description: The omnipresence of dust particulates in space and astrophysical plasmas has been attracting numerous researchers to study the collective excitation and propagation dynamics of different eigen-mode structures in diversifed astrocosmic circumstances for years. It includes planetary rings, interplanetary space, cometary tails, asteroid zones, planetary atmospheres, etc. The ubiquitous charged dust particulates possess collective degrees of dynamic freedom resulting in the excitation of relatively low-frequency modes, such as dust-ion-acoustic waves (DIAWs), dust-acoustic waves (DAWs), dust-Coulomb waves (DCWs), and so forth. An interesting prevalency of dusty plasma stability research lies in the Jovian magnetosphere (i.e., Jovian plasmas), embedded inside the supersonic solar wind. A brief review of the updated research works on dust-acoustic waves and related collective instability dynamics in the presence of trapped plasma particles is presented herein. The key aim of the proposed explorative meta-analysis is rooted in outlining concisely the main up-to-date investigations on such collective instability processes chronologically. An especial attention is given primarily to the thermostatistical distribution laws of the constitutive lighter electrons and ions against the heavier positively charged dust grains (microspheres). The trapping mechanism of both the lighter species (electrons+ions) is another additive feature revisited here properly. Finally, we clearly extrapolate a number of futuristic directions in light of sensible novelties with a wider scope, both horizontally as well as vertically.

Mentalism, Behavior-Behavior Relations, and a Behavior-Analytic View of the Purposes of Science
Creators: name: Hayes, Steven C.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: In a behavioral view, the purposes of science are primarily prediction and control. To the extent that a scientist embraces both of these as a unified and generally applicable criterion for science, certain philosophical and theoretical practices are counterproductive, including mentalism in both its metaphysical and metatheoretical forms. It is possible and often worthwhile to recast some mentalistic talk into an issue of behavior-behavior relations. When behavior-behavior relations are approached non-mechanistically, however, analysis cannot stop at the level of the relations themselves. Several analytic concepts common in the behavioral community share some of the dangers of mentalism if not employed properly, including such concepts as self-reinforcement, response-produced stimulation, and self-rules.

description: Recent reform in the National Health Service has moved general practice towards a more intense market and competition structure. Meanwhile in the United States of America there has been an attempt to modify the free enterprise approach to medical care towards a more socially responsive system. This discussion paper provides a family doctor's perspective of primary care and the maelstrom of health care reform in the USA. The cultural, economic and organizational issues underlying the need for reform are considered in turn, and the current situation with regard to health care provision, medical research, medical education and primary care are outlined. General practitioners in the United Kingdom would do well to pay attention to the effects of market reform occurring in general practice among their American counterparts.

description: A light singlino in the NMSSM can reduce considerably the missing transverse energy at the end of sparticle decay cascades; instead, light NMSSM-specific Higgs bosons can be produced. Such scenarios can be consistent with present constraints from the LHC with all sparticle masses below ~1 TeV. We discuss search strategies, which do not rely on missing transverse energy, for such scenarios at the next run of the LHC near 14 TeV.

description: An indispensable part of our lives, computing has also become essential to industries and governments. Steady improvements in computer hardware have been supported by periodic doubling of transistor densities in integrated circuits over the last fifty years. Such Moore scaling now requires increasingly heroic efforts, stimulating research in alternative hardware and stirring controversy. To help evaluate emerging technologies and enrich our understanding of integrated-circuit scaling, we review fundamental limits to computation: in manufacturing, energy, physical space, design and verification effort, and algorithms. To outline what is achievable in principle and in practice, we recall how some limits were circumvented, compare loose and tight limits. We also point out that engineering difficulties encountered by emerging technologies may indicate yet-unknown limits.

