Research progress of bioactive glass in the remineralization of dental hard tissue.

Bioactive glass (BAG) is a widely researched biomaterial in medical science. Renowned for its exceptional biocompatibility and excellent biosafety profile, it has been extensively utilized in clinical practice, especially in the repair and regeneration of bone and soft tissue. In recent years, biomaterials researchers have intensified their exploration of BAG within dental medicine, spanning prosthodontics, oral and maxillofacial surgery, and periodontology.

TA@PN System-Mediated Collagen Cross-Linking and Biomimetic Mineralization for Dentinal Tubule Occlusion in Dentin Hypersensitivity Management.

The hydrodynamic theory suggests that the multidirectional flow of fluids within demineralized dentinal tubules (DTs) in response to external stimuli excites pulpal nerve fibers to produce nociception, causing dentin hypersensitivity (DH). Meanwhile, demineralized dentin's collagen fibers are susceptible to attack by endogenous enzymes and disintegration, continuously decreasing the resistance of the dentin surface and dentin's mechanical properties. Recross-linking and mineralizing damaged collagen fibers, closing DTs, and integrating antienzymatic functions remain significant challenges in dental regenerative medicine.

In situ Raman reveals the critical role of Pd in electrocatalytic CO2 reduction to CH4 on Cu-based catalysts.

Electrocatalytic CO2 reduction reaction (CO2RR) for CH4 production presents a promising strategy to address carbon neutrality, and the incorporation of a second metal has been proven effective in enhancing catalyst performance. Nevertheless, there remains limited comprehension regarding the fundamental factors responsible for the improved performance. Herein, the critical role of Pd in electrocatalytic CO2 reduction to CH4 on Cu-based catalysts has been revealed at a molecular level using in situ surface-enhanced Raman spectroscopy (SERS).

Promotion of Dentin Biomimetic Mineralization and Bonding Efficacy by Interfacial Control of an Experimental Citric Acid Dental Etching Agent.

Resin-bonded restorations are the most important caries treatment method in clinical practice. Thus, improving the durability of dentin bonding remains a pressing issue. As a promising solution, guided tissue remineralization can induce the formation of apatite nanocrystals to repair defects in the dentin bonding interface.

Synergistic Effects of TiO and Carbon Black for Water Evaporation-Induced Electricity Generation.

Water evaporation-induced electricity generators (WEGs) have drawn widespread attention in the field of hydrovoltaic technology, which can convert atmospheric thermal energy into sustainable electric power. However, it is restricted in the wide application of WEGs due to the low power output, complex fabrication process, and high cost. Herein, we present a simple and effective approach to fabricate TiO-carbon black film-based WEGs (TC-WEGs).

Identification of Lydicamycins as Main Antioomycete Compounds from the Biocontrol Agent sp. NEAU-S7GS2.

Oomycetes are well-known phytopathogens that seriously threaten many important crops worldwide. In this study, the endophytic actinobacterium sp. NEAU-S7GS2 demonstrated significant antagonistic activity against and and showed a potent biocontrol effect on suppression of soybean phytophthora root rot and pepper phytophthora blight.

Highly Stable Lithium Metal Batteries Enabled by Tuning the Molecular Polarity of Diluents in Localized High-Concentration Electrolytes.

Electrolyte plays a crucial role in ensuring stable operation of lithium metal batteries (LMBs). Localized high-concentration electrolytes (LHCEs) have the potential to form a robust solid-electrolyte interphase (SEI) and mitigate Li dendrite growth, making them a highly promising electrolyte option. However, the principles governing the selection of diluents, a crucial component in LHCE, have not been clearly determined, hampering the advancement of such a type of electrolyte systems.

Synergistic effect of ion-releasing fillers on the remineralization and mechanical properties of resin-dentin bonding interfaces.

In modern restorative dentistry, adhesive resin materials are vital for achieving minimally invasive, esthetic, and tooth-preserving restorations. However, exposed collagen fibers are found in the hybrid layer of the resin-dentin bonding interface due to incomplete resin penetration. As a result, the hybrid layer is susceptible to attack by internal and external factors such as hydrolysis and enzymatic degradation, and the durability of dentin bonding remains limited.

Thymic tuft cells: potential "regulators" of non-mucosal tissue development and immune response.

As the leading central immune organ, the thymus is where T cells differentiate and mature, and plays an essential regulatory role in the adaptive immune response. Tuft cells, as chemosensory cells, were first found in rat tracheal epithelial, later gradually confirmed to exist in various mucosal and non-mucosal tissues. Although tuft cells are epithelial-derived, because of their wide heterogeneity, they show functions similar to cholinergic and immune cells in addition to chemosensory ability.

Older Adults' Health Care Utilization a Year After Experiencing Fear or Distress from Hurricane Sandy.

Objective: To determine whether self-reports of disaster-related psychological distress predict older adults' health care utilization during the year after Hurricane Sandy, which hit New Jersey on October 29, 2012.

Methods: Respondents were from the ORANJ BOWL Study, a random-digit dialed sample from New Jersey recruited from 2006 to 2008. Medicare hospital, emergency department (ED) and outpatient claims data from 2012 and 2013 were matched to 1607 people age 65 and older in 2012 who responded to follow-up surveys conducted from July 2013 to July 2015 to determine their hurricane-related experiences.

Preoperative Sleep Disruption and Postoperative Delirium.

Study Objectives: To describe preoperative and postoperative sleep disruption and its relationship to postoperative delirium.
