Despite a growing awareness of the presence of cyanobacterial toxins, knowledge about the ability of specific species to produce toxic compounds is still rather limited. It was the overall goal of the current work to investigate if probes derived from the freshwater species Lyngbya aerugineo-coerulea (Kutz.) Gomont, a cyanobacterium frequently found in southern Europe and not previously investigat

Studies assessing the effects of vitamin D or calcium intake on breast cancer risk have been inconclusive. Furthermore, few studies have evaluated them jointly. This study is the largest so far examining the association of dietary vitamin D and calcium intake with breast cancer risk in the European Prospective Investigation into Cancer and Nutrition. During a mean follow-up of 8.8yr, 7760 incident

BACKGROUND: It is well established that parity and use of oral contraceptives reduce the risk of ovarian cancer, but the associations with other reproductive variables are less clear. METHODS: We examined the associations of oral contraceptive use and reproductive factors with ovarian cancer risk in the European Prospective Investigation into Cancer and Nutrition. Among 327 396 eligible women, 878

AQCD analysis is reported of ATLAS data on inclusive W-+/- and Z boson production in pp collisions at the LHC, jointly with ep deep-inelastic scattering data from HERA. The ATLAS data exhibit sensitivity to the light quark sea composition and magnitude at Bjorken x similar to 0:01. Specifically, the data support the hypothesis of a symmetric composition of the light quark sea at low x. The ratio o

The aqueous self-assembly behavior of the dyes Quinaldine red acetate and Pyronin Y in a wide range of concentrations is reported here for the first time. 1H NMR spectroscopy, polarized-light optical microscopy, and small and wide X-ray scattering were used to get insight into molecular interactions, phase boundaries and aggregate structure. Quinaldine red acetate and Pyronin Y self-organize into

Methods: Twenty-seven patients with acute first-time reperfused MI were studied. Infarct size was determined by delayed contrast-enhanced magnetic resonance imaging (DE-MRI) and estimated with the 50-criteria/31-point Selvester QRS scoring system 1 week after admission. The findings in the present study were compared with previous postmortem studies exploring the quantitative relationship between

Macrophages (m phi) are essential for intestinal homeostasis and the pathology of inflammatory bowel disease (IBD), but it is unclear whether discrete m phi populations carry out these distinct functions or if resident m phi change during inflammation. We show here that most resident m phi in resting mouse colon express very high levels of CX3CR1, are avidly phagocytic and MHCII hi, but are resist

Coffee and tea contain numerous antimutagenic and antioxidant components and high levels of caffeine that may protect against colorectal cancer (CRC). We investigated the association between coffee and tea consumption and CRC risk and studied potential effect modification by CYP1A2 and NAT2 genotypes, enzymes involved in the metabolization of caffeine. Data from 477,071 participants (70.2% female)

The aim of this cross-sectional study was to investigate the prevalence of overweight and obesity in children and adolescents (6-16 years), and relationships between being overweight and sleep, experiencing of fatigue, enjoyment of school, and time spent in watching television and in sitting at the computer. Trained school nurses measured the weight and height of 2891 children aged 6, 7, 10, 14, a

This research report has two objectives, both focusing on the supply chain flows passing or crossing the Öresund maritime area. The first objective is to identify and describe the flows in Öresund and the risks for disturbances in those flows before and after the opening of the Öresund Link in July 2000. With the opening of the Öresund Link a new goods and passenger flow was created. As a resul

Popular Abstract in Swedish Proteinkinas C (PKC) är en familj enzymer (protein som påskyndar cellulära förlopp) bestående av åtminstone 10 medlemmar (isoformer) vilka är involverade i ett flertal cellulära processer. Varje isoform är namngiven med en grekisk bokstav och beroende på olika egenskaper hos enzymerna kan PKC familjen delas in i tre undergrupper, de klassiska (α, βΙ, βΙΙ och γ), de nya Protein kinase C (PKC) is a family of serine/threonine kinases subgrouped into classical (α, βI, βII, γ), novel (δ, ε, η, θ) and atypical (ζ, ι/λ) isoforms. PKC can be activated by phorbol esters, and prolonged treatment of neuroblastoma cells has been shown to induce neuronal differentiation with neurite outgrowth and increased expression of neuronal genes. Here we show that a classical PKCβ isof

Förtroende inom outsourcing har granskats av flera forskare under de senaste decennierna. Den här uppsatsen ger en förståelse av faktorer som påverkar förtroende i en outsourcing relation, samt ger en praktisk insikt i hur det ömsesidiga förtroendet mellan kund och leverantör kan förbättras. Det empiriska materialet består av djupintervjuer med experter från olika branscher. Forskningen utgör värdTrust and outsourcing have been a profound object of studies examined by several researchers in the last decades. This thesis offers an understanding of factors that affect trust in an outsourcing relationship as well as it provides practical insight of how to improve mutual trust between client and supplier. The data was gathered through in-depth interviews with experts from different industries.

Within the Renewable Energy Directive, the European Union has embedded sustainability criteria, addressing sustainable biofuels. Due to criticism, the sustainability criteria have been re-examined by the EU in the light of Indirect Land Use Change (ILUC). This thesis focuses on the sustainability understanding of the EU on biofuels, through assessing the sustainability criteria in the realms of su

This thesis explores the causal relationship between exogeneous price shocks on commodities and the level and intensification of violence in the Democratic Republic of the Congo during the year 1989 to 2023. To empirically test this relationship, fixed effects regression models has been used to analyze the effects of these shocks across the 26 provinces that makes up the Democratic Republic of the

The pervasive issue of Per- and polyfluoroalkyl substances (PFAS) motivated the research for this master's thesis. During a previous professional experience at a chemical consultancy, insights were gained into the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulatory requirements, which informed the foundation of this study. PFAS are recognized for being high

On March 11, 2011, a magnitude 9.0 earthquake followed by a 15-meter tsunami and a nuclear accident at Fukushima Daiichi changed the normal course of events in Japan and far beyond it. Among other consequences, the events triggered a sudden increase in domestic and international media coverage. Approaching the theory of media framing, this thesis focused on the evolution of the nuclear energy disc
