Fundamentally, ferroelectrics must belong to a noncentrosymmetric space group, limiting the exploration of more new ferroelectric materials. We circumvent this limitation by triggering structure distortion and inducing ferroelectricity in centrosymmetric van der Waals group-IV monochalcogenide GeSe semiconductor that features unexpected intrinsic out-of-plane antiferroelectricity. Double-type and single-type hysteresis loops from electric measurements, bonding distortion observed in in-situ atomic imaging, and perpendicular polarization uncovered by first-principles calculations, confirm the intrinsic out-of-plane antiferroelectricity and the antiferroelectric-ferroelectric transition induced by the vertical external electric-field.

Background: Viral infections constitute a primary trigger for asthma exacerbations. While vaccines protect against viral infections by eliciting a Th1 immune response, the impact of the asthmatic immune milieu which is characterized by Th2 cytokine dominance and elevated IgE levels on post-vaccination antibody production remains elusive. Therefore, vaccination protocols tailored to asthma patients need to be formulated.

Enhancing photoluminescence (PL) efficiency in colloidal quantum dots is pivotal for next-generation near-infrared photodetectors, imaging systems, and photonic devices. Conventional methods, especially metal-based plasmonic structures, suffer from large optical losses, which limits their practical use. Here, we introduce a quasi-bound state in the continuum (quasi-BIC) metasurface on a silicon-on-insulator platform, tailored to provide high-quality factor resonances with minimized losses.

Salivary proteins play a crucial role in insects, facilitating nutrient acquisition and regulating complex interactions with host plants. However, most research has focused on pierce-sucking insects, leaving chewing insects, such as caterpillars largely unexplored. Carpenter moths (Cossidae) are important destructive wood bores whose larvae cause significant damage to forestry.

Electrochemical imaging enables an in-depth analysis of the interface heterogeneity and reaction kinetics of single entities. However, electrode passivation during electrochemical reactions decreases the active sites and harms the long-term stability. Here, we introduce a method using laser-induced photothermal effects to restore the electrochemical activity, which is particularly displayed as enhanced micrometric patterns in electrochemiluminescence (ECL) microscopy.

Mastering spatial frequency manipulation within momentum space is pivotal yet challenging, particularly in mitigating moiré patterns that significantly impair image quality across diverse applications. Conventional methods often require trade-offs in spatial resolution or fall short of completely eradicating unwanted frequencies, further burdened by complex post-processing demands. In this work, a novel coherent δ-function expansion technique implemented through an all-silicon metasurface, affording unparalleled synergistic control over arbitrarily selected spatial frequencies via refined k-space amplitude and phase modulations is introduced.

Local electrochemical impedance spectroscopy (LEIS) has emerged as a technique to characterize local electrochemical processes on heterogeneous surfaces. However, current LEIS heavily relies on lock-in amplifiers that have a poor gain effect for weak currents, limiting the achievements of high-spatial imaging. Herein, an integrated scanning electrochemical cell microscopy is developed by directly collecting the alternating current (AC) signal through a preamplifier.

  • The study aims to establish how anxiety and depression affect the progression and treatment outcomes of vitiligo, aiming to improve psychological care for patients.
  • Using a Mendelian randomization analysis and various statistical tests, researchers found that depression notably increases the risk of developing vitiligo and that different levels of anxiety and depression correlate with varying clinical characteristics in patients.
  • The results indicate that moderate to severe anxiety-depression negatively impacts treatment effectiveness, establishing a U-shaped relationship where the most significant influence occurs at specific anxiety-depression scores.

Cement kiln co-processing technique has been suggested as a promising disposal method for hexabromocyclododecane (HBCD)-containing construction wastes. However, concerns persist regarding the potential emissions of secondary brominated flame retardant (BFR) compounds. To address this, we conducted both field and laboratory experiments to elucidate the emission characteristics and formation mechanisms of BFRs during the co-processing of HBCD-containing waste in cement kilns.

Metabolic syndrome (MetS) is a group of metabolic abnormalities that identifies people at risk for diabetes and cardiovascular disease. MetS is characterized by lipid disorders, and non-alcoholic fatty liver disease (NAFLD) and diabetic kidney disease (DKD) are thought to be the common hepatic and renal manifestations of MetS following abnormal lipid metabolism. This paper reviews the molecular mechanisms of lipid deposition in NAFLD and DKD, highlighting the commonalities and differences in lipid metabolic pathways in NAFLD and DKD.

Human parainfluenza viruses (HPIVs) are a significant cause of acute lower respiratory tract infections (ALRTIs) among young children and elderly individuals worldwide. The four types of HPIVs (HPIV1-4) can cause recurrent infections and pose a significant economic burden on health care systems globally. However, owing to the limited availability of complete genome sequences, the genetic evolution of these viruses and the development of vaccines and antiviral treatments are hampered.

Endoplasmic reticulum (ER) stress is recognized as a crucial contributor to the progression of traumatic brain injury (TBI) and represents a potential target for therapeutic intervention. This study aimed to assess the potential of J147, a novel neurotrophic compound, in alleviating ER stress by modulating related signaling pathways, thereby promoting functional recovery in TBI. To this end, adult mice underwent controlled cortical impact (CCI) injury to induce TBI, followed by oral administration of J147 one-hour post-injury, with daily dosing for 3 to 7 days.

Exposure to the space microenvironment has been found to disrupt the homeostasis of intestinal epithelial cells and alter the composition of the microbiota. To investigate this in more detail and to examine the impact of ginsenoside Rb1, we utilized a mouse model of hindlimb unloading (HU) for four weeks to simulate the effects of microgravity. Our findings revealed that HU mice had ileum epithelial injury with a decrease in the number of intestinal stem cells (ISCs) and the level of cell proliferation.
