Bashtar, A. - R., M. Hassanein, F. Abdel-Ghaffar, K. Al-Rasheid, S. Hassan, H. Mehlhorn, M. AL-Mahdi, K. Morsy, and A. Al-Ghamdi, "Prevalence pattern and biology of Sarcocystis capracanis infection inthe Egyptian goats: A light and ultrastructural study", Veterinary Parasitology, 2011. Abstract

Cysts of Sarcocystis capracanis obtained from infected goats were examined to clarify the effect of the parasite on the host. Muscle tissues from fresh oesophagus, tongue, diaphragm and skeletal muscles of 680 goats were slaughtered in the main abattoir of Cairo, Egypt and they were examined microscopically for Sarcocystis infection for the first time in Egypt. 540 out of 680 (79.4%) of examined goats were found to be infected with Sarcocystis sp. The infection was recorded firstly by light microscopy as spindle shaped cysts embedded in the muscle tissues.

Saleh, H. A., A. M. M. A. El-Hariri, and M. K. Refai, "Prevalence of Yeasts in Human, Animals and Soil Sample at El-Fayoum Governorate in Egypt", International Journal of Microbioogical Reearch, 2011. Abstract

A survey was done for the most common yeast isolates from different clinical sources from human and animals in addition to environment samples from soil in El-Fayoum Governorate. The total of tested samples was 802 clinical and environmental samples. They consisted of fifty human vaginal swabs, seventy one human throat swabs, three hundred fifty seven animal vaginal swabs, one hundred seventy nine animal nasal swabs and one hundred forty five soil samples. The yeast isolates were representatives for only 3 species Candida albicans (110 isolates), Cryptococcous neoformans (20 isolates) and Rhodotorula rubra (66 isolates), on the basis of the conventional mycological identification tests. The results were confirmed by molecular identification for the representative isolates of Candida albicans and Cryptococcous neoformans recovered from different sources.

AbouLaila, M, El-Bahy, N, Hilali, M, Yokoyama, N., Igarashi, and I., "Prevalence of the Enteric Parasites of Ducks from Bebera Governorate, Egypt", J. Protozool, 2011. Abstract

This study of enteric parasites of ducks was undertaken to determine their prevalence and the relationships between their prevalence and the age and breed of ducks in the Behera governorate, Egypt. A total of 110 ducks of different ages and breeds were examined. The prevalence of helminths was 4.54% from which the prevalence of nematode, cestode, and trematode infections was 2.72%,3.63%, and 1.81%, respectively. The recovered nematodes were Ascaridia galli (0.9%) and Heterakis gallinarum (1.81%). The reported trematodes were Echinoparyphium recurvatum (0.9%) and Echinoparyphium paraulum (1.81 %). The new reported cestodes were Cladogynia phoeniconaiadis (3.63%), Echinolepis carioca (3.63%), and Baerfainia anoplocephaloides (3.63%). The helminths infections were only recorded in Native (5%) and White Peckin (11.11 %) and only in the 8-12-months age group. The prevalence of Entamoeba gallinarum was 0.9% and only recorded in one White Peckin of 8-12-months age group. Cryptosporidium species could not be detected in the examined ducks. This study presented the first record of three new cestodes in ducks from Egypt.

Kuchai, J. A., M. Z. Chishti, M. M. Zaki, J. Ahmad, M. Rasool, S. A. Dar, and H. Tak, "Prevalence of Nematode Parasites in Sheep of Ladakh -India", Journal of Agricultural Extension and Rural Development, 2011. Abstract

Nematode parasite infections of sheep are a major problem throughout the world and are responsible for economic losses in a variety of ways. In the present study an attempt was made to find out the various nematode parasites and their prevalence infesting the sheep of Ladakh region of Jammu and Kashmir State in India. A total of 313 sheep of either sex and of different age groups belonging to different areas of Ladakh were examined for nematode parasites, out of these 136 (43.45%) were found infected. The study reveals the presence of four species of nematodes viz; Trichuris ovis, Haemonchus contortus, Dictyocaulus filaria and Chabertia ovina. It was also observed that among these T. ovis was most dominant followed by H. contortus, D. filaria and C. ovina, respectively. Furthermore season, sex, age and agro-ecology show an association with prevalence.

