1. Caracterização molecular de recombinantes intersubtipos do vírus da imunodeficiência humana tipo 1(HIV-1) em pacientes provenientes da epidemia do estado de São Paulo. / Molecular characterization of recombinant intersubtipos of human immunodeficiency virus type 1 (HIV-1) in patients from the epidemic in the state of Sao Paulo, Brazil.
The extensive HIV-1 genetic diversity has several implications on the viral adaptive and evolutionary capabilities. This diversity is due to intensive mutational rates derived from error-prone activity of viral reverse transcriptase and RNA genomic instability, generating a highly diverse and heterogeneous viral population named quasispecies. However, even t

2. Desempenho de famílias de feijoeiro comum obtidas por diferentes métodos de condução de populações segregantes. / Performance of families of common bean obtained by different methods for conducting.
O feijoeiro comum (Phaseolus vulgaris L.) destaca-se no Brasil por sua importância econômica e, sobretudo social, sendo uma importante fonte de fibra na dieta habitual. Conhecer a variabilidade genética para teor de fibra em feijoeiro comum é muito importante, pois pode garantir o sucesso de programas de melhoramento, avaliando-se a eficiência relativa

4. Eficiência de métodos de condução de população segregante de feijoeiro comum para teor de proteína. / Efficiency evaluation of conducting methods for segregant population of common bean by the protein meaning
The common bean (Phaseolus vulgaris L.) is part of the daily diet of more than 300 million people worldwide, being an essential food for low income human populations, since it is a cheaper protein source. The beans protein content can be improved by breeding programs since the existence of genetic variability for this character can be explored. It is importa

5. Eficiência de métodos de condução de população segregante de feijoeiro comum para teor de proteína. / Efficiency evaluation of conducting methods for segregant population of common bean by the protein meaning
O feijão (Phaseolus vulgaris L.) participa da dieta de mais de 300 milhões de pessoas no mundo, sendo alimento essencial para populações carentes, pois é fonte barata de proteína. O teor de proteína total de feijão pode ser melhorado com o auxílio de programas de melhoramento, já que existe variabilidade genética a ser explorada para esse caráter

6. A search for RNA insertions and NS3 gene duplication in the genome of cytopathic isolates of bovine viral diarrhea virus
Calves born persistently infected with non-cytopathic bovine viral diarrhea virus (ncpBVDV) frequently develop a fatal gastroenteric illness called mucosal disease. Both the original virus (ncpBVDV) and an antigenically identical but cytopathic virus (cpBVDV) can be isolated from animals affected by mucosal disease. Cytopathic BVDVs originate from their ncp

7. Componentes da variÃncia fenotÃpica em feijoeiro utilizando o mÃtodo genealÃgico / Phenotypic variance components in beans by the pedigree method.
In the present work the pedigree method was used to estimate the phenotypic variance components for grain yield and plant habit. A segregating population from the cross between BRS TalismÃ, (growing habit III, carioca grain type) and BRS Valente (growing habit II and black grain) was used. Sixty-four plants were randomly sampled from the F2 to generate F2:3

8. Gene targeted DNA double-strand break induction by (125)I-labeled triplex-forming oligonucleotides is highly mutagenic following repair in human cells.
A parallel binding motif 16mer triplex-forming oligonucleotide (TFO) complementary to a polypurine-polypyrimidine target region near the 3'-end of the SupF gene of plasmid pSP189 was labeled with [5-(125)I]dCMP at position 15. Following triplex formation and decay accumulation, radiation-induced site-specific double-strand breaks (DSBs) were produced in the

9. Length Regulation and Dynamics of Individual Telomere Tracts in Wild-Type Arabidopsis
Although length of the telomeric DNA tract varies widely across evolution, a species-specific set point is established and maintained by unknown mechanisms. To investigate how telomere length is controlled in Arabidopsis thaliana, we analyzed bulk telomere length in 14 wild-type accessions. We found that telomere tracts in Arabidopsis are fairly uniformly di

10. Microarray-based rapid cloning of an ion accumulation deletion mutant in Arabidopsis thaliana
Here we describe the development of a microarray-based mapping strategy to rapidly isolate deletion mutant genes. The presented approach is particularly useful for mapping mutant genes that are difficult to phenotype. This strategy uses masking bulk segregant analysis to mask unrelated deletions, thus allowing identification of target deletions by microarray

11. Metabolism and transport of strontium in giant axons of Loligo.
1. The strontium content of squid axons averages 2.9 mumol kg-1 axoplasm and squid blood contains 75 mumol Sr l-1. The bulk of the Sr inside axons is bound, possibly within mitochondria. Sr seems to be handled by squid axons in an essentially similar manner to Ca. 2. Sr uptake is increased by electrical activity, by lowering external Na, by depolarization wi

12. Near-membrane [Ca2+] transients resolved using the Ca2+ indicator FFP18.
(Ca2+)-sensitive processes at cell membranes involved in contraction, secretion, and neurotransmitter release are activated in situ or in vitro by Ca2+ concentrations ([Ca2+]) 10-100 times higher than [Ca2+] measured during stimulation in intact cells. This paradox might be explained if the local [Ca2+] at the cell membrane is very different from that in the
