Manipulating the Hype: contemporary art's response to media cliches

Manipulating the Hype addresses art’s reaction to the barrage of signs produced by the media. The paper researches contemporary art’s response to clichéd media stereotypes and elucidates artists’ multifaceted perspective on overtly obvious yet widely embraced paradigms marketed by the media. Contemporary art’s strategic reconfiguration of media stereotypes is a valuable introspection upon the superficiality and impracticability of advertising and entertainment industry constructs. By reconsidering the mediated image, art has the ability to inspire reevaluation of cultural values. The thesis additionally attempts to ascertain the reinterpretation of media stereotypes as a common thread linking principal art movements and historically significant artworks from around the world since 1960. How does contemporary art respond to the extensive cultural influence of the media? Is a reaction to mass media a thematic commonality linking contemporary artists in the age of globalization? Manipulating the Hype is a dual outcome investigation comprised of written thesis and studio practice. The written thesis combines experience from a lengthy professional practice with historical and theoretical research. The visual thesis consists of twelve photographic works taken at on the Big Island of Hawaii. The images juxtapose artificial icons of power from popular culture with the natural force of the active lava flow. The process of research discloses how the advertising and entertainment industries capitalize upon innate human desires through the manipulative proliferation of archetypal imagery. Furthermore, the thesis establishes the widespread retort to media clichés as a palpable commonality in studio practices worldwide. The findings in the research make evident that although contemporary art does not have sufficient influence to reform the media, it can heighten public awareness of media tactics

Course of bone mass during and after hormonal replacement therapy with and without addition of nandrolone decanoate

A total of 33 women with postmenopausal osteoporosis were matched pairwise by age, years since menopause, and body mass index and randomized to receive either cyclic estrogen-progestagen replacement treatment (group 1) or the same treatment plus nandrolone decanoate (ND; group 2). Both groups were treated during 3 years and subsequently followed for another year off treatment. A year after cessation of the treatment the distal forearm bone mineral content in group 2 was significantly higher than that in group 1. Bone mass measurements in the axial skeleton already showed a significant difference in favor of group 2 after 3 years treatment, which persisted during the year off treatment. The decline in lumbar bone mineral mass and density in the 1 year off treatment was similar in both groups. Correction for body mass did not change these results. Bone turnover parameters did not show significant differences between the two groups after cessation of treatment. A higher muscle mass, induced by ND, could partly explain the differences between the groups since even 1 year after treatment was stopped an increased serum creatinine level was still observed in group 2

Role of calcium and cAMP in heterologous up-regulation of the 1,25-dihydroxyvitamin D3 receptor in an osteoblast cell line

To understand further the mechanism of action of parathyroid hormone (PTH) in the stimulation of the number of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) binding sites in UMR 106-01 cells we studied the role of cAMP and calcium. In addition to PTH other agents known to act via the cAMP signal pathway, prostaglandin E2, forskolin and dibutyryl cAMP, caused an increase in 1,25(OH)2D3 binding. Addition of the adenylate cyclase inhibitor 9-(tetrahydro-2-furyl)adenine resulted in a marked decrease of PTH-stimulated cAMP production but this was not followed by a reduction of 1,25(OH)2D3 receptor up-regulation by PTH. Increasing the intracellular calcium concentration by Bay K 8644 and A23817 independent of an activation of the cAMP signal pathway did not result in an increased 1,25(OH)2D3 binding. The calcium channel blockers nitrendipine and verapamil and chelating extracellular calcium with EGTA all reduced cAMP-mediated stimulation of 1,25(OH)2D3 binding. This reduction was not due to a reduced cAMP production as verapamil even potentiated PTH- and forskolin-stimulated cAMP production in a dose-dependent manner. The present study provides evidence for an interrelated action of calcium and cAMP in the heterologous up-regulation of the 1,25(OH)2D3 receptor. The current data show an interaction between the cAMP and calcium signal pathway at (1) the level of cAMP generation/degradation, and (2) a level located distal in the cascade leading to 1,25(OH)2D3 receptor up-regulation
