O objetivo constitucional de desenvolvimento e o instrumento jurídico-normativo do conteúdo local na indústria petrolífera

On the petroleum industry, the State developed the Local Content police as a regulatory action to guarantee the preference of the national supply industry. Observing that, this paper will analyze the Local Content police aware of the constitutional goal of development as wright in the Constituição Federal de 1988. For it, will be used the hypothetical-deductive method for identifying the Local Content police as State strategy of development turn it in the object of critics in a dialectic way of thinking to in the final, present a conclusion about the police. As result was saw that the existent structure of the police at Brazil is inefficient, claiming for a rebuilt. For conclusion, is said that because of the inadequate construction of the Local Content police created inside of the Agência Nacional do Petróleo – ANP, the efficiency of the full potential of the police is been stopped, something that can be only corrected although a re-make of the police

Os limites constitucionais ao exercício de direito de patente e seus reflexos na indústria do petróleo, gás natural e biocombustíveis

This dissertation deals with the constitutional limits on the exercise of patent rights and its effects on the oil, natural gas and biofuels. Held with the support of ANP / PETROBRAS, It seeks to show how the law will limit the exercise of industrial property, based on a reinterpretation of private law by the constitutional development perspective . Today it is a fact that Petrobras, a Brazilian joint venture, has the latest technology in various sectors of the oil industry, and is one of the highest investments in developing new technologies. The overall objective of this thesis is to establish the relationship between the public interest of the Petroleum Industry, Natural Gas and Biofuels and constitutional limits to the free exercise of patent rights, then confirm or refute our hypothesis that Article 71 on Industrial Property Law is contrary to the existing objectives in Article 3 of the Constitution of the Federative Republic of Brazil. The research aims to examine the relevant aspects of the legal nature attributed to IPGN constitutionally confronting the constitutional limits on the free exercise of patent rights, with the purpose to outline the state of the performance limits in the regulation of the economy, in particular the application of feasibility limitations on the right of property in favor of national interest on the strategic energy industry. The aim is to confront the fundamental rights to property and economic development, against the public interest, limiting these first. As to the objectives, the research will be theoretical and descriptive and harvest of industrial property, respect the possible impact of regulatory standards and limiting the right of ownership in the oil industry. To establish how the state will mitigate the intellectual property right, we discuss, at first, a definition of public interest from the general theory of state and sovereign character in order to establish a new concept of national interest and popular interest, which will in turn the definition of our concept of public interest. In the second phase, will be addressed the issue of industrial property rights and how to will be free exercise thereof, in the constitutional sphere, infra, and demonstrating the use of industrial property rights with examples of market and IPGN . After situating the industrial property rights in the constitution and national legislation, establish their relationship with the national and regional development, will be addressed in this chapter in particular the patent law, as most usual form of intellectual property protection in IPGN. Used a study highlighting the number of patents in the area of the analyzed industry, demonstrating with hard data the importance of a sector for industrial development. The relationship between the social function of intellectual property and the constitutional objective of development was characterized to demonstrate the strategic nature of oil to Brazil in the national and international scene, and put into question the hypothesis of the research which provides that even with large investments the lack of legal certainty in the sector turns out not to have a considerable volume of investment as it could.

Reprogramação de células-tronco mesenquimais em neurônios utilizando genes pró-neurais

A possibilidade de repor células perdidas em doenças neurodegenerativas através de transplantes com células-troncos das mais diversas fontes vem sendo amplamente estudada. As células-tronco adultas (CTA) podem ser facilmente isoladas e sua utilização na pesquisa não envolve questões éticas e religiosas. Além disso, estas células são menos propícias à transformação tumoral do que células-tronco embrionárias, outra importante fonte de células para terapias celulares. No entanto, as CTA são, em estados fisiológicos, restritas a geração de células dos seus tecidos de origem, o que poderia limitar a sua utilização. Porém, nos últimos anos, uma série de técnicas vem sendo descritas com o objetivo de reverter tais limitações. Neste trabalho, nós investigamos a capacidade das células-tronco mesenquimais adultas, isoladas de camundongos ou do cordão umbilical humano, serem induzidas a adquirir um fenótipo neuronal de forma direta, sem passar por um estágio de célula progenitora ou pluripotente, através da reprogramação genética com genes pró-neurais. Nossos resultados indicam que tanto células-tronco mesenquimais adultas murinas quanto humanas podem ser reprogramadas em neurônios após a expressão combinada de Sox2 e Ascl1 ou Sox2 e Neurog2. As células reprogramadas exibem morfologias compatíveis com o fenótipo neuronal, expressam proteínas típicas de neurônios maduros, apresentam a capacidade de gerar potenciais de ação repetitivos e formam conexões sinápticas com outros neurônios presentes no cultivo. Portanto, nosso trabalho apresenta a primeira evidência de reprogramação direta de células-tronco mesenquimais humanas em neurônios funcionais.

