- OBJECTIVES: In 2006, a new variant of Chlamydia trachomatis (nvCT) was discovered in Sweden. It has a deletion in the plasmid resulting in failed detection by the single target systems from Abbott and Roche used at that time, whereas the third system used, from Becton Dickinson (BD), detects nvCT. The proportion of nvCT was initially up to 65% in counties using Abbott/Roche systems. This study analysed the proportion of nvCT from 2007 to 2015 in four selected counties and its impact on chlamydia-associated complications.METHODS: C. trachomatis-positive specimens collected from 2007 to 2015 were analysed by a specific PCR to identify nvCT cases. Genotyping was performed by multilocus sequence typing (MLST) and ompA sequencing. Ectopic pregnancy and pelvic inflammatory disease records were extracted from the national registers.RESULTS: In total, 5101 C. trachomatis-positive samples were analysed. The nvCT proportion significantly decreased in the two counties using Roche systems, from 56% in 2007 to 6.5% in 2015 (p<0.001). In the two counties using BD systems, a decrease was also seen, from 19% in 2007 to 5.2% in 2015 (p<0.001). Fifteen nvCT cases from 2015 and 102 cases from 2006 to 2009 had identical MLST profiles. Counties using Roche/Abbott systems showed higher mean rates of ectopic pregnancy and pelvic inflammatory disease compared with counties using BD systems.CONCLUSIONS: The nvCT proportion has decreased in all counties and converged to a low prevalence irrespective of previous rates. Genotyping showed that nvCT is clonal and genetically stable. Failing detection only marginally affected complication rates.

Tidskriftsartikel (refereegranskat)abstract
- Social exclusion is complex and dynamic, and it leads to the non-realization of social, economic, political or cultural rights or participation within a society. This critical review takes stock of the literature on exclusion of social relations. Social relations are defined as comprising social resources, social connections and social networks. An evidence review group undertook a critical review which integrates, interprets and synthesizes information across studies to develop a conceptual model of exclusion from social relations. The resulting model is a subjective interpretation of the literature and is intended to be the starting point for further evaluations. The conceptual model identifies individual risks for exclusion from social relations (personal attributes, biological and neurological risk, retirement, socio-economic status, exclusion from material resources and migration). It incorporates the evaluation of social relations, and the influence of psychosocial resources and socio-emotional processes, sociocultural, social-structural, environmental and policy contextual influences on exclusion from social relations. It includes distal outcomes of exclusion from social relations, that is, individual well-being, health and functioning, social opportunities and social cohesion. The dynamic relationships between elements of the model are also reported. We conclude that the model provides a subjective interpretation of the data and an excellent starting point for further phases of conceptual development and systematic evaluation(s). Future research needs to consider the use of sophisticated analytical tools and an interdisciplinary approach in order to understand the underlying biological and ecopsychosocial associations that contribute to individual and dynamic differences in the experience of exclusion from social relations.

Samlingsverk (redaktörskap) (refereegranskat)abstract
- The conference Codex and Code: Aesthetics, Language and Politics in an Age of Digital Media (NorLit 2009)was held at the Royal Institute of Technology (KTH) in Stockholm, August 6–9, 2009. The conference was organized by the Nordic Association for Comparative Literature (NorLit); the Department of Culture and Communication, Linköping University; the School of Computer Science and Communication, Royal Institute of Technology (KTH); the Department of Comparative Literature, Stockholm University; the Department of Culture and Communication, Södertörn University College; and the Department of Comparative Literature, Uppsala University. The aim of the conference was to develop the study of Comparative Literature through Nordic collaboration both in its own discipline and in Modern Language and Cultural studies. As the title for the conference suggests, the principal question for the conference was the challenge that the study of literature encounters in an age of digitalization and globalization. It was our aim to encourage discussion of how literary studies respond to the ongoing changes in media and technology, politics and economy. Many have argued that the Humanities currently are in a state of crisis. We believe that the discipline seldom has found itself in such an interesting and fruitful historical moment. Several of these questions have surfaced during earlier media system changes, in particular during Romanticism and Modernism, which provided the conference with an historical frame. The conference Codex and Code also addressed questions of authenticity and originality, identity and gender, literary genres and reading practices, media and materiality, culture and popular culture, language and history, world literature, work aesthetics, translations, and canon formation. The conference Codex and Code wanted to stimulate interdisciplinary scholarly research of the literary in a broad sense. The conference was open to scholars in Comparative Literature and in Classical and Modern Languages, Aesthetics, Media and Communication studies, Film and Theatre studies, Philosophy and adjacent disciplines. The conference was organized around a number of thematic sessions in which researchers and scholars presented and discussed papers. The conference has received generous financial support from the Bank of Sweden Tercentenary Foundation, Magnus Bergwall foundation, Granholms foundation, Linköping University, School of Computer Science and Communication, Royal Institute of Technology, Svenska litteratursällskapet; the Swedish Academy, Swedish Science Council, and Vitterhetsakademien.

