AbstractNanoindentation and dynamic mechanical analysis were used to measure changes in the surface and bulk mechanical properties of Winsor & Newton Yellow Ochre oil paint films following exposure to deionized water, aliphatic mineral spirits (Shellsol D40™), and D5 silicone solvent (decamethylcyclopentasiloxane). Yellow ochre paint films were exposed to the selected solvents by 24-h immersion, and sponge-cleaning. 24-h immersion in deionised water and Shellsol D40 caused measurable changes to bulk and surface mechanical properties. However, there were no measurable changes to the bulk or surface mechanical properties following sponge cleaning.

The furosemide-sensitive uptake of thallium represents approximately equal to 50% of the total uptake of thallium by rabbit uterus and requires Cl- and Na+. The furosemide-sensitive uptake of thallium is stimulated by other ions at low concentrations with the rank order Li+ greater than Tl+ greater than K+ = Rb+ greater than Cs+ and is inhibited by these ions at high concentrations with the rank order Tl+ greater than K+ = Rb+ greater than Cs+ greater than Li+, suggesting multiple cation binding sites on the carrier. Uptake of 36Cl- is inhibited by furosemide in the presence of ouabain. Thallium efflux and 36Cl efflux in the presence of ouabain is inhibited by furosemide. The chloride concentration regulates the proportion of thallium uptake that is ouabain sensitive and furosemide sensitive without altering the total uptake. It is suggested that the furosemide-sensitive uptake of thallium reflects a Na+-Cl- -K+ exchange system that could be classified as a cotransport or countertransport of any two of these ions and also could be the smooth muscle chloride pump.

Background: Functional and pathological improvements following rapid rewarming in 42°C water was compared with alterations following slow thawing at room temperature (22°C) after frostbite (–9°C, 15 minutes) in vivo of the rabbit central ear artery. Methods: Following two to ten weeks of in vivo regeneration, vascular segments were tested in vitro. Maximal and dose-dependent isometric contractions were induced by exogenous noradrenaline. Sympathetic nerves in the vascular wall were stained with glyoxylic acid. Vascular ring segments were stained with haematoxylin and eosin. Results: Following slow thawing, the total uptake, the K+ evoked and the spontaneous release of [3H]noradrenaline in the sympathetic nervous system were strongly reduced two weeks after freezing, with a subsequent increase to control level within 3–4 weeks. After rapid rewarming the total uptake, the spontaneous release and the K+ evoked release of [3H]noradrenaline commenced earlier such that after ten weeks the level was twice as high as following slow rewarming. The glyoxylic acid induced catecholamine fluorescence in sympathetic nerves, revealed an earlier regeneration after rapid rewarming. Haematoxylin and eosin-stained segments revealed less intimal hyperplasia three to 20 weeks after rapid rewarming than after slow thawing. Conclusion: Rapid rewarming of in vivo frozen arteries in warm water (42°C) did not prevent immediate vasoparalysis and degeneration of sympathetic nerves. However, nerve regeneration occurred earlier and with higher tissue nerve densities as compared to tissue that had been slowly rewarmed. Myointimal hyperplasia was less pronounced after rapid rewarming. Abnormal sympathetic nerve function and myointimal hyperplasia, as observed in this study, may contribute to a greater understanding of sequelae in the human body following frostbite.
