Interrelationship between reproductive hormones and acute phase proteins during estrous cycle and pregnancy in Spanish purebred broodmares
In some species, female steroid hormones modify the profile of acute phase proteins (APPs) during the estrous
cycle and pregnancy, according to the ovulation, embryonic implantation and placental development; however,
nowadays there’s no experimental evidence for equine species. Objectives of this study were: to compare the
serum amyloid A (SAA), haptoglobin (Hp) and C-reactive protein (CRP) concentrations between cyclic and
pregnant mares, and to analyze the influence of estradiol-17β (E2) during estrous cycle or estrone sulfate (E1)
during pregnancy, and progesterone (P4) on these proteins to assess their potential role to identify the cyclicity or
pregnancy in Spanish mares. Blood samples were taken from 20 Purebred Spanish mares on the day of ovulation
(day 0), on days +5 and +16 post-ovulation, and then, monthly during the whole pregnancy. SAA, Hp and CRP
did not change between day 0, +5 and +16 post-ovulation days. P4 concentrations were significantly higher on
day +16 than on days +5 and 0; and E2 concentrations were significantly higher on day 0 than day +5. On the
other hand, pregnancy was characterized by a progressive increase in the Hp, variable modifications of E1 and P4
concentrations, without changes in SAA and CRP. The absence of significant differences in the APPs between
days 0, +5 and +16, suggested that these proteins cannot be used as biomarkers of diagnosis of heat or pregnancy in Spanish mares, at least early, since the Hp later increases during the gestation. Nevertheless, it is
possible to use them for comparative purposes with other equine breeds, as supervisor instrument of health status
in breeding females as diagnostic tools to monitor pregnancy’s development and/or subclinical reproductive
inflammations, that could lead to the early embryonic death.Veterinari
Statute of the body in times of puberty. Readings from a clinical material
El presente trabajo se desprende de las elaboraciones teórico-clínicas realizadas a partir del Proyecto de Investigación de la Facultad de Psicología de la Universidad Nacional de La Plata “Estatutos del cuerpo en las formas actuales de presentación subjetiva en púberes y adolescentes de la ciudad de La Plata. Indagaciones preliminares”, dirigido por la Lic. Florencia Almagro y codirigido por la Lic. Andrea Elizabeth Mirc.
El análisis que realizaremos se enmarca dentro de la complejidad del campo de la clínica con niños y adolescentes, campo que envuelve en su interior los tiempos de la constitución de la tópica psíquica y, por lo tanto, la dimensión de la sexualidad.
Tal como venimos trabajando en el mencionado proyecto, partimos de pensar problemáticas clínicas que se encuentran en los “límites de lo analizable”, en las cuales la dimensión de lo corporal plantea, para el psicoanálisis, interrogantes que ponen a prueba sus enunciados metapsicológicos, nuevas complejizaciones que abren viejos problemas ligados a lo fundacional del psiquismo.The present work follows from the theoretical-clinical elaborations made from the research project of the School of Psychology of the National University of La Plata “Statutes of the body in the current forms of subjective presentation in pubescent and adolescents of the city of La Plata. Preliminary indagations”, directed by Lic. Florencia Almagro and co-directed by Lic. Andrea Elizabeth Mirc.
The analysis that we will carry out is framed within the complexity of the clinic field with children and adolescents, field that surrounds within it the times of the constitution of the psychic topic and therefore, the dimension of sexuality.
We start thinking that in the clinical approach to the problems that are found in the “limits of the analysable”, the dimension of the body rooted in different forms of psychic illness, raises questions for psychoanalysis that test their metapsychological statements, new complexities that open old problems linked to the foundational of psyche.Facultad de Psicologí
Geometric phases along quantum trajectories
A monitored quantum system undergoing a cyclic evolution of the parameters
governing its Hamiltonian accumulates a geometric phase that depends on the
quantum trajectory followed by the system on its evolution. The phase value
will be determined both by the unitary dynamics and by the interaction of the
system with the environment. Consequently, the geometric phase will acquire a
stochastic character due to the occurrence of random quantum jumps. Here we
study the distribution function of geometric phases in monitored quantum
systems and discuss when/if different quantities, proposed to measure geometric
phases in open quantum systems, are representative of the distribution. We also
consider a monitored echo protocol and discuss in which cases the distribution
of the interference pattern extracted in the experiment is linked to the
geometric phase. Furthermore, we unveil, for the single trajectory exhibiting
no quantum jumps, a topological transition in the phase acquired after a cycle
and show how this critical behavior can be observed in an echo protocol. For
the same parameters, the density matrix does not show any singularity. We
illustrate all our main results by considering a paradigmatic case, a spin-1/2
immersed in time-varying a magnetic field in presence of an external
environment. The major outcomes of our analysis are however quite general and
do not depend, in their qualitative features, on the choice of the model
studied.Comment: 20 pages, 15 figure
Estatuto y función del juego en un dispositivo pcisoanalítico con niños: una propuesta de “juego vincular”
El presente trabajo tiene como objetivo delimitar el estatuto singular que cobra el juego en el dispositivo clínico con niños y adolescentes, intentando situar los alcances y también las limitaciones que conlleva, solidario del trabajo analítico en tiempos de neogénesis del sujeto psíquico.
