Investigation of neurons

... stimuli, detected by receptors in the growth cone, direct the growth of the axon towards its target skeletal muscle. Long range cues are usually diffusible signals while short range cues are usually contact –mediated. Once the axons of the motor neurons reach the tissues they will innervate, ...

A question on dialysis tubing...help appreciated.

... discrimination. The driving force for transport is strictly diffusional. Transport occurs in the direction from highest to lowest concentration of diffusible substance. No active transport is possible. What selectivity there is is based on molecular weight alone. Biological membranes are lipid ...

... mechanism. Sensitivity to wavelengths less than 320 nm can be enhanced by prolonged aqueous bathing, which extracts urocanic acid and other diffusible epidermal chromophores. Optical properties of the dermis are modelled using the Kubelka-Munk approach, and calculations of scattering and ...

... FliM, and FliN) and located at the base of the flagellar motor. The mechanism of function of the switch is unknown. Here we demonstrate that the diffusible clockwise-signal molecule, the CheY protein, binds to the switch, that the primary docking site is FliM, that the extent of CheY binding ...

The Fiber Disease

... expression of specific genes in a growth rate-II and cell density-dependent manner, a process known as quorum sensing. While the discovery of a diffusible Escherichia coli signaling pheromone, termed autoinducer 2 (AI-2), has been made along with several quorum sensing genes, the overall number ...
