Assessment of sympathoadrenal medullary system (SAM) activity is only possible to date via measurement of catecholamines in blood plasma or via electrophysiological methods. Both ways of measurement are restricted to endocrinological or psychophysiological laboratories, as both require either immediate freezing of blood samples or complex recording devices. Efforts have therefore been undertake...

OBJECTIVES Treatment of conditions that lead to salivary hypofunction, such as radiation induced xerostomia, is currently limited to the administration of saliva substitutes and sialogogues. The transient effect of these medications necessitates frequent administration, and systemic side effects may be intolerable. The creation of implantable, functional salivary gland tissue from autologous gl...

Saliva is a crucial biofluid for oral health and is also of increasing importance as a non-invasive source of disease biomarkers. Salivary alpha-amylase is an abundant protein in saliva, and changes in amylase expression have been previously associated with a variety of diseases and conditions. Salivary alpha-amylase is subject to a high diversity of post-translational modifications, including ...

CONTEXT Rib raising is an osteopathic manipulative treatment technique used to address restricted excursion of the rib cage and modulate sympathetic nervous system (SNS) activity. However, the physiologic effects of this technique have not been well documented. OBJECTIVE To investigate the effects of rib raising on the autonomic nervous system and the hypothalamic-pituitary-adrenal axis using...

OBJECTIVE Development of an artificial salivary gland will benefit patients with xerostomia after radiation therapy for upper respiratory cancer. The goal is to devise a three-dimensional (3D) culture system in which salivary cells differentiate into polarized acini that express essential biomarkers and directionally secrete alpha-amylase. Differentiated acini-like structures in a 3D biomateria...

PURPOSE/OBJECTIVES To assess the validity of filter paper (FP) against the gold standard of passive drool (PD) for collecting salivary alpha amylase as a surrogate biomarker of psychological stress in adolescents with cancer. DESIGN Part of a longitudinal, descriptive study of symptoms in adolescents with cancer during chemotherapy. SETTING A pediatric hematology/oncology treatment center. ...

Aggressive behavior in mice caused a vast release of renin into the plasma. The present data support previous findings that the main sources were the submaxillary gland and kidney. In addition, unidentified salivary glands capable of releasing renin into the saliva were demonstrated by alpha-adrenergic stimulation. The role of these glands in generating plasma renin is unknown. Experiments were...

BACKGROUND It has been previously demonstrated that patients with reflux esophagitis exhibit a significant impairment in the secretion of salivary protective components versus controls. However, the secretion of salivary protective factors in patients with nonerosive reflux disease (NERD) is not explored. The authors therefore studied the secretion of salivary volume, pH, bicarbonate, nonbicarb...
