Findings regarding the association between n-3 polyunsaturated fatty acid (PUFA) status and depression are conflicting. Thus, the authors studied associations between PUFA intake and depressive symptoms. In 1996, depressive symptoms were assessed in a subsample of participants from the Supplementation with Antioxidant Vitamins and Minerals (SU.VI.MAX) Study using the Center for Epidemiologic Studies Depression Scale (CES-D). In 2007-2009, information on CES-D score, history of depression, and use of antidepressant medication was obtained. Intakes of n-3 PUFAs were estimated from repeated 24-hour dietary records collected during 1994-1996. Subjects with depressive symptoms (cases) were identified using CES-D scores greater than 15 and/or antidepressant use. Logistic regression analyses were used. Cross-sectional (n = 2,744) and longitudinal (n = 1,235) associations between quartiles of PUFA intake and depressive symptoms were estimated. In cross-sectional analyses, quartile of n-3 PUFA intake was associated with lower odds of depressive symptoms (fourth quartile vs. first: odds ratio = 0.74, 95% confidence interval: 0.58, 0.95; P for trend = 0.001). No association between PUFA intake and incidence of depressive symptoms over 13 years was detected. This study provides new insights into the PUFA-depression link. While no association between n-3 PUFA intake and incidence of depressive symptoms was detected, an association was observed in cross-sectional analyses, which may reflect unhealthy dietary patterns among subjects with depressive symptoms. © The Author 2012.

Prenatal olfactory learning has been demonstrated in a wide variety of animals, where it affects development and behaviour. Young ants learn the chemical signature of their colony. This cue-learning process allows the formation of a template used for nest-mate recognition in order to distinguish alien individuals from nest-mates, thus ensuring that cooperation is directed towards group members and aliens are kept outside the colony. To date, no study has investigated the possible effect of cue learning during early developmental stages on adult nest-mate recognition. Here, we show that odour familiarization during preimaginal life affects recognition abilities of adult Aphaenogaster senilis ants, particularly when the familiarization process occurs during the first larval stages. Ants eclosed from larvae exposed to the odour of an adoptive colony showed reduced aggression towards familiar, adoptive individuals belonging to this colony compared with alien individuals (true unfamiliar), but they remained non-aggressive towards adult individuals of their natal colony. Moreover, we found that the chemical similarity between the colony of origin and the adoptive colony does not influence the degree of aggression, meaning that the observed effect is likely to be due only to preimaginal learning experience. These results help understanding the developmental processes underlying efficient recognition systems. Source
