Evaluación de la capacidad y condición reproductiva de la Merluza (Merluccius gayi peruanus)

Se estudia los aspectos más significativos de la biología reproductiva de la merluza Merluccius gayi peruanus, información que puede servir como punto de partida para la determinación del stock desovante, mediante la aplicación del método de producción de huevos. El material estuvo constituido por 210 ejemplares colectados en setiembre de 1987 a bordo de los barcos de arrastre costero con base en el Puerto de Paita y de información biológica proveniente de los muestreos que se efectuaron en el Laboratorio Regional de Paita, entre enero de 1984 y diciembre de 1986. El análisis de las gónadas. determinado por la distribución de frecuencias de los diámetros ovulares y por observaciones histológicas, señalan a la merluza como una especie de desarrollo ovocitario asincrónico lo que le dá el carácter de desovador parcial. Se comprobó que el IGS, es el complemento numenco que mejor describe, en forma empírica, la actividad sexual; el análisis mensual permitió d-eterminar que en los años de 1984- 1986 el desove principal se produjo en invierno-primavera, sin observarse muy definido el pico secundario correspondiente a los meses de verano. Mediante el recuento de oocltos hidratados, se pudo determinar la fecundidad modal que alcanza valores promedio de 117 227. Se determinó el peso gonadal como la variable para estimar la fecundidad por su mayor correlación.

Comparison of potential adjustment variables representing primary intellectual level in epidemiological studies on neurotoxicity

BACKGROUND: Primary intellectual abilities (PIA) are a confounder in epidemiological studies on neurotoxicity. A good measure of this confounder should be independent of age as PIA is an intrinsic ability. Furthermore, as PIA is related to health endpoints, any measure of PIA should reveal this association. This study is aimed at comparing vocabulary test, diploma and age at end of schooling properties as measures of PIA in a non-exposed population of workers. METHODS: The design was a cross-sectional study of 413 non-exposed workers (203 women and 210 men) selected from a health check-up center. The effect of age on the vocabulary score was assessed using an analysis of covariance adjusted for diploma. Relationships between neuropsychological performances and vocabulary score, diploma and end of schooling age were, respectively, assessed using multiple linear regressions adjusted for age and gender. RESULTS: Vocabulary score increased significantly with age, both for men and women. The increase was 0.14 word per year for women, and 0.18 word per year for men. The explained variance of the models evaluating the relationships between age at end of schooling, diploma, vocabulary test, and neuropsychological performances was quite similar for the three measures of PIA. CONCLUSIONS: Vocabulary score was found to be age-related, even after adjustment for diploma. No difference was found between these three variables in terms of their relationship to neuropsychological endpoints. Moreover, the literature shows that vocabulary test performances are influenced by exposure to neurotoxic agents. These results suggest that vocabulary score could be of interest for participants of similar ages and similar diplomas. Otherwise, the other two variables would be better PIA measures in neurotoxicology studies.

Performance Report for Fiscal Year, 2007

I am pleased to present the performance report for the Iowa Department for the Blind for fiscal year 2007. This report is provided in compliance with sections 8E.210 and 216B.7 of the Code of Iowa. It contains valuable information about the services the Department and its partners provided for Iowans during the past fiscal year in the areas of Vocational Rehabilitation, Independent Living, Library Services, and Resource Management. The Department determines its competitive success in a number of ways. We look at the federal standards and indicators to learn our ranking in relation to the performance of other public rehabilitation agencies. We compare our library's production and circulation figures with those from previous years to determine trends. We set our own standards for success by looking at such factors as the number of successful case closures, average hourly wage at case closure, skills training provided, and compliance with regulations. Results show that the Department is working positively toward achieving its strategic goals of increasing the independence and productivity of blind Iowans and improving access to information for blind Iowans. Major accomplishments of the year included the selection of our Library as the only agency authorized to distribute educational materials using the National Instructional Materials Accessibility Standard (NIMAS) to students in Iowa. Our Independent Living program received the Shining Star award at the Governor's Conference on Aging for its work with and outreach to older blind Iowans. The Department, the Iowa Braille School, and the Department of Education implemented new cooperative efforts to improve the coordination and delivery of services to blind and visually impaired students in Iowa. Finally, earnings ratios and the percentage of employment for vocational rehabilitation clients of the Department remain among the best in the nation, as measured by the U.S. Rehabilitation Services Administration, which on June 27, 2007 released data on federal standards and indicators for the year ended September 30, 2006. Overall, we met or exceeded 11 of 16 results targets included in this report. A discussion of the Department's services, customers, organizational structure, and budget appears in the "Department Overview" that follows. The success of the Department's programs is evident in the success achieved by blind Iowans. It is reflected in the many blind persons who can be seen traveling about independently, going to their jobs and to the community and family activities in which they participate. Sincerely, Allen C. Harris Director, Iowa Department for the Blind

