Análise da gestão da dívida pública nos governos FHC (1995-2002) e Lula (2003-2010)

Principalmente a partir do final da década de 1990, com as crises internacionais que afetaram especialmente os países em desenvolvimento, passou-se a designar maior importância a temas como dívida pública, sua gestão e o desenvolvimento do mercado de títulos públicos. Nos últimos dezesseis anos da economia brasileira observamos diferentes momentos da situação do endividamento público. O crescimento da relação dívida pública/PIB e a piora da sua composição (em relação aos indexadores) são características do período de governo de Fernando Henrique Cardoso (1995-2002), enquanto o decréscimo da dívida pública em relação ao PIB, assim como a melhora de seu perfil, foram características presentes durante o governo de Luis Inácio “Lula” da Silva (2003-2010). É importante destacar que o cenário da economia mundial, em cada um dos períodos citados, influenciou diretamente na execução da política econômica, e, portanto, na gestão da dívida pública

Longitudinal study on skeletal changes during and after bionator therapy using metallic implants

Aim: To demonstrate the magnitude and direction of skeletal changes in the maxilla and mandible during and after the use of bionator, as well as their rotations. Methods: Partial superimposition on the maxilla and mandible on the metallic implants and total superimposition on the cranial base were performed at three periods, T1 before bionator therapy, T2 after bionator therapy, and T3 5.68 years after T2. Results: There was total clockwise maxillary rotation and counterclockwise mandibular rotation, in the North American technique, throughout the study period, as well as extensive remodeling on the condylar region, especially in vertical direction and on the gonial region in horizontal direction. Conclusions: The total maxillary rotation seemed to be significantly affected by therapy than the mandible. There was a clear change in the direction of condylar remodeling compared to the period of bionator therapy and posterior bionator therapy. Considering the entire study period, it was observed that intra-matrix rotation of the maxilla and mandible masked their total rotation, causing minimum changes in the matrix rotation.

Análise tomográfica da articulação temporomandibular no tratamento com Herbst em adulto jovem

Class II malocclusion features a high prevalence in Brazil, being considered as a routine in orthodontic clinics. A number of appliances are shown in the literature in order to correct Class II malocclusion with mandibular retrusion. Herbst´s fixed functional appliance, idealized by Emil Herbst (1905) and reintroduced, in the 1980´s, by Hans Pancherz is highlighted for maintaining the mandible continuously advanced, showing a shorter active treament time, an immediate esthetic impact on the facial profile, as well as requiring no patient´s commitment. Recent researches indicate the use of this appliance in individuals after pubertal growth surge. The aim of the present study is to show the orthodontics practitioner the option to use this appliance so as to treat Class II in individuals after the growth surge, obtaining satisfactory outcomes and further Class II correction.

Aparelho de Herbst associado a aparelhos fixos: descrição de técnica

This paper aims at describeconstruction and installation sequences of a new design of appliance that allows continuously protraction of the mandible, using the telescopic mechanism of the Herbst appliance. This appliance has the advantage to be easily assembled by the orthodontist, without the necessity of molding and the assistance of a specialized laboratory, as well as the constant permanence in the mouth of the patient for being fixed.

Avaliação das dimensões e relacionamento dos arcos dentários após tratamento com Bionator de Balters

The deficiency of data in the literature took us to evaluate the Bionator of Balters appliance in the alterations of the dimensions and the relationship of the dental archs in children with malocclusion Class II, division 1 of Angle. The experimental group was constituted by 36 pairs cast Caucasians patients, aged between 7 years and 10 months - 11 years and 8 months, being 10 females and 8 males. The Levene´s test showed statistical evidences of likeness among the groups. Statistical analysis was preceded and showed significant alterations (p < 0,005) in the variable indicatives of maxillary first molars' distance, overjet, upper arch total length, upper arch anterior length, right molar relationship, left molar relationship, right canine relationship and left canine relationship. On the other hand, there wasn't significant alteration related to the lower arch and maxillary intercanines distance. The Balters' Bionator appliance had a favorable effect in the improvement of the correction of the malocclusion in Class II (foremost in molars and canines relationship) and transversal increase of the upper arch, mainly in the posterior area of arch.

