Background: The American Thyroid Association guidelines primarily recommend central neck dissection for papillary thyroid carcinoma with advanced primary tumors or clinically positive neck nodes. However, the appropriate extent of dissection remains unclear. We aimed to compare the rate of locoregional recurrence between unilateral and bilateral central neck dissection in invasive papillary thyroid carcinoma.

Against this backdrop, biodegradable plastics have emerged as viable alternatives owing to their sustainability and capacity for biodegradation. Polylactic acid (PLA) presently commands the largest market share among biodegradable plastics, finding extensive application in products such as thin films, medical materials, and biodegradable straws.

Methods: We report the case of a 31-year-old female who was identified to have multiple subcutaneous implantation of thyroid tissue 5 years after transoral endoscopic thyroidectomy vestibular approach.
The disorders of endometrial receptivity and ovulatory dysfunction are both significant causes of infertility in patients with polycystic ovary syndrome (PCOS). In this study, we investigated the expression profile and functional implications of circular RNAs (circRNAs) in the endometrial receptivity of PCOS-affected mice. Twenty-four female C57BL/6 mice were divided into PCOS and normal control groups.

Herein, a green approach to synthesize MG by methanolysis of glucose is proposed, in which the subcritical methanol and phenol/quinone redox system were combined to promote the reversible C-C cleavage and oxidation during the cascade reaction of glucose to MG.

Methods: We presented a 49-year old woman who underwent TOETVA developed delayed tracheal rupture 1 week after surgery. An extensive search of literature was carried out using PubMed, Embase, and Web of Science for studies reporting tracheal injury following endoscopic thyroidectomy.
This meta-analysis evaluates whether near-infrared autofluorescence (NIRAF) imaging reduces the risk of hypocalcemia after total thyroidectomy. A systematic literature search in PubMed, EMBASE, Web of Science, and Cochrane Library for studies from June 2011 to January 2021 comparing total thyroidectomy with NIRAF and conventional surgery (naked eye). Six eligible studies involving 2180 patients were included.

Objectives: The aim of this study is to determine the causal relationship between specific gut microbiota and abdominal obesity. Based on genome-wide association study (GWAS) summary statistics, we performed a 2-sample Mendelian randomization (MR) analysis to evaluate whether the gut microbiota affects abdominal obesity.
Biomass furfural-like compounds are chemicals that cannot be extracted from fossil materials, through which a large number of fine chemicals and fuel additives can be opened up, but one big efficiency problem during the transformation is the accumulation of oligomers. Here, we propose a novel and efficient Ru-Mo bimetallic catalyst for selective hydrogenation-rearrangement of furfural-like compounds. The result showed that an unprecedented rearrangement product selectivity of 89.

X-ray diffraction (XRD), scanning electron microscope (SEM), energy spectrometer (EDS), N adsorption-desorption (BET), and infrared spectroscopy (FTIR) were used to characterize the microstructure and surface properties of composite materials. The results show that the composite material not only has a good degradability for rhodamine B, the decolorization rate reaches 98.

However, when lateral neck dissection (LND) is required, endoscopic surgery may be challenging. Therefore, we introduced needle-assisted endoscopic technique to achieve endoscopic LND procedure and evaluated its safety and feasibility in the present study.

The mRNA of procollagen, matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs), heat-shock protein 70 (Hsp70), interleukin-6 (IL-6) and transforming growth factor beta (TGF-beta) were analyzed at 24 and 48 h post-irradiation by using RT-PCR.
