Background: Mental health has been impaired and at risk due to the worldwide COVID-19 pandemic. The consequences due to confinement impacted every scenario, which directly influenced the daily routine of nurse students;in each setting students faced stressors that trigger fear, anxiety and others, since being in confinement learning of topics moved to the home, laboratory practices in hospitals were cancelled leaving the room that is uncertain up to their return to in-person activities. It is important to highlight the need for innovation and strengthening of theoretical-pedagogic aspects centered at the student’s context as a human being with their own needs and problems, who will interact with others in the continuous process of health-illness. Objective: the aim was to identify the stressors in the nurse students’ formation in the new normality post-COVID-19. Methods: Qualitative and phenomenological research with 27 participants aged 20 - 25 years, nurse students of a public university. The information collection was through four focal groups of 6-7 members each, data analysis was done according to Miles & Huberman after signed informed consent of each participant, and authorized by the chairperson of the Nurse’ career. Results: Category 1, Cumulative stressors with sub-categories 1.1 Uncertainty, 1.2 Isolation, 1.3 Invisibility, 1.4 Mockery, 1.5 Exclusion. Category 2, Expectancy states with sub-categories 2.1 Low self-esteem, 2.2 Insecurity, 2.3 Anxiety, 2.4 Depression, 2.5 Temporary leave, 2.6 Search for authenticity. Category 3, Internalization processes with sub-categories 3.1 Social rejection, 3.2 Self-censorship, 3.3 Discrediting, 3.4 Disempowerment. Category 4, Academic aspects affected with sub-categories 4.1 Deficient studying habits, 4.2 Deficient assimilations of knowledge, 4.3 Archived knowledge in the computer, 4.4 Absence of practice in previous semesters. Conclusion: Once identified the stressors in nurse students in the new normality post-COVID-1

Species from Moraceae family stand out in popular medicine and phytotherapy, have been for example used as expectorants, bronchodilators, anthelmintics and treatment of skin diseases, such as vitiligo, due to the presence of compounds with proven biological activity, as the coumarins. Coumarins are lactones with 1,2-benzopyrone basic structure, and are widely distributed in the plant kingdom, both in free form, and in glycosylated form. This work reports a literature review, describing the data of 13C NMR from 53 coumarins isolated from the family Moraceae, and data comparison between genera who presented photochemical studies, in order to contribute to the chemotaxonomy of this family.

Effectiveness of Improved Cookstoves to Reduce Indoor Air Pollution in Developing Countries. The Case of the Cassamance Natural Subregion, Western Africa

引用

Journal of Geoscience and Environment Protection 2014年第1期2卷 1-5页

作者： Candela de la Sota Julio Lumbreras Javier Mazorra Adolfo Narros luz Fernández Rafael Borge Department of Chemical and Environmental Engineering Technical University of Madrid (UPM) Spain

The Spanish NGO “Alianza por la Solidaridad” has installed improved cookstoves in 3000 households during 2012 and 2013 to improve energy efficiency reducing fuelwood consumption and to improve indoor air quality. The type of cookstoves were Noflaye Jeeg and Noflaye Jaboot and were installed in the Cassamance Natural Subregion covering part of Senegal, The Gambia and Guinea-Bissau. The Technical University of Madrid (UPM) has conducted a field study on a sample of these households to assess the effect of improved cookstoves on kitchen air quality. Measurements of carbon monoxide (CO) and fine particle matter (PM2.5) were taken for 24-hr period before and after the installation of improved cookstoves. The 24-hr mean CO concentrations were lower than the World Health Organization (WHO) guidelines for Guinea-Bissau but higher for Senegal and Gambia, even after the installation of improved cookstoves. As for PM2.5 concentrations, 24-hr mean were always higher than these guidelines. However, improved cookstoves produced significant reductions on 24-hr mean CO and PM2.5 concentrations in Senegal and for mean and maximum PM2.5 concentration on Gambia. Although this variability needs to be explained by further research to determine which other factors could affect indoor air pollution, the study provided a better understanding of the problem and envisaged alternatives to be implemented in future phases of the NGO project.

Autoantibodies in chronic hepatitis C: A clinical perspective

引用

World Journal of Hepatology 2015年第8期7卷 1074-1085页

作者： Janaína luz Narciso-Schiavon Leonardo de Lucca Schiavon Department of Internal Medicine Gastroenterology Division Federal University of Santa Catarina

Non-organ-specific autoantibodies and thyroid autoantibodies have been frequently found in chronic carriers of hepatitis C virus(HCV). With respect to endomysial antibodies and tissue transglutaminase, it is controversial whether the prevalence of glutenrelated seromarkers is higher in patients with HCV. In such cases, in addition to acknowledging any currently existing autoimmune disease, recognizing the risk of the patient developing an autoimmune disease during interferon(IFN)-based treatment must be a principle concern. From a clinical point-of-view, the presence of autoantibodies arouses suspicion that an autoimmunedisease may be present or may be precipitated by IFNbased HCV treatment. In this paper, we review the prevalence of autoantibodies in individuals with hepatitis C, the clinical significance of these autoantibodies, and the approach recommended for such situations.