Digital media and the transnationalization of protests
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Recent developments in communications technology have transformed how social movements might mobilize, and how they can organize their activities. This thesis explores some of the geographical consequences of the use of digital media for political activism. It does this by focusing on the transnationalization of protests. The aim is to analyse how movements with different organizational structures and political scopes are affected by their use of digital media. This is done with a specific focus on how digital media use influences or enables transnational modes of organization and activism. The thesis comprises four different case studies where each study examines a social movement with a specific organizational structure. There are, however, also important similarities between the movements. In each study, somewhat different perspectives and methodological approaches are used. Some of the methods used are semi-structured interviews, content analysis of written data (retrieved from Facebook as well as Twitter), and social network analysis.The analysis indicates that digital media do have a role in the transnationalization of protest. This role, however, differs depending on what type of social movement one studies. The organizational structure of social movements, together with their specific forms of digital media use, influences how the transnationalization of protests and movements is articulated and formed. In cases where a social movement has a hierarchical organizational structure, there is less transnationalization, whereas in social movements with a more non-hierarchical organizational structure one sees more transnationalization. The thesis concludes that the transnationalization of protests is affected by social movements’ organizational structure. The more decentralized the social movement, the more vibrant the transnational public. In order to explain how transnational social movements, using digital media, can emerge in cases where geographical distances might make such coalitions unlikely, the thesis introduces the notion of affectual proximity. This concept helps us understand how transnational social movements, connecting actors from all over the world, can emerge through digital media.

Cooperative Transportation Planning and Cost Allocation
- 2015
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- A freight forwarder may consolidate its goods transportations in order to achieve a more efficient operation. When goods transportations are consolidated, they may reduce operational costs, e.g. labor and fuel. This can be further improved if a number of freight forwarders cooperate and consolidate their collective goods transportations, i.e. it is a cooperation between competitors, a coopetition. In order to maintain the cooperation, a suitable business model, in which fair cost allocations plays an important role is essential. The potential by cooperating is not exclusive to freight forwarders, but in fact, any type of goods transportation planning may benefit from cooperation. In this thesis, cooperative game theory is used as an academic tool to study cooperation between stakeholders in different transportation planning applications. Cooperative game theory defines a number of criteria for fair cost allocations.In Paper 1, the role of the municipality as an enabler of a cooperation between fictitious freight forwarders in an urban area, is studied. In this case, the municipality acts as a stakeholder with unusual characteristics. It is shown that a stable cooperation can be achieved if the municipality is willing to carry some of the cost. This cost is specified and discussed in Paper 1. The results of Paper 2 contribute to game theory by introducing a further development of a cost allocation method. Some small numerical examples are presented in order to illustrate the resulting changes. In Paper 3, the process of establishing a cooperation is studied, where the stakeholders, in this case forest companies, join the cooperation sequentially. Who will join and in what order, is not predetermined. It is shown that a stable cooperation can be achieved despite the uncertainty. This is done by using the cost allocation methods presented.