El-Jakee, J., K. F. Mohamed, and S. A. Marouf, "Preparation of Autogenous Bivalent Vaccine for M", Life Science Journal, 2011. Abstract

In view of the decreasing effectiveness of antibiotics in controlling Mycoplasma infections and no vaccine is available against Mycoplasma in Egypt, the need for reliable vaccines has become even more urgent. The present study tried to prepare two bivalent autogenous vaccines (saponised and formalized vaccines) able to protect against M. bovis and M. bovigenitalium. The prepared vaccines were experimentally injected in groups of rabbits and challenged with virulent strain of M. bovis and M. bovigenitalium. Both saponised and formalized vaccines were able to protect rabbit against M. bovis and M. bovigenitalium. Meanwhile saponised vaccine was safe and more potent than formalized vaccine. Experimental work had shown that a vaccine inactivated with saponin can protect in the face of a large Mycoplasma challenge and was highly immunogenic.

Elsabee, M. Z., M. Nassar, and S. Elbegawy, "Preparation and Characterization of Some Aromatic/ Aliphatic Polyamides", American Journal of Polymer Science, 2011. Abstract

Aromatic diamine and phthaloyl chloride have been copolymerized using interfacial polymerization technique. Ethylene diamine (EDA) in 20, 30, and 40% and diamino butane (DAB) with the same molar ratio were used in addition to p-phenylene diamine to prepare polyamide with aliphatic components in the chain. The copolymers were characterized by FTIR Viscosity measurements were obtained in concentrated sulphuric acid.Thermogravimetric analysis and DrTGA showed that the thermal stability of the prepared polymers decreases by increasing of the ratio of the aliphatic diamines. The aliphatic content affects the crystallinity of the prepared polymers as was shown by X-ray diffraction measurements. Scanning electron microscopy revealed that the aliphatic components cause the copolymers to have a more homogeneous appearance with a different morphology.

Ismail, M., and W. M. Seif, "Prediction of Accidental Cancellation of Different Deformation Components and Optimum Fusion Orientations", Nuclear Physics A872: 25, 2011. Abstract

In view of the role of nuclear deformations in the fusion between spherical and deformed nuclei to form super-heavy elements, we try to understand how a cancellation of the different nuclear deformations could arise. We first investigated the correlation between the orientation variation of the deformed nucleus radius and the orientation Coulomb barrier distribution in presence of the higher order deformation components, b6 and b8, in addition to the lower order ones. This correlation has been reported in our previous work (Ismail and Seif, 2010) [1] in presence of the lower order (b2, b3 and b4)) deformations. Even if there are higher deformations, we found here that the simple expression which describes the deformed target nucleus can be used to predict with good accuracy the behavior of the fusion Coulomb barrier with both orientation and deformation as well as the optimum (cold or hot) fusion configurations. It can predict the orientations of compact and elongated configurations of the interaction and whether they are equatorial or polar or none of them. The value and sign of the deformation parameters ratios with respect to one of them have been used to classify these configurations. We applied the same correlation to predict successfully the mutual cancellation effects between the different deformation components up to to b8.. Illustrative examples are given in which the cancellation, at some orientations, brings the fusion barrier back to the spherical case or keeps only the effect of quadrupole deformation, or the effects of both b2 and b4.

Mohamed, M. M. A., and M. M. Shoukry, "Potentiometric Studies of the Interaction of Amine-bridged Dinuclear Palladium(II) Complex with Nitrogen Bases", Journal of Coord. Chemistry, 2011. Abstract

Complexes formed by interaction of trans-diamminepalladium(II) chloride (PdII) with1,6-hexanediamine (HDA) and nitrogen bases (B) (imidazole derivatives or methylamine) areinvestigated at 25_C and 0.1 mol L_1 NaNO3 ionic strength using potentiometric measurements.The stability constants of all possible mononuclear and binuclear complexes weredetermined. The concentration distribution diagram of the binuclear PdII-HDA-Im derivativereveals the complexes predominating in the physiological pH range; the reaction ofthe binuclear PdII-HDA-PdII with imidazole derivatives is quite feasible.

