Sequence analysis of the DRB1 promoter reveals limited polymorphism with no influence on gene expression.
2001
HLA-class II promoters contain a set of conserved regulatory regions necessary for constitutive and induced gene expression. For the HLA-DQB as well as for the DRB1 promoter sequence, polymorphisms with influence on gene expression have been reported. In contrast to these data we could show that there is very limited allele-specific polymorphism among the HLA-DRB1 promoter alleles. In a long range PCR we amplified a DNA sequence containing the promoter and the second exon of the DRB1 gene in one fragment. Nested PCR products of this PCR fragment for the promoter and for the second exon were analysed by DNA sequencing to allow the linkage of a promoter to its DR allele. Most investigated DRB…
Parathyroid hormone-related peptide and 8701-BC breast cancer cell growth and invasion in vitro: evidence for growth-inhibiting and invasion-promotin…
1995
It has been previously reported that 8701-BC cells, derived from a primary carcinoma of the breast, constitutively express parathyroid hormone-related peptide (PTHrP) gene and that N-terminal PTHrP immunoreactivity can be found in cell medium. Here we have firstly measured immunoreactive PTHrP in 8701-BC cell medium using antibodies raised against midregion and C-terminal fragments, and also demonstrated the expression of PTH/PTHrP receptor by 8701-BC cells. Secondly, we have examined the role, if any, elicited by diverse PTHrP domains on 8701-BC cell proliferation, and invasive behaviour in vitro related to production of extracellular proteolytic enzymes. Our data show that PTHrP [1-34], a…
MR-Tomographie versus CT-Arthrographie bei glenohumeralen Instabilitäten
1992
In a prospective study the diagnostic value of MRI compared to CT arthrography (CT-A) was evaluated in 26 patients with 27 instable shoulder joints. Surgical and/or arthroscopic correlation was available in all cases. Both methods showed a high accuracy (96% CT-A, 94% MRI) in the evaluation of the glenoid labrum. CT-A was significantly superior to MRI in the detection of capsular lesions (sensitivity 96% vs. 44%, accuracy 96% vs. 72%, negative predictive value 96% vs. 67%). CT-A and MRI results regarding humeral head fractures were similar; fractures of the glenoid rim were better detected by CT-A, the difference, however, was statistically not significant. Overall, CT-A proved to be superi…
Extracellular matrix regulation of PTHrP and PTH/PTHrP receptor in a human breast cancer cell line
1999
AbstractIt was previously reported that 8701-BC breast cancer cells express the gene for parathyroid hormone-related peptide (PTHrP) and its cognate receptor (PTHrP-R), and release immunoreactive PTHrP in the extracellular medium; it was also found that PTHrP, in turn, exerts a role on the proliferative and invasive behavior in vitro of the same cell line. On the other hand, evidence has been produced that adhesion of 8701-BC cells onto different collagen substrates influences in various ways a number of phenotypic expressions, such as cell growth, motility, invasion of reconstituted basement membrane and production of lytic enzymes of the extracellular matrix (ECM). In light of these previ…
MRI findings and evoked potentials in patients with myotonic dystrophy versus facioscapulohumeral dystrophy
1997
Evoked potentials recordings have been applied to many neurological disorders, localizing the lesions in the central nervous system (CNS) pathways. Facioscapulohumeral muscular dystrophy (FSHD) is a slowly progressive degenerative disease involving the muscles of the face and shoulders. On the contrary, myotonic distrophy (MD), the most frequent and severe myotonic disease, is caracterized by myotonia (delay of relaxation after voluntary contraction), muscular atrophy and dystrophic changes in non-muscular tissues. In the present investigation, patients with clinically and electromyographically verified FSHD and MD were examined using somatosensory evoked potentials (SEP) and brainstem aud…

Resumen tomado de la publicación El objetivo de este estudio es comprobar la efectividad de un programa basado en una metodología lúdico-narrativa para consolidar los contenidos y competencias matemáticas en Educación Infantil en comparación con otras metodologías utilizadas actualmente. Para ello, se seleccionaron 100 niños de 5-6 años que fueron divididos en tres condiciones experimentales: la metodología tradicional basada en fichas de trabajo (centros de interés); una metodología que incluye elementos visuoperceptivos de estimulación temprana y manipulativos, y una metodología que incluye componentes lúdicos y narrativos. Los instrumentos de evaluación utilizados han sido una prueba cri…
Perorāli ievadīta metformīna ietekme uz neiroiekaisumu un smadzeņu neironālo plasticitāti Alcheimera slimības tipa modeļa žurkās
2019
Alcheimera slimība (AD) ir pasaulē visbiežāk sastopamā neirodeģeneratīvā saslimšana, kā arī biežākais demences izraisītājs, turklāt šīs slimības izplatība ar katru gadu pieaug. Līdz šim izmantota simptomātiska terapija un kopš 2003. gada nav apstiprināts neviens jauns medikaments AD ārstēšanai, tādēļ arvien tiek meklēti jauni terapijas virzieni (Hung and Fu, 2017). Ņemot vērā, ka AD pacientu smadzenēs novērojami glikozes metabolisma traucējumi un paaugstināts cerebrālais glikozes līmenis (Campbell et al., 2017), mēs pārbaudījām antidiabētiskā preparāta metformīna devu (75 mg/kg un 100 mg/kg) ietekmi uz neiroieksumu un neironālo plasticitāti streptozocīna (STZ) izraisītāAD tipa modeļa žurkās…
Comprehensive analysis of interacting proteins and genome-wide location studies of the Sas3-dependent NuA3 histone acetyltransferase complex
2014
Highlights • We characterise Sas3p and Gcn5p active HAT complexes in WT and deleted TAP-strains. • We confirm that Pdp3p interacts with NuA3, histones and chromatin regulators. • Pdp3p MS-analysis reveals its phosphorylation, ubiquitination and methylation. • Sas3p can substitute Gcn5p in acetylation of histone H3K14 but not of H3K9. • Genome-wide profiling of Sas3p supports its involvement in transcriptional elongation.
Kansainvälinen aikuistutkimus arvioi väestön perustaitoja
2012
Investointi lukutaitoon hyödyttää paitsi yksittäisiä henkilöitä elämänlaadun ja ansiotason paranemisena, myös koko yhteiskuntaa terveydenhuollon, rikollisuuden ja sosiaaliturvan kustannusten vähenemisenä. Lukutaidon ohessa numerotaitoa ja ongelmaratkaisutaitoa voidaan pitää jopa perustavanlaatuisena ihmisoikeutena. Uusi kansainvälinen aikuistutkimus pyrkii mittaamaan näitä taitoja moniulotteisesti.
