Abstract: Se evaluó el efecto de un dispositivo intravaginal conteniendo progesterona más una inyección de prostaglandina F2α (PGF2α) al retiro del dispositivo y la aplicación de Gonadotrofina Coriónica humana (hCG) al día 5 post retiro sobre la actividad ovárica en yeguas cíclicas. Adicionalmente, se evaluaron los porcentajes de pre ez. Los animales se dividieron en: grupo T: animales tratados a partir del día 0 con dispositivo intravaginal conteniendo 1,38 g de progesterona durante 8 días más aplicación de PGF2α al retiro y al 5to día hCG a aquellos animales con un folículo ≥ 30 mm y grupo C: animales controles; sin tratamiento. Al 4to día post retiro los animales fueron puestos en servicio por monta natural en manada. El dispositivo indujo concentraciones plasmáticas de progesterona superiores a 2,1 ng ml-1 durante su exposición. En el 83,4% de los animales del grupo T (25/30) se observó la presencia de un folículo ovulatorio entre el retiro del dispositivo y el día de inyección de hCG: el 68% (17/25) ovuló como respuesta a la hCG, mientras que el 32% (8/25) lo hizo espontáneamente en los primeros 4 días post retiro. En los animales controles se registraron ovulaciones aleatoriamente. Al día 45 del retiro, la ecografía demostró un mayor porcentaje de yeguas pre adas en los primeros días post tratamiento en el grupo T, aunque las diferencias no fueron estadísticamente significativas. Se concluye que la utilización de un dispositivo intravaginal en el protocolo descripto, resulta en una importante sincronización de la aparición de folículos ovulatorios alrededor del 5to día post retiro. The aim of the present study was to evaluate the effect of a progesterone releasing intravaginal device plus the injection of PGF2α at removal and the application of hCG on day 5 after withdrawal on the ovarian activity in cyclic mares. Additionally, pregnancy rates were evaluated at the end of the study. Animals were divided into two groups: Treated with an intravaginal device containing 1.38 g progesterone during 8 days plus PGF2α at the removal time and an hCG injection to animals with a follicle with a diameter ≥ 30 mm on day 5 and controls (no treatment). Four days after removal, animals were mated. Plasma progesterone concentrations remained 2.1 ng ml-1 during the period that the devices were kept into the vagina. An ovulatory follicle between the device removal and hCG application was observed in 83.4% (25/30) of the treated animals: 68% (17/25) ovulated in response to hCG while 32% (8/25) ovulated spontaneously during the first 4 days post device removal. In the control g

Sovremennye Tehnologii v Medicine , 2010,
Abstract: Aim of investigation is establishment of the lethal thrombosis and attendant complication development reasons and mechanisms after operations of the univentricular heart hemodynamic correction: a high significance of pressure in a pulmonary artery prior to operation, execution of multiple operations and, particularly, the pulmonary artery stenosis operations, a complicated anatomy of disease and attendant anomalies of development, and a bronchopulmonary pathology.Materials and methods. The case histories from the infantile surgical center, the Cardiology RSPC infantile age cardiosurgery department archives were a subject of investigation; a retrospective analysis is made.

Bìologì?nij Vìsnik Melìtopol?s?kogo Der?avnogo Pedagogì?nogo Universitetu ìmenì Bogdana Hmel?nic?kogo , 2012,
Abstract: The research was performed in the area of natural reserve "Dneprovsko-Orelsky" and its adjacent territory – the island Pogorely. We discovered the changes of number of grey heron in colonial settlements, determined the principal factors influencing the formation of spatial structure of island bird communities. The analysis of nest distribution towards tree breeding biotopes was performed and stability of spatial structure of bird colonies was proved. We were tracking the number dynamics of pioneer colony and revealed the principal ecological and anthropogenic factors influencing the fluctuation of its abundance.

Abstract: When comparing the suggested stability indicators, we obtained statistically significant correlations for indicators of annual stability of species and total number and standard deviation of the logarithm of the number. Annual Stability Index can be applied with a high degree of reliability as a characteristic of the averaged structure of the community and its pyramid of abundances. The results of correlation analysis confirm our assumptions about the correlation between stability over the years and indices of species diversity and relative uniformity.The final task of the study was to create a mathematical model of stability, where the independent variables are the indices of species diversity. The calculation of these indices allows forecasting birds’ community stability. According to the result of multiple regression for the indicators of diversity and stability of the breeding birds’ community highest correlation coefficients were obtained fro Shannon index and Simpson's dominance Index.Community stability could be determined by its overall species diversity. When considering the stability of community its diversity should be considered as a combination of uniformity of their total number and number of species. The most suitable predictors for the community stability were the nonparametric index of dominance and information-statistical indices, since they considered simultaneously evenness and richness. The community stability is subject of the complexity of its internal communications pattern.
