Lichen symbiosis has been traditionally treated as a model case of mutualism in which both partners, the fungus and the photobiont. gain benefits reciprocally. Some recent evidence, however, supports an alternative view that lichen symbiosis may represent an association largely controlled by the commensal or even parasitic fungal partner. The latter gains photosynthates from the photobiont (algae
Carbon content and indices of microbial biomass and activity were determined in 1985 in different soil horizons of two nitrogen-fertilized pine forests in Sweden. The Kroksbo site was fertilized in 1974 with 150 and 600 kg N•ha−1 using NH4NO3 or urea, while the Nissafors site was fertilized in 1977 and 1984 with 150 kg NH4NO3-N•ha−1 The absolute amount of C per square metre of forest floor increas
Fetal mesencephalic mouse tissue, rich in dopamine neurons, was xenografted as a dissociated cell suspension into the striatum of rats with unilateral 6-hydroxydopamine induced lesions of the mesostriatal pathway. The rats were either assigned to a 10-day, 21-day or 42-day Cyclosporin A (CyA) immunosuppression scheme, or given no immunosuppression. The functional effects of the grafts were followe
Urban societies are increasingly affected by climatic variability and extremes. In theory, adaptation policy creates the conditions needed to support autonomous adaptation – or deliver public adaptation if autonomous adaptation fails to develop. However, little attention has been given to autonomous adaptation by private households and individuals, and how it is taken into account in cities’ strat
Digital research data is often advanced as a trouble-free concept and used to describe the material of research at all stages in a research process. However frequently such framing lacks understanding of the roles of disciplinary and organisational cultures, and of what the various practices, including those of funding policy and university administration, involved in shaping what research data ar
Reactive oxygen species (ROS) are thought to contribute to the secondary injury process after traumatic brain injury (TBI). ROS scavenging compounds have shown neuroprotective properties in various models of experimental brain injury, including TBI. Administration of nitrone radical scavengers has emerged as a promising pharmacological concept in focal experimental ischemia due to their low toxici
The International Working Group on the Diabetic Foot appointed an expert panel to provide evidence-based guidance on the management of osteomyelitis in the diabetic foot. Initially, the panel formulated a consensus scheme for the diagnosis of diabetic foot osteomyelitis (DFO) for research purposes, and undertook a systematic review of the evidence relating to treatment. The consensus diagnostic sc
AIM OF THE STUDY: : To investigate the effects of early intravenous adrenaline administration on circulatory recovery, cerebral reoxygenation, and plasma catecholamine concentrations, after severe asphyxia-induced bradycardia and hypotension. METHODS: One-day old piglets were left in apnoea until heart rate and mean arterial pressure were less than 50min(-1) and 25mmHg, respectively. They random

Brevmall A. Reading course: Machine Learning Techniques in Social Science (PhD level), 7,5 hp A third level (PhD) “reading course” does not involve any teaching and typically only has one or a few participants taking part in the course. A reading course for 7,5 credits should cover an ambitious and demanding reading material, which exact page number can vary depending on the nature of texts (i.e.,

This paper aims to examine whether competition law and policies have greater effect on competition when sound institutions are in place. Reports by major global actors as well as governmental reforming, show that there is unanimity on the notion that political reforming is essential in order to reach a more competitive market. Later economic research shows that institutions such as governance effe
Understanding, monitoring and mitigating drought is a very difficult task as a consequence of the intrinsic nature of the phenomenon. In addition, assessing the impact of drought on ecosystems and societies is also a complex task, because the same drought severity may have different consequences in different regions and systems due to the underlying vulnerabilities. New technologies based on geosp
Several unmet needs have been identified in allergic rhinitis: identification of the time of onset of the pollen season, optimal control of rhinitis and comorbidities, patient stratification, multidisciplinary team for integrated care pathways, innovation in clinical trials and above all patient empowerment. MASK-rhinitis (MACVIA-ARIA Sentinel NetworK for allergic rhinitis) is a simple system cent
Interest in monoclonal antibody aggregation is increasing as aggregates of biopharma-ceuticals can cause an immunogenic response when injected into the body. In this work a stoichiometric reaction model from concentration-time data is developed to predict the dimer ratio in stored antibody solutions over time. IgG1 was incubated at pH from 4.5 to 5.5, salt concentrations from 100 to 600 mmol/kg an
Background: Ultrasound-guided transvaginal oocyte retrieval is often performed under local anaesthesia on an outpatient basis. The objective of this study was to compare the overall pain experience of a newly designed reduced needle (RN) compared with a thicker standard needle (SN). Methods: A prospective, randomized, multi-centre study was performed at four different clinics from June to December
The solar proxy Be-10, measured in natural archives, has previously been assumed to lag solar activity by 1-2 yr. This reflects its residence time in the stratosphere where its main source lies. This study, based on a 30-yr global model simulation of the atmospheric transport of Be-10, shows that the stratospheric fraction of production varies significantly with the phase of solar activity. This l
