Mechanical stress in a solid ellipsoid model of the lung after thoracoscopic surgery for spontaneous pneumothorax.

Background: Newly formed bullae after video-assisted thoracoscopic surgery (VATS) bullectomy in primary spontaneous pneumothorax (PSP) are an important etiology for recurrence and are associated with mechanical stress along the stapling line. However, the distribution or pattern of stress after VATS bullectomy has not been thoroughly investigated. Our aim was to analyze the stress distribution following lung resection.

Synthesis of trypsin-protected CsPbCl fluorescent nanocrystals for hydroxyl radical sensing.

Water-dispersible perovskite nanocrystals (PNCs) show promising applications in recognizing ionic and molecular species because of their excellent optical properties. However, lead halide PNCs have some limitations when they are used as probes for molecular species sensing in aqueous media. Here, we introduce trypsin (Try) as a bioligand for the synthesis of cesium lead chloride (CsPbCl) PNCs with high water stability.

Risk factors for iliac limb migration after endovascular infrarenal aortic repair.

This study investigated anatomical and procedural factors influencing iliac limb migration and its correlation with late type 1b and type 3 endoleaks. We analyzed data of 141 iliac limbs from 91 patients who underwent endovascular aneurysm repair for infrarenal abdominal aortic aneurysm between 2005 and 2017. Iliac limb migration was measured using initial and follow-up computed tomography angiography scans conducted at least three years post-procedure, with significant migration defined as a change of ≥ 5 mm.

Nanoscale Resolution Imaging of Whole Mouse Embryos Using Expansion Microscopy.

Nanoscale imaging of whole vertebrates is essential for the systematic understanding of human diseases, yet this goal has not yet been achieved. Expansion microscopy (ExM) is an attractive option for accomplishing this aim; however, the expansion of even mouse embryos at mid- and late-developmental stages, which have fewer calcified body parts than adult mice, is yet to be demonstrated due to the challenges of expanding calcified tissues. Here, we introduce a state-of-the-art ExM technique, termed whole-body ExM, that utilizes cyclic digestion.

Dual responsive phase behavior of nonionic cellulose-based polymer brushes by visible-light-driven organocatalyzed atom transfer radical polymerization.

This single-center, single-arm, prospective cohort study enrolled individuals with weekly heartburn or acid regurgitation and confirmed erosive esophagitis.

A Dynamic Shift in Estrogen Receptor Expression During Granulosa Cell Differentiation in the Ovary.

This study uncovers a dynamic shift in estrogen receptor expression during granulosa cell (GC) differentiation in the ovary, highlighting a transition from estrogen receptor alpha (ESR1) to estrogen receptor beta (ESR2). Using a transgenic mouse model with Esr1-iCre-mediated Esr2 deletion, we demonstrate that ESR2 expression is absent in GCs derived from ESR1-expressing ovarian surface epithelium (OSE) cells. Single-cell analysis of the OSE-GC lineage reveals a developmental trajectory from Esr1-expressing OSE cells to Foxl2-expressing pre-GCs, culminating in GCs exclusively expressing Esr2.

Lung cancer organoid-based drug evaluation models and new drug development application trends.

Lung cancer is a malignant tumor with high incidence and mortality rates in both men and women worldwide. Although anticancer drugs are prescribed to treat lung cancer patients, individual responses to these drugs vary, making it crucial to identify the most suitable treatment for each patient. Therefore, it is necessary to develop an anticancer drug efficacy prediction model that can analyze drug efficacy before patient treatment and establish personalized treatment strategies.
