Abstract:
Sequence databases can be searched for homologies of zinc coordination motifs with characteristic ligand signatures. Ensuing predictions that 3-10 % of the human genes encodes zinc proteins are most remarkable. But they seem conservative when considering that database mining cannot discover new signatures or coordination environments that employ nonsequential binding of ligands and sulfur-ligand bridges. Predictions also fall short for zinc/protein interactions at protein interfaces and for inhibitory zinc sites. Zinc ions transiently target proteins that are not known to be zinc proteins, adding a hitherto unrecognized dimension to the human zinc proteome. Predicted zinc sites need to be verified experimentally. The metal can be absent or sites may bind metal ions other than zinc because protein coordination environments do not have absolute specificity for zinc. The metaphor of the "galvanization of biology" continues to gain prominence in terms of the sheer number of approximately 3000 human zinc proteins and their annotation with new functions. Clearly, description of zinc proteomes cannot be pursued solely in silico and requires zinc proteomics, an integrated scientific approach. Progress hinges on a combination of bioinformatics, biology, and significantly, analytical and structural chemistry.

Abstract:
Data mining in protein databases, derivatives from more fundamental protein 3D structure and sequence databases, has considerable unearthed potential for the discovery of sequence motif—structural motif—function relationships as the finding of the U-shape (Huf-Zinc) motif, originally a small student's project, exemplifies. The metal ion zinc is critically involved in universal biological processes, ranging from protein-DNA complexes and transcription regulation to enzymatic catalysis and metabolic pathways. Proteins have evolved a series of motifs to specifically recognize and bind zinc ions. Many of these, so called zinc fingers, are structurally independent globular domains with discontinuous binding motifs made up of residues mostly far apart in sequence. Through a systematic approach starting from the BRIX structure fragment database, we discovered that there exists another predictable subset of zinc-binding motifs that not only have a conserved continuous sequence pattern but also share a characteristic local conformation, despite being included in totally different overall folds. While this does not allow general prediction of all Zn binding motifs, a HMM-based web server, Huf-Zinc, is available for prediction of these novel, as well as conventional, zinc finger motifs in protein sequences. The Huf-Zinc webserver can be freely accessed through this URL ( http://mendel.bii.a-star.edu.sg/METHODS/hufzinc/ ).

Abstract:
As scientific community worldwide is publishing a huge number of research articles in various fields; it is necessary to distinguish between databases that are efficient and objective for literature searches. This review offers information on the important points of the database. None of the databases are complete and perfect, but they complement each other. If a library can only afford one, choice must be based on the priorities of institutional needs. The benefits that databases can provide in the preparation of the literature review for developing future studies and dissemination of research are discussed. This paper provides an overview of the most frequently used free chemistry databases such as PubChem, Crystallography Open Database, PubMed, ZINC, ChemSpider, and Google Scholar. It also gives a brief description of three major commercial databases such as Scopus, Web of Science, and SciFinder. Thus, substance and citation databases that covers almost all areas of chemistry, has become an invaluable tool in bibliometric analysis.

Abstract:
Pancreatic cancer is relatively uncommon. Despite its relative scarcity, it is the fourth-ranked cancer killer in the Western world with less than a 5% 5-year survival rate. The high mortality rate is due to the asymptomatic nature of the disease and the advanced stage at which it is usually diagnosed. S100P is a calcium-binding protein that has been shown to be highly expressed in the early stages of pancreatic cancer and has been proposed as a potential therapeutic target via the blocking of its interaction with its receptor RAGE, the receptor for advanced glycation end-products. In this thesis, computational techniques were employed on the NMR ensemble of S100P (PDB Accession code 1OZO) to identify potential inhibitors of the S100P-RAGE interaction in the hope of identifying a series of novel leads that could be developed into clinical candidates for the treatment of pancreatic cancer. In silico studies identified putative binding sites at the S100P dimeric interface capable of accommodating cromolyn, an anti-allergy drug shown to bind to the protein both in vitro and in vivo. Virtual screening of >1 million lead-like compounds using 3D pharmacophore models derived from the predicted binding interactions between S100P and cromolyn, identified 9,408 'hits'. These were hierarchically clustered according to similarities between chemical structures into 299 clusters and 77 singletons. Biological screening of 17 of the 'hits' identified from virtual screening stuidies, 4 of which were synthesised in-house, against pancreatic cancer cell lines identified five compounds that demonstrated an equal or greater capacity to reduce BxPC-3 S100P-expressing pancreatic cells' metastatic potential in vitro relative to cromolyn. Compound 24 in particular, showed significant (p<0.05) inhibition of invasion of these cells at a concentration of 100 μM that was comparable to cromolyn at the same concentration. This compound, structurally distinct from cromolyn, was successfully synthesised, purified and characterised in-house alongside 39 of its analogues. Biological screening of compound 24 and four of its analogues for anti-proliferative activity against BxPC-3 and Panc-1 pancreatic cancer cell lines showed all five compounds significantly (p < 0.0001) inhibiting proliferation in both cell lines at a concentration of 1 μM relative to the non-treated control. Hence, structurally distinct compounds that show promising inhibitory activity on the metastasis and proliferation of pancreatic cancer cells have been identified using a structure-based drug design methodology. These compounds, with further optimisation, could provide good starting points as therapeutic lead candidates for the treatment of pancreatic cancer.

