ANALYSE DES RAPPORTS DU COPÉPODE PARASITE XENOCOELOMA ALLENI (BRUMPT) ET DE SON HÔTE POLYCIRRUS CALIENDRUM CLAPARÈDE

description: A lot of 28 Xenocoeloma alleni (Brumpt) has been histologically studied to point out the relation of this parasite with its host, Polycirrus caliendrum Claparède. The youngest parasites of our collection were in stage 2 as defined by Caullery and Mesnil. We have not been successful in obtaining stage pupa. In Annelida harbouring young parasites, it is possible to observe at the base of the latter a nodule due to reaction which disappears when the parasite is adult. This reaction of the host does not seem to exist in Polycirrus arenivorus. The membrane which covers the body of Xenocoeloma is not, as Caullery and Mesnil thought, the basal of the epithelium of Polycirrus. It is really a tegument formation, characteristic of the parasite, whose outline can be followed, and which on the first hand enters the funnel formed by the axial cavity, and on the other hand, in the atrial cavity of the parasite, whereas the epithelium of Annelida does not penetrate in these cavities. However, the tegument of Xeno- coeloma seems to have undergone important modifications owing to parasitic adaptation: it is not possible to discern between the cuticle and epicuticle; growth takes place without moult. The epithelium devoid of basal can only be clearly observed in the axial cavity and in the atrial cavity; on the rest of the body, an epithelial nucleus can be seen in places.
As a point of view of the permanent effects of parasitism on the host, it seems to bring a restriction of the fecundity of the females.
The only nutrition organs of the parasite are constituted of rose shaped glands and meandering glands which terminate at the bottom of the funnel formed by the axial cavity. The rose shaped glands secrete a mucoid substance in the axial cavity. The aspect of the meandering organ reminds that of the intestinal villosities.

description: Within the background-field framework we present a path integral derivation of the splitting Ward identity for the one-particle irreducible effective action in the presence of an infrared regulator, and make connection with earlier works on the subject. The approach is general in the sense that it does not rely on how the splitting is performed. This identity is then used to address the problem of background dependence of the effective action at an arbitrary energy scale. We next introduce the modified master equation and emphasize its role in constraining the effective action. Finally, application to general gauge theories within the geometric approach is discussed.

The obturaculum of Riftia pachyptila (Annelida, Vestimentifera): Ultrastructure and function of the obturacular muscles and extracellular matrix

Year: 2001

description: The Vestimentifera have in their branchial plume a centralized structure, the obturaculum, supporting the
 respiratory lamellae and enabling the worm to close its tube. We have studied its structure in Riftia pachyptila, focusing on
 the relations between its main parts: epidermis, muscles and extracellular matrix (ECM). The epidermis is supported by a
 thick collagenous layer, through which cell processes extend into the ECM. These processes contain rough endoplasmic
 reticulum (RER), and they often surround the subepidermal obturacular muscles. Each muscle is a bundle of 10-35 smooth
 muscle fibres, embedded in the ECM. The apical part, made of thin (and probably juvenile) muscle fibres, is present in each
 muscle. The thick myofilaments range from 20 to 150 nm in diameter, and show a cross-banded periodicity of 12-14 nm
 similar to paramyosin. Each thick myofilament is surrounded by 12 to 18 thin myofilaments about 5-7 nm in diameter. The
 nucleus is located laterally in the fibres, and generally surrounded by swollen cisterns of RER. The large obturacular matrix
 contains collagen fibrils, with a diameter of 30 nm and a striation every 64 nm. It also contains proteoglycans and cells, in
 groups of two or more, surrounded by a thin basal lamina, often lined with bundles of collagen fibrils. These cells often
 contain swollen cisterns of RER, suggesting they are equivalent to fibroblasts synthesizing the surrounding collagen fibrils.
 We discuss whether the obturaculum presents the features of a primitive cartilage, or those of a "catch" type connective
 tissue.

