Research review (peer-reviewed)abstract
- Fungi are major ecological players in both terrestrial and aquatic environments by cycling organic matter and channelling nutrients across trophic levels. High-throughput sequencing (HTS) studies of fungal communities are redrawing the map of the fungal kingdom by hinting at its enormous - and largely uncharted - taxonomic and functional diversity. However, HTS approaches come with a range of pitfalls and potential biases, cautioning against unwary application and interpretation of HTS technologies and results. In this Review, we provide an overview and practical recommendations for aspects of HTS studies ranging from sampling and laboratory practices to data processing and analysis. We also discuss upcoming trends and techniques in the field and summarize recent and noteworthy results from HTS studies targeting fungal communities and guilds. Our Review highlights the need for reproducibility and public data availability in the study of fungal communities. If the associated challenges and conceptual barriers are overcome, HTS offers immense possibilities in mycology and elsewhere.

Environmental crises and the metabolic rift in world-historical perspective
- 2000
-
In: Organization & environment. - 1086-0266 .- 1552-7417. ; 13:2, s. 123-157
-
Journal article (peer-reviewed)abstract
- This article proposes a new theoretical framework to study the dialectic of capital and nature over the longue durée of world capitalism. The author proposes that today’s global ecological crisis has its roots in the transition to capitalism during the long sixteenth century. The emergence of capitalism marked not only a decisive shift in the arenas of politics, economy, and society, but a fundamental reorganization of world ecology, characterized by a “metabolic rift,” a progressively deepening rupture in the nutrient cycling between the country and the city. Building upon the historical political economy of Marx, Foster, Arrighi, and Wallerstein, the author proposes a new research agenda organized around the concept of systemic cycles of agro-ecological transformation. This agenda aims at discerning the ways in which capitalism’s relationship to nature developed discontinuously over time as recurrent ecological crises have formed a decisive moment of world capitalist crisis, forcing successive waves of restructuring over long historical time.

Exploring veterinary students' awareness and perception of zoonoses risks, infection control practices, and biosecurity measures in Ethiopia
- 2024
-
In: Frontiers in Veterinary Science. - : Frontiers Media S.A.. - 2297-1769. ; 11
-
Journal article (peer-reviewed)abstract
- Universities and colleges are often regarded as playing a key role in educating veterinarians and animal health workers who advise farmers on herd health and animal husbandry. However, to date, studies examining veterinary students' knowledge of zoonotic diseases of public health importance and the source of this knowledge, as well as their preparedness to respond to these diseases, have focused on the Global North rather than the Global South. This study takes Ethiopia as a case study in exploring veterinary medicine students' knowledge of zoonosis risks, infection control practices and biosecurity measures, recognizing that it is imperative to reconcile national-level veterinary education curricula with emerging global trends, such as One Health-focused training. This training advocates for a collaborative, interdisciplinary response at local, national, and international levels to the adverse impact of zoonotic diseases on animal health and productivity, and human and environmental health. Data for this study were collected through a pre-tested online questionnaire administered to 154 veterinary students from several universities in Ethiopia. The findings of this study suggest veterinary students were aware of the public health risks posed by zoonoses and the important role that collaboration between the disciplines of human and animal health can play in addressing zoonoses and emerging health risks. However, students demonstrated poor knowledge of the need to adopt infection control measures (ICPs) and biosecurity measures to reduce occupational risks and prevent within and between herd transmission of infection. Moreover, students' vaccination rates against zoonotic diseases associated with occupational risks, such as rabies, were low. The results of this study suggest that there are currently gaps in Ethiopia's veterinary curriculum and that enhancing veterinary students' access to information regarding infection control practices and biosecurity measures could contribute to reducing their future occupational exposure to zoonoses. This study highlights the policy implications of the current veterinary medicine curriculum in Ethiopia and the scope for aligning the curriculum with important global initiatives, such as One Health-focused training.

Spatio-temporal modelling of verotoxigenic Escherichia coli O157 in cattle in Sweden: exploring options for control
- 2018
-
In: Veterinary Research. - : Springer Science and Business Media LLC. - 0928-4249 .- 1297-9716. ; 49
-
Journal article (peer-reviewed)abstract
- A spatial data-driven stochastic model was developed to explore the spread of verotoxigenic Escherichia coli O157 (VTEC O157) by livestock movements and local transmission among neighbouring holdings in the complete Swedish cattle population. Livestock data were incorporated to model the time-varying contact network between holdings and population demographics. Furthermore, meteorological data with the average temperature at the geographical location of each holding was used to incorporate season. The model was fitted against observed data and extensive numerical experiments were conducted to investigate the model's response to control strategies aimed at reducing shedding and susceptibility, as well as interventions informed by network measures. The results showed that including local spread and season improved agreement with prevalence studies. Also, control strategies aimed at reducing the average shedding rate were more efficient in reducing the VTEC O157 prevalence than strategies based on network measures. The methodology presented in this study could provide a basis for developing disease surveillance on regional and national scales, where observed data are combined with readily available high-resolution data in simulations to get an overview of potential disease spread in unobserved regions.

