Anaplastic thyroid carcinoma (ATC) is one of the most deadly cancers. With intensive multimodalities of treatment, the survival remains low. ATC is not sensitive to (131)I therapy due to loss of sodium iodide symporter (NIS) gene expression. We have previously generated a stable human NIS-expressing ATC cell line, ARO, and the ability of iodide accumulation was restored. To make NIS-mediated gene therapy more applicable, this study aimed to establish a lentiviral system for transferring hNIS gene to cells and to evaluate the efficacy of in vitro and in vivo radioiodide accumulation for imaging and therapy. Lentivirus containing hNIS cDNA were produced to transduce ARO cells which do not concentrate iodide. Gene expression, cell function, radioiodide imaging and treatment were evaluated in vitro and in vivo. Results showed that the transduced cells were restored to express hNIS and accumulated higher amount of radioiodide than parental cells. Therapeutic dose of (131)I effectively inhibited the tumor growth derived from transduced cells as compared to saline-treated mice. Our results suggest that the lentiviral system efficiently transferred and expressed hNIS gene in ATC cells. The transduced cells showed a promising result of tumor imaging and therapy.

Based on the repertory grid technique, we developed Explore Your Meanings (EYME), a digital platform that helps patients explore identity values and internal conflicts using virtual reality (VR). EYME was part of a research project treating depression in young adults, including 10 weekly, 1-h sessions aimed at changing personal constructs-cognitive schemas that shape how individuals interpret reality. We present the case of Mary, a 21-year-old woman diagnosed with persistent major depressive disorder and social phobia.

Objectives: To assess the effect of patient positioning and general anesthesia on the condylar position in orthognathic surgery.
Materials And Methods: This prospective study included patients undergoing orthognathic surgery between 2019 and 2020. Four weeks prior to surgery (T0) cone-beam computed tomography (CBCT) scans and intra-oral scans (IOS) were acquired in an upright position.

Morphea is a chronic inflammatory fibrosing disorder. Since fibrosis is the hallmark of both scars and morphea, our attention was raised for the possible use of Fractional Ablative CO lasers and microneedling as treatment modalities for morphea. To compare the efficacy and safety of Fractional Ablative CO lasers and microneedling in the treatment of morphea.

Background: Clavicle fractures associated with ipsilateral coracoid process fractures are very rare, with limited literature reporting only a few cases. This study reports on 27 patients with ipsilateral concomitant fractures of the clavicle and coracoid process who were followed for more than 12 months.
Material And Methods: This retrospective study reviewed the charts of skeletally mature patients with traumatic ipsilateral clavicle and coracoid process fractures treated at the authors' institution.
