Peroxisomes import virtually all of their membrane and matrix proteins post-translationally. It is presently unknown whether, in mammalian cells, their exists a pool of mature peroxisomes which have received their complement of proteins and are import-incompetent. Previous work has shown that fibroblasts are capable of importing microinjected peroxisomal proteins into peroxisomes. This report d...

Nup358 (also known as RanBP2), a component of the cytoplasmic filaments of the nuclear pore complex, has been implicated in various nucleocytoplasmic transport pathways. Here, we identify Nup358 as an important factor for transportin-mediated nuclear import. Depletion of Nup358 resulted in a strong inhibition of nuclear import of the human immunodeficiency virus type 1 (HIV-1) Rev protein. HIV-...

This paper examines grandparents’ written accounts of conversations with their college-aged grandchildren. Using a thematic analysis, we describe 4 themes that indicate the place of the relationship in the grandparents’ lives and their general orientation to their grandchildren. It is argued that expressions of affiliation, pride, exchange (primarily of advice and information), and feeling dist...

1 School Children 2 3 4 5 6 7 Abstract 8 Next to available data about actual Internet use of young children at home, most research especially 9 focuses on the threats and opportunities about active Internet usage. Limited empirical research 10 focuses on the role and impact of parents in this context. In the present study, Internet parenting 11 styles are defined and operationalized to study th...

Leaving home is a key life event in the transition to adulthood, but it has been relatively less explored in demographic studies of contemporary Japan. This paper examines the relationship between home-leaving intensities of young adults and the rapid social, economic, and demographic changes that took place in post-World War II Japan. By using event-history analysis, the study focuses on 1) fa...

Rice comes second after wheat in Iran`s food consumption economy. However Iran is one of the greatest rice importer countries all over the world because of its rising population and recent growth in GDP. This paper presents an analysis of cointegration test between rice import and it`s economic factors over the period 1990-2011, employing Engle-Granger model. At first, Dickey-Fuller test shows ...

Mitochondria import most of their proteins from the cytosol. Dynamic protein complexes in the mitochondrial outer and inner membranes are responsible for the specific recognition and membrane translocation of preproteins. The preprotein translocase of the outer mitochondrial membrane contains several import receptors and a general import pore. The preprotein translocase of the inner membrane co...

In view of the importance of the meat imports and the exports of meat in Iran, this study focuses on the status of the global market of meat imports the unit price test in these markets between the years 1961 and 2011 using the market cointegration approach. The results of this study are indicative of prices co-integration in the international market of meat as well as among such major importer...
