    Notes: Abstract. The immunohistochemical study revealed tyrosine hydroxylase (TH), dopamine β-hydroxylase (DBH), phenylethanolamine N-methyltransferase (PNMT), serotonin, glutamate decarboxylase (GAD) and γ-aminobutyric acid (GABA) immunoreactivities in the mouse carotid body. TH and DBH immunoreactivities were found in almost all chief cells and a few ganglion cells, and in relatively numerous varicose nerve fibers of the carotid body. The histofluorescence microscopy showed catecholamine fluorescence in almost all chief cells. However, no PNMT immunoreactivity was observed in the carotid body. Serotonin, GAD and GABA immunoreactivities were also seen in almost all chief cells of the carotid body. From combined immunohistochemistry and fluorescence histochemistry, catecholamine and serotonin or catecholamine and GABA were colocalized in almost all chief cells. Thus, these findings suggest that noradrenaline, serotonin and GABA may be synthesized and co-exist in almost all chief cells of the mouse carotid body and may play roles in chemoreceptive functions.

    Notes: Abstract We develop an abstract computational model, the abstract rewriting system on multisets, called ARMS, to deal with systems with a large number of degree of freedom, like liquids, and to confirm that they can simulate the emergence of the complex behavior of cycles, such as autocatalytic cycles, with their period-doubling and fusion of cycles, which are often found in the emergence of life. Furthermore, we clarify the conditions in which ARMS generates cycles through the theoretical investigation of ARMS.
