    Ecosystem function in predator-prey food webs: confronting dynamic models with empirical data2019Ingår i: Journal of Animal Ecology, ISSN 0021-8790, E-ISSN 1365-2656, Vol. 88, nr 2, s. 196-210Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Most ecosystem functions and related services involve species interactions across trophic levels, for example, pollination and biological pest control. Despite this, our understanding of ecosystem function in multitrophic communities is poor, and research has been limited to either manipulation in small communities or statistical descriptions in larger ones. Recent advances in food web ecology may allow us to overcome the trade-off between mechanistic insight and ecological realism. Molecular tools now simplify the detection of feeding interactions, and trait-based approaches allow the application of dynamic food web models to real ecosystems. We performed the first test of an allometric food web model's ability to replicate temporally nonaggregated abundance data from the field and to provide mechanistic insight into the function of predation. We aimed to reproduce and explore the drivers of the population dynamics of the aphid herbivore Rhopalosiphum padi observed in ten Swedish barley fields. We used a dynamic food web model, taking observed interactions and abundances of predators and alternative prey as input data, allowing us to examine the role of predation in aphid population control. The inverse problem methods were used for simultaneous model fit optimization and model parameterization. The model captured >70% of the variation in aphid abundance in five of ten fields, supporting the model-embodied hypothesis that body size can be an important determinant of predation in the arthropod community. We further demonstrate how in-depth model analysis can disentangle the likely drivers of function, such as the community's abundance and trait composition. Analysing the variability in model performance revealed knowledge gaps, such as the source of episodic aphid mortality, and general method development needs that, if addressed, would further increase model success and enable stronger inference about ecosystem function. The results demonstrate that confronting dynamic food web models with abundance data from the field is a viable approach to evaluate ecological theory and to aid our understanding of function in real ecosystems. However, to realize the full potential of food web models, in ecosystem function research and beyond, trait-based parameterization must be refined and extended to include more traits than body size. © 2018 The Authors.

    ERP and MEG correlates of visual consciousness: The second decade2020Ingår i: Consciousness and Cognition, ISSN 1053-8100, E-ISSN 1090-2376, Vol. 80, artikel-id 102917Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The first decade of event-related potential (ERP) research had established that the most consistent correlates of the onset of visual consciousness are the early visual awareness negativity (VAN), a posterior negative component in the N2 time range, and the late positivity (LP), an anterior positive component in the P3 time range. Two earlier extensive reviews ten years ago had concluded that VAN is the earliest and most reliable correlate of visual phenomenal consciousness, whereas LP probably reflects later processes associated with reflective/access consciousness. This article provides an update to those earlier reviews. ERP and MEG studies that have appeared since 2010 and directly compared ERPs between aware and unaware conditions are reviewed, and important new developments in the field are discussed. The result corroborates VAN as the earliest and most consistent signature of visual phenomenal consciousness, and casts further doubt on LP as an ERP correlate of phenomenal consciousness.

    The presence and prediction of lateralized inattention 7 years post-stroke2020Ingår i: Acta Neurologica Scandinavica, ISSN 0001-6314, E-ISSN 1600-0404Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: Lateralized inattention is a typical sign of neglect and related to poor functional outcome. Knowledge of the long-term course of this phenomenon is limited. The purpose of this study was to investigate presence and predictors for signs of lateralized inattention 7 years after stroke. Methods: From a cohort of acute ischemic stroke patients, aged 18-69 years (n = 297), a consecutive series of 188 survivors without recurrent stroke at follow-up 7 years later were included. Within the first week after stroke onset, stroke severity was assessed according to the Scandinavian Stroke Scale. Target omissions, asymmetry of omissions, and perceptual speed according to Star- and Letter Cancellation Tests were also assessed. Presence of lateralized inattention at the 7-year follow-up was investigated with the Star- and Letter Cancellation Tests and with the neglect item in the National Institutes of Health Stroke Scale. Results: At the follow-up, 22 (11.7%) participants had lateralized inattention and the multivariable regression showed that independent significant baseline predictors were total omissions in target cancellations (P <.001) and inferior baseline performance on visual processing speed (P =.008). Conclusion: About one of ten individuals exhibited signs of lateralized inattention 7 years after stroke. Baseline performance in perceptual processing speed and target omissions independently predicted presence of late signs of lateralized inattention. This is the first time processing speed is recognized as a significant predictor of lateralized inattention several years after the stroke incidence, indicating that the longitudinal course of processing speed following stroke is a critical subject for future research. © 2020 John Wiley & Sons A/S.

