Beneath the rhetoric: the role of rights in the practice of non-anonymous gamete donation

The use of rights based arguments to justify claims that donor offspring should have access to information identifying their gamete donor has become increasingly widespread. In this paper, I do not intend to revisit the debate about the validity of such rights. Rather, the purpose is to examine the way that such alleged rights have been implemented by those legislatures that have allowed access to identifying information. I will argue that serious inconsistencies exist between the claim that donor offspring have a right to know the identity of their gamete donor and the way such a right is currently met in practice. I hope to show that in systems where non-anonymous donation is practised, an understanding of the proclaimed right of donor offspring to know their genetic identity is one composed of two different rights – the right to know the circumstances of their conception and the right to information identifying the gamete donor – can provide important insights into this important area of public policy.

Managing ethical challenges around misattributed parentage within the clinical context: Insights from an African moral theory

This study argues the thesis that a set of guidelines ‐ firmly rooted in a particular interpretation of African moral theory, specifically, Ubuntu – will do a better job than current medical ethics frameworks, in addressing ethical challenges around misattributed parentage within the clinical context. Incidental information such as information with significant personal/health implications raises unique challenges for medical professionals. For example, withholding information of misattributed paternity accidentally discovered in clinical interactions may be seen by a patient as a violation of his/her right‐to‐know. Contrarily, disclosure where a patient has not requested information – or where establishing paternity is not the purpose of clinical visit/interaction – may be taken by the patient as a violation of his/her right ‘not‐to‐know’. Resolving these challenges remain a herculean task. African moral theory contains an under‐emphasized value for addressing such ethical challenges around misattributed parentage in the field of transplant. I seek to contribute this knowledge; and enhance clinician‐patient relationship. This study builds off three completed systematic reviews, which aimed to answer the following questions: “what are the ethical challenges regarding information health professionals face within the clinical contest?” and “what core aspects (or common themes) of Ubuntu can be identified in existing literature describing the same?” In this present study, I applied the definition of Ubuntu which captures the core aspects of the theory in ethical literature on the same, to address ethical issues around unsought information of misattributed parentage in the field of transplant.     

An enzyme family reunion — similarities,differences and eccentricities in actions on <Emphasis Type="Italic">α</Emphasis>-glucans

α-Glucans in general, including starch, glycogen and their derived oligosaccharides are processed by a host of more or less closely related enzymes that represent wide diversity in structure, mechanism, specificity and biological role. Sophisticated three-dimensional structures continue to emerge hand-in-hand with the gaining of novel insight in modes of action. We are witnessing the “test of time” blending with remaining questions and new relationships for these enzymes. Information from both within and outside of ALAMY_3 Symposium will provide examples on what the family contains and outline some future directions. In 2007 a quantum leap crowned the structural biology by the glucansucrase crystal structure. This initiates the disclosure of the mystery on the organisation of the multidomain structure and the “robotics mechanism” of this group of enzymes. The central issue on architecture and domain interplay in multidomain enzymes is also relevant in connection with the recent focus on carbohydrate-binding domains as well as on surface binding sites and their long underrated potential. Other questions include, how different or similar are glycoside hydrolase families 13 and 31 and is the lid finally lifted off the disguise of the starch lyase, also belonging to family 31? Is family 57 holding back secret specificities? Will the different families be sporting new “eccentric” functions, are there new families out there, and why are crystal structures of “simple” enzymes still missing? Indeed new understanding and discovery of biological roles continuously emphasize value of the collections of enzyme models, sequences, and evolutionary trees which will also be enabling advancement in design for useful and novel applications.     

