13. Sarcoidosis and chronic hepatitis C: treatment with prednisone and colchicine
Abstract Sarcoidosis is a disease which still has uncertain etiology. Possible environmental causes are cited in the literature, like organic and inorganic particles and infectious agents. Recent studies have demonstrated the occurrence of sarcoidosis in patients with chronic C hepatitis; however, this association remains without statistical or causal eviden

14. Obtaining tetraploid plants of ruzigrass (Brachiaria ruziziensis)
The objective of the present work was to induce chromosome doubling in genotypes of Brachiaria ruziziensis with potential for production of good-quality biomass and tolerance/resistance to stress caused by aluminum and spittlebugs. Germinated seeds of B. ruziziensis were immersed in 0.1% colchicine solution for 2 or 3 hours. Ploidy level was determined by fl

15. Synthesis and biological evaluation of biaryl analogs of antitubulin compounds
This paper reports the synthesis of methanones and esters bearing different substitution patterns as spacer groups between aromatic rings. This series of compounds can be considered phenstatin analogs. Two of the newly synthesized compounds, 5a and 5c, strongly inhibited tubulin polymerization and the binding of [³H] colchicine to tubulin, suggesting that,

16. Vitamin D status in patients with Behcet's Disease
OBJECTIVES: This study investigated the serum 25-hydroxyvitamin D levels of patients with Behcet's Disease. DESIGN AND METHODS: Thirty-two patients with Behcet's Disease and 31 matched healthy controls were enrolled in this study. The erythrocyte sedimentation rate (ESR) and the levels of C-reactive protein (CRP), serum 25-hydroxyvitamin D, calcium (Ca), pho

17. Systemic treatment in severe cases of recurrent aphthous stomatitis: an open trial
PURPOSE: This study aimed to evaluate the efficacy of the systemic drugs thalidomide, dapsone, colchicine, and pentoxifylline in the treatment of severe manifestations of RAS. METHODS: An open, 4-year clinical trial was carried out for 21 consecutive patients with severe RAS. Initially, patients were given a 2-week course of prednisone to bring them to a bas

18. Obtenção de plantas autotetraplóides de variedades de porta-enxertos de citros / Obtention of autotetraploids plants of varieties of rootstocks of Citrus
The Brazilian citriculture stands out as the greatest expression worldwide, with about 27.9% of world production of oranges and 59% of global production of frozen orange juice concentrate. However, it presents a vulnerability that is the predominance of a single species of rootstock, the Cravolemon, with approximately 85% of citrus planted on it. Thus, great

19. Autotetraploidy induction and identification in banana (Musa spp.) / INDUÃÃO E IDENTIFICAÃÃO DE POLIPLOIDIA EM Musa acuminata, Colla
The aimed study to induct and to identify polyploidys identification through stomatal analysis, chromosome counting and flow cytometry, as well polyploidys and mixoploids effects on the structural and ultrastructural characteristics in banana varieties: Malbut, Ouro, Lidi e Thong Dok Mak. In polyploidys induction, explants were treated with concentrations of

20. ObtenÃÃo de hÃbridos hexaplÃides e anÃlise genÃmica de Pennisetum sp por citometria de fluxo / Obtaining hexaploids hybrids and genomic analysis of Peniisetum sp. by flow cytometry
No melhoramento de Pennisetum, a hibridaÃÃo interespecÃfica entre o capim elefante (Pennisetum purpureum) e o milheto (Pennisetum galucum) Ã uma das alternativas para a obtenÃÃo de cultivares superiores. Este hÃbrido (triplÃide) apresenta uma grande limitaÃÃo para o seu uso nos programas de melhoramento, a infertilidade que leva a necessidade de su

21. InduÃÃo de tetraplÃides e alongamento de plantas de Dendrobium nobile Lindl. (Orchidaceae. / Tetraploids induction and elongation of Dendrobium nobile Lindl. plants (Orchidaceae).
The present study was developed at the campus of the Universidade Federal de Lavras, Minas Gerais, over period from January of 2003 to February of 2005, aiming at, for Dendrobium nobile Lindl., the induction and polyploidys identification, the stomatal analysis in diploid (2n=2x=38) and tetraploids (2n=4x=76) leaves, as well as the plant elongation with gibb

22. MicropropagaÃÃo e duplicaÃÃo cromossÃmica de hÃbridos triplÃides de capim-elefante e milheto / MicropropagaÃÃo e DuplicaÃÃo CromossÃmica de HÃbridos TriplÃides de Capim-elefante &Milheto.
Interspecific triploid (3x) hybrids, obtained through the combination of elefant-grass (2n = 4x = 28) with pearl milet (2n = 2x = 14) can overcome their ancestors in production and forage quality. Therefore, they are an alternative to obtain superior cultivars, contributing to increase the production and profit in milk production. However, the greatest limit

23. Cruzabilidade entre espécies silvestres de Arachis visando à introgressão de genes de resistência a doenças no amendoim cultivado. / Crossability among wild species of Arachis for introgression of disease resistance genes into cultivated groundnut.
Groundnut (Arachis hypogaea) is one of the most important oil species in the world. In 2002, Brazil produced about 190 thousand tonelades, with 80 per cent of cultivated area concentrated in the State of São Paulo. The main problem in crop management in this State and in many other growing areas in the world is represented by fungal diseases. Several specie

24. Cytogenetics and immature embryo culture at Embrapa Trigo breeding program: transfer of disease resistance from related species by artificial resynthesis of hexaploid wheat (Triticum aestivum L. em. Thell)
Worldwide wheat (Triticum aestivum L. em. Thell, 2n = 6X = 42, AABBDD) breeding programs aim to reorganize genotypes to achieve better yields, environmental adaptation and food quality. The necessary interdisciplinarity for breeding purposes requires an accurate choice of the most appropriate cellular and/or molecular strategies available to be integrated wi