Abstract:
La dystonie est une pathologie du contrôle du mouvement caractérisée par des contractions musculaires involontaires. Les causes génétiques de cette pathologie sont multiples. J’ai créé des bases de données locus spécifiques colligeant l’ensemble des diversités alléliques disponible pour 16 gènes de dystonie. L’objectif de ce travail est d’aider au diagnostic de cette pathologie et, à plus long terme et lorsque les données le permettent, d’établir des corrélations génotypes-phénotypes. Cela a été le cas pour le gène THAP1 (définissant la forme DYT6) pour lequel nous avons décrits plusieurs corrélations. J'ai recherché la mutation causale dans plusieurs familles par séquençage d'exome. Cela a permis d’identifier une famille porteuse d’une mutation prédite pathogène dans le gène ANO3 (DYT23). Une autre famille est porteuse d’une mutation dans un site d’épissage du gène ATP1A3 (DYT12) entrainant la rétention totale de l'intron 17. Pour une autres famille, un gène candidat a été identifié : ADD2 qui code l'adducine beta. Plusieurs résultats expérimentaux ont été obtenus. Tout d’abord j'ai observé des différences au niveau du cytosquelette d’actine. En effet la surexpression de la protéine sauvage provoque un comportement anormal de l’actine au niveau des fibres de stress. Par ailleurs des études de d’apprentissage par association dans un modèle C. elegans KO ADD2 ont montré un défaut de mémorisation à long-terme. Mes travaux de thèse ont permis d'approfondir les connaissances quant à la contribution de chaque gène déjà connu dans les dystonies, ainsi que d'élargir l'hétérogénéité génétique caractéristique de cette pathologie par l'identification d'un nouveau gène candidat
Dystonia is a movement control disorder characterized by involuntary muscle contractions. The genetic causes of this disease are multiple. I have created databases " loci-specific " collecting all allelic diversity available in the literature for 16 dystonia genes. The goal of this work is to to assist in the diagnosis of this disease and in the longer term, when there are sufficient data, to establish genotype-phenotype correlations. This was the case for the THAP1 gene (responsible for DYT6 dystonia) for which we have described several correlations.I searched for the disease gene in several families using exome sequencing. I identified a pathogenic mutation in the predicted gene ANO3 (DYT23) carried by one family. Another family carries a mutation in a splice site of ATP1A3 (DYT12) resulting in the total retention of intron 17. In another family a candidate gene was identified: ADD2 gene, coding beta adducin. Several functional results were obtained. First, overexpression of wild type and mutated ADD2 enabled to view differences in the actin cytoskeleton. Indeed the overexpression of the wild type protein causes abnormal behavior of actin at the level of stress fibers and at the plasma membrane. Besides, learning by association studies in a Caenorhabditis elegans model KO for ADD2 gene have shown a long-term default memory compared to the wild type. This confirms the involvement of the protein in neuronal plasticity. My thesis work led to further knowledge about the contribution of each gene already known in dystonia , as well as broaden the genetic heterogeneity characteristic of this disease by identifying a new candidate gene

Abstract:
Per la realizzazione di questo studio sono stati cercati i dati riguardanti le caratteristiche chimico-fisiche delle acque sotterranee raccolti dalle ARPA di Piemonte, Lombardia, Veneto, Friuli-Venezia Giulia ed Emilia-Romagna nel 2018. I dati ottenuti sono stati elaborati per costituire un unico database e, per ottenere questo risultato, è stato necessario omogeneizzare il più possibile i dati originali, che erano eterogenei in termini di parametri analizzati, completezza dei dati, coordinate geografiche dei punti di campionamento e limiti di rilevabilità individuati per ciascun elemento. Sono stati stabiliti sei gruppi di campioni, distinti in funzione della tipologia di acquifero in cui circolano le acque (freatico, semiconfinato, confinato) e della stagione di campionamento (primavera-estate, autunno- inverno). I campioni sono stati classificati in funzione della temperatura, del pH, della durezza e della conducibilità elettrica. Le acque sono state classificate in funzione degli ioni dominanti tramite diagrammi di Langelier-Ludwig e sono stati analizzati, tramite cartografie, i principali ioni disciolti, per valutare l’origine delle acque. Sono state valutate anche le concentrazioni di NO3-, NH4+, Fe2+, Mn2+, As3+, Crtotale, Cr VI, Ni2+, Zn2+. Le acque sono state classificate prevalentemente come Ca-HCO3 e Ca-Mg-HCO3 (90%). A livello locale sono state rilevate acque Na-HCO3, Mg-HCO3, Ca-SO4, Na-Cl e Ca-Cl. Negli acquiferi freatici sono state riscontrate contaminazioni da NO3- ed elevate concentrazioni di Na+, K+ e NH4+ attribuibili a fonti antropiche. Negli acquiferi confinati sono stati rilevati valori superiori ai limiti normativi di NH4+, Fe2+, Mn2+, As3+, riconducibili a processi naturali di degradazione della materia organica. Lo stesso è stato riscontrato per il cromo e il nichel, rilevati in concentrazioni elevate in corrispondenza di affioramenti ofiolitici. Non sono state trovate giustificazioni per gli elevati valori di Zn.

