An integration of Euler's pentagonal partition
Giuseppe Scollo
Computer Science , 2010,
Abstract: A recurrent formula is presented, for the enumeration of the compositions of positive integers as sums over multisets of positive integers, that closely resembles Euler's recurrence based on the pentagonal numbers, but where the coefficients result from a discrete integration of Euler's coefficients. Both a bijective proof and one based on generating functions show the equivalence of the subject recurrences.

Abstract:

The aim of this study is to compare morbidity, surgical treatment and post-operative complications in elderly patients underwent surgery for advanced stage ovarian cancer, comparing to younger patients. Data of patients underwent surgery at the Department of Obstetrics and Gynecology of Cannizzaro Hospital (Catania) for advanced stage (IIIC-IV) ovarian cancer were collected from January 2000 to December 2013. Patients were stratified by age in two groups (I > 65 years and II < 65 years old). Following variables were collected: stage of the tumor, associated diseases, previous chemotherapy, the type of surgical procedures, blood transfusions, intraoperative and postoperative morbidity, mortality, and hospital stay. Median values between the two groups were compared using Mann-Whitney test and frequency data usingχ2. Statistical significance was defined as P < 0.05. A total of 179 patients were identified, they were divided into 2 groups: 64 patients were age 65 years or older (group I) and 115 patients were younger than age 65 (group II). In the whole series, 157 patients (87%) did not experience any complication. Overall, postoperative complications occurred in 10 (15%) patients in the group I and in 12 (10%) in the group II (p =NS). In conclusion, elderly patients may tolerate well surgical procedures within acceptable postoperative morbidity, a length of hospital stay and a need for intensive care quite similar to that of younger patients.

Abstract: in the neonates born to t. cruzi infected mothers, the diagnosis of the congenital transmission relays on the detection of the parasites and/or the specific antibodies non-transferred by their mothers, in the absence of blood transfusion and vectorial transmission. in the early stage, approximately until the 7th month of life, when maternal immunoglobulins could be present, the diagnosis depends on the detection of the parasite. then, in the late stage, from the 8th month, the detection of specific antibodies by at least 2 of 3 serological tests confirms the infection in the neonates. the diagnostic follow up of the children born to a group of sero-reactive pregnant women was carried out in the inp. the 11% of the mothers (29 out of 267) transmitted the infection to their children. the neonates of 20 of these mothers were diagnosed in the early stage, 14 and 6 in one or two controls, respectively. in the 9 remaining mothers the children were diagnosed in the late stage of the infection, mainly serologicaly. our analisis of previously published reports stressed that the maternal-fetal transmission rate depends on the time of diagnostic follow up of the child. in this reports, mean values of mother to child transmission reported was 2% and 9% when the diagnosis of the neonates born to sero-reactive mothers was carried out only in the early stage or in the early and also the late stage, respectively.

Abstract: in order to estimate the frequence of candida dubliniensis in clinical samples in f. j. mu?iz infectious diseases hospital, a total of 388 yeasts from september 2005 to august 2007. there were 212 isolates which presented a green color on chromagar? candida medium and produced germ tubes and chlamidoconidiae in milk-agar; so as to distinguish whether they corresponded to candida albicans or c. dubliniensis, different phenotypical methods were utilized. it was also evaluated the usefulness of each one in order to suggest a simple, economic and reliable identification algorithm. each isolate was subcultured in two chromogenic media and then, the following determinations were done: chlamidospores production in staib-agar, tomato-carrot-agar and tobacco-agar, colonies macromorphology was also studied in the last medium; opacity-test in tween 80-cacl2 agar (lipase activity), growing capacity at 45 °c, and d-xylose assimilation. thirteen strains (6.1%) corresponded to c. dubliniensis. the difference in color between both species on chromogenic media was not so stressed as it is pointed out in some works. the more specific and sensitive tests were the ability to grow at 45 °c, d-xylose assimilation, color and macroscopic appearance in tobacco-agar. between 11.6% and 15.1% of c. albicans strains produced chlamidoconidiae in the 3 differential media tested. the opacity halo (lipase) was evident in 95.6% of c. albicans isolates but 2 out of 13 c. dubliniensis also presented precipitation halo. we consider that at least 3 different phenotypical methods should be used to distinguish properly these two species since none of the tests is absolutely sensitive or specific.

