Incorporating Lymph Node Size at CT as an N1 Descriptor in Clinical N Staging for Lung Cancer.

Background The ninth edition of the TNM classification for lung cancer revised the N2 categorization, improving patient stratification, but prognostic heterogeneity remains for the N1 category. Purpose To define the optimal size cutoff for a bulky lymph node (LN) on CT scans and to evaluate the prognostic value of bulky LN in the clinical N staging of lung cancer. Materials and Methods This retrospective study analyzed patients who underwent lobectomy or pneumonectomy for lung cancer between January 2013 and December 2021, divided into development (2016-2021) and validation (2013-2015) cohorts.

Effects of blood pressure lowering in patients treated with intravenous thrombolysis before endovascular thrombectomy.

Background: The effects of blood pressure (BP) lowering in patients treated with intravenous tissue plasminogen activator (IV tPA) before endovascular thrombectomy (EVT) are unclear.

Aims: This study aims to investigate whether intensive and conventional BP management affect outcomes differently, depending on IV tPA administration before EVT.

Methods: In this subgroup analysis of the Outcome in Patients Treated with Intra-Arterial Thrombectomy-Optimal Blood Pressure Control (OPTIMAL-BP; ClinicalTrials.

Optimal chemokine receptors for enhancing immune cell trafficking in adoptive cell therapy.

Recently, a strategy involving the engineering of chemokine receptors on immune cells was developed to optimize adoptive cell therapy (ACT) for solid tumors. Given the variability in chemokine secretion among different tumor types, identifying and modulating the appropriate chemokine receptors is crucial. In this study, we utilized extensive RNA sequencing data from both tumor tissues from The Cancer Genome Atlas and normal tissues from Genotype-Tissue Expression to investigate the expression profiles of chemokines.

Super-photostable organic dye for long-term live-cell single-protein imaging.

Organic dyes play a crucial role in live-cell imaging because of their advantageous properties, such as photostability and high brightness. Here we introduce a super-photostable and bright organic dye, Phoenix Fluor 555 (PF555), which exhibits an order-of-magnitude longer photobleaching lifetime than conventional organic dyes without the requirement of any anti-photobleaching additives. PF555 is an asymmetric cyanine structure in which, on one side, the indole in the conventional Cyanine-3 is substituted with 3-oxo-quinoline.
