Integrated metabolomic and transcriptomic analyses of flavonoid accumulation in different cultivars of Platostoma palustre.

Background: Platostoma palustre is a kind of plant resource with medicinal and food value, which has been differentiated into many different varieties after a long period of breeding. The cultivars of Taiwan(TW) and Pingyuan(PY) are widely grown in Guangdong, but a clear basis for species differentiation has not yet been established, resulting in the mixing of different species which limits their production and application.

Results: Regarding leaf surface morphology, the TW exhibited greater leaf area, non-glandular hairs, and the number of stomata than the PY.

Functional Analysis of in Controlling Root Regeneration from Detached Leaves.

root regeneration is the process by which adventitious roots form around the wound site from wounded or detached plant organs. The root regeneration process has been widely exploited in cutting technology used for vegetative propagation. Here, we employed detached leaf explants from to form adventitious roots for studying the process of root regeneration.

Hormone functions in adventitious root formation during cutting propagation of woody plants.

Cutting-induced adventitious root (AR) formation is crucial for vegetative propagation, a key method that produces plants identical to parent. However, many woody plants pose challenges for vegetative propagation due to difficulties in AR formation. Hormones play important roles during AR formation, with auxin serving as the key regulator and interacting with other hormones.

Study on the Migration Patterns of Oxygen Elements during the Refining Process of Ti-48Al Scrap under Electromagnetic Levitation.

This study investigated the migration patterns of oxygen in the deoxidation process of Ti-48Al alloy scrap using electromagnetic levitation (EML) technology. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) were employed to analyze the oxygen distribution patterns and migration path during EML. The refining process resulted in three types of oxygen migration: (1) escape from the lattice and evaporation in the form of AlO, AlO; (2) formation of metal oxides and remaining in the alloy melt; (3) attachment to the quartz tube wall in the form of metal oxides such as AlO and CrO.

Resting-State Functional Connectivity of the Cerebellum in Patients with Chronic Low Back Pain.

Objective: Chronic low back pain (cLBP) affects nociceptive responses in the cerebellum, which leads to increased pain perception and sensorimotor control dysfunction. This study aimed to investigate altered functional connectivity in the anterior and posterior lobes of the cerebellum during cLBP.

Design: Twenty patients with cLBP and 18 healthy participants underwent 3.

Anti-Type II Diabetic Effects of Coix Seed Prolamin Hydrolysates: Physiological and Transcriptomic Analyses.

Previous studies have demonstrated that enzymatically prepared coix seed prolamin hydrolysates (CHPs) contain several bioactive peptides that efficiently inhibit the activity of target enzymes (α-glucosidase and dipeptidyl kinase-IV) in type 2 diabetes mellitus (T2DM). However, the anti-T2DM effects and potential mechanisms of CHPs as a whole in vivo have not yet been systematically explored. Therefore, we evaluated the preventive, therapeutic, and modifying effects of CHPs on T2DM by combining physiological and liver transcriptomics with a T2DM mouse model.

Numerical Simulation of Electromagnetic-Thermal-Fluid Coupling for the Deformation Behavior of Titanium-Aluminum Alloy under Electromagnetic Levitation.

Electromagnetic levitation (EML) is a good method for high-temperature processing of reactive materials such as titanium-aluminum (Ti-Al) alloys. In this study, the oscillation and deformation processes of Ti-48Al-2Cr alloy specimens at different high-frequency currents during the EML process were simulated using the Finite Element Method and Arbitrary Lagrangian-Eulerian (ALE) methods. The data of oscillation, stabilization time, deformation, and distribution of electromagnetic-thermal-fluid fields were finally obtained.

Numerical Simulation of Segregation in Slabs under Different Secondary Cooling Electromagnetic Stirring Modes.

Secondary cooling electromagnetic stirring (S-EMS) significantly impacts the internal quality of continuous casting slabs. In order to investigate the effects of S-EMS modes on segregation in slabs, a three-dimensional numerical model of the full-scale flow field, solidification, and mass transfer was established. A comparative analysis was conducted between continuous electromagnetic stirring and alternate stirring modes regarding their impacts on steel flow, solidification, and carbon segregation.

Capecitabine or Capecitabine Plus Oxaliplatin Versus Fluorouracil Plus Cisplatin in Definitive Concurrent Chemoradiotherapy for Locally Advanced Esophageal Squamous Cell Carcinoma (CRTCOESC): A Multicenter, Randomized, Open-Label, Phase 3 Trial.

Purpose: This phase 3 trial aimed to compare the efficacy and safety of capecitabine or capecitabine plus oxaliplatin (XELOX) with those of fluorouracil plus cisplatin (PF) in definitive concurrent chemoradiotherapy (DCRT) for inoperable locally advanced esophageal squamous cell carcinoma (ESCC).

Methods: Patients were randomly assigned to receive two cycles of capecitabine, XELOX, or PF along with concurrent intensity-modulated radiation therapy. Patients in each arm were again randomly assigned to receive two cycles of consolidation chemotherapy or not.

Simulation and Experimental Study on the Effect of Superheat on Solidification Microstructure Evolution of Billet in Continuous Casting.

The control of the solidification structure of a casting billet is directly correlated with the quality of steel. Variations in superheat can influence the transition from columnar crystals to equiaxed crystals during the solidification process, subsequently impacting the final solidification structure of the billet. In this study, a model of microstructure evolution during billet solidification was established by combining simulation and experiment, and the dendrite growth microstructure evolution during billet solidification under different superheat was studied.

The F-box protein RhSAF destabilizes the gibberellic acid receptor RhGID1 to mediate ethylene-induced petal senescence in rose.

Roses are among the most popular ornamental plants cultivated worldwide for their great economic, symbolic, and cultural importance. Nevertheless, rapid petal senescence markedly reduces rose (Rosa hybrida) flower quality and value. Petal senescence is a developmental process tightly regulated by various phytohormones.