Cost allocation methods in cooperative transportation planning
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Transportation, together with transportation planning for goods, provides good conditions for economic growth and is a natural part of modern society. However, transportation has negative side effects, including emissions and traffic congestion. A freight forwarder may consolidate shippers’ goods in order to reduce some of the negative side effects, thus reducing emissions and/or congestion as well as operational costs. The negative side effects as well as operational costs can be further reduced if a number of freight forwarders cooperate and consolidate their collective goods flows. Consolidation refers to the process of merging a number of the freight forwarders’ shipments of goods into a single shipment. In this case, the freight forwarders are cooperating with competitors (the other freight forwarders).Fair cost allocations are important for establishing and maintaining cost-efficient cooperation among competing stakeholders. Cooperative game theory defines a number of criteria for fair cost allocations and the problem associated with the decision process for allocating costs is referred to as the cost allocation problem. In this thesis, cooperative game theory is used as an academic tool to study cooperation among stakeholders in two transportation planning applications, namely 1) the distribution of goods bound for urban areas and 2) the transportation of wood between harvest areas and industries.In transportation planning application 1, there is a cooperation among a number of freight forwarders and a municipality. Freight forwarders’ goods bound for an urban area are consolidated at a facility located just outside the urban area. In this thesis, operational costs for distributing the goods are assessed by solving vehicle routing problems. Common methods from cooperative game theory are used for allocating the operational costs among the freight forwarders and the municipality. In transportation planning application 2, forest companies cooperate in terms of the supply and transportation of common resources, or more specifically, different types of wood. Each forest company has harvest areas and industries to which the wood is transported. The resources may be bartered, that is, the forest companies may transport wood from each other’s harvest areas.In the cooperative game theory literature, the stakeholders are often treated equally in the context of transportation planning. However, there seems to be a lack of studies on cooperations where at least one stakeholder differs from the other stakeholders in some fundamental way, for instance, as an initiator or an enabler of the cooperation. Such cooperations are considered in this thesis. The municipality and one of the forest companies are considered to be the initiators in their respective applications.Five papers are appended to this thesis and the overall aim is to contribute to the research into cooperative transportation planning by using concepts from cooperative game theory to develop methods for allocating costs among cooperating stakeholders. The purpose of this thesis is to provide decision support for planners in the decisionmaking process of transportation planning to establish cost-efficient and stable cooperations.Some of the main outcomes of this thesis are viable and practical methods that could be used in real-life situations to allocate costs among cooperating stakeholders, as well as support for decisionmakers who are concerned with transportation planning. This is done by demonstrating the potential of cooperation, such as cost reduction, and by suggesting how costs can be allocated fairly in the transportation planning applications considered. Lastly, a contribution to cooperative game theory is provided; the introduction of a development of the equal profit method for allocating costs. The proposed version is the equal profit method with lexicography, which, in contrast to the former, guarantees to yield at most one solution to any cost allocation problem. Lexicography is used to rank potential cost allocations and the unambiguously best cost allocation is chosen.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The photochemical coupling of fullerene molecules into covalently connected oligomeric or polymeric structures can result in drastically lowered solubility in common solvents with retained semiconductor properties. Here, we exploit this combination of properties for the utilization of fullerenes as a negative photoresist material with electronic functionality. Specifically, we develop an easily tunable exposure system, essentially comprising a laser and a computer-controlled spatial light modulator (SLM) featuring >8 million independently controlled pixels, for the spatially selective photochemical transformation of nanometer-thin C60 fullerene films. With a carefully designed laser-SLM-exposure/solvent-development cycle, we are able to realize well-resolved two-dimensional hexagonal or square patterns of circular C60 microdots with a center-to-center distance of 1–5 μm and a maximum thickness of 20–35 nm over several square-millimeter-sized areas on a substrate. The functionality of such a hexagonal C60 pattern was demonstrated by its inclusion in between the transparent electrode and the active material in a light-emitting electrochemical cell, which featured an enhanced light output by >50% in comparison to a reference device void of the patterned C60 layer.

Tidskriftsartikel (refereegranskat)abstract
- To evaluate clinical performance of a new automated cell-free (cf)DNA assay in maternal plasma screening for trisomies 21, 18, and 13, and to determine fetal sex.Maternal plasma samples from 1200 singleton pregnancies were analyzed with a new non-sequencing cfDNA method, which is based on imaging and counting specific chromosome targets. Reference outcomes were determined by either cytogenetic testing, of amniotic fluid or chorionic villi, or clinical examination of neonates.The samples examined included 158 fetal aneuploidies. Sensitivity was 100% (112/112) for trisomy 21, 89% (32/36) for trisomy 18, and 100% (10/10) for trisomy 13. The respective specificities were 100%, 99.5%, and 99.9%. There were five first pass failures (0.4%), all in unaffected pregnancies. Sex classification was performed on 979 of the samples and 99.6% (975/979) provided a concordant result.The new automated cfDNA assay has high sensitivity and specificity for trisomies 21, 18, and 13 and accurate classification of fetal sex, while maintaining a low failure rate. The study demonstrated that cfDNA testing can be simplified and automated to reduce cost and thereby enabling wider population-based screening.

