Background: Angiogenesis, the development of new blood vessels, is an important process in tissue development and wound healing, but becomes pathologic when associated with solid tumor growth, proliferative retinopathies, and rheumatoid arthritis. Accurate and reliable qualification of neovascular (angiogenic) response, both in vitro and in vivo, is an essential requirement for the study of new...

Background The aim of this study was the ex vivo expansion of Umbilical Cord Blood hematopoietic stem cells on biocompatible nanofiber scaffolds. Materials and Methods CD133+ hematopoietic stem cells were separated from umbilical cord blood using MidiMacs (positive selection) system by means of monocolonal antibody CD133 (microbeads) subsequently, flowcytometry method was done to asses...

In this paper, global uniform exponential stability of perturbed dynamical systems is studied by using Lyapunov techniques. The system presents a perturbation term which is bounded by an integrable function with the assumption that the nominal system is globally uniformly exponentially stable. Some examples in dimensional two are given to illustrate the applicability of the main results.

This study aimed to assess the quality of Persian translation of Orwell's (1949) Nineteen Eighty-Four by Balooch (2004) based on House's (1997) model of translation quality assessment. To do so, 23 pages (about 10 percent) of the source text were randomly selected. The profile of the source text register was produced and the genre was realized. The source text profile was compared to t...

in this paper, the chebyshev spectral collocation method(cscm) for one-dimensional linear hyperbolic telegraph equation is presented. chebyshev spectral collocation method have become very useful in providing highly accurate solutions to partial differential equations. a straightforward implementation of these methods involves the use of spectral differentiation matrices. firstly, we transform ...

In this letter, we established a traveling wave solution by using cosine function algorithm for Gardnerequation and (2+1)-dimensional breaking soliton system. The cosine method is used to obtain theexact solution.

In this paper, we investigate the existence of solution for a k-dimensional system of three points nabla fractional finite difference equations. Also, we present an example to illustrate our result.

in this paper we give conditions for a tuple of commutative bounded linear operators which holds in the property of the hypercyclicity criterion. we characterize topological transitivity and semi-hereiditarily of a dynamical system given  by an n-tuple of operators acting on a separable infinite dimensional banach space .
