Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- I detta kapitel fokuserar vi hur universitetens samverkan med det omgivande samhället kan bidra med ny forskning och samtidigt verka för spridning av nya forskningsresultat. I forskarskolan Communicate science in school (CSiS) deltar tio lärare i en forskarutbildning där deltagarna efter avslutad utbildning erhåller en licentiatexamen i naturvetenskapernas didaktik. Ett viktigt syfte med forskarskolan är att fortlöpande samla förvaltningschefer, rektorer och forskarstuderande för att diskutera och förstärka skolutveckling i förskolan, grundskolan och gymnasieskolan på vetenskaplig grund. Det innebär att initiera samtal om hur de berörda lärarnas kunskaper ska komma kommunernas skolutveckling till godo efter avlagd examen. Gemensamt för samtliga forskarstuderande har varit att problematisera skolämnenas innehåll i relation till modern forskning i naturvetenskap och teknik men också att ta del av internationell utbildningsvetenskaplig forskning i relation till undervisningsformer och organisering av själva undervisningen.

Synthesis of theoretical and empirical experineces from nutrient and cyprinid reductions in Lake Ringsjön
- 1999
-
Ingår i: Hydrobiologia. - 0018-8158. ; 404, s. 145-156
-
Tidskriftsartikel (refereegranskat)abstract
- The reduction in external phosphorus load to Lake Ringsjön during the 1980s, did not result in improved water transparency during the following ten-year period. Furthermore, a fish-kill in the Eastern Basin of the lake, in addition to a cyprinid reduction programme (biomanipulation; 1988–1992), in contrast to theory, did not lead to any increase in zooplankton biomass or size. This absence of response in the pelagic food chain may have been attributed to the increase in abundance of YOY (0+) fish, following the fish reduction programme. Despite the lack of effect on zooplankton, there was a decrease in phytoplankton biomass, a change in species composition and an increase in water transparency following biomanipulation. In 1989, one year after the fish-kill in Eastern Basin, the Secchi depth (summer mean) increased from 60 cm to 110 cm. In the following years, water transparency increased further, despite an increase in phosphorus loading. An unexpected effect of the biomanipulation was an increase in benthic invertebrate and staging waterfowl abundances, which occurred 2–4 years after fish reduction. Hence, the response in the benthic community following biomanipulation was considerably stronger than in the pelagic community. A likely explanation is that reduction in abundance of the benthic feeding fish species bream (Abramis brama), strongly affected the benthic invertebrate fauna. In this paper, we present what we believe happened in Lake Ringsjön, and which processes are likely to have been important at various stages of the restoration process.

Positive and Negative Aspects of Colostomy Irrigation A Patient and WOC Nurse Perspective
- 2010
-
Ingår i: JOURNAL OF WOUND OSTOMY AND CONTINENCE NURSING. - : Lippincott Williams & Wilkins. - 1071-5754 .- 1528-3976. ; 37:5, s. 511-516

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: Colostomy irrigation (CI) is an effective method to achieve fecal continence in selected persons with a colostomy. The primary aims of the study were to find out to what extent the WOC nurses used CI in their practice and what kind of information the WOC nurses gave patients if they provided explanations and potential solutions when irrigation was not successful in preserving continence. A further aim was to find out, from a patients' perspective, the positive and negative aspects of practicing CI and how they perform CI. METHODS: The study employed a mixed quantitative and qualitative approach. Data from WOC nurses were obtained by means of a structured questionnaire and by means of structured telephone interviews with patients who performed CI. SUBJECTS AND SETTING: Questionnaires were sent out to 89 WOC nurses in Sweden, and 61 (69%) questionnaires were returned. Thirty-nine patients, median age 67 years, from 5 hospitals participated in the interview study. RESULTS: Sixty-four percent of the WOC nurse respondent always informed patients about CI. Forty-four percent of patients did not remember all the information they had been given by the WOC nurse regarding CI before starting with the procedure. Eighty-seven percent reported changing routines from how they initially performed CI over the years. Almost all (97%) of the respondents described positive aspects of CI. The 2 primary positive aspects described by participants were (1) feeling secure and (2) having an empty pouch. CONCLUSION: Persons living with a colostomy who regularly performed CI reported positive benefits associated with the procedure including a feeling of security and having an empty pouch. Despite these potential benefits, not all patients with a colostomy who are appropriate candidates for CI are offered information about the method from the WOC nurses.