What can we Learn from Patients’ Ethical Thinking about the right ‘not to know’ in Genomics? Lessons from Cancer Genetic Testing for Genetic Counselling

This article is based on a qualitative empirical project about a distinct kinship group who were among the first identified internationally as having a genetic susceptibility to cancer (Lynch Syndrome). 50 were invited to participate (42 were tested; eight declined genetic testing). 15, who had all accepted testing, were interviewed. They form a unique case study. This study aimed to explore interviewees’ experiences of genetic testing and how these influenced their family relationships. A key finding was that participants framed the decision to be tested as ‘common sense’; the idea of choice around the decision was negated and replaced by a moral imperative to be tested. Those who did not follow ‘common sense’ were judged to be imprudent. Family members who declined testing were discussed negatively by participants. The article addresses what is ethically problematic about how test decliners were discussed and whether these ethical concerns extend to others who are offered genetic testing. Discussions showed that genetic testing was viewed as both an autonomous choice and a responsibility. Yet the apparent conflict between the right to autonomy and the moral imperative of responsibility allowed participants to defend test decliners’ decisions by expressing a preference for or defending choice over responsibility. The ‘right not to know’ seemed an important moral construct to help ethically manage unpopular decisions made by close family who declined testing. In light of this research, the erosion of the ‘right not to know’ in the genomic age could have subtle yet profound consequences for family relationships.     

The Tipping of the Big Stone—And Life itself. Obesity,Moral Work and Responsive Selves Over Time

Why is “everything I know is the right thing to do a million miles removed from what I do in reality?” This question posed by Rita, my main interlocutor and friend in a fieldwork that started in 2001–2003 and was taken up again in 2014–2015, opens up an exploration of moral work and moral selves in the context of the obesity epidemic and weight loss processes. I address these questions through the notion of “moral laboratories” taking up Mattingly’s argument that moral cultivation over time cannot be disconnected from a notion of self. Mattingly has consistently argued for a biographical and narrative self, which is processual and created in community. Along these lines, and by recourse to the German philosopher Bernhard Waldenfels’ phenomenology, I will propose the notion of a responsive self. The responsive self highlights the eventness of ongoing experimentation against the odds and captures equally pathic and agentive dimensions of a self that both persists and is transformed over time.     

When is a parasite species a species?

Regrettably, 140 years after the publication of Darwin's Origin of Species, we face the grotesque situation that we still do not know what is a species whose origin Darwin wanted to explain. A generally applicable species definition is not available. Is there a basic unit of biodiversity above the level of individuals? Do we try to define something that does not exist in reality? The strong potential for the evolution of genetic variability in parasites together with the importance of species diagnosis for applied fields of parasite research make biodiversity research a key role in parasitology. Frequent occurrence of sympatric speciation, clonal reproduction, selfing, sib mating or parthenogenesis imply exceptional conditions for the evolution of gene pool diversities in parasites.     

Evolutionary genetics and ecology of sperm-dependent parthenogenesis

Sperm-dependent (or pseudogamous) forms of parthenogenetic reproduction occur in a wide variety of animals. Inheritance is typically clonal and matroclinous (of female descent), but sperm are needed to initiate normal development. As opposed to true parthenogenesis (i.e., sperm-independent reproduction), pseudogamous parthenogenetic lineages must coexist with a ‘sperm donor’— e.g., males from a conspecific sexual lineage, conspecific hermaphrodites, or males from a closely related sexual species. Such sperm donors do not contribute genetically to the next generation. The parasitic nature of sperm-dependent parthenogenesis raises numerous ecological and evolutionary questions. How do they arise? What factors help stabilize coexistence between the pseudogamous parthenogens and their sperm donors (i.e., ‘sexual hosts’)? Why do males waste sperm on the asexual females? Why does true parthenogenesis not evolve in pseudogamous lineages and free them from their dependency on sperm donors? Does pseudogamous parthenogenesis provide compensatory benefits that outweigh the constraints of sperm-dependence? Herein, we consider some genetic, ecological, and geographical consequences of sperm-dependent parthenogenesis in animals.     

