The common marmoset (Callithrix jacchus), a small new world monkey species, has been widely used in various scientific fields. It is necessary to understand connections between specific genotypes, their structure, and function;however, an anatomical atlas of the entire body of the common marmoset has not yet been reported. In addition to conventional absorption, refraction enhanced computed tomography (CT) based on synchrotron radiation can increase the contrast of boundaries between small absorption differences. In this study, to examine the potential of creating an anatomical atlas of the whole body of the common marmoset non-invasively, we visualized an intact marmoset using synchrotron refraction enhanced CT. The cryogenic marmoset was scanned using the medical imaging beamline at the SPring-8 synchrotron radiation research facility in JAPAN. The trabecular structure, articular cartilage, cruciate ligament in the knee joint, and small airways (diameter: > 400 μm) was clearly identified with 50 μm voxel size and 37 keV x-ray energy. The structure of the heart and branching vessels in the kidneys and liver were also identified without contrast agents, and the anatomical structure of the brain was slightly visible. These results show that synchrotron refraction enhanced CT is useful for creating an anatomical atlas non-invasively, and further studies are planned that will combine refraction enhanced CT and other imaging techniques to analyse the morphology and create a complete atlas of the whole body of the common marmoset.

Purpose: This study aimed to examine whether the signal-to-noise ratio (SNR) could be increased by combining integrated slice-by-slice shimming (iShim) with a fat suppression (FS) method other than short-tau inversion recovery (STIR) in diffusion-weighted imaging (DWI) and q-space imaging (qsi). Methods: We acquired DWI images (b-values: 0 and nine steps from 400 to 10,000 s/mm2 for six axes) using a prototypical single-shot echo planar imaging sequence by combining two types of shimming (3D Shim and iShim) and two types of FS (STIR and water excitation [WE]) in 10 volunteers. In the DWI study, the SNR for each b-value, FS effect in the b0 image, and distortion in the added image (b0 - b10,000) were evaluated for the above-mentioned four imaging methods. qsi involved original DWI images. In the qsi study, the SNR was evaluated. Results: With regard to both 3D Shim and iShim, the SNRs were significantly higher when using WE than when using STIR in b0 - b900 images (p Conclusion: The combination of iShim and WE has a high SNR on qsi.

目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。
