New directions in local urban stream management: pilot experiences with development review processes in the Comox Valley, BC
Creators: name: Crampton, Angela Michelle
Publisher: name: University of British Columbia
Year: 2009

description: The negative contribution of stream habitat loss to fisheries sustainability in BC has been recognized. Thus, the impact of urban development on streams has become a critical aquatic resource issue. Responsibility for protecting streams from urban development impacts is distributed among all levels of government, and different management processes have evolved to address limitations of this fragmented governance structure. Referral processes have been established to allow senior government input into urban development, but are time consuming, inconsistent, and somewhat reactive. Provincial planning processes support more proactive decision making, but are unable to implement urban stream protection. Local processes have only recently been introduced to fill management gaps and better address urban stream issues. The goal of this thesis is to analyze urban stream management processes in BC and evaluate a new pilot initiative as a local mechanism for improving these processes. To achieve this goal, a program evaluation framework is created and used to evaluate a pilot initiative between the Department of Fisheries and Oceans, BC Ministry of Environment, Lands and Parks, and the Regional District of Comox-Strathcona. This initiative was developed to improve the existing system for reviewing aquatic habitat impacts of urban development proposals. Information on the case study was collected from interviews, documents and records, case examples, and observations. Key strengths of the pilot initiative included a committed local government, supportive senior agencies, sharing of information and resources, and opportunities for education. Key weaknesses included limited public involvement, lack of a regulatory framework, and lack of a broader watershed perspective. Based on the case study evaluation, local processes can improve opportunities for urban stream protection. Critical factors for local urban stream management programs include local commitment and support, senior agency involvement, and public involvement. Local programs need to strike a balance between consistent stream protection and regulatory flexibility, and should be part of a larger watershed-based management approach. Results of these local efforts may not be seen over the short term, but initiating local programs to proactively integrate stream protection into urban development can help protect aquatic and fisheries resources over the long term.

description: Our study of the adsorption of oxygen molecules on individual semiconductiong single-walled carbon nanotubes at ambient conditions reveals that the adsorption is physisorption, that the resistance without O2 increases by ~two orders of magnitude as compared to that with O2, and that the sensitive response is due to the pinning of the Fermi level near the top of the valence band of the tube resulting from impurity states of O2 appearing above the valence band.

A projection-based formulation of the Implicit Function Theorem and its application to time-varying manifolds

description: In this paper, we derive a projection-based formulation of the Implicit Function Theorem. We give conditions, when an algebraic, time-parameterized equation G(t,x) = 0 is solvable for components P^c x that are selected by a projection P^c and we derive an implicit function g that specializes P^c x in terms of the complementary components P x, where P = I - P^c. We apply this result to construct a projection-based parametric description of time-varying submanifolds and to generalize the concept of projections to these sets. We illustrate our results by several examples. The results are motivated by the positivity analysis of differential-algebraic equations (DAEs). These are implicit systems F(t,x,\dot x)=0 whose solutions x are supposed to remain componentwise nonnegative whenever the initial value is nonnegative. To entangle the differential and algebraic components in F(t,x,\dot x)=0 without changing the coordinate system, we pursue the presented projection-based solution of implicit algebraic equations.

DICKINSARTELLA FAUNA FROM THE SAIWAN FORMATION (OMAN): A BIVALVE FAUNA TESTIFYING TO THE LATE SAKMARIAN (EARLY PERMIAN) CLIMATIC AMELIORATION ALONG THE NORTH-EASTERN GONDWANAN FRINGE.
Creators: name: LARGHI, CRISTIANO
Publisher: name: Università degli Studi di Milano
Year: 2005

