Post‐trial obligations in the Declaration of Helsinki 2013: classification,reconstruction and interpretation

The general aim of this article is to give a critical interpretation of post‐trial obligations towards individual research participants in the Declaration of Helsinki 2013. Transitioning research participants to the appropriate health care when a research study ends is a global problem. The publication of a new version of the Declaration of Helsinki is a great opportunity to discuss it. In my view, the Declaration of Helsinki 2013 identifies at least two clearly different types of post‐trial obligations, specifically, access to care after research and access to information after research. The agents entitled to receive post‐trial access are the individual participants in research studies. The Declaration identifies the sponsors, researchers and host country governments as the main agents responsible for complying with the post‐trial obligations mentioned above. To justify this interpretation of post‐trial obligations, I first introduce a classification of post‐trial obligations and illustrate its application with examples from post‐trial ethics literature. I then make a brief reconstruction of the formulations of post‐trial obligations of the Declaration of Helsinki from 2000 to 2008 to correlate the changes with some of the most salient ethical arguments. Finally I advance a critical interpretation of the latest formulation of post‐trial obligations. I defend the view that paragraph 34 of ‘Post‐trial provisions’ is an improved formulation by comparison with earlier versions, especially for identifying responsible agents and abandoning ambiguous ‘fair benefit’ language. However, I criticize the disappearance of ‘access to other appropriate care’ present in the Declaration since 2004 and the narrow scope given to obligations of access to information after research.     

Human‐horse sensory engagement through horse archery

The Mongol horse stems from ancient stock, similar to the first horses ridden on the Central Asian grassland steppe. Mongol horses subsequently migrated with their human counterparts throughout Eurasia, as far to the east as Japan. During archery festivals in Japan, horses gallop along a narrow runway within a temple complex in the heavily populated city of Kyoto. In Mongolia, with the recent re‐emergence of the ancient practice, horse and rider still gallop across the expansive grassland steppe. The euphoria one feels in riding fast on horseback with the wind against one's face can be symbolised by the concept of khii mor’ in Mongolia, which is connected with the vitality between human and horse in the practice of horse archery. Through sensory ethnography, in combination with multi‐species ethnography, this article explores embodiment between horse and rider in two quite different socio‐ecological contexts.     

“Making coin” and the networker: Masculine self‐making in the Australian professional managerial class

In this article I unpack the labour of “networking” to understand the changes in sociality and worker identity that have occurred in the Australian professional managerial class workforce under post‐Fordism. Drawing on fieldwork undertaken at the interface of the pubic service and private consultancy firms in Canberra, I break from dominant readings of intimacy in post‐Fordism which preference either a downwards imposition of “ways of being” from capital to worker, or a reactive self‐regulation in line with objective external structures. Networking, I argue, is as much about being recognised as patron as it is about any tangible economic benefits. The intimate relations and self‐fashioning of networking constitute attempts to embody particular classed, sexualised, gendered fantasies of the figure of “the networker” in post‐Fordist Australian business culture. This interpretation does not necessitate overlooking the tangible results of networking, and I discuss too, how masculine fantasy structures the topography of workplaces.     

Histone deacetylases: salesmen and customers in the post‐translational modification market

HDACs (histone deacetylases) are enzymes that remove the acetyl moiety from N‐?‐acetylated lysine residues in histones and non‐histone proteins. In recent years, it has turned out that HDACs themselves are also subject to post‐translational modification. Such structural alterations can determine the stability, localization, activity and protein—protein interactions of HDACs. This subsequently affects the modification of their substrates and the co‐ordination of cellular signalling networks. Intriguingly, physiologically relevant non‐histone proteins are increasingly found to be deacetylated by HDACs, and aberrant deacetylase activity contributes to several severe human diseases. Targeting the catalytic activity of these enzymes and their post‐translational modifications are therefore attractive targets for therapeutical intervention strategies. To achieve this ambitious goal, details on the molecular mechanisms regulating post‐translational modifications of HDACs are required. This review summarizes aspects of the current knowledge on the biological role and enzymology of the phosphorylation, acetylation, ubiquitylation and sumoylation of HDACs.     

