conclusions religiosity has been used as a coping mechanism among blacks. religiosity may also be related to stress regulation among black youth. future studies need to test complex associations between race, sex, religiosity, chronic stress, coping, and function of hypothalamo-pituitary-adrenal (hpa). it is not known whether male black youth who are and those who are not religious differently ...

background although the link between psychological distress and altered cortisol level has been already shown; very limited information exists about this association among black youth. objectives we tested sex differences in predictive role of symptoms of anxiety during adolescence on annual decline in morning salivary cortisol levels in early adulthood among black youth. conclusions our findin...

The objective was to test the hypothesis that dopamine regulates prolactin (PRL) secretion by determining acute changes in catecholamine concentrations in hypophyseal portal blood of cattle and their relation to peripheral blood concentration of PRL in hypophyseal stalk-transected (HST) and sham-operated control (SOC). Holstein heifers were subjected to neurosurgery to collect hypophyseal porta...

In virgin mice of strain A, anterior hypophyseal transplants increased the incidence of mammary cancers; in castrate males bearing hypophyseal and ovarian grafts, the number of mammary can eers exceeded that noted after transplantation of ovaries alone. These findings were interpreted as owing to the release of gonadotrophins by the hy pophyseal transplants, which stimulate the output of estrog...

• Relationships between cardiac and hypophyseal functions have been recognized since early clinical observations of cardiac enlargement and failure in acromegaly. Experimental attention has been directed at hypophyseal influences on cardiac size," cardiac output,' and the ability of the heart to hypertrophy." The relationship of cardiac changes to peripheral circulatory events following hypophy...

until 2000 it was believed that gonadotropin-releasing hormone (gnrh) was the sole regulator of hypophyseal gonadotropes. in 2000, the discovery of a gonadotropin inhibitory hormone (gnih) initiated a revolution in the field of reproductive physiology. identification of gnih homologues in mammals, the arginine-phenylalanine- amide (rfamide)-related peptides (rfrps), indicated a similar function...
