13. Analysis of the population structure of Uruguayan Creole cattle as inferred from milk major gene polymorphisms
The ancestors of Uruguayan Creole cattle were introduced by the Spanish conquerors in the XVII century, following which the population grew extensively and became semi-feral before the introduction of selected breeds. Today the Uruguayan Creole cattle genetic reserve consists of 575 animals. We used the tetra primer amplification refractory mutation system p

14. Análise da seleção e segmentação de fornecedores estratégicos em uma cadeia global de valor: estudo de caso em uma empresa multinacional manufatureira de bens de consumo não-duráveis do setor de higiene e limpeza doméstica no Brasil. / Analysis of strategic suppliers selection and segmentation in a global value chain.
The current business environment presents a strong competition in global markets, with cost pressures, focus on new products development with shorter lifetimes than ever and a high customer and clients expectations to have their needs and requirements satisfied. The big fast moving consumer goods companies have already understood these messages, and leverage

15. Desenvolvimento e avaliação de filtro para veia cava inferior stent-filtro.
Implantation of an inferior cava vena filter is recommended for the prevention of pulmonary embolism when anticoagulation fails or is contra-indicated. The aim of this study was to develop and evaluate a new low-cost model of inferior cava vena filter. In reality in this case it is a combination of a inferior cava vena filter with a vascular stent. The mater

16. The Development and Meiotic Behavior of Asymmetrical Isochromosomes in Wheat
To determine which segments of a chromosome arm are responsible for the initiation of chiasmate pairing in meiosis, a series of novel isochromosomes was developed in hexaploid wheat (Triticum aestivum L.). These isochromosomes are deficient for different terminal segments in the two arms. It is proposed to call them ``asymmetrical.'' Meiotic metaphase I pair

17. Effects of variations in length of hammerhead ribozyme antisense arms upon the cleavage of longer RNA substrates.
The efficacy of intracellular binding of hammerhead ribozyme to its cleavage site in target RNA is a major requirement for its use as a therapeutic agent. Such efficacy can be influenced by several factors, such as the length of the ribozyme antisense arms and mRNA secondary structures. Analysis of various IL-2 hammerhead ribozymes having different antisense

18. Direct haplotype determination by double ARMS: specificity, sensitivity and genetic applications.
We have developed a novel double Amplification Refractory Mutation System (double ARMS) using a highly polymorphic region 5' to the human delta-globin gene as a model system. The double ARMS approach involves using two allele-specific ARMS primers simultaneously during DNA amplification by the polymerase chain reaction (PCR). The resulting system is highly s

19. Genetic analysis in cystic fibrosis using the amplification refractory mutation system (ARMS): the J3.11 MspI polymorphism.
A new method of genetic analysis has been devised. The method, amplification refractory mutation system (ARMS), has been used to genotype the J3.11 MspI restriction fragment length polymorphism (RFLP) closely linked to cystic fibrosis (CF). The DNA sequence for both alleles of this dimorphism has been used to design ARMS primers. These allow genotyping of DN

20. Chromosome 9 arm-specific telomere length and breast cancer risk
Background: Telomere dysfunction is involved in the development of breast cancer and very short telomeres are frequent genetic alterations in breast tumors. However, the influence of telomere lengths of specific chromosomal arms on the breast cancer risk is unknown. Methods: We conducted a case–control study of breast cancer to examine the associations of

21. Genome-sized RNA from reovirus particles.
Spider-like forms of purified reovirus RNA have been characterized by electron microscopy. These structures contained 11.3 +/- 0.8 mum of double-stranded RNA and up to 20 arms, each of distinct length. Length measurements of 64 "spiders" suggest that in these structures the viral genome is folded fairly specifically.

22. Centromere mapping and orientation of the molecular linkage map of rice (Oryza sativa L.).
Rice has become a model cereal plant for molecular genetic research. Rice has the most comprehensive molecular linkage maps with more than 2000 DNA markers and shows synteny and colinearity with the maps of other cereal crops. Until now, however, no information was available about the positions of centromeres and arm locations of markers on the molecular lin

23. An efficient procedure for genotyping single nucleotide polymorphisms
Analysis of single nucleotide polymorphisms (SNPs) has been and will be increasingly utilized in various genetic disciplines, particularly in studying genetic determinants of complex diseases. Such studies will be facilitated by rapid, simple, low cost and high throughput methodologies for SNP genotyping. One such method is reported here, named tetra-pr

24. Dynein binds to and crossbridges cytoplasmic microtubules.
Dynein isolated from Chlamydomonas flagellar axonemes binds to microtubules assembled in vitro from 6S brain tubulin dimers. The dynein arms bind periodically along the length of the microtubules with a center-to-center spacing of 24 nm, equal to the periodicity of dynein arms on intact axonemes. The arms project from the in vitro assembled microtubules at a