The total opportunity for sexual selection and the integration of pre‐ and post‐mating episodes of sexual selection in a complex world

It is well known that sexual selection can target reproductive traits during successive pre‐ and post‐mating episodes of selection. A key focus of recent studies has been to understand and quantify how these episodes of sexual selection interact to determine overall variance in reproductive success. In this article, we review empirical developments in this field but also highlight the considerable variability in patterns of pre‐ and post‐mating sexual selection, attributable to variation in patterns of resource acquisition and allocation, ecological and social factors, genotype‐by‐environment interaction and possible methodological factors that might obscure such patterns. Our aim is to highlight how (co)variances in pre‐ and post‐mating sexually selected traits can be sensitive to changes in a range of ecological and environmental variables. We argue that failure to capture this variation when quantifying the opportunity for sexual selection may lead to erroneous conclusions about the strength, direction or form of sexual selection operating on pre‐ and post‐mating traits. Overall, we advocate for approaches that combine measures of pre‐ and post‐mating selection across contrasting environmental or ecological gradients to better understand the dynamics of sexual selection in polyandrous species. We also discuss some directions for future research in this area.     

Regulation of cytoskeleton‐associated protein activities: Linking cellular signals to plant cytoskeletal function

The plant cytoskeleton undergoes dynamic remodeling in response to diverse developmental and environmental cues. Remodeling of the cytoskeleton coordinates growth in plant cells, including trafficking and exocytosis of membrane and wall components during cell expansion, and regulation of hypocotyl elongation in response to light. Cytoskeletal remodeling also has key functions in disease resistance and abiotic stress responses. Many stimuli result in altered activity of cytoskeleton-associatedproteins,microtubuleassociated proteins(MAPs) and actin-binding proteins(ABPs). MAPs and ABPs are the main players determining the spatiotemporally dynamic nature of the cytoskeleton, functioning in a sensory hub that decodes signals to modulate plant cytoskeletal behavior. Moreover, MAP and ABP activities and levels are precisely regulated during development and environmental responses, but our understanding of this process remains limited. In this review, we summarize the evidence linking multiple signaling pathways, MAP and ABP activities and levels, and cytoskeletal rearrangements in plant cells. We highlight advances in elucidating the multiple mechanisms that regulate MAP and ABP activities and levels, including calcium and calmodulin signaling, ROP GTPase activity, phospholipid signaling, and post-translational modifications.     

The use of post‐translationally modified peptides for detection of biomarkers of immune‐mediated diseases

Biomarkers are decision‐making tools at the basis of clinical diagnostics and essential for guiding therapeutic treatments. In this context, autoimmune diseases represent a class of disorders that need early diagnosis and steady monitoring. These diseases are usually associated with humoral or cell‐mediated immune reactions against one or more of the body's own constituents. Autoantibodies fluctuating in biological fluids can be used as disease biomarkers and they can be, thus, detected by diagnostic immunoassays using native autoantigens. However, it is now accepted that post‐translational modifications may affect the immunogenicity of self‐protein antigens, triggering an autoimmune response and creating neo‐antigens. In this case, post‐translationally modified peptides represent a more valuable tool with respect to isolated or recombinant proteins. In fact, synthetic peptides can be specifically modified to mimic neo‐antigens and to selectively detect autoantibodies as disease biomarkers. A ‘chemical reverse approach’ to select synthetic peptides, bearing specific post‐translational modifications, able to fishing out autoantibodies from patients' biological fluids, can be successfully applied for the development of specific in vitro diagnostic/prognostic assays of autoimmune diseases. Herein, we report the successful application of this approach to the identification of biomarkers in different autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis and multiple sclerosis.

A sensory approach for multispecies anthropology

This special issue suggests that the need to examine the entangled lives of species, selves and other beings through a multisensory perspective is crucial and timely. Developing on a sensory analysis, one that emerges through what Anna Tsing refers to as the ‘arts of noticing’ (2015), this introductory paper explores how both nonhuman and human lives are intertwined, and how their close examination can guide anthropologists in their ability to capture the subtleties of more‐than‐human engagement, connection and relatedness. Through articles within this issue from Australian anthropology and beyond, we ask how becoming‐with more‐than‐humans helps us to construct a post‐humanist analysis in the combination of sensory anthropology and multispecies anthropology. Through a combination of these two fields, the paper suggests, anthropology can take up the opportunity to think about animals as subjects, through our ability to communicate beyond language and to engage in a more meaningful way through interspecies knowledge‐making.     