description: The transitional faunas of the Permian Huqf succession of Oman make it one of the key-sections for the intercalibration of Early to Middle Permian biostratigraphical scales. The abundance of fossils improved the knowledge of some marine faunas which populated the North-Eastern Gondwanan fringe during times of climatic changes in the Permian. A Sterlitamakian (upper Sakmarian, Lower Permian) bivalve fauna from the Saiwan Formation in the Huqf area, informally named "Dickinsartella Fauna", is described in the present paper. The specimens examined were collected from the "Pachycyrtella Bed" (Auctorum), the basal bed of the Formation in its type locality. The Dickinsartella Fauna can be identified for the presence of the new genus Dickinsartella, which dominates the bivalve thanatocoenosis with D. pistacina sp. n. (type species). The bivalve fauna from the Pachycyrtella Bed includes the new species Stutchburia sangallii and Promytilus  mazzolenii, and also Astartella obliqua Dickins, 1963, Nuculopsis cf. bangarraensis Dickins, 1963, ?Oriocrassatella sp., and indeterminable aviculopectinids. This fauna shows a low taxonomic diversity. Nevertheless, some species are represented by a high number of generally well-preserved specimens, i.e. some specimens of S. sangallii sp. n. and A. obliqua show part of the ligament.  The good preservation of the shells permitted the microstructural analysis of D. pistacina sp. n. and S. sangallii sp. n. The microstructure of S. sangallii sp. n. supports the close phylogenetical link between modiomorphids and crassatelloids recognized by some previous authors.
The new genus Dickinsartella includes the more recent species belonging to the important Paleozoic Order Cyrtodontida Scarlato & Starobogatov, 1971. The discovery of Dickinsartella gen. n. and other taxa of the Pachycyrtella Bed, present also in the Sakmarian levels of the Carnarvon and Perth Basins in Western Australia,  indicates a wider distribution of the Dickinsartella Fauna and confirms the correlation between Arabian and Australian series already remarked by previous authors. The "Dickinsartella fauna" is the first bivalve fauna testifying to the climatic amelioration gradually affecting the North-Eastern Gondwanan fringe at the end of the Early Permian glacial events. This pioneer fauna spread out, probably in a cool-temperate climate, on the substrate provided by the mid-Sakmarian (basal Sterlitamakian) transgression, connected with the final stages of the Gondwanan deglaciation and/or with initial sea-floor spreading in the Neotethys. In the present paper some remarks on the autecology of the new species from the "Pachycyrtella bed" are also discussed.

A NEW SPECIMEN OF TANYSTROPHEUS (REPTILIA PROTOROSAURIA) FROM THE MIDDLE TRIASSIC OF SWITZERLAND AND THE ECOLOGY OF THE GENUS
Creators: name: RENESTO, SILVIO
Publisher: name: Università degli Studi di Milano
Year: 2005

description: A new specimen of the protorosaurian diapsid reptile Tanystropheus is described. The specimen was collected at  the Valle Serrata locality (Switzerland) and is of Ladinian (Middle Triassic) age. Its study elucidates some issues regarding the anatomy of Tanystropheus to be addressed, and allow to suggest hypotheses about its mode of life. In particular, the specimen is the first one in which the skin and other soft tissues can be described. In particular, wide patches of black phosphatic material, filled with small carbonate spherules are preserved, as it occurs in corpses lying in stagnant water due to decomposition of consistent amount of proteins. This suggests that a huge mass of flesh was present in the caudal part of the body, shifting posteriorly the center of mass of the animal and helping in balancing the weight of the neck even if raised off horizontal plane and out of water. In addition, no evidence of caudal autotomy is present in Tanystropheus and the structure of the tail and of the limbs are consistent with a shoreline habitat rather than with a fully aquatic mode of life.

description: We improve the earlier restrictions on parameters of the dark matter (DM) in the form of a sterile neutrino. The results were obtained from non-observing the DM decay line in the X-ray spectrum of the Milky Way (using the recent XMM-Newton PN blank sky data). We also present a similar constraint coming from the recent XMM-Newton observation of Ursa Minor -- dark, X-ray quiet dwarf spheroidal galaxy. The new Milky way data improve on (by as much as the order of magnitude at masses ~3.5 keV) existing constraints. Although the observation of Ursa Minor has relatively poor statistics, the constraints are comparable to those recently obtained using observations of the Large Magellanic Cloud or M31. This confirms a recent proposal that dwarf satellites of the MW are very interesting candidates for the DM search and dedicated studies should be made to this purpose.