description: Swarm intelligence is a discipline that studies the collective behavior that is produced by local interactions of a group of individuals with each other and with their environment. In Computer Science domain, numerous swarm intelligence techniques are applied to optimization problems that seek to efficiently find best solutions within a search space. Gradual pattern mining is another Computer Science field that could benefit from the efficiency of swarm based optimization techniques in the task of finding gradual patterns from a huge search space. A gradual pattern is a rule-based correlation that describes the gradual relationship among the attributes of a data set. For example, given attributes {G,H} of a data set a gradual pattern may take the form: "the less G, the more H". In this paper, we propose a numeric encoding for gradual pattern candidates that we use to define an effective search space. In addition, we present a systematic study of several meta-heuristic optimization techniques as efficient solutions to the problem of finding gradual patterns using our search space.

description: Though ~10 Earth mass rocky/icy cores are commonly held as a prerequisite for the formation of gas giants, theoretical models still struggle to explain how these embryos can form within the lifetimes of gaseous circumstellar disks. In recent years, aerodynamic-aided accretion of "pebbles," objects ranging from centimeters to meters in size, has been suggested as a potential solution to this long-standing problem. While pebble accretion has been demonstrated to be extremely effective in local simulations that look at the detailed behavior of these pebbles in the vicinity of a single planetary embryo, to date there have been no global simulations demonstrating the effectiveness of pebble accretion in a more complicated, multi-planet environment. Therefore, we have incorporated the aerodynamic-aided accretion physics into LIPAD, a Lagrangian code that can follow the collisional / accretional / dynamical evolution of a protoplanetary system, to investigate how pebble accretion manifests itself in the larger planet formation picture. We find that under generic circumstances, pebble accretion naturally leads to an "oligarchic" type of growth in which a large number of planetesimals grow to similar-sized planets. In particular, our simulations tend to form hundreds of Mars- and Earth-mass objects between 4 and 10 AU. While the merging of some oligarchs may allow them to grow massive enough to form giant planet cores, leftover oligarchs lead to planetary systems that cannot be consistent with our own solar system. We investigate various ideas presented in the literature (including evaporation fronts and planet traps) and find that none easily overcome this tendency toward oligarchic growth.

description: We present 4 new transit observations of the exoplanet WASP-28b observed between August 2011 and October 2013. Employing another 11 transits available in the literature we compute new ephemeris and redetermine the physical parameters of the star and the exoplanet. Considering 3 yrs of observations, we find no periodic TTVs or long-term variations of the inclination of the orbit, i, or the depth of the transit, k, that could be attributable to the presence of another planetary mass-body in the system. We also study the relations between i and k with different factors that characterize the light-curves. The fits suggest a possible weak correlation between k with the red noise factor, β, and the photometric noise rate, PNR, and a weak anticorrelation between i and PNR, although more points are needed to confirm these trends. Finally, the kinematic study suggests that WASP-28 is a thin disk star.

Four individuals of this molossid were captured, two on the OU ridge and two on the PF ridge. Fahr et al. (2006) mention an earlier record from Ziama. In Sierra Leone, it is known from 20 specimens from Gola Forest Camp (4 mi S Lalehun); and from Fadugu and Fintonia in the Northern Province (Grubb et al., 1998; Monadjem and Fahr, 2007: App. 11, USNM). Rosevear (1965: 337) stated that this species is widely distributed “from the arid Sahel woodland to the evergreen rainforest belt, though most of the records for the latter are from places where the forest has been much destroyed”. Natural roost sites are holes in trunks and branches of hollow trees, but this species has adapted to form large colonies in roofs and can “become a major pest in dwellings and stores” (Rosevear, 1965: 338). Conservation status Least Concern. A widely distributed and common species. Population trend unknown (IUCN, 2015).

