Imaging mass spectrometry (IMS) is increasingly used for drug discovery and development to understand target enagement, tissue distribution, drug toxicity, and disease mechanisms, etc. However, this is still a relatively new technique that requires further development validation before it will be an acceptable technique to support regulated development of new drugs. Thus, best practices will need to be established to build more confidence and gain wider acceptance by the scientific community, pharmaceutical industry, and regulatory authorities. The Imaging Mass Spectrometry Society (IMSS) and the Japan Association for Imaging Mass Spectrometry (JAIMS) have conducted a thorough survey to gather information on the current state of IMS and to identify key issues. The survey was sent to researchers or managers in the position who are currently using IMS techniques in support of their drug discovery and development efforts and/or who plan to use such tools as best practices are established. The survey probes questions related to details regarding technical aspects of IMS, which includes data acquisition, data analysis and quantitation, data integrity, reporting, applications, and regulatory concerns. This international survey was conducted online through the Survey Monkey (https://www.surveymonkey.com) in both English and Japanese from September 14 through September 30, 2020.

HDL-associated vitamin D binding protein levels are inversely associated with necrotic plaque burden in psoriasis.

Atheroscler Plus

March 2025

Section of Inflammation and Cardiometabolic Diseases, National Heart, Lung and Blood Institute, National Institutes of Health, Bethesda, MD, USA.

Background And Aims: Vitamin D binding protein (DBP) serves a dual function as a vitamin D carrier and actin scavenger. Free DBP is present in high concentrations in serum, while a smaller pool is bound to lipoproteins like HDL and VLDL. The role of DBP's interaction with lipoproteins remains unclear.

Extracellular vesicles of PCM 2675 and PCM 489: an introductory characteristic.

Extracell Vesicles Circ Nucl Acids

November 2024

Department of Comparative Biochemistry and Bioanalytics, Faculty of Biochemistry, Biophysics and Biotechnology, Jagiellonian University, Kraków 30-387, Poland.

Extracellular vesicles (EVs) are involved in intercellular and interkingdom communication in the complex communities that constitute the niche-specific microbiome of the colonized host. Therefore, studying the structure and content of EVs produced by resident bacteria is crucial to understanding their functionality and impact on the host and other microorganisms. Bacterial EVs were isolated by differential centrifugation, their size and concentration were measured by transmission electron microscopy and nanoparticle tracking analysis, and the cargo proteins were identified by liquid chromatography coupled to tandem mass spectrometry.

Diagnostic challenges in differentiating mediastinal tuberculosis from mediastinal tumors: A case report.

Respir Med Case Rep

December 2024

Department of Pulmonology & Respiratory Medicine, Faculty of Medicine, Universitas Sumatera Utara, Prof. dr. Chairuddin P. Lubis Universitas Sumatera Utara Hospital, Jl. Dr. Mansur No. 5, Medan, 20155, Indonesia.

Mediastinal tuberculosis poses significant diagnostic challenges due to its nonspecific clinical and radiological features, particularly in high TB incidence regions like Indonesia. Here, we present the case of A 17-year-old male, initially diagnosed with a mediastinal tumor, was later confirmed to have mediastinal tuberculosis (TB). Despite normal lab results, imaging revealed a right parahilar mass.

Relationships of eating behaviors with psychopathology, brain maturation and genetic risk for obesity in an adolescent cohort study.

Nat Ment Health

January 2025

Social, Genetic and Developmental Psychiatry Centre, Institute of Psychiatry, Psychology and Neuroscience, King's College London, London, UK.

Unhealthy eating, a risk factor for eating disorders (EDs) and obesity, often coexists with emotional and behavioral problems; however, the underlying neurobiological mechanisms are poorly understood. Analyzing data from the longitudinal IMAGEN adolescent cohort, we investigated associations between eating behaviors, genetic predispositions for high body mass index (BMI) using polygenic scores (PGSs), and trajectories (ages 14-23 years) of ED-related psychopathology and brain maturation. Clustering analyses at age 23 years ( = 996) identified 3 eating groups: restrictive, emotional/uncontrolled and healthy eaters.

Objectives: Subclinical myocardial involvement is common in systemic lupus erythematosus (SLE), but differences between new onset and longstanding SLE are not fully elucidated. This study compared myocardial involvement in new onset versus longstanding SLE using cardiovascular magnetic resonance (CMR).

Materials And Methods: We prospectively enrolled 24 drug-naïve new onset SLE patients, 27 longstanding SLE patients, and 20 healthy controls.
