Towards Humane Technologies: Biotechnologies, New Media and Ethics

What are the ethical and political implications when the very foundations of life —things of awe and spiritual significance — are translated into products accessible to few people? This book critically analyses this historic recontextualisation. Through mediation — when meaning moves ‘from one text to another, from one discourse to another’ — biotechnology is transformed into analysable data and into public discourses. The unique book links biotechnology with media and citizenship. As with any ‘commodity’, biological products have been commodified. Because enormous speculative investment rests on this, risk will be understated and benefit will be overstated. Benefits will be unfairly distributed. Already, the bioprospecting of Southern megadiverse nations, legally sanctioned by U.S. property rights conventions, has led to wealth and health benefits in the North. Crucial to this development are biotechnological discourses that shift meanings from a “language of life” into technocratic discourses, infused with neo-liberal economic assumptions that promise progress and benefits for all. Crucial in this is the mass media’s representation of biotechnology for an audience with poor scientific literacy. Yet, even apparently benign biotechnology spawned by the Human Genome Project such as prenatal screening has eugenic possibilities, and genetic codes for illness are eagerly sought by insurance companies seeking to exclude certain people. These issues raise important questions about a citizenship that is founded on moral responsibility for the wellbeing of society now and into the future. After all, biotechnology is very much concerned with the essence of life itself. This book provides a space for alternative and dissident voices beyond the hype that surrounds biotechnology.

A QUM partnership approach to regulating biosimilars in Australia

Despite the realisation of the potential implications from biosimilars is relatively recent, much has already been written about raising the awareness of differences between biosimilars and originating/ reference listed (innovator) pharmaceuticals. The European Medicines Agency has led the global charge in regulating biosimilars. Regardless of sufficient similarities across international regulations, differences do exist across jurisdictions. The consideration of regulating biosimilars demands a congruent approach across all stages: pre-registration (Australian copyright protection, patent, international obligations), registration (confidential information, international regulators, safety and efficacy), post-registration (Pharmaceutical Benefit Scheme, prescriber and dispenser awareness). Our National Medicines Policy could provide the necessary congruent framework and function for national and international regulation of biosimilars. The Policy concedes that pharmaceuticals will be affected by financial policies and trade considerations, international treaty obligations, industrial policies, education policies and the need for public-private partnerships.

Entry and competition in generic biologics

Patents for several blockbuster biological products are expected to expire soon. The Food and Drug Administration is examining whether biologies can and should be treated like pharmaceuticals with regard to generics. In contrast with pharmaceuticals, which are manufactured through chemical synthesis, biologies are manufactured through fermentation, a process that is more variable and costly. Regulators might require extensive clinical testing of generic biologies to demonstrate equivalence to the branded product. The focus of the debate on generic biologies has been on legal and health concerns, but there are important economic implications. We combine a theoretical model of generic biologies with regression estimates from generic pharmaceuticals to estimate market entry and prices in the generic biologic market. We find that generic biologies will have high fixed costs from clinical testing and from manufacturing, so there will be less entry than would be expected for generic pharmaceuticals. With fewer generic competitors, generic biologies will be relatively close in price to branded biologies. Policy makers should be prudent in estimating financial benefits of generic biologies for consumers and payers. We also examine possible government strategies to promote generic competition.

The International Symposium on Fungal Stress - ISFUS

Fungi play central roles in many biological processes, influencing soil fertility, decomposition, cycling of minerals, and organic matter, plant health, and nutrition. They produce a wide spectrum of molecules, which are exploited in a range of industrial processes to manufacture foods, food preservatives, flavoring agents, and other useful biological products. Fungi can also be used as biological control agents of microbial pathogens, nematodes or insect pests, and affect plant growth, stress tolerance, and nutrient acquisition. Successful exploitation of fungi requires better understanding of the mechanisms that fungi use to cope with stress as well as the way in which they mediate stress tolerance in other organisms. It is against this backdrop that a scientific meeting on fungal stress was held in São José dos Campos, Brazil, in October 2014. The meeting, hosted by Drauzio E. N. Rangel and Alene E. Alder-Rangel, and supported by the São Paulo Research Foundation (FAPESP), brought together more than 30 young, mid-career, and highly accomplished scientists from ten different countries. Here we summarize the highlights of the meeting.

