in this paper we study the existence of commuting regular elements, verifying the notion left (right) commuting regular elements and its properties in the groupoid g(n) . also we show that g(n) contains commuting regular subsemigroup and give a necessary and sucient condition for the groupoid g(n) to be commuting regular.

Precerebellin (Cbln)-related peptides are known to modulate the secretory activity and growth of the adrenal gland. However, precise expression of the Cbln-related genes and Cbln1 peptide in the adrenal remains unclear. Therefore, we investigated, using RT-PCR, QPCR, Western blotting, immunohistochemistry and hormonal assays, their expression in the adrenals of adult rats and in the course of p...
