A microbial consortium from a biomixture swiftly degrades high concentrations of carbofuran in fluidized-bed reactors
(2016)An on-farm biopurification system (BPS) biomixture, with proven capacity to degrade carbofuran (CBF) was used as inoculum for a selective-enrichment process to obtain a bacterial consortium capable of using CBF as a sole ... -
A molecular study of Neophyllaphis varicolor (Hemiptera, Aphididae) in Costa Rica
(2019-07)The genus Neophyllaphis (Takahashi) (Aphididae: Neophyllaphidinae) is composed of 18 species; however, in the Americas only nine species have been reported previously. A new species, Neophyllaphis varicolor Miller & ... -
A new method for the detection of phospholipase A2 variants: identification of isozymes in the venoms of newborn and adult Bothrops asper (terciopelo) snakes
(1988)A new method for the identification of phospholipase A2 isozymes in snake venoms is described. The technique is based on the separation of the venom components by isoelectric focusing in agarose gels, transfer of the protein ... -
A new species of Rhopalosiphum (Hemiptera, Aphididae) on Chusquea tomentosa (Poaceae, Bambusoideae) from Costa Rica
(2012-01)The new species Rhopalosiphum chusqueae Pérez Hidalgo & Villalobos Muller, is described from apterous viviparous females caught on Chusquea tomentosa in Cerro de la Muerte (Costa Rica). The identity of the species is ... -
A schizophrenia gene locus on chromosome 17q21 in a new set of families of mexican and central american ancestry: evidence from the NIMH genetics of schizophrenia in latino populations study
(Am J Psychiatry 2009;166:442-449, 2009-02-02)The present study investigated a new set of families of Latin American ancestry in order to detect the location of genes predisposing to schizophrenia and related psychotic disorders. Method: A genome-wide scan was performed ... -
A time- and cost-effective strategy to sequence mammalian Y Chromosomes: an application to the de novo assembly of gorilla Y
(2016-02)The mammalian Y Chromosome sequence, critical for studying male fertility and dispersal, is enriched in repeats and palindromes, and thus, is the most difficult component of the genome to assemble. Previously, expensive ... -
Absolute pitch in Costa Rica: Distribution of pitch identification ability and implications for its genetic basis
(2016-08-10)Absolute pitch is the unusual ability to recognize a pitch without an external reference. The current view is that both environmental and genetic factors are involved in the acquisition of the trait. In the present study, ... -
Adaptación de una técnica de inmunosorbencia (ELISA) a la detección del virus del rayado fino del maíz en su insecto vector
(1983-06)An enzyme-linked immunosorbent assay (ELISA) was adapted for detection of maize rayado fino virus (RFV) in its insect vector Dalbulus maidis. Optimization of experimental conditions for the assay included the use of ... -
Adjudicating Neurocognitive Endophenotypes for Schizophrenia
(American Journal of Medical Genetics Part B (Neuropsychiatric Genetics) 144B:242–249 (2007), 2007-03-05)Although genetic influences on schizophrenia are well established, localization of the genes responsible for this illness has proven extremely difficult. Given evidence that genes predisposing to schizophrenia may be ... -
Aging of biomixtures: Effects on carbofuran removal and microbial community structure
(2017)The aim of this work was to determine the efficiency of a straw/compost/soil biomixture for pesticide depuration during its aging and continuous use, for a period of over a year, based on its capacity to remove carbofuran ... -
Algunos factores que afectan la transmisión del virus del rayado fino del maíz por Dalbulus maidis DeLong & Wolcott
(1974)Previous reports have shown that the leafhopper Dalbulus maidis transmits rayado fino virus (RFV) of maize in a manner characteristic of viruses that multiply in their insect vectors. Further studies of the virus vector ... -
