RESUMEN

Erythropoietin (EPO), the primary cytokine of erythropoiesis, stimulates both proliferation and differentiation of erythroid progenitors and their maturation to red blood cells. Basal EPO levels maintain the optimum levels of circulating red blood cells. However, during hypoxia, EPO secretion and its expression is elevated drastically in renal interstitial fibroblasts, thereby increasing the number of erythroid progenitors and accelerating their differentiation to mature erythrocytes. A tight regulation of this pathway is therefore of paramount importance. The biological response to EPO is commenced through the involvement of its cognate receptor, EPOR. The receptor-ligand complex results in homodimerization and conformational changes, which trigger downstream signaling events and cause activation or inactivation of critical transcription factors that promote erythroid expansion. In recent years, recombinant human EPO (rEPO) has been widely used as a therapeutic tool to treat a number of anemias induced by infection, and chemotherapy for various cancers. However, several studies have uncovered a tumor promoting ability of EPO in man, which likely occurs through EPOR or alternative receptor(s). On the other hand, some studies have demonstrated a strong anticancer activity of EPO, although the mechanism still remains unclear. A thorough investigation of EPOR signaling could yield enhanced understanding of the pathobiology for a variety of disorders, as well as the potential novel therapeutic strategies. In this chapter, in addition to the clinical relevance of EPO/EPOR signaling, we review its anticancer efficacy within various tumor microenvironments.

RESUMEN

Due to their high content of ß-glucan, the consumption of oat products can contribute to a healthy diet. Roasting may improve sensory properties but could also affect the nutritional value of oat products. Therefore, the aim of the present study was to analyse the impact of different roasting conditions (140-180 °C, approx. 20 min) on sensory quality, health-related compounds (e.g. acrylamide, ß-glucan) and viscosities of oat kernels and flakes. Roasting resulted in oat flakes with improved sensory properties. Acrylamide formation increased with higher roasting temperatures in kernels, thin and thick flakes. Contents of fat, protein, starch and ß-glucan were not affected by roasting, whereas dietary fibre fractions were marginally modulated. Viscosities were significantly reduced with increasing roasting temperatures. The results indicate that roasting up to 160 °C is a processing technique with potential to generate oat products with improved sensory quality and favourable nutritional composition.

RESUMEN

There is an urgent need to improve human diet globally. Compelling evidence gathered over the past several decades suggests that a suboptimal diet is associated with many chronic diseases and may be responsible for more deaths than any other risks worldwide. The main components in our diet that need higher intake are whole grains, fruit and vegetables, and nuts and seeds; all of these are important sources of dietary fiber and polyphenols. The health benefits of dietary fiber and polyphenols are also supported by several decades of valuable research. However, the conclusions drawn from interventional human trials are not straightforward and the action mechanisms in improving human health are not fully understood. Moreover, there is a great inter-individual variation caused by different individual capabilities of processing, absorbing and using these compounds effectively. Data on the bioavailability and bioefficacy of hydroxycinnamic acids (HCAs) are limited when compared to other classes of polyphenols (e.g. anthocyanins). This review aims to summarize the latest research advances related to HCA bioavailability and their biological effects revealed by epidemiological data, pre-clinical and clinical studies. Moreover, we aim to review the effects of HCAs on gut microbiota diversity and function and its respective influence on host health. © 2019 Society of Chemical Industry.

RESUMEN

Debate on the hazards of advanced glycation end products (AGEs) in food has continued for many years as a result of their uncertain bioavailability and ability to bind to their receptors (RAGEs) in vivo. There are increasing evidence that free and bound AGEs have many differences in gastrointestinal digestion, intestinal absorption, binding with RAGEs, in vivo circulation, and renal clearance. Therefore, this paper compares these aspects between free and bound AGEs by summarizing the available knowledge. On the basis of the current knowledge, we conclude that it is time to differentiate free AGEs from bound AGEs in food in future studies, because they vary in many aspects that are closely related to their influence on human health. Several perspectives were proposed at the end of this review for further exploring the difference between free and bound AGEs in food.

RESUMEN

This issue of MPPA raises awareness once more of the highly specific needs of performing artists, and the specialised kind of support or assessment that will be required to optimally manage their health care needs. As reported in this issue, Kawano et al. concluded that highly expressive task-specific movements are often a normal part of the technical requirements for a dance routine, and analysing whether dancers are safe to perform these manoeuvres requires a highly trained eye and experience. Not only that, but their beliefs on how such movements affect their risk of injury may be influenced by perspectives within the dance culture (Hendry et al.). To be able to assess dancers and their injury risk requires health professionals to have substantial experience, as general health assessment measures are unlikely to be adequate to meet their highly complex performance demands (Clarke et al.). Similar experience is required in understanding the complex demands of the wide spectrum of musical performance, acting, and other artistic pursuits, including understanding strategies to help performing artists manage their workloads. Problems are highlighted with the impact of fatigue on circus (Decker et al.) and dance activities (Jarvis et al.), with work and training loads playing a role in affecting movement patterns and health status. Further research may clarify other factors contributing to fatigue in performing artists, as many issues such as travel, diet, and mood will contribute to feelings of fatigue.

