Purpose: To evaluate changes in thyroid function post-thermal ablation (TA) of thyroid nodules and to identify risk factors associated with post-ablation thyroid function abnormalities.
Materials And Methods: A retrospective analysis of 2,264 cases treated with TA between June 2015 and July 2024 was conducted, including 1,169 benign thyroid nodules (BTNs) and 1,095 papillary thyroid carcinoma (PTC) cases. Thyrotropin (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) levels were measured before treatment and at 1, 3, 6, 9, and 12 months post-ablation.

Abnormalities in resting-state brain activity have been demonstrated in depression patients with different ages, yet the age-related changes in dynamics of brain activity in depression are still limited. Here, we investigated the impacts of age on dynamics of brain activity and the molecular architecture. Resting-state functional magnetic resonance images were obtained from 138 first-episode depression patients and 120 healthy volunteers.

Studies have shown that T cells, by secreting pro-inflammatory cytokines such as interferon-gamma (IFN-γ), Interleukin-17 (IL-17), and Tumor necrosis factor-alpha (TNF-α), directly lead to vascular dysfunction and elevated blood pressure. The activation of Th1 and Th17 cell subsets, along with the dysfunction of regulatory T cells (Tregs), is a critical mechanism in the onset and progression of hypertension.

Lignin is an abundant and cost-effective aromatic polymer, which makes the production of high-value aromatic aldehydes from it highly significant. However, a challenge is that these aldehydes can easily over-oxidation into aromatic acids during aerobic oxidation. Therefore, preventing over-oxidation is crucial.

Methods: Hepatic IR was assessed by the hepatic insulin resistance index (HIRI).
Natural topological proteins exhibit unique properties including enhanced stability, controlled quaternary structures, and dynamic switching properties, highlighting topology as a unique dimension in protein engineering. Although artificial design and synthesis of topological proteins have achieved certain success, their diversity and complexity remain rather limited due to the scarcity of available entangling motifs essential for the construction of nontrivial protein topologies. In this work, we developed a deep-learning model to predict the entanglement features of a homodimer based solely on its amino acid sequence via the Gauss linking number matrices.
