    Notes: This study investigated the effects of head posture on mandibular habitual closing movement. Ten healthy subjects were examined. Head posture was evaluated as a sagittally viewed inclination of the head, and was changed from 25° forward bending up to 30° backward bending in 5° increments. The mandibular opening and closing movement was measured at each head posture. As the head bended forward, the closing path approached the maximum intercuspal position from the anterior region, and as the head was bent backward, the closing path approached the maximum intercuspal position from the posterior region. However, the limit of this relationship was found when the head was bent forward to some extent. There was also a correlation between the head posture and the stability of the closing movement. The forward bending of the head decreased the stability of the closing path, and conversely, the backward bending increased the stability of the closing path. It was concluded that the head posture affects the direction and stability of the mandibular closing movement. Possible underlying reasons for these findings are masticatory muscle activity and the tension and resistance of inframandibular soft tissue varying with the change of head posture.

    Notes: Summary The presence of an enzyme activity which hydrolyzes glycyl-d-aspartate was found in the homogenates of pig kidney cortex. The activity was inhibited by metal chelating agents and cilastatin, suggesting that the enzyme was a cilastatin-sensitive metallo-peptidase. Of the two hydrolysis products,d-aspartate was found to be less accumulated than glycine. The fate ofd-aspartate was, therefore, examined and the amino acid was found to be converted tol-aspartate,l-alanine and pyruvate, in the presence ofl-glutamate. Experiments with enzyme inhibitors suggested that the conversion involvedd-aspartate oxidase, aspartate aminotransferase and alanine aminotransferase as well as decarboxylation of oxaloacetate produced fromd-aspartate. All the results indicate that the enzymes in the pig kidney can liberate thed-aspartyl residue in the peptide and convert it to the compounds readily utilizable. The finding suggests a probable metabolic pathway of thed-aspartate-containing peptide.

    The effect of cyclic AMP on expression of the major immediate-early genes and replication of human cytomegalovirus in human central nervous system cell lines (1999)

    Notes: Summary.  The effect of dibutyryl cyclic AMP (dbcAMP) on interaction of human cytomegalovirus (HCMV) with human central nervous system cell lines was examined. Activation of the major immediate-early (IE) promoter (MIEP) of HCMV by dbcAMP was observed in human neuroblastoma IMR-32 cells, but not in glioma 118MGC and astrocytoma U373-MG cells. The 19 bp repeat element in the enhancer of the MIEP was most likely to be the cis-element that responded to dbcAMP in IMR-32 cells as we expected. In IMR-32 cells activation of the MIEP led to enhanced synthesis of the major IE proteins and infectious HCMV.
