Abstract: Se efectuó la validación de la coloración de Papanicolaou, utilizada para citología vaginal, frente a la coloración fluorescente con naranja de acridina, a fin de evaluar el valor de un resultado negativo para Trichomonas vaginalis obtenido en un PAP. Se estudiaron 80 muestras de flujo vaginal de mujeres entre 18 y 45 a os, pacientes de consultorios externos de Ginecología del Hospital Municipal de la ciudad de Bahía Blanca, Provincia de Buenos Aires (Argentina). Las muestras se colorearon paralelamente por la técnica de Papanicolaou y por la coloración fluorescente con naranja de acridina. Los resultados mostraron que el PAP presenta una sensibilidad del 54,5% para la detección de T. vaginalis, validación efectuada frente a la coloración fluorescente con naranja de acridina, para una prevalencia de enfermedad en el grupo de mujeres estudiadas del 13,75% y un nivel de confianza del 95%. Para ensayos "en paralelo" con ambas coloraciones, el valor global de la prueba fue del 93,8%, con un valor predictivo del resultado negativo del 93,2%. Concluimos que si bien T. vaginalis es detectada en el PAP, éste no presenta sensibilidad significativamente elevada como para ser considerada como única prueba, debiéndose complementar siempre con una coloración fluorescente con naranja de acridina, u otra prueba de similar valor The present study examined the validity of PAP staining, as used for vaginal cytology, against fluorescent staining with acridine orange in order to determine the value of a negative result of Trichomonas vaginalis obtained by a PAP smear. We examined eighty vaginal-secretion samples from 18- to 45-year-old female patients of the Hospital Municipal of the city of Bahía Blanca, Province of Buenos Aires, Argentina. The samples were stained in parallel by the PAP smear technique and the fluorescent staining technique with acridine orange described by Fripp in 1975. The results of our validation tests demonstrated that, against fluorescent staining with acridine orange, the PAP smear has a 54.5% sensitivity for the detection of T. vaginalis for a 13.75% prevalence of disease among the females in the study with a 95% confidence level. In assays conducted "in parallel" for both stainings, the global value of the test was 93.8%, with a predictive negative value of 93.2%. We conclude that, although the PAP smear can detect T. vaginalis, its sensitivity is not high enough for the test to be used as the sole diagnostic means and the test must always be supplemented with fluorescent staining with acridine orange or another test of similar value.

European Journal of Psychology Applied to Legal Context , 2009,
Abstract: A sample of 46 men was evaluated with the DAPP (Questionnaire of Domestic Aggressor Psychological Profile). All were inmates convicted for various degrees of violence against their wives in different prisons. The sample was divided into three groups: homicides without previous violence against their wives (H) (n=11), homicides with previous violence (VH) (n=9) and domestic batterers without previous homicide attempts against their partners (B) (n=26). The aim of the study was to analyze the possible existence of three different kinds of profiles and more specifically if it’s possible to obtain an independent profile for domestic homicides with previous episodes of violence against their wives. The results neither confirm the hypothesis as whole nor for the violent homicides. However, differences between groups were obtained in the admission and description of the facts, in the risk of future violence, in some sociodemographical characteristics (i.e., level of education, social status), in the couple relationship, in the dissatisfaction concerning the unachieved ideal woman, in the use of extreme physical force during the aggression, the time of the first aggression, the use of verbal threats during the aggression, explanation of the events to the family and the period of time between the beginning of the romantic relationship and the manifestation of violence. The implications of the results for the theoretical frameworks proposed and future research are discussed.
