C3-epi-25(OH)D3 percentage, not level, may be a potential biomarker to reflect its pathological increase in multiple diseases: a cross-sectional case–control study

Scientific Reports, 2023
National surveys in developed countries have examined the presence of C3-epimer of 25-hydroxyvitamin D3 [C3-epi-25(OH)D3]. However, controversy remains regarding its association with disease occurrence due to its high correlation with 25-hydroxyvitamin ...

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Molecular Biomarkers in Meniere's Disease: A Scoping Review of Current Evidence

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Meniere's disease is a complex chronic inner ear condition that is characterized by vertigo, tinnitus, aural fullness, and progressive hearing loss. Currently, diagnostic strategies remain symptom‐driven, and treatments focus on management of discrete episodes rather than targeting underlying pathophysiology.

Hypovitaminosis D in acute inpatient cancer rehabilitation: Prevalence, predictors, and practical implications

PM&R, EarlyView.
Abstract Background Hypovitaminosis D is associated with adverse health outcomes, including increased mortality in patients with cancer. Although vitamin D insufficiency (23%–72%) and deficiency (20%–71%) are common among patients admitted to inpatient rehabilitation, their prevalence and predictors in cancer‐specific inpatient rehabilitation ...

Multi‐Omics Analysis Reveals Vitamin D Metabolism, Hyper‐IgE Genes, and Epithelial Barrier Dysfunction in Hazelnut Allergy

Allergy, EarlyView.
Multi‐omics profiling of hazelnut‐allergic versus nonallergic individuals identified 87 differentially methylated signals, 125 differentially expressed genes, and 11 differentially secreted proteins. Among these were ZNF341 and ARL2 (STAT3‐mediated hyper‐IgE dysregulation), alongside epithelial barrier (TRIM31, TRIM40, CDSN) and vitamin D pathway ...
