In the NAM group, anterior crossbite was present in 121% of cases, contrasting sharply with the 238% prevalence in the non-NAM group. Maxillary arch dimensions and malocclusion in UCLP and BCLP cases were not impacted by the application of NAM therapy. The substantial difference in maxillary widths stemmed primarily from the cleft type. NAM therapy proved ineffective in modifying maxillary arch dimensions and malocclusion in individuals with both UCLP and BCLP. The cleft type's influence was paramount in creating the substantial difference in maxillary widths. The development of safe, high-quality theranostic agents for cancer treatment holds substantial clinical significance. The biocompatible poly(styrene-alt-maleic anhydride) (PSMAn) is, for the first time, employed to encapsulate indocyanine green (ICG) in a clinical setting, thereby generating the PSMAn-ICG polymer. Water, acting as a medium for hydrolysis, causes the self-assembly of ICG-labeled poly(styrene-alt-maleic acid) to form PSMA-ICG nanoparticles. The NPs, intriguingly, boast numerous benefits, such as excellent solubility and stability within aqueous mediums, superior photostability, and reduced hemolytic damage to red blood cells, underscoring the crucial role of PSMA conjugation. Interestingly, PSMA-ICG nanoparticles demonstrably augment tumor targeting and enable sustained imaging of tumor growths. In addition, the administration of PSMA-ICG NPs, coupled with near-infrared laser irradiation, demonstrates heightened effectiveness in photothermal tumor ablation techniques. Beyond that, PSMA-ICG NPs, coated with 9-amino-sialic acid (Sia), are developed, resulting in more effective tumor imaging and phototherapy procedures. The utilization of PSMA-NIR conjugates has yielded a reduction in tumor size, as reported for the first time in this study of mice. Ultimately, this research delivers novel phototheranostic agents, presenting a promising pathway for substantial clinical advancements. Polo-like kinase 4 (PLK4) inhibitors' anti-tumor effect has been investigated across various solid carcinomas, yet its usage in anaplastic thyroid cancer (ATC) is not widespread. Subsequently, this research intended to explore the effect of a PLK4 inhibitor on the malignant properties of ATC cell lines, and its concurrent anti-tumor synergy with sorafenib. C643 and 8305c cell cultures were treated with varying doses of centrinone, a PLK4 inhibitor, with and without concomitant exposure to sorafenib. Meanwhile, an assessment was made of cell viability, apoptosis, cell cycle characteristics, and the expression levels of glycogen synthase kinase-3 beta (GSK3), phosphorylated GSK3 (p-GSK3), and beta-catenin. The mRNA and protein levels of PLK4 were demonstrably higher in the majority of ATC cell lines in comparison to the normal thyroid epithelial cell line, all p-values being less than 0.05. In C643 and 8305c cells, centrinone demonstrably reduced cell viability, triggered apoptosis, halted the cell cycle at the G2/M phase, and inhibited Wnt/-catenin signaling, all in a dose-dependent fashion (all P values less than .05). Centrinone, in combination with sorafenib, exhibited a statistically significant enhancement of antitumor efficacy (P < 0.05 across all concentrations), with the optimal combination observed at 5 nM centrinone and 4 µM sorafenib in C643 cells, followed by 4 nM centrinone and 4 µM sorafenib in the same cell line. Centrinone plus sorafenib treatment demonstrated a superior effect on cell viability, apoptosis, G2/M cell cycle progression, and Wnt/-catenin signaling inhibition compared to either drug alone in both C643 and 8305c cell lines (all p-values below 0.05). A PLK4 inhibitor's antitumor effect is complemented by sorafenib, achieving synergistic outcomes through cell cycle arrest and Wnt/-catenin pathway inactivation in ATC.
