(Sub-)millimetre observations of the polarized emission of aligned aspherical dust grains enable us to study the magnetic fields within protoplanetary disc. However, the interpretation of these observations is complex. One ...

Unraveling bacterial strategies for spatial exploration is crucial for understanding the complexity in the organization of life. Bacterial motility determines the spatiotemporal structure of microbial and controls infection ...

Featured Application The use of noble gas isotopic signature of fluid inclusions is increasingly being applied as a complement to traditional volcanic gas sampling and monitoring techniques. The chemical signature of fluid ...

The curricular renewal of Medical studies is a priority of the Faculty of Medicine of the University of Chile. After an initial phase of analysis done in 1994, the process must be accomplished through the elaboration of ...

The 1,5-benzodiazepine ring system exhibits a puckered boatlike conformation for all four title compounds [4-(2-hydroxyphenyl)2- phenyl-2,3-dihydro-1H-1,5-benzodiazepine, C21H18N2O, (I), 2-(2,3-dimethoxyphenyl)-4-(2-hydr ...

1 We recently described that several 2-(2,5-dimethoxy-4-substituted phenyl)ethylamines (PEAs), including 4-I = 2C-I, 4-Br = 2C-B, and 4-CH 3 = 2C-D analogs, are partial agonists at 5-HT 2C receptors, and show low or even ...

A new centrally active halo-amine, 4-bromo-2,5-dimethoxyphenylisopropylamine, is described. In clinical evaluation it proved to enhance effectively both emotional and intellectual perception, without the imagery and ...

4-Dimethylaminophenethylamine (DMAPEA) was characterized as an MAO substrate. This compound was unaffected by MAO-A, while its oxidation by MAO-B was linear as a function of both time and enzyme concentration, with Km = ...

4-Methylthioamphetamine (MTA) is a phenylisopropylamine derivative whose use has been associated with severe intoxications. MTA is usually regarded as a selective serotonin-releasing agent. Nevertheless, previous data have ...

Justificadamente, la economía chilena goza de fama de elevado crecimiento y de haber avanzado hacia el nivel de ingresos de las naciones más avanzadas. En efecto, en 1970 el PIB per cápita de Chile alcanzaba, por ejemplo, ...
