Morphometric properties of the tensor fascia lata muscle in human foetuses
Background: In neonatal and early childhood surgeries such as meningomyelocele repairs, closing deep wounds and oncological treatment, tensor fasciae lata (TFL) flaps are used. However, there are not enough data about structural properties of TFL in foetuses, which can be considered as the closest to neonates in terms of sampling. This studyâs main objective is to gather data about morphological structures of TFL in human foetuses to be used in newborn surgery. Materials and methods: Fifty formalin-fixed foetuses (24 male, 26 female) with gestational age ranging from 18 to 30 weeks (mean 22.94 ± 3.23 weeks) were included in the study. TFL samples were obtained by bilateral dissection and then surface area, width and length parameters were recorded. Digital callipers were used for length and width measurements whereas surface area was calculated using digital image analysis software. Results: No statistically significant differences were found in terms of numerical value of parameters between sides and sexes (p > 0.05). Linear functions for TFL surface area, width, anterior and posterior margin lengths were calculated as y = â225.652 + 14.417 Ă age (weeks), y = â5.571 + 0.595 Ă age (weeks), y = â4.276 + 0.909 Ă age (weeks), and y = â4.468 + 0.779 Ă age (weeks), respectively. Conclusions: Linear functions for TFL surface area, width and lengths can be used in designing TFL flap dimensions in newborn surgery. In addition, using those described linear functions can also be beneficial in prediction of TFL flap dimensions in autopsy studies

Methods for calculating Protection Equality for conservation planning
Protected Areas (PAs) are a central part of biodiversity conservation strategies around the world. Today, PAs cover c15% of the Earthâs land mass and c3% of the global oceans. These numbers are expected to grow rapidly to meet the Convention on Biological Diversityâs Aichi Biodiversity target 11, which aims to see 17% and 10% of terrestrial and marine biomes protected, respectively, by 2020. This target also requires countries to ensure that PAs protect an âecologically representativeâ sample of their biodiversity. At present, there is no clear definition of what desirable ecological representation looks like, or guidelines of how to standardize its assessment as the PA estate grows. We propose a systematic approach to measure ecological representation in PA networks using the Protection Equality (PE) metric, which measures how equally ecological features, such as habitats, within a countryâs borders are protected. Extending research in Barr et al. (2011), we present an R package and two Protection Equality (PE) measures; proportional to area PE, and fixed area PE, which measure the representativeness of a countryâs PA network. We illustrate the PE metrics with two case studies: coral reef protection across countries and ecoregions in the Coral Triangle, and representation of ecoregions of six of the largest countries in the world. Our results provide repeatable transparency to the issue of representation in PA networks and provide a starting point for further discussion, evaluation and testing of representation metrics. They also highlight clear shortcomings in current PA networks, particularly where they are biased towards certain assemblage types or habitats. Our proposed metrics should be used to report on measuring progress towards the representation component of Aichi Target 11. The PE metrics can be used to measure the representation of any kind of ecological feature including: species, ecoregions, processes or habitats
Current practice of blood pressure measurement in Germany: a nationwide questionnaire-based survey in medical practices
PURPOSE: Discrepancies exist between guideline recommendations and real-world practice of blood pressure (BP) measurements. The aim of this study was to assess, with a nationwide, questionnaire-based survey, the current practice of BP measurement and associated BP values in German medical practices. MATERIAL AND METHODS: A nationwide survey in German medical practices was performed in the period from 10 May 2021 to 15 August 2021. The questionnaire was divided into five sections. The current office BP (OBP) values as well as the current drug therapy were recorded. In addition, the implementation of office BP (OBP) and home BP monitoring (HBPM) was queried. For analysis, questionnaires were scanned and automatically digitised. RESULTS: A total of 7049 questionnaires were analysed, the majority of which came from general practitioners (66%) and internal medicine practices (34%). The average OBP (SD) was 140.0 (18)/82.7 (11) mmHg. 40.8% of treated patients had OBP in the controlled range, with monotherapy (34.7%) or dual combination therapy (38.2%) prescribed in most cases. OBP was taken from a single measurement in 66.3% of cases, and in 21.8% from 23 measurements. OBP was mostly measured after a rest period (87.1%) and in a separate room (80.4%). HBPM was performed in 62.3% of patients; however, in 24.9% of the participants HBP measurements were recorded once a week or less. CONCLUSION: In this nationwide survey in German medical practices, BP control remains at below 50%, while monotherapy is prescribed in around one third of patients. Moreover, office measurements and HBPM are often not performed according to current guideline recommendations

