13. Estudos evolutivos em Myrtaceae : aspectos citotaxonomicos e filogeneticos em Myrteae, enfatizando Psidium e generos relacionados
Myrtaceae is one of the most diverse families in Neotropical region; principally belong to Mata Atlântica and Cerrado, reaching 10 to 15% of biodiversity of these biomes. Myrteae is the most generically tribe (73 genera and 2375 species) in this family. Generally, South-American taxa are considered a complex group and biosystematic studies are necessary to

14. Diversidade GenÃtica Populacional nas espÃcies pioneiras Cyperus ligularis L. C. oduratus L. (Cyperaceae) e Miconia prasina (Sw.) dc. (Melastomataceae) ocorrentes em remanescentes da Floresta AtlÃntica de Pernambuco detectada pelos marcadores moleculares DAF e ISSR
The Atlantic Forests have suffered continuous reductions resulting in urgent need of new strategies for its preservation and for the understanding of the fragmentation consequences, especially aiming its preservation. Regarding this scenario, the plant families Cyperaceae and Melastomataceae play an important role, due to its function as pioneers and forest

15. Inclusion of genetic relationship information in the pedigree selection method using mixed models
We used a mixed model approach and computer simulation to evaluate the inclusion of parentage information as determined by the genealogy established in the pedigree method. The simulations were based on a purely additive genetic model for one quantitative trait of 20 unlinked segregating loci with equal effects and an allelic frequency of 0.5 for heritabilit

16. Disturbios do desenvolvimento cortical e epilepsia autossomica dominante com auras auditivas : estudos geneticos e moleculares / Malformations of cortical development and autosomal dominant partial epilepsy with auditory features
Temporal Lobe Epilepsy (TLE) and malformations of cortical development (MCD) are two of the most important causes of epilepsy. Extensive molecular genetic studies have resulted in gene discovery for MCD such as periventricular nodular heterotopia (PNH), lisencephaly/ subcortical band heterotopia spectrum (LIS-SBH), schizencephaly, polymicrogyria and for a su

17. Influence of point variants of pattern recognition receptors in the susceptibility to human malaria / Influência de variantes de receptores de reconhecimento padrão na suscetibilidade à malária
Malaria is one of the major causes of disease and death worldwide, mainly of children. It is also the strongest known force for evolutionary selection in the recent history of the human genome. Besides environmental and parasite factors, host genetic factors play a major role in determining both susceptibility to malaria and the course of infection. Innate i

18. Characterization of ndh gene of isoniazid resistant and susceptible Mycobacterium tuberculosis isolates from Brazil
Resistance in Mycobacterium tuberculosis to isoniazid (INH) is caused by mutations in the catalase-peroxidase gene (katG) , and within the inhA promoter and/or in structural gene. A small percentage (~ 10%) of INH-resistant strains do not present mutations in both of these loci. Other genes have been associated with INH resistance including the gene encoding

19. Dental anomalies as phenotypic extension of oral clefts: molecular studies of candidate genes and chromosomal regions / Anomalias dentárias como extensão fenotípica das fissuras orais: estudos moleculares de genes e regiões candidatas
Cleft lip with or without cleft palate (CL/P) is a common craniofacial anomaly in humans, and may occur as part of a syndrome or isolated, when the affected individuals do not present any associated structural anomalies. The etiology of CL/P is complex, with both genetic and environmental factors involved. Several genes/loci have been suggested in the past y

20. QTL identification in bovine chromosomes 10, 11 and 12 associated with heat stress / Identificação de QTL nos cromossomos 10, 11 e 12 associados ao estresse calórico em bovinos
Heat stress impacts greatly animal production systems on tropical regions causing economical losses and affects milk production, meat production, physiology, reproduction, calf mortality and utter health. One way to reduce these losses is to use the genetic variation between Bos taurus and Bos indicus breeds for heat tolerance coupled with linked molecular m

21. ESTUDO DA VARIABILIDADE GENÉTICA DO CARDINAL (OSTARIOPHYSI: CHARACIFORMES: Paracheirodon axelrodi) NA BACIA DO RIO NEGRO
The cardinal tetra Paracheirodon axelrodi is the most exported Amazonian characin. Since the mid-1950s, cardinal tetras have been harvested along their natural distribution in the Negro, and the upper Orinoco River drainages and their tributaries in Brazil, Colombia and Venezuela. Just the cardinal tetra constitutes over 80% of total catch all ornamental fis

22. IncorporaÃÃo da informaÃÃo de parentesco no mÃtodo genealÃgico pelo enfoque de modelos mistos / Using relationship information from pedigree method on mixed model estimation
In the pedigree method it is usually spent an additional effort for recording the genealogies along the generations, that have been attributed little usefulness. This study aimed to evaluate the efficiency of the pedigree method considering the use of relationship among progenies and to compare its performance with the bulk method by computer simulation and

23. Esterase-D and chromosome patterns in Central Amazon piranha (Serrasalmus rhombeus Linnaeus, 1766) from Lake Catalão
This study presents additional genetic data on piranha (Serrasalmus rhombeus Linnaeus, 1766) complex previously diagnosed due to the presence of distinct cytotypes 2n = 58 and 2n = 60. Three esterase-D enzyme loci (Est-D1, Est-D2 and Est-D3) were examined and complemented with chromosomal data from 66 piranha specimens collected from Lake Catalão. For all s

24. Identificação e caracterização de transcritos associados ao desenvolvimento e crescimento da musculatura esquelética em frangos (Gallus gallus) / Identification and characterization of transcripts associated with skeletal muscle development and growth in chicken (Gallus gallus)
by animal breeding programs along the years based on the observation of adult phenotypic characters. But, the number of myogenic precursor cells and, consequently, the number of muscle fibers is determined during the embryonic stages of development. Therefore, the embryonic myogenic program is an ideal target for searching potential candidate-transcripts, th
