Chemical derivatization processes applied to amine determination in samples of different matrix composition.

open access: yesChemical Reviews, 2015
Amines are important biological compounds, and so their analysis and monitoring in various matrices is worthy of investigation and development.Due to the polar nature of amines, chromatographic analysis of free amines is generally unsatisfactory owing to

Cellular liquid biopsy provides unique chances for disease monitoring, preclinical model generation and therapy adjustment in rare salivary gland cancer patients

open access: yesMolecular Oncology, EarlyView.
We quantified and cultured circulating tumor cells (CTCs) of 62 patients with various cancer types and generated CTC‐derived tumoroid models from two salivary gland cancer patients. Cellular liquid biopsy‐derived information enabled molecular genetic assessment of systemic disease heterogeneity and functional testing for therapy selection in both ...

Carleman linearization approach for chemical kinetics integration toward quantum computation [PDF]

open access: yesarXiv, 2022
The Harrow, Hassidim, Lloyd (HHL) algorithm is a quantum algorithm expected to accelerate solving large-scale linear ordinary differential equations (ODEs). To apply the HHL to non-linear problems such as chemical reactions, the system must be linearized.

Deconvoluting interrelationships between concentrations and chemical shifts in urine provides a powerful analysis tool

open access: yesNature Communications, 2017
The NMR chemical shifts of a substance in a complex mixture strongly depend on the composition of the mixture itself, as many weak interactions occur that are hardly predictable. Chemical shift variability is the major obstacle to automatically assigning,

Characterization of the biofilm matrix composition of psychrotrophic, meat spoilage pseudomonads

open access: yesScientific Reports, 2020
Psychrotrophic Pseudomonas species are the key spoilage bacteria of aerobically stored chilled meat. These organisms readily form biofilms on meat under refrigerated conditions leading to consumer rejection and associated economic losses.

Combined spatially resolved metabolomics and spatial transcriptomics reveal the mechanism of RACK1‐mediated fatty acid synthesis

open access: yesMolecular Oncology, EarlyView.
The authors analyzed the spatial distributions of gene and metabolite profiles in cervical cancer through spatial transcriptomic and spatially resolved metabolomic techniques. Pivotal genes and metabolites within these cases were then identified and validated.

Extraction and Characterization of Sponge Gourd Outer Skin Fiber

open access: yesJournal of Natural Fibers, 2023
Plant-derived natural fibers have recently been used as a promising reinforcement in polymer matrix composites. Fibers from the inner sponge of the luffa cylindrica fruit have been the subject of several studies as reinforcement in various polymer resins.

Analysis of tissue specimens by matrix-assisted laser desorption/ionization imaging mass spectrometry in biological and clinical research.

open access: yesChemical Reviews, 2013
Human beings are adept at discerning relevant information from complex systems by processing visual information. Similarly, as scientists labor to understand the fundamental nature of complex biological systems, they have continued to rely on visual ...

Circulating tumor DNA (ctDNA) trajectories predict survival in trifluridine/tipiracil‐treated metastatic colorectal cancer patients

open access: yesMolecular Oncology, EarlyView.
The authors applied joint/mixed models that predict mortality of trifluridine/tipiracil‐treated metastatic colorectal cancer patients based on circulating tumor DNA (ctDNA) trajectories. Patients at high risk of death could be spared aggressive therapy with the prospect of a higher quality of life in their remaining lifetime, whereas patients with a ...
