RATIONALE It has been suggested that the antipsychotic effect of antipsychotics is mediated by the antagonism of the dopamine D2 receptor in the limbic-cortical regions. Risperidone has an atypical property, but its effect on limbic-cortical regions has not been evaluated. OBJECTIVES In this study, we examined the relationship among doses of risperidone(More)
BACKGROUND Neuroimaging studies have suggested the possible role of the cerebellum in the pathophysiology of schizophrenia. However, no study has investigated the detailed structures of the cerebellum in patients without a history of neuroleptic medication. The objective of this study is to examine the volume of detailed structures of the cerebellum in(More)
Maintenance of self-renewal and pluripotency in mouse embryonic stem cells (mESCs) is regulated by the balance between several extrinsic signaling pathways. Recently, we demonstrated that heparan sulfate (HS) chains play important roles in the maintenance and differentiation of mESCs by regulating extrinsic signaling. Sulfated HS structures are modified by(More)
Recently, we have identified two 3'-phosphoadenosine 5'-phosphosulfate (PAPS) transporters (PAPST1 and PAPST2), which contribute to PAPS transport into the Golgi, in both human and Drosophila. Mutation and RNA interference (RNAi) of the Drosophila PAPST have shown the importance of PAPST-dependent sulfation of carbohydrates and proteins during development.(More)
Walker-Warburg syndrome, a progressive muscular dystrophy, is a severe disease with various kinds of symptoms such as muscle weakness and occasional seizures. The genes of protein O-mannosyltransferases 1 and 2 (POMT1 and POMT2), fukutin, and fukutin-related protein are responsible for this syndrome. In our previous study, we cloned Drosophila orthologs of(More)
T antigen (Galbeta1-3GalNAcalpha1-Ser/Thr), the well-known tumor-associated antigen, is a core 1 mucin-type O-glycan structure that is synthesized by core 1 beta1,3-galactosyltransferase (C1beta3GalT), which transfers Gal from UDP-Gal to Tn antigen (GalNAcalpha1-Ser/Thr). Three putative C1beta3GalTs have been identified in Drosophila. However, although all(More)
MOTIVATION It is well known influenza viruses recognize and bind terminal sialic acid (SA) on glycans that are found on the cell surface. In this work, we used a data mining technique to analyze the glycan array data of influenza viruses to find novel glycan structures other than SA that may be involved in viral infection. RESULTS In addition to SA(More)

It is a routine procedure for anesthesiologists to use local anesthesia (LA) before spinal needle insertion (SNI), but LA itself produces pain on injection. We evaluated the necessity of LA before spinal block using a 25-gauge needle by questioning whether LA makes SNI painless and easy. Sixty patients without lumbar abnormality for spinal block were(More)
The dopamine (DA) and serotonin (5-HT) neurotransmission systems are of fundamental importance for normal brain function and serve as targets for treatment of major neuropsychiatric disorders. Despite central interest for these neurotransmission systems in psychiatry research, little is known about the regulation of receptor and transporter density levels.(More)
