Indian Contribution

Diaspora Theory has affected the literature of every language of the globe with its multiple characteristics. This literature is commonly referred to as Diasporic or Expatriate Literature. Diasporic Literature is a very broad idea and a paragliding term that involves all those literary works published by writers outside their home nation, but these works are linked to indigenous culture and background. All those authors can be considered as diasporic authors in this broad context, who write outside their nation but through their work stayed linked to their homeland. Diasporic literature has its origins in the sense of loss and alienation resulting from migration and expatriation. Diasporic literature generally deals with alienation, displacement, existential rootlessness, nostalgia, identity quest. Migrants suffer from the pain of being away from their homes, their motherland memories, the anguish of leaving behind everything familiar agonizes migrants ' minds. The diasporic Indians, too, are not breaking their ancestral land connection. There is a search for continuity and an astral impulse, an attempt to search for their origins. Settlement in alien territory leads to dislocation for them. Dislocation can be seen as a rupture with the ancient identity. By debating characteristics of expatriate or diasporic literature, the article tried to examine the reflection of Diaspora Theory and its multiple aspects in literature. The Indian contribution to diasporic literature was also evaluated in English.

AbstractIntermediate filament polypeptides (IFPs) are prominent components of cytoplasmic aggregates, which are pathognomonic for multiple diseases. Recent observations in cultured cells suggest that they are dynamic and subject to regulated turnover. The emerging concept is that multiple factors contribute to motility and turnover of IFP-containing aggregates. To understand their relative contribution, quantitative tools are needed. The current study addresses this need using epithelial cells producing mutant keratin IFPs that have been identified as the cause of the hereditary blister-forming skin disease epidermolysis bullosa simplex. Digital image analysis of individual granules allowed mapping of their complete life cycle, with information on multiple characteristics at any given time-point. The deduced signet features revealed rapid granule fusion and directed transport from the periphery towards the cell centre, and a limited, ~ 30 min lifetime with a slow, continuous growth phase followed by fast disassembly. As paradigmatic proof-of-principle, we demonstrate that inhibition of myosin II selectively reduces granule movement, linking keratin granule motility to retrograde cortical acto-myosin flow. The newly developed methods and established parameters will help in the characterization of known and the identification of novel regulators of IFP-containing aggregates.

Sustainable Product

This study examines sustainable tourism products in tourism destinations. Based on concepts of sustainable product design, our study proposes a framework for sustainable tourism products by adapting an existing Design for Sustainability Framework to consider and analyze the characteristics and themes of sustainable (tourism) products as well as their impact and scope. Using a pragmatic qualitative approach, 15 semi-structured interviews with destination managers from the German-speaking Alpine region formed the empirical basis of the study. The results emphasize key themes and multiple characteristics associated with sustainable tourism products in tourist destinations, addressing all sustainability components and design innovation levels. This study is the first to apply existing sustainable product design concepts to destination contexts and discuss their applicability for sustainable tourism products. For practitioners, this study provides support for the development of sustainable tourism products and contributes to a better understanding of the effects and levels of these products as well as sustainability marketing.

We detected intense CD56 immunostaining in the zona glomerulosa (ZG) and medulla of the normal human adrenal gland and therefore identified CD56, the neural cell adhesion molecule, as a membrane antigen specific for the ZG, aldosterone-producing adenoma (APA), and chromaffin cells. The APA and pheochromocytoma cells, which are histogenetically derived from the ZG and medulla, respectively, also showed intense CD56 immunostaining. Based on these findings we developed a strategy for isolating cells from the ZG and APA using CD56 immunobinding to magnetic beads. Morphology, gene expression studies, and aldosterone measurement confirmed that CD56 positive (+) cells were ZG and APA cells. Analysis of CD56+ cells under light and phase contrast microscopy evidenced that these cells formed clumps, as the ZG cells usually do; with electron microscopy they showed multiple features typical of a steroidogenic phenotype. Expression levels of the CD56 and the aldosterone synthase (CYP11B2) gene were markedly higher in CD56+ cells than CD56− cells (+1600 and +2100% increase, respectively). Moreover, aldosterone secretion was higher (+1380%) from CD56+ cells than from CD56− cells. Hence, this novel methodology allows isolation of a pure population of ZG and APA cells exhibiting multiple characteristics of the aldosterone-producing cells.