Reprogramming of distinct astroglial populations into specific neuronal subtypes in vitro and in vivo

Recently, the field of cellular reprogramming has been revolutionized by works showing the potential to directly lineage-reprogram somatic cells into neurons upon overexpression of specific transcription factors. This technique offers a promising strategy to study the molecular mechanisms of neuronal specification, identify potential therapeutic targets for neurological diseases and eventually repair the central nervous system damaged by neurological conditions. Notably, studies with cortical astroglia revealed the high potential of these cells to reprogram into neurons using a single neuronal transcription factor. However, it remains unknown whether astroglia isolated from different regions of the central nervous system have the same neurogenic potential and generate induced neurons (iN) with similar phenotypes. Similarly, little is known about the fate that iNs could adopt after transplantation in the brain of host animals. In this study we compare the potential to reprogram astroglial cells isolated from the postnatal cerebral cortex and cerebellum into iNs both in vitro and in vivo using the proneural transcription factors Neurogenin-2 (Neurog2) and Achaete scute homolog-1 (Ascl1). Our results indicate cerebellar astroglia can be reprogrammed into induced neurons (iNs) with similar efficiencies to cerebral cortex astroglia. Notably however, while iNs in vitro adopt fates reminiscent of cortical or cerebellar neurons depending on the astroglial population used for reprogramming, in situ, after transplantation in the postnatal and adult mouse brain, iNs adopt fates compatible with the region of integration. Thus, our data suggest that the origin of the astroglial population used for lineage-reprogramming affects the fate of iNs in vitro, but this imprinting can be overridden by environmental cues after grafting.

Inverse Association Between Gluteofemoral Obesity and Risk of Barrett's Esophagus in a Pooled Analysis

BACKGROUND & AIMS: Gluteofemoral obesity (determined by measurement of subcutaneous fat in hip and thigh regions) could reduce risks of cardiovascular and diabetic disorders associated with abdominal obesity. We evaluated whether gluteofemoral obesity also reduces risk of Barrett's esophagus (BE), a premalignant lesion associated with abdominal obesity.

METHODS: We collected data from non-Hispanic white participants in 8 studies in the Barrett's and Esophageal Adenocarcinoma Consortium. We compared measures of hip circumference (as a proxy for gluteofemoral obesity) from cases of BE (n=1559) separately with 2 control groups: 2557 population-based controls and 2064 individuals with gastroesophageal reflux disease (GERD controls). Study-specific odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using individual participant data and multivariable logistic regression and combined using random effects meta-analysis.

RESULTS: We found an inverse relationship between hip circumference and BE (OR per 5 cm increase, 0.88; 95% CI, 0.81-0.96), compared with population-based controls in a multivariable model that included waist circumference. This association was not observed in models that did not include waist circumference. Similar results were observed in analyses stratified by frequency of GERD symptoms. The inverse association with hip circumference was only statistically significant among men (vs population-based controls: OR, 0.85; 95% CI, 0.76-0.96 for men; OR, 0.93; 95% CI, 0.74-1.16 for women). For men, within each category of waist circumference, a larger hip circumference was associated with decreased risk of BE. Increasing waist circumference was associated with increased risk of BE in the mutually adjusted population-based and GERD control models.

CONCLUSIONS: Although abdominal obesity is associated with increased risk of BE, there is an inverse association between gluteofemoral obesity and BE, particularly among men.

Response process and test-retest reliability of the Context Assessment for Community Health tool in Vietnam

BACKGROUND: The recently developed Context Assessment for Community Health (COACH) tool aims to measure aspects of the local healthcare context perceived to influence knowledge translation in low- and middle-income countries. The tool measures eight dimensions (organizational resources, community engagement, monitoring services for action, sources of knowledge, commitment to work, work culture, leadership, and informal payment) through 49 items. OBJECTIVE: The study aimed to explore the understanding and stability of the COACH tool among health providers in Vietnam. DESIGNS: To investigate the response process, think-aloud interviews were undertaken with five community health workers, six nurses and midwives, and five physicians. Identified problems were classified according to Conrad and Blair's taxonomy and grouped according to an estimation of the magnitude of the problem's effect on the response data. Further, the stability of the tool was examined using a test-retest survey among 77 respondents. The reliability was analyzed for items (intraclass correlation coefficient (ICC) and percent agreement) and dimensions (ICC and Bland-Altman plots). RESULTS: In general, the think-aloud interviews revealed that the COACH tool was perceived as clear, well organized, and easy to answer. Most items were understood as intended. However, seven prominent problems in the items were identified and the content of three dimensions was perceived to be of a sensitive nature. In the test-retest survey, two-thirds of the items and seven of eight dimensions were found to have an ICC agreement ranging from moderate to substantial (0.5-0.7), demonstrating that the instrument has an acceptable level of stability. CONCLUSIONS: This study provides evidence that the Vietnamese translation of the COACH tool is generally perceived to be clear and easy to understand and has acceptable stability. There is, however, a need to rephrase and add generic examples to clarify some items and to further review items with low ICC.

