title: Pathogenic Mechanisms Underlying Immune Dysregulation Associated To Hypomorphic RAG2 Mutation: Role Of Microbiota At Mucosal Interfaces
Creators: name: Rigoni, Rosita
Publisher: name: The Open University
Year: 2018

description: Hypomorphic mutations in the RAG genes cause a profound immunodeficiency associated with multisystem autoimmune–like manifestations, mediated by oligoclonal self-reactive T and B cells, named Omenn Syndrome (OS). The clinical and immunological spectrum of OS presentation is extremely broad. Commonly, patients present symptoms very similar to graft-versus-host disease (GVHD) as inflammatory reactions particularly involve the environmental interfaces such as the skin and gut, leading to distinctive early onset erythroderma and protracted diarrhea. However, the complete comprehension of the molecular and cellular mechanisms underlying such autoimmune-like manifestations in OS is still puzzling. Furthermore, the role played by environmental triggers in the disease pathogenesis remains largely unknown. In this thesis, we demonstrated that in hypomorphic Rag2R229Q\R229Q mice, the OS murine counterpart, mucosal B cell deficiency alters the composition of the gut microbiota and causes bacterial translocation across the intestinal epithelium. Furthermore, loss of T cell tolerance to the commensal microbiota leads to gut inflammation sustained by Th1 and Th17 cells. Interestingly, we provided evidence that these gut-derived inflammatory cells disseminate in the periphery, infiltrating target organs. Decreasing gut bacterial load in Rag2R229Q\R229Q mice with long-term dosing of antibiotics reverses most of these abnormalities and normalizes serum hyper-IgE, a hallmark of the disease. Similar mechanisms are involved in the development of skin degeneration in mutant mice. Indeed, we found that compromised skin barrier integrity results in altered microbial load and composition, and dysregulated production of T cell recruiting chemokines by stimulated epithelial cells. Importantly, we found that the chronic intestinal inflammation synergistically supports the activation of skin epithelial cells and the recruitment of gut-derived pathogenic T cells at the cutaneous barrier. Overall, this work provided first time evidence that commensals and/or commensal-derived signals might play a substantial role in shaping immune response and autoimmunity at barrier sites and beyond in RAG-associated immune deficiency.

description: Computer-aided early diagnosis of Alzheimer's disease (AD) and its prodromal form mild cognitive impairment (MCI) based on structure Magnetic Resonance Imaging (sMRI) has provided a cost-effective and objective way for early prevention and treatment of disease progression, leading to improved patient care. In this work, we have proposed a novel computer-aided approach for early diagnosis of AD by introducing an explainable 3D Residual Attention Deep Neural Network (3D ResAttNet) for end-to-end learning from sMRI scans. Different from the existing approaches, the novelty of our approach is three-fold: 1) A Residual Self-Attention Deep Neural Network has been proposed to capture local, global and spatial information of MR images to improve diagnostic performance; 2) An explanation method using Gradient-based Localization Class Activation mapping (Grad-CAM) has been introduced to improve the explainable of the proposed method; 3) This work has provided a full end-to-end learning solution for automated disease diagnosis. Our proposed 3D ResAttNet method has been evaluated on a large cohort of subjects from real datasets for two changeling classification tasks (i.e., Alzheimer's disease (AD) vs. Normal cohort (NC) and progressive MCI (pMCI) vs. stable MCI (sMCI)). The experimental results show that the proposed approach has a competitive advantage over the state-of-the-art models in terms of accuracy performance and generalizability. The explainable mechanism in our approach is able to identify and highlight the contribution of the important brain parts (e.g., hippocampus, lateral ventricle and most parts of the cortex) for transparent decisions.

description: The unrestricted Pople-Nesbet approach for real atoms is adapted to quantum dots, the man-made artificial atoms, under applied magnetic field. Gaussian basis sets are used instead of the exact single-particle orbitals in the construction of the appropriated Slater determinants. Both system chemical potential and charging energy are calculated, as also the expected values for total and z-component in spin states. We have verified the validity of the energy shell structure as well as the Hund's rule state population at zero magnetic field. Above given fields, we have observed a violation of the Hund's rule by the suppression of triplets and quartets states at the 1p energy shell, taken as an example. We also compare our present results with those obtained using the LS-coupling scheme for low electronic occupations. We have focused our attention to ground-state properties for GaAs quantum dots populated up to forty electrons.

