    Periods of converging carbon dioxide emissions from oil combustion in a pre-Kyoto context2016In: Environmental Development, ISSN 2211-4645, E-ISSN 2211-4653, Vol. 19, p. 1-9Article in journal (Refereed)
    Abstract [en]

    This paper examines convergence of carbon dioxide (CO2) emissions caused by oil combustion for a panel of 86 countries considering the importance of analyzing sub-periods separately. The investigation also points at the necessity of choosing a restricted global sample, which takes into account, for instance, that Eastern Bloc countries reacted differently to increasing world crude oil prices than the rest of the world. The analysis builds on examining the β-convergence hypothesis in a neoclassical growth model setting with additional control variables such as emissions from combustion of solid fuels. The results reveal evidence in support of unconditional β-convergence of CO2 emissions intensity due to oil combustion in the restricted sample for the sub-periods 1973–1979 and 1979–1991, while no evidence for convergence was found for the post-1991, pre-Kyoto period. We could not find support for coal substituting technologies.

    Folding of an unfolded protein by macromolecular crowding in vitro2014In: Biochemistry, ISSN 0006-2960, E-ISSN 1520-4995, Vol. 53, no 14, p. 2271-7Article in journal (Refereed)
    Abstract [en]

    Protein folding in vivo takes place in a highly crowded environment. The resulting excluded volume forces are thought to stabilize folded forms of proteins. In agreement, many in vitro studies have shown that the presence of macromolecular crowding agents increases the stability of folded proteins but often by only a few kJ per mol. Although it should not matter at what position in the transition between folded and unfolded forms the effect of crowding is employed, there have been no studies assessing whether excluded volume forces alone can correctly fold polypeptides that are mostly unfolded. However, some studies have indicated that the effect of crowding becomes larger the more destabilized the protein is (but still being folded), suggesting that the crowding effect may be exaggerated for unfolded proteins. To address this question directly, we turned to a destabilized mutant of protein L that is mostly unfolded in water but can be folded upon addition of salt. We find that the effect of 200 mg/mL Dextran 20 on the folding equilibrium constant for unfolded protein L (ΔΔGU ≈ 2 kJ mol(-1)) matches the crowding effects found on the folded wild type protein and the mutant when prefolded by salt. This result indicates that the excluded volume effect is independent of starting protein stability and that crowding can shift the reaction toward the folded form when the polypeptide is in the transition region between folded and unfolded states.

    Family members' experiences of care of the dying in residential care homes where the Liverpool Care Pathway was used2018In: International Journal of Palliative Nursing, ISSN 1357-6321, E-ISSN 2052-286X, Vol. 24, no 4, p. 194-202Article in journal (Refereed)
    Abstract [en]

    Background: Residential care homes (RCHs) are increasingly becoming a common place of death for older people. Aim: The aim of this study was to describe family members' experiences of care of the dying in RCHs where the Liverpool care pathway for the dying patient was used.

    Methods: This study had a descriptive qualitative study design. Fifteen (n=15) individual interviews were analysed using qualitative content analysis.

    Results: The analysis resulted in three themes: being confident in a familiar and warm atmosphere, being involved vs not being involved in end-of-life (EoL) care, and being consoled by witnessing the health professional's endeavour to relieve suffering.

    Significance of results: The results indicated that taking part in a care plan seems to increase family members' feelings of involvement in EoL care. This study also highlights the family members' needs for increased possibilities for EoL discussions with the GP.

    Symptom Relief and Palliative Care during the Last Week of Life among Patients with Heart Failure: A National Register Study2018In: Journal of Palliative Medicine, ISSN 1096-6218, E-ISSN 1557-7740, Vol. 21, no 3, p. 361-367Article in journal (Refereed)
    Abstract [en]

    Background: Heart failure is a disease with high morbidity, mortality, and physical and psychological burden. More knowledge about the care provided for patients with heart failure close to death is needed.

    Objective: The aim was to describe key aspects of palliative care during the last week of life in patients with heart failure, as reported by healthcare professionals.

    Design: This is a national register study.

    Setting/Subjects: The study included 3981 patients with diagnosed heart failure as the underlying cause of death.

    Measurements: Data were obtained from the Swedish Register of Palliative Care, a national quality register that focuses on patients’ last week of life, independent of diagnosis or care setting. The register includes information about care interventions connected with key aspects of palliative care. Data are reported retrospectively by a nurse or physician at the healthcare unit where the patient dies.

    Results: Only 4.2% of patients with heart failure received specialized palliative care. In their last week of life, symptom prevalence was high, validated scales were seldom used, and symptoms were unsatisfactorily relieved. Around one-fifth (17%) of the patients in the study died alone. Less than half of family members had been offered bereavement support (45%). Moreover, one-third (28%) of the patients and more than half (61%) of the family members were reported to have had end-of-life discussions with a physician during the illness trajectory.

    Conclusion: The results indicate inadequate palliative care for patients with heart failure during their last week of life.

    Regio- and Stereoselective Alkylation of Pyridine-N-oxides: Synthesis of Substituted Piperidines and Pyridines.2016In: Organic Letters, ISSN 1523-7060, E-ISSN 1523-7052, Vol. 18, no 24, p. 6228-6231Article in journal (Refereed)
    Abstract [en]

    Regio- and stereoselective addition of alkyl Grignard reagents to pyridine-N-oxides gave C2-alkylated N-hydroxy-1,2,5,6-tetrahydropyridines and trans-2,3-disubstituted N-hydroxy-1,2,5,6-tetrahydropyridines in good to excellent yields. These intermediates were aromatized or alternatively reduced in one-pot methodologies for efficient syntheses of alkylpyridines or piperidines, respectively. These reactions have a broad substrate scope and short reaction times.

    Allopregnanolone and progesterone inestradiol treated severe postpartumdepression and psychosisManuscript (preprint) (Other academic)
    Abstract [en]

    Background

    Postpartum affective disorders may be associated with dysregulation of gonadal steroids. We investigated peripheral levels of allopregnanolone and progesterone in a combined group of women with postpartum onset of severe depression and psychosis who, as previously reported, responded with rapid symptom remission during sublingual estradiol treatment. The aim was to assess differences in allopregnanolone and progesterone between patients and healthy controls at baseline, and hormonal changes during estradiol treatment and symptom remission in patients.

