A novel bradykinin potentiating peptide isolated from Bothrops jararacussu venom using catallytically inactive oligopeptidase EP24.15

Characterization of the peptide content of venoms has a number of potential benefits for basic research, clinical diagnosis, development of new therapeutic agents, and production of antiserum. Here, we use a substrate-capture assay that employs a catalytically inactive mutant of thimet oligopeptidase (EC 3.4.24.15; EP24.15) to identify novel bioactive peptides in Bothrops jararacussu venom. Of the peptides captured with inactive EP24.15 and identified by mass spectrometry, three were previously identified bradykinin-potentiating peptides (BPP), < ENWPHPQIPP (Xc), < EGGWPRPGPEIPP (XIIIa) and < EARPPHPPIPP (XIe) (where < E is a pyroglutamyl residue). In addition, we identified a novel BPP peptide containing additional AP amino acids in the C-terminus (< EARPPHPPIPPAP); this novel peptide was named BPP-AP. Next, dermal and muscle microcirculations were visualized using intravital microscopy to establish the roles of peptides BPP-XIe and BPP-AP in this process. After local administration of peptide BPP-XIe (0.5 mu g.mu L-1), leukocyte rolling flux and adhesion were increased by fivefold in post-capillary venules, without any increments in vasodilatation of arterioles compared to control experiments. In contrast, local administration of BPP-AP (0.5 mu g.mu L-1) potently induced vasodilatation of arterioles (nearly 100% increase compared with the vehicle saline control), with only a small increase in leukocyte rolling flux. Therefore, the novel BPP-AP described herein has pharmacological advantages compared to the BPP-XIe. The present study further suggests that inactive oligopeptidase EP24.15 is a useful tool for the isolation of bioactive peptides from crude biological samples.

A informação no processo de descentralização administrativa do setor saúde: o caso do cartão nacional de saúde em Niterói

A importância da informação como recurso estratégico nas organizações conduz à relevância que o projeto Cartão Nacional de Saúde (CNS) do SUS assume na reestruturação do setor público de Saúde, que busca um novo modelo de gestão, nas três esferas de governo. A descentralização da gestão, como um processo extremamente dinâmico e participativo, rede fine os papéis dos gestores, que assumem novas responsabilidades, exigindo um aparato burocrático mais flexível. Seus desafios são muitos, visto que as organizações de saúde são sempre complexas. Neste estudo buscou-se o entendimento da dinâmica organizacional e de sua adaptação às mudanças impostas pelo ambiente, com base no referencial teórico proposto por H. Mintzberg e sua aplicação às organizações do SUS. A experiência de implantação desse novo sistema de informação, CNS, de abrangência nacional, é analisada em seus aspectos locais, com seus êxitos e dificuldades, no município de Niterói.

As propostas educacionais maranhenses no Império (1834-1889)

A instruçio p~blica no Maranhão sofreu certas mudanças, a partir do Ato Adicibnal (1834), que coiocou sob a responsabilidade das Administrações provinciais a direção do ensino p~blico, primario e secundario no Brasil. No s~culo passado, (XIX), no final dos anos 30 e durante os decênios de 40 e 50, houve, no Maranhão, um certo esforço do Estado, no sentido de exercer um contróle maior sobre a instrução provincial e de desenvolver ~ uma. maior clientela o ensino elementar. Nessa época, foram. pr~:))lr?v1dos pela Administração local os primeiros incentivos ã di fusão do ensino t~cnico e agrIcola; e reorganizado o ensino securidirio com a criação do Liceu Maranhense. Nas ~ltimas d~cadas do Imperio, entretanto, o Estado demonstrou um gra~ de desinteresse pelo desenvolvimento da educação escolar no Maranhão. As realizações oficiais dessa ~po~a, nos diver sos nIveis, ' foram insignificantes. A Administração Local, decretando o livre exeycIcio do ensino, em 1874, demonstrou legalmente o descaso a que relegou a instrução p~blica pr~ vincial. As tendências verificadas no ensino p~blico maranhense, nesse perIodo (1834-1889), for~m sobretudo, por particularidades do processo determinadas, polItico-econô mico marannense da ~poca. Nos primeiros decênios (final .de 30 : ê : · d~ca.das 40 ~. 50)', a sit~ação pó'Útiêa . ~aranhens.e · ;'.ar.act.eri:za·v~-. se por um grande empenho dos fazendeiros (fração da classe dominante no poder) em garantir a ordem e buscar a nia. No âmbito econômico, destacava-se um afã por hegem2. reformas materiais, visando ao soerguimento da economia mercantil. Ji nos Gltirnos dec~nios analisados, a situação p61Itico-ec2. n~mica traduzia-se por um maior fortalecimento do poder Político dos fazendeiros, mas com uma grave crise econômica. As condições sociais maranhenses nas primeiras décadas favo receram, pois, o surgimento de uma maior preocupação do Es tado pela educação escolar, enquanto que, na última fase, a situação político-econômica maranhense desestimulou um interesse maior do Estado pelo desenvolvimento do ensino público no Maranhão.

