introduction: mucous retention cysts are a subtype of intracordal vocal cysts that may occur spontaneously or may be associated with poor vocal hygiene, and which require optimal treatment. the objective of this study was to present a new laser-assisted microsurgery technique for treating intracordal mucous retention cysts and to describe the final outcomes.   materials and methods: in this pro...

BACKGROUND Tracheal defects may occur after trauma or prolonged intubation. Resection of tracheal tumors also poses a major challenge for substitution. In an effort to solve this problem, different techniques have been tried with little success. We report on a new animal model which showed acceptable results with fewer complications. METHODS We replaced 5 cm of cervical trachea in 10 dogs wit...

Introduction Papillomaviruses (PVs) can cause hyperplasia in the skin and mucous membranes of humans, mammals, non-mammalian animals, are a significant risk factor for cervical genital cancers. Methods Using next-generation sequencing (NGS), we identified two novel strains papillomavirus, PV-HMU-1 PV-HMU-2, swabs taken from belugas ( Delphinapterus leucas ) at Polar Ocean Parks Qingdao Dalian. ...

we evaluated the specific pattern of pre- and postoperative neurological signs and symptoms of cervical spondylotic myelopathy (csm) to determine [mdings which had a predictive value for surgical outcome. consecutive patients with csm caused by osteophytic ridge or intervertebral disc herniation who underwent anterior cervical decompression and fusion in loghman hakim hospital from 1999-2003 we...

THIS paper is an account of the clinical and pathological features and the response to treatment of 80 mucous gland tumours derived from sites other than the major salivary glands. Tumours similar to those met with in the parotid gland are also encountered, though less frequently, in the submaxillary and sublingual glands and in the minor salivary glands which are distributed throughout the ora...

Mucous membrane plasmacytosis is a rare, idiopathic condition consisting of a dense plasma-cell infiltrate of the mucous membranes. Zoon first described a plasma-cell infiltrate occurring on the glans penis and plasmacytosis involving other body orifices have been reported under a variety of different terms. White et al. simplified the terminology by suggesting all plasma-cell infiltrates of th...

The airways are conduits that transport atmospheric oxygen to the distal alveolus. Normally, airway mucous cells are rare. However, diseases of the airway are often characterized by mucous metaplasia, in which there are dramatic increases in mucous cell numbers. As the Notch pathway is known to regulate cell fate in many contexts, we misexpressed the active intracellular domain of the mouse Not...

Exposure to ozone induces mucous cell metaplasia in rat airway epithelia. During the regeneration process, apoptotic mechanisms may be responsible for eliminating metaplastic cells. Therefore, the present study investigated expression of Bcl-2, a regulator of apoptosis, in ozone-induced mucous cell metaplasias. Adjacent metaplastic mucous cells in nasal airway epithelia that were exposed to ozo...
