Fruit features are crucial for plant propagation, population growth, biodiversity preservation, and evolutionary survival. However, the synergistic regulatory mechanisms underlying the development of fruit traits such as color, shape and duration are unclear. Euscaphis japonica, whose fruits have a red-winged pericarp and persist for a long period of time, is an important ornamental plant in eastern Asia.

Respiratory syncytial virus (RSV) represents a significant threat, being a primary cause of critical lower respiratory tract infections and fatalities among infants and the elderly worldwide, and poses a challenge to global public health. This urgent public health challenge necessitates the swift development of safe and effective vaccines capable of eliciting robust immune responses at low doses. Addressing this need, our study investigated five self-amplifying mRNA (sa-mRNA) candidate vaccines that encode the various pre-fusion conformations of the RSV fusion protein.

Article Synopsis
  • Arsenic (As) and antimony (Sb) behavior in coastal ecosystems is influenced by various factors like nitrogen, sulfur, iron, and microbial communities, yet their specific interactions during river inflow are still largely unknown.
  • This study utilized a method combining diffusive gradients with high-throughput sequencing to examine how As and Sb are distributed and released in sediments from river and coastal tidal flat wetlands.
  • Key findings showed that As release varies with depth and is primarily influenced by factors like anaerobic ammonium oxidation and iron reduction, with different microbial communities present at river and coastal sites affecting these processes.

The migration and diffusion of Li, I and Ag impedes the realization of long-term operationally stable perovskite solar cells (PSCs). Herein, we report a multifunctional and universal molecular complexation strategy to simultaneously stabilize hole transport layer (HTL), perovskite layer and Ag electrode by the suppression of Li, I and Ag migration via directly incorporating bis(2,4,6-trichlorophenyl) oxalate (TCPO) into HTL. Meanwhile, TCPO co-doping results in enhanced hole mobility of HTL, advantageous energy band alignment and mitigated interfacial defects, thereby leading to facilitated hole extraction and minimized nonradiative recombination losses.

The development of noninvasive approaches to precisely control neural activity in mammals is highly desirable. Here, we used the ion channel transient receptor potential ankyrin-repeat 1 (TRPA1) as a proof of principle, demonstrating remote near-infrared (NIR) activation of endogenous neuronal channels in mice through an engineered nanoagonist. This achievement enables specific neurostimulation in nongenetically modified mice.

Background: Insomnia disorder with objective short sleep duration (ISS) phenotype is a more serious biological subtype than insomnia with objective normal sleep duration (INS) phenotype, and the neuroimaging data is helpful to understand the pathophysiology of the ISS phenotype. This study was to compare the amplitude of low-frequency fluctuation (ALFF), regional homogeneity (ReHo), and functional connectivity (FC) between the ISS phenotype and the INS phenotype.

Methods: In this cross-sectional study, 55 patients with insomnia disorder were recruited, and 22 of them were defined as the ISS phenotype by the objective cardiopulmonary coupling (CPC) technique.

Phosphorus, a crucial macronutrient essential for plant growth and development. Due to widespread phosphorus deficiency in soils, phosphorus deficiency stress has become one of the major abiotic stresses that plants encounter. Despite the evolution of adaptive mechanisms in plants to address phosphorus deficiency, the specific strategies employed by species such as Epimedium pubescens remain elusive.

Ion migration-induced intrinsic instability and large-area fabrication pose a tough challenge for the commercial deployment of perovskite photovoltaics. Herein, an interface heterojunction and metal electrode stabilization strategy is developed by suppressing ion migration via managing lead-based imperfections. After screening a series of cations and nonhalide anions, the ideal organic salt molecule dimethylammonium trifluoroacetate (DMATFA) consisting of dimethylammonium (DMA) cation and trifluoroacetate (TFA) anion is selected to manipulate the surface of perovskite films.

Objective: Unilateral temporomandibular joint ankylosis with jaw deformity (UTMJAJD) may require simultaneous total joint prosthesis (TJP) reconstruction, sagittal split ramus (SSRO), and Le Fort I osteotomies. The purpose of this study was to evaluate outcomes in patients treated with these procedures.

Methods: Patients diagnosed UTMJAJD between 2016 and 2018 were selected for the study.

The instability of top interface induced by interfacial defects and residual tensile strain hinders the realization of long-term stable n-i-p regular perovskite solar cells (PSCs). Herein, one molecular locking strategy is reported to stabilize top interface by adopting polydentate ligand green biomaterial 2-deoxy-2,2-difluoro-d-erythro-pentafuranous-1-ulose-3,5-dibenzoate (DDPUD) to manipulate the surface and grain boundaries of perovskite films. Both experimental and theoretical evidence collectively uncover that the uncoordinated Pb ions, halide vacancy, and/or I─Pb antisite defects can be effectively healed and locked by firm chemical anchoring on the surface of perovskite films.

Facing the defects and energy barrier at the interface of perovskite solar cells, we propose a chiral molecule engineering strategy to simultaneously heal interfacial defects and regulate interfacial energy band alignment. S-ibuprofen (S-IBU), R-ibuprofen (R-IBU), and racemic ibuprofen (rac-IBU) are used to post-treat perovskite films. rac-IBU molecules possess the strongest anchoring on the surface of perovskites among all chiral molecules, translating into the best defect passivation effect.

  • Hort. is adversely affected by cadmium (Cd) contamination, impacting its growth and quality, but the specific mechanisms behind this impact are not well understood.
  • A study was conducted using physiological and transcriptomic analyses on plants exposed to various Cd concentrations, revealing that Cd stress hinders biomass and root growth while activating antioxidant defenses.
  • The results indicate that root tissues accumulate Cd and show downregulation of photosynthesis-related genes, while certain transport proteins and pathways related to cell wall modification and hormone signaling are positively affected, suggesting potential strategies for Cd tolerance in Hort.
