使用脂质和水自旋之间的分子间零量子相干 (iZQC) 转变,对健康和肥胖小鼠的棕色脂肪组织 (BAT) 和白色脂肪组织 (WAT) 库进行非侵入性体外和体内表征。 IZQC 能够选择性地检测水和脂质自旋之间的空间相关性,从而以亚体素分辨率检测脂肪沉积物的水合。在大约 100 微米的距离范围内,观察到的主要峰位于水、1.3 ppm 处的亚甲基质子和 5.3 ppm 处的烯属质子之间。我们的体外结果表明,亚甲基-烯属 iZQC 信号在 BAT 和 WAT 中均很强,但水-亚甲基 iZQC 信号仅是 BAT 组织的特征。在体内,瘦小鼠或年轻小鼠中这些峰的比例明显高于年老或肥胖小鼠。
Brown Adipose Tissue (BAT) and White Adipose Tissue (WAT) depots are non-invasively characterized in vitro and in vivo in healthy and obese mice using intermolecular Zero-Quantum Coherence (iZQC) transitions between lipid and water spins. IZQCs enable selective detection of spatial correlation between water and lipid spins and thereby the hydration of fatty deposits with subvoxel resolution. At about a 100 micrometer distance scale, the major observed peaks are between water, methylene protons at 1.3ppm, and olefinic protons at 5.3 ppm. Our in vitro results show that the methylene-olefinic iZQC signal is strong both in BAT and in WAT, but that the water-methylene iZQC signal is characteristic only of BAT tissue. In vivo, the ratio of these peaks is substantially higher in lean or young mice than in old or obese mice.
