The constant renewal of membranes in these cells require the active biosynthesis of phospholipids and neutral lipids, and a high level of expression of both retina-specific and housekeeping genes, a dynamic transport system and a huge energy supply.
These results support the thesis that the red cell represents a large repository for Pb, maintaining plasma Pb concentration within closely defined limits, and that methods other than measurements of plasma Pb will be necessary to uncover a presumably dynamic transport system between red cell and plasma.
A nonlinear dynamic refrigerated transport system model, which consists of a refrigeration unit and a cargo space, is developed.
The endosomal pathway constitutes a highly dynamic intracellular transport system, which is composed of vesicular and tubular compartments.
At all times the host cell was able to distribute resources to all parts of itself, and at all times the energetic price of evolving a dynamic intracellular transport system was paid for in the hard currency of ATP, made available by the slow loss of unnecessary endosymbiont genes over many generations.
Eukaryotic cells contain a highly dynamic vesicle-mediated transport system which selects and delivers proteins and lipids to different subcellular organelles.
The reality is very much different, especially in the transport sector, due to the complex and dynamic nature of the transport system and the interplay between the many sub-systems that comprise it.
This indicates that myosin-Va and dynamic actin comprise a transport system and not a tether as suggested previously [ 9].
The human immune system requires a highly dynamic and efficient intracellular transport system for the timely and targeted delivery of key immune molecules, including cytokines, chemokines and lysosomal enzymes, to their respective target sites [ 10, 11].
Transcriptional profiling studies demonstrate that genes involved in mitochondrial energy metabolism are coordinately up-regulated in multiple tissues with calorie restriction (CR), suggesting a change in dynamic of the electron transport system and a role for this alteration in mitochondrial metabolism in the mechanisms of CR (Lee et al., 1999, 2002).
This paper utilizes MAS to separate complicated dynamic urban public transport systems, which includes a variety of factors such as man, vehicle, road, environment and so on, into small concerted system that are easy to manage.
