Teoria da despesa pública: uma leitura ético-constitucional em busca do possível da reserva

Brazilian law passes through a crisis of effectiveness commonly attributed to the extravagance of fundamental rights and public shortage. However, public finances are not dogmatically structured to solve the conflicts around the limitations of public spending. There are ethical conditioning factors, like morality, proportionality and impartiality, however, these principles act separately, while the problem of public shortage is holistic. Also, the subjectivity of politics discretionary in the definition of public spending, which is supported in an indeterminate concept of public interest, needs material orientation about the destination of public funds, making it vulnerable to ideological manipulation, resulting in real process of catching rights. Not even the judicial activism (such as influx of constitutionalism) is shown legally appropriate. The Reserve of Possible, also presents basic ethical failure. Understanding the formation of public shortage is therefore essential for understanding the crisis of effectiveness of state responsibilities, given the significant expansion of the state duty of protection, which does not find legal technique of defense of the established interests. The premise of argument, then, part of the possibility of deducting minimal model ethical of desire to spend (public interest) according to objective parameters of the normative system. Public spending has always been treated disdainfully by the Brazilian doctrine, according to the legal character accessory assigned to the monetary cost. Nonetheless, it is the meeting point between economics and law, or is in the marrow of the problem of public shortage. Expensive Subjects to modernity, as the effectiveness of fundamental rights, pass necessarily an ethical legal system of public spending. From the ethical principles deducted from the planning, only the democratic principle guides the public spending through the approval of public spending in the complex budget process. In other words, there is an ethical distancing of economic reality in relation to state responsibilities. From the dogmatic belief of insufficiency, public spending is evaluated ethically, according to the foundations of modern constitutionalism, in search of possible of the financial reserve, certain that the ethics of public economy is a sine qua non condition for legal ethics.

Avaliação mesoscópica da origem, distribuição e ramificação do nervo radial no braço do gato doméstico (Felis catus domesticus, Linnaeus, 1758)

The present study evaluated the origin, distribution and ramification of the radial nerves were studied in 30 adult domestic cats. The sample included 15 females and 15 males of unknown breed. The specimens were fixed in 10% formaldehyde solution. The radial nerve showed many fascicles from the origin also your ramification in superficial and deep branches. Radial nerves were observed to originate, in 16 cases (26.7%), from the ventral branch of the sixth cervical spinal nerve; in 60 cases (100%), from the ventral branch of the seventh cervical spinal nerve; in 60 cases (100%), from the ventral branch of the eight cervical nerve and in 60 cases (100%), from the ventral branch of the first thoracic nerve. The radial nerves branched out, in all of the animals studied (100.0%), to the tensor fasciae antebrachii, long, accessory, medial and lateral heads of the triceps branchii and anconeus muscles. The radial nerve emits of 14 to 25 nervous branches in this region. However, the branch of the sixth cervical spinal nerve and the nervous fascicles reveal significant differences (p <= 0.05), respectively, in or with relation to sex of the animals and the studied region.

Lesão por esmagamento do nervo isquiático de ratos: estudo da vascularização

Este trabalho teve como objetivo estudar as alterações microvasculares intraneurais aguda em nervo isquiático de rato submetido a esmagamento por diferentes cargas. Foram utilizados 60 ratos machos da linhagem Wistar, distribuídos em grupos experimentais de acordo com a injeção de vasos e com a carga de esmagamento. Os nervos isquiáticos direitos foram isolados e submetidos ao esmagamento com cargas (0,5 Kg, 1 Kg, 5 Kg, 10 kg e 15 kg) por 10 minutos e os nervos isquiáticos esquerdos foram utilizados como controle. Após esmagamento, os animais foram submetidos à cateterização da aorta abdominal e injeção dos vasos, em seguida 30 nervos direitos e esquerdos foram fixados em formol 10%, desidratados e diafanizados para análise longitudinal dos vasos intraneurais e os restantes retirados em toda a sua extensão, cortados em 3 fragmentos, congelados em isopentano em gelo seco e armazenados em freezer -70°C, seccionados transversalmente para análise e contagem dos vasos intraneurais. As análises macroscópica e microscópica mostraram regiões de hematoma endoneural e epineural nas diferentes cargas de esmagamento. A análise morfométrica sugere que a lesão aos vasos intraneurais foi proporcional à carga de esmagamento, causando hematoma endoneural e epineural, que cria microambiente desfavorável para a regeneração das fibras nervosas.

