Manipulation of New Fluorescent Magnetic Nanoparticles with an Electromagnetic Needle, Allowed Determining the Viscosity of the Cytoplasm of M-HeLa Cells.

Magnetic nanoparticles (MNPs) have recently begun to be actively used in biomedicine applications, for example, for targeted drug delivery, in tissue engineering, and in magnetic resonance imaging. The study of the magnetic field effect on MNPs internalized into living cells is of particular importance since it allows a non-invasive influence on cellular activity. There is data stating the possibility to manipulate and control individual MNPs utilizing the local magnetic field gradient created by electromagnetic needles (EN).

Specific nanoarchitecture of silica nanoparticles codoped with the oppositely charged Mn and Ru complexes for dual paramagnetic-luminescent contrasting effects.

The silica nanoparticles (SNs) co-doped with paramagnetic ([Mn(HL)],) and luminescent ([Ru(dipy)]) complexes are represented. The specific distribution of [Mn(HL)] within the SNs allows to achieve about ten-fold enhancing in magnetic relaxivities in comparison with those of [Mn(HL)] in solutions. The leaching of [Mn(HL)] from the shell can be minimized through the co-doping of [Ru(dipy)] into the core of the SNs.

The Influence of Medium on Fluorescence Quenching of Colloidal Solutions of the Nd: LaF Nanoparticles Prepared with HTMW Treatment.

An original method was proposed to reduce the quenching of the NIR fluorescence of colloidal solutions of 0.1 at. % Nd: LaF nanoparticles (NPs) synthesized by aqueous co-precipitation method followed by hydrothermal microwave treatment.

Stable Aqueous Colloidal Solutions of Nd: LaF Nanoparticles, Promising for Luminescent Bioimaging in the Near-Infrared Spectral Range.

Two series of stable aqueous colloidal solutions of Nd: LaF single-phase well-crystallized nanoparticles (NPs), possessing a fluorcerite structure with different activator concentrations in each series, were synthesized. A hydrothermal method involving microwave-assisted heating (HTMW) in two Berghof speedwave devices equipped with one magnetron (type I) or two magnetrons (type II) was used. The average sizes of NPs are 15.

INFLUENCE OF A PSYCHOTYPE OF A PATIENT WITH MUSCULOSKELETAL DISORDER ON THE DEGREE OF WORK DISABILITY.

Musculoskeletal diseases significantly impair the quality of life and work limitation. Purpose: to determine specificities of work limitation dynamic amongst the patients with lower back and lower limbs musculoskeletal disorders grouped by their psychotypes within the outpatient physical therapy. The Work Limitations Questionnaire (WLQ) was used in the research.