description: This research delves into a question: what can self-publishing as a practice offer to the Chinese émigré community? As a Chinese émigré who has self-exiled to a Western country, I have struggled with my diasporic identity and grappled with the polarized environment within the Chinese diaspora. Many other newcomers from China have to deal with similar struggles and hardships. Against this backdrop, I explore ways to examine and realize my diasporic identity as well as ways to give care to the Chinese émigré community. Since Max Schumann and AA Bronson established the New York Art Book Fair in 2005, the global art publishing community has established a network of art book fairs, independent publishers and artist communities across the globe. A practice-based design research methodology is integrated in this research through a studio practice in which I create, design, print and distribute zines. The following thesis document takes you through a systems thinking lens and examines self-publishing as a complex system. By understanding and locating existing feedback loops in the system (Meadows, 2008 p. 187), I investigate possible paths to build a community for Chinese émigrés through a self-publishing practice.

Identification and characterization of chromosome instability mutants in the yeast Saccharomyces cerevisiae and implications to human cancer
Creators: name: Yuen, Wing Yee Karen
Publisher: name: University of British Columbia
Year: 2011

description: Chromosome instability (CIN) is a hallmark of cancers and may contribute to tumorigenesis. Many genes involved in maintaining chromosome stability are conserved in eukaryotes, and some are mutated in cancers. The goal of this thesis is to use Saccharomyces cerevisiae as a model to identify and characterize genes important for chromosome maintenance, investigate the relevance of CIN to cancer, and develop a strategy to identify candidate therapeutic target genes for selective killing of cancer cells. To systematically identify genes important for chromosome stability, nonessential gene deletion yeast mutants were examined using 3 complementary CIN assays. The chromosome transmission fidelity assay monitors loss of an artificial chromosome. The bimater assay monitors loss of heterozygosity at the mating type locus in homozygous diploid deletion mutants. The a-like faker assay detects loss of the MATα mating type locus in haploid deletion mutants. 293 CIN mutants were identified, including genes functioning in the chromosome or cell cycle, and genes not clearly implicated in chromosome maintenance, such as MMS22, MMS1, RTT101 and RTT107. Phenotypic, genetic and biochemical analyses of these 4 gene products indicate that they function in double strand break repair. They may form a ubiquitin ligase complex that regulates the level of some proteins, including Mms22p itself, during DNA damage response. Human homologues of 10 yeast CIN genes identified were previously shown to be mutated in cancers, suggesting that other human homologues are candidate cancer genes. 101 human homologues of yeast CIN genes were sequenced in a panel of colorectal cancers, identifying 20 somatic mutations in 8 genes. In particular, 17 mutations were found in 5 genes involved in sister chromatid cohesion. Further functional studies should reveal whether mutations in cohesion genes contribute to CIN in cancers. While CIN mutations may contribute to cancer, CIN cancer cells may become inviable when combined with another non-essential mutation, providing the basis for cancer cell-specific therapy. Mutations in CTF4, CTF18, and DCC1 in yeast cause synthetic lethality when combined with mutations in various CIN genes whose human homologues are mutated in cancers. Such analyses in yeast can propose potential drug targets in human for cancer therapy.

description: In this Letter we show that multiband observations of stellar-mass binary black holes by the next generation of ground-based observatories (3G) and the space-based Laser Interferometer Space Antenna (LISA) would facilitate a comprehensive test of general relativity by simultaneously measuring all the post-Newtonian (PN) coefficients. Multiband observations would measure most of the known PN phasing coefficients to an accuracy below a few percent---two orders-of-magnitude better than the best bounds achievable from even `golden' binaries in the 3G or LISA bands. Such multiparameter bounds would play a pivotal role in constraining the parameter space of modified theories of gravity beyond general relativity.

Gravitational Forces in the Randall-Sundrum Model with a Scalar Stabilizing Field

