Effects of propranolol and clonidine on brain edema, blood-brain barrier permeability, and endothelial glycocalyx disruption after fluid percussion brain injury in the rat

BACKGROUND Traumatic brain injury causes a disruption of the vascular endothelial glycocalyx layer that is associated with an overactivation of the sympathoadrenal system. We hypothesized that early and unselective beta-blockade with propranolol alone or in combination with the alfa2-agonist clonidine would decrease brain edema, blood-brain barrier permeability, and glycocalyx disruption at 24 hou

Electrospinning of food-grade nanofibres from whey protein

In this study, electrospinning has been employed to produce micro to nano scale fibres of whey protein in order to investigate their potential for use in the food industry. Initially, spinning of pure whey protein proved challenging; so in order to facilitate the spinning of freshly prepared aqueous solutions, small amounts of polyethylene oxide (as low as 1% w/w in solution) were incorporated in

Sex as predictor for achieved health outcomes and received care in ischemic stroke and intracerebral hemorrhage : A register-based study

Background: Differences in stroke care and health outcomes between men and women are debated. The objective of this study was to explore the relationship between patients' sex and post-stroke health outcomes and received care in a Swedish setting. Methods: Patients with a registered diagnosis of acute intracerebral hemorrhage (ICH) or ischemic stroke (IS) within regional administrative systems (IC

Balancing stakeholder interests : Socio-technical perspectives on smart working practice

The advantages put forward for so-called Smart working may sound very appealing. However, it is unlikely that all stakeholder groups involved will benefit to the same extent, if at all. Many initiatives that seem to be aimed at development of Smart work systems can be seen to be flawed, since they are suggested to support empowerment but are expressed in terms of pre-defined ‘best practice’. This

Daily duration of long-term oxygen therapy and risk of hospitalization in oxygen-dependent COPD patients

Introduction: Long-term oxygen therapy (LTOT) improves survival and may reduce hospital admissions in patients with chronic obstructive pulmonary disease (COPD) and severe hypoxemia, but the impact of daily duration of LTOT on hospitalization rate is unknown. We aimed to estimate the association between the daily duration of LTOT (24 vs 15 h/d) and hospital admissions in patients with LTOT due to

Caesarean section performed by medical doctors and associate clinicians in Sierra Leone

BACKGROUND: Many countries lack sufficient medical doctors to provide safe and affordable surgical and emergency obstetric care. Task-sharing with associate clinicians (ACs) has been suggested to fill this gap. The aim of this study was to assess maternal and neonatal outcomes of caesarean sections performed by ACs and doctors. METHODS: All nine hospitals in Sierra Leone where both ACs and doctors

The combined effects of FADS gene variation and dietary fats in obesity-related traits in a population from the far north of Sweden : the GLACIER Study

Background: Recent analyses in Greenlandic Inuit identified six genetic polymorphisms (rs74771917, rs3168072, rs12577276, rs7115739, rs174602 and rs174570) in the fatty acid desaturase gene cluster (FADS1-FADS2-FADS3) that are associated with multiple metabolic and anthropometric traits. Our objectives were to systematically assess whether dietary polyunsaturated fatty acid (PUFA) intake modifies

Inelastic hyperspectral lidar for aquatic ecosystems monitoring and landscape plant scanning test

We have developed an aquatic inelastic hyperspectral lidar with unrestricted focal-depth and enough sensitivity and spatio-temporal resolution to detect and resolve position and behavior of individual sub-millimeter aquatic organisms. We demonstrate ranging with monitoring of elastic echoes, water Raman signals and fluorescence from chlorophyllbearing phytoplankton and dye tagged organisms. The sy

Experimental evaluation of MIMO terminal antenna configurations in noise- and interference-limited urban scenarios

In this paper, we compare capacity performances of three terminal dual-antenna configurations at 2.65 GHz based on extensive 2 by 2 multiple-input multiple-output (MIMO) channel measurements in an urban macrocellular environment. Both noise- and interference-limited scenarios are investigated. Our results show that, on average over the measurement route, the capacity performance is mainly determin

Ultrahigh vacuum dc magnetron sputter-deposition of epitaxial Pd(111)/Al2O3(0001) thin films

