Abstract:
N-(dimethoxyphosphoryl)-1-methylpyridinium-4-carboximidate, a new carbacylamidophosphate-type compound, was synthesized and characterized by means of IR, 1H and 31P NMR and UV-Vis spectroscopies and X-ray analysis. The molecule of the synthesized compound has triclinic (P-1) symmetry, displays monomeric motif in crystal and crystalizes as solvate containing methanol molecule, which is connected to carbacylamidophosphate molecule through O(2)H(5A)–O(5) hydrogen bond. Through – stacking interactions, the molecules of the synthesized compound are linked in the chain along the a crystallographic axis. Several other intermolecular bonds connect these chains along b and c crystallographic axes. The intermolecular interactions with HH and OH contacts prevail in the crystalline structure of N-(dimethoxyphosphoryl)-1-methylpyridinium-4-carboximidate, the contribution of planar stacking CC contacts being equal to 4.1%. The synthesized compound was found to be well soluble in water. By using computer program PASS, we established that the synthesized substance is likely can exhibit 18 types of biological activity in experiment.

Abstract:
Background Precise determination of conformational epitopes of neutralizing antibodies represents a key step in the rational design of novel vaccines. A powerful experimental method to gain insights on the physical chemical nature of conformational epitopes is the selection of linear peptides that bind with high affinities to a monoclonal antibody of interest by phage display technology. However, the structural characterization of conformational epitopes from these mimotopes is not straightforward, and in the past the interpretation of peptide sequences from phage display experiments focused on linear sequence analysis to find a consensus sequence or common sequence motifs. Results We present a fully automated search method, EpiSearch that predicts the possible location of conformational epitopes on the surface of an antigen. The algorithm uses peptide sequences from phage display experiments as input, and ranks all surface exposed patches according to the frequency distribution of similar residues in the peptides and in the patch. We have tested the performance of the EpiSearch algorithm for six experimental data sets of phage display experiments, the human epidermal growth factor receptor-2 (HER-2/neu), the antibody mAb Bo2C11 targeting the C2 domain of FVIII, antibodies mAb 17b and mAb b12 of the HIV envelope protein gp120, mAb 13b5 targeting HIV-1 capsid protein and 80R of the SARS coronavirus spike protein. In all these examples the conformational epitopes as determined by the X-ray crystal structures of the antibody-antigen complexes, were found within the highest scoring patches of EpiSearch, covering in most cases more than 50% residues of experimental observed conformational epitopes. Input options of the program include mapping of a single peptide or a set of peptides on the antigen structure, and the results of the calculation can be visualized on our interactive web server.

Abstract:
SinR is a transcription factor which controls expression of stress tolerance sin genes related to alternate development processes under stress condition. Identification of genome wide SinR-box motif and their regulated genes has not been worked out yet in Bradyrhizobium japonicum. For this, a weight matrix of 9 bp was developed from the known promoter sequences of Bacillus subtilis, which was then used for genome wide identification of co-regulated genes. The methodology first involves phylogenetic footprinting of SinR regulated genes and then construction of scoring matrix through ‘Consensus’ and confirmation through MEME & D-Matrix tools. Genomic prediction was done through ‘Patser’ program and confirmation through ‘PossumSearch’ program in Linux system. Results showed that all the 371 predicted genes belongs to 9 different functional classes, in which 221 found in operons with more than 80% Sin-box motif similarity. Similar approach can be used in other bacteria to explore hidden genomic regulatory network.

Abstract:
Abstract Motivation Increasing evidence has shown that nucleotide modifications such as methylation and hydroxymethylation on cytosine would greatly impact the binding of transcription factors (TFs). However, there is a lack of motif finding algorithms with the function to search for motifs with modified bases. In this study, we expand on our previous motif finding pipeline Epigram to provide systematic de novo motif discovery and performance evaluation on methylated DNA motifs. Results mEpigram outperforms both MEME and DREME on finding modified motifs in simulated data that mimics various motif enrichment scenarios. Furthermore we were able to identify methylated motifs in Arabidopsis DNA affinity purification sequencing (DAP-seq) data that were previously demonstrated to contain such motifs. When applied to TF ChIP-seq and DNA methylome data in H1 and GM12878, our method successfully identified novel methylated motifs that can be recognized by the TFs or their co-factors. We also observed spacing constraint between the canonical motif of the TF and the newly discovered methylated motifs, which suggests operative recognition of these cis-elements by collaborative proteins.