Production of lipase by extractive fermentation with ionic liquids

Novos processos fermentativos, designados por processos de Fermentação Extractiva, são caracterizados por apresentarem etapas de produção e extracção em simultâneo. A extracção líquido-líquido como técnica de separação é amplamente usado na indústria química pela sua simplicidade, baixo custo e facilidade de extrapolação de escala. No entanto o uso de solventes orgânicos nestes processos potencia os riscos ocupacionais e ambientais. Neste contexto, o uso de sistemas de duas fases aquosas baseados em líquidos iónicos, apresenta-se como uma técnica eficaz para a separação e purificação de produtos biológicos. Este trabalho apresenta um estudo integrado sobre o uso de líquidos iónicos não aromáticos foram determinados. A capacidade para a formação de sistemas de duas fases foi estudada para uma vasta gama de líquidos iónicos hidrofílicos com diferentes aniões, catiões e cadeias alqúilicas. A capacidade de separação e purificação de um largo conjunto de líquidos iónicos foi posteriormente investigada, recorrendo-se ao uso de várias biomoléculas modelo de diferentes graus de complexidade, um amino-acido (L-triptofano) e duas enzimas lipolíticas (enzima produzida pela bactéria Bacillus sp. e Candida antarctica lipase B – CaLB). Esta última foi ainda usada para um estudo de biocompatibilidade, tendo sido determinado o efeito de diferentes LIs hidrofílicos na sua actividade enzimática. Este trabalho mostra um estudo ecotoxicológico duma vasta gama de líquidos iónicos e espécies aquáticas, inseridas em diversos níveis tróficos. A bioacumulação foi investigada através do estudo dos coeficientes de distribuição 1-octanol-água (Dow).

A tale of two bioprocesses

Bioprocesses use microorganisms or cells in order to produce and/or obtain some desired products. Nowadays these strategies appear as a fundamental alternative to the traditional chemical processes. Amongst the many advantages associated to their use in the chemical, oil or pharmaceutical industries, their low cost, easily scale-up and low environmental impact should be highlighted. This work reports two examples of bioprocesses as alternatives to traditional chemical processes used by the oil and pharmaceutical industries. In the first part of this work it was studied an example of a bioprocess based on the use of microorganisms in enhanced oil recovery. Currently, due to high costs of oil and its scarcity, the enhanced oil recovery techniques become very attractive. Between the available techniques the use of microbial enhanced oil recovery (MEOR) has been highlighted. This process is based on the stimulation of indigenous microorganisms or by the injection of microorganism consortia to produce specific metabolites and hence increase the amount of oil recovered. In the first chapters of this work the isolation of several microorganisms from samples of paraffinic Brazilian oils is described, and their tensioactive and biodegradability properties are presented. Furthermore, the chemical structures of the biosurfactants produced by those isolates were also characterized. In the final chapter of the first part, the capabilities of some isolated bacteria to enhance the oil recovery of paraffinic Brazilian oils entrapped in sand-pack columns were evaluated. In the second part of this work it was investigated aqueous two-phase systems or aqueous biphasic systems (ABS) as extractive strategies for antibiotics directly from the fermented broth in which they are produced. To this goal, several aqueous two-phase systems composed of ionic liquids (ILs) and polymers were studied for the first time and their phase diagrams were determined. The novel ATPS appear as effective and economic methods to extract different biomolecules or/and biological products. Thus, aiming the initial antibiotics extraction purpose it was studied the influence of a wide range of ILs and polymers in the aqueous two-phase formation ability, as well as their influence in the partitioning of several type-molecules, such as amino acids, alkaloids and dyes. As a final chapter it is presented the capacity of these novel systems to extract the antibiotic tetracycline directly from the fermented broth of Streptomyces aureofaciens.

Light harvesting in solar cells using natural pigments from red fruits adsorbed to mesoporous TiO2

Nature has developed strategies to present us with a wide variety of colours, from the green of leaves to the bright colours seen in flowers. Anthocyanins are between these natural pigments that are responsible for the great diversity of colours seen in flowers and fruits. Anthocyanins have been used to sensitize titanium dioxide (TiO2) in Dye-Sensitized Solar Cells (DSSCs). DSSCs have become one of the most popular research topic in photovoltaic cells due to their low production costs when compared to other alternatives. DSSCs are inspired in what happens in nature during photosynthesis. A primary charge separation is achieved by means of a photoexcited dye capable of performing the electron injection into the conduction band of a wide band-gap semiconductor, usually TiO2. With this work we aimed to synthesize a novel mesoporous TiO2 structure as the semiconductor in order to increase the dye loading. We used natural occurring dyes such as anthocyanins and their synthetic flavylium relatives, as an alternative to the widely used metal complexes of Ru(II) which are expensive and are environmentally unsafe. This offers not only the chance to use safer dyes for DSSCs, but also to take profit of waste biological products, such as wine and olive oil production residues that are heavily loaded with anthocyanin dyes. We also performed a photodegradation study using TiO2 as the catalyst to degrade dye contaminants, such as those from the wine production waste, by photo-irradiation of the system in the visible region of the light spectrum. We were able to succeed in the synthesis of mesoporous TiO2 both powder and thin film, with a high capacity to load a large amount of dye. We proved the concept of photodegradation using TiO2 as catalyst. And finally, we show that wine production waste is a possible dye source to DSSCs application.