Diagnóstico e formulação de políticas públicas em municípios abaixo de 50 mil habitantes : recomendações e instrumentos

As discussões sobre o uso de indicadores aplicado à formulação de políticas públicas ganham força no cenário nacional. O governo federal e o estadual, a partir de suas iniciativas, vêm induzindo os gestores municipais a elaborarem diagnósticos e pensarem de forma planejada sobre a realidade que desejam interferir. Neste sentido, se evidencia a importância do uso de informações para potencializar os efeitos em todo o ciclo de políticas públicas: diagnóstico, formulação, implementação e avaliação. Entre os desafios que englobam o tema está pensar instrumentos apropriados para apoiar os gestores de pequenos Municípios a fazer diagnósticos baseados no conhecimento estruturado da realidade. O presente trabalho tem a finalidade de contribuir para esta discussão por meio de recomendações que visam o aperfeiçoamento de um dos instrumentos existentes e já utilizados para este fim: a publicação “Construindo o diagnóstico municipal: uma metodologia”. Esta publicação foi elaborada em 2008 pelo Centro de Estudos e Pesquisas de Administração Municipal (CEPAM) e Instituto de Economia da Universidade de Campinas com o intuito de fornecer aos recém-empossados prefeitos, condições de obter as informações básicas necessárias para elaboração de planejamento municipal. Passados quatro anos do lançamento da publicação, a equipe do CEPAM pretende elaborar uma segunda versão do documento direcionada aos Municípios de menor porte, o que justifica a proposta desse trabalho em sugerir adequações para seu aperfeiçoamento. Para chegar a tal objetivo, a equipe de mestrandos envolvida com o trabalho lançou mão de três instrumentos de pesquisa: investigação crítica da publicação CEPAM, entrevistas com prefeitos de pequenos municípios e entrevistas qualitativas com especialistas de instituições produtoras e disseminadoras de dados. Ao todo foram realizadas entrevistas com 22 prefeitos, 9 especialistas em diagnósticos aplicados a políticas públicas e analisados cerca de 250 indicadores de abrangência multidimensional. Os resultados das mais de trinta entrevistas realizadas apontaram para uma série de especificidades que dificultam o uso de diagnósticos por administrações municipais menores. A partir do conteúdo dos entraves e constatações levantados mapearam-se os temas considerados prioritários, que foram classificados em quatro áreas de intervenção e quatorze recomendações para subsidiar o CEPAM na atualização da publicação a ser direcionada aos Municípios abaixo de 50 mil habitantes.

As parcerias entre prefeituras paulistas e o setor privado na política educacional: expressão de simbiose?

L'article présente les résultats finaux de l'enquête inter-institutionnelle qui a eu pour objet d'analyser la nature et les conséquences de partenariats conclus entre des secteurs privés et des gouvernements municipaux de la métropole de São Paulo pour le service de l'éducation à la maternelle et à l'enseignement élémentaire. La période a correspondu aux années 1996 à 2006, sachant que la perception d'une augmentation des responsabilités des municipalités pour l'offre éducationnelle, suite à la municipalisation de l'enseignement élémentaire, pourrait stimuler la sous-traitance de l'offre et la privatisation de l'éducation municipale. L'étude présente des tendances en relation avec trois modalités de partenariat: subvention publique pour l'offre de places en institutions privées de l'éducation élémentaire; acquisition de systèmes privés de l'enseignement et recours à des cabinets de conseil privés pour la gestion de l'éducation municipale. Les tendances perçues dans l'analyse indiquent que les actuelles relations entre les sphères publiques et privées dans le champ de l'éducation, suite à la décentralisation survenue dans le secteur, représentent un mouvement dans le sens de sa privatisation.

