Background: Little is known about the causes of thyroid cancer, but insulin-like growth factor-I (IGF-I) might play an important role in its development due to its mitogenic and antiapoptotic properties. Methods: This study prospectively investigated the association between serum IGF-I concentrations and risk of differentiated thyroid carcinoma in a case-control study nested within the European Pr
This work studies osteoinduction and bone conduction in polyvinyl alcohol-tetraethylorthosilicate-alginate-calcium oxide (PTAC) biocomposite cryogels along with the synergistic effect of electrical stimulation. In vitro osteoinduction of C2C12 myoblast towards osteogenic lineage is demonstrated through alkaline phosphatase assay, scanning electron microscopy and energy dispersive X-ray spectroscop
Changes in vascular tone brought about by electrical field stimulation were studied in isolated guinea-pig and monkey pial arteries, using stimulus intensities similar to, or weaker than, those usually utilized by other investigators. In the guinea-pig, excitation of the smooth muscle cells was easily induced, even at low intensity stimulus parameters. This contraction faded upon repeated stimulat
The dissociation of DNA-cationic surfactant complexes with the addition of a negative amphiphile was studied by fluorescence microscopy (FM). The unfolding of DNA molecules previously compacted with cationic surfactant was shown to be dependent on the anionic surfactant chain length; lower amounts of a longer-chain surfactant were needed to release DNA into solution. However, we observed no depend
This paper examines a few of the fundamental principles in traditional and modern crisis analysis based on models of liquidity risk and moral hazard. The greatest emphasis in placed on moral hazard as it is concluded that this aspect was a central dilemma to the onset of the crisis in Thailand. The theory is analyzed through a Minskian fragility hypothesis and taken further with the Foley model as
The research area of climate field reconstructions has developed strongly during the past 20 years, motivated by the need to understand the complex dynamics of the earth system in a changing climate. Climate field reconstructions aim to build a consistent gridded climate reconstruction of different variables, often from a range of climate proxies, using either statistical tools or a climate model
Several lines of evidence suggest that a calcitonin-gene related peptide (CGRP) receptor antagonist may serve as a novel abortive migraine treatment. Here we present data on a human cell line and isolated human vessels for such an antagonist, BIBN4096BS. On SK-N-MC membranes, radiolabelled CGRP was displaced by both CGRP-(8-37) and BIBN4096BS, yielding pK(i) values of 8.5 and 11.4, respectively. F
A complex earth system model (atmosphere and ocean general circulation models, ocean biogeochemistry and terrestrial biosphere) was used to perform transient simulations of two interglacial sections (Eemian, 128-113 ky B. P., and Holocene, 9 ky B.P.-present). The changes in terrestrial carbon storage during these interglacials were studied with respect to changes in the earth's orbit. The effects
Planning for future needs has traditionally been considered to be restricted to human cognition. Although recent studies on great ape and corvid cognition challenge this belief, the phylogenesis of human planning remains largely unknown. The complex skill for future planning has not yet been satisfactorily established in any other extant primate species than our own. In humans, planning for future
In a forested near-urban location in central Germany, the CCN efficiency of particles smaller than 100 nm decreases significantly during periods of new particle formation. This results in an increase of average activation diameters, ranging from 5 to 8% at supersaturations of 0.33% and 0.74%, respectively. At the same time, the organic mass fraction in the sub-100-nm size range increases from appr
Nuclear activity in Iran has during last years been a widely discussed topic worldwide, as well as an important element in international relations. United States has looked for allies in attempts to isolate Iran politically and economically. India and Russia are powers of growing importance with interests in Iran. So far, both countries have cooperated with the US in IAEA although not completely f
This bachelor thesis main ambition is to develop a theoretical foundation that can provide plausible explanations to the relation between tourism and lack of political liberalization in less-developed and middle-income countries. The thesis identifies a number of unique features of tourism as a sociological and commercial phenomena. This conceptualization of tourism paves the way for the formulat
This BA-thesis examines whether realism can be empirically tested on the Iraq war in 2003. I am inspired by Mearsheimer's offensive realism, which holds that all states are aggressive because of the structure of international politics. Realism has a lot of theories about power, which I examine extensively and then apply empirically. Realism states that there are two strategies for a states? su