Molecular ecology meets systematic conservation planning
Integrative and proactive conservation approaches are critical to the long-term
persistence of biodiversity. Molecular data can provide important information on
evolutionary processes necessary for conserving multiple levels of biodiversity
(genes, populations, species, and ecosystems). However, molecular data are rarely
used to guide spatial conservation decision-making. Here, we bridge the fields of
molecular ecology (ME) and systematic conservation planning (SCP) (the âwhyâ) to
build a foundation for the inclusion of molecular data into spatial conservation planning
tools (the âhowâ), and provide a practical guide for implementing this integrative
approach for both conservation planners and molecular ecologists. The proposed
framework enhances interdisciplinary capacity, which is crucial to achieving the
ambitious global conservation goals envisioned for the next decade.Environment and Climate Change Canada (ECCC); Nature Conservancy of Canada; NERC Wallacea Programme Strategic Grant; an individual research contract by Fundação para a CiĂȘncia e Tecnologia; the National Research Foundation; a European Unionâs Horizon 2020 research and innovation programme under the Marie SkĆodowska-Curie grant agreement.https://www.cell.com/trends/ecology-evolution/homeam2023BiochemistryGeneticsMicrobiology and Plant Patholog
Riskâsensitive planning for conserving coral reefs under rapid climate change
Coral reef ecosystems are seriously threatened by changing conditions in the ocean. Although many factors are implicated, climate change has emerged as a dominant and rapidly growing threat. Developing a longâterm strategic plan for the conservation of coral reefs is urgently needed yet is complicated by significant uncertainty associated with climate change impacts on coral reef ecosystems. We use Modern Portfolio Theory to identify coral reef locations globally that, in the absence of other impacts, are likely to have a heightened chance of surviving projected climate changes relative to other reefs. Longâterm planning that is robust to uncertainty in future conditions provides an objective and transparent framework for guiding conservation action and strategic investment. These locations constitute important opportunities for novel conservation investments to secure less vulnerable yet wellâconnected coral reefs that may, in turn, help to repopulate degraded areas in the event that the climate has stabilized
The Diversity of Coral Reefs: What Are We Missing?
Tropical reefs shelter one quarter to one third of all marine species but one third of the coral species that construct reefs are now at risk of extinction. Because traditional methods for assessing reef diversity are extremely time consuming, taxonomic expertise for many groups is lacking, and marine organisms are thought to be less vulnerable to extinction, most discussions of reef conservation focus on maintenance of ecosystem services rather than biodiversity loss. In this study involving the three major oceans with reef growth, we provide new biodiversity estimates based on quantitative sampling and DNA barcoding. We focus on crustaceans, which are the second most diverse group of marine metazoans. We show exceptionally high numbers of crustacean species associated with coral reefs relative to sampling effort (525 species from a combined, globally distributed sample area of 6.3 m2). The high prevalence of rare species (38% encountered only once), the low level of spatial overlap (81% found in only one locality) and the biogeographic patterns of diversity detected (Indo-West Pacific>Central Pacific>Caribbean) are consistent with results from traditional survey methods, making this approach a reliable and efficient method for assessing and monitoring biodiversity. The finding of such large numbers of species in a small total area suggests that coral reef diversity is seriously under-detected using traditional survey methods, and by implication, underestimated
Unifying approaches to Functional Marine Connectivity for improved marine resource management: the European SEA-UNICORN COST Action
