One-week test-retest recordings of resting cardiorespiratory data for reliability analysis.

Heart rate variability (HRV) is a key indicator of cardiac autonomic function, making reliable assessment crucial. To examine the test-retest stability of resting HRV in healthy individuals, fifty participants attended two lab sessions within a week, at the same time of day. After a 5-minute acclimatization period, electrocardiogram and respiration were recorded at rest.

Cryogenic sample eject system for electron paramagnetic resonance spectrometers.

We present a fully automated cryogenic sample insertion and ejection system for use with low-temperature EPR probes. We show how the system can be implemented on a conventional EPR spectrometer and that ejection and insertion is reliably possible at temperatures down to 10 K. Furthermore, we investigate the glass properties of a 0.

Induced B-Cell Receptor Diversity Predicts PD-1 Blockade Immunotherapy Response.

Immune checkpoint inhibitors such as anti-PD-1 antibodies (aPD1) can be effective in treating advanced cancers. However, many patients do not respond and the mechanisms underlying these differences remain incompletely understood. In this study, we profile a cohort of patients with locally-advanced or metastatic basal cell carcinoma undergoing aPD-1 therapy using single-cell RNA sequencing, high-definition spatial transcriptomics in tumors and draining lymph nodes, and spatial immunoreceptor profiling, with long-term clinical follow-up.

White matter differences between younger and older adults revealed by fixel-based analysis.

The process of healthy aging involves complex alterations in neural structures, with white matter (WM) changes significantly impacting cognitive and motor functions. Conventional methods such as diffusion tensor imaging provide valuable insights, but their limitations in capturing complex WM geometry advocate for more advanced approaches. In this study involving 120 healthy volunteers, we investigated whole-brain WM differences between young and old individuals using a novel technique called fixel-based analysis (FBA).