Estudio histológico del processo de reparación alveolar después de la aplicación tópica de la solucioón anestésica prilocaína 3 % con felipressina o,o3 ui/ml

The aim of this study was to evaluate the local anesthetic solution, composed by Prilocaine 3% and felipressin 0,03 UI/ml, influence on the alveolar repair process in rats after dental extraction. This research was previously approved by the Ethic Committee in Research of the Masters Degree Program in Oral and Maxillofacial Surgery of the Marília University (UNIMAR), Marília, São Paulo, Brazil. It was an experimental, randomly controlled study, with bifactorial analysis (group control versus experimental group, in function of the postoperative times (2 X 4)). For the accomplishment of this study 32 rats were used (Rattus norvegicus, albinus, Wistar), males, adults, weighing between 280 and 320 grams. The animals were selected and divided into Group I (control) and Group II (Citocain 3%® - Prilocaine 3% with felipressin 0,03UI/ml) with 16 rats each; being four animals of the Group I and four of the Group II, destined to the euthanasia in the postoperative periods of 3rd, 7th, 15th and 24th days. The histological analysis with base in the developed methodology, allowed us to conclude that the anesthetic solution of Citocain 3%® applied with gauze compress on the surgical dental wound, produced tissue events that committed the basic biological principles, that are responsible for the regeneration of the gingival epithelium and the alveolar process repair in rats. The Group I presented better results in the alveolar repair when compared to the Group II.

A utilização do enxerto ósseo autógeno para tratamento de lesão de furca grau II

Destruction of bone and periodontal ligament as a result of periodontal disease can lead to anatomical defects in the furcation area. Treatment of these lesions is a major challenge to the clinician. Periodontal instruments have limited access to this area and plaque and calculus removal from root surfaces are extremely difficult. For proper treatment planning a number of factors must be taken into consideration to achieve immediate and long term success. Surgical therapy associated with bone grafts may be a viable option in the treatment of class II furcation defects, aiming to restore lost tissues. The aim of this paper is to report a clinical case where a simplified surgical approach with the use of autogenous graft was used to treat a class II furcation defect Twelve months after the surgery, an increase in clinical attachment level and pocket depth reduction resulted in a complete closure of the furcation lesion.

ANP impairs the dose-dependent stimulatory effect of ANG II or AVP on H+-ATPase subcellular vesicle trafficking

The effect of angiotensin II (ANG II) or arginine vasopressin (AVP) alone or plus atrial natriuretic peptide (ANP) on H+-ATPase subcellular vesicle trafficking was investigated in MDCK cells following intracellular pH (pHi) acidification by exposure to20 mMNH4Cl for 2 min in a Na+-free solution containing Schering 28080, conditions under which H+-AT-Pase is the only cell mechanism for pHi recovery. Using the acridine orange fluorescent probe (5mM) and confocal microscopy, the vesicle movement was quantified by determining, for each experimental group, the mean slope of the line indicating the changes in apical/basolateral fluorescence density ratio over time during the first 5.30 min of the pHi recovery period. Under the control conditions, the mean slope was 0.079 ± 0.0033 min-1 (14) and it increased significantly with ANG II [10-12 and 10-7 M, respectively to 0.322 ± 0.038 min-1 (13) and 0.578 ± 0.061 min-1 (12)] or AVP [10-12 and 10-6 M, respectively to 0.301 ± 0.018 min-1 (12) and 0.687 ± 0.049 min-1 (11)]. However, in presence of ANP (10-6 M, decreases cytosolic free calcium), dimethyl-BAPTA/AM (5 × 10-5 M, chelates intracellular calcium) or colchicine (10-5 M, 2-h preincubation; inhibits microtubule-dependent vesicular trafficking) alone or plus ANG II or AVP the mean slopes were similar to the control values, indicating that such agents blocked the stimulatory effect of ANG II or AVP on vesicle trafficking. The results suggest that the pathway responsible for the increase in cytosolic free calcium and the microtu-bule-dependent vesicular trafficking are involved in this hormonal stimulating effect. Whether cytosolic free calcium reduction represents an important direct mechanism for ANP impairs the dose-dependent stimulatory effect of ANG II or AVP on H+-ATPase subcellular vesicle trafficking, or is a side effect of other signaling pathways which will require additional studies.

