The Aging Bladder in Females Evaluated by Urodynamics  [PDF]
M. C. de Albuquerque Neto, Leslie Clifford Noronha Araujo, Thome Decio Pinheiro Barros Junior, Joao Luiz Amaro, Flavia Cristina Morone Pinto, Fabio de Oliveira Vilar, Salvador Vilar Correia Lima
Open Journal of Urology (OJU) , 2017, DOI: 10.4236/oju.2017.73008
Abstract: Aim: To determine whether bladder functions deteriorate with age. Methods: Data contained in electronic medical record (INFOMED?) were used in this institutional retrospective review. Analysis was done on the urodynamic studies in women over 18 years old conducted between May 2011 and November 2015. Patients with previous history of pelvic surgery or radiotherapy, neurological disease, vaginal prolapse greater than grade I, congenital urogenital malformations, urinary obstructive disease, diabetes, or the use of any medication that could interfere with bladder function were excluded from the analysis. The urodynamic parameters analyzed were the Maximum Cystometric Capacity (MCC), Voiding Volume (VV), Maximum Flow (Qmax), Bladder Compliance (BC), Detrusor Pressure at Maximum Flow (PdetQmax), Bladder Contractility Index (BCI), Bladder Voiding Efficiency (BVE) and Post-Void Residual Urine Volume (PVR). Patients were further stratified in five groups according to age (A—18 to 40; B—41 to 50; C—51 to 60; D—61 to 70; E—over 70 years old). Results: Out of 3103 urodynamic studies analyzed, 719 were eligible for the study. The average age of patients was 49.3 (+13.2) years old and in all evaluated parameters, statistically significant correlation between age and decline of bladder function was obtained (p < 0.05). Moreover, mathematical equations were presented to estimate the parameters values in relation to age. Conclusions: This study showed a decline in bladder storage function (reduction in MCC and BC) and in bladder emptying function (reduction in Qmax, PdetQmax, VV, BCI and BVE with an increase in PVR) with age.
A New Biomaterial for Urinary Catheters  [PDF]
Roberto Santos Lima, Salvador Vilar Correia Lima, José Lamartine De Andrade Aguiar, Eziel Cavalcanti Vasconcelos Rocha, Flávia Cristina Morone Pinto
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2018, DOI: 10.4236/jbnb.2018.91001
Abstract: Several studies argue that an ideal biomaterial for urinary catheters is utopian. Based in literature review it seems to be true. However, research advances: the biomaterial itself, new designs, new coatings, associated drugs, etc. Once implanted and interacting with urine, two old problems persist: encrustation and bacterial colonization. In this context, an extracellular product from bacterial synthesis on sugarcane molasses biomaterial has been studied in several experimental and clinical studies. Based on its high biocompatibility, the aim of this study is to evaluate its performance in an in vivo model as an endourologic prosthesis implanted in the bladder of Wistar rats. We evaluate physical, chemical and biological phenomena in comparison to an already established biomaterial, polyurethane. Even though it is not a finished product, the sugarcane biopolymer presented similar performance compared to polyurethane in several analyzed parameters and has an important characteristic: low cost.

Abstract: the harvest point is one of the most important factors to minimal processing of guavas. the objective of this research was to determine the ideal maturity stage of 'kumagai' and 'pedro sato' guavas for fresh-cut. both varieties of guavas fruits were harvested in three maturity stages defined by the skin color in green, light-green and yellowish-green. guavas were sanitized, refrigerated, processed in round slices, packed in trays with pvc film and stored at 5±1°c e 80±5% rh. physical-chemical and sensorial analyses took place in the beginning of the experiment and every three days during nine days. guavas in advanced maturity stages showed severe loss of firmness and browning of the pulp, which are characteristics of senescence. however, these treatments had the highest grades for the sensorial analysis of appearance. already, guavas at green maturity stage showed low acceptability grades during evaluations. therefore, the light-green and yellowish-green maturity stages are indicates to the minimal processing of guavas. however, it is necessary to involve technical control of senescence to increase the shelf life of fresh-cut guavas

