Proteômica para investigar a congelabilidade do semen bovino

The present study was undertaken the protein composition in 2D-electrophoretic pattern (2DE) of the seminal plasma (SP) can interfere in the semen bull freezability, and if we can use that for predicting semen bull freezability. Samples were obtained of 20 bulls (different breeds) with a minimum of 3 years history semen production in commercial semen collection Center. All animals ranged between 2 - 7 years of age. The semen freezability was calculated by # of thawed and approved ejaculates / # of ejaculates submitted to cryopreservation (after semen evaluation and approved to submitted to freeze). The bulls were divided in 3 groups: HIGH (=>80% ejaculates approved); MEDIUM (>60% and <79% ejaculates approved); LOW (=<59% ejaculates approved); the pattern and criteria were the same used in the routine of the commercial semen Center. 68 gels were carried through by 2DE of SP samples indicated 225 detected spots with protein different amount (VION) comparing. Comparing bull ́s semen freezability and VION of each spot found difference among 2 spots from High and Low, even considering just spots with % of detection frequency bigger than 75%. The taurine bulls demonstrated more homogeneous profile when comparing with zebu bulls, considering number and frequency of appearance of spots. The results showed that proteomics can be a useful tool to predict the semen freezability, but we ́ll need to study better the interactions between sperm membrane, seminal plasma and extender to comprehend better which proteome phenotype interfere positive or negatively in the semen freezability.

Brasiliporella, a new mid-Cretaceous dasycladacean genus: The earliest record of the Tribe Batophoreae

New material collected in Albian and Cenomanian strata from Brazil helps us to better understand the structure of a poorly known dasycladacean alga, Holosporella nkossaensis P. Masse, in Bull Centr Rech Explor-Prod elf aquitaine, 19: 301-317, 1995: each of its fertile laterals, which are regularly arranged in verticils along the cylindrical algal thallus, consists of a distally inXated primary bearing two vesicular ampullae in terminal position. These traits are not known in representatives of the genus Holosporella Pia, 1930 nor in any genera described to date. On this basis, we introduce the new genus Brasiliporella with Brasiliporella nkossaensis emend. nov. comb. as its typespecies. We also discuss the systematic aYnity of the new taxon: it is ascribed to the Tribe Batophoreae, and in a broader manner the current paleontological 'interpretation of the concept' (in French: 'acception') of the Order Dasycladales, with the creation of two new families and accordingly with the emendation of two other families. © Springer-Verlag Berlin Heidelberg 2012.
