Endothelin receptor-mediated vasodilatation: Effects of organ culture.

Culture of intact arteries is a frequently employed experimental model for investigating the mechanisms governing the regulation of vascular endothelin receptors. Endothelin type A (ETA) and type B (ETB) receptors on vascular smooth muscle cells are up-regulated in organ culture and the enhanced vasoconstriction mimics the changes that occur in cardiovascular disease. The effect of organ culture o

Dynamic changes of brain-derived neurotrophic factor protein levels in the rat forebrain after single and recurring kindling-induced seizures

Regional levels of brain-derived neurotrophic factor protein were measured in the rat brain using enzyme immunoassay following seizures evoked by hippocampal kindling stimulations. One stimulation, which induced a brief, single episode of epileptiform activity in hippocampus and piriform cortex but not in parietal cortex or striatum, gave rise to a transient increase of brain-derived neurotrophic

Individualized monitoring of drug bioavailability and immunogenicity in rheumatoid arthritis patients treated with the tumor necrosis factor alpha inhibitor infliximab

Objective. Infliximab, an anti-tumor necrosis factor alpha (anti-TNF alpha) antibody, is effective in the treatment of several immunoinflammatory diseases. However, many patients experience primary or secondary response failure, suggesting that individualization of treatment regimens may be beneficial. This study was undertaken to investigate whether serologic monitoring of infliximab bioavailabil

Glycosaminoglycans inhibit the antibacterial activity of LL-37 in biological fluids

Objectives: The antibacterial activity of antimicrobial peptides is influenced by various factors such as salt content, pH and the presence of proteins. In this study, we explored the antibacterial action of the human cathelicidin LL-37 in physiologically relevant conditions, i.e. various human wound fluids, human plasma fractions and serum. Methods: Radial diffusion assays using Staphylococcus au

Monitor – biology

The hottest developments in the fields of cancer research, neuroscience, genomics and proteomics, anti-virals and more, with a pick of the key research papers in these areas.

Leadership and implementation of evidence-based practices

Purpose – This paper seeks to investigate the role of leadership styles in the implementation of evidence-based treatment methods (EBP) for drug abuse and criminal behaviour. Design/methodology/approach – The paper employs a triangulation approach through mail questionnaires to 112 treatment personnel (49 per cent response rate), interviews with 65 employees and managers, observations and feedbac

Catastrophic health payments and health insurance: Some counterintuitive evidence from one low-income country.

Objectives: The purpose of the study is to quantitatively analyze the role of health insurance in the determinants of catastrophic health payments in a low-income country setting. Methods: The study uses the most recent publicly available household level data from Zambia collected in 1998 containing detailed information on health care utilization and spending and on other key individual, household

Identification of human candidate genes for male infertility by digital differential display

Evidence for the importance of genetic factors in male fertility is accumulating. In the literature and the Mendelian Cytogenetics Network database, 265 cases of infertile males with balanced reciprocal translocations have been described. The candidacy for infertility of 14 testis-expressed transcripts (TETs) were examined by comparing their chromosomal mapping position to the position of balanced

Thoughts and experiences from returning to work after stroke.

Objective: The aim of this study was to increase the understanding of stroke survivors' thoughts and experiences from returning to work after stroke. Methods: Semi-structured interviews were carried out with twelve persons, based on a thematic interview guide. A qualitative content analyse were performed. Results: The main theme; was Striving for optimal function at work creates mixed feelings of

Early nutrition causes persistent effects on pheasant morphology

Differences in growth conditions during early ontogeny have been suggested to cause permanent effects on the morphology and quality of birds. Yearly variation in growth conditions could thus result in morphological and quality differences between cohorts. In this study, we investigated the effect of small differences in the dietary protein content of captive ring-necked pheasants (Phasianus colchi

The Swedish economy in the early modern period: constructing historical national accounts

A new GDP series per capita for Sweden during 15601800 is presented, linked to slightly revised data for 18002000. Long-term stagnation up to the nineteenth century is revealed but with secular changes. Growth characterized much of the seventeenth century with modernization of state administration, industry and trade. In the next century, stagnation and even retrogression followed. Wars in the sev

Summary of the recommendations of the EFNS/MDS-ES review on therapeutic management of Parkinson's disease

Objective: To summarize the 2010 EFNS/MDS-ES evidence-based treatment recommendations for the management of Parkinson's disease (PD). This summary includes the treatment recommendations for early and late PD. Methods: For the 2010 publication, a literature search was undertaken for articles published up to September 2009. For this summary, an additional literature search was undertaken up to Decem

Nurse-led interventions in the concept of randomized controlled trials – critical perspectives on how to handle social contexts

This article focuses on the randomized clinical trial (RCT) as research method in nursing interventions and problematizes its methodological ability and delimitations considering the use of this method in the healthcare. It aims to examine if and how RCT in nurse-led interventions are handling questions concerned with contextual in fluences. A systematic literature review was conducted, consisting

Prospective study of merkel cell polyomavirus and risk of merkel cell carcinoma.

Merkel cell carcinoma (MCC) is a rare type of skin cancer that has a characteristically increased incidence among immunosuppressed subjects. The DNA of Merkel cell polyomavirus (MCV) is regularly found in most MCC tumors. We investigated whether Merkel cell polyomavirus (MCV) infection increases the risk for future Merkel cell carcinoma (MCC). Two large biobank cohorts (Southern Sweden Microbiolog

Heparin-binding protein (HBP) in critically ill patients with influenza A (H1N1) infection

Heparin-binding protein (HBP) is an inducer of vascular endothelial leakage in severe infections. Fluid accumulation into alveoli is a general finding in acute respiratory distress syndrome (ARDS). Severe acute respiratory failure with ARDS is a complication of influenza A(H1N1) infection. Accordingly, we studied the HBP levels in critically ill patients with infection of influenza A(H1N1).Critica

Changes in organic phosphorus composition in boreal forest humus soils: the role of iron and aluminium

Organic phosphorus (P) is an important component of boreal forest humus soils, and its concentration has been found to be closely related to the concentration of iron (Fe) and aluminium (Al). We used solution and solid state P-31 NMR spectroscopy on humus soils to characterize organic P along two groundwater recharge and discharge gradients in Fennoscandian boreal forest, which are also P sorption
