Electrochemical Reduction of LaO, NdO, and CeO in LiCl-LiO Melt.

The reduction of pellets composed of individual CeO, NdO and a LaO-NdO-CeO mixture by lithium extracted on a cathode during lithium chloride electrolysis at 650 °C was studied. The methods of cyclic voltammetry, electron microscopy, including determination of the elemental composition of the studied objects, and X-ray diffraction analysis were applied for the present study. The reduction degree of rare-earth metal (REM) oxides was determined using both the bromine method and reduction melting of the samples in the graphite crucible.

Investigation of the Quasi-Binary Phase Diagram FLiNaK-NdF.

The NdF solubility in molten eutectic FLiNaK, which is a conceivable medium for a molten salt reactor (MSR), was determined by the quasi-binary phase diagram FLiNaK-NdF. The eutectic mixture FLiNaK was prepared by direct melting of components LiF, NaF and KF·HF. The acidic anhydrous salt (KF·HF) was used instead of the hygroscopic KF.

Mast cells and aging.

Mast cells (MC) are present in the skin and mucous membranes, lymphoid organs, intestine wall and brain, where they are located close to the blood and lymphatic vessels and nerve terminals. As a source of a large number of biologically active substances, many of which are released quickly into the environment as a result of degranulation process, mast cells play an essential role in the regulation of physiological processes in the tissues where they are present. Changing the MC population and activity in the tissues during aging is associated with age-related changes of the skin and mucous membranes, the development of central nervous system disorders such as itching, headache, joint and muscle pain, memory loss, attention deficits, depression, anxiety and depressive disorders, autism, Alzheimer's disease and multiple sclerosis.

[A pH-dependent mechanism of energy transformation in joint fluid cells in osteoarthrosis of the knee joint and benefits of chondroitinsulfate].

Aim: To study bioenergetic processes in the synovial fluid (SF) in osteoarthrosis and to study relevant effects of chondroitinsulphate (structum).

Material And Methods: Changes in bioenergy parameters of SF were analysed in the course of 3-month structum treatment of 15 osteoarthrosis (OA) patients. Classic enzymatic tests and polarographic test of SF cells oxygen absorption rate were used.
