Analytical Approaches to Address Challenges in the Analysis of Cannabinoids in Vascular Matrices Using Mass Spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Phytocannabinoids are bioactive metabolites derived from the Cannabis sativa plant. They have garnered attention due to their recreational uses and therapeutic potential. Although various analytical strategies have been employed for their analysis, mass spectrometry (MS) coupled to chromatographic separation is superior due to its sensitivity ...

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

open access: yesMass 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).

[Forensic medical examination of "5.8" Shenzhen air crash].

open access: yesFa yi xue za zhi, 2003
The air crash of B-2928 on May 8 1997 in Shenzhen was reported, which caused 35 dead and 37 wounded. The interval and cause of death, degree of injuries, cause of the accident and individual identification were investigated. Forensic measures to deal with such tragedies were suggested and discussed.

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

Ion Activation Methods for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

The Impact and Reliability of Tissue Segmentation on In Vivo Magnetic Resonance Spectroscopy Metabolite Quantification

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Quantification of metabolite concentrations using MRS requires tissue‐dependent signal corrections. Accurate estimation of voxel tissue composition is therefore essential. Commonly used brain tissue segmentation tools differ in their algorithms and implementation, potentially introducing variability in MRS‐derived concentration ...

A Smile From the Past: Exploring a Fixed Bone Dental Bridge From Eighteenth/Nineteenth Century Porto (Portugal)

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT This paper presents the first documented case of a fixed bone dental bridge in Portugal. This item was recovered alongside the remains of a young adult individual of indeterminate sex from the 19th century burial site of the 3rd Order of Our Lady of Carmo in Porto, Portugal.
