| At worldwide level, the classical viticulture produces wines is almost all places in different climate types, where it is possible to obtain only one harvest per year. In these conditions, bud burst in vines occurs as a result of temperature raising at the end of the winter?beginning of spring. With the development of the vegetative cycle, grapes arrive to maturity/harvest period at the end of the summer?beginning of the fall season. After the fall of the leaves, vines undergo a dormant period with a vegetative repose (condition found also in some intertropical producer regions). A lot of grapes are produced for a long-time in the intertropical zone, but only a little part is used to winemaking. Considered a challenge in the past, to produce quality wines... |

| Este artigo apresenta uma ?Pesquisa-Ação? realizada em uma pesquisa de doutoramento, que utilizou os momentos metodológicos propostos por João Bosco Pinto, sob um referencial do materialismo histórico. Para tanto, o pesquisador-coordenador lançou mão da Teoria das Representações Sociais de Serge Moscovici e outros autores, visando a construção, juntamente com as dez famílias assentadas no Projeto Olga Benário, em Santa Tereza do Oeste, Estado do Paraná, de um determinado conhecimento sobre a área de Reserva Legal (ARL) daquele assentamento, com a finalidade de um possível manejo daquela área em bases sustentáveis. |

| Background: In 2008/2009, Schmidt and colleagues published a study reporting lethal effects of the microbial Bt toxins Cry1Ab and Cry3Bb on the coccinellid biological control organisms Adalia bipunctata. Based on this study, in concert with over 30 other publications, Mon810 cultivation was banned in Germany in 2009. This triggered two commentaries and one experimental study all published in the journal ‘Transgenic Research’ that question the scientific basis of the German ban or claim to disprove the adverse effects of the Bt toxins on A. bipunctata reported by Schmidt and colleagues, respectively. This study was undertaken to investigate the underlying reasons for the different outcomes and rebuts the criticism voiced by the two other commentaries.... |

| Feeding of concentrates to ruminants in organic farming in Switzerland is questionable due to several aspects: (i) suitability for ruminants, (ii) land use change caused by soy cultivation, (ii) organic principles of closed circuits, and (iv) ethical considerations when ruminants directly compete with human nutrition. In the past decades breeding strategies in the dairy sector focused primarily on milk production which led to increased energy requirements. A reduction of concentrates in the ration may thus lead to a more negative energy balance and may be detrimental for health and fertility. Published genotype x feeding system interactions suggest that different breeds, strains or genotypes react differently to different levels of feeding. The aim of... |

| MicroRNAs (miRNAs) are small endogeneous non-coding RNAs of about 22nt length. These short RNAs regulate the expression of mRNAs by hybridizing with their 3'-UTRs or by translational repression. They have been shown to take crucial roles in many biological processes. Many of the current studies are focused over how mature miRNAs regulate mRNAs, even though there is very limited knowledge about their transcriptional loci. Primary miRNAs (pri-miRs) are first transcribed from the DNA, followed by the formation of precursor miRNA (pre-miR) by endonucleases activity, which finally produces mature miRNAs. Unfortunately, the identification of the loci of pri-miRs, and the associated information about transcription start sites (TSSs) and promoters is... |

| RNA-seq technology facilitates the study of gene expression at the level of individual exons and transcripts. Moreover, RNA-seq enables unbiased comparative analysis of expression levels across species. Such analyses typically start by mapping sequenced reads to the appropriate reference genome before comparing expression levels across species. However, this comparison requires prior knowledge of orthology at the exon level. With this in mind, I constructed a database of orthologous exons across three primate species (human, chimpanzee, and rhesus macaque). The database facilitates cross-species comparative analysis of exon- and transcript-level regulation. A web application allowing for an easy database query: http://giladlab.uchicago.edu/orthoExon/ |
