1. The Role of Cartilage-perichondrium Tympanoplasty in the Treatment of Tympanic Membrane Retractions: Systematic Review of the Literature
Abstract Introduction Tympanic retraction is a condition characterized by the displacement of the tympanic membrane toward the structures of the middle ear. Clinically, tympanic retractions can lead to hearing loss, ear discharge and/or ear pain. In most of the cases, however, tympanic retractions are asymptomatic and are found accidentally during an ear, n

2. Estratégias de condução de populações segregantes no melhoramento genético do feijoeiro / Driving strategies of segregating populations applied in genetic improvement of commo bean
In agreement with the convenience of the breeders, some modifications can be made in the traditional methods of conductions of the populations segregating. In bean, a common strategy used by breeders is the aspect selection for grain from early generations. Therefore, the aspect of grains is an important feature to obtain new cultivar. However, there is litt

4. Herança e relações genéticas entre densidade da semente, teores de proteína e óleo e produtividade em soja / Inheritance and genetic relationships among seed density, protein and oil contents and yield in soybean
The high socioeconomic importance of soybean is mainly attributed to its much favorable combination of high protein and oil contents, together with appropriate levels of seed yield. However, there is a high negative correlation between protein and oil contents, fact that difficult the simultaneous breeding of these traits. Besides, also there is tendency of

5. Phenotypic recurrent selection in common bean for resistance to Phaeoisariopsis griseola / SeleÃÃo recorrente fenotÃpica no feijoeiro visando a resistÃncia a Phaeoisariopsis griseola
The present work was carried out to evaluate the efficiency of phenotypic recurrent selection to obtain common bean lines resistant to Phaeoisariopsis griseola. The base population was obtained from a partial diallel cross involving seven parents with carioca-grain type (Carioca MG, CI-140, CI-128, ANPAT 8,12, IAPAR 81, 693 ESAL and PÃrola) and ten sources

6. Estimation of variance components and prediction of breeding values in rubber tree breeding using the REML/BLUP procedure
The present paper deals with estimation of variance components, prediction of breeding values and selection in a population of rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Müell.-Arg.] from Rio Branco, State of Acre, Brazil. The REML/BLUP (restricted maximum likelihood/best linear unbiased prediction) procedure was applied. For this purpose, 37

7. Performance of common bean families after different generations under natural selection
A segregant bulk population derived from a single cross between the Carioca MG cultivar and the ESAL 686 line was used to investigate whether the action of natural selection in the direction required by the breeders and the delaying line extraction would increase the chance of obtaining families with greater grain yield. The populations were advanced from F2

8. Natural selection and the breederâs decision about the best moment to extract families in common bean. / SeleÃÃo natural e a decisÃo do melhorista sobre o melhor momento de abrir o Bulk na cultura do feijoeiro
The âbulkâ method presents some advantages, including the versatility in extracting families at any moment. Theoretically there is no justification in delaying line extraction beyond the F5 generation, but if there is action of natural selection in the direction required by the breeders, a question of whether delaying line extraction would increase the cha

9. Persistent Recognition of Autologous Virus by High-Avidity CD8 T Cells in Chronic, Progressive Human Immunodeficiency Virus Type 1 Infection
CD8 T-cell responses are thought to be crucial for control of viremia in human immunodeficiency virus (HIV) infection but ultimately fail to control viremia in most infected persons. Studies in acute infection have demonstrated strong CD8-mediated selection pressure and evolution of mutations conferring escape from recognition, but the ability of CD8 T-cell

10. Use of different molecular typing techniques for bacteriological follow-up in a clinical trial with AIDS patients with Mycobacterium avium bacteremia.
One hundred ninety-six Mycobacterium avium isolates from blood samples recovered from 93 AIDS patients for several months were typed by serotyping, by IS1245 restriction fragment length polymorphism (RFLP) analysis and in some cases RFLP analysis with plasmids pVT2 and pLR7 as probes, and by pulsed-field gel electrophoresis (PFGE). PCR typing of single colon

11. Emergence of a Cue Strategy Preference on the Water Maze Task in Aged C57B6 × SJL F1 Hybrid Mice
The effects of age on cue learning, spatial reference memory, and strategy preference were assessed in B6 × SJL F1 mice by using the Morris water maze. This mouse strain is of particular interest because it is the background strain for a common transgenic model of Alzheimer's disease, the Tg2576 mouse, which develops plaques and other neurobiological marker
