Kinetic study for removal of cationic hexamethyl pararosaniline chloride dye using phytoremediation.

The present investigation provides a kinetic study for the removal of hexamethyl pararosaniline chloride, a hazardous dye, by phytoremediation using a water plant. It reveals Salvinia molesta has a phytoremediation tendency. The ability of Salvinia molesta to remove crystal violet (CV) dye is investigated with kinetic study in this research.

Facile microwave-mediated transformations of 2-butene-1,4-diones and 2-butyne-1,4-diones to furan derivatives.

Several di- and triarylfuran derivatives were prepared in high yields from but-2-ene-1,4-diones/but-2-yne-1,4-diones using formic acid in the presence of a catalytic amount of palladium on carbon and in poly(ethylene glycol)-200 medium in a one-pot operation under microwave irradiation (1-5 min).

Does the addition of clonidine affect duration of analgesia of bupivacaine wound infiltration in inguinal hernia surgery?

We conducted a prospective, randomized, double-blind study to compare analgesia obtained by wound infiltration using 29 ml of 0.25% bupivacaine alone, or with the addition of clonidine hydrochloride 150 micrograms. A third group received bupivacaine wound infiltration with clonidine 150 micrograms i.

Extradural air as a cause of paraplegia following lumbar analgesia.

A 52-year-old woman with chronic back pain presented for lumbar extradural analgesia. The 'loss of resistance to air' technique was used to locate the extradural space. Prolonged paraesthesia and paresis of left leg occurred following the procedure.

Use of atracurium infusions for general surgical procedures including cardiac surgery with induced hypothermia.

Atracurium was administered by infusion to four patients undergoing general surgical procedures. A mean infusion rate of 0.0068 +/- 0.
