The strong enhancer element in the immediate early region of the human cytomegalovirus genome
The human cytomegalovirus (HCMV), a
member of the herpesvirus group, was found to
possess a strong transcription enhancer in the
immediate early gene region. Co-transfection
of enhancerless SV40 DNA with randomly fragmented
HCMV DNA yielded two SV40-like recombinant
viruses , each containing HCMV DNA fragments that
were substituting for the missing SV40 enhancer.
The two inserts , 341 and 262 bp in length , are
overlapping segments of genuine viral DNA representing
part of the 5'flanking region of the
major immedistte early gene i n HCMV. Studies
with deletion mutants showed that different nonoverlapping
subsets of the HCMV enhancer region
can substitute for the 72 bp repeats of SV40.
Transient expression assays indicated that the
HCMV enhancer is significantly stronger than the
SV40 element, activating cis-linked heterologous
promoters in a wide spectrum of cultured cells.
It appears that the HCMV enhancer is positively
regulated by viral immediate early genes
One Health continues to evolve for better health of people, animals and ecosystems
This article provides insights gained during a four-year project funded by the European Cooperation in Science and Technology (COST) named «Network for Evaluation of One Health», which brought together over 250 scientists, decision-makers and practitioners with expertise and/or interest in One Health to investigate the added value of One Health and elaborate and evaluation protocol for One Health. Here, we present our reflections on the significance of these findings for our common practice as health professionals. Two initial findings lie at the core of this analysis, namely the observation that 1) One Health integrates knowledge from various sources in a transdisciplinary way and that there are as many concepts of health as participants in a specific initiative; and 2) the nature of complex One Health problems necessitates systems thinking and consideration of emergences as a One Health initiative is implemented. An analysis of eight case studies, i.e., evaluations of different One Health initiatives, found that the capacity of an initiative to facilitate knowledge integration improves with the age of the initiative, political boundaries of any nature hinder knowledge integration, and the prevailing competitive mentality in academia may be a serious obstacle to trusted collaboration required for interdisciplinary progress. The COST project also revealed a number of important knowledge gaps, namely the need for: a scalable definition of health, balancing expert advice and citizen participation to tackle health challenges, bridging the scission between the benefits and risks arising from nature, discussing whether egoism will define the boundary to sustainable health, a biocentric social justice framework, and comparative values associated with health of people, animals, plants and ecosystems. Furthermore, methodological challenges were identified such as participatory methods that are scalable to large populations, a specific skill set to facilitate transdisciplinary research, and governing mechanisms alternative to legislation and markets. Finally, as a rather unexpected outcome, the project has revealed the tension between the academic and societal demands for infallibility and predictability versus the need for honesty, authenticity, humbleness and emotion to permit the full unfolding of human creativity
Helping to heal nature and ourselves through human-rights-based and gender-responsive One Health
Abstract: The health of our planet and humanity is threatened by biodiversity loss, disease and climate crises that are unprecedented in human history, driven by our insatiable consumption and unsustainable production patterns, particularly food systems. The One Health approach is a pathway to synergistically addressing outcomes in term of health and sustainability, but gender issues at the One Health and biodiversity nexus are largely ignored. By examining the roles and responsibilities of Indigenous and Local People, and especially women, in conserving natural resources, and the social costs of living at the Human-Animal-Environment interface under current conservation strategies, we show that women bear a disproportionate health, poverty and climate burden, despite having pivotal roles in conserving biodiversity. To mitigate risks of emerging infectious diseases, food insecurity and climate change impacts, a gender perspective has previously been proposed, but implementation lags behind. Endemic zoonotic diseases, human-wildlife conflict and environmental pollution lack gender-sensitive frameworks. We demonstrate that women can be powerful agents for change at all levels of society, from communities to businesses, and policy-making institutions, but gender inequalities still persist. We develop a framework for mainstreaming a gender-responsive and rights-based One Health approach, in order to heal ourselves and nature. Using a leverage-points perspective, we suggest a change of paradigm, from the pursuit of GDP and over-consumption, to a focus on human well-being and their reconnection with healthy environments, using a One Health understanding of nature and health. We recommend learning from Indigenous People to re-position ourselves within nature and to better conserve biodiversity. We also propose integration of gender equity in leadership, the respect of human rights, womenâs rights (access to health care, healthy food, land tenure, natural resources, education, and economic opportunities), and the rights of nature, through the implementation of gender-responsive and rights-based One Health Action Plans, at policy-making level, in the private sector and the civil society. As the COVID-19 pandemic continues to unveil deep socio-economic inequities in the wealthiest economies and the vital role of nature in supporting our health, we argue to seize this opportunity to build back better and improve resilience and sustainability by using a gender-responsive and rights-based One Health approach
