Louis, USA) using the nonselective TRP channel blocker ruthenium red and the voltage--dependent [K.sup.+] channel blocker XE 991 in the hot plate, tail immersion, and writhing tests.
Louis, USA) using the nonselective TRP channel antagonist ruthenium red (3 mg/kg) and the voltage-dependent [K.sup.+] channel (Kv7; KCNQ) blocker XE 991 (1 mg/kg).
Shortly before sunset (1932 EST) one fragment of each individual was placed into a beaker containing seawater plus one of four options--control: seawater; iono-mycin: seawater plus 4 [micro]mol [l.sup.-1] ionomycin; ruthenium red: seawater plus 1 mmol [l.sup.-1] ruthenium red; thapsigargin: seawater plus 2 [micro]mol thapsigargin.
These were control, ionomycin, ruthenium red and thapsigargin.
The strong trendy colours include black and red, violet and white, cyclamen and pink, black and light blue plus dark ruthenium red
Histochemical tests with Ruthenium red showed pectic compounds in the cytosol.
The following histochemical tests were performed: Sudan IV for lipids; 10% aqueous ferric chloride to locate phenolic compounds; and Ruthenium red solution to detect pectic compounds (Johansen 1940).
Most biofilm volume is actually composed of this extracellular polymeric substance rather than cells, a fact that has been confirmed by ruthenium red
staining and transmission electron microscopy (2).
We next examined the effects on sea urchin sperm of ruthenium red, a potent inhibitor of ryanodine-sensitive channel activity (6-8).
Motility and calcium mobilization induced by SIN-1 in Arbacia punctulata sperm were also found to be inhibited by ruthenium red (Fig.
The attached podia were fixed according to the same protocol as the unattached podia but with the addition of 0.05% ruthenium red
to both the primary fixative and the postfixative (Luft, 1971).