The development and deployment of FOTOS: a fast observation of trace organics system

Flüchtige organische Bestandteile (engl.: VOC) sind in der Atmosphäre in Spuren vorhanden, spielen aber trotzdem eine wichtige Rolle in der Luftchemie: sie beeinflussen das Ozon der Troposphäre, städtischen Smog, Oxidationskapazität und haben direkte und indirekte Auswirkungen auf die globale Klimaveränderung. Eine wichtige Klasse der VOC sind die Nicht-Methan-Kohlenwasserstoffe (engl.: NMHC), die überwiegend von anthropogenen Quellen kommen. Aus diesem Grund ist für Luftchemiker ein Messinstrument nötig, das die VOC, die NMHC eingeschlossen, mit einer höheren Zeitauflösung misst, besonders für Echtzeitmessungen an Bord eines Forschungsflugzeuges. Dafür wurde das System zur schnellen Beobachtung von organischen Spuren (engl.: FOTOS) entworfen, gebaut für den Einsatz in einem neuen Wissenschaftlichen Flugzeug, das in großen Höhen und über weite Strecken fliegt, genannt HALO. In der Folge wurde FOTOS in zwei Messkampagnen am Boden getestet. FOTOS wurde entworfen und gebaut mit einem speziell angefertigten, automatisierten, kryogenen Probensystem mit drei Fallen und einem angepassten, erworbenen schnellen GC-MS. Ziel dieses Aufbaus war es, die Vielseitigkeit zu vergrößern und das Störungspotential zu verringern, deshalb wurden keine chemischen Trocknungsmittel oder adsorbierenden Stoffe verwendet. FOTOS erreichte eine Probenfrequenz von 5.5 Minuten, während es mindestens 13 verschiedene C2- bis C5-NMHC maß. Die Drei-Sigma-Detektionsgrenze für n- und iso-Pentan wurde als 2.6 und 2.0 pptv ermittelt, in dieser Reihenfolge. Labortests bestätigten, dass FOTOS ein vielseitiges, robustes, hochautomatisiertes, präzises, genaues, empfindliches Instrument ist, geeignet für Echtzeitmessungen von VOC in Probenfrequenzen, die angemessen sind für ein Forschungsflugzeug wie HALO. Um die Leistung von FOTOS zu bestätigen, wurde vom 26. Januar bis 4. Februar 2010 ein Zwischenvergleich gemacht mit dem GC-FID-System am Meteorologischen Observatorium Hohenpeißenberg, einer WMO-GAW-globalen Station. Dreizehn verschiedene NMHC wurden innerhalb des Rahmens der GWA Data Quality Objectives (DQO) analysiert und verglichen. Mehr als 80% der Messungen von sechs C3- bis C5-NMHC erfüllten diese DQO. Diese erste Messkampagne im Feld hob die Robustheit und Messgenauigkeit von FOTOS hervor, zusätzlich zu dem Vorteil der höheren Probenfrequenz, sogar in einer Messung am Boden. Um die Möglichkeiten dieses Instrumentes im Feld zu zeigen, maß FOTOS ausgewählte leichte NMHC während einer Messkampagne im Borealen Waldgebiet, HUMPPA-COPEC 2010. Vom 12. Juli bis zum 12. August 2010 beteiligte sich eine internationale Gruppe von Instituten und Instrumenten an Messungen physikalischer und chemischer Größen der Gas- und Partikelphasen der Luft über dem Borealen Wald an der SMEAR II-Station nahe Hyyttiälä, Finnland. Es wurden mehrere Hauptpunkte von Interesse im Mischungsverhältnis der Alkane und im Isomerenverhätnis von Pentan identifiziert, insbesondere sehr unterschiedliche Perioden niedriger und hoher Variabilität, drei Rauchschwaden von Biomassen-Verbrennung von russischen Waldbränden und zwei Tage mit extrem sauberer Luft aus der Polarregion. Vergleiche der NMHC mit anderen anthropogenen Indikatoren zeigten mehrere Quellen anthropogener Einflüsse am Ort auf und erlaubten eine Unterscheidung zwischen lokalen und weiter entfernten Quellen. Auf einen minimalen natürlichen Beitrag zum 24h-Kreislauf von NOx wurde geschlussfolgert aus der Korrelation von NOx mit Alkanen. Altersschätzungen der Luftmassen durch das Isomerenverhältnis von Pentan wurden erschwert durch sich verändernde Verhältnisse der Quellen und durch Besonderheiten der Photochemie während des Sommers im hohen Norden. Diese Messungen zeigten den Wert des Messens leichter NMHC, selbst in abgelegenen Regionen, als einen zusätzlichen spezifischen Marker von anthropogenem Einfluss.

