SFTPB in serum extracellular vesicles as a biomarker of progressive pulmonary fibrosis.

Progressive pulmonary fibrosis (PPF), defined as the worsening of various interstitial lung diseases (ILDs), currently lacks useful biomarkers. To identify novel biomarkers for early detection of patients at risk of PPF, we performed a proteomic analysis of serum extracellular vesicles (EVs). Notably, the identified candidate biomarkers were enriched for lung-derived proteins participating in fibrosis-related pathways.

Double-Bending Tension Band Wire for Olecranon Fractures: A Novel Technique.

Purpose: This retrospective study aimed to compare the clinical outcomes and complications of conventional tension band wire (TBW), TBW with penetrating technique, and double-bending technique.

Methods: A total of 40 patients (17 men and 23 women; mean age: 64.0 ± 19.

Galectin-10 in serum extracellular vesicles reflects asthma pathophysiology.

Background: Novel biomarkers (BMs) are urgently needed for bronchial asthma (BA) with various phenotypes and endotypes.

Objective: We sought to identify novel BMs reflecting tissue pathology from serum extracellular vesicles (EVs).

Methods: We performed data-independent acquisition of serum EVs from 4 healthy controls, 4 noneosinophilic asthma (NEA) patients, and 4 eosinophilic asthma (EA) patients to identify novel BMs for BA.

Secretion of mitochondrial DNA via exosomes promotes inflammation in Behçet's syndrome.

Mitochondrial DNA (mtDNA) leakage into the cytoplasm can occur when cells are exposed to noxious stimuli. Specific sensors recognize cytoplasmic mtDNA to promote cytokine production. Cytoplasmic mtDNA can also be secreted extracellularly, leading to sterile inflammation.
