Insights into laryngeal Castleman disease: A comprehensive scoping review with a case study focus.

Introduction: Castleman disease (CD) refers to a heterogeneous group of lymphoproliferative disorders, which rarely involves the larynx. Our goal in this study is to elucidate the clinical presentation, diagnostic techniques, and treatment methods of laryngeal CD through a scoping review and the addition of a new case.

Methods: Due to limited existing literature, we employed a mixed methodology for review.

Docosahexaenoic Acid Controls Pulmonary Macrophage Lipid Raft Size and Inflammation.

Background: Docosahexaenoic acid (DHA) controls the biophysical organization of plasma membrane sphingolipid/cholesterol-enriched lipid rafts to exert anti-inflammatory effects, particularly in lymphocytes. However, the impact of DHA on the spatial arrangement of alveolar macrophage lipid rafts and inflammation is unknown.

Objectives: The primary objective was to determine how DHA controls lipid raft organization and function of alveolar macrophages.

A Highly Ordered Nitroxide Side Chain for Distance Mapping and Monitoring Slow Structural Fluctuations in Proteins.

Unlabelled: Site-directed spin labeling electron paramagnetic resonance (SDSL-EPR) is an established tool for exploring protein structure and dynamics. Although nitroxide side chains attached to a single cysteine via a disulfide linkage are commonly employed in SDSL-EPR, their internal flexibility complicates applications to monitor slow internal motions in proteins and to structure determination by distance mapping. Moreover, the labile disulfide linkage prohibits the use of reducing agents often needed for protein stability.

Submucosal Epstein-Barr Virus Positive Polymorphic B-cell Lymphoproliferative Disorder of the Larynx: A Case Report.

Epstein-Barr virus (EBV) belongs to the group of human herpes virus and can cause clinical and subclinical infections. Although EBV-related disease presentations are similar, they can lead to oncogenic transformation with various clinical manifestations. A thorough workup with morphology, immunohistochemistry, and molecular studies is crucial for the diagnosis of EBV-positive polymorphic B-cell lymphoproliferative disorder, not otherwise specified (NOS), which is a new entity introduced by International Consensus Classification in 2022.
