Objectives: This study aims to investigate the possible role of non-steroidal anti-inflammatory drug-activated gene-1 (NAG-1) in nasal polyp development.
Patients And Methods: Twenty-one patients (15 males, 6 females; mean age 44.3 years; range 16 to 65 years) who underwent endoscopic sinus surgery for nasal polyposis (NP) were included in the study. Inferior turbinate mucosa samples were taken in addition to the polyp tissue which was already removed during routine procedure. The NAG-1 gene messenger ribonucleic acid (mRNA) expression levels of the polyp tissue and healthy turbinate mucosa were examined by real-time polymerase chain reaction (PCR). Patients were divided into two groups based on the presence or absence of comorbid asthma.
Results: The NAG-1 gene expression of the polyp tissue was 1,089 fold higher, compared to the healthy nasal mucosa (p=0.757). The NAG-1 mRNA levels were 2.13 times decreased in the patients with comorbid asthma (p=0.275). There was no statistically significant difference between the groups.
Conclusion: With the findings of this study NAG-1 gene may play a role in nasal polyp development in the presence of comorbid asthma.

Background: Thymic stromal lymphopoietin (TSLP) plays an important role in mediating the type-2-inflammatory response. This study examined how TSLP and interleukin (IL)-4 levels in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) correlated with clinical and postoperative outcomes.
Methods: Solid-phase sandwich ELISA was used to analyze TSLP and IL-4 levels in mucus (n = 47), plasma (n = 17), polyp (n = 30), inferior (n = 25), and middle (n = 26) turbinate tissue collected during functional endoscopic sinus surgery (FESS) in CRSwNP patients (n = 76) and controls (n = 11).

Introduction: Tissue eosinophil counts (TEC) might serve as a biomarker linking chronic rhinosinusitis (CRS) and the presence of adult-onset asthma. This study aimed to determine if TEC in sinus mucosa/polyps in CRS patients is an independent indicator of asthma and to identify its optimal cut-off point.
Methods: This cross-sectional study was conducted on primary CRS patients scheduled for surgery.

The microbiota stability, diversity, and composition are pillars for an efficient and beneficial symbiotic relationship between its host and itself. Microbial dysbiosis, a condition where a homeostatic bacterial community is disturbed by acute or chronic events, is a predisposition for many diseases, including local and systemic inflammation that leads to metabolic syndrome, diabetes, and some types of cancers. Classical dysbiosis occurs in the large intestine.

Sinonasal squamous cell carcinoma (SNSCC) is a rare tumor with a high 5-year mortality rate. However, proteomic technologies have not yet been utilized to identify SNSCC-associated proteins, which could be used as biomarkers. In this study, we aimed to discover a biomarker to predict SNSCC patients using proteomic analysis integrated with machine learning models.
