objective(s):the mesenchymal stem cells (mscs) have been introduced as appropriate cells for tissue engineering and medical applications. some studies have shown that topography of materials especially physical surface characteristics and particles size could enhance adhesion and proliferation of osteoblasts. in the present research, we studied the distinction effect of 30 and 60 μg/ml of zinc ...

background: in the field of cellular therapy, the impact of confluence degree to harvest or differentiate bmmscs and the effect of cell-to-cell contact remains controversial. therefore, the effect of confluence on bmmscs properties was studied and confluence-associated osteogenic differentiation efficiency was identified. materials and methods: the impact of confluences at 20, 50, 70, 80 and 10...

BACKGROUND Abdominal aortic aneurysm (AAA) is a life-threatening disease and its prevalence rate increases with social aging. The degradation of elastic is an important factor in the formation of AAA. METHODS Adipose derived stem cells (ADSCs) and bone marrow mesenchymal stem cells (BMSCs) were isolated from rats, and identified by Oil red O and alizarin red staining after adipogenesis and os...

The article concerns with the prospects of using phenolphthalein test solution in practice surveying concrete and reinforced building structures planta. problem study is limits application on pH level determined (the indicator works only at 8≤rn≤10). There a need expanding application. In order to determine different zones we have modernize method by adding other indicators phenolphthalein. sta...

While few publications have documented the uptake of nanoparticles in plants, this is the first study describing uptake and distribution of the ultrasmall anatase TiO(2) in the plant model system Arabidopsis. We modified the nanoparticle surface with Alizarin red S and sucrose and demonstrated that nanoconjugates traversed cell walls, entered into plant cells, and accumulated in specific subcel...
