embryonic stem cells are capable of differentiating to variety of cell tissues including cardiomyocytes. this developmental change is accompanied with a great deal of ion channel expression and functions. mouse stem cell derived cardiomyocytes were prepared and separated to yield isolated single cell suspension for cell current recording. in the present study some properties of the k + -current...

  Proteases play a key role in protein digestion in ticks and other haematophagous insects. Our understanding of blood meal digestion in digestive system of ticks can be very useful for better understanding of basic rules for control of ticks. Cells of the midgut endocytose blood components. Blood proteins uptake by midgut cells, suggesting the presence of proteases in the midgut cells. In this...

Objective(s): Umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  The objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. Materials and ...

background: amniotic membrane derived stem cells (amscs) have considerable advantages to use in regenerative medicine and their anti- inflammatory effects, growth factor secretion and differentiation potential make them suitable candidates for stem cell therapy of nervous system. the developing and neonatal brain contains a spectrum of growth factors to direct development of endogenous and dono...

objective: e-cadherin is a classic cadherin that plays a key role in epithelial cell adhesion. this protein is being referred to as the suppressor of proliferation and invasion. limited studies have investigated e-cadherin expression in salivary gland neoplasms. this study sought to assess the expression of e-cadherin and its possible role in progression and invasion of salivary gland neoplasms...

in this study, gas evolution in a vertical electrochemical cell is investigated numerically with a modified two-fluid model. the mathematical model involves solution of separate transport equation for the gas and liquid phases with an allowance to inter-phase transfer of mass and momentum. the governing equations are discreted via the finite volume technique and then are solved by the simple al...
