K+ channel function is regulated through the assembly of channel subunit isoforms into either homo- or heterotetrameric structures each characterized by distinct pharmacologic and kinetic properties. In studying the molecular basis of subunit association in mammalian Shaker-like K+ channels, we constructed deletion mutants of the inactivating K+ channel(More)
Mammalian voltage-gated K+ channels are oligomeric proteins, some of which may be composed in vivo of subunits derived from several similar genes. We have studied N-type inactivation in the rapidly inactivating Kv1.4 channel and, in specific, heteromultimers of this gene product with Kv1.5 noninactivating subunits. Heteromultimeric channels were analyzed(More)
absTracT A mammal survey was conducted at 2500 m on the eastern slope of Volcán Sumaco, Napo Province, Ecuador. Volcán Sumaco is located east of the eastern slope of the Andes. The mountain is isolated from the eastern cordillera of the Andes by the Río Cosanga and Río Quijos River Valleys. The ecosystem of the survey area is Temperate Mountain Forest(More)
abStraCt In 2010 a mammal survey was conducted in an ecotone region (including páramo and temperate forest) on the eastern slope of the Andes in Sangay National Park, Ecuador. Sherman traps, Tomahawk traps, pitfall traps, and mist nets were used to collect mammal specimens at two sites (3,400 m elevation and 2,962 m elevation). A total of 169 specimens(More)
abStRact In 2008 a mammal survey was conducted in humid tropical forest on the western slope of the Andes near the town of Santa Rosa. Sherman traps, tomahawk traps, pitfall traps, and mist nets were used to collect mammal specimens at two sites (450 m elevation and 702 m elevation). A total of 113 specimens of 32 species were collected from the survey(More)

aBStract In 2014, a mammal survey was conducted in an ecotone region (including páramo and temperate forest) on the Eastern Versant of the Andes in Carchi province, Ecuador. Sherman traps, Tomahawk traps, pitfall traps, and mist nets were used to collect mammal specimens at two sites (3,340 m elevation and 3,650 m elevation). A total of 142 specimens(More)
In this study, the genetic substructure and morphology of the species Neusticomys monticolus was evaluated. A nuclear marker and mitochondrial maker were used to examine phylogeographic structure and to estimate genetic distances. Two statistical measurement analyses were applied to morphological data. These data recovered two morphologically distinct(More)

Using small-angle x-ray diffraction from centrifugally oriented acetylcholine receptor (AChR) enriched membranes coupled with anomalous scattering from terbium ions (Tb3+) titrated into presumed Ca2+ binding sites, we have mapped the distribution of Tb3+ perpendicular to the membrane plane using a heavy atom refinement algorithm. We have compared the(More)

In optical communications, clock recovery, optical time demultiplexing, and 3R regeneration are known as optical signal processing. Ultra-fast optical signal processing techniques are mandatory in future high-speed network and transmission systems to allow effective use of the large optical fiber bandwidth and the light speed capabilities. One solution is(More)
