Background Following the Great East Japan Earthquake on March 11, 2011, nuclear disaster at Fukushima Daiichi Nuclear Power Plant has continued to affect mental health status of residents in evacuation zone. To examine evacuee after accident, we conducted Mental Health and Lifestyle Survey as part ongoing Management Survey. Methods We measured using Kessler 6-item psychological distress scale (K6) a total 73,569 (response rate: 40.7%) evacuees aged 15 over who lived zone Prefecture. then...

Betaine is known to act against various biological stresses and its levels were reported be decreased in schizophrenia patients. We aimed test the role of betaine pathophysiology, evaluate potential as a novel psychotherapeutic.Using Chdh (a gene for synthesis)-deficient mice betaine-supplemented inbred mice, we assessed psychiatric psychotherapeutic, by leveraging metabolomics, behavioral-, transcriptomics DNA methylation analyses.The Chdh-deficient revealed remnants behaviors along with...

Schizophrenia is one of the major psychiatric disorders, and lipids have focused on important roles in this disorder. In fact, related to various functions brain. Previous studies indicated that phospholipids, particularly ones containing polyunsaturated fatty acyl residues, are deficient postmortem brains from patients with schizophrenia. However, due difficulties handling human brains, large size complex structures brain, there little agreement regarding qualitative quantitative...

Objective: CHRNA7, coding α-7 nicotinic acetylcholine receptor (α7 nAChR), is involved in cognition through interneuron modulation of dopamine and glutamate signaling. CHRNA7 its partially duplicated chimeric gene CHRFAM7A have been implicated schizophrenia linkage association studies. Method: Expression mRNA was measured the postmortem prefrontal cortex more than 700 subjects, including patients with schizophrenia, bipolar disorder, major depression, normal comparison subjects. The effects...

Cytogenomic mutations and chromosomal abnormality are implicated in the neuropathology of several brain diseases. Cell heterogeneity tissues makes their detection validation difficult, however. In present study, we analyzed gene dosage alterations DNA schizophrenia patients compared those with copy number variations (CNVs) identified as well Asian lymphocyte attempted to obtain hints at pathological contribution cytogenomic instability schizophrenia. Brain was extracted from postmortem...

In schizophrenia (SCZ), neurons in the brain tend to undergo gross morphological changes, but related molecular mechanism remains largely elusive. Using Kif3b+/- mice as a model with SCZ-like behaviors, we found that high-betaine diet can significantly alleviate schizophrenic traits neuronal morphogenesis and behaviors. According deficiency transport of collapsin response mediator protein 2 (CRMP2) by KIF3 motor, identified significant reduction lamellipodial dynamics developing cause...

Abstract Aim The etiology of bipolar disorder (BD) remains unknown; however, lipid abnormalities in BD have received increasing attention recent years. In this study, we examined the expression levels enzyme proteins associated with metabolic pathway phosphoinositides (PIs) and their downstream effectors, protein kinase B (Akt1) glycogen synthase 3β (GSK3β), which been assumed to be targets mood stabilizers such as lithium, postmortem brains patients BD.

Abstract The etiology of schizophrenia includes phospholipid abnormalities. Phospholipids are bioactive substances essential for brain function. To analyze differences in the quantity and types phospholipids present tissue patients with schizophrenia, we performed a global analysis multiple samples using liquid chromatography electrospray ionization mass/mass spectrometry (LC-ESI/MS/MS) imaging mass (IMS). We found significantly decreased 16:0/20:4-phosphatidylinositol (PI) levels prefrontal...
