Isolation and partial characterization of a low molecular weight trypsin inhibitor from human urine
A low molecular weight glycoprotein which completely inhibited trypsin at a 1 : 1 molar ratio was isolated from human urine. It was generated from a precursor molecule which in turn derived from plasma inter-alpha-trypsin inhibitor. It had one polypeptide chain with a molecular weight of about 20 000 and a high content of half-cystine residues. Its amino-terminal amino-acid sequence was Val-Thr-Gl
Immunocapillarymigration with enzyme-labeled antibodies : rapid quantification of C-reactive protein in human plasma
Various procedures to improve the sensitivity and precision of antigen quantitation by immunocapillarymigration are investigated. The best results are obtained when using porous strips of cellulose acetate with covalently attached antibodies and when enzyme-labeled antibodies are used to expose the antigen-covered areas of the strips. Such a system has a sensitivity of 0.15 mg/liter and a precisio
A simple modification of Greiner electronics selective analyser G300 permitting use of capillary blood samples
A simple modification of Greiner electronics selective analyser G300 allowing direct transference of serum samples to the process tubes is described. The modified instrument permitted use of pediatric and capillary blood samples. Eight different capillary analyses were tested on the modified instrument and the results agreed with those obtained by the ordinary analytical macroprocedures of the ins

Isolation and some properties of an IgG Fc-binding protein from group A streptococci type 15
An IgG Fc-binding protein was isolated from alkaline extracts of group A streptococci type 15 by ion-exchange chromatography and immunosorption on an IgG column. Ample use of protease inhibitors was necessary to achieve successful isolation. 600 micrograms protein was obtained from 60 g bacteria (wet weight). The protein appeared homogeneous on agarose gel and sodium dodecyl sulfate polyacrylamide
Decreased PGC1beta expression results in disrupted human erythroid differentiation, impaired hemoglobinization and cell cycle exit
Production of red blood cells relies on proper mitochondrial function, both for their increased energy demands during differentiation and for proper heme and iron homeostasis. Mutations in genes regulating mitochondrial function have been reported in patients with anemia, yet their pathophysiological role often remains unclear. PGC1β is a critical coactivator of mitochondrial biogenesis, with incr
Elucidating regulators of red blood cell development in health and disease
Våra röda blodkroppar lever i genomsnitt 120 dagar och bryts därefter ner avmakrofagerna, immunsystemets medfödda städare av både främmande och egnaceller. De röda blodkropparnas uppgift är att transportera syre från lungorna tillkroppens olika vävnader och föra tillbaka koldioxid. Men vad händer om de rödablodkropparna bryts ner ovanligt snabbt eller helt enkelt inte produceras i tillräckligtsnabRed blood cells are are plentiful, flexible and essential. They are the most abundant cell in our body and their mainobject is to carry oxygen, which is essential for cellular respiration. The formation of red blood cells is callederythropoiesis. Erythropoiesis is intimately coupled to cell division and mitochondrial function. Aberrations in thesetwo processes are often associated with red blood c
Motor Imagery to Facilitate Sensorimotor Re-Learning (MOTIFS) after traumatic knee injury: : study protocol for an adaptive randomized controlled trial
BackgroundTreatment following traumatic knee injury includes neuromuscular training, with or without surgical reconstruction. The aim of rehabilitation is to restore muscle function and address psychological factors to allow a return to activity. Attention is often on rehabilitation of knee function, but deficiencies often persist. Specific interventions addressing psychological factors are sparin

Analysis of policy frameworks for ‘children in care’ in Sweden
In a joint South African and Swedish research study, policy frameworks for children in care were analysed in regard to children’s rights and accessibility to participate in decisions on care. The research group has during phase one in the study developed a series of questions to analyse the most relevant legislations in regard to children in care. Thus, for the Swedish part of the analysis four le
Distinct Molecular Signatures of Clinical Clusters in People with Type 2 Diabetes : an IMIRHAPSODY Study
Type 2 diabetes is a multifactorial disease with multiple underlying aetiologies. To address this heterogeneity a previous study clustered people with diabetes into five diabetes subtypes. The aim of the current study is to investigate the aetiology of these clusters by comparing their molecular signatures. In three independent cohorts, in total 15,940 individuals were clustered based on five clin
School-based hearing screening in Sweden – An evaluation of current practices
Objectives: Routines for school hearing screening vary between municipalities in Sweden, and no study has been carried out to investigate how this is conducted throughout the country. The aim of the present study was to determine the extent of school hearing screening, and how it is performed in all the municipalities in Sweden. Methods: An online survey was used to collect information on school h

Physical impairments in longstanding hip and groin pain : Cross-sectional comparison of patients with hip-related pain or non-hip-related groin pain and healthy controls
Objectives: To compare physical impairments between patients with hip-related pain and those with non-hip-related groin pain, and to compare both patient groups with healthy controls. Design: Cross-sectional. Participants: Eighty-one hip and groin pain patients were consecutively included and categorized into having hip-related pain or non-hip-related groin pain. Twenty-eight healthy controls were
Compensating for a stressful pregnancy? Glucocorticoid treatment during gravidity reduces metabolic rate in female fence lizards post-parturition
Reproduction is a critical part of an animal's life history, but one which incurs significant costs to survival and future reproductive potential. These physiological consequences are likely to be influenced by context – for example, if an individual is subject to environmental stressors, physiological and behavioral changes associated with reproduction may be altered. Glucocorticoids, hormones pr

Blood culture time to positivity in non-β-hemolytic streptococcal bacteremia as a predictor of infective endocarditis-a retrospective cohort study
Non-β-hemolytic streptococci (NBHS) cause infective endocarditis (IE) and a short blood culture time to positivity (TTP) is associated with risk of IE in bacteremia with other pathogens. In this retrospective population-based cohort study, we investigate if TTP is associated to IE or mortality. Of 263 episodes with NBHS bacteremia, 28 represented IE and the median TTP did not differ significantly
Ombordmätningar av partiklar och koldioxid i X60B förarhytter
SyfteMålsättningen med denna studie var dels att säkerställa att tågpersonalen inte utsätts för höga halter av partiklar i sitt arbete på X60B fordon som trafikerar Arlanda. Syftet var även att ta fram ett förhållande mellan partikelnivåerna i tunnelmiljö och ombord på pendeltågsfordon av typ X60B i förarhytterna för att avgöra ventilationsfiltrets kapacitet. Kunskapen om filtreringseffektiviteten
