Oxygen Attachment Dissociation of Protonated Reserpine and Its Analogs
Rapid Communications in Mass Spectrometry, Volume 40, Issue 14, 30 July 2026.ABSTRACT Rationale Carbon–carbon double bonds are ubiquitous structural motifs in natural products and pose a key challenge in locating their presence in analytes via MS‐based methods. Here, we use the alkaloid reserpine as a model system to examine whether OAD reactions can locate quaternary double bonds embedded in fused multicyclic structures ...

On radiation situation in vicinity of PET production cyclotron [PDF]
EPJ Web of ConferencesThe medical cyclotrons intended for the production of medical isotopes are relatively widespread. The most common radioisotope product of these facilities is 18F which origins from 18O(p, n)18F reaction. Due to relatively large amounts of produced nuclei,

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 6, Page 645-656, July 2026.ABSTRACT The European rabbit (Oryctolagus cuniculus) plays a key ecological role in Mediterranean ecosystems, yet its populations are declining. Two subspecies, O. c. algirus and O. c. cuniculus, are present in the Iberian Peninsula and exhibit genetic, phenotypic, and ecological differences.

A Step‐by‐Step Protocol From METASPACE to Biological Interpretation
Journal of Mass Spectrometry, Volume 61, Issue 7, July 2026.ABSTRACT Mass spectrometry imaging (MSI) represents an exceptional tool for exploring complex biological systems spatially at the molecular level. However, its multidimensional nature and large data outputs make it challenging to extract meaningful biological insights. Advancements such as the METASPACE platform allow researchers to efficiently process,

Journal of Mass Spectrometry, Volume 61, Issue 7, July 2026.ABSTRACT Genome sequencing is the gold standard for microbial identification. However, it fails to distinguish closely related species with overlapping genetic features. This is the case of Bacillus cereus and Bacillus cytotoxicus, two members of the B. cereus group with distinct pathogenic profiles. While B. cereus, a well‐known opportunistic pathogen