    Human Pluripotent Stem Cell-Derived Hepatocytes Show Higher Transcriptional Correlation with Adult Liver Tissue than with Fetal Liver Tissue2020Ingår i: ACS Omega, ISSN 2470-1343, Vol. 5, nr 10, s. 4816-4827Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Human pluripotent stem cell-derived hepatocytes (hPSC-HEP) display many properties of mature hepatocytes, including expression of important genes of the drug metabolizing machinery, glycogen storage, and production of multiple serum proteins. To this date, hPSC-HEP do not, however, fully recapitulate the complete functionality of in vivo mature hepatocytes. In this study, we applied versatile bioinformatic algorithms, including functional annotation and pathway enrichment analyses, transcription factor binding-site enrichment, and similarity and correlation analyses, to datasets collected from different stages during hPSC-HEP differentiation and compared these to developmental stages and tissues from fetal and adult human liver. Our results demonstrate a high level of similarity between the in vitro differentiation of hPSC-HEP and in vivo hepatogenesis. Importantly, the transcriptional correlation of hPSC-HEP with adult liver (AL) tissues was higher than with fetal liver (FL) tissues (0.83 and 0.70, respectively). Functional data revealed mature features of hPSC-HEP including cytochrome P450 enzymes activities and albumin secretion. Moreover, hPSC-HEP showed expression of many genes involved in drug absorption, distribution, metabolism, and excretion. Despite the high similarities observed, we identified differences of specific pathways and regulatory players by analyzing the gene expression between hPSC-HEP and AL. These findings will aid future intervention and improvement of in vitro hepatocyte differentiation protocol in order to generate hepatocytes displaying the complete functionality of mature hepatocytes. Finally, on the transcriptional level, our results show stronger correlation and higher similarity of hPSC-HEP to AL than to FL. In addition, potential targets for further functional improvement of hPSC-HEP were also identified.

    Probiotic potential of lactic acid bacteria from fresh vegetables: Application in food preservation2019Ingår i: Indian Journal of Experimental Biology, ISSN 0019-5189, E-ISSN 0975-1009, Vol. 57, s. 825-838Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Fresh vegetables are potential source of lactic acid bacteria (LAB). In the present study, LAB were isolated from the fresh vegetables from Pune region. Total 266 LAB were isolated from the edible parts of fresh vegetables viz. cauliflower, gherkins, cluster beans, fenugreek, cow pea, bitter gourd, french beans, tomato, ridged gourd, cucumber and bottle gourd. On phenotypic and molecular characterization predominant genera obtained were Lactobacillus, Enterococcus and Weissella. Twenty one isolates exhibited tolerance to bile salt, acidic pH and pancreatin. Cellular extracts of several isolates with ability to survive in artificial intestinal condition additionally showed antioxidant potential and cell free supernatants xhibited antibacterial potential against selected plant and human pathogens. Bacteriocin and bacteriocin like substances (BLS) substances secreted by these isolates can be used for food preservation.

    Individuals with dark traits have the ability but not the disposition to empathize2020Ingår i: Personality and Individual Differences, ISSN 0191-8869, E-ISSN 1873-3549, Vol. 155, artikel-id 109716Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Empathy is fundamental to social cognition and societal values. Empathy is theorized as having both the ability as well as the disposition to imagine the content of other peoples minds. We tested whether the notorious low empathy in dark personalities (Machiavellianism, psychopathy, and narcissism; the Dark Triad) is best characterized by a lack of capacity (ability) or lack of disposition (trait). Data was collected for 278 international participants through an anonymous online survey shared on the online platform LinkedIn, consisting of trait-based Dark Triad personality (SD3) and empathy (IRI), and cognitive ability (ICAR16) and ability-based empathy (MET). Dark personality traits had no relationship with ability-based empathy, but strongly so with trait-based empathy (beta = -0.47). Instead, cognitive ability explained ability-based empathy (beta = 0.31). The finding is that dark personalities in a community sample is normally cognizant to empathize but has a low disposition to do so. This finding may help shed further light on how personality is interlinked with ability.

