Vetenskap och beprövad erfarenhet. Tandvård

Detta är den nionde skriften i forskningsprogrammet Vetenskap och beprövad erfarenhets (VBE:s) skriftserie om begreppet vetenskap och beprövad erfarenhet. Denna gång är skriften resultatet av ett pågående samarbete med forskningsprogrammet Foresight vid Malmö universitet. Foresights forskning är inriktad på att hitta nya verktyg för att identifiera patienter som löper ökad risk för karies och tand

User related input data for energy usage calculations the case of low-energy schools in Sweden

In order to calculate building energy usage, apart from the technical characteristics, user related factors needs to be determined. Unless the user related factors are determined by specific project, the idea is to apply a standardized list of input data for a normal operation during a normal year, so the calculated energy value does not depend on variation of these factors. Such list was issued b

Factors associated with higher occupational balance in people with anxiety and/or depression who require occupational therapy treatment

Background: Anxiety and depressive disorders are associated with problems with everyday occupations, including difficulties achieving occupational balance. The aim of this cross-sectional study was to describe occupational balance in people suffering from anxiety and/or depression and the factors that are associated with better self-rated occupational balance. Material: One hundred and eighteen pa

Applying Causal Inference Methods in Psychiatric Epidemiology : A Review

Importance: Associations between putative risk factors and psychiatric and substance use disorders are widespread in the literature. Basing prevention efforts on such findings is hazardous. Applying causal inference methods, while challenging, is central to developing realistic and potentially actionable etiologic models for psychopathology. Observations: Causal methods can be divided into randomi

Below-ground responses to insect herbivory in ecosystems with woody plant canopies : A meta-analysis

Insect herbivory can have important consequences for the functioning of terrestrial ecosystems. Despite a growing recognition of the role of herbivores in above-ground–below-ground interactions, our current understanding is mainly restricted to studies of vertebrates in grassland and tundra ecosystems, while ecosystems with tree-like canopies (termed forests below) and invertebrates remain underst

The Origins of Ashkenaz, Ashkenazic Jews, and Yiddish

Recently, the geographical origins of Ashkenazic Jews (AJs) and their native language Yiddish were investigated by applying the Geographic Population Structure (GPS) to a cohort of exclusively Yiddish-speaking and multilingual AJs. GPS localized most AJs along major ancient trade routes in northeastern Turkey adjacent to primeval villages with names that resemble the word "Ashkenaz." These finding

Reconstructing Druze population history

The Druze are an aggregate of communities in the Levant and Near East living almost exclusively in the mountains of Syria, Lebanon and Israel whose ~1000 year old religion formally opposes mixed marriages and conversions. Despite increasing interest in genetics of the population structure of the Druze, their population history remains unknown. We investigated the genetic relationships between Isra

Geographic variation in plant community structure of salt marshes : species, functional and phylogenetic perspectives

In general, community similarity is thought to decay with distance; however, this view may be complicated by the relative roles of different ecological processes at different geographical scales, and by the compositional perspective (e.g. species, functional group and phylogenetic lineage) used. Coastal salt marshes are widely distributed worldwide, but no studies have explicitly examined variatio

Draft genome of the globally widespread and invasive Argentine ant (Linepithema humile)

Ants are some of the most abundant and familiar animals on Earth, and they play vital roles in most terrestrial ecosystems. Although all ants are eusocial, and display a variety of complex and fascinating behaviors, few genomic resources exist for them. Here, we report the draft genome sequence of a particularly widespread and well-studied species, the invasive Argentine ant (Linepithema humile),

Identifying compositionally homogeneous and nonhomogeneous domains within the human genome using a novel segmentation algorithm

It has been suggested that the mammalian genome is composed mainly of long compositionally homogeneous domains. Such domains are frequently identified using recursive segmentation algorithms based on the Jensen-Shannon divergence. However, a common difficulty with such methods is deciding when to halt the recursive partitioning and what criteria to use in deciding whether a detected boundary betwe

Can GC content at third-codon positions be used as a proxy for isochore composition?

The isochore theory depicts the genomes of warm-blooded vertebrates as a mosaic of long genomic regions that are characterized by relatively homogeneous GC content. In the absence of genomic data, the GC content at third-codon positions of protein-coding genes (GC3) was commonly used as a proxy for the GC content of isochores. Oddly, in the postgenomic era, GC3 is still sometimes used as a proxy f

The genome sequence of taurine cattle : a window to ruminant biology and evolution

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a

Cross-species analysis of genic GC3 content and DNA methylation patterns

The GC content in the third codon position (GC(3)) exhibits a unimodal distribution in many plant and animal genomes. Interestingly, grasses and homeotherm vertebrates exhibit a unique bimodal distribution. High GC(3) was previously found to be associated with variable expression, higher frequency of upstream TATA boxes, and an increase of GC(3) from 5' to 3'. Moreover, GC(3)-rich genes are predom

Gene expression and nucleotide composition are associated with genic methylation level in Oryza sativa

BACKGROUND: The methylation of cytosines at CpG dinucleotides, which plays an important role in gene expression regulation, is one of the most studied epigenetic modifications. Thus far, the detection of DNA methylation has been determined mostly by experimental methods, which are not only prone to bench effects and artifacts but are also time-consuming, expensive, and cannot be easily scaled up t

MetaDL : Declarative program analysis for the masses

While Datalog provides a high-level language for expressing static program analyses, it depends on external tooling to extract the input facts from the analyzed programs. To remove this dependency, we present MetaDL. The MetaDL system consists of a Datalog language extension for source-level program analysis and tools for generating the language extension from a description of the analyzed languag

Evaluation of NV556, a Novel Cyclophilin Inhibitor, as a Potential Antifibrotic Compound for Liver Fibrosis

Hepatic fibrosis can result as a pathological response to nonalcoholic steatohepatitis (NASH). Cirrhosis, the late stage of fibrosis, has been linked to poor survival and an increased risk of developing hepatocellular carcinoma, with limited treatment options available. Therefore, there is an unmet need for novel effective antifibrotic compounds. Cyclophilins are peptidyl-prolyl cis-trans isomeras

The Life and Death of Residential Room Types : A Study of Swedish Building Plans, 1750–2010

While the study of building types is a well-known and relatively active research field, the topic of room types is less explored. This article takes a broad approach to spatial categorization, enabling the examination of different types of spaces over longer periods. How do different room types evolve and die? How do the different residential room types relate to each other? Do they act alone or d

Validation of SDN policies: a property-based testing perspective

Software-defined networks are being widely adopted and used in large and complex networks supporting critical operations. Their increasing importance highlights the need for effective validation of SDN topologies and routing policies both prior and during operation. The policies that configure an SDN deployment come from several, possibly conflicting sources. This may lead to undesired effects suc
