Mesenchymal stem cells modulate release of matrix proteins from tendon surfaces in vitro: a potential beneficial therapeutic effect

Aim: Injury of tendons contained within a synovial environment, such as joint, bursa or tendon sheath, frequently fails to heal and releases matrix proteins into the synovial fluid, driving inflammation. This study investigated the effectiveness of cells to seal tendon surfaces and provoke matrix synthesis as a possible effective injectable therapy. Materials & methods: Equine flexor tendon explants were cultured overnight in suspensions of bone marrow and synovium-derived mesenchymal stems cells and, as controls, two sources of fibroblasts, derived from tendon and skin, which adhered to the explants. Release of the most abundant tendon extracellular matrix proteins into the media was assayed, along with specific matrix proteins synthesis by real-time PCR. Results: Release of extracellular matrix proteins was influenced by the coating cell type. Fibroblasts from skin and tendon appeared less capable of preventing the release of matrix proteins than mesenchymal stems cells. Conclusion: The source of cell is an important consideration for cell therapy.

On the Electrochemical Deposition and Dissolution of Divalent Metal Ions

The deposition of Cu2+ and Zn2+ from aqueous solution has been investigated by a combination of classical molecular dynamics, density functional theory, and a theory developed by the authors. For both cases, the reaction proceeds through two one-electron steps. The monovalent ions can get close to the electrode surface without losing hydration energy, while the divalent ions, which have a stronger solvation sheath, cannot. The 4s orbital of Cu interacts strongly with the sp band and more weakly with the d band of the copper surface, while the Zn4s orbital couples only to the sp band of Zn. At the equilibrium potential for the overall reaction, the energy of the intermediate Cu+ ion is only a little higher than that of the divalent ion, so that the first electron transfer can occur in an outer-sphere mode. In contrast, the energy of the Zn+ ion lies too high for a simple outer-sphere reaction to be favorable; in accord with experimental data this suggests that this step is affected by anions.

Effect of bacillus thuringiensis on the biological parameters and phytophagy of podisus nigrispinus (hemiptera: pentatomidae)

The effect of Bacillus thuringiensis Berliner 1911 var aizawai strain GC-91 (Bta) on the biological parameters and phytophagy of Podisus nigrispinus (Dallas 1851) (Hemiptera: Pentatomidae) were evaluated using the follow treatments: a) provision of deionized water and prey Plutella xylostella (Linnaeus 1758) (Lepidoptera: Plutellidae); b) provision of only a solution containing Bta; and c) provision of prey and the solution containing Bta. To evaluate the phytophagy of the predator, leaves of Brassica oleraceae var acephala Linnaeus cv Manteiga da Georgia were provided and replaced every two days, and subsequently stained by immersion in 1% acid fuchsin. Staining enabled the visualization of the feeding sheath, which allowed for the quantification of punctures inflicted by P nigrispinus. The phytophagy, reproductive capacity and biological cycle in P nigrispinus were negatively affected by the presence of Bta; however, its predatory capacity was not altered.
