Fractures of the olecranon: a 15- to 25-year followup of 73 patients.
Structure function relationships in the lymphatic system and implications for cancer biology
The lymphatic system, composed of lymphatic vessels, lymph, lymph nodes, and lymphocytes, is a distinctive vasculature (discontinuous basement membrane, open endothelial junctions, anchoring filaments, valves, and intrinsic contractility), different yet similar to the blood vasculature; an integral component of the plasma-tissue fluid-lymph circulation (the "blood-lymph loop"); and the center of t
Comparison of plasma and urinary levels of 2-hydroxyestrogen and 16 alpha-hydroxyestrogen metabolites
A modified ELISA assay for measurement of the two estrogen metabolites 2-hydroxyestrone (2OHE1) and 16 alpha-hydroxyestrone (16 alpha OHE1) in plasma and serum has been developed. Previously, these have only been measured in urine. It is not known how well the measurements of these metabolites in urine and plasma are correlated. The goal of this study was to compare urinary and plasma levels of 2O
Satellite tracking of Swedish Ospreys Pandion haliaetus: Autumn migration routes and orientation
Autumn migration routes and orientation of Swedish Ospreys Pandion haliaetus were studied by satellite tracking of 18 birds. Of these. 13 could be followed during the entire migration (6 females, 5 males and 2 juveniles). Most birds migrated across western and central Europe to winter in tropical West Africa. However, one juvenile flew to Cameroon and one Female used a very easterly route and reac
A time-variant analysis of the 1/f2 phase noise in CMOS parallel LC-tank quadrature oscillators
This paper presents a study of 1/f/sup 2/ phase noise in quadrature oscillators built by connecting two differential LC-tank oscillators in a parallel fashion. The analysis clearly demonstrates the necessity of adopting a time-variant theory of phase noise, where a more simplistic, time-invariant approach fails to explain numerical simulation results even at the qualitative level. Two topologies o
Palaeovegetation-model comparisons: climate change and tree succession in Scandinavia over the past 1500 years.
The Transcobalamin (TC) Codon 259 Genetic Polymorphism Influences Holo-TC Concentration in Cerebrospinal Fluid from Patients with Alzheimer Disease.
Recent developments in clinimetric instruments
Assessment of impairment and function is essential in order to monitor joint status and evaluate therapeutic interventions in patients with haemophilia. The improvements in the treatment of haemophilia have required the development of more sensitive tools to detect the more minor dysfunctions that may now be apparent. This paper outlines some of the recent developments in this field. The Haemophil
One-Year Survival of Extremely Preterm Infants After Active Perinatal Care in Sweden
Context Up-to-date information on infant survival after extremely preterm birth is needed for assessing perinatal care services, clinical guidelines, and parental counseling. Objective To determine the 1-year survival in all infants born before 27 gestational weeks in Sweden during 2004-2007. Design, Setting, and Patients Population-based prospective observational study of extremely preterm infant
Laser doppler perfusion monitoring of skin blood flow at different depths in finger and arm upon local heating.
Efficient transduction of neurons using Ross River glycoprotein-pseudotyped lentiviral vectors.
Lentiviral vectors are promising tools for CNS gene transfer since they efficiently transduce the cells of the nervous system in vivo. In this study, we have investigated the transduction efficiency of lentiviral vectors pseudotyped with Ross River virus glycoprotein (RRV-G) (RRV-G-pseudotyped lentiviral vectors (RRV-LV)). The RRV is an alphavirus with an extremely broad host range, including the
Conflicting perspectives on water in a Swedish railway tunnel project
The building of a railway tunnel through the Hallandsas ridge in the southwest of Sweden resulted in sinking groundwater levels and a toxic spill for the local community. As a result, this highly technological project expanded from the addressing of technological and economic issues of rail traffic and tunnel building to include issues of environmental harm and how to assess and manage the geology
The effect of selective phosphodiesterase inhibitors on mucociliary activity in the upper and lower airways in vitro
Bronchodilatory substances such as the phosphodisterase inhibitor (PDE-I) theophylline stimulate mucociliary activity. With the introduction of selective PDE-Is it has become possible to study the functional importance of each phosphodiesterase enzyme (PDE) concerning the regulation of the ciliary beat. The effects of rolipram (inhibiting a cAMP specific PDE (PDE4), milrinone (inhibiting a cGMP in
Circulating cytokine profile in anti-neutrophilic cytoplasmatic autoantibody-associated vasculitis: prediction of outcome?
AIMS: The anti-neutrophilic cytoplasmatic autoantibody-associated vasculitides (AASV) are diseases of relapsing-remitting inflammation. Here we explore the cytokine profile in different phases of disease, looking for pathogenic clues of possible prognostic value. Results: Interleukin (IL)-6, IL-8 and IL-10 were significantly elevated in plasma. Patients in the stable phase who subsequently develop

Phosphorus Availability Influences Elemental Uptake in the Mycorrhizal Fungus Glomus intraradices, as Revealed by PIXE Analysis.
We investigated element accumulation in the arbuscular mycorrhizal fungus Glomus intraradices. Fungal spores and mycelium growing in monoxenic cultures were analyzed. The elemental composition was quantified using particle-induced X-ray emission (PIXE) in combination with scanning transmission ion microscopy. In the spores, Ca and Fe were mainly associated with the spore wall; while P and K showed
Avian pectoral muscle size rapidly tracks body mass changes during flight, fasting and fuelling
We used ultrasonic imaging to monitor short-term changes in the pectoral muscle size of captive red knots Calidris canutus. Pectoral muscle thickness changed rapidly and consistently in parallel with body mass changes caused by flight, fasting and fuelling. Four knots flew repeatedly for 10 h periods in a wind tunnel. Over this period, pectoral muscle thickness decreased in parallel with the decre
Anisotropic ultrafast dissociation probed by the Doppler effect in resonant photoemission from CF4
The resonant Auger spectrum from the decay of F 1s-excited CF4 is measured. Several lines exhibit a nondispersive kinetic energy as the exciting photon energy is tuned through the resonance region. The F 1s(-1) atomiclike Auger line is split into two components due to the emission of Auger electrons by a fragment in motion, when electron emission is observed along the polarization vector of the li
Chlamydia trachomatis infection and persistence of human papillomavirus.
Human papillomavirus (HPV) persistence is the major cause of cervical cancer, but most HPV infections will not persist and risk factors for HPV persistence are not well known. Chlamydia (C.) trachomatis infection seems to also be associated with cervical cancer. We investigated whether C. trachomatis infection is a risk factor for HPV persistence. In a cohort of 12,527 women participating in a pop
