Identificación de genes y proteínas relacionados con la producción de nanopartículas de selenio en Pseudomonas putida KT2440
(2019)Existen múltiples bacterias que pueden metabolizar selenito a selenio, no obstante, en muchos casos no se conocen bien los mecanismos mediante los cuales estos microorganismos llevan a cabo este proceso, siendo Pseudomonas ... -
Identification of circadian gene variants in bipolar disorder in Latino populations
(2015)Background: Variations in circadian genes can impact biological rhythms. Given the rhythm disturbances that characterize bipolar disorder (BD), genes encoding components of molecular clocks are good candidate genes for ... -

Illustrations and Studies in Neotropical Orchidaceae. 3. On the identity of Dracontia pachyglossa and D. ramonensis; with a new species, D. lueriana (Pleurothallidinae)
(2012)The Costa Rican Dracontia ramonensis is discussed and illustrated. It had been already illustrated as early as 1867 by A.R. Endres, but only described in 1923 by Rudolf Schlechter. Costa Rican specimens of that species ... -
Illustrations and studies in Neotropical Orchidaceae. 6. The Lepanthes guatemalensis group (Pleurothallidinae) in Costa Rica
(2014)We revise and characterize the group of species close to Lepanthes guatemalensis. The group comprises eight species in Costa Rica. Three new species are described and illustrated. Lepanthes durikäensis is distinguished ... -
