Adoção do milho transgênico no Estado de São Paulo: resultados econômicos e de riscos

One of the arguments for the rapid adoption of genetically modified (GM0 corn in Brazil is the economic advantage that this technology can offer. Given that its benefits and gains are subject to the conditions of modifications of critical variables, the present work aimed to estimate the economic returns of Bt (Bacillus thuringiensis) corn by analyzing variations in quantities and prices of insecticides used, productivity gains, the price of using GM seed compared with non-GM seed, as well as changes in corn prices. It was concluded that the GM technology generated net economic gains of US$ 235.50/ha.

The Effect of Adenoidectomy or Adenotonsillectomy on Occlusal Features in Mouth-breathing Preschoolers

Purpose: The purpose of this study was to evaluate mouth-breathing and nasal-breathing children prior to surgical intervention and 28 months postoperatively, comparing the occlusal features obtained pre- and postoperatively through orthodontic study costs. Methods: The mouth-breathing (MB) group consists of 33 MB children who underwent surgery and presented a nasal-breathing (NB) pattern after surgery The control group comprised 22 NB children. The orthodontic examinations were accomplished prior to surgery (77) and an average of 28 months postoperatively (T2). Results: At T1, the MB and NB children presented no statistically significant difference in any analyzed occlusal features and measurements. At T2, the MB presented larger overjet comparing to NB children (P<.05). MB and NB groups presented statistically similar results (P>.05) concerning intercanine and intermolor distances, second primary molar terminal plane and canine relationship, overbite, crossbite, and open bite. From T1 to T2, the MB and NB groups showed a statistically significant difference in the molar terminal plane. Conclusion: Neither the breathing pattern nor the surgery had any effect on occlusal features in 3- to 6-year-olds.

Removal of Pb2+ from aqueous solutions using two Brazilian rocks containing zeolites

The removal of Pb2+ from aqueous solution by two Brazilian rocks that contain zeolites-amygdaloidal dacite (ZD) and sandstone (ZS)-was examined by batch experiments. ZD contains mordenite and ZS, stilbite. The effects of contact time, concentration of metal in solution and capacity of Na+ to recover the adsorbed metals were evaluated at room temperature (20A degrees C). The sorption equilibrium was reached in the 30 min of agitation time. Both materials removed 100% of Pb2+ from solutions at concentrations up to 50 mg/L, and at concentrations larger than 100 mg/L of Pb2+, the adsorption capacity of sandstone was more efficient than that of amygdaloidal dacite due to the larger quantities and the type of zeolites (stilbite) in the cement of this rock. All adsorbed Pb2+ was easily replaced by Na+ in both samples. The analysis of the adsorption models using nonlinear regression revealed that the Sips and the Freundlich isotherms provided the best fit for the ZS and ZD experimental data, respectively, indicating the heterogeneous adsorption surfaces of these zeolites.

Rapid sample preparation procedure for As speciation in food samples by LC-ICP-MS

This paper describes a rapid method for arsenic (As) speciation by LC-ICP-MS in several types of food samples. Prior to analysis, samples were milled and the As species extracted from biological tissues by sonication in only 2 min with a solution containing MeOH (10%, v/v) plus HNO3 (2%, v/v). As species were separated by LC using an anion exchange column. Method detection limits for AsB, As3+,DMA, MMA and As5+ were 1.3, 0.9, 0.6, 0.7 and 0.8 ng g(-1), respectively. Method accuracy and precision were traceable to Certified Reference Materials SRM1577 bovine liver from the National Institute of Standards and Technology, CE278 mussel tissue from the Institute of Reference Materials and Measurements and DOLT-3 dogfish liver tissue and DORM-3 fish protein from the National Research Council of Canada. Finally, the method was applied to speciate As in food samples (egg, fish muscle, beef and chicken) purchased in Brazilian markets.

