1. Selection of parents for low nitrogen stress through the combining ability of maize partially inbred lines
ABSTRACT. The objective of this work was to estimate the general combining ability of partially inbred lines under high and low nitrogen (N) conditions and to select promising lines to obtain high yields for both conditions. Fifty-five partially inbred S1 progenies were evaluated using the top-cross method, where the lines were crossed with two testers. The

2. Genetic diversity, population structure and AFLP markers associated with maize reaction to southern rust
ABSTRACT Maize is one of the species with greater genetic diversity among cereals and possibly the most diverse crop species known. Accessing this variability is essential for maize breeding, allowing breeders to achieve progress of yield increasing, overcome environmental challenges or deal with pests and diseases. Among the maize diseases, southern rust is

3. Working closely with corpora. Proposta de ensino de colocações adverbiais em inglês para negócios, sob a luz da Linguística de Corpus / Working closely with corpora. A proposal for teaching typical adverbial collocations in Business English, based on Corpus Linguistics principles
O objetivo deste trabalho é apresentar uma proposta para o ensino de colocações adverbiais em inglês, típicas da área de negócios, à luz da Linguística de Corpus. Para isso, compilamos um corpus monolíngue em inglês britânico e americano, composto de periódicos de negócios e relatórios de empresas disponíveis on-line, num total de 2.310.143 p

4. Adequação da demanda atendida em serviço de urgência de média complexidade em Londrina, Paraná, Brasil
Hierarchy in health care follows a bottom-up flow that starts at the level of lower complex services. Nevertheless, studies have shown that this is a system with frail organization and flow deviations. Thus, emergency services are highly demanded and lead to long waiting lines and a high percentage assistance of inadequate cases. Due to the scarce research o

5. Molecular characterization of a cryptic wheat-Thinopyrum intermedium translocation line: evidence for genomic instability in nascent allopolyploid and aneuploid lines
A putative translocation line (#32), together with a disomic addition line (TAI27) and an octo-amphiploid line (Zhong3) of common wheat and Thinopyrum intermedium were characterized by restriction fragment length polymorphism (RFLP) analysis, using probes covering all seven homoeologous groups of Triticeae. Line 32 was confirmed to be a cryptic translocation

6. In Vivo Interaction of Endotoxin with a Plasma Lipoprotein Having Esterase Activity
Circulating endotoxin was specifically precipitated from plasma samples withdrawn from three different animal species subsequent to parenteral injection of the toxin. Lipoprotein-positive staining and esterase activity were demonstrated on the precipitation lines formed in immunodiffusion, thus establishing the in vivo interaction of endotoxin with a plasma

7. Susceptibilities of Herpes Simplex Viruses to Penciclovir and Acyclovir in Eight Cell Lines
The commonly used antiviral drugs acyclovir (ACV) and penciclovir (PCV) possess similarly potent antiviral activities in vivo against herpes simplex virus (HSV). Assay methods for sensitivity to ACV are not necessarily transferable to PCV, even though the two drugs have similar in vivo potencies and mechanisms of action. We determined by plaque reduction ass

8. Electrophoretic analysis of human HLA-DR antigens from HLA-DR4 homozygous cell lines: correlation between beta-chain diversity and HLA-D.
Two-dimensional gel electrophoresis of immunoprecipitated human HLA-DR antigens from cells expressing the HLA-DR4 haplotype shows distinct clustering of beta-chain patterns. Six unique electrophoretic variants were observed among 17 HLA-DR4 homozygous cell lines (HCL) analyzed. These patterns correlate precisely with the HLA-D phenotype of the HCL donor as d

9. The nucleotide changes governing cuticular hydrocarbon variation and their evolution in Drosophila melanogaster
The cuticular hydrocarbon (CH) pheromones in Drosophila melanogaster exhibit strong geographic variation. African and Caribbean populations have a high ratio of 5,9 heptacosadiene/7,11 heptacosadiene (the “High” CH type), whereas populations from all other areas have a low ratio (“Low” CH type). Based on previous genetic mapping, DNA markers wer

10. Interindividual concordance of methylation profiles in human genes for tumor necrosis factors alpha and beta.
The DNA in mammalian genomes is characterized by complex patterns of DNA methylation that reflect the states of all genetic activities of that genome. The modified nucleotide 5-methyldeoxycytidine (5mdC) can affect the interactions of specific proteins with DNA sequence motifs. The most extensively studied effect of sequence-specific methylations is that of

11. Rapid hybrid speciation in wild sunflowers
Hybrid or “recombinational” speciation refers to the origin of a new homoploid species via hybridization between chromosomally or genetically divergent parental species. Theory predicts that this mode of speciation is punctuated, but there has been little empirical evidence to support this claim. Here, we test the hypothesis of rapid hybrid speciation by

12. Radiation hybrid mapping of the zebrafish genome
The zebrafish is an excellent genetic system for the study of vertebrate development and disease. In an effort to provide a rapid and robust tool for zebrafish gene mapping, a panel of radiation hybrids (RH) was produced by fusion of irradiated zebrafish AB9 cells with mouse B78 cells. The overall retention of zebrafish sequences in the 93 RH cell lines that
