Differentiation of Brain Metastases due to Primary Malignancy and Glioblastomas using Dynamic Susceptibility Contrast-Enhanced MR at 3T

Purpose:To find out differences in cerebral blood volume (CBV) maps derived from dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSCE-MRI) in glioblastomas and cerebral metastases. The main purpose was to compare CBV maps between metastases with different primary malignancies. Furthermore the metastasis group was compared with the glioblastoma group.Method:Conventional imaging

Vitamin D In Older Women - Fractures, Frailty and Mortality

Vitamin D (25OHD) is essential for maintaining calcium homeostasis and inadequate levels have been associated with negative musculoskeletal as well as extraskeletal effects. Individuals at especially high risk of developing hypovitaminosis D are the elderly. The aim of this thesis was to investigate the association between 25OHD insufficiency (25OHD

Children diagnosed with HIV on antiretroviral therapy in Ethiopia:The family caregivers’ lived experience and treatment outcome

While the introduction of antiretroviral therapy has led to significant improvements in the survival of children living with HIV, several factors hamper its ultimate success in resource-limited settings. These factors include lack of proper management of the child’s treatment and follow-ups due to the existing fragile health and social systems and psychosocial and economic strains of family caregi

Jade har haft en central plads i den kinesiske verdensforståelse i årtusinder. For mange er jade nærmest synonymt med Kina. I ingen andre civilisationer har jade haft så bredspektret og historisk vedvarende brug og betydning som i Kina, og få materialer har fascineret kinesere i samme grad som jade.

Areal pressure in grammatical evolution : An Indo-European case study

Typological features can be expected to exhibit the same diachronic development multiple times during the history of a language family, exhibiting what is known variously as recurrence, homoplasy, or drift. This paper seeks to quantify the areal signal shown by recurrent mor- phosyntactic changes across the Indo-European language family. We use 108 morphosyntactic feature variants taken from the DThis article investigates the evolutionary and spatial dynamics of typological characters in 117 Indo-European languages. We partition types of change (i.e., gain or loss) for each variant according to whether they bring about a simplification in morphosyntactic patterns that must be learned, whether they are neutral (i.e., neither simplifying nor introducing complexity) or whether they introduce

A review of design guidance on wildland urban interface fires

Fires in the Wildland-Urban Interface (WUI) areas is a worldwide problem, which is gaining more importance over time due to climate change and constructions in the WUI areas. Standards and guidelines may greatly help the activities of planning, prevention and protection against wildfires. Some countries/States/local communities can already rely on existing standards and guidelines, while other are

Heterogenic Distribution of Aromatic L-Amino Acid Decarboxylase Neurons in the Rat Spinal Cord

Aromatic L-amino acid decarboxylase (AADC) is an essential enzyme in the synthesis of serotonin, dopamine, and certain trace amines and is present in a variety of organs including the brain and spinal cord. It is previously reported that in mammalian spinal cord AADC cells (called D-cells) were largely confined to a region around the central canal and that they do not produce monoamines. To date,

Reconstructing the origin of language families and variation

The chapter looks at language variation and change, and the relation of these processes to language reconstruction and classification. The chapter gives an overview of theories, models, methods, and data, describing how diversity and variation is modelled and measured for reconstruction and classification within traditional, comparative and statistical, evolutionary, or phylogenetic methods. First

Event Based Control

In spite of the success of traditional sampled-data theory in computer control it has some disadvantages particularly for distributed, asynchronous, and multi-rate system. Event based sampling is an alternative which is explored in this paper. A simple example illustrates the differences between periodic and event based sampling. The architecture of a general structure for event based control is p

Att äga framtiden : Perspektiv på kommunal utveckling

Centrum för kommunstrategiska studier (CKS) har i två decennier verkat som ett centrum för forskning och samverkan vid Linköpings universitet. CKS bedriver forskning med målet att fördjupa strategiskt relevant kunskap för en långsiktigt hållbar samhällsutveckling. Det gör vi genom akademiska fora och genom samverkan med kommuner och regioner. Genom det långsiktiga stödet från Linköpings universiteThe municipalities of Sweden are in motion. Some are growing strongly, while others shrink. The population's composition changes. The municipalities are becoming more different, which raises questions about structure and self-government. Climate and sustainability issues will be more central and how should the municipalities be governed in order to meet future demands for financial stability,democ
