Profissionais da área da saúde: conhecimento e terminologia de documentação

A interação dos profissionais das áreas da saúde e de informação permitirá não só consolidar o processo de comunicação, mas também agilizar as várias etapas da geração de novos conhecimentos. Para isso, é necessário dominar a terminologia considerada básica para compreender o fluxo de comunicação e os termos essenciais ao acesso à informação, quer pelo processo manual e/ou automatizado. Os resultados alcançados em uma pesquisa realizada com uma comunidade da área de saúde permitiram a adoção de estratégias que iriam facilitar a preparação desses pesquisadores para participar das etapas posteriores de pesquisa mais abrangente, que está sendo efetuada para implantação de um "Centro de Informação e Documentação". Foram comparadas as respostas da comunidade da área da saúde com as de uma elite selecionada de uma comunidade da área tecnológica.

Interfaces e organização da pesquisa no Brasil: da Química à Nanotecnologia

Nanotechnology can be viewed as a powerful tool, capable of shaping the chemistry of atoms and molecules, converting them into exciting nanosized and nanostructured materials, devices and machines. However, in pursuing this task, an exceptional ability is required to deal with complex inter- and multidisciplinary approaches, as imposed by the nanoscale. A new research organization framework, capable of promoting cooperative interactions in many complementary areas, including the industries, is demanded. In this sense, an interesting example are the nanotechnology networks and millenium institutes recently created in Brazil. The highlights and weakness of such cooperative research networks are discussed, in addition to relevant nanotechnology themes focusing on the special needs and resources from the developing nations.

Estratégia supramolecular para a nanotecnologia

Brazilian science is evolving rapidly and steadly in the last 10 years, reaching the 15º place in the international ranking. Research in nanotechnology is following a similar way generating new scientific and technological knowledge in several frontiers but specially in the interfaces of two or more areas, where Chemistry is consolidating itself as a central science. In this context, the supramolecular approach is a very promissing one because it allows the build-up of a chemical inteligence using all the sistematized knowledge for the design and development of new nanomaterials and products. The great challenge of Chemistry is not decrease the dimensionality of the materials but instead find ways to increase the dimensionality and structural complexity keeping strict control on the interactions between the components, in order to generate materials with new properties and functionalities. Unfortunately, the current vigorous advancement of scientific research has not been followed by the transformation of such know-how into patents and produts. Therefore much efforts should be devoted to build a national science and technology program, joining all the segments of the society involved in the technological development (university, institutes of technological research, industry and government) in order to promote the furtherance of the Brazilian technological base. Only in this way it is possible to evolve to a technological society capable to transform the scientific knowledge into wealthy, thus sustaining the socioeconomic development of the country.

Um panorama da nanotecnologia no Brasil (e seus macro-desafios)

The objectives of this essay are to describe the development of nanoscience and nanotechnology (N&N) in Brazil. The analysis shows that Brazilian research in N&N is considered satisfactory and, although under other denominations, dates from at least 20 years. Innovation is still less satisfactory and there are different points of views on the issue. However, there is already a tendency towards the promotion of innovation in nanotechnology in the country. Scientists and the industrial sector have been showing interest in partnerships and some scientific policies stimulate this articulation between academy and companies.

Nanotecnologia: aspectos gerais e potencial de aplicação em catálise

In recent years nanomaterials, such as metallic nanoparticles, nanowires, nanotapes, nanotubes and nanocomposites, have attracted increasing interest for several technological applications. In catalysis, the great potential of nanomaterials is related to the high catalytic activity exhibited by these materials as a function of the high surface/volume ratio when the particles acquire diameter below 5 nm. In this work, a review about concepts and background of nanoscience and nanotechnology is presented with emphasis in catalysis. Special attention is given to gold nanoparticles and carbon nanotubes, focusing the properties and characteristics of these materials in several catalytic reactions.

There were obtained 1352 patent applications in this period. It were analyzed the legal nature of the depositors, the year of deposit, depositors' home countries and processes. It has been a goal subsidizes the policy-makers to adapt and modernize the regulatory framework on nanotechnology and risks involving health as a strategic area in the politics of Science.

Impactos da nanotecnologia na saúde: produção de medicamentos

Several studies have described the benefits of nanoscience and nanotechnology (N&N) in different sectors such as agriculture, energy, environmental preservation, and public health. The rapid evolution of N&N can be shown through a panoramic analysis of scientific papers and patents. In the area of public health, it is estimated that the global market for nanotechnology products will expand to 160 billion U.S. dollars in 2015. The Brazilian government has also strengthened its innovative potential in N&N through economic subsidies, as observed for other countries. This review is focused on the current landscape of N&N in a therapeutic context, highlighting the development of nanotech-products produced with biocompatible and biodegradable materials that are already commercially available or under investigation. Most studies under investigation are focused on the development of nanotechnology-based formulations intended for treatment of cancer, inflammatory, cardiovascular, and neurological diseases. Although there are several advantages of N&N in healthcare, many challenges have to be conquered to increase the availability of nanotechnology products in toxicological, preclinical and clinical studies, scale-up, regulatory, and private investments.

Nanotecnologia em medicina: aspectos fundamentais e principais preocupações

The recent advances in the development of nanomaterials have opened new and exciting opportunities for their applications in medicine. These applications include molecular imaging, drug-delivery, and photothermal therapy. Despite the progress in medicinal applications of nanomaterials, several key problems remain unaddressed. Recent advances in this area include the enhancement of sensitivity in early diagnosis and therapy, in addition to investigations into the possible toxicity of nanomaterials. However, since little is known about the toxicity of nanomaterials, the regulation of these materials is a slow and complex process. This paper reviews the current scenario in the applications of nanomaterials in medicine as well as the main concerns and regulatory questions.
