Rapid High-Sensitivity Analysis of Methane Clumped Isotopes (ΔCHD and ΔCHD) Using Mid-Infrared Laser Spectroscopy.
Anal Chem

Laboratory for Air Pollution/Environmental Technology, Empa, 8600 Dübendorf, Switzerland.
Mid-infrared laser absorption spectroscopy enables rapid and nondestructive analysis of methane clumped isotopes. However, current analytical methods require a sample size of 20 mL STP (0.82 mmol) of pure CH gas, which significantly limits its application to natural samples.

January 2025
Division of Gastroenterology, Mayo Clinic, Jacksonville, FL, USA.
Background/aims: Multiple rapid swallows (MRS) is a provocative test during high-resolution esophageal manometry (HRM) to evaluate contraction reserve (CR). This study aims to determine the prevalence of CR in patients with ineffective esophageal motility (IEM) and MRS performed in the upright position, and to assess the ideal number of MRS sequences.
Methods: We enrolled adult patients diagnosed with IEM according to the Chicago classification version 4.
Imaged capillary isoelectric focusing and online mass spectrometry for milk whey protein characterization in dairy products.

Characterizing major bovine milk proteins, including whey and casein, is of significant interest in the dairy industry. The diverse array of protein proteoforms can be different in terms of genetic variation, breed ways, lactation stage, and animal nutritional status. Current routine methods for bovine milk protein profiling are typically based on immunological techniques, infrared spectroscopy, slab gel isoelectric focusing, capillary electrophoresis, and high-performance liquid chromatography.

Although the Rare Earth (RE)FeB type magnets were invented in the 1980s and are widely used worldwide. Yet, the phase formation and dissolution mechanisms are still not crystal clear. The reaction dynamics between rare earth elements (REE) and the iron-enriched matrix are essential to understanding the formation of hard magnetic REE-Fe-B phase or, conversely, phase dissociation and performance degeneration.

Biol Imaging
December 2024
Visual Information Laboratory, University of Bristol, Bristol, UK.
Optical coherence tomography (OCT) and confocal microscopy are pivotal in retinal imaging, offering distinct advantages and limitations. OCT offers rapid, noninvasive imaging but can suffer from clarity issues and motion artifacts, while confocal microscopy, providing high-resolution, cellular-detailed color images, is invasive and raises ethical concerns. To bridge the benefits of both modalities, we propose a novel framework based on unsupervised 3D CycleGAN for translating unpaired OCT to confocal microscopy images.
