background: diabetes mellitus has a strong association with the presence of depression. psychiatric morbidity and especially depression are believed to be important aspects of diabetes influencing upon treatment course and prognosis. to determine the prevalence of depression in adult diabetic populations and compare nondiabetic population, we performed the current study. methods : three hundred...

objectives: the aim of the current study was to determine the depression status of the elderly and it's related factors. methods & materials: this was a cross sectional study. sample unit was based on the elderly of isfahan city in 2007. 248 elderly aged 60 and older (125 men and 123 women) were selected randomly according to clusters related to the families that are under coverage of isfa...

abstract background: risk for anxiety and depression is increased in women with high‑risk pregnancy. the aim of this study was to evaluate anxiety and depression in women with mild and severe preeclampsia at admission and 6 weeks postpartum. materials and methods: in this cohort study, 122 preeclamptic women who were admitted to the public hospital and tamin ejtemaee hospital of mashhad were in...

The rate of adaptation to a competitive laboratory environment and the associated inbreeding depression in measures of reproductive fitness have been observed in populations of Drosophila melanogaster with mean effective breeding size of the order of 50 individuals. Two large wild-derived populations and a long-established laboratory cage population were used as base stocks, from which subpopul...

Selection by inbreeding depression should favour mating biases that reduce the risk of fertilization by related mates. However, equivocal evidence for inbreeding avoidance questions the strength of inbreeding depression as a selective force in the evolution of mating biases. Lack of inbreeding avoidance can be because of low risk of inbreeding, variation in tolerance to inbreeding or high costs...

1 Background and Aims Reduction in offspring fitness resulting from mating between 2 neighbors is interpreted as biparental inbreeding depression. However, little is known 3 about the relationship between the genetic relatedness of parents and the biparental 4 inbreeding depression in their progeny in natural populations. Here, the effect of kinship 5 between mates on the fitness of their proge...

Little is known about how inbreeding alters selection on ecologically relevant traits. Inbreeding could affect selection by changing the distribution of traits and/or fitness, or by changing the causal effect of traits on fitness. Here, I test whether selection on egg size varies with the degree of inbreeding in the seed-feeding beetle, Stator limbatus. There was strong directional selection fa...

Offspring of depressed parents are at risk for depression and recent evidence suggests that reduced positive affect (PA) may be a marker of risk. We investigated whether self-reports of PA and fMRI-measured striatal response to reward, a neural correlate of PA, are reduced in adolescent youth at high familial risk for depression (HR) relative to youth at low familial risk for depression (LR). F...