Plasticidade de células tronco mesenquimais de medula óssea de ratos na presença de meio condicionado do nervo facial e do fator de crescimento fibroblástico 2

A number of evidences show the influence of the growth of injured nerve fibers in Peripheral Nervous System (PNS) as well as potential implant stem cells (SCs) to make it more suitable for nerve regeneration medium. In this perspective, this study aimed to evaluate the plasticity of mesenchymal stem cells from bone marrow of mice in the presence of culture medium conditioned with facial nerve explants (D-10) and fibroblast growth factor-2 (FGF-2). In this perspective, the cells were cultivated only with DMEM (group 1), only with D-10(group 2), only with FGF-2(group 3) or with D-10 and FGF-2(group 4). The growth and morphology were assessed over 72 hours. Quantitative phenotypic analysis was taken from the immunocytochemistry for GFAP, OX-42, MAP-2, β-tubulin III, NeuN and NF-200 on the fourth day of cultivation. Cells cultured with conditioned medium alone or combined with FGF-2 showed distinct morphological features similar apparent at certain times with neurons and glial cells and a significant proliferative activity in groups 2 and 4 throughout the days. Cells cultived only with conditioned medium acquired a glial phenotype. Cells cultured with FGF-2 and conditioned medium expressed GFAP, OX-42, MAP-2, β-tubulin III, NeuN and NF-200. On average, area and perimeter fo the group of cells positive for GFAP and the área of the cells immunostained for OX-42 were higher than those of the group 4. This study enabled the plasticity of mesenchymal cells (MCs) in neuronal and glial nineage and opened prospects for the search with cell therapy and transdifferentiation

Processo argumentativo na (re)significação de concepções ético/morais

This study analysed the relationship between the production of argumentative discourses and the development and (re)signification of ethical/moral concepts, conceptions and reasoning. It focused on ethical-argumentative reasoning concerning other people and their different points of view. The specific aims of this research were: (1) to investigate the considering alternative positions on adolescents previous views on a specific topic; (2) to verify whether the ability to generate counterarguments was associated with higher levels of moral reasoning, according to Kohlberg theory, and (3) to have a better comprehension of a possible relationship between adolescents abilities to use cognitive and verbal-argumentative strategies and the (re) signification of concepts/beliefs of an ethical/moral nature, and also the solution of conflicts of the same nature. The participants in this study were seventh grade students of private and public schools. Four empirical tasks were used in order to evaluate argumentative and moral reasoning. These tasks focused on: the evaluation of moral dilemmas (DIT); the evaluation of moral dilemmas with the presentation of a written justification for subjects responses; the production of arguments and the reaction to counterarguments. There was also a group-debate situation in which both argumentation and the discussion ethical/moral issues were observed. The moral dilemmas tasks aimed to evaluate the level of moral reasoning of the participants. The argumentation tasks investigated whether the adolescents generated and justified a point of view and how they dealt with counterarguments or alternative information which could lead the participants to modify their initial positions on the topic under discussion in a monological situation as well as in a group-debate setting. The results showed that, in a monological situation, most of the adolescents produced only a partial developed argumentative discourse, whereas in a more social-verbal interaction situation their discourse appeared to be more elaborated. As a general result, it was observed that the confrontation with the other s views, or dealing with counterarguments allow the adolescents to re-evaluate and re-elaborate their own views on a debatable topic. Regarding the relationship between counterargumentation and moral reasoning, it was verified that there was a subtle tendency associating the two processes. However, other factors, such as, social, emotional and cultural aspects might also influence the development of moral reasoning

Instrumentalidade do serviço social: dimensões teórico-metodológica, ético-política e técnico-operativa e exercício profissional

