- In order to grow, tumors need to induce supportive alterations in the tumor-bearing organ, by us named tumor instructed normal tissue (TINT) changes. We now examined if the nature and magnitude of these responses were related to tumor size and aggressiveness. Three different Dunning rat prostate tumor cells were implanted into the prostate of immune-competent rats; 1) fast growing and metastatic MatLyLu tumor cells 2) fast growing and poorly metastatic AT-1 tumor cells, and 3) slow growing and non-metastatic G tumor cells. All tumor types induced increases in macrophage, mast cell and vascular densities and in vascular cell-proliferation in the tumor-bearing prostate lobe compared to controls. These increases occurred in parallel with tumor growth. The most pronounced and rapid responses were seen in the prostate tissue surrounding MatLyLu tumors. They were, also when small, particularly effective in attracting macrophages and stimulating growth of not only micro-vessels but also small arteries and veins compared to the less aggressive AT-1 and G tumors. The nature and magnitude of tumor-induced changes in the tumor-bearing organ are related to tumor size but also to tumor aggressiveness. These findings, supported by previous observation in patient samples, suggest that one additional way to evaluate prostate tumor aggressiveness could be to monitor its effect on adjacent tissues.

Mälsåker Revisited: Museum och Iscensättning. : Kungl Konsthögskolan. Restaureringskonst 2015-2016
- 2016
-
Rapport (populärvet., debatt m.m.)abstract
- Rapporten redovisar arbeten från kursen Restaureringskonst på Konsthögskolan som under läsåret 2015-2016 har arbetat med tema Museum och Iscensättning. Hur kulturmiljöer påverkas när de blir museum, hur man restaurerar för museum, hur man bevarar och utvecklar en plats för kunskapsutbyte, bildning och upplevelser. Mälsåkers slott, utanför Mariefred, förvaltat av Statens Fastighetsverk, var studieobjekt för 20 studenter, (yrkesverksamma arkitekter, antikvarier, ingenjörer, konservatorer m fl) där utbildningens olika studiemoment som uppmätning, inventering, dokumentation har tillämpats. Fältarbetet har följts av studier i historik, kulturhistorisk värdering och analyser som gett visioner och gestaltningsförslag på ny verksamhet i slottet. Rapporten presenterar förslagen, med text, skisser, foton och ritningar. Fyra olika typer av museum med varierande grad av åtgärder, förändringar och utveckling av slottet. Restaureringsexperiment redovisas utifrån traditionella och digitala dokumentationsmetoder. Dessutom finns arbeten om barockens ljus, bladguld, brandskydd, pod-radio, kraftstation, engelska parken, dekorationsmålade tak, Gustavianum, Julius Kronbergs ateljé och barockträdgård m m. Förslagen visar att det är möjligt att transformera Mälsåkers barockslott till ett museum av idag med bibehållen historik och synliga tidslager.

Divergence within and among Seaweed Siblings (Fucus vesiculosus and F. radicans) in the Baltic Sea
- 2016

Ingår i: Plos One. - : Public Library of Science (PLoS). - 1932-6203. ; 11:8

Tidskriftsartikel (refereegranskat)abstract
- Closely related taxa provide significant case studies for understanding evolution of new species but may simultaneously challenge species identification and definition. In the Baltic Sea, two dominant and perennial brown algae share a very recent ancestry. Fucus vesiculosus invaded this recently formed postglacial sea 8000 years ago and shortly thereafter Fucus radicans diverged from this lineage as an endemic species. In the Baltic Sea both species reproduce sexually but also recruit fully fertile new individuals by asexual fragmentation. Earlier studies have shown local differences in morphology and genetics between the two taxa in the northern and western Bothnian Sea, and around the island of Saaremaa in Estonia, but geographic patterns seemin conflict with a single origin of F. radicans. To investigate the relationship between northern and Estonian distributions, we analysed the genetic variation using 9 microsatellite loci in populations from eastern Bothnian Sea, Archipelago Sea and the Gulf of Finland. These populations are located in between earlier studied populations. However, instead of bridging the disparate genetic gap between N-W Bothnian Sea and Estonia, as expected from a simple isolation-by-distance model, the new populations substantially increased overall genetic diversity and showed to be strongly divergent from the two earlier analysed regions, showing signs of additional distinct populations. Contrasting earlier findings of increased asexual recruitment in low salinity in the Bothnian Sea, we found high levels of sexual reproduction in some of the Gulf of Finland populations that inhabit extremely low salinity. The new data generated in this study supports the earlier conclusion of two reproductively isolated but very closely related species. However, the new results also add considerable genetic and morphological complexity within species. This makes species separation at geographic scales more demanding and suggests a need for more comprehensive approaches to further disentangle the intriguing relationship and history of the Baltic Sea fucoids.

