Indoleamine, 2-3 dioxygenase activity could be an early marker of graft rejection in heart transplantation

[Abstract] Background. The indoleamine, 2-3 dioxygenase (IDO) is an inducible intracellular enzyme with immunosuppressive effects mainly on lymphocyte populations. It has been postulated that indirect determination of IDO serum activity may be a marker of renal graft rejection, but its potential usefulness in heart transplantation (HT) is unknown. Methods. This longitudinal study included 98 HT patients (83% males) who survived ≥1 year. Mean age was 54.14 ± 11.57 years. Serum IDO activity was analyzed one month after HT by means of high performance liquid chromatography and correlated with the cumulative incidence of acute rejection (AR) during one-year follow-up. AR was defined as biopsy-proven ≥ ISHLT grade 2R rejection or empirically treated non-biopsy-proven rejection. The study sample was divided into two groups: AR group (n = 51), including patients who experienced at least one AR episode during the first year after HT; No-AR group (N = 47), including the remaining patients. Results. Mean serum IDO activity one month after HT was significantly higher (P = .021) in the AR group (3.32 ± 1.56) than in the no-AR group (2.62 ± 1.35). No significant association between serum IDO activity and gender (male: 3.1 ± 1.56, women: 2.43 ± 0.99, P = .092), recipient age (r = −.07, P = .943) or donor age (r = 0.108, P = 0.293) was observed. By means of binary logistic regression, an odds ratio of 1.4 [CI 95%: 1.033-1.876, P = .03] per unit increase of act-IDO was estimated, with no significant modification upon forced adjustment for age and sex. Mean glomerular filtration rate 1 month after HT was 67.01 ± 28.51 mL/min/m2. No significant correlation between this parameter and serum IDO activity was observed (r = .160, P = .117). Conclusions. Our study suggests that serum IDO activity one month after HT might be associated with a higher risk of AR during one-year follow-up. This association seems to be independent of recipient gender, age or renal function

Metaanálisis del uso de semillas y aceites en la dieta de ovejas y cabras

The objective of this work was to use meta‑analysis to study the productive results of ewe and goat fed oil and seed, rich in unsatured fat acid. Twenty‑two experiments with ewes (63 treatments) and 21 experiments with goats (76 treatments) were used. Average extra fat intake was 83.6±33.6 g per day in ewes, and 73.4±38.7 g per day in goats. In ewes, extra fat intake did not affect dry matter intake, but increased milk fat yield (from 91.4 to 98.8 g per day) and reduced milk protein content (from 5.41 to 5.24%). There were no differences in the sum of fat and protein contents. In goats, extra fat included in the diet reduced dry matter intake (from 2.13 to 2.08 kg per day), and increased milk fat percentage (from 4.11 to 4.43%) and the sum of fat and protein contents (from 7.41 to 7.76%). The yield responses to the intake of diets enriched with unsaturated fatty acids differ between ewes and goats. However, milk commercial value is not affected because of the absence of negative effects on the sum of fat and protein contents in both species.El objetivo de este trabajo fue utilizar el metaanálisis para estudiar los resultados productivos de ovejas y cabras de ordeño, alimentadas con aceites y semillas ricas en ácidos grasos insaturados. Se utilizaron 22 experimentos con ovejas (63 tratamientos) y 21 con cabras (76 tratamientos). El consumo medio de grasa extra fue de 83,6±33,6 g por día en ovejas y 73,4±38,7 g por día en cabras. En ovejas, la grasa extra no afectó al consumo de materia seca, pero aumentó la producción de grasa (de 91,4 a 98,8 g por día) y redujo el contenido proteico (de 5,41 a 5,24%) de la leche. No hubo diferencias en el extracto quesero. En cabras, la inclusión de grasa en la dieta redujo el consumo de materia seca (de 2,13 a 2,08 kg por día) y aumentó el porcentaje de grasa láctea (de 4,11 a 4,43%) y el extracto quesero (de 7,41 a 7,76%). La respuesta productiva de ovejas y cabras al consumo de dietas ricas en ácidos grasos insaturados es diferente. Sin embargo, el valor comercial de la leche no se ve afectado, debido a la ausencia de efectos negativos sobre el extracto quesero en ambas especies

Actions for novel teacher training: design and implementation of learning activities and resources on LMS support

El presente artículo describe el desarrollo de un Proyecto formativo para la implementación de actividades y recursos de aprendizaje en la plataforma UCO-Moodle por parte de profesorado novel, bajo tutela y coordinación de profesorado con experiencia previa contrastada. Se trata de un trabajo multidisciplinar donde las acciones se han ejecutado para ocho asignaturas de cuatro Áreas de conocimiento. El impacto de las innovaciones introducidas en varias asignaturas, afectó a más de 500 alumnos pertenecientes a seis títulos de grado de la Universidad de Córdoba. El trabajo realizado se completó con una evaluación de satisfacción por parte de los alumnos de los nuevos recursos de aprendizaje así como la autoevaluación del profesorado novel sobre la experiencia desarrollada.This article describes a project for the implementation of learning activities and resources in the UCO-Moodle platform by training teachers has been developed under the supervision and coordination of senior teaching staff with proven previous experience. It is a multidisciplinary work where the actions have been executed for eight different subjects in four Areas of knowledge. The impact of the learning activities introduced in different subjects was extended to more than 500 students belonging to six undergraduate degrees from the University of Cordoba. The experience has included an evaluation of students' satisfaction with the new learning resources as well as the self-assessment of the new teaching staff on the executed actions
