Macrophages in dental pulp: dynamic regulators of microenvironmental homeostasis and therapeutic targets in pulpitis

Abstract The dental pulp is a soft connective tissue enclosed by mineralized dentin, containing odontoblasts, dental pulp stem cells (DPSCs), fibroblasts, endothelial cells, nerves, and immune cells. Under physiological and pathological conditions, these cells collectively regula...

Pan-retinal pathology detection in oct scans integrating natural language synthesis with diagnostic annotation

Abstract While OCT is pivotal for macular disease diagnosis, its adoption in primary care is limited by AI systems that cannot simultaneously analyze multi-sectional scans across the full spectrum of maculopathies or generate diagnostically integrated reports. Here we present iOC...

<title>Abstract</title> Objective To investigate masticatory muscle activity and mandibular border movement in adolescents with skeletal class II malocclusion and mandibular retrognathia and explore the influence of mandibular retrognathia on masticatory system function. Methods...

Isolated Myeloid Sarcoma of the Thoracic Spine as Initial Presentation of Acute Promyelocytic Leukemia: A Case Report and Literature Review

Introduction: Acute promyelocytic leukemia (APL), a subtype of acute myeloid leukemia, typically presents with severe bleeding. However, the occurrence of APL with isolated myeloid sarcoma (MS) as the sole initial presentation is extremely rare, lacking typical clinical and labor...

Insomnia severity predicts suicide attempts in youth with depression in China: a 6-month prospective cohort study

Evidence linking insomnia to suicidal risk in depressed youth is largely cross-sectional, limiting inference about temporal direction. We examined whether baseline insomnia severity predicts subsequent suicide attempts in this population. We conducted a 6-month prospective cohort...

The TLR9-CXCL2 complex orchestrates mitochondrial DNA-driven regulatory B cell dysfunction in acute lung injury

Acute lung injury (ALI)/Acute respiratory distress syndrome (ARDS) is a lethal condition driven by unresolved inflammation. Circulating mitochondrial DNA (mtDNA) acts as a potent damage-associated molecular pattern, yet its direct role in disrupting adaptive immune checkpoints re...
