MetabolomicsHuman Archaeological Dentin as Source of Polar and Less Polar Metabolites for Untargeted Metabolomic Research: The Case of Yersinia pestis
Metabolomic approaches, such as in clinical applications of living individuals, have shown potential use for solving questions regarding the past when applied to archaeological material. Here, we study for the first time the potential of this Omic approach as applied to metabolites extracted from ar...

ProteomicsIn situ ribosome clustering and ultrastructure reorganization of polar tube proteins in germinated microsporidia polar tube
During host cell invasion, microsporidia translocate their entire cytoplasmic contents through a thin, hollow superstructure known as the polar tube. To achieve this, the polar tube transitions from a compact spring-like state inside the environmental spore to a long needle-like tube capable of long...

TranscriptomicsComparison of the human oocyte to its sister polar body
Clinicians need additional metrics for predicting quality of human oocytes for IVF procedures. Human polar bodies reflect the oocyte transcript profile. Quantitation of polar body mRNAs could allow for both oocyte ranking and embryo preferences in IVF applications. The transcriptome of a polar body ...

MetabolomicsSmall Polar Hits against S. aureus: Screening, Initial Hit Optimization, and Metabolomic Studies
The global prevalence of antibacterial resistance requires new antibacterial drugs with novel chemical scaffolds and modes of action. It is also vital to design compounds with optimal physicochemical properties to permeate the bacterial cell envelope. We described an approach of combining and integr...

MetabolomicsExamination of human osteoarchaeological remains as a feasible source of polar and apolar metabolites to study past conditions
Metabolomics is a modern tool that aids in our understanding of the molecular changes in organisms. Archaeological science is a branch of archaeology that explores different archaeological materials using modern analytical tools. Human osteoarchaeological material are a frequent finding in archaeolo...

MetabolomicsCharacterisation of monophasic solvent-based tissue extractions for detection of polar metabolites and lipids applying UHPLC-MS clinical metabolic phenotyping assays

Metabolic phenotyping of tissues uses metabolomics and lipidomics to measure the relative polar and non-polar (lipid) metabolite levels in biological samples. This approach aims to understand disease biochemistry and identify biochemical markers of disease. Sample preparation methods must be repr...
