1. Some aspects of chicken behavior and welfare
Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the

2. Control of branch formation in ethylene polymerization by a [Ni(eta3-2-MeC3H4)(diimine)] PF6/DEAC catalyst system
A polimerização de etileno em presença do precursor catalítico [Ni(3-2-MeC3H4)- {ArN=C(H)C(H)=NAr}]PF6, Ar = 2,6-C6H3 iPr2/DEAC sob condições reacionais brandas (temperatura de reação entre -10 °C e 25 °C e pressão de etileno entre 109 e 1520 kPa) conduz à formação de polietileno ramificado de alto peso molecular. A taxa de ramificação foi

4. Efeitos agudos do exercício cardiovascular sobre os níveis serotoninérgicos e perfil antropométrico e psicométrico de idosas ativas
Purposes: 1) Identify volunteers anthropometric (AS) and psychometric (PS) status and, 2) verify the dose-response effects of cardiovascular physical exercise of different intensities and duration, on the peripheral alterations of the serotoninergic system, through serotonin (5-HT) and tryptophan (TRP) concentrations and the possible central alterations, thr

5. Polimerização de eteno em altas pressões e temperaturas utilizando catalisadores níquel-alfa-diimina
O complexo 1,4-bis(2,6-diisopropilfenil)-acenaftenodiimina-dicloroníquel(II) (1), em combinação com metilaluminoxano (MAO) foi utilizado para polimerizar eteno utilizando altas pressões e temperaturas. Foram investigados os efeitos da pressão de eteno, da temperatura, do tempo de reação e da quantidade de catalisador bem como, as propriedades dos poli

7. Targeted gene walking polymerase chain reaction.
We describe a modification of a polymerase chain reaction method called 'targeted gene walking' that can be used for the amplification of unknown DNA sequences adjacent to a short stretch of known sequence by using the combination of a single, targeted sequence specific PCR primer with a second, nonspecific 'walking' primer. This technique can replace conven

9. Cloning of the shark Po promoter using a genomic walking technique based on the polymerase chain reaction.
We have cloned the putative shark promoter of protein zero (Po) using a novel application of the ligation mediated single-sided polymerase chain reaction (PCR) method. This method uses linker ligation and subsequent amplifications with a linker primer and multiple specific primers to generate specificity. The method allowed us to amplify approximately 305 ba

10. Targeted gene walking by low stringency polymerase chain reaction: assignment of a putative human brain sodium channel gene (SCN3A) to chromosome 2q24-31.
We have developed a low stringency polymerase chain reaction (LSPCR) to isolate the unknown neighboring region around a known DNA sequence, thus allowing efficient targeted gene walking. The method involves the polymerase chain reaction (PCR) with a single primer under conditions of low stringency for primer annealing (40 degrees C) for the first few cycles

11. Direct genomic sequencing of bacterial DNA: the pyruvate kinase I gene of Escherichia coli.
The genomic sequencing procedure is applied to the direct sequencing of uncharacterized regions of bacterial DNA by a "multiplex walking" approach. Samples of bulk Escherichia coli DNA are cut with various restriction enzymes, subjected to chemical sequencing degradations, run in a sequencing gel, and transferred to nylon membranes. When a labeled oligomer i

12. Change in the signal-response sequence responsible for asymmetric isolation between Drosophila planitibia and Drosophila silvestris.
Drosophila planitibia and Drosophila silvestris form a species pair that is an example of species diverged through a founder event. These species exhibit asymmetric sexual isolation, courtships between D. planitibia males and D. silvestris females being more successful than courtships between D. silvestris males and D. planitibia females. When analyzing the
