Comparative study regarding the stability of a proximal ulnar stump with or without distal oblique bundle reconstruction during the Sauvé‒Kapandji procedure: a finite-element analysis.

Background: The most common postoperative complication of the Sauvé‒Kapandji (S-K) procedure is proximal ulnar stump instability. The distal oblique bundle (DOB) is a stable tissue used to stabilize the distal radioulnar joint. This study created finite-element models of the distal oblique bundle (DOB) to determine its effect on the proximal ulnar stump instability encountered during the Sauvé‒Kapandji procedure.

Association of Organophosphorus Pesticide and Glyphosate Exposure with Nasal Flora and Total IgE in Solar Greenhouse Workers: A Unique Farmer Group.

Studies have shown that the presence of allergens, including insecticides, significantly increases the risk of occupational allergic diseases among solar greenhouse workers. However, no studies have yet investigated the relationship between organophosphorus pesticide use by greenhouse workers and allergic diseases, and the role of the flora in this context remains unclear. Therefore, this study aimed to investigate the relationship between combined exposure to organophosphorus pesticides (OPs) and Glyphosate (GLY) and changes in total immunoglobulin E (IgE) levels, as well as to analyze the role of nasal flora in allergic status.

Size effect-based improved antioxidant activity of selenium nanoparticles regulating Anti-PI3K-mTOR and Ras-MEK pathways for treating spinal cord injury to avoid hormone shock-induced immunosuppression.

Spinal cord injury (SCI) is a critical condition affecting the central nervous system that often has permanent and debilitating consequences, including secondary injuries. Oxidative damage and inflammation are critical factors in secondary pathological processes. Selenium nanoparticles have demonstrated significant antioxidative and anti-inflammatory properties via a non-immunosuppressive pathway; however, their clinical application has been limited by their inadequate stability and functionality to cross the blood-spinal cord barrier (BSCB).

Ferristatin II protects nucleus pulposus against degeneration through inhibiting ferroptosis and activating HIF-1α pathway mediated mitophagy.

Background: Nucleus pulposus (NP) degeneration represents a significant contributing factor in the pathogenesis of intervertebral disc (IVD) degeneration (IVDD), and is a key underlying mechanism in several lumbar spine pathologies. Nevertheless, the precise mechanisms that govern NP degeneration remain unclear. A significant contributing factor to IVDD has been identified as ferroptosis.

The Role of Oligodendrocyte Lineage Cells in the Pathogenesis of Alzheimer's Disease.

Alzheimer's disease (AD) is a central nervous system degenerative disease with a stealthy onset and a progressive course characterized by memory loss, cognitive dysfunction, and abnormal psychological and behavioral symptoms. However, the pathogenesis of AD remains elusive. An increasing number of studies have shown that oligodendrocyte progenitor cells (OPCs) and oligodendroglial lineage cells (OLGs), especially OPCs and mature oligodendrocytes (OLGs), which are derived from OPCs, play important roles in the pathogenesis of AD.

Identification of human cranio-maxillofacial skeletal stem cells for mandibular development.

Compared with long bone that arises from the mesoderm, the major portion of the maxillofacial bones and the front bone of the skull are derived from cranial neural crest cells and undergo intramembranous ossification. Human skeletal stem cells have been identified in embryonic and fetal long bones. Here, we describe a single-cell atlas of the human embryonic mandible and identify a population of cranio-maxillofacial skeletal stem cells (CMSSCs).

A Self-Powered Circularly Polarized Light Photodetector with High Responsivity Based on the Chiral Quasi-2D Perovskite Film.

Low-dimensional hybrid organic-inorganic perovskites (HOIPs) containing chiral organic ligands have recently emerged as promising candidates for circularly polarized light (CPL) detection, which can distinguish left- and right-handed CPL directly. However, the increase in responsivity and realization of self-powered CPL photodetector remain a challenge. Meanwhile, there is a trade-off between the photocurrent responsivity and the ability to differentially absorb CPL in detectors based on these low-dimensional perovskites.