Abstract:

This master thesis consists of three parts. The first part contains a summary of what is needed to understand a X.509 parser that I have created, a discussion concerning the technical problems I encountered during the programming of this parser and a discussion concerning the final version of the parser. The second part concerns a comparison I made between the X.509 parser I created and a X.509 parser created"automatically"by a compiler. I tested static memory, allocation of memory during runtime and utilization of the CPU for both my parser (MP) and the parser that had a basic structure constructed by a compiler (OAP). I discuss changes in the parsers involved to make the comparison fair to OAP, the results from the tests and when circumstances such as time and non-standard content in the project make one way of constructing a X.509 parser better than the other way. The last part concerns a WTLS parser (a simpler kind of X.509 parser), which I created.

La preorganització electrostàtica del centre actiu s'ha postulat com el mecanisme genèric de l'acció dels enzims. Així, alguns residus "estratègics" es disposarien per catalitzar reaccions interaccionant en una forma més forta amb l'estat de transició, baixant d'aquesta manera el valor de l'energia dactivació g cat. S'ha proposat que aquesta preorientació electrostática s'hauria de poder mostrar analitzant l'estabilitat electrostàtica de residus individuals en el centre actiu.
Ras es una proteïna essencial de senyalització i actúa com un interruptor cel.lular. Les característiques estructurals de Ras en el seu estat actiu (ON) són diferents de les que té a l'estat inactiu (OFF). En aquesta tesi es duu a terme una anàlisi exhaustiva de l'estabilitat dels residus del centre actiu deRas en l'estat actiu i inactiu.
The electrostatic preorganization of the active site has been put forward as the general framework of action of enzymes. Thus, enzymes would position "strategic" residues in such a way to be prepared to catalyze reactions by
interacting in a stronger way with the transition state, in this way decreasing the activation energy g cat for the catalytic process. It has been proposed that
such electrostatic preorientation should be shown by analyzing the electrostatic stability of individual residues in the active site.
Ras protein is an essential signaling molecule and functions as a switch in the
cell. The structural features of the Ras protein in its active state (ON state) are different than those in its inactive state (OFF state). In this thesis, an exhaustive analysis of the stability of residues in the active and inactive Ras active site is performed.

Abstract:
The field of knowledge discovery is concerned with the theory and processes involved in the representation and extraction of patterns or motifs from large databases. Discovered patterns can be used to group data into meaningful classes, to summarize data, or to reveal deviant entries. Motifs stored in a database can be brought to bear on difficult instances of structure prediction or determination from X-ray crystallography or nuclear magnetic resonance (NMR) experiments. Automated discovery techniques are central to understanding and analyzing the rapidly expanding repositories of protein sequence and structure data. This chapter deals with the discovery of protein structure motifs. A motif is an abstraction over a set of recurring patterns observed in a dataset; it captures the essential features shared by a set of similar or related objects. In many domains, such as computer vision and speech recognition, there exist special regularities that permit such motif abstraction. In the protein science domain, the regularities derive from evolutionary and biophysical constraints on amino acid sequences and structures. The identification of a known pattern in a new protein sequence or structure permits the immediate retrieval and application of knowledge obtained from the analysis of other proteins. The discovery and manipulation of motifs—in DNA, RNA, and protein sequences and structures—is thus an important component of computational molecular biology and genome informatics. In particular, identifying protein structure classifications at varying levels of abstraction allows us to organize and increase our understanding of the rapidly growing protein structure datasets. Discovered motifs are also useful for improving the efficiency and effectiveness of X-ray crystallographic studies of proteins, for drug design, for understanding protein evolution, and ultimately for predicting the structure of proteins from sequence data. Motifs may be designed by hand, based on expert knowledge. For example, the Chou-Fasman protein secondary structure prediction program (Chou and Fasman, 1978), which dominated the field for many years, depended on the recognition of predefined, user-encoded sequence motifs for α-helices and β-sheets. Several hundred sequence motifs have been cataloged in PROSITE (Bairoch, 1992); the identification of one of these motifs in a novel protein often allows for immediate function interpretation.