Taking Chances on Integrity: An Investigation of the Iowa Lottery

The Iowa Lottery has failed to adequately protect its customers from fraud and theft by retailers. That is the key conclusion of the Iowa Citizens’ Aide/Ombudsman in a critical report released today. The 210-page report, which makes 60 recommendations to the Lottery, is the culmination of a year-and-a-half-long investigation into how the Lottery polices and prevents retailer fraud and theft. In general, the Ombudsman found that the Lottery has maintained a weak, reactive enforcement system that fails to detect retailer dishonesty independently of customer complaints. This means that there likely have been instances of fraud – possibly largescale fraud – that have gone undetected. The Ombudsman’s examination marks the first time the Iowa Lottery’s investigative files have been audited by an outside authority. It also appears to be the first full-scale investigation of its kind in the United States.

Neurally adjusted ventilatory assist can improve arterial oxygenation

INTRODUCTION. Neurally Adjusted Ventilatory Assist (NAVA) [1] is a new spontaneousassisted ventilatory mode which uses the diaphragmatic electrical activity (Eadi) to pilot the ventilator. Eadi is used to initiate the ventilator's pressurization and cycling off. Delivered inspiratory assistance is proportional to Eadi. NAVA can improve patient-ventilator synchrony [2] compared to pressure support (PS), but little is known about its effect on minute ventilation and oxygenation. OBJECTIVES. To compare the effects of NAVA and PS on minute ventilation and oxygenation and to analyze potential determinant factors for oxygenation. METHODS. Comparison between two 20-min periods under NAVA and PS. NAVA gain (proportionality factor between Eadi and delivered pressure) set as to obtain the same peak pressure as in PS. FIO2 and positive end-expiratory pressure (PEEP) were the same in NAVA and PS. Blood gas analyses were performed at the end of both recording periods. Statistical analysis: groups were compared with paired t tests or non parametric Wilcoxon signed-rank tests. p\0.05 was considered significant. RESULTS. [Mean ± SD]: 22 patients (age 66 ± 12 year, 7 M/15F, BMI 23.4 ± 3.1 kg/m2), 8 patients with COPD. Initial settings: PS 13 ± 3 cmH2O, PEEP 7 ± 2 cmH2O, NAVA gain 2.2 ± 1.8. Minute ventilation and PaCO2 were the same with both modes (p = 0.296 and 0.848, respectively). Tidal volume was lower with NAVA (427 ± 102 vs. 477 ± 102 ml, p\0.001). In contrast respiratory rate was higher with NAVA (25.6 ± 9.5 vs. 22.3 ± 8.9 cycles/min). Arterial oxygenation was improved with NAVA (PaO2 85.1 ± 28.9 vs. 75.8 ± 11.9 mmHg, p = 0.017, PaO2/FIO2 210 ± 53 vs. 195 ± 58 mmHg, p = 0.019). Neural inspiratory time (Tin) was comparable between NAVA and PS (p = 0.566). Among potential determinant factors for oxygenation, mean airway pressure (Pmean) was lower with NAVA (10.6 ± 2.6 vs. 11.1 ± 2.4 cmH2O, p = 0.006), as was the pressure time product (PTP) (6.8 ± 3.0 vs. 9.2 ± 3.5 cmH2O 9 s, p = 0.004). There were less asynchrony events with NAVA (2.3 ± 2.0 vs. 4.4 ± 3.8, p = 0.009).Tidal volume variability was higher with NAVA (variation coefficient: 30 ± 19.5 vs. 13.5 ± 8.6, p\0.001). Inspiratory time in excess (Tiex) was lower with NAVA (56 ± 23 vs. 202 ± 200 ms, p = 0.001). CONCLUSION. Despite lower Pmean and PTP in NAVA, arterial oxygenation was improved compared to PS. As asynchronies may be associated with an increased work of breathing and a higher oxygen consumption, their decrease in number with NAVA could be an explanation for oxygenation improvement. Another explanation could be the increase in VT variability. Further studies should now be performed to confirm the potential of NAVA in improving arterial oxygenation and explore the underlying mechanisms.
