A disgust mood state causes a negative interpretation bias, but not in the specific domain of body-related concerns.

The present study was designed to examine the effects of a disgust mood state on negative interpretation bias, in particular in the domain of body and weight concerns. Participants (N = 120) were randomly assigned to one of four mood induction groups (i.e.

A novel approach for generating full-length, high coverage allele libraries for the analysis of protein interactions.

The yeast reverse two-hybrid method was developed to identify mutations disrupting protein-protein interactions. Adoption of the method has been slow, in large part, due to the high frequency of truncation and frameshift mutants typically observed with current protocols. We have developed a new strategy, based on in vitro recombinational cloning and full-length selection in Escherichia coli, to eliminate this background and dramatically increase the efficiency of the reverse two-hybrid protocol.

Measurement of spin-correlation parameters ANN, ASS, and ASL at 2.1 GeV in proton-proton elastic scattering.

At the Cooler Synchrotron COSY/Jülich spin-correlation parameters in elastic proton-proton (pp) scattering have been measured with a 2.11 GeV polarized proton beam and a polarized hydrogen atomic beam target. We report results for A(NN), A(SS), and A(SL) for c.

Excitation functions of the analyzing power in pp--> scattering from 0.45 to 2.5 GeV.

Excitation functions A(N)(p(p),Theta(c.m.)) of the analyzing power in pp--> elastic scattering have been measured with a polarized atomic hydrogen target for projectile momenta p(p) between 1000 and 3300 MeV/ c.

Silicon-responsive cDNA clones isolated from the marine diatom Cylindrotheca fusiformis.

In organisms ranging from single-celled algae to mammals, including humans, silicon is essential for, and actively participates in, a variety of life processes. It has become clear that silicon (i) acts as a metabolite affecting a variety of cellular processes, and (ii) regulates gene expression. However, the mechanisms by which silicon (i.

Cytokine- and calcium ionophore A23187-mediated arachidonic acid metabolism in neutrophils.

Arachidonic acid (AA) metabolism is implicated as an intracellular and/or intercellular second messenger system for the transmission of cytokine-initiated signals that affect neutrophils and mediate systemic toxicity. The purpose of the present study is to ascertain if cytokines that are known to affect neutrophil function in vivo and in vitro directly stimulate neutrophil AA metabolism in vitro. The recombinant human cytokines multi-colony stimulating factor, granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin 1, tumor necrosis factor (TNF), and interleukin 6 and the calcium ionophore A23187 were incubated with purified 14C-AA radiolabeled human peripheral blood neutrophils and the effects were assayed by one- and two-dimensional thin layer lipid chromatography.

Acute and subacute hematologic effects of multi-colony stimulating factor in combination with granulocyte colony-stimulating factor in vivo.

Multi-colony stimulating factor (Multi-CSF, interleukin-3, IL-3) and granulocyte-CSF (G-CSF) administered concurrently as an intravenous (IV) injection induce a peripheral neutrophilia that is approximately additive in comparison with the neutrophilia induced by IL-3 and G-CSF individually. The bone marrow (BM) at 12 hours is depleted of mature neutrophils and shows a left-shifted myeloid hyperplasia, consistent with the neutrophil-releasing and myeloproliferative activities of both IL-3 and G-CSF individually. The BM at 24 hours shows a replenished reserve of mature neutrophils and a synergistic left-shifted myeloid hyperplasia as compared with IL-3 and G-CSF alone.

Acute in vivo effects of IL-3 alone and in combination with IL-6 on the blood cells of the circulation and bone marrow.

Recombinant human IL-3 administered intravenously to rats as a single injection induced peripheral neutrophilia and monocytosis beginning at 4 to 6 hours after injection, peaking at 8 hours, and subsiding to normal by 12 to 24 hours. IL-3 did not induce an initial neutropenia such as accompanies endotoxin-, G-CSF-, and TNF-induced neutrophilia, or lymphopenia such as accompanies endotoxin-, IL-1-, and TNF-induced neutrophilia. The IL-3-induced peripheral neutrophilia was accompanied by a decrease in mature marrow neutrophils, indicating that the mechanism of neutrophilia was through marrow release rather than by demargination, which occurs after the administration of epinephrine or IL-6.