The dissertation proposes a discussion about the instrumentality of the Social Work, in the attempt of visualizing her, as well as the profession, in a totality perspective to the light of the rationality critical-dialetical. Understood as the capacity that the professional subjects acquire of giving answers to the demands that are placed to the profession, itself built partner-historically, in a teleologys conflicts and causalitys. So, it is proposed the discussion of the instrumentality while a group of you know specific, composed essentially by the development of three practical-formative dimensions. The theoretical-methodological refers to the capacity of apprehension of the method and of the theories and, consequently, of the relationship that does with the practice. The dimension ethical-politics concerns the development of the capacity of analyzing the society and the own profession as field of contradictory forces, being considered the character eminently political of the professional exercise, as well as the professional's conscience concerning the social direction that prints in your intervention. And the technician-operative dimension refers more strictly to the technical elements and you score for the development of the intervention. It was looked for to evidence as those dimensions they attend in the professional exercise, starting from the experience lived by the social workers of the Social Attendance Reference Centers, in Natal/RN

Serviço Social Audit Saúde no SUS/RN: projeto ético político profissional e de reforma sanitária

Health policies in Brazil, the decentralization of SUS management responsibilities for the three spheres of government has driven the creation and regulation of the audits of health services in the National Audit Office, this is a trend of neoliberal policies imposed by international bodies like the World Bank and IMF to peripheral countries characterized by productive restructuring and reforming the state focuses on the presence of two competing projects in the area of health: Health Sector Reform Project which is based on the democratic rule of law with the assumption of health as social right and duty of the State in defending the extension of the conquest of rights and democratization of access to health care guaranteed through the public financing strategies and the effective decentralization of decisions pervaded by social control and privatized Health Project which is based on the state minimum, with a reduction in social spending or in partnerships and privatization, stronger nonprofit sector, subject to capitalist interests, is made effective through strategies targeting health policy and refilantropização actions. In this context, the present study is an analysis on the work of social audits of public health in infants from a qualitative and quantitative approach, embodied by the critical method of dialectical Marxist social theory that enabled us to unveil the characterization, the demands, challenges and outline the profile of Social Work in teams inserted audits of SUS in RN, but also provided evidence to demonstrate the prospects and possibilities of this area of activity of social workers. It was also found that through the audit work that the state fulfill its role as bureaucratic and regulator of health services with efficiency, effectiveness and economy. Yet, paradoxically, the audits of SUS may provide a vehicle for enforcing rights and ensuring the fundamental principles contained in the project of health reform, because it can be configured in a space of political struggle as representing a new field of knowledge production that needs to be appropriate for a theoretical critic able to redirect the social interests in favor of the user. From this perspective, it is concluded that the work of social audits of public health in infants despite the social relevance that prints, as they constitute an activity study of reality and its transformation proposition requires a transformative political action guided the discussion Marxist theory holds that the ethical project professional politician of Social Work

Análise morfométrica e ultra-estrutural do nervo óptico de ratos induzidos a ingestão de álcool

OBJETIVO: Analisar os efeitos da ingestão crônica de álcool sobre o nervo óptico em um modelo murino adulto. MÉTODOS: Doze ratos machos da raça Wistar, de 30 dias de idade, foram divididos por sorteio em 2 grupos experimentais: tratado (TG), com 8 animais, alimentados com ração-padrão para roedores de laboratório e uma mistura de água de torneira e etanol ad libitum; controle (CG), com 4 animais, alimentados com a mesma ração e água de torneira pura ad libitum. Após 40 semanas todos os ratos foram sacrificados, sendo os nervos ópticos de ambos os olhos preparados para microscopia óptica e eletrônica. A área de secção transversal de cada nervo a aumento de 500´, assim como número de fibras axonais dentro de 5 campos aleatoriamente selecionados a aumento de 2000´ foram medidos com auxílio de digitalizador de imagens acoplado ao microscópio óptico. Foram realizadas fotomicrografias de 10 campos aleatoriamente selecionados de cada nervo (5 centrais e 5 periféricos) a aumento de 4200´ em microscópio eletrônico de transmissão. RESULTADOS: A análise morfométrica não mostrou diferenças estatisticamente significativas entre os 2 grupos estudados. em contraste com o CG, o exame ultra-estrutural dos nervos ópticos do TG mostrou um intenso desarranjo das bainhas de mielina, que se tornaram espessadas, com separação de suas lamelas, apresentando, por vezes, degenerações interlamelares elétron-densas, além da presença de muitas organelas degeneradas. CONCLUSÃO: Os achados desse estudo mostram alterações ultra-estruturais no nervo óptico de ratos adultos após ingestão crônica de álcool, sem modificações morfométricas significativas.

