Computational diagnostics based on proteomic data- review on approaches and algorithms
Sreevatsa A.N.,Badrunnisa S.,Shaukath Ali M.,Vinitha R Pai
International Journal of Bioinformatics Research , 2010,
Abstract: Protein identification using mass spectrometry is an indispensable tool for proteomics which inrecent days has evolved to give better understanding of the biology of cell and its functioning. Proteomicshas wide application in diagnosing diseases such as cancer, Alzheimer’s disease etc. The data obtainedfrom the diagnostic tools like LC-MS is to be interpreted accurately so as to obtain the correct qualitative andquantitative information about the peptides present in the biological sample. Such interpretation requires andexhaustive knowledge and review about different tools that can be employed and their comparison. Thisarticle focuses on comparison of different proteomic tools available for the MS data processing andinterpretation. The accuracy demanded during protein identification can be fulfilled by tag basedapproaches, than PMF or PFF systems. Although, there is a need of standardized matrices for thecomparison of the protein identification tools, identifying the single best package for each application fromthe available literature is at present extremely difficult as each package has its own advantage over other.The datasets and thresholds used in these kinds of comparisons have a critical importance on the outcomeof such experiments, and that the high variability in machine and experimental setups complicates analysis.The state of data standards and lack of benchmarks therefore makes it difficult to make an effectivecomparison. While the increasing availability of data in public repositories and tightening standards will nodoubt ameliorate the problem, until this basic benchmarking problem is overcome, no single package orapproach can conclusively be declared to outperform all others, expect, perhaps, in the specificcircumstances used in particular studies.

Abstract: Rainbow trout (Onchorhynchus mykiss) are an important aquaculture species yet there are few diagnostic tools available to assess their health. There is little published information regarding age-related changes in blood values of juvenile fish. It is important to evaluate juvenile fish, as this is the time they are raised in aquaculture settings. Determining age-related changes in the blood values of fishes would further develop clinical pathology as a diagnostic tool, enhancing both fish medicine and the aquaculture industry. The results of standard hematology and clinical chemistry analysis were evaluated in juvenile rainbow trout at 4, 6, 9, 15 and 19 months of age. Values for PCV and RBC indices were significantly lower, and plasma protein concentration was significantly higher in younger fish. Total WBC and lymphocyte counts were significantly higher in fish at 6 and 9 months of age, while neutrophil and monocyte counts were higher at 6, 9 and 15 months. Eosinophil counts were significantly higher in 9 month old fish. The majority of hematologic values fell within previously established reference intervals, indicating that only slight modification to the intervals is necessary for evaluating hematologic results of rainbow trout at different ages. The following analytes deviated sufficiently from adult reference intervals to warrant separate reference values: plasma protein concentration at 4 months, WBC and lymphocyte counts at 15 and 19 months, and thrombocyte-like-cells at 9 months of age. Values for most biochemical analytes were significantly different among age groups except for creatinine and potassium concentrations. Comparisons with reference intervals were not made for biochemical analytes, because established reference intervals were not available.

Abstract: The asymmetric unit of the title compound, C19H19ClO4, contains two independent molecules. The dihedral angles between the benzene rings are 63.41 (8) and 61.41 (9)°. Adjacent molecules of different types are interconnected in pairs through π–π interactions between their central benzene rings [centroid–centroid separation = 3.801 (2) , interplanar spacing = 3.605 (2) , centroid shift = 1.204 (2) ]. Finally, C—H...O hydrogen bonds link these dimers into bilayers parallel to (100).
Laplace Transform Method for Unsteady Thin Film Flow of a Second Grade Fluid through a Porous Medium  [PDF]
M. Ali, M. Awais
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.53017
Abstract:

In this article, we have effectively used the Numerical Inversion of Laplace transform to study the time-dependent thin film flow of a second grade fluid flowing down an inclined plane through a porous medium. The solution to the governing equation is obtained by using the standard Laplace transform. However, to transform the obtained solutions from Laplace space back to the original space, we have used the Numerical Inversion of Laplace transform. Graphical results have been presented to show the effects of different parameters involved and to show how the fluid flow evolves with time.

Optimal Convergence Analysis for Convection Dominated Diffusion Problems  [PDF]
M. A. Mohamed Ali
Journal of Applied Mathematics and Physics (JAMP) , 2013, DOI: 10.4236/jamp.2013.13004
Abstract:

In classical mixed finite element method, the choice of the finite element approximating spaces is restricted by the imposition of the LBB consistency condition. The method of H1-Galerkin mixed finite element method avoids completely the imposition of such a condition on the approximating spaces. In this article, we discuss and analyze error estimates for Convection-dominated diffusion problems using H1-Galerkin mixed finite element method, along with the method of characteristics. Optimal order of convergence has been achieved for the error estimates of a two-step Euler backward difference scheme.

