1. Trajectory of NAFLD characteristics after Roux-en-Y gastric bypass: a five-year historical cohort study
Abstract BACKGROUND: The long-term effects of bariatric surgery on the course of non-alcoholic fatty hepatopathy (NAFLD) are not fully understood. OBJECTIVE: To analyze the evolution of NAFLD characteristics through noninvasive markers after Roux-en-Y gastric bypass (RYGB) over a five-year period. DESIGN AND SETTING: Historical cohort study; tertiary-leve

2. EVALUATION OF DIVERSITY AND GENETIC STRUCTURE AS STRATEGIES FOR CONSERVATION OF NATURAL POPULATIONS OF Dalbergia nigra (Vell.) Allemão ex Benth.
ABSTRACT: The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR).

3. Gene pool sharing and genetic bottleneck effects in subpopulations of Eschweilera ovata (Cambess.) Mart. ex Miers (Lecythidaceae) in the Atlantic Forest of southern Bahia, Brazil
Abstract Forest loss and fragmentation are the main threats to the maintenance of the Atlantic Forest, an important global biodiversity hotspot. Because of the current critical level of deforestation, ecological corridors are needed to facilitate species dispersion and gene flow among fragments. This study was conducted to investigate the genetic variability

5. Identification of duplicates in cassava germplasm banks based on single-nucleotide polymorphisms (SNPs)
ABSTRACT: Genetic redundancy in cassava (Manihot esculenta Crantz) presents a challenge to efficient management of genetic resources. This study aimed to identify and define the genetic structure of duplicates in cassava germplasm from various Embrapa research units, using single-nucleotide polymorphism (SNP) markers. We evaluated 2,371 accessions with 20,71

6. Historical evolution of organic matter accumulation in a coastal bay in the SW Atlantic, Brazil: use of sterols and n-alcohols as molecular markers
Os processos de deposição e preservação de matéria orgânica (OM) em sedimentos da Baía de Ilha Grande, sudoeste Atlântico, foram avaliados através de análise elementar (C e N) e de marcadores moleculares (esteróis e n-alcoois). Foram analisadas amostras de quatro testemunhos datados, representando diferentes níveis e tipos de influência antrópi

7. Reconstruction of major maternal and paternal lineages of the Cape Muslim population
The earliest Cape Muslims were brought to the Cape (Cape Town -South Africa) from Africa and Asia from 1652 to 1834. They were part of an involuntary migration of slaves, political prisoners and convicts, and they contributed to the ethnic diversity of the present Cape Muslim population of South Africa. The history of the Cape Muslims has been well documente

8. Genetic diversity and population structure of the Guinea pig (Cavia porcellus, Rodentia, caviidae) in Colombia
The aim was to establish the genetic diversity and population structure of three guinea pig lines, from seven production zones located in Nariño, southwest Colombia. A total of 384 individuals were genotyped with six microsatellite markers. The measurement of intrapopulation diversity revealed allelic richness ranging from 3.0 to 6.56, and observed heterozy

9. Uniparental (mtDNA, Y-chromosome) polymorphisms in French Guiana and two related populations : implications for the region's colonization
Blood samples collected in four Amerindian French Guiana populations (Palikur, Emerillon, Wayampi and Kali’na) in the early 1980s were screened for selected mtDNA and Y-chromosome length polymorphisms, and sequenced for the mtDNA hypervariable segment I (HVS-I). In addition, two other Amerindian populations (Apala´ı and Matsiguenga) were examined for the

12. Estudos de sistemática molecular e de biogeografia histórica do bagre de água doce Pseudoplatystoma Bleeker, 1862 (Pimelodidae) na América do Sul
The catfishes of the Pseudoplatystoma genus are carnivore pimelodids, migratory and important for fisheries in all major river basins from South America. Only three species were recognized for the genus (P. corruscans, P. fasciatum and P. tigrinum), but a new revision raised to eight the number of species (P. fasciatum, P. punctifer, P. orinocoense, P. magda
