Nutritional Quality and Safety of the Spirulina Dietary Supplements Sold on the Slovenian Market.
Masten Rutar J, Jagodic Hudobivnik M, Nečemer M, Vogel Mikuš K, Arčon I, Ogrinc N. Masten Rutar J, et al. Foods. 2022 Mar 17;11(6):849. doi: 10.3390/foods11060849. Foods. 2022. PMID: 35327271 Free PMC article.
However, although iron contents were relatively high (7.64 to 316% of RDA), the actual bioavailability of iron was much lower since it was mainly present as the ferric cation. This study also confirms that pure Spirulina supplements are a good source of essential an …

Influence of iron redox state on black ripe olive processing.
García P, Romero C, Brenes M. García P, et al. J Sci Food Agric. 2018 Sep;98(12):4653-4658. doi: 10.1002/jsfa.8995. Epub 2018 Apr 10. J Sci Food Agric. 2018. PMID: 29528506
RESULTS: It was found that the penetration of the ferric cation into the olive flesh was an extremely slow process and it led to less-dark olives. Besides, at a pH higher than 6 the oxidation of the ferrous to the ferric cation was a very rapid reactio …

The folding equilibria of enterobactin enantiomers and their interaction with actinides.
Liu Z, Chai Z, Wang D. Liu Z, et al. Phys Chem Chem Phys. 2019 Jul 24;21(29):16017-16031. doi: 10.1039/c9cp01656b. Phys Chem Chem Phys. 2019. PMID: 31304940
Here, we report molecular dynamics simulations of both Ent enantiomers and their complexes with key actinides (Am3+, Cm3+, Th4+, U4+, Np4+ and Pu4+) to study the folding equilibria of Ent enantiomers and their binding affinity with actinides. For comparison, the ferric

Atomic scale modeling of iron-doped biphasic calcium phosphate bioceramics.
Gomes S, Kaur A, Grenèche JM, Nedelec JM, Renaudin G. Gomes S, et al. Acta Biomater. 2017 Mar 1;50:78-88. doi: 10.1016/j.actbio.2016.12.011. Epub 2016 Dec 10. Acta Biomater. 2017. PMID: 27965170
The present paper scrutinizes in detail the incorporation of ferric cation in order to correctly interpret the behavior of the iron-doped bioceramic in biological fluid. ...

Hippocampal gamma-aminobutyric acid transporter alterations following focal epileptogenesis induced in rat amygdala.
Ueda Y, Willmore LJ. Ueda Y, et al. Brain Res Bull. 2000 Jul 15;52(5):357-61. doi: 10.1016/s0361-9230(00)00272-0. Brain Res Bull. 2000. PMID: 10922514
To study the role of hippocampal gamma-aminobutyric acid (GABA) transporters in epileptogenesis, we induced chronic seizures by ferric cation injection into the rat amygdaloid body. We used western blotting to measure alterations in the expression of hippocampal GAB …

Implementation of Three Gallium-Based Complexes in the "Trojan Horse" Antibacterial Strategy against A. baumannii: A DFT Approach.
Kircheva N, Dobrev S, Nikolova V, Yocheva L, Angelova S, Dudev T. Kircheva N, et al. Inorg Chem. 2024 Aug 19;63(33):15409-15420. doi: 10.1021/acs.inorgchem.4c02411. Epub 2024 Aug 8. Inorg Chem. 2024. PMID: 39116415
By applying the powerful tools of the DFT approach, we aim to delineate those physicochemical characteristics that are of great importance for potentiating gallium's ability to compete with the native ferric cation for binding acinetobactin such as pH, solvent expos …

Predicting Silicate Glass Geochemistry Using Raman Spectroscopy and Supervised Machine Learning: Partial Least Square Applications to Amorphous Raman Spectra.
LaDouceur BO, McCanta M, Sharma B, Sarabia G, Dunn NE, Darby Dyar M. LaDouceur BO, et al. Appl Spectrosc. 2024 May;78(5):456-476. doi: 10.1177/00037028241234681. Epub 2024 Mar 5. Appl Spectrosc. 2024. PMID: 38439705
Raman band positional shifts are also mapped against underlying chemical variations; with major influences arising primarily as a function of overall oxidation state and silica concentration: via ferric cation (Fe(3+))/ferrous cation (Fe(2+)) ratios and SiO(2) (wt%) …

Flocculation of Chlamydomonas reinhardtii with Different Phenotypic Traits by Metal Cations and High pH.
Fan J, Zheng L, Bai Y, Saroussi S, Grossman AR. Fan J, et al. Front Plant Sci. 2017 Nov 20;8:1997. doi: 10.3389/fpls.2017.01997. eCollection 2017. Front Plant Sci. 2017. PMID: 29209355 Free PMC article.
Our results demonstrate that both wild-type and cell wall-deficient strains of the green unicellular alga Chlamydomonas reinhardtii efficiently flocculate (>90%) at an elevated pH of the medium (pH 11) upon the addition of divalent cations such as calcium and magnesium (>5 …
