During 2012 - 2013 a study to evaluate conventional X-ray procedures and patient doses in Klintzi and Novozibkov areas of Bryansk region, Russia, was conducted. X-ray operation parameters included quality assurance of equipment, collection of procedure parameters and clinical practice evaluation. Effective doses were calculated for each selected procedure and dose distributions were established. 7
We report the use of multinodal acoustic trapping for high throughput and high capacity capturing of EV's (extracellular vesicles) for quantitative mass spectrometry analysis. The multinode trapping unit was shown to isolate sufficient amount of EV's from dilute biological samples (urine and cell culture supernatant) at flow rates of 500 ul/min within minutes, enabling EV proteome profiling. This
Cells of the exocrine pancreas produce digestive enzymes potentially harmful to the intestinal mucosa. Dopamine has been reported to protect against mucosal injury. In looking for the source of dopamine in the small intestine, we found that the duodenal juice contains high levels of dopamine and that the pancreas itself has a high dopamine [and dihydroxyphenylalanine (dopa)] content that does not
Medellivslängden ökar och är idag över 80 år i 34 av världens länder, jämfört med i 19 länder år 2005. Detta ärpositivt, men den åldrande befolkningens hälsa är också en samhällsutmaning inte minst för välfärdssystemen.Hälso- och sjukvården riskerar blir särskilt belastad med allt fler vårdsökande äldre. Yrkesgrupperna inom hälsoochsjukvården har dessutom en hög medelålder och är samtidigt bland d
Popular Abstract in Swedish Ett bröstmjölksprotein som dödar tumörceller Denna avhandling beskriver den tumörcell- och bakteriedödande effekten av ett proteinkomplex från bröstmjölk. Proteinkomplexet, en veckningsvariant av humant alfa-laktalbumin, inducerar apoptos (programmerad celldöd) i tumörceller och visar sig ha liknande effekter även mot bakterier. Amning förser inte bara barnet med optiHuman milk contains a vast array of bioactive molecules, with nutritional and protective functions. This thesis describes the effects of a human milk protein complex, MAL, on tumour cells and bacteria. During our studies on the anti-adhesive properties of human milk we observed that a milk fraction killed tumour cells. The morphology of the cells indicated apoptotic cell death and this was verifie
Solvents are commonly used in pharmaceutical and cosmetic formulations and sanitary products and cleansers. The uptake of solvent into the skin may change the molecular organization of skin lipids and proteins, which may in turn alter the protective skin barrier function. We herein examine the molecular effects of 10 different solvents on the outermost layer of skin, the stratum corneum (SC), usin
Aging of the hematopoietic stem cell compartment is believed to contribute to the onset of a variety of age-dependent blood cell pathophysiologies. Mechanistic drivers of hematopoietic stem cell (HSC) aging include DNA damage accumulation and induction of tumor suppressor pathways that combine to reduce the regenerative capacity of aged HSCs. Such mechanisms do not however account for the change i
Popular Abstract in Swedish En välfungerande andning med utbyte av syrgas och koldioxid mellan kroppen och omgivningen är en förutsättning för liv. För att detta gasutbyte ska fungera krävs bl. a. att ventilationen, dvs. in- och utflödet av luft i lungorna, står i balans med blodflödet genom lungorna. I lungorna tar blodet emot syrgas som behövs för att cellerna i kroppen ska fungera och samtidigtRespiration relies, among other things, on the balance between regional ventilation and perfusion in the lungs. There are many cardiopulmonary diseases, such as pulmonary embolism (PE), chronic obstructive pulmonary disease (COPD) and left heart failure (LHF), which can affect respiration negatively. The diagnosis of PE, COPD and LHF follows separate diagnostic pathways. However, the symptoms that
Encounters between patients in homecare and nursing students are cultural events where students, in principle, are in unknown territory. This study illuminated how nursing students recount (inter)actions in social relations in Danish homecare settings, illustrated by students with a self-appointed immigrant background. The study consisted of semi-structured interviews with eight nursing students.
The attitude of teachers towards students can vary substantially in relation to different factors, such as educational background, pedagogical training, teaching methods, etc. In this paper, we explore the impact of negative role-models on future teaching. In particular, past experiences of teachers as students as well as the contextual influence of other teachers on their future teaching has been
Popular Abstract in Swedish Spionen var under kalla kriget en gäckande gestalt som i egenskap av sin synliga osynlighet blev en orienteringspunkt för vardagliga fantasier. Han – för denna det kalla krigets emblematiska figur var oftast en han – blev i flera avseenden just en samtidens mittpunkt i vilken en tudelad världsbild synliggjordes. Mannen i mitten handlar om Spionen i svensk kallakrigskultThe aim of this thesis is to contribute to a broadening of perspectives on Cold War Sweden. It is a study not primarily of the explicit political events or debates, but of the everyday cultural narratives of the era. During the long 1950s, Swedish Cold War imagination was largely characterised by a determination to maintain total security in the response to the threats that loomed on all sides, an
This paper presents a model for corporate social responsibility (CSR) created to integrate human rights issues in sustainable tourism, through public-private partnerships between the industry, non-governmental organisations (NGOs)and international governmental organisations (IGOs). The experience with the model in practice is described in a case study presenting a voluntary code of conduct adopted
HAMLET (human alpha-lactalbumin made lethal to tumor cells) is a tumoricidal complex consisting of partially unfolded protein and fatty acid, and was first identified in casein fractions of human breast milk. The complex can be produced from its pure components through a modified chromatographic procedure where pre-applied oleic acid binds with partially-unfolded alpha-lactalbumin on the stationar
Popular Abstract in Swedish Streptococcus pyogenes (GAS) är en viktig sjukdomsframkallande bakterie som orsakar alltifrån lindriga infektioner som halsfluss (tonsillit) och svinkoppar (impetigo) till livshotande djupa infektioner som nekrotiserande fasceit eller ”Toxic shock syndrom”. På grund av det snabba sjukdomsförloppet i de livshotande infektionerna har streptokockerna fått beteckningen ”mörA distinguishing feature of Streptococcus pyogenes (GAS) is their ability to resist phagocytosis in whole human blood in the absence of type-specific antibodies, a property that is dependent on the expression of the surface associated M proteins. A common characteristic of M proteins is their interaction with a variety of host proteins including the complement regulatory protein factor H (FH) and
Popular Abstract in Swedish Vad arbetar en analytisk kemist med? Exempel på kemiska analyser är att en idrottsman ska dopingtestas eller att eventuella föroreningar i vattnet från en bäck ska bestämmas. Den analytiska kemistens problemställning är vanligtvis att identifiera (kvalitativ analys) och mäta upp (kvantitativ analys) innehållet i ett prov. Ofta är de intressanta ämneshalterna mycket lågaCapillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.
