BACKGROUND: Perfluoroalkyl substances (PFAS) have been associated with impaired antibody levels after childhood vaccinations and immunosuppressive effects in animals. However, the in vivo effects of PFAS on antigen specific human T cell responses have not been investigated in adults. In Ronneby, Sweden, the drinking water of one of the water works was previously highly contaminated with primarily

Background: Affectivity has been suggested as a complex adaptive meta-system composed of positive affect and negative affect, two independent but interrelated markers of well-being, that can be represented as four distinct affective profiles: self-fulfilling (high positive affect/low negative affect), high affective (high positive affect/high negative affect), low affective (low positive affect/lo

BACKGROUND/PURPOSE: Non-resuscitation fluids constitute the majority of fluid administered for septic shock patients in the intensive care unit (ICU). This multicentre, randomized, feasibility trial was conducted to test the hypothesis that a restrictive protocol targeting non-resuscitation fluids reduces the overall volume administered compared with usual care.METHODS: Adults with septic shock in

Background: Cervical cancer is preventable through screening and vaccination against high-risk human papillomavirus (hr-HPV). For a screening program to be successful it is vital that the clinical management and follow-up regime of patients with abnormal screening results is well developed and that the attendance rate for follow-up is high. The aim of the study was to analyze how effective conizat

The studies were focused on the time period 16.2-10.0 cal ka BP, determined by 36 C-14 dates from the two sequences. A wide variety of proxies were used, including pollen and diatom analyzes, biogenic silica content, C and N analyzes, stabl

PURPOSE. Alzheimer disease (AD) and age-related ocular diseases are characterized by inflammation and accumulation of insoluble proteins. We aimed to investigate the detectability and clinical relevance of a panel of AD-related markers, such as Alzheimer peptides and chemokines, in the aqueous humor (AH) samples taken from patients with cataract only, or cataract and 1 other ocular disease. METHOD

Electrocardiograms are routinely obtained in clinical follow-up of patients with asymptomatic aortic stenosis (AS). The association with aortic valve, left ventricular (LV) response to long-term pressure load, and clinical covariates is unclear and the clinical value is thus uncertain. Data from clinical examination, electrocardiogram, and echocardiogram in 1,563 patients in the Simvastatin and Ez

This thesis concerns a highly efficient nanoparticle-based capillary electrochromatography separation technique and its coupling with mass spectrometric detection. From chromatographic theory, it is well known that the separation efficiency increases with decreasing particle size. However, as the particle size decreases, the pressure required to push a liquid through the column also increases. Thi

The design and analysis of specular radar absorbing materials are investigated throughout the dissertation. Although the topic has been investigated for more than 60 years by many researchers and numerous designs have been proposed, still many technical challenges are remained unanswered. The basic questions are, e.g., the optimal thickness of a design, the possibility of utilization of unconventi

Popular Abstract in Swedish Ateroskleros, ofta kallad åderförkalkning, är en sjukdom som påverkar stora och medelstora artärer såsom aorta, kranskärl, karotis och perifera artärer. Åderförkalkning i kranskärlen orsakar 70 % av dödsfallen hos dessa patienter och räknas som den främsta dödsorsaken i västvärlden. Cerebrovaskulär sjukdom orsakar 20 % av dödsfallen och är den tredje vanligaste dödsorsaAtherosclerosis is the leading cause of death and disability in the western world. Its clinical complications include acute myocardial infarction, sudden death and stroke. Thirty to 40 % of all ischemic strokes are caused by a carotid stenosis. The acute clinical event is triggered by an occluding thrombosis and even more frequently by embolization. Besides the degree of stenosis, the structure of

Popular Abstract in Swedish Sammanväxningar i buken är en normal reaktion efter skador i bukhinnan och utvecklas efter ett inflammatoriskt svar och det efterföljande läkningsförloppet. Många sammanväxningar bildas inom 24-48 timmar efter skadan och tillbakabildas normalt efter 5-7 dagar. Många av de sammanväxningar som kvarstår kan ses som en obalans i de system som bildar ärr (fibros) och löser dIntraabdominal adhesions are formed after most operations and a limited number of studies have to examine the long-term spectrum of adhesion-related disorders and the cost associated with this. Only a few numbers of antiadhesive agents are available which, however, do not decrease the actual morbidity that follows intraabdominal adhesions, such as small bowel obstruction, infertility and pain.

Popular Abstract in Swedish Bakgrund: Det första elektrokardiogrammet (EKG) utfördes 1887 av Augustus Desiré Waller. Det innebar att spänningsskillnader mellan olika delar av hjärtat, under hjärtats arbete dvs. vid upprepade sammandragningar och avslappningar, kunde registreras med elektroder på kroppens yta. Metoden utvecklades vidare av Willem Einthoven, som fick nobelpriset för sitt arbete 1924Background and Methods: Signal-averaging ECG (SAECG), a bioelectrical processing method, is a further development of the conventional ECG. SAECG can detect voltage potentials in the microvolt range and provide a noise-reduced determination of QRS duration. Extended frequency spectra can be analysed. In adult patients after myocardial infarction it is used to predict the risk for arrhythmias and su

Popular Abstract in Swedish Kärnmagnetisk resonans (NMR) är en metod som bygger på att många atomkärnor uppför sig som mycket små magneter. Detta i sin tur beror på att kärnan beter sig som en liten roterande laddning. Man säger att kärnan har ett spinn, eller att kärnan är ett spinn. I min avhandling använder jag mig av en fantastisk egenskap hos kärnspinnen. Om man stör systemet kIn the work presented, nuclear magnetic resonance (NMR) relaxation is used to study wide range of systems. The thesis concerns solvent interactions studied with relaxation techniques that involve measurements at many fields, which allows the separation of individual relaxation mechanisms. The approach also makes it possible to characterize the involved dynamic properties in much greater detail. T

To run a Diesel engine in Homogeneous Charge Compression Ignition (HCCI) mode has proved to be a highly promising approach towards reduced engine-out emissions of NOx and particulate matter. A crucial issue when utilizing HCCI is the degree of charge homogeneity that is required to achieve the desired low temperature combustion. A very well mixed charge can be created through the use of traditiona