description: We show that, quite generically, a [111] slab of spin-orbit coupled pyrochlore lattice exhibits surface states whose constant energy curves take the shape of Fermi arcs, localized to different surfaces depending on their quasimomentum. Remarkably, these persist independently of the existence of Weyl points in the bulk. Considering interacting electrons in slabs of finite thickness, we find a plethora of known fractional Chern insulating phases, to which we add the discovery of a new higher Chern number state which is likely a generalization of the Moore-Read fermionic fractional quantum Hall state. By contrast, in the three-dimensional limit, we argue for the absence of gapped states of the flat surface band due to a topologically protected coupling of the surface to gapless states in the bulk. We comment on generalizations as well as experimental perspectives in thin slabs of pyrochlore iridates.

description: We have developed a simple and efficient transformation system for the agaric fungus, Coprinus cinereus. Protoplasts were prepared from asexual spores that harbor one or two mutations in the structural gene for tryptophan synthetase. The protoplasts can be stably transformed using the cloned Coprinus gene at a frequency of 1 in 10(4) viable protoplasts. A variety of molecular events accompanies the formation of stable transformants, including insertion of the transforming DNA at the homologous locus. The transforming DNA is stable through cell division, mating, fruiting body formation, and meiosis.

description: The LSP1-alpha gene of Drosophila melanogaster is located on the X chromosome at 11B yet is not dosage compensated. In order to determine if this gene is inherently incapable of dosage compensation or if it does not compensate because the appropriate regulatory cis-acting sequences are absent from its chromosomal domain, we have undertaken to relocate it to ectopic sites on the X chromosome. To differentiate between the transcripts produced by the transduced gene and those produced by the indigenous gene, we inserted a 500-bp sequence of mouse DNA into the LSP1-alpha clone prior to using it for transformation. Our results show that the LSP1-alpha gene exhibits equivalent levels of transcripts in the two sexes when it is relocated to either an autosomal site or to an ectopic site on the X chromosome. We conclude that the LSP1-alpha gene is capable of dosage compensation.

description: Machine learning (ML) is revolutionizing the world, affecting almost every field of science and industry. Recent algorithms (in particular, deep networks) are increasingly data-hungry, requiring large datasets for training. Thus, the dominant paradigm in ML today involves constructing large, task-specific datasets. However, obtaining quality datasets of such magnitude proves to be a difficult challenge. A variety of methods have been proposed to address this data bottleneck problem, but they are scattered across different areas, and it is hard for a practitioner to keep up with the latest developments. In this work, we propose a taxonomy of these methods. Our goal is twofold: (1) We wish to raise the community's awareness of the methods that already exist and encourage more efficient use of resources, and (2) we hope that such a taxonomy will contribute to our understanding of the problem, inspiring novel ideas and strategies to replace current annotation-heavy approaches.

description: The type I Seyfert galaxy NGC 3227 was observed by Suzaku six times in 2008, with intervals of $\sim1$ week and net exposures of $\sim50$ ksec each. Among the six observations, the source varied by nearly an order of magnitude, being brightest in the 1st observation with a 2-10 keV luminosity of $1.2\times10^{42}$~erg~s$^{-1}$, while faintest in the 4th with $2.9\times10^{41}$~erg~s$^{-1}$. As it became fainter, the continuum in a 2-45 keV band became harder, while a narrow Fe-K$α$ emission line, detected on all occasions at 6.4 keV of the source rest frame, remained approximately constant in the photon flux. Through a method of variability-assisted broad-band spectroscopy (e.g., Noda et al. 2013), the 2-45 keV spectrum of NGC 3227 was decomposed into three distinct components. One is a relatively soft power-law continuum with a photon index of $\sim 2.3$, weakly absorbed and highly variable on time scales of $\sim5$ ksec; it was observed only when the source was above a threshold luminosity of $\sim6.6 \times10^{41}$ erg s$^{-1}$ (in 2-10 keV), and was responsible for further source brightening beyond. Another is a harder and more absorbed continuum with a photon index of $\sim 1.6$, which persisted through the six observations and varied slowly on time scales of a few weeks by a factor of $\sim2$. This component, carrying a major fraction of the broad-band emission when the source is below the threshold luminosity, is considered as an additional primary emission. The last one is a reflection component with the narrow iron line, produced at large distances from the central black hole.

