Aims: Network for Pharmacoepidemiology (NEPI) Antidiabetes Study-Eye is a randomized placebo-controlled Swedish trial investigating if treatment with sulphonylurea, in addition to dietary regulation and increased exercise, delays the development of retinopathy in subjects with impaired fasting glucose (IFG). Methods: Subjects were surveyed in primary care with repeated fasting blood glucose measu
Far from being an extinct phenomenon, piracy still exists in the modern world and is a growing menace to the security and safety of shipping. Using the data on attacks against vessels reported between 1996 and 2005 merged with the data on the total world merchant fleet, this article inquires whether acts of piracy are a truly random occurrence. Results show that both flag of registry and type of v
Background: It is well known that severe mental illness (SMI) with concurrent substance use disorders (SUD) commonly occurs. This comorbidity has distressing social, psychological, psychiatric and somatic consequences. Aim: To gain greater understanding of how individuals with SMI and SUD experience the roles of alcohol and other drugs for their health and in their life situation. Method: Eight in
We investigated the association between occupational factors and risk of bone sarcoma, a rare tumor with a largely unknown aetiology. A multicentric case-control study was conducted in 7 European countries in 1995-97. Ninety-six cases aged 35-69 years with a centrally reviewed diagnosis of bone sarcoma (68 chondrosarcomas and 28 osteosarcomas) were compared to 2,632 population (68%) or colon cance
Streptococcus pyogenes of the M1 serotype is commonly associated with large outbreaks of invasive streptococcal infections and development of streptococcal toxic shock syndrome (STSS). The pathogenesis behind these infections is believed to involve bacterial superantigens that induce potent inflammatory responses, but the reason why strains of the M1 serotype are over-represented in STSS is still
Our purpose was to assess the role of MRI in evaluating the musculoskeletal system in athletes with chronic pain laterally in the groin of unknown etiology. Magnetic resonance imaging (MRI) of the pubic ring was performed in 11 young athletes (soccer players) with long-standing groin pain. MR findings were compared with plain films and isotope examination (bone scan Tc 99M). Abnormal MRI findings
The right ventricle (RV) provides sustained low-pressure perfusion of the pulmonary vasculature, but is sensitive to changes in loading conditions and intrinsic contractility. Factors that affect right ventricular preload, afterload or left ventricular function can adversely influence the functioning of the RV, causing ischaemia and right ventricular failure (RVF). As RVF progresses, a pronounced
Objective and design: The aim of this study was to investigate the impact of the isoflavone genistein on in vivo cell-mediated responses. In addition, we wanted to study the influence of genistein on collagen induced arthritis (CIA) in mice. Methods: Delayed type hypersensitivity reaction (DTH) to oxazolone and the inflammatory response to olive oil were measured in mice treated with genistein. In
Linear-accelerator-based sources will revolutionize ultrafast x-ray science due to their unprecedented brightness and short pulse duration. However, time-resolved studies at the resolution of the x-ray pulse duration are hampered by the inability to precisely synchronize an external laser to the accelerator. At the Sub-Picosecond Pulse Source at the Stanford Linear-Accelerator Center we solved thi
To attract users from a wide range of scientific areas it is important to provide a variety of ways to access the Lunarc resources. Providing good user interfaces for all categories of users is a key factor for a high use of resources. One way of doing this is by providing access to common applications through a web-based portal. Existing grid portals are often geared toward's providing access to
Summary Objective Patients with suspicion of acute coronary syndrome (ACS) are difficult to diagnose and they represent a very heterogeneous group. Some require immediate treatment while others, with only minor disorders, may be sent home. Detecting ACS patients using a machine learning approach would be advantageous in many situations. Methods and materials Artificial neural network (ANN) ensem
Background: Early cardiopulmonary resuscitation (CPR) by bystanders prior to the arrival of the rescue team has been shown to be associated with increased survival after out-of-hospital cardiac arrest. The aim of this survey was to evaluate the impact on survival of no bystander CPR, lay bystander CPR and professional bystander CPR. Methods: Patients suffering an out-of-hospital cardiac arrest in
A feedback neural approach to static communication routing in asymmetric networks is presented, where a mean field formulation of the Bellman-Ford method for the single unicast problem is used as a common platform for developing algorithms for multiple unicast, multicast and multiple multicast problems. The appealing locality and update philosophy of the Bellman-Ford algorithm is inherited. For al
The oxidation of Pd(111) leads to an incommensurate surface oxide, which was studied by the use of scanning tunneling microscopy, surface x-ray diffraction, high resolution core level spectroscopy, and density functional calculations. A combination of these methods reveals a two-dimensional structure having no resemblance to bulk oxides of Pd. Our study also demonstrates how the atomic arrangement
OBJECTIVE: To describe the long-term influence of meniscectomy on pain, functional limitations, and muscular performance. To assess the effects of radiographic osteoarthritis (OA), gender and age on these outcomes in patients with meniscectomy. DESIGN: 159 subjects (35 women), mean age 53 years, were examined 19 (17-22) years after open meniscectomy. Self-reported symptoms and function were assess
A photochemistry study on nitrous oxide making use of site-selective excitation of terminal nitrogen, central nitrogen, and oxygen 1s-->3pi excitations is presented. The resonant Auger decay which takes place following excitation can lead to dissociation of the N(2)O(+) ion. To elucidate the nuclear dynamics, energy-resolved Auger electrons were detected in coincidence with the ionic dissociation
Purpose: We aimed to investigate associations between serum levels of the advanced glycation endproduct methylglyoxal-derived hydroimidazolone (MG-H1) and retinopathy in a sample of patients with type 1 diabetes. Methods: We conducted a cross-sectional study in a Scandinavian ophthalmology outpatient clinic on 61 randomly selected patients with type 1 diabetes. Blood samples and retinal photograph
Urokinase plasminogen activator (uPA) is involved in the activation of different proteases which participate in the degradation of extracellular matrix, thereby enhancing the invasive capacity of tumour cells. uPA has been shown to be of prognostic importance in breast cancer. We have analysed uPA with a new luminometric immunoassay (LIA), applicable in cytosol samples routinely used for oestrogen
EU negotiations are characterized bythe coexistence of a bargaining and a problem-solving approach. The permanence of EU negotiations discourages tough bargaining behaviour, as does the prevalence of strong consensus norms. On the other hand, evidence exists of very confrontational behaviour that often leads to lowest common denominator solutions. We argue that the mode of negotiation to be found
