Elevation of S100 calcium‑binding protein A7 in recurrent pterygium

Calcium-binding S100 protein expression in pterygium

PURPOSE Pterygium is an ocular surface disease of unknown etiology associated with epithelial and fibrovascular outgrowth from the conjunctiva onto the cornea. S100 proteins are calcium-activated signaling proteins that interact with other proteins to modulate biological functions such as cell migration, proliferation, and differentiation. The aim of this study was to investigate the presence o...

Expression of calcium binding protein S100 A7 (psoriasin) in laryngeal carcinoma.

UNLABELLED Many studies have reported increased expression of S100 A7 (psoriasin) in neoplastic lesions. Among them are studies on breast carcinoma, bladder squamous cell carcinoma, skin tumors and oral cavity squamous cell carcinoma. The expression of S100 A7 has not been described for laryngeal cancer. OBJECTIVE This study aims to identify the expression of the calcium-binding protein S100 ...

Elevation of human alpha-defensins and S100 calcium-binding proteins A8 and A9 in tear fluid of patients with pterygium.

PURPOSE The pathogenesis of pterygia is still not well understood. Recent studies suggest that it may be associated with inflammation and progressive proliferation triggered by ultraviolet radiation. In this study the authors determined that the inflammatory nature of pterygium is reflected in the protein components of tears. METHODS Consent for this study was obtained from 12 patients (avera...

Dose Assessment of Phosphorus-32 (32P) for the Treatment of Recurrent Pterygium

Introduction Pterygium is a wing-shaped, vascular, fleshy growth that originates from the conjunctiva and can spread into the corneal limbus and beyond. Beta irradiation after bare sclera surgery of primary pterygium is a simple, effective, and safe treatment, which reduces the risk of local recurrence. Materials and Methods Dosimetric components of strontium-90 (90Sr), phosphorous-32 (32P), an...