Three pure chaperone proteins of Escherichia coli--SecB, trigger factor and GroEL--form soluble complexes with precursor proteins in vitro.
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: Diverse studies of three cytoplasmic proteins of Escherichia coli--SecB, trigger factor and GroEL--have suggested that they can maintain precursor proteins in a conformation which is competent for membrane translocation. These proteins have been termed 'chaperones'. Using purified chaperone proteins and precursor protein substrates, we find that each of these chaperones can stabilize proOmpA for translocation and for the translocation-ATPase. These chaperones bind to proOmpA to form isolable complexes. SecB and GroEL will also form complexes with another exported protein, prePhoE. In contrast, these chaperones do not form stable complexes with a variety of soluble proteins such as SecA protein, bovine serum albumin, ovalbumin or ribonuclease A. While chaperones may transiently interact with soluble proteins to catalyze their folding, the stable interaction between chaperones and presecretory proteins, maintaining an open conformation which is essential for translocation, may commit these proteins to the secretion pathway.
Characterization of nuclear localizing sequences derived from yeast ribosomal protein L29.
Creators: name: Fried, H
name: Underwood, M
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: Two particular seven-amino-acid segments from yeast ribosomal protein L29 caused a non-nuclear reporter protein to associate almost exclusively with the yeast nucleus. The two L29-derived nuclear localizing sequences were identical in five of the seven residues, many of which were basic amino acids. Generally, localization of the reporter protein was most impaired by replacement of the basic residues. A particular Arg residue was unique; substitution by any amino acid including Lys diminished nuclear localization of the reporter protein. In L29 the corresponding Arg 25----Lys substitution within the nuclear localizing sequence distal to the N-terminus was without effect, as evidence by normal rates of ribosome assembly and cell growth. However, the analogous Arg 8----Lys substitution within the localizing sequence proximal to the N-terminus led to greatly reduced rates of ribosome assembly and cell growth. Finally, when both localizing sequences contained the Arg----Lys substitution a still greater decrease in ribosome assembly and cell growth was observed. These results were as expected if the two short peptide sequences functioned in nuclear localization and/or assembly of yeast ribosomal protein L29.

A single male of this smallest West African molossid bat was captured in the canopy net over the creek in closed evergreen forest at FC and two females in the canopy net on the ridge at PF ridge. The specimen from PF carried an embryo of 20 mm crown-rump length. Verschuren (1976) recorded two individuals near the River Douoble at Liberian Mount Nimba. At Njala, Sierra Leone, nine adult females with three young were found roosting in a crack of a tree, others in a thatched roof and one in a bamboo thicket. Mops nanulus is considered a high forest and fringing forest species (Rosevear, 1965; Grubb et al., 1998). Upon the discovery of this species in DR Congo in 1917 seven individuals were found in a cavity high up in a tree, the entrance of which was concealed by epiphytic ferns (Allen et al., 1917). Our captures from the Foko Ridge show that this forest-dwelling molossid does leave the forest to hunt in open habitat. Conservation status Least Concern. Population trend is unknown (IUCN, 2015).

description: A protocol is proposed for the rapid coherent loading of a Bose-Einstein condensate into the ground state of an optical lattice, without residual excitation associated with the breakdown of adiabaticity. The driving potential required to assist the rapid loading is derived using the fast forward technique, and generates the ground state in any desired short time. We propose an experimentally feasible loading scheme using a bichromatic lattice potential, which approximates the fast-forward driving potential with high fidelity.

