Dynamic culture systems

Examining the concepts and principles of patient safety as related to organizational dynamics, culture, system methods, and key patient safety initiatives, the book supplies essential knowledge of healthcare safety risks, challenges, and controls. It includes information on leadership, management, communication skills, and understanding accidents.

Figure 27. Human osteoblast-like MG 63 cells in cultures on porous (A) or fibrous (B) poly(L-lactide-co-glycolide) scaffolds. A A summarizing picture of horizontal optical sections. The depth of cell ingrowth into the pores (average pore diameter of 400-600 mm) is indicated by spectral colors (blue 0-60 mm, green 80-160 mm, yellow 180-220 mm, orange 240-300 mm, red 320-400 mm, violet 420-480 mm). Day 14 after seeding, cells stained with propidium iodide. B cells grown for 4 days in static culture followed by 2 days in dynamic perfusion cell culture system. Cell membrane stained with Texas Red C2-maleimide and the nuclei counterstained with Hoechst 33342. Leica TCS SP2 confocal microscope, objective 5x (A) or lOx (B) [37].

Previously, hver shces were incubated in static organ cultures [1]. Hart et cd. [49] cultured rat hver slices for 24 h spread out on wet filter paper, floating on top of the incubation medium. Several slice-containing vessels were placed in a box with saturated 95% O2 and 5% CO2 at 37°C. However, the shces employed were rather thick (approximately 0.3 mm) and only the upper cell layers (0.2 mm) in the slice contained viable ceUs. Together with the introduction of the Krumdieck sheer [5,46], a new incubation technique for shces, the dynamic organ culture system (DOC), was introduced [35]. The main characteristic of this system is the intermittent exposure of the shce to incubation medium and the gas phase. The DOC is in fact a modified version of the Trowell incubation system [1].

Strengthen basic studies of pathogen population dynamics as influenced by cultural systems and resistant cultivars. Determine criteria for epidemic development. 

The perfusion culture systems are classified into two types by static and dynamic methods as shown in Fig. 12. 

States of Consciousness, a classic by world authority Charles T. Tart, is a basic understanding of how the mind is a dynamic, culturally biased, semi-arbitrary construction and system. A systematic exploration of how and why altered states can come about and their possibilities. As a student of his remarked, For the first weeks of class I didn t understand what those diagrams were about, but Ive realized the book is all about the way my own mind works Useful in understanding some of the important ways your mind works before you start altering it. 

When several populations of microorganisms inhabit a common abiotic environment they will almost invariably interact with one another. Attempts to construct theories of the dynamics of such systems—that is, to construct theories which will predict how the systems evolve in time—must be based therefore on knowledge of what interactions occur and on the kinetics of such interactions. Hence, the rest of what I have to say will focus on what is known about interactions in simple mixed culture systems.
