Mobility particle size spectrometers often referred to as DMPS (Differential Mobility Particle Sizers) or SMPS (Scanning Mobility Particle Sizers) have found a wide range of applications in atmospheric aerosol research. However, comparability of measurements conducted world-wide is hampered by lack of generally accepted technical standards and guidelines with respect to the instrumental set-up, me
Molecular dynamics (MD) simulations give atomically detailed information on structure and dynamics in amphiphilic bilayer systems on timescales up to about 1 μs. The reorientational dynamics of the C-H bonds is conventionally verified by measurements of (13)C or (2)H nuclear magnetic resonance (NMR) longitudinal relaxation rates R1, which are more sensitive to motional processes with correlation t
Abstract In plasma-assisted combustion, electric energy is added to the flame where the electric energy will be transferred to kinetic energy of the free electrons that, in turn, will modify the combustion chemical kinetics. In order to increase the understanding of this complex process, the influence of one of the products of the altered chemical kinetics, ozone (O3), has been isolated and studie
Many functions of galectin-3 entail binding of its carbohydrate recognition site to glycans of a glycoprotein, resulting in cross-linking thought to be mediated by its N-terminal non-carbohydrate-binding domain. Here we studied interaction of galectin-3 with the model glycoprotein asialofetuin (ASF), using a fluorescence anisotropy (FA) assay to measure the concentration of free galectin carbohydr
Digital image correlation (DIC) can measure full-field surface strains during mechanical testing of hard and soft tissues. When compared to traditional methods, such as strain gauges, DIC offers larger validation data (similar to 50,000 points) for, e.g., finite element models. Our main aim was to evaluate the repeatability of surface strain measurements with DIC during compressive testing of comp
Should boxing be banned? Do the ever-so-obvious risks outweigh everyone's freedom to choose whether to expose oneself to these risks by taking up the sport? On an official level, the RCN in the UK has taken its stand--it does not! So has also the British Medical Association (BMA)--it does! With few exceptions, the responding nurses from Europe, America, and Australia in this month's column seem to
In areas where tectonics and weathering have hydrogeological significance, electrical methods can assist in mapping the subsurface. In this work, resistivity imaging was used to map fractures, faults and quartz veins emplaced in strongly weathered volcanic rocks. The aim was to map geological units related to the formation of groundwater systems in the Rio Artiguas basin, Nicaragua. Eight 2D resis
Background: There has been a controversy regarding the cause of brachioradial pruritus: is it caused by a nerve compression in the cervical spine or is it caused by a prolonged exposure to sunlight? Objective: The purpose was to study clinical features of patients with brachioradial pruritus and to compare the cutaneous innervation in punch biopsies from the itchy skin of patients with the age-mat
Objective: To investigate whether intermittent short-term courses of penicillin V (PcV) administered as intermittent prophylaxis against acute otitis media (AOM) during upper respiratory tract infections altered the nasopharyngeal bacterial. flora and/or its susceptibility to penicillin. Methods: In a double blind, placebo controlled study 70 children (30 in the PcV group and 40 in the placebo gro
Objective: Body mass index (BMI) is associated with increased incidence of cardiovascular disease (CVD). However, the risk could be very different for individuals with the same body mass. The present study explored whether regional fat distribution, as measured by waist-hip ratio (WHR), could modify the impact of BMI on the risk of CVD in men and women. Design: Prospective population-based study.
Objective. To investigate the incidence of noncardiac vascular disease in patients with rheumatoid arthritis (RA) and its relationship to systemic extraarticular disease in a community-based cohort. Methods. A retrospective medical record review of 609 patients with incident RA diagnosed during 19551994 was carried out in Olmsted County, Minnesota. Patients were followed up from 1955 to 2000 (medi
In vitro, expanded neurospheres exhibit multipotent properties and can differentiate into neurons, astrocytes and oligodendrocytes. In vivo, cells from neurospheres derived from mouse fetal forebrain have previously been reported to predominantly differentiate into glial cells, and not into neurons. Here we isolated stem/progenitor cells from E13.5 lateral ganglionic eminence (LGE), medial ganglio
Background: Inguinal hernia repair is the most common operation in general surgery. Prosthetic reinforcement of the inguinal area with polypropylene mesh has increased dramatically in the last decade. The aim of this study was to evaluate how different types of mesh affect the spermatic cord structures. Methods: Thirty rats were divided into three groups. The spermatic cord was dissected free and
Purpose: Hypoxia in breast cancer is associated with poor prognosis and down-regulation of the estrogen receptor. Carbonic anhydrase IX (CA IX) is a hypoxia-inducible gene that has been associated with poor outcome in many epithelial cancers. Previous studies of CA IX in breast cancer have been carried out on mixed cohorts of premenopausal and postmenopausal patients with locally advanced disease
Information on objectively assessed physical activity in elderly people is scarce. The aim of this study was to investigate accelerometer measures in elderly women, and its relation to other indices of physical activity and bone density. A subset of 57 women, all 80 years old, (range 80.0-80.7) of the Malmo OPRA study was equipped with an MTI accelerometer for a period of 5-7 days. A 7-day activit
Most, but not all, studies have found that women with a high urinary 2-hydroxyestrogen (2OHE) to 16 alpha-hydroxyestrone (16 alpha OHE1) ratio are at reduced risk for breast cancer and have a better prognosis. The aim was to identify factors associated with the pre-operative 2OHE to 16 alpha OHE1 ratio and factors that predicted the change in the ratio between the pre-operative visit and first fol
Popular Abstract in DanishLivsbaner gennem et felt viser hvorledes eliteidrætsudøvere klarer sig i samfundet efter livet i sporten. Spørgsmålet er om erhvervelse af fysisk sportskapital i sportsfeltet, medieret gennem berømmelse, medvirker til at opnå et arbejde eller en bestemt placering i samfundet. Sportskapital bidrager måske til social mobilitet. Dette er belyst gennem konkrete undersøgelser The thesis deals with a theoretical outline of the theory of reconversions in the light of the social space, with an analysis of top level athletes' mobility and strategies of reconversions in their trajectories through the relative autonomous field of sports. Some disciplines in this field have much autonomy, others less, and are positioned according to a state of distribution of the specific cap
The aim of this study was to determine the threshold of fracture probability at which interventions become cost-effective. We modeled the effects of a treatment costing $500/year, given for 5 years, that decreased the risk of all osteoporotic fractures by 35%, followed by a waning of effect for 5 years. Sensitivity analyses included a range of effectiveness (10%-50%) and a range of intervention co
Rodent models have been developed to study the pathogenesis of diseases caused by Helicobacter pylori, as well as by other gastric and intestinal Helicobacter spp., but some murine enteric Helicobacter spp. cause hepatobiliary and intestinal tract diseases in specific inbred strains of laboratory mice. To identify these murine Helicobacter spp., we developed an assay based on PCR-denaturing gradie