Abstract: The objective of this study is to analyze the relationship between the structural funds provided by the European Union (EU) and the real convergence of the New Member States that joined the EU in 2004. We also assess the effect of the crisis on this. According to the empirical studies in this area, the impact can be both negative and positive. Furthermore, in the latter case, the correlation is not very strong and depends on several factors. To meet the research objective, we have structured this paper into five parts. In the first part, we make a short presentation of the Cohesion policy and its evolution in time. In the second part, we explore the importance of the subject in the economic literature. In the third one, we explain the methodology used in this paper. We contribute to the literature by creating a Real Convergence Index (RCI) and by assessing the evolution of this index and of the structural funds payments from 2004 until 2010 in five New Member States (Hungary, the Czech Republic, Poland, Slovakia and Slovenia). The fourth part describes the results obtained. The structural funds payments reached a maximum level in 2007 in all the countries, with the exception of Slovenia. After this point, they recorded decreasing levels, mainly because of the economic and financial crisis. Within this group of countries, Poland and Slovakia recorded an increase in RCI during 2009 and 2010, even though the amounts of payments started decreasing. The highest level of structural funds payments and the maximum level of RCI are not synchronized, with the exception of the Czech Republic. This could come as a result of the lagging effects of structural funds on the economic convergence. The fifth part of the paper summarizes the conclusions of our research. The analysis confirms the previous work in this field. Specifically, it does not provide us with a clear result regarding the relationship between the absorption of structural funds and the real convergence. The implications for Romania are not very encouraging. This means that the efforts for increasing the absorption rate of EU funds will not necessarily lead to a faster real convergence process. Consequently, the effectiveness of the Cohesion policy remains under question.

Abstract: The objective of this paper is to examine how the current financial crisis has affected the fiscal discipline and convergence in the seven Central and Eastern European countries which have not yet joined the Euro Area (EA), namely Bulgaria, the Czech Republic, Hungary, Latvia, Lithuania, Poland and Romania. In the first part, we emphasize the importance of fiscal discipline for the effective functioning of the European Monetary Union (EMU). In the second part, by exploring the current status of the literature in this field, we identify scarce theoretical and empirical research on the non-EA countriesa€ fiscal discipline and convergence. In the third one, we briefly present the data and methodology used in the paper. We report the fiscal discipline of the non-EA countries by analysing their distance from the Maastricht criteria regarding the budgetary deficit and the public debt as shares of GDP in the fourth part. We also assess the fiscal convergence of the seven candidates for Euro adoption in order to understand whether they add to the strengths or to the weaknesses of the EMU, from a fiscal point of view, by employing two benchmarks: the EA core and the EA periphery. The sovereign debt crisis emphasized the asymmetry between core and periphery countries. It is of major importance to know if the EA candidates will exacerbate the fiscal imbalances by joining the periphery group of countries or by contrast, will promote fiscal discipline and sustainability alongside the core EA member states. The fifth part concludes. The non-EA group of countries has not experienced major fiscal imbalances in the last four years, but the efforts must continue in reducing the budgetary deficits and controlling the public debts. In times of crisis, the EA candidates achieved more convergence with the EA core than with the EA periphery, by reducing the distance from the EA core. This is due to a deterioration in the fiscal performance of the EA core states and not to an improvement in the non-EA group of countries. The result is not encouraging for the fiscal convergence given the fact that we would expect an improvement in the non-EA countriesa€ fiscal performance in order to catch-up with the best performers of the EA and not the reverse. In terms of public debt, the fiscal convergence with the EA core would not be desirable, due to the high levels of public debt achieved by these countries.
Dental treatment of twin monozygotic brothers with Fragile X syndrome  [PDF]

Health (Health) , 2010, DOI: 10.4236/health.2010.210176
Abstract: Fragile X syndrome (FXS) is the main cause of inherited mental retardation and is the result of transcriptional silencing of the fragile X mental retardation gene FMR1. An absence of the associated protein FMRP leads to the deregulation of many genes, which results in phenotypes of Attention-Deficit Hyperactivity Disorder (ADHD), anxiety, epilepsy and autism. The aim of this article is to report the clinical case of twin siblings affected by FXS and to describe the procedures for dental treatment with intravenous sedation. Information regarding the characteristic manifestations of FXS not only aided in the handling of the patients but also enabled us to develop clinical programs to promote and maintain oral health using individualized and specific dental procedures.

