Phosphatidylinositol 4-kinase serves as a metabolic sensor and regulates priming of secretory granules in pancreatic beta cells

Insulin secretion is controlled by the beta cell's metabolic state, and the ability of the secretory granules to undergo exocytosis increases during glucose stimulation in a membrane potential-independent fashion. Here, we demonstrate that exocytosis of insulin-containing secretory granules depends on phosphatidylinositol 4-kinase (PI 4-kinase) activity and that inhibition of this enzyme suppresse

Design issues and priorities in team and nonpharmacological arthritis care research

Nonpharmacologic and team care research present unique design challenges. Nonpharmacologic care by nature is multifaceted and complex. Rarely do patients receive an intervention in isolation. The delivery of a single or group of interventions can be provided by one provider but is frequently provided by teams. Therefore, it is imperative that clinical researchers design studies that evaluate singl

Analysing the Moran effect and dispersal: their significance and interaction in synchronous population dynamics

Population synchrony over various geographical scales is known from a large number of taxa. Three main hypotheses have been put forward as explanations to this phenomenon. First, correlated environmental disturbances (so called Moran effect). Moran showed that at least for linear models, the population synchrony would exactly match that of the corresponding environment. Second, the migration, or d

Prostate-specific antigen (PSA) protein does not affect growth of prostate cancer cells InVitro or prostate cancer xenografts in vivo

BACKGROUND. Prostate-specific antigen (PSA) is produced in high amounts by normal and malignant prostate cancer cells. PSA is a serine protease with substrates that include semenogelin I and II, insulin-like growth factor binding protein 3, fibronectin, and laminin. PSA, via its enzymatic activity, may play a role in growth, invasion, and metastasis of prostate cancer cells. Recent data also sugge

Introduction of human papillomavirus (HPV) vaccination in Sweden

The Swedish National Board of Health and Welfare (NBH) decided that a vaccine that protects against cervical cancer caused by human papillomavirus (HPV) should be included in the childhood vaccination directive as a nationwide-programme targeting 12-yearold girls from 2010 as a part of the school-health programme. Currently, vaccination of girls 13-18 years of age is covered by the public insuranc

An amperometric biosensor based on laccase immobilized in polymer matrices for determining phenolic compounds

An amperometric enzyme electrode based on laccase for determining phenolic compounds is proposed. The following three types of polymer materials were used for enzyme immobilization on the surface of a glassy-carbon electrode: positively charged cetyl ethyl poly (ethyleneimine) (CEPEI) and negatively charged commercial Nafion and Eastman AQ 29D polymers. The advantages and disadvantages of each of

Large eddy simulations of a turbulent thermal plume

Large eddy simulations of a three-dimensional turbulent thermal plume in an open environment have been carried out using a self-developed parallel computational fluid dynamics code SMAFS (smoke movement and flame spread) to study the thermal plume's dynamics including its puffing, self-preserving and air entrainment. In the simulation, the sub-grid stress was modeled using both the standard Smagor

Suppression Pattern of Neutral Pions at High Transverse Momentum in Au plus Au Collisions at root S-NN=200 GeV and Constraints on Medium Transport Coefficients

For Au + Au collisions at 200 GeV, we measure neutral pion production with good statistics for transverse momentum, p(T), up to 20 GeV/c. A fivefold suppression is found, which is essentially constant for 5 < p(T) < 20 GeV/c. Experimental uncertainties are small enough to constrain any model-dependent parametrization for the transport coefficient of the medium, e. g., in the parton quenching mode

Wavelength shifts in solar-type spectra

Spectral-line displacements away from the wavelengths naively expected from the Doppler shift caused by stellar radial motion may originate as convective shifts (correlated velocity and brightness patterns in the photosphere), as gravitational redshifts, or perhaps be induced by wave motions. Absolute lineshifts, in the past studied only for the Sun, are now accessible also for other stars thanks

Time to pregnancy and pregnancy outcome.

Objective: To investigate whether the outcome of a pregnancy is related to the time required to achieve that pregnancy (TTP). Design: The distribution of the TTP for pregnancies ending in multiple birth, early (before week 12) and late (weeks 12-28) miscarriage, stillbirth, and extrauterine pregnancy was compared to that of pregnancies ending in singleton birth. Furthermore, the distribution of th

Modelling CH4 emissions from arctic wetlands: effects of hydrological parameterization

This study compares the CH4 fluxes from two arctic wetland sites of different annual temperatures during 2004 to 2006. The PEATLAND-VU model was used to simulate the emissions. The CH4 module of PEATLAND-VU is based on the Walter-Heimann model. The first site is located in northeast Siberia, Indigirka lowlands, Kytalyk reserve (70 degrees N, 147 degrees E) in a continuous permafrost region with me

Results of three comparative test series for determining the fracture energy GF of concrete

RILEM Technical Committee 50—Fracture Mechanics of Concrete, has put forward a proposal for a recommendation for the determination of the fracture energy GF of mortar and concrete. In connection with the above three comparative test series were arranged in order to collect information and experience regarding the proposed method. 14 laboratories from 9 countries were involved and about 700 beams w

Effects of norethisterone acetate addition to estradiol in long term HRT

OBJECTIVE: The aim of this study was to evaluate the efficacy and tolerability of hormone replacement therapy (HRT) among postmenopausal women living in the Lund area of Southern Sweden and to analyze treatment effects in different types or routes of HRT administration, as well as to compare with unopposed estrogen therapy. METHOD: in an ongoing, large population-based, prospective cohort study, t

High-gain Soft-x-ray Pumped Photoionization Laser in Zinc Vapor

Large inversion densities in Zn+ have been produced by photoionizing inner #x2010;shell d electrons with the broadband soft #x2010;x #x2010;ray flux from a 1.06 #x2010; #x3bc;m laser #x2010;produced plasma. This pumping scheme is an effective technique for rapidly producing large population densities (5 #xd7;1013 cm-3) in the 3d9 #x2009;4s2 #x2009;2D5/2 upper laser level. These large densities (a)

fMRI activity in the medial temporal lobe during famous face processing

The current event-related fMRI study examined the relative involvement of different parts of the medial temporal lobe (MTL), particularly the contribution of hippocampus and perirhinal cortex, in either intentional or incidental recognition of famous faces in contrast to unfamiliar faces. Our intention was to further explore the controversial contribution of MTL in the processing of semantic memor

Early Pregnancy Azathioprine Use and Pregnancy Outcomes

BACKGROUND: Azathioprine (AZA) is used during pregnancy by h omen with inflammatory bowel disease (IBD), other autoimmune disorders, malignancy, and organ transplantation. Previous studies have demonstrated potential risks. METHODS: The Swedish Medical Birth Register was used to identify 476 women who reported the use of AZA in early pregnancy. The effect of AZA exposure on pregnancy outcomes was

Who owns the child in hospital? A preliminary discussion

Aim. To 'own' a person is considered an infringement of human rights, but we suggest that concepts of ownership influence interactions between parents and staff when a child is admitted to hospital. This paper aims to stimulate debate and contains an explanation of the exploration of the literature for research and discussion of ownership of the child. Method. A wide variety of library indexes, da

Geotrichum bryndzae sp nov., a novel asexual arthroconidial yeast species related to the genus Galactomyces

Ten strains of an asexual arthroconidial yeast species were isolated from Bryndza, a traditional Slovak artisanal sheep cheese, which was manufactured from raw milk during a 4-month summer production period at two Slovakian sites (the northern Ruzomberok and the central-southern Tisovec areas). Sequence comparison of the D1/D2 domains of the large-subunit rRNA gene revealed that this yeast represe
