Descoberta desde 1889 por Hite, a alta pressão hidrostática tem ganhado cada vez mais espaço na indústria de alimentos nos últimos vinte anos. Com todas as vantagens a ela atribuída, essa tecnologia vem para suprir um mercado onde o consumidor exige um alimento seguro e de qualidade cada vez maior. Uma alternativa aos tratamentos térmicos convencionais, a alta pressão hidrostática não somente se sobressai pela sua eficiência tecnológica, oferecendo conservação de atributos sensoriais e nutricionais dos alimentos, como é capaz de proporcionar alimentos seguros microbiologicamente, conferindo uma maior qualidade aos produtos quando comparada a outros tratamentos. Esta revisão sistemática de literatura teve como objetivo discutir a aplicação da alta pressão hidrostática na indústria alimentícia e seu papel como uma tecnologia promissora. A metodologia consistiu em selecionar textos científicos específicos sobre o assunto a partir da pesquisa bibliográfica em banco de dados eletrônicos e livros. Quatro livros e nove textos científicos foram selecionados, entre o período de 2002 e 2014. Conclui-se com esta revisão sistemática de literatura que a alta pressão hidrostática apresenta um futuro promissor na indústria de alimentos. No entanto, pesquisas são necessárias para um estabelecimento de padrões de valores atribuídos ao processo (como pressão, tempo e temperatura, por exemplo) especificamente para cada produto submetido à tecnologia

A ideia de uma nutrição que, além de suprir as necessidades nutricionais básicas do organismo também tem como objetivo a prevenção de doenças, ganha cada vez mais ênfase sobre a égide dos alimentos funcionais e dos nutracêuticos. Nesse contexto a curcumina, um pigmento amarelo-alaranjado extraído do rizoma da planta Curcuma longa L. se destaca como um promissor nutracêutico, apresentando um amplo potencial terapêutico e a cada dia encontra maior embasamento científico com a elucidação de seus mecanismos de ação sobre vários alvos moleculares importantes para a fisiopatologia de diversas doenças. A curcumina é bastante conhecida e explorada pela medicina asiática tradicional, principalmente pelas medicinas Ayurvédica e Chinesa. Utilizando o Pubmed e o Scielo como banco de dados para a pesquisa de trabalhos científicos, foi elaborada uma revisão bibliográfica com a compilação de estudos com diversos enfoques em relação à curcumina, a saber: i) características físico-químicas da curcumina; ii) propriedades anti-inflamatória, antioxidante, antidiabética, antitumoral, antiviral, antibacteriana, antiparasitária e antifúngica; iii) estratégias recentemente utilizadas para melhorar sua biodisponibilidade, tais como co-admnistração da piperina, síntese de análogos moleculares e sistemas inovadores de entrega como os sistemas coloidais (lipossomas e nanopartículas) e a complexação com ciclodextrina.

This research examines the merits of hallucinogenic plants considered and/or psychoactive substances, such as Cannabis sativa and Ipomoea violacea, using the isotope rates of stable isotope of oxygen (18O) and nitrogen (15N), continuing projects already developed by the research group at the Center for Stable Isotope (CIE), which evaluated the isotopes carbon-13. This paper helps in creating a database that we intent to use in evaluation of each plant merit. Through the IRMS (Isotope-Ratio Mass Spectrometry) technique, it has shown that some of the 24 samples of marijuana (Cannabis sativa L.) evaluated were similar to those grown in the regions of Fairbanks and Tanacross Alaska, USA. In turn, the 50 samples of Ipomoea violacea, coming from Botucatu (SP) and Três Lagoas (MS), got their differences detected, in order to clearly identify the discrepancies between their growing regions. Thus, it was possible not only to track the geographical differences between marijuana samples collected from different regions, but also evaluate the isotopic variation of leaf, flower and seed of Ipomoea violacea. With this database, it was possible to determine the origin region of the drug and/or detect where the cultivation was carried out, aiding in the search of the traffic control agencies, such as the Federal Police in Brazil

This work aims to evaluate the different trajectories in terms of production structure, technological capabilities and performance in international trade of pharmaceutical industries in Brazil and India. For this, we build international trade indicators, based on data provided by the COMTRADE, the UN database for trade. Through the indicators, it is observed that the countries have different results in the catch-up process of the pharmaceutical industry. India has built a productive structure strongly based on generic drugs, with which it is able to greatly meet domestic demand and export to many countries worldwide. Brazil remains in a position of dependence of foreign production, with a high level of imports and exports to the region of Latin America

