There are different views on the relationship between language and culture. Some consider them as separate entities one being a code-system and the other a system of beliefs and attitudes. Some believe in a cause and effect relationship between the two; and yet others argue for a co-evolutionary mode of interrelation. This paper will subscribe to the Hallidayan co-evolutionary view of the relat...
In this research, confront a myriad of problems understanding organizational culture. The various theories forwarded on this issue have only added to the complexity of the matter. In this article, the author defines organizational culture from a variety of viewpoints, arguing that organizational regulations are the reflection of the organizational culture. As such, an understanding of the organ...
Background and Objective: Various diseases and injuries can lead to loss cartilage tissue. Cartilage tissue engineering based on the use of stem cells which has provided a promising opportunity to repair damaged tissue. Recently, adipose-derived mesenchymal stem cells (ADSCs) have captured considerable scientific and clinic interest because of their easy access, rapid expansion in vitro...
Successful isolation, derivation and culturing of human pluripotent stem cells, including human embryonic stem cells (hESCs) and human induced pluripotent stem (hiPSCs) cells in laboratory scale has opened new horizones for cell therapy applications such as tissue engineering and regenerative medicine. However, most of the cell therapy protocols using these unique cells require large number of ...
allogeneic hematopoietic stem cell transplantation is used in the treatment of patients suffering from hematologic and non-hematologic disorders, but the application is limited by the identification of a suitable donor. umbilical cord blood (ucb) is an alternative source of hematopoietic stem cell (hsc) transplantation. despite all advantages, the limited cell dose is one of the major obstacle...
Purpose: Co-culture systems of marrow derived mesenchymal stem cells (mMSCs) with mature chondrocytes have theoretically been considered as a putative way of MSCs chondrogenic differentiation. MSCs differentiated in this system could be used for transplantation purpose without of any need to their purification since the cells with which MSCs are co cultured are native cartilage cells. Despite o...
compared to other methods of vaccine production, (e.g. culture flask and bioreactor system), the roller culture method for producing rabies vaccine is simpler, and the equipment easier to install and maintain, and also in the event of contamination of one roller, the entire batch need not be discarded. this system provides a much larger surface area than the culture flask, and also ensures a mu...

Background: One of the necessities of industrial societies is the application of developed measures/strategies for the prevention of occupational incidents in industrial companies. The present study was conducted with the aim of determining the role of the safety management system on safety culture of an oil and gas exploration and production company. Materials and Methods: This study was co...