description: We report on the origin of fragmentation of ultracold atoms observed on a permanent magnetic film atom chip. A novel technique is used to characterize small spatial variations of the magnetic field near the film surface using radio frequency spectroscopy of the trapped atoms. Direct observations indicate the fragmentation is due to a corrugation of the magnetic potential caused by long range inhomogeneity in the film magnetization. A model which takes into account two-dimensional variations of the film magnetization is consistent with the observations.

description: We analyse the results of an Eulerian AMR cosmological simulation in order to quantify the mass growth of galaxy clusters, exploring the differences between dark matter and baryons. We have determined the mass assembly histories (MAHs) of each of the mass components and computed several proxies for the instantaneous mass accretion rate (MAR). The mass growth of both components is clearly dominated by the contribution of major mergers, but high MARs can also occur during smooth accretion periods. We explored the correlations between MARs, merger events and clusters' environments, finding the mean densities in $1 \leq r/R_{200m} \leq 1.5$ to correlate strongly with $Γ_{200m}$ in massive clusters which undergo major mergers through their MAH. From the study of the dark matter velocity profiles, we find a strong anticorrelation between the MAR proxies $Γ_{200m}$ and $α_{200m}$. Last, we present a novel approach to study the angularly-resolved distribution of gas accretion flows in simulations, which allows to extract and interpret the main contributions to the accretion picture and to assess systematic differences between the thermodynamical properties of each of these contributions using multipolar analysis. We have preliminarily applied the method to the best numerically-resolved cluster in our simulation. Amongst the most remarkable results, we find that the gas infalling through the cosmic filaments has systematically lower entropy compared to the isotropic component, but we do not find a clear distinction in temperature.

description: In the present work, we investigate the hidden-strangeness production process in the $S=+1$ channel via $K^+p\to K^+ϕ\,p$, focussing on the exotic \textit{pentaquark} molecular $K^*Σ$ bound state, assigned by $P^+_s(2071,3/2^-)$. For this purpose, we employ the effective Lagrangian approach in the tree-level Born approximation. Using the experimental and theoretical inputs for the exotic state and for the ground-state hadron interactions, the numerical results show a small but obvious peak structure from $P^+_s$ with the signal-to-background ratio $\approx1.7\,\%$, and it is enhanced in the backward-scattering region of the outgoing $K^+$ in the center-of-mass frame. We also find that the contribution from the $K^*(1680,1^-)$ meson plays an important role to reproduce the data. The proton-spin polarizations are taken into account to find a way to reduce the background. The effects of the possible $27$-plet pentaquark $Θ^{++}_{27}$ is discussed as well.

THE LATE TRIASSIC ARCHOSAUROMORPH TRILOPHOSAURUS  AS AN ARBOREAL CLIMBER
Creators: name: A. SPIELMANN, JUSTIN

Publisher: name: Università degli Studi di Milano

description: Two species of the unusual archosauromorph Trilophosaurus, T. buettneri Case and T. jacobsi Murry, are known from diverse localities in the Upper Triassic Chinle Group in the southwestern USA. Both species likely occupied similar ecological niches, based on morphological similarities in the postcrania, which are essentially identical. Trilophosaurus occurrences in the Chinle Group are relatively rare, but individual sites are exceptionally rich, suggesting that Trilophosaurus lived in a different paleoenvironment than more typical Chinle vertebrates, which lived in or near streams (phytosaurs, metoposaurs) or on floodplains (aetosaurs, rauisuchians, and dinosaurs). Two potential interpretations are that Trilophosaurus was either an arboreal climber or a fossorial digger. However, the gross skeletal features of Trilophosaurus are not compatible with a fossorial mode of life: the limbs are too long and gracile, proximal limb elements are longer than distal ones, and the claws are laterally compressed, not transversely broadened. The intermittent study of Trilophosaurus has caused the theory of it being arboreal, originally proposed by Gregory, to receive little mention in subsequent studies. We reexamined the functional morphology of Trilophosaurus using a qualitative functional morphological analysis of the skeleton, a quantitative examination of claw curvature, and a quantitative examination of manus/trunk and pes/trunk ratios. Claw morphology of Trilophosaurus shows similarities to the arboreal drepanosaurs Drepanosaurus and Megalancosaurus. Our analysis provides ample evidence to suggest that Trilophosaurus was arboreal.

