The results of three different prostaglandin treatment protocols are summarized in our summary: In the first experiment the effects of different doses (0 mg, 25 mg vs 35 mg) of prostaglandin treatments from the day of treatment (Day 0) were examined. The percentage changes relative to the corpus luteum area decreased, and the percentage changes relative to the largest follicle area increased faster, and even the oestrus started sonner in cocas treated with 35 mg PGF2a than in those treated with 25 mg PGF2a. However, these differences between groups were not statistically significant. At the same lime, the decrease in the percentage changes relative to the area of corpora lutea and to the concentrations of P4 was statistically significant in both groups. In the second experiment treatment of dairy cows with 2 luteolytic dosages of PGF2a or its synthetic analogue at an 8-h interval resulted in more cows (non-significantly) (18 vs. 21) being observed in oestrus within 5 d after treatment and having significantly higher conception rate (27,8% vs. 66,6%) than with 1 treatment. Further studies in progress should confirm the benefit of 2 prostaglandin treatments in a larger scale. At the same lime, the type and the number of prostaglandin treatments had no effect on the incidence of ovulations alter oestrus, the number of ovulations without oestrous signs, the number of cows without oestrus and ovulation, and the average lime from treatment to oestrus. In the third experiment the lime of ovulation was examined alter detected oestrus and A.I. (Day 0) in prostaglandin treated and non-treated dairy cows. Large variations in the area of the CL were detected in the prostaglandin treated and untreated cows. The areas of the largest follicles in treated cows were somewhat smaller during the experiment, than those in untreated cows however those differences between the groups and within the groups were not statistically significant. The area of the largest follicle in cows with no ovulation also did not differ significantly. Some of the cows (n=7) in treated and non-treated groups did not ovulate at all during the experiment. The mean area of the ovulatory follicle on the day before ovulation was somewhat greater but not significantly, if ovulation occurred later regarding to AI, The overall conception rate was > 50% in both groups, but when the cows ovulated too early or too late in relation to the lime of AI the conception rate was significantly louver, therefore determination of the optimal lime for AI is of great practical importance. If ovulation does not occur within two days alter AI second AI may be recommended. Further studies are needed to evaluate the benefit of the second AI [less ▲]

Matrix metalloproteases represent a family of proteases secreted as latent inactive enzymes able to degrade the majority of extracellular matrix components. These enzymes are overexpressed during several pathological tissue remodelings including tumor progression and tumor invasion. It was indeed classically admitted that matrix metalloproteases involved in tumoral progression were preferentially expressed by cancerous cells. Our studies on gelatinase A and stromelysin-3 have, however, demonstrated that their messenger RNAS are detected in fibroblasts of the peritumoral stroma in human mammary carcinoma and not in the cancerous cells themselves. By immunohistochemistry, we have detected gelatinase A in the cytoplasm of fibroblasts and at the surface of the tumor cells. This membrane localization of the protein could result from its binding, following secretion by the neighbouring stromal cells, to a specific binding site expressed at the surface of the carcinoma cells. These cells are indeed able to induce an increased proteolytic activity by enhancing the transcription of these enzymes by peritumoral fibroblasts. These enzymes represent therefore potential targets for the development of new therapeutic strategies. [less ▲]

The role of the extracellular matrix (ECM) in the tumor microenvironment is not limited to being a barrier against tumor invasion. The ECM is a reservoir of cell binding proteins and growth factors that affect tumor cell behavior. It is also substantially modified by proteases produced by tumor cells or stroma cells. As a result of the activity of these proteases, cell-cell and cell-ECM interactions are altered, new biologically active ECM molecules are generated, and the bioavailability and activity of many growth factors, growth factor receptors, and cytokines are modified. ECM-degrading proteases also play a critical role in angiogenesis, where they can act as positive as well as negative regulators of endothelial cell proliferation and vascular morphogenesis. This review article summarizes some of the most relevant findings made over the recent years that were discussed at a workshop organized by the Path B Study Section of the National Institutes of Health in October 2002.

