Dr. Xin Li is a research fellow at the Department of Urology, Graduate School of Medicine, Kyoto University where he got his Ph.D. degree. He is going to start to work at Peking University Third Hospital as a urologist in August 2021. Dr. Li is also proud to win the Young Investigator Grant in MSACL EU 2019 and to have a podium presentation of his research there. Recently, he has become a member of the Japanese Society for Biomedical Mass Spectrometry (JSBMS). While studying at Kyoto University he became interested in the clinical application of MALDI-TOF/MS, especially when using it in the urinary lipid analysis. Dr. Li and his supervisors, especially Dr. Kenji Nakayama who is an Asia Outreach Committee of MSACL and also one of the JSBMS council members, developed a simple relative-quantitative MALDI-TOF/MS system for urinary lipidomics, and they are applying it in the screening of urinary biomarkers for genitourinary disorders. Now, they are aiming at promoting the "qShot MALDI” system as a simple application for the MALDI analysis.

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) has been used for lipid analysis since the 2000s. However, the poor reproducibility and quantitative ability hinder its application in clinical biomarker screenings. To improve the clinical usage of MALDI-TOF/MS, especially for quantitative detection of the urinary phospholipids (PLs) and lysophospholipids (LPLs), we have adopted three main strategies including the selection of a proper matrix, a specially designed plate, and a spike of ionization standards. This system, named “qShot MALDI” analysis, offers a quick, qualitative, and quantitative detection of urinary PLs and LPLs. Meanwhile, a clinical application of this system was conducted for screening urine lipidomic biomarkers for prostate cancer. The results indicated that the qShot MALID system had a good performance with rapid, convenient, and reproducible properties.

MSE from the Technical University of Warsaw (Poland)
PhD from the Technical University of Denmark (Denmark)
Postdoctoral research at the University of Auckland (New Zealand) and University of Copenhagen (Denamrk)
Short-term visits at the University of Campinas (Brazil), University of Alberta (Canada), Max Planck Institute of Biochemistry (Germany)

His PhD project looks into individual metabolic response to diabetes treatments and investigate biomarkers that can be used to direct personalized treatment.

Dr Jin Xu is a Research Associate at King's College London. Her research focuses on the application of metabolomics and lipidomics to understand the underlying biology in Alzheimer's disease, together with the integration of multi-omics and clinical data to test early diagnostic panels.

Our research goal is to discover clinical tests for diagnostics and new disease treatments. We work on neuro and metabolic diseases and particulalrly in disease that affects the brain and the liver, like Alzheimer's Disease and Diabetes.

Our science is at the interface between chemistry and medicine and we are experts in biotechnology and the use of data science to allow the detection of thousands of small molecules / lipids in order to understand the underlying biology in disease.
We can get molecular data with mass spectrometry instruments and perform data analytics, including machine learning, to understand this biology. In order to translate results into the clinic we also work with clinical trials and evidence portfolios for EMA approval. This field of research can be called systems medicine, because it integrates -omic data and clinical data together to understand health.

Prenatal exposure to ethanol has long been associated with several long-term negative health consequences for the newborn including physical, cognitive, social, and behavioral impairments. The prevalence of FASD in North America may be as high as 5% of the population which represents an enormous public health concern (Flannigan, Coons-Harding, Anderson, Wolfson, Campbell, Mela, & Pei, 2020). Early identification of those affected is critical to address the special needs of these children to improve their outcomes. Outside of maternal self-report, there are limited strategies to objectively identify PAE at or near the time of birth.

Current testing strategies to detect prenatal exposure to ethanol is limited in scope and utility Unfortunately, a rapid immunoassay test does not exist leaving us with a very expensive and time-consuming liquid chromatography tandem mass spectrometry screening method. The objective of this presentation is to demonstrate a newly developed and validated a method for the detection of ethyl glucuronide in umbilical cord tissue using Laser Diode Thermal Desorption-Tandem Mass Spectrometry. The Laser Diode Thermal Desorption (LDTD), allows for a significant decrease in time and expense when compared to the current methodology.

The method was developed and validated according to the guidelines of the Scientific Working Group on Forensic Toxicology. Briefly, Umbilical Cord Tissue was weighed out (0.5 g), deuterated internal standard is added and homogenized in 3 mL of deionized water. Following centrifugation, the supernatant was purified using a solid phase extraction technique. The final reconstituted extract (8 µL) was transferred to an AD LazWell Plate and dried in a recirculating oven at 35°C until dry. The plate was transferred to the LDTD and analyzed. We will discuss our validation results as well as our experience with the analysis of authentic specimens in our laboratory.

Proteomics offers a wide collection of methodologies to study biological systems at the finest granularity. Faced with COVID-19, the most worrying pandemic in a century, a collective mass spectrometry effort was launched to study COVID?19 and propose alternative solutions for the detection of SARS-CoV-2. Since then, proteomics researchers have made significant progress in understanding how its causative virus SARS-CoV-2 hijacks the host's cellular machinery and multiplies exponentially, how the disease can be diagnosed, and how it develops, as well as its severity predicted. Numerous cellular targets of potential interest for the development of new antiviral drugs have been documented. The main findings gathered by our group and other proteomists will be discussed while pointing out how they could represent game?changers in the COVID-19 battlefield and in deciphering the long?term consequences of the infection.

Imaging mass spectrometry is a powerful technology that enables the visualization of biochemical processes directly in tissues by combining the molecular specificity of mass spectrometry with the spatial fidelity of microscopic imaging. Especially when studying lipids, there are many isobaric and isomeric molecules that complicate spectral analysis, with each isoform having a potentially unique cellular function. While traditional tandem mass spectrometry (MS/MS) approaches can distinguish amongst these compounds in select instances, this is often not the case. Our group is developing gas-phase reactions that afford the ability to provide improved molecular specificity without manipulating the sample. These gas-phase transformations are fast, efficient, and specific, making them ideally suited for implementation into imaging mass spectrometry workflows to enable novel structural identification and separation based on chemical reactivity. While traditional analytical analyses oftentimes simply use the mass spectrometer as a detector of molecular mass, we instead use the mass spectrometer as a reaction vessel to perform unique gas-phase transformations to provide unparalleled levels of chemical resolution.

Using the MrOS database and mass spectrometry, we demonstrate that 1,25(OH)2 Vitamin D, 24,25(OH)2 Vitamin D, and their associated metabolite ratios are associated with gut microbial diversity in older community dwelling men. Notably, 25(OH) Vitamin D levels did not show this association. We also demonstrate that firmicutes which frequently produce butyrate are associated with higher levels of activated Vitamin D. Overall, the project demonstrates that quantifying Vitamin D metabolites may provide more clinically relevant measures of Vitamin D metabolism.