Impedance boundary conditions for acoustic time harmonic wave propagation in viscous gases

description: We present Helmholtz or Helmholtz like equations for the approximation of the time-harmonic wave propagation in gases with small viscosity, which are completed with local boundary conditions on rigid walls. We derived approximative models based on the method of multiple scales for the pressure and the velocity separately, both up to order 2. Approximations to the pressure are described by the Helmholtz equations with impedance boundary conditions, which relate its normal derivative to the pressure itself. The boundary conditions from first order on are of Wentzell type and include a second tangential derivative of the pressure proportional to the square root of the viscosity, and take thereby absorption inside the viscosity boundary layer of the underlying velocity into account. The velocity approximations are described by Helmholtz like equations for the velocity, where the Laplace operator is replaced by $\nabla \Div$, and the local boundary conditions relate the normal velocity component to its divergence. The velocity approximations are for the so-called far field and do not exhibit a boundary layer. Including a boundary corrector, the so called near field, the velocity approximation is accurate even up to the domain boundary. The boundary conditions are stable and asymptotically exact, which is justified by a complete mathematical analysis. The results of some numerical experiments are presented to illustrate the theoretical foundation.

description: Upper Triassic brachiopods from 2 localities in the reef Dachstein Limestone of the SE Hochschwab massif in Styria, Austria are systematically described and illustrated. About 900 variably preserved specimens belong to 28 species, representing thus the most diverse brachiopod fauna known from the North Alpine Dachstein Limestone. This indicates that brachiopods were common inhabitants of reef habitats during the Alpine Norian. Oxycolpella, Sinucosta and Aulacothyropsis are dominant. Seven brachiopod species are known from the Kössen Formation (Rhaetian). Adygella biplicata (Dagys) and Ladinian Hungarispira loretzi (Bittner) are the newcomers in the Nordalpine Dachstein Limestone. In addition to brachiopods, only some fragments of bivalves were found. Conodonts of the species Epigondolella triangularis (Budurov 1972) indicate the Early Norian age.

description: In this work, at first we present a model of studying astrophysical flows of binary systems and microquasars based on the laws of relativistic magnetohydrodynamics. Then, by solving the time independent transfer equation, we estimate the primary and secondary particle distributions within the hadronic astrophysical jets as well as the emissivities of high energy neutrinos and $γ$-rays. One of our main goals is, by taking into consideration the various energy-losses of particles into the hadronic jets, to determine through the transport equation the respective particle distributions focusing on relativistic hadronic jets of binary systems. As a concrete example we examine the extragalactic binary system LMC X-1 located in the Large Magellanic Cloud, a satellite galaxy of our Milky Way Galaxy.

THE MID- JURASSIC MARINE TRANSGRESSION IN EAST AFRICA: NEW DATA ON THE DEPOSITIONAL ENVIRONMENT AND AGE OF THE LOWER KAMBE FORMATION (AALENIAN TO BAJOCIAN) IN THE MOMBASA AREA (S.E. KENYA)