Ontogenetic phenotypic plasticity during the reproductive phase in Arabidopsis thaliana (Brassicaceae)

While phenotypic plasticity has been the focus of much research and debate in the recent ecological and evolutionary literature, the developmental nature of the phenomenon has been mostly overlooked. A developmental perspective must ultimately be an integral part of our understanding of how organisms cope with heterogeneous environments. In this paper I use the rapid cycling Arabidopsis thaliana to address the following questions concerning developmental plasticity. (1) Are there genetic and/or environmental differences in parameters describing ontogenetic trajectories? (2) Is ontogenetic variation produced by differences in genotypes and/or environments for two crucial traits of the reproductive phase of the life cycle, stem elongation and flower production? (3) Is there ontogenetic variability for the correlation between the two characters? I found genetic variation, plasticity, and variation for plasticity affecting at least some of the growth parameters, indicating potential for evolution via heterochronic shifts in ontogenetic trajectories. Within-population differences among families are determined before the onset of the reproductive phase, while among-population variation is the result of divergence during the reproductive phase of the ontogeny. Finally, the ontogenetic profiles of character correlations are very distinct between the ecologically meaningful categories of early- and late-flowering “ecotypes” in this species, and show susceptibility to environmental change.     

Species richness of sawfly–host plant associations at higher taxonomic levels

Insect–plant interactions are important to understanding the evolutionary mechanisms responsible for most of the diverse plant‐feeding insects. We aggregated data on sawfly–host plant associations and other resource associations from existing sources to address the following questions: (i) Is there a general correlation between host diversity and sawfly species richness? (ii) Is the pattern of host plant use consistent across sawfly lineages? and (iii) Is there a phylogenetically significant shift in species richness among sawflies? Our analysis comprised 8567 sawfly species, including 2087 species with host plant and other records. In total, there were 2126 records of host usage for sawflies, the overwhelming majority of which were sawflies using angiosperms as resources. Rosales are used by most of the species in sawfly families or subfamilies. We found that there was a strong correlation between the number of host plant orders and the species richness of sawfly families and subfamilies. To examine the points at which sawflies have experienced significant shifts in species richness, we compared sister taxon species richness. Several positive and negative shifts in species richness among sawflies were related to their range of host plant usage and specialized niche, respectively. In general, we found that most of the sawfly families and subfamilies used several orders as host plants, but mainly core eudicots, although some families or subfamilies were specialized on pteridophytes or gymnosperms.     

Fifteen compelling open questions in plant cell biology

As scientists, we are at least as excited about the open questions—the things we do not know—as the discoveries. Here, we asked 15 experts to describe the most compelling open questions in plant cell biology. These are their questions: How are organelle identity, domains, and boundaries maintained under the continuous flux of vesicle trafficking and membrane remodeling? Is the plant cortical microtubule cytoskeleton a mechanosensory apparatus? How are the cellular pathways of cell wall synthesis, assembly, modification, and integrity sensing linked in plants? Why do plasmodesmata open and close? Is there retrograde signaling from vacuoles to the nucleus? How do root cells accommodate fungal endosymbionts? What is the role of cell edges in plant morphogenesis? How is the cell division site determined? What are the emergent effects of polyploidy on the biology of the cell, and how are any such “rules” conditioned by cell type? Can mechanical forces trigger new cell fates in plants? How does a single differentiated somatic cell reprogram and gain pluripotency? How does polarity develop de-novo in isolated plant cells? What is the spectrum of cellular functions for membraneless organelles and intrinsically disordered proteins? How do plants deal with internal noise? How does order emerge in cells and propagate to organs and organisms from complex dynamical processes? We hope you find the discussions of these questions thought provoking and inspiring.

We asked 15 experts to address what they consider to be the most compelling open questions in plant cell biology and these are their questions.     

Naturally occurring genetic variation in the age-specific immune response of Drosophila melanogaster

