Shiga toxin pathogenesis : kidney complications and renal failure
The kidneys are the major organs affected in diarrhea-associated hemolytic uremic syndrome (D(+)HUS). The pathophysiology of renal disease in D(+)HUS is largely the result of the interaction between bacterial virulence factors such as Shiga toxin and lipopolysaccharide and host cells in the kidney and in the blood circulation. This chapter describes in detail the current knowledge of how these bac
Clouding of nonionic surfactants
Nonionic surfactants have broad applications such as cleaning and dispersion stabilization, which frequently are hampered by strong temperature sensitivities. As manifested by clouding and decreased solubility with increasing temperature, the interaction between water and the oligo(oxyethylene) head-groups is becoming less favorable. Different aspects of surfactant self-assembly, like the critical
Cytokine repertoire of epithelial cells lining the human urinary tract
PURPOSE: To examine the cytokine profile of epithelial cells lining the human urinary tract with the aim of differentiating between the constitutive and disease-related cytokine production in these tissues.MATERIALS AND METHODS: Sections from the renal pelvis, ureter, bladder or urethra were obtained from 22 patients undergoing urinary tract surgery and were stained with monoclonal antibodies to i
von Willebrand factor mediates increased platelet retention in recurrent thrombotic thrombocytopenic purpura
The plasma cryoprecipitate of two brothers with recurrent thrombotic thrombocytopenic purpura (TTP) was previously found to mediate increased platelet retention and contain ultra-large von Willebrand factor (vWF) multimers during remissions. We conducted this study to examine if vWF is involved in the increased platelet retention in TTP. Platelet retention decreased when the patients' plasma was i
Bernard-Soulier syndrome Karlstad : Trp 498-->Stop mutation resulting in a truncated glycoprotein Ib alpha that contains part of the transmembranous domain
In Bernard-Soulier syndrome, a hereditary bleeding disorder, the platelets are deficient in the glycoprotein (GP) Ib-IX-V complex, a major receptor for the von Willebrand factor. The components of the complex are encoded by separate genes. Patients with this syndrome have a variable expression level of the receptor protein on platelets depending on the specific genetic abnormality. We describe a p
The role of lipopolysaccharide and Shiga-like toxin in a mouse model of Escherichia coli O157:H7 infection
The role of lipopolysaccharide (LPS) and Shiga-like toxin (SLT) in the pathogenesis of hemolytic uremic syndrome (HUS) was studied in a mouse model. Mice inoculated intragastrically with Escherichia coli O157:H7 developed gastrointestinal, neurologic, and systemic symptoms, necrotic foci in the colon, glomerular and tubular histopathology, and fragmented erythrocytes. LPS-responder (C3H/HeN) mice
Composers on Stage : Ambiguous authorship in contemporary music performance
In recent years, workflows within the field of contemporary classical music have changed drastically. Increasingly, composers are active in the process of creating and co-creating performances, not only the auditory dimensions but also the visual design and theatrical staging. The practice has recently been termed The New Discipline (Walshe, 2016). Of particular interest to the present article are
The Human Diabetes Proteome Project (HDPP) : The 2014 update
Diabetes is an increasing worldwide problem leading to major associated health issues and increased health care costs. In 2012, 9.3% of the American population was affected by diabetes, according to the American Diabetes Association, with 1.7 million of new cases since during the year (www.diabetes.org). Proteome initiatives can provide a deeper understanding of the biology of this disease and hel

Instantaneous 3D imaging of flame species using coded laser illumination
Three-dimensional (3D) imaging of dynamic objects that rapidly undergoes structural changes, such as turbulent combusting flows, has been a long-standing challenge, mainly due to the common need for sequential image acquisitions. To accurately sense the 3D shape of the sample, all acquisitions need to be recorded within a sufficiently short time-scale during which the sample appears stationary. He

K-Cl-S chemistry in air and oxy-combustion atmospheres
This paper studies the consequences on high temperature corrosion when biomass is co-fired with coal in oxy-fuel combustion, a concept that would enable negative CO2 emissions by combining renewable fuels with CO2 capture. The particular focus of the work is the sulphation of alkali chlorides which is studied by means of experiments and modelling. The melting point of alkali sulphates is higher th
Investigations of microwave stimulation of a turbulent low-swirl flame
Irradiating a flame by microwave radiation is one of several plasma-assisted combustion (PAC) technologies that can be used to modify the combustion chemical kinetics in order to improve flame-stability and to delay lean blow-out. One practical implication is that engines may be able to operate with leaner fuel mixtures and have an improved fuel flexibility capability including biofuels. In additi
Strategy for single-shot CH3 imaging in premixed methane/air flames using photofragmentation laser-induced fluorescence
Single-shot imaging of methyl radical (CH3) in premixed methane/air flames is demonstrated using photofragmentation laser-induced fluorescence (PF-LIF) technique. A pump-probe strategy was adopted with the pump laser at 212.8 nm photolyzing CH3, and with the probe laser at 426.8 nm detecting the photolyzed CH (X 2Π) fragments. Spatially resolved spectrograph of the PF-LIF signal from a stable lami

Characterization of the reaction zone structures in a laboratory combustor using optical diagnostics : From flame to flameless combustion
Flame emission spectra and OH* imaging are carried out together with planar laser-induced fluorescence (PLIF) of OH and CH2O to characterize the reaction zone structures of three combustion modes, i.e. a flame mode, a transition mode and a flameless mode, established in a laboratory combustor. Spectroscopic measurements indicate that the invisibility of the flameless mode can be attributed to a mo

Ethane thermometry using rotational coherent anti-Stokes Raman scattering (CARS)
The complete rotational CARS (coherent anti-Stokes Raman scattering) spectrum of ethane (C2H6) has for the first time been recorded instantaneously under high spectral resolution, and the potential for thermometry has been investigated. Experiments were performed in the temperature range 292-650K in pure ethane and in binary mixtures with nitrogen. A polarization technique was used to suppress the
A comparison between direct numerical simulation and experiment of the turbulent burning velocity-related statistics in a turbulent methane-air premixed jet flame at high Karlovitz number
A three-dimensional (3D) direct numerical simulation (DNS) of an experimental turbulent premixed jet flame at high Karlovitz number was studied. The DNS resolution adequately resolves both the flame and turbulence structures. A reduced chemical mechanism for premixed CH4/air flames with NOx based on GRI-Mech3.0 was used, including 268 elementary reactions, and 28 transported species. Consistent po
