The antiviral activities of type I IFNs have long been established. However, comparatively little is known of their role in defenses against nonviral pathogens. We examined here the effects of type I IFNs on host resistance against the model pathogenic yeast Cryptococcus neoformans. After intratracheal or i.v. challenge with this fungus, most mice lacking either the IFN-alpha/beta receptor (IFN-al

The unperturbed neutron brightness of a moderator can be defined from the number of neutrons leaving the surface of a moderator completely surrounded by a reflector. Without openings for beam extraction, it is the maximum brightness that can be theoretically achieved in a moderator. The unperturbed brightness of a cylindrical cold moderator filled with pure para-H-2 was calculated using MCNPX; the

Given that nonsuicidal self-injury (NSSI) is prevalent in adolescents, structured assessment is an essential tool to guide treatment interventions. The Functional Assessment of Self-Mutilation (FASM) is a self-report scale that assesses frequency, methods, and functions of NSSI. FASM was administered to 3,097 Swedish adolescents in a community sample. With the aim of examining the underlying facto

Background Recanalization of arterial duct (AD) is rarely needed. Objective The aim of this study is to report our experience regarding the feasibility and effectiveness of arterial duct recanalization in three infants and review the relevant literature. Methods and results We report on three patients with decreased pulmonary blood flow after initial palliation. The first patient had pulmonary atr

The contiguity and phase of sequence information are intrinsic to obtain complete understanding of the genome and its relationship to phenotype. We report the fabrication and application of a novel nanochannel design that folds megabase lengths of genomic DNA into a systematic back-and-forth meandering path. Such meandering nanochannels enabled us to visualize the complete 5.7 Mbp (1mm) stained DN

Popular Abstract in Swedish Varje dag producerar vår kropp många miljarder nya blodceller. Dessa celler är livsnödvändiga för att många funktioner i kropp ska fungera. Exempelvis hjälper de till med att skydda oss från sjukdomar, läka skador, och med att transportera syre och avfallsämnen. Blodsystemet (det hematopoetiska systemet) är uppbyggt som en hierarki där hematopoetiska stamceller finns påIn the blood system, knowledge on the regulation of hematopoietic stem cells (HSCs) and their immature progeny has provided roadmaps of differentiation. Such information can also have a value to understand the etiology of hematological cancers, since clinical heterogeneity and prognostic therapeutic outcomes have been proposed to associate with the specific developmental stage from which the trans

Evidence suggests that in addition to sequestering carbon (C), biochar amendment can increase crop yields, improve soil quality and nutrient cycling, reduce the leaching of nutrients from soil and stimulate soil microbial activity. However, biochar application primarily benefits soils of intrinsic poor quality, thus the advantages of adding biochar to temperate agricultural soils remains controver

This article aims to share experience from a Swedish project on the introduction and implementation of Open Educational Resources (OER) in higher education with both national and international perspectives. The project, OER – resources for learning, was part of the National Library of Sweden Open Access initiative and aimed at exploring, raising awareness of and disseminating the use of OER and th

BACKGROUND: To investigate, in a rabbit model, the effect of two different doses of vigabatrin (VGB) on retinal function and morphology. METHODS: Twenty-nine rabbits of mixed strain were divided into two groups, receiving either high-dose (n = 15) or low-dose (n = 14) oral VGB treatment (cumulative dose 29.8 +/- 2.9 g and 14.2 +/- 0.6 g respectively). Ten rabbits receiving water served as control

Haploid hybrid gametophytes are often present at low frequencies in sympatric populations of Sphagnum capillifolium and Sphagnum quinquefarium. We used intersimple sequence repeat (ISSR) markers and polymerase chain reaction-restriction fragment length polymorphism of the trnL(UAA) intron of the chloroplast genome to reveal the nuclear and chloroplast composition of mature hybrid gametophytes from

In plant respiratory chains, alternative pathways for NAD(P)H oxidation are mediated by type II NAD(P)H dehydrogenases belonging to the NDA, NDB, and NDC families. For the latter type, Arabidopsis thaliana contains a single gene, NDC1, whose functional role has not previously been analyzed in the plant. We found that A. thaliana NDC1 is alternatively spliced. Four base pairs at the 3' end of intro

In insects, the surface area of the compound eye increases with body size both within and between species with only a slight negative allometry. This increase in surface area permits changes in eye structure that affect the eye's acuity and sensitivity, two features of eye performance that cannot be simultaneously maximized. Hence, as eye size varies within a lineage, so will the compromises betwe

HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells) is a complex of partially unfolded human alpha-lactalbumin and oleic acid that kills many different types of tumor cells and shows therapeutic efficacy in animal models and clinical studies. This thesis aims to (1) elucidate the structure of HAMLET and the exposure of biologically active domains, (2) define the contribution of lipids to t

The present study was designed to delineate the presence of COMP at the ultrastructural level comparing concentrations between two areas of articular cartilage from the equine third carpal bone, subjected to different loading, from trained and untrained horses. We also analyzed the fibril thickness of collagen type II in the same compartments and zones. Samples were collected from high load-bearin

The concentrations of the monoamine metabolites homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA) and 3-methoxy-4-hydroxyphenylglycol (HMPG) in the cerebrospinal fluid (CSF) of patients with clinical frontotemporal dementia (FTD; n = 30), early onset Alzheimer's disease (EAD; n = 33), late onset Alzheimer's disease (LAD, n = 27) and normal controls (n = 31) were determined using HPLC. A

Background: Recent studies on the pathophysiology of heart failure indicate the role of neurohormones and immune and inflammatory processes as potential mechanisms involved in the pathogenesis and clinical course of chronic heart failure (CHF). Aim: To analyse the relationship between concentrations of brain natriuretic peptide (BNP), endothelin-1 (ET-1), inflammatory cytokines (TNF-alpha, IL-6) a

A disturbed proprioception has been described in patients with an anterior cruciate ligament (ACL) deficient knee. The relation to demographic data and to different commonly associated anatomical lesions, as well as to subjective knee function, was prospectively studied in 16 consecutive patients after an acute knee ligament injury. All patients had a complete rupture of the ACL, but variable asso

Decreased information processing speed (mental slowing) is a known sequelae of many brain disorders, and can be assessed by continuous naming tasks. Functional imaging studies have shown that pause and articulation times in continuous speech are normally associated with different brain regions, but knowledge about such association in dementia is lacking. We therefore tested the hypothesis that per

This paper, the first in a series on the automatic generation of detailed hydrocarbon mechanisms for hydrocarbons, describes how generalized reaction types, specifically the 25 types outlined by Curran et al. for heptane and isooctane combustion, can be translated into general reaction classes. Each type description from Curran et al. ranges from specific, such as differentiating among 1degrees, 2

Background Methadone and buprenorphine are well-documented treatment options for opiate dependence, and there is substantial evidence to support adjunct psychosocial support for methadone maintenance treatment. Although drug-free treatment is preferred by a large number of patients and has considerable political support, less is known about treatment to support and maintain complete abstinence fro