RESUMEN

Este artigo é resultado do trabalho de pesquisa sobre a produção das campanhas antitabagistas de governo e sobre a forma com que foram apropriados pela população. Nosso objetivo foi avaliar como essas campanhas foram pensadas em relação aos princípios de comunicação e saúde pressupostos pelo Sistema Único de Saúde. A expectativa foi problematizar a questão numa perspectiva interdisciplinar. Analisamos documentos a partir dos preceitos teóricos e metodológicos da Semiologia dos Discursos Sociais. Concluiu-se que foram criadas campanhas alarmistas, pautadas na imputação do medo e na vigília moral, que acabaram por se distanciar da ideia de uma comunicação em saúde pública dialógica, informativa e participativa.


This article is the result of a research on the use of the concept of aversion in the production of government anti-smoking campaigns and how they were appropriated by the population. Our objective was to evaluate how these campaigns were conceived in relation to the principles of communication and health presupposed by the Unified Health System. The expectation was to problematize the issue from an interdisciplinary perspective. We analyze documents from the theoretical and methodological precepts of Semiology of Social Discourses. It was concluded that alarmist campaigns were created, based on the imputation of fear and on moral vigilance, which eventually distanced these actions from the principles of communication in dialogic, informative and participatory public health.

RESUMEN

Análise do documentário Saúde! Velho Chico, de Stella Oswaldo Cruz Penido e Eduardo Vilela Thielen, tomando-o como registro, a um só tempo, dos padrões históricos de interação com o Rio São Francisco e de alternativas capazes de construir uma relação mais sinérgica e sustentável com as águas fluviais. O filme contrapõe as metanarrativas do desenvolvimento ­ legitimadoras de intervenções como hidrelétricas, barragens, projetos de irrigação para a agricultura industrial e o controverso projeto de sua transposição ­ a formas de relação estabelecidas pelas diversas populações ribeirinhas, das quais a vida, o corpo e as culturas são construídos em estreita simbiose com o rio.


This review analyzes the documentary Saúde! Velho Chico, scripted and directed by Stella Oswaldo Cruz Penido and Eduardo Vilela Thielen, taking it as a record of the historical patterns of interaction with the Rio São Francisco (São Francisco River) and at the same time of alternatives based on the building of more synergistic and sustainable relationships with river waters. In this sense, the film contrasts the metanarratives of development ­ which legitimize interventions such as hydroelectric dams, irrigation projects for industrial agriculture as well as the controversial transfer of the São Francisco River project ­ with relationships established by the riverside populations, who have a close symbiosis between their life, body and cultures and the river.

RESUMEN

INTRODUCTION: Air pollution is one of the most important issues of our times. Air quality assessment is based on the measurement of the concentration of substances formed during the combustion process and micro-particles suspended in the air in the form of an aerosol. Microscopic atmospheric particulate matters (PM) 2.5 and 10 are mixtures of organic and inorganic pollutants smaller than 2.5 and 10 µm, respectively. They are the main cause of negative phenomena in the earth's atmosphere of Earth and human health, especially on the respiratory and cardiovascular systems. Particulates have the ability to cause permanent mutations of tissue, leading to neoplasms and even premature deaths. Nitrogen dioxide (NO2) is one of the main pollutants which arises mainly during the burning of fossil fuels. Based on numerous scientific researches, it has been proved that long-term exposure to NO2 could increase morbidity of cancer due to inflammatory processes increasing abnormal mutations. MATERIAL AND METHODS: Data available in the Polish National Cancer Registry, Chief Inspectorate for Environmental Protection and Map of Health Needs in the Field of Oncology for Poland, WHO Air Quality Guidelines 2005 were analyzed. Air pollution was also evaluated: PM2.5, PM10, NO2, and compared with lung cancer morbidity. RESULTS AND CONCLUSIONS: Based on the available data and literature, it can be concluded that in 2009-2017, on average, each Pole smoked ten cigarettes a day +/- 2. Therefore, it can be estimated that after 60 years everyone had 30 package-years of smoking, leading to a high risk of lung cancer and other smoking related diseases. Additionally air quality in Poland is not satisfactory, exceeding the standards presented in the WHO Guidelines 2005. It can be assumed that this may translate into an additional, independent continuous increase in morbidity and mortality dependent on smoking.