Attitude of Brazilian veterinarians in the recognition and treatment of pain in horses and cattle

Objective: The objective of this study was to assess the use of analgesics, describe the attitudes of Brazilian veterinarians towards pain relief in horses and cattle and evaluate the differences due to gender, year of graduation and type of practice. Study design: Prospective survey. Methods: Questionnaires were sent to 1000 large animal veterinarians by mail, internet and delivered in person during national meetings. The survey investigated the attitudes of Brazilian veterinarians to the recognition and treatment of pain in large animals and consisted of sections asking about demographic data, use of analgesic drugs, attitudes to pain relief and to the assessment of pain. Descriptive statistics were used to analyze frequencies. Simple post hoc comparisons were performed using the chi-square test. Results: Eight hundred questionnaires were collected, but 87 were discarded because they were incomplete or blank. The opioid of choice for use in large animals was butorphanol (43.4%) followed by tramadol (39%). Flunixin (83.2%) and ketoprofen (67.6%) were the most frequently used NSAIDs by Brazilian veterinarians. Respondents indicated that horses received preoperative analgesics for laparotomy more frequently (72.9%) than cattle (58.5%). The most frequently administered preoperative drugs for laparotomy in horses were flunixin (38.4%) and xylazine (23.6%), whereas the preoperative drugs for the same surgical procedure in cattle were xylazine (31.8%) and the local administration of lidocaine (48%). Fracture repair was considered the most painful surgical procedure for both species. Most veterinarians (84.1%) believed that their knowledge in this area was not adequate. Conclusions and clinical relevance: Although these Brazilian veterinarians thought that their knowledge on recognition and treatment of pain was not adequate, the use of analgesic in large animals was similar in Brazil to that reported in other countries. © 2013 Association of Veterinary Anaesthetists and the American College of Veterinary Anesthesia and Analgesia.

Anti-hyperalgesic and anti-inflammatory activity of Alternanthera maritima extract and 2″-O-α-L-rhamnopyranosylvitexin in mice

Alternanthera maritima are used in Brazilian popular medicine for the treatment of inflammatory and infectious diseases. Species of Alternanthera have demonstrated biological activities in previous scientific studies. The aim of this study was to determine whether the ethanol extract of the aerial parts of A. maritima (EEAM) and the isolated compound 2″-O-α-L-rhamnopyranosyl-vitexin inhibit mechanical hyperalgesia and parameters of inflammation in mice. The oral administration of EEAM significantly inhibited carrageenan (Cg)-induced paw edema and reduced leukocyte migration into the pleural cavity. 2″-O-α-L-rhamnopyranosylvitexin significantly inhibited paw edema and reduced both leukocyte migration and the leakage of protein into the pleural cavity. Both EEAM and 2″-O-α-L-rhamnopyranosylvitexin significantly prevented the Cg-induced hyperalgesia. Local administration of 2″-O-α-L-rhamnopyranosylvitexin significantly prevented the Cg- and tumor necrosis factor (TNF)-induced hyperalgesia. In conclusion, this study demonstrated that EEAM is an anti-inflammatory and anti-hyperalgesic agent, and the results suggested that 2″-O-α-L-rhamnopyranosylvitexin is responsible for the effects of EEAM and the mechanism involves the TNF pathway.

Manutenção em próteses implantossuportadas: peri-implantite

The identification and treatment of peri-implant infections are an essential stage in the maintenance of dental implants, reflecting the longevity of rehabilitation. Therefore, the aim of the study was to conduct a literature review addressing peri-implantitis in dental implants in order to guide planning for the longevity of oral rehabilitation. It was conducted a detailed search strategy by the PubMed / Medline Dentistry and Oral Science, it was used as descriptors: “peri-implantitis” and “Dental Implant”, until July 2013. From 566 articles, after a review, according to the inclusion criteria, 34 articles were selected. The results were grouped together in topics (concept, etiology, diagnosis, surgical and nonsurgical, and aspects of oral rehabilitation) for further discussion and conclusions. Conclusions: The accumulation of plaque has been associated with a higher propensity to peri-implantitis. There is a higher incidence of the peri-implantitis disease among patients with previous history of periodontal disease. The local administration of antibiotics and association with mouthwashes / topical use are indicated as suitable for the treatment of moderate peri-implantitis.

