There are 3 distinct types of glial cells in the optic lamina of the lobster: dark, light, and sheet cells, all distinguished from the neurons by being multipolar and not having dictyosomes. Dark cells are surrounded by intercellular material and together with light cells constitute a structural support for the groups of nerve cells. Light cells are also sheath cells for the neuron somata. The sheet cells have numerous flat processes which together form the 2 glial layers in which the synaptic region is sandwiched. An extensive system of extracellular cisterns between the sheet processes may serve for fluid transport towards the fibres and synapses, and the numerous vesicles in the sheet cells may represent an extension of the extracellular transport system.

To achieve success in endodontic treatment, the root canal system should be as sealed as possible with suitable material such as gutta-percha and sealer. Objective: This study compare the apical leakage of roots obturated with GuttaCore™, lateral condensation, and continuous wave obturation through a computerized fluid-transport system. Material and methods: Fifty-two freshlyextracted upper molars were used. The disto-buccal roots were cut and standardized to 10 mm long. The root canals were prepared at working length with WaveOne primary reciprocating files. The specimens were randomly divided and filled by one of the following obturation techniques: GuttaCore™, lateral condensation or continuous wave obturation, using SILCO sealer. The positive controls were left unfilled and the negative controls were totally coated with cyanoacrylate and three layers of nail polish. The roots were stored in relative humidity for 72 h at 37°C, allowing the sealer to set. After this period, the roots were connected to a computerized fluid-transport system, and the apical leakage was analyzed. Results: The results were expressed in µL.cmH2O-1.min-1 x10-4 1.36 atm. The data were statistically analyzed using one-way ANOVA and Tukey´s tests. The specimens of the positive control group showed extreme amounts of apical leakage. There was no leakage in the negative ontrols. The statistical analysis indicated that continuous wave obturation and GuttaCore™ showed lower leakage than the lateral condensation technique (p<0.05). No difference was found among the continuous wave obturation and GuttaCore™ (p>0.05). Conclusion: Continuous wave obturation and GuttaCore™ showed lower leakage than the lateral condensation technique. There was no difference between the continuous wave obturation and GuttaCore™. The fluid-transport system used in this study allowed an accurate quantitative measurement of leakage using simpler equipment.

Branching Hierarchy

Using the diameters of the channels at branch points, we quantitatively test three alternative models of the function of astrorhizae in stromatoporoids. The distribution of diameters at branch points is significantly different from the distribution that would be predicted from models of either a diffusive function or a bulk-flow system in which resistance to flow was constant at all levels of the branching hierarchy. The distribution of channel diameters is virtually identical to that predicted by a model (Murray's law) that simultaneously minimizes resistance to flow and some volume-related cost function. Astrorhizae thus carried a bulk flow of fluid and can be inferred to have been lined with cellular elements; the exchange sites associated with the fluid-transport system were distributed throughout the soft tissues of the stromatoporoid animal. The most parsimonious hypothesis of function, that the fluid-transport system was associated with suspension feeding, implies strong similarities between the structure of the stromatoporoid animal and living sponges.
