P>Studies have shown that familial risk contributes to aetiology of lymphomas. Using large population registries from Sweden, we evaluated risk of lymphoma subtypes among first-degree relatives of 2668 follicular lymphoma (FL) patients, 2517 diffuse large B-cell lymphoma (DLBCL) patients, and 6963 Hodgkin lymphoma (HL) patients compared to first-degree relatives of controls. Relatives were at the
Background: The importance of early life conditions and current conditions for mortality in later life was assessed using historical data from four rural parishes in southern Sweden. Both demographic and economic data are valid. Methods: Longitudinal demographic and socioeconomic data for individuals and household socioeconomic data from parish registers were combined with local area data on food
If u is a sufficiently smooth maximal plurisubharmonic function such that the complex Hessian of u has constant rank, it is known that there exists a foliation by complex manifolds, such that u is harmonic along the leaves of the foliation. In this paper, we show a partial analogue of this result for maximal plurisubharmonic functions that are merely continuous, without the assumption on the compl
In this prospective study, mortality, rehabilitation, and new amputations on the same or on the contralateral leg were studied in 189 patients with diabetes who had achieved healing of an index amputation. Ninety-three patients had achieved healing after an index minor (below the ankle) and 96 after an index major (above the ankle) amputation, precipitated by a foot ulcer. The healing time was 29
Shikimic acid, which is produced in the aromatic amino acid pathway in plants and microorganisms, is an industrially interesting chiral starting material for the synthesis of many chemical substances, e.g. the influenza medicine Tamiflu (R). When produced by genetically modified Escherichia coli it has previously been found that carbon-rich conditions (e.g. phosphate-limitation) favors production
The UV photodissociation (<5 eV) of diiodomethane (CH(2)l(2)) is investigated by spin-orbit ab inito calculations. The experimentally observed photodissociation channels in the gas and condensed phases are clearly assigned by multi-state second-order multiconfigurational perturbation theory in conjunction with spin-orbit interaction through complete active space-state interaction potential energy
BACKGROUND: Representing is about theories and theory formation. Philosophy of science has a long-standing interest in representing. At least since Ian Hacking's modern classic Representing and Intervening (1983) analytical philosophers have struggled to combine that interest with a study of the roles of intervention studies. With few exceptions this focus of philosophy of science has been on phys
We investigate the possibility to use coated metallic nanoparticles for single-molecule surface-enhanced spectroscopy by extending the Mie theory. The aggregates of metallodielectric spheres of Au and Ag show a strong local intensity enhancement in the cavity between particles, which can result in up to a 10(14)-fold increase for surface-enhanced Raman scattering. We also examine the thickness of
The European procedural guidelines for radionuclide imaging of myocardial perfusion and viability are presented in 13 sections covering patient information, radiopharmaceuticals, injected activities and dosimetry, stress tests, imaging protocols and acquisition, quality control and reconstruction methods, gated studies and attenuation-scatter compensation, data analysis, reports and image display,
Background: Soft-tissue injuries of the wrist are often not recognized in patients with distal radial fractures, yet scapholunate injuries have been reported to occur in association with as many as 54% of distal radial fractures. The true prevalence and natural history of intercarpal ligament injury are not known. Methods: This prospective observational study assessed the prevalence and one-year o
Severe alpha1-antitrypsin (AAT) deficiency predisposes to emphysema development. Highly variable rates of decline in lung function are reported in PiZZ individuals. The annual decline in forced expiratory volume in one second (FEV1; delta FEV1) was analysed in relation to smoking status in a cohort of 608 adult PiZZ individuals included in the Swedish national AAT deficiency register. Delta FEV1 w
BACKGROUND: Extracorporeal immunoadsorption (ECAT) is a method of reducing activity in radiosensitive organs by removing excess monoclonal antibodies (MAbs) from the blood. Previously, the authors experimentally evaluated ECAT based on the avidin-biotin concept after intravenous administration of radioimmunoconjugates. The aim of the current study was to determine whether ECAT could be used to red
The increasing availability of human pluripotent stem cells provides new prospects for neural-replacement strategies and disease-related basic research. With almost unlimited potential for self-renewal, the use of human embryonic stem cells (ESCs) bypasses the restricted supply and expandability of primary cells that has been a major bottleneck in previous neural transplantation approaches. Transl
Mammals have four deoxyribonucleoside kinases, the cytoplasmic (TK1) and mitochondrial (TK2) thymidine kinases, and the deoxycytidine (dCK) and deoxyguanosine (dGK) kinases, which salvage the precursors for nucleic acids synthesis. In addition to the native deoxyribonucleoside substrates, the kinases can phosphorylate and thereby activate a variety of anti-cancer and antiviral prodrugs. Recently,
Tendon injuries at the epicondyle can occur in athletes and workers whose job functions involve repetitive, high force hand activities, but the early pathophysiologic changes of tendon are not well known. The purpose of this study was to evaluate early tendon structural changes, specifically the formation of microtears, caused by cyclical loading. The Flexor Digitorum Profundus (FDP) muscle of nin
Protein S expresses cofactor activity for activated protein C (APC) by enhancing the APC-catalyzed proteolysis at R-306 in factor Va. It is generally accepted that only free protein S is active and that complex formation with C4b-binding protein (C4BP) inhibits the APC-cofactor activity of protein S. However, the present study shows that protein S-C4BP expresses APC-cofactor activity and stimulate
Fatigue damage due to a special class of non-Gaussian broadband loadings is considered. Specifically, the loadings are considered to be non-monotonic transformation of stationary, Gaussian random processes. A linear damage accumulation rule is assumed and the rain-flow cycle counting method is considered. Analytical expressions are developed for estimating the expected rain-flow fatigue damage. Ea
Bose-Einstein correlations of charged kaons are used to probe Au+Au collisions at s(NN)=200 GeV and are compared to charged pion probes, which have a larger hadronic scattering cross section. Three-dimensional Gaussian source radii are extracted, along with a one-dimensional kaon emission source function. The centrality dependences of the three Gaussian radii are well described by a single linear
OBJECTIVE: To investigate changes in regional blood flows (RBF) and vascular porosity during the early phase of the autologous collagen II induced arthritis model (CIA) in rats and the possible influence of indomethacin and nitric oxide (NO) synthase on these variables. METHODS: RBF was measured with the microsphere method and vascular porosity by determination of extravasation of radiolabeled alb
