Superantigens are toxins produced by Staphylococcus aureus, called staphylococcal enterotoxins (abbreviated SEA to SEU). They can cross-link the T cell receptor (TCR) and major histocompatibility complex class II, triggering a massive T cell activation and hence disease. Due to high stability and toxicity, superantigens are potential agents of bioterrorism. Hence, antagonists may not only be usefu
Diiron complexes bearing redox active diamine ligands have been studied as models of the active site of [FeFe]-hydrogenases. Heating [Fe2(CO)6(μ-edt)] (edt = 1,2-ethanedithiolate) with 2,2′-bipyridine (2,2′-bipy) or 1,10-phenanthroline (1,10-phen) in MeCN in the presence of Me3NO leads to the formation of [Fe2(CO)4(κ2-2,2′-bipy)(μ-edt)] (1-edt) and [Fe2(CO)4(κ2-1,10-phen)(μ-edt)] (2-edt), respecti
Patients and methods A comprehensive literature search was conducted. We measured pooled rate of lesion visualization improvement and improvement in lesion detection comparing FICE settings 1 – 3 and WLE, for angioectasias and ulcers/erosions. Pooled results were derived using the random-effects model because of high heterogeneity as measured by I 2. Repeated-measures analysis of variance (ANOVA)
Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by insulin deficiency and resultant hyperglycemia. Complex interactions of genetic and environmental factors trigger the onset of autoimmune mechanisms responsible for development of autoimmunity to β cell antigens and subsequent development of T1D. A potential role of virus infections has long been hypothesized, and growing evide
The interaction of bacterial pathogens with their hosts' innate immune systems can be extremely complex and is often difficult to disentangle experimentally. Using mouse models of bacterial infections, several laboratories have successfully applied genetic approaches to identify novel host genes required for innate immune defense. In addition, a variety of creative bacterial genetic schemes have b
Avoiding absorption in the upper gastrointestinal tract is one of the challengesconsidering targeted colon delivery but not much attention has been paid tomicrobial activity of vector material in saliva and small intestine. The aim of thepresent study was to develop an in vitro prototype model for evaluatingdigestion of encapsulation material by oral bacterial species based on readilyobtainable sa
Aims: We applied near-infrared-spectroscopy (NIRS) to measure absolute frontal cerebral tissue oxygen saturation (SctO2) during head-up tilt test (HUT) in patients investigated for unexplained syncope.Methods and results: Synchronized non-invasive beat-to-beat haemodynamic monitoring, ECG, SctO2 (NIRS; normal range: 60-80%), and peripheral oxygen saturation (left hand, SpO2) were applied during HU
A Good Practice is a practice that works well, produces good results, and is recommended as a model. MACVIA-ARIA Sentinel Network (MASK), the new Allergic Rhinitis and its Impact on Asthma (ARIA) initiative, is an example of a Good Practice focusing on the implementation of multi-sectoral care pathways using emerging technologies with real life data in rhinitis and asthma multi-morbidity. The Euro
Modified ultrafiltration (MUF) is often used in conjunction with paediatric cardiac surgery with cardiopulmonary bypass (CPB) and is thought to improve clinical outcome. It is unclear whether these improvements (if any) are due to the removal of inflammatory mediators. In this prospective study, 18 children aged 12-24 months undergoing uncomplicated cardiac surgery with methylprednisolone added in
Natural radiative lifetimes have been measured in the odd-parity Rydberg series 6pns (n=7-13) and 6pnd (n=6-13) of neutral lead using time-resolved UV laser-induced fluorescence from a laser-produced plasma. A relativistic Hartree-Fock calculation taking configuration interaction into account in a detailed way has also been performed for odd-as well as even-parity states for testing the ability of
Endothelial cells express both estrogen receptor (ER) alpha and beta. The objective of this study was to investigate if and how mediators of inflammation regulate endothelial cell ERalpha and ERbeta expression. ERalpha and ERbeta transcript and protein expression were determined by real-time quantitative PCR and Western blotting, respectively, in endothelial cell line bEnd.3 cells stimulated with
OBJECTIVES: We investigated whether menopausal vasomotor symptoms (VMS) are related to an adverse cardiovascular risk profile. Furthermore, we examined the association between estradiol levels and VMS, and whether an association between VMS and cardiovascular risk factors can be explained by estradiol levels. STUDY DESIGN: We used data from a Swedish population-based sample of 5857 women, aged 50-
Natural radiative lifetimes of 10 levels of singly ionized ytterbium have been measured with time-resolved laser spectroscopy. Free Yb+ ions were produced in a laser-induced plasma. A stimulated Brillouin scattering technique has been used to produce laser pulses as short as 1 ns for the excitation of short-lived Yb+ states. Pseudo-relativistic Hartree-Fock calculations, taking into account the co
OBJECTIVE: To investigate to what extent individuals participated in guideline-based first-line treatments before being assigned to a wait list for knee replacement for osteoarthritis (OA), and to what extent they were recommended such treatments once on the list. Factors associated with participation in first-line management were also investigated.DESIGN: All patients on the waiting list ≥ three
Epidemiological studies have shown an inverse relation between a whole grain consumption and risk of type-2 diabetes and cardiovascular disease. One tentative mechanism relates to colonic metabolism of indigestible carbohydrates. In a previous study, we reported a positive relation between colonic fermentation and improved glucose tolerance. This work can be seen as an extension of that study, foc
We study how the orientational correlations of DNA confined to nanochannels depend on the channel diameter D by means of Monte Carlo simulations and a mean-field theory. This theory describes DNA conformations in the experimentally relevant regime where the Flory-de Gennes theory does not apply. We show how local correlations determine the dependence of the end-to-end distance of the DNA molecule
