Nasoalveolar Cyst

Abstract

Nasoalveolar cyst is a nonodontogenic, soft tissue cyst characterized by its extraosseous location in the nasal alar region. It is synonymous with nasolabial cyst, nasal vestibule cyst, nasal wing cyst and mucoid cyst of the nose. It also called Klestadt's cyst. In this study, we would like to highlight the clinical presentation and the radiological features of nasolabial cyst in order to assist other healthcare providers in the diagnosis and treatment of this uncommon entity.

Oxidation and Reduction

“…132 The Ir(III)-catalysed oxidation of l-phenylalanine (Phe) to phenylpyruvic acid was first order in OH − and the order with respect to Phe changed from first order to zero order with increasing Phe concentration. 133 The Os(VIII)-catalysed oxidation of l-cystine was first order in Os(VIII) and OH − and zero order in cysteine; formation of an intermediate complex by OsO 4 (OH) 2 2− and Fe(CN) 6 3− ions has been proposed. 134 The oxidation of thioglycolic and thiomalic acids to disulfides in acidic medium was first order in substrates and H + ; a radical intermediate in thiomalic acid oxidation was characterized as a 1 : 2 : 1 triplet.…”
