Regulation of apolipoprotein E secretion, lipidation and recycling in the central nervous system
Creators: name: Fan, Jianjia
Publisher: name: University of British Columbia
Year: 2014

description: Lipid transport in the brain is coordinated by glia-derived lipoproteins that contain apolipoprotein E (apoE) as their primary protein. ApoE plays an important role in the pathogenesis of neurodegenerative diseases such as Alzheimer's disease (AD). ATP-binding cassette transporter A1 (ABCA1) effluxes cholesterol and phospholipids to apolipoprotein acceptors including apoE. ABCA1 is a key regulator of apoE levels and lipidation in the brain and deficiency of ABCA1 increases amyloid burden in AD mouse models. Translating these findings to potential therapies for AD will require a more thorough understanding of the biochemical nature of nascent apoE particles generated from glia and of lipoprotein remodeling in the CNS in general. In this thesis, I show that apoE is secreted from wild-type primary murine mixed glia as nascent lipoprotein subspecies ranging from 7.5 to 17 nm in diameter. Glia lacking ABCA1 secrete only one species of small particles (~8.1nm), which are poorly lipidated, but can accept lipids to form the full repertoire of wild-type apoE particles. Inhibition of apoE receptor function blocks appearance of the 8.1 nm species, suggesting that this particle may arise through apoE recycling. Selective deletion of the LDL receptor significantly reduces the level of the 8.1 nm particles, suggesting that apoE is preferentially recycled through LDLR. These results suggest that nascent glial apoE lipoproteins are secreted through multiple pathways. Modulating the expression, secretion or function of apoE may provide potential therapeutic approaches to protect the brain from chronic and acute damage. This thesis shows that progesterone and a synthetic progestin, lynestrenol, significantly induce apoE secretion from human CCF-STTG1 astrocytoma cells, whereas estrogens have negligible effects. Intriguingly, lynestrenol also increases expression of ABCA1 in human astrocytoma cells, primary murine glia, and immortalized murine astrocytes that express human apoE3. The progesterone receptor (PR) inhibitor RU486 attenuates the effect of progestins on apoE expression in astrocytoma but has no effect on ABCA1 expression in all glial cell models tested, suggesting that PR may participate in apoE but does not affect ABCA1 regulation. These results suggest that selective reproductive steroid hormones have the potential to influence glial lipid homeostasis through LXR-dependent and PR-dependent pathways.

description: For a given finite group $G$ consisting of morphisms and antimorphisms of a free monoid $\mathcal{A}^*$, we study infinite words with language closed under the group $G$. We focus on the notion of $G$-richness which describes words rich in generalized palindromic factors, i.e., in factors $w$ satisfying $Θ(w) = w$ for some antimorphism $Θ\in G$. We give several equivalent descriptions which are generalizations of know characterizations of rich words (in the terms of classical palindromes) and show two examples of $G$-rich words.

description: A MMIC multi-port highly-integrated phase control device, suitable for application in low cost phased-array antennas is presented. The MMIC consists of eight LNAs, eight sets of RF-switches, a phase manifold, eight phase shifter networks for phase control and two 4 to 1 output power combiners. The DC power supply circuitry, the digital control circuitry and the RF sub modules are combined on the same die. The chip is designed in a mixed analog / digital 0.25 µm PHEMT technology. It is shown that the functionality of this chip is equivalent to eight separate 3-bit phase shifters.

description: We present both spin-independent and -dependent parts of a central interquark potential for charmonium states, which is calculated in 2+1 flavor dynamical lattice QCD using the PACS-CS gauge configurations with a lattice cutoff of a^{-1}~2.2 GeV. Our simulations are performed with a relativistic heavy quark action for the charm quark at the lightest pion mass, M_π=156(7) MeV, in a spatial volume of 3fm^3. We observe that the spin-independent charmonium potential obtained from lattice QCD with almost physical quark masses is quite similar to the Conrnell potential used in non-relativistic potential models. The spin-spin potential properly exhibits the short range repulsive interaction, while its r-dependence is different from either a point-like spin-spin potential generated by one-gluon exchange or a phenomenological finite-range one adopted in quark potential models.