    Methods

    Allopregnanolone and progesterone in serum were analyzed with radioimmunoassay before and four weeks after initiation of sublingual estradiol treatment in ten women with postpartum depression and four women with postpartum psychosis (ICD-10). Twenty-eight healthy postpartum controls were included for baseline comparison.

    Results

    Allopregnanolone declined significantly during estradiol treatment while there was a trend for lower baseline allopregnanolone levels in patients compared with healthy postpartum controls. The ratio between allopregnanolone and progesterone was significantly lower in patients compared with controls and it remained unchanged after clinical recovery.

    Limitations

    This study is a secondary analysis of two estradiol treatment studies based on availability of samples for the analysis of allopregnanolone. Healthy controls were assessed earlier after birth. Data on potential confounders (somatic health, breastfeeding, other medication) were not available.

    Conclusions

    Clinical recovery of severe postpartum depression and psychosis during estradiol treatment does not seem to depend on increasing levels of allopregnanolone. Differences in progesterone metabolism may constitute a risk factor for severe postnatal affective dysregulation.

    Highlights

    - Allopregnanolone decreased during estradiol treatment in postpartum depression and psychosis.

    - The Allopregnanolone/Progesterone ratio was lower in patients compared with controls

    - Change in neurosteroid metabolism may be risk factor for postnatal affective dysregulation

    Plasma oxytocin and personality traits in psychiatric outpatients2015In: Psychoneuroendocrinology, ISSN 0306-4530, E-ISSN 1873-3360, p. 102-110Article in journal (Refereed)
    Abstract [en]

    The oxytocin system is regarded as being of relevance for social interaction. In spite of this, very few studies have investigated the relationship between oxytocin and personality traits in clinical psychiatric populations. We assessed the relationship between personality traits and plasma oxytocin levels in a population of 101 medication-free psychiatric outpatients (men = 37, women = 64). We used the Karolinska Scale of Personality (KSP) and diagnostic and symptomatic testing. Plasma oxytocin levels were analysed with a specific radioimmunoassay at inclusion and after one month for testing of stability. Plasma oxytocin levels were stable over time and did not differ between patients with or without personality disorders, nor were they related to severity of depressive or anxiety symptoms. The KSP factors Impulsiveness and Negative Emotionality were significant independent predictors of plasma oxytocin. A subscale analysis of these personality factors showed significant positive correlations between baseline plasma oxytocin and the KSP subscales monotony avoidance and psychic anxiety. The significant association between the KSP factor Impulsiveness and oxytocin levels observed at baseline was observed also one month later in men. These findings suggest that personality traits such as Impulsiveness and Negative emotionality which are linked to social functioning in several psychiatric disorders seem to be associated with endogenous plasma oxytocin levels. These variations in oxytocin levels might have an impact on social sensitivity or social motivation with possible gender differences.

    Insulin and glucagon in plasma and cerebrospinal fluid in suicide attempters and healthy controls2017In: Psychoneuroendocrinology, ISSN 0306-4530, E-ISSN 1873-3360, Vol. 81, p. 1-7Article in journal (Refereed)
    Abstract [en]

    Mental disorders and related behaviors such as suicidality and violence have been associated to dysregulation of e g carbohydrate metabolism. We hypothesized that patients after suicide attempt, compared to healthy controls, would have higher insulin and lower glucagon levels in plasma and cerebrospinal fluid and that these changes would be associated to violent behavior.

    Twenty-eight medication-free patients (10 women, 18 men), hospitalized after suicide attempt, and 19 healthy controls (7 women, 12 men) were recruited with the aim to study risk factors for suicidal behavior. Psychological/psychiatric assessment was performed with SCID I and II or the SCID interview for healthy volunteers respectively, the Karolinska Interpersonal Violence Scale (KIVS) for assessment of lifetime violence expression behavior, the Montgomery-Åsberg-Depression-Scale (MADRS) and the Comprehensive Psychological Rating Scale (CPRS) for symptomatic assessment of depression and appetite. Fasting levels of insulin and glucagon were measured in plasma (P) and cerebrospinal fluid (CSF).

    Suicide attempters had higher insulin- and lower glucagon-levels in plasma- and CSF compared to controls. Except for P-glucagon these associations remained significant after adjusting for age and/or BMI. Patients reported significantly more expressed interpersonal violence compared to healthy volunteers. Expressed violence was significantly positively correlated with P- and CSF-insulin and showed a significant negative correlation with P-glucagon in study participants. These findings confirm and extend prior reports that higher insulin and lower glucagon levels in plasma and cerebrospinal fluid are associated with suicidal behavior pointing towards a potential autonomic dysregulation in the control of insulin and glucagon secretion in suicidal patients.

    Mosquito control with green nanopesticides: towards the One Health approach? A review of non-target effects2018In: Environmental science and pollution research international, ISSN 0944-1344, E-ISSN 1614-7499, Vol. 25, no 11, p. 10184-10206Article, review/survey (Refereed)
    Abstract [en]

    The rapid spread of highly aggressive arboviruses, parasites, and bacteria along with the development of resistance in the pathogens and parasites, as well as in their arthropod vectors, represents a huge challenge in modern parasitology and tropical medicine. Eco-friendly vector control programs are crucial to fight, besides malaria, the spread of dengue, West Nile, chikungunya, and Zika virus, as well as other arboviruses such as St. Louis encephalitis and Japanese encephalitis. However, research efforts on the control of mosquito vectors are experiencing a serious lack of eco-friendly and highly effective pesticides, as well as the limited success of most biocontrol tools currently applied. Most importantly, a cooperative interface between the two disciplines is still lacking. To face this challenge, we have reviewed a wide number of promising results in the field of green-fabricated pesticides tested against mosquito vectors, outlining several examples of synergy with classic biological control tools. The non-target effects of green-fabricated nanopesticides, including acute toxicity, genotoxicity, and impact on behavioral traits of mosquito predators, have been critically discussed. In the final section, we have identified several key challenges at the interface between "green" nanotechnology and classic biological control, which deserve further research attention.

