Objective: The objective of this study was to prepare a controlled release system, which could be used in medical applications in order to treat infections at the host region. Methods: Microlayer films were prepared via solvent casting method. Films with 3-layers were prepared by using chitosan (CHI), gelatin (GEL) and alginate (ALG) in the form of CHI /ALG/CHI and CHI-GEL /ALG/CHI-GEL with or without ceftriaxone sodium (CS) which is loaded in the middle ALG layer. All films were crosslinked by exposing them to glutaraldehyde (GA) vapor for different (2 h, 10 h or 24 h) durations. Mechanical properties of the films and release kinetics of CS at three different pH conditions (pH 5.5, 7.4, and 10.0) were investigated. The antibacterial efficiency of the released CS against Escherichia coli was examined via agar spot test. Results: The results indicated that the presence of GEL in the upper and lower layers of the 3-layer construct prevented fragility and increased the mechanical strength of the films, whereas the presence of CS in the middle layer caused decrease in the mechanical properties. Crosslinking with GA did not demonstrate a significant effect on the release profile of CS, but due the interaction of chitosan with alginate and CS, the drug release was delayed. Antibacterial tests which were carried out by using the released media of drug loaded films displayed inhibition zone in agar spot tests against E. coli. Conclusion: It was concluded that multilayered films prepared by solvent casting can be good candidates as drug carrier devices in medical applications.

Capillary electrophoresis with online stacking in combination with AgNPs@MCM-41 reinforced hollow fiber solid-liquid phase microextraction for quantitative analysis of Capecitabine and its main metabolite 5-Fluorouracil in plasma samples isolated from cancer patients Forough, Mehrdad; Farhadi, Khalil; Molaei, Rahim; Khalili, Hedayat; Shakeri, Ramin; Zamani, Asghar; Matin, Amir Abbas (2017-01-01) The purpose of this study is the development and validation of a simple, novel, selective and fast off-line microextraction technique combining capillary electrophoresis with in-column field-amplified sample injection (FASI) for the simultaneous determination of capecitabine (CAP) and its active metabolite, 5-Fluorouracil (5-FU), in human plasma. At the moment, there is a lack of using cost-effective CE tool combined with novel miniaturized sample clean-up techniques for analysis of these important anticanc...
Immunoproteomic analysis of Bordetella pertussis and identification of new immunogenic proteins Altindis, Emrah; Tefon, Burcu E.; Yildirim, Volkan; Ozcengiz, Erkan; Becher, Doete; Hecker, Michael; Özcengiz, Gülay (Elsevier BV, 2009-01-22) Bordetella pertussis is the causative agent of highly communicable respiratory infection whooping cough (pertussis) which remains one of the world's leading causes of vaccine-preventable deaths. In the present study, total soluble proteins extracted from two B. pertussis strains, Tohama I and the local isolate Saadet were separated by two-dimensional gel electrophoresis and analyzed by Western blotting for their reactivity with the antisera obtained from the mice immunized with inactivated whole cells as we...
Fatty acid methyl ester analysis of bacterşal isolates from salt lake, Turkey and characterization of their extracellular enzymes Bahçeci, Hümeyra; Gültekin, Güzin Candan; Department of Biotechnology (2004) In this study, 11 bacterial isolates from Salt Lake,Turkey were identified by using fatty acid methyl ester (FAME) analysis. They were screened for production of industrially important enzymes xylanase, cellulase, a-amylase and protease. These enzymes were characterized in terms of enzyme activity, stability, optimum temperature and optimum pH. One of the isolates was identified as Bacillus pumilus, and two of them were identified as Bacillus subtilis. Other isolates were determined to be Bacillus lichenifo...
Multidrug-resistant Salmonella typhimurium, Pacific Northwest, United States Davis, Margaret A.; Besser, Thomas E.; Eckmann, Kaye; MacDonald, J. Kathryn; Green, Donna; Hancock, Dale D.; Baker, Katherine N. K.; Warnick, Lorin D.; Soyer, Yeşim; Wiedmann, Martin; Call, Douglas R. (Centers for Disease Control and Prevention (CDC), 2007-10-01) We compared human and bovine isolates of Salmonella enterica using antimicrobial-drug resistance profiles and pulsed-field gel electrophoresis. From 2000 through 2006, we observed an increase in a novel multidrug-resistant clone of S. Typhimurium with no recognized phage type. This clone may represent an emerging epidemic strain in the Pacific Northwest.
Novel bioconversion reactions for the syntheses of a-hydroxy ketones Ayhan, Peruze; Demir, Ayhan Sıtkı; Department of Biotechnology (2009) The objective of the study presented here was to develop either enzymatic or whole cell mediated green procedures for the syntheses of a-hydroxy ketones. Production of optically active synthons is crucial for the preparation of fine chemicals. Enzymes and whole-cell biocatalysts have proven to be excellent vehicles with their chiral nature for the biotransformations. Under the light of this discussion, firstly benzaldehyde lyase [BAL, (EC 4.1.2.38)] was used in novel C-C bond formation reactions to obtain i...