Chinese Medicine 2011年第3期2卷 84-92页

作者： Alma Lorena López Velazquez María de la luz Miranda Beltrán Arturo Panduro Luis Huacuja Ruiz 不详

Knowledge of healing plants worldwide properties it has been extensively studied by their biological activities. The increasing number of plant users for healthcare originated the Research Center in Complementary Alternative Medicine, National Institute of Health (NIH) whose primary function is to be alert with a strictly scientific sense about de use of plants as main source of Complementary Alternative Medicine. It is currently about the synergy known that Is achieved on the hepatoprotective, antioxidant and hypoglycaemic activities with mixtures formed by selected plants and combined. These plants are characterized by their content of hidroxyphenolic compounds as cynarin, rosmarinic acid, flavonoids silybin and among others. Actually this kind of herbal preparations are investigated in patients with cirrhosis, type II diabetes mellitus, breast cancer and arthritis diseases. Patients with Chronic Degenerative Diseases are in state of stress and Its metabolism produces free radicals such as superoxide oO2, hydroxyl oOH and peroxynitrite highly reactive with unsaturated fatty acids of cell membranes producing lipid peroxidation. The main product of this process is the peroxyl, that when it’s reduced forms hydroxiperoxyle its decomposition forms MDA and 4-hidroxialquenal. These substances bind to R-SH2 of the aminoacids of the proteins and to the thymine of DNA, altering their biological function. Before the treatments with selected and micropulverized plants to patients, it is necessary and required in animal models demonstrate that plants do not produce toxic effects. Using mixtures of plants micropulverized is good choice because these microparticles behave as micro-releasing their constituents with increased activity and bioavailability to target cells so it will be possible to achieve greater power to control their activity and perhaps cure the disease, and provide patients an effective herbal medicine safe, free of toxic effects and low cost.

清朝灭亡后,当中华民国的成立终结了中国两千余年的封建帝制,一小群受过良好教育的精英女性离开她们安逸的家庭,卸下装饰,推翻传统中国社会对于女性的定义。为使别人听见自己的声音并将女性带入公众的视线,她们勇敢地闯入所谓的男人们的世界,并以不同的方式来讨论这样一个正在经历快速变化的国家。《女铎》是其中一种方式。作为一份妇女刊物,它最早在广学会的赞助下在上海发行。其目的是传播基督教有关道德观念、妇女责任等问题的观点,介绍资产阶级妇女地位的提升。在西方宗教和道德观的影响下,《女铎》鼓励女性走出家庭,将对于家庭事务的担忧夸大为对于社会和国家事务的担忧。围绕西方传统和新的灵感,《女铎》的中国读者们讨论诸如“新中国女性”、“女性身份”“女性特质”等概念,质疑她们在中国家庭、教育、文学和历史中扮演的角色。在其专栏和社论中,女性作家阐述了中国女性在教育方面的现有进步、在战争中扮演的角色、女性与爱国问的关系、现代婚姻风俗,以及其他与中国重建中女性新角色相关的话题。她们展示了其对于在现代中国中女性社会和政治地位的调查,并接受挑战以重写儒家传统性别角色。通过对于《女铎》的分析,本课题将展开一段有关1912年至1922年问中国女性地位变化的历史研究,并借助原文来阐明其作品是怎样反映历史和宗教背景的。笔者研究这些女性阐述妇女问题的方式,以及她们推进文化抵抗所采取的文本策略。同样,笔者也想强调女性作者、编辑、出版者是怎样在坚持使用自己的写作和出版的方式,意在打破那个时代传统和固有的文学、政治格式的情况下,将文学、文化和宗教传统化为其用的。最后,通过对于该报章文学内的分析,笔者想进一步研究印刷出版的新教传教士是怎样影响中国女性地位的变化,而且理解为什么女性读者的出版物在新教传教士的期刊、书籍,以及其他印刷媒体中占据重要位置。

Geoprocessing Applied in the Estimate of Infiltration and Surface Runoff in HPP’s Contribution Watershed

引用

Journal of Geographic Information System 2021年第6期13卷 643-659页

作者： Elizon Dias Nunes Patrícia De Araújo Romão Maurício Martines Sales Marta Pereira Da luz Institute of Socio-Environmental Studies Federal University of Goiás Goiania Brazil School of Civil and Environmental Engineering Federal University of Goiás Goiania Brazil Eletrobras Furnas Aparecida de Goiania Brazil Polytechnic School Pontifical Catholic University of Goiás Goiania Brazil

The knowledge of the hydrological regime contributes to the prediction of periods of higher or lower water supply as a function of the frequency and volume of rainfall in relation to the pedological, land cover, and land use conditions. This work aims at evaluating the spatio-temporal variability of the infiltration and runoff potential of an area formed by 4 sub-basins tributary to the São Marcos River in Cristalina (GO). The SCS/NRCS-USDA (2004) method was used, using geoprocessing resources, considering soils in dry, semi-humid and humid conditions. The estimates indicate that rainfall with an average of 6.83 mm, in the September-October transition, in the face of soils in the dry condition does not provide surface runoff. Thus, the variability of pedological characteristics associated with the various conditions of coverage and land use indicates that even the areas with lower infiltration potential begin to contribute effectively with their respective channels in the transition from October to November, when rainfall events are more frequent and significant, and the soils are already in conditions of greater humidity.