    Patienters erfarenheter av livet efter att ha drabbats av stroke: en kvalitativ litteraturstudie2021Student thesis
    Abstract [sv]

    Patienters erfarenheter av livet efter att ha drabbats av stroke – en kvalitativ litteraturstudie

    Abstrakt 

    Bakgrund: I Sverige drabbades omkring 25700 personer av stroke 2019. Ungefär 70% av de som överlever stroke drabbas av komplikationer som t.ex. trötthet, depression, smärta, fysiska komplikationer, svårigheter med att läsa, skriva, tala och minnesstörningar vilket kan leda till andra konsekvenser som t.ex. försämrad självständighet, förändrad identitet och social förlust.

     

    Syfte: Att beskriva patienters erfarenheter av livet efter att de drabbats av stroke.

     

    Metod: En kvalitativ litteraturstudie innehållande 12 artiklar som hittades genom sökningar i databaserna Cinahl och Pubmed analyserades med Fribergs femstegsmodell. 

     

    Resultat: Tre kategorier och 10 subkategorier identifierades. De tre kategorierna var: “Uppleva förlust”, “Sträva efter kontroll” och “Våga möta andra människor”. 

     

    Konklusion: Patienter som drabbats av en stroke upplever många utmaningar med både en förändrad kropp, förmåga att utföra meningsfulla aktiviteter, förändrade sociala roller och möjligheten att leva självständigt. Utmaningarna och komplikationer är ofta kopplade till en försämrad hälsa men acceptans och framsteg i återhämtning kan med tiden bidra till en förbättrad hälsa.

    Knowledge flows in high-impact firms: how does relatedness influence survival, acquisition and exit?2016In: Journal of Economic Geography, ISSN 1468-2702, E-ISSN 1468-2710, Vol. 16, no 3, p. 637-665Article in journal (Refereed)
    Abstract [en]

    Following the impact on regional renewal and employment ascribed to rapidly growing firms (high-impactfirms, HIFs), this paper argues that little is still known in economic geography and business studies todayregarding the mechanisms influencing growth of such firms and, hence, the potential impact on regionalemployment. The aim of this paper is thus to explore how the qualitative content of skills (i.e. the degree ofsimilarity, relatedness and unrelatedness) recruited to a firm during a period of fast growth influences itsfuture success. Our findings, based on a sample of 1,589 HIFs in the Swedish economy, suggest that it is notonly the number of people employed that matters in aiding the understanding of the future destiny of the firms– but also, more importantly, it is the scope of the skills recruited and their proximity to related industries.

    Workplace Skill Investments - An Early Career Glass Ceiling?: Job Complexity and Wages Among Young Professionals in Sweden2018In: Work, Employment and Society, ISSN 0950-0170, E-ISSN 1469-8722, Vol. 32, no 2, p. 368-386Article in journal (Refereed)
    Abstract [en]

    Despite higher educational investments, women fall behind men on most indicators of labour market success. This study investigates whether workplace skill investments set men and women off on different tracks in which the human capital acquired through higher education is either devalued or further developed. A survey sample of Swedish men and women who recently graduated from five educational programmes, leading to occupations with different gender composition, is analysed (N approximate to 2300). Results show that, a few years after graduation, men are more likely than women to acquire complex jobs and that this difference contributes to early career gender gaps in wages and employee bargaining power. The findings do not support the notion that child-related work interruptions provide a main mechanism for sorting women into less complex jobs.

    Health-Sector Responses to Intimate Partner Violence: Fitting the Response Into the Biomedical Health System or Adapting the System to Meet the Response?2018In: Journal of Interpersonal Violence, ISSN 0886-2605, E-ISSN 1552-6518, Vol. 33, no 10, p. 1653-1678Article in journal (Refereed)
    Abstract [en]

    This study aims to analyze how middle-level health systems' managers understand the integration of a health care response to intimate partner violence (IPV) within the Spanish health system. Data were obtained through 26 individual interviews with professionals in charge of coordinating the health care response to IPV within the 17 regional health systems in Spain. The transcripts were analyzed following grounded theory in accordance with the constructivist approach described by Charmaz. Three categories emerged, showing the efforts and challenges to integrate a health care response to IPV within the Spanish health system: IPV is a complex issue that generates activism and/or resistance, The mandate to integrate a health sector response to IPV: a priority not always prioritized, and The Spanish health system: respectful with professionals' autonomy and firmly biomedical. The core category, Developing diverse responses to IPV integration, crosscut the three categories and encompassed the range of different responses that emerge when a strong mandate to integrate a health care response to IPV is enacted. Such responses ranged from refraining to deal with the issue to offering a women-centered response. Attempting to integrate a response to nonbiomedical health problems as IPV into health systems that remain strongly biomedicalized is challenging and strongly dependent both on the motivation of professionals and on organizational factors. Implementing and sustaining changes in the structure and culture of the health care system are needed if a health care response to IPV that fulfills the World Health Organization guidelines is to be ensured.

    Neurophysiological effects in cortico-basal ganglia-thalamic circuits of antidyskinetic treatment with 5-HT1A receptor biased agonists2018In: Experimental Neurology, ISSN 0014-4886, E-ISSN 1090-2430, Vol. 302, p. 155-168Article in journal (Refereed)
    Abstract [en]

    Recently, the biased and highly selective 5-HT1A agonists, NLX-112, F13714 and F15599, have been shown to alleviate dyskinesia in rodent and primate models of Parkinson's disease, while marginally interfering with antiparkinsonian effects of levodopa. To provide more detailed information on the processes underlying the alleviation of dyskinesia, we have here investigated changes in the spectral contents of local field potentials in cortico-basal ganglia-thalamic circuits following treatment with this novel group of 5-HT1A agonists or the prototypical agonist, 8-OH-DPAT. Dyskinetic symptoms were consistently associated with 80 Hz oscillations, which were efficaciously suppressed by all 5-HT1A agonists and reappeared upon co-administration of the antagonist, WAY100635. At the same time, the peak-frequency of fast 130 Hz gamma oscillations and their cross-frequency coupling to low-frequency delta oscillations were modified to a different extent by each of the 5-HT1A agonists. These findings suggest that the common antidyskinetic effects of these drugs may be chiefly attributable to a reversal of the brain state characterized by 80 Hz gamma oscillations, whereas the differential effects on fast gamma oscillations may reflect differences in pharmacological properties that might be of potential relevance for non-motor symptoms.