Einfluss der Führung des Trocknungsprozesses auf den Trocknungsverlauf und die Produkteigenschaften empfindlicher biologischer Güter

Die Konvektionstrocknung ist eine der ältesten Methoden zur Konservierung von Lebensmitteln. Es ist bekannt, dass Agrarprodukte temperaturempfindlich sind. Bei Überhitzung erleiden sie chemische und physikalische Veränderungen, die ihre Qualität vermindern. In der industriellen Praxis wird die Konvektionstrocknung in der Regel auf Grundlage empirisch ermittelter Werte durchgeführt, welche die Produkttemperatur nicht berücksichtigen. Es ist deshalb nicht sichergestellt, ob der Prozess optimal oder auch nur gut betrieben wird. Inhalt dieser Arbeit ist ein Vergleich der klassischen einstufigen Konvektionstrocknung mit einer Prozessführungsstrategie bei der die Produkttemperatur als Regelgröße eingeführt wird. Anhand der Untersuchung des Trocknungsverhaltens von Äpfeln werden die beiden Verfahren analysiert, die erhaltenen Ergebnisse miteinander verglichen und daraus optimierte Trocknungsbedingungen abgeleitet. Die für dieses Projekt entwickelte Prozessanlage erlaubt die simultane Untersuchung sämtlicher wesentlicher Temperaturen, der Gewichtsveränderung und der optischen Qualitätskriterien. Gleichzeitig ist es möglich, entweder die Lufttemperatur oder die Temperatur des Produktes zur regeln, während die jeweils andere Größe als Messwert erfasst wird. Es kann weiterhin zwischen Durch- und Überströmung gewählt werden.

Asociación de los eventos adversos con medicamentos biológicos registrados en el Instituto Nacional de Vigilancia de Medicamentos y Alimentos INVIMA 2014

La función de Farmacovigilancia permite el seguimiento postcomercialización de los medicamentos y productos biológicos ingresados, recibiendo registros de eventos adversos y generando cambios, alertas, señales, que permiten la modificación de la información farmacológica, administración, e incluso la suspensión la comercialización de los medicamentos y productos biológicos autorizados a circulación. A través de este proceso de registro y de estudios clínicos previos a la postcomercialización, se realizan análisis cualitativos y cuantitativos, se generan señales y alertas, así como el perfil de seguridad, herramienta importante en el manejo de cualquier medicamento, para el personal de salud, incluso para el paciente. Las señales se crean de la posible asociación de la reacción adversa con el medicamento, generando cambios en la comercialización y dependen de la calidad en el registro, mejorando la seguridad y calidad de vida de los pacientes. Los productos biológicos, una parte de los medicamentos de reciente introducción y de interés comercial merecen especial atención, dado su potencial y manufactura. En este trabajo se analizó la posible asociación entre las principales reacciones adversas registradas en INVIMA, creando posibles señales en relación con los primeros cinco productos biológicos, y realizando la comparación con los perfiles de seguridad de las principales agencias de referencia internacional. Se encontró similaridad con los perfiles de seguridad de referencia a nivel internacional, y se crearon posibles señales que, aunque no cuentan con causalidad, y se evidencian en su mayoría posibles, sirven de punto de partida de próximas investigaciones.

The thermal stability of yellow fever vaccines

The assessment of yellow fever vaccine thermostability both in lyophilized form and after reconstitution were analyzed. Two commercial yellow fever vaccines were assayed for their thermal stability. Vaccines were exposed to test temperatures in the range of 8 (graus) C to 45 (graus) C. Residual infectivity was measured by a plaque assay using Vero cells. The titre values were used in an accelerated degradation test that follows the Arrhenius equation and the minimum immunizing dose was assumed to be 10 (ao cubo) particles forming unit (pfu)/dose. Some of the most relevant results include that (i) regular culture medium show the same degradation pattern of a reconstituted 17D-204 vaccine; (ii) reconstituted YF-17D-204 showed a predictable half life of more than six days if kept at 0 (graus) C; (iii) there are differences in thermostability between different products that are probably due to both presence of stabilizers in the preparation and the modernization in the vaccine production; (iv) it is important to establish a proper correlation between the mouse infectivity test and the plaque assay since the last appears to be more simple, economical, and practical for small laboratories to assess the potency of the vaccine, and (v) the accelerated degradation test appears to be the best procedure to quantify the thermostability of biological products.