Hablar de juego en la clínica psicoanalítica con niños y adolescentes, lejos de ser una cuestión trillada, interpela y convoca a los psicólogos y psicoanalistas a reposicionar y repensar los fundamentos teóricos que guían su práctica, pues el modo de concebir teóricamente éstos fundamentos y, por consiguiente, sus intervenciones, dan cuenta de cómo es pensado el sujeto psíquico y su sufrimiento.
Nos centramos para profundizar en estas temáticas en la singularidad de una experiencia enmarcada dentro de un taller de juego vincular, que supone una propuesta concreta de trabajo conjunto entre niños de dos a cuatro años y sus padres, en un dispositivo clínico de carácter grupal. Este taller se lleva a cabo como parte de la propuesta terapéutica en un dispositivo de atención clínica que se desarrolla en la Fundación EICE de La Plata, específicamente, en el CEDYT (Centro de Diagnóstico y Tratamiento).The present work aims to delimit the singular status that the game collects in the clinical device with children and adolescents, trying to locate the scope and also the limitations that it entails, in solidarity with the analytical work in times of neogenesis of the psychic subject.
Speaking of play in the psychoanalytic clinic with children and adolescents, far from being a trite question, challenges and calls on psychologists and psychoanalysts to reposition and rethink the theoretical foundations that guide their practice, since the way of theoretically conceiving these fundamentals, And therefore their interventions, give account of how the psychic subject and his suffering are thought.
We focus on deepening these themes, on the singularity of an experience framed within a linking game workshop, which involves a concrete proposal of working together between children from 2 to 4 years and their parents, in a clinical device of a croup character.
This workshop is carried out as part of the therapeutic proposal in a clinical care device that is developed in the EICE Foundation of La Plata, specifically in the CEDYT (Center for Diagnosis and Treatment).Eje temático: Psicología ClínicaFacultad de Psicologí

Synergy of light harvesting and energy transfer as well as short-range charge shift reactions in multicomponent conjugates
We report herein on the design, the synthesis, and the characterization of a panchromatic, charge stabilizing electron donor-acceptor conjugate: (BBPA)3-ZnPor-ZnPc-SubPc 1. Each component, that is, bis(biphenyl)phenylamine (BBPA), Zn(ii) porphyrin (ZnPor), Zn(ii) phthalocyanine ZnPc, and subphthalocyanine (SubPc), has been carefully chosen and modified to enable a cascade of energy and charge transfer processes. On one hand, ZnPor, has been functionalized with three electron-donating BBPA as primary and secondary electron donors and to stabilize the final charge-separated state, and, on the other hand, a perfluorinated SubPc has been selected as ultimate electron acceptor. In addition, the ZnPc unit contains several trifluoromethylphenyl moieties to match its energy levels to those of the other components. In fact, irradiation of the heteroarray 1 triggers a cascade of light harvesting across the entire visible range, unidirectional energy transfer, exergonic charge separating, and short-range charge shifting to afford in 14% quantum yield a (BBPA)3+-ZnPor-ZnPc-SubPc- charge-separated state. The lifetime of the latter reaches well into the range of tens of nanosecondsFinancial support from Comunidad de Madrid, Spain (S2013/MIT-2841, FOTOCARBON), and MINECO, Spain (CTQ2017-85393-P), and the “Solar Energy goes Hybrid” Initiative of the Bavarian Ministry for Science, Culture and Education (SolTech) is acknowledge
Identification, molecular and phylogenetic analysis of poxvirus in skin lesions of southern right whale
Poxvirus skin disease has been reported in several species of cetaceans, principally in odontocetes, and a single report in mysticetes. Southern right whales Eubalaena australis in Peninsula Valdes, Argentina, show a variety of skin lesions of unknown etiology, and the number of these lesions has increased in recent years. Samples from dead whales were taken in order to establish the etiology of these lesions. One calf and one adult presented ring-type lesions, characterized by a circumscribed and slightly raised area of skin. Lesions were histologically characterized by the presence of microvesicles and vacuolated cells in the stratum spinosum, along with hyperplasia of the stratum corneum and eosinophilic inclusion bodies in the cytoplasm of the epithelial cells. Transmission electron microscopy showed aggregations of virions with typical poxvirus morphology. PCR of cetacean poxvirus (CPV) DNA polymerase, DNA topoisomerase I and parapoxvirus DNA polymerase gene fragments was done, and confirmed the presence of poxvirus in one sample. Phylogenetic analysis showed that the detected poxvirus belongs to the CPV-2 group. This is the first confirmed report of poxvirus in southern right whales in Argentina.Fil: Fiorito, Carla Daniela.

