Introduction: The prenatal stress is a key factor which affects the growth and function of the brain. Several studies have shown that prenatal stress induces deficits in learning and memory of the offspring. The prenatal stress alters the activity of neurotransmitters, such as noradrenaline, dopamine and serotonin, via over-activation of the hypothalamic–pituitary–adrenal axis. In addition, the...

Prenatal stress is reported to increase the risk of nervous, endocrine and metabolism diseases, immune dysfunction. The influence of prenatal stress on immune system is complicated, which include the changes of immune cells, cytokines, immune organs, hematopoietic stem cells. The mechanism accepted is that prenatal stress cause secretion changes of stress hormones like adrenaline and glucocorti...

Chronic psychological stress is a risk factor for osteoporosis. Maternal active mastication during prenatal stress attenuates stress response. The aim of this study is to test the hypothesis that maternal active mastication influences the effect of prenatal stress on bone mass and bone microstructure in adult offspring.

Exposure to prenatal and early-life stress results in alterations in neural connectivity and an increased risk for neuropsychiatric disorders. In particular, alterations in amygdala connectivity have emerged as a common effect across several recent studies. However, the impact of prenatal stress exposure on the functional organization of the amygdala has yet to be explored in the prematurely-bo...

Prenatal stress can cause long-term effects on cognitive functions in offspring. Hippocampal synaptic plasticity, believed to be the mechanism underlying certain types of learning and memory, and known to be sensitive to behavioral stress, can be changed by prenatal stress. Whether enriched environment treatment (EE) in early postnatal periods can cause a recovery from these deficits is unknown...
