Synaptic loss in schizophrenia: a meta-analysis and systematic review of synaptic protein and mRNA measures.
TL;DR: Findings of moderate–large reductions in synaptophysin in hippocampus and frontal cortical regions, and a tendency for reductions in other pre- and postsynaptic proteins in the hippocampus are consistent with models that implicate synaptic loss in schizophrenia, but they also identify potential differences between regions and proteins, suggesting synaptic loss is not uniform in nature or extent.

TL;DR: A comprehensive review of the current emerging literature on trauma and adverse life events in the CHR population is provided, addressing etiological questions that cannot be answered in studies of fully psychotic or non-clinical populations.

Vernon,Oliver D. Howes +21 more
TL;DR: It is shown for the first time in vivo that levels of the synaptic marker protein SV2A are reduced in schizophrenia and unaffected by antipsychotic treatment in a rat model, indicating that there are lower synaptic terminal protein levels in schizophrenia in vivo and that antipsychotics exposure is unlikely to account for them.

Electrochemical detection of dopamine using periodic cylindrical gold nanoelectrode arrays
Da-Seul Kim,Ee-Seul Kang,Seungho Baek,Sung-Sik Choo,Yong-Ho Chung,Donghyun Lee,Junhong Min,Tae-Hyung Kim +7 more
TL;DR: The developed dopamine sensing platform CAuNE can be used for many applications including early diagnosis of neurological diseases; function tests of dopaminergic neurons derived from various stem cell sources; and toxicity assessments of drugs, chemicals, and nanomaterials on human neuronal cells.
Journal ArticleDOI
Dopamine and Noradrenaline in the Brain; Overlapping or Dissociate Functions?
TL;DR: It is suggested that DA and NA may function in parallel to facilitate learning and maintain the states required for normal cognitive processes.

TL;DR: Associations at DRD2 and several genes involved in glutamatergic neurotransmission highlight molecules of known and potential therapeutic relevance to schizophrenia, and are consistent with leading pathophysiological hypotheses.

KEGG as a reference resource for gene and protein annotation
TL;DR: The KEGG GENES database now includes viruses, plasmids, and the addendum category for functionally characterized proteins that are not represented in complete genomes, and new automatic annotation servers, BlastKOalA and GhostKOALA, are made available utilizing the non-redundant pangenome data set generated from theGENES database.

Clozapine for the treatment-resistant schizophrenic. A double-blind comparison with chlorpromazine
TL;DR: In this relatively brief study, the apparently increased comparative risk of agranulocytosis requires that the use of clozapine be limited to selected treatment-resistant patients.