Rock Slope Stability Problems in Wadi Quaz-Dam Site No. 2, Jeddah-Saudi Arabia  [PDF]

World Journal of Engineering and Technology (WJET) , 2015, DOI: 10.4236/wjet.2015.34026
Abstract: The present investigation deals with the engineering geological studies of soil and rock masses in the Wadi Quaz area-Dam No. 2, East of Jeddah. Wadi Quaz area-Dam No. 2, East of Jeddah, Saudi Arabia often faces floods during rainy seasons, so it is so urgent to investigate the area before building any dam or preventing water from flow. Preventing water from flow will produce new dangerous factors such as uplift force which may cause the dam failure. To have a better understanding of the factors that may affect the slope stability, many rock slope locations are observed in detail to assess the effect of discontinuities formed in the rock masses. Fieldwork and Laboratory tests were carried out on soil and rocks. Soils included identification of soil type using unified soil classification system, permeability, water content and field density were done for soils. Rocks include identification of physical and mechanical properties such as: rock type, degree of weathering, rock strength, RQD, joint spacing measurements, and geometric properties (Dip, and Dip direction). Different methods were used to evaluate the potential failure in the studied area depending on rock mass rating and slope stability analysis. The well-known classification of rock masses titled Rock Mass Rating system [1] was used for categorizing the rock masses in the studied area besides slope mass rating [2] which would help to estimate the rock stability. The kinematical analysis was applied to investigate the potential failure mode which might occur in the dam abutments. This paper will provide the stability of dam abutments in both summer season and winter season besides general estimation of the seepage problems related to the soil and according to its permeability.

Afaf M. Ali
Optics and Photonics Journal (OPJ) , 2017, DOI: 10.4236/opj.2017.76011
Abstract: Changes in the different structural parameters of iPP fibers during the dynamically cold drawing process were characterized. Using the dynamic mechanical cold drawing device attached to Fizeau interference system all the optical and structural properties can be measured. With the aid of this device the effect of the strain rate on the different structure properties was measured. The molecular orientations, molecular polarizability, molar reflectivity and shrinkage stress were measured. Reorientation of the molecules led to a significant variations in the measured structure properties of the drawn iPP fibers during applying the external tension.

Faten M. Ali Zainy
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2017, DOI: 10.4236/jcdsa.2017.74030
Abstract: The present study reports the content of 14 heavy metals (Al, Fe, Ti, Ag, As, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn) in twenty-two (n = 22) lipstick products of imported and locally manufactured at the local market in Jeddah, Saudi Arabia using Inductivity Coupled Plasma-Optical Emission Spectrophotometer (ICP-OES). The overall average contents of Al, Fe, Ti, Ag, As, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn were 3131.18 ± 0.09, 9642.92 ± 0.079, 46.59 ± 0.109, 0.545 ± 0.009, 2.041 ± 0.024, 1371.439 ± 0.085, 0.134 ± 0.008, 4.242 ± 0.02, ND, 3.934 ± 0.03, 19.712 ± 0.012, 20.196 ± 0.056, 0.725 ± 0.012, and 858.666 ± 0.083 μg/g, respectively. The correction coefficient of the results is up to 0.9995, showing an excellent linear relationship between metal concentrations in samples. The results also revealed that, the total concentrations of toxic metals in various samples ranged from 1201.35 - 60,800.36 μg/g. The dark-colored lipstick samples 1B, 2B, 3B, 4B, 5B, 7B, B8, 9B, and 10B revealed high content of total toxic metals compared to the light-colored lipstick samples 1A, 2A, 3A, 4A, 4C, 5A, 7A, 8A, 9A, and 10A. The concentrations of Al, Fe, Ba, and Zn in the samples within each class under investigation are relatively high whereas the concentrations of Ag, As, Cd, Co, Cu, and Pb are lowest; and Ti, Mn, and Ni contents were below 100 μg/g. Chromium was not detected in any sample. Since no safe limits for most of these metals relating to cosmetic products are available in Saudi Arabia, it is hard to ascertain whether the values obtained in this study are relatively high or low. Prolonged use of products containing these elements may pose a threat to human health and could damage the environment.

Abstract: If G is a connected graph, the distance d (u,v) between two vertices u,v ∈ V(G) is the length of a shortest path between them. Let W = {w1, w2, ..., wk} be an ordered set of vertices of G and let v be a vertex of G . The repre-sentation r(v|W) of v with respect to W is the k-tuple (d(v,w1), d(v,w2), …, d(v,wk)). . If distinct vertices of G have distinct representations with respect to W , then W is called a resolving set or locating set for G. A re-solving set of minimum cardinality is called a basis for G and this cardinality is the metric dimension of G , denoted by dim (G). A family ? of connected graphs is a family with constant metric dimension if dim (G) is finite and does not depend upon the choice of G in ?. In this paper, we show that dragon graph denoted by Tn,m and the graph obtained from prism denoted by 2Ck + {xkyk} have constant metric dimension.

Abstract: Objectives: To review the pattern of thyroid tumor, demographic data of the patients, sensitivity, and specificity of fine needle aspiration cytology; Materials and Methods: This is a retrospective analysis of patients who underwent total or near-total thyroidectomy at King Fahad Hospital of the University between 1982 and 2008. Data were analyzed for demographic characteristics, type of thyroid tumors, Fine Needle Aspirations Cytology (FNAC) yields and surgical complications; Results: A total of 143 patients with thyroid tumors underwent throidectomy. Their median age was 37.5 years. Females were predominantly affected (81%) with female to male ratio of (4:29). Thyroid carcinoma accounted for (75%) while benign tumors for (25%). The most common thyroid epithelial cancer was papillary type (74%) and was limited to thyroid tissues in almost two third of cases. Non-epithelial cancer in the form of thyroid lymphoma accounted for (4.89%) of the cases. FNAC sensitivity was 56% and specificity 92%. Surgical complications occurred in 18% of the patients; Conclusions: The commonest malignant thyroid cancer was papillary carcinoma. Thyroid cancer was more common in females. FNAC is highly accurate to confirm thyroid cancer but less sensitive in this study. Surgical complications were relatively minimal.
