Dynamic change of polarity in spread through air spaces of pulmonary malignancies.

Spread through air spaces (STAS) is a histological finding of lung tumours where tumour cells exist within the air space of the lung parenchyma beyond the margin of the main tumour. Although STAS is an important prognostic factor, the pathobiology of STAS remains unclear. Here, we investigated the mechanism of STAS by analysing the relationship between STAS and polarity switching in vivo and in vitro.

Association between body size and atrial myopathy: Investigation using the prevalence of left atrial low-voltage areas.

Background: Left atrial low-voltage areas (LVAs) are known to be associated with atrial myopathy and atrial fibrillation (AF) recurrence after catheter ablation. However, the association between body size and prevalence of LVAs has not been fully elucidated. The purpose of this study was to clarify the association between body size and the prevalence of LVAs in patients with AF ablation.

Incidence of Angiographic Deterioration Following Inframalleolar Angioplasty and Its Impact on Outcomes in Patients With Chronic Limb-Threatening Ischemia Requiring Repeat Intervention.

Background: Clinical impact of inframalleolar (IM) angioplasty in patients with chronic limb-threatening ischemia (CLTI) is still controversial.

Methods And Results: This single-center, retrospective study included 168 patients with CLTI and tissue loss who underwent angioplasty for IM lesions. Angiographic follow up was performed at reintervention between April 2010 and December 2020.

Three-Dimensional Nanoscale Imaging of SiO2 Nanofiller in Styrene-Butadiene Rubber with High-Resolution and High-Sensitivity Ptychographic X-ray Computed Tomography.

SiO2 aggregates in styrene-butadiene rubber (SBR) were observed using ptychographic X-ray computed tomography (PXCT). The rubber composites were illuminated with X-rays focused by total reflection focusing mirrors, and the ptychographic diffraction patterns were collected using a CITIUS detector in the range of -75° to +75° angle of incidence. The projection images of the rubber composites were reconstructed with a two-dimensional resolution of 76 nm, and no significant structural changes were observed during the PXCT measurements.