Este trabajo intenta desde una de las múltiples formas posibles abordar el estudio del patrimonio cultural. El primero de sus propósitos es presentar un análisis jurídico sobre el desarrollo evolutivo del concepto, su significado, los bienes y valores que comprende y su funcionalidad como crisol de identidades, dentro del marco normativo de la jurisdicción colombiana y el correspondiente régimen que somete el acervo cultural de la nación. El segundo propósito es plantear el pluralismo como principio fundamental que orienta y describe la acción del Estado Social de Derecho hacia el reconocimiento efectivo de las diversidades que conforman el pueblo colombiano. Se intenta demostrar, que la integración nacional sólo se logra cimentando la identidad cultural sobre el diálogo intercultural y la disposición abierta a la interacción con otras culturas dentro y más allá del ámbito Estatal.

Under non-parametric market conditions, investors usually become more concerned about the return of their money than about the return on their money. Protecting assets becomes the surest if not the only path to survival and growth. High frequency trading systems, over leveraged shadow entities, flash crashes, and stealth central bank actions, to name a few, contribute to create a “Rumsfeldian” type of world in which decision makers have to cope not only with “Known knowns” – things they know that they know – but also with “Unknown unknowns” – things they don’t know that they don’t know! The goal of this paper is to explore such a conceptual model of the “Unknown” and to derive from it a concise and coherent set of battle-tested heuristics aimed at designing effective investment strategies to protect assets.

Many immunological aspects of pregnancy, such as the role played by gamma interferon (IFN-gamma) in abortion, are not well understood. Neospora caninum is an intracellular protozoan considered to be among the main causes of abortion in cattle worldwide. The present study analyzes the interaction between IFN-gamma production and N. caninum infection in naturally infected pregnant cows. Data were obtained from 126 pregnant cows: 86 seropositive and 40 seronegative for the parasite. Pregnancy diagnosis and blood sample collection were performed on days 40, 90, 120, 150, 180 and 210 post-insemination or until the time of abortion detection. Plasma was tested for antibodies against N. caninum and IFN-gamma. Interferon-garmna was detected at some point along the pregnancy in 16 (19%) of the 86 Neospora-seropositive cows yet was undetectable in the 40 seronegative animals. Of the 126 pregnancies examined, 22 (17.5%) ended in abortion. Abortion occurred in 24.4% of seropositive cows (21/86) and in 2.5% of seronegative animals (1/40). Significant (P < 0.0001) interaction was observed between Neospora-seropositivity and IFN-gamma production. Based on the odds ratio, the risk of abortion was 15.6 times higher in seropositive cows not producing IFN-gamma than in seronegative animals, whereas neosporosis had no effect in seropositive cows with IFN-gamma production. A significant (P = 0.001) negative effect of IFN-gamma production on the Neospora titer was furthermore observed in the 65 non-aborting seropositive animals. These results indicate that IFN-gamma production affords protection against abortion in Neospora-infected cows and also point to a reduced humoral immune response to N. caninum during gestation in cows producing IFN-gamma.

All farmers receiving direct payments are subject to compulsory cross-compliance which includes standards related to the maintenance and protection of permanent pastures. Questionnaire techniques and spatio-temporal analyses demonstrated that the ratio of permanent pasture area to agricultural land provides a simple tool for monitoring and controlling the protection of permanent pastures at the regional to Member State level. Huge variations in the ratio across Europe were related to the importance of permanent pastures, the interpretation of definitions, sources of information used, differences in calculation, and the presence of protective and/or sensitive zones. Precautionary or complementary measures are in place in most Member States in order to prevent decreases in the ratio. The implementation of GAEC standards related to permanent pastures overlaps with the standard management requirements, national legislation and current agri-environmental programmes. The study advocates the establishment of a comprehensive geo-information platform consisting of a topologically correct inventory of all permanent pasture parcels in a 1:1 geo-referenced relation between IACS and LPIS; ancillary spatially explicit data such as orthophotos, remote sensing images and other thematic geo-databases; and, geodatabases with parcel information compiled for other monitoring purposes such as those within the framework of the Nitrates Directive or 2nd pillar support.