Immunosenescence, the age‐related decline in immune response, is a well‐known consequence of aging. To date, most studies of age‐related changes in immune response focused on the cellular and physiological bases of this decline; we have virtually no understanding of the genetic basis of age‐related changes in the immune system or if indeed such control exists. We used 25 chromosome substitution lines of Drosophila melanogaster derived from a natural population to address three questions: (i) How is the function of the innate immune system influenced by age? (ii) Is there a genetic basis for phenotypic variation in immune response at different ages? (iii) Is there a genetic basis for differences in the way that age influences the immune function? Virgin females from each line were assayed for immune response using clearance of infection with Escherichia coli at 1 and 4 weeks of age. We found significant genetic variation among lines in immune response at each age. Unexpectedly, when averaged across all lines, the immune response actually improved with age. However, there was significant variation in the effect of age on immune response with 11 lines showing improvement, nine lines showing no change and five exhibiting a decline with age. There was no genetic correlation of immune response across ages suggesting that different loci contribute to variation in immune response at each age. The genetic component of the variation in immune response increased with age, a pattern predicted by the mutation accumulation model of senescence. However, this increase in variation resulted in part from the improvement of the immune response in some lines with age. Thus the observed changes in genetic variation in immune function with age are not entirely explained by the mutation accumulation model.     

Freedom and a right (not) to know

The article discusses the relationship between the notion of a moral right to personal self-determination, the notion of a moral right to know and the notion of a moral right not to know. In particular, the author asks under what conditions, if any, the right to self-determination implies a right to have information or a right not to have information. The conclusions he defends are theoretical in character rather than concrete norms and directions, and they are intended to be relevant in many contexts, not only in the context of information concerning, say, medical decisions. Yet the author restates the question concerning the right to have and especially the right not to have genetic knowledge about one's own genes on the basis of a right to self-determination. He argues that a right (not) to have genetic information can be defended on the ground of a right to self-determination, but that this kind of defense presupposes several normative, and controversial, arguments.     

Frozen embryos, genetic information and reproductive rights

Recent ethical and legal challenges have arisen concerning the rights of individuals over their IVF embryos, leading to questions about how, when the wishes of parents regarding their embryos conflict, such situations ought to be resolved. A notion commonly invoked in relation to frozen embryo disputes is that of reproductive rights: a right to have (or not to have) children. This has sometimes been interpreted to mean a right to have, or not to have, one's own genetic children. But can such rights legitimately be asserted to give rise to claims over embryos? We examine the question of property in genetic material as applied to gametes and embryos, and whether rights over genetic information extend to grant control over IVF embryos. In particular we consider the purported right not to have one's own genetically related children from a property‐based perspective. We argue that even if we concede that such (property) rights do exist, those rights become limited in scope and application upon engaging in reproduction. We want to show that once an IVF embryo is created for the purpose of reproduction, any right not to have genetically‐related children that may be based in property rights over genetic information is ceded. There is thus no right to prevent one's IVF embryos from being brought to birth on the basis of a right to avoid having one's own genetic children. Although there may be reproductive rights over gametes and embryos, these are not grounded in genetic information.     

The racialised and classed constitution of English village life

This article explores ethnographically the ‘village’ as a stage for the enactment and reproduction of a racialised set of white middle-class social and moral values. To do this I draw upon interview material with middle-class whites who live in a suburban ‘village’ on the border of rural Leicestershire and urban Leicester in England. I explore the way in which my co-conversationalists reflexively and imaginatively defend their area's ‘village’ identity through a discourse that ‘others’ its wealthy Asian residents. Although these raced others have achieved economic parity with the more affluent wealthy white middle-class residents, they are imagined to lack the ‘proper’ middle-class values of respectability and decorum, which are associated with the traditional white rhythms of English village life.     

Sex-specific pattern of spatial genetic structure in dioecious and clonal tree species, <Emphasis Type="Italic">Populus alba</Emphasis> L.

Fine-scale spatial genetic structure (SGS) has profound ecological and genetic consequences for plant populations, and some studies indicate that clonal reproduction may significantly enhance SGS. Clonality is widespread among dioecious species, but little is known about the relationship between clonal reproduction and SGS in the frame of sexual dimorphism. We asked the following questions: (1) Is there a sexually dependent pattern of SGS in white poplar population? (2) What is the relationship between clonal reproduction and SGS? and (3) Does this relationship have a sex-specific component? Using 16 microsatellite markers, genetic structure including fine-scale SGS and clonality of females and males of white poplar were investigated. Significant SGS was noted for both sexes at the ramet and genet levels. At the genet level, males had 2.7-fold higher SGS than that of females. Clonality significantly contributed to SGS only in females. A sibship structure revealed with pedigree analysis and clustering-based methods among males was likely the major factor of the observed SGS. The sexes differed in their clonal growth strategies. Spatial positioning of ramets in female clones suggested foraging behavior and/or avoidance of competition, while for male clones it indicated more expansion and space colonization. The obtained results led us to conclude that sexual dimorphism in life history traits may affect the course and rate of demo-genetic processes acting in natural populations of dioecious species. To our knowledge, this is the first study demonstrating a sex-specific pattern of SGS in natural populations of dioecious species.     

