A novel multi-strain probiotic and synbiotic supplement for prevention of Clostridium difficile infection in a murine model.

The protective effect of a multi-strain probiotic and synbiotic formulation was evaluated in C57BL/6 mice infected with Clostridium difficile (CD) NAP1/027. Antibiotic treated mice were divided into four groups. Group 1, fed with a synbiotic formulation consisting of Lactobacillus plantarum F44, L. paracasei F8, Bifidobacterium breve 46, B. lactis 8:8, galacto-oligosaccharides (GOS), isomalto-olig

Studies of protein A and herpes simplex virus-1 induced Fc gamma-binding specificities. Different binding patterns for IgG3 from Caucasian and Oriental subjects

Herpes simplex virus type 1 (HSV-1) expresses a receptor that binds the Fc portion of IgG. This HSV-1 Fc gamma-binding protein is, like protein A of Staphylococcus aureus, known to bind human IgG1, IgG2 and IgG4 but not IgG3 subclasses. However, IgG3 with the allotype Gm(s+)(t+), prominent in the Oriental population, reacts with protein A. This prompted us to investigate the reactivity of Oriental

Catalytic Cycle of Multicopper Oxidases Studied by Combined Quantum- and Molecular-Mechanical Free-Energy Perturbation Methods.

We have used combined quantum mechanical and molecular mechanical free-energy perturbation methods in combination with explicit solvent simulations to study the reaction mechanism of the multicopper oxidases, in particular, the regeneration of the reduced state from the native intermediate. For 52 putative states of the trinuclear copper cluster, differing in the oxidation states of the copper ion

Mutational tuning of galectin-3 specificity and biological function.

Galectins are defined by a conserved beta-galactoside binding site, which has been linked to many of their important functions in e.g. cell adhesion, signaling and intracellular trafficking. Weak adjacent sites may enhance or decrease affinity for natural beta-galactoside containing glycoconjugates, but little is known about the biological role of this modulation of affinity (fine specificity). We

Characterization of probe contact effects on diffuse reflectance spectroscopy measurements

Diffuse reflectance spectroscopy (DRS) is a rapid, non-invasive optical method widely adopted to gain diagnostic information of tissue. The most flexible approach to this method is a fiber-optic contact-probe used with a spectroscopy system. A challenge of this method is that the external pressure brought by the probe can significantly affect the tissue optical properties as well as the light coup

Vowel spaces in Swedish adolescents with cochlear implants

Abstract in UndeterminedThis paper examines vowel production in Swedish adolescents with cochlear implants. Twelve adolescents with cochlear implants and 11 adolescents with normal hearing participated. Measurements were made of the first and second formants in all the nine long Swedish vowels. The values in hertz were bark-transformed, and two measures of the size of the vowel space were obtained

Label-free protein quantification in freshly ejaculated versus post-mating spermatophores of the noble crayfish Astacus astacus.

Crayfish spermatophores are deposited on the body surface of the female during mating and remain there for a period of time before fertilization ensues. Post-mating changes in protein expression level in the noble crayfish Astacus astacus spermatophore were quantified. In-gel digestion and high resolution mass spectrometry were used for label-free protein quantification. One hundred twelve protein

The Limits of Mindreading

Contemporary cognitive psychology is dominated by an individualistic and mentalistic approach to the mind. This Cartesian heritage is evident in studies of social understanding, that is, how we understand others. It is argued that this approach and metaphors like reading minds have failed, and should be replaced with a discursive approach, where public and shared socio-linguistic intenand normativ

Purpose – The rate of turnover of hospital managers has been high in Sweden. Hospitals are regarded to be difficult to manage, which is connected with different discourses and action logics such as politics, medicine, care and management creating complex conditions for hospital management. The purpose of this paper is to analyse hospital managers' management conditions in conjunction with hospital

Mixed Micelles of a PEO-PPO-PEO Triblock Copolymer (P123) and a Nonionic Surfactant (C12EO6) in Water. A Dynamic and Static Light Scattering Study

The present article reports on static and dynamic light scattering (SLS and DLS) studies of aqueous solutions of the nonionic surfactant C12EO6 and the poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) triblock copolymer EO20PO68EO20 (P123) at temperatures between 25 and 45 degrees C. In water, P123 self-assembles into spherical micelles with a hydrodynamic radius of 10 nm, and at 40

An Architecture for Resource Bounded Agents

We study agents situated in partially observable environments, who do not have sufficient resources to create conformant (complete) plans. Instead, they create plans which are conditional and partial, execute or simulate them, and learn from experience to evaluate their quality. Our agents employ an incomplete symbolic deduction system based on Active Logic and Situation Calculus for reasoning abo

Statistical modelling of spike libraries for simulation of extracellular recordings in the cerebellum

Brain machine interfaces with chronically implanted microelectrode arrays for signal acquisition require algorithms for successful detection and classification of neural spikes. During the design of such algorithms, signals with a priori known characteristics need to be present. A common way to establish such signals is to model the recording environment, simulate the recordings and store ground t

Use of Serum or Buffer-Changed EDTA-Plasma in a Rapid, Inexpensive, and Easy-To-Perform Hemolytic Complement Assay for Differential Diagnosis of Systemic Lupus Erythematosus and Monitoring of Patients with the Disease

We previously described a simplified quantitative hemolytic assay for classical pathway (CP) hemolytic function in serum that has been shown to correlate with the 50% hemolytic complement (CH50) assay. In the present study, we used this assay to compare CP functions; plasma levels of C3, C4, and C3dg; and ratios of C3dg to C3 in healthy individuals and patients with systemic lupus erythematosus (S

Small angle neutron scattering study of lysozyme-sodium dodecyl sulfate aggregates

The lysozyme-sodium dodecyl sulfate-water system features several interesting aggregation phenomena and is also of interest as it constitutes a model system for mixtures of a charged colloid with an oppositely charged surfactant, as both colloid and surfactant are pure and monodisperse compounds. The structure of such mixed protein - surfactant systems has been investigated by means of SANS contra
