    NANOFIBRE ENCAPSULATION OF LIMONENE AND MODELLING ITS RELEASE MECHANISMS
    (Akademiai Kiado Zrt, 2019) Dede, S.; Altay, F. Lokumcu
    In this study, limonene was encapsulated by using gelatine, Na-alginate, polyvinyl alcohol, lactalbumin or xanthan gum with the uniaxial electrospinning process. The highest encapsulation efficiency was obtained for the sample containing polyvinyl alcohol. The release kinetic studies of nanofibre encapsulated limonene were carried out at 5.5, 20, and 38.5 degrees C. The Peppas equation expressed the release behavior of limonene for all systems very well, indicating quasi-Fickian diffusion. The modelling data suggested that maybe more than one mechanism was involved for the release at 20 degrees C. The activation energy for releasing limonene from the electrospun polyvinyl alcohol-alginate encapsulation system was found to be 6.2 Id mol(-1) from the Arrhenius equation.

    Serum biochemical profile and protein fractions in cattle with Theileriosis
    (Ecole Nationale Veterinaire Toulouse, 2014) Dede, S.; Altug, N.; Deger, Y.; Ozdal, N.; Ceylan, E.
    Theileriosis encountered frequently in Van region and causes huge economic losses in cattle, sheep and goats. This study was carried out to examine the serum biochemical profile and serum protein fractions, determined before and 7 days after buparvaquone treatment, in 28 cattle, diagnosed to be infected with T. annulata and in 15 healthy control animals from the same region. The ALT (alanine amino transferase) and ALP (alkaline phosphatase) activities and the concentrations of bilirubin and urea were markedly increased in sera from infected animals whereas the concentrations of glucose, minerals (Na, K and Ca), total proteins, albumin and of a-globulins and the albumin/globulin (A/G) ratios were significantly depressed compared to the controls. In addition, buparvaquone treatment succeeded in alleviating the serum biochemical anomalies. These results show that liver and kidney failures occur during theileriosis leading to a global protein deficiency and that serum biochemistry and serum protein analysis may allow biochemical evaluation of treatment.
