Background: Most studies of brain structure and function, and their relationships to cognitive ability, have relied on inter-individual variability in magnetic resonance (MR) images. Intra-individual variability is often ignored or implicitly assumed to be equivalent to the former. Testing this assumption empirically by collecting enough data on single individuals is cumbersome and costly. We coll

Holst-Ekströms bidrag är en essä som handlar om ett antal franska slott, från 1700 och 1800-talen, om minnets roll i förhållande till arkitekturen och litteraturen. Den behandlar också konstnären Marie Anderssons specifika relation till fotografi och arkitektur.This essay is about a number of French castles, from the 18th and 19th centuries, it concerns the rôle of architecture in relation to memory and litterature. It is also about the specific works of artist Marie Andersson, and how she photography and architecture.

Essän om konstnären Anders Stolts skulpturala verk Stilleben sätter in arbetena i konsthistoriska, teoretiska, arkeologiska och haptiska perspektiv.This essay on the sculptural works of Anders Stolt puts the works in different contexts: art historical, theoretical, aeaeological, and haptic.

In prokaryotes, several mRNA sequences surrounding the initiation codon have been found to influence the translation process; these include the downstream region and its codon context, the Shine-Dalgarno sequence and the S1 ribosomal protein-binding site. In this thesis, the purpose has been to study the role of the downstream region and Shine-Dalgarno-like sequences on early translation elongatio

Essän handlar om trädgårdsstaden Tungelsta, idén om eremitens hydda, trädgården och platsen.

Muscarinic acetylcholine receptors (mAChRs) play a central role in the mammalian nervous system. These receptors are G protein-coupled receptors (GPCRs), which are activated by the agonists acetylcholine and muscarine, and blocked by a variety of antagonists. Mammals have five mAChRs (m1-m5). In this study, we cloned two structurally related GPCRs from the fruit fly Drosophila melanogaster, which,

Rrp6 is an exoribonuclease involved in the quality control of mRNA biogenesis. We have analyzed the association of Rrp6 with the Balbiani ring pre-mRNPs of Chironomus tentans to obtain insight into the role of Rrp6 in splicing surveillance. Rrp6 is recruited to transcribed genes and its distribution along the genes does not correlate with the positions of exons and introns. In the nucleoplasm, Rrp

One year ago, we discovered a new family of insect RYamide neuropeptides, which has the C-terminal consensus sequence FFXXXRYamide, and which is widely occurring in most insects, including the fruitfly Drosophila melanogaster and the red flour beetle Tribolium castaneum (F. Hauser et al., J. Proteome Res. 9 (2010) 5296-5310). Here, we identify a Drosophila G-protein-coupled receptor (GPCR) coded f

BACKGROUND: Salmonella enterica serotype Enteritidis (SE) is considered to be one of the most potent pathogenic Salmonella serotypes causing food-borne disease in humans. Since a live bacterial vaccine based on surface display of antigens has many advantages over traditional vaccines, we have studied the surface display of the SE antigenic proteins, H:gm and SefA in Escherichia coli by the β-autot

5-Fluorouracil (5FU) is a fluoropyrimidine used for the treatment of solid tumors. 5FU is a precursor of dTTP and UTP during biogenesis, and it interferes with both DNA and RNA metabolism. The RNA exosome, a multisubunit complex with ribonucleolytic activity, has been identified as one of the targets of 5FU in yeast. Studies in human cells have shown that the catalytic subunit of the nuclear exoso

Expression of minigenes encoding tetra- or pentapeptides MXLX or MXLXV (E peptides), where X is a nonpolar amino acid, renders cells erythromycin resistant whereas expression of minigenes encoding tripeptide MXL does not. By using a 3A' reporter gene system beginning with an E-peptide-encoding sequence, we asked whether the codons UGG and GGG, which are known to promote peptidyl-tRNA drop-off at e

Eukaryotic cells have evolved quality control mechanisms to degrade aberrant mRNA molecules and prevent the synthesis of defective proteins that could be deleterious for the cell. The exosome, a protein complex with ribonuclease activity, is a key player in quality control. An early quality checkpoint takes place cotranscriptionally but little is known about the molecular mechanisms by which the e

The Shine-Dalgarno (SD+: 5'-AAGGAGG-3') sequence anchors the mRNA by base pairing to the 16S rRNA in the small ribosomal subunit during translation initiation. We have here compared how an SD+ sequence influences gene expression, if located upstream or downstream of an initiation codon. The positive effect of an upstream SD+ is confirmed. A downstream SD+ gives decreased gene expression. This effe

In Escherichia coli the codons CGG, AGG, UGG or GGG (NGG codons) but not GGN or GNG (where N is non-G) are associated with low expression of a reporter gene, if located at positions +2 to +5. Induction of a lacZ reporter gene with any one of the NGG codons at position +2 to +5 does not influence growth of a normal strain, but growth of a strain with a defective peptidyl-tRNA hydrolase (Pth) enzyme

The influences on gene expression by codons at positions +2, +3, +5 and +7 downstream of the initiation codon have been compared. Most of the +2 codons that are known to give low gene expression are associated with a higher expression if placed at the later positions. The NGG codons AGG, CGG, UGG and GGG, but not GGN or GNG (where N is non-G), are unique since they are associated with a very low g

The 1970s is a paradoxical decade. On the one hand, it marked the gradual demise of the industrial society and the end of the «Golden Age» of capitalism. On the other hand, the decade saw the renaissance of international banking and finance after almost half a century of retreat, thanks to the explosive growth of the Eurodollar market. International banking, which had remained dormant since the 19

European Banks and the Rise of International Finance examines the historical origins of the financialised world we live in by analysing the transformations in world finance which occurred in the decade from the first oil crisis of 1973, until the debt crisis of 1982. This a crucial and formative decade for understanding the modern financial landscape, but it is still mostly unexplored in economic

This chapter deals with the performance of commercial and financial services in Europe. Companies in both sectors have undergone considerable concentration in all analysed countries, but those from Great Britain, Germany, and France emerged as the largest companies in Europe from the early twentieth century onwards. Most impressive, however, has been the expansion of the size and business of banks
