Differences in Needle Characteristics Between Leader and Return-stroke Stages of Positive Cloud-to-ground Lightning

open access: yes应用气象学报
Needle discharges, characterized by fine-scale filamentary plasma structures within lightning channels, represent a key manifestation of localized electric field intensification and intricate channel dynamics. Although previous case studies have reported

Methylation biomarkers can distinguish pleural mesothelioma from healthy pleura and other pleural pathologies

open access: yesMolecular Oncology, EarlyView.
We developed and validated a DNA methylation–based biomarker panel to distinguish pleural mesothelioma from other pleural conditions. Using the IMPRESS technology, we translated this panel into a clinically applicable assay. The resulting two classifier models demonstrated excellent performance, achieving high AUC values and strong diagnostic accuracy.

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins

open access: yesFEBS Open Bio, EarlyView.
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...
