Protein interaction networks and protein compartmentalization underlie all signaling and regulatory processes in cells. Traditional approaches to proteomics employ mass spectrometry (MS) coupled to biochemical fractionation or affinity purification but require cell lysis prior to analysis which often results in false-negatives from missed interactions or incomplete purification and false-positives from contaminants. Enzyme-catalyzed proximity labeling (PL) has emerged as a new approach to study the spatial and interaction characteristics of proteins in which a PL enzyme can be genetically targeted to a subcellular region and used to tag surrounding endogenous proteins with a chemical handle that allows their identification by MS. Tagging is carried out in living cells in a distance-dependent manner, allowing data collection from a physiologically relevant environment with preservation of spatial information. Current PL methods are limited by poor catalytic efficiency or toxic substrates that limit their application in vivo. Therefore, we have developed a new proximity labeling method, called TurboID, that uses non-toxic labeling conditions and has high catalytic efficiency that allows its use in a wide variety of biological contexts. Here, we describe our use of yeast display-based directed evolution to engineer two promiscuous mutants of biotin ligase, TurbolD and miniTurbo. We describe our characterization of the evolved PL enzymes in microbes, cultured cells, in vitro, and in vivo in flies and worms, and show that TurbolD and miniTurbo have much greater catalytic efficiency than any other biotin ligase-based PL method currently available. Lastly, we demonstrate that TurbolD and miniTurbo can be used to obtain proteomes with the same size, specificity, and depth-of-coverage as existing biotin-ligase based PL techniques with over 100- fold shorter labeling times. In the Appendix, we discuss two separate projects. In Part I, we describe how fusion of the PL enzyme APEX2 to various mitochondrial proteins could be used to map the proteomes of mitochondrial subdomains and be used to visualize the localization of mitochondrial proteins in mitochondrial subdomains using APEX2 to generate contrast for electron microscopy imaging. In Part II, we discuss the development of two platforms that could be used to temporally control genome editing using light.

Full textCell fate and fitness depend on the protein content, and in particular on the interaction networks (also called interactomes) connecting the different proteins. Proteins have the general property to engage in diverse and occasionally overlapping macromolecular assemblies, each serving distinct purposes. Therefore, identifying protein-protein interactions (PPIs) and linking them to complexes is a crucial yet challenging issue in biology. This issue was at the core of my PhD work. The first part of my work was dedicated to the improvement of an existing method for capturing novel PPIs in the context of defined biological functions. This work was established with ERK1, which is a key downstream regulator of several signaling pathways involved in many different cancers. The new tools were tested in the context of two different inhibitory molecules to capture drug-sensitive interactions of ERK1 in human HEK293T cells. One such interaction was confirmed at the functional and molecular levels, by using an original imaging strategy to access the PPI dynamics in live cells. The second part of my PhD work was dedicated to the establishment of a pioneer methodology to capture endogenous PPIs established by a specific dimeric protein complex in human live cells. This methodology couples Bimolecular Fluorescence Complementation (BiFC) and proximity biotin labelling technologies. More specifically, it is based on a GFP-nanobody directed toward the BiFC complex and fused to the TurboID biotin ligase. Tools were established to map TAZ/14-3-3 and TAZ/TEAD complexes interactome, which translate the activity of the Hippo signaling pathway in the cytoplasm and nucleus, respectively. Our approach allowed capturing specific interactomes of the two dimeric protein complexes and identifying a novel key regulator of TAZ/14-3-3 complexes in a cancer cell context. Collectively, my PhD work introduced two complementary methodologies for deciphering PPI networks in the context of specific biological functions or in the context of a specific protein complex in human live cells. These approaches provide a novel dimension for understanding protein functions and the underlying interactomes in normal or pathological cell contexts

