Subcortical structures, which include the basal ganglia and parts of limbic system, have key roles in learning, motor control emotion, but also contribute to higher-order executive functions. Prior studies reported volumetric alterations subcortical regions schizophrenia. Reported results sometimes been heterogeneous, few large-scale investigations conducted. Moreover, assessed asymmetries volumes Here, as a work completely independent study performed by ENIGMA consortium, we conducted...

Compelling evidence in Caucasian populations suggests a role for copy-number variations (CNVs) autism spectrum disorder (ASD) and schizophrenia (SCZ). We analyzed 1,108 ASD cases, 2,458 SCZ 2,095 controls Japanese population confirmed an increased burden of rare exonic CNVs both disorders. Clinically significant (or pathogenic) CNVs, including those at 29 loci common to disorders, were found about 8% which was significantly higher than controls. Phenotypic analysis revealed association...

Aim Studies have reported that cognitive decline occurs after the onset of schizophrenia despite heterogeneity in function among patients. The aim this study was to investigate degree estimated patients with by comparing premorbid intellectual functioning and current functioning. Methods A total 446 (228 male, 218 female), consisting three sample sets obtained from 11 psychiatric facilities, 686 healthy controls participated study. Wechsler Adult Intelligence Scale‐ III ( WAIS‐III ) used...

Abstract Differential diagnosis is sometimes difficult in practical psychiatric settings, terms of using the current diagnostic system based on presenting symptoms and signs. The creation a novel objective biomarkers expected to take place. Neuroimaging studies others reported that subcortical brain structures are hubs for various psycho-behavioral functions, while there so far no neuroimaging data-driven clinical criteria overcoming limitations system, which would reflect cognitive/social...

Abstract According to the operational diagnostic criteria, psychiatric disorders such as schizophrenia (SZ), bipolar disorder (BD), major depressive (MDD), and autism spectrum (ASD) are classified based on symptoms. While its cluster of symptoms defines each these disorders, there is also an overlap in between disorders. We hypothesized that similarities differences cortical structural neuroimaging features among T1-weighted magnetic resonance imaging scans were performed for 5,549 subjects...

Volatile aldehydes are formed during storage of bottled beer on the shelf and give an off-flavour. Results showed that these by oxidation higher alcohols in with melanoidins. On alcohols, hydrogen or electron is probably transferred from to reactive carbonyl groups melanoidins lower molecular weights. The amino-carbonyl reaction boiling wort. Molecular oxygen does not oxidize absence melanoidins, but accelerates their proceeds more rapidly at high temperature low pH value.

"Foaming proteins" that retained the full foaming capacity of original beer were isolated by ultrafiltration followed ammonium sulfate precipitation and ion-exchange chromatography on diethylaminoethylcellulose. Because content proteins correlated well with head formation many samples beer, these seem to be responsible for foaming. Foaming consisted three fractions molecular weights 90,000–1,000,000, 40,000, 15,000. These all surface-active but differed in mechanism their contribution The...

Aim: Suicide is associated not only with primary psychiatric disorders but also physical disorders. Physicians' education on suicide prevention contributes to reducing suicide. Therefore, medical residents, who contact patients daily and eventually become physicians in each specialty, might be the most appropriate candidates for intervention. In this article, we introduce our newly developed intervention program among residents. Methods: We a 2‐hour based Mental Health First Aid (MHFA),...
