  • Precaution and Ethics: Handling risks, uncertainties and knowledge gaps in the regulation of new biotechnologies
  • 2017
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • This volume outlines and analyses ethical issues actualized by applying a precautionary approach to the regulation of new biotechnologies. It presents a novel way of categorizing and comparing biotechnologies from a precautionary standpoint. Based on this, it addresses underlying philosophical problems regarding the ethical assessment of decision-making under uncertainty and ignorance, and discusses how risks and possible benefits of such technologies should be balanced from an ethical standpoint. It argues on conceptual and ethical grounds for a technology neutral regulation as well as for a regulation that not only checks new technologies but also requires old, inferior ones to be phased out. It demonstrates how difficult ethical issues regarding the extent and ambition of precautionary policies need to be handled by such a regulation, and presents an overarching framework for doing so.

  • Optimizing yeast as a host for recombinant protein production
  • 2011
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • Having access to suitably stable, functional recombinant protein samples underpins diverse academic and industrial research efforts to understand the workings of the cell in health and disease. Synthesizing a protein in recombinant host cells typically allows the isolation of the pure protein in quantities much higher than those found in the protein's native source. Yeast is a popular host as it is a eukaryote with similar synthetic machinery to the native human source cells of many proteins of interest, whilst also being quick, easy and cheap to grow and process. Even in these cells the production of some proteins can be plagued by low functional yields. We have identified molecular mechanisms and culture parameters underpinning high yields and have consolidated our findings to engineer improved yeast cell factories. In this chapter we provide an overview of the opportunities available to improve yeast as a host system for recombinant protein production.

  • Nitrogen and redox metabolism in Saccharomyces cerevisiae - Impact on cellular activity and ethanol production.
  • 2010
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • Ethanol production by yeast fermentation has been in focus of mankind for millennia, initially, as consumable products like wine and beer, and recently as an environmental-friendly fuel. To obtain an efficient industrial production further knowledge of yeast metabolism is needed to increase the product purity. In this work, the nitrogen and redox metabolism in yeast and its implications on by-product formation and yeast physiology have been studied. In this respect, amino acid biosynthesis plays a substantial role and the central amino acid, glutamate, where used as the sole source of nitrogen. Such cultures were studied in depth by characterizing extra- and intracellular metabolite formation, carbon flows, protein expression and enzyme activities. Glycerol is formed as the main by-product during anaerobic conditions to balance redox equivalents formed during biosynthesis of mainly amino acids. Thus, using amino acids as nitrogen source it was found that glycerol formation was reduced as predicted by theoretical calculations. The results presented in this work have implications for both basic yeast research as well as development of yeast bioprocesses.

  • Bioterrorism och media
  • 2004
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • Attacker med biologiska och kemiska preparat är ett nytt hot mot institutioner i världen bl.a massmedia. I USA har ett antal medieföretag attackerats med brev som visat sig innehålla mjältbrand. I Sverige utsätts medier för hot och risker med jämna mellanrum. Denna guide om säkerhet och beredskap ger ny kunskap om vad bioterrorism innebär och vilka hotbilder som finns mot medieföretag i Sverige. Den vänder sig också till informationsstrateger vid myndigheter och företag liksom till hälso- och sjukvårdspersonal med intresse för epidemiologiska frågor. Guiden inleds med företal av Gorm Albrechtsen, f.d. chefredaktör vid Herning Folkeblad i Danmark som utsatts för misstänkta pulverbrev samt av Åke Sellström, avdelningschef vid Totalförsvarets forskningsinstitut (FOI) och expert på biologiska och kemiska vapen.

  • Pure Selection. The Ethics of Preimplantation Genetic Diagnosis and Choosing Children without Abortion
  • 1999
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • Preimplantation ge¬netic diagnosis (PGD) is taken to mark the starting-point of a new phase in human reproduction, where the possibility of choosing children on genetic grounds without having to resort to ethi¬cally controversial procedures (such as abortion) will grad¬ually increase. Ethical and political issues actu¬alised by this develop¬ment are addressed. The discussion touches upon issues regarding the moral status of em¬bryos and gametes, the moral import of respecting individual auton¬omy and its implications for the requirement of informed consent in health-care, the connec¬tion between sickness, dis¬ability and the value of life, the moral status of possible future people, and the connection between choosing children and eugenic policies of the past. Practical policy issues are adressed on the basis of this, as well as an empirical case-study of the intro¬duction of PGD in Sweden. The book ends up in a set of recommendations regarding the management of re¬search on, introduction and routine use of procedures for pure se¬lection, both within health care and from the point of view of society as a whole. It is argued that research on such procedures should be allowed and supported by society. However, tight restrictions regarding the clinical introduction of new procedures in this area is highly desirable. A rough model for implementing such re¬strictions is also pre¬sented. It is further asserted that, although reasons of economy and safety should limit the access to pure se¬lection, society should not apply any explicit restrictions based on ideasregarding how different traits affect a person’s quality of life. It is stressed that, in order to to avoid a re¬sur¬rection of eugenic policies of the past, the development in this field un¬der¬lines the need for continued and strengthen public support to the sick, dis¬abled and mentally retarded.

  • The Price of Precaution and the Ethics of Risk
  • 2011
  • Bok (övrigt vetenskapligt/konstnärligt)abstract
    • Since a couple of decades, the notion of a precautionary principle plays a central and increasingly influential role in international as well as national policy and regulation regarding the environment and the use of technology. Urging society to take action in the face of potential risks of human activities in these areas, the recent focus on climate change has further sharpened the importance of this idea. However, the idea of a precautionary principle has also been problematised and criticised by scientists, scholars and policy activists, and been accused of almost every intellectual sin imaginable: unclarity, impracticality, arbitrariness and moral as well as political unsoundness. In that light, the very idea of precaution as an ideal for policy making rather comes out as a dead end. On the basis of these contrasting starting points, Christian Munthe undertakes an innovative, in-depth philosophical analysis of what the idea of a precautionary principle is and should be about. A novel theory of the ethics of imposing risks is developed and used as a foundation for defending the idea of precaution in environmental and technological policy making against its critics, while at the same time avoiding a number of identified flaws. The theory is shown to have far-reaching consequences for areas such as bio-, information- and nuclear technology, and global environmental policy in areas such as climate change. The author argues that, while the price we pay for precaution must not be too high, we have to be prepared to pay it in order to act ethically defensible. A number of practical suggestions for precautionary regulation and policy making are made on the basis of this, and some challenges to basic ethical theory as well as consumerist societies, the global political order and liberal democracy are identified
