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.

Control of microorganisms of oral health interest with Arctium lappa L. (burdock) extract non-cytotoxic to cell culture of macrophages (RAW 264.7)

Objectives: To evaluate the antimicrobial activity of Arctium lappa L. extract on Staphylococcus aureus, S. epidermidis, Streptococcus mutans, Candida albicans, C. tropicalis and C. glabrata. In addition, the cytotoxicity of this extract was analyzed on macrophages (RAW 264.7).Design: By broth microdilution method, different concentrations of the extract (250-0.4 mg/mL) were used in order to determine the minimum microbicidal concentration (MMC) in planktonic cultures and the most effective concentration was used on biofilms on discs made of acrylic resin. The cytotoxicity A. lappa L. extract MMC was evaluated on RAW 264.7 by MTT assay and the quantification of IL-1 beta and TNF-alpha by ELISA.Results: The most effective concentration was 250 mg/mL and also promoted significant reduction (log(10)) in the biofilms of S. aureus (0.438 +/- 0.269), S. epiderrnidis (0.377 +/- 0.298), S. mutans (0.244 +/- 0.161) and C. albicans (0.746 +/- 0.209). Cell viability was similar to 100%. The production of IL-beta was similar to the control group (p > 0.05) and there was inhibition of TNF-alpha (p < 0.01).Conclusions: A. lappa L. extract was microbicidal for all the evaluated strains in planktonic cultures, microbiostatic for biofilms and not cytotoxic to the macrophages.

Interleukin 10 and tumor necrosis factor-alpha in pregnancy: aspects of interest in clinical obstetrics

The purpose of this study was to review the literature regarding the action of the cytokines interleukin 10 (IL-10) and tumor necrosis factor-alpha (TNF-α) in pregnancy and to emphasize the factors that are of interest to clinical obstetrics. The literature highlights several actions of IL-10 and TNF-α during pregnancy. The actions of these cytokines seem to be antagonistic and dependent on the balance between them, which is orchestrated by the specific immunosuppressive action of IL-10. TNF-α has a characteristic inflammatory action, and it is an additional diabetogenic factor in pregnancy. The loss of the control of the production of these cytokines, with increase of TNF-α, is related to the risk for developing obstetric complications, particularly recurrent fetal loss, gestational diabetes mellitus, hypertensive syndromes, and fetal growth restriction. However, study results are controversial and are not clearly defined. These issues are attributed to the heterogeneity of the studies, particularly regarding their sample sizes and sources, the evaluation methods, and the multiplicity of factors and conditions that influence cytokine production. These questions are fundamental and should be addressed in future investigations to obtain more consistent results that can be applied to obstetric practice.

Generating Interest in Mathematics Using Discussion in the Middle School Classroom

In this action research study of my classroom of 8th grade algebra, I investigated students’ discussion of mathematics and how it relates to interest in the subject. Discussion is a powerful tool in the classroom. By relying too heavily on drill and practice, a teacher may lose any individual student insight into the learning process. However, in order for the discussion to be effective, students must be provided with structure and purpose. It is unrealistic to expect middle school age students to provide their own structure and purpose; a packet was constructed that would allow the students to both show their thoughts and work as a small group toward a common goal. The students showed more interest in the subject in question as they related to the algebra topics being studied. The students appreciated the packets as a way to facilitate discussion rather than as a vehicle for practicing concepts. Students still had a need for practice problems as part of their homework. As a result of this research, it is clear that discussion packets are very useful as a part of daily instruction. While there are modifications that must be made to the original packets to more clearly express the expectations in question, discussion packets will continue to be an effective tool in the classroom.

Improvement of Older Women's Sexuality Through Emancipatory Education

The purpose of this action research (AR) was to explore the ways in which sexuality is experienced daily and to improve the expression of older women's sexuality. The pedagogy of autonomy as proposed by the Brazilian educator Paulo Freire theoretically supported this AR, with the participation of six older adult women living in a rural setting in southwest Brazil. The older women's experiences regarding sexuality, their concerns, and their educational demands could be summarized through five phrases: the improvement of self-esteem as a way to promote sexuality; sexuality impaired by loneliness and lack of affection; men's sexual satisfaction seen as a woman's obligation; women's sexuality controlled by the society; and relinquishment of the companion to attend to the expectations of family members. Dialogical and participative educational approaches and continuous observation-participation strategies were performed to support the women's care and educational requirements.