description: Quantitative measurement of the number of Cse4, CBF3, and Ndc80 proteins at kinetochores reveals a 2.5–3-fold increased copy number relative to prior estimates.Cse4 is the budding yeast homologue of CENP-A, a modified histone H3 that specifies the base of kinetochores in all eukaryotes. Budding yeast is unique in having only one kinetochore microtubule attachment site per centromere. The centromere is specified by CEN DNA, a sequence-specific binding complex (CBF3), and a Cse4-containing nucleosome. Here we compare the ratio of kinetochore proximal Cse4-GFP fluorescence at anaphase to several standards including purified EGFP molecules in vitro to generate a calibration curve for the copy number of GFP-fusion proteins. Our results yield a mean of ∼5 Cse4s, ∼3 inner kinetochore CBF3 complexes, and ∼20 outer kinetochore Ndc80 complexes. Our calibrated measurements increase 2.5–3-fold protein copy numbers at eukaryotic kinetochores based on previous ratio measurements assuming two Cse4s per budding yeast kinetochore. All approximately five Cse4s may be associated with the CEN nucleosome, but we show that a mean of three Cse4s could be located within flanking nucleosomes at random sites that differ between chromosomes.

description: By exploiting the relatively long lifetime of the tau lepton, we propose several novel methods for searching for new physics at an electron-positron collider. We consider processes that involve final states consisting of a tau lepton pair plus two missing particles. The mass and spin of the new physics particles can be measured in 3-prong tau decays. The tau polarization, which reflects the coupling to new physics, can be measured from the $τ\to πν$ decay channel using the impact parameter distribution of the charged pion. We also discuss the corresponding backgrounds for these measurements, the next-to-leading order (NLO) effects, and the implications of finite detector resolution.

description: This study offers pathways and analysis of how Minnesota (MN) could transition from its current energy system to one that is decarbonized by 80% (from 2005 level) by 2050 [80×50]. The decarbonization would include the entire economy and is assumed to include energy efficiency measures, electrification, and generation changes. The study will model the entire United States (US) portion of the Eastern Interconnection along with electricity trade between the US, Mexico and Canada. The primary purpose of the study is to determine how Minnesota can meet the goals of 80×50 under various scenarios. These scenarios will be evaluated against a baseline scenario that assumes minimal electrification and no additional climate policies beyond those already enacted into law.

description: On the geographic variation of Gobius minutus Pallas. II. - Morphological chromatic and numerical characters.
The present study on the variability of Gobius minutus—a bony fish living in the littoral zone of European coastal waters—is based on a large material from many localities in the whole area of distribution. It shows that the species is very constant in respect of such characters as the disposition of the cutaneous papillae and coloration, and that the intensity of the pigment varies only locally or microgeographically. On the other hand, the species is more variable in respect of length of body and also in growth, the length of the life cycle, the inceptionof sexual maturity, and the proportions between the sexes. Geographical variation has been observed in all these features. The numerical characters also studied—the number of vertebrae and the number of fin rays in the second dorsal fin and the anal fin—are variable and show considerable variation in both the local population and in the distribution area as a whole, where the geographical variation is manifested in dines. In relation to the total variation, the local variation in the fin rays is great, but less great in the number of vertebrae.
Correlation has been demonstrated between the dines for the numerical,
metric and biological characters of Gobius minutus and the ecological dines in the temperate zone. Similar correlation is found between the variation in the local population and the local environmental situation. This correlation implies that the geographical variation is mainly a consequence of the influence of the environment. The deviating means in the numerical characters typical of the peripheral populations in comparison with those found in the central regions are therefore probably not due to the occurrence of different races, but to the extreme ecological factors prevailing at the limits of the distribution area of the species. Thus, it seems as if neither the variability of the numerical features nor

description: Set7 associates with the MyoD transcription factor to enhance expression of genes required for muscle differentiation.The molecular events that modulate chromatin structure during skeletal muscle differentiation are still poorly understood. We report in this paper that expression of the H3-K4 histone methyltransferase Set7 is increased when myoblasts differentiate into myotubes and is required for skeletal muscle development, expression of muscle contractile proteins, and myofibril assembly. Knockdown of Set7 or expression of a dominant-negative Set7 mutant impairs skeletal muscle differentiation, accompanied by a decrease in levels of histone monomethylation (H3-K4me1). Set7 directly interacts with MyoD to enhance expression of muscle differentiation genes. Expression of myocyte enhancer factor 2 and genes encoding contractile proteins is decreased in Set7 knockdown myocytes. Furthermore, we demonstrate that Set7 also activates muscle gene expression by precluding Suv39h1-mediated H3-K9 methylation on the promoters of myogenic differentiation genes. Together, our experiments define a biological function for Set7 in muscle differentiation and provide a molecular mechanism by which Set7 modulates myogenic transcription factors during muscle differentiation.

