Morquio-like dysostosis multiplex presenting with neuronopathic features is a distinct GLB1-related phenotype

Background Morquio B disease (MBD) is a distinct GLB1-related dysostosis multiplex presenting a mild phenocopy of GALNS-related Morquio A disease. Previously reported cases from European countries carry the W273L variant on at least one GLB1 allele and exhibit a pure skeletal phenotype (pure MBD). Only a minority of MBD cases have been described with additional neuronopathic findings (MBD plus). Objectives and Methods With the aim to further describe patterns of MBD-related dysostosis multiplex, we analyzed clinical, biochemical, and genetic features in 17 cases with GLB1-related dysostosis multiplex living and diagnosed in Brazil. Results About 14 of the 17 individuals had three or more skeletal findings characteristic of Morquio syndrome. Two had no additional neuronopathic features (pure MBD) and 12 exhibited additional neuronopathic features (MBD plus). Three of the 17 cases had mild dysostosis without distinct features of MBD. Seven of the 12 MBD plus patients had signs of spinal cord compression (SCC), as a result of progressive spinal vertebral dysostosis. There was an age-dependent increase in the number of skeletal findings and in the severity of growth impairment. GLB1 mutation analysis was completed in 10 of the 14 MBD patients. T500A occurred in compound heterozygosity in 8 of the 19 alleles. Conclusion Our study extends the phenotypic spectrum of GLB1-related conditions by describing a cohort of patients with MBD and GM1-gangliosidosis (MBD plus). Targeting the progressive nature of the skeletal manifestations in the development of new therapies for GLB1-related conditions is warranted

Repercussões Respiratórias no Pós – Operatório de Câncer de Mama

Introduction: Cancer is defined as a disorderly proliferation of cells that can spread and invade tissues and/or organs throughout the body, when a genetic mutation occurs, the deoxyribonucleic acid (DNA) undergoes an erroneous change of orders on how to multiply, classified as cancer cells, named according to their multiplication speed and ability to spread to other tissues. Objective: Check the respiratory repercussions in the postoperative period of breast câncer. Method: This is a descriptive, cross-sectional study with quantitative analysis, carried out with 20 female individuals in the postoperative period of breast cancer who were undergoing treatment at a Specialty Outpatient Clinic in Montes Claros - Minas Gerais. The instruments used were the MRC scale, which assesses the level of dyspnea during physical activity, cirtometry, which assesses chest expansion, and a manovacuometer, which measures respiratory muscle strength. Results: The average age of the participants was 50.40 ± 5.50, it was observed that 90.0% of the participants feel short of breath only during intense exercises, according to the MRC scale, in the cirtometry all the subjects showed a reduction in expandability thoracic. A significant decrease in respiratory muscle strength was observed, the average percentage achieved in forced inspiration was 86.77% and in forced expiration its average percentage was 71.75%. Conclusion: It is concluded that patients with breast cancer who underwent a surgical procedure may have respiratory changes, that is, the population studied showed changes in muscle strength and changes in expansion, but there was no association between the level of chest expansion and type of surgery.Introdução: O câncer é definido como uma proliferação de células desordenadas que pode se espalhar e invadir tecidos e/ou órgãos por todo o corpo, quando ocorre uma mutação genética. Objetivo: Verificar as repercussões respiratórias no pós-operatório do câncer de mama. Método: Trata-se de um estudo de caráter descritivo, corte transversal e análise quantitativa, realizado com 20 indivíduos do sexo feminino no pós-operatório do câncer de mama que estavam em tratamento em um Ambulatório de Especialidade em Montes Claros - Minas Gerais. Os instrumentos utilizados foram a escala de MRC que avalia o nível de dispneia durante atividade física, cirtometria que avalia a expansibilidade torácica e manovacuômetro que mensura a força muscular respiratória. Resultados: A idade média das participantes foi de 50,40 ± 5,50, observou-se que 90,0% das participantes sente falta de ar só durante exercícios intensos, segundo a escala de MRC, na cirtometria todos os sujeitos apresentaram redução da expansibilidade torácica. Foi observado uma diminuição significativa na força muscular respiratória, a média percentual alcançada na inspiração forçada foi de 86,77% e na expiração forçada sua média percentual foi de 71,75%. Conclusão: Conclui-se que pacientes portadoras de CA de mama que foram submetidas a um procedimento cirúrgico podem apresentar alterações respiratórias, ou seja, a população estudada apresentou alteração de força muscular e alteração da expansibilidade, porém não houve associação entre nível de expansibilidade torácica e tipo de cirurgia. &nbsp

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

Carbon stock and humification index of organic matter affected by sugarcane straw and soil management

The maintenance of sugarcane (Saccharum spp.) straw on a soil surface increases the soil carbon (C) stocks, but at lower rates than expected. This fact is probably associated with the soil management adopted during sugarcane replanting. This study aimed to assess the impact on soil C stocks and the humification index of soil organic matter (SOM) of adopting no-tillage (NT) and conventional tillage (CT) for sugarcane replanting. A greater C content and stock was observed in the NT area, but only in the 0-5 cm soil layer (p < 0.05). Greater soil C stock (0-60 cm) was found in soil under NT, when compared to CT and the baseline. While C stock of 116 Mg ha-1 was found in the baseline area, in areas under CT and NT systems the values ranged from 120 to 127 Mg ha-1. Carbon retention rates of 0.67 and 1.63 Mg C ha-1 year-1 were obtained in areas under CT and NT, respectively. Laser-Induced Fluorescence Spectroscopy showed that CT makes the soil surface (0-20 cm) more homogeneous than the NT system due to the effect of soil disturbance, and that the SOM humification index (H LIF) is larger in CT compared to NT conditions. In contrast, NT had a gradient of increasing H LIF, showing that the entry of labile organic material such as straw is also responsible for the accumulation of C in this system. The maintenance of straw on the soil surface and the adoption of NT during sugarcane planting are strategies that can increase soil C sequestration in the Brazilian sugarcane sector
