Molecular phylogeny of the extinct cave lion Panthera leo spelaea.

2004

To reconstruct the phylogenetic position of the extinct cave lion (Panthera leo spelaea), we sequenced 1 kb of the mitochondrial cytochrome b gene from two Pleistocene cave lion DNA samples (47 and 32 ky B.P.). Phylogenetic analysis shows that the ancient sequences form a clade that is most closely related to the extant lions from Africa and Asia; at the same time, cave lions appear to be highly distinct from their living relatives. Our data show that these cave lion sequences represent lineages that were isolated from lions in Africa and Asia since their dispersal over Europe about 600 ky B.P., as they are not found among our sample of extant populations. The cave lion lineages presented h…

TCDD induces c-jun expression via a novel Ah (dioxin) receptor-mediated p38–MAPK-dependent pathway

2005

The aryl hydrocarbon receptor (AhR) has a fundamental role during postnatal liver development and is essential for mediating dioxin toxicity. However, the genetic programs mediating, both, the toxic and physiological effects downstream of the transcription factor AhR are in major parts unknown. We have identified the proto-oncogene c-jun as a novel target gene of AhR. Induction of c-jun depends on activation of p38-mitogen-activated protein kinase (MAPK) by an AhR-dependent mechanism. None of the kinases that are known to phosphorylate p38-MAPK is activated by AhR. Neither the dephosphorylation rate of p38-MAPK is reduced. Furthermore, increased p38-MAPK phosphorylation in response to dioxi…

Induction of collagenase-3 (MMP-13) expression in human skin fibroblasts by three-dimensional collagen is mediated by p38 mitogen-activated protein k…

1999

Collagenase-3 (matrix metalloproteinase-13, MMP-13) is a recently identified human MMP with an exceptionally wide substrate specificity and restricted tissue-specific expression. Here we show that MMP-13 expression is induced in normal human skin fibroblasts cultured within three-dimensional collagen gel resulting in production and proteolytic activation of MMP-13. Induction of MMP-13 mRNAs by collagen gel was potently inhibited by blocking antibodies against alpha1 and alpha2 integrin subunits and augmented by activating antibody against beta1 integrin subunit, indicating that both alpha1 beta1 and alpha2 beta1 integrins mediate the MMP-13-inducing cellular signal generated by three-dimens…

Fysioterapeuters erfaringer med eldre deprimerte og bruk av fysisk aktivitet

2014

Masteroppgave i helsefag ME 518 Universitetet i Agder 2014 This article is based upon a study of the experiences of physiotherapists working with elderly depressed patients and the use of physical activity. Depression in the elderly is a common condition, and it is estimated to be the second most common cause of failing health towards 2020. According to litterature physical activity has a positive effect on depression in the elderly. The aim of this study was to investigate the experiences of physiotherapist`s in the treament of eldely depressed patients over 65 years of age. Data was collected by qualitative reasearch interviews of 5 physiotherapists. Important findings of this study were …

Gallium modulates osteoclastic bone resorption in vitro without affecting osteoblasts.

2010

Gallium (Ga) has been shown to be effective in the treatment of disorders associated with accelerated bone loss, including cancer-related hypercalcemia and Paget's disease. These clinical applications suggest that Ga could reduce bone resorption. However, few studies have studied the effects of Ga on osteoclastic resorption. Here, we have explored the effects of Ga on bone cells in vitro.In different osteoclastic models [osteoclasts isolated from long bones of neonatal rabbits (RBC), murine RAW 264.7 cells and human CD14-positive cells], we have performed resorption activity tests, staining for tartrate resistant acid phosphatase (TRAP), real-time polymerase chain reaction analysis, viabili…

An NMR Study of the Interaction of 15N-Labelled Bradykinin with an Antibody Mimic of the Bradykinin B2 Receptor

1997

An isotope-edited NMR study of the peptide hormone bradykinin (RPPGFSPFR) bound to the Fab fragment of a monoclonal antibody against bradykinin (MBK3) is reported. MBK3 was previously shown to provide a binding site model of the B2 bradykinin receptor [Haasemann, M., Buschko, J., Faussner, A., Roscher, A. A., Hoebeke, J., Burch, R. M. & Muller-Esterl, W. (1991) Anti-idiotypic antibodies bearing the internal image of a bradykinin epitope, J. Immunol. 147, 3882-3892]. Bradykinin was obtained in a uniformly 15N-labelled form using recombinant expression of a fusion protein consisting of the glutathione-binding domain of glutathione S-transferase fused to residues 354-375 of the high-molecular-…

Analysis of RET promoter CpG island methylation using methylation-specific PCR (MSP), pyrosequencing, and methylation-sensitive high-resolution melti…

2016

Background Already since the 1990s, promoter CpG island methylation markers have been considered promising diagnostic, prognostic, and predictive cancer biomarkers. However, so far, only a limited number of DNA methylation markers have been introduced into clinical practice. One reason why the vast majority of methylation markers do not translate into clinical applications is lack of independent validation of methylation markers, often caused by differences in methylation analysis techniques. We recently described RET promoter CpG island methylation as a potential prognostic marker in stage II colorectal cancer (CRC) patients of two independent series. Methods In the current study, we analy…

Introduction of an single nucleodite polymorphism-based “Major Y-chromosome haplogroup typing kit” suitable for predicting the geographical origin of…

2005

The European Consortium "High-throughput analysis of single nucleotide polymorphisms for the forensic identification of persons--SNPforID", has performed a selection of candidate Y-chromosome single nucleotide polymorphisms (SNPs) for making inferences on the geographic origin of an unknown sample. From more than 200 SNPs compiled in the phylogenetic tree published by the Y-Chromosome Consortium, and looking at the population studies previously published, a package of 29 SNPs has been selected for the identification of major population haplogroups. A "Major Y-chromosome haplogroup typing kit" has been developed, which allows the multiplex amplification of all 29 SNPs in a single reaction. A…

Genetic analysis of the short tandem repeat system D12S391 in the German and three Asian populations

1998

Abstract Genomic DNA samples from 222 individuals from Southern China, 154 individuals from Thailand, 100 individuals from Japan as well as from 124 German individuals were analysed for the short tandem repeat (STR) locus D12S391. Typing was carried out by polymerase chain reaction (PCR) amplification and subsequent polyacryramide gel electrophoresis and silver staining. In total, 12 alleles could be distinguished in two of the populations. Among Chinese, allele 19 is the most common with a frequency of 0.225, and among Germans, allele 18 with a frequency of 0.186. In the Thai population only 11 alleles could be distinguished and allele 19 is the most common with a frequency of 0.198. In Ja…
