mucinous carcinoma of the breast is a well-differentiated type of adenocarcinoma accounting for 2-5% of all breast cancers. pure mucinous carcinoma of the breast has a favorable prognosis, usually seen in post-menopausal women. neuroendocrine differentiation has been described in both in-situ and infiltrating breast cancers .mucinous carcinomas of the breast appear to have the greatest associat...

ginger (zingiber officinale rosc.) is a herbaceous, rhizomatous, perennial, which its rhizomes are used as an important spices and medicine all over the world. the aromatic principles include zingiberine, while the pungent principles are known as gingeroles. callus culture of the plants can produce the same compounds exist on their parent plants. the aim of this work was to evaluate the effect ...

objective(s):sea cucumber derived bioactive compound is considered efficient in treatment of bone disorders. this study was performed   to evaluate the effect of this extract on differentiation of rat bone marrow mesenchymal stem cells (rbmmsc) into osteogenic lineage. materials and methods: isolated rbmmsc were grown in dmem supplemented with 10% fbs. the cells were exposed to different concen...

From a social systems theory perspective, globalisation can be conceptualised as an evolutionary social process. By fusing systems theories, evolutionary theories, and organisation theories, globalisation becomes apparent as a historical social process, which encompasses the emergence and reproduction of social systems such as firms or other organisations within the wider process of the globali...

The basis of this research project is the computer simulation of the emergence of ethnicity and cultural differentiation in prehistoric hunter-gatherer groups. Instead of working directly on a universal theoretical model, we have preferred a predictive simulation of a historical case (ancient Patagonia) where the knowledge about the simulated social system is available at the necessary level of...

Emerging sustainability challenges, such as food security, livelihood development and climate change, require innovative and experimental ways of linking science, policy and practice at all scales. This requires the development of processes that integrate diverse knowledge to generate adaptive development strategies into the future. Social learning is emerging as a promising way to make these l...

The purpose of this brief concluding chapter is to summarize our analysis by stages and to point up some implications for economic and sociological theory, respectively, and for the relations between them. Our central proposition is that economic theory is a special case of the general theory of social systems, which is in turn one of the main branches of the developing general theory of action...

We here review the evolutionary theory relevant to the question of human cooperation and compare the results to other theoretical perspectives. Then, we will summarize some of our own work, distilling a compound explanation that we believe gives a plausible account of human cooperation and selfishness. This account leans heavily on group selection on cultural variation but also includes lower l...

There is a large amount of interest in understanding users of social media in order to predict their behavior in this space. Despite this interest, user predictability in social media is not well-understood. To examine this question, we consider a network of fifteen thousand users on Twitter over a seven week period. We apply two contrasting modeling paradigms: computational mechanics and echo ...

background: in the field of cellular therapy, the impact of confluence degree on harvesting or differentiation of bmmscs and the effect of cell-to-cell contact remain controversial. therefore, the effect of confluence on properties of bmmscs was studied and efficiency of confluence-associated osteogenic differentiation was identified. materials and methods: the impact of 20, 50, 70, 80 and 100%...