Tidskriftsartikel (refereegranskat)abstract
- A new series of dual low nanomolar benzothiazole inhibitors of bacterial DNA gyrase and topoisomerase IV were developed. The resulting compounds show excellent broad-spectrum antibacterial activities against Gram-positive Enterococcus faecalis, Enterococcus faecium and multidrug resistant (MDR) Staphylococcus aureus strains [best compound minimal inhibitory concentrations (MICs): range, <0.03125–0.25 μg/mL] and against the Gram-negatives Acinetobacter baumannii and Klebsiella pneumoniae (best compound MICs: range, 1–4 μg/mL). Lead compound 7a was identified with favorable solubility and plasma protein binding, good metabolic stability, selectivity for bacterial topoisomerases, and no toxicity issues. The crystal structure of 7a in complex with Pseudomonas aeruginosa GyrB24 revealed its binding mode at the ATP-binding site. Expanded profiling of 7a and 7h showed potent antibacterial activity against over 100 MDR and non-MDR strains of A. baumannii and several other Gram-positive and Gram-negative strains. Ultimately, in vivo efficacy of 7a in a mouse model of vancomycin-intermediate S. aureus thigh infection was also demonstrated.

Lysophophatidylcholine 16:0 mediates chronic joint pain associated to rheumatic diseases through acid-sensing ion channel 3
- 2022
-
Ingår i: Pain. - : International Association for the Study of Pain. - 0304-3959 .- 1872-6623. ; 163:10, s. 1999-2013

Tidskriftsartikel (refereegranskat)abstract
- Rheumatic diseases are often associated to debilitating chronic pain, which remains difficult to treat and requires new therapeutic strategies. We had previously identified lysophosphatidylcholine (LPC) in the synovial fluids from few patients and shown its effect as a positive modulator of acid-sensing ion channel 3 (ASIC3) able to induce acute cutaneous pain in rodents. However, the possible involvement of LPC in chronic joint pain remained completely unknown. Here, we show, from 2 independent cohorts of patients with painful rheumatic diseases, that the synovial fluid levels of LPC are significantly elevated, especially the LPC16:0 species, compared with postmortem control subjects. Moreover, LPC16:0 levels correlated with pain outcomes in a cohort of osteoarthritis patients. However, LPC16:0 do not appear to be the hallmark of a particular joint disease because similar levels are found in the synovial fluids of a second cohort of patients with various rheumatic diseases. The mechanism of action was next explored by developing a pathology-derived rodent model. Intra-articular injections of LPC16:0 is a triggering factor of chronic joint pain in both male and female mice, ultimately leading to persistent pain and anxiety-like behaviors. All these effects are dependent on ASIC3 channels, which drive sufficient peripheral inputs to generate spinal sensitization processes. This study brings evidences from mouse and human supporting a role for LPC16:0 via ASIC3 channels in chronic pain arising from joints, with potential implications for pain management in osteoarthritis and possibly across other rheumatic diseases.

Expanding the Clinical Spectrum of Phenotypes Caused by Pathogenic Variants in PLOD2
- 2018
-
Ingår i: Journal of Bone and Mineral Research. - : Wiley. - 0884-0431. ; 33:4, s. 753-760
-
Tidskriftsartikel (refereegranskat)abstract
- Osteogenesis imperfecta (OI) is a strikingly heterogeneous group of disorders with a broad range of phenotypic variations. It is also one of the differential diagnoses in bent bone dysplasias along with campomelic dysplasia and thanatophoric dysplasia and can usually be distinguished by decreased bone mineralization and bone fractures. Bent bone dysplasias also include syndromes such as kyphomelic dysplasia (MIM:211350) and mesomelic dysplasia Kozlowski-Reardon (MIM249710), both of which have been under debate regarding whether or not they are a real entity or simply a phenotypic manifestation of another dysplasia including OI. Bruck syndrome type 2 (BRKS2; MIM:609220) is a rare form of autosomal recessive OI caused by biallelic PLOD2 variants and is associated with congenital joint contractures with pterygia. In this report, we present six patients from four families with novel PLOD2 variants. All cases had multiple fractures. Other features ranged from prenatal lethal severe angulation of the long bones as in kyphomelic dysplasia and mesomelic dysplasia Kozlowski-Reardon through classical Bruck syndrome to moderate OI with normal joints. Two siblings with a kyphomelic dysplasia-like phenotype who were stillborn had compound heterozygous variants in PLOD2 (p.Asp585Val and p.Ser166*). One infant who succumbed at age 4 months had a bent bone phenotype phenotypically like skeletal dysplasia Kozlowski-Reardon (with mesomelic shortening, camptodactyly, retrognathia, cleft palate, skin dimples, but also with fractures). He was homozygous for the nonsense variant (p.Trp561*). Two siblings had various degrees of Bruck syndrome caused by the homozygous missense variant, p.His687Arg. Furthermore a boy with a clinical presentation of moderate OI had a possibly pathogenic homozygous variant p.Trp588Cys. Our experience of six patients with biallelic pathogenic variants in PLOD2 expands the phenotypic spectrum in the PLOD2-related phenotypes.

