Objective. Accurate and reproducible assessment of myocardial infarction is important for treatment planning in patients with ischemic heart disease. This study describes a novel method to quantify myocardial infarction by semi-automatic delineation of hyperenhanced myocardium in delayed contrast enhanced (DE) magnetic resonance (MR) images. Design. The proposed method automatically detects the hy
Provitamin D2, vitamin D2 and vitamin D3 were identified in the thallus of a lichen species, Cladina arbuscula (Wallr.) Hale and W.L. Culb. The identification of vitamin D3 was supported by: (1) co-chromatography in both reverse and straight phase HPLC (high performance liquid chromatography), (2) ultraviolet absorption spectrum, and (3) molecular ion peaks demonstrated by ESI (electrospray ionisa
The recycling heparan sulfate (HS)-containing proteoglycan glypican-1 (Gpc-1) is processed by nitric oxide (NO)-catalyzed deaminative cleavage of its HS chains at N-unsubstituted glucosamines. This generates anhydromannose (anMan)-containing HS degradation products that can be detected by a specific antibody. Here we have attempted to identify the intracellular compartments where these products ar
The Davies transformation is a method to transform the steering vector of a uniform circular array (UCA) to one with Vandermonde form. As such, it allows techniques such as spatial smoothing for direction-of-arrival (DOA) estimation in a correlated signal environment, developed originally for uniform linear arrays, to be applied to UCAs. However, the Davies transformation can be highly sensitive t
Context: Previous in vitro studies have demonstrated that the UDP glucuronosyltransferase (UGT) 2B15 and UGT2B17 glucuronidate androgens and their metabolites. Objective: Our objective was to determine in vivo whether the UGT2B15 (DY)-Y-85 and the UGT2B17 deletion polymorphisms predict androgen glucuronidation and body composition. Participants: Two population-based cohorts including young adult (
High-spin states in the mass A~60 region were populated using the state-of-art gamma-ray spectrometers Gammasphere, Euroball, and GASP in conjunction with dedicated ancillary detectors. In particular, the 59Cu nucleus was studied in several experiments, and a very extensive level scheme was determined. It comprises more than 320 transitions connecting about 150 excited states. Relative to mass, it
The coagulum proteins of human semen, semenogelins I and II, are secreted in abundance by the seminal vesicles. Their function in reproduction is poorly understood as they are rapidly degraded in ejaculated semen. However, more recent results indicate that it is time to put the semenogelins in a broader physiological perspective that goes beyond reproduction and fertility.
Approximately 5 to 7% of patients with hemophilia A have inhibitory antibodies to factor (F) VIII, which increases to similar to 13% in patients with severe disease. The strongest determinant of the risk of inhibitor development identified is the type of mutation in the FVIII gene that gives rise to the disease. However, accumulating evidence clearly indicates that other genetic factors (e.g., maj
As more and more applications and services in our society now depend on the Internet, it is important that dynamically deployed wireless multi hop networks are able to gain access to the Internet and other infrastructure networks and services. This thesis proposes and evaluates solutions for providing multi hop Internet Access. It investigates how ad hoc networks can be combined with wireless and
The opportunities of using hydrophobic pervaporation to concentrate organic components in aroma recovery and wastewater treatment have been recognized widely. The focus of this article is on the influence of the support layer on the mass transfer in hydrophobic pervaporation. Even though the influence of the support layer on the overall mass transfer has been observed experimentally, the modeling
Although interactions in biological systems occur in the presence of a large number of charged species, the binding of charged ligands to different biomolecules is often analyzed in a simplified model focusing only upon the receptor, ligand, and added salt. Here we demonstrate that the presence of charged macromolecules can affect binding to the receptor in an unexpected way. Experimental studies
We compare different procedures for combining fixed-order tree-level matrix element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare different implementations of the so-called CKKW scheme and one based on the so-called MLM scheme using different matrix element generators and different parton cascades. We find that although similar results are o

Genomic DNA from each of four Acl individuals (genotypes AO1, AO1var, AO2) and one AclB individual was used as a template for amplifying exons 6 and 7 of the ABO genes, which were subsequently sequenced. In all the Ael alleles a single nucleotide insertion, compared to the A consensus sequence, was observed that would alter the amino acid sequence of the glycosyltransferase immediately after its p
Patch-clamp recordings and glucagon release measurements were combined to determine the role of plasma membrane ATP-sensitive K+ channels (K-ATP channels) in the control of glucagon secretion from mouse pancreatic alpha-cells. In wild-type mouse islets, glucose produced a concentration-dependent (half-maximal inhibitory concentration [IC50] = 2.5 mmol/l) reduction of glucagon release. Maximum inhi
This thesis concerns economic aspects of ageing and investigates incentives and outcomes related to this process. The thesis is a collection of five essays. An introductory chapter provides an overall economic perspective of ageing. Essay 1 (ch 2) examines mortality risks via duration analysis of widowed individuals in Scania, Sweden during the 19th century. The findings are qualitatively in line
Popular Abstract in Swedish Inom många olika fält hyllas dialogen. Det finns en stark och utbredd tro, främst i det västerländska samhället, att lyckas man bara upprätta en dialog kan man planera i samförstånd och lösa problem. Människor talar med varandra för att förstå, hjälpa varandra och för att skapa gemensamma värden och målsättningar. I studiet av samtal upptäcker man emellertid snabbt att In the spring of 1997 a group of parents of deaf and hearing-impaired children and representatives of a special school in the south of Sweden began to hold formally arranged meetings in order to start a “dialogue”. This particular form of collaboration became the focus of this study. The meetings lasted two to three hours and I attended seventeen of them. The transcriptions of those meetings form
