Complex evolution of the DAL5 transporter family.

BACKGROUND: Genes continuously duplicate and the duplicated copies remain in the genome or get deleted. The DAL5 subfamily of transmembrane transporter genes has eight known members in S. cerevisiae. All are putative anion:cation symporters of vitamins (such as allantoate, nicotinate, panthotenate and biotin). The DAL5 subfamily is an old and important group since it is represented in both Basidio

Towards a Health Economic Simulation Model of Type 2 Diabetes in Sweden

The aim of this thesis was to provide part of the data required in updating/developing computer simulation models (CSMs) for type 2 diabetes mellitus (T2DM) using data obtained from routine clinical practice in Sweden. In paper I, evolution of five biomarkers (i.e., HbA1c, systolic blood pressure, BMI, LDL and total to HDL cholesterol ratio) over time was estimated using data on 5,043 newly diagn

A 2.7-6.1 GHz CMOS local oscillator based on frequency multiplication by 3/2

Frequency multiplication by 3/2 is proposed as a means to expand the frequency generation capabilities of a single LC VCO. Fractional frequency multiplication is obtained by cascading a broadband injection locked modulo-two divider and a multiply-by-three circuit based on edge combining. The proposed solution is inductorless, thus very compact. It allows the generation of all frequencies from 2.7

Oncostatin M acting via OSMR, augments the actions of IL-1 and TNF in synovial fibroblasts

OBJECTIVE: To identify how the gp130-signaling cytokine oncostatin M (OSM), acting alone or in concert with IL-1beta or TNFalpha, affects synovial fibroblast expression of genes relevant to inflammation and bone erosion in inflammatory arthritis. METHODS: Synovial fibroblasts (SFs) were isolated from non-arthritic wild type (WT) or OSM receptor deficient (OSMR(-/-)) mice and stimulated with OSM, I

Consumer perceptions and preferences on solid wood, wood-based panels, and composites: a repertory grid study

Knowledge about consumer perception and preferences on solid wood, wood-based panels, and wood-based composites is important for product development and marketing. The aim of this study was to identify attributes and associations that people use to describe different types of wood materials and to explore how they relate to preferences. The study involved nine samples that were evaluated with the

Non-Linear Portmanteau Tests

We derive Portmanteau tests for a large class of non-linear time series models. This is done by replacing the linear measure of dependence (correlation) with a more general concept. Asymptotic distributions for the test statistics are derived. The methodology is computationally inexpensive, yet more flexible than most similar tests. The tests are evaluated on two different sets of simulated data.

Consequences of immune system aging in nature: a study of immunosenescence costs in free-living Tree Swallows

Immunosenescence, the aging of the immune system, is well documented in humans and laboratory models and is known to increase infection risk, morbidity, and mortality among the old. Immunosenescence patterns have recently been unveiled in various free-living populations, but their consequences in the wild have not been explored. We investigated the consequences of immunosenescence in free-living T

Seasonal Trophic Niche Shift and Cascading Effect of a Generalist Predator Fish

Few studies have examined how foraging niche shift of a predator over time cascade down to local prey communities. Here we examine patterns of temporal foraging niche shifts of a generalist predator (yellow catfish, Pelteobagrus fulvidraco) and the abundance of prey communities in a subtropical lake. We predicted that the nature of these interactions would have implications for patterns in diet sh

Intra-governmental coordination for sustainable disaster recovery: A case-study of the Eden District Municipality, South Africa

Post-disaster coordination is an essential aspect to achieve sustainable disaster recovery. However, to date, little attention has been paid to the subject of coordination in disaster recovery in comparison to response coordination. This study is an investigation into the factors affecting coordination for sustainable disaster recovery. It uses the case-study of Eden district Municipality in South

Combined use of selective serotonin reuptake inhibitors and sedatives/hypnotics during pregnancy: risk of relatively severe congenital malformations or cardiac defects. A register study

Objectives: To investigate the proposed synergistic teratogenic effect of use of selective serotonin receptor inhibitors (SSRI) together with sedatives or hypnotics, primarily benzodiazepines, during pregnancy. Design: Cohort study of congenital malformations after maternal use of SSRI, sedatives/hypnotics or the combination of the two drug categories. Setting: Swedish national health registers. P

Prediction of Parasitic Components in an Automotive Environment

The amount of electrical loads and the complexity of the electric system in a vehicle is increasing at the same time as the allowed development time is decreasing. Possibilities to predict the electromagnetic behaviour is therefore of great importance. This paper addresses the problems of low frequency electromagnetic crosstalk between cables in a harness. Analytical expressions for estimation of

Mechanisms of Transgene Silencing in Neural Cells -Implications for Ex Vivo Gene Therapy to the Brain

Popular Abstract in Swedish Ett nytt och experimentellt sätt att bota eller lindra sjukdomssymptom är att, istället för att tillföra en medicin, rätta till felet på en genetisk nivå. Detta kan åstadkommas genom att överföra nya, fungerande gener, sk transgener, till celler som då börjar producera protein, som i sin tur kan ge upphov till en terapeutisk effekt. I hjärnan skulle denna typ av behandlThe use of genetically modifi ed neural stem and progenitor cells could possibly be a future strategy for repairing a brain suffering from neurodegeneration. However, so far it has proven diffi cult to maintain sufficient levels of a transferred gene in suitable cell types, after transplantation. In the present thesis I studied the silencing of transgenes induced upon differentiation of neural pro

Declarative-knowledge-based reconfiguration of automation systems using a blackboard architecture

This article describes results of the work on knowledge representation techniques chosen for use in the European project SIARAS (Skill-Based Inspection and Assembly for Reconfigurable Automation Systems). Its goal was to create intelligent support system for reconfiguration and adaptation of robot-based manufacturing cells. Declarative knowledge is represented first of all in an ontology expressed