Google Images German Federal Court Entscheidung vom 29.04.2010, I ZR 69/08 With an English Introduction

The long-awaited verdict by the German Federal Court of Justice towards Google image search has drawn much attention to the problem of copyright infringement by search engines on the Internet. In the past years the question has arose whether the listing itself in a search engine like Google can be an infringement of copyright. The decision is widely seen as one of the most important of the last years. With significant amount of effort, the German Fede- ral Court tried to balance the interests of the right holders and those of the digital reality.

Impact of Team Familiarity in the Operating Room on Surgical Complications

BACKGROUND: The quality of surgical performance depends on the technical skills of the surgical team as well as on non-technical skills, including teamwork. The present study evaluated the impact of familiarity among members of the surgical team on morbidity in patients undergoing elective open abdominal surgery. METHODS: A retrospective analysis was performed to compare the surgical outcomes of patients who underwent major abdominal operations between the first month (period I) and the last month (period II) of a 6-month period of continuous teamwork (stable dyads of one senior and one junior surgeon formed every 6 months). Of 117 patients, 59 and 58 patients underwent operations during period I and period II, respectively, between January 2010 and June 2012. Team performance was assessed via questionnaire by specialized work psychologists; in addition, intraoperative sound levels were measured. RESULTS: The incidence of overall complications was significantly higher in period I than in period II (54.2 vs. 34.5 %; P = 0.041). Postoperative complications grade <3 were significantly more frequently diagnosed in patients who had operations during period I (39.0 vs. 15.5 %; P = 0.007), whereas no between-group differences in grade ≥3 complications were found (15.3 vs. 19.0 %; P = 0.807). Concentration scores from senior surgeons were significantly higher in period II than in period I (P = 0.033). Sound levels during the middle third part of the operations were significantly higher in period I (median above the baseline 8.85 dB [range 4.5-11.3 dB] vs. 7.17 dB [5.24-9.43 dB]; P < 0.001). CONCLUSIONS: Team familiarity improves team performance and reduces morbidity in patients undergoing abdominal surgery.

Distribución social de los conocimientos de medicina tradicional en los Andes: Estudios de caso de Perú y Bolivia

Los factores socio-económicos que influyen sobre los conocimientos de plantas medicinales de la población (personas no especialistas que se auto medican con plantas medicinales) han sido poco estudiado en la investigación etnobotánica. En este marco, el objetivo del trabajo de investigación fue analizar la distribución social del conocimiento sobre plantas medicinales en comunidades rurales de los Andes peruanos y bolivianos. Se realizaron entrevistas detalladas y ejercicios de listados libres en idioma Quechua con la ayuda de un intérprete local con 18 familias de un distrito rural de los Andes peruanos y 18 familias de una subcentral rural de los Andes bolivianos. Se recolectaron muestras botánicas de las plantas junto con los informantes en las dos áreas de estudios de caso. Un análisis cuantitativo de clasificación mostró que, en los dos estudios de caso, los vínculos de parentesco y la historia personal influye sobre las especies de plantas conocidas y usadas, en vez de otros factores como la edad, el nivel de educación, el estatuto socio-económico o la religión. El proceso de migración hacía los centros urbanos y las tierras bajas amazónicas, generalmente considerado como un factor importante en la pérdida de los conocimientos de medicina tradicional, solo tiene un impacto sobre el conocimiento de la población en el caso de familias que migran más de seis meses por año o de manera permanente. La migración no influye sobre los niveles de conocimientos de plantas medicinales ni sobre las estrategias terapéuticas de las familias que migran de forma temporal o por periodos más cortos de tiempo. Se demuestra que el impacto de factores socio-económicos externos que son generalmente considerados como la causa de la pérdida de los conocimientos de medicina tradicional en las altas tierras andinas es limitado. Además, los resultados de investigación implican que en zonas rurales donde la migración tiene un impacto sobre los conocimientos locales, la medicina tradicional podría ser mejor fortalecida si se trabaja estrechamente con familias y su red de parentesco extendida.
