Decreased GyBAA Receptor Function in the Brain Stem during Pancreatic Regeneration in Rats

Gamma amino outyric acid is a major inhibitory neurotrarsr titter in the central nervous system. In the preset study sv, Have investigate(' the alteration of GABA receptor, In t he hrain stem of rats during pancreatic regeneration. Three groups of rats were used for the study: sham operated, 72 It and 7 days partially pancreatectonnsea. GABA was (juan- (ified by [H]GABA receptor iispiacement method. GABA receptor kin: 10, pat at i et•ers were studied by using the binding of F'.](iAhA as ligand to the Triton X-100 treated me,i1,;-:mes a1,J displacement with unlabelled GABA. GhRA,v receptor activity was studied by using the [` -1 h3cuculline and displacement with unlabellecV euculline. ;.\13A content significantly decreased (1' < (1.(101 ) it, 0-e brain stern during the regeneration of pancreas.

Effect of Gender-role Orientations and Communication Styles on Executive Performance

Biosocial profile can produce variations in Gender-role Orientation of executives. Biosocial variables are not responsible for the development of Communication Style except in cases of number of children, dual career family and fathers occupation. Gender-role orientation is a function of Communication Style. Executive performance is a function of Communication Style.Gender- role orientation can have a decisive influence on executive performance. The cumulative effect of Communication Style and gender role orientation can produce variations in executive performance. Open Communication Style is predominantly responsible for the creation of a higher level executive performance than other Communication Styles.