Body, social modes and adolescent psychic work
El presente trabajo tiene como objetivo sistematizar las nociones conceptuales desarrolladas en el marco del Proyecto de Investigación denominado “Estatutos del cuerpo en las formas actuales de presentación subjetiva en púberes y adolescentes de la ciudad de La Plata. Indagaciones preliminares” dirigido por las Profesoras Almagro, Florencia y Mirc, Andrea, en el que puntualizamos algunos aportes significativos que se desprenden de la construcción del marco teórico indagados hasta este momento.En tal sentido, partimos de la premisa que ordena toda indagación posible en el campo de la clínica con adolescentes, aquella que sostiene que el tiempo de la adolescencia es el tiempo donde el cuerpo recobra un protagonismo similar al de la primera infancia, asumiendo vestiduras particulares. Tiempo de resignificaciones en el campo de lo identificatorio y relacional, que tomarán los matices propios de los discursos imperantes de cada época.La referencia a lo epocal, nos obliga a servirnos de los aportes no solo ofertados por el Psicoanálisis sino también por las referencias a otros campos semánticos y discursivos tales como la Filosofía, la Sociología y la Antropología Cultural, de la mano de autores contemporáneos tales como Le Bretón, D., Chul Han, B., Bauman Z., entre otros.El cuerpo adolescente con sus marcas y transformaciones, será el escenario privilegiado en el cual se podrán leer en clave clínica los efectos de las marcas de época, ello en función de re pensar las intervenciones analíticas en su singularidad.Tal como plantean Duschatzky, S. y Coria, C. (2008) “Las formas de producción de la subjetividad no son atemporales ni universales, sino que se inscriben en condiciones sociales y culturales específicas”.¿Cuáles son las nuevas condiciones en las que las adolescencias actuales construyen su subjetividad, en un mundo surcado por las nuevas tecnologías, las redes sociales y la primacía de la imagen como modalidad de lazo social privilegiado? ¿Qué lugar particular ocupa el cuerpo en nuestra época?Estos serán algunos de los ejes que se desarrollan de manera general en el presente trabajo para compartir nuestra producción con la comunidad académica.The present work aims to systematize the conceptual notions developed within the framework of the Research Project called "Statutes of the body in the current forms of subjective presentation in pubescents and adolescents of the city of La Plata. Preliminary inquiries" directed by Professors Almagro, Florencia and Mirc, Andrea, in which we point out some significant contributions that emerge from the construction of the theoretical framework investigated so far. In this sense, we start from the premise that orders every possible inquiry in the field of the clinic with adolescents, the one that maintains that the time of adolescence is the time where the body recovers a protagonism similar to that of early childhood, assuming particular garments. Time of resignifications in the field of the identifying and relational, which will take the nuances of the prevailing discourses of each era. The reference to the epocal, forcesus to use the contributions not only offered by Psychoanalysis but also by references to other semantic and discursive fields such as Philosophy, Sociology and Cultural Anthropology, by the hand of contemporary authors such as Le Bretón, D., Chul Han, B., Bauman Z., among others. The adolescent body with its marks and transformations, will be the privileged scenario in which the effects of the epochal marks can be read in a clinical key, this in function of rethinking the analytical interventions in their uniqueness. As Duschatzky, S. and Coria, C. (2008) propose, "The forms of production of subjectivity are neither timeless nor universal, but are part ofs pecific social and cultural conditions". What are the new conditions in which today's adolescents build their subjectivity, in a world furrowed by new technologies, social networks and the primacy of the image as a form of privileged social bond? What particular place does the body occupy in our time? These will be some of the axes that are developed in a general way in this work to share our production with the academic community.Facultad de Psicologí