Gender, alexithymia and physical inactivity associated with abdominal obesity in type1 diabetes mellitus : a cross sectional study at a secondary care hospital diabetes clinic
- 2017
-
Ingår i: BMC Obesity. - : Springer. - 2052-9538. ; 4
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Obesity is linked to cardiovascular diseases and increasingly common in type 1 diabetes mellitus (T1DM) since the introduction of intensified insulin therapy. Our main aim was to explore associations between obesity and depression, anxiety, alexithymia and self-image measures and to control for lifestyle variables in a sample of persons with T1DM. Secondary aims were to explore associations between abdominal and general obesity and cardiovascular complications in T1DM.Methods: Cross sectional study of 284 persons with T1DM (age 18–59 years, men 56%), consecutively recruited from one secondary care hospital diabetes clinic in Sweden. Assessments were performed with self-report instruments (Hospital Anxiety and Depression Scale, Toronto Alexithymia Scale-20 items and Structural Analysis of Social Behavior). Anthropometrics and blood samples were collected for this study and supplemented with data from the patients ’ medical records. Abdominal obesity was defined as waist circumference men/women (meters): ≥ 1.02/≥0.88, and general obesity as BMI ≥30 kg/m2 for both genders. Abdominal obesity was chosen in the analyses due to the high association with cardiovascular complications. Different explanatory logistic regression models were elaborated for the associations and calibrated and validated for goodness of fit with the data variables.Results: The prevalence of abdominal obesity was 49/284 (17%), men/women: 8%/29% (P < 0.001). Abdominal obesity was associated with women (AOR 4.9), physical inactivity (AOR 3.1), alexithymia (AOR 2.6) and age (per year) (AOR 1.04). One of the three alexithymia sub factors, “difficulty identifying feelings” (AOR 3.1), was associated with abdominal obesity. Gender analyses showed that abdominal obesity in men was associated with “difficulty identifying feelings ” (AOR 7.7), and in women with use of antidepressants (AOR 4.3) and physical inactivity (AOR 3.6). Cardiovascular complications were associated with abdominal obesity (AOR 5.2).Conclusions: Alexithymia, particularly the alexithymia subfactor “difficulty identifying feelings”, physical inactivity, and women, as well as cardiovascular complications were associated with abdominal obesity. As abdominal obesity is detrimental in diabetes due to its association with cardiovascular complications, our results suggest two risk factor treatment targets: increased emotional awareness and increased physical activity.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this study is to highlight problems regarding the status of children in determining the granting of residence permits. Central to the study are the rules contained in the Swedish Aliens Act (2005:716) about hearing children in the course of proceedings and the child’s best interests. The rules are based on Articles 3 and 12 respectively, in the United Nations Convention on the Rights of the Child (CRC). They were introduced into the Swedish legislation in 1997, after an intense debate questioning whether Sweden was meeting its obligations under the Convention. The application in aliens matters has, however, continued to be criticized after the revision of 1997, especially in matters concerning children. In 2006 a new Aliens Act came into force, involving a shift in the handling of such matters from administrative authorities and the Government to a system where appeals are tried in administrative courts. The legislation also involves comprehensive changes concerning the material legislation. The question has been raised, however, as to whether these changes have had any vital impact concerning the general construction of the material regulation. The apparent gap between the legislator’s intentions and the application of the law raises questions about the limitations of law and how the spirit and intentions of the CRC have been implemented in the Aliens Act, and, in view of this, the limits of law. The study involves an analysis of the fundamental premises that the legislation and application rest on, the general provisions of the proceedings and the technical formulation and also the material content of these rules. There is also an analysis of the impact and function of the legislation in practical applications. The conclusion is that the legislation allows extensive scope for assessing the circumstances in each case. This is the case, particularly in matters concerning children. Nevertheless, in practical applications, children often become irrelevant; children are simply not the real focus of the laws that affect them. Key words: Children’s rights, residence permit, asylum, immigration, equality, feminist perspectives. Eva Nilsson, Juridiska institutionen, Umeå universitet, 901 87 Umeå.

Elevated inflammatory proteins in cerebrospinal fluid from patients with painful knee osteoarthritis are associated with reduced symptom severity
- 2020
-
Ingår i: Journal of Neuroimmunology. - : ELSEVIER. - 0165-5728 .- 1872-8421. ; 349
-
Tidskriftsartikel (refereegranskat)abstract
- Neuroinflammation and periphery-to-CNS neuroimmune cross-talk in patients with painful knee osteoarthritis (OA) are poorly understood. We utilized proximity extension assay to measure the level of 91 inflammatory proteins in CSF and serum from OA patients and controls. The patients had elevated levels of 48 proteins in CSF indicating neuroinflammation. Ten proteins were correlated between CSF and serum and potentially involved in periphery-to-CNS neuroimmune cross-talk. Seven CSF proteins, all with previously reported neuroprotective effects, were associated with lower pain intensity and milder knee-related symptoms. Our findings indicate that neuroinflammation in OA could be protective and associated with less severe symptoms.

