A selective uptake mechanism for some nucleosides and related substances was found in retinae of light adapted rabbits and fish. After the intravitreal injection in vivo of [(3)H]adenosine, [(3)H]inosine, [(3)H]guanosine and certain related compounds, the distribution of radioactivity was studied by autoradiography. Retinae were also incubated in [(3)H]adenosine and [(3)H]inosine and then were sim
1. The uptake of [3H] adenosine into specific populations of cells in the inner retina has been demonstrated. In mammalian retina, the exogenous adenosine that is transported into cells is phosphorylated, thereby maintaining a gradient for transport of the purine into the cell. 2. Endogenous stores of adenosine have been demonstrated by localization of cells that are labeled for adenosine-like imm
This paper addresses how the “I” of the praying individual is constructed in the interaction with the divinity in the praying of the Lord’s Prayer. This approach draws on social-constructive theory on identity formation and developmental psychology and a close reading of the Lord’s Prayer in Matthew 6 and the Sermon on the Mount. It is the assertion of this paper that a discourse analysis of the L
Urban green infrastructure (UGI) has been increasingly promoted as a key measure to mitigate heat stress in cities caused by the urban heat island effect and climate change impacts, including climate variability and extremes. However, comparable information concerning the performance of different UGI types to moderate such impacts is mostly lacking. This creates serious challenges for urban planne
Amongst migratory species, it is common to find individuals from different populations or geographical origins sharing staging or wintering areas. Given their differing life histories, ecological theory would predict that the different groups of individuals should exhibit some level of niche segregation. This has rarely been investigated because of the difficulty in assigning migrating individuals
The assembly of MHC class I molecules is regulated by a multi-protein complex in the endoplasmic reticules (ER) termed the loading complex. Tapasin is suggested to be one of the molecules forming this complex on the basis of its interaction with both the transporter associated with antigen processing (TAP) and MHC class I molecules. To address whether TAP is indispensable for the processing of the
Misfolding and aggregation of amyloid β (Aβ) are key features of Alzheimer's disease (AD) pathogenesis, but the molecular events controlling this process are not known in detail. In vivo, Aβ aggregation and plaque formation occur in the interstitial fluid of the brain extracellular matrix. This fluid communicates freely with cerebrospinal fluid (CSF). Here, we examined the effect of human CSF on A
Surfactants have been the basis for applications in several industrial sectors for a long time. However, fundamental research was 50 years ago still limited to a small number of academic groups and even basic aspects were controversial. The field has since undergone an enormous expansion and the improved understanding has laid the basis of numerous new products as well as been the basis of importa
Finite-element programs can be used for designing columns and their bracing systems. It is well known, however, that the output obtained from such programs is highly dependent upon the input (such as imperfections and stiffness properties). In the present study, the effects of imperfections on the predicted strength and stiffness requirements of steel columns and of their bracing systems are inves
The peroxisome proliferator-activated receptor gamma (PPARgamma), a member of the nuclear hormone receptor superfamily, is essential for adipocyte differentiation and glucose homeostasis. PPARgamma has been found recently to regulate macrophage activation in response to mitogens and inflammation. Our study shows PPARgamma to be preferentially expressed in the nuclei of resting T cells and to incre
In this study we have compared the interaction of human MHC class I molecules with IgG heavy chain (HC) binding protein (BiP), calnexin, calreticulin, tapasin and TAP in beta(2)-microglobulin (beta(2)m)- or TAP-deficient cells, as well as in wild-type B-LCL cells. Distinct differences between the association of HC and these endoplasmic reticulum (ER) proteins were found in the three cell lines. In
The growth hormone/insulin-like growth factor (IGF) axis can be manipulated in animal models to promote longevity, and IGF-related proteins including IGF-I and IGF-binding protein-3 (IGFBP-3) have also been implicated in risk of human diseases including cardiovascular diseases, diabetes, and cancer. Through genomewide association study of up to 30 884 adults of European ancestry from 21 studies, w

E-learning tools are becoming more advanced as Web 2.0 and the participatory Internet evolves. This paper discusses the need for a concrete pedagogical foundation on how to best use E-Learning tools. By examining some of the tools that are available now, we discuss what is suitable and what could be inappropriate. The significance of the traditional didactic triangle is reviewed and a new twist mi
