Ultrafast diffusion exchange nuclear magnetic resonance

open access: yesNature Communications, 2020
Analysis of exchange processes is time consuming by two-dimensional exchange NMR spectroscopy. Here the authors demonstrate a single-scan ultrafast Laplace NMR approach based on spatial encoding to measure molecular diffusion, with an increase by a ...

Design of a Quantitative LC-MS Method for Residual Toxins Adenylate Cyclase Toxin (ACT), Dermonecrotic Toxin (DNT) and Tracheal Cytotoxin (TCT) in Bordetella pertussis Vaccines

open access: yesToxins, 2021
The antigens for acellular pertussis vaccines are made up of protein components that are purified directly from Bordetella pertussis (B. pertussis) bacterial fermentation. As such, there are additional B.

Effects of n-3 fatty acids on the NMR profile of plasma lipoproteins.

open access: yesJournal of Lipid Research, 1996
The effects of fish oil supplementation (14.5 g n-3 fatty acids/day) on plasma lipoprotein particles in healthy volunteers were assessed by high resolution 13C and 1H nuclear magnetic resonance (NMR) spectroscopy.

Hyper-CEST NMR of metal organic polyhedral cages reveals hidden diastereomers with diverse guest exchange kinetics

open access: yesNature Communications, 2022
Self-assembling nanostructures that trap guest molecules find applications in materials research and the life sciences. Here, authors describe how ultra-sensitive NMR reveals sub-types with broken symmetry that significantly impacts guest exchange.

A study of low power laser on the regenerative process of Girardia tigrina (Girard,1850) (Turbellaria; Tricladida; Dugesiidae) Um estudo de laser de baixa potência no processo regenerativo de Girardia tigrina (Girard,1850) (Turbellaria; Tricladida; Dugesiidae)

open access: yesBrazilian Journal of Biology, 2009
The mechanism of regeneration does not start to restore the wound until its corresponding epimorphic phase. A bioestimulation of tissues and cells by laser radiation depends on the wavelength, on the dose, and on the intensity of the light.

Intracellular repair of oxidation-damaged α-synuclein fails to target C-terminal modification sites

open access: yesNature Communications, 2016
α-synuclein is a protein linked to the occurrence of Parkinson's disease. Here, the authors use time-resolved in-cell NMR spectroscopy to study the repair of methionine-oxidized α-synuclein by endogenous cellular enzymes.

Proton magnetic resonance studies of the aggregation of taurine-conjugated bile salts.

open access: yesJournal of Lipid Research, 1992
The concentration dependence of the 500 MHz 1H-NMR spectra of taurocholate, taurochenodeoxycholate, taurodeoxycholate, and the monosulfate esters of taurochenodeoxycholate has been examined at 0.154 M NaCl in D2O.
