A Closer Look at Metalloproteinases : Nova Science Publishers : 9781536165173 : 1536165174 : 01 Feb 2020 : "A Closer Look at Metalloproteinases first presents an analysis of the matrix metalloproteinases system in two common neurodegenerative disorders, namely age-related macular degeneration and Alzheimer's disease. Next, this collection aims to evaluate theexpression of matrix metalloproteinase-9 in nasopharyngeal carcinoma patients. The cross-sectional analytic study enrolled 106 patients with nasopharyngeal carcinoma based on radiologic and histopathological examination. The patient never underwent radiotherapy, chemotherapy and/or a combination. Matrix metalloproteinase-9 was assessed using immunohistochemical staining of matrix metalloproteinase-9 in the anatomic pathology department. The authors go on to discuss the matrix metalloproteinases family, their structural organization, functions and role in cardiovascular disease. Data about the role of matrix metalloproteinases in th
