Nanoparticulas magnéticas de óxido de ferro tem sido amplamente utilizadas em diversas áreas da biotecnologia e biomedicina, tais como no tratamento de câncer, marcação de célula e como agentes de contraste em imagem por ressonância magnética. O intuito deste trabalho foi sintetizar as nanopartículas magnéticas com magnetização de saturação intensificadas via processo do poliol modificado, e usando agentes de superfície para melhorar as propriedades de superfície. Carboximetildextrana, metilpolietilenoglicol (MPEG), quitosana, sílica e 3-aminopropiltrimetoxisilano (APTMS) foram utilizados para a modificação da superfície. Através da microscopia eletrônica de transmissão (TEM), foi obtido que as nanopartículas magnéticas de magnetita obtiveram um diâmetro médio de 5nm, em uma estreita distribuição de tamanho. A difração de raios-X (DRX) indicou a formação de magnetita em todos os sistemas em que o método do poliol modificado foi utilizado. As medidas de espectroscopia no infravermelho (FTIR) evidenciaram a presença de modos de vibração relacionados às macromoléculas e compostos inorgânicos utilizados na modificação de superfície das nanopartículas magnéticas. A TEM das diferentes modificações de superfície mostram a formação de aglomerados dependendo do modificador utilizado. As nanopartículas recobertas com APTMS foram funcionalizadas com ácido fólico...

The purpose of this study is to chart academic output on vague and diffuse symptoms in biomedicine. As methodological tool, we conducted a bibliographic study through the Internet ranging from 1990 to 2005. Forty papers were selected and five major theme areas were established for the survey: the nomenclatures assigned to vague and diffuse symptoms; their definitions; the relevance of the theme being addressed; the criteria used to diagnose vague and diffuse symptoms; and the therapeutic actions adopted. The discussion of the findings identifies many biomedical difficulties in dealing with sufferers from undefined complaints, including: diversity and lack of conceptual precision in the use of the nomenclature; physicians who are poorly prepared to deal with these patients; demand considered as a psychic disorder; difficulties in establishing diagnostic criteria and poor use of treatment resources. This leads to the conclusion that the biomedical model behind these difficulties has few tools for dealing with the singularities of human suffering and its experiential phenomenological dimension.

Photoacoustics has been broadly studied in biomedicine, for both human and small animal tissues. Photoacoustics uniquely combines the absorption contrast of light or radio frequency waves with ultrasound resolution. Moreover, it is non-ionizing and non-invasive, and is the fastest growing new biomedical method, with clinical applications on the way. This article provides a brief review of recent developments in photoacoustics in biomedicine, from basic principles to applications. The emphasized areas include the new imaging modalities, hybrid detection methods, photoacoustic contrast agents, and the photoacoustic Doppler effect, as well as translational research topics.

During the past four decades, Oman has transformed into a modern state with remarkable changes in all fields, including public health and the provision of medical services. Little attention has been paid so far to the history of the development of biomedicine in Oman. A history of healing practices, just like clinical patient histories, helps to diagnose problems, plan interventions and predict their future within a dynamic context. This study is the first to explore the beginnings and evolution of biomedicine in Oman during the 19th century, categorising it into three eras: from the casual system offered by occasional visiting biomedical practitioners to the more organised, but limited, British military hospital and, finally, to public missionary medical care toward the end of the 19th century. The study concludes by recommending further focus on medical humanities, including the history of medicine, as a contributing factor to improve and sustain the art and practice of medicine within the existing Omani health care system.

Medical ethics as a scholarly discipline and a system of moral principles that apply values and judgments to the practice of medicine encompasses its practical application in clinical settings as well as work on its history, philosophy, theology, anthropology and sociology. As such there are a number of values in medical ethics such as autonomy, non-maleficence, confidentiality, dignity, honesty, justice and beneficence, among others. These values act as guidelines for professionals in the medical fraternity and are therefore used to judge different cases in the fraternity. For purposes of this work, this paper examines the principle of beneficence in biomedicine. Using both hypothetical cases and others in real life situations, the paper reflects on the implications of beneficence in biomedicine. It argues that the principle of beneficence is a prima facie obligation that should “always be acted upon unless it conflicts on a particular occasion with an equal or stronger principle”.

The rise of anti-ageing medicine is emblematic of the current conditions of American biomedicine. Through in-depth interviews with 31 anti-ageing practitioners, we examine how practitioners strive for—and justify—a model of care that runs counter to what they see as the ‘assembly line’ insurance-managed industry of healthcare. Their motivation, however, is not merely a reaction to conventional medicine. It is derived from what they see as a set of core beliefs about the role of the physician, the nature of the physician-patient relationship, and the function of biomedicine. We analyse this ideology to underscore how anti-ageing medicine is built on a ‘technology of the self’, a self in need of constant surveillance, intervention, and maintenance. The ultimate goal is to create an optimal self, not just a self free of illness. A fundamental irony is that, despite their self-presentation and the perception of the public, anti-ageing providers do not use practices that are especially ‘high-tech’ or unconventional. Instead, the management of ageing bodies rests on providers’ perceived knowledge of their patients, tailored treatments, and a collaborative pact between the provider and patient.