Health-Related Quality-of-Life (HRQoL) on an Average of 12 Years After Gastric Bypass Surgery
- 2015

Tidskriftsartikel (refereegranskat)abstract
- It is evident that morbidly obese patients have a low health-related quality-of-life (HRQoL), and this low HRQoL has become a common reason for them to seek bariatric surgery. Several HRQoL studies demonstrate a dramatic postoperative improvement, but most of these have had a short follow-up period.An observational, cross-sectional study for HRQoL was conducted to study 486 patients (average age of 50.7 +/- 10.0 years, with 84 % of them being female) operated with gastric bypass (GBP) in the period 1993 to 2003 at the University Hospitals of A-rebro and Uppsala. Mean follow-up after gastric bypass was 11.5 +/- 2.7 years (range 7-17). Two HRQoL instruments were used, SF-36 and the Obesity-related Problems scale (OP). The study group was compared with two control groups, both matched for age and gender, one from the general population and one containing morbidly obese patients evaluated and awaiting bariatric surgery.The study group scored better in the SF-36 domains (all four physical domains and the vitality subscore) and OP scale compared to obese controls, but their HRQoL scores were lower than those of the general population. HRQoL was better among younger patients and in the following subgroups: men, patients with satisfactory weight loss, satisfied with the procedure, free from co-morbidities and gastrointestinal symptoms, employment, good oral status and those not hospitalised or regularly followed up for non-bariatric reasons.Long-term follow-up after GBP for morbid obesity showed better scores in most aspects of HRQoL compared to obese controls but did not achieve the levels of the general population. Patients with better medical outcome after gastric bypass operation had better HRQoL.

Unraveling the neuroimmune interface in chronic pain-the association between cytokines in the cerebrospinal fluid and pain in patients with lumbar disk herniation or degenerative disk disease
- 2024

Tidskriftsartikel (refereegranskat)abstract
- Supplemental Digital Content is Available in the Text.A cross-sectional study finding elevated cerebrospinal fluid protein levels in patients with degenerative disk disease and lumbar disk herniation, suggesting neuroimmune activity. The interaction between neuroimmunity and pain was complex. Recent evidence highlights the importance of the neuroimmune interface, including periphery-to-central nervous system (CNS) neuroimmune crosstalk, in chronic pain. Although neuroinflammatory processes have been implicated in central sensitization for a long time, their potential neuroprotective and analgesic effects remain relatively elusive. We have explored the relationships between cytokine expression and symptom severity, and candidates for periphery-to-CNS crosstalk. Patients with degenerative disk disease (DDD) (nociceptive pain) or patients with lumbar disk herniation (LDH) with radiculopathy (predominantly neuropathic pain) completed questionnaires regarding pain and functional disability, underwent quantitative sensory testing, and provided blood and cerebrospinal fluid (CSF) samples. Proximity extension assay (PEA) was used to measure the levels of 92 inflammatory proteins in the CSF and serum from a total of 160 patients and controls, and CSF/serum albumin quotients was calculated for patients with DDD and patients with LDH. We found signs of neuroimmune activation, in the absence of systemic inflammation. Regarding periphery-to-CNS neuroimmune crosstalk, there were significant associations between several cytokines and albumin quotient, despite the latter being primarily at subclinical levels. The cytokines CCL11, CD5, IL8, and MMP-10 were elevated in the CSF, had positive correlations between CSF and serum levels, and associated in a nonlinear manner with back, but not leg, pain intensity in the LDH, but not the DDD, group. In conclusion, we found evidence for neuroimmune activation in the CNS of both patient groups in the absence of systemic inflammation and signs of a communication between CSF and serum. Complex and disease-specific associations were found between cytokines in CSF and back pain intensity.

- I artikeln belyses den samlade svenska diskrimineringslagen (2009) från ett perspektiv av intersektionalitet. Genom en analys av ett antal mål från den svenska arbetsdomstolen där minst två diskrimineringsgrunder har varit aktuella, visar författare att det det både brister hos arbetsdomstolen när det gäller att förstå individers utsatthet när det gäller multipel diskriminering och lagen som sådan, eftersom den saknar instrument för att bedöma och hantera liknande tvister. Författaren avslutar artikeln med att förorda ett nytt perspektiv på rättvisa: kompensatorisk (kommutativ) global rättvisa.

Exosome uptake depends on ERK1/2-heat shock protein 27 signalling and lipid raft-mediated endocytosis negatively regulated by caveolin-1.