Maghraby, A. E. M., A. E. M. Kammar, and M. S. Mabrouk, "Potentiality of Clays in the Kharga-Dakhla Land Stretch as A Natural Landfill Liner in A Hyperarid Region", Environmental Geosciences, 2011. Abstract

Engineered landfill liner systems are expensive to install and represent a challenge to several developing countries. Alternatively, native soils, preferentially clays, can be used as cost-effective bottom liners.The purpose of this work is to justify the reliance on the ability of the clays at the Kharga-Dakhla land stretch, Western Desert, Egypt, to act as a containment and barrier for pollutants that might be generated in a landfill leachate.

Khedr, A., V. Papadakis, P. Pouli, D. Anglos, and M. A. Harith, "The Potential use of Plume Imaging for Real-Time Monitoring of Laser Ablation Cleaning of Stonework", Applied Physics, vol. 105, issue 2, pp. 485, 2011. AbstractCU-PDF.pdf

In this work, the potential of plume imaging was investigated as a real-time monitoring technique for the control of the laser cleaning process in cultural heritage objects with emphasis on encrusted stonework. Optical pulses generated by Nd:YAG laser were used to remove a high absorbing layer of crust from the surface of a lower absorbing marble substrate. Two regimes of operation have been employed for laser cleaning test, Q-switched ns mode, and short free running ?s mode. Laser induced breakdown spectroscopy (LIBS) was also employed to study the stratigraphy of the cleaned surfaces, and thus to confirm the validity of the suggested monitoring technique.

Graham, P. J., C. M. Neely, and E. A. A. Maghraby, "Polymer relaxation, 1 st ed", Nova Science Publishers, 2011. Abstract

Badawy, W. A., K. M. Ismail, and S. S. Medany, "Polyaminoanthraquinone Modified Electrodes as Electroanalytical Sensors", Int. J. Electrochem. Sci., 2011. Abstract

Poly 1-amino-9,10-anthraquinone, PAAQ, films were prepared by the electropolymerization of 1-amino-9,10-anthraquinone, AAQ, on platinum substrates. The polymerization process was carried out in both nonaqueous (Acetonitrile containing 0.1 mole L-1 LiClO4 as supporting electrolyte) or aqueous (6.0 mol L-1 H2SO4) media. The electropolymerization process is fast and economic. The prepared films are stable and have been used as sensors for the electroanalytical determination of p-aminophenol, ascorbic acid, dopamine, hydroquinone, catechol, pyrogallol, cerium chloride and epinephrine. The determination is based on the cyclovoltammogramic method. The cyclic voltammetry was always carried out under the same conditions, where a scan rate of 100 mV s-1 in the specified potential range for each electrolyte at room temperature were used. A range of concentration between 0.01 to 1.0x10-4 mol L-1 analyte was perfectly determined. The determination process is based on the oxidation peak currents of the analyte in the cyclic voltammogram obtained by the PAAQ modified electrode. A calibration curve was drawn for each analyte from which any unknown concentration in the specified range of measurements could be accurately obtained from the value of the peak current.

Atta, N. F., A. Galal, and R. A. Ahmed, "Poly(3,4-ethylene-dioxythiophene) Electrode for the Selective Determination of Dopamine in Presence of Sodium Dodecyl Sulfate", Bioelectrochemistry, 2011. Abstract

A novel biosensor using poly(3,4-ethylene dioxythiophene) (PEDOT) modified Pt electrode was developed for selective determination of dopamine (DA) in presence of high concentrations of ascorbic acid (AA) and uric acid (UA) with a maximum molar ratio of 1/1000, and 1/100 in the presence of sodium dodecyl sulfate (SDS). SDS forms a monolayer on PEDOT surface with a high density of negatively charged end directed outside the electrode. The electrochemical response of dopamine was improved by SDS due to the enhanced accumulation of protonated dopamine via electrostatic interactions. The common overlapped oxidation peaks of AA, UA and DA can be resolved by using SDS as the DA current

