Efeito de inseticidas aplicados nas sementes e no sulco de semeadura, na presença do coró-da-soja, Phyllophaga cuyabana.

Abojetivou-se avalair o efeito de inseticidas aplicados nas sementes (TS) e em pulverizações no sulco de semeadura (PS), na presença do coró-da-soja, Phyllopahaga cuyabana. Em um dos experimentos, constatou-se que TS com imidacloprid (42, 60 e 90 g/ha), fipronil (50 g/ha) e thiamethoxam (70 g/ha) proporcionaram rendimentos relativo de grãos (RRG) significativamente superiores ao verificado na testemunha o coró reduziu o stand em 43,3%, enquanto nos outros tratamentos o prejuízo variou de 1,3 a 13,3%. em outro experimento, o TS com fripronil (35 g/ha), thiamethoxam (98 g/ha), imidacloprid (84 g7ha) e thiodicarbe (420 g/ha) garantiram RRG significtivamente superiores aos verificados nas respectivas testemunhas. Clorpirifós (1.344 g/ha) e endossulfam (980 g/ha) aplicados no sulco foram significativamente superiores, com referência à produção relativa de grãos, à testemunha, mas o primeiro inseticida foi superior aos segundo. Fipronil (84 g/ha) em PS e fipronil (17,5 g/ha) aplicado em TS associado a endossulfam (490 g/ha) aplicado em PS, propiciaram RRG siginificativamente superiores ao da testemunha, mas a associação dos dois inseticidas surtiu melhor efeito que o uso de fipronil, pulverizado no sulco, isoladamente. O TS com thiamethoxam (49 g/ha) associado a PS de clorpirifós (672 g/ha) garantiu RRG significativamente superior ao verfificado na testemunha

Co-evolutionary and systemic study on the evolution of emerging stem cell-based therapies

This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this record.Newly emerging therapeutic technologies have the potential to reconfigure the understanding, diagnosis, and treatment of diseases, and, consequently, to impact human health. This study integrates co-evolutionary and system-oriented perspectives to investigate factors influencing the way emerging therapies evolve in their attempt to become established medical practices. We examined the case of the use of induced pluripotent stem (iPS) cellbased therapies for age-related macular degeneration (AMD) disease. Cell therapy evolution is explored by considering their constitutive components, namely disease, biomedical technologies, and clinical practices, and observing the changes experienced by their underlying knowledge structures. We adopted a mixed methods approach that simultaneously uses publication, patent, and clinical trial data. Our results highlight the significance of the diversity of technological possibilities, the role of subjective issues in the selection of directions of search, the complementary nature between established and emerging therapies, and the tight product-process interdependencies. This study contributes to an understanding of the difficulties encountered during the emergence of new cell therapies, and the ways in which such difficulties can be circumvented to establish effective and safe cell-based clinical practices.This work was financially supported by MEXT/JSPS World Premier International Research Center (WPI) Initiative [AAR] and by MEXT/JSPS Kakenhi Grant No. 26301022 [SS] and MEXT/JSPS Kakenhi Grant No. 16K17165 [AAR].

Just preservation

We are failing to protect the biosphere. Novel views of conservation, preservation, and sustainability are surfacing in the wake of consensus about our failures to prevent extinction or slow climate change. We argue that the interests and well-being of non-humans, youth, and future generations of both human and non-human beings (futurity) have too long been ignored in consensus-based, anthropocentric conservation. Consensus-based stakeholder-driven processes disadvantage those absent or without a voice and allow current adult humans and narrow, exploitative interests to dominate decisions about the use of nature over its preservation for futurity of all life. We propose that authentically non-anthropocentric worldviews that incorporate multispecies justice are needed for a legitimate, deliberative, and truly democratic process of adjudication between competing interests in balancing the preservation and use of nature. Legitimate arenas for such adjudication would be courts that can defend intergenerational equity, which is envisioned by many nations\u27 constitutions, and can consider current and future generations of non-human life. We urge practitioners and scholars to disavow implicit anthropocentric value judgments in their work – or make these transparent and explicit – and embrace a more comprehensive worldview that grants future life on earth fair representation in humanity\u27s decisions and actions today