Ingår i: Journal of Biological Chemistry. - 1083-351X. ; 288:24, s. 17713-17724

Tidskriftsartikel (refereegranskat)abstract
- The role of exosomes in cancer can be inferred from the observation that they transfer tumor cell derived genetic material and signalling proteins, resulting in e.g. increased tumor angiogenesis and metastasis. However, the membrane transport mechanisms and the signalling events involved in the uptake of these virus-like particles remain ill-defined. We now report that internalization of exosomes derived from glioblastoma (GBM) cells involves nonclassical, lipid raft-dependent endocytosis. Importantly, we show that the lipid raft associated protein caveolin-1 (CAV1), in analogy with its previously described role in virus uptake, negatively regulates the uptake of exosomes. We find that exosomes induce the phosphorylation of several downstream targets known to associate with lipid rafts as signalling and sorting platforms, such as extracellular signal-regulated kinase-1/2 (ERK1/2) and heat shock protein 27 (HSP27). Interestingly, exosome uptake appears dependent on unperturbed ERK1/2-HSP27 signalling, and ERK1/2 phosphorylation is under negative influence by CAV1 during internalization of exosomes. These findings significantly advance our general understanding of exosome-mediated uptake and offer potential strategies for how this pathway may be targeted through modulation of CAV1 expression and ERK1/2 signaling.

- (1) Background: Overweight and obesity in children have increased worldwide and tend to persist into adolescence and adulthood. The Child Health Service (CHS) has an important role in providing health-promotive interventions, and such interventions are required to be documented in a child’s health record. The aim of the study was to investigate Child Health Care (CHC) nurses’ documentation of weight-related, health-promotive interventions in the Child Health Care Record (CHCR) regarding lifestyle habits in connection to the four-year visit. (2) Methods: A record review of 485 CHCRs using a review template was accomplished. Of the included CHS units, four used electronic records and two used paper records. Chi-square tests and Spearman’s rank-order correlations were used to analyse data. (3) Results: The results showed that CHC nurses document interventions regarding lifestyle habits to a low extent, although children with overweight/obesity seemed to undergo more interventions. There was also a difference between electronic and paper records. (4) Conclusions: The consequences of not documenting the interventions in the CHCR make it difficult to follow up and demonstrate the quality of the CHC nurse’s work. There is a need for more research to gain a deeper understanding of the reasons that the work of CHC nurses is not visible in children’s health records.

There is a need for more research to gain a deeper understanding of the reasons that the work of CHC nurses is not visible in children’s health records.

Tidskriftsartikel (refereegranskat)abstract
- Aim: To determine if patients with untreated chronic lymphocytic leukemia (CLL) benefit from vaccination with a 13-valent conjugated pneumococcal vaccine (PCV13), Prevenar13®, compared with a 23-valent capsular polysaccharide vaccine (PPSV23), Pneumovax®, in terms of immune response. Background: Patients with CLL have an increased risk for infection and Streptococcus pneumoniae is one of the most common pathogens with high morbidity. Patients with CLL are known to respond poorly to the traditionally used polysaccharide vaccines. Conjugation of polysaccharide to protein carriers renders a thymus-dependent, memory-inducing and more immunogenic vaccine. In patients with CLL, there is no consensus on a recommendation for pneumococcal vaccination, due to a lack of comparative studies. Methods: 128 treatment naïve CLL patients from eight hematology clinics in Sweden were randomized to vaccination with PCV13 (n=63) or PPSV23 (n=65) after stratification by IgG levels and CLL clinical stage (Rai). Blood samples for evaluation of immune response were obtained at baseline, at one and at six months after vaccination. Analyses for each of the 12 pneumococcal serotypes common for PCV13 and PPSV23 were performed by opsonophagocytic assay (OPA) and enzyme-linked immunosorbent assay (ELISA). Results: PCV13 elicited a superior immune response than PPSV23 in 10/12 serotypes one month after vaccination and in 5/12 serotypes six months after vaccination, measured as OPA geometric mean titers (GMTs). Geometric mean concentrations of serotype-specific IgG antibodies elicited by PCV13 as measured by ELISA, were higher than those elicited by PPSV23 in half of the common serotypes, both after one and six months. The proportion of patients with good response (defined as response in 8 of 12 common serotypes according to predefined response criteria) was higher in PCV13 recipients than in PPSV23 recipients after one month (40% vs. 22%, p=0.034) as well as after six months (33% vs. 17%, p=0.041). Never did PPSV23 trigger a better immune response for any of the serotypes, than PCV13, regardless of analysis. For two of the serotypes, OPA GMTs were lower at the six months than at the one-month follow up. Negative predictive factors for vaccination response were hypogammaglobulinemia and long disease duration. Both vaccines were well tolerated. Conclusions: In patients with previously untreated CLL, the efficacy of PCV13 in terms of immune response is superior to PPSV23 for many serotypes common for the two vaccines. PCV13 should be considered as a part in vaccination programs against Streptococcus pneumoniae for these patients and administered as early as possible during the course of the disease.

