Multifunctional Phase-Transition Nanoparticles for Effective Targeted Sonodynamic-Gene Therapy Against Thyroid Papillary Carcinoma.

Introduction: In order to diagnose and treat papillary thyroid carcinoma (PTC) accurately, phase-transition nanoparticles, P@IP-miRNA (PFP@IR780/PLGA-bPEI-miRNA338-3p), was engineered. The nanoparticles (NPs) can target the tumor cells, realize the multimodal imaging, and provide sonodynamic-gene therapy for PTC.

Methods: P@IP-miRNA NPs were synthesized through double emulsification method, and miRNA338-3p was attached to the surface of the NPs by electrostatic adsorption.

Two novel mutations in the gene in a Chinese patient with arthrogryposis, renal dysfunction and cholestasis syndrome 1: A case report.

Background: The (OMIM: 608552) gene is located on chromosome 15q26.1. We found a female infant with autosomal recessive arthrogryposis, renal dysfunction and cholestasis syndrome 1 (ARCS1) caused by mutation in .

Comparison of ultrasound-guided thermal ablation and conventional thyroidectomy for benign thyroid nodules: a systematic review and meta-analysis.

To compare the safety and efficacy of ultrasound-guided thermal ablation and conventional thyroidectomy for benign thyroid nodules (TNs) by performing a systematic review and meta-analysis. We searched PubMed, Embase, Web of Science and Cochrane Library databases for clinical trials from the date of their inception to 1 April 2019. Two investigators independently examined the trials to select qualified studies, extracted relevant information and assessed the risk of bias according to the Cochrane Collaboration checklist (Oxford, UK).

A photothermal-hypoxia sequentially activatable phase-change nanoagent for mitochondria-targeting tumor synergistic therapy.

To enhance the specificity and efficiency of anti-tumor therapies, we have designed a multifunctional nanoparticle platform for photochemotherapy using fluorescence (FL) and photoacoustic (PA) imaging guidance. Nanoparticles (NPs) composed of a eutectic mixture of natural fatty acids that undergo a solid-liquid phase transition at 39 °C were used to encapsulate materials for the rapid and uniform release of the hypoxia-activated prodrug tirapazamine (TPZ) and the photosensitizer IR780, which targets the mitochondria of tumor cells and can be used to induce hypoxic cell death via photodynamic therapy and photothermal therapy. In vitro, the NPs containing TPZ and IR7890 exhibited appreciable cell uptake and triggered drug release when irradiated with a NIR laser.

A sequential targeting nanoplatform for anaplastic thyroid carcinoma theranostics.

Effective accumulation of nanoparticles (NPs) in tumor regions is one of the major motivations in nanotechnology research and that the establishment of an efficient targeting nanoplatform for the treatment of malignant tumors is urgently needed for theranostic applications. In this study, we engineered multifunctional sequential targeting NPs for achieving synergistic antiangiogenic photothermal therapy (PTT) and multimodal imaging-guided diagnosis for anaplastic thyroid carcinoma (ATC) theranostics. Antibody bevacizumab with an affinity towards vascular endothelial growth factor (VEGF) on the tumor cell surface was conjugated onto the surface of polymer NPs for VEGF targeting and antiangiogenic therapy.

Three-dimensional anatomic analysis of retrosigmoid approach with thin-section computed tomographic image.

Objective: This study aimed to locate and measure the distances between important structures of the retrosigmoid approach using both three-dimensional reconstruction technique and volume-rendering technique.

Methods: We scanned skulls of 120 volunteers to get the final result with thin-section computed tomographic image.

Results: The distance of AC was measured as 39.
