National Institute of Advanced Industrial Science and Technology (AIST) Prototypes System for Evaluating Mental Stress Using Salivary Samples.Tokyo, Japan, Nov 8, 2005 - (JCNN JCNN Japan Corporate News Network ) - The National Institute of Advanced Industrial Science and Technology The National Institute of Advanced Industrial Science and Technology (産業技術総合研究所 (AIST AIST Advanced Industrial Science and Technology (Japan) AIST National Institute of Advanced Industrial Science and Technology (Japan) AIST Association for Iron & Steel Technology ) announced on November 2 that the Stress Management Team of the AIST Human Stress Signal Research Center has devised an innovative system to evaluate the degree of mental stress in collaboration with SCIVAX Corporation. The new system, which consists of a lab-on-a-chip, laser-induced fluorescence detection device and analysis method based on antigen-antibody reaction and electrophoresis, can rapidly measure stress-related substances secretory immunoglobulin A secretory immunoglobulin A, n protein found in bodily secretions; can protect against antigen overload by binding the antigens and transporting them through the liver into the bile to be eliminated. In some cases it can prevent the absorption of antigens. (S-IgA) and cortisol cortisol (kôr`tĭsôl') or hydrocortisone, steroid hormone that in humans is the major circulating hormone of the cortex, or outer layer, of the adrenal gland. in salivary samples. Compared to the existing blood sample-based inspection technique, this system can reduce the stress burden in a sampling process so it can deliver more precise results. The system is also expected to be used to objectively evaluate items and products that are comfortable to use or have healing effects. Going forward, the center will proceed with further research with a view to commercializing the system. The center expects that the new system will contribute to improvement in mental health care and preventing emotional problems and suicides.
