Identification and Validation of Biomarkers in Chronic Rhinosinusitis With Nasal Polyps and Study of Their Associated Mechanisms

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Cell senescence (CS) and lipid metabolism (LM) disorders have been reported in chronic rhinosinusitis with nasal polyps (CRSwNP). However, the mechanism is still unclear. Methods Data were obtained from public databases; differential expression analysis and machine learning were performed to identify biomarkers and to understand the

Research Progress on Upper Airway Cough Syndrome

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Upper airway cough syndrome (UACS) has been identified as a significant contributor to chronic cough in various national guidelines. However, the complexity of its pathogenesis, the lack of clarity surrounding its diagnostic criteria, and its overlap with other etiologies of chronic cough present considerable challenges in both diagnosis and ...

A study of cell membranes in nasal epithelial cells from patients with chronic rhinosinusitis with nasal polyps by means of a fluorescent probe [PDF]

, 2009
Aim. To assess the state of membranes in nasal epithelial cells obtained from the patients with chronic rhinosinusitis with nasal polyps (CRSwNP) with the help of the fluorescent probe 2-(2ʹ-ОН-phenyl)-5-phenyl-1,3-oxazole. Methods. The state of membrane

Effects of Aging on Nasal Mucociliary Clearance

An International Journal Clinical Rhinology, 2011
ABSTRACT Nasal mucociliary clearance is a primary physiological defense mechanism of upper as well as lower respiratory tract, and thus maintains the state of health of the respiratory tract. Any disturbance in number or movement of cilia and change in character or amount of mucus production leads to an altered nasal mucociliary clearance.

Club Cells in Nasal Epithelial Repair: Insights From an IL‐13‐Induced Inflammatory Model

Allergy, EarlyView.
Four inflammatory endotypes of CRSwNP, defined by eosinophil and neutrophil infiltration, show distinct patterns of basal, club, ciliated, and goblet cell expression in nasal epithelium. Using an ALI‐HNECs model, we demonstrate that IL‐13 impairs mucociliary function by promoting club‐to‐goblet cell differentiation while inhibiting club‐to‐ciliated ...

Saline nasal irrigation for acute upper respiratory tract infections (Review) [PDF]

, 2015
BACKGROUND: Acute upper respiratory tract infections (URTIs), including the common cold and rhinosinusitis, are common afflictions that cause discomfort and debilitation and contribute significantly to workplace absenteeism.

Effect of Gender on Nasal Mucociliary Clearance

International Journal of Biomedical Research, 2015
Background: The sexual dimorphism favours gender specific biological characteristics influenced by sex hormones. These sex hormones determined differences influence the health of an individual by influencing many physiological parameters. As the pulmonary functions are different between male and female and the susceptibility to different respiratory ...

Elevated CO2 and Temperature Alter Grass Pollen's Ability to Modify Transcriptome and Function of the Nasal Epithelium

Allergy, EarlyView.
We exposed human nasal epithelial tissues to pollen from grasses grown under different climate treatments (temperature and CO2). Pollen weakened epithelial tight junctions and altered cytokine‐related gene expression, with similar protein‐level effects.

Effect of packing on nasal mucosa of sheep [PDF]

, 2000
The effects of packing with ribbon gauze and neuropatties on the nasal mucosa was assessed using sheep as an animal model. Fourteen sheep either underwent ribbon gauze or neuropattie nasal packing.
