Småbiotopsuppföljning i NILS år 2008
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport presenterar resultat för mängden av småbiotoper vid åkermark i det svenska landskapet. Analyserna görs på uppdrag av Jordbruksverket, som underlag för bl.a. utvärderingen av miljökvalitetsmålet Ett rikt odlingslandskap. Särskilda rutiner har tagits fram för att aggregera olika variabler för att välja ut de småbiotoper som uppfyller de krav som Jordbruksverket har ställt upp, ur den befintliga databasen. Urvalet av småbiotoper är anpassat för att överensstämma med det urval av objekt som ingår i det s.k. KULT-stödet (miljöersättning till lantbrukare för skötsel av värdefulla natur- och kulturmiljöer) inom Jordbruksverkets Landsbygdsprogram. Arbetet har utförts vid institutionen för skoglig resurshushållning, Sveriges lantbruks-universitet, Umeå. Resultaten baseras på data från flygbildsinventeringen inom det nationella miljöövervakningsprogrammet NILS (Nationell Inventering av Landskapet i Sverige) vilket följer tillstånd och förändringar i det svenska landskapet och hur dessa påverkar förutsättningarna för den biologiska mångfalden. NILS finansieras av Naturvårdsverket, och ingår där i programområde Landskap. Ett viktigt syfte med programmet är att följa upp de nationella miljökvalitetsmålen för olika naturtyper och fungera som underlag för att se om genomförda policybeslut och miljövårdsåtgärder leder till önskade förbättringar

Rasbiologiskt språkbruk i statens rättsprocess mot sameby : DN Debatt 2015-06-11
- 2015
-
Annan publikation (populärvet., debatt m.m.)abstract
- Statens hantering av forskningsresultat i rättsprocessen med Girjas sameby utgör ett hot mot Sverige som rättsstat och kunskapsnation. Åratal av svensk och internationell forskning underkänns och man använder ett språkbruk som skulle kunna vara hämtat från rasbiologins tid. Nu måste staten ta sitt ansvar och börja agera som en demokratisk rättsstat, skriver 59 forskare.

Tidskriftsartikel (refereegranskat)abstract
- Multiple sclerosis (MS) treatment options have improved significantly over the past decades, but the consequences of MS can still be devastating and the needs for monitoring treatment surveillance are considerable. In the current study we used affinity proteomics technology to identify potential biomarkers which could ultimately be used to as facilitate treatment decisions. We profiled the intra-individual changes in the levels of 59 target proteins using an antibody suspension bead array in serial plasma samples from 44 MS patients during treatment with natalizumab followed by fingolimod. Nine proteins showed decreasing plasma levels during natalizumab treatment, with PEBP1 and RTN3 displaying the most significant changes. Protein levels remained stable during fingolimod treatment for both proteins. The decreasing PEBP1 levels during natalizumab treatment could be validated using ELISA and replicated in an independent cohort. These results support the use of this technology as a high throughput method of identifying potentially useful biomarkers of MS treatment.

- Aims: In general, COVID-19 symptoms are milder in children than inadults, but the experience of the pandemic could increase anxiety andsignificantly affect the life situation of children and adolescents. Itcould also lead to a long-term negative effect on their health. To studyhow the corona pandemic affected the life situation of children andadolescents in Sweden. Methods: A self-reported online survey wasperformed July–November 2020. Cross-sectional data were collectedusing non-probability and convenience sampling methods. The sample consisted of children 6–14 years and their guardians, and adolescents 15–19 years. The questionnaire covered items regarding the life situation including demographics, school situation, social isolation, and an open-ended question to provide a subjective expression of the living situation. A standardized measurement of anxiety was collected using the Children’s Anxiety Questionnaire (CAQ) (scores range 4–12) and the Numeric Rating Scale (NRS)(scores range 0–10). Data were analyzed by descriptive statistics andwith qualitative manifest content analysis. Results: In total, 1487 participants, 768 children with guardians and 719 adolescents participated. Most of the participants, 754 children (97.2%) and 634 adolescents (89.2%) attended school where a mixture of physical attendance and distance learning was reported by 79 children (10.2%)and 261 adolescents (36.7%). Two children (0.3%) and 298 adolescents (41.9%) reported only having distance learning. A larger proportion of children (n = 339, 43.9%) and adolescents (n = 420,59.2%) reported abstaining from leisure activities, while a minority ofchildren (n = 103, 13%) and adolescent (n = 135, 19%) reportedexperiencing a feeling of ‘social isolation’. These experiences ofchanges in daily routine were prominent in the qualitative result. Social restrictions and loss of contact with older relatives led to fear and anxiety. However, for young children, their lives continued torevolve around the everyday things in life rather than the coronapandemic, for the adolescents; however, their life situation was negatively affected by isolation from peer groups and the loss ofschool routine. Conclusion: The experiences by children due toCOVID-19 in Sweden highlight the importance that children continue living their lives as unchanged as possible and that particularly adolescents need receiving greater support with the maintenance of an educational routine.

