Objective(s): Extracellular matrix (ECM) is composed of many kinds of glycoproteins containing glycosaminoglycans (GAGs) moiety. The research was conducted based on the N-Acetylgalactosamine (GalNAc) degradation of ECM components by α-N-acetylgalactosaminidase (Nagalase) which facilitates migration and invasion of cancer cells. This study aims to investigate the effects of Naga-shRNA downregula...
Microfluidic devices have been widely used for cell migration research over the last two decades, owing to their attractive features in cellular microenvironment control and quantitative single-cell migration analysis. However, the majority of the microfluidic cell migration studies have focused on single cell types and have configured microenvironments that are greatly simplified compared with...
Objectives: To examine the extent to which an association exists between health of older parents and return migration of children in rural Thailand. Methods: Data come from the 2006 Migration Impact Survey specifically designed to obtain information on the impact of migration on older adults in rural areas. Associations are examined from both the perspectives of parents (N=883) and migrating ch...
migration and quality of redistribution of population across country is one of the main factors that planners take into account to control population and guide its movements to economic poles. scientific recognition of migration phenomenon is important for managing and policy making in the country. these movements change migration pattern, in a way that along with increase in population and the...
Extended abstract Introduction: Rural-urban migration is one of the common features of rural areas in developing countries including Iran. Metropolises as places of concentration of population, facilities, and services, have always been the main centers of absorbing rural-urban migrants. Migration is one of the main solutions of the poor and low-income rural households to increase income and a...
Population projection models that introduce uncertainty are a growing subset of projection models in general. In this paper, we focus on the importance of decisions made with regard to the model specifications adopted. We compare the forecasts and prediction intervals associated with four simple regional population projection models: an overall growth rate model, a component model with net migr...
Migration necessarily precedes environmental change in the form of deforestation and soil degradation in tropical agricultural frontiers. But what environmental factors may contribute to these migration streams in the first place? Identifying environmental characteristics related to this process is crucial for understanding how environmental change and migration may form recurrent feedback loop...
