Growth and genetic parameters of progenies of Cordia trichotoma in the juvenile phase
Increasing the productive potential of native species is a challenge for forest genetic improvement. Progeny tests are efficient tools to determine the reproductive capacity of individuals and to assist with the selection of superior genotypes. Cordia trichotoma (Vell.) Arrab. ex Steud, is a native species of commercial interest due to its high potential for sawn wood. The performance of seedling production from different progenies was the objective of this work. Seeds were collected from 34 matrices selected phenotypically and georeferenced in the region of Lavras - MG. The experiment was conducted in a completely randomized design with 4 replications of 12 plants. Germination after 70 days of sowing, survival and height at 170 days after germination were evaluated. Height and genetic parameters were estimated according to mixed REML / BLUP models using the Selegen software model 82. Progeny 104 (70.8%) was superior in germination and progenies 86 (35.42%), 92 (35.42%) and 111 (43.75%) had the highest survival rates. Height shows high values for the individual additive genetic variation coefficient (49.18%) and genotypic variation coefficient between progenies (24.59%) and moderate values of heritability in the restricted individual sense (0.45) and heritability within progenies (0.38). Due to high values for the coefficient of genotypic variation and moderate values of heritability, there is a potential for height improvements. Progenies 104 stand out in the germination and the progenies 86, 92 and 111 in the seedlings survival). Regarding height, progeny 95 is the only one that stands out negatively
Nasal polyposis : more than a chronic inflammatory disorder : a disease of mechanical dysfunction : the São Paulo position
Introduction The importance of our study lies in the fact that we have demonstrated the occurrence of mechanical dysfunction within polypoid tissues, which promotes the development of polyps in the nasal cavity. Objective To change the paradigm of nasal polyposis (NP). In this new conception, the chronic nasal inflammatory process that occurs in response to allergies, to pollution, to changes in the epithelial barrier, or to other factors is merely the trigger of the development of the disease in individuals with a genetic predisposition to an abnormal tissue remodeling process, which leads to a derangement of the mechanical properties of the nasal mucosa and, consequently, allows it to grow unchecked. Data Synthesis We propose a fundamentally new approach to intervening in the pathological process of NP, addressing biomechanical properties, fluid dynamics, and the concept of surface tension. Conclusion The incorporation of biomechanical knowledge into our understanding of NP provides a new perspective to help elucidate the physiology and the pathology of nasal polyps, and new avenues for the treatment and cure of NP
AS CONDUTAS DO PROFISSIONAL DE SAÚDE FRENTE A PARADA CARDIORRESPIRATÓRIA
Objective: To discuss, through the existing literature, the conduct of health professionals in the face of cardiopulmonary arrest. Methods: This is a qualitative integrative literature review. The search for works involved in the research was carried out in the following databases: SCIELO, LILACS, BDENF and MEDLINE, using the health sciences descriptors: "Hospital care", "Cardiorespiratory arrest" and "Emergency". The inclusion criteria were: published between 2013 and 2023, with free access to full texts, articles in Portuguese, English and Spanish and related to the theme. Exclusion criteria were: duplicate articles, incomplete articles, abstracts, reviews, debates, articles published in event proceedings and unavailable in full. Results: It is worth noting that the health professional who is in charge of identifying CPR should perform CPR maneuvers as soon as they identify that the victim has no pulse. Conclusion: This study concluded that CPR used to be one of the main causes of death in the world, but now that there are protocols and care strategies, it is no longer as frequent a cause of death as it once was.Objetivo: Discutir por meio da literatura existente acerca das condutas do profissional de saúde frente a parada cardiorrespiratória. Métodos: Trata-se de uma revisão integrativa da literatura de caráter qualitativo. A busca dos trabalhos