    The influence of dexmedetomidine and propofol on circulating cytokine levels in healthy subjects2019Ingår i: BMC Anesthesiology, ISSN 1471-2253, E-ISSN 1471-2253, Vol. 19, nr 1, s. 1-8, artikel-id 222Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Surgery and diseases modify inflammatory responses and the immune system. Anesthetic agents also have effects on the human immune system but the responses they induce may be altered or masked by the surgical procedures or underlying illnesses. The aim of this study was to assess how single-drug dexmedetomidine and propofol anesthesia without any surgical intervention alter acute immunological biomarkers in healthy subjects. Methods: Thirty-five healthy, young male subjects were anesthetized using increasing concentrations of dexmedetomidine (n = 18) or propofol (n = 17) until loss of responsiveness (LOR) was detected. The treatment allocation was randomized. Multi-parametric immunoassays for the detection of 48 cytokines, chemokines and growth factors were used. Concentrations were determined at baseline and at the highest drug concentration for each subject. Results: The changes in the concentration of eotaxin (decrease after dexmedetomidine) and platelet-derived growth factor (PDGF, increase after propofol) were statistically significantly different between the groups. Significant changes were detected within both groups; the concentrations of monocyte chemotactic protein 1, chemokine ligand 27 and macrophage migration inhibitory factor were lower in both groups after the drug administration. Dexmedetomidine decreased the concentration of eotaxin, interleukin-18, interleukin-2Ra, stem cell factor, stem cell growth factor and vascular endothelial growth factor, and propofol decreased significantly the levels of hepatocyte growth factor, IFN-.-induced protein 10 and monokine induced by IFN-gamma, and increased the levels of interleukin-17, interleukin-5, interleukin-7 and PDGF. Conclusions: Dexmedetomidine seemed to have an immunosuppressive effect on the immune system whereas propofol seemed to induce mixed pro- and anti-inflammatory effects on the immune system. The choice of anesthetic agent could be relevant when treating patients with compromised immunological defense mechanisms. Trial registration: Before subject enrollment, the study was registered in the European Clinical Trials database (EudraCT number 2013-001496-21, The Neural Mechanisms of Anesthesia and Human Consciousness) and in ClinicalTrials.gov (Principal Investigator: Harry Scheinin, number NCT01889004, The Neural Mechanisms of Anesthesia and Human Consciousness, Part 2, on the 23rd of June 2013).

    Abstract [sv]

    Döda gråsälar i Östersjön har insamlats och undersökts genom obduktion på Naturhistoriska riksmuseet sedan 1970-talet. En relativt stor andel av de obducerade sälarna har haft sår i tarmarna,och troligen kan perforerade tarmsår vara en av orsakerna till att de har dött. Tarmsåren förorsakas av tre arter av hakmaskar i släktet Corynosoma, och dessa har blivit föremål för ingående morfologiska och ekologiska studier.

    Increased Diagnostic Accuracy of Adnexal Tumors with A Combination of Established Algorithms and Biomarkers2020Ingår i: Journal of clinical medicine, ISSN 2077-0383, Vol. 9, nr 2, artikel-id E299Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Ovarian cancer is the most lethal gynecologic cancer. Pre-diagnostic testing lacks sensitivity and specificity, and surgery is often the only way to secure the diagnosis. Exploring new biomarkers is of great importance, but the rationale of combining validated well-established biomarkers and algorithms could be a more effective way forward. We hypothesized that we can improve differential diagnostics and reduce false positives by combining (a) risk of malignancy index (RMI) with serum HE4, (b) risk of ovarian malignancy algorithm (ROMA) with a transvaginal ultrasound score or (c) adding HE4 to CA125 in a simple algorithm. With logistic regression modeling, new algorithms were explored and validated using leave-one-out cross validation. The analyses were performed in an existing cohort prospectively collected prior to surgery, 2013-2016. A total of 445 benign tumors and 135 ovarian cancers were included. All presented models improved specificity at cut-off compared to the original algorithm, and goodness of fit was significant (p < 0.001). Our findings confirm that HE4 is a marker that improves specificity without hampering sensitivity or diagnostic accuracy in adnexal tumors. We provide in this study "easy-to-use" algorithms that could aid in the triage of women to the most appropriate level of care when presenting with an unknown ovarian cyst or suspicious ovarian cancer.

    Getting Choosy About Whitefish in Lake Vättern: Using Participatory Approaches to Improve Fisheries Selectivity2020Ingår i: Collaborative Research in Fisheries / [ed] Peter Holm, Maria Hadjimichael, Sebastian Linke, Steven Mackinson, Cham: Springer, 2020, s. 43-59Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Our case study was channeled through a comanagement group and initiated by fishermen. The aim was to develop the selectivity of the fisheries in Lake Vättern through a collaboration of fishermen, regional managers, and scientists. The case study was planned collectively within the fisheries co-management group and through workshops with participating fishermen. Fishermen were given special permits to test various strategies adapted to their own experiences and the properties of their local fishing grounds. First, the population structure of the focal species, whitefish, was investigated in a joint study utilizing fishermen’s experiential knowledge and genetic analyses of whitefish. The results showed that the population is divided into at least two unique stocks that ideally should be managed separately. Second, the results from studies on by-catch in different areas, seasons, and gears indicated a substantial potential to increase the selectivity in this fishery, particularly by targeting whitefish aggregations adjacent to spawning areas. Our study highlights the potential of the participatory approach when facilitating solutions to problems related to small-scale fisheries management. Nevertheless, we also identify some factors that might jeopardize the long-term success and dissemination of results from this case study. The recent discovery of high levels of dioxins and dioxin-like PCBs in muscle tissue of whitefish might make it harder for fishermen to sell their catch. Moreover, since the comanagement group only has an advisory function, the Swedish national authority needs to take the initiative and first implement the suggested changes in management.

