Evaluación de la involución, salud uterina y retorno de la actividad ovárica con la adición de zeolita 2% en la dieta basal de vacas lecheras

El objetivo de esta investigación fue evaluar el efecto de zeolita (Clinoptilolita) adicionado en la dieta basal de vacas lecheras durante 105 días, 60 días pre-parto (dap) y 45 días post-parto (dpp) y su influencia en la involución (IU) y salud uterina (SU), el retorno de la actividad ovárica (AO) y la condición corporal (CC). El proyecto se realizó en tres ganaderías de la comunidad de Soldados del Cantón Cuenca – Azuay, en 50 vacas secas, con una CC ≥ 3,5, entre 2 a 5 partos, clínicamente sanas y todas en las mismas condiciones sanitarias y de manejo; fueron divididas en un grupo control (n1=25), alimentadas con dieta basal y un experimental (n2=25), con dieta basal + 2% de Zeolita del consumo de materia (CMS). Se evaluó retorno de AO considerando folículos ≥ 10 mm de diámetro a los 15, 22, 35 y 45 dpp por Ultrasonografía transrectal, SU (>10 PMN) a los 35 dpp por cytobrush, IU considerando posición del útero con respecto a la pelvis (PU), simetría de los cuernos (SCU), y diámetro del cérvix (DC), a los 22 y 45 dpp por palpación rectal, y finalmente la CC a los 15 dap, parto y 45 dpp. Se usó un diseño completamente al azar (DCA) y los resultados fueron analizados con el programa estadístico SPSS versión 22.0, posteriormente fueron aplicados los estadísticos de “U de Mann Withney y Kruscall Wallis”. Se obtuvo eficacia en el GE con mayor porcentaje de vacas que retornaron su AO (respectivamente, para GC y GE fueron: 35 dpp 29,6% vs. 70,4%; 45 dpp 44,4% vs. 55,6%; p<0,05). La IU fue a los 45 dpp, los valores obtenido para GC y GE fueron: respectivamente, PU 40,0% vs. 76,0%, SCU 32,0% vs. 76,0% y DC 28,0% vs. 68,0%, (p<0,05). Y en SU también mostró eficacia en el GE obteniendo un 3,4% vs. 22,2% de PMN en comparación con el GC, (p<0,05). Finalmente, se comprobó diferencias significativas (p<0,05) en la CC al parto y 45 dpp con eficacia atribuida al GE. En conclusión, la adición de zeolita al 2% en la dieta basal mostró eficacia en la involución y salud uterina, retorno de la actividad ovárica y la condición corporal en vacas en transición, recomendando su uso en las ganaderías lecheras

The reproductive biology of Spondyliosoma cantharus (L.) from the SW Coast of Portugal

The study of Spondyliosoma cantharus (L.) reproduction was carried out within the framework of a project on the Fisheries resources of the south-west coast of Portugal, and was based on the analysis of the spawning season, gonad maturation, size-at-maturity, fecundity, and hermaphroditism. Spawning took place from February to April, peaking in March. Analysis of the sex ratio by size class and season showed that females were more abundant throughout the year (M/F=0.57) and in the smaller size classes. Overall size at first maturity (L-50) was 20.10 cm total length (TL), with a significant difference between males (22.41 cm, TL) and females (19.98 cm, TL). Absolute fecundity (Fa) ranged from 37,506 to 112,074 oocytes, with a mean of 61,396. A power type relationship best described the relationships between absolute fecundity and TL (Fa = 436.27TL(1.575)), and somatic weight (Fa = 2979.7SW(0.585)). The number of oocytes/g of female somatic weight ranged from 217 to 549, with a mean of 346. The reproductive strategy of this species is characterised by protogynic hermaphroditism, as indicated by the presence of individuals in transition and of testes with vestiges of preceding ovaries associated with the significant differences in the size frequency distributions of the sexes.

