Diffusion-weighted SPECIAL improves the detection of J-coupled metabolites at ultra-high magnetic field [PDF]

open access: yesMagnetic Resonance in Medicine 91 (2024) 4-18, 2023
A new sequence for single-voxel diffusion-weighted 1H MRS (DWS), named DW-SPECIAL, is proposed to improve the detection and subsequent estimation of the diffusion properties of strongly J-coupled metabolites. It combines the semi-adiabatic SPECIAL sequence with a stimulated echo (STE) diffusion block.

Diversity of Microbial Communities and Quantitative Chemodiversity in Layers of Marine Sediment Cores from a Causeway (Kaichu-Doro) in Okinawa Island, Japan

open access: yesFrontiers in Microbiology, 2017
Microbial community diversity and chemodiversity were investigated in marine sediments adjacent to the Okinawan “Kaichu-Doro” Causeway, which was constructed 46 years ago to connect a group of four islands (Henza-jima, Miyagi-jima, Ikei-jima, Hamahiga ...

Heterogeneous distribution of metabolites across plant species [PDF]

open access: yesPhysica A 388, 2771 (2009), 2009
We investigate the distribution of flavonoids, a major category of plant secondary metabolites, across species. Flavonoids are known to show high species specificity, and were once considered as chemical markers for understanding adaptive evolution and characterization of living organisms.

Fate of priority pharmaceuticals and their main metabolites and transformation products in microalgae-based wastewater treatment systems [PDF]

open access: yes, 2020
The present study evaluates the removal capacity of two high rate algae ponds (HRAPs) to eliminate 12 pharmaceuticals (PhACs) and 26 of their corresponding main metabolites and transformation products. The efficiency of these ponds, operating with and without primary treatment, was compared in order to study their capacity under the best performance ...

Antioxidant activity of plant secondary metabolites [PDF]

open access: yesArhiv za farmaciju, 2023
Oxidative stress can induce the development of many different disorders. Plant secondary metabolites may act as antioxidants by neutralisation of free radicals and by stimulation of endogenous antioxidant mechanisms.