description: In this paper the design and characterization of a linear C-band single ended resistive SiC-MESFET mixer is presented. The mixer has a minimum conversion loss of 7.8 dB and has a third order intermodulation intercept point of 30.3 dBm. The mixer is designed using a harmonic-balance simula-tion load-pull approach. This design method is especially use-ful for high-level mixers, where small-signal approximations cannot be used.

description: Radiation detectors work as Schottky devices. The Schottky contact of the investigated detectors consists of a Ti/Pt/Au layer on the front-side of a 500?m thick semi-insulating GaAs substrate. The back-side is an alloyed Ge/Au ohmic contact.The structure of these contacts are squares with sides of between 1,5mm and 5mm. In order to seperate the behaviour of the contacts, an independent determination of those parameters of the bulk material which are responsible for a satisfactory functioning of the detector are necessary. We present a theoretical model of the detector which simulates detector properties according to relevant parameters such as the resistivity p, the mobility ? of the charge carriers, the energy level EDD and concentration NDD of the bulk-defects and the leakage-current jL of the device. The aim of this study is to determine these parameters experimentally and compare materials from different suppliers. The relevant parameters are then used for the detector simulation.

description: Spin-orbit coupled semiconductor nanowires with Zeeman splitting in proximity contact with bulk $s$-wave superconductivity have recently been proposed as a promising platform for realizing Majorana fermions. However, in this setup the chemical potential of the nanowire is generally pinned by the Fermi surface of the superconductor. This makes the tuning of the chemical potential by external electrical gates, a crucial requirement for unambiguous detection of Majorana fermions, very challenging in experiments. Here we show that tunable topological superconducting regime supporting Majorana fermions can be realized in semiconductor nanowires using uniaxial stress. For n-type nanowires the uniaxial stress tunes the effective chemical potential, while for p-type systems the effective pairing may also be modified by stress, thus significantly enhancing the topological minigap. We show that the required stress, of the order of 0.1%, is within current experimental reach using conventional piezo crystals.

description: It is shown that a Quantum Isolated Horizon(QIH), as observed by a local observer, is locally unstable as a thermodynamic system. The result is derived in two different ways. Firstly, the specific heat of the QIH is shown to be negative definite through a quantum statistical analysis. Then, it is shown, in the thermal holographic approach, that the canonical partition function of the QIH diverges under Gaussian thermal fluctuations of such energy spectrum, implying local instability of such a QIH as a thermodynamic system.

description: Traditional studies about disease dynamics have focused on global stability issues, due to their epidemiological importance. We study a classical SIR-SI model for arboviruses in two different directions: we begin by describing an alternative proof of previously known global stability results by using only a Lyapunov approach. In the sequel, we take a different view and we argue that vectors and hosts can have very distinctive intrinsic time-scales, and that such distinctiveness extends to the disease dynamics. Under these hypothesis, we show that two asymptotic regimes naturally appear: the fast host dynamics and the fast vector dynamics. The former regime yields, at leading order, a SIR model for the hosts, but with a rational incidence rate. In this case, the vector disappears from the model, and the dynamics is similar to a directly contagious disease. The latter yields a SI model for the vectors, with the hosts disappearing from the model. Numerical results show the performance of the approximation, and a rigorous proof validates the reduced models.

description: We theoretically investigate the deflection-induced coupling of an electron spin to vibrational motion due to spin-orbit coupling in suspended carbon nanotube quantum dots. Our estimates indicate that, with current capabilities, a quantum dot with an odd number of electrons can serve as a realization of the Jaynes-Cummings model of quantum electrodynamics in the strong-coupling regime. A quantized flexural mode of the suspended tube plays the role of the optical mode and we identify two distinct two-level subspaces, at small and large magnetic field, which can be used as qubits in this setup. The strong intrinsic spin-mechanical coupling allows for detection, as well as manipulation of the spin qubit, and may yield enhanced performance of nanotubes in sensing applications.

