Preeclampsia (PE) is a pregnancy syndrome characterized by hypertension and organ damage manifesting after 20 gestational weeks. The etiology is of multifactorial origin, where placental stress causes increased levels of placenta-derived extracellular vesicles (STBEVs) in the maternal circulation, shown to cause inflammation, endothelial activation, vasoconstriction, and anti-angiogenic activity.

The Bicoid (Bcd) protein gradient is generally believed to be established in pre-blastoderm Drosophila embryos by the diffusion of Bcd protein after translation of maternal mRNA, which serves as a strictly localized source of Bcd at the anterior pole. However, we previously published evidence that the Bcd gradient is preceded by a bcd mRNA gradient. Here, we have revisited and extended this observ

It has been proposed that hyaluronan-binding proteoglycans play an important role as guiding cues during neural crest (NC) cell migration, but their precise function has not been elucidated. In this study, we examine the distribution, structure and putative role of the two major hyaluronan-binding proteoglycans, PG-M/versicans and aggrecan, during the course of avian NC development. PG-M/versicans

The BRCA1 gene is thought to exert its main function early in life. We, therefore, studied the effects of BRCA1 mutations on birth weight and birth length. This was carried out by comparing 33 women with and without mutations. Birth weight and length were obtained from a self-administered questionnaire. BRCA1 mutations carriers had a significantly lower birth weight (P = 0.0041) compared with non-

Protein Microchip Array technology makes it possible to examine patterns of protein expressions and modifications. Current technologies such as two-dimensional get electrophoresis (2-DE) in combination with mass spectrometry allows the identification of biologically relevant proteins with high resolving power, but has also considerable limitations. Most spots observed in 2-DE are from high abundan

Several studies have shown that alpha-ketoglutaric acid (AKG) increases serum levels of proline and has beneficial effects on skeletal development. We studied the effect of alpha-ketoglutaric (AKG) acid calcium salt (6 g AKG and 1,68 Ca/day) or calcium alone (1.68 Ca/day) on serum C-terminal cross-linked telopeptide of type I collagen (CTX) and osteocalcin (OC), as well as lumbar spine bone minera

Originally studied in relation to aging and cancer research, telomerase is now also investigated in relation to psychiatric disorders and treatments. Based on emerging clinical and preclinical data, we hypothesise that telomerase activation could represent a novel element mediating the mechanism of action of certain psychopharmacological interventions (e.g. antidepressants, lithium and antipsychot

Rapporten beskriver prototyper av kontinuerliga tvåfraktionsinsamlare för övervakning av partikulära luftföroreningar i arbetsmiljö som har konstruerats. En prototyp är personburen och ger möjligheter till insamling av två partikelstorleksfraktioner i 18 diskreta intervall. PIXE-metoden (analys med partikelinducerad röntgenstrålning) används för multielementanalys av de erhållna proven. Även med m

In the present thesis, the geographic distribution of variation within such species is investigated and discussed in relation to glacial survival and post-glacial migration, dispersal ability, breeding system and levels of gene-

Quantitative magnetic resonance imaging (MRI)-based biomarkers, which capture physiological and functional tumor processes, were evaluated as imaging surrogates of early tumor response following chemoradiotherapy in glioma patients. A multiparametric extension of a voxel-based analysis, referred as the parametric response map (PRM), was applied to quantitative MRI maps to test the predictive poten
