We used in situ hybridization histochemistry to study the expression of the mRNA of the two vesicular monoamine transporters (VMAT1 and VMAT2) during embryonic and postnatal development of the central nervous system (CNS) int he rat. In the adult rat, VMAT2 mRNA is present exclusively in monoaminergic cell groups of the CNS and VMAT1 mRNA was reported to be present in the adrenal medulla and certa

In centers with access to high-end ultrasound machines and expert sonologists, ultrasound is used to detect metastases in regional lymph nodes from melanoma, breast cancer and vulvar cancer. There is, as yet, no international consensus on ultrasound assessment of lymph nodes in any disease or medical condition. The lack of standardized ultrasound nomenclature to describe lymph nodes makes it diffi

The search for significantly overrepresented and co-occurring transcription factor binding sites in the promoter regions of the most differentially expressed genes in microarray data sets could be a powerful approach for finding key regulators of complex biological processes. To test this concept, two previously published independent data sets on wounded human epidermis were re-analyzed. The prese

It is over three decades since a large terrestrial carbon sink (S-T) was first reported. The magnitude of the net sink is now relatively well known, and its importance for dampening atmospheric CO2 accumulation, and hence climate change, widely recognised. But the contributions of underlying processes are not well defined, particularly the role of emissions from land-use change (E-LUC) versus the

The “governing images” associated with the use and misuse of alcohol and drugs have varied across time and space. In Sweden, the 20th century saw a number of such perspectives – including the moral, the medical and the social – alternately dominating or coexisting. This multitude in perspectives is reflected in the organisation of addiction care and treatment, in which the responsibility for defin

Protein transport across the cytoplasmic membrane of bacterial cells is mediated by either the general secretion (Sec) system or the twin-arginine translocase (Tat). The Tat machinery exports folded and cofactor-containing proteins from the cytoplasm to the periplasm by using the transmembrane proton motive force as a source of energy. The Tat apparatus apparently senses the folded state of its pr

Soils are continuously exposed to cycles of drying and rewetting (D/RW), which drive pronounced fluctuations in soil carbon (C) fluxes. These C dynamics are characterized by a decoupled behavior between microbial biomass synthesis (growth) and CO2 production (respiration). In general, respiration rates peak shortly after RW and subsequently decrease, while the growth peaks lag several hours behind

Växelvis boende med en ungefärlig jämn uppdelning är vanligast förekommande i Skandinavien och har således mestadels studerats i denna kontext. Få studier har dock inriktat sig på yngre barn eller kvalitativt undersökt det växelvisa föräldra- och medföräldraskapet. Som en komponent i förståelsen av barnets tidiga anknytnings- och socioemotionella utvecklingsmiljö, fokuserar vi här på hur föräldrar

Current technological limitations make it impossible to store the enormous amount of data produced from proton-proton collisions by the ATLAS detector at CERN's Large Hadron Collider. Therefore, specialised hardware and software is being used to decide what data, or which proton-proton \textit{collision events}, to save and which to discard. A reduction in the storage size of each collision ev

I egenskap av lärarstudent med ett år kvar av utbildningen har jag fortfarande vissa svårigheter med att tolka den nya läroplanen, Lgr 11. Jag har därför undersökt hur yrkesaktiva lärare tolkar och hanterar den nya läroplanen. Studien innehåller också en analys av likvärdigheten av lärarnas tolkningar eftersom nya rapporter påpekar bristande likvärdighet i den svenska skolan. Studien är kvalitativAs a teacher student with only one year left until fully educated, I still have some difficulties completely understanding and interpreting the new curriculum, Lgr 11, for the higher grades of Swedish elementary school. Therefore I examined how working teachers tend to interpret and deal with this new curriculum. The thesis also contains an analysis of the teachers’ answers in the perspective of e

Populärvetenskaplig sammanfattning: Återfyllning av energibrunnar har tidigare inte varit aktuellt i någon större grad. De senaste åren har det höjts röster från ett fåtal kommuner om att installationen av dessa system kan skapa en potentiell föroreningsspridning. Trots att installationerna i verkligheten skapat få fall där problem uppstått, fortsätter vissa kommuner att sätta restriktioner mot öp

Numerous past studies investigating the performance of hedge funds suffer from two distinct problems: unreliable and biased return data inherent in virtually all databases and the use of static asset-pricing models. Using “indexes of indexes” for our hedge fund returns, both free of biases and highly representative, we investigate which risk factors investors are exposed to and whether hedge fund