New ways of collecting individual travel information : Evaluation of data collection and recruitment methods
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The overall purpose of the project is to conduct a demonstration study that shows how two data collection methods that have been developed to collect travel survey data perform in the field, and how they perform compared with traditional TS (i.e., postal questionnaires and/or telephone interviews). The project is also intended to provide a better understanding of the ways in which different recruitment methods of respondents can be used so that future TS can be more cost effective.The two collection methods tested consist of a mobile app and an online questionnaire with a map to assist the respondents to identify travel destinations. Three recruitment methods were used, i.e., recruitment via random sampling, a web panel, and crowdsourcing. The portion of the random sample that received an online questionnaire was divided into two groups. Half the group was given no incentive, while the other half received a gift card worth SEK 100 after answering the questioner. Those who were recruited via a web panel and were to use the mobile app were rewarded in the form of a gift card worth SEK 100 if, at minimum, they made corrections to trips made on one day registered in the mobile app. A nonresponse analysis was performed of the random sample for both the online questionnaire and the mobile app. Cost estimates for each collection method and recruitment method were also performed, as were uncertainty estimates.Overall, the study shows that the mobile app registered significantly more trips per respondent than did the online questionnaire, while the distances travelled were comparable. There are several possible interpretations of this. One is that people who responded to the online questionnaire either forget about and/or combined short trips (particularly trips made for the purposes of leisure or shopping, and using the travel modes walking and car). One presumable explanation for this is that it is easier to confirm/correct the trips that the mobile app suggests than it is to recall and enter all trips in an online questionnaire. Another possible interpretation is that people responding to different data collection methods have different travel patterns. Yet another explanation is connected to technique issues regarding the different data collection methods.

Nya sätt att samla in individuell resvaneinformation : Utvärdering av insamlings- och rekryteringsmetoder
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Inom samverkansprogrammet Nästa generations resor och transporter, som Trafikanalys är huvudansvarig för, har man identifierat ett behov av att finna och utveckla nya lösningar för resvaneundersökningar (RVU:er). Bakgrunden till detta är bland annat sjunkande svarsfrekvenser med dagens metoder, vilket skulle kunna ge problem med representativiteten. Det anses som mycket angeläget att utveckla nya metoder för datainsamling för framtidens RVU:er, både på kort och lång sikt.Det övergripande syftet med projektet är att göra en demonstrationsstudie som visar hur två datainsamlingsmetoder som har utvecklats för att samla in resevaneundersökningsdata presterar i fält, samt hur de presterar jämfört med ”traditionell” RVU (postal enkät och/eller telefonintervjuer). Projektet syftar också till att få bättre förståelse för hur olika rekryteringsmetoder kan användas för att framtida RVU:er ska kunna bli mer kostnadseffektiva. De två insamlingsmetoder som testats är webbenkät med karta och mobilapp. Tre rekryteringsmetoder har använts och dessa är rekrytering via slumpmässigt urval, webbpanel och crowdsourcing.

- During the last ten years, the inclusion of education in health information systems has assumed an important role in graduate programs for health professionals. More recently, attention has focused on undergraduate programs. Throughout the world schools of nursing, organisations and associations are addressing the issue of educational offerings in nursing informatics. This paper reports on the status of nursing informatics at undergraduate level. Nurse academics from Gavle and Lund in Sweden, and from Melbourne and Sydney in Australia, took part in a survey of the respective nursing courses. The purpose of the study was to identify and describe examples of types of nursing informatics courses in Australia and Sweden A convenient sample of academics were approached and interviewed The results of the survey illustrate, in the schools surveyed, the slow emergence of nursing informatics into nursing curricula.

