Most studies on new cancer drugs are based on population-derived data, where the absence of response of a small population may pass unnoticed. Thus, individual longitudinal tracking of cells is important for the future development of efficient cancer treatments. We have used digital holographic microscopy to track individual JIMT-1 human breast cancer cells and L929 mouse fibroblast cultivated in
Cerebellar growth is impeded following very preterm birth in human infants and the observed reduction in cerebellar volume is associated with neurodevelopmental impairment. Decreased levels of circulating insulin-like growth factor 1 (IGF-1) are associated with decreased cerebellar volume. The relationship between preterm birth, circulating IGF-1, and key cell populations supporting cerebellar pro
Local biodiversity can be expected to be similar worldwide if environmental conditions are similar. Here, we hypothesize that tropical ant communities with different types of regional species pools but at similar habitat types in Brazil and Indonesia show similar diversity patterns at multiple spatial scales, when comparing (1) the relative contribution of alpha and beta diversity to gamma diversi
Det är trångt i kön till läkarutbildningen. Därför har Lunds universitet beslutat att utgå från skolbetyg vid antagning till utbildningen och att använda högskoleprovresultat som skiljekriterium vid lika meriter. Det skriver Stefan Lindgren, programdirektör, Lena Sandberg, nämndsekreterare, och Nils Danielsen, ordförande för läkarprogrammet vid Lunds universitet.
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
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
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
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
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
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
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
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
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
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
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 (IUG
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.
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
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