Stärk prostituerade personers möjlighet att kräva skadestånd [Strenghten Prostituted Persons’ Possibilities to Demand Damages].

Annan publikation (populärvet., debatt m.m.)abstract
- GÖTEBORGS-POSTEN 10 Maj, 2011, Debatt I sexköpsmål betalar köparen i dag främst böter till staten och prostituerade personer kallas endast som vittnen. Möjligheten för prostituerade människor att yrka skadestånd finns, men har aldrig använts sen lagen kom till. Vi vill se en utredning som ser över hur deras förutsättningar för skadestånd kan förbättras, skriver bland andra Carina Hägg (S). Justitieutskottet publicerade nyligen sitt betänkande som föreslår ett skärpt straff för sexköp till riksdagen. Samtidigt skriver majoriteten att en målsägandeställning ”är inte i sig nödvändig för att kunna föra talan om skadestånd eller ens för att få denna talan handlagd,” men åklagaren är inte skyldig att föra talan för andra än målsäganden. Detta förtydligande av rättsläget vad gäller skadestånd är välkommet, men det tycks vara lika tydligt att personen som köps i prostitution är den mot vilken brottet sexköp är begånget. Om denna möjlighet att få skadestånd redan existerar reser det emellertid frågetecken varför ingen prostituerad person ännu har fått sådant skadestånd för att ha blivit köpt för sex. Inte en 14-årig psykiskt utvecklingsstörd flicka (HovR över Skåne & Blekinge mål B 2917-10 & B 3184-10), eller en vuxen som öppet tillstods vara maktlös av en Hovrätt vilken uttalade att sexköparna ”insett och utnyttjat” faktumet, vanligt i prostitution, att den prostituerade personen ”befunnit sig i ett sådant underläge mot de två männen att det måste ha framstått som i det närmaste omöjligt för henne att vägra den andre samlag eller i övrigt påverka situationen” (RH 2008:59). När nu de styrande således har förtydligat sexköpslagen i detta avseende kommer förhoppningsvis polis, åklagare, målsägandebiträden, domstolar, socialarbetare och andra aktörer hädanefter upplysa alla prostituerade personer om deras rättigheter till skadestånd. Icke desto mindre så verkar ytterligare utredning av skadestånd för sexköp vara på sin plats, vilket minoritetsmotionerna har föreslagit utöver deras stöd för regeringens proposition. Mycket är redan känt. En del köpare anser att betalning ger dem rätt att göra vad helst de vill med kvinnan de köper. Många misshandlas svårt av köpare. Bland 200 prostituerade kvinnor i San Francisco våldtogs 70% eller misshandlades på liknande sätt av köpare i genomsnitt 31 gånger. Bland 55 före detta prostituerade kvinnor i Portland, Oregon, blev 78% våldtagna 49 gånger per år (33 gånger av en torsk) och 84% utsattes för grov misshandel i genomsnitt 103 gånger per år (45 gånger av en torsk). Tjugoen procent bland 222 kvinnor som prostituerades i Chicago vilka studerades medgav uttryckligen att de hade våldtagits över 10 gånger i eskortprostitution, gatuprostitution, och när de prostituerats privat i sina hem. De flesta av förövarna var torskar. Två Kanadensiska federala utredningar fann att torskarna utövar mest sexuellt våld mot prostituerade personer (1984, s. 1026; 1985, s. 388). En prostituerad kvinna betrodd av Svea Hovrätt (mål B 4789-09, s. 6) när hon uppgav hur en hallick bestraffade henne genom att skicka henne till (med Södertörns Tingsrätts neutraliserande ord) ”hårdhänta”, ”arga” och de mest ”elaka” torskarna (mål B 13571-07, s. 12) fick likväl inga skadestånd från dessa köpare. Sammanhanget med skador på prostituerade människor i prostitution är obestridlig, vars gottgörelse skulle kunna både ge dem upprättelse och möjliggöra för dem att fatta verkliga val vad gäller deras liv. Maktobalansen i prostitution och följderna av hanteringen av prostituerade personer i sexindustrin visar sig i information om misshandel och ohälsa liksom, hos 68% av 827 respondenter i nio länder, posttraumatiska stressymptom (PTSD) jämförbara med den hos tortyroffer, veteraner från krigszoner, och våldtagna kvinnor. En nyare studie med 46 personer som bland annat prostituerats på bordeller och eskortfirmor i Sydkorea och en kontrollgrupp visade att PTSD var signifikant även när man kontrollerat för olika former av misshandel under barndomen. Resultatet stärker slutsatsen att prostitution i sig själv utsätter majoriteten prostituerade personer för lidande. Åttionio procent av människor i prostitution i nio länder som ställdes frågan ”vad behöver du mest” svarade att ta sig ur prostitution. Men de känner inte att de kan. Skadestånd och stöd skulle kunna göra detta möjligt. Kommer utskottsmajoritetens uppmaning till rättsväsendet att tillämpa gällande rätt och bedöma skadestånd att räcka till? Givet att dessa juridiska och sociala förhållanden har existerat, och med kännedom så existerat över det gångna decenniet efter att sexköpslagen antogs utan skadestånd eller stöd till en enda prostituerad person, så förtjänar frågan minst sagt ytterligare utredning. Minoriteten (s & v) uppmanar således, som ett tillägg till majoritetens förslag, att en departements- eller expertutredning rimligen tillsätts för att ytterligare utreda och återkomma till riksdagen med ett förslag som kommer skapa bättre förutsättningar än som existerar i dag för den prostituerade personen att få skadestånd.

