Background: Recent analyses have shown that in health services research in Germany, healthcare organisations are often considered primarily as a study setting, without fully taking their complex organisational nature into account, neither theoretically nor methodologically. Therefore, an initiative was launched to analyse the state of Organisational Health Services Research (OHSR) in Germany and to develop a strategic framework and road map to guide future efforts in the field. This paper summarizes positions that have been jointly developed by consulting experts from the interdisciplinary and international scientific community., Methods: In July 2023, a scoping workshop over the course of three days was held with 32 (inter)national experts from different research fields centred around OHSR topics using interactive workshop methods. Participants discussed their perspectives on OHSR, analysed current challenges in OHSR in Germany and developed key positions for the field's development., Results: The seven agreed-upon key positions addressed conceptual and strategic aspects. There was consensus that the field required the development of a research agenda that can guide future efforts. On a conceptual level, the need to address challenges in terms of interdisciplinarity, terminology, organisation(s) as research subjects, international comparative research and utilisation of organisational theory was recognized. On a strategic level, requirements with regard to teaching, promotion of interdisciplinary and international collaboration, suitable funding opportunities and participatory research were identified., Conclusions: This position paper seeks to serve as a framework to support further development of OHSR in Germany and as a guide for researchers and funding organisations on how to move OHSR forward. Some of the challenges discussed for German OHSR are equally present in other countries. Thus, this position paper can be used to initiate fruitful discussions in other countries., Competing Interests: LA ist Vorstandsmitglied der DGMS und des DNVF.

AI technologies are drawing increasing attention among international relations (IR) scholars. Ingvild Bode reviews this literature through considering, in particular, the extent to which such studies continue to use or expand on well-traded analytical frameworks. She finds that scholarship on AI in IR can look back at a longer-than-expected trajectory and centres on four key themes: the balance of power; disinformation; governance; and ethics. Much of this literature works with well-established IR conceptualisations, while studies across three emerging themes - (re)conceptualising technology, beyond the AI arms race, and unpacking relevant actors - push and expand established disciplinary frameworks. ◼., (© 2024 The Author(s).

Thyroid cancer diagnosis primarily relies on imaging techniques and cytological analyses. In cases where the diagnosis is uncertain, the quantification of molecular markers has been incorporated after cytological examination. This approach helps physicians to make surgical decisions, estimate cancer aggressiveness, and monitor the response to treatments. Despite the availability of commercial molecular tests, their widespread use has been hindered in our experience due to cost constraints and variability between them. Thus, numerous groups are currently evaluating new molecular markers that ultimately will lead to improved diagnostic certainty, as well as better classification of prognosis and recurrence. In this review, we start reviewing the current preoperative testing methodologies, followed by a comprehensive review of emerging molecular markers. We focus on micro RNAs, long non-coding RNAs, and mitochondrial (mt) signatures, including mtDNA genes and circulating cell-free mtDNA. We envision that a robust set of molecular markers will complement the national and international clinical guides for proper assessment of the disease.

This essay examines how artificial intelligence (AI) technologies may shape international norms. Following a brief discussion of the ways in which AI technologies pose new governance questions, we reflect on the extent to which norm research in the discipline of International Relations (IR) is equipped to understand how AI technologies shape normative substance. Norm research has typically focused on the impact and failure of norms, offering increasingly diversified models of norm contestation, for instance. But present research has two shortcomings: a near-exclusive focus on modes and contexts of norm emergence and constitution that happen in the public space; and a focus on the workings of a pre-set normativity (ideas of oughtness and justice) that stands in an unclear relationship with normality (ideas of the standard, the average) emerging from practices. Responding to this, we put forward a research programme on AI and practical normativity/normality based on two pillars: first, we argue that operational practices of designing and using AI technologies typically performed outside of the public eye make norms; and second, we emphasise the interplay of normality and normativity as analytically influential in this process. With this, we also reflect on how increasingly relying on AI technologies across diverse policy domains has an under-examined effect on the exercise of human agency. This is important because the normality shaped by AI technologies can lead to forms of non-human generated normativity that risks replacing conventional models about how norms matter in AI-affected policy domains. We close with sketching three future research streams. We conclude that AI technologies are a major, yet still under-researched, challenge for understanding and studying norms. We should therefore reflect on new theoretical perspectives leading to insights that are also relevant for the struggle about top-down forms of AI regulation., Competing Interests: No competing interests were disclosed., (Copyright: © 2024 Bode I and Huelss H.)

In recent years, the key role of sirtuins in the regulation of the most important cellular processes has been established. Sirtuins are involved in histone deacetylation, regulation of fat and glucose metabolism. Violations of their synthesis and secretion can induce carcinogenesis, aging and cell death. The wide range of processes in which sirtuins are involved indicates their possible role in the pathogenesis of many diseases including metabolic syndrome, neurodegenerative diseases, inflammation associated diseases and tumor growth. All of these diseases are associated with aging. In this article, we analyze the existing data on sirtuins and their role in the pathogenesis of aging, as well as their possible verification as markers for the diagnosis of age-related diseases and as targets of geriatric therapy and prevention.

The United Nations Security Council passed its first resolution on children in armed conflict in 1999, making it one of the oldest examples of Security Council engagement with a thematic mandate and leading to the creation of a dedicated working group in 2005. Existing theoretical accounts of the Security Council cannot account for the developing substance of the children and armed conflict agenda as they are macro-oriented and focus exclusively on states. I argue that Security Council decision-making on thematic mandates is a productive process whose outcomes are created by and through practices of actors across the three United Nations: member states (the first United Nations), United Nations officials (the second United Nations) and non-governmental organizations (the third United Nations). In presenting a practice-based, micro-oriented analysis of the children and armed conflict agenda, the article aims to deliver on the empirical promise of practice theories in International Relations. I make two contributions to practice-based understandings: first, I argue that actors across the three United Nations engage in reflective practices of a strategic or tactical nature to manage, arrange or create space in Security Council decision-making. Portraying practices as reflective rather than as only based on tacit knowledge highlights how actors may creatively adapt their practices to social situations. Second, I argue that particular individuals from the three United Nations are more likely to become recognized as competent performers of practices because of their personality, understood as plural socialization experiences. This adds varied individual agency to practice theories that, despite their micro-level interests, have focused on how agency is relationally constituted.

Plasminogen activation is a key event in the fibrinolytic system that results in the dissolution of blood clots, and also promotes cell migration and tissue remodelling. The recent structure determinations of microplasmin in complex with the bacterial plasminogen activators staphylokinase and streptokinase have provided novel insights into the molecular mechanisms of plasminogen activation and cofactor function. These bacterial proteins are cofactor molecules that contribute to exosite formation and enhance the substrate presentation to the enzyme. At the same time, they modulate the specificity of plasmin towards substrates and inhibitors, making a 'specificity switch' possible.