description: We consider the problem of gravitational forces between point particles on the branes in a five dimensional (5D) Randall-Sundrum model with two branes (at $y_1$ and $y_2$) and $S^1/Z_2$ symmetry of the fifth dimension. The matter on the branes is viewed as a perturbation on the vacuum metric and treated to linear order. In previous work \cite{ad} it was seen that the trace of the transverse part of the 4D metric on the TeV brane, $f^T(y_2)$, contributed a Newtonian potential enhanced by $e^{2βy_2} \cong 10^{32}$ and thus produced gross disagreement with experiment. In this work we include a scalar stabilizing field $ϕ$ and solve the coupled Einstein and scalar equations to leading order for the case where $ϕ_{0}^2/M_{5}^3$ is small and the vacuum field $ϕ_{0}(y)$ is a decreasing function of $y$. $f^T$ then grows a mass factor $e^{-μr}$ where however, $μ$ is suppressed from its natural value, $\mathcal{O}(M_{Pl})$, by an exponential factor $e^{-(1+λ_b)βy_2}$, $λ_b > 0$. Thus agreement with experiment depends on the interplay between the enhancing and decaying exponentials. Current data eliminates a significant part of the parameter space, and the Randall-Sundrum model will be sensitive to any improvements on the tests of the Newtonian force law at smaller distances.

Towards development of a 3-state self-paced brain computer interface system
Creators: name: Bashashati, Ali
Publisher: name: University of British Columbia
Year: 2011

description: Brain computer interface (BCI) systems aim at helping individuals with motor disabilities by providing them the ability to control devices such as wheelchairs and computers, using their brain activity only. The majority of BCI research to-date has focused on developing technology for "synchronous" BCIs. These systems allow the user to affect control during specified time periods only. Self-paced (asynchronous) BCIs on the other hand, are designed to respond whenever the user intends to control the system, otherwise they remain in the so called "inactive output state". This dissertation pursues two main objectives: (1) improving the performance of the existing 2-state self-paced BCI system developed at the Neil Squire Society, Vancouver, Canada (initial evaluations of this system on eight subjects showed mean true positive (TP) rates of 51.3% and 27.5% at false positive (FP) rates of 2% and 1%, respectively.) and (2) designing the first 3-state self-paced BCI. At first, a comprehensive survey of signal processing algorithms in BCI systems is conducted. This survey is the first comprehensive review that covers more than 300 BCI published papers and introduces a taxonomy for signal processing in BCI systems. To achieve the first objective, four separate studies related to the feature extraction and feature classification blocks of the 2-state self-paced BCI are conducted. These studies increase the mean TP rate of the existing system to 73.5% and 47.3% at the FP rates of 2% and 1%, respectively. In these studies, the users were not allowed to control the BCI in 15-34% of the time due to the presence of eye blinks. Thus, another study is also conducted to evaluate the system when the users were allowed to control the output even during eye blinks. Results show slight decrease in TP rates (mean TP rates of 68.0% and 40.6% at the FP rates of 2% and 1%, respectively) with the advantage of providing full control of the system. To achieve the second objective, two new set of movements (right and left hand extension movements) which have not been previously used in the context of BCI systems are used to control the new 3-state self-paced BCI. Results on four able-bodied subjects show significant improvements in detecting the presence of a movement when the system is used in the context of a 2-state self-paced BCI. The mean TP rate is 73.4% at the FP rate of 1%. Initial evaluations of the proposed 3-state self-paced BCI show promise with mean right and left true positive rates of 42.2% and 51.9% at a false positive rate of 1%.
Blind Normalization of Speech From Different Channels

Subjects: subject: Computation and Language (cs.CL)

description: We show how to construct a channel-independent representation of speech that has propagated through a noisy reverberant channel. This is done by blindly rescaling the cepstral time series by a non-linear function, with the form of this scale function being determined by previously encountered cepstra from that channel. The rescaled form of the time series is an invariant property of it in the following sense: it is unaffected if the time series is transformed by any time-independent invertible distortion. Because a linear channel with stationary noise and impulse response transforms cepstra in this way, the new technique can be used to remove the channel dependence of a cepstral time series. In experiments, the method achieved greater channel-independence than cepstral mean normalization, and it was comparable to the combination of cepstral mean normalization and spectral subtraction, despite the fact that no measurements of channel noise or reverberations were required (unlike spectral subtraction).

description: The stopping power of protons and deuterons in low energy collisions with helium gas targets is investigated with the numerical solution of the time-dependent Schrödinger coupled-channels equations using molecular orbital wavefunctions. It is shown that at low projectile energies the energy loss is mainly due to nuclear stopping, charge exchange, and the excitation of low energy levels in the target. The second and third mechanisms, called electronic stopping, dominate for E>200 eV. At lower energies it is also shown that a threshold effect is responsible for a quick drop of the energy loss. This investigation sheds more light on the long standing electron screening problem in fusion reactions of astrophysical interest.

