Metabolites of Avena sativa with Blood Cholesterol Lowering Properties

Popular Science SummaryOat is one of the cereals that has been increasing in popularity during the last years. Oats are usually consumed for breakfast as a porridge, muesli, bread, or oat drinks which are included in, for example, smoothies. But why is it important to consume oats?There are two types of cholesterol, bad cholesterol and good cholesterol. The bad cholesterol can build up plaque insiCardiovascular diseases are among the most important causes of death in thedeveloped countries. These diseases are partly caused by too high cholesterolconcentrations in the blood. Avena sativa, oat, is the most common spieces of the genus Avena, and produced in huge amounts worldwide. Oats have been shown to have cholesterol-lowering properties since the 1960s. This property was originally attrib

Modelling and simulation of a coal-fired power plant for start-up optimisation

The increased impact from fluctuating energy sources like wind and photovoltaics significantly affects the operational regime of conventional power plants. In the near future, even former base load power plants such as the large-scale lignite plants in Germany will need to start and shut down to balance the electricity system. As frequent starts were not in the focus of optimisation in the past, a

Selfiekulturen i sociala medier

Fotograferandet är en av alla de otaliga praktiker som i grunden har förändrats med digitaliseringen och de sociala medierna. Tidigare fotograferade folk företrädesvis i samband med högtider och semesterresor och bilderna hamnade i det privata familjealbumet. Idag bär vi ständigt med oss kameran i mobiltelefonen och knäpper bilder som aldrig förr, vilket har lett till en ”avsakralisering” och ett

Situating Faculty Development in the Clinical Workplace

Medical students’ access to clinical supervision when rotating through hospital workplaces and the quality of that supervision are and have been an area of growing professional and societal concern. Increased training measures targeted at supervising physicians have been suggested to address this issue. Traditionally, such training has focused on offering physicians opportunities to develop as sup

High-Flow-Rate Impinger for the Study of Concentration, Viability, Metabolic Activity, and Ice-Nucleation Activity of Airborne Bacteria

The study of airborne bacteria relies on a sampling strategy that preserves their integrity and in situ physiological state, e.g. viability, cultivability, metabolic activity, and ice-nucleation activity. Because ambient air harbors low concentrations of bacteria, an effective bioaerosol sampler should have a high sampling efficiency and a high airflow. We characterize a high-flow-rate impinger wi

Hygrothermal assessment of internally added thermal insulation on external brick walls in Swedish multifamily buildings

Proper and efficient renovation requires understanding the behavior of existing buildings and of different building materials. Analyzing hygrothermal measurements in two case studies, one with and the other without an internally added thermal insulation system, enabled us to identify factors of critical importance for further assessment through simulations, and to validate a hygrothermal simulatio

Agnostus pisiformis — a half a billion-year old pea-shaped enigma

The Cambrian arthropod Agnostus pisiformis (Wahlenberg, 1818) is not only a beautiful fossil animal, approximately 1 cm in length when adult, but also an extinct species unusually well-known from its ‘soft’ ventral cuticular structures. It is moreover very useful for biostratigraphic correlation and has a long research history. The species occurs in huge numbers, and in all developmental stages, i

Cortical movement of Bicoid in early Drosophila embryos is actin- and microtubule-dependent and disagrees with the SDD diffusion model

The Bicoid (Bcd) protein gradient in Drosophila serves as a paradigm for gradient formation in textbooks. The SDD model (synthesis, diffusion, degradation) was proposed to explain the formation of the gradient. The SDD model states that the bcd mRNA is located at the anterior pole of the embryo at all times and serves a source for translation of the Bicoid protein, coupled with diffusion and unifo

Medical students’ views of clinical environments

Background: Monitoring the quality of clinical learning environments (CLEs) is immensely important in medical education. Objective indicators of the quality of the CLE can be used to measure learner perceptions and to inform educational improvements; however, many established tools were not designed for use in clinical settings and are not theoretically grounded. Our aim was to apply a new tool to

Polyphagy and diversification in tussock moths : Support for the oscillation hypothesis from extreme generalists

Theory on plasticity driving speciation, as applied to insect–plant interactions (the oscillation hypothesis), predicts more species in clades with higher diversity of host use, all else being equal. Previous support comes mainly from specialized herbivores such as butterflies, and plasticity theory suggests that there may be an upper host range limit where host diversity no longer promotes divers

Heavy metals exposure levels and their correlation with different clinical forms of fetal growth restriction

Background: Prenatal heavy metals exposure has shown a negative impact on birth weight. However, their influence on different clinical forms of fetal smallness was never assessed. Objectives: To investigate whether there is a differential association between heavy metals exposure and fetal smallness subclassification into intrauterine growth restriction (IUGR) and small-for-gestational age (SGA).

Police perspectives on road safety and transport politics in Germany

Road safety is a key concern of transport governance. In the European Union, a Road Safety Programme was adopted in 2011, with the objective to reduce road deaths in Europe by 50% in the period from 2011 to 2020. Evidence suggests, however, that this goal will not be met. Against this background, this paper investigates police perspectives on traffic laws, traffic behaviour, and transport policy.

Characterization of thermal neutron beam monitors

Neutron beam monitors with a wide range of efficiencies, low γ sensitivity, and high time and space resolution are required in neutron beam experiments to continuously diagnose the delivered beam. In this work, commercially available neutron beam monitors have been characterized using the R2D2 beamline at IFE (Norway) and using a Be-based neutron source. For the γ sensitivity measurements differen

The impact of experts on tax policy in post-war Britain and Sweden

During the decades after World War II, countries began shifting taxation from income to consumption. This shift has been associated with an expanding welfare state and left-wing dominance. However, the pattern is far from uniform and while some left-wing governments indeed expanded consumption taxation, others did not. This paper seeks to explain why, by exploring how experts influenced post-war t

Pituitary adenylate cyclase-activating polypeptide and islet amyloid polypeptide in primary sensory neurons : Functional implications from plasticity in expression on nerve injury and inflammation

Primary sensory neurons serve a dual role as afferent neurons, conveying sensory information from the periphery to the central nervous system, and as efferent effectors mediating, e.g., neurogenic inflammation. Neuropeptides are crucial for both these mechanisms in primary sensory neurons. In afferent functions, they act as messengers and modulators in addition to a principal transmitter; by relea

Building public trust in compensation programs through accuracy assessments of damage verification protocols

Reliable verification of damage claims is fundamental to create public trust in the legitimacy of compensation programs, and avoid fraud and moral hazards. However, after decades of using this tool, transparency in verification processes and availability of quantitative information on the accuracy and misidentification rates are unresolved issues. Accurate rules overcome several challenges facing

Counting thin subgraphs via packings faster than meet-in-the-middle time

Vassilevska and Williams (STOC'09) showed how to count simple paths on k vertices and matchings on k/2 edges in ann-vertex graph in time nk/2+O(1). In the same year, two different algorithms with the same runtime were given by Koutis and Williams (ICALP'09), and Bjorklund et al. (ESA'09), via nst/2+O(1)-time algorithms for counting t-tuples of pairwise disjoint sets drawn from a given family of s-

Feasibility of reusing time-matched controls in an overlapping cohort

The methods developed for secondary analysis of nested case-control data have been illustrated only in simplified settings in a common cohort and have not found their way into biostatistical practice. This paper demonstrates the feasibility of reusing prior nested case-control data in a realistic setting where a new outcome is available in an overlapping cohort where no new controls were gathered