Abstract:
The objective of the International Kinetic Database (IKD) is to characterize bulk reaction rates in alkaline, neutral, and acidic minesite drainage. The IKD currently contains 307 kinetic tests from around the world, and is growing. Of the 307 tests, 185 provided leaching rates for copper and zinc. Scatterplots of these rates against pre-test parameters such as solid-phase copper and acid-base accounting failed to reveal any clear relationships. Consequently, leaching rates cannot be predicted accurately from pre-test characterization of a sample. Some correlation was noted among leaching rates, sulfate (acid) production, neutralization rate, and aqueous pH. However, the strength of these correlations was too weak to allow the accurate estimation of one parameter from another. All these observations point to the importance of kinetic testing in the assessment and prediction of mine drainage, and the inability to estimate rates prior to testing.

Image processing has been a popular research topic in recent years. In this thesis, the method proposed by us aims at utilizing various image processing tools and techniques to develop an automatic detection system which is capable of delivering accurate analysis based on the photos (taken according to the relevant specifications) of the power towers and then provides a guideline to the Taiwan Power Company (TPC) for further repair and replacement. At present, power stations owned by TPC include two major categories: (1) Power stations with just one layer of zinc coating for protection. Damages to this type of power stations are mainly corrosion; (2) Power stations with one layer of zinc coating and one layer of paint coating for protection. Damages to this type of power stations are more complex, which may include corrosion caused by rust, foaming, and cracking.

Abstract:
Due to the involvement of effective and client-friendly components (i.e. supercomputers), rapid data analysis is being accomplished. In Bioinformatics, it is expanding many areas of research such as genomics, proteomics, metabolomics, etc. Structure-based drug design is one of the major areas of research to cure human malady. This chapter initiates a discussion on supercomputing in sequence analysis with a detailed table summarizing the software and Web-based programs used for sequence analysis. A brief talk on the supercomputing in virtual screening is given where the databases like DOCK, ZINC, EDULISS, etc. are introduced. As the chapter transitions to the next phase, the intricacies of advanced Quantitative Structure-Activity Relationship technologies like Fragment-Based 2D QSAR, Multiple-Field 3D QSAR, and Amino Acid-Based Peptide Prediction are put forth in a manner similar to the concept of abstraction. The supercomputing in docking studies is stressed where docking software for Protein-Ligand docking, Protein-Protein docking, and Multi-Protein docking are provided. The chapter ends with the applications of supercomputing in widely used microarray data analysis.

Abstract:
National Maritime Research Institute of Japan (NMRI) has been developing the integrated design support tool, called “Harmonic Design Tool”, for evaluating economical / safe / environmental aspects of the offshore platform. We are also conducting the conceptual design of the offshore platforms for assessing the availability and accuracy of this design support tool. Seafloor massive sulphides (SMS) are high-grade hydrothermal deposits rich in copper, zinc and lead with a high gold and silver content. The Japanese Economic Exclusive Zone (EEZ) is well known to have high potential of SMS. Thus we decided the SMS mining as one of the most promising applications for the offshore platform technologies. Based on the published potential map of resources and the metocean database established in this project, we decided Izu-Bonin Arc as the target sea area and derived the design and operation conditions for the offshore mining platform. Then we proceeded to the basic concept such as the production rate and storage capacity, dynamic positioning system for station keeping and operation availability. This paper presents the review of the conceptual design of the offshore platform for SMS mining.

