37. Fusión totalitaria y separación utópica: lectura de Emmanuel Lévinas y Miguel Abensour
This articule attemps to clarify the unique social structure, which defines utopia in Levinas's thought, emphasizing its structural antagonism to the social form of the totalitarian structure. We argue that Levinasian utopia, as social form, is founded on the matrix of the "intersubjective separation". Hence, under this relation, the Levianasian utopia appea

38. The place of normativity in the political ontology of Ernesto Laclau
This article is a reflection on normativity in the field of political theory, with the ontological dimension found in Ernesto Laclau's discourse theory as a presupposition. We base ourselves on the premise that, as a political theorist (rather than a political philosopher), Laclau has developed a political theory with great analytical applicability, which is

39. Antifungal compounds as a mechanism to control Hemileia vastatrix by antagonistic bacteria
Pseudomonas putida P286 and Bacillus thuringiensis B157 controlled coffee rust under greenhouse and field conditions. Now we studied the mechanism(s) of antagonism of both bacteria to Hemileia vastatrix. Bacterial effects on urediniospore germination and disease severity were evaluated in experiments with six treatments: (i) growth broth, (ii) supernatant ce

40. Antagonistic activity expressed by Shigella sonnei: identification of a putative new bacteriocin
Bacteriocins are antibacterial, proteinaceous substances that mediate microbial dynamics. Bacteriocin production is a highly disseminated property among all major lineages of bacteria, including Shigella. In this paper, we addressed the purification and characterisation of a bacteriocin produced by a Shigella sonnei strain (SS9) isolated from a child with ac

41. Increased enzymatic activity in rice leaf blast suppression by crude extract of Epicoccum sp
Epicoccum sp. showed in vitro antagonism to the rice pathogens Magnaporthe oryzae, Rhizoctonia solani, Sarocladium oryzae, Monographella albescens and Cochliobolus miyabeanus in dual culture. The colony growth of the rice blast fungus, M. oryzae, was reduced by 42.50%. The lethal doses (LD50) determined based on probit-log dosage response curves at 3 and 6 h

42. Role of killer factors in the inhibitory activity of bio-control yeasts against Penicillium expansum and Aspergillus ochraceus
This work evaluated the antagonism of killer positive yeast strains (isolated from 11 samples of different frozen fruit pulps) against the strains of Penicillium expansum and Aspergillus ochraceus. Of the total 41 killer yeasts tested in YM agar, 19 showed antibiosis against P. expansum and A. ochraceus, with inhibition zone ranging from 10 to 18 mm and 10 t

43. La confrontación de la sexualidad en la práctica profesional de los futuros médicos: la mirada de los pasantes de medicina
The subject of sexuality in academic and service institutions is perceived through predominantly biological conceptual perspectives, blurring the subjective component that is imbued in social and cultural processes. The meanings that medical staff construct around sexuality have implications in their professional development and practice. This work presents

44. Estrogen and progesterone receptors in endometrial polyps of women exposed and not exposed to tamoxifen and in atrophic endometrium / Receptores de estrógeno e progesterona em pólipos endometriais de usuárias e não usuárias de tamoxifeno e no endométrio atrófico
Introduction: Tamoxifen has been used for the treatment of strogen receptor-positive breast cancer. The effect of tamoxifen in breast cancer is the it inhibition cancer cell growth by competitive antagonism with strogen for strogen receptor (ER). The mechanism of action of tamoxifen in this receptor varies among different tissues, with antagonist effect (e.g

45. Bactericidal antibiotic-phytochemical combinations against methicillin resistant Staphylococcus aureus
Methicillin resistant Staphylococcus aureus (MRSA) infection is a global concern nowadays. Due to its multi-drug resistant nature, treatment with conventional antibiotics does not assure desired clinical outcomes. Therefore, there is a need to find new compounds and/or alternative methods to get arsenal against the pathogen. Combination therapies using conve

46. Production of lytic enzymes by Trichoderma isolates during in vitro antagonism with Aspergillus niger, the causal agent of collar rot of peanut
Twelve isolates of Trichoderma (six of T. harzianum, five of T. viride, one of T. virens), which reduced variably the incidence of collar rot disease caused in peanut by Aspergillus niger Van Tieghem, were evaluated for their potential to produce lytic enzymes during in vitro antagonism. T. viride 60 inhibited highest (86.2%) growth of test fungus followed b

47. Biological control of rice brown spot with native isolates of three Trichoderma species
Brown spot caused by Bipolaris oryzae is an important rice disease in Southern coast of Caspian Sea, the major rice growing region in Iran. A total of 45 Trichoderma isolates were obtained from rice paddy fields in Golestan and Mazandaran provinces which belonged to Trichoderma harzianum, T. virens and T. atroviride species. Initially, they were screened aga

48. Análisis químico del extracto peciolar para evaluar el estado nutricional en la vid
The objective of this work was to evaluate the relationship between N, P and K concentration in petiole extract, blades and roots, to determine the nutritional status in grapevine. The experiment was done between December 2006 and February 2007. Three fertilization trials with N, P2O5 and K2O in one-year-old Vitis vinifera 'Red Globe' plants, grown in contai