    A synbiotic-containing amino-acid-based formula improves gut microbiota in non-IgE-mediated allergic infants2018In: Pediatric Research, ISSN 0031-3998, E-ISSN 1530-0447, Vol. 83, no 3, p. 677-686Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:

    Prebiotics and probiotics (synbiotics) can modify gut microbiota and have potential in allergy management when combined with amino-acid-based formula (AAF) for infants with cow's milk allergy (CMA).

    METHODS: This multicenter, double-blind, randomized controlled trial investigated the effects of an AAF-including synbiotic blend on percentages of bifidobacteria and Eubacterium rectale/Clostridium coccoides group (ER/CC) in feces from infants with suspected non-IgE-mediated CMA. Feces from age-matched healthy breastfed infants were used as reference (healthy breastfed reference (HBR)) for primary outcomes. The CMA subjects were randomized and received test or control formula for 8 weeks. Test formula was a hypoallergenic, nutritionally complete AAF including a prebiotic blend of fructo-oligosaccharides and the probiotic strain Bifidobacterium breve M-16V. Control formula was AAF without synbiotics.

    RESULTS: A total of 35 (test) and 36 (control) subjects were randomized; HBR included 51 infants. At week 8, the median percentage of bifidobacteria was higher in the test group than in the control group (35.4% vs. 9.7%, respectively; P<0.001), whereas ER/CC was lower (9.5% vs. 24.2%, respectively; P<0.001). HBR levels of bifidobacteria and ER/CC were 55% and 6.5%, respectively.

    CONCLUSION: AAF including specific synbiotics, which results in levels of bifidobacteria and ER/CC approximating levels in the HBR group, improves the fecal microbiota of infants with suspected non-IgE-mediated CMA.

    New Mobilities - New Economies?: Temporary populations and local innovation capacity in sparsely populated areas2016In: Settlements at the Edge: Remote human settlements in developed nations / [ed] Andrew Taylor, Dean B. Carson, Prescott C. Ensign, Lee Huskey, Rasmus O. Rasmussen, Gertrude Saxinger, Cheltenham: Edward Elgar Publishing , 2016, p. 178-206Chapter in book (Refereed)
    Abstract [en]

    Temporary population mobilities – including short-term labour, residential and recreational mobilities – have long been a prominent feature of human geography in sparsely populated areas. Such mobilities are often considered from a problem-centric perspective, with both academic and public discourses focusing extensively on the negative impacts that temporary populations have on local communities. Yet, temporary mobilities may also have a range of positive impacts, as they bring new people, ideas, skills, knowledge and network connections to remote communities, and thus potentially contribute to processes of local innovation. This chapter examines how different types of temporary populations contribute to local innovation capacity and new socio-economic development in remote communities. We propose a framework for analysing how different mobile populations with their particular temporal, spatial, motivational and interactional mobility characteristics impact on various forms of community capital, and subsequent innovation outcomes through the mobilisation of such capital. We then apply the framework to review five common examples of temporary mobilities in northern Scandinavia and Outback Australia, ranging from voluntary international lifestyle migrants to displaced refugee migrants, from seasonal second home-owners to short-term transit tourists, and from service to leisure-oriented Indigenous travellers. The review suggests that temporary populations offer substantial potential to boost innovation and new socio-economic development in remote communities, but that communities and institutional structures often fail to recognise and capitalise on such potential.

    Atmospheric nitrogen deposition on petals enhances seed quality of the forest herb Anemone nemorosa2018In: Plant Biology, ISSN 1435-8603, E-ISSN 1438-8677, Vol. 20, no 3, p. 619-626Article in journal (Refereed)
    Abstract [en]
    • Elevated atmospheric input of nitrogen (N) is currently affecting plant biodiversity and ecosystem functioning. The growth and survival of numerous plant species is known to respond strongly to N fertilisation. Yet, few studies have assessed the effects of N deposition on seed quality and reproductive performance, which is an important life-history stage of plants.
    • Here we address this knowledge gap by assessing the effects of atmospheric N deposition on seed quality of the ancient forest herb Anemone nemorosa using two complementary approaches.
    • By taking advantage of the wide spatiotemporal variation in N deposition rates in pan-European temperate and boreal forests over 2years, we detected positive effects of N deposition on the N concentration (percentage N per unit seed mass, increased from 2.8% to 4.1%) and N content (total N mass per seed more than doubled) of A.nemorosa seeds. In a complementary experiment, we applied ammonium nitrate to aboveground plant tissues and the soil surface to determine whether dissolved N sources in precipitation could be incorporated into seeds. Although the addition of N to leaves and the soil surface had no effect, a concentrated N solution applied to petals during anthesis resulted in increased seed mass, seed N concentration and N content.
    • Our results demonstrate that N deposition on the petals enhances bioaccumulation of N in the seeds of A.nemorosa. Enhanced atmospheric inputs of N can thus not only affect growth and population dynamics via root or canopy uptake, but can also influence seed quality and reproduction via intake through the inflorescences.

    Risk factors for cutaneous leishmaniasis in the rainforest of Bolivia: a cross-sectional study2018In: Tropical Medicine and Health, ISSN 1348-8945, E-ISSN 1349-4147, Vol. 46, article id 9Article in journal (Refereed)
    Abstract [en]

    Background: Cutaneous leishmaniasis (CL) is an endemic disease in Bolivia, particularly in the rainforest of Cochabamba, in the municipality of Villa Tunari. The precarious, dispersed, and poorly accessible settlements in these farming communities make it difficult to study them, and there are no epidemiological studies in the area. The aim of the present study was to identify the risk factors associated with cutaneous leishmaniasis.

    Methods: A cross-sectional study was conducted in August 2015 and August 2016 in two communities of Villa Tunari, Cochabamba. The cases were diagnosed through clinical examinations, identification of the parasite by microscopic examination, and the Montenegro skin test. Risk factors were identified through logistic regression.

