The ubiquitous NF-kappaB transcription factor has been reported to inhibit apoptosis and to induce drug resistance in cancer cells. Drug resistance is the major reason for cancer therapy failure and neoplastic cells often develop multiple mechanisms of drug resistance during tumor progression. We observed that NF-kappaB or P-glycoprotein inhibition in the HCT15 colon cancer cells led to increased apoptotic cell death in response to daunomycin treatment. Interestingly, NF-kappaB inhibition through transfection of a plasmid coding for a mutated IkappaB-alpha inhibitor increased daunomycin cell uptake. Indeed, the inhibition of NF-kappaB reduced mdr1 mRNA and P-glycoprotein expression in HCT15 cells. We identified a consensus NF-kappaB binding site in the first intron of the human mdr1 gene and demonstrated that NF-kappaB complexes could bind with this intronic site. Moreover, NF-kappaB transactivates an mdr1 promoter luciferase construct. Our data thus demonstrate a role for NF-kappaB in the regulation of the mdr1 gene expression in cancer cells and in drug resistance. [less ▲]

Recently, Stallard and coworkers observed an event in Jupiter's auroral polar regions that resulted in a temperature increase of around 125K during the period of approximately seven jovian rotations [1]. This "auroral event" involves a great deal of energy being deposited in the upper atmosphere - up to 250mW m[SUP]-2[/SUP]. Stallard et al. made these measurements using H_3^+ emission lines from the fundamental (v=1 rightarrow 0) and hotband (v=2 rightarrow 1) manifolds around 4μm. In this poster, we use the temperature profiles developed by Grodent and coworkers [2] in their one-dimensional model of the jovian aurorae to demonstrate that the lines used by Stallard et al. are formed at different altitudes in the atmosphere: the hotband is formed higher than the fundamental. We show a series of profiles, based on Grodent {et al.}'s original model that can be used to interpret future jovian spectra. [1] T. Stallard et al., 2002. Icarus 156, 498-514. [2] D. Grodent, J.

Pseudomonas aeruginosa produces, under conditions of iron limitation, a high-affinity siderophore, pyoverdine (PVD), which is recognized at the level of the outer membrane by a specific TonB-dependent receptor, FpvA. So far, for P. aeruginosa, three different PVDs, differing in their peptide chain, have been described (types I-III), but only the FpvA receptor for type I is known. Two PVD-producing P. aeruginosa strains, one type II and one type III, were mutagenized by a mini-TnphoA3 transposon. In each case, one mutant unable to grow in the presence of the strong iron chelator ethylenediaminedihydroxyphenylacetic acid (EDDHA) and the cognate PVD was selected. The first mutant, which had an insertion in the pvdE gene, upstream of fpvA, was unable to take up type II PVD and showed resistance to pyocin S3, which is known to use type II FpvA as receptor. The second mutant was unable to take up type III PVD and had the transposon insertion in fpvA. Cosmid libraries of the respective type II and type III PVD wild-type strains were constructed and screened for clones restoring the capacity to grow in the presence of PVD. From the respective complementing genomic fragments, type II and type III fpvA sequences were determined. When in trans, type II and type III fpvA restored PVD production, uptake, growth in the presence of EDDHA and, in the case of type II fpvA, pyocin S3 sensitivity. Complementation of fpvA mutants obtained by allelic exchange was achieved by the presence of cognate fpvA in trans. All three receptors posses an N-terminal extension of about 70 amino acids, similar to FecA of Escherichia coli, but only FpvAI has a TAT export sequence at its N-terminal end. [less ▲]

We report on two sisters who show a similar pattern of anomalies consisting of bilateral Stilling-Turk-Duane retraction syndrome (type 3), non-progressive hypotonia with delayed motor milestones but normal intelligence, severe, early onset scoliosis, and short stature. Muscular biopsy revealed numerous regenerating fibers, but no specific abnormalities among the non-regenerating fibers. This combination of anomalies has not been previously reported, and could represent a new autosomal recessive syndrome. The only differential diagnosis is Crisfield-Dretakis-Sharpe syndrome, a combination of lateral gaze palsy, ptosis, and scoliosis without hypotonia, recessively inherited. [less ▲]

