1. Transcription factors and molecular markers revealed asymmetric contributions between allotetraploid Upland cotton and its two diploid ancestors
ABSTRACT Three Gossypium species have been used to breed cotton as they vary in their fiber production and resistance to stresses. Transcription factors (TFs) mostly are present in different copies or isoforms by which they conduct their regulation. Their copy number can determine organism behavior to a cue. Simple sequence repeats (SSRs) are one of the most

2. LA ANTROPOLOGÍA DE LA DEMOCRACIA: EL DEMÓCRATA EN LA ORACIÓN FÚNEBRE DE PERICLES
Resumo No presente artigo nos propomos refletir acerca do porquê, na Oração Fúnebre de Péricles, a democracia produz indivíduos qualitativamente superiores aos demais regimes políticos. A conclusão é que, como dignos sucessores da herança de seus antepassados, não somente multiplicaram a herança ampliando o império, senão transformando, também

3. [ARTIGO RETRATADO] O mundo da vida e o mundo do texto em Úrsula, de Maria Firmina dos Reis
Resumo: O romance Úrsula, de Maria Firmina dos Reis (2004), teve sua primeira publicação em 1859. Ele revela sua magnitude por dois aspectos: o primeiro, por ter sido o primeiro romance de autoria afrodescendente da literatura brasileira; o segundo, por ter sido o primeiro romance abolicionista escrito no Brasil. Nele, Maria Firmina dos Reis faz da escrit

4. Distribution of European and African species of genus Diaptomus (Copepoda: Calanoida: Diaptomidae): a track analysis
ABSTRACT The distributional patterns of 13 species of Diaptomus Westwood, 1836 were analyzed using the panbiogeographical method of track analysis. Locality records were compiled from the literature and mapped for the construction of individual tracks for each species. These tracks were superimposed to find the generalized tracks. Four generalized tracks wer

5. Genetic diversity assessment of the Mexican Simmental population through pedigree analysis
ABSTRACT The purpose of this study was to examine the genetic variability of the Mexican Simmental. Inbreeding was calculated by year for animals born from 1985 to 2014. Proportion of ancestors known, average equivalent complete generations, generation interval, and effective size, as well as the effective numbers of founders, ancestors, and founder genomes

6. The dynamics of Brazilian protozoology over the past century
Brazilian scientists have been contributing to the protozoology field for more than 100 years with important discoveries of new species such asTrypanosoma cruzi and Leishmania spp. In this work, we used a Brazilian thesis database (Coordination for the Improvement of Higher Education Personnel) covering the period from 1987-2011 to identify researchers who c

7. Origins of Bipedalism
ABSTRACT This article aimed to review various theories of bipedalism and provide a holistic answer to human evolution. There have been two questions regarding bipedalism: i) why were the earliest hominins partially bipedal?, and ii) why did hominins become increasingly bipedal over the time and replaced their less bipedal ancestors? To answer these questions

8. The genetic base of Brazilian soybean cultivars: evolution over time and breeding implications
Genetic diversity is essential for crop breeding and one way to estimate it is through the concept of genetic base, which can be defined as the number of ancestors and their relative genetic contributions (RGC) to each cultivar. The RGC can be estimated through the coefficient of parentage between the ancestors and cultivars. Previous studies determined that

9. Population structure of Nellore cattle in northeastern Brazil
The objective of this study was to evaluate the population genetic structure of Nellore cattle in northeastern Brazil. Pedigree information was collected from 175,231 animals born from 1967 to 2007. Probability of gene origin, inbreeding, average relatedness coefficient (AR), completeness pedigree, effective population size and generation interval were calcu

10. Genetic structure and a selected core set of brazilian soybean cultivars
Soybean is one of the most valuable and profitable oil crop species and a thorough knowledge of the genetic structure of this crop is necessary for developing the best breeding strategies. In this study, a representative collection of soybean cultivars recommended for farming in all Brazilian regions was genotyped using 27 simple sequence repeat (SSR) loci.

11. Retratos maternos: fotografias e cartas de imigrantes japoneses em São Paulo / Maternal portraits: photographs and letters of Japanese immigrants in São Paulo
This research focused on my maternal grandmother, Akie Sakasegawa Matsuyama, and her families: her parents and siblings (Sakasegawa) and her husband and children (Matsuyama). I did not know my grandfather, Hideo Matsuyama. Maybe this study is a way I found to know a little about his life history. My main focus was on the state of Akie Sakasegawa Matsuyama, e

12. Famílias de santo: as histórias dos ancestrais e os enredos contemporâneos / Saints´ families: the ancestors´ stories and the contemporaries storylines.
A umbanda pode ser considerada uma religião que retrata por meio de seus rituais as raízes africanas de nossa sociedade. A presente pesquisa objetivou investigar a construção de laços afetivos e de filiação nos rituais de uma família de santo umbandista. Para esse efeito, com base na teoria psicanalítica lacaniana examinou-se em que medida a vivênc