- Objective: This qualitative, longitudinal, descriptive study aimed to understand the lived experience of enacting agency, and to describe the phenomenon of agency and the meaning structure of the phenomenon during the year after a stroke. Agency is defined as making things happen in everyday life through one's actions. Methods: This study followed six persons (three men and three women, ages 63 to 89), interviewed on four separate occasions. Interview data were analysed using the Empirical Phenomenological Psychological method. Results: The main findings showed that the participants experienced enacting agency in their everyday lives after stroke as negotiating different characteristics over a span of time, a range of difficulty, and in a number of activities, making these negotiations complex. The four characteristics described how the participants made things happen in their everyday lives through managing their disrupted bodies, taking into account their past and envisioning their futures, dealing with the world outside themselves, and negotiating through internal dialogues. Conclusions: This empirical evidence regarding negotiations challenges traditional definitions of agency and a new definition of agency is proposed. Understanding clients' complex negotiations and offering innovative solutions to train in real-life situations may help in the process of enabling occupations after a stroke.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To explore and describe persons with stroke and their caregivers' restrictions in participation in everyday occupations, i.e. occupational gaps, 3-6 months post-stroke, in relation to life satisfaction, combined life satisfaction, caregiver burden, perceived impact of stroke, and activities of daily living. Design: Cross-sectional study. Subjects: Persons with stroke and their caregivers (105 dyads). Methods: The Occupational Gaps Questionnaire, Life Satisfaction Checklist, Caregiver Burden Scale, Stroke Impact Scale and Barthel Index were used. Correlations were analysed with Spearman's rank, and regression analyses used life satisfaction as the dependent variable. Results: At least one person in 86% of the dyads perceived restrictions in participation, with the most common gap in travelling for pleasure. Correlations were low between the numbers of occupational gaps and life satisfaction (R=-0.33, R=-0.31); however, life satisfaction accounted for occupational gaps both for persons with stroke and for caregivers. A greater number of occupational gaps were perceived in the dyads with combined low levels of life satisfaction compared with those with combined high levels of life satisfaction. Conclusion: Participation in everyday occupations is related to life satisfaction even for caregivers of persons with stroke. The results of this study add to our knowledge about the stroke-caregiver dyad and will help to inform family-centred approaches within stroke rehabilitation.

Biorelevant intrinsic dissolution profiling in early drug development : Fundamental, methodological, and industrial aspects
- 2019
-
Ingår i: European journal of pharmaceutics and biopharmaceutics. - : Elsevier. - 0939-6411 .- 1873-3441. ; 139, s. 101-114

Forskningsöversikt (refereegranskat)abstract
- Intrinsic dissolution rate (IDR) is the surface specific dissolution rate of a drug. In early drug development, this property (among other parameters) is measured in order to compare different polymorphs and salt forms, guide formulation decisions, and to provide a quality marker of the active pharmaceutical ingredient (API) during production. In this review, an update on different methods and small-scale techniques that have recently evolved for determination of IDR is provided. The importance of biorelevant media and the hydrodynamic conditions of dissolution are also discussed. Different preparation techniques for samples are presented with a focus on disc, particle- and crystal-based methods. A number of small-scale techniques are then described in detail, and their applicability domains are identified. Finally, an updated industrial perspective is provided about IDR's place in the early drug development process.

Nationalmuseum i offentlighetens ljus : framväxten av tillfälliga utställningar 1866-1966
- 2018

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this study is to investigate the emergence of temporary exhibitions at the Nationalmuseum of Sweden 1866–1966. My aim is to discuss and place the exhibitions in the complex ongoing tension between the role of the museum as a scientific and an educative public institution, and in relation to the permanent collection. This I have called the museum dilemma. The dissertation is divided in three main chapters put in a chronological order 1866–1913, 1914–1939 and 1940–1966. I have found that during the 1866–1913 period many minor temporary exhibitions were arranged. It seems to have been a practice of coincidences rather than strategic art historical considerations. There were not many exhibitions focusing on art historical narratives. This situation reflects that the main reasons for arranging temporary exhibitions were to complement the museum collection or to present interesting art objects normally hidden from the public view.When the term “temporary exhibition” was established in the late 19th century a tension between the exhibitions and the permanent collection was established. The temporary exhibitions were associated with variety and flexibility while the permanent collection indicated a static art historical narrative.The 1914–1939 period was very socially inclined. There are many examples of exhibitions that openly supported national values and the ongoing democracy development and the exhibition practice developed in dialog with the museum´s collection. The concept “bringing art alive” was frequently used. The museum collections were talked about as dead material, the museum was called a morgue. During the Second World War, the collections were evacuated from the museum building and an innovative period began. A focus on art history dominates the more elaborated exhibition practice during 1939–1966 period, so called “epoch exhibitions”. They invited to innovative actions, technologies as reconstructions of historical exhibitions, mixed materials and rehanging during the exhibition period. Principles as flexibility and variation were prominent. Another common denominator was the scientific focus and the idea that the exhibition is both an experience and a source of knowledge. Even though half a century has passed I argue that the results I have found can be related to the museum practice of today. The tendency today is that temporary exhibitions functions as role models for museums, when re-organizing the permanent collections. The effect of this development is that the categories temporary exhibitions and permanent collection melt together. In that sense, I would also suggest that the term temporary exhibition should be replaced. Special exhibition seems to be a more appropriate term for the museums of today.
