Use of the specific binding ratio distribution to characterise multiple system atrophy in advanced iodine-123-labelled N-(3-fluoropropyl)-2β-carbomethoxy-3β-(4-iodophenyl) nortropane serotonin transporter imaging.

Objectives: Sudden death in multiple system atrophy (MSA) is caused by decreased serotonergic innervation, but there is no routine test method for this decrease. In addition to dopamine transporters, iodine-123-labelled N-(3-fluoropropyl)-2β-carbomethoxy-3β-(4-iodophenyl) nortropane (I-FP-CIT) binds serotonin transporters (SERTs). We noted a binding potential to quantify the total quantity of I-FP-CIT binding to its receptors.

Design and synthesis of novel triazine derivatives as antimalarial agents.

In a previous study, we reported that nilotinib, a BCR-ABL tyrosine kinase inhibitor, possesses moderate antimalarial activity against PfK1 and PfFCR3. As a part of our efforts to develop novel antimalarial agents, a series of novel triazine analogs was identified as potent antimalarial agents via structure modification of nilotinib. Compound 15a showed strong antimalarial activities against PfK1 and PfFCR3 with IC values of 0.

Flattened red nucleus in progressive supranuclear palsy detected by quantitative susceptibility mapping.

Introduction: Progressive supranuclear palsy (PSP) involves midbrain structures, including the red nucleus (RN), an iron-rich region that appears as a high-contrast area on quantitative susceptibility mapping (QSM). RN may serve as a promising biomarker for differentiating parkinsonism. However, RN deformation in PSP remains elusive.

Electrolyte Effects on Electrochemical CO Reduction Reaction at Sn Metallic Electrode.

Understanding the electrolyte factors governing the electrochemical CO reduction reaction (CORR) is fundamental for selecting the optimized electrolyte conditions for practical applications. While noble metals are frequently studied, the electrolyte effects on the CORR on Sn catalysts are not well explored. Here, we studied the electrolyte effect on Sn metallic electrodes, investigating the impact of electrolyte concentration, cation identity, and anion properties, and how it shapes the CORR activity and selectivity.
