Chronic spontaneous urticaria (CSU) is a debilitating mast cell-driven disease characterized by recurrent wheals and/or angioedema. 1-3 Chronic spontaneous urticaria (CSU) is a disorder where symptoms of urticaria occur without an identifiable provoking factor and persist for more than six weeks. 1,2 CSU is thought to result from the pathogenic ...

2005年5月1日 · Temperature-programmed reduction (TPR), oxidation (TPO), and desorption (TPD) studies were performed on three copper–ceria mixed oxide samples having the same nominal composition, Cu 0.15 Ce 0.85 O 2−y, but prepared in three different ways: by co-precipitation, the sol–gel peroxide route, and the sol–gel citric acid route.

2025年3月9日 · Herein, inspired by the collaborative 3D catalytic centers in natural TPO, we engineer the SACs with Cu-N 5 sites on BO 2 (BO 2 /CuN 5 C) as the catalytic and binding center for achieving the TPO function simulation. We demonstrate that BO 2 /CuN 5 C can catalyze the iodination coupling of iodide and tyrosine on Tg in the presence of …

2020年11月25日 · The TPO profile of the catalyst shows two distinct minima at 20 and 30 minutes corresponding to 100 and 250 °C. These peaks are ascribed to oxidation of Cu(0) sites to Cu(I) and Cu(I) to Cu(II) sites respectively, illustrating the presence of both copper metal and copper(I) metal sites in the catalyst.

2002年1月25日 · The surface reduction and oxidation of nanocrystalline CeO 2 and CuO/CeO 2 was investigated by temperature-programmed reduction (TPR) and isothermal/temperature-programmed oxidation (TPO) measurements.

在单原子催化剂 （SAC） 中设计模拟甲状腺过氧化物酶 （TPO） 功能的三维 （3D） 催化位点以实现碘酪氨酸偶联，尽管对于甲状腺激素的合成非常可取，但提出了巨大的挑战。 在此，我们设计并合成了一类具有 3D 催化中心的 SACs，由 Cu-N 5 作为催化位点和 BO 2 作为结合位点 （BO 2 /CuN 5 C） 组成，用于模拟 TPO 激活 H 2 O 2 以促进酪氨酸碘化和共轭以产生甲状腺激素。 我们证明所制备的 BO 2 /CuN 5 C 不仅通过氢键相互作用为 H 2 O 2 提供结合位点，而且还具有 …

tpo指的是程序升温氧化，tpo技术主要用于积碳催化剂的烧碳再生考察，也有用于研究气相氧与催化剂表面吸附氢和表面氧空位的反应。 中文名 程序升温氧化

BO 2 /CuN 5 C with TPO-like catalytic centers can produce 3,3',5-triiodothyronine and d-thyroxine with 2.4-fold and 11.1-fold improvements relative to those of CuN 5 C. Besides, the assessment of 2-mercapto-1-methylimidazole and 6-propyl-2-thiouracil in vitro investigations of antithyroid drugs corresponds well with the European Thyroid ...

Designing three-dimensional (3D) catalytic sites in single-atom catalysts (SACs) that mimic thyroid peroxidase (TPO) function for achieving iodotyrosine coupling, although highly desirable for the synthesis of thyroid hormones, poses a great challenge.

Anti-TPO (anticorpii antitiroid-peroxidaza) sunt proteine produse de sistemul imunitar care ataca enzima tiroid-peroxidaza, esentiala in productia de hormoni tiroidieni in glanda tiroida. Nivelurile crescute de anti-TPO pot indica o disfunctie a glandei tiroide, ducand la inflamatie si afectarea functiei tiroidiene.
