Currently, it has been suggested that human mesenchymal stem cells (MSCs), a well-known multipotent cells, could modify the biological process in leukemia cells. Therefore, we evaluated MSCs’ possible effects on apoptosis and proliferation of acute lymphoblastic (ALL) MOLT-4 Accordingly, were co-cultured with MSCs. Then, 24, 48, 72 hours after treatment, percentages cell was estimated using flo...

In the ultimatum game, two players are asked to split a certain sum of money. The proposer has to make an offer. If the responder accepts the offer, the money will be shared accordingly. If the responder rejects the offer, both players receive nothing. The rational solution is for the proposer to offer the smallest possible share, and for the responder to accept it. Human players, in contrast, ...

introduction: recently, a novel gene was cloned and characterized named catsper, which codes for a unique ca2+ channel that is expressed excludively in the testis. it has crucial role in sperm motility, sperm penetration into the ovum and ultimately male fertility. in the present study, we have evaluated the expression of this gene at different ages of mouse by semi-quantitative rt-pcr. materia...

Introduction: Sialic acid plays pivotal roles in various critical physiological events at molecular and cellular levels and also pathological processes. Changes in sialic acid concentration are observed in many pathological processes; for example, there are some available data on the evaluated level of sialic acid and neurodegenerative prevalence. It can be proposed that sialic acid can play a ...

A partial differential equation (PDE) is a mathematical relation which involves functions of multiple variables and their partial derivatives. PDEs are used to formulate (and hence to aid in the solution of) problems involving functions of several variables, and they arise in a variety of important fields. For example, in physics, they are used to describe the propagation of sound or heat, elec...

background and purpose: skin cancer is one of the most common types of cancer. several studies suggest a high incidence of skin cancer in most countries. timp-2 is the tissue inhibitor of matrix metalloproteinase and exist in both cancer and normal cells. the aim of this study was to investigate the expression of timp-2 gene in patients with skin cancer and evaluating the association between th...

We study, analytically and numerically, the dynamical behavior of the solutions of the complex Ginzburg-Landau equation with diffraction but without diffusion, which governs the spatial evolution of the field in an active nonlinear laser cavity. Accordingly, the solutions are subject to periodic boundary conditions. The analysis reveals regions of stable stationary solutions in the model’s para...

Background: Pulegone (PGN) is a clear colorless oily liquid, which is widely used in different areas for flavoring foods, drinks, and dental products. There are several reports indicating that the metabolites of the PGN affect cytochrome-P450 family expression and activities. The cytochromes-P450 (cyp19) are involved in Leydig Cells aromatization. Therefore, present study was performed in order...

In this note, we investigated existence and uniqueness of entropy solution for triply nonlinear degenerate parabolic problem with zero-flux boundary condition. Accordingly to the case doubly hyperbolic equation, propose a generalization formulation prove result without any structure