envolvidos na pesquisa foi realizada nas seguintes bases de dados: SCIELO, LILACS, BDENF e MEDLINE, a partir dos descritores em ciências da saúde: “Assistência hospitalar”, “Parada cardiorrespiratória” e “Urgência”. Os critérios de inclusão foram: publicados no período entre 2013 e 2023, cujo acesso ao periódico era livre aos textos completos, artigos em idioma português, inglês e espanhol e relacionados a temática. Critérios de exclusão foram: artigos duplicados, incompletos, resumos, resenhas, debates, artigos publicados em anais de eventos e indisponíveis na íntegra. Resultados: Destaca-se que o profissional de saúde que estiver a frente da identificação da PCR deve realizar as manobras de RCP a partir do momento que ele identificar que a vítima não possua pulso. Conclusão: O presente estudo concluiu que a PCR antigamente era uma das principais causas de morte no mundo, visto que atualmente existem protocolos e estratégias de cuidado ela não é mais uma causa frequente de morte como antes
Survey of Third-Party Parenting Options Associated With Fertility Preservation Available to Patients With Cancer Around the Globe
Purpose: In the accompanying article, “Analysis of Fertility Preservation Options Available to Patients With Cancer Around the Globe,” we showed that specific fertility preservation services may not be offered at various sites around the world because of cultural and legal barriers. We assessed global and regional experiences as well as the legal status of third-party reproduction and adoption to serve as a comprehensive international data set and resource for groups that wish to begin oncofertility interventions. Methods: We provide data on the legalities of third-party assisted reproductive technologies and other family-building options in the 28 oncofertility-practicing countries surveyed. Results: We found regional and country differences that will be important in the development of tailored resources for physicians and for patient brochures that are sensitive to these local restrictions and cultural norms. Conclusion: Because many patients first consult Web-based materials, the formal assessment of the availability of these options provides members of the global oncofertility community with data to which they might otherwise not have ready access to better serve their patients

Caderno de pós-graduação em direito: novas tendências do direito ambiental
Pioneirismo sempre foi uma característica do UniCEUB; outra característica
é a evolução permanente. A Instituição sempre acompanhou a evolução
tecnológica e pedagógica do ensino. Isso se coaduna com a filosofia institucional
que é a de preparar o homem integral por meio da busca do conhecimento e
da verdade, assegurando-lhe a compreensão adequada de si mesmo e de sua responsabilidade
social e profissional. Destarte, a missão institucional é a de gerar, sistematizar
e disseminar o conhecimento visando à formação de cidadãos reflexivos e empreendedores,
comprometidos com o desenvolvimento socioeconômico sustentável.
E não poderia ser diferente. Com a expansão do conteúdo acadêmico que se
transpassa do físico para o virtual, do local para o universal, do restrito para o difundido,
isso porque o papel não é mais apenas uma substância constituída por elementos
fibrosos de origem vegetal, os quais formam uma pasta que se faz secar sob a forma de
folhas delgadas donde se cria, modifica, transforma letras em palavras; palavras em textos;
textos em conhecimento, não! O papel se virtualiza, se desenvolve, agora, no infinito,
rebuscado de informações. Assim, o UniCEUB acompanha essa evolução. É dessa forma
que se desafia o leitor a compreender a atualidade, com a fonte que ora se entrega à leitura
virtual, chamada de e-book.
Isso é resultado do esforço permanente, da incorporação da ciência desenvolvida
no ambiente acadêmico, cujo resultado desperta emoção, um sentimento de beleza de
que o conteúdo científico representa o diferencial profissional.
Portanto, convido-os a leitura desta obra, que reúne uma sucessão de artigos que
são apresentados com grande presteza e maestria; com conteúdo forte e impactante; com
sentimento e método, frutos da excelência acadêmicaOrganizadores: Gabriel R. Rozendo Pinto, Leandro Soares Nunes, Naiara Ferreira Martins, Paulo Victor Lima, Pedro Almeida Costa, Pietro Pimenta, Rodrigo Gonçalves Ramos de Oliveir
Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
