BACKGROUND Although ozone-depleting methyl bromide was destined for phase-out by 2005, it is still widely applied as a consequence of various critical-use-exemptions and mandatory international regulations aiming to restrict the spread of pests and alien species (e.g. in globalized transport and storage). The withdrawal of methyl bromide because of its environmental risk could fortuitously help...

PURPOSE Rocuronium bromide is a nondepolarizing neuromuscular blocking drug and has been used as an adjunct for relaxation or paralysis of the skeletal muscles, facilitation of endotracheal intubation, and improving surgical conditions during general anesthesia. However, intravenous injection of rocuronium bromide induces injection pain or withdrawal movement. The exact mechanism of rocuronium ...

Atom transfer radical addition of bromonitromethane and 1,2-dibromotetrafluoroethane to alkenes is described. The reaction performed under blue light irradiation using two catalysts: 4CzIPN manganese (II) bromide. cyanoarene photocatalyst serves for the redox activation starting organic bromide, while salt facilitates trapping alkyl with formation carbon–bromine bond.

When iodides are administered in ordinary doses excretion takes place rapidly. Heavy doses can usually be administered before toxic symptoms develop. The same is true to an even greater extent of bromides. The bromide ion appears to be capable of replacing the chloride ion to a Considerable degree in the body fluid of mammals without the production of distinct toxic symptoms. Thus Frey (1910--1...

The effects of internal tetrabutylammonium (TBA) and tetrapentylammonium (TPeA) were studied on human cardiac sodium channels (hH1) expressed in a mammalian tsA201 cell line. Outward currents were measured at positive voltages using a reversed Na gradient. TBA and TPeA cause a concentration-dependent increase in the apparent rate of macroscopic Na current inactivation in response to step depola...

Hexamethylene-1,6-bis-(N,N-dimethyl-N-dodecylammonium bromide), pentamethylene-1,5-bis(N,N-dimethyl-N-dodecylammonium bromide), tetramethylene-1,4-bis(N,N-dimethyl-N-dodecylammonium bromide), trimethylene-1,3-bis(N,N-dimethyl-N-dodecylammonium bromide) and ethylene-1,2-bis(N,N-dimethyl-N-dodecylammonium bromide) have been obtained and characterized by FTIR and NMR spectroscopy. DFT calculations...

The metabolism of halothane during and after anaesthesia was studied in eight patients of different age and body weight by estimating the concentration of halothane and one of its metabolites (bromide) in the blood. A gas chromatograph with an electron capture detector was used to estimate halothane, while blood bromide levels were measured by neutron activation analysis. There was an initial b...
