Marine Plants May Polarize Remote Fucus Eggs via Luminescence.
Fucus zygotes can be polarized by many environmental vectors. These include those created by pieces of all the intertidal marine plants tested. At distances of up to 5-10 mm away from such pieces, Fucus zygotes form their intitial outgrowths or germinate towards them. Earlier papers had inferred that this so-called 'thallus effect' is mediated by diffusing molecules. The present reinvestigation...
متن کاملUroplakins Do Not Restrict CO2 Transport through Urothelium*
Lipid bilayers and biological membranes are freely permeable to CO(2), and yet partial CO(2) pressure in the urine is 3-4-fold higher than in blood. We hypothesized that the responsible permeability barrier to CO(2) resides in the umbrella cell apical membrane of the bladder with its dense array of uroplakin complexes. We found that disrupting the uroplakin layer of the urothelium resulted in w...
متن کاملDo sweetening agents interact with morphine-induced analgesia in the formalin test in mice?
There is evidence that sweeteners such as sucrose and saccharin interact with endogenous opioid systems. Further research has shown that feeding different concentrations of sucrose and saccharin alter latency in the tail-flick test. In this study, the influence of a 12-day regimen of different sweetening agents, sucrose (32%), saccharin (0.08%) and aspartame (0.16%) on morphine-induced analge...
متن کاملThe Air Turbine Ultracentrifuge, together with some Results upon Ultracentrifuging the Eggs of Fucus serratus
GENERALLY, the force of gravity has little or no effect upon the distribution of the various materials within cells, although they may differ considerably in their relative specific gravity. However, by means of the centrifuge forces can be obtained many times greater than gravity, which otherwise exist only on the very largest planets. Because of this fact, the centrifuge has proved to be a ve...