A new transition-metal-containing Zintl compound, Eu10Mn6Sb13, was prepared by a high-temperature Sn-flux synthesis. The structure was determined by single-crystal X-ray diffraction. Eu10Mn6Sb13 crystallizes in the monoclinic space group C2/m with a = 15.1791(6) Angstrom, b = 19.1919(7) Angstrom, c = 12.2679(4) Angstrom, beta = 108.078(1)degrees, Z = 4 (R1 = 0.0410, wR2 = 0.0920), and T = 90(2) K. The structure of Eu10Mn6Sb13 is composed of double layers of Mn-centered tetrahedra separated by Eu2+ cations. The double layers are composed of edge- and corner-sharing Mn-centered tetrahedra which form cavities occupied by Eu2+ cations and [Sb-2](4-) dumbbells. Linear [Sb-3](5-) trimers bridging two tetrahedra across the cavity are also present. Bulk susceptibility data indicate paramagnetic behavior with a ferromagnetic component present below 60 K. Temperature-dependent electrical resistivity measurements show semiconducting behavior above 60 K (E-a = 0.115(2) eV), a large and unusually sharp maximum in the resistivity at similar to40 K, and metallic behavior below 40 K. Eu-151 Mossbauer spectra confirm that the europium is divalent with an average isomer shift of -11.2(1) mm/s at 100 K; the spectra obtained below 40 K reveal magnetic ordering of six of the seven europium sublattices and, at 4.2 K, complete ordering of the seven europium sublattices.

High Speed Steel (HSS) cast rolls are used in front finishing stands of hot strip mills. Good wear resistance and hardness at high temperatures, are defining features of HSS. Many types of carbides are present in these alloys, each having different effect upon their final properties. As a result, nature, morphology and amount of these carbides are factors of important concern. Identification and characterisation of carbides were realised. MC, M2C, M7C3 carbides were found. Some relationships with mechanical properties were obtained especially in the field of the solidification sequence that affects grain size and carbides dispersion. [less ▲]

De jeunes pousses de Peuplier Ghoy ont été maintenues artificiellement inclinées pendant des durées croissantes, afin d’induire la formation de tissus de bois de tension et de bois opposé en réaction au stimulus gravitationnel. Il apparaît que ces pousses sont susceptibles de percevoir et de réagir à un stimulus extrêmement bref à l’échelle d’une période de végétation. Après un temps de présentation de 6 heures, l’ensemble des pousses ont formé un arc de bois opposé. Toutefois, sur la face supérieure, un temps compris entre 24 et 48 heures est nécessaire pour qu’elles perçoivent la modification de leur état d’équilibre et se mettent à former du bois de tension. Après un temps de latence de 48 heures, la formation de fibres gélatineuses est déjà observée sur la face supérieure des tiges. L’augmentation de la durée du stimulus a des répercussions sur le nombre de fibres gélatineuses et sur l’angle d’ouverture de l’arc de bois de tension. Sur la face inférieure, les fibres de bois opposé se forment à un rythme moins soutenu, conduisant à une excentricité de la moelle dans la section de la tige. Le redressement des pousses est effectif après une durée de stimulus comprise entre 4 et 8 jours. [less ▲]

A time–frequency method is proposed for the analysis of response time histories from nonlinear aeroelastic systems. The approach is based on a time-varying curve-fit of the short time Fourier transform of the impulse response. It is shown that the method can be used in order to obtain a clear picture of the sub-critical stability of a number of aeroelastic systems with a variety of structural and aerodynamic nonlinearities. Additionally, frequency and amplitude information can be obtained for both the linear and nonlinear signatures of the response signals in the sub- and postcritical regions. Finally, it is shown that, given certain types of nonlinear functions, sub-critical damping trends can be extrapolated to predict bifurcation airspeeds. [less ▲]