Full textCette thèse explore quatre méthodes pour l'amélioration de la spectroscopie de réflectance diffuse quantitative dans des milieux qui diffusent la lumière. En introduction, une description des théories de la propagation de la lumière dans des médias qui diffusent celle-ci, des instruments pour mesurer les propriétés de diffusion, des méthodes de traitement des données spectrales, et des bioanalytes avec activité optique est donné. Un nouvel appareil à «temps de vol de photon» est présenté. Cet instrument portatif est utilisé pour mesurer le coefficient de dispersion en tandem avec un spectromètre à diode portable. Les coefficients de diffusion mesurés sont ensuite utilisés pour corriger la dispersion dans les spectres infrarouges co-mesurée, ainsi que l'amélioration de la quantification. Les coefficients de dispersion ont été mesurés avec une variation de 11,6% à 850 nm et 14,1% à 905 nm. En prenant en compte la dispersion, les estimations de la concentration de teinture ont été améliorées de 35%. Un nouvel appareil utilisant les modes d'imagerie annulaire pour mesurer les coefficients de dispersion et d'absorption est présenté. Les coefficients de dispersion ont été mesurés avec un coefficient de variation de 12,6%, et les coefficients d'absorption ont été mesurés avec un coefficient de variation amélioré de 50% par rapport aux méthodes d'imagerie traditionnelle. Une nouvelle méthode pour améliorer l'utilisation des mesures de simplicité dans le développement de méthodes de traitement des données via des algorithmes génétiques est présentée.

Full textLa qualité globale des eaux continentales (lacs et réservoirs) continue à se détériorer dans de nombreuses régions du Mexique. Le réservoir Cointzio, situé dans la partie sud du Plateau Central Mexicain, sur la ceinture “Trans-Mexicain Volcanique Belt » (TMVB), ne fait pas exception. Ce réservoir tropical turbide est un système monomictique chaud (surface = 6 km2, capacité = 66 Mm3, temps de séjour ~ 1 an). Il est stratégique pour l'approvisionnement en eau potable de la ville de Morelia, capitale de l'état du Michoacán, et pour l'irrigation en aval pendant la saison sèche. Le réservoir est menacé par l'accumulation des sédiments et des nutriments provenant d'eaux non traitées dans le bassin versant amont. La haute teneur en particules d'argile très fines et le manque d'installations de traitement de l'eau conduisent à de graves épisodes d'eutrophisation (jusqu'à 70 µg chl. a L-1) ainsi qu'à des périodes saisonnières de forte turbidité (profondeur de Secchi < 30 cm) et d'anoxie (de Mai à Octobre). Sur la base de mesures intensives de terrain réalisées en 2009 (échantillonnage dans le bassin versant, sédiments déposés, profils verticaux de l'eau, bilan entrées et sorties) nous avons présenté une étude intégrée du fonctionnement hydrodynamique et biogéochimique du réservoir Cointzio. Les profils verticaux de température (T), de concentration en sédiment en suspension (TSS), d'oxygène dissous (DO), de chlorophylle a, de carbone et de nutriments ont été utilisés pour évaluer les cycles internes au réservoir. Pour compléter l'analyse des données de terrain, nous avons examiné la capacité de différents modèles numériques 1DV (Aquasim modèle biogéochimique couplé avec le modèle de mélange k-ε) à (i) reproduire les principaux cycles biogéochimiques dans le réservoir Cointzio et (ii) préciser les scénarios de réduction des éléments nutritifs (P and N) pour limiter l'eutrophisation dans les prochaines décennies. Le modèle k-ε s'est avéré le plus robuste pour reproduire les conditions hydrodynamiques, en particulier la stratification modérée liée à la très grande turbidité et au régime soutenu de vent thermique. Le modèle Aquasim s'est avéré pertinent pour reproduire les principaux cycles de l'oxygène dissous DO, des nutriments et de la chlorophylle a au cours de l'année 2009. Les différentes simulations ont souligné l'impact négatif à long terme du réchauffement climatique. A la fin du siècle (2090), une augmentation de la température de l'air atteignant 4.4° C a été prédite à partir de modèles de circulation mondiale. Couplé avec une année hydrologique sèche, une telle situation pourrait conduire à des conditions anoxiques sévères et à des blooms importants de chlorophylle a (jusqu'à de 94 µg L-1). Diverses simulations ont montré que la réduction drastique de l'apport de nutriments (à 90%) serait nécessaire pour réduire de façon significative les teneurs en chlorophylle a. Si de telles mesures d'atténuation sont adoptées, le pic maximal de chlorophylle a se stabiliserait à 40 µg L-1, au lieu de 94 mg L-1, après une période de cinq ans d'efforts. À notre connaissance, cette étude fournit la première application numérique de modèles k-ε et AQUASIM pour simuler les niveaux d'eutrophisation élevés dans un réservoir tropical très turbide

