    Mapping and stability of QTLs for seed weight in common beans under different environments.

    The objectives were: 1 - to identify, under different environments, RAPD markers linked to loci that control the 100 seed weight of common beans; 2 - to evaluate the existence of interactions involving QTL's with planting dates and locations; 3 - to compare detection procedures of markers linked to QTL's utilizing the methods of mapping and multiple regression. One hundred and minety-six recombinant inbred lines derived from the cross of cultivars Carioca x Flor de Mayo were evaluated under two tradtional sowing dates for common beans in 1996, 1997 and 1998, in Lavras and Patos de Minas, Brazil. For the phenotypic evaluation of the families, seven field experiments were conduced. The experimental design used was a 14 x 14 partially balanced Square Simple Lattice. Results indicated that interaction of QTL's by location were significant, and some stable QTL's were identified. Multiple regression analysis identified a greater number of QTL's-linked markers than the process of composite interval mapping. There was no coincidence between results obtained with the two methods studied. Molecular markers which were considered of greater potential use on marker-assisted selection for seed weight were OPN-02 (1445 pb) e OPM-06 (1096 pb)

    A mamoneira (Ricinus communis L.) é uma planta oleaginosa de elevado potencial energético e de grande importância socioeconômica para o Nordeste. Apresenta-se como fonte energética alternativa ao petróleo e seus derivados, além de apresentar uma alta capacidade de adaptação às diferentes condições ambientais.Em paralelo aconteceram também os seguintes eventos: V Seminário de Pesquisa do Recôncavo da Bahia; V Seminário Estudantil de Pesquisa da UFRB; V Seminário da Pós-Graduação da UFRB; II Seminário Regional de Pesquisa da EBDA; 5ª Jornada Científica da Embrapa Mandioca e Fruticultura; VIII Seminário Estudantil de Pesquisa e Extensão da FAMAM; Semana de Ciência, Tecnologia e Inovação no Agronegócio; Fórum de Gestores de Iniciação Científica e Tecnológica da Bahia; II Simpósio Baiano de Defesa Agropecuária; I Semana de Educação Tutorial da UFRB

    Proposal of a New Standardized Freeze-Thawing Technical Protocol for Leucocyte-Poor Platelet-Rich Plasma Preparation and Cryopreservation

    A human platelet-rich plasma (PRP) concentrate can be defined as a preparation of autologous human plasma with increased platelet concentration produced by centrifugation of a larger volume of a patient's own blood. Platelets contain a plethora of growth factors in their α-granules that are concentrated through the centrifugation process in order to then be injected in supraphysiologic amounts to an injury site with the final aim of augmenting the natural healing process. Preparations of PRP concentrates can be further classified as leucocyte-rich (LR-PRP), defined as having a leucocyte concentration above baseline, and leucocyte-poor (LP-PRP), defined as having a leucocyte concentration below baseline. Although many preclinical and clinical trials have shown the ability of leucocyte-poor PRP concentrates to significantly improve symptomatic mild to moderate hip and/or knee osteoarthritis, to date there is no consensus on the optimal way of obtaining PRP preparations, specifically with respect to the concentration of blood components. In this technical report, we describe a new standardized freeze-thawing technique for leucocyte-poor PRP preparation and cryopreservation, which has been shown to be superior to currently available techniques based solely on centrifugation. By describing this technical protocol, which we have been using on a daily basis in the setting of a Regenerative Medicine Outpatient Clinic in a European tertiary university hospital center, we aim to contribute to a future consensus on the optimal way of obtaining and preserving leucocyte-poor PRP concentrates.info:eu-repo/semantics/publishedVersio