Human-Human and Human-Animal Interaction : Some Common Physiological and Psychological Effects
- 2010
-
Doctoral thesis (other academic/artistic)abstract
- The aim of the present thesis was to investigate hormonal and physiological effects in mothers during a breastfeeding session and in dogs and their owners in response to short-term interaction. In study one, sixty-six mothers receiving either exogenous oxytocin infusion and/or epidural analgesia (EDA) during labor or intramuscular oxytocin injection post partum were studied. Oxytocin, prolactin, adrenocorticotrophic hormone (ACTH) and cortisol levels, as well as blood pressure were measured during a breastfeeding session two days after birth. In response to breastfeeding two days after birth, the mothers displayed a pulsatile release of oxytocin and increasing prolactin levels. In addition, the activity in the HPA-axis was reduced and maternal blood pressure decreased. The results also show that EDA administration in combination with oxytocin during labor resulted insignificantly lower oxytocin levels and higher cortisol levels, as well as higher bloodpressure in response to breastfeeding two days after birth, compared to EDA administration alone. In addition, oxytocin infusions dose-dependently lowered the mothers’ endogenous oxytocin levels two days after birth. In study two, ten female dog owners and their male Labrador dogs participated, together with ten controls. Their levels of oxytocin, cortisol and insulin, as well as their heart rate, were measured. The connection between the quality of the dogowner relationship and hormone levels was also explored. Short-term interaction between dogs and their owners resulted in oxytocin release in both species and their cortisol levels and heart rate were also affected. Oxytocin levels and positive attitudes regarding the dog-owner relationship were positively correlated. In conclusion, both human-human and human-animal interactions induce oxytocin release and promote oxytocin mediated effects, such as decreasing cortisol levels and blood pressure. In addition, social interaction and oxytocin levels arepositively related.

Perfluorononanoic acid (PFNA) alters lipid accumulation in bovine blastocysts after oocyte exposure during in vitro maturation
- 2019
-
In: Reproductive Toxicology. - : Elsevier BV. - 0890-6238 .- 1873-1708. ; 84, s. 1-8
-
Journal article (peer-reviewed)abstract
- Perfluorononanoic acid (PFNA) is one of the perfluoroalkyl acids present in human tissues. In this study, effects on early embryo development after PFNA exposure were investigated using the bovine in vitro production system. Oocytes were exposed to PFNA during maturation in vitro (10 μg mL-1 and 0.1 μg mL-1), and then fertilized and cultured in parallel with control groups. Developmental parameters (cleavage, blastocyst formation) were followed and embryo quality evaluated (stage, grade). Embryos developed after exposure to 0.1 μg mL-1 were stained to distinguish nuclei, active mitochondria and neutral lipids. 10 μg mL-1 of PFNA had a severe negative effect on blastocyst formation (OR: 0.27 p < 0.05), an effect not observed at 0.1 μg mL-1. However, lipid droplet distribution was significantly altered in embryos exposed to 0.1 μg mL-1, suggesting a disturbance of lipid metabolism after exposure to sublethal levels of PFNA during oocyte maturation in vitro.

Acute chest pain emergencies : spouses' prehospital experiences
- 2008
-
In: International emergency nursing. - : Elsevier BV. - 1878-013X .- 1755-599X. ; 16:4, s. 233-240
-
Journal article (peer-reviewed)abstract
- The call to the Emergency Medical Dispatch Centre is often a person's first contact with the health-care system in cases of acute illness or injury and acute chest pain is a common reason for calling. The aim was to illuminate how spouses to persons with acute chest pain experienced the alarm situation, the emergency call and the prehospital emergency care. Interviews were conducted with nineteen spouses. A phenomenological-hermeneutic approach was used for the analyses. The themes responsibility and uneasiness emerged as well as an overall theme of aloneness. Being a spouse to a person in need of acute medical and nursing assistance was interpreted as "Being responsible and trying to preserve life" and "Being able to manage the uneasiness and having trust in an uncertain situation." When their partners' life was at risk the spouses were in an escalating spiral of worry, uncertainty, stress, fear of loss, feeling of loneliness and desperation. They had to manage emotional distress and felt compelled to act to preserve life, a challenging situation.

OM FRISKVÅRDSPEDAGOGIK I ARBETSLIVET. : EN O/RÄTTVIS BETRAKTELSE.
- 1993
-
Licentiate thesis (other academic/artistic)abstract
- I fokus för detta arbete står friskvård inom arbetslivet som pedagogisk praktik med hälsoprofilsbedömning, en metod för undersökning och påverkan av människors hälsostatus och hälsovanor, som konkret exempel. En bakgrund till detta är framväxten av insatser för folkhälsa och den ökade betoning av friskvård inom arbetslivet som skett inom såväl privat som offentlig sektor. Friskvård handlar om människors levnadsvanor när det gäller kost, motion, stress, alkohol, tobak m.m.Hälsoprofilsbedömning och friskvårdspedagogik inom arbetslivet ses här ur två olika perspektiv. Ur det ena perspektivet behandlas verksamheten på dess egna villkor - som en metod att inom ramen för arbetslivet få till stånd ner hälsosamma livsstilar genom kontrakt mellan självständiga parter. Det andra perspektivet kan ses som kritiskt granskande. Här ifrågasätts premissema för hälsoprofilsbedömningen utifrån begrepp som makt och disciplinering. En inspirationskälla har därvid bland annat Michel Foucaults arbeten varit. Som empiriskt material för analysen används två avhandlingar som presenterar hälsoprofilbedömningen som metod.Ur dessa båda perspektiv erhålles två olika betraktelser om hälsoprofilsbedömning och friskvårdspedagogik inom arbetslivet - en rättvis och en orättvis. På basis av en kritisk pragmatisk ansats diskuteras möjligheten till ett samtal baserad på relationen mellan de båda betrakelserna.
