Edmardash, Y. A. - E., M. S. Abdel-Dayem, and N. S. Gadallah, "The subfamily Cheloninae (Hymenoptera, Braconidae) from Egypt, with the description of two new species", ZooKeys, 2011. Abstract

A key to the chelonine species (Braconidae) (both recorded and recently collected) from Egypt is given. It includes 16 species, of which five species are new to the Egyptian fauna and two (Phanerotoma (Phanerotoma) elbaiensis sp. n. and Phanerotoma (Bracotritoma) ponti sp. n.) are new for science. A faunistic list and the description for the two new species are added.

Abdel-Motelib, A., Z. A. Kader, Y. A. Ragab, and M. Mosalamy, "Suitability of a Miocene bentonite from North Western Desert of Egypt for pharmaceutical use", Applied Clay Science, 2011. Abstract

This work examines the beneficial effects for human health of bentonite, describing their use in pharmaceutical formulations. The bentonite samples must comply with some general features of pharmacopeia, including high mineral and chemical purities and absence of microbial pathogens, before considering their use in pharmacy. Specific characteristics such as sediment volume, swelling power and gel formation are also important for particular applications such as their use as suspending agents. Mineralogical, geochemical, and microbiological analyses and pharmacopeia tests were carried out for a purified (raw and activated) Egyptian bentonite sample from North Western Desert (NWD), a Wyoming bentonite standard and a mineral currently used as a pharmaceutical product. The X-ray diffraction data revealed that the Egyptian sample has montmorillonite as a main mineral phase.

Othman, S. H., M. S. El-Deab, and T. Ohsaka, "Superior electrocatalytic Activity of Au(110)-Like Gold Nanoparticles Towards The Oxygen Evolution Reaction", Int. J. Electrochemical Science, 2011. Abstract

This study is concerned with the electocatalytic evolution of oxygen gas at novel gold nanoparticles (nano-Au) modified glassy carbon (GC) electrodes in 0.5 M KOH. The electrochemical measurements show a superior enhancement of the nano-Au/GC towards the oxygen evolution reaction (OER) compared to bulk GC and Au electrodes. That is, the onset potential of the OER is shifted by ca. 600 mV in the negative direction compared with bulk Au and unmodified GC electrodes. The enrichment in the Au (110) facet orientation (of the electrodeposited nano-Au) [1] at the expense of other low facets orientations induces a favorable geometric arrangements of the Au surface atoms which is believed to facilitate the OH- adsorption and, hence, the charge transfer process during the water electrolysis into molecular oxygen. Thus, the OER is accelerated and realized at less positive potential.

El-Husseiny, I. N., A. M. A., A. A. Mostafa, and M. H. Elshakankery, "Surgical Management of Patellar Ligament Rupture in Dogs using A Prosthetic Woven Fabric: Experimental Study", The Journal of American Science, 2011. Abstract

A new synthetic fabric composed of a mixture of two biomaterials, polyamide 6.6 and polyester, was manufactured with specific tensile characters to serve in the reconstruction of the patellar ligament rupture in dogs. Twelve skeletally mature mongrel dogs with no evidence of clinical signs of lameness were used in the present study. Patellar ligament rupture was induced by severing the mid portion of the right ligament of each limb. Surgical intervention was performed by primary suturing of the severed patellar ligament ends and applying a synthetic fabric to act as a supportive internal splint. Satisfactory results were obtained concerning the tendon healing and the return to limb normal function without complications. It was found that the polyamide polyester fabric proved to be a suitable reconstructive biocompatible material that allowed primary ligament repair with adequate support by and giver an excellent outcome in cases of patellar ligament ruptures in dogs.

Synthesis of 4-phenylamino-5-phenyl-4H-[1,2,4]triazole-3-thiol (1) and 3-methylthio-4-phenylamino-5-phenyl-4H-[1,2,4]triazole (2) is described. Reactions of hydrazonoyl halides (3) with either 1 or 2 afforded 1,2,4-triazol[4,3-b][1,2,4,5]tetrazine. The latter products were screened for their antifungal and antibacterial properties. The structure of the products was established based on elemental and spectral analyses. Further evidence for the assigned structure of the products is based on alternative synthesis. The mechanism of the studied reactions was also discussed.

Thieno[2,3-b]pyridines 7, 8, 9 were obtained via the S-alkylation of 3 with a variety of alkylating agents followed by cyclization in basic medium. On the other hand, compound 3 reacted with methyl iodide to give compound 10 which is converted to pyrazolo[3,4-b]pyridine derivative 13 by reaction with hydrazine hydrate. Pyrido[3`,2`:4,5]-thieno[3,2-d]pyrimidines derivatives 14, 16 were obtained by reaction of 7 with each of formic acid and formic/formamide, respectively. Alternatively, compound 14 was obtained by the reaction of 8 with formamide. Structures of the newly synthesized products were determined by elemental analysis and spectral data.

The synthesis of antimicrobial activity spirocompounds was achieved via the reaction of hydrazonoyl halides 1 with exocyclic 4-arylidene-2-methylimidazolin-5-one 3 in benzene in the presence of triethylamine. Correct elemental analyses and spectral data (IR, 1H NMR, 13C NMR and MS) confirm the structure of the synthesized spirocompounds. All the synthesized compounds were evaluated in vitro for their antimicrobial activity against five gram-positive and two gram-negative bacteria using well diffusion method in Mueller-Hinton agar. Most of them exhibited significant antibacterial activity compared with selected standard drugs.

The stoichiometry and stability constants of the formed complexes are also reported, and the concentration distribution of the various complex species was evaluated as a function of pH. The results show ring opening of CBDCA and monodentate
