Gut microbiome‐derived metabolites show promise in cancer research and therapy

Interdisciplinary Medicine, EarlyView.
The metabolites produced by the gut microbiome, which are subject to regulation by multiple factors, play a pivotal role in the progression of various types of cancer. These metabolites not only function as potential biomarkers for the early detection and monitoring of tumor development, but also actively participate in cancer therapeutic processes ...

Plasmonics‐Enhanced Characterization of Cervid PrP (87–114) Fragment Aggregates in Solution

Journal of Biophotonics, EarlyView.
Multimodal nanophotonics platform combining plasmon‐enhanced imaging, label‐free SERS, and optical staining reveals new insights into the aggregation of the cervid PrP (87–114) fragment, an amyloidogenic sequence linked to chronic wasting disease susceptibility.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).
