OBJECTIVES To investigate socioeconomic inequalities in outcome of pregnancy and neonatal mortality associated with congenital anomalies. DESIGN Retrospective population based registry study. SETTING East Midlands and South Yorkshire regions of England (representing about 10% of births in England and Wales). PARTICIPANTS All registered cases of nine selected congenital anomalies with poor...

Existing data suggest a negative correlation between maternal sleep deprivation and male offspring reproductive capability. However, there is dearth of information on the critical period of development during which reproductive organs may be programmed. Thirty pregnant rats were divided into six groups based on the Gestation Days (GD) during which they were sleep deprived as follows: GD 17 cont...

This paper reviews evidence from both human and non-human primate studies concerning the role of early adverse experiences in the onset and course of adult depressive disorders. Despite accumulating evidence that stressful life events can play a major role in precipitating the onset of depressive episodes in humans, the mechanisms by which early experiences mediate and moderate the risk for lat...

BACKGROUND The epidemiological evidence linking socioeconomic deprivation with adverse pregnancy outcomes has been conflicting mainly due to poor measurement of socioeconomic status (SES). Studies have also failed to evaluate the plausible pathways through which socioeconomic disadvantage impacts on pregnancy outcomes. We investigated the importance of maternal SES as determinant of birth weigh...

BACKGROUND Intrauterine growth restriction (IUGR) results from a lack of nutrients transferred to the developing fetus, particularly oxygen and glucose. Increased expression of the cytoprotective mitochondrial peptide, humanin (HN), and the glucose transporter 8, GLUT8, has been reported under conditions of hypoxic stress. However, the presence and cellular localization of HN and GLUT8 in IUGR-...

We hypothesize that rapid eye movement or REM sleep evolved, in part, to mediate sexual/reproductive behaviors and strategies. Because development of sexual and mating strategies depends crucially on early attachment experiences, we further hypothesize that REM functions to mediate attachment processes early in life. Evidence for these hypotheses comes from (1) the correlation of REM variables ...

The long-term effects of early adverse experiences on later psychosocial functioning are well described in humans, but sparsely documented for chimpanzees. In our earlier studies, we investigated the effects of maternal and social deprivation on three groups of ex-laboratory chimpanzees who experienced either an early or later onset of long-term deprivation. Here we expand our research by addin...

OBJECTIVE Early life events often lead to deficits in CNS serotonin function, which underlie a number of reoccurring psychopathological disorders. Studies using rhesus macaques have demonstrated that early maternal deprivation reduces CNS serotonin turnover, as measured by cisternal CSF 5-HIAA concentrations. In addition, individual differences in CSF 5-HIAA remain stable from the first year of...

Depression is a common mental disorder; however, its molecular mechanism has not been fully elucidated. In this study, we investigated the role of maternal deprivation (MD) and chronic mild stress (CMS) in the pathogenesis of depression in rat models. The mRNA levels of prostate apoptosis response-4 (Par-4) and dopamine receptor D2 (DRD2) genes in the striatum were measured by real-time PCR. Me...

Dietary restriction appears to act as a general non-genetic mechanism that can robustly prolong lifespan. There have however been reports in many systems of cases where restricted food intake either shortens, or does not affect, lifespan. Here we analyze lifespan and the effect of food restriction via deprived peptone levels on lifespan in wild isolates and introgression lines (ILs) of the nema...
