Reproductive Behavior of Jersey Cattle Breed.

The reproductive features of Jersey cattle breed were determined, and the non-genetic factors that affected the features, service period (days), calving interval (days), gestation length  (days), and gestation service per insemination performed, were assessed. Records of  150 calvings between  204 and 2013 at Los Pinos  UEB, Triangulo Tres  Cattle Raising Company, in Camagüey, Cuba, were used. The cows were inseminated with semen from the same breed. SPSS, version 11.5, was used to  calculate the basic statgraph, analyze variable normality (Kolmogorov-Smirnov test), the Levene´s test, and multiple linear analyses of variance for each dependent variable.  The non-genetic factors that affected the service period and calving interval were  the calving  number, season, and year.  The values achieved for the service period features and calving interval were  259.2 ± 13.2, and 539.8 ± 13.2 days, respectively. The dura-tion of gestation (280.6 ± 1.6 days), and gestation service (2.2 ± 0.2 services  performed) were not affected by any of the non-genetic effects studied

Comportamiento reproductivo de la raza Jersey.

Se determinaron los rasgos reproductivos (período de servicio, intervalo parto-parto, duración de la gestación y servicio por gestación) de la raza Jersey y se valoraron los factores no genéticos que los afectaron. Se utilizaron los registros de 150 partos ocurridos entre 2004 y 2013, en la UEB Los Pinosde la Empresa Pecuaria Triángulo Tres, Camagüey, Cuba. Las vacas fueron inseminadas con semen de toros de la misma raza. Se utilizó el paquete estadísti-co SPSS, versión 11,5, para calcular los estadígrafos básicos, analizar la normalidad de las variables (test de Kolmo-gorov-Smirnov). Se realizó la prueba de Levene y un análisis de varianza lineal múltiple para cada variable dependiente. Los factores no genéticos que afectaron al período de servicio e intervalo parto-parto fueron: el número de partos, época y año del parto. Los valores obtenidos para los rasgos período de servicio e intervalo parto-parto fue-ron: 259,2 ± 13,2 y 539,8 ± 13,2 días, respectivamente. La duración de la gestación (280,6 ± 1,6 días) y el servicio por gestación (2,2 ± 0,2 servicios realizados) no fueron afectados por ninguno de los efectos no genéticos estudiados. Jersey Breed Reproductive Performance. ABSTRACT Reproductive traits affected by non-genetic factors were determined for Jersey breed herds on Los Pinos dairy farm from Triángulo Tres Livestock Center in Camagüey, Cuba. Data from 150 calving registered between 2004 and 2013 were analyzed. Performance of reproductive traits, i.e., calving to pregnancy interval, calving interval, preg-nancy span, and services per pregnancy, was evaluated. Cows were artificially inseminated with semen from Jersey-breed sires. Version 11.5 SPSS software program was used to estimate basic statisticians and analyze variables nor-mal range (Kolmogorov-Smirnov’s test). Each independent variable was performed the Levene’s test and a multiple linear analysis of variance. Results indicated that non-genetic factors affecting calving to pregnancy interval (259,2 ± 13,2 days) and calving interval (539,8 ± 13,2 days) were calving number, season, and year. However, no ef-fect from non-genetic factors on pregnancy span and services per pregnancy was found

Accurate ρ̄ and log g of δ Sct stars using Asteroseismology

In this work, we present a new method to determine the surface gravity of δ Sct stars. We used a refined Δν=ρ̄ relation and the stellar parallaxes or luminosities to determine their masses and radii. A comparison with the data obtained from the binary analysis, has shown that the values found by both methods are equivalent, within the uncertainties. Moreover, thanks to the refined relation, the uncertainties in log g are of the order of those usually estimated with high-resolution spectroscopy. Because of that, this new method to determine the surface gravity is an important step forward to break the degeneracy problem in the spectroscopic analysis.AGH acknowledges support from Fundação para a Ciência e a Tecnologia (FCT,Portugal) through the fellowship SFRH/BPD/80619/2011 and from grant UID/FIS/04434/2013.AGH, MJPFGM and JCS acknowledge support from the EC Project SPACEINN (FP7-SPACE-2012-312844) .JCSalsoacknowledges funding support from the Spanish “Ministerio de Economía y Competitividad” under“Ramón y Cajal”subprogram.

Seed storage conditions change the germination pattern of clonal growth plants in Mediterranean salt marshes.

8 páginas, 4 tablas, 8 figuras.The effect of salinity level and extended exposure to different salinity and flooding conditions on germination patterns of three saltmarsh clonal growth plants (Juncus subulatus, Scirpus litoralis, and S. maritimus) was studied. Seed exposure to extended flooding and saline conditions significantly affected the outcome of the germination process in a different, though predictable, way for each species, after favorable conditions for germination were restored. Tolerance of the germination process was related to the average salinity level measured during the growth/germination season at sites where established individuals of each species dominated the species cover. No relationship was found between salinity tolerance of the germination process and seed response to extended exposure to flooding and salinity conditions. The salinity response was significantly related to the conditions prevailing in the habitats of the respective species during the unfavorable (nongrowth/nongermination) season. Our results indicate that changes in salinity and hydrology while seeds are dormant affect the outcome of the seed-bank response, even when conditions at germination are identical. Because these environmental-history-dependent responses differentially affect seed germination, seedling density, and probably sexual recruitment in the studied and related species, these influences should be considered for wetland restoration and managementFinancial support from the Spanish Ministry of the Environment (MMA, project 05/99) and the Junta de Andalucía (research group 4086)enabled us to carry out the present work.Peer reviewe

Usefulness of midregional proadrenomedullin to predict poor outcome in patients with community acquired pneumonia.

midregional proadrenomedullin (MR-proADM) is a prognostic biomarker in patients with community-acquired pneumonia (CAP). We sought to confirm whether MR-proADM added to Pneumonia Severity Index (PSI) improves the potential prognostic value of PSI alone, and tested to what extent this combination could be useful in predicting poor outcome of patients with CAP in an Emergency Department (ED).Consecutive patients diagnosed with CAP were enrolled in this prospective, single-centre, observational study. We analyzed the ability of MR-proADM added to PSI to predict poor outcome using receiver operating characteristic (ROC) curves, logistic regression and risk reclassification and comparing it with the ability of PSI alone. The primary outcome was "poor outcome", defined as the incidence of an adverse event (ICU admission, hospital readmission, or mortality at 30 days after CAP diagnosis).226 patients were included; 33 patients (14.6%) reached primary outcome. To predict primary outcome the highest area under curve (AUC) was found for PSI (0.74 [0.64-0.85]), which was not significantly higher than for MR-proADM (AUC 0.72 [0.63-0.81, p > 0.05]). The combination of PSI and MR-proADM failed to improve the predictive potential of PSI alone (AUC 0.75 [0.65-0.85, p=0.56]). Ten patients were appropriately reclassified when the combined PSI and MR-proADM model was used as compared with the model of PSI alone. Net reclassification improvement (NRI) index was statistically significant (7.69%, p = 0.03) with an improvement percentage of 3.03% (p = 0.32) for adverse event, and 4.66% (P = 0.02) for no adverse event.MR-proADM in combination with PSI may be helpful in individual risk stratification for short-term poor outcome of CAP patients, allowing a better reclassification of patients compared with PSI alone
