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...

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;...

BACKGROUND Diabetes mellitus (DM) is a chronic disease of the carbohydrate metabolism that, when not rigorously controlled, compromises systemic and organ integrity, thereby causing renal diseases, blindness, neuropathy, arteriosclerosis, infections, and glandular dysfunction, including the salivary glands. The aim of this study was to determine the relationship between the qualitative and quan...

OBJECTIVE Statins are widely used lipid-lowering drugs, which have pleiotropic effects, such as anti-inflammation, and vascular protection. In our study, we investigated the radioprotective potential of simvastatin (SIM) in a murine model of radiation-induced salivary gland dysfunction. DESIGN Ninety-six Institute of Cancer Research mice were randomly divided into four groups: solvent + sham ...

abstract salivary gland tumors are among the pathologies in the head and neck that may be challenging in diagnosis and treatment. most benign tumors occur in the parotid gland. pleomorphic adenoma is the most common type. basal cell adenoma is a subtype of the monomorphic adenoma with rare occurrence. proper diagnosis and clinical evaluation by the use of radiography can lead the physician to t...

Radiotherapy is the primary treatment for patients with head and neck cancer, which account for roughly 500,000 annual cases worldwide. Dysfunction of the salivary glands and associated conditions like xerostomia and dysphagia are often developed by these patients, greatly diminishing their life quality. Current preventative and palliative care fail to deliver an improvement in the quality of l...

Salivary gland cancers are uncommon malignancies of the head and neck region. Their site of origin can be major (parotid, submandibular and sublingual) or minor salivary gland (palate, nasal cavity, paranasal sinuses, trachea and lacrimal gland). Of all the salivary gland neoplasms, 85% are benign and 15% are malignant. Salivary gland malignancies comprise 3-6% of all head and neck cancers (Pin...

This study was designed to compare labial and sublingual salivary gland biopsies in the diagnosis of Sjögren's syndrome (SS). Fourteen labial and 29 sublingual specimens were considered positive. There was a better correlation between infiltration of the ductal structure and the focus score in the sublingual salivary gland biopsy than in the labial salivary gland biopsy. Use of sublingual saliv...

The involvement of reactive oxygen species (ROS) in the pathophysiology of Sjögren's syndrome (SS), an autoimmune disorder, and irradiation-induced impairments in salivary secretion has been reported. Meanwhile, the strong antioxidant astaxanthin (Ast) has been suggested to have therapeutic effects on various diseases. In the present study, we examined the ROS scavenging capacity of Ast using a...

adenoid cystic carcinoma is an uncommon, slow growing malignant salivary gland tumor that is characterized by wide local infiltration, perineural spread, propensity to local recurrence anddistant metastasis. in this paper, the authors present a case of adenoid cystic carcinoma affecting the palate and involving the maxillary sinus in a 60‑year‑old male patient along with a brief reviewof litera...