    Evolutionary Analysis of the Bacillus subtilis Genome Reveals New Genes Involved in Sporulation2020Ingår i: Molecular biology and evolution, ISSN 0737-4038, E-ISSN 1537-1719Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Bacilli can form dormant, highly resistant, and metabolically inactive spores to cope with extreme environmental challenges. In this study, we examined the evolutionary age of Bacillus subtilis sporulation genes using the approach known as genomic phylostratigraphy. We found that B. subtilis sporulation genes cluster in several groups that emerged at distant evolutionary time-points, suggesting that the sporulation process underwent several stages of expansion. Next, we asked whether such evolutionary stratification of the genome could be used to predict involvement in sporulation of presently uncharacterized genes (y-genes). We individually inactivated a representative sample of uncharacterized genes that arose during the same evolutionary periods as the known sporulation genes and tested the resulting strains for sporulation phenotypes. Sporulation was significantly affected in 16 out of 37 (43%) tested strains. In addition to expanding the knowledge base on B. subtilis sporulation, our findings suggest that evolutionary age could be used to help with genome mining.

    Dream affect: Conceptual and Methodological Issues in the Study of Emotions and Moods Experienced in Dreams2020Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    We experience affect—emotions and mood—not only when we are awake but alsoduring dreaming. Despite considerable research, existing theories and empiricalfindings disagree about the frequency, nature, and correlates of dream affect. In thisthesis, I discuss the conceptual and methodological issues that underlie thesediscrepancies. I present five empirical studies, the overall aim of which was toinvestigate the phenomenology and correlates of dream affect and how resultsregarding these are influenced by study methodology. Studies I–III focusedspecifically on methodological issues, by comparing self- and external ratings ofdream affect (Studies I–II) or the affective content of home and laboratory dreamreports (Study III). Studies IV and V investigated the waking well-being and neuralcorrelates of dream affect, respectively. These studies show that results andconclusions regarding dream affect are very different, even contradictory, dependingon whether dream reports have been collected using sleep laboratory awakenings orhome dream diaries (Study III) or whether dream affect has been measured usingself- or external ratings (Studies I–II). Self- and external ratings of dream affect arealso differently correlated with waking well-being (Study IV). Together, theseresults caution against making broad generalizations about affective dreamexperiences from findings obtained with one type of methodology only. The studiesalso demonstrate that dream affect is related to aspects of waking well-being and illbeing(Study IV) and that certain affective states experienced in dreams, specificallyanger, rely on similar neural processes as in wakefulness (Study V). These findingssuggest that the phenomenology and neural correlates of affective experiences are,at least to some extent, continuous across sleep and wakefulness. Overall, this thesisshows how the conceptual and methodological issues in the study of dream affectmay limit the validity, generalizability, and replicability of findings and,consequently, pose challenges to theory building and theory testing. It contributes todream research by highlighting the need, and suggesting ways, to enhance theconceptual clarity and methodological rigour of research on dream affect. Due to theinterdisciplinary nature of the thesis, the theoretical discussion and novel empiricalfindings also have implications for emotion research, sleep research, well-beingresearch, consciousness research, and affective neuroscience.

    Transcriptional sex and regional differences in paired human atrial and ventricular cardiac biopsies collected in vivo2020Ingår i: Physiological Genomics, ISSN 1094-8341, E-ISSN 1531-2267, Vol. 52, nr 2, s. 110-120Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Transcriptional studies of the human heart provide insight into physiological and pathophysiological mechanisms, essential for understanding the fundamental mechanisms of normal cardiac function and how they are altered by disease. To improve the understanding of why men and women may respond differently to the same therapeutic treatment it is crucial to learn more about sex-specific transcriptional differences. In this study the transcriptome of right atrium and left ventricle was compared across sex and regional location. Paired biopsies from five male and five female patients undergoing aortic valve replacement or coronary artery bypass grafting were included. Gene expression analysis identified 620 differentially expressed transcripts in atrial and ventricular tissue in men and 471 differentially expressed transcripts in women. In total 339 of these transcripts overlapped across sex but notably, 281 were unique in the male tissue and 162 in the female tissue, displaying marked sex differences in the transcriptional machinery. The transcriptional activity was significantly higher in atrias than in ventricles as 70% of the differentially expressed genes were upregulated in the atrial tissue. Furthermore, pathway- and functional annotation analyses performed on the differentially expressed genes showed enrichment for a more heterogeneous composition of biological processes in atrial compared with the ventricular tissue, and a dominance of differentially expressed genes associated with infection disease was observed. The results reported here provide increased insights about transcriptional differences between the cardiac atrium and ventricle but also reveal transcriptional differences in the human heart that can be attributed to sex.