Abstract: El diagnóstico de la transmisión congénita del T. cruzi en hijos de mujeres infectadas se realiza por detección de la parasitemia y/o de anticuerpos específicos no transferidos por la madre, en ausencia de transfusión sanguínea y transmisión vectorial. En la etapa temprana, aproximadamente hasta el 7° mes de vida, cuando es posible la presencia de inmunoglobulinas maternas, el diagnóstico depende de la detección del parásito. Luego, en la etapa tardía, a partir del 8° mes de vida, la detección de anticuerpos específicos con por lo menos 2 de 3 pruebas serológicas permiten el diagnóstico del ni o. En el INP hemos realizado el seguimiento de los ni os de un grupo de mujeres embarazadas sero-reactivas que concurrieron para el diagnóstico de la infección. El 11% de ellas (29 de 267) transmitieron la infección a sus ni os. Los hijos de 20 de estas mujeres fueron diagnosticados en la etapa temprana, con 1 o 2 controles parasitológicos, en 14 y 6 casos respectivamente. En las 9 madres restantes los ni os fueron diagnosticados principalmente por la serología en la etapa tardía de la infección. Nuestro análisis de los datos publicados anteriormente enfatizan que el porcentaje de la transmisión madre-hijo depende principalmente del tiempo de seguimiento diagnóstico del ni o. En estos trabajos, cuando el diagnóstico del ni o se realizó sólo en la etapa temprana se notificó aproximadamente un 2% de transmisión materno-fetal, mientras que cuando también se estudiaron a los ni os en la etapa tardía se encontró un promedio de 9% de casos de transmisión congénita. In the neonates born to T. cruzi infected mothers, the diagnosis of the congenital transmission relays on the detection of the parasites and/or the specific antibodies non-transferred by their mothers, in the absence of blood transfusion and vectorial transmission. In the early stage, approximately until the 7th month of life, when maternal immunoglobulins could be present, the diagnosis depends on the detection of the parasite. Then, in the late stage, from the 8th month, the detection of specific antibodies by at least 2 of 3 serological tests confirms the infection in the neonates.

Abstract: With the perspective to test drugs that may reduce pain due to surgical castration, this preliminary study tries to find out a robust and valid method for pain assessment in piglets. In the present study three treatments were applied: handling (H), tail docking (TD) and surgical castration + tail docking (CTD). To evaluate pain response to the treatments different variables were analyzed: movement latency (time from placing back the piglet inside the farrowing crate after treatments and its first movement towards the nest or the sow), rectal temperature and plasma cortisol and lactate levels.Movement latency was measured for all treatments. Rectal temperature was measured before treatments H and CTD, and 1, 3, 5, 24 hours later. Blood samples for cortisol and lactate determination were collected 1 hour before treatments H and CTD, right after and 3, 5, 24 hours later. The significant increase of movement latency for CTD compared to H showed that pain can be assessed by this type of measure. Rectal temperature was significantly affected by time (P < 0.01) but not by treatment likely due to several factors that might have confounded the studied effect. Cortisol was significantly affected by interaction time*treatment (P < 0.01) particularly due to the high peak for CTD right after the surgical procedure. Lactate was modified only by time (P < 0.01). This preliminary study suggests that a non invasive and easy measure such as movement latency is a promising method to assess pain in piglets after surgical castration and tail docking.

Abstract: Con el objeto de estimar la frecuencia de aislamientos de Candida dubliniensis en materiales clínicos en el Hospital de Infecciosas F. J. Mu iz, se identificaron 388 levaduras entre setiembre de 2005 y agosto de 2007. Doscientos doce aislamientos presentaban color verde en CHROMagar y producían tubos germinativos y clamidoconidias en agarleche. Para diferenciar cuales de ellos correspondían a Candida albicans o a C. dubliniensis, se utilizaron distintos métodos fenotípicos y se evaluó la utilidad de cada técnica a fin de proponer un algoritmo de identificación simple, económico y confiable. Se estudió el color en 2 medios con sustratos cromogénicos, la producción de clamidoconidias en medios de Staib, agar tomate-zanahoria y agar-tabaco; en este último medio también se evaluaron las características macromorfológicas de las colonias; se evaluó la presencia de actividad lipolítica (medio-opacidad), capacidad de desarrollo a 45 °C y asimilación de D-xilosa. El 6,1% (13/212 aislamientos) correspondió a C. dubliniensis (3,3% del total de levaduras). No se pudo diferenciar entre ambas especies por el color en los medios cromogénicos usados. Las pruebas que resultaron más sensibles y específicas fueron crecimiento a 45 °C, asimilación de D-xilosa, color y desarrollo en agar-tabaco. C. albicans produjo clamidoconidias en los 3 medios diferenciales, entre 11,6% y 15,1% de los casos. La presencia de lipasas se evidenció en el 95,6% de C. albicans pero 2 de las 13 cepas de C. dubliniensis también presentaron halo de opacidad. Consideramos que se deben usar, al menos, 3 métodos diferentes para discriminar entre estas levaduras ya que ninguna prueba es absolutamente sensible o específica.