description: We review the potential of long and intermediate baseline reactor neutrino experiments in measuring the mass and mixing parameters. The KamLAND experiment can measure the solar mass squared difference very precisely. However it is not at the ideal baseline for measuring the solar neutrino mixing angle. If low-LMA is confirmed by the next results from KamLAND, a reactor experiment with a baseline of 70 km should be ideal to measure precisely the solar neutrino mixing angle. If on the contrary KamLAND re-establishes high-LMA as a viable solution, then a 20--30 km intermediate baseline reactor experiment could yield very rich phenomenology.

description: We re-examine the original model of Natural inflation, in which the inflaton is a pseudo Nambu-Goldstone boson with potential of the form $ V(ϕ) = Λ^4 [1 \pm \cos(ϕ/f)]$, in light of recent data. We find that the model is alive and well. Successful inflation as well as recent data from the Wilkinson Microwave Anisotropy probe require $f > 0.6 m_{\rm Pl}$ (where $m_{\rm Pl} = 1.22 \times 10^{19}$ GeV) and $Λ\sim m_{GUT}$, scales which can be accommodated in particle physics models. The detectability of tensor modes from natural inflation in upcoming microwave background experiments is discussed. We find that natural inflation predicts a tensor/scalar ratio within reach of future observations.

title: Exploring the nature of student consumerism at postsecondary institutions in British Columbia, Canada
Creators: name: James, Edwin Arthur Hugo
Publisher: name: The Open University
Year: 2016

description: The notion that students can be seen as consumers in the marketplace of higher education -- in much the same way as they are viewed as consumers in other markets -- has been around for several decades but has received little empirical investigation or scholarship, despite being the topic of considerable popular discourse and often with very polarized opinions expressed. This research study explored the context within which the phenomenon of student consumerism has arisen, and focused specifically on exploring that phenomenon within postsecondary institutions in British Columbia (BC), Canada. The thesis reports on a qualitative investigation into the nature of student consumerism among students in postsecondary institutions in BC. Data were collected using focus groups and semi-structured interviews that explored with student participants to what extent, and in what ways, students perceive themselves to be, and to behave as, consumers -- and whether these findings vary among students in different programmes or types of institutions in BC.

description: There are over 170 products listed for pest control with the Pesticide and Toxic Chemicals Board (PCB) of the Ministry of Agriculture (MOA) in Antigua and Barbuda. Safe handling and application of these products is crucial to achieving desired pest control and to protecting non-target organisms and the environment. The Pesticide and Toxic Chemicals Act of 2007 dictates that any person performing pest control activities for remuneration must be certified to do so. The MOA partnered with University of Florida/ IFAS to develop a pesticide certification training module modeled after the Florida program. The objectives of the module are to enhance the knowledge base of pest control applicators on identification of pests, on control options, and on safe use of pesticides, and to ensure that all actions governing the use of pesticides are in accordance with the requirements of the Act. A team of five UF/IFAS faculty members developed a needs assessment survey and modified the Florida curriculum based on the results of the survey submitted by the MOA. The module included four training categories: core (to be taken by all participants), structural pests, lawn and ornamentals, and agriculture. A one-week training session was conducted in January 2009; it was attended by 65 people that represented the various categories, and by MOA personnel. Sixty-three participants took the core exam and one category exam. Thirty-one participants passed both the core and a category exam and were certified through the PCB. A regular training and exam schedule is needed for pest control applicators to ensure compliance with the Act and proper pesticide usage to protect pesticide users, public health, and the environment.

description: We consider the equations for the coefficients of stationary rotating axisymmetric metrics governed by the Einstein-Euler equations, that is, the Einstein equations together with the energy-momentum tensor of a barotropic perfect fluid. Although the reduced system of equations for the potentials in the co-rotating co-ordinate system is known, we derive the system of equations for potentials in the so called zero angular momentum observer co-ordinate system. We newly give a proof of the equivalence between the reduced system and the full system of Einstein equations. It is done under the assumption that the angular velocity is constant on the support of the density. Also the consistency of the equations of the system is analyzed. On this basic theory we construct on the whole space the stationary asymptotically flat metric generated by a slowly rotating compactly supported perfect fluid with vacuum boundary.