Infiltration of a mixture of immune cells may be related to good prognosis in patients with differentiated thyroid carcinoma

Objective Immune responses against differentiated thyroid carcinomas (DTC) have long been recognized. We aimed to investigate the role of immune cell infiltration in the progression of DTC. Design We studied 398 patients 253 with papillary and 13 with follicular thyroid cancers, as well as 132 with nonmalignant tissues. Patients and measurements Immune cell infiltration was identified using CD3, CD4, CD8, CD20, CD68 and FoxP3 immunohistochemical markers. In addition, we assessed colocalization of CD4 and IL-17 to identify Th17 lymphocytic infiltration and colocalization of CD33 and CD11b to identify infiltration of myeloid-derived suppressor cells (MDSC). Results Immune cells infiltrated malignant tissues more often than benign lesions. The presence of chronic lymphocytic thyroiditis (CLT) concurrent to DTC, CD68+, CD4+, CD8+, CD20+, FoxP3+ and Th17 lymphocytes but not MDSCs was associated with clinical and pathological features of lower tumour aggressiveness and a more favourable patient outcome. A log-rank test confirmed an association between concurrent CLT, tumour-associated macrophage infiltration, and CD8+ lymphocytes and an increased in disease-free survival, suggesting that evidence of these immune reactions is associated with a favourable prognosis. Conclusion Our data suggest that the tumour or peri-tumoural microenvironment may act to modify the observed pattern of immune response. Immune cell infiltration and the presence of concurrent CLT helped characterize specific tumour histotypes associated with favourable prognostic features.

Vertical growth control during maxillary expansion using a bonded Hyrax appliance

INTRODUCTION: Rapid maxillary expansion (RME) for the treatment of maxillary deficiency and posterior crossbite may induce changes in the vertical dimension. Expanders with occlusal splints have been developed to minimize unwanted vertical effects. OBJECTIVE: This preliminary study used cephalometri radiographs to evaluate the vertical effects of RME using a Hyrax appliance in children with maxillary deficiency. METHOD: Twenty-six patients (11 boys; mean age = 8 years and 5 months) with maxillary deficiency and posterior crossbite were treated using a Hyrax appliance with an acrylic occlusal splint. Radiographs and cephalometric studies were performed before the beginning of the treatment (T1) and after RME active time (T2), at a mean interval of 7 months. Results were compared with normative values. RESULTS AND CONCLUSIONS: At the end of treatment, there were no statistically significant changes, and measurements were similar to the normative values. Data showed that there were no significant effects on vertical growth, which suggests that appliances with occlusal splints may be used to correct transverse deficiencies regardless of the patient's growth pattern.

Dose-dependent effect of a single GnRHa injection on the spawning of meagre ("Argyrosomus regius") broodstock reared in captivity

[EN]The present study aimed to determine the spawning efficacy, egg quality and quantity of captive breed meagre induced with a single gonadotrophin-releasing hormone agonist (GnRHa) injection of 0, 1, 5, 10, 15, 20, 25, 30, 40 or 50 μg kg–1 to determine a recommended optimum dose to induce spawning. The doses 10, 15 and 20 μg kg–1 gave eggs with the highest quality (measured as: percentage of viability, floating, fertilisation and hatch) and quantity (measured as: total number of eggs, number of viable eggs, number of floating eggs, number of hatched larvae and number of larvae that reabsorbed the yolk sac). All egg quantity parameters were described by Gaussian regression analysis with R2 = 0.89 or R2 = 0.88. The Gaussian regression analysis identified that the optimal dose used was 15 μg kg–1. The regression analysis highlighted that this comprehensive study examined doses that ranged from low doses insufficient to stimulate a high spawning response (significantly lower egg quantities, p < 0.05) compared to 15 μg kg–1 through to high doses that stimulated the spawning of significantly lower egg quantities and eggs with significantly lower quality (egg viability). In addition, the latency period (time from hormone application to spawning) decreased with increasing doses to give a regression (R2 = 0.93), which suggests that higher doses accelerated oocyte development that in turn reduced egg quality and quantity. The identification of an optimal dose for the spawning of meagre, which has high aquaculture potential, represents an important advance for the Mediterranean aquaculture industry.