Phase properties of operator valued measures in phase space

Year: 2012

description: The Wigner Phase Operator (WPO) is identified as an operator valued measure (OVM) and its eigen states are obtained. An operator satisfying the canonical commutation relation with the Wigner phase operator is also constructed and this establishes a Wigner distribution based operator formalism for the Wigner Phase Distribution. The operator satisfying the canonical commutation relation with the Wigner Phase Operator valued measure (WP-OVM) is found to be not the usual number operator. We show a way to overcome the non-positivity problem of the WP-OVM by defining a positive OVM by means of a proper filter function, based on the view that phase measurements are coarse-grained in phase space, leading to the well known Q-distribution. The identification of Q phase operator as a POVM is in good agreement with the earlier observation regarding the relation between operational phase measurement schemes and the Q-distribution. The Q phase POVM can be dilated in the sense of Gelfand-Naimark, to an operational setting of interference at a beam-splitter with another coherent state - this results in a von Neumann projector with well-defined phase.

description: Recently, we proposed a thermodynamically consistent excluded-volume model for the HG fireball and we noticed that our model gives a suitable description for various properties of multiparticle production and their ratios in the entire range of temperatures and baryon densities. The aim in this paper is to obtain the variations of freeze-out volume in a slice of unit rapidity i.e. $dV/dy$ as well as total volume of the fireball with respect to center-of-mass energy $(\sqrt{s_{NN}})$ and confront our model calculations with the corresponding thermal freeze-out volume obtained from the Hanbury-Brown-Twiss (HBT) pion interferometry method. We also test the validity of our model in extracting the total multiplicities as well as the central rapidity densities of various hadrons and comparing them with the recent results. We further calculate the rapidity as well as transverse momentum spectra of various particles produced in different heavy-ion collider experiments in order to examine the role of flow by matching our predictions suitably with the available experimental results. Finally, we extend our analysis for the production of light nuclei, hypernuclei and their antinuclei over a broad energy range from Alternating Gradient Synchrotron (AGS) to Large Hadron Collider (LHC) energies.

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: The effect of a weak three-dimensional (3d) isotropic laser speckle disorder on various thermodynamic properties of a dilute Bose gas is considered at zero temperature. First, we summarize the derivation of the autocorrelation function of laser speckles in 1d and 2d following the seminal work of Goodman. The goal of this discussion is to show that a Gaussian approximation of this function, proposed in some recent papers, is inconsistent with the general background of laser speckle theory. Then we propose a possible experimental realization for an isotropic 3d laser speckle potential and derive its corresponding autocorrelation function. Using a Fourier transform of that function, we calculate both condensate depletion and sound velocity of a Bose-Einstein condensate as disorder ensemble averages of such a weak laser speckle potential within a perturbative solution of the Gross-Pitaevskii equation. By doing so, we reproduce the expression of the normalfluid density obtained earlier within the treatment of Landau. This physically transparent derivation shows that condensate particles, which are scattered by disorder, form a gas of quasiparticles which is responsible for the normalfluid component.

description: We define in an axiomatic fashion a \emph{Coxeter datum} for an arbitrary Coxeter group $W$. This Coxeter datum will specify a pair of reflection representations of $W$ in two vector spaces linked only by a bilinear paring without any integrality and non-degeneracy requirements. These representations are not required to be embeddings of $W$ in the orthogonal group of any vector space, and they give rise to a pair of inter-related root systems generalizing the classical root systems of Coxeter groups. We obtain comparison results between these non-orthogonal root systems and the classical root systems. Further, we study the equivalent of the Tits cone in these non-orthogonal representations, and we show that strong results on the geometry in the equivalent of the Tits cone can be obtained.

