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

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

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

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

Dark-bellied Brent Geese Branta bernicla bernicla, as recorded by satellite telemetry, do not minimize flight distance during spring migration

Nine Dark-bellied Brent Geese Branta bernicla bernicla were equipped with satellite transmitters during spring staging in the Dutch Wadden Sea in 1998 and 1999. The transmitters (in all cases less than 3% of body mass) were attached to the back by a flexible elastic harness. One juvenile female was tracked to the Yamal peninsula in 1998. Eight adult males were selected from a single catch of 75 to

Molecular analysis of simple variant translocations in acute promyelocytic leukemia

The primary cytogenetic abnormality in acute promyelocytic leukemia (APL; FAB M3) is a reciprocal translocation, t(15;17)(q22;q12), which serves to fuse the PML gene on chromosome 15 to the retinoic acid receptor alpha (RARA) gene on chromosome 17. A PML-RARA fusion message transcribed from the der(15) is thought to mediate leukemogenesis. Two APL patients with simple variants of this translocatio

A variant associated with nicotine dependence, lung cancer and peripheral arterial disease

Smoking is a leading cause of preventable death, causing about 5 million premature deaths worldwide each year(1,2). Evidence for genetic influence on smoking behaviour and nicotine dependence (ND)(3-8) has prompted a search for susceptibility genes. Furthermore, assessing the impact of sequence variants on smoking-related diseases is important to public health(9,10). Smoking is the major risk fact

Physical Properties of Escherichia coli P Pili Measured by Optical Tweezers

The mechanical behavior of individual P pili of uropathogenic Escherichia coli has been investigated using optical tweezers. P pili, whose main part constitutes the PapA rod, composed of 103 PapA subunits in a helical arrangement, are distributed over the bacterial surface and mediate adhesion to host cells. They are particularly important in the pathogenesis of E. coli colonizing the upper urinar

Method for ultrastructural studies of the intact tissue-metal interface

Samples were prepared for ultrastructural studies of the intact interface between metallic implants and tissue by transmission electron microscopy. The method is based on plastic embedding of implant and tissue and subsequent removal of the bulk metal by electrochemical dissolution (electropolishing), to facilitate preparation of ultrathin sections for transmission electron microscopy. Surface sen

Cursorial spiders retard initial aphid population growth at low densities in winter wheat

Generalist predators contribute to pest suppression in agroecosystems. Spider communities, which form a substantial fraction of the generalist predator fauna in arable land, are characterized by two functional groups: web-building and cursorial (non-web-building) species. We investigated the relative impact of these two functional groups on a common pest (Sitobion avenae, Aphididae) in wheat by co

Selective attenuation of neuropeptide-Y-mediated contractile responses in blood vessels from patients with diabetes mellitus

Vascular smooth muscle contractile responses to neuropeptide Y, alpha,beta-methyleneATP and noradrenaline were studied in circular segments of isolated vessels with intact endothelium in vitro from 12 patients with diabetes mellitus type 2 (NIDDM) and 12 control subjects. The dilatory effect of acetylcholine was used to test the function of the endothelium. Subcutaneous arteries and veins (diamete

Predator behaviour and prey density: evaluating density-dependent intraspecific interactions on predator functional responses

1. In models of size-structured predator-prey systems, the effects are evaluated of gape-size limited predation on prey population growth and density when predators are non-interacting, cannibalistic, interfering, and cannibalistic and interfering. 2. Predation from non-interacting predators markedly reduces prey density, compared with prey densities in the absence of predation. When density-depen

Parental care and social mating system in the Lesser Spotted Woodpecker Dendrocopos minor

The sexes' share in parental care and the social mating system in a marked population of the single-brooded Lesser Spotted Woodpecker Dendrocopos minor were studied in 17 woodpecker territories in southern Sweden during 10 years. The birds showed a very strong mate fidelity between years; the divorce rate was 3.4%. In monogamous pairs, the male provided more parental care than the female. The male

Use of pollution-induced community tolerance of the bacterial community to detect phenol toxicity in soil.

Pollution-induced community tolerance (PICT) was used to study effects of phenol on soil bacteria. Phenol was added to an agricultural soil in a microcosm experiment. The effects were studied for up to four months. Bacterial growth rates were estimated with the leucine incorporation technique. This technique was also used as detection method for PICT. Changes in community structure were studied us

Development and Reliability Testing of the Nordic Housing Enabler - An Instrument for Accessibility Assessment of the Physical Housing

For decades, accessibility to the physical housing environment for people with functional limitations has been of interest politically, professionally and for the users Guidelines and norms on accessible housing design have gradually been developed, however the built environment shows serious deficits when it comes to accessibility This study addresses development of a content valid cross Nordic v