The performance of recently developed pH optodes will als

Indagine delle proprietà statistiche di serie temporali di posizione applicata al caso della stazione permanente GPS della base Mario Zucchelli in Terra Vittoria (Antartide)

Da ormai sette anni la stazione permanente GPS di Baia Terranova acquisisce dati giornalieri che opportunamente elaborati consentono di contribuire alla comprensione della dinamica antartica e a verificare se modelli globali di natura geofisica siano aderenti all’area di interesse della stazione GPS permanente. Da ricerche bibliografiche condotte si è dedotto che una serie GPS presenta molteplici possibili perturbazioni principalmente dovute a errori nella modellizzazione di alcuni dati ancillari necessari al processamento. Non solo, da alcune analisi svolte, è emerso come tali serie temporali ricavate da rilievi geodetici, siano afflitte da differenti tipologie di rumore che possono alterare, se non opportunamente considerate, i parametri di interesse per le interpretazioni geofisiche del dato. Il lavoro di tesi consiste nel comprendere in che misura tali errori, possano incidere sui parametri dinamici che caratterizzano il moto della stazione permanente, facendo particolare riferimento alla velocità del punto sul quale la stazione è installata e sugli eventuali segnali periodici che possono essere individuati.

Effetti degli accordi Euro-Mediterrani sul comparto dell'ortofrutta fresca

In 1995, the European Union (EU) Member States and 12 Mediterranean countries launched in Barcelona a liberalization process that aims at establishing a free trade area (to be realized by 2010) and at promoting a sustainable and balanced economic development by the adoption of a new generation of Agreements: the Euro-Mediterranean Agreements (EMA). For the Mediterranean partner countries, the main concern is a better access for their fruit and vegetable exports to the European market. These products represent the main exports of these countries, and the EU is their first trading partner. On the other side, for the EU the main issue is not only the promotion of its products, but also the protection of its fruit and vegetables producers. Moreover, the trade with third countries is the key element of the Common Market Organization of the sector. Fruit and vegetables represent a very sensitive sector since their high seasonality, high perishability, and especially since the production of the Mediterranean countries is often similar to the European Mediterranean’s countries one. In fact, the agreements define preferences at the entrance of the EU market providing limited concessions for each partner, for specific products, limited quantities and calendars. This research tries to analyze the bilateral trade volume for fresh fruit and vegetables in the European and Italian markets in order to assess the effects of Mediterranean liberalization on this sector. Free trade of agricultural products represents a very actual topic in international trade and the Mediterranean countries, recognised as big producers of fruit and vegetables, as big exporters of their crops and actually significantly present on the European market, could be high competitors with the inward production because the outlet could be the same. The goal of this study is to provide some considerations about the competitiveness of mediterranean fruit and vegetables productions after Barcelona Process, in a first step for the European market and then also for the Italian one. The aim is to discuss the influence of the euro-mediterranean agreements on the fruit and vegetables trade between 10 foreign Mediterranean countries (Algeria, Egypt, Israel, Jordan, Libya, Lebanon, Morocco, Tunisia, Syria, and Turkey) and 15 EU countries in the period 1995-2007, by means of a gravity model, which is a widespread methodology in international trade analysis. The basic idea of gravity models is that bilateral trade from one country to another (as the dependent variable) can be explained by a set of factors: - factors that capture the potential of a country to export goods and services; - factors that capture the propensity of a country to imports goods and services; - any other forces that either attract or inhibit bilateral trade. This analysis compares only imports’ flows by Europe and by Italy (in volumes) from Mediterranean countries, since the exports’ flows toward those foreign countries are not significant, especially for Italy. The market of fruit and vegetables appears as a high heterogeneous group so it is very difficult to show a synthesis of the analysis performed and the related results. In fact, this sector includes the so called “poor products” (such as potatoes and legumes), and the “rich product”, such as nuts or exotic fruit, and there are a lot of different goods that arouse a dissimilar consumer demand which directly influence the import requirements. Fruit and vegetables sector includes products with extremely different biological cycles, leading to a very unlike seasonality. Moreover, the Mediterranean area appears as a highly heterogeneous bloc, including countries which differ from the others for economic size, production potential, capability to export and for the relationships with the EU. The econometric estimation includes 68 analyses, 34 of which considering the European import and 34 the Italian import and the products are examined in their aggregated form and in their disaggregated level. The analysis obtains a very high R2 coefficient, which means that the methodology is able to assess the import effects on fruit and vegetables associated to the Association Agreements, preferential tariffs, regional integration, and others information involved in the equation. The empirical analysis suggests that fruits and vegetables trade flows are well explained by some parameters: size of the involved countries (especially GDP and population of the Mediterranean countries); distances; prices of imported products; local production for the aggregated products; preferential expressed tariffs like duty free; sub-regional agreements that enforce the export capability. The euro-mediterranean agreements are significant in some of the performed analysis, confirming the slow and gradual evolution of euro- Mediterranean liberalization. The euro-mediterranean liberalization provides opportunities from one side, and imposes a new important challenge from the other side. For the EU the chance is that fruit and vegetables imported from the mediterranean area represent a support for local supply and a possibility to increase the range of products existing on the market. The challenge regards the competition of foreign products with the local ones since the types of productions are similar and markets coincide, especially in the Italian issue. We need to apply a strategy based not on a trade antagonism, but on the realization of a common plane market with the Mediterranean countries. This goal could be achieved enhancing the industrial cooperation in addition to commercial relationships, and increasing investments’ flows in the Mediterranean countries aiming at transforming those countries from potential competitors to trade partners and creating new commercial policies to export towards extra European countries.