    Results: A total of 274 participants (40.9% female and 59.1% male) were surveyed, of which 43% were CL positive. Sex was the only factor associated with CL with three times more risk for men than for women; this finding suggests a sylvatic mechanism of transmission in the area.

    Conclusions: It is advisable to focus on education and prevention policies at an early age for activities related to either leisure or work. Further research is needed to assess the influence of gender-associated behavior for the risk of cutaneous leishmaniasis.

    Ethylene signaling induces gelatinous layers with typical features of tension wood in hybrid aspen2018In: New Phytologis, Vol. 218, no 3, p. 999-1014Article in journal (Refereed)
    Abstract [en]
    • The phytohormone ethylene impacts secondary stem growth in plants by stimulating cambial activity, xylem development and fiber over vessel formation.
    • We report the effect of ethylene on secondary cell wall formation and the molecular connection between ethylene signaling and wood formation. We applied exogenous ethylene or its precursor 1-aminocyclopropane-1-carboxylic acid (ACC) to wild-type and ethylene-insensitive hybrid aspen trees (Populus tremulaxtremuloides) and studied secondary cell wall anatomy, chemistry and ultrastructure. We furthermore analyzed the transcriptome (RNA Seq) after ACC application to wild-type and ethylene-insensitive trees.
    • We demonstrate that ACC and ethylene induce gelatinous layers (G-layers) and alter the fiber cell wall cellulose microfibril angle. G-layers are tertiary wall layers rich in cellulose, typically found in tension wood of aspen trees. A vast majority of transcripts affected by ACC are downstream of ethylene perception and include a large number of transcription factors (TFs). Motif-analyses reveal potential connections between ethylene TFs (Ethylene Response Factors (ERFs), ETHYLENE INSENSITIVE 3/ETHYLENE INSENSITIVE3-LIKE1 (EIN3/EIL1)) and wood formation.
    • G-layer formation upon ethylene application suggests that the increase in ethylene biosynthesis observed during tension wood formation is important for its formation. Ethylene-regulated TFs of the ERF and EIN3/EIL1 type could transmit the ethylene signal.

    Attenuating Listeria monocytogenes Virulence by Targeting the Regulatory Protein PrfA.2016In: Cell chemical biology, ISSN 2451-9456, Vol. 23, no 3, p. 404-14, article id S2451-9456(16)30049-6Article in journal (Refereed)
    Abstract [en]

    The transcriptional activator PrfA, a member of the Crp/Fnr family, controls the expression of some key virulence factors necessary for infection by the human bacterial pathogen Listeria monocytogenes. Phenotypic screening identified ring-fused 2-pyridone molecules that at low micromolar concentrations attenuate L. monocytogenes cellular uptake by reducing the expression of virulence genes. These inhibitors bind the transcriptional regulator PrfA and decrease its affinity for the consensus DNA-binding site. Structural characterization of this interaction revealed that one of the ring-fused 2-pyridones, compound 1, binds at two separate sites on the protein: one within a hydrophobic pocket or tunnel, located between the C- and N-terminal domains of PrfA, and the second in the vicinity of the DNA-binding helix-turn-helix motif. At both sites the compound interacts with residues important for PrfA activation and helix-turn-helix formation. Ring-fused 2-pyridones represent a new class of chemical probes for studying virulence in L. monocytogenes.

    Dose painting of prostate cancer based on Gleason score correlations with apparent diffusion coefficients2018In: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 57, no 5, p. 574-581Article in journal (Refereed)
    Abstract [en]

    Background: Gleason scores for prostate cancer correlates with an increased recurrence risk after radiotherapy (RT). Furthermore, higher Gleason scores correlates with decreasing apparent diffusion coefficient (ADC) data from diffusion weighted MRI (DWI-MRI). Based on these observations, we present a formalism for dose painting prescriptions of prostate volumes based on ADC images mapped to Gleason score driven dose-responses.

    Methods: The Gleason score driven dose-responses were derived from a learning data set consisting of pre-RT biopsy data and post-RT outcomes for 122 patients treated with a homogeneous dose to the prostate. For a test data set of 18 prostate cancer patients with pre-RT ADC images, we mapped the ADC data to the Gleason driven dose-responses by using probability distributions constructed from published Gleason score correlations with ADC data. We used the Gleason driven dose-responses to optimize dose painting prescriptions that maximize the tumor control probability (TCP) with equal average dose as for the learning sets homogeneous treatment dose.

    Results: The dose painting prescriptions increased the estimated TCP compared to the homogeneous dose by 0–51% for the learning set and by 4–30% for the test set. The potential for individual TCP gains with dose painting correlated with increasing Gleason score spread and larger prostate volumes. The TCP gains were also found to be larger for patients with a low expected TCP for the homogeneous dose prescription.

    Conclusions: We have from retrospective treatment data demonstrated a formalism that yield ADC driven dose painting prescriptions for prostate volumes that potentially can yield significant TCP increases without increasing dose burdens as compared to a homogeneous treatment dose. This motivates further development of the approach to consider more accurate ADC to Gleason mappings, issues with delivery robustness of heterogeneous dose distributions, and patient selection criteria for design of clinical trials.

    Structural basis for glutathione-mediated activation of the virulence regulatory protein PrfA in Listeria.2016In: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 113, no 51, p. 14733-14738Article in journal (Refereed)
    Abstract [en]

    Infection by the human bacterial pathogen Listeria monocytogenes is mainly controlled by the positive regulatory factor A (PrfA), a member of the Crp/Fnr family of transcriptional activators. Published data suggest that PrfA requires the binding of a cofactor for full activity, and it was recently proposed that glutathione (GSH) could fulfill this function. Here we report the crystal structures of PrfA in complex with GSH and in complex with GSH and its cognate DNA, the hly operator PrfA box motif. These structures reveal the structural basis for a GSH-mediated allosteric mode of activation of PrfA in the cytosol of the host cell. The crystal structure of PrfAWT in complex only with DNA confirms that PrfAWT can adopt a DNA binding-compatible structure without binding the GSH activator molecule. By binding to PrfA in the cytosol of the host cell, GSH induces the correct fold of the HTH motifs, thus priming the PrfA protein for DNA interaction.