description: The activity of metabolic enzymes is controlled by three principle levels: the amount of enzyme, the catalytic activity, and the accessibility of substrates. Reversible lysine acetylation is emerging as a major regulatory mechanism in metabolism that is involved in all three levels of controlling metabolic enzymes and is altered frequently in human diseases. Acetylation rivals other common posttranslational modifications in cell regulation not only in the number of substrates it modifies, but also the variety of regulatory mechanisms it facilitates.

description: The light harvesting complexes (LHC) of brown algae are embedded in plastid membranes. Besides chlorophyll
 a, these LHC bind chlorophyll c and fucoxanthin which are efficient for photosynthetic activity. The polypeptides are
 assembled in vivo into macromolecular complexes with molecular masses ranging from 120 to 700 kDa composed of two
 or several distinct components of 17-22 kDa. The chlorophyll c-fucoxanthin binding proteins are phylogenetically and
 structurally related to Chla/b-LHC protein. Indeed, the protein contains three membrane-spanning helices and possesses the
 conserved residues identified in green plants as stabilizing the tertiary structures or binding Chla molecules. However, the
 localization of Chlc and xanthophyll molecules is still unknown. Up to now, it is not clear if in the Chromophyta there are
 antennae transmitting the absorbed energy specifically to one or the other photosystems. The polypeptides are encoded by a
 nuclear multigene family but the total number of genes is not yet established in any species. Recently, the expression of Lhc
 genes has been shown to be regulated by light intensity and under the control of a blue receptor. As perspectives, the
 reconstitution of complexes in vitro could help to understand the binding of pigments to proteins. Cloning and
 characterization of the chlorophyll c fucoxanthin binding protein genes allow molecular biology approaches in the studies
 of the gene expression and also to develop a DNA transformation system for brown algae.

description: A survey of organic derivatives of commercially important red seaweed polysaccharides is presented. The most
 important applications of soluble polysaccharides extracted from seaweeds utilize their ability to modify the properties of
 aqueous solutions. The presence of natural substituents and synthetic derivatives have broadened the area of applicability of
 phycocolloids. The ability  of polysaccharides, such as agarose to form hydrophilic supports of well defined dimensions has
 been exploited for the purification of biological molecules. By appropiate modification of the polysaccharide matrices,
 derivatives useful  in the field of medicine, biology and, biotechnology have been developed. Selective chemical
 modifications may facilitate the preparation of derivatives and conjugates with novel applications. Treatment of
 polysaccharides with bromine and periodate may introduce ketone or aldehyde functions, respectively. Neutral
 polysaccharides, such as agarose and xylan, were oxidized with aqueous bromine and then coupled with amines to give
 conjugates with potential biological applications. On the other hand, formation of Schiff bases afforded derivatives with
 metal chelating properties. One of the recent seaweed polysaccharide manipulation involves conjugates with protein carriers,
 which can be artificial immunogen. Alginic acid, from Lessonia trabeculata and its homoguluronic enriched fraction by
 reaction with caprolactam gave amido derivatives which formed covalent bonding with tetanic toxoid protein. Introduction
 of keto group in alginic acid, followed by selective acetylation gave analogs of Salmonella typhi capsular polysaccharide.
 These analogs can be linked to carrier proteins by reductive amination.

description: During mitosis, cohesin and condensin cross-link pericentromeres of different chromosomes to coordinate centromere attachment sites.The mitotic segregation apparatus composed of microtubules and chromatin functions to faithfully partition a duplicated genome into two daughter cells. Microtubules exert extensional pulling force on sister chromatids toward opposite poles, whereas pericentric chromatin resists with contractile springlike properties. Tension generated from these opposing forces silences the spindle checkpoint to ensure accurate chromosome segregation. It is unknown how the cell senses tension across multiple microtubule attachment sites, considering the stochastic dynamics of microtubule growth and shortening. In budding yeast, there is one microtubule attachment site per chromosome. By labeling several chromosomes, we find that pericentromeres display coordinated motion and stretching in metaphase. The pericentromeres of different chromosomes exhibit physical linkage dependent on centromere function and structural maintenance of chromosomes complexes. Coordinated motion is dependent on condensin and the kinesin motor Cin8, whereas coordinated stretching is dependent on pericentric cohesin and Cin8. Linking of pericentric chromatin through cohesin, condensin, and kinetochore microtubules functions to coordinate dynamics across multiple attachment sites.