Spin polarised Heusler compounds

In der vorliegenden Dissertation dient ein einfaches Konzept zur Systematisierung der Suche nach neuen Materialien mit hoher Spinpolarisation. Dieses Konzept basiert auf zwei semi-empirischen Modellen. Zum einen kann die Slater-Pauling Regel zur Abschätzung magnetischer Momente verwendet werden. Dieses Modell wird dabei durch Rechnungen zur elektronischen Struktur unterstützt. Das zweites Modell kann insbesondere für die Co2YZ Heusler Verbindungen beim Vergleich ihrer magnetischen Eigenschaften gefunden werden. Für diese Verbindungen ergibt sich eine scheinbare lineare Abhängigkeit der Curie-Temperatur beim Auftragen als Funktion des magnetischen Momentes. Angeregt durch diese Modelle wurde die Heusler Verbindung Co2FeSi nochmals detailliert im Hinblick auf ihre geometrische und magnetische Struktur hin untersucht. Als Methoden dienten dabei die Pulver-Röntgenbeugung, die EXAFS Spektroskopie, Röntgen Absorptions- and Mößbauer Spektroskopie sowie Hoch- und Tieftemperatur Magnetometrie, XMCD and DSC. Die Messungen zeigten, dass es sich bei Co2FeSi um das Material mit dem höchsten magnetischen Moment (6 B) und der höchsten Curie Temperatur (1100 K) sowohl in der Klasse der Heusler Verbindungen als auch in der Klasse der halbmetallischen Ferromagnete handelt. Zusätzlich werden alle experimentellen Ergebnisse durch detaillierte Rechnungen zur elektronischen Struktur unterstützt. Die gleichen Konzepte wurden verwendet, um die Eigenschaften der Heusler Verbindung Co2Cr1-xFexAl vorherzusagen. Die elektronische Struktur und die spektroskopischen Eigenschaften wurden mit der voll-relativistischen Korringa-Kohn-Rostocker Methode berechnet, unter Verwendung kohärenter Potentialnäherungen um der zufälligen Verteilung von Cr und Fe Atomen sowie zufälliger Unordnung Rechnung zu tragen. Magnetische Effekte wurden durch die Verwendung Spin-abhängiger Potentiale im Rahmen der lokalen Spin-Dichte-Näherung mit eingeschlossen. Die strukturellen und chemischen Eigenschaften der quaternären Heusler Verbindung Co2Cr1-xFexAl wurden an Pulver und Bulkproben gemessen. Die Fernordnung wurde mit der Pulver Röntgenbeugung und Neutronenbeugung untersucht, während die Nahordnung mit der EXAFS Spektroskopie aufgeklärt wurde. Die magnetische Struktur von Pulver und Bulkproben wurde mitttels 57Fe-Mößbauer Spektroskopie gemessen. Die chemische Zusammensetzung wurde durch XPS analysiert. Die Ergebnisse dieser Methoden wurden verglichen, um eine Einsicht in die Unterschiede zwischen Oberflächen und Volumeneigenschaften zu erlangen sowie in das Auftreten von Fehlordnung in solchen Verbindungen. Zusätzlich wurde XMCD an den L3,2 Kanten von Co, Fe, and Cr gemessen, um die elementspezifischen magnetischen Momente zu bestimmen. Rechnungen und Messungen zeigen dabei eine Zunahme des magnetischen Momentes bei steigendem Fe-Anteil. Resonante Photoemission mit weicher Röntgenstrahlung sowie Hochenergie Photoemission mit harter Röntgenstrahlung wurden verwendet, um die Zustandsdichte der besetzten Zustände in Co2Cr0.6Fe0.4Al zu untersuchen. Diese Arbeit stellt außerdem eine weitere, neue Verbindung aus der Klasse der Heusler Verbindungen vor. Co2CrIn ist L21 geordnet, wie Messungen mittels Pulver Röntgenbeugung zeigen. Die magnetischen Eigenschaften wurden mit magnetometrisch bestimmt. Co2CrIn ist weichmagnetisch mit einer Sättigungsmagnetisierung von 1.2B bei 5 K. Im Gegensatz zu den bereits oben erwähnten Co2YZ Heusler Verbindungen ist Co2CrIn kein halbmetallischer Ferromagnet. Im Rahmen dieser Arbeit wird weiterhin eine Regel zur Vorhersage von halbmetallischen komplett kompensierten Ferrimagneten in der Klasse der Heusler Verbindungen vorgestellt. Dieses Konzept resultiert aus der Kombination der Slater-Pauling Regel mit der Kübler-Regel. Die Kübler Regel besagt, dass Mn auf der Y Position zu einem hoch lokalisierten magnetischen Moment tendiert. Unter Verwendung dieses neuen Konzeptes werden für einige Kandidaten in der Klasse der Heusler Verbindungen die Eigenschaft des halbmetallischen komplett kompensierten Ferrimagnetismus vorhergesagt. Die Anwendung dieses Konzeptes wird anhand von Rechnungen zur elektronischen Struktur bestätigt.

