Complement evasion strategies of human pathogens - the evolutionary arms race

Although the complement system, a pivotal component of innate immunty, is centrally involved in host defense against pathogens, its overactivation or deregulation may excessively amplify inflammation and contribute to immunopathology. Periodontitis, an oral infection-driven chronic inflammatory disease, has been linked with complement disruption by periodontal bacteria, resulting in inflammation a

On the calculation of the structure of charge-stabilized colloidal dispersions using density-dependent potentials

The structure of charge-stabilized colloidal dispersions has been studied through a one-component model using a Yukawa potential with density-dependent parameters examined with integral equation theory and Monte Carlo simulations. Partial thermodynamic consistency was guaranteed by considering the osmotic pressure of the dispersion from the approximate mean-field renormalized jellium and Poisson-B

A Structure Theory of (-1,-1)-Freudenthal Kantor Triple Systems

In this paper we discuss the simplicity criteria of (-1, -1)-Freudenthal Kantor triple systems and give examples of such triple systems, from which we can construct some Lie superalgebras. We also show that we can associate a Jordan triple system to any (epsilon, delta)-Freudenthal Kantor triple system. Further, we introduce the notion of delta-structurable algebras and connect them to (-1, delta)

Retrofitting Domestic Hot Water Heaters for Solar Water Heating Systems in Single-Family Houses in a Cold Climate: A Theoretical Analysis

One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing water heaters for solar water heating systems in Swedish single-family houses was theoretically investig

Comparison of survival of patients with metastases from known versus unknown primaries: survival in metastatic cancer

Background: Cancer of unknown primary site (CUP) is considered an aggressive metastatic disease but whether the prognosis differs from metastatic cancers of known primary site is not known. Such data may give insight into the biology of CUP and the metastatic process in general. Methods: 6,745 cancer patients, with primary metastatic cancer at diagnosis, were identified from the Swedish Cancer Reg

Multiplicity dependence of pion, kaon, proton and lambda production in p-Pb collisions at root s(NN)=5.02 TeV

In this Letter, comprehensive results on pi(+/-), K-+/-, K-S(0), p((p) over bar) and A((A) over bar) production at mid-rapidity (0 < y(CMS) < 0.5) in p-Pb collisions at root s(NN) = 5.02 TeV, measured by the ALICE detector at the LHC, are reported. The transverse momentum distributions exhibit a hardening as a function of event multiplicity, which is stronger for heavier particles. This behavior i

Incident urothelial cancer in the Malmö Diet and Cancer Study: cohort characteristics and further validation of ezrin as a prognostic biomarker.

Reduced membranous expression of the cytoskeleton-associated protein ezrin has previously been demonstrated to correlate with poor prognosis in urothelial bladder cancer in several independent studies. The present study provides a first description of clinicopathological characteristics of incident urothelial cancers, not only located to the bladder, in the prospective, population-based cohort stu

Breakthrough in cardiac arrest: reports from the 4th Paris International Conference.

Jean-Luc Diehl The French Intensive Care Society organized on 5th and 6th June 2014 its 4th "Paris International Conference in Intensive Care", whose principle is to bring together the best international experts on a hot topic in critical care medicine. The 2014 theme was "Breakthrough in cardiac arrest", with many high-quality updates on epidemiology, public health data, pre-hospital and in-ICU c

Changes in human placental oxygenation during maternal hyperoxia estimated by blood oxygen level-dependent magnetic resonance imaging (BOLD MRI)

Objectives To investigate changes in human placental oxygenation during maternal hyperoxia using non-invasive blood oxygen level-dependent (BOLD) magnetic resonance imaging (MRI). Methods Eight healthy pregnant women with uncomplicated singleton pregnancies at gestational weeks 28-36 were examined with BOLD MRI, over two consecutive 5-min periods of different oxygenation: first normoxia (21% O-2)

Design of innovation policy through diagnostic analysis: identification of systemic problems (or failures)

"Activities" in innovation systems are the determinants of the development and diffusion of innovations. Examples are R&D, provision of organizations and institutions, financing of innovations, incubation, etc. These activities are partly performed by private organizations and partly by public organizations, the latter performing tasks that constitute innovation policy. As a basis for innovati

Effect of nonrelativistic interface Hamiltonian on optical transitions in broken-gap heterostructures

Using the Burt-Foreman envelope function theory and an eight-band k.p model, we have extended our previous work [Semenikhin et al. Phys. Rev. B 76, 035335 (2007)] on optical transitions in InAs/GaSb quantum wells grown along the [001] direction by completing the interface Hamiltonian with the inclusion of its nonrelativistic part. We found a substantial contribution of the nonrelativistic term to

Stacking of adjacent graphene layers grown on C-face SiC

Graphene was grown on the C-face of nominally on-axis SiC substrates using high-temperature sublimation with Ar as the buffer inert gas. The results of studies of the morphology, thickness, and electronic structure of these samples using low-energy electronmicroscopy (LEEM), x-ray photoelectron emission microscopy, photoelectron spectroscopy, angle-resolved photoelectron spectroscopy (ARPES), and

The genomic landscape of hypodiploid acute lymphoblastic leukemia

The genetic basis of hypodiploid acute lymphoblastic leukemia (ALL), a subtype of ALL characterized by aneuploidy and poor outcome, is unknown. Genomic profiling of 124 hypodiploid ALL cases, including whole-genome and exome sequencing of 40 cases, identified two subtypes that differ in the severity of aneuploidy, transcriptional profiles and submicroscopic genetic alterations. Near-haploid ALL wi

Synthesis and self-aggregation of enantiopure and racemic molecular tweezers based on the bicyclo[3.3.1]nonane framework.

A pair of molecular tweezers (syn-4) that consists of quinoline and pyrazine units fused to a bicyclic framework is presented. The tweezers were synthesised both as a racemic mixture (rac-4) and an enantiomerically pure form ((R,R,R,R)-4) starting from either racemic or enantiomerically pure bicyclo[3.3.1]nonane-2,6-dione (3). Homochiral dimers were observed in the solid state for rac-4. The self-

Effect of experimental complex III deficiency on respiratory chain assembly and function

Popular Abstract in Swedish Kroppens förmåga att omvandla matens energi till energi som kan användas i organen sker i små organeller som finns i alla kroppens celler, mitokondrierna. Avvikelser i mitokondrierna förorsakar därför ofta svåra sjukdomar. GRACILE syndrom är en medfödd mitokondriell sjukdom, som leder till svår tillväxthämning, problem med ämnesomsättningen och tidig död. Det finns ingeThe assembly of respiratory chain complexes in the mitochondrial inner membrane requires specific factors. Once assembled to form a mature functional complex, complex III (CIII) is a dimer consisting of two monomers, each with eleven subunits. To date, seven assembly factors for CIII are known, of which BCS1L incorporates the Rieske iron-sulfur protein (RISP) in the last stage of the assembly. The
