Popular Abstract in Swedish I stort sett alla finrötter hos gran och många andra trädslag är koloniserade av ektomykorrhizasvampar (EM-svampar). Dessa lever i symbios med granen och utbyter mineralnäringsämnen mot sockerarter, som värdträdet bildat i fotosyntesen. EM-svamparna har visats överföra kalcium, kalium, kväve, magnesium och fosfor till sina värdträd. Den svenska skogen ingår i det boreaA method based on ingrowth mesh bags was developed to study the production of EMM. These bags were made of nylon mesh with a mesh size of 50 mu-m, which allows colonisation by fungal mycelia but excludes the tree roots. Using this method, the production of EMM was estimated in forest stands subjected to whole-tree harvesting (WTH) and in forest stands with different nutrient status regarding potas

The clitoris contributes to the normal female sexual response cycle. A significance of cyclic guanosine monophosphate (GMP) has been assumed in the control of clitoral vascular smooth muscle. As only a few investigations on the physiology of the vascular and non-vascular clitoral tissue have been carried out, knowledge on the mechanisms controlling this particular female genital organ is still vag

Unilateral lesions of nigrostriatal dopamine ( DA) pathways with 6-hydroxydopamine (6-OHDA) can be used to obtain a model of Parkinson's disease in the mouse. In the present study we examine two types of unilateral 6-OHDA lesions in the mouse for their ability to induce stable motor deficits and supersensitive molecular and behavioural response to L-DOPA.

Background: Previous work has demonstrated immunomodulatory, anti-tumor, anti-metastatic and anti-angiogenic effects of the small molecule quinoline-3-carboxamide tasquinimod in pre-clinical cancer models. To better understand the anti-tumor effects of tasquinimod in transplantable tumor models, we have evaluated the impact of the compound both on recruitment of myeloid cells to tumor tissue and o

This study documents conodont faunas of the Fezouata Formation, recovered from the AZ-1 borehole at Adrar Zouggar Mountain and from outcrops near Zagora in south-eastern Morocco. The Fezouata Formation was deposited on the peri-Gondwanan shelf near the South Pole during Early Ordovician times. It is composed of mostly fine-grained siliciclastics and is well known for including beds displaying the

A historical analysis of Christian revivalist movements in England, Wales, Scotland and North America illustrating points of convergence and divergence with the Korean Christian revival of 1907.

Many Streptococcus pyogenes immunoglobulin-binding proteins have structural similarities to the antiphagocytic M protein, including the well-known C repeats. One of these molecules is the immunoglobulin A-binding protein Arp, which is expressed by a serotype 4 strain for which no antiphagocytic M protein has yet been described. We expressed Arp4 in an S. pyogenes strain from which the structural g

Alveolar soft part sarcoma (ASPS) is an unusual tumor with highly characteristic histopathology and ultrastructure, controversial histogenesis, and enigmatic clinical behavior. Recent cytogenetic studies have identified a recurrent der(17) due to a non-reciprocal t(X;17)(p11.2;q25) in this sarcoma. To define the interval containing the Xp11.2 break, we first performed FISH on ASPS cases using YAC

The electron transfer process in the interaction of a slow highlycharged ion with a metal surface has been studied employing amicrocapillary foil as a target. The combination of the target and avisible light spectroscopy allows us to directly evaluate the initial(n,ℓ) distributions of the first transferred electrons. It wasfound that observed lines were primarily attributed to Δn=1transitions with

Activation of the beta-receptor for platelet-derived growth factor (PDGF) by its ligand leads to autophosphorylation on a number of tyrosine residues. Here we show that Tyr763 in the kinase insert region is a novel autophosphorylation site, which after phosphorylation binds the protein tyrosine phosphatase SHP-2. SHP-2 has also previously been shown to bind to phosphorylated Tyr1009 in the PDGF be

Efficient protein synthesis in bacteria requires initiation factor 2 (IF2), elongation factors Tu (EF-Tu) and G (EF-G), and release factor 3 (RF3), each of which catalyzes a major step of translation in a GTP-dependent fashion. Previous reports have suggested that recruitment of factors to the ribosome and subsequent GTP hydrolysis involve the dimeric protein L12, which forms a flexible "stalk" on

Denna uppsats berör solidaritet och rättvis ansvarsfördelning på asylområdet inom EU, principer som fastslås i artikel 80 i fördraget om Europeiska unionens funktionssätt. Solidaritetsprincipen är ämnad att genomsyra asyl-, immigrations- och gränspolitiken inom EU, men en definition eller innebörd av principen har aldrig fastslagits eller antagits. Trots detta har principen spelat stor roll som enThis thesis touches upon solidarity and the sharing of responsibility on asylum as enshrined in article 80 TFEU. The principle is purposed to govern all asylum, immigration and border check policies in the EU, but the actual meaning of the principle and what it entails has never been established. Nevertheless, the principle has been important as an underlying guiding principle in the development o

It seems as though every generation has been faced with crises that are presented as more dire than the last. The current elaborations of crises focus on peak oil, climate change and food production as imminent threats to the modes of production and consumption encompassed in the capitalist world system. The rise of flex crops – the industrial cultivation of select crops with corresponding technol

Sexual violence is a frequent problem in armed conflict. For twenty years, multiple measure have been adopted to stop this conduct but it is showing very little result. At the same time, there is a lively debate on several areas concerning sexual violence in armed conflict. This thesis analyses two of these areas of debate in order to find what the Community of States is doing wrong. Before enter

Abstract in UndeterminedThe dominant explanation for China's unprecendented rates of economic growth in the last three decades has regarded them as the consequence of the reform policies that, after Mao, the Chinese leaders embarked upon in 1978. The present study, in contrast, argues for continuity between the socialist period and the post-refrom era in China's economic course.Chinse socialism, i

In a country with a large historical and current share of emissions, recent climate inaction and political upheaval have disallowed substantial social-environmental reforms from being endorsed. This thesis critically examines the current cycle of contention in the United States by classifying the Sunrise Movement and the Democratic Socialists of America as social movement organizations through the

This thesis investigates the social position and political agency of women excombatants of the Farc-EP who laid down their arms after the 2016 peace agreement between the Colombian government and the Farc-EP. I show how, through the laying down of arms and reincorporation, women ex-combatants come to occupy a specific social position under historical and global power relations and intersecting for
