Indigenous microbiota have several beneficial effects on host physiological functions; however, little is known about whether or not postnatal microbial colonization can affect the development of brain plasticity and a subsequent physiological system response. To test the idea that such microbes may affect the development of neural systems that govern the(More)
Serotonin (5-HT) is considered to play a significant role in anxiety-related behaviors in animals through actions on the amygdaloid complex. To evaluate this role from the point of neurotransmitter release regulation, nystatin-perforated patch recording was employed on mechanically dissociated basolateral amygdala neurons containing functional synaptic(More)
BACKGROUND The construct validity of alexithymia and its assessment using the 20-item Toronto Alexithymia Scale (TAS-20) in Japan is unknown. Low reliability has been found for the third factor of the TAS-20 in some cultures, and the factor structure for psychosomatic disorder patients has not been adequately investigated. Although alexithymia most likely(More)
Daily restraint for 3 weeks was shown to atrophy dendrites of hippocampal pyramidal neurons in rats. Brain-derived neurotrophic factor (BDNF), which maintains neuronal survival and morphology, has been shown to decrease in response to acute stress. Plasma glucocorticoid (GC) and serotonergic projections from the raphe nuclei play major roles in reducing(More)
The expression of ERs alpha and beta and serotonergic neurons were evaluated in the brains of mice prenatally exposed to Bisphenol A, a known endocrine disrupting chemical (EDc). Bisphenol A was administered orally at a dose of 2ng/g body weight on gestinational days 11-17 to pregnant ICR mice. Newborn male offspring (Bis-A mice) were evaluated for the(More)
Although anecdotal comments on detrimental effects of psychosocial stress on liver diseases can be found even in the early literature, only recently has scientific evidence been reported. The present article reviewed such evidence to demonstrate how stress exacerbates liver diseases. A search of the literature from the last two decades was performed using(More)
Some previous works have further expanded the 'Brain-Gut axis', that is a bi-directional interaction between the gut and brain function, into a relationship of the brain with the liver. However, all the details of such brain-liver relationship were not fully understood because appropriate animal models had not been established yet. Here we developed a novel(More)
BACKGROUND Psychological interventions may be valuable in atopic dermatitis. We systematically reviewed and carried out a meta-analysis of randomized controlled trials of psychological interventions. METHODS Electronic searches and manual journal searches were carried out. Two coders independently coded study designs, participants, treatments and outcome(More)
The relationship between exposure to endocrine-disrupting chemicals (EDs) and risk to reproductive organs is well documented, but the influence of EDs on behavioral development has not been studied. In this study we evaluated the effect of fetal exposure to bisphenol A, which mimics estrogenic activity, on aggressive behavior and hormonal change in male(More)
IL-15 is thought to be involved in the pathogenesis of rheumatoid arthritis (RA). We found that IL-15 plays an important role in the development of murine collagen-induced arthritis (CIA). The incidence and severity of CIA were slightly decreased in IL-15 KO mice but were increased in IL-15 Tg mice compared with wild-type (WT) mice. The levels of type II(More)