Tidskriftsartikel (refereegranskat)abstract
- This overview of four evidence maps is based on systematic reviews of assessment and interventions in social work practice. The aim was to investigate the evidence and evidence gaps within four important areas for social work research and practice. Descriptive data on search strategies and domains were collected from four evidence maps, on Social Assistance, Substance Dependence, Care for older adults respectively for persons with disabilities. The scientific quality and scientific evidence were assessed. Key findings were summarised by analyzing and discussing common and specific elements in the evidence maps. The overview was undertaken in close collaboration between researchers with expertise in the field and a government agency. The overview identified both evidence and evidence gaps with respect to effects and experiences of interventions and assessment methods in four evidence maps. Evidence maps provide a comprehensive picture of the state of social services research and can thereby be of use to both researchers and practitioners, and in the production of evidence based social work.

Phycoremediation of heavy metals in ashes
- 2014
-
Ingår i: Chalmers Life Science Area of Advance Meeting, May 5, Göteborg.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A growing problem in today’s society is the increasing amount of ash from the production of electricity and heat. Ash contains heavy metals that may be harmful to the environment. By using algae as ion exchangers, the ashes can be purified from certain heavy metals before deposit and its environmental impact is decreased [1]. Algal cell wall contains functional groups, such as amino-, carboxyl-, hydroxyl- and suphate groups, to which the various metal ions can bind bind [3]. An ion exchange of bound metal ions toward heavy metal ions can occur when the cell wall comes in contact with, for example, leachate from the ashes [1]. The process of using algae for environmental remediation is called phycoremediation.Within this project, we study the potential of microalgae for remediating ash from heavy metals, by measuring the metal binding capacity by three phytoplankton species: Chlorella salina, Dunaliella salina and Scendesmus obliquus. The heavy metals assayed are divalent ions of mercury (Hg), cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn). The effect of pH has been investigated as well as total binding over time. To apply the method on a more authentic situation, the binding of metals from combustion ash was investigated.

Utvärdering av SI-verksamheten vid Lunds universitet 2022/23
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Enkelt uttryckt är Samverkansinlärning (SI) en studiecirkel kopplat till en utmanande kurs. SI leds av en senior student som utformar läraktiviteter där studenterna arbetar i grupper med att förklara och förtydliga svårt kursmaterial. Målsättningen med SI, förutom förbättrade prestationer i den aktuella kursen, är att studenterna skall utveckla goda studiestrategier och bli mer självständiga i sitt lärande. Denna rapport behandlar SI-verksamheten vid Lunds universitet under läsåret 2022/23. Målsättningen är att läsaren skall få en god bild av hur SI bedrivs vid lärosätet och hur insatsen upplevs av deltagare och studentledare. Rapporten bygger dels på kvantitativa data – SI-närvaro, samt närvaron kopplat till studenternas prestationer i SI-stödda kurser. Och dels på kvalitativa data från enkäter till deltagare och SI-ledare, dels information frän metodhandledare och SI-koordinatorer. Under läsåret 2022/23 kompletterades undervisningen i 204 kurstillfällen av SI där totalt 266 studentledare ledde SI-pass. 5200 studenter vid universitetet deltog på passen under läsåret. Medelnärvaron var 23 % och 53% av studenter med tillgång till SI provade på att besöka åtminstone ett pass. Dessa siffror betyder att SI-verksamheten vid Lunds universitet är en av de största vid lärosäten i Europa (SI finns på 75+ högre lärosäten i Europa). SI-verksamheten följer också grundläggande SI-principer på ett bra sätt enligt deltagarna. Exempelvis på så sätt att deltagarna har ett stort inflytande över agendan på SI-passen och att arbetet med att förstå utmanande kursmaterial bedrivs genom arbete och diskussion i grupp. SI-ledaren ser till att arbetet gårframåt genom att ställa frågor och uppmuntrar deltagarna att dela med sig av sina kunskaper till varandra.Studenternas drivkraft att gå på SI-passen är i huvudsak meningsorienterad genom att de vill få en bättre förståelse av ämnet och för att det är roligt att diskutera kursinnehåll med kurskamrater. Vad ger då deltagande på SI för närvarande studenter? Jämförelser av närvaro på SI och genomströmning på SI-stödd kurs antyder att chanserna att klara kursen vid ordinarie examination(er) ökar med ökad SI-närvaro. Deltagande studenter upplever dessutom i stor utsträckning att SI leder till att de bättre förstår vad som förväntas av dem i kursen, är ett effektivt stöd att ta sig fram i kursen, ökar intresset för ämnet och ger dem en djupare förståelse av kursinnehållet. Dessutom anser en stor andel av deltagarna att de utvecklar generella färdigheter såsom problemlösning, kritiskt tänkande, lagarbete och presentation av akademiskt material införandra. En betydande del av SI-deltagarna anger att de åtminstone till viss del utvecklar sitt sätt att studera och förbättrar sitt akademiska självförtroende. Lite mer än en fjärdedel av de svarande på enkäten anser att SI varit viktigt för att skaffa studiekamrater, vilket kan vara mycket betydelsefullt för att känna tillhörighet inom akademien och ge ytterligare motivation till fortsatta högre studier.De dominerande svarsteman på öppna enkätfrågor rörande vad som är bäst med SI samt vad som skiljer SI-pass från ordinarie undervisning är desamma för bägge frågorna. Det handlar om att deltagarna uppskattar diskussionen/samarbetet samt atmosfären och arbetsmiljön på passen. Vidare gillar studenterna fokus på djupare förståelse av kursinnehållet. På frågan vad man tycker kan förbättras med SI-passen anser en del av deltagarna att strukturen på passet ibland kan vara tydligare och att arbetet under passen ibland kan kännas ineffektivt.Det är roligt att konstatera att de allra flesta SI-ledarna trivs i sin roll, känner sig nöjda med sitt jobb och upplever att de gör skillnad för sina deltagare, baserat på deras enkätsvar. Dessutom utvecklar de i hög grad i olika färdigheter som kommunikation, grupphantering och ledarskap.

