Multifocality increases the risk of central compartment lymph node metastasis but is not related to the risk of recurrence and death in papillary thyroid carcinoma.

Background: Multifocality is a distinctive feature of papillary thyroid carcinoma (PTC); however, the biological behavior of PTC and its optimal management strategy remain unclear. The aim of this study was to analyze the clinical features and prognostic differences of multifocal papillary carcinoma and to guide the precise treatment of multifocal papillary carcinoma.

Methods: The medical records of 1,139 patients with PTC who had undergone total or hemi-thyroidectomy between April and October 2013 at the Tianjin Medical University Cancer Institute and Hospital were reviewed.

A CD26 tendon stem progenitor cell population contributes to tendon repair and heterotopic ossification.

Inadequate tendon healing and heterotopic bone formation result in substantial pain and disability, yet the specific cells responsible for tendon healing remain uncertain. Here we identify a CD26 tendon stem/progenitor cells residing in peritendon, which constitutes a primitive stem cell population with self-renewal and multipotent differentiation potentials. CD26 tendon stem/progenitor cells migrate into the tendon midsubstance and differentiation into tenocytes during tendon healing, while ablation of these cells led to insufficient tendon healing.

Radical-Triggered Bicyclization and Aryl Migration of 1,7-Diynes with Diphenyl Diselenide for the Synthesis of Selenopheno[3,4-]quinolines.

The translocation of an aryl group from selenium into carbon enabled by the cleavage of the C-Se bond is reported by using nitrogen atom-linked 1,7-diynes and diaryl diselenides as starting materials, leading to various selenophene derivatives in a regioselective manner. This method enables the construction of two C-Se bonds and two C-C bonds through sequential radical bicyclization and 1,2-aryl migration under metal-free conditions. Control experiments and mechanistic studies suggest that this reaction proceeds through the cleavage of the inert C(Ph)-Se bond, facilitating the aryl translocation process.

Unveiling mitochondrial mysteries: Exploring novel tRNA variants in type 2 diabetes mellitus.

The recent study of Ding provides valuable insights into the functional implications of novel mitochondrial tRNA and tRNA variants in type 2 diabetes mellitus (T2DM). This editorial explores their findings, highlighting the role of mitochondrial dysfunction in the pathogenesis of T2DM. By examining the molecular mechanisms through which these tRNA variants contribute to disease progression, the study introduces new targets for therapeutic strategies.

Advancing treatment strategies: Insights from network meta-analysis of hepatic arterial infusion chemotherapy for advanced hepatocellular carcinoma.

This study examines the pivotal findings of the network meta-analysis of Zhou , which evaluated the efficacy of hepatic arterial infusion chemotherapy and combination therapies for advanced hepatocellular carcinoma (HCC). This meta-analysis suggests that therapeutic combinations have greater efficacy than do standard treatments. The article highlights the key insights that have the potential to shift current clinical practice and enhance outcomes for patients with advanced HCC.
