WHY: Depression is common in late life, effecting nearly five million of the 31 million Americans aged 65 and older. Both major and minor depression are reported in 13% of community dwelling older adults, 24% of older medical outpatients and 43% of both acute care and nursing home dwelling older adults. Contrary to popular belief, depression is not a natural part of aging. Depression is often r...

A maternal effect is a causal influence of the maternal phenotype on the offspring phenotype over and above any direct effects of genes. There is abundant evidence that maternal effects can have a major impact on offspring fitness. Yet, no previous study has investigated the potential role of maternal effects in influencing the severity of inbreeding depression in the offspring. Inbreeding depr...

Introduction: The present study examined the relationship between personality profiles and self-defeating ideation and behaviour. The present study examines depression as a psychological condition that is related to self-defeating patterns of thought and behaviour. Method: The present study utilized data from 159 participants. A substantial portion of the sample received psychiatric care for de...

Depression is a serious mental illness. usually characterized by feelings of sadness, hopelessness, anxiety, restlessness, and even loss life. However, not everyone who experiences depression can get professional treatment. If left unchecked, it worsen the health conditions experienced person. Social media, one which increasingly popular twitter be utilized to help deal with problem undetected ...

Progress in understanding multisensory integration human have suggested researchers that the may result into enhancement or depression of incoming signals. It is evident based on different psychological and behavioral experiments stimuli coming from perceptual modalities at same time place, signal having more strength under influence emotions effects response accordingly. Current research has n...

background: depression is common in chronic medical illnesses including hf. it has been established that depression has different rates in different races and the reported depression rates among hospitalized patients range from 13% to 77%; nevertheless, there is remarkably little information on the prevalence of depression and the   impact of demographic and health status in the north of iran ....

Depression following a stroke, also referred to as post-stroke depression (PSD), has long been recognized as one of the most common complications of stroke. PSD has significant adverse consequences on the recovery of motor and cognitive deficits, as well as on the risk of mortality associated with stroke. The prevalence of PSD varies over time with an apparent peak 3-6 months after stroke and s...

In an inbred population, selection may reduce the frequency of deleterious recessive alleles through a process known as purging. Empirical studies suggest, however, that the efficacy of purging in natural populations is highly variable. This variation may be due, in part, to variation in the expression of inbreeding depression available for selection to act on. This experiment investigates the ...

Understanding how parental distance affects offspring fitness, i.e., the effects of inbreeding and outbreeding in natural populations, is a major goal in evolutionary biology. While inbreeding is often associated with fitness reduction (inbreeding depression), interpopulation outcrossing may have either positive (heterosis) or negative (outbreeding depression) effects. Within a metapopulation, ...

Mating between related individuals results in inbreeding depression, and this has been thought to select against incestuous matings. However, theory predicts that inbreeding can also be adaptive if it increases the representation of genes identical by descent in future generations. Here, I recapitulate the theory of inclusive fitness benefits of incest, and extend the existing theory by derivin...
