Parental autonomy granting during adolescence: exploring gender differences in context.
This study investigated the ways in which 2 indicators of parental autonomy granting, adolescents' decision-making input and parental knowledge of adolescents' daily experiences, differed as a function of contextual factors (i.e., parents' gender role attitudes or sibling dyad sex composition) and boys' and girls' personal qualities (i.e., gender, pubertal status, developmental status, or birth order) in a sample of 194 families with firstborn (M = 15.0 years) and second-born (M = 12.5 years) adolescents. Firstborns were granted more autonomy than second borns, especially in families with firstborn girls and second-born boys. Girls in families marked by traditional maternal gender role attitudes were granted fewer autonomy opportunities. Postmenarcheal second-born girls were granted more opportunities for autonomy than were premenarcheal second-born girls, but only in families with less traditional maternal gender role attitudes.

Linking parents' work pressure and adolescents' well-being: insights into dynamics in dual-earner families.
This study focused on the connections between mothers' and fathers' work pressure and the psychological adjustment of their older (M = 15 years) and younger (M = 12.5 years) adolescent offspring in a sample of 190 dual-earner families. Structural equation models revealed that the effects of work pressure on adolescent well-being were mediated by parental role overload and parent-adolescent conflict. Work-family linkages were similar for mothers and fathers with one exception: Fathers' work pressure predicted both parents' feelings of role overload, whereas mothers' work pressure predicted only their own overload, not their spouses'. The patterns of association were consistent for older and younger adolescent siblings.

Renin-angiotensin mediation of adrenal catecholamine secretion induced by hypoglycaemia in the cat.
1 The mechanism involved in catecholamine (CA) release from the cat adrenal gland in response to insulin hypoglycaemia was studied. In intact cats, hypoglycaemia induced an 11 fold increase in adrenomedullary CA secretion. 2 Acute bilateral nephrectomy nearly abolished the increased CA release from the adrenal gland during hypoglycaemia. 3 Infusion of Sar1-Ileu8-Angiotensin II (AII), a competitive AII antagonist, suppressed the adrenomedullary response to the insulin-induced hypoglycaemia. After termination of the antagonist infusion CA secretion from the adrenal medulla increased rapidly, reaching the same level as in insulin-treated cats. 4 Infusion of rabbit anti-angiotensin I antibodies suppressed CA release from the adrenal gland of hypoglycaemic cats. This effect was more prolonged than that of Sar1-Ileu8-AII. 5 These results indicate that CA release from the adrenal medulla of the cat in response to insulin-induced hypoglycaemia, is mediated through the renal reninangiotensin system. Since hypoglycaemia causes sympathetic stimulation through a central mechanism, angiotensin may act through the central nervous system.

Angiotensin II mediation of adrenal catecholamine secretion induced by intrarenal isoprenaline infusion.
Isoprenaline infusion into the renal artery of the cat induced an increase in the catecholamine (CA) secretion rate from the adrenal gland. CA release by isoprenaline was preferentially noradrenaline. Intravenous infusion of an angiotensin II (A II) antagonist abolished adrenal CA response to intrarenal isoprenaline injection. It is suggested that intrarenal isoprenaline infusion stimulates renal renin release and A II production which, in turn, stimulates adrenal CA secretion.