Recent Developments in the Theory of Lorentz Spaces and Weighted Inequalities
Maria J. Carro,Jose A. Raposo,Javier Soria
Mathematics , 2000,
Abstract: The main objective of this work is to bring together two well known and, a priori, unrelated theories dealing with weighted inequalities for the Hardy-Littlewood maximal operator $M$, and thus, we consider the boundedness of $M$ in the weighted Lorentz space $\Lambda^p_u(w)$. Two examples are historically relevant as a motivation: If $w=1$, this corresponds to the study of the boundedness $M:L^p(u)\longrightarrow L^p(u),$ which was characterized by B. Muckenhoupt, giving rise to the so called $A_p$ weights. The second case is when we take $u=1$. This is a more recent theory, and was completely solved by M.A. Ari\~no and B. Muckenhoupt in 1991. It turns out that the boundedness $M:\llo\longrightarrow\llo,$ can be seen to be equivalent to the boundedness of the Hardy operator $A$ restricted to decreasing functions of $L^p(w)$. The class of weights satisfying this boundedness is known as $B_p$. Even though the $A_p$ and $B_p$ classes enjoy some similar features, they come from very different theories, and so are the techniques used on each case: Calder\'on--Zygmund decompositions and covering lemmas for $A_p$, rearrangement invariant properties and positive integral operators for $B_p$. It is our aim to give a unified version of these two theories. Contrary to what one could expect, the solution is not given in terms of the limiting cases above considered (i.e., $u=1$ and $w=1$), but in a rather more complicated condition, which reflects the difficulty of estimating the distribution function of the Hardy-Littlewood maximal operator with respect to general measures.

Acta Odontológica Venezolana , 2006,
Abstract: El Liquen Plano Bucal (LPB) es una enfermedad mucocutánea, de carácter inflamatorio, y de curso crónico. La Organización Mundial de la Salud incluyó al LPB como un estado precanceroso definiendo como tal, a un proceso generalizado que se asocia con un riesgo significativamente mayor de presentar cáncer. Numerosos estudios han documentado el potencial premaligno del LPB. Sin embargo, la asociación del LPB a lesiones malignas es hasta el momento un tema controvertido. El objetivo de este trabajo es comunicar un caso de LPB, Carcinoma de Células Escamosas (CCE) y Carcinoma Verrugoso de Ackerman (CVA) en un paciente de 59 a os de edad quien no refirió tener hábitos de uso de tabaco o consumo de alcohol. Los tres tipos de lesiones fueron diagnosticadas simultáneamente , en la misma localización anatómica. El reporte de este nuevo caso clínico sugeriría la necesidad de realizar exámenes de seguimiento regulares a los pacientes con LPB, en especial a quienes presentan formas atróficas-erosivas y/o factores de riesgo. Oral lichen planus, or OLP, is a chronic inflammatory mucocutaneous disease. Precancerous conditions are defined as a generalized state associated with a significantly increased risk of cancer. The World Health Organization defined lichen planus as precancerous conditions. Several studies have addressed the issue of the premalignant potential of lichen planus. Some aspects of this pathology are still controversial. The aim of this article is to document the development of squamous cell carcinoma (SCC) and Ackerman verrucous carcinoma Ackerman (AVC) in a 59 year old man with an oral lesion diagnosed clinically as OLP. He was non smoker and no alcohol habits. At the time of diagnostic the three lesions simultaneously were found in the same anatomic place. This new case of malignization suggests the needs to carry out examinations particularly important in patients who have atypical form of OLP and /or risk factors.
Aquaporins: Their role in cholestatic liver disease
Guillermo L Lehmann, Maria C Larocca, Leandro R Soria, Raúl A Marinelli
World Journal of Gastroenterology , 2008,
Abstract: This review focuses on current knowledge on hepatocyte aquaporins (AQPs) and their significance in bile formation and cholestasis. Canalicular bile secretion results from a combined interaction of several solute transporters and AQP water channels that facilitate water flow in response to the osmotic gradients created. During choleresis, hepatocytes rapidly increase their canalicular membrane water permeability by modulating the abundance of AQP8. The question was raised as to whether the opposite process, i.e. a decreased canalicular AQP8 expression would contribute to the development of cholestasis. Studies in several experimental models of cholestasis, such as extrahepatic obstructive cholestasis, estrogen-induced cholestasis, and sepsis-induced cholestasis demonstrated that the protein expression of hepatocyte AQP8 was impaired. In addition, biophysical studies in canalicular plasma membranes revealed decreased water permeability associated with AQP8 protein downregulation. The combined alteration in hepatocyte solute transporters and AQP8 would hamper the efficient coupling of osmotic gradients and canalicular water flow. Thus cholestasis may result from a mutual occurrence of impaired solute transport and decreased water permeability.
