Molecular biology of peripheral nerve regeneration: Expression and role of Netrin-1, DCC and Runx2
… its receptor - deleted in colorectal carcinoma (DCC). To study the role of DCC in peripheral nerve injury and repair, I generated a global knockout of DCC in adult mice using a Tamoxifen inducible Cre recombinase system. A transection injury in DCC global knockout mice revealed aberrant …

Netrin Guides Spinal Commissural Axons to the Midline at Long Range Through the Receptors Dcc and Neogenin
… the differential roles for Netrin-1 receptors, Dcc and Neo1. How these two Netrin receptors collaborate during midline crossing has yet to be fully examined. Using transgenic embryos that express Cre-recombinase within discrete spinal interneuron populations in combination with fluorescent …

The Intracellular Domain of the Frazzled/Dcc Receptor is a Transcription Factor Required for Commissural Axon Guidance
… guidance receptor Deleted in Colorectal Cancer (DCC), functions as a transcription factor to control axon responsiveness to the embryonic ventral midline. In Chapter 1, I introduce the embryonic ventral midline as a model system for studying how axons modulate their responsiveness to guidance …

Signal Transduction Mechanisms in Commissural Axon Guidance: The Role of Intracellular Tyrosine Kinases in Netrin-Dcc/Frazzled Axon Attraction
… symmetric animals studied to date through the DCC family of receptors. In Drosophila, commissural neurons require Netrin and its DCC receptor, Frazzled, for midline axon crossing. To identify genes that function in Netrin signal transduction in vivo, we have taken two approaches: (1) a …

Organ donation after death determination by circulatory criteria: Evaluation of two controversial practices
… criteria or by circulatory criteria (DCC). This thesis evaluates two controversial practices specific to DCC: (1) antemortem heparin administration to DCC donors with the aim of improving organ function, and (2) cardiac donation after DCC, which has not yet been adopted in Canada. …

Synthetic and mechanistic studies to expand the scope of alkyne metathesis dynamic covalent chemistry
Dynamic covalent chemistry (DCC) is a widely applied method for the synthesis of diverse molecular architectures and chemical libraries which are of broad interest in a number of chemical disciplines. As part of the greater subset of molecular self-assembly processes, DCC allows for the assembly of …

Decellularized cartilage as a chondroinductive material for cartilage tissue engineering
… develop and evaluate decellularized cartilage (DCC) as a chondroinductive material for cartilage tissue engineering applications. This work was successful in developing a decellularization method for hyaline cartilage fragments that removed 99% of cells, while retaining 87% of GAGs and also in …

Band to Band Calibration and Relative Gain Analysis of Satellite Sensors Using Deep Convective Clouds
… Landsat 8 using SCIAMACHY Deep Convective Cloud (DCC) spectra. Second, a novel method to derive relative gains using DCCs and improve the image quality of cirrus band scenes was developed. DCCs are very cold, bright clouds located in the tropopause layer. At small sun elevation and sensor viewing …

On modelling volatility and mortality for pension schemes
… study of various advance multivariate DCC GARCH models which are used for construction of optimal portfolios in modelling asset return covariances. The effectiveness of using parametric copula in estimating portfolio risk measures are evaluated such that the DCC models are found to have …

User interface design and evaluation of a shipboard electronic warfare console
… of the AN/SLQ-32(V) Display Control Console (DCC). The DCC provides Navy operators with bearing and threat information for radar emitters. The task of emitter identification was used to test potential redesigns. There is no research to substantiate the current or possible redesign solutions. …

Modelling interdependence in a pair of heating oil and natural gas futures curves
… based on hierarchical Archimedian copula (HAC-DCC). The conducted analysis allowed to forecast the distribution of the returns of any portfolios composed of the available futures contracts for short time periods. As shown in the study, value-at-risk estimates derived from the forecasts produced …

A dynamic optimal control system for complex compressed air networks
… solution. The Dynamic Compressor Controller (DCC) discussed in this thesis solves this problem. The DCC accomplishes this by calculating multiple compressed air set points - one for each individual compressor. These set points take the location and demand of the compressed air network into …

Investigation of the roX RNAs and the RNA Helicase MLE in Dosage Compensation in Drosophila melanogaster
… is mediated by the dosage compensation complex (DCC), which is assembled in a sequential manner on the male X chromosome and is composed of the two noncoding roX (RNA on the X) RNAs and at least five proteins, including the RNA helicase Maleless (MLE). MLE contains two highly conserved double …

Understanding reaction pathways leading to tetrahedral organic cages via alkyne metathesis
… POCs via multitopic dynamic covalent chemistry (DCC) has been demonstrated. The common view of successful DCC syntheses is that they proceed reversibly, ultimately allowing “error-correction” to provide thermodynamically favored products. The current approach to synthesize molecular cages is to …

Segmentação de imagens fetais com potencial para desenvolvimento de ferramentas de apoio ao diagnóstico
… automática da medida da Distância Crânio-Caudal (DCC) a partir das imagens de ultrassons habitualmente usadas para este fim. Para tal, propõe a utilização de técnicas de Fuzzy Clustering, de Contornos Ativos e de Aprendizagem Máquina, nomeadamente SVMs, para a segmentação das imagens com vista à …

Sema-1a Reverse Signaling Promotes Midline Crossing In Response To Secreted Semaphorins
… part on the highly conserved guidance receptor DCC, or Frazzled in Drosophila, which signals chemoattraction upon binding its ligand, Netrin. DCC mutations in humans are associated with mirror movement disorder, an inability to independently control the right and left sides of the body. Although …

The role of Ena/VASP and associated proteins in regulation of neuronal morphology and filopodia architecture
… the axon guidance cue Netrin-1 and its receptor DCC. I have shown Trim9 binds the cytoplasmic tail of DCC and also binds Ena/VASP proteins and Myosin-X, which are cytoskeletal effectors downstream of Netrin-1. I discovered that inhibition of Trim9 ubiquitin ligase activity specifically blocks …
