We report a simple design strategy for wideband uniform-rate smooth truncation (WURST) pulses that enables ultrafast frequency sweeps to maximize the sensitivity of Carr-Purcell-Meiboom-Gill (CPMG) acquisition in static wideline nuclear magnetic resonance (NMR). Three compelling examples showcase the advantage of ultrafast frequency sweeps over currently employed WURST-CPMG protocols, demonstrating the potential of investigating materials that are typically inaccessible to static wideline NMR techniques, e.g.

Methods: Ten patients at > 5% risk for lymph node (LN) invasion were included. The day before surgery, a magnetic fluorescent hybrid tracer consisting of superparamagnetic iron oxide nanoparticles (SPION) and indocyanine green was transrectally injected into the prostate.
Article Synopsis
- The study examines the effects of gender-affirming hormone therapy (estrogen and testosterone) on various clinical chemistry analytes in healthy transgender and nonbinary individuals.
- Key findings indicate that while most measures like electrolytes and urea nitrogen remained stable, certain enzymes and lipid levels shifted toward those typical for their affirmed gender, particularly in the testosterone group.
- The research highlights the need for more tailored reference intervals for transgender patients, as hormone therapy may significantly alter some lab values that differ by biological sex in cisgender individuals.
Dual-graphite batteries (DGBs), being an all-graphite-electrode variation of dual-ion batteries (DIBs), have attracted great attention in recent years as a possible low-cost technology for stationary energy storage due to the utilization of inexpensive graphite as a positive electrode (cathode) material. However, DGBs suffer from a low specific energy limited by the capacity of both electrode materials. In this work, a composite of black phosphorus with carbon (BP-C) is introduced as negative electrode (anode) material for DIB full-cells for the first time.

The aim was to identify training needs and active information opportunities in primary care by analyzing DI requests and to calculate labor cost associated with DI requests addressable with training or active information.
Methods: DI requests received in 2016 and 2017 by ambulatory care pharmacists were independently classified by 2 authors into: training (i.
