Prognostic value of ground-glass opacity on computed tomography for patients with pathological stage IA3 lung adenocarcinoma: a multicenter retrospective cohort study.

Background: Ground-glass opacity (GGO) on computed tomography (CT) has been suggested as a potential prognostic factor in lung adenocarcinoma (LUAD), but its significance in patients with pathological stage IA3 LUAD, particularly in relation to micropapillary (MIP) status, remains unclear. This study addresses the clinical need to stratify patients based on GGO and MIP status to optimize prognosis prediction and follow-up strategies.

Methods: A multicenter retrospective study was conducted on 411 patients with pathological stage IA3 LUAD, enrolled between July 2012 and July 2020.

Voxel-Based Morphometry and Subfield Volumetry Analysis Reveal Limbic System Involvement in Tinnitus.

Background And Purpose: Tinnitus is a condition in which individuals perceive sounds, such as ringing or buzzing, without any external source. Although the exact cause is not fully understood, recent studies have indicated the involvement of nonauditory brain structures, including the limbic system. We aimed to compare the volumes of specific brain structures between patients with tinnitus and controls.

Effect of nanoparticulate CaCO on the biological properties of calcium silicate cement.

This study aimed to evaluate the effects of nanoparticulate CaCO (NPCC) on the biological properties of calcium silicate-based cements (CSCs), including their cytotoxicity, in vitro osteogenic activity, and interactions with rat femur tissue. The average size of NPCC was 90.3±26.

Isolation and Characterization of Bioactive Compounds from sp. CMS18 and Their Antifungal Properties.

In this study, metagenomic analysis was employed to investigate the bacterial communities in the Muan tidal mudflat of the Republic of Korea. We used metagenomic analysis to identify the microbial community in tidal soil dominated by Proteobacteria. From this environment, the bacterial strain, sp.

Structural Elucidation and Antiviral Properties of Pannosides from the Halophyte L.

Four previously undescribed pentacyclic triterpenoid saponins, pannosides F-I (-), were isolated from the halophyte L. (), and their chemical structures were elucidated using 1D and 2D NMR spectroscopy and mass spectrometry. Comprehensive structural analysis revealed the presence of distinct aglycone and glycosidic moieties, along with complex acylation patterns.
