Recent progress in silk fibroin-based flexible electronics.

With the rapid development of the Internet of Things (IoT) and the emergence of 5G, traditional silicon-based electronics no longer fully meet market demands such as nonplanar application scenarios due to mechanical mismatch. This provides unprecedented opportunities for flexible electronics that bypass the physical rigidity through the introduction of flexible materials. In recent decades, biological materials with outstanding biocompatibility and biodegradability, which are considered some of the most promising candidates for next-generation flexible electronics, have received increasing attention, e.

Effect of prostaglandin A1 and A2 on thyrotropin secretion in rats.

The effects of prostaglandin A1 and A2 (PG A1, A2) on secretion of thyrotropin (TSH) in vivo and in vitro were studied. Hundred micrograms per kg of PG A1 and A2 were injected i. v.

Stimulatory effect of PMRPamide (Phe-Met-Arg-Phe-NH2) on thyrotropin secretion in rats.

The effect of PMRPamide (Phe-Met-Arg-Phe-NH2) on thyrotropin (TSH) and thyrotropin-releasing hormone (TRH) secretion in rats was studied. PMRPamide (600 micrograms/kg) was injected i.v.
