and exerts its effects mainly in the nucleus and membrane. This study can help to characterize the regulatory effect of the gene on the branching angle and explore its effect on the branching angle and vascular system development, and also help to explore the possible molecular regulatory mechanism, which can provide a theoretical basis for further elucidation of the mechanism of action of the gene family.

Globally, at least 10 % of maternal deaths, caused by obstetric complications during pregnancy, are linked to preeclampsia or eclampsia. Preeclampsia-induced placental hypoxia leads to vascular injury and syncytial knot formation in terminal villi. Early delivery of preeclampsia placentas complicates comparisons with normotensive term placentas, while the placenta's non-planar structure limits the effectiveness of 2D histology for vascular analysis.

In the current study, gelatinized potato starch was modified by decanoyl chloride and curcumin via esterification and pH-driven method at two pH levels (pH 8 and 12), respectively, followed by precipitation and formation of anionic nanoparticles. The effects of modifications on the various properties of starch nanoparticles were investigated.

This groundbreaking study derives and tests several new dihedral torsion model potentials for constructing classical forcefields for atomistic simulations of materials. (1) The new angle-damped dihedral torsion (ADDT) model potential is preferred when neither contained equilibrium bond angle is linear (, ( and ) ≠ 180°), at least one of the contained equilibrium bond angles is ≥ 130° (, ( or ) ≥ 130°), and the dihedral torsion potential contains some odd-function contributions (, [] ≠ [-]). (2) The new angle-damped cosine only (ADCO) model potential is preferred when neither contained equilibrium bond angle is linear (, ( and ) ≠180°), at least one of the contained equilibrium bond angles is ≥ 130° (, ( or ) ≥ 130°), and the dihedral torsion potential contains no odd-function contributions (, [] = [-]).

This Perspective seeks to reconnect the current practice of nuclear magnetic resonance (NMR) spectroscopy in chemical structure and quantitative (qNMR) analysis with its roots in classical physics and quantum mechanics (QM). Rationales for this approach are derived from various angles, including focused reviews of the key parameters of the nuclear resonance phenomenon, the structural information richness of NMR spectra, and significant progress in both computational and spectrometer hardware. This provides collective reasoning for the reintegration of computational quantum mechanical spectral analysis (QMSA) into the contemporary practice of NMR spectral interpretation.
