Vid den nordiska konferensen ”Teaching bioethics” illustrerade transplantationskirurgen Nils H. Persson och jag hur en dialogpedagogisk metod kan belysa en frågeställning på ett sätt som är svårt för en ensam lärare. Nils H. Persson diskuterade bland annat den stora skillnaden i frekvens av organdonationer mellan de nordiska länderna, mindre än 15 PMP (per million population), och Spanien, mer än
In order to increase reuse, a number of product versions may be)", developed based on the same software platform. The platform must, however, be managed and updated according to new requirements if it should be reusable in a series of releases. This means that the platform is constantly changed during its lifecycle, and changes can result in degradation of the platform. In this paper, a measuremen
Energy consumption reduction is today an important design issue for all kinds of digital systems. Offering both flexibility and efficient energy management, variable speed processor architectures are prefered for low energy consumption even in hard real-time systems. For this type of systems, the main approach consists in trading speed for lower energy while meeting all deadlines. For tasks with v
Human pigmentation is a complex phenomenon commonly believed to serve a photoprotective function through the generation and strategic localization of black insoluble eumelanin biopolymers in sun exposed areas of the body. Despite compelling biomedical relevance to skin cancer and melanoma, eumelanin photoprotection is still an enigma: What makes this pigment so efficient in dissipating the excess
Complement components and their cascade of reactions are important defense mechanisms within both innate and adaptive immunity. Many complement deficient patients still remain undiagnosed because of a lack of high throughput screening tools. Aiming towards neonatal proteome screening for immunodeficiencies, we used a multiplex profiling approach with antibody bead arrays to measure 9 complement pr
To date, there have been several detections of high-mass black hole binaries in both the Milky Way and other galaxies. For some of these, the spin parameter of the black hole has been estimated. As many of these systems are quite tight, a suggested origin of the spin is angular momentum imparted by the synchronous rotation of the black hole progenitor with its binary companion. Using Cygnus X-1, t
Antibody array-based technology is a powerful emerging tool in proteomics, but to enable global proteome analysis, antibody array layouts with even higher density has to be developed. To this end, we have further developed the first generation of a nanoarray platform, based on attoliter sized vials, attovials, which we have characterized and used for the detection of complement factor C1q in human
A "complex salt" of cetyltrimethylammonium (CTA(+)) with short (30 repeating units) polyacrylate (PA(-)) counterions has been synthesized. The phase diagrams of its aqueous mixtures with either the surfactant cetyltrimethylammonium acetate (CTAAc), or the polyelectrolyte NaPA, have been studied by visual inspection through crossed polarizers and by small-angle X-ray scattering. Both of the ternary
An indirect 125I-labeled protein A assay for detection of cell surface-bound rat immunoglobulins is presented. The assay is quantitative and rapid and detects as little as 1 ng of cell surface-bound Ig. It discriminates between antibodies belonging to different IgG subclasses, IgM and IgA. We describe the production and specificity control of the reagents used and show that the test can be used fo
The aim of this study was to describe first-time mothers' views of satisfaction with their first encounter with the nurse, in order to investigate differences between home visits and clinic visits and between high/middle and low socioeconomic classification (SEC). A nation-wide postal questionnaire sent to 800 first-time mothers yielded the data for statistical analysis. Data were collected using
OBJECTIVES This study describes changes in high-frequency QRS components (HF-QRS) during percutaneous transluminal coronary angioplasty (PTCA) and compares the ability of these changes in HF-QRS and ST-segment deviation in the standard 12-lead electrocardiogram (ECG) to detect acute coronary artery occlusion. BACKGROUND Previous studies have shown decreased HF-QRS in the frequency range of 150–
In 2006, a cross-sectional survey of 384 randomly selected houses within a community-based follow-up study was conducted to assess the human T-cell lymphotropic virus (HTLV) prevalence in Bissau. Changes in prevalence and incidence rates were assessed based on a similar survey carried out 10 years earlier. The prevalence of HTLV-1 declined significantly from 3.5% in 1996 to 2.3% in 2006. The incid
The distinction between thermodynamic and kinetics in cellulose dissolution is seldom considered in the literature. Therefore, herein an attempt to discuss this topic and illustrate our hypotheses on the basis of simple experiments was made. It is well-known that cellulose can be dissolved in a aqueous sodium hydroxide (NaOH/H2O) solvent at low temperature but it is here shown that such an alkalin
Some concerns still have not been resolved about the long-term safety of drug-eluting stents (DES) in patients with acute STEMI.
Earlier work has shown that pre-B cells can be converted into macrophages by the transcription factor CCAAT/enhancer binding protein a at very high frequencies. Using this system, we performed a systematic analysis of whether during transdifferentiation the cells transiently reactivate progenitor-restricted genes or even retrodifferentiate. A transcriptome analysis of transdifferentiating cells sh
Popular Abstract in Swedish Utifrån epigrafiska källor analyserar avhandlingen Afrodites roll som ämbetsmannabeskyddarinna. Huvudmaterialet är 62 dedikationer till Afrodite: inskrifter från ämbetsmän eller dedikationer där gudinnan presenteras med ett epitet som alluderar på ett ämbete, t.ex. Afrodite Strategis, ‘Strategernas Afrodite’. Materialet visar att Afrodite dyrkades av ämbetsmän på ett paThrough the identification of a series of inscriptions, mainly datable to the Hellenistic era, a link between Aphrodite and the civic life and administration of the Greek poleis has come to light. The inscriptions in question are dedications to Aphrodite through which magistrates of various cities and varying status express their devotion to the goddess. In certain dedications, the goddess is even