Going to extremes - a metagenomic journey into the dark matter of life
- 2021
-
Ingår i: FEMS Microbiology Letters. - : Oxford University Press (OUP). - 1574-6968. ; 368:12

Forskningsöversikt (refereegranskat)abstract
- The Virus-X-Viral Metagenomics for Innovation Value-project was a scientific expedition to explore and exploit uncharted territory of genetic diversity in extreme natural environments such as geothermal hot springs and deep-sea ocean ecosystems. Specifically, the project was set to analyse and exploit viral metagenomes with the ultimate goal of developing new gene products with high innovation value for applications in biotechnology, pharmaceutical, medical, and the life science sectors. Viral gene pool analysis is also essential to obtain fundamental insight into ecosystem dynamics and to investigate how viruses influence the evolution of microbes and multicellular organisms. The Virus-X Consortium, established in 2016, included experts from eight European countries. The unique approach based on high throughput bioinformatics technologies combined with structural and functional studies resulted in the development of a biodiscovery pipeline of significant capacity and scale. The activities within the Virus-X consortium cover the entire range from bioprospecting and methods development in bioinformatics to protein production and characterisation, with the final goal of translating our results into new products for the bioeconomy. The significant impact the consortium made in all of these areas was possible due to the successful cooperation between expert teams that worked together to solve a complex scientific problem using state-of-the-art technologies as well as developing novel tools to explore the virosphere, widely considered as the last great frontier of life.

Crystal structure of DNA polymerase I from Thermus phage G20c
- 2022
-
Ingår i: Acta crystallographica. Section D, Structural biology. - 2059-7983. ; 78:Pt 11, s. 1384-1398

Tidskriftsartikel (refereegranskat)abstract
- This study describes the structure of DNA polymerase I from Thermus phage G20c, termed PolI_G20c. This is the first structure of a DNA polymerase originating from a group of related thermophilic bacteriophages infecting Thermus thermophilus, including phages G20c, TSP4, P74-26, P23-45 and phiFA and the novel phage Tth15-6. Sequence and structural analysis of PolI_G20c revealed a 3'-5' exonuclease domain and a DNA polymerase domain, and activity screening confirmed that both domains were functional. No functional 5'-3' exonuclease domain was present. Structural analysis also revealed a novel specific structure motif, here termed SβαR, that was not previously identified in any polymerase belonging to the DNA polymerases I (or the DNA polymerase A family). The SβαR motif did not show any homology to the sequences or structures of known DNA polymerases. The exception was the sequence conservation of the residues in this motif in putative DNA polymerases encoded in the genomes of a group of thermophilic phages related to Thermus phage G20c. The structure of PolI_G20c was determined with the aid of another structure that was determined in parallel and was used as a model for molecular replacement. This other structure was of a 3'-5' exonuclease termed ExnV1. The cloned and expressed gene encoding ExnV1 was isolated from a thermophilic virus metagenome that was collected from several hot springs in Iceland. The structure of ExnV1, which contains the novel SβαR motif, was first determined to 2.19 Å resolution. With these data at hand, the structure of PolI_G20c was determined to 2.97 Å resolution. The structures of PolI_G20c and ExnV1 are most similar to those of the Klenow fragment of DNA polymerase I (PDB entry 2kzz) from Escherichia coli, DNA polymerase I from Geobacillus stearothermophilus (PDB entry 1knc) and Taq polymerase (PDB entry 1bgx) from Thermus aquaticus.