Differential role of CB1 and TRPV1 receptors on anandamide modulation of defensive responses induced by nitric oxide in the dorsolateral periaqueductal gray

CB1, TRPV1 and NO can regulate glutamate release and modify defensive behaviors in regions related to defensive behavior such as the dorsolateral periaqueductal gray (dIPAG). A possible interaction between the endocannabinoid and nitrergic systems in this area, however, has not been investigated yet. The objective of the present work was to verify if activation of CB1 or TRPV1 receptors could interfere in the flight responses induced in rats by the injection of SIN-1, an NO donor, into the dIPAG. The results showed that local administration of a low dose (5 pmol) of anandamide (AEA) attenuated the flight responses, measured by the total distance moved and maximum speed in an open arena, induced by intra-dIPAG microinjection of SIN-1 (150 nmol). URB597 (0.1 nmol), an inhibitor of anandamide metabolism, produced similar effects. When animals were locally treated with the CB1 receptor antagonist AM251 the effective AEA dose (5 pmol) increased, rather than decreased, the flight reactions induced by SIN1-1. Higher (50-200 nmol) doses of AEA were ineffective and even tended to potentiate the SIN-1 effect. The TRPV1 antagonist capsazepine (CPZ, 30 nmol) prevented SIN-1 effects and attenuated the potentiation of its effect by the higher (200 nmol) AEA dose. The results indicate that AEA can modulate in a dual way the pro-aversive effects of NO in the dIPAG by activating CB1 or TRPV1 receptors. (C) 2012 Elsevier Ltd. All rights reserved.

Minori rumeni tra percorsi migratori e rappresentazioni. Nè soli, nè accompagnati a Bologna

The thesis deals with the heterogenous category of the “unaccompanied minors”, concentrating the scientific work on those who migrate from Romania to the Italian city of Bologna. Between different migratory routes that include Romanian minors, I chose to explore the ones linked with the underground and illegal contexts. In order to analyse the reasons and the morphology of their migratory career, I used the multisituated field research which allowed me to consider the social policies in both the Romanian and the Italian environment. The main debate on the situation of the “unaccompanied children” refers to the extent to which these minors leave their country of origin “accompanied” by different adult figures and it also involves the role played by these adults. The first chapter is dedicated to a brief theoretical and methodological introduction to the main arguments of the thesis such as Romanian migration to Italy, trafficking in human beings, transnationality of migrant’s migration and decentered cooperation as a means of contrasting illegal migration and trafficking. Each field of research is characterized by a specific methodological approach, but they are all linked by the anthropological perspective I adopted throughout the entire work. The Romanian context, analized from a diachronic and a synchronic perspective represents the object of the second chapter. Some aspects of the Regime policies and other characteristics of the Romanian poscomunist period of “transition” are useful frameworks that become a background of the migration flows outside the country. The third chapter focuses on the Romanian patterns of migration. The reconstruction of some past attitudes that Romanians adopted towards migration are relevant in order to reveal the continuity with the present migratory practices. A consistent part is dedicated to a concrete example based on a field research in Bologna on a group of Romanian roma migrating from the south of Romania. The contact with these persons opened a debate on the limits between legal and illegal migration practices among the Romanians. The conclusion is that minors’ migration to Italy follows the adult patterns and flows. The nucleus of the field researches is included in the fourth and the fifth chapter. Before presenting the settings and the itineraries of the field researches, some deconstructive reflections are made on the representations that common sense and social sciences create on concepts as “child”, “minor” and “childhood”. A first perspective on the Romanian migrant minors emerges from a research concentrated on a group of roma teenagers engaged in Bologna in activities like windscreen washing, pocket-picking, begging and street prostitution. The aim of the research was to gain access to their daily life, to observe their relationship with the adults who “accompany” them and the strategies they activate in order to take some material profit out of their migratory experience. A parallel field research focuses on the Romanian minors who are part of the roma group coming from the south of Romania. Most of them are reunited with their family in Bologna, but according to the Italian law, they are all living as illegal migrants. Others are only temporary sheltered by these families and they meanwhile dedicate to illegal survviving practices. An interesting point of my participant observation was to reveal the motivations that these minors give when asked about the refusal to start a legal career inside the local Centres dedicated to the “non accompanied minors”. Their autoreflexivity brings some light on the controversy regarding the adequacy of the local and national care system and the migratory projects the minors have. In this respect, a small part of the research is dedicated to the phenomena of minors’ street prostitution in Bologna, as a useful contribution to the fragmented vision researchers have on the “unaccompanied” or “separated” children. The last chapter focuses on a decentered cooperation project that emerged as an alternative response the local administration from Bologna had chosen for facing the presence of numerous migrants coming from the south of Romania. The group of Romanian roma who was also the object of my field research became the starting point for the cooperation proposals between the city of Bologna and the city of Craiova. Although there are three projects involving the two administrations, throughout a period of stage in the Romanian city of Craiova I chose to analyse, only the one dedicated to the “urgent measures” requested in order to contrast the illegal migration and the trafficking in minors. This final part of the thesis highlightens the possible contribution that such a project might bring to the study of a complex and in some parts contradictory phenomena as that of the “unaccompanied” migrant minors.
