Vertebrates have evolved an adaptive immune system in addition to the ancestral innate immune system. It is often assumed that a trade-off between costs and benefits of defence governs the evolution of immunological defence, but the costs and benefits specific to the adaptive immune system are poorly known. We used genetically engineered mice lacking lymphocytes (i.e. mice without adaptive, but wi
Spectral-line displacements away from the wavelengths naively expected from the Doppler shift caused by stellar radial motion may originate as convective shifts (correlated velocity and brightness patterns in the photosphere), as gravitational redshifts, or perhaps be induced by wave motions. Absolute lineshifts, in the past studied only for the Sun, are now accessible also for other stars thanks
A multiphase clock generator based on direct phase interpolation is presented. No feedback loop is required. A simple phase interpolation architecture is proposed, in which the two phase-adjacent signals are interpolated by using a series of resistors via inverters' discharging or charging slopes to generate multiphase outputs in a single stage. A phase error averaging circuit is used to correct i
Three properdin deficiency phenotypes have been reported--complete deficiency (type I), incomplete deficiency (type II), and dysfunction of properdin protein (type III)--all associated with increased susceptibility to meningococcal disease. Expression of properdin by monocytes was examined in type I deficiency and in two unrelated cases with type II deficiency, one from a Swedish and one from a Da
High hyperdiploid acute lymphoblastic leukemia (ALL) is one of the most common malignancies in children. It is characterized by gain of chromosomes, typically +X, +4, +6, +10, +14, +17, +18, and +21,+21; little is known about additional genetic aberrations. Approximately 20% of the patients relapse; therefore it is clinically important to identify risk-stratifying markers. We used SNP array analys
OBJECTIVES: The purpose of this study was to determine whether statin treatment is effective and safe in very elderly (80 years and older) acute myocardial infarction (AMI) patients. BACKGROUND: Elderly individuals constitute an increasing percentage of patients admitted to hospitals for AMI. Despite that these patients have a higher mortality risk, the application of evidence-based medicine remai
This longitudinal study used a multi-disciplinary approach and examined the relationship between psychosocial and health characteristics and the pattern of informal and formal support for non-institutionalized very old people. The data were derived from a single cohort of 80-year-old people living in Lund, Sweden who were followed over a 3-year period. In order to account for potential sample bias
Background and Study Aims: Sedation and monitoring practice during colonoscopy varies between centers and over time. Knowledge of current practice is needed to ensure quality of care and help focus future research. The objective of this study was to examine sedation and monitoring practice in endoscopy centers internationally. Patients and Methods: This observational study included consecutive pat
Nuclear magnetic resonance spectroscopy and rheological analysis have been used to investigate the stability of mechanically induced tri-ethylene-glycol-mono-n-decyl-ether (C10E3)/deuterium oxide (D2O) multi-lamellar vesicles (MLVs) and the transition from MLVs to planar lamellae. It was found that MLVs prepared by vortex stirring, relax back to the lamellar phase in a few hours while the relaxati
An analysis of high-resolution near-infrared spectra of a sample of 45 asymptotic giant branch (AGB) stars towards the Galactic bulge is presented. The sample consists of two subsamples, a larger one in the inner and intermediate bulge, and a smaller one in the outer bulge. The data are analysed with the help of hydrostatic model atmospheres and spectral synthesis. We derive the radial velocity of
The purpose of this paper is to contribute with a new understanding of pop-up stores through a phenomenological perspective by examining how consumers experience pop-up stores. The study also aims to look at a micro and macro perspective to better understand how this phenomenon links to and is shaped by macro level trends of the contemporary consumer culture. Given the purpose and aim of the repor
Alla människor har ett värde som ligger i deras egenskap av att vara just människor. Men att vara människa är inte vad vi aktivt blir definierade som utan i första hand kan identiteter såsom ”elev” komma. Syftet med min uppsats är att undersöka huruvida den svenska grundskolan har en fullständig potential till att respektera sina elevers människovärde trots att de främst blir sedda som elever. FörEvery human being has a value in itself solely on the ground that they are human beings. But a human being is not what you are first and foremost defined as, but rather, for example a “pupil”. The purpose of this essay is to examine whether the Swedish elementary school has the full potential of respecting its’ pupils’ human worth. In order to achieve this I have intertwined threads from philosoph
Vår studie visade att det fanns ett samband mellan marknadsandel och lojalitet. Vidare vad gäller sambandet mellan lojalitet och priselasticitet samt pris och lojalitet hittades inget samband eftersom denna var väldigt svag.Our study showed that there is a relationship between market share and loyalty. Regarding the relationship between loyalty and price elasticity and price and loyalty, the study shows a very weak correlation. Thus the conclusion that there is no correlation .
This study seeks to provide an up-to-date analysis of how fandom communities perceive the stadium naming rights phenomenon. In order to gather empirical material which includes both a hypothetical and a retrospective perspective, the research is comprised of two independent cases. Focus groups and semi-structured interviews were the selected data collection methods, while the empirical data was an
This study examines the adaptive capacity of desert farming in Egypt to imminent water scarcity and discusses the sustainability of fossil groundwater extraction. Through qualitative semi-structured expert interviews, the study identifies clear research and data gaps related to the Nubian Sandstone Aquifer System (NSAS) and highlights the need for a nuanced approach to fossil groundwater extractio
The HAMLET family of compounds (Human Alpha-lactalbumin Made Lethal to Tumours) was discovered during studies on the properties of human milk, and is a class of protein-lipid complexes having broad spectrum anti-cancer, and some specific anti-bacterial properties. The structure of HAMLET-like compounds consists of an aggregation of partially unfolded protein making up the majority of the compound'
Ethnographically inspired methods have in recent years been successfully applied in Information Science (IS) research on different forms of social media related practices (c.f. Sundin & Francke 2009a; 2009b, Kjellberg 2010). This paper aims to contribute to an emerging discussion on the use of this methodological approach for analysing and comprehending consequences of the 2.0-turn in public l
Organometal halide perovskite-based solar cells have recently been reported to be highly efficient, giving an overall power conversion efficiency of up to 15%. However, much of the fundamental photophysical properties underlying this performance has remained unknown. Here, we apply photoluminescence, transient absorption, time-resolved terahertz and microwave conductivity measurements to determine
BACKGROUND Tannins can bind to and precipitate protein by forming insoluble complexes resistant to fermentation and with a positive effect on protein utilisation by ruminants. Three protein types, Rubisco, rapeseed protein and bovine serum albumin (a single high-molecular weight protein), were used to test the effects of increasing concentrations of structurally different condensed tannins on prot
Denna studie undersöker den rumsliga variationen i markens koldioxid-utflöde (CO2) i en boreal blandskog, huvudsakligen dominerad av tall (Pinus sylvestris L.) och gran (Picea abies L.) i ADVEX experimentsite i Norunda, centrala Sverige. Mätningar av markens CO2 gjordes i 72 collars omkring huvudtornet med hjälp av en LI-6250 infraröd gasanalysapparat kopplad till en hemmagjord mörkkammare. MedelvThis study investigates the spatial variation in soil carbon dioxide (CO2) efflux in a boreal mixed forest mainly dominated by Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L.) in the ADVEX expermental site in Norunda, in central Sweden. Soil CO2 efflux measurements were performed in 72 collars around the main tower by using a portable LI-6250 infrared gas analyzer connected to a
