Abstract Cellular senescence has been perceived as a barrier against carcinogenesis. However, the senescence-associated secretory phenotype (SASP) of senescent cells can promote tumorigenesis. Here, we show tumour are frequently present in front region collective invasion papillary thyroid carcinoma (PTC), well lymphatic channels and metastatic foci lymph nodes. In vitro analysis, exhibit high ability compared with non-senescent through SASP expression. Collective PTC is led by characterized...

B-RafV600E mutant is found in 40–70% of papillary thyroid carcinoma (PTC) and has an important role the pathogenesis PTC. The sodium iodide symporter (NIS) integral plasma membrane glycoprotein that mediates active transport into follicular cells, been known to be associated with loss NIS expression. In this study, we inhibited expression by upregulation its promoter methylation, specific regions CpG islands harboring PTC were highly methylated compared surrounding normal tissue. Although...

Abstract Background Congenital muscular torticollis (CMT) is characterized by thickening and/or tightness of the unilateral sternocleidomastoid muscle (SCM), ending up with torticollis. Our aim was to identify differentially expressed genes (DEGs) and novel protein interaction network modules CMT, discover relationship between gene expressions clinical severity CMT. Results Twenty-eight muscles (SCMs) from 23 subjects CMT 5 SCMs without were allocated for microarray, MRI, or...

We evaluated the utility of VE1 antibody that can detect a mutant protein resulting from BRAF V600E mutation as diagnostic tool for thyroid fine-needle aspiration cytology (FNAC).We performed immunocytochemistry on 202 FNAC specimens surgically confirmed nodules. The results were compared with molecular analyses in these matched their corresponding histology.Diagnoses included benign (9.4%), atypia undetermined significance/follicular lesion significance (11.4%), follicular...

Radiofrequency ablation (RFA) and ethanol (EA) are effective safe for benign symptomatic thyroid nodules (BSTNs). However, relatively little is known about the effects of these procedures on patients' quality life (QoL). This prospective, multicenter study evaluated RFA EA changes in thyroid-specific QoL patients with BSTNs assessed volume reduction safety procedures.Eighty-six consecutive 86 were prospectively included from two medical centers. was performed 55 solidity ≥50% 31 <50%. using...

BACKGROUND Thyroid-stimulating hormone (TSH), which is regulated by the negative feedback of triiodothyronine (T3) and thyroxine (T4), affected cortisol (a stress hormone) cytokines during allostasis. Thus, we assessed changes in TSH levels under its potential as a marker patients lacking T3 or T4 after thyroid surgery. MATERIAL AND METHODS Three questionnaires (Korean version Daily Stress Inventory, Social Readjustment Rating Scale, Overload Scale-Short [SOSS]), an open-ended questionnaire...

Studies investigating the correlation between particulate matter (PM) concentrations measured by a light scattering (LS) device and environmental factors are crucial to identify LS values with significant errors. Herein, relationship PM2.5 obtained through beta attenuation monitoring (BAM) was examined respect seven factors. Machine learning (ML) general statistical methods were employed reveal complex relationships. Data from five cities initially analyzed understand association BAM...

Abstract Calcification is important for the diagnosis of papillary thyroid carcinoma (PTC). Runt-related transcription factor 2 (RUNX2), a master associated with osteogenic differentiation, reportedly related to PTC calcification and invasiveness. However, its regulatory role in this process somewhat uncharacterized. Here, we attempted identify genes that regulate RUNX2 clarify function carcinogenesis calcification. The expression RUNX2-upstream was evaluated by real-time PCR Nthy-Ori 3-1...

Recently, VE1, a monoclonal antibody against the BRAFV600E mutant protein, has been investigated in terms of its detection mutation. Although VE1 immunostaining and molecular methods used to assess papillary thyroid carcinoma surgical specimens are good agreement, evaluation cytology samples is rarely performed, diagnostic value not well established. In present study, we explored immunoexpression from ex vivo order minimize limitations low cellularity sampling/targeting errors originated...

Abstract The incidence rates of structural persistent disease (PD) and recurrent (RD) after thyroidectomy, their clinicoradiological (CT) characteristics, remain poorly understood. Therefore, we characterized differentiated thyroid cancer (DTC) patients who underwent re-operations, with a focus on preoperative CT scans. We examined neck scans obtained prior to initial surgery reoperation, classified the into four categories according persistence/recurrence dissection/non-dissection status....