description: Many core-collapse supernova progenitors are presumed to be in binary systems. If a star explodes in a binary system, the early supernova light curve can be brightened by the collision of the supernova ejecta with the companion star. The early brightening can be observed when the observer is in the direction of the hole created by the collision. Based on a population synthesis model, we estimate the fractions of core-collapse supernovae in which the light-curve brightening by the collision can be observed. We find that 0.19% of core-collapse supernova light curves can be observed with the collisional brightening. Type Ibc supernova light curves are more likely to be brightened by the collision (0.53%) because of the high fraction of the progenitors being in binary systems and their proximity to the companion stars. Type II and IIb supernova light curves are less affected (~1e-3% and ~1e-2%, respectively). Although the early, slow light-curve declines of some Type IIb and Ibc supernovae are argued to be caused by the collision with the companion star (e.g. SN 2008D), the small expected fraction, as well as the unrealistically small separation required, disfavour the argument. The future transient survey by the Large Synoptic Survey Telescope is expected to detect ~10 Type Ibc supernovae with the early collisional brightening per year, and they will be able to provide information on supernova progenitors in binary systems.

description: A decrease in Arp2/3 levels results in an NF-κB–dependent increase in the expression of several secreted factors, resulting in nonautonomous effects on chemotaxis.Arp2/3-branched actin is critical for cytoskeletal dynamics and cell migration. However, perturbations and diseases affecting this network have phenotypes that cannot be fully explained by cell-autonomous effects. In this paper, we report nonautonomous effects of Arp2/3 depletion. We show that, upon Arp2/3 depletion, the expression of numerous genes encoding secreted factors, including chemokines, growth factors, and matrix metalloproteases, was increased, a signature resembling the senescence-associated secretory phenotype. These factors affected epidermal growth factor chemotaxis in a nonautonomous way, resolving the recent contradictions about the role of Arp2/3 in chemotaxis. We demonstrate that these genes were activated by nuclear factor κB via a CCM2–MEKK3 pathway that has been implicated in hyperosmotic stress signaling. Consistent with this, Arp2/3-depleted cells showed misregulation of volume control and reduced actin in the submembranous cortex. The defects in osmotic signaling in the Arp2/3-depleted cells can be rescued by hypoosmotic treatment. Thus, perturbations of Arp2/3 have nonautonomous effects that should be considered when evaluating experimental manipulations and diseases affecting the Arp2/3-actin cytoskeleton.
Raising the bar: new constraints on the Hubble parameter with cosmic chronometers at z$\sim$2

description: One of the most compelling tasks of modern cosmology is to constrain the expansion history of the Universe, since this measurement can give insights on the nature of dark energy and help to estimate cosmological parameters. In this letter are presented two new measurements of the Hubble parameter H(z) obtained with the cosmic chronometer method up to $z\sim2$. Taking advantage of near-infrared spectroscopy of the few very massive and passive galaxies observed at $z>1.4$ available in literature, the differential evolution of this population is estimated and calibrated with different stellar population synthesis models to constrain H(z), including in the final error budget all possible sources of systematic uncertainties (star formation history, stellar metallicity, model dependencies). This analysis is able to extend significantly the redshift range coverage with respect to present-day constraints, crossing for the first time the limit at $z\sim1.75$. The new H(z) data are used to estimate the gain in accuracy on cosmological parameters with respect to previous measurements in two cosmological models, finding a small but detectable improvement ($\sim$5 %) in particular on $Ω_{M}$ and $w_{0}$. Finally, a simulation of a Euclid-like survey has been performed to forecast the expected improvement with future data. The provided constraints have been obtained just with the cosmic chronometers approach, without any additional data, and the results show the high potentiality of this method to constrain the expansion history of the Universe at these redshifts.