Abstract:
A two-step thermo-chemical cycle for solar production of hydrogen from water has been developed and investigated. It is based on metal oxide redox pair systems, which can split water molecules by abstracting oxygen atoms and reversibly incorporating them into their lattice. After proof-of-principle, successful experimental demonstration of several cycles of alternating hydrogen and oxygen production, and elaboration of process strategies presented in previous contributions, the present work describes a thermodynamic study aiming at the fine tuning of the redox system, at the improvement of process conditions, and at the evaluation of the potential of the process. For the redox material the oxygen uptake capability is an essential characteristic, because it is directly connected to the amount of hydrogen which can be produced. In order to evaluate the maximum oxygen uptake potential of a coating material and to be able to find new redox materials theoretical considerations based on thermodynamic laws and properties are helpful and faster than actual tests. Through thermodynamic calculations it is possible to predict the theoretical maximum output of H2 from a specific redox-material under certain conditions. Calculations were focussed on the two mixed iron oxides nickel-iron oxide and zinc-iron oxide. In the simulation the amount of oxygen in the redox-material is calculated before and after the splitting step on the basis of laws of thermodynamics and available material properties for the mixed-iron oxides used. For the simulation the commercial Software FactSage and available databases for the necessary material properties were used. The analysis showed that a maximum hydrogen yield is achieved if the regeneration temperature is raised to the limits of the operation range, if the temperature for the water splitting is lowered below 800 °C and if the partial pressure of oxygen during regeneration is decreased to the lower limits of the operational range. The increased hydrogen yield at lower splitting temperature of about 800 °C could not be confirmed in experimental results, where a higher splitting temperature led to a higher hydrogen yield. As a consequence it can be stated that kinetics must play an important role especially in the splitting step.

Desiderati, Christopher. Carli Creek Regional Water Quality Project: Assessing Water Quality Improvement at an Urban Stormwater Constructed Wetland. Portland State University, 2022. http://dx.doi.org/10.15760/mem.78.

Full text
Abstract:
Stormwater management is an ongoing challenge in the United States and the world at-large. As state and municipal agencies grapple with conflicting interests like encouraging land development, complying with permits to control stormwater discharges, “urban stream syndrome” effects, and charges to steward natural resources for the long-term, some agencies may turn to constructed wetlands (CWs) as aesthetically pleasing and functional natural analogs for attenuating pollution delivered by stormwater runoff to rivers and streams. Constructed wetlands retain pollutants via common physical, physicochemical, and biological principles such as settling, adsorption, or plant and algae uptake. The efficacy of constructed wetlands for pollutant attenuation varies depending on many factors such as flow rate, pollutant loading, maintenance practices, and design features. In 2018, the culmination of efforts by Clackamas Water Environment Services and others led to the opening of the Carli Creek Water Quality Project, a 15-acre constructed wetland adjacent to Carli Creek, a small, 3500-ft tributary of the Clackamas River in Clackamas County, OR. The combined creek and constructed wetland drain an industrialized, 438-acre, impervious catchment. The wetland consists of a linear series of a detention pond and three bioretention treatment cells, contributing a combined 1.8 acres of treatment area (a 1:243 ratio with the catchment) and 3.3 acre-feet of total runoff storage. In this study, raw pollutant concentrations in runoff were evaluated against International Stormwater BMP database benchmarks and Oregon Water Quality Criteria. Concentration and mass-based reductions were calculated for 10 specific pollutants and compared to daily precipitation totals from a nearby precipitation station. Mass-based reductions were generally higher for all pollutants, largely due to runoff volume reduction on the treatment terrace. Concentration-based reductions were highly variable, and suggested export of certain pollutants (e.g., ammonia), even when reporting on a mass-basis. Mass load reductions on the terrace for total dissolved solids, nitrate+nitrite, dissolved lead, and dissolved copper were 43.3 ± 10%, 41.9 ± 10%, 36.6 ± 13%, and 43.2 ± 16%, respectively. E. coli saw log-reductions ranging from -1.3 — 3.0 on the terrace, and -1.0 — 1.8 in the creek. Oregon Water Quality Criteria were consistently met at the two in-stream sites on Carli Creek for E. coli with one exception, and for dissolved cadmium, lead, zinc, and copper (with one exception for copper). However, dissolved total solids at the downstream Carli Creek site was above the Willamette River guidance value 100 mg/L roughly 71% of the time. The precipitation record during the study was useful for explaining certain pollutant reductions, as several mechanisms are driven by physical processes, however it was not definitive. The historic rain/snow/ice event in mid-February 2021 appeared to impact mass-based reductions for all metals. Qualitatively, precipitation seemed to have the largest effect on nutrient dynamics, specifically ammonia-nitrogen. Determining exact mechanisms of pollutant removals was outside the scope of this study. An improved flow record, more targeted storm sampling, or more comprehensive nutrient profiles could aid in answering important questions on dominant mechanisms of this new constructed wetland. This study is useful in establishing a framework and baseline for understanding this one-of-a-kind regional stormwater treatment project and pursuing further questions in the future.
