Matrix Metalloproteinase-9 Expression and Status of Cervical Lymph Nodes in Patients with Nasopharyngeal Carcinoma.

Tumor growth and metastasis in nasopharyngeal carcinoma (NPC) patients was suspected as a role of several molecular biomarkers that have been identified in tumor specimens of patients with NPC. Invasion and metastasis process was a complex mechanism which involved some proteolytic enzymes, such as matrix metalloproteinase-9 (MMP-9). To analyze the association of MMP-9 expression of NPC patients with cervical lymph node metastasis.

The Relationship between Serum Vitamin D Levels with Allergic Rhinitis Incidence and Total Nasal Symptom Score in Allergic Rhinitis Patients.

Background: Allergic diseases and vitamin D deficiency were found to have a relationship. However, there was limited number of studies on the relationship between vitamin D with allergic rhinitis (AR) and total nasal symptom scores (TNSS), particularly in determining the cut-off points of serum vitamin D levels which correlated to AR.

Aim: As this particular study has never been conducted in Indonesia, the main objective of this study was to investigate this issue.