Activation of NF-kappa B in Synovium versus Cartilage from Patients with Advanced Knee Osteoarthritis : A Potential Contributor to Inflammatory Aspects of Disease Progression
- 2018
-
Ingår i: Journal of Immunology. - : AMER ASSOC IMMUNOLOGISTS. - 0022-1767 .- 1550-6606. ; 201:7, s. 1918-1927

Tidskriftsartikel (refereegranskat)abstract
- The aim was to assess the activation and association of the NF-kappa B system across synovial membrane (SM) and articular cartilage (AC) in patients with knee osteoarthritis (OA) and ascertain its potential effects on catabolic mediator expression in advanced OA. SM and AC were obtained from 40 OA patients undergoing total knee arthroplasty and from 19 postmortem control subjects. NF-kappa B subunit RelA in nuclear and cytosolic fractions and NF-kappa B1-DNA binding in nuclear extracts was assessed by ELISA, whereas NFKB1, RELA, IL-8, IL-6, and MMP3 gene expression were analyzed by reverse transcriptase-quantitative PCR in tissues. We observed higher SM nuclear RelA protein levels and upregulated NF-kappa B1-DNA binding in OA patients compared with postmortem controls. However, in AC, lower nuclear RelA levels were observed compared with cytosolic extracts in patients. Nuclear RelA levels correlated positively with NF-kappa B1-DNA binding in SM and AC in patients. SM RELA and MMP3 mRNA levels were upregulated, whereas IL-8 and IL-6 as well as AC RELA were downregulated in patients compared with controls. In SM, nuclear RelA levels correlated positively with MMP3 gene expression in patients. A negative correlation was observed between SM nuclear RelA levels and AC NF-kappa B1-DNA binding, and SM nuclear NF-kappa B1-DNA binding correlated negatively with AC MMP3 and NFKB1 mRNA levels in patients. These findings highlight NF-kappa B-triggered cross-talk and feedback mechanisms between SM and AC in OA. Further, our findings strongly support a role for an activated NF-kappa B system in the transcriptional mechanism of inflammatory processes, especially in SM of patients with advanced OA.

NF-κB-Associated Pain-Related Neuropeptide Expression in Patients with Degenerative Disc Disease.
- 2019

Ingår i: International Journal of Molecular Sciences. - : MDPI AG. - 1661-6596 .- 1422-0067. ; 20:3

Tidskriftsartikel (refereegranskat)abstract
- The role of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) has been highlighted in mechanisms underlying inflammatory and neuropathic pain processes. The present study was designed to investigate whether NF-κB signaling is associated with pain-related neuropeptide expression in patients with chronic back pain related to degenerative disc disease (DDD). Intervertebral disc (IVD) tissues were collected from forty DDD patients undergoing disc replacement or fusion surgery, and from eighteen postmortem (PM) control subjects. RELA, NFKB1, CGRP, TAC1, TRPV1, and MMP-3 gene expression were analyzed by RT-qPCR, while NF-κB subunit RelA and NF-κB1⁻DNA binding in nuclear extracts and calcitonin gene related peptide (CGRP), substance P (SP), and transient receptor potential, subfamily V, member 1 (TRPV1) protein levels in cytosolic extracts of tissues were assessed by enzyme-linked immunosorbent assay (ELISA). An upregulated NF-κB1⁻DNA binding, and higher CGRP and TRPV1 protein levels were observed in DDD patients compared to PM controls. In DDD patients, NF-κB1⁻DNA binding was positively correlated with nuclear RelA levels. Moreover, NF-κB1⁻DNA binding was positively associated with TRPV1 and MMP-3 gene and SP and TRPV1 protein expression in DDD patients. Our results indicate that the expression of SP and TRPV1 in IVD tissues was associated with NF-κB activation. Moreover, NF-κB may be involved in the generation or maintenance of peripheral pain mechanisms by the regulation of pain-related neuropeptide expression in DDD patients.

Increased noise levels cause behavioural and distributional changes in Atlantic cod and saithe in a large public aquarium—A case study
- 2023

Ingår i: Aquaculture, Fish and Fisheries. - : John Wiley & Sons. - 2693-8847.

Tidskriftsartikel (refereegranskat)abstract
- Abstract Investigating the effects of underwater noise on aquatic animals is a research field that is receiving rapidly increasing attention. Despite this, surprisingly few studies have addressed the potential impacts of noise in a marine animal husbandry setting. In this regard, the behaviour of fish in public aquariums can be used as an indicator of well-being, and noise is known to cause behavioural changes. This case study investigates the behaviour of cod (Gadus morhua) and saithe (Pollachius virens) in a large public aquarium when exposed to increased noise levels originating from an aquarium renovation carried out by construction divers. Swimming behaviour, group formation and vertical distribution, along with yawning and scratching frequencies of the fish, were analysed from video recordings made before, during and after the exposure to increased noise levels. The same parameters were also analysed to evaluate potential effects of the presence of divers when not making renovation noise, compared to fish behaviour prior to the renovation. There was a slight change in the depth distribution of both species and a decrease in the number of scratches in cod due to the presence of divers that were not making renovation noise. In the presence of construction noises in the tank, however, both cod and saithe showed a wider array of behavioural changes, including increased swimming speed, changes in depth distribution and increased yawning frequencies. The results from this case study demonstrate that an underwater renovation with increased noise levels impacts fish behaviour and suggests that underwater noise should be considered during the management of aquatic environments, including public aquaria.