    Returning to work: regional determinants of re-employment after major redundancies2018In: Regional studies, ISSN 0034-3404, E-ISSN 1360-0591, Vol. 52, no 6, p. 768-780Article in journal (Refereed)
    Abstract [en]

    Using matched employer-employee data on roughly 429,000 workers made redundant from large plant closures or major downsizing in Sweden between 1990 and 2005, this paper analyses the role of the regional industry mix (specialization, related and unrelated variety) in the likelihood of returning to work. The results show that a high presence of same or related industries speeds up the re-employment process, while high concentrations of unrelated activities do not. The role of related activities is particularly evident in the short run and in regions with high unemployment. Consequently, the prospect of successful diversification is enhanced in regions with related industries.

    Intervening with care: varying outcomes of a training and development programme in elderly care in Sweden2017In: Journal of Vocational Education and Training, ISSN 1363-6820, E-ISSN 1747-5090, Vol. 69, no 4, p. 617-636Article in journal (Refereed)
    Abstract [en]

    Awareness of the mechanisms underlying training and development (T&D) programmes is crucial in creating sustainable learning conditions in organisations. The organisational and psychosocial aspects of the work environment in Swedish elderly care is the focus of this longitudinal study, and the relation between process and results of a T&D programme is investigated. A mixed-methods design enabled exploration of the content of the quality improvement efforts, followed by an examination of how aspects of the work environment are influenced. The perceived learning climate, workload and resource adequacy are shown to be influenced differently by different contents. Insights into the complexity surrounding T&D programmes are then offered. It is concluded that even if a seemingly sound method of quality improvement is implemented, this is not enough to guarantee success. Also, it is apparent that changes may sometimes be at the expense of employees' work environment, which may hamper continuous learning.

    New forest owners: Change and continuity in the characteristics of Swedish non-industrial private forest owners (NIPF owners) 1990-20102016In: Small-scale Forestry, ISSN 1873-7617, E-ISSN 1873-7854, Vol. 15, no 4, p. 533-550Article in journal (Refereed)
    Abstract [en]

    This paper presents a total survey of the characteristics and changes over time (1990–2010) within the entire population of Swedish non-industrial private forest owners (NIPF owners). By charting the changed demographic, socio-economic and geographic profile of the NIPF owners, it also provides a baseline for a discussion and analysis of potential implications for forest management, policy and values. NIPF owners differ in important ways from the general population of Sweden. However, the gap has narrowed over time with regard to, e.g., educational level and sex composition. The ongoing urbanization process is evident in the growing share of non-residential NIPF owners who live at a distance from their forest property and who differ from their residential (rural) peers through, e.g., higher education, higher income and a higher prevalence of co-ownership of their forest holdings. Although these changes might translate into updated views on forest values among NIPF owners, there could be a delay before this impacts on forest management practices and output.

    'Not a Problem Until it Becomes a Problem': A Qualitative Study of Values and Risks of In-house Family Ties in Swedish Workplaces2016In: Nordic Journal of Working Life Studies, ISSN 2245-0157, E-ISSN 2245-0157, Vol. 6, no 4, p. 67-86Article in journal (Refereed)
    Abstract [en]

    In-house family ties at workplaces occur in most contexts, and are associated with both advantages and disadvantages. On the basis of 40 interviews with human resource managers at Swedish workplaces, the values and risks of in-house family ties and their importance within the workplace are analyzed jointly, thus allowing for a holistic perspective. The interviews reveal values and risks on a strategic level, for day-to-day operations, for the social work environment, and on the level of individuals. Crucially, even when in-house family ties are perceived as uncomplicated, there is a latent risk that problems might arise. The interpretation of the role of in-house family ties is also strongly related to whether they are paired with asymmetrical (vertical) power relations. It also depends heavily on the chosen perspective-that of the organization, the social work environment, the individual, or the broader society-and the perceived advantages tend to come with corresponding inverted disadvantages.

    Cost of antenatal care for the health sector and for households in Rwanda2018In: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 18, article id 262Article in journal (Refereed)
    Abstract [en]

    Background: Rwanda has made tremendous progress in reduction of maternal mortality in the last twenty years. Antenatal care is believed to have played a role in that progress. In late 2016, the World Health Organization published new antenatal care guidelines recommending an increase from four visits during pregnancy to eight contacts with skilled personnel, among other changes. There is ongoing debate regarding the cost implications and potential outcomes countries can expect, if they make that shift. For Rwanda, a necessary starting point is to understand the cost of current antenatal care practice, which, according to our knowledge, has not been documented so far.

    Methods: Cost information was collected from Kigali City and Northern province of Rwanda through two cross-sectional surveys: a household-based survey among women who had delivered a year before the interview (N = 922) and a health facility survey in three public, two faith-based, and one private health facility. A micro costing approach was used to collect health facility data. Household costs included time and transport. Results are reported in 2015 USD.

    Results: The societal cost (household + health facility) of antenatal care for the four visits according to current Rwandan guidelines was estimated at $160 in the private health facility and $44 in public and faith-based health facilities. The first visit had the highest cost ($75 in private and $21 in public and faith-based health facilities) compared to the three other visits. Drugs and consumables were the main input category accounting for 54% of the total cost in the private health facility and for 73% in the public and faith-based health facilities.

    Conclusions: The unit cost of providing antenatal care services is considerably lower in public than in private health facilities. The household cost represents a small proportion of the total, ranging between 3% and 7%; however, it is meaningful for low-income families. There is a need to do profound equity analysis regarding the accessibility and use of antenatal care services, and to consider ways to reduce households' time cost as a possible barrier to the use of antenatal care.

    Transition from wakefield generation to soliton formation2018In: Physical review. E, ISSN 2470-0045, E-ISSN 2470-0053, Vol. 97, no 4, article id 043204Article in journal (Refereed)
    Abstract [en]

    It is well known that when a short laser pulse propagates in an underdense plasma, it induces longitudinal plasma oscillations at the plasma frequency after the pulse, typically referred to as the wakefield. However, for plasma densities approaching the critical density, wakefield generation is suppressed, and instead the EM-pulse (electromagnetic pulse) undergoes nonlinear self-modulation. In this article we have studied the transition from the wakefield generation to formation of quasi-solitons as the plasma density is increased. For this purpose we have applied a one-dimensional relativistic cold fluid model, which has also been compared with particle-in-cell simulations. A key result is that the energy loss of the EM-pulse due to wakefield generation has its maximum for a plasma density of the order 10% of the critical density, but that wakefield generation is sharply suppressed when the density is increased further.