“¡Pero al fin y al cabo muñecas!”: Tránsitos, genitalidades y nombramientos en las trayectorias de vida de mujeres transexuales en ejercicio de prostitución en Bogotá

El presente trabajo comprende la construcción de las trayectorias de vida de cinco mujeres transexuales en ejercicio de prostitución en Bogotá a partir de la identificación de los desplazamientos en el terreno corporal, de auto-reconocimiento y de genitalidad en sus procesos de transformación y/o tránsito dentro del espacio generizado. La identificación de lo que he denominado “agentes de transformación específicos” y “condiciones de posibilidad existentes” guía el proceso de la caracterización y análisis de sus experiencias dentro de la(s) transexualidad(es). A diferencia de una línea cronológica o de avance en el tránsito, la noción de espacio generizado me permite reconocer la importancia de las diferencias, la complejidad y la variedad de velocidades y direcciones que pueden presentarse en las experiencias con el cuerpo.

Las reparaciones simbólicas en escenarios de justicia transicional

Resumen Cuando una sociedad intenta hacer una transición de situaciones de conflicto armado a paz o de regímenes dictatoriales a democracias, debe tomar decisiones políticas que garanticen los estándares internacionales en materia de derechos de las víctimas de violaciones a derechos humanos, pero que permitan pactos entre las partes implicadas. En este contexto el derecho a la reparación es el centro de álgidos debates. Por eso, en este artículo se propone visibilizar las reparaciones simbólicas como parte de la reparación integral y como importante mecanismo para que las sociedades en transición logren superar los hechos victimizantes sin olvidarlos y para que estos no se repitan; entonces, los simbolismos reparadores buscarán nombrar y dignificar a las víctimas, recordar la verdad y solicitar perdón asumiendo responsabilidades. Abstract When a society tries to make the transition from armed conflict to peace, or dictatorships to democracies, political decisions must be taken to ensure international standards concerning the rights of victims of human rights violations, but allowing agreements between the parts involved. In this context, the right to reparation is the peak center of discussions.So, this article proposes to visualize the symbolic reparations as part of the internal reparation and as an important mechanism so that societies in transition can overcome the victimizing facts without forgetting them, and in order to stop them too. Then, the repairing symbolism would seek to appoint and dignify the victims, to remember the truth, taking responsibilities, and asking for forgiveness.

Le nuove forme di genitorialità tra vincoli biologici, verita legale e legami affettivi

Le recenti novelle e l’evoluzione delle tecniche riproduttive scientifiche hanno promosso un progressivo processo di frammentazione della figura genitoriale, che sino ad allora era considerata unitaria ed intimamente connessa all’incontro tra uomo e donna. A tale concezione unitaria del legame genitoriale corrispondeva la considerazione che la coincidenza tra vincolo genetico e verità legale fosse foriera del soddisfacimento del superiore interesse del minore. La genitorialità può ad oggi essere suddivisa tra genetica, qualora tra il genitore condivida con il figlio il medesimo patrimonio genetico; biologica, nell’accezione di gestazionale e dunque caratterizzante il rapporto tra madre e figlio; e sociale, qualora l’adulto, seppur in mancanza di un titolo legale e altrettanto di un legame di sangue con il figlio, adempie ai doveri di cura e di mantenimento propri dell’esercente la responsabilità genitoriale. A fronte della pluralità dei soggetti che latu senso possono essere considerati genitoriali in forza di una pluralità e eterogeneità di legami, l’interprete deve interrogarsi circa la effettività e la cogenza delle tradizioni definizioni di madre e di padre e soprattutto la resilienza dei criteri attributivi dello stato di filiazione.

Novel developments of atropisomeric organic molecules. Design of atropisomeric drugs, fluorescent compounds and investigation of reaction mechanisms.

In recent years, the study of restricted rotation bonds in organic compounds has aroused increasing interest. The reason is that this characteristic can lead to obtaining new properties in organic compounds. In this research thesis, an intense investigation was carried out using DFT calculations and experimental evaluation of the barriers to rotational energies, in order to discover new properties deriving from the restricted rotation bonds. Research has been developed in various fields of organic chemistry, ranging from drugs (the atropisomeric atorvastatin in Chapter 3) to luminescent compounds (aryls amino borane in Chapter 4). Furthermore, an organocatalytic central to axial conversion mechanism was investigated through DFT calculations, finding out interesting outcomes (Chapter 5). Finally, a project in collaboration with Dr. Farran and Prof. Vanthuyne of the Aix-Marseille University was done to investigate the interactions in transition states of rotational barriers.