Optimierung der Pharmakotherapie schizophrener Patienten durch objektive Symptomerfassung und Therapeutisches Drug Monitoring

Der Erfolg einer Schizophrenie-Behandlung ist zum größten Teil abhängig vom Ansprechen des Patienten auf seine antipsychotische Medikation. Welches Medikament und welche Dosis bei einem individuellen Patienten wirksam sind, kann derzeit erst nach mehrwöchiger Behandlung beurteilt werden. Ein Grund für variierendes Therapieansprechen sind variable Plasmakonzentrationen der Antipsychotika. Ziel dieser Arbeit war es, zu untersuchen, in wieweit der Therapieerfolg zu einem frühen Zeitpunkt der Behandlung durch objektive Symptomerfassung vorhersagbar ist und welche Faktoren die hohe Variabilität der Antipsychotikaspiegel im Blut beeinflussen. rnEine 18-monatige naturalistische klinische Studie an schizophrenen Patienten wurde durchgeführt, um folgende Fragen zu beantworten: Kann man das Therapieansprechen prädizieren und welche Instrumente sind dafür geeignet? Die Psychopathologie wurde anhand zweier Messskalen (Brief Psychiatric Rating Scale, BPRS und Clinical Global Impressions, CGI) wöchentlich ermittelt, um die Besserung der Krankheitssymptome im Verlauf von 8 Wochen zu bewerten. Therapiebegleitend wurden noch die Serum-Konzentrationen der Antipsychotika gemessen. Objektive Symptomerfassung durch BPRS oder CGI waren als Messinstrumente geeignet, Therapieansprechen vorherzusagen. Bezogen auf den Behandlungsbeginn war eine Verminderung der Symptome hoch prädiktiv für späteres Therapieversagen oder -ansprechen. Eine Verminderung um mehr als 36,5% auf der BPRS Skala in Woche 2 wurde als signifikanter Schwellenwert für Nichtansprechen ermittelt. Patienten, deren Symptombesserung unterhalb des Schwellenwertes lag, hatten eine 11,2-fach höhere Wahrscheinlichkeit, am Ende der Studie nicht auf ihre medikamentöse Therapie anzusprechen als die Patienten, die sich um mindestens 36,5% verbesserten. Andere Faktoren, wie Alter, Geschlecht, Dauer der Erkrankung oder Anzahl der stationären Aufenthalte hatten keinen Einfluss auf die Prädiktion des Therapieansprechens. Therapeutische Antipsychotika-Spiegel übten einen positiven Einfluss auf die Ansprechrate aus. Bei Patienten mit therapeutischen Spiegeln war das Ansprechen rascher und die Ansprechrate größer als unter denjenigen deren Spiegel außerhalb der therapeutisch üblichen Bereiche lag. rnEine wichtige Voraussetzung für den Einsatz von TDM ist das Vorhandensein einer präzisen, reproduzierbaren, zeit- und kostensparenden analytischen Methode zur quantitativen Bestimmung der untersuchten Substanzen. Die