  近年来，仲氢诱导的极化侧臂氢化 (PHIP-SAH) 已应用于超极化 [1- 13 C] 丙酮酸并将其代谢转化为癌细胞中的[1- 13 C] 乳酸。在我们最近的 MINERVA 脉冲序列协议的基础上发展，我们已经实现了 27% [1- 13 C] 丙酮酸盐碳极化，我们展示了 [1,2- 13 C] 丙酮酸盐的超极化（每个13 C 自旋上约 7% 极化)通过PHIP-SAH。通过改变脉冲序列中的单个参数，MINERVA 可以在 [ 1,2-13]中增强 C1 和/或 C2 的信号C] 丙酮酸具有相反的相，允许同时监测具有增强光谱对比度的不同化学反应或通过不同碳位点的相同反应。我们首先展示了通过不同的碳位点在水溶液、体外和细胞内（HeLa 细胞）中监测 7T 下相同的酶促丙酮酸转化为乳酸的能力。在第二组实验中，我们使用 C1 和 C2 碳位置作为同步化学反应的光谱探针：通过 [1,2- 13 C]

  There is described a method for the preparation of a hyperpolarised agent, wherein said agent comprises at least one —N − , —O − or —S − moiety (optionally protonated) and a secondary binding site; said method comprising: (i) preparing a fluid containing a polarisation transfer precatalyst and parahydrogen; (ii) introducing a co-ligand to interact with the transfer precatalyst to form a polarisation transfer catalyst; (iii) applying a magnetic field or radio frequency excitation to (ii), such that hyperpolarisation is transferred from parahydrogen to a target molecule; (iv) introducing a target molecule containing at least at least one —N − , —O − or —S − moiety, in conjunction with a secondary binding to form a hyperpolarised agent; wherein the co-ligand is selected from the group consisting of one or more of a sulfoxide, a thioester, a phosphine, an amine, CO, an isonitrile and a nitrogen heterocycle.

  The production of natural flavors by means of microorganisms is of great interest for the food and flavor industry, and by-products of the agro-industry are particularly suitable as substrates. In the present study, Citrus side streams were fermented using monokaryotic strains of the fungus Pleurotus sapidus. Some of the cultures exhibited a pleasant smell, reminiscent of woodruff and anise, as well

Here, we explore the reactivity of a novel class of such catalysts based on sulfoxide containing [IrCl(H)2(carbene)(DMSO)2], which are involved in the hyperpolarisation of pyruvate using SABRE.