Tidskriftsartikel (refereegranskat)abstract
- Vulvar squamous cell carcinoma (VSCC) is the fourth most common gynecological cancer. Based on etiology VSCC is divided into two subtypes; one related to high-risk human papilloma virus (HPV) and one HPV negative. The two subtypes are proposed to develop via separate intracellular signaling pathways. We investigated a suggested link between HPV infection and relapse risk in VSCC through in-depth protein profiling of 14 VSCC tumor specimens. The tumor proteomes were analyzed by liquid-chromatography tandem mass spectrometry. Relative protein quantification was performed by 8-plex isobaric tags for relative and absolute quantification. Labeled peptides were fractionated by high-resolution isoelectric focusing prior to liquid-chromatography tandem mass spectrometry to reduce sample complexity. In total, 1579 proteins were regarded as accurately quantified and analyzed further. For classification of clinical groups, data analysis was performed by comparing protein level differences between tumors defined by HPV and/or relapse status. Further, we performed a biological analysis on individual tumor proteomes by matching data to known biological pathways. We here present a novel analysis approach that combines pathway alteration data on individual tumor level with multivariate statistics for HPV and relapse status comparisons. Four proteins (signal transducer and activator of transcription-1, myxovirus resistance protein 1, proteasome subunit alpha type-5 and legumain) identified as main classifiers of relapse status were validated by immunohistochemistry (IHC). Two of the proteins are interferon-regulated and on mRNA level known to be repressed by HPV. By both liquid-chromatography tandem mass spectrometry and immunohistochemistry data we could single out a subgroup of HPV negative/relapse-associated tumors. The pathway level data analysis confirmed three of the proteins, and further identified the ubiquitin-proteasome pathway as altered in the high risk subgroup. We show that pathway fingerprinting with resolution on individual tumor level adds biological information that strengthens a generalized protein analysis.

- Articular cartilage is a soft tissue built mainly from collagen and highly negatively charged biological polyelectrolytes. The high negative charge is responsible for crucial properties of cartilage, such as tissue hydration and biomechanical load resistance. As a consequence, breakdown and loss of the polyelectrolytes in cartilage has an adverse effect on its function and there is a need for methods to determine the amount of polyelectrolytes in cartilage. Here we discuss one such method, the delayed gadolinium-enhanced MRI of cartilage (dGEMRIC). dGEMRIC builds on the fact that a negatively charged MRI contrast agent will distribute in an inverse relation to the concentration of polyelectrolytes on account of the electrostatic repulsion between the two. We introduce the method and discuss some of the key assumptions. In particular, we focus on the relaxivity parameter that should be used to convert the measured water spin-lattice relaxation times to a concentration of the contrast agent, the time for reaching equilibrium with respect to penetration of the contrast agent into cartilage and the use of ideal Donnan equilibrium in the further analysis of dGEMRIC data. Finally, we present some examples of clinical applications of the dGEMRIC method.
