Reduced genetic diversity and the success of the invasive peacock bass (Cichliformes: Cichlidae)

Luz, S C S; Montes, M A; Farias, R S; Lima, R V; Torres, R A; Ferreira, E J G; Severi, W; Coimbra, M R M.

Braz. j. biol; 84 (), 2024

Abstract Several species of Cichla successfully colonized lakes and reservoirs of Brazil, since the 1960's, causing serious damage to local wildlife. In this study, 135 peacock bass were collected in a reservoir complex in order to identify if they represented a single dominant species or multiple ones, ...

DNA Barcoding unveils cryptic lineages of Hoplias malabaricus from Northeastern Brazil

Pires, W M M; Barros, M C; Fraga, E C.

Braz. j. biol; 81 (4), 2021

Abstract The trahira or wolf fish - Hoplias malabaricus- is a valid species, although recent cytogenetic and molecular studies have indicated the existence of a species complex. In this context, the present study analyzed the mitochondrial COI marker to determine the levels of genetic diversity of specim...

Association of whole mtDNA, an NADPH G11914A variant, and haplogroups with high physical performance in an elite military troop

Santos, C G M; Rolim-Filho, N G; Domingues, C A; Dornelas-Ribeiro, M; King, J L; Budowle, B; Moura-Neto, R S; Silva, R.

Braz. j. med. biol. res; 54 (6), 2021

Physical performance is a multifactorial and complex trait influenced by environmental and hereditary factors. Environmental factors alone have been insufficient to characterize all outstanding phenotypes. Recent advances in genomic technologies have enabled the investigation of whole nuclear and mitocho...

Haplotypes in CCR5-CCR2 , CCL3 and CCL5 are associated with natural resistance to HIV-1 infection in a Colombian cohort

Vega, Jorge A.; Villegas-Ospina, Simón; Aguilar-Jiménez, Wbeimar; Rugeles, María T.; Bedoya, Gabriel; Zapata, Wildeman.

Biomédica (Bogotá); 37 (2), 2017

RESUMEN Introduction: Variants in genes encoding for HIV-1 co-receptors and their natural ligands have been individually associated to natural resistance to HIV-1 infection. However, the simultaneous presence of these variants has been poorly studied. Objective: To evaluate the association of single a...

J. pediatr. (Rio J.); 92 (6), 2016

Abstract Objective: To verify genetic determinants associated with stroke in children with sickle cell disease (SCD). Methods: Prospective cohort with 110 children submitted to neonatal screening by the Neonatal Screening Program, between 1998 and 2007, with SCD diagnosis, followed at a regional refere...

Estudio inmunogenético de una familia cifosis juvenil de Scheuermann

Scheuermann's disease study immunogenetic in one family

Gutiérrez Ulrich, Moisés; Yamamoto Furusho, Jesús K; Burgos Vargas, Rubén; Granados, Julio.

Rev. mex. reumatol; 11 (6), 1996

La enfermedad de Scheuermann es una cifosis torácica baja que se desarrolla en la pubertad, de etiología desconocida y que parece tener un patrón de herencia dominante. Para estudiar la causa genética se reportan aquí los haplotipos presentes en una familia mestiza mexicana con enfermedad de Scheuer...