Hegazy, A. K., N. T. Abdel-Ghani, and G. A. El-Chaghaby, "Phytoremediation of Industrial Wastewater Potentiality by Typha Domingensis", International Journal of Environmental Science and Technology, 2011. Abstract

Phytoremediation is increasingly receiving attention as a cost effective technique that uses plants to remediate contaminants from wastewater, soil and sediments. In this study, the ability of Typha domingensis to uptake heavy metals as well as its potential application for phytoremediation was assessed. Pollutant elements concentrations were measured in samples of wastewater, sediments and Typha domingensis collected from industrial wastewater ponds, El-Sadat city, Egypt. This study specifically focused on the capacity of Typha domingensis to absorb and accumulate aluminum, iron, zinc and lead. Results indicated thatTypha domingensis was capable of accumulating the heavy metal ions preferentially from wastewater than from sediments. The accumulation of metals in plant organs attained the highest values in roots, rhizomes and old leaves. Rhizofiltration was found to be the best mechanism to explain Typha domingensis phytoremediation capability.

Elfeky, S. A., and A. - S. A. Al-Sherbini, "Photo-Oxidation of Rhodamine-6-G via TiO2 and Au/TiO2-Bound Polythene Beads", Journal of Nanomaterials, 2011. Abstract

It is very important to improve the efficiency of water detoxification techniques. In this study, TiO2 or gold-TiO2 (Au/TiO2) nanocomposite-bound polythene beads were used for the photo-oxidation of rhodamine 6G (R6G) as a model of water organic pollutants. Simple thermal procedures were employed for anchoring TiO2 or Au/TiO2 nanocomposites to polythene beads. The results revealed that the synthesized Au/TiO2 composites exhibited both considerably higher absorption capability of organic pollutants and better photocatalytic activity for the photo-oxidation of R-6G than pure titania. The better photocatalytic activity of the synthesized Au/TiO2 composites film than that of the pure titania film was attributed to high capacity of light absorption intensity and easy diffusion of absorbed pollutants on the absorption sites to photogenerated oxidizing radicals on the photoactive sites.

Ramadan, A., and A. A. M. El-Aty, "Pharmacokinetics and Distribution of Florfenicol in Bronchial Secretions of Healthy and Pasteurellamultocida Infected Calves", Pharmaceutica Analytica Acta, 2011. Abstract

Florfenicol was administered intravenously and intramuscularly at a dose rate of 20 g/kg bwt to determine itsconcentration in blood and bronchial secretions as well as kineticbehavior in healthy and diseased calves. Severacute bronchopneumonia was induced via inoculating the animals with Pasteurellamultocida. Following intravenous(i.v) administration, the serum concentration - time curve indicated a two compartment open model with a meanelimination half-lives (t1/2?) of 4.10 and 4.84 h in healthy and infected calves, respectively. The mean volumes ofdistribution at steady state (Vdss) were 0.68 and 0.63 L/kg and the total body clearances (Cltot) were 0.15 and0.11 L/kg/h with mean residence time (MRT) of 0.05 and 0.05 h, respectively. Florfenicol was slowly eliminatedfrom serum and bronchial secretions with elimination half-lives (t1/2el) of (12.43 and 17.23 h) and (13.74 and 22.46h), respectively, following intramuscular (i.m.) injection. The peak concentrations (Cmax) in serum and bronchialsecretions were (3.70 and 4.06 ?g/ml) and (6.88 and 7.62 ?g/ml) attained at (3.07 and 3.01 h) and (1.54 and 1.70h), respectively. The drug is extensively distributed to bronchial secretions with AUCbronchial secretion / AUCserum ratio of 1:2.53 and 1: 2.03, respectively. The clinical and hematological parameters in calves treated intramuscularly returnedto normal faster than those treated intravenously. These results suggest that i.m. injection of florfenicol could be usedfor treatment of acute P. multocidabronchopneumonia in calves.
