BIII 277 CL ((-)-2R-[2 alpha, 3(R*),6 alpha]-3-(2-methoxypropyl)-6,11, 11-trimethyl-2,6-methano-1,2,3,4,5,6-hexahydro-3-benzazocin-9-ol hydrochloride) is a novel benzomorphan with neuroprotective and anticonvulsant properties that exhibits high affinity binding to the N-methyl-D-aspartate (NMDA) receptor but, in contrast to other structurally related benzomorphans, low affinity for mu opiate an...

Air quality in greater Algiers, in Algeria was assessed analyzing aerosol particulate matter (PM10 and PM2.5) at a site influenced by heavy road traffic. Particulate matters were collected using a Gent sampler to characterize the atmospheric aerosol of Algiers. An Energy dispersive X ray spectrometer (EDXRF) was used to determine the heavy metal concentrations in the PM2.5 and PM10 size fractio...

A Gram-negative, aerobic, heterotrophic, non-pigmented, dimorphic prosthecate bacterium was isolated from tundra wetland soil and designated strain Z-0023(T). Cells of this strain had a dimorphic life cycle and developed a non-adhesive stalk at a site not coincident with the centre of the cell pole, a characteristic typical of representatives of the genus Asticcacaulis. A highly distinctive fea...
