Aqueous Dispersions of Unmodified Y@C₈₂ (C_2v ) Endohedral Metallofullerene

ChemistrySelect (2017)

Ivan V. Mikheev Ivan E. Kareev Vyacheslav P. Bubnov Dmitry S. Volkov М.В. Коробов

Aqueous dispersions of an unmodified (pristine) (AFD) nY@C82 (symmetry C2v) endofullerene were produced with a nearly 100% yield relative to the initial toluene solution of the endofullerene. To the best of our knowledge, this is the first report of this kind of endofullerene aqueous dispersions. The solvent-exchange ultrasound-assisted procedure requires no modification of the endofullerene surface or addition of any stabilizing agents into the aqueous phase. The procedure is applicable to any endohedral metallofullerene aqueous dispersions suitable for biomedical applications. The resulting dispersions are stable for at least 6 months. For the produced aqueous dispersions of Y@C82, the zeta potential of ca. –42 mV shows good stability; the average diameter of clusters was as small as ca. 120 nm. Techniques for purification and purity control of nY@C82 and of the intermediate toluene solution of Y@C82 were developed. The residual quantity of organic compounds was less than 1 ppb after the purification. Based on ICP–AES, headspace GC–MS, and MALDI–TOF, a procedure to assess endofullerene concentrations in the aqueous phase was proposed.

The Dynamics of Resting-State EEG and Salivary Trace Elements in Patients with Obsessive-Compulsive Disorder

ACS Chemical Neuroscience (2024)

Galina Portnova Guzal Khayrullina Ivan V. Mikheev Sofiya M. Byvsheva Elena V. Proskurnina

The study of salivary microelements and their neurophysiological and behavioral correlates in patients with obsessive-compulsive disorder (OCD) is a pressing issue in modern psychiatry, which, however, lacks adequate research at this time. In this study, we tested the dynamics of behavioral parameters, resting-state electroencephalogram (EEG), and salivary iron, copper, manganese, magnesium, and zinc in 30 healthy volunteers and 30 individuals with OCD before and after an emotional antisaccade task. The eye-movement data served as a measure of behavioral performance. Our research revealed consistently higher manganese concentrations in the OCD group compared to healthy volunteers associated with a higher EEG ratio of amplitude transformation and symptom severity. The dynamics of salivary microelements and resting-state EEG, possibly influenced by cognitive and emotional load during the anticsaccade task, differed between groups. In healthy volunteers, there was a decrease in salivary iron level with an increase in high-frequency power spectral density of EEG. The OCD group showed a decrease in salivary copper with an increased Hjorth mobility of EEG.

Albumin Retains Its Transport Function after Interaction with Cerium Dioxide Nanoparticles

ACS Biomaterials Science & Engineering (2023)

Madina M. Sozarukova Ekaterina M. Kochneva Elena V. Proskurnina Ivan V. Mikheev D. O. Novikov

The interaction of inorganic nanomaterials with biological fluids containing proteins can lead not only to the formation of a protein corona and thereby to a change in the biological activity of nanoparticles but also to a significant effect on the structural and functional properties of the biomolecules themselves. This work studied the interaction of nanoscale CeO2, the most versatile nanozyme, with human serum albumin (HSA). Fourier transform infrared spectroscopy, MALDI-TOF mass spectrometry, UV–vis spectroscopy, and fluorescence spectroscopy confirmed the formation of HSA-CeO2 nanoparticle conjugates. Changes in protein conformation, which depend on the concentration of both citrate-stabilized CeO2 nanoparticles and pristine CeO2 nanoparticles, did not affect albumin drug-binding sites and, accordingly, did not impair the HSA transport function. The results obtained shed light on the biological consequences of the CeO2 nanoparticles' entrance into the body, which should be taken into account when engineering nanobiomaterials to increase their efficiency and reduce the side effects.