In situ analysis of myelin basic protein gene expression in myelin-deficient oligodendrocytes: antisense hnRNA and readthrough transcription.
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Mice homozygous for the recessive mutation myelin deficient (mld) exhibit a severe deficit in the synthesis of myelin basic protein (MBP). The primary defect in mld mice is an unusual rearrangement of the MBP gene. The mld MBP locus consists of two tandem MBP genes that span approximately 90 kb of DNA; the upstream gene contains an extensive inversion of its 3' region, while the downstream gene appears identical to the wild-type gene. In this report, the aberrant expression of the mld MBP locus was examined by in situ hybridization with MBP genomic and cDNA probes. In situ hybridization with a single-stranded genomic probe from the inverted region of the mld MBP gene revealed that primary transcripts initiating from the upstream MBP promoter elongate through the inverted region generating abundant antisense MBP heterogeneous nucleus RNA (hnRNA) transcripts in mld oligodendrocytes. Little or no antisense MBP RNA was detected in cytoplasmic regions in mld brain sections indicating that the antisense MBP hnRNA transcripts are not processed and transported out of the nucleus. Furthermore, we provide evidence that these abnormal transcripts elongate through the downstream MBP gene's promoter region, suggesting that transcription of the downstream mld MBP gene is inhibited by readthrough transcripts that originate at the upstream promoter.

description: The coupling between dark sectors provides a possible approach to mitigate the coincidence problem of cosmological standard model. In this paper, dark energy is treated as a fluid with a constant equation of state, whose coupling with dark matter is proportional the Hubble parameter and energy density of dark energy, that is, $\bar{Q}=3ξ_x\bar{H}\barρ_x$. Particularly, we consider the Hubble expansion rate to be perturbed in the perturbation evolutions of dark sectors. Using jointing data sets which include cosmic microwave background radiation, baryon acoustic oscillation, type Ia supernovae, and redshift-space distortions, we perform a full Monte Carlo Markov Chain likelihood analysis for the coupled model. The results show that the mean value with errors of interaction rate is: $ξ_x=0.00305_{-0.00305-0.00305-0.00305}^{+0.000645+0.00511+0.00854}$ for $Q^μ_A\parallel u^μ_c$; $ξ_x=0.00317_{-0.00317-0.00317-0.00317}^{+0.000628+0.00547+0.00929}$ for $Q^μ_A\parallel u^μ_x$, which means that the recently cosmic observations favored small interaction rate which is up to the order of $10^{-3}$. Moreover, in contrast to the coupled model with unperturbed expansion rate, we find perturbed Hubble expansion rate could bring about negligible impact on the model parameter space.

description: We consider the perturbative stability of non-supersymmetric configurations in N=1 supergravity models with a spectator sector not involved in supersymmetry breaking. Motivated by the supergravity description of complex structure moduli in Large Volume Compactifications of type IIB-superstrings, we concentrate on models where the interactions are consistent with the supersymmetric truncation of the spectator fields, and we describe their couplings by a random ensemble of generic supergravity theories. We characterise the mass spectrum of the spectator fields in terms of the statistical parameters of the ensemble and the geometry of the scalar manifold. Our results show that the non-generic couplings between the spectator and the supersymmetry breaking sectors can stabilise all the tachyons which typically appear in the spectator sector before including the supersymmetry breaking effects, and we find large regions of the parameter space where the supersymmetric sector remains stable with probability close to one. We discuss these results about the stability of the supersymmetric sector in two physically relevant situations: non-supersymmetric Minkowski vacua, and slow-roll inflation driven by the supersymmetry breaking sector. For the class of models we consider, we have reproduced the regimes in which the KKLT and Large Volume Scenarios stabilise all supersymmetric moduli. We have also identified a new regime in which the supersymmetric sector is stabilised at a very robust type of dS minimum without invoking a large mass hierarchy.

