De la baja de un buque de la Armada como recurso socio-económico y ambiental: estrategias para la cohesión y formación del tejido social, el futuro pesquero y la protección ambiental

En la actualidad, la Armada española cuenta con un total de 103 buques (LOBA, 2009). Cada uno de ellos tiene una misión específica de acuerdo a sus características. Dicha misión condicionará la vida útil del navío. Cuando un buque es dado de baja, surgen las siguientes preguntas: ¿Qué hacer con ellos? ¿Tienen alguna utilidad? ¿Generan un impacto ambiental? En este proyecto, se presentan diferentes propuestas que tienen como finalidad obtener el mayor beneficio del recurso. Cada una de ellas buscará el máximo rédito en aspectos como la cohesión en el tejido social y la socio-economía de una zona determinada y la protección del medio marino junto al futuro de la pesca de arrastre en nuestro país. A lo largo del trabajo, se verá la dificultad de desguazar buques con gran eslora en nuestros astilleros, así como también los problemas administrativos y políticos a los que se enfrentan asociaciones y ayuntamientos que quieren adquirir un buque, para convertirlo en un museo o en un pecio, respectivamente. El objetivo principal es dar a conocer cuál es la situación, pero sin entrar a determinar qué opción sería mejor para cada tipo de navío.

Resolution of an Infection with Leishmania braziliensis Confers Complete Protection to a Subsequent Challenge with Leishmania major in BALB/c Mice

Both Leishmania major and L. braziliensis induce cutaneous leishmaniasis in BALB/c mice. Whereas BALB/c mice die of infection with L. major, they cure an infection with L. braziliensis. We report here that after curing an infection with L. braziliensis, BALB/c mice are resistant to challenge with L. major. When challenged with L. major, L. braziliensis pre-treated BALB/c mice mounted a delayed-type hypersensitivity response to L. major and produced high amounts of interferon-g (IFN-g ) but low amounts of interleukin-4. The IFN-g produced by the L. braziliensis pre-infected mice was involved in the protection seen against L. major challenge since treating the mice with a neutralizing anti-IFN-g abrogated the protection. This suggests that cross-reactive antigen epitopes exist between L. braziliensis and L. major and that pre-infection with L. braziliensis primes BALB/c mice to epitopes on L. major that can elicit a protective Th1 response to the parasite.

Partial Protection of Mice against Trypanosoma cruzi after Immunizing with the TcY 72 Antigenic Preparation

A 72 kDa Trypanosoma cruzi glycoprotein recognized by the 164C11 monoclonal antibody (IgM isotype) was purified by preparative electrophoresis. The antigenic preparation obtained, named TcY 72, was used to immunize C57Bl/10 mice. The following results were observed after immunization: (1) induction of higher titres of IgG than IgM antibodies, as evaluated by indirect immunofluorescence; (2) significant DTH after injection of epimastigotes in mice footpads; (3) peak parasitemia in immunized mice was significantly reduced and animals were negative by 13 days post-infection, although the mice still succumb to infection; (4) the phenotypic analysis of spleen cell populations showed a decrease in the CD4/CD8 ratio in immunized mice. Taken as a whole, these findings indicate that TcY 72 is immunogenic and potentially important for protective immunity.

Renal protection with calcium antagonists: the role of lercanidipine.

Abstract Background: Clinical research in the field of hypertension is now increasingly focusing on the potential effects of antihypertensive treatments that may go beyond the reduction of blood pressure (BP). In particular, renal protection appears as a desirable goal, especially considering that hypertension is associated with an increased risk of developing kidney damage, which may eventually lead to end-stage renal disease and a higher mortality. Dihydropyridine calcium channel blockers (CCBs) are widely used in the field of hypertension therapy but the different renal effects of the various CCBs have been poorly explored to date. Scope: This review will discuss available evidence on the renal effects of two calcium channel blockers: amlodipine and lercanidipine, on the basis of clinical data. Methods: MEDLINE and EMBASE were searched for inclusion of relevant studies. No limitations in time were considered. Results: Results from preclinical and clinical studies suggest that amlodipine is overall less effective in terms of renal protection when compared with other antihypertensive tested agents. Its beneficial effect in retarding the progression of renal disease is achievable only when combined with a blocker of the renin-angiotensin system. Conversely lercanidipine seems to provide renal protection in a similar way to ACE inhibitors, probably thanks to its mechanism of action which acts directly on the afferent and efferent renal arterioles. Conclusions: Treatment of hypertension with CCBs should take into consideration the special effects of each single agent at different levels; lercanidipine for example may play a useful role in the management not only of hypertension but also in renal protection of hypertensive patients.

Protection against Toxoplasmosis in Mice Immunized with Different Antigens of Toxoplasma gondii Incorporated into Liposomes

Different toxoplasma antigens were entrapped within liposomes and evaluated, in this form, for their ability to protect Swiss mice against toxoplasma infection: soluble tachyzoite antigen (L/TAg), tissue cyst (L/CAg), tachyzoite plus tissue cyst (L/TCAg) or purified antigen of tachyzoite (L/pTAg). The protein used in L/pTAg was purified from tachyzoites using a stage-specific monoclonal antibody which reacted at a molecular weight of 32 kD in SDS PAGE and silver stain using reduced condition. To compare the immuno-adjuvant action of liposomes and of Freund's Complete Adjuvant (FCA), another group of mice was immunized with soluble tachyzoite antigen (STAg) emulsified in FCA (FCA/TAg). Control groups were inoculated with (STAg) alone, phosphate-buffered saline (PBS), FCA with PBS (FCA/PBS) and empty liposomes (L/PBS). Mice were inoculated subcutaneously with these antigens six, four and two weeks before a challenge with 80 tissue cysts of the P strain of Toxoplasma gondii orally. All mice immunized with or without adjuvant showed a humoral response, as measured by Elisa. However, no correlation was found between antibody titer and protection against the challenge. All mice immunized with L/pTAg or L/TCAg survived (100), whereas 80% and 90% of mice from groups which received respectively PBS or FCA/PBS and L/PBS died. All mice immunized with antigens entrapped within liposomes (L/TAg, L/CAg, L/TCAg and L/pTAg) showed low numbers of intracerebral cysts.