Analyzing evidences of the LEADER approach in the Territories of Citizenship Program consists in the immediate objective of this paper. Considering the current context in which the territorial approach takes on the challenge of promoting a less excluding development, the deepening of discussions and experiences highlighted in national and international scope can add elements for analysis and creation of proposals for a more efficient development. Methodologically, a qualitative analysis of bibliographic data and interviews involving focal subject types was performed. In the analysis performed it was possible to understand that the policy of territorial approach is necessary, but it has structural implications that hinder the work of those who should mediate and sensitize the most excluded social groups. Therefore, so that there is an effective policy it would be necessary to create participatory and emancipatory models able to produce structural changes.

Introduction: The configuration and dimensions of the upper airway are determined by anatomical structures such as soft tissues, muscles and craniofacial skeleton, composing or surrounding the pharynx. Anatomical abnormalities of the soft tissues and / or craniofacial skeleton may become more narrow upper airway. The orthognathic surgery, which is used in the correction of dentoskeletal deformities, also causes changes in the upper airway. Objective: In view of the facts presented, this article aims to review the literature on the changes of the upper airway in patients’ class III undergoing orthognathic surgery. Methodology: International Literature on Health Sciences (Pubmed ) and Port Journals CAPES original and review published between 1990 and 2010, in two bibliographic databases articles were selected. Results: thirty-nine (39) articles were selected for writing this review. Conclusion: The upper airway deformity and dental- skeletal class III should be carefully evaluated prior to orthognathic surgery and whenever surgical planning permit should prefer the maxillary advances to mandibular setbacks

The Health Sciences, prior to the planning of prevention programs, adopt the tools to analyze the population profile, entitled epidemiological surveys, to obtain data on the need for heathcare and the possibility of treating health events. The aim of this study was to evaluate dental conditions in schoolchildren, aged five to fourteen, enrolled in public schools in Américo Brasiliense, SP Brazil. The dmft and DMFT index, caries experience, and prevalence of fluorosis were analyzed. For this epidemiological study, 1,137 children were selected. Four calibrated dentists performed oral exams according to WHO criteria (1997). The data were collected using descriptive analyses. The results showed that 94% of the five-year-old children were caries free, and the value of dmft was 1.44. DMFT was 1.19 in 12-year-olds. The lowest and the highest fluorosis prevalence could be observed in eight and fourteen-year-olds, respectively. It could be concluded that the city of Américo Brasiliense has developed respectful educational and preventive oral health programs which presented satiosfactory results in the present epidemiological study.

The Family Health Strategy is a primary care public policy that is becoming a decisive step towards the transformation of the Brazilian healthcare model. This study evaluated the dental knowledge among individuals who attended a Family-Health Unit (FHU) in the city of São Carlos, SP, Brazil. Methods: The evaluation was based on a questionnaire with 20 questions about oral health, prevention and development of dental caries and periodontal disease. The questionnaire was given to 168 individuals, over 18 years of age and both sexes, to fill out under the supervision of a trained dentist. After data collection, the answers contained in the original questionnaires were entered into a database built using the program Excel® (Microsoft Corporation, USA) and a descriptive statistical analysis was done. Results: 66.67% of the subjects reported having received information about dental caries and periodontal disease before attending the FHU, and dentists were cited as the main source of such information (60.71%). With regard to dental caries, 70.24% of the individuals stated that they knew about the subject, but the majority of answers revealed incorrect explanation of it. The multifactorial etiology (bacteria/sugar/poor hygiene) was not mentioned. A low percentage of subjects (24.40%) claimed to know what periodontal disease is, and of these, the highest percentage of responses was related to gingivitis (26.83%) and gingival bleeding (12.20%). Out of all subjects, 80.36% affirmed that oral hygiene is important, and among them, the main reasons cited were the maintenance of oral health (29.63%), to avoid diseases (16.30%) and to preserve and prevent disease (14.81%). Conclusion: Responses from the questionnaires revealed deficient dental knowledge among the individuals. To improve the understanding about this issue, the information obtained through the questionnaire can be used to develop educational programs that will focus specifically on the major deficiencies found.