description: The Lower Kambe Formation crops out from Mombasa towards the northeast, along the coastal area of Kenya; it was deposited during the first phases of the Middle Jurassic marine transgression. The lithology of the Lower Kambe Fm. varies passing from the southern areas towards the north: near Mombasa, this formation consists of an alternance of calcareous and marly intervals; the marly levels become thinner and tend to disappear towards the north, where the succession becomes entirely calcareous and shows features of a carbonate platform. According to field observations, in the Mwachi River area near Mombasa, four lithological units crop out, that we consider as informal members, namely from bottom : (a) Calcarenitic member (Cam), well bedded calcarenites and some conglomerates; (b) Lower Shaly member (LSm), marly shales with marly limestone beds; (c) Conglomeratic member (Cgm), alternance of calcarenitic beds and levels of conglomerates; (d) Upper Shaly member (USm), marly shales and siltstones with thin beds of calcilutites and quartz sandstones. The sedimentological features of the Cam point to a shoreline environment, possibly shoreface; those of the LSm to a mid/outer ramp; the onset of tectonically active slopes is evidenced by the occurrence of gravity flow structures in the fine-grained sediments. At the top of LSm a marked shallowing of the deposition environment occurred. The Cgm was deposited on a inner ramp, where polymictic coarse deposits (arenaceous, shaly and carbonate clasts) indicating a strong erosion of the coastal areas, were intercalated to the wave-winnowed calcarenites; also the calcarenitic upper portion of the Cgm was deposited on an high energy inner ramp depositional environment. Upwards, a deepening occurred, as the fine sediments of the USm point to a mid/outer ramp. The age of the Lower Kambe Formation has been determined by several Authors on the basis of ammonites; in this work calcareous nannofossils stratigraphy is provided. The age given by ammonites is Bajocian; the calcareous nannofossil assemblage, found in various localities along the Mwachi River, indicates an Aalenian - Bajocian p.p. age. The discrepancy is possibly due to a complex geological situation (faults ?) in the localities with ammonites.

description: This paper considers the problem of computing the state reachable points, from the origin, of a linear constant coefficient descriptor system. A numerical algorithm is proposed that can be implemented to characterize the reachable set in a numerically stable way. The original descriptor system is transformed into strangeness-free system within the behavioral framework followed by a projection that separates the system into its differential and algebraic parts. It is shown that the computation of the image space of two matrices, associated with the projected system, is enough to compute the reachable set (from the origin). Moreover, a characterization is presented of all the inputs by which one can reach to any arbitrary points in the reachable set. The effectiveness of the proposed approach is demonstrated through numerical examples.

description: A new species of irregular echinoid, Ovulaster protodecimae, is described from the Danian Scaglia Rossa Formation outcropping in the Venetian Prealps (Southern Alps, northeastern Italy). The new species, belonging to the order Spatangoida, is very distinctive because of its inflated, almost triangular test, the high-positioned periproct and the plate arrangement on the oral face. This is the first report of the genus Ovulaster in the Danian of Italy and the first description of an echinoid from the Early Palaeocene of Italy. One test has an epifauna of the sessile verrucid barnacle Verruca sp. cf. V. prisca Bosquet, 1854, attached on all except the oral surface.

Para estudar estas representações, realizámos uma entrevista semiestruturada nas primeiras 72 horas após o nascimento dos bebés a 150 mães portuguesas de bebés prematuríssimos (Idade Gestacional: IG <32 semanas), prematuros (IG 32-36 semanas) ou de termo (IG >37 semanas). A entrevista incluía os seguintes temas: gravidez, parto, nascimento antecipado, maternidade, temperamento e futuro desenvolvimento do bebé. Os três grupos de mães relatam experiências de gravidez, parto e pós-parto distintas. As mães dos bebés termo respondem com mais frequência que os seus bebés são calmos e que vai ser bom cuidar deles. Enquanto, as mães dos prematuros, foram as que mais responderam que planearam e aceitaram a gravidez, e não que esperam dificuldades no futuro. Todavia, receberam com medo a notícia do nascimento prematuro do seu filho e relatam ter sentido medo e/ou culpa quando se afastaram do seu bebé internado nos cuidados intensivos. Por fim, as mães dos prematuríssimos apresentam maior percentagem de respostas nas categorias não me senti apoiada na gravidez, senti pânico e choque quando soube que o seu filho ia nascer tão precocemente e não consigo ou não quero pensar sobre o futuro. Importa oferecer respostas de apoio psicológico e aconselhamento diferenciadas às famílias atendendo à idade gestacional do bebé e a fatores de risco neonatal.