description: The quantum dynamics of a bulk-boundary theory is closely examined by the use of the background field method. As an example we take the Mirabelli-Peskin model, which is composed of 5D super Yang-Mills (bulk) and 4D Wess-Zumino (boundary). Singular interaction terms play an important role of canceling the divergences coming from the KK-mode sum. Some new regularization of the momentum integral is proposed. An interesting background configuration of scalar fields is found. It is a localized solution of the field equation. In this process of the vacuum search, we present a new treatment of the vacuum with respect to the extra coordinate. The "supersymmetric" effective potential is obtained at the 1-loop full (w.r.t. the coupling) level. This is the bulk-boundary generalization of the Coleman-Weinberg's case. Renormalization group analysis is done where the correct 4d result is reproduced. The Casimir energy is calculated and is compared with the case of the Kaluza-Klein model.

description: Managing household electricity consumption plays an important role in the overall energy management spectrum. This paper presents an analysis of the main factors that contribute to household electricity consumption. Emphasis is given on consumer behaviour in relation to household characteristics. For this purpose, primary data is collected via a survey study from a representative sample of households. The data were analysed using correlational as well as regression analysis methods. It was found that electricity consumption is a social phenomenon, with economic and technological dimensions. Further, it was verified that energy-saving techniques such as insulation, modern building materials and renewable energy make a significant difference in the electricity cost. Moreover, specific types of electrical appliances are highly correlated with electricity consumption.

description: We consider the 2D Landau Hamiltonian $H$ perturbed by a random alloy-type potential, and investigate the Lifshitz tails, i.e. the asymptotic behavior of the corresponding integrated density of states (IDS) near the edges in the spectrum of $H$. If a given edge coincides with a Landau level, we obtain different asymptotic formulae for power-like, exponential sub-Gaussian, and super-Gaussian decay of the one-site potential. If the edge is away from the Landau levels, we impose a rational-flux assumption on the magnetic field, consider compactly supported one-site potentials, and formulate a theorem which is analogous to a result obtained in the case of a vanishing magnetic field.

description: Spin ices are exotic phases of matter characterized by frustrated spins obeying local ice rules, in analogy with the electric dipoles in water ice. In two dimensions, one can similarly define ice rules for in-plane Ising-like spins arranged on a kagome lattice. These ice rules require each triangle plaquette to have a single monopole, and can lead to various unique orders and excitations. Using experimental and theoretical approaches including magnetometry, thermodynamic measurements, neutron scattering and Monte Carlo simulations, we establish HoAgGe as a crystalline (i.e. non-artificial) system that realizes the kagome spin ice state. The system features a variety of partially and fully ordered states and a sequence of field-induced phases at low temperatures, all consistent with the kagome ice rule.

description: The linkages between agriculture and tourism in the U.S. Virgin Islands are limited by a number of constraints. Opportunities were identified to improve the linkages related to local food chains. Strategic educational and informational exchange opportunities were developed for farmers and chefs. The University of the Virgin Islands Cooperative Extension Service and the Virgin Islands Department of Agriculture (VIDA) sponsored Farmer-Chef Connection events. Locally grown produce was provided to participating restaurants which prepared dishes featuring the items provided. Farmers and chefs were brought face-to-face when the dishes were presented and shared at events on St. Thomas and St. Croix. The VIDA is differentiating quality local produce from imports through various endeavors such as the Virgin Fresh™ branding and marketing campaign. The farmer-chef connection events stimulated two private entities to hold the first V.l. Ultimate Chef Competition, an activity featuring Virgin Fresh™ produce. Relationships between farmers and chefs present mutually beneficial opportunities for niche market sales from small farms to local restaurants and hotels. Farmers benefit from restaurateurs' willingness to pay higher prices for produce meeting their standards. Chefs benefit from having sources of fresh produce and an introduction to local items not normally found at the supermarket or wholesale distributor. Restaurants use their local purchases as marketing tools, since many residents support the idea of buying local. Demands for authentic Caribbean cuisine also encourage restaurants to feature local produce on the menus. Challenges to creating farmer-chef connections include higher up-front costs of local produce, business-culture differences between farmers and restaurateurs, supply chain logistic issues (i.e., order placement, delivery, consistency of supply) and food safety concerns.

description: We employ quantum mechanical principles in the computability exploration of the class of classically noncomputable Hilbert's tenth problem which is equivalent to the Turing halting problem in Computer Science. The Quantum Adiabatic Theorem enables us to establish a connection between the solution for this class of problems and the asymptotic behaviour of solutions of a particular type of time-dependent Schrödinger equations. We then present some preliminary numerical simulation results for the quantum adiabatic processes corresponding to various Diophantine equations.

