The antitumour effect of applied high voltage exponential pulses was investigated on rats with subcutaneously implanted N32 brain tumours. Superficial tumours on the thigh were produced by the injection of 100 000 N32 glioma cells on Fischer-344 rats. Four weeks after inoculation, a solid tumour has grown to a size of about 1 cm located directly under the skin. Short electric high voltage pulses w

In order to establish the validity of in vitro determination of the proton magnetic resonance (MR) relaxation times T1 and T2 in brain tissue at increasing time delay after death or operative excision, 81 brain tissue samples from 23 pigs were analyzed repeatedly. These samples, representing cortex, caudate nucleus and white matter, were studied microscopically after MR measurements. The T1 values

Red cell distribution width (RDW) has been suggested to have a predictive potential for several cardiovascular diseases, but its association with abdominal aortic aneurysm (AAA) is unknown. We examined whether RDW is associated with the risk of AAA among 27,260 individuals from the population-based Malmö Diet and Cancer Study cohort. Data of baseline characteristics were collected during 1991–1996

Utgångspunkten för det här numret av Dragomanen är fritid och artiklarna behandlar ämnen som på ett eller annat vis kan sättas i relation till ordet: det rör sig om bröllop, strandliv, husdjur, fotboll, musik, alkohol, TV-drama, teater och förändringar i vardagen i samband med krig och pandemi. En majoritet av texterna diskuterar former av fritid i Turkiet, men även andra områden vid östra Medelha

The synthesis aims to lay the foundation for an improved understanding of the biophysical influence of land-use and land-cover changes on regional climate and terrestrial ecosystem change in Sweden, and to outline a roadmap for developing tools that support the formulation of policies and decision-making by policymakers, taking these potentially significant effects into account. The additional inf

In the Protestant tradition the trade and commerce that surrounded different aspects of Catholic spirituality was regarded as something relatively alien. In Protestant Sweden the critique towards these aspects of Catholicism became an essential component in the anti-Catholic rhetoric that was recurring during the latter nineteenth and the early twentieth century. From the perspective of Lutheran t

Beginning in December 2010, the Arab world was hit by huge anti-government revolutionary waves, popularly known as the Arab Spring. In Syria, the uprising did not take long to morph into a bloody war with international and regional powers wrestling for geopolitical influence and economic gain. The war has significantly changed Syria in terms of politics, economy, and culture. While the first two h

The current status of and motivation for the 4MOST survey strategy, as developed by the Consortium science team, are presented here. Key elements of the strategy are described, such as sky coverage, number of visits and total exposure times in different parts of the sky, and how to deal with different observing conditions. The task of organising the strategy is not simple, with many different surv

Objective A case-control study was conducted to assess seasonal influenza vaccine effectiveness (SIVE) during the 2015-2016 influenza season. Methods A study was performed in three departments in Lithuania between 1 December 2015 and 1 May 2016. Data on demographic and clinical characteristics including influenza vaccination status were collected from the patients recommended to receive the season

The external differences between the well‐documented S. scolytus and the little studied S. laevis are clarified with the help of SEM micrographs of the frons and abdomen of both sexes of the two species. The convex frons of both male and female S. scolytus is densely covered with short hairs. S. laevis males have a flat frons with long hairs in a pair of bundles, whereas the females have a convex

A difference in female pheromone production and male behavioral response has previously been found in two populations of the turnip moth, Agrotis segetum, originating from Sweden and Zimbabwe, respectively. In this study, we investigated the pheromone response of antennal lobe interneurons of males of the two populations by intracellular recordings, stimulating with single pheromone components and

A basic theoretical model that describes the effects of flow in and out of the imaging plane in nuclear magnetic resonance (NMR) images, obtained with the standard pulse sequences single spin echo, multiple spin echo, and inversion recovery, is presented. Theoretically calculated signal values are compared with experimental results obtained from single-slice images of a flow phantom for variable f

The biokinetics of inert lymphoscintigraphic agentsstrongly depends on their particle size. Different techniques for characterization of colloids are discussed. Experiments have been performed on eight different colloids. The particle size has been investigated with scanning electron microscopy. Activity distributions have been obtained with ultrafiltration and gel-column scanning technique. The c

A goal of the International Prophylaxis Study Group (IPSG) is to provide an accurate instrument to measure MRI-based disease severity of haemophilic arthropathy at various time points, so that longitudinal changes in disease severity can be identified to support decisions on treatment management. We review and discuss in this paper the evaluative purpose of the IPSG MRI scale in relation to its de

This paper is intended to discuss the optimization of camshaft efficiency; using the rolling bearing instead of the sliding bearing within the internal combustion engines. The advantages and disadvantages of employing this new method will be accordingly identified and determined in-order to open new windows to the vehicle manufacturing industry. Following the mentioned goal; a camshaft is designed

Due to the complexity of clinical breast cancer imaging systems, their validation and optimization are challenging tasks, which require both preclinical and clinical studies. This is particularly true for systems used in breast cancer screening due to the low prevalence of disease in a screening population. Validation for screening requires clinical trials involving very large numbers of volunteer