Post‐fledging survival of Little Owls Athene noctua in relation to nestling food supply

Among the range of determinants of post‐fledging survival in altricial birds, the energy supply to the growing juveniles is likely to play a central role. However, the exact mechanisms shaping post‐fledging survival are poorly understood. Using a food supplementation experiment, we determined the effect of variation in food supply on the survival of juvenile Little Owls Athene noctua from hatching to 2 months post‐fledging. Experimental broods were food‐supplemented for 36 days during the nestling and the early post‐fledging period. The fate of 307 juveniles (95 of them provided with extra food) was determined by nest monitoring and radiotelemetry. In unsupplemented birds, the rates of survival measured at 5‐day intervals were lowest during the nestling stage, remained low during the early post‐fledging stage and steadily increased after about 2 weeks post‐fledging. Food supplementation substantially increased nestling survival, but we detected no direct treatment effect on post‐fledging survival. Instead, we found a strong indirect effect of food supplementation, in that fledglings of good physical condition had markedly higher chances of surviving the post‐fledging period compared with those in poor condition. Experimental food supplementation increased survival over the first 3 months from 45% to 64.6%. This suggests that energy reserves built up during the nestling stage influence post‐fledging survival and ultimately parental reproductive output. The low nestling and post‐fledging survival shows that the early life‐history stages constitute a crucial bottleneck of reproductive ecology in Little Owls. The strong treatment effects on the number of independent offspring indicate that natural variation in food supply is an important determinant of spatio‐temporal patterns in Little Owl demography.     

Sexual coloration and sperm performance in the Australian painted dragon lizard,Ctenophorus pictus

Theory predicts trade‐offs between pre‐ and post‐copulatory sexually selected traits. This relationship may be mediated by the degree to which males are able to monopolize access to females, as this will place an upper limit on the strength of post‐copulatory selection. Furthermore, traits that aid in mate monopolization may be costly to maintain and may limit investment in post‐copulatory traits, such as sperm performance. Australian painted dragons are polymorphic for the presence or absence of a yellow gular patch (‘bibs’), which may aid them to monopolize access to females. Previous work has shown that there are physiological costs of carrying this bib (greater loss of body condition in the wild). Here, we show that male painted dragons use this bright yellow bib as both an inter‐ and intrasexual signal, and we assess whether this signal is traded off against sperm performance within the same individuals. We found no relationship between aspects of bib colour and sperm swimming velocity or percentage of motile sperm and suggest that the bib polymorphism may be maintained by complex interactions between physiological or life‐history traits including other sperm or ejaculate traits and environmental influences.     

Will cognitive enhancement create post‐persons? The use(lessness) of induction in determining the likelihood of moral status enhancement

The prospect of cognitive enhancement well beyond current human capacities raises worries that the fundamental equality in moral status of human beings could be undermined. Cognitive enhancement might create beings with moral status higher than persons. Yet, there is an expressibility problem of spelling out what the higher threshold in cognitive capacity would be like. Nicholas Agar has put forward the bold claim that we can show by means of inductive reasoning that indefinite cognitive enhancement will probably mark a difference in moral status. The hope is that induction can determine the plausibility of post‐personhood existence in the absence of an account of what the higher status would be like. In this article, we argue that Agar's argument fails and, more generally, that inductive reasoning has little bearing on assessing the likelihood of post‐personhood in the absence of an account of higher status. We conclude that induction cannot bypass the expressibility problem about post‐persons.     

Experimental manipulation reveals a trade‐off between weapons and testes

Theory predicts a trade‐off between sexually selected weapons used to secure mates and post‐copulatory traits used to maximize fertilization success. However, individuals that have a greater capacity to acquire resources from the environment may invest more in both pre‐ and post‐copulatory traits, and trade‐offs may not be readily apparent. Here, we manipulate the phenotype of developing individuals to examine allocation trade‐offs between weapons and testes in Mictis profana (Hemiptera: Coreidae), a species where the hind legs are sexually selected weapons used in contests over access to females. We experimentally prevented males from developing weapons by inducing them to autotomize their hind legs before the final moult to adulthood. We compared trait expression in this group to males where autotomy was induced in the mid‐legs, which are presumably not under sexual selection to the same extent. We found males without weapons invested proportionally more in testes mass than those with their mid‐legs removed. Males that developed to adulthood without weapons did not differ from the mid‐leg removal group in other traits potentially under precopulatory sexual selection, other post‐copulatory traits or naturally selected traits. In addition, a sample of adult males from the same population in the wild revealed a positive correlation between investment in testes and weapons. Our study presents a critical contribution to a growing body of literature suggesting the allocation of resources to pre‐ and post‐copulatory sexual traits is influenced by a resource allocation trade‐off and that this trade‐off may only be revealed with experimental manipulation.     

