Abstract: We describe here a one month old female child with several dysmorphic features and with a de novo analphoid supernumerary marker chromosome only in cultured skin fibroblast cells and not in lymphocytes. The marker was characterized as analphoid inversion-duplication 3q25.33-qter by oligo array comparative genomic hybridization (aCGH) and fluorescence in situ hybridization (FISH) studies. The final skin fibroblast karyotype was interpreted as 47,XX,+der(3).ish inv dup(3)(qter-q25.33::q25.33-qter)(subtel 3q+,subtel 3q+) de novo.In addition to the eight reported cases of analphoid inversion-duplication 3q supernumerary marker in the literature, this is yet another case of 3q sSMC with a new breakpoint at 3q25.33 and with varying phenotype as described in the case report. Identification of more and more similar cases of analphoid inversion-duplication 3q marker will help in establishing a better genotype-phenotype correlation. The study further demonstrates that aCGH in conjunction with routine cytogenetics and FISH is very useful in precisely identifying and characterizing a marker chromosome, and more importantly help in providing with an accurate genetic diagnosis and better counseling to the family.Small supernumerary marker chromosomes occur in 0.075% of unselected prenatal cases and in 0.044% of consecutively studied postnatal cases, and majority of them are de novo in origin [1-4]. Phenotype of individuals with de novo sSMC vary from normal to extremely mild or severe, depending on the chromosomal region involved and the euchromatic content present [5-7]. Although a number of reports describe the occurrence of a variety of sSMC for nearly all the chromosomes, the number for each type is not large enough to suggest a good genotype-phenotype correlation for a given sSMC, except for inv dup(15) and inv dup(22) where the phenotypic consequences are well described [6,8-10]. We describe here the phenotype and corresponding molecular cytogenetic results of a child with

Green recycling of chicken feather and sheep wool using the partially purified alkaline protease from Bacillus circulans L.  [PDF]
Eman Fathi Sharaf, Khadijah Al-Fadel
Natural Science (NS) , 2013, DOI: 10.4236/ns.2013.56A004
Abstract:

The previously optimized crude alkaline protease from the haloalkaliphilic Bacillus circulans L. was partially purified using ammonium sulphate fractionation and dialysis. The best specific activity (27.7 U/mg protein) was obtained at 80% saturation. The optimum reaction temperature and reaction pH was 47and 9, respectively. The enzyme activity was enhanced with Ca and K chlorides but suppressed with HgCl2 and EDTA. The partially purified protease showed strong proteolytic activity on sheep wool and chicken feather. Also, the enzyme was compatible with the common detergent Tide and could improve its cleaning power in removing blood stain. These findings support the application of the present alka-line protease in biotechnological industries.

