The linear electro-optic effect offers a valuable means to control light properties via an external electric field. Lithium niobate (LN), with its high electro-optic coefficients and broad optical transparency ranges, stands out as a prominent material for efficient electro-optic modulators. The recent advent of lithium niobate-on-insulator (LNOI) wafers has sparked renewed interest in LN for compact photonic devices.

Objective: While some studies have explored the influencing factors of adolescent internet addiction, the risk factors and protective factors still require further discussion. This study aims to examine the mediating role of inhibitory control between anxiety and internet addiction among Chinese adolescents, as well as the moderating role of family support in the relationship between anxiety and inhibitory control.

Methods: A cross-sectional study was conducted through convenience sampling from February to March 2024 in seven schools across five provinces in China.

Article Synopsis
  • Electrically reconfigurable nonlinear metasurfaces allow for dynamic control of second-harmonic generation (SHG), leading to innovative uses in signal processing, light switching, and sensing.
  • Traditional methods have limitations due to weak SHG responses in metals and constraints in quantum well systems.
  • A new approach using lithium niobate (LN) combines the electro-optic effect with SHG, achieving an 11.3% modulation depth, which enhances the potential for tunable nonlinear light sources and advanced photonic applications.

Article Synopsis
  • Some studies have shown a link between bullying victimization and internet addiction in teens, but more research is needed on the factors that influence this relationship.
  • This study investigated how anxiety and inhibitory control mediate the connection between bullying and internet addiction among 1,673 Chinese adolescents.
  • Findings indicated that while bullying predicts internet addiction, this effect disappears when considering anxiety and inhibitory control, suggesting that support for bullying victims is crucial in preventing internet addiction.

  • * The study, conducted from July 2014 to May 2015, involved 52 participants and found that 30% of those receiving KB experienced adverse events, the most common being headaches and influenza, while fewer adverse events occurred in the placebo group.
  • * Results revealed that KB has a non-linear pharmacokinetic profile, with a plasma elimination half-life of 1.61-4.24 hours, and it showed favorable safety and tolerability across the tested dosage

Introduction: Human umbilical cord mesenchymal stem cells (UCMSCs) play an important role in repairing the damaged endometrium of intrauterine adhesion (IUA). Meanwhile, exosomes released by UCMSCs can mediate intercellular communication by delivering miRNAs. It has been shown that miR-543 level was reduced in IUA tissues.

Metasurfaces have emerged as a fascinating framework for nonlinear optics, which have advantages of a compact footprint and unprecedented flexibility in manipulating light. But their nonlinear responses are generally limited by the short interaction lengths with light. Therefore, further enhancement is highly desired for building high-efficiency nonlinear devices.

Kukoamine B, a small molecule compound, is being developed for the treatment of sepsis in a Phase II clinical trial. The objective of this study was to optimize dosing selection for a Phase IIb clinical trial using an exposure-response model. Data of 34 sepsis patients from a Phase IIa clinical trial were used in the model: 10 sepsis patients from the placebo group and a total of 24 sepsis patients from the 0.

Background: Cleft lip with or without cleft palate (CL/P) is the most common craniofacial anomaly with a high incidence of live births. The specific pathogenesis of CL/P is still unclear, although plenty of studies have been conducted. Variations of tumor protein 63 (TP63) was reported to be related to the phenotype of CL/P.

Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis (Mtb), leading to about a million deaths each year. EspR is a DNA binding protein of Mtb which regulates expression of multiple genes and the activity of ESX-1 secretion system of the bacteria, with itself being secreted out as a substrate of ESX-1. We explored the function of secreted EspR in host cells by overexpressing the protein in murine macrophage cell line RAW264.

Oxidative stress stimulates the Rho1 GTPase, which in turn induces the cell wall integrity (CWI) MAP kinase cascade. CWI activation promotes stress-responsive gene expression through activation of transcription factors (Rlm1, SBF) and nuclear release and subsequent destruction of the repressor cyclin C. This study reports that, in response to high hydrogen peroxide exposure, or in the presence of constitutively active Rho1, cyclin C still translocates to the cytoplasm and is degraded in cells lacking Bck1, the MAPKKK of the CWI pathway.

Bacille Calmette-Guérin (BCG), an attenuated strain of Mycobacterium bovis, is the only vaccine available for tuberculosis (TB) control. However, BCG is not an ideal vaccine and has two major limitations: BCG exhibits highly variable effectiveness against the development of TB both in pediatric and adult populations and can cause disseminated BCG disease in immunocompromised individuals. BCG comprises a number of substrains that are genetically distinct.