Abstract MinnSketch© is a new conceptual design package for the generation of planar mechanisms. This program is implemented in C and runs in an X/Motif graphic environment. MinnSketch allows users to intuitively construct a mechanism from scratch and to rapidly develop the conceptual model to a workable solution. The purpose of developing this program was to create an intuitive design tool, so the user interface was designed to closely model the real-world environment. By directly manipulating the graphic conceptual model intuitively with the aid of the feedback from the simulation and analysis results, users can thoroughly understand their designs and thus can increase their productivity.

Full text
Abstract:
An Excel© spreadsheet lines development program has been written for a home computer and is available to conference attendees. The program utilizes B-Spline parametric formulations for planar curve definition of the traditional hull lines: body, waterlines and buttocks. The user establishes the basic hull outline, in BSpline curves, by inputting bow and stern overhangs, freeboard at selected points, the draft of the canoe body at selected points, the beam on deck at selected points, and the maximum beam at the waterline. By judicious selections the user will see the resulting hull outline in profile and plan views, and can easily adjust these inputs to gain the desired hull outline. The user works with actual points on the hull rather than B-Spline vertices. The hull lines are then developed by the Excel program which establishes the hull form defined by the above outlines and satisfying inputs of the conventional hull form parameters: Center of Buoyancy, (Lcb) Center of Floatation, (Lcf) Prismatic Coefficient, (Cp), Maximum Section Coefficient, (Cm) and the Water-plane Coefficient, (Cwp). The lines development is accomplished in two steps. First, the user employs the Excel Solver to establish a waterline, and Sectional Area curve that satisfy the above parameters. The program accomplishes this by varying the draft at stations two and eight, which adjusts the shape of the center-plane curve without changing the draft, Tc. The solver ensures a “fair” waterline by minimizing the “bending” criterion of the waterline: that is, by minimizing the sum of the squares of d2y/du2 and d2x/du2. Here, y and x are defined by B-Spline formulations in the parameter “u”. The vertices of the B-Spline functions are varied by the Excel Solver to find the minimum bending criterion. Second, with the Section Area and waterline beam established for each station, the program establishes the shape of each station body curve which satisfies the section area, draft, freeboard and beams on deck and waterline. Fairness is again established by minimizing the “bending” criterion. Since there are no section areas for stations 10 and the transom, a scheme for constructing a transomgeometrically similar to station 9.5 is provided. Station 10 is established by fairing to the transom. The program can establish a round bottom hull in about a minute and a half after the input parameters are entered. It is essential however that the hull form parameters be selected judiciously. Clearly Lcb and Lcf must be compatible, and the hull outline must be reasonable in order to gain a fair hull. In this regard the user is provided with automatic input of six different hull shapes that provide good starting points for a design effort. Thus, in a matter of minutes the user can examine an alternate hull shape while keeping selected hull form parameters constant.

Abstract This study proposes an effective and feasible method that improves the existing methods for disassembly. The elements of three dimensional interference matrices in the directions of x, y and z axes are considered as the low bit, middle bit and high bit, respectively, for the elements of the proposed disassembly matrix in the binary system. By using the Boolean operation and the deep-first-search method, the algorithm is developed and a software program is generated to create all of the possible disassembly sequences and directions of components in the tree diagram. With the grades for change of the disassembly directions, the optimum disassembly sequences can be determined. This disassembly matrix not only can help disassemble the disposed devices but also can evaluate the potential products during design.

Abstract:
This paper presents a computational and visualization tool kit for the numerical modeling of 3-D Marangoni and/or magnetically-driven turbulent flows in droplets under normal and/or microgravity conditions. The computational part involves the finite element solution of steady-state and transient 3-D Marangoni flows in electrically levitated droplets and the higher order finite difference method for the direction numerical simulation of tubulences in electromagnetically levitated droplets. Both the electrically and magnetically droplets have been used for study of fundamentals governing solidification processing in normal and mcrio gravity. The visualization part is developed based on the UNIX/X-motif platform and on the advanced algorithms for multi-dimensional computer graphics. The visualization tool kit employs the algorithms for data retrieving, partitoning, sorting and searching algorithms, and 3-D/2-D object clipping. An efficient algorithm used for plane and body cutting and particle tracing is presented. The mathematical formulation used in developing the above computational tool kit, including computational and differential geometry, is also discussed. Examples are given to illustrate the effectiveness and efficiency of the tool kit as applied to the numerical simulation and computer visualization of complex steady state and transient three-dimensional Marangoni and turbulent magnetically driven flows in free droplets.