EVALUATION OF THE HEMOCOMPATIBILITY OF NOVEL POLYMERIC MATERIALS
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- When a biomaterial surface comes in contact with blood an immediate adsorption of plasma proteins to the surface will occur, and the cascade systems in the blood, such as the complement, coagulation and contact system, will be activated to various degrees. The intensity of this reaction will determine the hemocompatibility of the materials. Here we present an evaluation of the link between the composition, the physico-chemical properties and the protein adsorption properties of six newly synthesized polymers (P1-P6) and the hemocompatibility.The hemocompatibility of the polymeric surfaces was evaluated in human blood plasma and whole blood. Commercially available polyvinylchloride (PVC) was used as reference material. The hemocompatibility of the polymeric surfaces was evaluated with regard to complement activation (C3a and sC5-9 generation) and coagulation activation (platelet loss and TAT-formation) and cytokine productions (27 analytes in multiplex assay) after contact with whole blood. Contact activation was quantified by analyses of FXIIa-C1INH, FXIa-C1INH, and kallikrein-C1INH complexes.Polymers P2 (p<0.05 for C3a), P3, P5 and P6 showed less complement activation, and polymers P1 and P4 (p<0.05 for platelet loss), as well as P5 and P6 showed less coagulation activation compared with reference PVC. Polymers P1-P3 induced activation of the contact system, P3 being the most potent. Secretion of 17 cytokines including chemokines and growth factors were differentially influenced by the polymers, P1 and P3 being significantly (p<0.05) more compatible for five of the analytes.Collectively these data demonstrate that the composition of the polymers clearly leads to different biological properties as a consequence of distinctive physico-chemical properties and protein adsorption patterns.1

- Inappropriate complement activation is often responsible for incompatibility reactions that occur when biomaterials are used. Complement activation is therefore a criterion included in legislation regarding biomaterials testing. However, no consensus is yet available regarding appropriate complement-activation-related test parameters. We examined protein adsorption in plasma and complement activation/cytokine release in whole blood incubated with well-characterized polymers. Strong correlations were found between the ratio of C4 to its inhibitor C4BP and generation of 10 (mainly pro-inflammatory) cytokines, including IL-17, IFN-gamma, and IL-6. The levels of complement activation products correlated weakly (C3a) or not at all (C5a, sC5b-9), confirming their poor predictive values. We have demonstrated a direct correlation between downstream biological effects and the proteins initially adhering to an artificial surface after contact with blood. Consequently, we propose the C4/C4BP ratio as a robust, predictor of biocompatibility with superior specificity and sensitivity over the current gold standard. (C) 2014 Elsevier Ltd.

Tidskriftsartikel (refereegranskat)abstract
- Background: Gastric cancer (GC) is clinically heterogenous according to location (cardia/non-cardia) and histopathology (diffuse/intestinal). We aimed to characterize the genetic risk architecture of GC according to its subtypes. Another aim was to examine whether cardia GC and oesophageal adenocarcinoma (OAC) and its precursor lesion Barrett's oesophagus (BO), which are all located at the gastro-oesophageal junction (GOJ), share polygenic risk architecture.Methods: We did a meta-analysis of ten European genome-wide association studies (GWAS) of GC and its subtypes. All patients had a histopathologically confirmed diagnosis of gastric adenocarcinoma. For the identification of risk genes among GWAS loci we did a transcriptome-wide association study (TWAS) and expression quantitative trait locus (eQTL) study from gastric corpus and antrum mucosa. To test whether cardia GC and OAC/BO share genetic aetiology we also used a European GWAS sample with OAC/BO.Findings: Our GWAS consisting of 5816 patients and 10,999 controls highlights the genetic heterogeneity of GC according to its subtypes. We newly identified two and replicated five GC risk loci, all of them with subtype-specific association. The gastric transcriptome data consisting of 361 corpus and 342 antrum mucosa samples revealed that an upregulated expression of MUC1, ANKRD50, PTGER4, and PSCA are plausible GC-pathomechanisms at four GWAS loci. At another risk locus, we found that the blood-group 0 exerts protective effects for non-cardia and diffuse GC, while blood-group A increases risk for both GC subtypes. Furthermore, our GWAS on cardia GC and OAC/BO (10,279 patients, 16,527 controls) showed that both cancer entities share genetic aetiology at the polygenic level and identified two new risk loci on the single-marker level.Interpretation: Our findings show that the pathophysiology of GC is genetically heterogenous according to location and histopathology. Moreover, our findings point to common molecular mechanisms underlying cardia GC and OAC/BO.