Abstract: Introducción: El topinambur es un tubérculo con alto contenido en inulina. La inulina es un carbohidrato soluble no digerible que está presente en muchos vegetales, frutas y cereales siendo usada ampliamente como ingrediente en alimentos funcionales. Objetivo: Obtener tubérculos de topinambur, fijar distintos parámetros de extracción de inulina y preparar diversos alimentos, reemplazando parte de las harinas tradicionales por harina de topinambur. Se propuso, además, evaluar la preferencia de los consumidores sobre los mismos. Material y métodos: Se sembraron y cosecharon tubérculos de topinambur partiendo de 4 parcelas con diferentes condiciones de riego y fertilización. Los mismos se conservaron a variadas temperaturas. Se determinó el contenido de inulina por HPLC y se realizó la extracción de la misma de los tubérculos. A partir de los tubérculos cosechados en la parcela 3 se elaboraron harinas que fueron utilizadas para reemplazar parcialmente a la harina de trigo en la preparación de diferentes productos alimenticios. Sobre los mismos se realizó una evaluación de preferencia. Resultados: El rinde de la cosecha fue mayor en la parcela 3 (tierra fértil y riego según necesidades), 91 ton/Ha. El método de conservación más adecuado fue el frío, sin embargo no se utilizaron estos tubérculos para la extracción de inulina. Los productos alimenticios obtenidos fueron considerados adecuados por los jueces intervinientes. Conclusiones: la elaboración de productos alimenticios a partir de harina de topinambur podría ser una alternativa de alimento funcional por su contenido de inulina. Introduction: The Jerusalem artichoke Is a tuber high in inulin. Inulin is a soluble non-digestible carbohydrate that is present in many vegetables, fruits and cereals and is widely used as an ingredient in functional foods. Objective: To get Jerusalem artichoke tubers, set various parameters for extraction of inulin and prepare various foods, replacing part of the traditional flour by Jerusalem artichoke flour. The objective was also to assess consumer preference over them. Material and methods: We planted and harvested four plots with Jerusalem artichoke tubers, all with different conditions of irrigation and fertilization. They were stored at various temperatures. Inulin content was determined by HPLC and extracted from the tubers. From the tubers harvested in plot 3 we prepared flours that were used to partially replace wheat flour in the preparation of different food products, on which an evaluation of preference was carried out. Results: The crop yield was higher in plot

Abstract: Annual COPD death rates in Australia from 1922 to 2005 for age groups (50-54, 55-59, 60-64, 65-69, 70-74, 75-79, 80-84, 85+) were used. Functional time series models of age-specific COPD mortality rates for men and women were used, and forecasts of mortality rates were modelled separately for men and women.Functional time series models with four basis functions were fitted to each population separately. Twenty-year forecasts were computed, and indicated an overall decline. This decline may be slower for women than for men. By age, we expect similar rates of decline in men over time. In contrast, for women, forecasts for the age group 75-79 years suggest less of a decline over time compared to younger age groups.By using a new method to predict age-specific trends in COPD mortality over time, this study provides important insights into at-risk age groups for men and women separately, which has implications for policy and program development.Chronic Obstructive Pulmonary Disease (COPD), including chronic bronchitis and emphysema, is currently the fifth leading cause of death in Australia. It was responsible for 31.2 male and 16.3 female deaths per 100,000 population (age-standardized) in 2005 [1].The major known risk factor is tobacco smoking. However, there is a substantial latent period after the uptake of regular smoking, so that COPD typically only becomes manifest decades later. COPD is the only major condition for which the burden of disease (as measured at the population level) is continuing to increase with an ageing population, which is at a higher risk of developing COPD [2]. This is because COPD results in a progressive respiratory disability, a substantial impairment in the quality of life and frequent hospital admissions. COPD is also accompanied by substantial comorbidities, including depression, heart disease and osteoporosis. Yearly mortality time trends which are collected by the Australian Bureau of Statistics provide a sound basis for modelling the