Abstract:
Cryosurgery is also called as cryoablation or cryoleision. The third generation of cryo-machine use argon gas for cooling and helium for rewarming to destroy cancer cells. The probes may be put into the tumor during surgery or through the skin (percutaneously). After cryosurgery, the frozen tissue thaws and is either naturally absorbed by the body (for internal tumors), or it dissolves and forms a scab (for external tumors). The main purpose of this paper is to establish a preliminary computer assisted simulation in prostate tumor cryosurgery. A radiologist and an urologist in a medical center in addition to the engineering specialist from the university participated in this interdisciplinary research program. The first step of this simulation protocol is to trim hundreds of two-dimensional medical imaging photos from a patient through the imaging reconstructive software into building a three-dimensional solid modeling. The image data for each patient can be obtained from the x-ray computed tomography (CT), or magnetic resonance imaging (MRI) in the imaging department of hospital. It has successfully built up the related knowledge to overcome the complicacy between the medical imaging modalities and engineering graphic solid modeling with high resolution. It is worthy to mention here that the present solid modeling of prostate can demonstrate the variable diameters and courses of the prostate urethra in vivo. The second step focuses on thermal calculation. So far, there has been no existing commercial software for the specific purpose of the bioheat transfer problem. Hence, user subroutines must be added to the existing commercial software to simulate the clinical situation of cryosurgery. For example, the occurrence of phase change during some specified temperature range and the latent heat of fusion are also incorporated into bio-heat transfer model. It has successfully incorporated bioheat transfer model into the software program to fit the reality in thermal medicine. The third step supplies the data and knowledge concerned with the position of a tumor and the related mechanism of metabolism of living tissue and vessels. The number of probes, the position of each probe, and the operating time of each probe will be explored to ensure a complete killing of the tumor tissue while saving as much healthy surrounding tissue as possible. In this study, the three-dimensional transient temperature distributions based on cryosurgery for prostate tumors have been performed for several cases to find the optimal operating conditions. Different cryoprobes with different freezing time are considered to find the temperature distribution. The simulation results for cryosurgery of prostate tumors will be supplied for practicing physicians as reference to greatly improve the effectiveness of cryosurgery.

Abstract:
In this work it is reviewed the variational approach for some Transport Problems. Let X be a convex domain in Rn, and V a compact set. For that, it is considered the following equation: ∂ψ∂t(x,v,t)+v·∇ψ(x,v,t)+h(x,μ)ψ(x,v,t)==∫Vk(x,v,v′)ψ(x,v′,t)dv′+q(x,v,t)(1) where x represents the spatial variable in a domain D, v an element of a compact set V, Ψ is the angular flux, h(x,v) the collision frequency, k(x,v,v’) the scattering kernel function and q(x,v) the source function. It is put the attention in the construction of the quadratic functional J which appears in variational approaches for transport theory (for example, the Vladimirov functional). Some properties of this functional in a proper functional framework, in order to determine the minimum for J are considered. First, the general formulation is studied. Then an algorithm is given for minimizing the functional J for two remarkable problems: spherical harmonic method and spectral collocation method. A program associated to this algorithm is worked in a computer algebraic system, and also was depeloped a version in a high level language.

