    The Future Impact of AI on Academic Journals and the Editorial Process

    This panel explores the emerging impact of Artificial Intelligence (AI) on academic journals and editorial processes. Scholarly publishing is on the cusp of transformation, as generative and other AI technologies challenge established norms and procedures. Advancements could either revolutionize or gradually evolve the intricate ecosystems of academic journals, responsible for validating and disseminating knowledge. How might this happen? Panelists will consider how AI could reshape editorial boards, redefine reviewer roles, and influence the academic value chain. The panel will address concerns about AI-driven review processes, biases, training data, and the integration of Human-in-the-loop AI. The panel will also examine the role of academic journals as drivers of research and innovation, with AI\u27s potential to alter communication, quality assessment, and the building blocks of archival knowledge. Highly experienced editors will share insights, concerns and predictions, engage with audience perspectives, and illuminate the challenges and opportunities that AI brings to scholarly pursuits

    Made available in DSpace on 2019-10-06T15:56:22Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-09-01The number of described anurans has increased continuously, with many newly described species determined to be at risk. Most of these new species inhabit hotspots and are under threat of habitat loss, such as Brachycephalus, a genus of small toadlets that inhabits the litter of the Brazilian Atlantic Rainforest. Of 36 known species, 22 were described in the last decade, but only 11 have been assessed according to the IUCN Red List categories, with just one currently listed as Critically Endangered. All available data on occurrence, distribution, density, and threats to Brachycephalus were reviewed. The species extent of occurrence was estimated using the Minimum Convex Polygon method for species with three or more records and by delimiting continuous areas within the altitudinal range of species with up to two records. These data were integrated to assess the conservation status according to the IUCN criteria. Six species have been evaluated as Critically Endangered, five as Endangered, 10 as Vulnerable, five as Least Concern, and 10 as Data Deficient. Deforestation was the most common threat to imperiled Brachycephalus species. The official recognition of these categories might be more readily adopted if the microendemic nature of their geographical distribution is taken into account.Instituto de Biociências Universidade Estadual Paulista (UNESP), Praça Infante Dom Henrique s/noMater Natura-Instituto de Estudos Ambientais, Rua Lamenha Lins 1080Departamento de Zoologia Universidade Federal do ParanáInstituto de Biociências Universidade Estadual Paulista (UNESP), Praça Infante Dom Henrique s/n

    Abstract Background: Many patients with congestive heart failure (CHF) have chronic kidney insufficiency (CKI) and anemia. Aims: The purpose of this review is to clarify the relationship between these three factors and to study the effect of correction of anemia in CHF and CKI. Findings: Anemia, CHF and CKI are each capable of causing or worsening each other. Thus they form a vicious circle which can result in progressive CHF, CKI and anemia. Aggressive therapy of CHF, CKI and control of the associated anemia with erythropoietin and i.v. iron can prevent the progression of CHF and CKI, reduce hospitalization, and improve quality of life. Conclusion: CHF patients are a major source of end-stage renal failure patients and deserve special attention. If treated well and early, progressive heart failure and renal failure can be prevented. Cooperation between nephrologists, cardiologists, and other internists will improve the care of all three conditions and prevent their progression

    Low-level laser (LLL) irradiation promotes proliferation of muscle satellite cells, angiogenesis and expression of growth factors. Satellite cells, angiogenesis and growth factors play important roles in the regeneration of muscle. The objective of this study was to examine the effect of LLL irradiation on rat gastrocnemius muscle recovering from disuse muscle atrophy. Eight-week-old rats were subjected to hindlimb suspension for 2 weeks, after which they were released and recovered. During the recovery period, rats underwent daily LLL irradiation (Ga-Al-As laser; 830 nm; 60 mW; total, 180 s) to the right gastrocnemius muscle through the skin. The untreated left gastrocnemius muscle served as the control. In conjunction with LLL irradiation, 5-bromo-2-deoxyuridine (BrdU) was injected subcutaneously to label the nuclei of proliferating cells. After 2 weeks, myofibre diameters of irradiated muscle increased in comparison with those of untreated muscle, but did not recover back to normal levels. Additionally, in the superficial region of the irradiated muscle, the number of capillaries and fibroblast growth factor levels exhibited significant elevation relative to those of untreated muscle. In the deep region of irradiated muscle, BrdU-positive nuclei of satellite cells and/or myofibres increased significantly relative to those of the untreated muscle. The results of this study suggest that LLL irradiation can promote recovery from disuse muscle atrophy in association with proliferation of satellite cells and angiogenesis.The definitive version is available at www.blackwell-synergy.com and www.expphysiol.org