The analytical results show that the connectivity distribution converges to the scaling behavior often found in social and engineering systems. To illustrate the approach of the proposed framework we generate network substrates that resemble steady state properties of the empirical citation distributions of (i) publications indexed by the Institute for Scientific Information from 1981 to 1997; (ii) patents granted by the U.S. Patent and Trademark Office from 1975 to 1999; and (iii) opinions written by the Supreme Court and the cases they cite from 1754 to 2002.

description: Three new isolates (1−3) including one new sterol and two new flavonoids together with three known sterols (4−6) were isolated from the leaves of Nicotiana tabacum. Their structures were determined mainly by spectroscopic methods, including extensive 1D and 2D NMR techniques. All compounds were evaluated for their anti-tobacco mosaic virus and cytotoxic activities. The results showed that compounds 2 and 3 exhibited high anti-TMV activity with inhibition rate of 34.2 and 33.4%, respectively, which were roughly equivalent to that of positive control. The cytotoxicities of compounds 1 and 4–6 against five human tumour cell lines were also tested, and tested compounds showed weak inhibitory activities against some tested human tumour cell lines.
Indigenous knowledge, climate change and forest management : the Nisga'a Nation approach
Creators: name: Arias-Bustamante, Jose
Publisher: name: University of British Columbia

description: Climate change is one of the current threats that are impacting the world, and its consequences are greater when it comes to vulnerable communities. Despite its vast areas covered by untouched forest and plenty of natural resources, British Columbia, with a myriad of First Nations and other Indigenous peoples, is not the exception. First Nations culture and knowledge are based on natural resources; therefore, trying to understand what are the major impacts of a changing climate becomes paramount. Through this research, I sought to examine and characterize potential climate changes impacts in the lands covered by the Nisga’a Nation (Northern BC), and how these impacts are affecting traditional forest practices of the Nisga’a people. The method I used to gather the stories of participants in this study was participatory interviews. For the knowledge interpretation and analysis, I integrated individual research stories and thematic coding. I also conducted a community presentation during which the results were presented to the Wilp Wilxo’oskwhl Nisga’a Institute Board of Directors, enabling the findings to be validated. The Nisga’a People are very concerned about the consequences that climate change could have on fish, not only because of the warmer temperatures, but also because of the flooding and the high level of the Nass River. Forests and the river are intimately connected, so any impacts on forests would have implications on the river, and consequently on fish. For instance, flooding and pests pose great risk to forests. Flooding affects the regeneration of forests species, and pests affect growth, even killing important cultural species for the Nisga’a people (e.g. western redcedar). Thus, by improving the forest’s resilience, the conditions that fish are facing during the spawning seasons would be also improved. To improve current conditions, the findings suggest that it is an imperative to revitalize a more traditional Nisga’a-oriented approach to resource management by adopting an integrative approach, where the management is undertaken from a resilience point of view, allowing the Nisga’a forests to return to their past non-degraded status (i.e. before logging started), and thus able to absorb the expected and unexpected impacts deriving from climate change.

description: We study the \textit{quantum} partition function of non-relativistic, ideal gas in a (non-cubical) box falling freely in arbitrary curved spacetime with centre 4-velocity u^a. When perturbed energy eigenvalues are properly taken into account, we find that corrections to various thermodynamic quantities include a very specific, sub-dominant term which is independent of \textit{kinematic} details such as box dimensions and mass of particles. This term is characterized by the dimensionless quantity, Ξ=R_00 Λ^2, where R_00=R_ab u^a u^b and Λ=β\hbar c, and, quite intriguingly, produces Euler relation of homogeneity two between entropy and energy -- a relation familiar from black hole thermodynamics.

description: No abstracts are to be cited without prior reference to the author.This paper describes the EcoSystemData integrated repository of data. This system was developed to improve the integrated data requests covering for example, the study of climate change in relation to large ecosystem dynamics. A major step forward in EcoSystemData is to join physical, chemical and biological measurements into one system. The data can be queried and analysed in ways that would otherwise have been far more difficult for scientists looking across fisheries and sea climate disciplines.

