the abilities of silybum marianum cell culture to biotransform benzaldehyde to benzyl alcohol in three culture systems were compared. callus cultures of silybum marianum were established from seedlings, and healthy suspensions and immobilized cultures grown on the murashige and skoog medium. s. marianum cells were immobilized in both agar beads and fiber cotton matrixes. benzaldehyde was fed to...

Stable transfected baby hamster kidney (BHK) cells expressing human a, 8, and y fibrinogen chains together, in various combinations of any two, or individually, were established. Several types of subunit interactions were observed in the intracellular extracts of the transfected BHK cell lines as well as in Hep G2 cells. These included: 1) formation of ay dimers linked by a disulfide bond(s), 2...

1. By using a monolayer of tissue culture cells, JTC-3, JTC-3’, JTC-3” and HeLa cells, the assays of neotetrazolium (NT) reduction at the cell level have been conducted on the cells without detaching the cells from the culture glass vessel wall. 2. It has been found that the activity of endogenous NT reductase is extremely high in the living tissue culture cells. The endogenous NT reductase act...

This paper analyzes the feasibility of quantifying design tradeoffs on the transient step response of a class of nonlinear systems. This feasibility analysis builds on available tools for the characterization of performance limitations in the optimal quadratic response of the class of strict feedback nonlinear systems. We present results that show that, as in linear systems, for certain classes...

Background: Present study aims to investigate if PMC of ovine oocytes in the presence of cilostamide a phosphodiesterase type 3 (PDE3) inhibitor can improve the shortcomings of conventional IVM system. Materials and Methods: Immature ovine oocytes were retrieved from pre antral follicles of abattoir ovaries by aspiration and after washing in Htcm + %10 FBS were immediately classified in four gr...
