In this article, some inkling of normativity linked to the gender division is problematized from a feminist theoretical framework. The qualitative approach crosses History and Greek mythology to recount a contemporary situation through a comparative analysis of two Latin American poems written in the 1990s. The Mexican poetess Nancy Cárdenas and The Peruvian poetess Violeta Barrientos explore and construct a feminine lyrical subject that breaks with the model of femininity and canonic love. The proposal presented contributes to the historiography of lesbian poetry written by women in the twentieth century and offers elements of stylistic analysis. Cárdenas refers to a French woman writer whose literary work was controversial. Barrientos refers to one of the emblematic myths of female monstrosity. Their verses reveal the erotic-affective relation between women and show the difficulties and resolutions to break into a way of life as well as having sexual practices that deviate from the socially accepted. The analysis indicates experience as a process in the formation of subjectivity because they show female subjects that propose and carry out actions instead of being inert or only receptive subjects.

This paper presents a new interpretation of the first movement of Schumann's Fantasie op. 17 that combines formal function and expressive gesture. It offers a brief critique of previous interpretations, and presents a reading based on simultaneous conflicting designs, a number of fluid sections that change functions as they move toward and away from points of stability, and an overall narrative that arises from repeated denials of the kind of fulfillment associated with normative dynamic curves.

The aim of this work was to evaluate a quorum-quenching approach to identify functions regulated by quorum sensing in Enterobacter cloacae. We employed an aiiA transconjugant strain of E. cloacae that synthesizes a lactonase enzyme that hydrolyzes N-acyl homoserine lactone signaling molecules to compare bacterial phenotypes in the presence and absence of quorum signals. The aiiA-expressing strain displayed increased proteolytic activity and intensity of a milk-clotting reaction when compared to the wild-type strain. Although both strains growing on polystyrene plates in rich media and a minimal medium of salts formed biofilms, the wild-type strain exhibited a higher number of adhered cells. On the surface of stainless steel coupons that were submerged in culture media, the number of adhered cells of the wild type contained up to one log more cells compared with the aiiA transconjugant. However, after 48 h of incubation, there was no significant difference between the strains. The results demonstrated that the quorum-sensing system negatively regulates proteolytic activity and is likely involved in the early steps of biofilm formation by E. cloacae 067.

Local Tolerance studies for vaccine products are a main link in the chain of Regulatory Requirements for toxicological preclinical studies. Mainly considering that the use of mucosal road seems to be a current tendency due to the advantages it offers. Sprague Dawley rats of both sexes weighing 100-120 g (reception weight) provided by CENPALAB with the corresponding certificates of sanitary and genetic quality were used in this test. Local tolerance study lasted 17 days. Rats were distributed in 5 groups (3 groups with different cochleate concentrations, one without inoculation and another one that received the diluents of the product in test. Measurement of weight increase, food and water consumption, as well as the anatomopathologic studies in the two times of sacrifice, at 12 and 17 days were performed. Main histopathological studies were carried out in brain and nasal nostrils in three levels of their extension (anterior, medium and posterior areas). In addition, immunological assays such as the determination of IgG in serum, saliva and cerebrospinal fluid (CSF) were carried out. Results showed a sustained weight increase. There were no clinical alterations during water and food consumption, while the existence of discreet acute inflammatory changes was found by anatomopathological studies, which were directly related to the increase of the product concentration. The presence of IgG antibodies in saliva and in sera of the rats inoculated with the cochleates showed significant differences (P <0.05) compared to the non inoculated control group and to the animals inoculated with the diluent. CSF studies resulted negative regarding the presence of specific IgG antibodies. The existence of a direct relation among the concentrations of the product in test and the inflammatory processes in the medium and posterior levels of the nasal nostril was proven, therefore it is considered that cochleates applied by this route and in the concentrations used are innocuous and immunogenic.

The present paper evaluates the toxicity by single dose of the diphtheria-tetanus vaccine (VA-DIFTET®) in Sprague Dawley rats. Its administration was carried out by intramuscular route because this is the one proposed for use in humans. 0.3 mL of the vaccine or its components was administered to a total of 20 animals per group (10 per each sex). These animals were daily observed and, water and food intake was measured on alternate days determining their body weight with week intervals. The anatomopathological analysis of animals was included at the end of the study. No animal died during the assay or clinical symptoms were observed either. No statistically significant differences (p>0,1) were detected regarding water-food intake and body weight. In the anatomopathological study, macrophagic granulomatous lesions were observed in the rats treated with the vaccine or placebo; this finding is characteristic of vaccines adjuvated with aluminum hydroxide. Results suggested that VA-DIFTET® is potentially innocuous when administering the single dose by intramuscular route. [ABSTRACT FROM AUTHOR]
