Aim: To explore the association between the coagulation protein fibrinogen and the fibrinolytic biomarker plasminogen activator inhibitor-1 ( PAI- 1) and the long- term mortality after coronary artery bypass grafting ( CABG). Patients and Methods: In 729 patients undergoing CABG at Sahlgrenska University Hospital, a blood sample for fibrinogen and PAI-1 was collected prior to the procedure. Patien
Carbon content and indices of microbial biomass and activity were determined in 1985 in different soil horizons of two nitrogen-fertilized pine forests in Sweden. The Kroksbo site was fertilized in 1974 with 150 and 600 kg N•ha−1 using NH4NO3 or urea, while the Nissafors site was fertilized in 1977 and 1984 with 150 kg NH4NO3-N•ha−1 The absolute amount of C per square metre of forest floor increas
The aim was to perform a bibliometric study, and compare the quantity of publications on schizophrenia with the total medical literature in Medline during 57 years, 1950-2006. The annual additions of literature to Medline are continually increasing and form the Medline growth curve. Comparisons of the number of publications on schizophrenia, or any other disease, to this curve, may be used to esti
BACKGROUND: In Crohn's disease high tissue expression and serum levels of chemokines and their receptors are known to correlate with disease activity. Because statins can reduce chemokine expression in patients with coronary diseases, we wanted to test whether this can be achieved in patients with Crohn's disease. METHODOLOGY/PRINCIPAL FINDINGS: We investigated plasma levels of chemokines (CCL2, C
Hepatitis D virus (HDV) is dependent on the presence of hepatitis B virus (HBV) for transmission and replication because of its inability to produce its own coat. It remains unclear whether HDV infection increases the risk of hepatocellular carcinoma. Using the Swedish Hospital Discharge Register and Outpatient Registry, we identified 9160 patients with chronic HBV infection between 1997 and 2008,
Sesquiterpene lactone mix detects contact allergy to these compounds present in the plant family Asteraceae. This marker is present in many baseline series. An additional marker is Compositae mix, which is not present in many baseline series. To investigate whether this allergen should be inserted into the Swedish baseline series, sex dermatology centres representing the Swedish Contact Dermatitis
Total and cause specific mortality and cancer morbidity were studied among 1929 asbestos cement workers with an estimated median cumulative exposure of 2.3 fibre (f)-years/ml (median intensity 1.2 f/ml, predominantly chrysotile). A local reference cohort of 1233 industrial workers and non-case referents from the exposed cohort were used for comparisons. The risk for pleural mesothelioma was signif
Spinach thylakoids were separated into grana core, grana margin, and two different stromal lamella fractions in the absence of detergents. The levels of all light-harvesting chlorophyll a/b-binding (LHC) proteins were determined in all fractions, and were normalised to the amount of Photosystem I (PS I) and Photosystem II (PS II) centres. PS Iβ in the stroma lamellae was found to have a full compl
OBJECTIVES: The referrals of elderly for cardiac surgery are increasing. The aim of this retrospective study is to review the long-term survival and to identify causes of late death in elderly after cardiac surgery. DESIGN: Between 1990 and 1993, 130 octogenarians underwent cardiac surgery in our department. A majority (88%) had elective surgery. One hundred and nine patients (84%) were in New Yor
The purpose of this study is to assess QT interval measurements from the EASI 12-lead ECG as compared to the standard 12-lead ECG. The QT interval was automatically measured in simultaneously recorded standard and EASI 12- lead ECGs, using a validated wavelet-based delineator. The agreement between the two sets of measurements was quantified both on a lead-by-lead basis and a multilead basis. The
The effects of two sympathomimetic drugs on mucociliary activity and mucosal blood flow in the rabbit maxillary sinus were investigated by using a photo-electric technique (mucociliary activity) and laser Doppler flowmetry (blood flow). The responses produced were compared with effects of ligation of the external carotid artery. The alpha 1-agonist phenylpropanolamine (0.1-100 micrograms/kg) had n
Tuvalu, a low-lying Small Island Developing State (SIDS), is projected to face severe challenges due to climate change. Most notably, permanent inundation or the permanent loss of habitable land due to sea-level rise. This thesis investigates how Tuvalu has framed climate change as an existential security threat in its international discourse from 2021 to 2023. Applying an adapted version of secur
Den tekniska utvecklingen innebär nya möjligheter för informationssamhället, men möjliggör även nya kränkningar av den personliga och sexuella integriteten. En samtida utveckling som är ett särskilt tryckande hot mot integriteten är möjligheten att skapa pornografiska deepfakes, AI-genererat pornografiskt material som avbildar en enskild person. Detta arbete utreder i vilken utsträckning den enskiWith technological advancements come new possibilities for the digital age, but also the risk of a new kind of violations of personal and sexual integrity. A recent development that constitutes an especially pressing threat to the integrity of individual persons is the ability to create pornographic deepfakes, AI-generated pornographic material of an individual person. This essay examines to what
In this thesis we analyze the concepts of dependability and dependable systems. We investigate methods of designing and implementing dependable systems, in general, and on the Android operating system. A literature review was carried out with two main goals. Firstly, to gain and be able to spread knowledge of dependability according to both its qualitative and quantitative definitions. Secondly, t
Världen över finns det idag flickor, kvinnor och pojkar som inte får leva ut sin fulla potential, som inte får njuta av sina mänskliga och grundläggande rättigheter och friheter. Människor som förtrycks, utsätts för våld och i värsta fall även berövas livet. Deras brott är att de vill leva sina liv, såsom de själva vill. Hedersrelaterat våld och förtryck är ett angeläget samhällsproblem som angåThere are today people around the world who are not able to live their lives as they want. People who are oppressed, victims of violence and in worst case scenario even killed. Their committed crime is that the want to live their life, just the way they want. Honor related violence and oppression is a problem for the whole society. This paper aims to investigate whether this problem is best foug
Two-factor authentication is the method of combining two so called authentication factors in order to enhance the security of user authentication. An authentication factor is defined as ”Something the user knows, has or is”. Something the user knows is often the traditional username and password, something the user has is something that the user is in physical possession of and something the user
Prehistorical musical instruments have been explored in archaeology more systematically since the 1970s when music archaeology was established as a field of study. The new awareness initially led to studies centred on retrieving musical instruments that had been missed and were now lost in archives. New discoveries, too, are very object-oriented. This master’s thesis ties together individual finds
Moderate exercise is deemed beneficial for cognition due to increase in dopamine concentrations in the basal ganglia. Auditory white noise is beneficial for cognition, mainly for those with lower attentional ability, i.e. for those having lower tonic dopamine concentrations. For individuals with higher attention ability white noise can have a negative effect. In this thesis it was examined whether