description: Vinculin functions as a molecular clutch that organizes leading edge F-actin, generates traction, and promotes focal adhesion formation and turnover but not adhesion growth.In migrating cells, integrin-based focal adhesions (FAs) assemble in protruding lamellipodia in association with rapid filamentous actin (F-actin) assembly and retrograde flow. How dynamic F-actin is coupled to FA is not known. We analyzed the role of vinculin in integrating F-actin and FA dynamics by vinculin gene disruption in primary fibroblasts. Vinculin slowed F-actin flow in maturing FA to establish a lamellipodium–lamellum border and generate high extracellular matrix (ECM) traction forces. In addition, vinculin promoted nascent FA formation and turnover in lamellipodia and inhibited the frequency and rate of FA maturation. Characterization of a vinculin point mutant that specifically disrupts F-actin binding showed that vinculin–F-actin interaction is critical for these functions. However, FA growth rate correlated with F-actin flow speed independently of vinculin. Thus, vinculin functions as a molecular clutch, organizing leading edge F-actin, generating ECM traction, and promoting FA formation and turnover, but vinculin is dispensible for FA growth.

description: The polar phase of superfluid $^3$He is stable in "nematically ordered" densed aerogel. A rotating vessel with the polar superfluid can be filled either by an array of the single quantum vortices or by an array of the half-quantum vortices. It is shown that the inhomogeneous distribution of the spin part of the order parameter arising in an array of half-quantum vortices in strong enough magnetic field tilted to the average direction of aerogel strands leads to the appearance of a satellite in the NMR signal shifted in the negative direction with respect to the Larmor frequency. The satellite is absent in the case of an array of single quantum vortices what allows to distinguish these two configurations. The polar state in the anisotropic aerogel with lower density transforms at lower temperatures to the axipolar state. The array of half-quantum vortices created in the polar phase keeps its structure under transition to the axipolar state. The temperature dependence of the vortex-satellite NMR frequency is found to be slower below the transition temperature to the axipolar state.

description: Localized plasma membrane expansion during axon branching mediated by Netrin-1 occurs via TRIM9-dependent regulation of SNARE-mediated vesicle fusion.Developmental axon branching dramatically increases synaptic capacity and neuronal surface area. Netrin-1 promotes branching and synaptogenesis, but the mechanism by which Netrin-1 stimulates plasma membrane expansion is unknown. We demonstrate that SNARE-mediated exocytosis is a prerequisite for axon branching and identify the E3 ubiquitin ligase TRIM9 as a critical catalytic link between Netrin-1 and exocytic SNARE machinery in murine cortical neurons. TRIM9 ligase activity promotes SNARE-mediated vesicle fusion and axon branching in a Netrin-dependent manner. We identified a direct interaction between TRIM9 and the Netrin-1 receptor DCC as well as a Netrin-1–sensitive interaction between TRIM9 and the SNARE component SNAP25. The interaction with SNAP25 negatively regulates SNARE-mediated exocytosis and axon branching in the absence of Netrin-1. Deletion of TRIM9 elevated exocytosis in vitro and increased axon branching in vitro and in vivo. Our data provide a novel model for the spatial regulation of axon branching by Netrin-1, in which localized plasma membrane expansion occurs via TRIM9-dependent regulation of SNARE-mediated vesicle fusion.

Single Freeze-Out, Statistics and Pion, Kaon and Proton Production in Central Pb-Pb Collisions at $\sqrt{s_{NN}} = 2.76$ TeV

description: Many data in the high energy physics are, in fact, sample means. It is shown that when this exact meaning of the data is taken into account and the most weakly bound states are removed from the hadron resonance gas, the acceptable fit to the whole spectra of pions, kaons and protons measured at midrapidity in central Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV [Phys.Rev.Lett.109,252301(2012)] is obtained. The invariant distributions are predicted with the help of the single-freeze-out model in the chemical equilibrium framework. Low $p_{T}$ pions and protons are reproduced simultaneously as well as $p/π$ ratio. Additionally, correct predictions extend over lower parts of large $p_{T}$ data. Some more general, possible implications of this approach are pointed out.

description: Elminius modestus has now been found at several places where it wasnot previously known on the French Atlantic Coast. It is present "continuously" in suitable places south to Pyla. There is then a gap-due to the nature of the coast and the marked exposure-until Saint-Jean-de-Luz is reached. The Arcachon
Basin is now densely populated.
Grenzverschiebungen? Formen biographischen Lernens in Biographien binationaler Paare [Einzelbeitrag]

description: Biographien binationaler Paare werden im Hinblick auf (Re-)Konstruktionen von gender und natio-ethno-kultureller Zugehörigkeit analysiert. Die Beziehungen sind biographisch anschlussfähig im Hinblick auf die potentielle Realisierung von Lebensentwürfen die, so die Annahme der Paare, in einer mono-nationalen Beziehung nicht möglich gewesen wären. Im Verlauf der biographischen Entwicklungen zeigen sich daher Verschiebungen und Modifikationen der Differenzkategorien, allerdings nicht zwangsläufig in einem emanzipatorischen Sinne.