Truly sustainable development in a human-altered, fragmented marine environment subject to unprecedented climate change, demands informed planning strategies in order to be successful. Beyond a simple understanding of the distribution of marine species, data describing how variations in spatio-temporal dynamics impact ecosystem functioning and the evolution of species are required. Marine Functional Connectivity (MFC) characterizes the flows of matter, genes and energy produced by organism movements and migrations across the seascape. As such, MFC determines the ecological and evolutionary interdependency of populations, and ultimately the fate of species and ecosystems. Gathering effective MFC knowledge can therefore improve predictions of the impacts of environmental change and help to refine management and conservation strategies for the seas and oceans. Gathering these data are challenging however, as access to, and survey of marine ecosystems still presents significant challenge. Over 50 European institutions currently investigate aspects of MFC using complementary methods across multiple research fields, to understand the ecology and evolution of marine species. The aim of SEA-UNICORN, a COST Action supported by COST (European Cooperation in Science and Technology), is to bring together this research effort, unite the multiple approaches to MFC, and to integrate these under a common conceptual and analytical framework. The consortium brings together a diverse group of scientists to collate existing MFC data, to identify knowledge gaps, to enhance complementarity among disciplines, and to devise common approaches to MFC. SEA-UNICORN will promote co-working between connectivity practitioners and ecosystem modelers to facilitate the incorporation of MFC data into the predictive models used to identify marine conservation priorities. Ultimately, SEA-UNICORN will forge strong forward-working links between scientists, policy-makers and stakeholders to facilitate the integration of MFC knowledge into decision support tools for marine management and environmental policies
âHamburger Note zur Digitalisierung des kulturellen Erbesâ
Das Recht, insbesondere das Urheberrecht, hat groĂe Auswirkungen darauf, was von dem groĂen Reichtum unseres kulturellen Erbes im kollektiven GedĂ€chtnis verbleibt. In der digitalen Welt, in der alles Kopie und damit â im urheberrechtlichen Sinne â VervielfĂ€ltigung ist, ist auch jede Nutzung des kulturellen Erbes urheberrechtlich relevant. Auf der anderen Seite leben wir in Zeiten einer rasanten Medienentwicklung und eines Ăberflusses an Informationen, Bildern, Filmen und Texten. Umso gröĂer ist die Herausforderung, die Erinnerung an unser kulturelles Erbe wachzuhalten. Es ist also eine Frage der kulturellen Selbstbehauptung, wie die rechtlichen Rahmenbedingungen fĂŒr den Umgang mit unserem kulturellen Erbe gesetzt werden. Was nicht online gefunden werden kann, wird zunehmend verschwinden. Insofern können die Auswirkungen eines unausgewogenen Urheberrechts, das das kulturelle Erbe nicht ausreichend berĂŒcksichtigt, dramatisch sein.
Dieses Buch versammelt verschiedene VorschlĂ€ge und Ăberlegungen, wie die rechtlichen Rahmenbedingungen geĂ€ndert werden können, um eine stĂ€rkere PrĂ€senz auch des urheberrechtlich geschĂŒtzten kulturellen Erbes im Netz zu ermöglichen. Verfasst sind diese VorschlĂ€ge von Experten aus den GedĂ€chtnisinstitutionen sowie aus der Rechtswissenschaft und Politik, mithin von Autoren, die mit den internationalen Rahmenbedingungen und dem urheberrechtlichen Diskurs in Deutschland gut vertraut sind.The law, in particular copyright, has a major impact on what remains in collective memory of the great wealth of our cultural heritage. In the digital world where everything is copy and therefore - in the sense of copyright - reproduction, every use of the cultural heritage is also relevant under copyright law. On the other hand, we live in times of rapid media development and an abundance of information, images, films and texts. This is why the challenge of keeping the memory of our cultural heritage alive is all the greater. It is therefore a question of cultural self-assertion how the legal framework conditions for dealing with our cultural heritage are set. What cannot be found online will increasingly disappear. In this respect, the effects of an unbalanced copyright law that does not take sufficient account of cultural heritage can be dramatic.
This book brings together various proposals and reflections on how to change the legal framework in order to increase the presence of copyrighted cultural heritage on the Internet. These proposals are written by experts from memory institutions, law and politics, and thus by authors who are well acquainted with the international framework conditions and copyright discourse in Germany
