Article Abstract
This study aimed to investigate the applicability of plasma extracellular vesicles (EVs) miR-99a-5p as a potential head and neck squamous cell carcinoma (HNSCC) diagnostic biomarker. The miRNA expression of HNSCC tissue and plasma EVs were profiled by small RNA sequencing. qRT-PCR was performed to detect miR-99a-5p expression in HNSCC ( = 93) and benign disease ( = 39) plasma EVs and formalin-fixed and paraffin-embedded (FFPE) tissue ( = 110). We constructed receiver-operating characteristic curves to investigate the diagnostic efficiency of plasma EVs miR-99a-5p. Tumor tissue exhibited lower miR-99a-5p than para-tumor tissue. Patients with high miR-99a-5p expression exhibited significantly more p16 positive status. In contrast, HNSCC plasma EVs harbored more miR-99a-5p than the benign disease group. Plasma EVs miR-99a-5p distinguished HNSCC with area under the curve (AUC) of 0.7494 (95% CI: 0.6692-0.8296; < 0.0001), with 61.54% sensitivity and 75.27% specificity, respectively. Furthermore, plasma EVs miR-99a-5p also distinguished early HNSCC with AUC of 0.7394 (95% CI: 0.6284-0.8504; = 0.0002), with 79.07% sensitivity and 61.54% specificity, respectively. Plasma EVs miR-99a-5p is a potential biomarker for predicting early HNSCC.

Background: High % of low-voltage area (LVA), a surrogate of scar, is associated with atrial fibrillation (AF) recurrence after pulmonary vein isolation (PVI). Noninvasive biomarkers of LVA are a medical need for PVI decision.
Objective: We aimed to identify the proteome profile of plasma extracellular vesicles (EVs) associated with high % LVA, their cellular origin, and their regulation by hyperglycemia.

Background: Sarcopenia is a complex, multifactorial condition characterized by progressive loss of muscle mass, strength, and function. Despite growing awareness, the early diagnosis and pathophysiological characterization of this condition remain challenging due to the lack of integrative biomarkers.
Objective: This study aimed to conduct a comprehensive multilevel profiling of clinical parameters, immune cell phenotypes, extracellular vesicle (EV) signatures, and biochemical markers to elucidate biological gradients associated with different stages of sarcopenia.

Nano-sized extracellular vesicles (EVs) possess a lipid bilayer and are secreted from cells into their surrounding environment. The transport of multiple biomolecules, including DNA together with RNA, microRNAs (miRNAs), lipids, proteins, and metabolites, happens through biofluids via EVs for intercellular communication. Extracellular vesicles play crucial roles during the embryo production (IVEP) process.

Tenrecs are heterothermic burrowing mammals, which are capable of withstanding extreme environmental stressors, including during hibernation. Their phylogenetic position as reminiscent of an ancestral placental mammal makes tenrecs a unique model for evolutionarily conserved traits, with potential translatability to human physiology and pathobiology, including adaptations to extreme environments. In this study, we compared tenrec plasma for post-translational protein citrullination profiles (citrullinomes) and extracellular vesicle (EV) characteristics, including selected microRNA cargoes (miR-21, miR-155, miR-206, miR-210), between baseline active and hibernating states at low (12 °C) and high (28 °C) ambient temperatures.

Billions of cells undergo apoptosis, a non-inflammatory form of programmed cell death, daily as part of normal development and homeostasis. Apoptotic cells undergo apoptotic cell disassembly to release large extracellular vesicles (EVs) called apoptotic bodies (ApoBDs) to promote dead cell clearance, or otherwise proceed to an inflammatory, lytic outcome (i.e.
