On Lactobacillus plantarum 299v, bacterial translocation and intestinal permeability.

Popular Abstract in Swedish Tarmväggen har till uppgift att både absorbera vatten och näringsämnen till kroppen, och samtidigt utgöra en barriär mot alla de bakterier, gifter och skadliga ämnen som vi får i oss. Tarmväggen innehåller också kroppens största förråd av immunologisk vävnad, dvs de celler och ämnen som utgörs kroppens försvar. I mag-tarmkanalen, ffa i tjocktarmen, finns 100 biljoner (1The gastrointestinal tract harbours a huge load of bacteria which exerts important biological functions to maintain health. In certain conditions the relation between commensal bacteria and pathogens may be set off balance, with an increase in number of pathogens and risk of bacterial translocation (BT). Disease and trauma may also render the intestinal barrier dysfunctional, inducing BT and incre

Positioning improves the oral and pharyngeal swallowing function in children with cerebral palsy

Many children with cerebral palsy have feeding difficulties. The aim of this study was to investigate if trunk and neck positioning influenced oral and pharyngeal swallow. Five children with feeding problem aged 3-10 years with cerebral palsy were examined using videofluoroscopy. All children had tetraplegia with dystonia, i.e. poor head control and poor trunk stability. All children had gross asp

The role of cytochrome b559 and tyrosineD in protection against photoinhibition during in vivo photoactivation of Photosystem II

In vivo photoactivation of Photosystem II was studied in the FUD39 mutant strain of the green alga Chlamydomonas reinhardtii which lacks the 23 kDa protein subunit involved in water oxidation. Dark grown cells, devoid of oxygen evolution, were illuminated at 0.8 μE m-2&#;s-1 light intensity which promotes optimal activation of oxygen evolution, or at 17 μE m-2&#;s-1, where photoactivation

The performance of incremental redundancy schemes based on convolutional codes in the block-fading Gaussian collision channel

The throughput performance of incremental redundancy (INR) schemes, based on short constraint length convolutional codes, is evaluated for the block-fading Gaussian collision channel. Results based on simulations and union bound computations are compared to estimates of the achievable throughput performance with random binary and Gaussian coding in the limit of large block lengths, obtained throug

Total and Gleason grade 4/5 cancer volumes are major contributors of human kallikrein 2, whereas free prostate specific antigen is largely contributed by benign gland volume in serum from patients with prostate cancer or benign prostatic biopsies

Purpose: We measured concentrations of human glandular kallikrein 2 (hK2), total prostate specific antigen (tPSA), free PSA (fPSA) and percent fPSA to evaluate their relationship to total prostate gland volume, benign prostatic hyperplasia (BPH) volume, total prostate cancer (PCa) volume (CaVol) and the volume of Gleason grades 4/5 cancer (CaVolG14) in the serum of 256 patients with PCa undergoing

Measurement of event shape variables in deep-inelastic scattering at HERA

Deep-inelastic ep scattering data taken with the H1 detector at HERA and corresponding to an integrated luminosity of 106 pb(-1) are used to study the differential distributions of event shape variables. These include thrust, jet broadening, jet mass and the C-parameter. The four-momentum transfer Q is taken to be the relevant energy scale and ranges between 14 GeV and 200 GeV. The event shape dis

Communication: An Essential Aspect of Diplomacy

Communication is generally regarded as an essential aspect of diplomacy. Proceeding from an understanding of diplomacy as a transhistorical phenomenon, this article distinguishes a number of pertinent dimensions of the communicative aspects of diplomacy and proffers examples taken from different eras and geographic regions. With a focus on continuity and change, the article analyzes the basic aspe

Species-specific alkaline phosphatase activity in freshwater spring phytoplankton: Application of a novel method

For the first time, in situ alkaline phosphatase activity (APA) was studied at the species level in a natural spring community of freshwater phytoplankton. This was achieved by utilizing a substrate called enzyme labeled fluorescence (ELF), which forms fluorescent precipitates at the site of APA. Samples collected from Lake Erken, Sweden, were assayed with ELF and a number of species belonging to

Basic Tendencies of Adjectival Accentological Development in Contemporary Russian

The present doctoral thesis is a study of the problem of "variation" in relation to word stress in Russian adjectives, in both their short and long forms. The stress variation in adjectival forms is investigated from various viewpoints, the main of which is the revelation of the basic processes of stress reorganisation in these groups of words and the establishment of main tendencies of adjectival

Biglycan isoforms with differences in polysaccharide substitution and core protein in human lung fibroblasts.

Biglycan is widely distributed in the extracellular matrix and is a member of the small proteoglycan family characterized by a core protein with leucine-rich repeat motifs. We show in this paper for the first time that biglycan from human lung fibroblasts can be expressed as different isoforms. These isoforms can be separated from the predominant form of biglycan by hydrophobic interaction chromat

Molecular and functional studies of the BCR/ABL1 fusion gene

Popular Abstract in Swedish Molekylärgenetiska och funktionella studier av BCR/ABL1 fusionsgenen: Det finns tre sorters blodkroppar, röda, vita och trombocyter, som alla bildas från gemensamma stamceller i benmärgen. När stamcellerna delar sig bildas det antingen nya stamceller eller förstadier till blodkroppar som efter ytterligare delningar blir till mogna blodkroppar. Ibland uppkommer särskildThe BCR/ABL1 fusion gene is associated with chronic myeloid leukemia and a subgroup of acute lymphoblastic leukemia. The general aim of this thesis was to increase the understanding of BCR/ABL1-induced leukemogenesis by molecular and functional studies of this fusion gene. In Article I, an experimental U937 cell line model with inducible expression of BCR/ABL1 was established and characterized. Ex

Embedded V2 in Norwegian and Swedish

Embedded declarative V2 clauses can appear in a number of different contexts in Norwegian and Swedish. What all these clauses have in common is that they have illocutionary force—they are asserted. I argue that a syntactic Force head is responsible for the illocutionary force as well as for the V2 order. Thus, the syntax and the semantics of embedded V2 clauses are closely tied together. The analy

Genetic polymorphism for glutathione-S-transferase mu in asbestos cement workers

OBJECTIVE--To investigate whether a lack of glutathione-S-transferase mu (GSTM1) activity was related to an increased risk for adverse outcome after asbestos exposure. METHODS--A study was made of 78 male former asbestos cement workers, with retrospective cohort data on exposure, radiographical findings, and lung function. Venous blood samples were obtained for the analysis of GSTM1 polymorphism b

Stem cell therapy for human neurodegenerative disorders-how to make it work

Recent progress shows that neurons suitable for transplantation can be generated from stem cells in culture, and that the adult brain produces new neurons from its own stem cells in response to injury. These findings raise hope for the development of stem cell therapies in human neurodegenerative disorders. Before clinical trials are initiated, we need to know much more about how to control stem c

Reflectionless potentials and point interactions in Pontryagin spaces

The problem of constructing generalized point interactions of the second derivative operator in L-2( R) leading to the same scattering data as for reflectionless potentials is considered. It is proved that this problem has a solution only if extensions in Pontryagin spaces are involved. The solution of the inverse scattering problem is not unique, this is illustrated by considering the scattering
