Recent progress in the genetic analysis of inbreeding depression in plants is reviewed. While the debate over the importance of genes of dominance versus overdominance effect continues, the scope of inferences has widened and now includes such facets as the interactions between genes, the relative abundance of major versus minor genes, life cycle stage expression, and mutation rates. The types ...

Inbreeding depression is assumed to be a central factor contributing to the stability of plant mating systems. Predicting the fitness consequence of inbreeding in natural populations is complicated, however, because it may be affected by the mating histories of populations generating variation in the amount of purging of deleterious alleles. Furthermore, the level of inbreeding depression may d...

BACKGROUND Exposure to traumatic events is a nonspecific risk factor for psychiatric symptoms including depression. The trauma-depression link finds support in numerous studies; however, explanatory mechanisms linking past trauma to current depressive symptoms are poorly understood. This study examines the role that attachment insecurity plays in mediating the relationship between prior exposur...

Depression is a common and disabling mental disorder that affects people of all ages, cultures and ethnic backgrounds (Henderson et al., 2000; Mathers et al., 2001; Kessler et al., 2005; Prince et al., 2007). Its presence has been recorded throughout history (Berrios, 1985), which suggests that the signs and symptoms of depression are not simply a product of our time. However, given the overwhe...

<p><span>Depression is an acute problem throughout the world. Due to worst and prolong depression many people dies in every year. The that most of are not concern fact they suffering from depression. In this research, our aim was find out whether individual depressed or by analyzing social media status. Therefore, we focused on real data. Our dataset consists 2000 sentences, which c...

In this study, we explored ways to account more accurately for responses of neurons in primary auditory cortex (A1) to natural sounds. The auditory cortex has evolved to extract behaviorally relevant information from complex natural sounds, but most of our understanding of its function is derived from experiments using simple synthetic stimuli. Previous neurophysiological studies have found tha...