Pd(111) thin films, ∼245 nm thick, are deposited on Al2O3(0001) substrates at ≈0.5Tm, where Tm is the Pd melting point, by ultrahigh vacuum dc magnetron sputtering of Pd target in pure Ar discharges. Auger electron spectra and low-energy electron diffraction patterns acquired in situ from the as-deposited samples reveal that the surfaces are compositionally pure 111-oriented Pd. Double-axis x-ray

Heterogeneity in childbirth related fear or anxiety

Many pregnant women experience fear, worry or anxiety relating to the upcoming childbirth. The aim of this cross-sectional study was to investigate possible subgroups in a sample of 206 pregnant women (mean age 29.4 years), reporting fear of birth in mid-pregnancy. Comparisons were made between nulliparous and parous women. In a series of cluster analyses, validated psychological instruments were

New functional test for the TFPIα cofactor activity of Protein S working in synergy with FV-Short

Essentials Protein S and FV-Short are synergistic cofactors to Tissue Factor Pathway Inhibitor α (TFPIα). An assay for the TFPIα synergistic cofactor activity of protein S with FV-Short was developed. The assay was specific for the synergistic TFPIα-cofactor activity of free protein S. Protein S deficient individuals with known mutations were correctly distinguished from controls. Summary: Backgro

Improved oncological treatment of anal cancer

Background: Squamous cell cancer of the anus (SCCA) is a rare malignancy, but the incidence is increasing. It isassociated with humman papilloma virus infection. The standard treatment is radiotherapy (RT) combined withchemotherapy, usually 5-fluorouracil (5FU)/Mitomycin C (MMC). This treatment is relatively effective, butrecurrence still represents a problem especially in locally advanced SCCA.Th

Measuring structural inhomogeneity of a helical conjugated polymer at high pressure and temperature

We report on X-ray scattering measurements of helical poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] by mapping the sample with 10 μm spatial resolution from 0.3 GPa to 36 GPa. We follow the strongest 00l reflection, which moves toward higher scattering angles with pressure indicating planarization of helical polyfluorene. Lateral inhomogeneity is increased for >10 GPa concomitant with the solidifi

Relationship between Perceived Indoor Temperature and Self-Reported Risk for Frailty among Community-Dwelling Older People

This study investigated the relationship between perceived indoor temperature in winter and frailty among community-dwelling older people. This cross-sectional study included 342 people 65 years and older in Japan. Participants answered questions about demographics, frailty, housing, and perceived indoor temperature in winter. Participants were grouped based on perceived indoor temperature (Cold o

Pesticide exposure among Bolivian farmers : associations between worker protection and exposure biomarkers

The use of pesticides has increased during the past decades, also increasing the risk of exposure to toxic pesticides that can cause detrimental health effects in the future. This is of special concern among farmers in low-to-middle-income countries that may lack proper training in the safe use of these chemicals. To assess the situation in Bolivia a cross-sectional study in three agricultural com

TGF-β1-induced deposition of provisional extracellular matrix by tracheal basal cells promotes epithelial-to-mesenchymal transition in a c-Jun NH2-terminal kinase-1-dependent manner

Epithelial cells have been suggested as potential drivers of lung fibrosis, although the epithelial-dependent pathways that promote fibrogenesis remain unknown. Extracellular matrix is increasingly recognized as an environment that can drive cellular responses in various pulmonary diseases. In this study, we demonstrate that transforming growth factor-β1 (TGF-β1)-stimulated mouse tracheal basal (M

The primary aim of this study was to examine the changes in objectively assessed physical activity levels following a culturally adapted lifestyle intervention program. The secondary aim was to examine the association between objectively assessed physical activity an

Osteoarthritis-related walking disability and arterial stiffness-results from a cross-sectional study

OBJECTIVES: To compare 6 minute walking distance (6MWD) in a population-based osteoarthritis (OA) cohort with matched peers from the general population, and to explore the associations between walking ability and CVD risk (arterial stiffness) in the OA cohort.DESIGN: This cross-sectional study included participants (40-80 years) who self-reported OA (n=500) in a population-based study and age- and

Gene-Environment Interactions for Metals

It has become increasingly clear that the individual genetic background influences susceptibility to metal toxicity. Genetic variation in genes that regulate metal toxicokinetics and toxicodynamics influence the degree of metal accumulation and retention in the body, as well as toxic effects. Moreover, factors that regulate gene expression, so-called epigenetic factors, have been identified as tar
