Periodic occupational health examinations often require venepuncture. Acute psychological and physical stressors during such procedure result in sympathetic stimulation and increased salivary protein secretion, including salivary α-amylase (SAA). We studied SAA response to venepuncture during such examination. Fifty-eight healthy males undergoing periodic medical examination reported perceived ...

Most notable among the acute phase proteins is serum amyloid A (SAA), levels of which can increase 1000-fold during infections, aseptic inflammation, and/or trauma. Chronically elevated SAA levels are associated with a wide variety of pathological conditions, including obesity and rheumatic diseases. Using a recombinant hybrid of the two human SAA isoforms (SAA1 and 2) that does not exist in vi...

Background: Nasopharyngeal carcinoma (NPC) remains as a devastating malignancy due to a lack of effective therapy for recurrence and metastasis. Salvianolic acid A (SAA), a compound extracted from Salvia miltiorrhiza, possesses a variety of biological properties such as antioxidant, antithrombotic, myocardial ischemia protection and anti-hepatic-fibrosis. However, the effect of SAA on NPC cells...

A spherical antenna array (SAA) is the configuration of choice in obtaining an with isotropic characteristics. An SAA has capacity to receive electromagnetic wave (EM) equal intensity irrespective direction-of-arrival (DoA) and polarization. Therefore, DoA estimation waves impinging on unknown mutual coupling needs be considered. In domain, traditional multiple signal classification algorithm (...

Introduction: Tension-type headache is the most common type of headache across the world. Saliva as a non-invasive medium is used to detect a wide range of diseases. Salivary Alpha-Amylase (SAA) levels has been suggested as a potential indirect marker for detecting Sympathoadrenal Medullary (SAM) activity, which is activated by pain. Significant correlation was found between SAA levels and pain...

Serum amyloid A protein (SAA) is a major acute-phase protein in humans and most other mammals. In addition, it is the serum precursor of the major protein constituent of reactive amyloid fibrils. Sequence analyses have identified a number of polymorphic forms of human SAA and amyloid A protein (AA), but the question of the number of genes encoding SAA in the human has not been addressed. In add...

This study investigated the metabolism of salvianolic acid A (SAA) both in vivo and in vitro. Liquid chromatography-mass spectrometry analysis of drug-containing rat bile samples and bile samples hydrolyzed by glucuronidase revealed a series of methylated conjugates of SAA and its glucuronides, as well as the predominance of the methylation pathway of SAA in rats. For the first time, four major...

Bacterial endotoxin is a potent inducer of the serum amyloid protein (apo-SAA), a high density lipoprotein (HDL) apoprotein. In a study of the induction of apo-SAA and the structure of apo-SAA-rich lipoprotein particles in mice, we have observed that, following intraperitoneal administration of Salmonella typhosa lipopolysaccharide (50 micrograms), plasma apo-SAA levels rose from base-line leve...

The serum precursor SAA of the secondary amyloid protein AA has been detected by solid-phase radioimmunoassay as a normal serum alpha-globulin of mol wt 160,000, which dissociates to a more stable 12,500 dalton moiety on treatment with formic acid. In 12 strains of mice, including T-cell-deficient nude mice, treated with the amyloid-inducing agents lipopolysaccharide (LPS) or casein, SAA behave...
