Long-term effects of liming on net sulphur mineralization in coniferous forest 0 horizons were studied in three laboratory experiments by an open incubation technique, in which net sulphur mineralization was estimated from the accumulated SO42- leaching during the incubation period. Soil from two Swedish field experiments was used; Hasslov (56degrees24'N, 13degrees00'E) and Nordiden (64degrees21'N
Financial theory, access to deal flow, selection, and monitoring skills are used to explain syndication in venture capital firms in six European countries. In contrast with U.S. findings, portfolio management motives are more important for syndication than individual deal management motives. Risk sharing, portfolio diversification, and access to larger deals are more important than selection and m
The use of genetically modified animals in biomedical research has increased during recent years and its ethical aspects have been subject to academic discussion. In order to make this discussion more concrete, we analyzed applications submitted to animal ethics committees in Sweden in 2002. The aim was to investigate the researchers’ statements concerning the production and use of genetically mod
Two methods of quantifying fungal activity have been compared and correlated: isothermal calorimetry for measuring heat production and gas chromatography-tandem mass spectrometry (GC-MS/MS) for measuring ergosterol, a proxy for biomass. The measurements were made on four different fungi: Penicillium roqueforti, Cladosporiurn cladosporioides, Neopetromyces muricatus and the dry rot fungus Serpula l
Previous in vitro studies have implied that the Wnt-5a gene plays a role as a tumor suppressor. To explore the clinical relevance of this concept, 96 primary invasive breast carcinomas were stained with a novel anti-Wnt-5a antibody. Loss of Wnt-5a protein expression, evident in 44% of the invasive ductal carcinomas (n = 59), was significantly associated with higher histological grade (P = 0.01) an
Popular Abstract in Swedish Avhandlingen analyserar Guatemalas råvaruexport under perioden 1524-1945.In the integrated institutional-staples-‘vent for surplus’ approach, the opening of trade occurs because of initial demand. Once demand is determined, competitiveness is a function of transportation costs, entrepreneurship, capital, land and labour costs, as well as the role played by the State. When all these factors promote competitiveness within an institutional framework that decreased transac
Knee kinematics after anterior cruciate ligament (ACL) reconstruction is of interest in studies evaluating the effect of training programs. Many studies have addressed knee flexion/extension but not valgus/varus movements. Considering that joint stability is a major concern in ACL reconstruction surgery, movements occurring in the frontal plane of the knee also deserve attention. Knee extensor tor
OBJECTIVES: During the endovascular repair of abdominal aortic aneurysms (AAAs), effective anchoring of the stent-graft is difficult in the presence of a short infrarenal aneurysm neck. The aim of this study was to investigate renal artery patency and renal function after deployment of graft anchoring stents across the renal arteries. DESIGN: Retrospective open study. PATIENTS: Twenty-five renal a
Nocturia is an increasingly prevalent and bothersome urinary symptom associated with considerable impact and morbidity in later life. Nocturnal frequency is associate with a number of underlying pathologies, both related and unrelated to the lower urinary tract. Following careful assessment, diagnosis and management, the condition is amenable to amelioration, if not complete cure in the majority o
The effect of the total amount of work hours and the benefits of a shortening is frequently debated, but very little data is available. The present study compared a group (N = 41) that obtained a 9 h reduction of the working week (to a 6 h day) with a comparison group (N = 22) that retained normal work hours. Both groups were constituted of mainly female health care and day care nursery personnel.
Moraxella catarrhalis ubiquitous surface proteins A1 and A2 (UspA1/A2) interfere with the classical pathway of the complement system by binding C4b-binding protein. In this study we demonstrate that M. catarrhalis UspA1 and A2 noncovalently and in a dose-dependent manner bind both the third component of complement (C3) from EDTA-treated serum and methylamine-treated C3. In contrast, related Moraxe
The age and sex-specific incidence and prevalence of vertebral compression fractures were compared between the 1950s and 1980s in an urban population. In women over 80 years of age the incidence of symptomatic vertebral fractures has increased approximately four times; in elderly men even more. Mainly, low-energy trauma has caused these fractures. Thus, one clinical manifestation of osteoporosis--
The relevance of particle mass, surface area or number concentration as risk indicators for health effects in non-industrial buildings has been assessed by a European interdisciplinary group of researchers (called EUROPART) by reviewing papers identified in Medline, Toxline, and OSH. Studies dealing with dermal effects or cancer or specifically addressing environmental tobacco smoke, house dust-mi
The effect and possible mechanisms of action of aminoguanidine (a preferential iNOS inhibitor) has been studied on cardiovascular damages and overproduction of reactive nitrogen species in streptozotocin-induced diabetic rats. MATERIALS AND METHODS: 40 rats were divided into five groups (control and diabetic, with or without aminoguanidine treatment, diabetic with insulin treatment) and oxidative
