Mycobacteria-infected bystander macrophages trigger maturation of dendritic cells and enhance their ability to mediate HIV transinfection

Synergistic interplay between Mycobacterium tuberculosis (Mtb) and HIV in coinfected ind-ividuals leads to the acceleration of both tuberculosis and HIVdisease. Mtb, as well as HIV, may modulate the function of many immune cells, including DCs. To dissect the bystander impact of Mfs infected with Mtb on DC functionality, we here investigated changes in DC phenotype, cytokine profiles, and HIV-1 tr

Comparative Analysis of the Humoral Immune Response to Moraxella catarrhalis and Streptococcus pneumoniae Surface Antigens in Children Suffering from Recurrent Acute Otitis Media and Chronic Otitis Media with Effusion

A prospective clinical cohort study was established to investigate the humoral immune response in middle ear fluids (MEF) and serum against bacterial surface proteins in children suffering from recurrent acute otitis media (rAOM) and chronic otitis media with effusion (COME), using Luminex xMAP technology. The association between the humoral immune response and the presence of Moraxella catarrhali

A separation principle for distributed control

A linear quadratic control problem is considered, where several different controllers act as a team, but with access to different measurements. The state feedback solution obtained in a previous paper is here extended to output feedback and a separation principle is proved. The condition that certain measurements are unavailable to some state estimators is enforced by imposing a requirement that t

Detection and Classification of Liquid Explosives using NMR

In this work, we present a novel method for non-invasive identification of liquids, for instance to allow for the detection of liquid explosives at airports or border controls. The approach is based on a nuclear magnetic resonance technique with an inhomogeneous magnetic field, forming estimates of the liquid's spin-spin relaxation time, T2, and diffusion constant, D, thereby allowing for a unique

What Do You Like? Early Design Explorations of Sound and Haptic Preferences

This study is done within the framework of a project aimed at developing a wearable device (a bracelet) intended to support sensory motor rehabilitation of children with visual impairments. We present an exploratory study of aesthetic/hedonistic preferences for sounds and touch experiences among visually impaired children. The work is done in a participatory setting, and we have used mixed methods

Background and Foreground Modeling Using an Online EM Algorithm

A novel approach to background/foreground segmentation using an online EM algorithm is presented. The method models each layer as a Gaussian mixture, with local, per pixel, parameters for the background layer and global parameters for the foreground layer, utilising information from the entire scene when estimating the foreground. Additionally, the online EM algorithm uses a progressive learning r

Main-sequence progenitor configurations of the NN Ser candidate circumbinary planetary system are dynamically unstable

Recent observations of the NN Serpentis post-common envelope binary system have revealed eclipse timing variations that have been attributed to the presence of two Jovian-mass exo-planets. Under the assumption that these planets are real and survived from the binary's main-sequence state, we reconstruct initial binaries that give rise to the present NN Ser configuration and test the dynamical stab

Molecular engineering of a thermostable carbohydrate-binding module

Structure-function studies are frequently practiced on the very diverse group of natural carbohydrate-binding modules in order to understand the target recognition of these proteins. We have taken a step further in the study of carbohydrate-binding modules and created variants with novel binding properties by molecular engineering of one such molecule of known 3D-structure. A combinatorial library

Helicobacter pylori lipopolysaccharide in the IL-2 milieu activates lymphocytes from dyspeptic children

In this study, we assessed the proliferative response of peripheral blood mononuclear leukocytes (PBML) from 33 children/young adolescents with chronic dyspepsia, to H. pylori LPS in the presence and absence of IL-2 as a T cell growth factor. A rapid urease test (RUT) and a presence of Helicobacter-like organisms (HLO) in the biopsy specimens allowed us to distinguish RUT/HLO-positive (17/33) and

Longitudinal epitope analysis of insulin-binding antibodies in type 1 diabetes

Autoantibodies to insulin (IAA) are one of the first markers of the autoimmune process leading to type 1 diabetes (T1D). While other autoantibodies in T1D have been studied extensively, relatively little is known about IAA and their binding specificities, especially after insulin treatment is initiated. We hypothesize that insulin antibodies (IA) that develop upon initiation of insulin treatment d

Non-invasive measurement of arterial longitudinal movement

In arterial vessel wall characterisation the longitudinal movements of vessels have gained little or no attention. It has been presumed that the arterial vessels move very little in the longitudinal direction. With modern high resolution ultrasound it can, however, be seen that arterial vessels move not only in the circumferential, but also in longitudinal direction. This paper describes a non-inv

Potential barrier effects in Cs 3d resonance photoemission of CsF

We present and discuss the Cs 3d X-ray absorption spectra and resonant photoelectron emission spectra of CsF. The resonant photoelectron spectra excited at the Cs 3d absorption maxima, exhibit a strong resonance behavior. The different behaviour of participator and spectator channels and interference effects of the 4d partial photoionisation cross-section at the 3d resonances are discussed. The ex

AXIN1 in Plasma or Serum Is a Potential New Biomarker for Endometriosis

Although endometriosis is considered an inflammatory disease, no reliable diagnostic biomarkers exist for use in clinical practice. The aim was to investigate the inflammatory profile in endometriosis using an exploratory approach of inflammation-related proteins. Patients with laparoscopy-verified endometriosis (N = 172), women with microscopic colitis (N = 50), healthy controls (N = 31), and age

Extravascular lung water index: Diagnostic accuracy and relation to lung injury and mortality in patients with shock

INTRODUCTION. The diagnosis of acute lung injury may be more robust if more accurate physiological markers can be identified. Extravascular lung water index (EVLWI) may be useful and has been shown to correlate with respiratory function and mortality in patients with sepsis and ARDS. Whether this applies to a wider population, and which index performs best, are unclear. OBJECTIVES. We hypothesized

Integrating renewable energy technologies into distributed energy systems maintaining system flexibility

Flexibility of the energy system plays a vital role when integrating non-dispatchable renewable energy technologies. However, flexibility of the energy system has been often discussed only focusing on the operation of the energy system. This study extends the flexibility concept considering both design and operation of the energy system. In order to achieve this, pseudo chronological scenarios use

Mucin staining is of limited value in addition to basic immunohistochemical analyses in the diagnostics of non-small cell lung cancer

Accurate diagnosis of histological type is important for therapy selection in lung cancer. Immunohistochemical (IHC) and histochemical stains are often used to complement morphology for definite diagnosis and are incorporated in the WHO classification. Our main aim was to compare different mucin stains and assess their value in relation to common IHC analyses in lung cancer diagnostics. Using tiss

Dietary factors influence the recovery rates of Helicobacter pylori in a BALB/cA mouse model

The aim of this study was to assess the ability of different mouse diets to sustain an H. pylori infection in BALB/cA mice. Four commercially available mouse diets were compared. Experiment 1: Mice were fed the four diets for seven days before infection, infected three times at two-day intervals with 0.1 ml of 10(9) colony-forming units/ml H. pylori cells. H. pylori strains (n = 4) were cultured o