Due to finite size effects, such as the high surface-to-volume ratio and different crystal structures, magnetic nanoparticles are found to exhibit interesting and considerably different magnetic properties than those found in their corresponding bulk materials. These nanoparticles can be synthesized in several ways (e.g., chemical and physical) with controllable sizes enabling their comparison to biological organisms from cells (10–100 μm), viruses, genes, down to proteins (3–50 nm). The optimization of the nanoparticles’ size, size distribution, agglomeration, coating, and shapes along with their unique magnetic properties prompted the application of nanoparticles of this type in diverse fields. Biomedicine is one of these fields where intensive research is currently being conducted. In this review, we will discuss the magnetic properties of nanoparticles which are directly related to their applications in biomedicine. We will focus mainly on surface effects and ferrite nanoparticles, and on one diagnostic application of magnetic nanoparticles as magnetic resonance imaging contrast agents.

The use of nanotechnology in biomedicine involves the engineering of nanomaterials to act as therapeutic carriers, targeting agents and diagnostic imaging devices. The application of nanotechnology in cancer aims to transform early detection, targeted therapeutics and cancer prevention and control. To assist in expediting and validating the use of nanomaterials in biomedicine, the National Cancer Institute (NCI) Center for Biomedical Informatics and Information Technology, in collaboration with the NCI Alliance for Nanotechnology in Cancer (Alliance), has developed a data sharing portal called caNanoLab. caNanoLab provides access to experimental and literature curated data from the NCI Nanotechnology Characterization Laboratory, the Alliance and the greater cancer nanotechnology community.

Pleiotropy arises when a locus influences multiple traits. Rich GWAS findings of various traits in the past decade reveal many examples of this phenomenon, suggesting the wide existence of pleiotropic effects. What underlies this phenomenon is the biological connection among seemingly unrelated traits/diseases. Characterizing the molecular mechanisms of pleiotropy not only helps to explain the relationship between diseases, but may also contribute to novel insights concerning the pathological mechanism of each specific disease, leading to better disease prevention, diagnosis and treatment. However, most pleiotropic effects remain elusive because their functional roles have not been systematically examined. A systematic investigation requires availability of qualified measurements at multilayered biological processes (e.g., transcription and translation). The rise of Big Data in biomedicine, such as high-quality multi-omics data, biomedical imaging data and electronic medical records of patients, offers us an unprecedented opportunity to investigate pleiotropy. There will be a great need of computationally efficient and statistically rigorous methods for integrative analysis of these Big Data in biomedicine. In this review, we outline many opportunities and challenges in methodology developments for systematic analysis of pleiotropy...

Background: The National Institutes of Health (NIH) Roadmap places special emphasis on “bench-to-bedside” research, or the “translation” of basic science research into practical clinical applications. The Clinical and Translational Science Awards (CTSA) Consortium is one example of the large investments being made to develop a national infrastructure to support translational science, which involves reducing regulatory burdens, launching new educational initiatives, and forming partnerships between academia and industry. However, while numerous definitions have been suggested for translational science, including the qualitative T1-T4 classification, a consensus has not yet been reached. This makes it challenging to tract the impact of these major policy changes. Methods: In this study, we use a bibliometric approach to map PubMed articles onto a graph, called the Triangle of Biomedicine. The corners of the triangle represent research related to animals, cells and molecules, and humans; and, the position of a publication on the graph is based on its topics, as determined by its Medical Subject Headings (MeSH). We define translation as movement of a collection of articles, or the articles that cite those articles, towards the human corner. Results: The Triangle of Biomedicine provides a quantitative way of determining if an individual scientist...

The original publication is available at www.springerlink.com [http://www.springerlink.com/content/0138-9130]; The effects of team consolidation and social integration on individual scientists’ activity and performance were investigated by analysing the relationships between these factors and scientists’ productivity, impact, collaboration patterns, participation in funded research projects and programs, contribution to the training of junior researchers, and prestige. Data were obtained from a survey of researchers ascribed to the Biology and Biomedicine area of the Spanish Council for Scientific Research, and from their curricula vitae. The results show that high levels of team consolidation and of integration of the scientist within his or her team are factors which might help create the most favourable social climate for research performance and productivity. Researchers who carried out their activity in a social climate characterized by these factors participated in more domestic research projects and supervised more doctoral dissertations than the rest of their colleagues.

This paper aims to examine the rise and the fall of biomedicine in the public legitimization of the development of nuclear energy. Until the late 1950s, biological and medical applications of radioisotopes were presented as the most important successes of the peaceful uses of atomic energy. I will argue that despite the major financial investment, the development of the uses of radioisotopes and their important impact on biology and clinical practices, the assessment of medical uses remained relatively limited. As consequence, the place of biomedicine in the public legitimization of financial investment and civilian uses of nuclear energy began to decline from the late 1950s.
