introduction: extracellular matrix (ecm) components significantly influence the growth characteristics of cell, development of spontaneous contractile activity, andmorphologic differentiation. the present study evaluates the effect of ecm ongenotypic and physiologic characteristics of cardiomyocytes derived from embryonic stem (es) cells. material and methods: embryoid bodies derived from mouse...

We show that the initial value problem associated to the dispersive generalized Benjamin-Ono-Zakharov-Kuznetsov equation ut −D α xux + uxyy = uux, (t, x, y) ∈ R , 1 ≤ α ≤ 2, is locally well-posed in the spaces Es, s > 2 α − 3 4 , endowed with the norm ‖f‖Es = ‖〈|ξ| α + μ〉f̂‖L2(R2). As a consequence, we get the global wellposedness in the energy space E1/2 as soon as α > 8 5 . The proof is based ...

and Applied Analysis 3 A α , A β are matrices that will be updated adaptively with the following updating laws: ?̇? α (t) = −Q −1 ⋅ z ⋅ ξ T α ⋅ es, ?̇? β (t) = −Q −1 ⋅ z ⋅ ξ T β ⋅ es ⋅ u (t) (12) and finally the control law is described as follows: u (t) = 1 β (t) + β (x) (− [α (t) + ?̂? (x)] + v (t)) . (13) 2.2. Direct Adaptive Fuzzy Controller (DAFC). Control law u(t) in feedback linearization m...

Emilia sonchifolia L. (Asteraceae) is used in ethnomedicine for the treatment of a wide array of inflammatory disorders. This practice has also been supported by scientific reports which showed that extracts of E. sonchifolia possess anti-inflammatory effects in rodents. However, the mechanism(s) through which the extracts produce these effects is not known. In this study, the effect of a metha...

For a simple spherically symmetric mean-field dynamo model we investigate the possibility of determining the radial dependence of the coefficient α. Growth rates for different magnetic field modes are assumed to be known by measurement. An evolutionary strategy (ES) is used for the solution of the inverse problem. Numerically, we find quite different α-profiles giving nearly the same eigenvalue...

introduction: embryonic stem (es) cells are pluripotent cells that derived from inner cell mass (icm) of blastocyst stage and are able to differentiate in vitro into different cells. purpose: this study was initiated to evaluate the effect of basic fibroblast growth factor (bfgf) on differentiation of es cells into cardiomyocytes among with their response to cardiac drugs. methods: the mouse em...

introduction: stem cell biology has been the subject of much recent discussion. embryonic stem (es) cells, derived from the inner cell mass of the blastocyst stage of early mammalian embryos are expected to become a powerful tool in future regenerative medicine and developmental biology due to their capacity of self-renewal and pluripotency. in the present study, the ultrastructural development...

We engineered an acellular biomimetic microenvironment to regulate stem cell fate and applied it to maintain mouse embryonic stem (ES) cell self-renewal. In the 3D environment formed using hydrogel scaffolds in which specific integrin ligation was provided, Stat3 activation by exogenous leukemia inhibitory factor (LIF) no longer acted as a limiting factor for stem cell self-renewal. Instead, si...

Embryonic stem (ES) cells are pluripotent stem cells derived from the inner cell mass of the blastocyst. ES cell surface molecules are important for the identification, labeling, sorting, quality control and functional studies of ES cells. Currently, knowledge of ES surface molecules is limited. To identify new surface molecules, we generated a panel of rabbit monoclonal antibodies (rMabs) agai...