Abstract: Even with rigorous environmental regulations, phenol still is a major contaminant. One possible solution is the use of heterogeneous photocatalysis due to low chemical addition, feasibility and reliability to be implanted on cost-effective industrial process. TiO2 is the most employed photocatalyst because of its favorable (photo) chemical properties and ZnO is considered one of the best alternative for that. Other oxides were tested in lesser proportions, like CuO and Ga2O3. When the photocatalyst is dispersed as slurry, higher degradation rates are achieved due to high solid to liquid contact area when compared with supported form. The aim of this work was to develop a batch recirculating photocatalytic reactor and evaluate its efficiency when assisted by the photocatalysts TiO2 P25, ZnO, CuO and β-Ga2O3. TiO2 achieved 95% mineralization after 200 min reaction in an average degradation rate of 0.68 mg·L﹣1·min﹣1 and ZnO was less efficient (0.41 mg·L﹣1·min﹣1). Ga2O3 and CuO presented poor performance, mainly due to low surface area for the CuO syntesized and the absorption of the UV radiation by the reactor walls, decreasing Ga2O3 activity. Degradation intermediates were detected in diverse concentrations and at different operational times for each oxide tested, which indicate different degradation mechanisms.
Auto-incompatibilidade em Miconia ciliata (L.C.Rich.) DC. (Miconieae - Melastomataceae)
Melo, Gladys Flavia de;Machado, Isabel Cristina;
Acta Botanica Brasilica , 1998, DOI: 10.1590/S0102-33061998000200002
Abstract: miconia ciliata is a shrub whith flowers over a period of 11 months. the flowers are hermaphrodite with diurnal anthesis. probably miconia ciliata exhibits gametophytic incompatibility - pollen tube growth's interrupted in the style. bees of the family halictidae were observed to use the vibration technique to extract pollen (buzz pollination). only few flowers per inflorescence open each day. which probably induces the effective pollinators to visit a larger number of inflorescence in each individual plant, promoting cross pollination. reproductive success in miconia ciliata is favoured by the high frequency of pollinators visits, high p/o ration and high pollen fertility.

Abstract: during the last few decades, contract agriculture constitutes an agricultural integrating and subordinating mechanism to agribusiness expanding in third world countries. in mexico and more precisely in guanajuato, this work routine prevails around the production of cash crops that are frozen for export, uncommon in the cultivation of grains, except for the case of barley and a certain variety of wheat produced for cargill. with grains, another type of contractual relation predominates. the objective of the present article is to analyze the gambit of contractual relations established between producers (cash crops and grains) and agro industry in addition to the implications or impacts they have on both agents. as of the mid 80's, the structural adjustment policy applied in mexico has implied the retirement of the state from the area of production, commercialization and services in the agricultural cattle-producing sector. to this a severe crisis and an increase in the dependency of producers to agribusiness and intermediaries can be added. in this context, contractual relations such as contract agriculture are growing and represent the only survival alternative for an infinite number of grain and cash crop producers.
El maíz amarillo cultivado bajo contrato en México 2000-2005: Reflexiones sobre un programa de comercialización de granos

Cuadernos Geográficos , 2007,
Abstract: Más del 95% del maíz que se produce en México es blanco. En los últimos a os el Estado mexicano ha impulsado la agricultura por contrato de maíz amarillo con la finalidad de contribuir a la sustitución de las más de 5 millones de toneladas que se importan anualmente, volumen necesario para satisfacer la demanda del sector pecuario y de la industria de derivados alimenticios y químicos del maíz. Además busca reconvertir al maíz amarillo un porcentaje de la superficie sembrada con maíz blanco, grano este último que, según datos oficiales, se vería afectado por una sobreproducción estimada de más de 2 millones de toneladas. Los objetivos que se propone este trabajo son conocer las condiciones en que se está dando esta experiencia, valorar qué posibilidad de éxito y expansión tiene la agricultura bajo contrato en el caso del maíz amarillo ante un mercado totalmente abierto a partir del 2008 y explicar los efectos que tiene la producción bajo contrato de este grano en los distintos sujetos participantes.