Generation and Eight-port Homodyne Characterization of Time-bin Qubits for Continuous-variable Quantum Information Processing

description: We experimentally generate arbitrary time-bin qubits using continuous-wave light. The advantage unique to our qubit is its compatibility with deterministic continuous-variable quantum information processing. This compatibility comes from its optical coherence with continuous waves, well-defined spatio-temporal mode, and frequency spectrum within the operational bandwidth of the current continuous-variable technology. We also demonstrate an efficient scheme to characterize time-bin qubits via eight-port homodyne measurement. This enables the complete characterization of the qubits as two-mode states, as well as a flexible analysis equivalent to the conventional scheme based on a Mach-Zehnder interferometer and photon-detection.

description: In dieser Arbeit wurde der Weg von Molchherzzellen des Notophthalmus vivridescens nach der Transplantation in regenerierende Hinterbeinstümpfe untersucht. Dafür wurden die Transplantate zu drei bestimmten Zeitpunkten untersucht: einen, 15 und 30 Tage nach Transplantation in Hinterbeinstümpfe und zur Kontrolle in komplette Hinterbeine. Zur Untersuchung wurden histochemische Methoden herangezogen. Die Injektion in die Hinterbeinstümpfe erfolgte einen Tag nach Amputation. Die erste zentrale Aussage war, dass alle transplantierten Zellen überlebten und mittels TUNEL-Assay keine Apoptosen gefunden wurden. Die in regenerierende Hinterbeinstümpfe eingebrachten Molchherzzellen dedifferenzierten, migrierten und proliferierten während die zur Kontrolle in komplette Hinterbeine eingebrachten Zellen dies nicht taten. Dabei bedienen sich die transplantierten Zellen in Hinterbeinstümpfen zumindest teilweise den Mechanismen von normalen Blastemzellen des Notophthalmus vivridescens.
description: This study is made to resarch the way of cardiomyocytes from Notophthalmus vivridescens after transplantation in regenerating newt stumps after amputation. For this project the transplantates were analysed at three dates: one, 15 and 30 days after transplantation in newstumps and for controlling in complete newt legs. The detection was made by immunhistochemical methods. The injektion in newt stumps was one day after amputation. The first main result was the surviving of all seen transplantated cells and no massive apoptosises were found by using TUNEL-assay. Transplantates in newt stumps did dediffentiation, migration and proliferation under influence of blastema cells but transplantated cells in complete newt legs did not. In this way the transplantates in newt stumps take parts of mechanisms of the usually blastema cells.

description: Histone acetylation is a specific type of chromatin modification that serves as a key regulatory mechanism for many cellular processes in mammals. However, little is known about its biological function in invertebrates. Here, we identified 12 members of histone deacetylases (NlHDACs) in the brown planthopper (BPH), Nilaparvata lugens. RNAi-mediated silencing assay showed that NlHdac1, NlHdac3 and NlHdac4 played critical roles in female fertility via regulating ovary maturation or ovipositor development. Silencing of NlHdac1 substantially increased acetylation level of histones H3 and H4 in ovaries, indicating NlHDAC1 is the main histone deacetylase in ovaries of BPH. RNA sequencing (RNA-seq) analysis showed that knockdown of NlHdac1 impaired ovary development via multiple signalling pathways including the TOR pathway. Acoustic recording showed that males with NlHdac1 knockdown failed to make courtship songs, and thus were unacceptable to wild-type females, resulting in unfertilized eggs. Competition mating assay showed that wild-type females overwhelmingly preferred to mate with control males over NlHdac1-knockdown males. These findings improve our understanding of reproductive strategies controlled by HDACs in insects and provide a potential target for pest control.

description: The effect of irradiation with gamma rays, electrons or neutrons on the dc and low frequency ac electrical characteristics of III-V FET devices has been studied in this work. The electrical parameters more sensitive to radiation damage have been identified and their behaviour has been compared among the different device types. Pseudomorphic HEMTs have been found to tolerate radiation exposures better than GaAs MESFETs and AlGaAs/GaAs HEMTs.

Subjects: ING-INF/01 Elettronica

description: Based on the Raytheon model, GaAs E/D HEMT model parameters are measured and their statistical deviations and correlation coefficients are determined. Output current deviations of transistor current sources and DC offset voltages of differential amplifiers, which represent basic limitations of precise data conversion ICs, are characterized using these experimental data and derived equations with seven model parameters. Monte-carlo simulations are carried out on an 8 bit D/A converter and a latched comparator, which were implemented in 0.5 ?m GaAs E/D HEMT technology, and simulated results are shown to be identical to measured accuracies of these two circuits.