title: The Study and Application of Membrane Binding Supramolecular Self-associating Amphiphiles

description: With the looming threat of antimicrobial resistance (AMR) and the distinct absence of new antimicrobial agents on the market, the development of novel therapeutic treatments against AMR bacteria is vital. The work detailed herein demonstrates the potential for supramolecular self-associating amphiphiles (SSAs) to act as the first anionic antimicrobial potentiator of novobiocin (52) and rifampicin (53) against ESKAPE pathogen Pseudomonas aeruginosa. The most effective combination offered a dramatic 8-fold decrease of the MIC of novobiocin (52), from 3.2 mM to 0.4 mM in the presence of a non-inhibitory SSA concentration. Extensive physicochemical characterisation of SSA/antimicrobial interactions offer explanations for the observed synergistic behaviour. This thesis validates the hypothesis that SSAs are bacterial membrane disruptors through the employment of fluorescence spectroscopy. The urea benzothiazole SSAs were found to exhibit the highest level of broad range vesicle lysis, however a lack of correlation was observed between vesicle lysis and selective SSA: phospholipid interaction. The ability for SSAs to induce membrane fluidity was explored, revealing the carboxylate moiety over a sulfonate can selectively increase the membrane fluidity of bacterial model membranes over eukaryotic. Finally, a patch clamp method was optimised, providing insight into the potential transport mechanism of SSAs in the presence of an anionophore.

description: We experimentally demonstrate optical Mach-Zehnder interferometer utilizing displaced Sagnac configuration to enhance its phase stability. The interferometer with footprint of 27x40 cm offers individually accessible paths and shows phase deviation less than 0.4 deg during a 250 s long measurement. The phase drift, evaluated by means of Allan deviation, stays below 3 deg or 7 nm for 1.5 hours without any active stabilization. The polarization insensitive design is verified by measuring interference visibility as a function of input polarization. For both interferometer's output ports and all tested polarization states the visibility stays above 93%. The discrepancy in visibility for horizontal and vertical polarization about 3.5% is caused mainly by undesired polarization dependence of splitting ratio of the beam splitter used. The presented interferometer device is suitable for quantum-information and other sensitive applications where active stabilization is complicated and common-mode interferometer is not an option as both the interferometer arms have to be accessible individually.

description: The opacity of deep learning models constrains their debugging and improvement. Augmenting deep models with saliency-based strategies, such as attention, has been claimed to help get a better understanding of the decision-making process of black-box models. However, some recent works challenged saliency's faithfulness in the field of Natural Language Processing (NLP), questioning attention weights' adherence to the true decision-making process of the model. We add to this discussion by evaluating the faithfulness of in-model saliency applied to a video processing task for the first time, namely, temporal colour constancy. We perform the evaluation by adapting to our target task two tests for faithfulness from recent NLP literature, whose methodology we refine as part of our contributions. We show that attention fails to achieve faithfulness, while confidence, a particular type of in-model visual saliency, succeeds.

description: Based on the transport model isospin-dependent Boltzmann-Uehling-Uhlenbeck coupled with a phase-space coalescence afterburner, we studied the effects of the high-momentum tail (HMT) of nucleon momentum distribution in initialization in 197Au+197Au reactions at a beam energy of 400 MeV/nucleon with different impact parameters.We found remarkable impact parameter-dependent HMT effects on the fragment multiplicity distribution. The average neutron to proton ratio of produced isotopes is also affected by the HMT. The rapidity distributions of triton and 3He and their elliptic flows are all evidently affected by the HMT. All the effects of the HMT on the cluster production in heavy-ion collisions are centrality dependent.

description: The prlA/secY gene, which codes for an integral membrane protein component of the Escherichia coli protein export machinery, is the locus of the strongest suppressors of signal sequence mutations. We demonstrate that two exported proteins of E. coli, maltose-binding protein and alkaline phosphatase, each lacking its entire signal sequence, are exported to the periplasm in several prlA mutants. The export efficiency can be substantial; in a strain carrying the prlA4 allele, 30% of signal-sequence-less alkaline phosphatase is exported to the periplasm.The prlA/secY gene, which codes for an integral membrane protein component of the Escherichia coli protein export machinery, is the locus of the strongest suppressors of signal sequence mutations.