Abstract:
In order to detect hypercoagulable state due to the increase or decrease of coagulation factors and inhibitors concentrations or the presence of active coagulation factors or tissue factor in plasma, highly sensitive automated methods were developed using fluorogenic substrate for thrombin. Coagulability of human plasma was measured by mixing 3 yl of plasma with Thromborel S (TF), calcium and Boc-Val-Pro-Arg-MCA(MCA) (Fluorogenic PT, FPT). FPT of normal plasma was shortened by the addition of purified X or VII (Final conc. 1-5 U per ml), and of thrombin (0.3-1 ng) or Xa (10500 pg). Factors VII and X contents in plasma were measured by mixing 3 yl of diluted plasma with each factor deficient plasma, TF, calcium and MCA in which 10 %-800 % of each factor was quantitatively measured. TF and Xa were measured by mixing with XII or X deficient plasma, phospholipid, calcium and MCA. By this method, 5-500 pg of Xa or 1-1000 units of TF (assuming that one vial of Thromborel S contains 2,000,000 U TF per ml) was quantitatively measured. All the experiments were performed using a centrifugal autoanalyzer (Cobas Bio) with FIA module. The reaction time to reach 0.1 relative fluorescence was calculated by a computer using a program developed by us.These automated methods were applied to examine the hypercoagulability of plasmas from patients with cerebral infarction. Sixty five samples out of 75 showed shorter FPT than control plasma. Xa was detected with the conc. of 3-13 ng Xa per ml. FPT of patient plasmas correlated with Xa content (r=0.70) and X (r=0.63). Xa activity of patient plasma was eluted in the same peak as purified X on gel-filtration of Sephacryl S-200 column and completely inhibited by anti X rabbit IgG. Xa activity was also found in normal serum. The conventional PT or chromogenic PT methods are sensitive to hypocoagulable state but not to hypercoagulab le state. The present automated methods were proved to be sensitive to hypercoagulable state and demonstrated that the presence of Xa or the increase of X concentration in plasma contributes in part to the hypercoagulable state of cerebral infarction.

Abstract:
Abstract Generalized design sensitivity analysis of constrained dynamic systems is a computationally intensive process that is well-suited for implementation on a modern supercomputer. A matrix oriented method for design sensitivity analysis, based on direct differentiation, is developed. An algorithm based on this development was implemented in a computer code which was then run on a Cray X-MP supercomputer. The implementation attempts to make full use of the vectorization capabilities of this machine. The numerical examples that were run on this implementation were compared with results presented in the literature in order to verify the program and to assess its computational performance. The results show that the use of supercomputers for performing design sensitivity analysis of dynamic systems using this method produces a dramatic reduction in the computing time; it is anticipated that this will make the optimization of very large-scale dynamic systems computationally viable.

Abstract:
The presence of High Molecular Weight kininogen (HMWK) was demonstrated in cultured human endothelial cells (EC) by immunofluorescence techniques. Using an enzyme linked immunosorbent assay a concentration of 58 ng HMWK/10 cells was determined. Immunoprecipitation studies performed with lysed metabolically labelled endothelial cells and mono-specific antisera directed against HMWK suggested that HMWK is not synthesized by the endothelial cells. Endothelial cells cultured in the presence of HMWK-depleted serum did not contain HMWK. This, suggests that endothelial cells can internalize HMWK. Using 125I-HMWK it was demonstrated that cultured endothelial cells bind HMWK in a time-dependent, specific and saturable.way. The cells were found to internalize 125I-HMWK, since I-HMWK was detected in solubilized endothelial cells after the cell bound 125I-HMWK had been eluted with dextran sulphate.The binding of I-HMWK required the presence of zinc ions. Optimal binding of 125I-HMWK was observed at 50 μM Zn++ . Calcium ions inhibited the Zn++ dependent binding of 125I-HMWK |25EC. In the presence of 3 mM CaCl2 the total binding of 125I-HMWK was significantly decreased, and a .concentration of 200 μM Zn++ was Required for the binding of 125I-HMWK to thecells. Higher,. Ca concentrations did not further decrease the binding of 125I-HMWK. Analysis of tl^e binding data by the ligand computer program indicated 3.2 x 10 binding sites per cell for HMWK with a Kd of 35 nM at 50 μM ZnCl2 and 1 mM CaCl2. Specify binding of HMWK did also occur at physiological plasma Zn++ concentrations. Half maximal binding was observed at HMWK concentrations of ± 105 nM at 10 μM ZnCl2 and 45 nM at 25 μM ZnCl2. The HMWK binding sites were saturatecT at HMWK concentrations of 130 nM with 1.6 x 10 molecules of HMWK bound per cell and at 80 nM with 2.8 x 10 molecules of HMWK bound per cell at 10 and 25 pM ZnCl2 respectively. These results suggest that at physiological zinc, calcium and HMWK concentrations the HMWK binding sites on the endothelial cell are saturated. The presence of HMWK on the endothelial cell surface may play a role in the initiation of the intrinsic coagulation pathway. M ZnCl2 and 45 nM at 25 μM ZnCl2.
