Persistent offenders and adolescence-limited offenders: Differences in life-courses.
2020
Background and Aims As our previous study indicated, almost half of juvenile delinquents continued offending in adulthood, while the rest ceased to do so. We compared these groups with each other and with non‐offenders in the life‐course use of alcohol, identity development and life situation. Methods Based on the Jyväskylä Longitudinal Study of Personality and Social Development, four groups were formed at age 42 for men and women: persistent, adolescence‐limited and adult‐onset offenders and non‐offenders. Longitudinal data (N = 369; 53% males) have been collected at ages 8, 14, 20, 27, 36, 42 and 50. Results Persistent offending, but not adolescence‐limited offending, was associated with…
Interleukin-1 inhibits drinking behaviour through prostaglandins, but not by nitric oxide formation
1997
Interleukin-1 beta (IL-1 beta) causes inhibition of drinking behaviour. Moreover it induces formation of prostaglandins (PGs) and nitric oxide (NO). Both PGs and NO are able to inhibit drinking stimulated by water deprivation or by intracerebroventricular (i.c.v.) administration of angiotensin II. In this study, we studied in the preoptic area (POA) the possible role of PGs and NO in the antidipsogenic action induced by IL-1 beta. IL-1 beta was injected in the lateral cerebral ventricle (i.c.v.) (2.5, 10, 20, and 40 ng/rat) or into POA (0.625, 1.25, 2.5, and 10 ng/rat). L-arginine (12.5, 25, 50, and 100 ng/rat), the precursor of NO, or NG-nitro-L-arginine methyl ester (L-NAME) (25, 50, and …
Vulnerability to alcohol operant-drinking behaviour: implications of environmental stim
2013
Environmental stimuli, occurring early in life, shape the drinking trajectories and the psychopathological outcome of alcohol consumption in adult life. In particular, early perinatal procedures can permanently alter various patterns of drug use and behaviour in rat adulthood (Pryce CR, 2001). Early handling (EH) apparently is responsible for neurochemical and behavioural changes in adulthood, due to boosts in maternal care after daily reunion. It has been suggested that fostered maternal care, in the form of licking and grooming, is a key feature in determining neural changes and offspring fear responses and alter the reward/reinforcement pathway through epigenetic mechanisms that likely u…
Impact of a single, intense prenatal stress on ethanol drinking behaviour and cognition in adult male rats
2015
Early exposure to stressful stimuli is crucial for developing varied behavioural patterns in adulthood such as anxiety, cognitive dysfunction and abuse disorders. The alteration of the hypothalamic–pituitary–adrenal (HPA) axis represents the neurobiological substrate responsible of the behavioural consequences of prenatal stress (PS). Indeed, prenatal manipulation of the HPA axis impacts on cognitive performance of the adult offspring, but also on vulnerability to alcohol consumption. Prenatal acute, moderate restraint stress has proved to facilitate HPA axis development of the offspring, since maternal corticosterone secretion leads to the reduction of anxiogenic behaviour and an improveme…