The ocean depths provide an ever changing and complex imaging environment. As scientists and researches strive to document and study more remote and optically challenging areas, specifically scatter-limited environments. There is a requirement for new illumination systems that improve both image quality and increase imaging distance. One of the most constraining optical properties to underwater image quality are scattering caused by ocean chemistry and entrained organic material. By reducing the size of the scatter interaction volume, one can immediately improve both the focus (forward scatter limited) and contrast (backscatter limited) of underwater images. This thesis describes a relatively simple, cost-effective and field-deployable low-power dynamic lighting system that minimizes the scatter interaction volume with both subjective and quantifiable improvements in imaging performance.

The medical field is currently experiencing rapid growth in the area of optical diagnostics. Minimally-invasive spectroscopic and imaging modalities enable physicians to make increasingly accurate diagnoses in real time, without the cost and delay associated with traditional reliance on histopathology. We have developed an ultra-high resolution interferometric system which is well suited for clinical diagnostic applications. The interferometric system has a spatial resolution of 0.1 nm and a temporal resolution of 3 ns. We have utilized this high resolution interferometric system in two novel minimally invasive techniques. Both techniques measure surface deformation of a target after absorption of a short laser pulse. The time dependent surface deformation is a function of the target's spatially resolved optical, thermal and mechanical properties. Therefore, accurate measurement of surface displacement can be used to extract significant diagnostic information. The first technique is termed Interferometric Photomechanical Spectroscopy (IPMS), and is used to measure effective optical absorption depth of a sample. We used IPMS to measure effective absorption depth of both diffuse and speculary reflecting targets including well characterized colored glass samples and gelatin based tissue phantoms.
(cont.) phantoms. The second technique is termed Interferometric Photomechanical Tomography (IPMT), and is used to image sub-surface absorbers such as tumors or blood vessels. IPMT combines high optical contrast with low attenuation of sound propagation to localize sub-surface absorbers in highly scattering media. We have used IPMT to image sub-surface blood vessels in a phantom model and in vivo. Interferometric techniques compare favorably against diagnostic techniques which measure surface stress instead of surface displacement. This is primarily because interferometry is a non-contact epitaxial method capable of high resolution point measurements. Further, an interferometric system is easily implemented into an optical fiber setup for use in minimally- invasive catheter based procedures.

Full textThis thesis analyses the potential of single-pixel imaging (SPI) techniques to obtain images through turbid media, particularly biological tissue. The SPI technique employs structured illumination (generated by a spatial light modulator) and integrated detection (using a sensor without spatial resolution). This optical architecture allows us to work in exotic regions of the spectrum (where pixelated detectors do not exist) and to obtain multidimensional images (for example, hyperspectral and/or polarimetric images) using a suitable detector. This work shows the capability of SPI techniques to attenuate the image quality decrease caused by light scattering in applications such as image transmission through diffusers (static or dynamic), imaging objects embedded in biological tissue of millimeter thickness, and imaging the human retina in vivo, as well as the retina of an artificial eye with cataract (simulated by a turbid media).

Concentrations of blood constituents provide diagnostic information in clinical procedures. Among the medical community, there is great interest in developing an optical method of concentration measurements that eliminates reagents required in the current clinical chemistry techniques and is non-invasive. This thesis describes the methodology to develop a measurement technique of blood component concentrations using Raman spectroscopy. The sources of prediction error were identified. A Monte Carlo simulation model was developed to study the distribution of the Raman signal from turbid biological samples. A high sensitivity system for Raman spectroscopy of blood analytes was designed by optimizing the optical components. The new system had higher collection efficiency than the previous state-of-the-art system. Experiments were performed using the new system in order to collect Raman spectra of human whole blood. The collected Raman spectra were analyzed with multivariate calibration techniques, and compared with hospital measurements. The analysis of the spectra of whole blood samples demonstrate that many chemical components in ex vivo whole blood samples can be measured accurately with near-infrared Raman spectroscopy. A preliminary analysis based on the results of this thesis indicates that it is feasible to measure blood analytes non-invasively.

