in iran, the majority of vegetable oil producers , use pet for packaging their products . due to high solubility of pet oligomers in the oils , and shelf life of liquid oils , it is expected that some compounds migrate into the oil . this study was carried out to determine the amount of migration of terephtalates from pet bottles into sunflower oil and the effect of temperature and storage time...

Migration is the permanent movement of some people called migrant, from one place to another for some reasons and values. Their migration is determined by some values and goals that lead to changes in migrants’ interaction system. In human history the shape of migration was changed due to social and environmental changes. From the eve of 19 century migration became important social phenom...

Impairments in cell migration processes may cause various diseases, among which cancer cell metastasis, tumor angiogenesis, and the disability of immune cells to infiltrate into tumors are prominent ones. Mathematical modeling has been widely used to analyze the cell migration process. Cell migration is a complicated process and requires statistical methods such as random walk for proper analys...

Objective(s): To investigate the role of autophagy in advanced glycation end products (AGEs)-induced proliferation and migration in rat vascular smooth muscle cells (VSMCs).Materials and Methods: After culture, VSMCs were treated with 0, 1, 10, and 100 μg/ml concentrations of AGEs. Autophagy specific protein light chain 3 (LC3)-I/II was determined by western blotting, autophagosomes were observ...

objective(s): in order to grow cells in a three-dimensional (3d) microenvironment, self-assembling peptides, such as puramatrix, have emerged with potential to mimic the extracellular matrix. the aim of the present study was to investigate the influence of the self-assembling peptide on the morphology, survival, proliferation rate, migration potential, and differentiation of human meningioma st...

nomad’s livelihood is based on continuous migration between summer and winter pastures to obtain forage for their animals and access to contented weather. this living way has long history in iran which formed in accord with climate. in recent century, modernization has been caused many changes in traditional living way of nomads. therefore, nomads have no more their role and function as in th...

Oils extracted from plants have been used since ancient times and in many cultures .frying oils are used in many countries all around the world including Iran. Therefore it is of great importance to ensure the safety of these food products which are usually delivered in polyethylene terephthalate (PET) bottles. This study has investigated the effect of storage time and temperature on the migrat...

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...