Pilot HIA of European Employment Strategy in Ireland

This pilot Health Impact Assessment (HIA) exercise was conducted as part of the ‘Policy Health Impact Assessment for the European Union’, commissioned by the European Commission ’s Directorate Generale Health and Consumer Protection (DG Sanco). The project is coordinated by Liverpool University and the research partners are from Ireland, Germany and the Netherlands. The aim of the European project is to develop a HIA methodology for assessing the health impacts of EU policies and activities. The purpose of the pilot HIA in Ireland was to test the methodology produced in the first phase of the project in 2002. The policy chosen for assessment was the European Employment Strategy. The Irish pilot used a range of methods suggested in the draft methodology but concentrated particularly on the participatory aspects of HIA. A key stakeholder group with knowledge of employment (including decision makers in labour market policy) was established to provide expert advice and support. Other methods used included policy analysis, information gathering from key informants, community profiling (including demographic and labour force data), data analysis, literature review, the production of a report and the development of recommendations.

IPH response to the Environmental Protection Agency Consultation on Stategic Environmental Assessment (SEA) Process Checklist

The Institute of Public Health in Ireland is an all-island body which aims to improve health in Ireland by working to combat health inequalities and influence public policies in favour of health. The Institute promotes co-operation in research, training, information and policy in order to contribute to policies which tackle inequalities in health. Over the past six years the Institute has worked closely with the Department of Health and Children and the Department of Health, Social Services and Public Safety in Northern Ireland to build capacity for Health Impact Assessment. The Institute takes the view that health is determined by policies, plans and programmes in many sectors outside the health sector as well as being dependent on access to and availability of first class health services. The importance of other sectors is encapsulated in a social determinants of health perspective which recognises that health is largely shaped and influenced by the physical, social, economic and cultural environments in which people live, work and play. Figure 1 illustrates these multi-dimensional impacts on health and also serves to highlight the clear and inextricable links between health and sustainable development. Factors that impact on long-term sustainability will thus also impact on health.

Is there a role for autoimmunity in immune protection against malaria?

Much remains to be known about the mechanisms involved in protective immunity against malaria and the way it is acquired. This is probably the reason why, in spite of so much progress, it has not yet been possible to develop an anti-malaria vaccine able to induce parasite specific antibodies (Ab) and/or T-cells. It has been considered in the early 80s that the induction of efficient protection against the blood stage forms of Plasmodium falciparum would not be possible without simultaneously eliciting an autoimmune (AI) response against erythrocytes, even at the price of inducing an AI pathology. Despite the description of the reciprocal relationship, i.e. the protective effect of malaria on the development of AI diseases - demonstrated since 1970 - no effort has been made to verify the possible involvement of the AI response in protection against malaria. With this end in view - and in the light of the knowledge acquired in autoimmunity and the existence of the so called "natural" (not associated with pathology) autoantibodies - we propose to examine the hypothesis that the participation of the AI response (not necessarily restricted to autologous erythrocyte antigens) in the immune protection against malaria is possible or even necessary.

Sexually transmitted diseases in homosexual and bisexual males from a cohort of human immunodeficiency virus negative volunteers (Project Horizonte), Belo Horizonte, Brazil

Sexually transmitted diseases (STD) are very frequent in the whole world. Males who do not use a condom during their sexual relations are at great risk. We report cases of STD during six months of observation, among homosexual/bisexual males who participate in the Project Horizonte. There were 16 cases of genital warts, 6 cases of human immunodeficiency virus infection, 24 cases of unspecific urethritis, 28 cases of herpes simplex virus infection, 30 cases of syphilis, 58 cases of gonorrhea and 84 cases of pediculosis. We concluded that a condom must be used in all sexual relations and new counseling techniques are needed, to avoid this situation.

Vertical toxoplasmosis in a murine model. Protection after immunization with antigens of Toxoplasma gondii incorporated into liposomes

Distinct Toxoplasma gondii antigens were entrapped within liposomes and evaluated for their ability to protect Balb/c mice against congenital transmission: soluble tachyzoite antigen (L/STAg), soluble tissue cyst antigen (L/SCAg), soluble tachyzoite plus tissue cyst (L/STCAg) or purified 32kDa antigen of tachyzoite (L/pTAg). Soluble tachyzoite antigen alone in PBS (STAg) or emulsified in Freund's Complete Adjuvant (FCA/STAg) was also evaluated. Dams were inoculated subcutaneously with these antigens 6, 4 and 2 weeks prior to a challenge with four tissue cysts of the P strain of T. gondii orally between 10 and 14 days of pregnancy. Significant diminution differences were observed between the frequency of infected pups born of the dams immunized with the antigens incorporated into liposomes and that of pups born of the dams immunized with antigen emulsified in FCA or non immunized group (p<0.05). There was a significant decrease in the number of pups born dead in the groups L/STAg, L/SCAg and L/pTAg when compared with pups from all other groups (p <0.05). All dams immunized with or without adjuvant showed an antibody response and a proliferation of T-cells. However, no correlation was found between immune response and protection against the challenge.