description: The present work deals with the resolution of the Poisson equation in a bounded domain made of a thin and periodic layer of finite length placed into a homogeneous medium. We provide and justify a high order asymptotic expansion which takes into account the boundary layer effect occurring in the vicinity of the periodic layer as well as the corner singularities appearing in the neighborhood of the extremities of the layer. Our approach combines the method of matched asymptotic expansions and the method of periodic surface homogenization, and a complete justification is included in the paper or its appendix.

description: Quantum key distribution (QKD) can generate secure key bits between remote users with quantum mechanics. However, the gap between the theoretical model and practical realizations gives eavesdroppers opportunities to intercept secret key. The most insidious attacks, known as quantum hacking, are the ones with no significant discrepancy of the measurement results using side-channel loopholes of QKD systems. Depicting full-time-scale characteristics of the quantum signals, the quantum channel, and the QKD system can provide legitimate users extra capabilities to defeat malicious attacks. For the first time, we propose the method exploring temporal ghost imaging (TGI) scheme to perceive quantum hacking with temporal fingerprints and experimentally verify its validity. The scheme presents a common approach to promote QKD's practical security from a new perspective of signals and systems.

description: The Penrose process in the vicinity of an extremal Banãdos-Teitelboim-Zanelli(BTZ) black hole is studied. Due to the existence of negative cosmological constant, only massless particles could escape to infinity. Hence we analyse the Penrose process by one massless particle collides with another massive particle near the horizon of BTZ black holes. Calculations of the maximum energy extraction efficiency of this process is carried out for both spinless and spinning particles. Our results show that the spinning particle have a higher energy extraction efficiency than the spinless particle. Moreover, our calculation also indicates that the maximum energy extraction efficiency is independent of the value of the cosmological constant of BTZ black holes.

Jacques Derrida e il non fenomenologico
Creators: name: Resta, Caterina
Publisher: name: Bollettino Filosofico
Year: 2018

description: From its very first steps, Derrida’s thought engages a close confrontation with Husserlian phenomenology in order to take distance from it. My thesis is that, in spite of a claimed “fidelity” to phenomenological method, Derridian thought of différance has as its own preferential critical target phenomenology itself, intended as thought of the living present, of presence and of evidence. Starting from this thesis, deconstruction may be read first of all as deconstruction of phenomenology. It shows the irreducible character of the “non-phenomenological,” which every phenomenology tries to conceal as its own limit, as testified by Derrida’s analysis of gift and secret. These belong to the thought of sur-vival, which reveals death – the non-phenomenological par excellence – in the heart of life.

description: Quantum thermodynamics has emerged as a separate sub-discipline, revising the concepts and laws of thermodynamics, at the quantum scale. In particular, there has been a disruptive shift in the way thermometry, and thermometers are perceived and designed. Currently, we face two major challenges in quantum thermometry. First, all of the existing optimally precise temperature probes are local, meaning their operation is optimal only for a narrow range of temperatures. Second, aforesaid optimal local probes mandate complex energy spectrum with immense degeneracy, rendering them impractical. Here, we address these challenges by formalizing the notion of global thermometry leading to the development of optimal temperature sensors over a wide range of temperatures. We observe the emergence of different phases for such optimal probes as the temperature interval is increased. In addition, we show how the best approximation of optimal global probes can be realized in spin chains, implementable in ion traps and quantum dots.

description: Automatic MRI brain tumor segmentation is of vital importance for the disease diagnosis, monitoring, and treatment planning. In this paper, we propose a two-stage encoder-decoder based model for brain tumor subregional segmentation. Variational autoencoder regularization is utilized in both stages to prevent the overfitting issue. The second-stage network adopts attention gates and is trained additionally using an expanded dataset formed by the first-stage outputs. On the BraTS 2020 validation dataset, the proposed method achieves the mean Dice score of 0.9041, 0.8350, and 0.7958, and Hausdorff distance (95%) of 4.953, 6.299, and 23.608 for the whole tumor, tumor core, and enhancing tumor, respectively. The corresponding results on the BraTS 2020 testing dataset are 0.8729, 0.8357, and 0.8205 for Dice score, and 11.4288, 19.9690, and 15.6711 for Hausdorff distance.