The role of post‐translational modifications in cardiac hypertrophy

Pathological cardiac hypertrophy involves excessive protein synthesis, increased cardiac myocyte size and ultimately the development of heart failure. Thus, pathological cardiac hypertrophy is a major risk factor for many cardiovascular diseases and death in humans. Extensive research in the last decade has revealed that post‐translational modifications (PTMs), including phosphorylation, ubiquitination, SUMOylation, O‐GlcNAcylation, methylation and acetylation, play important roles in pathological cardiac hypertrophy pathways. These PTMs potently mediate myocardial hypertrophy responses via the interaction, stability, degradation, cellular translocation and activation of receptors, adaptors and signal transduction events. These changes occur in response to pathological hypertrophy stimuli. In this review, we summarize the roles of PTMs in regulating the development of pathological cardiac hypertrophy. Furthermore, PTMs are discussed as potential targets for treating or preventing cardiac hypertrophy.     

Alternative Cultural Heterotopia and the Liminoid Body: Beyond Turner at ConFest

This article takes issue with Victor Turner's influential, yet essentialist, category of the limen. While acknowledging Turner's continuing significance in the analysis of public events, I draw upon detailed ethnography of one of Australia's contemporary pilgrimage centres, the alternative lifestyle event ConFest, to reconfigure his project. Although ConFest may prove to be an exemplary field of liminality, as a decidedly contested and sensuous landscape, it demands re‐evaluation of the implicitly consensual and non‐carnal limen. I offer the concepts of alternative cultural heterotopia and liminoid embodiment, with the purpose of fashioning new directions in the study of alternative lifestyle, and other public events. Attending to contemporary pilgrimage research, spatial analysis and applying the ideas of Michel Maffesoli and Hakim Bey, this is a post‐structuralist contribution to the anthropology of public events.     

Female wolf spiders exert cryptic control drastically reducing ejaculate size

Sexes' roles in post‐copulatory processes have important effects on individual fitness and are promising to study in species showing complex mating behaviours. In the spider Schizocosa malitiosa, males perform two different copulatory patterns, pattern 1 includes 80% of total pedipalp insertions and pattern 2 includes 20%. Both patterns produce similar number of offspring, but pattern 1 induces higher female reluctance to remating than pattern 2. We hypothesised that the complex copulatory patterns are linked to post‐copulatory sexual selection, affecting males' sperm transfer and the resulting sperm storage by females. First, we examined amounts of sperm in males and live females from uninterrupted (pattern 1 + 2) and interrupted matings (pattern 1, pattern 2). Second, in order to disentangle male and female actions, we induced males to mate with dead females and examined amounts of sperm. Males transfer in total 71% of the sperm available in their pedipalps, being higher but not significant in pattern 1 than in pattern 2. Females drastically reduced the amount of sperm stored in their spermathecae and such control is stronger in pattern 1 compared to pattern 2 matings. We propose that cryptic female control is a main factor driving males to strengthen sperm transfer. Active female reduction in ejaculate most probably diminished her reluctance to remate.     

Correlation of serum oestrogen with salivary calcium in post-menopausal women with and without oral dryness feeling

doi: 10.1111/j.1741‐2358.2011.00580.x
Correlation of serum oestrogen with salivary calcium in post‐menopausal women with and without oral dryness feeling Objective: The aim of this study was to verify the association between salivary calcium and serum oestrogen levels with oral dryness in post‐menopausal women. Also, the correlation between these variables was evaluated. Methods: A case‐control study was carried out on 60 selected menopausal women with and without oral dryness feeling (30 as case and 30 as control) conducted in the Department of Oral Medicine and Radiology, Maharishi Markandeshar University, Mullana, India. Paraffin‐stimulated saliva samples were obtained by expectoration. Salivary calcium concentrations were assessed colorimetrically using Arsenazo III reaction. The serum oestrogen concentration was measured using ELISA. Statistical analysis of Student’s t‐test and Pearson correlation was used. Results: There was significant difference in mean values of both salivary calcium concentration and serum oestrogen between case and control groups. The result obtained also showed that an inverse correlation was found between salivary calcium concentration and serum oestrogen levels in both the groups and in total sample size. Conclusion: Oral dryness in post‐menopausal women is associated with high levels of salivary calcium and low levels of serum oestrogen. The concentrations of salivary calcium and serum oestrogen are inversely correlated in post‐menopausal women, regardless of the presence or absence of oral dryness.     

