Visual and mental fatigues induced by active shutter stereoscopic 3D (S3D) display have been reported using event-related brain potentials (ERP). An important question, that is whether such effects (visual & mental fatigues) can be found in passive polarized S3D display, is answered here. Sixty-eight healthy participants are divided into 2D and S3D groups and subjected to an oddball paradigm after being exposed to S3D videos with passive polarized display or 2D display. The age and fluid intelligence ability of the participants are controlled between the groups. ERP results do not show any significant differences between S3D and 2D groups to find the aftereffects of S3D in terms of visual and mental fatigues. Hence, we conclude that passive polarized S3D display technology may not induce visual and/or mental fatigue which may increase the cognitive load and suppress the ERP components.

Epithelial fusion is a fundamental morphogenetic process critical for the closure and compartmentalisation of developing organs. While widely studied in systems such as neural tube and palatal closure, the cellular transitions that enable fusion remain poorly understood. Here, we investigate epithelial fusion during chick otic vesicle (OV) closure and identify a transient population of cells at the epithelial interface that mediate this process.

Background: This study investigated the role of UVB radiation and the influence of a simulated passive barrier on the enzymatic conversion of 25-hydroxyvitamin D3 (25(OH)D) by 1-alpha hydroxylase and its effects on the functional activity of tissue-resident macrophages.
Methods: Murine peritoneal tissue-resident macrophages (PRMφs) were exposed to three conditions: (1) Baseline (Control group), with no light exposure; (2) UVB+/RF- group, exposed to UVB rays without passive barrier simulation; (3) UVB+/RF+ group, UVB exposure with a thin layer of rat fur to mimic the passive barrier on the skin.
Results: UVB exposure did not significantly alter 25OHD levels across groups but led to a marked downregulation of 1-alpha hydroxylase, particularly with the simulated barrier.

Immune thrombocytopenia (ITP) is a heterogeneous autoimmune disorder characterized by immune-mediated destruction of platelets and impaired platelet production. Although autoantibodies have historically been central to the understanding of ITP, current evidence demonstrates that its pathogenesis extends well beyond humoral mechanisms to involve complex dysregulation of both innate and adaptive immune responses. Multiple immune pathways-including autoreactive B and T cells, dendritic cell activation, and regulatory T cell deficiency-contribute to disease onset, progression, and chronicity.

Phonon polaritons─quasiparticles formed by coupling infrared (IR) photons with optical phonons in polar materials─enable highly confined light-matter interactions with lower losses than those of plasmonic systems. Although they have been successfully exploited for enhanced mid-IR chemical sensing in solid- and liquid-phase environments, their application in gas-phase detection remains largely underexplored. Here, we introduce a low-loss phonon polariton platform based on planar Pd/SiC heterostructures and nanostructured Pd/SiC metasurfaces for enhanced mid-IR gas detection.

Early bone defect regeneration remains a major clinical challenge owing to a compromised osteogenic microenvironment characterized by insufficient mineralization and immature collagen deposition, which severely impede mechanical stability. Although conventional guided bone regeneration (GBR) membranes provide passive barrier functions, their lack of dynamic immune response regulation often leads to delayed ossification. To address this critical gap, a plasma-treated polycaprolactone (PT-PCL) electrospun nanofiber membrane functionalized with ultrasound sequentially extruded stromal vascular fraction chimeric vesicles (USE-SCNVs) is developed.