Two-Temperature Generalized Thermoelasticity without Energy Dissipation of Infinite Medium with Spherical Cavity Thermally Excited by Time Exponentially Decaying Laser Pulse  [PDF]
Eman A. N. Al-Lehaibi
Modeling and Numerical Simulation of Material Science (MNSMS) , 2015, DOI: 10.4236/mnsms.2015.54006
Abstract: This work is dealing with two-temperature generalized thermoelasticity without energy dissipation infinite medium with spherical cavity when the surface of this cavity is subjected to laser heating pulse. The closed form solutions for the two types of temperature, strain, and the stress distribution due to time exponentially decaying laser pulse are constructed. The Laplace transformation method is employed when deriving the governing equations. The inversion of Laplace transform will be obtained numerically by using the Riemann-sum approximation method. The results have been presented in figures to show the effect of the time exponentially decaying laser pulse and the two temperature parameter on all the studied fields.
Linezolid versus Vancomycin for the Treatment of Methicillin-Resistant Staphylococcus aureus in Hospital-Acquired, Ventilator-Associated, and Healthcare-Associated Pneumonia at Tertiary Care Hospital  [PDF]
Eman Mohammad Hamdan, Majda AL-Attas
Advances in Infectious Diseases (AID) , 2017, DOI: 10.4236/aid.2017.71002
Abstract: Aim: To evaluate morbidity and mortality rate, clinical cure rate and cost of linezolid versus vancomycin in patients who have hospital-acquired pneumonia (HAP), ventilator-associated pneumonia (VAP) or Healthcare-associated pneumonia (HCAP) caused by methicillin-resistant Staphylococcus aureus (MRSA). Methods: Retrospective analysis data. Data were collected for adult patients admitted to King Faisal Specialist Hospital and Research Centre-Jeddah (KFSH & RC-J) from January 2010 to May 2015. Method: A total of 88 patients with HAP, VAP and HCAP caused by MRSA treated with vancomycin (IV) or linezolid (IV or PO) either as empirically or directed therapy ≥ 7 days. They are retrospectively evaluated and analyzed. The primary end points are morbidity and mortality rate as well as clinical cure rate. The secondary end point is the cost analysis for each medication. Results: A total of 40 patients (ICU, n = 13 (32.5% and non ICU, n = 27 (67.5%)) were included in the study. Among vancomycin, n = 21 (52.5%); age (54.95 ± 18.255) and linezolid, n = 19 (74.5%); age (48.684 ± 25.593), there was no statistical differences in mortality and morbidity rate (P = 0.375). Clinical cure rate (fever improvement, 12 (57.1%) vs 12 (63.2%); P = 0.698, leukocytosis improvement, 15 (71.4%) vs 14 (73.7%); P = 0.873, purulent sputum improvement, 6 (28.6%) vs 4 (21.1%); P = 0.429, dyspnea improvement, 8 (38.1%) vs 3 (15.8%); P = 0.115,cough improvement 4 (19.0%) vs 4 (21.1%); P = 0.592, microbiological eradication of MRSA from sputum culture, 2 (9.5%) vs 6 (31.6%); P = 0.089 and improvement of radiographic finding (pulmonary infiltration), 17 (81.0%) vs 16 (84.2%); P = 0.559) of vancomycin vs linezolid, respectively. The cost analysis in the treatment of MRSA pneumonia with linezolid is statistical significantly higher than vancomycin. The mean cost of vancomycin = 185.9143 SR and of linezolid = 4547.3684 SR (P < 0.0001) of one patient during the treatment period. Conclusion: There are no statistical differences in mortality and morbidity rate and clinical cure rate between linezolid and vancomycin in the treatment of MRSA in HAP, VAP, and HCAP. However, the cost of linezlid is significantly higher than vancomycin during the treatment period of one patient.
An Application of Gas Chromatography-Mass Spectrometry (GC-MS) Fast Automated Scan/SIM Type (FASST) in Determining the Preservative Levels in Foods  [PDF]
Eman Wajeh Ammen, Raghad Al-Salhi
American Journal of Analytical Chemistry (AJAC) , 2017, DOI: 10.4236/ajac.2017.85023
Abstract: The preservatives used in food products are strictly monitored and regulated. The present study aims to imply a sensitive and reliable analytical method to quantify two classes of preservatives (i.e. carboxylic acid and phenolic compounds) in food by means of gas chromatography-mass spectrometry (GC-MS), aimed at monitoring the products available within the local stores. Target analytes were derivatized via aqueous-phase isobutyl chloroformate-mediated reaction followed by dispersive liquid-liquid microextraction (DLLME) method. The quantity and quality determination of the studied samples were assured by performing FASST approach in a single run GC-MS analysis. The combination of standard addition method with sample dilution compensated the effect of sample matrix on the quantitative determination of the tested preservatives in the examined samples. The concentrations of sorbic acid (SA) were 210 μg/mL and 1000 μg/mL in soft drink and sauces samples, respectively. On the other hand, sodium benzoate (226 μg/mL) was only found in soft drink, whereas, no parabens were detected in any samples collected from the local stores.

Journal of Signal and Information Processing (JSIP) , 2013, DOI: 10.4236/jsip.2013.43B032
Abstract:

This paperstudiesthe effect of symmetry process on the compression parameters of thefractal image compression technique proposed by Jacquin.Two kinds of tests have been conducted. The first all kind of the symmetry operations [0-7] were taken; while the second tests were concentrated on studying the effect of the following parameters Block Size, Step Size, Domain Size on the probability distribution of symmetry operation. The results show that the higher value of PSNR and the lower value of ET occur atevensymmetry operation only, but compression ratio is not affected with symmetry process. Also the occurrence probability of even symmetry is more than odd symmetry for all compression parameters. This behaviour can be utilized to reducethe encoding time to 50% with preserving PSNR.

 

Fractional Order Generalized Thermoelastic Infinite Medium with Cylindrical Cavity Subjected to Harmonically Varying Heat  [PDF]
Hamdy M. Youssef, Eman A. Al-Lehaibi
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.31004
Abstract: In this work, a mathematical model of an elastic material with cylindrical cavity will be constructed. The governing equations will be taken into the context of the fractional order generalized thermoelasticity theory (Youssef 2010). Laplace transform and direct approach will be used to obtain the solution when the boundary of the cavity is exposed to harmonically heat with constant angular frequency of thermal vibration. The inverse of Laplace transforms will be computed numerically using a method based on Fourier expansion techniques. Some comparisons have been shown in figures to present the effect of the fractional order parameter and the angular frequency of thermal vibration on all the studied felids.

Eman A. N. Al-Lehaibi, Hamdy M. Youssef
World Journal of Nano Science and Engineering (WJNSE) , 2015, DOI: 10.4236/wjnse.2015.54020
Abstract: In this paper, we will study the most important effects in the nano-scale resonator: the coupling effect of temperature and strain rate, and the non-Fourier effect in heat conduction. A solution for the generalized thermoelastic vibration of nano-resonator induced by thermal loading has been developed. The Young’s modulus is taken as a linear function of the reference temperature. The effects of the thermal loading and the reference temperature in all the studied fields have been studied and represented in graphs with some comparisons. The Young’s modulus makes significant effects on all the studied fields where the values of the temperature, the vibration of the deflection, stress, displacement, strain, stress-strain energy increase when the Young’s modulus has taken to be variable.
