Motility of the small intestine is a result of complex neurochemical and hormonal interactions within the intestine. The net motility (contraction) of the intestine is a balance of the influences from the central nervous system, enteric nervous system and hormonal changes in the body. Recently, the discovery of several peptide neurotransmitters common to the brain and the intestine has stimulated new research into the influence of these novel neurotransmitter candidates on intestinal motility at the level of the enteric (intestinal) nervous system.

Many bacteria use motility described as swarming to colonize surfaces and form biofilm. Swarming motility has been shown important to biofilm formation [1], where cells act not as individuals but as coordinated groups to move across surfaces, often within a thin-liquid film [2]. Production of a surfactant during swarm improves bacterial motility by lowering surface tension of the liquid film [2]. The mechanism of cell motion during swarming are currently best described for Escherichia coli and Paenibacillus spp., which spread as monolayers of motile cells [3,4]. For Pseudomonas aeruginosa (P.

Although desiccation preservation offers promise as an alternative method for the preservation of mammalian cells, there has been limited success in achieving survival at very low water content [1].

This factor coupled with the limited permeability of cell membranes leads to irreversible cellular damage. In the current study, we have studied the effect of hypertonic osmolality and exposure

To describe cell motility, we use a continuous stochastic process and estimate its parameters and driving force based on a maximum likelihood approach. In order to improve the convergence of the maximization procedure, we use expectation-maximization (EM) iterations. The iterations include numerical maximization and the Kalman filter. To illustrate the method, we use cell tracks obtained from the intravital video microscopy of a zebrafish embryo.