description: We investigate signatures of population III (PopIII) stars in the metal-enriched environment of GRBs originating from population II-I (PopII/I) stars by using abundance ratios derived from numerical simulations that follow stellar evolution and chemical enrichment. We find that at $z>10$ more than $10%$ of PopII/I GRBs explode in a medium previously enriched by PopIII stars (we refer to them as GRBII$\rightarrow$III). Although the formation of GRBII$\rightarrow$III is more frequent than that of pristine PopIII GRBs (GRBIIIs), we find that the expected GRBII$\rightarrow$III observed rate is comparable to that of GRBIIIs, due to the usually larger luminosities of these latter. GRBII$\rightarrow$III events take place preferentially in small proto-galaxies with stellar masses $\rm M_\star \sim 10^{4.5} - 10^7\,\rm M_\odot$, star formation rates $\rm SFR \sim 10^{-3}-10^{-1}\,\rm M_\odot/yr$ and metallicities $Z \sim 10^{-4}-10^{-2}\,\rm Z_\odot$. On the other hand, galaxies with $Z < 10^{-2.8}\,\rm Z_\odot$ are dominated by metal enrichment from PopIII stars and should preferentially host GRBII$\rightarrow$III. Hence, measured GRB metal content below this limit could represent a strong evidence of enrichment by pristine stellar populations. We discuss how to discriminate PopIII metal enrichment on the basis of various abundance ratios observable in the spectra of GRBs' afterglows. By employing such analysis, we conclude that the currently known candidates at redshift $z\simeq 6$ -- i.e. GRB 050904 \cite[][]{2006Natur.440..184K} and GRB 130606A \cite[][]{2013arXiv1312.5631C} -- are likely not originated in environments pre-enriched by PopIII stars.

description: In a pressure-temperature (P-T) diagram for synthesizing IrTe2 compounds, the well-studied trigonal (H) phase with the CdI2-type structure is stable at low pressures. The superconducting cubic (C) phase can be synthesized under higher temperatures and pressures. A rhombohedral phase with the crystal structure similar to the C phase can be made at ambient pressure; but the phase contains a high concentration of Ir deficiency. In this paper, we report that a rarely studied monoclinic (M) phase can be stabilized in narrow ranges of pressure and temperature in this P-T diagram. The peculiar crystal structure of the M-IrTe2 eliminates the tendency to form Ir-Ir dimers found in the H phase. The M phase has been fully characterized by structural determination and measurements of electrical resistivity, thermoelectric power, DC magnetization, and specific heat. These physical properties have been compared with those in the H and C phases of Ir1-xTe2. Moreover, magnetic and transport properties and specific heat of the M-IrTe2 can be fully justified by calculations with the density-functional theory presented in this paper.

description: The open source MATLAB application CellGeo is a user-friendly computational platform that allows simultaneous, automated tracking and analysis of dynamic changes in cell shape, including protrusions ranging from filopodia to lamellipodia to growth cones.Cell biologists increasingly rely on computer-aided image analysis, allowing them to collect precise, unbiased quantitative results. However, despite great progress in image processing and computer vision, current computational approaches fail to address many key aspects of cell behavior, including the cell protrusions that guide cell migration and drive morphogenesis. We developed the open source MATLAB application CellGeo, a user-friendly computational platform to allow simultaneous, automated tracking and analysis of dynamic changes in cell shape, including protrusions ranging from filopodia to lamellipodia. Our method maps an arbitrary cell shape onto a tree graph that, unlike traditional skeletonization algorithms, preserves complex boundary features. CellGeo allows rigorous but flexible definition and accurate automated detection and tracking of geometric features of interest. We demonstrate CellGeo’s utility by deriving new insights into (a) the roles of Diaphanous, Enabled, and Capping protein in regulating filopodia and lamellipodia dynamics in Drosophila melanogaster cells and (b) the dynamic properties of growth cones in catecholaminergic a–differentiated neuroblastoma cells.
