唑胺菌酯（pyrametostrobin）是沈阳科创2005年研发的新型甲氧基丙烯酸酯类杀菌剂，其结构可看作是在唑菌胺酯（吡唑醚菌酯）的吡唑环上对取代基进行重新修饰得到的，唑菌胺酯吡唑环1位上取代基是4-氯苯基，而胺唑菌酯的吡唑环1位和4位上是两个甲基，3位上取代基是苯环。结构的变化赋予了胺唑菌酯更好的光稳定性和内吸传导性。实验证明，唑胺菌酯具有很好的预防和治疗作用，具有较长的持效期和耐雨水冲刷活性，在低剂量下对马铃薯和番茄晚疫病、葡萄灰霉病、小麦和黄瓜白粉病就有很好的防治效果。

Potato milk has come and gone – is it time for the sweet potato now?Researchers at Appalachian State University are betting on it with a new project to create plant-based milk from surplus sweet potatoes.

T cells don’t simply switch on—they reshape themselves. When these immune sentinels recognize a target, they rapidly reorganize their internal scaffolding to build an immunological synapse, a nanoscale interface that determines how strongly they respond. But that architectural overhaul needs brakes. Without them, T cells risk becoming hypersensitive, reacting to weak cues, and drifting toward autoimmunity. Now, new work reveals that one of those brakes—PTPN22 (proline-serine-threonine phosphatase–interacting protein 1)—acts not only on signaling molecules but also on the cytoskeletal machinery that sculpts the synapse itself.