The Olfactory Transcriptomes of Mice

PLOS Genetics , 2014, DOI: doi/10.1371/journal.pgen.1004593
Abstract: The olfactory (OR) and vomeronasal receptor (VR) repertoires are collectively encoded by 1700 genes and pseudogenes in the mouse genome. Most OR and VR genes were identified by comparative genomic techniques and therefore, in many of those cases, only their protein coding sequences are defined. Some also lack experimental support, due in part to the similarity between them and their monogenic, cell-specific expression in olfactory tissues. Here we use deep RNA sequencing, expression microarray and quantitative RT-PCR in both the vomeronasal organ and whole olfactory mucosa to quantify their full transcriptomes in multiple male and female mice. We find evidence of expression for all VR, and almost all OR genes that are annotated as functional in the reference genome, and use the data to generate over 1100 new, multi-exonic, significantly extended receptor gene annotations. We find that OR and VR genes are neither equally nor randomly expressed, but have reproducible distributions of abundance in both tissues. The olfactory transcriptomes are only minimally different between males and females, suggesting altered gene expression at the periphery is unlikely to underpin the striking sexual dimorphism in olfactory-mediated behavior. Finally, we present evidence that hundreds of novel, putatively protein-coding genes are expressed in these highly specialized olfactory tissues, and carry out a proof-of-principle validation. Taken together, these data provide a comprehensive, quantitative catalog of the genes that mediate olfactory perception and pheromone-evoked behavior at the periphery.
Grete Stern: imágenes del goce femenino
Soria,Claudia;
Mora (Buenos Aires) , 2010,
Abstract: informed by the theory of jouissance that freud, lacan and cixous elaborate, this paper explores the photographic series entitled "dreams" that grete stern publishes in buenos aires in idilio (1948-51). in a magazine aimed for a feminine audience of middle and low class, the series of this german graphic designer and photographer who arrives in buenos aires in 1935, illustrates the section called "psychoanalysis will help you." the section publishes the dreams that readers submit to the magazine so that richard rest (nickname for gino germani and enrique butelman) would give his interpretation. its is precisely following the path of the dreams as represented by grete stern that one can observe a solidarity between women's agency and the beginning of psychoanalytic practice in the culture of buenos aires.
A MINIMALIST APPROACH TO MULTI-LEVEL IT-HUMAN INTEGRATION IN TRANSLATION WORK'
Jesus Soria
International Journal of English Studies (IJES) , 2002, DOI: 10.6018/ijes.2.1.48601
Abstract: This article attenlpts to define the intimate relationship that is intended between c1assroon1-based and laboratory-based activities, between private study and language class, between individual and collective effort and between computer-centered and teacher-led learning. We tend to take it as an axiom o€ CALL that the place of IT is beside the teacher, its function complementary or suplementary. Typically. the teacher's role is usually one (occasionally just a couple) of these: designer, author, editor, tester, provider, trainer, checker or supervisor. Except when in a supervisory role, the teacher's role is taken over by the computer when the teacher's own activity stops. This is what we tend to call computer-aided instruction. In the vast majority of cases, the role of IT is extrinsic to the teacher's own activity. I shall try to demonstrate here that the aid that the coMputer is able to provide can be effectively brought right into the classroom as an integral, intrinsic part of the teacher's own activity and that, by doing so, it can enhance not only the teacher's activity but also the complementary role which is traditionally assigned to the computer. The processes described here were developed with a specific situation in mind, not atypical in, at least, British Higher Education: increased mixed ability and reduced teaching time. In a pedagogical context that, in spite of mission statement protestations, usually attempts to make the most of the average, they specifically target the lower and higher ability student ranges. New funding has been secured to continue with this research from September 2002.
Estrategias para combatir el terrorismo desde la Comunicación Política y la Comunicación Informativa
Carlos Soria
Palabra Clave , 2001,
Abstract: El terrorismo no puede ser comprendido ni combatido únicamente en términos de fuerza, sino también en términos de comunicación política e informativa. Los terroristas necesitan a los medios de comunicación y por ello estos últimos deben pensar cuál es la estrategia y la posición que deben asumir frente al cubrimiento de conflictos. En una propuesta de cinco puntos se condensan los principales aspectos para intentar palear los efectos perseguidos por los terroristas o hacerlos imposibles.
