组胺是一种咪唑，通常也被称为生物胺，尽管它的生物化学与儿茶酚胺和吲哚胺相去甚远。】 Catecholamine Transmitters The catecholamine transmitters—dopamine, norepinephrine, and epinephrine—are all synthesized from the ...
PPGL 患者的主要临床表 现为儿茶酚胺 (catecholamine ，CA) 类物质分泌增多，进一步导致高血压及心、脑、肾血管并发症 和代谢性改变，在经准确诊断后，可通过手术治疗，属于一种可治愈的继发性 ...
Obesity is associated with blunted β-adrenoreceptor (β-AR)-mediated lipolysis and lipid oxidation in adipose tissue, but the mechanisms linking nutrient overload to catecholamine resistance are poorly ...
茶氨酸含量约为新茶的1～2%左右，其含量随发酵过程减少 一般认为人体*的调节是受中枢和末梢神经递质儿茶酚胺(catecholamine)及5-羟色胺分泌量的影响。研究证明茶氨酸能有效的降低大鼠自发性*。
在这里，研究者评估了儿茶酚甲基转移酶(COMT)在胶质瘤治疗中的作用，COMT是一种降解儿茶酚胺的关键酶，也是帕金森病的药物靶点。TCGA数据分析 ...