Full textDie vereinfachte Annahme eines turbiden Mediums findet in der Theorie des Strahlungstransfers für Vegetationsmedien breite Anwendung. Darin werden orientierte ebene Modellblätter angenommen, deren Normalen stets in den oberen Halbraum weisen. Diese Orientierungen werden mittels sogenannter Blattnormalenverteilungen (BNV) beschrieben, so dass sich im Rahmen der turbiden Theorie eine Strahlungstransfergleichung ableiten lässt, in der die sogenannte Ross-Nilson-Funktion G explizit auftritt. Diese von J. Ross eingeführte Funktion basiert auf geometrischen Betrachtungen und wird daher auch Geometriefunktion genannt oder kurz G-Funktion. G muss zur Lösung der vorigen Gleichung bekannt sein. Es leitet sich aus der BNV ab und konnte in expliziter sowie analytischer Form bislang lediglich für stark vereinfachte BNV hergeleitet werden. Wie wir an dieser Stelle in einem früheren Beitrag gezeigt haben, lässt sich G darüber hinaus für andere standardisierte BNV berechnen. Auf letzteren aufbauend führen wir jetzt eine verallgemeinerte trigonometrische BNV ein und präsentieren die entsprechende Formel für G.

Full textNew high quality mobile telecommunication services are offered everyday and the demand for higher data rates is continuously increasing. To maximize the uplink throughput in HSPA when transmission is propagated through a dispersive channel causing self-interference, equalizers are used. One interesting solution, where the equalizer and decoder exchange information in an iterative way, for improving the equalizer performance is Turbo equalization.
In this thesis a literature survey has been performed on Turbo equalization methods and a chosen method has been implemented for the uplink HSPA standard to evaluate the performance in heavily dispersive channels. The selected algorithm has been adapted for multiple receiving antennas, oversampled processing and HARQ retransmissions. The results derived from the computer based link simulations show that the implemented algorithm provide a gain of approximately 0.5 dB when performing up to 7 Turbo equalization iterations. Gains up to 1 dB have been obtained by disabling power control, not using retransmission combining and utilizing a single receiver antenna. The algorithm has also been evaluated considering alternative dispersive channels, Log-MAP decoding, different code rates, number of Turbo equalization iterations and number of Turbo decoding iterations.
The simulation results do not motivate a real implementation of the chosen algorithm considering the increased computational complexity and small gain achieved in a full featured receiver system. Further studies are needed before concluding the HSPA uplink Turbo equalization approach.

Resumo: Neste trabalho apresentamos classes de códigos turbo não binários definidos sobre os campos e anéis de inteiros. Os códigos turbo multiníveis convencionais consistem em dois códigos componentes RSC M-ários, concatenados via um entrelaçador aleatório de N símbolos e com símbolos codificados transmitidos através da modulação M-PSK. Os códigos turbo híbridos multiníveis consistem em dois códigos componentes RSC, não necessariamente definidos sobre o mesmo alfabeto. Os codificadores componentes são separados por um entrelaçador e os símbolos codificados transmitidos através de um esquema híbrido de modulação PSK. O algoritmo de decodificação iterativa de máximo a posteriori, usado para decodificar os códigos concatenados binários, pode ser estendido para a classe dos códigos turbo não binários. Os resultados das simulações mostram que os códigos turbo híbridos multiníveis apresentam melhor desempenho, error floor mais baixo e menor complexidade de codificação e decodificação que os códigos turbo M-ários convencionais. Já os códigos turbo multiníveis M-ários são mais eficientes que os códigos turbo binários padrão

The conventional multilevel turbo codes consist of two M-ary RSC component codes concatenated via a random N-symbol interleaver and with encoded symbols are transmitted using a M-PSK modulation. The hybrid multilevel turbo codes consist of two RSC component codes, defined on different alphabets. The component encoder are separated by a interleaver and the encoder symbols are transmitted utilizing a hybrid M-PSK scheme. The iterative binary decoding algorithm is a maximum a posteriori scheme, which can be extended to the class of the non-binary turbo codes. The results of the simulations show that the hybrid multilevel turbo codes present better performance, lower error floor and lower encoding and decoding complexities than the M-ary conventional turbo codes. Moreover, the M-ary multilevel turbo codes are more efficient than the standard binary turbo codes