Entwicklung und Validierung einer solchen geeigneten Methode wurde für den Nachweis von Haloperidol vorgenommen. Eine HPLC-Methode mit Säulenschaltung erwies sich für TDM geeignet. rnBasierend auf den Ergebnissen der eigenen klinischen Studie zur Response Prädiktion wurde untersucht, welche Faktoren die Variabilität der Pharmakokinetik von Antipsychotika beeinflussen. Die Variabilität der Pharmakokinetik ist ein Grund für fehlendes oder unzureichendes Ansprechen. Es wurde zum einen der Einfluss der galenischen Formulierung auf die Freisetzung und zum anderen der Einfluss von entzündlichen Prozessen auf die Metabolisierung eines Antipsychotikums untersucht. Dazu wurden Patientendaten retrospektiv ausgewertet.rnDie Analyse von 247 Serumspiegeln von Patienten, die mit Paliperidon in OROS®Formulierung, einer neu eingeführten Retardform, behandelt wurden, zeigte, dass die intraindividuelle Variabilität der Talspiegel (Vk) von Paliperidon 35% betrug. Er war damit vergleichbar wie für nicht retardiertes Risperidon 32% (p=n.s.). Die Retardierung hatte demnach keinen Varianz mindernden Effekt auf die Talspiegel des Antipsychotikums. Der Wirkstoff-Konzentrations-Bereich lag bei 21-55 ng/ml und entsprach ebenfalls nahezu dem therapeutischen Bereich von Risperidon (20-60 ng/ml). rnEntzündliche Prozesse können die Metabolisierung von Medikamenten verändern. Dies wurde bisher für Medikamente nachgewiesen, die über CYP1A2 abgebaut werden. Durch die eigene Analyse von 84 Patienten-Serumspiegeln konnte festgestellt werden, dass die Metabolisierung von Quetiapin während eines entzündlichen Prozesses beeinträchtigt war, wahrscheinlich durch Hemmung von CYP3A4. Dies sprach dafür, dass auch Wirkstoffe, die über CYP3A4 abgebaut werden, während eines entzündlichen Prozesses im Körper in ihrer Pharmakokinetik beeinträchtigt sein können. Aus diesem Grund sollte während einer Infektion unter der Therapie mit Quetiapin besonders auf die Nebenwirkungen geachtet werden und der Serumspiegel sollte in dieser Zeit überwacht werden, um den Patienten vor eventuellen Nebenwirkungen oder sogar Intoxikationen zu schützen. rnDie Befunde dieser Arbeit zeigen, dass bei einer Behandlung schizophrener Patienten mit Antipsychotika die Messung der Psychopathologie zur Vorhersage des Therapieansprechens und die Messung der Blutspiegel zur Identifizierung von Faktoren, die die pharmakokinetische Variabilität bedingen, geeignet sind. Objektive Symptomerfassung und Therapeutisches Drug Monitoring sind demnach Instrumente, die für die Steuerung der antipsychotischen Pharmakotherapie genutzt werden sollten.rn