description: Anyons with arbitrary exchange phases exist on 1D lattices in ultracold gases. Yet, known continuum theories in 1D do not match. We derive the continuum limit of 1D lattice anyons via interacting bosons. The theory maintains the exchange phase periodicity fully analogous to 2D anyons. This provides a mapping between experiments, lattice anyons, and continuum theories, including Kundu anyons with a natural regularization as a special case. We numerically estimate the Luttinger parameter as a function of the exchange angle to characterize long-range signatures of the theory and predict different velocities for left- and right-moving collective excitations.

description: The transition in the energy sector, initiated by increasing uptake of distributed energy
resources (DER) and grid digitization, provides opportunities to improve energy efficiency through elec-tricity market reformation. The development of a two-sided market allows delivering benefits of improved
efficiency to energy customers. This paper discusses the opportunities and challenges related to transitioningto a two-sided energy market. The drivers to move toward a two-sided market, the benefits that this market canprovide for different stakeholders, and enabling technologies for this transition are studied. An overview ofdifferent approaches that lay the groundwork for two-sided markets, including demand response (DR), virtualpower plants (VPPs), peer-to-peer (P2P) trading, and transactive energy (TE) is provided. A classificationof different approaches, along with examples of academic and industrial works, are presented to give someinsights on the way each approach can pave the path to the market reformation. Finally, different approachesare compared and some of the challenges that need to be addressed in future works are identified.

description: This article describes and provides preliminary estimates of the potential economic losses that could result from an incursion of the recently discovered exotic laurel wilt disease caused by Raffaelea lauricola, in the main avocado (Persea americana) growing area of Florida. Estimates are provided for both the direct losses as well as the indirect or "spillover" losses that could occur across the rest of the regional economy. The Impact Analysis for PLANning (IMPLAN) input-output multipliers were used in assessing the regional impacts. The results of the investigation indicate the direct loss to the industry in terms of lost sales, property damage, and increased management costs could range from $356 million in a do-nothing situation to about $183 million if damage control measures were 50% effective. If increased management costs and decreased property values are ignored, the adverse impact on the regional economy could range from $54 million in a do-nothing situation to $27 million in a case in which the treatments result in only a 50% reduction in avocado production.
Membrane binding properties of prothrombin and other gamma-carboxyglutamic acid-containing coagulation proteins

description: Haemostasis is a highly regulated, fundamental, physiological process featuring numerous peripheral membrane proteins. Of these, the membrane and calcium binding properties of the vitamin K-dependent proteins are dependent on a common N-terminal γ-carboxyglutamic acid (Gla)-containing domain. Previous work on Gla proteins has provided a wealth of affinity and kinetic membrane binding information. These studies have employed a number of biophysical techniques using artificial phosphatidylserine-containing model membranes. However, many aspects of the membrane binding interaction, in terms of mechanism and modulation by protein cofactor remain obscure. This thesis examines two methods for studying the membrane binding properties of human plasma derived Gla proteins with emphasis on prothrombin. In Chapter 3 differential centrifugation combined with immunoaffinity detection was used to quantify the effect the cofactor Factor Va had on the membrane binding affinity of prothrombin for membrane. Factor Va bound to anionic phospholipid membrane undoubtedly enhanced the membrane binding affinity of prothrombin relative to prothrombin binding in the absence of the cofactor. Thus, these results indicate that Factor Va can recruit prothrombin or prethrombin 1, a Gla-domain less fragment of prothrombin, to the membrane surface, plausibly contributing to its cofactor function. In Chapters 4 and 5, surface plasmon resonance (SPR) was used to evaluate the Ca²⁺-specific binding properties of a number of Gla proteins to immobilized membranes. Membrane affinity, molar binding preference and kinetics controlling complex formation and complex breakdown varied widely between Gla proteins. The comparative results obtained by SPR indicate that the majority of homologous Gla proteins bind membranes with a complex mechanism which may involve membrane induced protein dimers. Unlike prothrombin, the binding profiles for fragment 1 and fragment 1.2 fitted closely to a one-site binding model. Apparent biphasic association and biphasic dissociation phases were observed for prothrombin and commonly amongst the other Gla proteins at a wide range of protein concentrations including physiological concentrations. For prothrombin, dimerization appears to be specific to the protease domain as neither fragment 1 nor fragment 1.2 displays such binding complexities. It is possible that dimerization increases the half-life of membrane-bound Gla proteins thereby promoting their participation in complex assembly and function.