    Clinical Cell Therapy Guidelines for Neurorestoration (IANR/CANR 2017)2018In: Cell Transplantation, ISSN 0963-6897, E-ISSN 1555-3892, Vol. 27, no 2, p. 310-324Article, review/survey (Refereed)
    Abstract [en]

    Cell therapy has been shown to be a key clinical therapeutic option for central nervous system diseases or damage. Standardization of clinical cell therapy procedures is an important task for professional associations devoted to cell therapy. The Chinese Branch of the International Association of Neurorestoratology (IANR) completed the first set of guidelines governing the clinical application of neurorestoration in 2011. The IANR and the Chinese Association of Neurorestoratology (CANR) collaborated to propose the current version "Clinical Cell Therapy Guidelines for Neurorestoration (IANR/CANR 2017)". The IANR council board members and CANR committee members approved this proposal on September 1, 2016, and recommend it to clinical practitioners of cellular therapy. These guidelines include items of cell type nomenclature, cell quality control, minimal suggested cell doses, patient-informed consent, indications for undergoing cell therapy, contraindications for undergoing cell therapy, documentation of procedure and therapy, safety evaluation, efficacy evaluation, policy of repeated treatments, do not charge patients for unproven therapies, basic principles of cell therapy, and publishing responsibility.

    An Experimental Performance Evaluation of Autoscalers for Complex Workflows2018In: ACM Transactions on Modeling and Performance Evaluation of Computing Systems (TOMPECS), ISSN 2376-3639, Vol. 3, no 2, article id UNSP 8Article in journal (Refereed)
    Abstract [en]

    Elasticity is one of the main features of cloud computing allowing customers to scale their resources based on the workload. Many autoscalers have been proposed in the past decade to decide on behalf of cloud customers when and how to provision resources to a cloud application based on the workload utilizing cloud elasticity features. However, in prior work, when a new policy is proposed, it is seldom compared to the state-of-the-art, and is often compared only to static provisioning using a predefined quality of service target. This reduces the ability of cloud customers and of cloud operators to choose and deploy an autoscaling policy, as there is seldom enough analysis on the performance of the autoscalers in different operating conditions and with different applications. In our work, we conduct an experimental performance evaluation of autoscaling policies, using as application model workflows, a popular formalism for automating resource management for applications with well-defined yet complex structures. We present a detailed comparative study of general state-of-the-art autoscaling policies, along with two new workflow-specific policies. To understand the performance differences between the seven policies, we conduct various experiments and compare their performance in both pairwise and group comparisons. We report both individual and aggregated metrics. As many workflows have deadline requirements on the tasks, we study the effect of autoscaling on workflow deadlines. Additionally, we look into the effect of autoscaling on the accounted and hourly based charged costs, and we evaluate performance variability caused by the autoscaler selection for each group of workflow sizes. Our results highlight the trade-offs between the suggested policies, how they can impact meeting the deadlines, and how they perform in different operating conditions, thus enabling a better understanding of the current state-of-the-art.

    Examining drivers of sustainable consumption: the influence of norms and opinion leadership on electric vehicle adoption in Sweden2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 154, p. 176-187Article in journal (Refereed)
    Abstract [en]

    Transportation accounts for a large and growing part of carbon dioxide emissions. With an increasing vehicle fleet worldwide private car use is becoming an acute problem in need of urgent attention and action. Policy interference and cleaner cars are not enough; alternative fuel vehicles such as electric vehicles need to be adopted by consumers as well. Previous research on pro-environmental consumer behavior and sustainable consumption has proven the importance of norms and pro-environmental attitudes. However, little research has focused on understanding interpersonal influence found influential in consumer behavior research relating to innovation adoption. Consumer opinion leading and opinion seeking are two such interpersonal influence attitudinal constructs that have not been empirically analyzed in relation to sustainable consumption and alternative fuel vehicles. The main aim of this study is thus to analyze the influence of a set of attitudinal constructs on electric and flexfuel vehicle adoption: personal norms, social norms, ecological attitudes, opinion leading, and opinion seeking. Data from a questionnaire survey on three groups of electric vehicle adopters and non-adopters is used (N=1,192). The results confirm the importance of personal norms, opinion leading and opinion seeking in the three groups also when controlling for socio-demographic factors. The main contribution of this study is that it shows the importance of both interpersonal influence and attitudinal factors as drivers for eco-innovation adoption. The study also contributes in showing that electric vehicle and flexfuel vehicle adopters differ in relation to non-adopters on several factors.

    Elongator-a tRNA modifying complex that promotes efficient translational decoding2018In: Biochimica et Biophysica Acta. Gene Regulatory Mechanisms, ISSN 1874-9399, E-ISSN 1876-4320, Vol. 1861, no 4, p. 401-408Article in journal (Refereed)
    Abstract [en]

    Naturally occurring modifications of the nucleosides in the anticodon region of tRNAs influence their translational decoding properties. Uridines present at the wobble position in eukaryotic cytoplasmic tRNAs often contain a 5-carbamoylmethyl (ncm(5)) or 5-methoxycarbonylmethyl (mcm(5)) side-chain and sometimes also a 2-thio or 2'-O-methyl group. The first step in the formation of the ncm5 and mcm5 side-chains requires the conserved six-subunit Elongator complex. Although Elongator has been implicated in several different cellular processes, accumulating evidence suggests that its primary, and possibly only, cellular function is to promote modification of tRNAs. In this review, we discuss the biosynthesis and function of modified wobble uridines in eukaryotic cytoplasmic tRNAs, focusing on the in vivo role of Elongator-dependent modifications in Saccharomyces cerevisiae. This article is part of a Special Issue entitled: SI: Regulation of tRNA synthesis and modification in physiological conditions and disease edited by Dr. Boguta Magdalena.

