Risk factors for suicidal behaviour include adverse life events as well as biochemical parameters acting, e.g. within the hypothalamic-pituitary-adrenal axis and/or monoaminergic systems. The aim of the present investigation was to study stressful life events and biological stress markers among former psychiatric inpatients, who were followed up 12 years after an index suicide attempt. At the time
Enterohemorrhagic Escherichia coli (EHEC) infection leads to marked intestinal injury. Sigmoid colon obtained from two children during EHEC infection exhibited abundant TUNEL-positive cells. To define which bacterial virulence factors contribute to intestinal injury the presence of Shiga toxin-2 (Stx2), intimin and the type III secretion system were correlated with symptoms and intestinal damage.
Consumer awareness regarding food production and food content is steadily growing. An alternative to the current model of global food chains is local production of food and local sales of food at farmers’ markets. This chapter assesses the social and economic benefits of farmers’ markets both for the farmers taking part in the markets and for the consumers purchasing the products on sale. The deve
The article uses conceptual metaphor theory in order to analyse how the concept of “copy” in copyright law is expanding in a digital society to cover more phenomena than it originally did. For this purpose, the legally accepted model for valuing media files in the case against The Pirate Bay (TPB) is used in the analysis. When four men behind TPB was convicted in District Court of Stockholm, Swede
To evaluate the influence of hard exudates on macular function in patients with diabetic retinopathy. METHODS: Thirty seven eyes from 27 diabetic patients, aged 57 +/- 14 years, diabetes duration 12.5 +/- 9 years, not previously treated with photocoagulation, underwent fundus photography, multifocal electroretinography (mfERG) and optical coherence tomography (OCT). Hard exudates were graded from
A central question in Alzheimer's disease (AD) research is what role β-amyloid peptide (Aβ) plays in synaptic dysfunction. Synaptic activity increases Aβ secretion, potentially inhibiting synapses, but also decreases intraneuronal Aβ, protecting synapses. We now show that levels of secreted Aβ fall with time in culture in neurons of AD-transgenic mice, but not wild-type mice. Moreover, the ability
Övergödningen är ett av de största hoten mot Östersjöns miljö. Den orsakar inte bara algblomning under sommarhalvåret utan även syrebrist (hypoxi). Utbredningen av syrefria bottnar i Östersjön har ökat fyrfaldigt sedan 1960-talet till följd av ökade utsläpp av näringsämnen, så som fosfor och kväve. Undersökningar av långa sedimentkärnor i Östersjön visar dock att dagens syrebrist inte är unik utanThe Baltic Sea is suffering from bad ecosystem health due to strong impacts of anthropogenic activities. Since 1960, the hypoxic (< 2mg/l dissolved oxygen) area has expanded to c. 49 000 km2, resulting in an amplified eutrophication, which severely threats the ecosystem of the Baltic Sea. The long-term trend in basin-wide hypoxia in the Baltic Sea is not fully understood. This study explores the t
In the field of second language acquisition (SLA) it is an important question, which role the native language assumes in the acquisition of another language. Studies have shown that there exists a native language influence on a phonological and lexical level. The situation in syntax is however different. Here a native language influence (transfer) is not self-evident.
Uppsatsen undersöker den skönlitterära läsupplevelsen i applikationen Iceberg Reader för Iphone. Vid uppsatsens tillkomst var läsapplikationer för Iphone och Ipad något nylanserat i Sverige, och få läsare hade erfarenhet av läsning via denna plattform. Med hjälp av två kvalitativa undersökningar – en enkät, där nio personer deltog, och en fokusgruppsundersökning, där fem av de nio var med – har vi