description: Symmetry energy, temperature and density at the time of the intermediate mass fragment formation are determined in a self-consistent manner, using the experimentally reconstructed primary hot isotope yields and anti-symmetrized molecular dynamics (AMD) simulations. The yields of primary hot fragments are experimentally reconstructed for multifragmentation events in the reaction system $^{64}$Zn + $^{112}$Sn at 40 MeV/nucleon. Using the reconstructed hot isotope yields and an improved method, based on the modified Fisher model, symmetry energy values relative to the apparent temperature, $a_{sym}/T$, are extracted. The extracted values are compared with those of the AMD simulations, extracted in the same way as that for the experiment, with the Gogny interaction with three different density-dependent symmetry energy terms. $a_{sym}/T$ values change according to the density-dependent symmetry energy terms used. Using this relation, the density of the fragmenting system is extracted first. Then symmetry energy and apparent temperature are determined in a self consistent manner in the AMD model simulations. Comparing the calculated $a_{sym}/T$ values and those of the experimental values from the reconstructed yields, $ρ/ρ_{0} = 0.65 \pm 0.02 $, $a_{sym} = 23.1 \pm 0.6$ MeV and $T= 5.0 \pm 0.4$ MeV are evaluated for the fragmenting system experimentally observed in the reaction studied.

description: Background: Retrospective evaluation of the safety and efficacy of the retrieval of misplaced central venous catheters (CVCs) in subclavian arteries using the femoral closure device Angio-Seal™. Methods: The clinical data of five patients (female, n = 2; mean age, 55.0 years ± 11.9) in whom a misplaced CVC within a subclavian artery was removed followed by closure of the vessel entry site with 8-French (F) Angio-Seal™ was analyzed. Results: In 4/5 patients (80%; CVC diameter, 7-8F) the procedure was technically successful without complications. In 1/5 patients (20%; CVC diameter, 11.5F) the procedure failed and an additional covered stent was placed for successful closure of the vessel entry site. There were no complications associated with the Angio-Seal™ or stent implantation during follow-up. Conclusion: Retrieval of a misplaced CVC within a subclavian artery using the percutaneous closure device Angio-Seal™ is quite safe and effective; however, caution is required if there is a mismatch in the diameter of the Angio-Seal™ and CVC. In the case of procedure failure, successful closure of the vessel entry site can be achieved by covered stent placement.

description: The close link between socioeconomic status (SES) and health can already be observed in childhood and adolescence. Although the vast majority of children and adolescents grow up healthily in Germany, social inequalities in health exist. The results of the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2) demonstrate that children and adolescents with a low SES have a poorer level of general health and face health constraints more frequently than their peers with a higher SES. Social inequalities in mental health are significantly more profound than in the 12-month prevalence of bronchial asthma and allergic rhinitis. The odds of being affected by mental health problems or attention-deficit/hyperactivity disorder (ADHD) were 2.8 to 4.4 times higher for children and adolescents with a low SES compared to their peers with a high SES. Therefore, in order to enable all children and adolescents to grow up healthily, health promotion and disease prevention measures need to be put in place early in a child’s life and need to be tailored to the needs of particular target groups.
Genetic and biochemical characterization of ISP6, a small mitochondrial outer membrane protein associated with the protein translocation complex.

description: To search genetically for additional components of the protein translocation apparatus of mitochondria, we have used low fidelity PCR mutagenesis to generate temperature-sensitive mutants in the outer membrane translocation pore component ISP42. A high copy number suppressor of temperature-sensitive isp42 has been isolated and sequenced. This novel gene, denoted ISP6, encodes a 61 amino acid integral membrane protein of the mitochondrial outer membrane, which is oriented with its amino-terminus facing the cytosol. Disruption of the ISP6 gene is without apparent effect in wild type yeast cells, but is lethal in temperature-sensitive isp42 mutants. Immunoprecipitation of the gene product, ISP42p, from mitochondria solubilized under mild conditions reveals a multi-protein complex containing ISP6p and ISP42p.
