Immunophenotyping of thymic lymphoma in a Nelore cow

Thymic lymphoma is a malignant lymphoid neoplasm that affects several species, including cattle. This type of neoplasia can lead to death due to malignant cell infiltration in different organs. The classification of this neoplasm may predict prognosis and response to treatment. Immunophenotyping is one of the ways to perform this classification. There are reports about the performance of immunohistochemistry (IHC) to classify thymic lymphoma only in taurine cattle, therefore the aim of this report is to describe the immunophenotype of a thymic lymphoma in a Nelore cow. Immunostaining was performed with monoclonal antibodies (CD79, CD4 and CD8). The tumor cells showed positive staining only for CD8 T lymphocytes, coinciding with the disease progression, since the T lymphoma type is more aggressive.

Evaluation of the floral vasculature of the Janusia, Mascagnia and Tetrapterys species as a tool to explain the decrease of floral organs in Malpighiaceae

The family Malpighiaceae is considered monophyletic, but the intra-family classification is conflicting. Analyses of floral vasculature allow the identification of reductions, connations and adnations and can even reveal evolutionary steps prior to current floral morphology. The present work analysed the floral vasculature of Janusia mediterranea, Mascagnia cordifolia and Tetrapterys chamaecerasifolia using material processed by traditional methods for light microscopy. A general pattern was observed of three bundle traces supplying each sepal and one trace per petal and stamen; Mascagnia is an exception, as its eglandular sepal has only a median trace but shares lateral traces with adjacent sepals. No dorsal traces are emitted to the carpels; however, three intercarpellary complexes are emitted that divide into six ventral bundles, supplying the ovule. Mascagnia demonstrates connation between the anterior and adjacent sepal glands; reductions of the anterior sepal glands were registered in Tetrapterys and Janusia. This work reveals two distinct processes for gland loss in non-related groups of the family that resulted in similar present appearances. Our evaluation of the number of calyx glands and the processes of glandular loss in species with less than ten glands improves our understanding of the evolution of calyx glands in Malpighiaceae. © 2013 Elsevier GmbH.

Summary of resolutions recently adopted by CDCC and resolutions of ECLAC and other organs of the United Nations which might be of special interest to member countries of ECLAC/CDCC

This paper brings to the attention of member countries of the Caribbean Development and Cooperation Committee (CDCC) resolutions adopted by past sessions of the Committee, since 2000, and the process of their implementation. Resolutions 55 to 66 for the period 2000- 2006 have been extracted from the reports of the eighteenth to twenty first sessions of the CDCC Also included for the information of member countries are selected resolutions recently adopted by the Economic Commission for Latin America and the Caribbean (ECLAC) and other organs of the United Nations. These resolutions greatly influence the preparation of the programme of work and are expected guide the day-to-day functioning of the secretariat. It is a great source of information for delegations, given the perceived special relevance of the resolutions to the membership of the CDCC. The resolutions listed in this document are pertinent to all subprogrammes of ECLAC and indeed the CDCC subprogramme 12 of ECLAC. However, the content of these resolutions either marked no real advance on the outcomes of the corresponding conferences that were held within recent times or were cast in a globally relevant context that did not address specific concerns of Caribbean countries to any significant extent.
