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 ... -
Identificación de variantes raras de número de copias en una familia con alta prevalencia de psicosis
(2023)Los trastornos psiquiátricos son enfermedades que afectan los procesos afectivos y cognitivos de las personas y que están presentes en todas las poblaciones humanas. Son padecimientos complejos para los cuales se han ... -
Identification of Anziaic Acid, a Lichen Depside from Hypotrachyna sp., as a New Topoisomerase Poison Inhibitor
(2013)Topoisomerase inhibitors are effective for antibacterial and anticancer therapy because they can lead to the accumulation of the intermediate DNA cleavage complex formed by the topoisomerase enzymes, which trigger cell ... -
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 ... -
Identification of polyphenols from antiviral Chamaecrista nictitans extract using high-resolution LC–ESI–MS/MS
(2014)Chamaecrista nictitans (L) extract possesses antiviral properties; it acts against the herpes simplex virus, and this may be attributed to its constituent phenolics. Here, high-resolution LC–ESI–MS/MS is used to identify ... -
Identification of Protein Kinase C Activation as a Novel Mechanism for RGS2 Protein Upregulation through Phenotypic Screening of Natural Product Extracts
(2014)Biochemical high-throughput screening is widely used in drug discovery, using a variety of small molecule libraries. However, broader screening strategies may be more beneficial to identify novel biologic mechanisms. In ... -
Identification of tropical cyclones’ critical positions associated with extreme precipitation events in Central America
(2021-04)Tropical cyclones are one of the most important causes of disasters in Central America. Using historical (1970–2010) tracks of cyclones in the Caribbean and Pacific basin, we identify critical path locations where these ... -

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 ... -

(2020)This paper focuses on the taxonomy and systematics of the species related to Specklinia brighamii and S. simmleriana in Costa Rica. The group also includes S. alexii, recorded for the first time for the country, S. acrisepala, ... -
Illustrations and Studies in Neotropical Orchids. 2. A note on Pleurothallis luctuosa (Orchidaceae: Pleurothallidinae), with a new species
(2010)The identity of Pleurothallis luctuosa, its taxonomic history and geographic distribution are discussed, and the species is described and illustrated. A new species from Costa Rica, P. neglecta, is described and illustrated. ... -
Imaginaries, invariant types and pseudo p-adically closed fields
(2019-04-29)In this paper, we give a general criterion for elimination of imaginaries using an abstract independence relation. We also study germs of definable functions at certain well-behaved invariant types. Finally we apply these ... -
