Variation in the structure and size of the eye in relation to light environments is well-documented across animal taxa. However, the long-term effects of ultraviolet radiation (UVR) on eye size across generations remain understudied, despite natural fluctuations in UVR being common in aquatic habitats. Here, we used Daphnia magna to test whether an evolutionary history of UVR threat modifies plast
Cupriavidus is a bacterial genus related to Burkholderia, with members that can be negative or positive for us. Some species can give people serious, and even deadly diseases. Among the species positive for us is one that can be used for replacing plastic production from fossil oil by a more sustainable method.
Lineage plasticity is recognized as a critical determinant of lethality and resistance to AR pathway inhibitors in prostate cancer. Lineage plasticity is a continuum, ranging from AR activity-low tumors, AR-null tumors that do not express a neuroendocrine prostate cancer (NEPC) program (i.e., double-negative prostate cancer [DNPC]), and AR-null NEPC tumors. Factors upregulated early in lineage pla
Background: Nonsense-mediated mRNA decay (NMD) is a post-transcriptional RNA surveillance process that facilitates the recognition and destruction of mRNAs bearing premature terminations codons (PTCs). Such PTC-containing (PTC+) mRNAs may arise from different processes, including erroneous processing and expression of pseudogenes, but also from more regulated events such as alternative splicing co
The recent growth in research on "good governance" and the quality of government institutions has been propelled by empirical findings that show that such institutions may hold the key to understanding economic growth and social welfare in developing and transition countries. We argue, however, that a key issue has not been addressed, namely, what quality of government (QoG) actually means at the
Aim: To assess the development of preterm infants from 40 weeks gestational age to 18 months corrected age in order to identify early predictors of later development. Methods: Fifty-one infants were involved. Infant development was assessed at 40 and 44 weeks gestational age with the Brazelton Neonatal Behavioral Assessment Scale and a Self-Regulation Scale and at 3, 6, 10, 18 months corrected age
Aim: To characterize postnatal changes in serum IGF-I in relation to development of bronchopulmonary dysplasia (BPD) in very preterm infants. Methods: Longitudinal study of 108 infants with mean (SD) gestational age 27.2 (2.2) weeks. Weekly serum samples of IGF-I were analyzed from birth until postmenstrual age 36 weeks. Multivariate models were developed to identify independent predictors of
The association of Helicobacter pylori with gastroduodenal diseases is well established. The mode of transmission of the organism is still unclear, although the faecal-oral route has been proposed. H. pylori has been detected in gastric antrum, dental plaques, faeces and water. In the light of these studies we attempted to detect H. pylori in antral biopsies, dental plaques, and stool specimens of
For most neurodegenerative diseases the precise duration of an individual cell's death is unknown, which is an obstacle when counteractive measures are being considered. To address this, we used the rd1 mouse model for retinal neurodegeneration, characterized by phosphodiesterase-6 (PDE6) dysfunction and photoreceptor death triggered by high cyclic guanosinemono-phosphate (cGMP) levels. Using cell
Aerosols are one of the significant factors influencing climate, environment, and human health. They are categorized into anthropogenic and natural sources. In Sweden, natural aerosol sources of high coarse mode particle mass concentrations for particles larger than 1 µm in diameter include sea spray, primary biogenic particles, and dust particles. The dust particles can be agricultural soil and m
Syftet med detta examensarbete är att undersöka vad som får svenska pensionärer att migrera till Costa del Sol och hur det påverkar deras uppfattning om deras existentiella hälsa som uttryckt i mening-i-livet, sammanhang och tillit. Uppsatsen bygger på ett två veckor långt fältarbete, med observationer, samtal och ett kort frågeformulär. Den övergripande forskningsfrågan är hur migrationen har påvThe purpose of this thesis is to investigate what makes Swedish retirees migrate to Costa del Sol and how it affects their perception of their Existential Health as expressed in Meaning-in-life, Coherence and Trust, building on a two-week fieldwork, with observations, free conversations, and a short questionnaire. The overall research question is how the migration has influenced retiree’s percepti
The paper examines the triangluar situations which occur because of the bilateral nature of double tax treaties and tries to find out whether a bilateral tax treaty is able to solve a situation between more than two states. The thesis discusses proposed solutions and assesses their application considering the bilateral nature of the treaties.
The paper presents the theories of Peter Singer and Tom Regan concerning the moral status of animals and why both deem animals to have a moral standing similar to humans. The two theories differ in their approaches to justifying the moral standing of animals and humans but have very similar conclusions. The paper then goes on to show how both theories have potential problems in justifying that the
Previous research in information security research has pointed out the importance of aware employees, while practitioners have focused on technical safety measures, this while the geopolitical situation has rapidly changed. In this paper the public Swedish institutions of higher education are investigated to gain a more complete picture of the potential pitfalls that exist in Swedish government ag
This thesis aims to investigate if there is a monetary cost associated with interstate travel by rail within the European Union and how this differs from intrastate railway travel in the Union. The paper makes use of two economic theories, Transaction cost theory and Ramsey pricing, to help explain the effect we find. A linear regression is applied to our dataset containing 1050 observations and w
The purpose of this study was to explore whether there is a relationship between emotional state and the degree of creative use of grammatical constructions. Based on previous literature on the relationship between mood (used interchangeably with emotional state) and creativity a hypothesis was formulated: Speakers in a more positive mood will be more creative in their use of grammatical construct
We have studied excitation energy transfer in the photosynthetic antenna systems LH1 and LH2 of purple bacteria. Femtosecond pump-probe experiments were combined with computer simulations using the recently established structure of these systems to assess the nature of electronic excitation. We have measured the transient absorption kinetics and spectra of the LH1 and LH2 complexes in the tem