L’entretien psychologique systématique pour les couples optant pour l’IAD: huit ans d’expérience clinique dans une législation prévoyant la levée de l’anonymat du donneur

A law on medically assisted procreation was implemented in Switzerland in 2001. This law is subordinate to the well-being of the child and stipulates that only married couples can benefit from donor insemination (DI). Furthermore, a child who was conceived with donor sperm may obtain access to information including the identity of the donor on reaching adulthood, at age 18. The law also specifies that psychological assistance must be offered before, during, and after treatment. For the past 12 years, the Unit of Reproductive Medicine and the Center of Medically Assisted Procreation in Lausanne employ a concept of psychological assistance adjusted to each couple’s needs, called “ressource counselling”. In preparation for DI, specific questions are examined, such as “Should the child be informed about the donor insemination, should others be informed, if so, how and when?” These questions may also be discussed in a group setting specific for couples concerned with DI. Our experience shows that systematic counselling helps couples in finding their own path through the delicate subjects of secrecy, attachment, and the rights of a child to be informed of his/her genetic links.     

Experiences of Genetic Risk: Disclosure and the Gendering of Responsibility

The question of ‘who owns genetic information‘ is increasingly a focus of ethical inquiry. Applied to predictive testing, several recent critiques suggest that persons with a genetic disorder have a moral duty to disclose that information to other family members. The justification for this obligation is that genetic information belongs to and may benefit not only a single individual, but also members of a biological kinship. This paper considers this issue from a different vantage point: How does gender intersect with the moral duty to disclose genetic information? Scholars have argued that gender is partly comprised of distinct assignments and assumptions of responsibility. Thus, there is a danger that gendered patterns of socialization will make women feel that they should take primary responsibility for disclosing genetic information to others. This article explores issues of responsibility and disclosure of risk information by drawing on an empirical study of women and men who have undergone genetic testing for hereditary breast/ovarian cancer. The research study suggests that disclosure of genetic information is a gendered activity, with both the benefits and burdens of this task falling primarily on women. It also illustrates that when disclosure is understood contextually, it is a far more complicated matter than when viewed through a theoretical lens. The article considers the relevance of these findings on ethical debate and genetic counselling practices.     

Low Levels of Empathic Concern Predict Utilitarian Moral Judgment

Is it permissible to harm one to save many? Classic moral dilemmas are often defined by the conflict between a putatively rational response to maximize aggregate welfare (i.e., the utilitarian judgment) and an emotional aversion to harm (i.e., the non-utilitarian judgment). Here, we address two questions. First, what specific aspect of emotional responding is relevant for these judgments? Second, is this aspect of emotional responding selectively reduced in utilitarians or enhanced in non-utilitarians? The results reveal a key relationship between moral judgment and empathic concern in particular (i.e., feelings of warmth and compassion in response to someone in distress). Utilitarian participants showed significantly reduced empathic concern on an independent empathy measure. These findings therefore reveal diminished empathic concern in utilitarian moral judges.     

Is an account of identity necessary for bioethics? What post-genomic biomedicine can teach us

Is a theory of identity necessary for bioethics? In this paper I investigate that question starting from an empirical explication of identity based on post-genomics, in particular on epigenetics. After analysing whether the classic problems a theory of identity has to cope with (fictional transplants; conjoined twins; and definition of death) also affect the proposed epigenetic account of identity, I deal with three topics (the assumption of moral responsibility; decision maintenance in the case of advance directives; and the attribution of value to human beings at given developmental stages) to offer an insight on the relationship between that account and bioethics.