    Responses of eight boreal flat bug (Heteroptera: Aradidae) species to clear-cutting and forest fire2010In: Journal of Insect Conservation, ISSN 1366-638X, E-ISSN 1572-9753, Vol. 14, no 1, p. 3-9Article in journal (Refereed)
    Abstract [en]

    Boreal flat bugs include a high proportion of species that are considered negatively affected by forestry. Knowledge on the biology and habitat demands of individual species is generally limited. We examined the influence on flat bugs of stand-age and clear-cutting, comparing five classes of spruce stands. The five classes were: clear-cut, unthinned, and thinned (all three products of current clear-cutting forestry), mature managed and old-growth stands (these two had never been clear-cut). We also compared unburned and recently burned mature pine forest. Fire, but not stand age, had a pronounced effect on species richness and total abundance. Aradus depressus showed a significant association with older forest stands. Aradus betulae occurred only in clear-cuts and burned forest indicating that this species is favored by disturbance in general. Aradus lugubris, Aradus crenaticollis and Aradus brevicollis were found only in the burned forest. Aradus brevicollis has not previously been shown to be associated with fire. © Springer Science+Business Media B.V. 2009.

    Instability and thermal conductivity of pressure-densified and elastically altered orientational glass of Buckminsterfullerene2018In: Journal of Chemical Physics, ISSN 0021-9606, E-ISSN 1089-7690, Vol. 148, no 14, article id 144502Article in journal (Refereed)
    Abstract [en]

    We report on the temperature, pressure, and time (T, p, and t)-dependent features of thermal conductivity, kappa, of partially ordered, non-equilibrium state of C-60-OG, the orientational glass of Buckminsterfullerene (at T below the orientational freezing temperature T-og) made more unstable (i) by partially depressurizing its high-p formed state to elastically expand it and (ii) by further pressurizing that state to elastically contract it. The sub-T-og effects observed on heating of C-60-OG differ from those of glasses because phonon propagation depends on the ratio of two well-defined orientational states of C-60 molecules and the density of the solid. A broad peak-like feature appears at T near T-og in the kappa-T plots of C-60-OG formed at 0.7 GPa, depressurized to 0.2 GPa and heated at 0.2 GPa, which we attribute to partial overlap of the sub-T-og and T-og features. A sub-T-og local minimum appears in the kappa-T plots at T well below T-og of C-60-OG formed at 0.1 GPa, pressurized to 0.5 GPa and heated at 0.5 GPa and it corresponds to the state of maximum disorder. Although Buckminsterfullerene is regarded as an orientationally disordered crystal, variation of its properties with T and p is qualitatively different from other such crystals. We discuss the findings in terms of the nature of its disorder, sensitivity of its rotational dynamics to temperature, and the absence of the Johari-Goldstein relaxation. All seem to affect the phenomenology of its glass-like transition.

    Regenerative effects of human embryonic stem cell-derived neural crest cells for treatment of peripheral nerve injury2018In: Journal of Tissue Engineering and Regenerative Medicine, ISSN 1932-6254, E-ISSN 1932-7005, Vol. 12, no 4, p. E2099-E2109Article in journal (Refereed)
    Abstract [en]

    Surgical intervention is the current gold standard treatment following peripheral nerve injury. However, this approach has limitations, and full recovery of both motor and sensory modalities often remains incomplete. The development of artificial nerve grafts that either complement or replace current surgical procedures is therefore of paramount importance. An essential component of artificial grafts is biodegradable conduits and transplanted cells that provide trophic support during the regenerative process. Neural crest cells are promising support cell candidates because they are the parent population to many peripheral nervous system lineages. In this study, neural crest cells were differentiated from human embryonic stem cells. The differentiated cells exhibited typical stellate morphology and protein expression signatures that were comparable with native neural crest. Conditioned media harvested from the differentiated cells contained a range of biologically active trophic factors and was able to stimulate in vitro neurite outgrowth. Differentiated neural crest cells were seeded into a biodegradable nerve conduit, and their regeneration potential was assessed in a rat sciatic nerve injury model. A robust regeneration front was observed across the entire width of the conduit seeded with the differentiated neural crest cells. Moreover, the up-regulation of several regeneration-related genes was observed within the dorsal root ganglion and spinal cord segments harvested from transplanted animals. Our results demonstrate that the differentiated neural crest cells are biologically active and provide trophic support to stimulate peripheral nerve regeneration. Differentiated neural crest cells are therefore promising supporting cell candidates to aid in peripheral nerve repair.

    Combining Polygenic Hazard Score With Volumetric MRI and Cognitive Measures Improves Prediction of Progression From Mild Cognitive Impairment to Alzheimer's Disease2018In: Frontiers in Neuroscience, ISSN 1662-4548, E-ISSN 1662-453X, Vol. 12, article id 260Article in journal (Refereed)
    Abstract [en]

    Improved prediction of progression to Alzheimer's Disease (AD) among older individuals with mild cognitive impairment (MCI) is of high clinical and societal importance. We recently developed a polygenic hazard score (PHS) that predicted age of AD onset above and beyond APOE. Here, we used data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) to further explore the potential clinical utility of PHS for predicting AD development in older adults with MCI. We examined the predictive value of PHS alone and in combination with baseline structural magnetic resonance imaging (MRI) data on performance on the Mini-Mental State Exam (MMSE). In survival analyses, PHS significantly predicted time to progression from MCI to AD over 120 months (p = 1.07e-5), and PHS was significantly more predictive than APOE alone (p = 0.015). Combining PHS with baseline brain atrophy score and/or MMSE score significantly improved prediction compared to models without PHS (three-factor model p = 4.28e-17). Prediction model accuracies, sensitivities and area under the curve were also improved by including PHS in the model, compared to only using atrophy score and MMSE. Further, using linear mixed-effect modeling, PHS improved the prediction of change in the Clinical Dementia Rating—Sum of Boxes (CDR-SB) score and MMSE over 36 months in patients with MCI at baseline, beyond both APOE and baseline levels of brain atrophy. These results illustrate the potential clinical utility of PHS for assessment of risk for AD progression among individuals with MCI both alone, or in conjunction with clinical measures of prodromal disease including measures of cognitive function and regional brain atrophy.
