We have previously demonstrated that hippocampal cholinergic neurostimulating peptide (HCNP)-related components accumulate in almost all Hirano bodies in Sommer's sector of the hippocampus of elderly individuals, and that the number of HCNP-positive Hirano bodies is greater in patients with Alzheimer's disease. Although Hirano bodies occur preferentially in(More)
The sequence Arg37-Arg38 of tyrosine hydroxylase (TH) is known to play a significant role in the feedback inhibition by the end product DA. To clarify how deeply the sequence Arg37-Arg38 and the phosphorylated Ser40 of human TH type 1 (hTH1) are involved in the regulation of this feedback inhibition in mammalian cells, we generated the following mutants:(More)
SUMMARY The usefulness of thallium-201 myocardial imaging in assessing right ventricular (RV) overloading was evaluated and compared with the electrocardiographic and hemodynamic measurements. Multiple unprocessed photoscans were obtained using a gamma camera in 47 patients who had chronic RV overload, including 28 subjects with pressure overload, 14 with(More)
BACKGROUND Right ventricular (RV) function is an independent predictor of clinical outcomes in patients with pulmonary arterial hypertension (PAH). However, it remains controversial which RV parameter should be measured as an appropriate index for the treatment of PAH. The aim of this study was to identify the most useful parameter that correlates with(More)