A systems analysis and conceptual system dynamics model of the livestock-derived food system in South Africa : a tool for policy guidance
Global food production systems are currently under scrutiny, in particular the health, nutrition, and environmental impacts of livestock-derived food (LDF). Despite South Africaâs recent socioÂeconomic transformation and increased per-capita LDF consumption, the triple burden of malnutriÂtion persists. Policy responses to such complex problems often fail because of linear thinking with short-term goals. However, a systems approach helps identify root causes, feedback mechanisms, potential unintended consequences, and opportuÂnities for integrated, durable solutions. ParticipaÂtion in the systems-thinking process improves stakeholder understanding and buy-in. Our parÂticipatory workshop facilitated the development of a systems map for South African LDF, identifying key system elements, linkages, and nexus points. The latter included climate change, land access and management, livestock management and producÂtivity, farming systems, food safety, policy articulaÂtion, agricultural knowledge, and income. Based on these findings, and an overview of related literaÂture, we produced a conceptual system dynamics model of the LDF system. We identified key variÂables and causal relationships, vicious and virtuous loops, system archetypes, conceptual stock and flows, and links to Sustainable Development Goals. The LDF system is complex and dynamic, with a dominance of commercial enterprises across agriculture and food retail, presenting barriers for small and medium-scale individuals. Other key elements relate to population growth and urbanizaÂtion, land access, deregulation of international trade, climate change vulnerability, feed production limitations, and food safety. Our work provides a unique reference for policymakers, identifying the need for deep structural change, highlighting the possible unintended consequences, and thereby mitigating the risk of system destabilization
A Blueprint to Evaluate One Health
One Health (OH) positions health professionals as agents for change and provides a platform to manage determinants of health that are often not comprehensively captured in medicine or public health alone. However, due to the organization of societies and disciplines, and the sectoral allocation of resources, the development of transdisciplinary approaches requires effort and perseverance. Therefore, there is a need to provide evidence on the added value of OH for governments, researchers, funding bodies, and stakeholders. This paper outlines a conceptual framework of what OH approaches can encompass and the added values they can provide. The framework was developed during a workshop conducted by the âNetwork for Evaluation of One Health,â an Action funded by the European Cooperation in Science and Technology. By systematically describing the various aspects of OH, we provide the basis for measuring and monitoring the integration of disciplines, sectors, and stakeholders in health initiatives. The framework identifies the social, economic, and environmental drivers leading to integrated approaches to health and illustrates how these evoke characteristic OH operations, i.e., thinking, planning, and working, and require supporting infrastructures to allow learning, sharing, and systemic organization. It also describes the OH outcomes (i.e., sustainability, health and welfare, interspecies equity and stewardship, effectiveness, and efficiency), which are not possible to obtain through sectoral approaches alone, and their alignment with aspects of sustainable development based on society, environment, and economy
Network for Evaluation of One Health (NEOH):A systems approach for better knowledge integration
Reflecting on One Health in Action During the COVID-19 Response
The COVID-19 pandemic, a singular disruptive event in recent human history, has required rapid, innovative, coordinated and collaborative approaches to manage and ameliorate its worst impacts. However, the threat remains, and learning from initial efforts may benefit the response management in the future. One Health approaches to managing health challenges through multi-stakeholder engagement are underscored by an enabling environment. Here we describe three case studies from state (New South Wales, Australia), national (Ireland), and international (sub-Saharan Africa) scales which illustrate different aspects of One Health in action in response to the COVID-19 pandemic. In Ireland, a One Health team was assembled to help parameterise complex mathematical and resource models. In New South Wales, state authorities engaged collaboratively with animal health veterinarians and epidemiologists to leverage disease outbreak knowledge, expertise and technical and support structures for application to the COVID-19 emergency. The African One Health University Network linked members from health institutions and universities from eight countries to provide a virtual platform knowledge exchange on COVID-19 to support the response. Themes common to successful experiences included a shared resource base, interdisciplinary engagement, communication network strategies, and looking global to address local need. The One Health approaches used, particularly shared responsibility and knowledge integration, are benefiting the management of this pandemic and future One Health global challenges
