A distinctive oral phenotype points to FAM20A mutations not identified by Sanger sequencing
(2015-10-04)Biallelic FAM20A mutations cause two conditions where Amelogenesis Imperfecta (AI) is the presenting feature: Amelogenesis Imperfecta and Gingival Fibromatosis Syndrome; and Enamel Renal Syndrome. A distinctive oral phenotype ... -
A genome‐wide quantitative trait locus (QTL) linkage scan of NEO personality factors in Latino families segregating bipolar disorder
(2017)Personality traits have been suggested as potential endophenotypes for Bipolar Disorder (BP), as they can be quantitatively measured and show correlations with BP. The present study utilized data from 2,745 individuals ... -
A Mesoamerican origin of cherimoya (Annona cherimola Mill.): Implications for the conservation of plant genetic resources
(2017)Knowledge on the structure and distribution of genetic diversity is a key aspect to plan and execute an efficient conservation and utilization of the genetic resources of any crop as well as for determining historical ... -
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 ... -

(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 genus and species of gall-inducing thrips (Thysanoptera: Tubulifera) from the neotropical region
(BRENESIA 2008 No. 69, 2008)A new genus of gall-inducing thrips is described for Costa Rica. This taxon seems to be close to Plagiothrips, and can be distinguished by several morphological features, where the most relevant is the presence of an ... -
A new Muricea species (Cnidaria, Anthozoa, Octocorallia) from the eastern tropical Pacific
(2016)The genus Muricea is considered abundant and widely distributed along the eastern Pacific. Its occurrence in shallow waters has been recognised; however species from deeper than 30 m have been rarely recorded. During the ... -
