Among mammals, genetic recombination occurs at highly delimited sites known as recombination hotspots. They are typically 1-2 kb long and vary as much as a 1,000-fold or more in recombination activity. Although much is known about the molecular details of the recombination process itself, the factors determining the location and relative activity of(More)
OBJECTIVES The apolipoproteinE epsilon4 (APOE epsilon4) allele and a history of depression are each separate risk factors for cognitive decline (CD). However, little research has investigated whether a history of depression influences the relationship between APOE epsilon4 and CD. The present study examined whether depressive symptoms had greater influence(More)
OBJECTIVE The aim of this study was to develop and test a model of depression, hippocampal changes, and cognitive decline. METHOD Participants were 248 community-dwelling, depressed patients and 147 healthy, non-depressed individuals 60 years and older. Participants received a structured interview assessing current depressive symptoms and past depressive(More)
OBJECTIVES Studies suggest early-onset depression (EOD) is associated with a more severe course of the depressive disorder, while late-onset depression (LOD) is associated with more cognitive and neuroimaging changes. This study examined if older adults with EOD, compared with those with LOD, would exhibit more severe symptoms of depression and, consistent(More)
OBJECTIVE the apolipoprotein E epsilon-4 (APOE [small element of] 4) allele and depression are independently associated with increased risk for cognitive decline (CD). The authors have reported that depressed elders with an APOE [small element of]4 allele had greater CD compared with depressed elders without the allele. Depression affects the hippocampus,(More)
OBJECTIVE Financial incentives may have utility in promoting psychotherapy attendance and adherence, leading to improved clinical functioning. This study presents results from a novel application of financial incentives-a progressively lowered pay scale that rewards therapy attendance and adherence. METHOD Overall, 110 outpatients participated; 56(More)
OBJECTIVES The atypical depression (AD) subtype has rarely been examined in older patients. However, younger AD patients have been characterized as having more severe and chronic symptoms of depression compared with non-AD patients. DESIGN Secondary data analysis by using analyses of variance and Growth Curve Modeling. SETTING Clinical Research Center(More)