description: We report near-infrared (primarily H-band) adaptive optics (AO) imaging with the Gemini-N and Subaru Telescopes, of a representative sample of 32 nearby (z<0.3) QSOs selected from the Palomar-Green (PG) Bright Quasar Survey (BQS), in order to investigate the properties of the host galaxies. 2D modeling and visual inspection of the images shows that ~36% of the hosts are ellipticals, \~39% contain a prominent disk component, and ~25% are of undetermined type. 30% show obvious signs of disturbance. The mean M_H(host) = -24.82 (2.1L_H*), with a range -23.5 to -26.5 (~0.63 to 10 L_H*). At 2 L_H* most are ellipticals. "Disturbed" hosts are found at all M_H(host), while "strongly disturbed" hosts appear to favor the more luminous hosts. Hosts with prominent disks have less luminous QSOs, while the most luminous QSOs are almost exclusively in ellipticals or in mergers (which presumably shortly will be ellipticals). At z<0.13, where our sample is complete at B-band, we find no clear correlation between M_B(QSO) and M_H(host). However, at z>0.15, the more luminous QSOs (M_B7L_H*), most of which are ellipticals. Finally, we find a strong correlation between the "infrared-excess", L_IR/L_BB, of QSOs with host type and degree of disturbance. Disturbed and strongly disturbed hosts and hosts with dominant disks have L_IR/L_BB twice that of non-disturbed and elliptical hosts, respectively. QSOs with "disturbed" and "strongly-disturbed" hosts are also found to have morphologies and mid/far-infrared colors that are similar to what is found for "warm" ultraluminous infrared galaxies, providing further evidence for a possible evolutionary connection between both classes of objects.

Ligand induced changes in amino acid accessibility of P-Glycoprotein
Creators: name: Do, Thuan H.
Publisher: name: University of British Columbia
Year: 2009

description: P-Glycoprotein (Pgp) is a 170 kDa plasma membrane protein belonging to the ATP-Binding Cassette (ABC) superfamily. The expression of this protein in tumor cells leads to the emergence of a multidrug resistance phenotype (MDR) which is thought to be responsible for the failure of chemotherapy in some forms of cancer. Pgp is an ATP-dependent drug efflux pump, using the energy of ATP hydrolysis to mediate drug transport. The mechanism of substrate recognition and transport, however, is poorly understood. There is strong evidence that Pgp proceeds through various structural changes as it goes through its catalytic cycle. In the present study, non-selective fluorescent labeling with a residue-specific fluorescent modification agent was used to locate regions on Pgp that undergo conformational changes with substrate binding. A lysine-specific modification agent, DEACSE, was used to label Pgp and fluorescent peptide maps were generated by protease cleavage. The labeling profiles of Pgp in the presence of various substrates were compared to pinpoint regions that exhibited ligand-dependent changes in accessibility to DEACSE. Several cleavage products show significant changes in fluorescence intensity with different substrates. Selected peptides were identified by MALDI-TOF mass analysis and N-terminal peptide sequencing. Two peptides with reduced labeling upon nucleotide binding were localized respectively to the amino (525GAQLSGGQKQR) and carboxyl (1170GTQLSGGQKQR) Walker C signature motif within the nucleotide binding domains of Pgp (modified lysine residue in bold and underlined). On the other hand, two peptides with increased labeling were observed in the predicted second cytoplasmic loop. Peptide 260TVIAFGGQKK appears to be the most dynamic and experienced a significant increase in fluorescence while the second peptide, 284LGIKK, encountered a more modest increase. These findings indicate that the non-selective fluorescent modification technique developed in this study can be used to map in greater detail areas of conformational changes in Pgp. This technique should be applicable also to other protein systems, including a number of ABC proteins. Initial results from this study are consistent with the proposal by others that the Walker C signature sequence may be involved in coupling ATP binding and/or hydrolysis to substrate transport. In addition, they show that nucleotide binding can induce significant structural changes within the transmembrane domains located at a distance along the linear sequence of the protein from the nucleotide binding sites. These results provide evidence that supports a mechanism in which energy is transduced to effect a global conformational change associated with transport.
