Sjögren’s syndrome (SS) is an autoimmune disease in which exocrine glands including the salivary gland are targeted and destroyed by the immune system (Voulgarelis and Tzioufas, 2010). SS and the side-effects of γ-radiation therapies for head and neck cancers cause salivary gland dysfunction, in particular hyposalivation (Atkinson et al., 2005; Fox, 1998; O'Sullivan and Higginson, 2010). Among ...
Salivary gland tumors are uncommon within children and when they do arise, they mainly affect the major salivary glands. Minor salivary gland tumors are rare in children, which are responsible for less than 10% of all the cases. Pleomorphic adenoma is the most common tumor of the sa...
Transcription factors drive organogenesis, from the initiation of cell fate decisions to the maintenance and implementation of these decisions. The Drosophila embryonic salivary gland provides an excellent platform for unraveling the underlying transcriptional networks of organ development because Drosophila is relatively unencumbered by significant genetic redundancy. The highly conserved FoxA...
OBJECTIVE Uptake of 99mTc-pertechnetate in salivary glands reflects intact salivary gland parenchyma. However, no standardized protocol for an accurate quantification of parenchymal function has been established so far. METHODS In this paper we report on a validated acquisition protocol supplying a normal database for standardized quantitative salivary gland scintigraphy. RESULTS The major ...
Facial palsy, salivary leakage and postoperative bleeding are the main complications in parotid gland surgery. To find ways to reduce the occurrence of these complications, we compare traditional methods using the hand-tie ligation technique with a bipolar electrode knife against LigaSureTM Small Jaw, a newly developed vessel sealing device, in parotid gland operations. Eighteen parotid gland t...
The Drosophila salivary gland is proving to be an excellent experimental system for understanding how cells commit to specific developmental programs and, once committed, how cells implement such decisions. Through genetic studies, the factors that determine where salivary glands will form, the number of cells committed to a salivary gland fate, and the distinction between the two major cell ty...
Saliva plays an essential role in maintaining oral health. Alterations in salivary function lead to compromise of oral tissues and functions and have a large impact on a patient’s quality of life. Reductions in salivary flow most commonly manifest as symptoms of oral dryness. This subjective complaint of dry mouth is termed xerostomia, whereas objective alterations in salivary performance, quan...
Naphthyl esterase and platelet-activating factor (PAF)-acetylhydrolase activities were detected in the salivary glands of the cat flea, Ctenocephalides felis. Salivary naphthyl esterase activity is disgorged during exploratory probing. Whole extracts of salivary glands contain esterase activity against the short-chain naphthyl esters alpha-naphthyl acetate (approximately 210pmol/min/gland pair;...
AIM To examine the role of Epstein-Barr virus (EBV) in lymphoepithelial carcinoma of the salivary gland in Hong Kong Chinese. METHODS Ten cases of lymphoepithelial carcinoma of the salivary gland (eight parotid and two submandibular) were examined. In situ hybridisation was used to localise EBER RNA, immunohistochemical methods to detect expression of latent membrane protein 1 (LMP-1) in EBV ...
