Analysis of the distribution of adenosine and guanosine on fermented soybean cryosections by MALDI-MSI

Food Chemistry
Bioactive compounds in fermented soybeans (Natto) may reduce cardiovascular disease risk because of their relatively high concentration of vitamin K but may also increase purine levels, thereby increasing the risk of gout. To investigate purine distribution, we overcame the challenges associated with plant cryosection quality by using a conductive ...

Comparison of the Filamentous Fungi Library v4.0 MALDI Biotyper Platform vs MSI-2 performance for identifying filamentous fungi from liquid cultures

Journal of Clinical Microbiology
Correct, rapid, and reliable filamentous fungi identification is crucial for timely diagnosis and therapy. We compared the performance of the FFLv4.0 MALDI Biotyper and MSI-2 to identify filamentous fungi from clinical isolates.

A MALDI-MSI-based approach to characterize the spatial

Global warming and eutrophication of water bodies are driving the increase in cyanobacterial blooms, which produce toxins such as cylindrospermopsin (CYN). This compound has multiple toxic effects, and following CYN exposure, its distribution in the body varies, particularly in organs such as the liver and kidneys, suggesting its potential for ...

Imaging the distribution of agrochemicals in plants by MALDI-MSI. [PDF]

Pesticides are widely used in agriculture to control weeds, pests and diseases. Successful control is dependent on the compound reaching the target site within the organism after spray or soil application. This is influenced by a range of physiological and environmental factors.
