It is generally accepted that jasmonate-ZIM domain(JAZ)repressors act to mediate jasmonate(JA)signaling via cORONATINE-INSenSITIVE1(cOI1)-mediated ***,we report a cryptic signaling cascade where a JAZ repressor,FvJAZ12,mediates multiple signaling inputs via phosphorylation-modulated subcellular translocation rather than the cOI1-mediated degradation mechanism in strawberry(Fragaria vesca).FvJAZ12 acts to regulate flavor metabolism and defense response,and was found to be the target of Fv MPK6,a mitogen-activated protein kinase that is capable of responding to multiple signal ***6 phosphorylates FvJAZ12 at the amino acid residues S179 and T183 adjacent to the PY residues,thereby attenuating its nuclear accumulation and relieving its repression for FvMYc2,which acts to control the expression of lipoxygenase 3(FvLOX3),an important gene involved in JA biosynthesis and a diverse array of cellular *** data reveal a previously unreported mechanism for JA signaling and decipher a signaling cascade that links multiple signaling inputs with fruit trait development.

The repair of large load-bearing bone defects requires superior mechanical strength, a feat that a single hydrogel scaffold cannot achieve. The objective is to seamlessly integrate optimal microarchitecture, mechanical robustness, vascularisation, and osteoinductive biological responses to effectively address these critical load-bearing bone defects. To confront this challenge, three-dimensional (3D) printing technology was employed to prepare a polycaprolactone (PcL)-based integrated scaffold. Within the voids of 3D printed PcL scaffold, a methacrylate gelatin (GelMA)/methacrylated silk fibroin (SFMA) composite hydrogel incorporated with parathyroid hormone (PTH) peptide-loaded mesoporous silica nanoparticles (PTH@MSNs) was embedded, evolving into a porous PTH@MSNs/GelMA/SFMA/PcL (PM@GS/PcL) scaffold. The feasibility of fabricating this functional scaffold with a customised hierarchical structure was confirmed through meticulous chemical and physical characterisation. compression testing unveiled an impressive modulus of 17.81 ± 0.83 MPa for the composite scaffold. Additionally, in vitro angiogenesis potential of PM@GS/ PcL scaffold was evaluated through Transwell and tube formation assays using human umbilical vein endothelium, revealing the superior cell migration and tube network formation. The alizarin red and alkaline phosphatase staining assays using bone marrow-derived mesenchymal stem cells clearly illustrated robust osteogenic differentiation properties within this scaffold. Furthermore, the bone repair potential of the scaffold was investigated on a rat femoral defect model using micro-computed tomography and histological examination, demonstrating enhanced osteogenic and angiogenic performance. This study presents a promising strategy for fabricating a microenvironment-matched composite scaffold for bone tissue engineering, providing a potential solution for effective bone defect repair. © 2024, chinese Medical Multimedia Press co Ltd.

We discuss the gravitational wave(GW)spectra predicted from the electroweak scalegenesis of the Higgs portal type with a large number of dark chiral flavors,which many flavor QcD would underlie and give the dynamical explanation of the negative Higgs portal coupling required to trigger the electroweak symmetry *** employ the linear-sigma model as the low-energy description of dark many flavor QcD and show that the model undergoes ultra-supercooling due to the produced strong first-order thermal phase transition along the(approximately realized)flat direction based on the Gildener-Weinberg *** through evaluation of the bubble nucleation/percolation,we address the reheating and relaxation processes,which are generically non-thermal and *** the reheating epoch in terms of the e-folding number,we propose proper formulae for the redshift effects on the GW frequencies and signal *** then turns out that the ultra-supercooling predicted from the Higgs-portal scalegenesis generically yields none of GW signals with the frequencies as low as nano Hz,unless the released latent heat is transported into another sector other than reheating the ***,models of this class prefer to give the higher frequency signals and still keeps the future prospected detection sensitivity,like at LISA,BBO,and DEcIGO,*** also find that with large flavors in the dark sector,the GW signals are made further smaller and the peak frequencies *** phenomenological consequences related to the multiple chiral scalars include the prediction of dark pions with the mass much less than TeV scale,which is also briefly addressed.

The electroreduction of carbon dioxide to generate multicarbon products is significant for achieving a carbon-neutral economy. However, the selectivity for multi-carbon products faces several challenges, such as the intricate nature of the multistep hydrogenation processes, slow reaction kinetics and the bicarbonate precipitate issue caused by alkaline conditions. These factors hinder the extensive utilization of this reaction. herein, we successfully developed and implemented a tandem electrolyzer cascade to separate and optimize the complex elementary reactions involved in the process of multi-carbon production. This approach enables us to enhance the Faradaic effic.ency (FE) of each step, consequently improving the overall performance of the system. An ethanol-assisted ionic-exchange method was utilized to synthesize a Ni