Bloqueio do nervo alveolar mandibular com ropivacaína a 0,5 % em gatos

Objetivou-se, com este experimento, avaliar a ação da ropivacaína a 0,5% no bloqueio do nervo alveolar mandibular de gatos. Vinte gatos adultos, sem raça definida, machos ou fêmeas, receberam clorpromazina (1,0mg kg-1, VO) e propofol (3,0mg kg-1, IV). Ropivacaína a 0,5% foi administrada com uma agulha 13x3,8 em forma de L, inserida no ângulo da mandíbula direita, aproximadamente 1,0cm rostral ao processo angular e 0,5cm dorsal à superfície medial do ramo da mandíbula, a fim de depositá-la próximo ao nervo alveolar mandibular, no forame mandibular. As freqüências cardíaca e respiratória foram mensuradas antes da administração da clorpromazina, 20 minutos após administração desta (T0), 20 minutos após o bloqueio do nervo alveolar mandibular com ropivacaína (T20) e, em intervalos de 20 minutos, até a volta da sensibilidade na região anestesiada. Observou-se o período de latência e a duração da anestesia por meio do pinçamento da pele e gengiva da região lateral direita da mandíbula. Encontrou-se início da anestesia após 22 minutos, com duração de 164,25 minutos. Os parâmetros de freqüência cardíaca e freqüência respiratória tiveram alterações, porém sem significado clínico para a espécie. A ropivacaína a 0,5% anestesia a região dos dentes pré-molares, molares, caninos, incisivos, pele e mucosa oral e lábio inferior, sem causar efeitos colaterais.

Efeito analgésico de longa duração da dipirona sobre a hiperalgesia persistente induzida pela constrição do nervo ciático em ratos: participação do óxido nítrico

Estudo das relações anatômicas e suas variações entre o nervo ciático e o músculo piriforme

CONTEXTO: A síndrome do músculo piriforme pode ter como causa a passagem anormal do nervo ciático ou de uma de suas partes pelo ventre do músculo piriforme. OBJETIVO: Analisar as relações anatômicas e métricas entre o músculo piriforme e o nervo ciático, contribuindo com o conhecimento anátomo-clínico da região glútea. MÉTODO: Foram utilizados 20 cadáveres adultos de ambos os sexos. O nervo ciático e o músculo piriforme foram dissecados, medidos e fotodocumentados. RESULTADOS: Observou-se que 85% das 40 regiões glúteas apresentaram o nervo como tronco único, passando pela borda inferior do músculo piriforme, e 15% mostraram uma variação bilateral, caracterizada pela passagem do nervo fibular comum através do músculo piriforme. Os dados obtidos não revelaram diferenças estatisticamente significantes.

ESTUDO DO EFEITO DE GANGLIOSIDEOS EXOGENOS NA REGENERACAO NERVOSA APOS COMPRESSAO E NEURORRAFIA NO NERVO CIATICO DO RATO

The authors studied the possible inductive effect of exogenous gangliosides administrated intra-peritoneal and intra-muscular, in 33 rats, after compression and sutures of sciatic nerve. In the animals suffering compression of the sciatic nerve only, the myelin sheath was preserved with good regeneration of the nerve. There was no statistics difference between the two groups with or without the administration of gangliosides. In the group of rats where section of the sciatic nerve and suture were performed, neuroma of amputation as well as dense cicatricial tissue with inflammatory reaction of foreign body type was noted around the sutures. In conclusion, the formation of neuroma of amputation associated with severe inflammatory reaction had an important role in determining the regeneration of the nerve.
