Early detection of recurrent laryngeal nerve damage using intraoperative nerve monitoring during thyroidectomy.

Objective: This study aimed to investigate risk factors for early recurrent laryngeal nerve (RLN) damage during thyroid surgery with intraoperative nerve monitoring (IONM) technology to avoid RLN damage during surgery.

Methods: Data were retrospectively collected from 93 patients who underwent thyroidectomy at Beijing Hospital. All operations were performed by the same surgeon.

A Ferrite Synaptic Transistor with Topotactic Transformation.

Hardware implementation of artificial synaptic devices that emulate the functions of biological synapses is inspired by the biological neuromorphic system and has drawn considerable interest. Here, a three-terminal ferrite synaptic device based on a topotactic phase transition between crystalline phases is presented. The electrolyte-gating-controlled topotactic phase transformation between brownmillerite SrFeO and perovskite SrFeO is confirmed from the examination of the crystal and electronic structure.

[Expression of Raf kinase inhibitor protein and its significance in invasion and metastasis of hepatocellular carcinoma].

Objective: To investigate the expression of RKIP, p65 and pERK in hepatocellular carcinoma (HCC) and theIr correlation with invasion and metastasis of HCC.

Methods: Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the expression of RKIP mRNA. The expression levels of RKIP, p65 and pERK proteins in HCC tumor and peritumoral tissues were determined by immunohistochemistry and Western blot analysis.
