Estudio de la muerte celular por Apoptosis en el ovario de Columba maculosa y Columbina picui (Aves:Columbidae) durante el Ciclo Reproductivo Anual. Study of cell death by apoptosis in the ovary of Columba maculosa and Columbina picui (Aves: Columbidae) during the reproductive annual cycle.

En este trabajo se analizarán las características estructurales, cuantitativas y el proceso de muerte celular por apoptosis en el ovario de C. maculosa y C.picui con el objetivo de aportar conocimientos básicos a la biología reproductiva de estas aves. Cincuenta hembras adultas de cada especie se capturarán en el Dpto. Río Primero (Pcia. de Cba), R. Argentina, durante el ciclo reproductivo 2011-2012. Las muestras de ovarios se fijaran en Formalina Neutra pH 7.0, procesarán con la técnica de inclusión en parafina y colorearan con Hematoxilina /Eosina y Reacción Nuclear de Feulgen. Cinco muestras serán utilizadas para la determinación de muerte celular por apoptosis con la técnica de TUNEL. Se estudiarán las características morfohistológicas del ovario de C.maculosa y C. picui e identificarán, categorizarán y cuantificarán los folículos atrésicos no bursting (folículos atrésicos previtelogénicos y vcitelogénicos pequeños que conservan la integridad de la pared folicular) y bursting (folículos vitelogénicos mayores de 2 mm que liberar el contenido folicular por ruptura de la pared folicular) durante el ciclo reproductivo anual. Mediante la marcación de ADN fragmentado, se revelará la muerte celular por apoptosis en las células granulosas de los folículos atrésicos. Se compararán las semejanzas y diferencias estructurales y cuantitativas y el proceso de muerte celular en los folículos regresivos entre las dos especies. Los resultados de este trabajo representarán un importante aporte al conocimiento de la atresia folicular como así también a la muerte celular, un proceso estrechamente asociado a la misma, aún poco estudiado en el ovario de las aves. In this work we analyse the structural, quantitative and the process of the cell death by apoptosis in the ovary of Columba maculosa and Columbina picui in order of providing basic knowledge of reproductive biology of these birds. Fifty adult female of each species will be caught in the Río Primero (Pcia. Cba) R.Argentina, during 2011 - 2012. The ovarian samples will be fixed en neutral buffered Formalin (pH 7.0), processed with the technique of inclusion in paraffin and stained with Haematoxylin - Eosin, and nuclear Reaction of Feulgen. Five samples will be used to reveal cell death by apoptosis with the technique of TUNEL. Will be studied the morphohistological characteristics of ovary of both species, and identify, categorize and quantify the atretic follicles over the cycle, the non-bursting (pre-vitellogenic follicles and vitellogenic small < 2 mm, involution an without follicular rupture) and bursting (vitellogenic follicle > 2 mm in the which the yolk falls into the peritoneum due to rupture of with out put of the wall follicular). Will be revealed DNA fragmentation in the granulosa cells of the atretic follicles. Will compared the similaritues and differences in structure and quantitative and the cell death process by apoptosis in the regresive follicles, between the two species. The results of this study represent an important contribution to the knowledge of follicular atresia as well cell death a process closely associated with it and still poorly studied in the ovary of birds.

Development of a life cycle management system for remote products.

The research described in this thesis has been developed as a part of the Reliability and Field Data Management for Multi-Component Products (REFIDAM) Project. This project was funded under the Applied Research Grants Scheme administered by Enterprise Ireland. The project was a partnership between Galway-Mayo Institute of Technology and an industrial company, Thermo King Europe. The project aimed to develop a system to manage the information required for maintenance costing, cost of ownership, reliability assessment and improvement of multi-component products, by establishing information flows between the customer network and across the Thermo King organisation.

The effects of detergent loading on rotating biological contactor (RBC) wastewater treatment efficiency

There are presently over 182 RBC plants, treating domestic wastewater, in the Republic of Ireland, 136 of which have been installed since 1986. The use of this treatment plant technology, although not new, is becoming increasingly popular. The aim of this research was to assess the effects that a household detergent has on rotating biological contractor treatment plant efficiency. Household detergents contribute phosphorus to the surrounding environment and can also remove beneficial biomass from the disc media. A simple modification was made to a conventional flat disc unit to increase the oxygen transfer of the process. The treatment efficiency of the modified RBC (with aeration cups attached) was assessed against a parallel conventional system, with and without degergent loading. The parameters monitored were chemical oxygen demand (COD), bio-chemical oxygen demand (BOD), nitrates, phosphates, dissolved oxygen, the motors power consumption, pH, and temperature. Some microscopic analysis of the biofilm was also to be carried out. The treatment efficiency of both units was compared, based on COD/BOD removal. The degree of nitrification achievable by both units was also assessed with any fluctuations in pH noted. Monitoring of the phosphorus removal capabilities of both units was undertaken. Relationships between detergent concentrations and COD removal efficiencies were also analysed.

Sex-Specific Equations to Estimate Maximum Oxygen Uptake in Cycle Ergometry

AbstractBackground:Aerobic fitness, assessed by measuring VO2max in maximum cardiopulmonary exercise testing (CPX) or by estimating VO2max through the use of equations in exercise testing, is a predictor of mortality. However, the error resulting from this estimate in a given individual can be high, affecting clinical decisions.Objective:To determine the error of estimate of VO2max in cycle ergometry in a population attending clinical exercise testing laboratories, and to propose sex-specific equations to minimize that error.Methods:This study assessed 1715 adults (18 to 91 years, 68% men) undertaking maximum CPX in a lower limbs cycle ergometer (LLCE) with ramp protocol. The percentage error (E%) between measured VO2max and that estimated from the modified ACSM equation (Lang et al. MSSE, 1992) was calculated. Then, estimation equations were developed: 1) for all the population tested (C-GENERAL); and 2) separately by sex (C-MEN and C-WOMEN).Results:Measured VO2max was higher in men than in WOMEN: -29.4 ± 10.5 and 24.2 ± 9.2 mL.(kg.min)-1 (p < 0.01). The equations for estimating VO2max [in mL.(kg.min)-1] were: C-GENERAL = [final workload (W)/body weight (kg)] x 10.483 + 7; C-MEN = [final workload (W)/body weight (kg)] x 10.791 + 7; and C-WOMEN = [final workload (W)/body weight (kg)] x 9.820 + 7. The E% for MEN was: -3.4 ± 13.4% (modified ACSM); 1.2 ± 13.2% (C-GENERAL); and -0.9 ± 13.4% (C-MEN) (p < 0.01). For WOMEN: -14.7 ± 17.4% (modified ACSM); -6.3 ± 16.5% (C-GENERAL); and -1.7 ± 16.2% (C-WOMEN) (p < 0.01).Conclusion:The error of estimate of VO2max by use of sex-specific equations was reduced, but not eliminated, in exercise tests on LLCE.