Tunnel Vision: Part One – Resisting post‐colonialism in Australian anthropology

This essay is based on my conviction that Australian ethnography's narrow purview and anthropology's theoretical limitations need exploring and explaining. While internationally the discipline developed new sites, new theoretical fields and new political ideas in the post‐colonial era from around 1970, classicism continued to dominate research in Australia. New forms of Aboriginal social life and politics created by changing ‘post‐colonial’ conditions largely escaped ethnographic attention, but anthropology was rescued from irrelevance with the emergence of opportunities to assist the courts and Aborigines with land retrievals. By examining selected ethnographies and exceptions to the discipline's main trajectory, I hope to encourage reflection and expansion so that the discipline might realise its potential as the most radical and critical of the social sciences.     

Post‐fledging survival of altricial birds: ecological determinants and adaptation

For altricial young, fledging is an abrupt step into an unknown environment. Despite increasing numbers of studies addressing the post‐fledging period, our current knowledge of the causes and consequences of post‐fledging survival remains fragmentary. Here, we review the literature on post‐fledging survival of juvenile altricial birds, addressing the following main questions: Is low post‐fledging survival a bottleneck in the altricial reproductive cycle? What is known of proximate and ultimate causal factors such as trophic relations (food and predation), habitat conditions, or abiotic factors acting in the post‐fledging period? We analyzed weekly survival estimates from 123 data series based on studies of 65 species, covering weeks 1–13 post‐fledging. As a general pattern, survival of fledglings was low during the first week post‐fledging (median rate = 0.83), and improved rapidly with time post‐fledging (week 4 median rate = 0.96). For ground‐nesting species, survival immediately after leaving nests was similar to egg‐to‐fledging survival. For species breeding above‐ground, survival during the first week post‐fledging was substantially lower than during both the nestling period and later post‐fledging stages. Thus, the early post‐fledging period is a bottleneck of markedly elevated mortality for most altricial species. Predation was the main proximate cause of mortality. Various factors such as habitat, annual and seasonal variation in the environment, and the physical condition of fledglings have been found to affect post‐fledging survival. Individual survival depended strongly on physical traits such as mass and wing length, which likely influence the ability of fledglings to escape predation. Trophic relationships at various levels are the main ultimate driver of adaptation of traits relevant to survival during the pre‐ and post‐fledging periods. Spatiotemporal dynamics of food resources determine the physical development of juveniles and, in turn, their performance after fledging. However, predators can cause quick and efficient selection for fledgling traits and adult breeding decisions. Parental strategies related to clutch size and timing of breeding, and the age and developmental stage at which young fledge have substantial effects on post‐fledging survival. The intensity and duration of post‐fledging parental investment also influences fledgling survival. Post‐fledging mortality is therefore not a random and inevitable loss. Traits and strategies related to fledging and the post‐fledging stage create large fitness differentials and, therefore, are integral, yet poorly understood, parts of the altricial reproductive strategy.     

The German debate on male circumcision and Habermas’ model of post‐secularity

This paper considers Habermas’ model of a post‐secular political order in the light of the debate on male circumcision that arose in Germany after a court ruled that male circumcision was an unjustifiable act of bodily harm. Central to this model is the idea that religious reasons can only become effective in central legal institutions when they are translated into secular reasons. My paper demonstrates that there are two distinguishable readings of this proviso. On the one hand, there is a broad reading according to which it is only necessary to reach a conclusion that is in line with the democratic principle stating that all citizens can be regarded as co‐legislators even if non‐generalizable value orientations might then shape the interpretation of fundamental rights (in the case of circumcision, the right to bodily integrity). On the other hand, a truly secular (narrow) reading would avoid the inclusion of non‐generalizable value orientations. The debate on circumcision demonstrates that these two interpretations lead to different and conflicting modes of justification. The broad reading allows for a justification of male circumcision, whereas the narrow reading makes such a justification unlikely. In addition, the filtering function of the proviso is weakened in a broad reading.
