Effect of Thermal Processing on the Structural and Magnetic Properties of Epitaxial CoFeGe Films.

The structure and magnetic properties of epitaxial Heusler alloy films (CoFeGe) deposited on MgO (100) substrates were investigated. Films of 60 nm thickness were prepared by magnetron co-sputtering at different substrate temperatures (T), and those deposited at room temperature were later annealed at various temperatures (T). X-ray diffraction confirmed (001) [110] CoFeGe || (001) [100] MgO epitaxial growth.

Control of Structural and Magnetic Properties of Polycrystalline CoFeGe Films via Deposition and Annealing Temperatures.

Thin polycrystalline CoFeGe films with composition close to stoichiometry have been fabricated using magnetron co-sputtering technique. Effects of substrate temperature (T) and post-deposition annealing (T) on structure, static and dynamic magnetic properties were systematically studied. It is shown that elevated T (T) promote formation of ordered L2 crystal structure.

The influence of probiotic diet and chondroitin sulfate administration on Ptgs2, Tgfb1 and Col2a1 expression in rat knee cartilage during monoiodoacetate-induced osteoarthritis.

Background: Osteoarthritis (OA) is a common worldwide disease induced by a wide range of biochemical processes, mainly inflammation and degradation of collagen. The aim of this study, was to describe the effect of a multistrain probiotic (PB) and chondroitin sulfate (CS), administered separately or in combination, on the expression of Ptgs2, Tgfb1 and Col2a1 during monoiodoacetate-induced OA in male rats.

Methods: OA was induced in male rats by injecting monoiodoacetate in right hind knee.

Effect of Chondroitin Sulfate on Blood Serum Cytokine Profile during Carrageenan-induced Edema and Monoiodoacetate-induced Osteoarthritis in Rats.

Background: Blood cytokines affect the development of inflammatory processes in both normal and pathological states. We have studied changes in the concentration of interleukins (ILs) - 1β, IL-4, IL-10, IL-12B p40, transforming growth factor β (TGF β), tumor necrosis factor (TNF-α) in acute carrageenan-induced inflammation and degenerative-dystrophic changes of knee joint caused by monoiodoacetate-induced Osteoarthritis (OA) in experimental models on rats. We also investigated the change in the cytokine profile during prophylactic and therapeutic administration of chondroitin sulfate to animals under experimental conditions.
