Exhaled nitric oxide from lung periphery is increased in COPD.
Single constant flow exhaled nitric oxide (eNO) cannot distinguish between the sources of NO. The present study measured eNO at multiple expired flows (MEFeNO) to partition NO into alveolar (Calv,NO) and bronchial (Jaw,NO) fractions to investigate peripheral lung contribution to eNO in chronic obstructive lung disease (COPD). MEFeNO were made in 81 subjects including 18 nonsmokers, 16 smokers a...
متن کاملExpression of Matrix Metalloproteinase-2 and -9 in Meningioma
Background: Meningioma is one of the most common tumors of the central nervous system. It was shown that meningioma had up-regulated expression of Matrix Metalloproteinases (MMPs) that involved in cell growth, angiogenesis and metastasis. Objectives: The aim of the study was the assessment of serum MMP-2 and -9 levels in patients with different grades of meningioma. Materials & Me...
متن کاملroles of osteopontin and matrix metalloproteinase-7 in occurrence, progression, and prognosis of nonsmall cell lung cancer
background: this study detected osteopontin (opn) and matrix metalloproteinase-7 (mmp-7) expressions to explore the roles of opn and mmp-7 in the occurrence, progression, and prognosis of nonsmall cell lung cancer (nsclc). materials and methods: a retrospective study was conducted on nsclc tissues ( n = 152; case group) and adjacent nonneoplastic lung parenchyma (adjacent to tumor >5 cm; n = 15...
متن کاملElevated Expression of Matrix Metalloproteinase-9 not Matrix Metalloproteinase-2 Contributes to Progression of Extracranial Arteriovenous Malformation
Extracranial arteriovenous malformations (AVMs) are rare but dangerous congenital lesions arising from direct arterial-venous shunts without intervening capillaries. Progressive infiltration, expansion, and soft tissue destruction lead to bleeding, pain, debilitation and disfigurement. The pathophysiology of AVMs is not well understood. Matrix Metalloproteinases (MMPs) are thought to play an im...
متن کاملMatrix metalloproteinase-2 is expressed in melanoma-associated spongiform scleropathy.
PURPOSE To correlate the expression of matrix metalloproteinases (MMPs) with melanoma-associated spongiform scleropathy (MASS) and scleral tumor invasion in eyes with uveal melanoma. METHODS Eleven specimens with MASS and 11 eyes without MASS were investigated. Sections were examined for MMP-1, -2, -9, and -13 mRNA expression by in situ hybridization with (35)S-radiolabeled riboprobes. Immuno...
