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).

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.

The Management of Parkinson's Disease Before, during and after Pregnancy—an MDS Scientific Issues Committee Review

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Pregnancy after a Parkinson's diagnosis presents complex challenges. Due to the paucity of literature, there is no evidence‐based guidelines and protocols for preconception care, management of pregnancy, childbirth and the postpartum period in women with early‐onset Parkinson's disease (PD).

Evaluation of Immunosuppressive Status Among HIV‐Positive Women With Cervical Cancer at Queen Elizabeth Central Hospital, Malawi

open access: yesMedicine Advances, EarlyView.
This study found that cervical cancer does not significantly affect HIV viral load or systemic immune suppression in HIV‐positive women, most of whom were virally suppressed. However, age, cancer stage, and socio‐economic status were significantly associated with immunological markers, with older women and those with advanced disease showing poorer HIV

Attribute Implication Bases From Galois Connection Structures

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Modeling knowledge systems by determining relationships among key variables have been and currently is a fundamental and nontrivial challenge in real‐world scenarios. Many approaches have been developed to reach this goal, but many of them are heuristic and require of alternative procedures to provide robust and tractable rules.
