Correlation effects

The current study sought to determine: If there is a correlation between conventional measures of lung function such as Forced Expiratory Volume in one second (FEV1) and less conventional measures such as airways expired NO level (eNO), electrodermal measures, TCM enquiry and BHT; If any of the lung function measures are able to distinguish between asthmatic and healthy subjects; If the use of a rye grass extract is better than placebo in improving requirements for bronchodilator medication, peak flow, forced expiratory volume in one second or quality of life in mild to moderate childhood a...

This dissertation is composed of two parts, an integrative essay and a set of published papers. The essay and the collection of papers are placed in the context of development and application of time series econometric models in a temporal-axis from 1970s through 2005, with particular focus in the Marketing discipline. The main aim of the integrative essay is on modelling the effects of marketing actions on performance variables, such as sales and market share in competitive markets.

Analytical expressions for the anharmonic effective potential, local force constant, Displacement-displacement Correlation Function (DCF) CR and Debye-Waller factor described by the Mean Square Relative Displacement (MSRD) σ2 and by the Mean Square Displacement (MSD) u2of bcc crystals in the X-ray Absorption Fine Structure (XAFS) have been derived. The effective interatomic potential of the system has been considered by taking into account the influences of nearest atomic neighbors, and it contains the Morse potential characterizing the interaction of each pair of atoms.

In this paper, we present a numerical analysis of the effect of different heat transfer correlations on the prediction of the cladding wall temperature in a supercritical water reactor at nominal operating conditions. The neutronics process with temperature feedback effects, the heat transfer in the fuel rod, and the thermal-hydraulics in the core were simulated with a three-pass core design.

The studies presented in this paper are performed in the general framework of transient coupled calculations with accurate neutron kinetics models able to characterize spatial decoupling in the core. An innovative fission matrix interpolation model has been developed with a correlated sampling technique associated to the Transient Fission Matrix (TFM) approach.

Construction of bounds on the elastic moduli of isotropic multicomponent materials which involve three-point correlation parameters. We use numerical methods to study several representative material models. Construction of three-point correlation bounds on the effective elastic shear modulus of composite materials and applications of the bounds are given to some composites.

Prolyl endopeptidase (PEP) is a proline-specific oligopepti-dase with a reported effect on learning and memory in dif-ferent rat model systems. Using the astroglioma cell line U343,PEP expression was reduced by an antisense technique. Measuring different second-messenger concen-trations revealed an inverse correlation between inositol 1,4,5-triphosphate [Ins(1,4,5)P3] concentration and PEP expression in the generated antisense cell lines. However,no effect on cAMP generation was observed.

To learn about the correlation between allostery and ligand binding of the Tet repressor (TetR) we analyzed the effect of mutations in the DNA read-ing head–core interface on the effector specific TetR i2 variant. The same mutations in these subdomains can lead to completely different activities, e.g. the V99G exchange in the wild-type leads to corepression by 4-ddma-atc without altering DNA binding. However, in TetR i2 it leads to 4-ddma-atc dependent repression in combination with reduced DNA binding in the absence of effector. ...

The dementia familial encephalopathy with neuroserpin inclusion bodies (FENIB) is caused by point mutations in the neuroserpin gene.We have shown a correlation between the predicted effect of the mutation and the number of intracerebral inclusions, and an inverse relationshipwith the age of onset of disease. Our previous work has shown that the intraneuronal inclusions in FENIB result from the sequential interactionbetween the reactive centre loopofone neuroserpin molecule withb-sheet A of the next. ...

Circular dichroism (CD) spectra of two major hemoglobin components (Hb), HbI and HbIV, from Oncorhyncus mykiss(formerly Salmo irideus) trout were evaluated in the range 250–600 nm. HbI is characterized by a complete insensitivity to pH changes, while HbIV presents the Root effect. Both reduced [iron(II) or oxy] and oxidized (met) forms of the two proteins were studied at different pHs, 7.8 and 6.0, to obtain information about the pH effects on the structural features of these hemoglobins.

Benzo[a]pyrene (B[a]P) is a common food pollutant that causes DNA adduct formation and is carcinogenic. The report of a positive correlation between human plasma B[a]P levels and body mass index, together with B[a]P’s lipophilicity, led us to test for possible adverse effects of B[a]P on adipose tissue.

G-rich GT oligonucleotides with a different content of G clusters have been evaluated for their ability to exert cytotoxicity and to bind to nuclear-associated proteins in T-lymphoblast CCRF-CEM cells. Only the oligomers that did not form G-based structures or had a poor structure, under physiological conditions, were able to exert significant cellular growth inhibition effect.

Both microtubule destabilizer and stabilizer agents are important molecules in anticancer therapy. In particular, paclitaxel has been demonstrated to be effective for the treatment of ovarian, breast, and nonsmall cell lung carci-nomas. It has been shown that emergence of resistance against this agent correlates with an increase in the relative abundance of tubulin isoform bIII and that the more recently discovered IDN5390 can be effectively used once resistance has emerged.

Neokyotorphin [TSKYR, hemoglobina-chain fragment (137–141)] has pre-viously been shown to enhance fibroblast proliferation, its effect depending on cell density and serum level. Here we show the dependence of the effect of neokyotorphin on cell type and its correlation with the effect of protein kinase A (PKA) activator 8-Br-cAMP, but not the PKC activator 4b-phor-bol 12-myristate, 13-acetate (PMA).

We used generalized two-dimensional NMR–NMR correlation to examine the effect of potassium ions on the conformation transition in silk fibroin to investigate the possibility that the fairly high K + ion content found in the distal end of silk-secreting ducts in the silkworms could have a bearing on natural formation of the silk fiber.