L'identita visiva pubblica. Nuovi paradigmi di comunicazione

La ricerca proposta affronta il tema dell’identità visiva — uno dei più caratterizzanti e complessi del progetto di comunicazione — applicato alla dimensione pubblica, partendo dalla comprensione e dalla misurazione del profondo mutamento che ha portato alla sua trasformazione da stemma a marchio e poi a logo, da immagine coordinata a brand a progetto di service e experience. La ricognizione dell’evoluzione della comunicazione pubblica e l’analisi del contesto dell’eredità culturale della “grafica di pubblica utilità” forniscono il primo framework di indagine nel quale si prospetta una lettura della complessità della trasformazione del progetto di identità visiva come occasione per un suo ripensamento. Un secondo framework è individuato nel contesto della comunicazione pubblica italiana in cui l’organizzazione e la progettazione di un sistema “istituzione-design-cittadino” è ancora in transizione. L’analisi dell’evoluzione normativa, dei touchpoint, delle pratiche progettuali, degli strumenti e dei ruoli permette di inquadrare gli attuali spazi e paradigmi di interazione che vedono nel servizio digitale la forma prevalente di relazione tra cittadini e dimensione pubblica Attraverso l'esperienza diretta, l’analisi dei casi studio come strumento di indagine e la sistematizzazione di cinque cluster, la tesi propone una rinnovata definizione di identità visiva pubblica che, distaccandosi da una predominante connotazione marketing-oriented, sia funzionale alla costruzione di esperienze utili, e percezioni di queste, rafforzando e stimolando nuovi paradigmi di relazione tra cittadini e dimensione pubblica. Si propone inoltre una prospettiva progettuale che evolve dalla necessità di individuare nuovi percorsi e modalità di rapportarsi con il progetto di pubblica utilità e per la cittadinanza che rifuggono la manifestazione dell’equivoco - piuttosto comune nel contesto pubblico italiano - del confrontarsi con i cosiddetti «wicked problems» (Buchanan, 1992) ricercando, in termini di comunicazione pubblica soluzioni chiuse ed esclusivamente formali, ritenendo che queste possano avere una reale efficacia nel plasmare i rapporti tra cittadini e dimensione pubblica.

Attachment style and coping resources as predictors of coping strategies in the transition to parenthood

The relations among adult attachment style, coping resources, appraised strain, and coping strategies were examined in a prospective study of married couples having their first child (N = 92). Attachment and coping resources were measured during the second trimester of pregnancy, and parenting strain and coping strategies were assessed when the babies were about 6 weeks old. Results supported a theoretical model proposing that attachment is predictive of coping resources and appraised strain, and that attachment, resources, and strain are predictive of coping strategies. Results also highlighted the complexity of associations among attachment, stress, and coping: Gender differences in mean scores and predictive associations were obtained, and some interactions were found between resources and strain in predicting coping strategies. The findings support the utility of integrating theories of attachment and coping in explaining couples' adjustment to important developmental transitions.

Family interactions in IVF families: change over the transition to parenthood

Objective: This article presents a study of the change over time in the family interactions of couples who conceived through in-vitro fertilisation (IVF). Background: Observational methods are rarely used to study family interactions in families who used assisted reproductive techniques, but these methods are crucial for taking account of the communication that occurs in interactions with infants. Methods: Thirty-one couples expecting their first child were seen during the fifth month of pregnancy and when the child was nine months old. Family interactions were recorded in pre- and postnatal versions of the Lausanne Trilogue Play situation. Measures of marital satisfaction and parent-to-foetus/baby attachment or 'bonding' were also used to assess family relational dynamics. Results: Results showed that family alliance, marital satisfaction and parental attachment scores in the IVF sample were all similar to or higher than those in the reference sample during pregnancy. However, at nine months postnatally, the family alliance scores were lower. While marital satisfaction decreased over the period and parent-baby attachment increased, the family alliance scores were unstable, as no association was observed between the pre- and postnatal scores. In addition, neither prenatal marital satisfaction nor parent-foetus attachment predicted the postnatal family alliance. Conclusion: The change in the family alliance over the transition to parenthood appears to be specific to our IVF sample. Given that postnatal family functioning could not be predicted by prenatal family functioning, our observational data underline the importance of offering postnatal support to these families.
