Ключевые слова (''Своб.индексиров.''): nanoparticles--ferrihydrite--magnetic properties--drug delivery
Аннотация: Nanoparticles of antiferromagnetically ordered materials acquire the uncompensated magnetic moment caused by defects and surface effects. A bright example of such a nano-antiferromagnet is nanoferrihydrite consisting of particles 2–5 nm in size, the magnetic moment of which amounts to hundreds of Bohr magnetons per particle. We present a brief review of the studies on magnetic properties of ferrihydrite produced by bacteria. Special attention is focused on the aspects of possible biomedical applications of this material, i.e., the particle elimination, toxicity, and possible use for targeted drug delivery.

Заглавие : Cross-singular dips in the NMR absorption line of polycrystals with isolated spin pairs
Место публикации : JETP Letters. - 1998. - Vol. 68, Is. 1. - P.101-106. - ISSN 0021-3640, DOI 10.1134/1.567828

Предметные рубрики: F-19 NMR
Аннотация: Cross-singular dips at the center of the spectra of polycrystals of Fake systems, i.e., systems containing well-isolated pair groupings, are obtained by numerical calculations of the NMR absorption line for a 10-spin (I=1/2) model. The physical reason for such dips is the behavior of the flip-flop component of the interpair dipole-dipole interactions ("6/5 factor"). Cases of experimental manifestation of cross-singular dips are noted. (C) 1998 American Institute of Physics.

Ключевые слова (''Своб.индексиров.''): magnetic nanoparticles--klebsiella oxytoca--magnetic resonance imaging--elimination
Аннотация: Suspension of magnetic nanoparticles (0.7 g/liter) obtained from Klebsiella oxytoca culture was injected intraperitoneally (1 ml), intramuscularly (in the hip; 100 mu l), and subcutaneously (200 mu l) or administered orally instead of drinking water for 2 days. The presence of magnetic nanoparticles was evaluated detected by MRI in 15 min and 2 h after injections and in 1 and 2 days after the beginning of oral consumption of the suspension. Magnetic nanoparticles were eliminated from the site of intramuscular and intraperitoneal injections and after oral consumption. The period of elimination after intramuscular and intraperitoneal injections did not exceed 2 h, while after oral consumption it corresponded to the time of gastrointestinal tract contents evacuation.

Ключевые слова (''Своб.индексиров.''): h-1 magnetic resonance microtomography--lima bean (phaseolus limensis) seeds--seed development and ripening--vascular bundles--transport of assimilates
Аннотация: H-1 magnetic resonance microtomography imaging was applied to study vascular systems in developing bean (Phaseolus limensis L.) seeds. Using the gradient echo method, we recorded 2D tomographic sections in the sagittal and axial planes of the fruits sampled from a vegetating plant on days 10, 17, 24, and 31 after fertilization. Any vascular connection between the tissues of maternal plant (bean pod and seed coat) and the embryo were undetectable. The embryo has an autonomous branched network of procambial strands in the cotyledons, converging to the embryonic axis. The bean pods are covered with a network of vascular bundles; large vascular strands run along the dorsal and ventral sutures. The seed coat vascular bundles are formed in the process of seed ripening and are represented by a developed vascular system multiply branching in the middle part of the ground parenchyma at the stage of physiological maturity. They are connected with the source of assimilates via the lateral pod veins and a large vascular bundle, entering the seed below the hilum via the placenta. Assimilates enter the external part of the seed coat, which contains no vascular bundles, via the funiculus vascular bundles and hilum tissue.

Ключевые слова (''Своб.индексиров.''): 1h micro-imaging--bean seed imbibition--lima beans--water distribution
Аннотация: Water uptake by dry Lima beans (Phaseolus limensis L.) was traced using 1H micro-magnetic resonance imaging. The studies are performed using two-dimensional longitudinal images. Channels through which water comes in an imbibing bean seed are determined; the water distribution inside the seed is shown to be heterogeneous. © 2016, Pleiades Publishing, Ltd.

Аннотация: Nuclear magnetic resonance (NMR) imaging results are presented for the comparative study of sedimentation of the polymethylmethacrylate colloidal suspensions with spherical particle diameters of 475, 350 and 255 nm. The time evolution of the particle volume fraction in the sedimenting system, velocity of the fluid/suspension interface, interface broadening, and sediment growth velocity are measured against the system concentration as well as the container geometry. Using the experimental data the hindered settling function is evaluated. The influence of the container geometry on the parameters defining the hindered settling function in different approaches is evaluated for the first time. The limiting value of the particle diameter is estimated at which the container geometry has no impact any longer. This effect can be explained by the microscale structure persisting at low Peclet numbers. In addition, the influence of the container geometry on interface broadening and sediment formation for different particle diameters and volume fractions is studied. Spontaneous sediment packing induced by a modified container geometry has been found. NMR imaging has proven to be a highly efficient research tool for studying sedimentation at low Peclet numbers.
