In Bodega Harbor, California, the nemertean Paranemertes peregrina spawns in June or July. Adults in the study area were small in comparison to worms found on two Washington mud flats. Population density of active worms averaged 7.38 worms/m 2 , with much variation due to time of day of low tides. Approximately 28 percent of the active population ate during the low tide periods that were sample...

The antimicrobial activity of the oil extracted with n-hexane from the seeds of Moringa peregrina was tested against Staphylococcus aureus, S. epidermidis, Pseudomonas aeruginosa, Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, Candida albicans, C. tropicalis and C. glabrata. The oil proved effective against all of the tested microorganisms. Standard antibiotics (netilmycin, 5-fl...

The mode of action of a bactericidal protein (sarcotoxin I) purified from the haemolymph of Sarcophaga peregrina (flesh-fly) larvae was studied, focusing attention on its effect on the function of the membrane of Escherichia coli. Sarcotoxin I almost completely blocked the uptakes of tetraphenylphosphonium ion and proline, which are known to be driven by a membrane potential, indicating that th...

The hemolymph of Sarcophaga peregrina (flesh fly) larvae was found to contain multiple inhibitors of hemocyte cysteine protease. One of them, named sarcocystatin A, was purified and found to be a mixture of the components sarcocystatin A, and AP in a molar ratio of 2:l. These components can exist in either the associated or dissociated form. The apparent heterogeneity of the protease inhibitors...

El artículo propone una aproximación a Los trabajos de Persiles y Sigismunda para analizar dos personajes (Arnaldo la peregrina Talavera) desde perspectiva del concepto. La comprensión peregrino como concepto, no sólo personaje arquetípico, permite observar propuesta cervantina sobre un panorama posturas ante el camino.

More than 30% of Buccella peruviana (D'Orbigny), Globocassidulina crassa porrecta (Earland & Heron-Allen), Cibicides mackannai (Galloway & Wissler) and C. refulgens (Montfort) indicate the presence of cold Sub Antarctic Shelf Water in winter, from 33.5 to 38.3º S, deeper than 100 m, in the southern part of the study area. In summer, the abundance of this association decreases to less than 15% a...

The anatomy and ultrastructure of root nodules of Anadenanthera peregrina var. falcata (Leguminosae-Mimosoideae) were analysed, as was plant growth. To ensure that nodules developed, seedlings were inoculated with a mixture of six strains of rhizobia. Nodules were produced that differed in appearance-and probably also effectiveness-but their structure was similar and they showed characteristics...

Frente al gran relato de los estudios transpacíficos del Galeón Manila, a menudo extendido en espacios, procesos y volúmenes documentales corte económico, este artículo se enfoca la observación un fenómeno histórico local, pero completamente imbricado red interacciones producidas por primera globalización, saber: itinerancia tres individuos ordinarios procedentes mundo asiático, su establecimie...

Background and purpose: Phenol is one of prevalent contaminants found in many industrial wastewaters. The combination with special features, such as high toxicity, carcinogenic properties, vitality gathering ability, low biodegradation potentiality and others, based on the U.S Environmental Protection Agency, classified as a priority pollutant. The purpose of this study was to determine the eff...
