1. Prevalence of oral anticoagulation in atrial fibrillation
OBJECTIVES: Atrial fibrillation is the most common sustained arrhythmia and is associated with poor outcomes, including stroke. The ability of anticoagulation therapy to reduce the risk of stroke has been well established; however, the prevalence of anticoagulation therapy use in the Public Health System is unknown. The aim of this study is to evaluate both

2. Presunções em direito tributário: teoria e prática / Presunções no direito tributário: teoria e prática
A matéria das presunções no direito relembra condições da própria gênese do sistema jurídico. Toda linguagem normativa comparece a princípio como raciocínio ou juízo presuntivo simples. No lidar com os casos concretos, primitivamente é o exegeta autêntico que faz introduzir no ordenamento fatos, presumindo ocorrências da realidade empírica. E

3. Laboratorial method validation : evaluation of BAX system Trade Mark for Salmonella sp in food for polymerase chain reaction. / Validação de metodos laboratoriais : avaliação do sistema BAX Marca Registrada de analise de Salmonella sp em alimentos por reação de polimerase em cadeia (PCR).
Salmonella sp is one of most important food born microorganism in all the world, and it always has been focused among international public health organs. The food analysis for this pathogen is a subject of routine in all food quality control laboratories, and, besides there are several alternative methods for Salmonella sp detection, but most of the laborato

4. Biological macromolecules as gels: functional similarities.
Functional biological macromolecules arising from folding, cross-connection, and solvation of long-chain biopolymers forming three-dimensional networks can be compared to gels. Both involve identical internal competitive forces that are selectively influenced by external conditions and conspire to adjust conformations and modulate functions. In spite of impo

5. The location of Z- and W-linked marker genes and sequence on the homomorphic sex chromosomes of the ostrich and the emu
Perhaps the most striking fact about early Cenozoic avian history some 70 million years ago was the rapid radiation of large, flightless, ground-living birds. It has been suggested that, for a time, there was active competition between these large terrestrial birds and the early mammals. Probably reflecting the above noted early start of Ratitae of the infra

6. Detection and Characterization of Plasmid pJP4 Transfer to Indigenous Soil Bacteria
Prior to gene transfer experiments performed with nonsterile soil, plasmid pJP4 was introduced into a donor microorganism, Escherichia coli ATCC 15224, by plate mating with Ralstonia eutropha JMP134. Genes on this plasmid encode mercury resistance and partial 2,4-dichlorophenoxyacetic acid (2,4-D) degradation. The E. coli donor lacks the chromosomal genes ne

7. DNA sequences of the joining regions of mouse lambda light chain immunoglobulin genes.
The joining (J) segments of mouse immunoglobulin lambda light chain genes, lambda 2, lambda 3, and a presumptive lambda 4, were cloned, and their sequences were determined and compared with that of lambda 1. Although all the lambda J segments share sequence homology, the J1 and J4 segments and the J2 and J3 segments, respectively, are more homologous. These

8. Molecular cloning of a DNA fragment from human chromosome 14(14q11) involved in T-cell malignancies.
To isolate DNA segments specific to chromosome band 14q11, which has been implicated in a number of human T-cell malignancies, a genomic DNA library was prepared from a variant cell subline of the human lymphoblastic KE37 cell line. This subline (KE37-R) bears a t(8;14) (q24;q11) translocation, and the breakpoint on the resulting chromosome 8q+ has been loca

9. Isolation and nucleotide sequence of mouse NCAM cDNA that codes for a Mr 79,000 polypeptide without a membrane-spanning region.
The neural cell adhesion molecule (NCAM) exists in several isoforms which are selectively expressed by different cell types and at different stages of development. In the mouse, three proteins with apparent Mr's of 180,000, 140,000 and 120,000 have been distinguished that are encoded by 4-5 different mRNAs. Here we report the full amino acid sequence of a NC

10. Detection and quantification of Vibrio fischeri autoinducer from symbiotic squid light organs.
Vibrio fischeri is the specific light organ symbiont of the sepiolid squid species Euprymna scolopes and Euprymna morsei. Both species of squid are luminescent by virtue of their bacterial symbionts, but the natural symbionts of E. scolopes do not produce visible luminescence in laboratory culture. The primary cause of this depressed luminescence by E. scolo

11. A new gene locus of Bordetella pertussis defines a novel family of prokaryotic transcriptional accessory proteins.
Recently, a novel type of regulatory mutation causing differential effects on the expression of virulence genes due to a slight overexpression of the RNA polymerase alpha subunit (RpoA) was found in Bordetella pertussis (N. H. Carbonetti, T. M. Fuchs, A. A. Patamawenu, T. J. Irish, H. Deppisch, and R. Gross, J. Bacteriol. 176:7267-7273, 1994). To gather info

12. The Metabolism of Oat Leaves during Senescence: I. Respiration, Carbohydrate Metabolism, and the Action of Cytokinins 12
When the detached first leaves of green or etiolated oat (Avena sativa cv. Victory) seedlings senesce in the dark, their oxygen consumption shows a large increase, beginning after 24 hours and reaching a peak of up to 2.5 times the initial rate by the 3rd day. This effect takes place while the chlorophyll of green leaves, or the carotenoid of etiolated leave
