Regulation of the polarity kinases PAR-1/MARK by 14-3-3 interaction and phosphorylation

Members of the PAR-1/MARK kinase family play critical roles in polarity and cell cycle control and are regulated by 14-3-3 scaffolding proteins, as well as the LKB1 tumour suppressor kinase and atypical protein kinase C (PKC). In this study, we initially investigated the mechanism underlying the interaction of mammalian MARK3 with 14-3-3. We demonstrate that 14-3-3 binding to MARK3 is dependent on

Strategy for surveying the proteome using affinity proteomics and mass spectrometry.

Antibody-based microarrays is a rapidly evolving technology that has gone from the first proof-of-concept studies to more demanding proteome profiling applications, during the last years. Miniaturized microarrays can be printed with large number of antibodies harbouring predetermined specificities, capable of targeting high- as well as low-abundant analytes in complex, nonfractionated proteomes. C

The COST benchmark simulation model - current state and future perspective

The paper introduces the philosophy and current status of a benchmark for the evaluation of control strategies in wastewater treatment plants and also the forthcoming developments and future perspectives. The work has been carried out within the framework of two COST Actions (682 and 624) and in close collaboration with the IWA Task Group on Respirometry. The benchmark is a platform-independent si

Low glycaemic index (GI) foods improve glucose control in children with type I diabetes.

Aim: Does metabolic control improve in children with insulin dependent diabetes mellitus (IDDM), when modifying the quality of carbohydrates by introducing low glycaemic index (GI) foods? Methods: The inclusion criteria for the study was children with diabetes mellitus type 1, age from 7 to 11 years old, they should have a moderate glucose control with HbA1c between 7,5 to 8,5 and no allergy to ce

Increased sensitivity to ADP-aggregation in aspirin treated patients with recurrent ischemic stroke?

AIM: Antiplatelet therapy in order to reduce the platelet aggregability is widely used to prevent recurrent stroke events. Data from several studies indicates that the inter-individual variation concerning the ability of standard doses of aspirin to inhibit platelet aggregation is substantial. The rationale of the present study was to test whether platelet aggregation in whole blood was enhanced i

Psoriasin, one of several new proteins identified in nasal lavage fluid from allergic and non-allergic individuals using 2-dimensional gel electrophoresis and mass spectrometry

Background: Extravasation and luminal entry of plasma occurs continuously in the nose. This process is markedly facilitated in patients with symptomatic allergic rhinitis, resulting in an increased secretion of proteins. Identification of these proteins is an important step in the understanding of the pathological mechanisms in allergic diseases. DNA microarrays have recently made it possible to c

Using cluster analysis to examine dietary patterns: nutrient intakes, gender, and weight status differ across food pattern clusters

OBJECTIVE: This study explored the usefulness of cluster analysis in identifying food choice patterns of three groups of adults in relation to their energy intake. DESIGN: Food frequency data were converted to percentage of total energy from 38 food groups and entered into a cluster analysis procedure. Subjects in the emerging food group patterns were compared in terms of weight status, demographi

Development and characterisation of a recombinant Saccharomyces cerevisiae mutant strain with enhanced xylose fermentation properties

The purpose of this study was to help lay the foundation for further development of xylose-fermenting Saccharomyces cerevisiae yeast strains through an approach that combined metabolic engineering and random mutagenesis in a recombinant haploid strain that overexpressed only two genes of the xylose pathway. Previously, S. cerevisiae strains, overexpressing heterologous genes encoding xylose reduct

Cue words and the topic structure of spoken discourse: The case of Swedish men 'but'

The Swedish cue word men ‘but’ can mark the boundary between both different topic units as well as topic-internal units in spontaneous speech. The goal of this study is to see if these two functions of men can be distinguished on the basis of their local prosodic correlates and co-occurring lexical items. Men-tokens in spontaneous narrations were labelled as to their function, first using text-onl

Self-healing and self-organized gold nanoparticle films at a water/organic solvent interface

Gold nanoparticles (5 nm and 20 nm) have been synthesized and stabilized with mercaptoundecanol. These particles, although insoluble in water or common organic solvents, spread as a thin film at the liquid-liquid interface between a water phase and an organic phase. Films of these gold nanoparticles have been observed both by conventional transmission electron microscopy of deposited samples and b

Allozyme and chloroplast DNA variation in island and mainland populations of the rare Spanish endemic, Silene hifacensis (Caryophyllaceae)

Silene hifacensis is a narrowly endemic plant, restricted to a few small populations on limestone cliffs in the Spanish province of Alicante and on the Balearic island of Ibiza. The species was collected to extinction in its original mainland location by the early 20th century. Attempts have been made to reintroduce S. hifacensis to this area but conservation efforts are limited by a lack of infor

The effect of polymers on the phase behavior of balanced microemulsions: diblock-copolymer and comb-polymers

The effect of some amphipilic diblock-copolymers and comb-polymers on a balanced Winsor III microemulsion system is investigated with the quaternary system n-octyl-beta-D-glucoside/1-octanol/n-octane/D2O as basis system. The diblock-copolymers are polyethyleneoxide-co-polydodecenoxide (PEOx PEDODOy ) and polyethyleneoxide-co-polybutyleneoxide (PEO (x) PEBU (y) ), constituted of a straight chain hy

Frequency measures obtained from the surface electrocardiogram in atrial fibrillation research and clinical decision-making

Frequency Measures in AF. Introduction: Frequency analysis of fibrillation (FAF) and time-frequency analysis (TFA) were developed recently in order to quantify atrial electrical remodeling in atrial fibrillation (AF) from the surface ECG. This article describes the experience with these two different frequency analysis techniques in consecutive AF patients and discusses possible applications in AF

Trust in surveys and games - A methodological contribution on the influence of money and location

This paper explores methods to study trust. In a variety of settings, answers to survey questions and choices in a trust game are obtained from student sample pools. Some subjects are approached by mail and execute their task at home whereas others participate in classroom experiments. No differences between the results obtained by these methods are observed. Furthermore, one additional group play

Experimentally induced effects of heavy metal on microbial activity and community structure of forest mor layers

This study compared the toxic effects of adding chromium (Cr), zinc (Zn), lead (Pb), molybdenum (Mo), nickel (Ni), and cadmium (Cd) at three dose levels to mor layer samples in laboratory experiments. Microbial activity in the form of soil respiration was monitored for 64 days. At the end of the experimental period, the composition of the soil microbial community structure was analysed by phosphol

Pupil shapes and lens optics in the eyes of terrestrial vertebrates

Animal eyes that are primarily used under low-light conditions usually have optical systems of short depth of focus, such that chromatic defocus may lead to considerable blurring of the images. In some vertebrates, the problem is solved by multifocal lenses having concentric zones of different focal lengths, each of which focuses a different relevant spectral range onto the retina. A partially con