Comparative study between the effects of hyaluronic acid and acid galactan purified from eggs of the mollusk Pomacea sp in wound healing

To compare the effect of hyaluronic acid (HA) and of AG on the healing of intestine wounds. Methods: The semi-purified extract of the eggs of the mollusc was obtained by fractionation with ammonium sulfate and purification for ion-exchange chromatography. The obtained galactans were eluted in water (neutral galactan) and in 0.1 and 0.2M NaCl (acidic galactans). The in vivo study was performed with 45 “Wistar” rats, separated in three groups (n=15). Solutions containing HA 1%, GA 1% or saline solution 0,9%, was placed topically on the sutures of wounds in the small intestine of the rats. After 05, 10 and 21 days the animals were sacrificed and biopsy of the healing tissue was done. Results: The hystologic grading was more significant for HA and AG groups when compared to the group C. AG stimulated the appearance of macrophages, giant cells and increase in the concentration of collagen in the area of the wound when compared to HA. Conclusion: The topical use of GA in intestinal wounds promoted the anticipation of events that are important in the wound healing

Kommunikation mellan patient och ortopedingenjör : En kvalitativ studie

En studie har genomförts med syftet att undersöka diabetespatienters tolkning av informationen som ges av deras respektive ortopedingenjör under ett patientmöte samt undersöka vad ortopedingenjören anser sig ha förmedlat för information till patienten under patientmötet. Metoden i studien är kvalitativ där intervjuer med semistrukturerade öppna frågor har använts. I studien ingick två ortopedingenjörer samt två diabetespatienter. Efter avslutade intervjuer har materialet från intervjuerna analyserats och bildat kategorier. Dessa kategorier har sedan använts för att finna skillnader samt likheter mellan ortopedingenjörens och patientens tolkningar. Patientmötens har spelats in för att få möjligheten att se vart missförstånd uppstått. Genomgående i resultatet var att ortopedingenjören anser sig ha förmedlat mer information än vad patienten beskriver under intervjuerna. Några missförstånd upptäcktes men kommunikationen mellan parterna var god.  

Käsiteanalyysi yhteiskunnallisen yrityksen liiketoimintastrategiasta vähittäiskaupan toimialalla

Kuluttajien arvojen muutosten erityisesti eettisyyttä korostavaan suuntaan ja individualisaation seurauksena markkinat ovat fragmentoituneet. Lisäksi julkista sektoria on alettu kestävyysvajeen ja poliittisten linjausten seurauksena yksityistämään ja markkinaehtoistamaan. Näiden muutosten seurauksena on alkanut syntyä uudenlaista yhteiskunnallista yritystoimintaa, joka ei pohjaudu voitontavoittelulle, vaan yhteiskunnassa ilmenevien ongelmien ratkaisemiselle. Tutkimuksessa on selvitetty, mitä tarkoittavat yhteiskunnallisten yritysten sekä liiketoimintastrategioiden käsitteet vähittäiskaupan toimialalla. Käsitteiden määrittelyn avulla on pyritty selvittämään millaisia liiketoimintastrategioita yhteiskunnalliset yritykset voivat hyödyntää vähittäiskapan toimialalla. Yhteiskunnallisten yritysten sekä liiketoimintastrategioiden käsitettä vähittäiskaupan toimialalla on selvitetty käsiteanalyysin avulla. Käsiteanalyysissä on muodostettu tietopohja alan julkaisujen avulla, pääkäsitteitä on analysoitu vertailtu suhteessa niiden lähikäsitteisiin. Käsitteet on purettu osiin, eli nostettu esiin erilaisia tulkintoja sekä näkemyksiä ja pohdittu niitä. Analyysiä on tehty hermeneuttisen kehän avulla. Yhteiskunnallisten yritysten tavoitteena on yhteiskunnallisten ongelmien lieventäminen tai poistaminen. Valtaosa niiden voitoista käytetään yhteiskunnallisten tavoitteiden edistämiseen. Niiden toimintaan kuuluu olennaisesti sidosryhmien osallistaminen yrityksen päätöksentekoon. Niiden liiketoiminta on avointa ja läpinäkyvää. Liiketoimintastrategialla tarkoitetaan yhdellä toimialalla noudatettavia strategioita. Vähittäiskaupan toimialalla yhteiskunnallisten yritysten liiketoimintastrategiat voidaan jakaa kilpailu- ja yhteistyöstrategioihin. Kilpailustrategioita ovat tuottavuus ja yrityksen asemointi kuluttajien mieleen. Yhteistyöstrategioita ovat arvon yhteistuotanto ja arvoverkostoyhteistyö sidosryhmien kanssa. Yhteiskunnallisen yrityksen käsite on moninainen ja vielä osin jäsentymätön. Sen toiminnassa keskeistä on yhteiskunnallisen hyvän tuottaminen sekä voittojen ohjaaminen tämän tarkoituksen toteuttamiseksi. Yritystoiminnan perusedellytys on kannattavuus, joka saavutetaan kilpailuedun avulla ja joka pohjautuu kilpailijoita parempaan tuottavuuteen tai ylivertaiseen asiakkaalle tuotettuun arvoon. Ylivertainen asiakasarvo saavutetaan asemoimalla yritys halutulla tavalla kuluttajien mieliin asiakaslupauksen kautta. Tuottavuus ja asemointi tuotetaan yrityksen arvoketjussa suhteellisen resurssiedun kautta, mikä pohjautuu arvoketju-, ympäristö- ja yritysanalyyseihin
