Aims: to analyze the presence and simultaneity of behavioral risk factors for chronic non-communicable disease (NCD) in adults and the elderly. Methods: quantitative, cross-sectional and observational study. Healthy and unhealthy eating are classified according to the frequency of food consumption. Smoking is expressed by the percentage of smokers. Harmful alcohol consumption by the percentage of individuals who consumed alcoholic beverages at least once in the last 30 days. Classification of the level of physical inactivity required to practice at least 150 minutes of physical activity. Results: the sample constituted 719 people, 535 adults and 184 elderly. The behavioral risk factor reported by most adults 499 (93.3%) and elderly 156 (84.8%) was unhealthy eating. Frequency 72% higher of smoking, four times higher of harmful alcohol consumption and 10% higher of unhealthy food among adults when compared to the elderly. The simultaneity between risk factors was 39% greater in adults than in the elderly. Discussion: risk factors evaluated in this study are key aspects of the development of NCDs. Adults have 2.43 times the chance of presenting two risk factors and 7.73 times the chance of presenting three in relation to the elderly. Conclusion: To achieve more effective and differentiated results, knowing and directing measures to control behavioral risk factors, whether isolated or concurrent, requires specific knowledge.

The effect of abiotic stresses on plant C:N:P homeostasis and their mitigation by silicon

引用

The Crop Journal 2024年第2期12卷 340-353页

作者： Milton Garcia costa Renato de Mello Prado Luiz Fabiano Palaretti Jonas pereira de Souza Júnior Department of Agricultural Production Science School of Agricultural and Veterinarian SciencesSão Paulo State UniversityJaboticabalBrazil

In crop plants, various environmental stresses affect the balance of carbon, nitrogen, and phosphorus(C:N:P), leading to biochemical and physiological alterations and reductions in yield. Silicon(Si) is a beneficial element that alleviates plant stress. Most studies involving silicon have focused on physiological responses, such as improvements in photosynthetic processes, water use efficiency, and antioxidant defense systems. But recent research suggests that stressed plants facing either limited or excessive resources(water, light, nutrients, and toxic elements), strategically employ Si to maintain C:N:P homeostasis, thereby minimizing biomass losses. Understanding the role of Si in mitigating the impact of abiotic stresses on plants by regulating C:N:P homeostasis holds great potential for advancing sustainable agricultural practices in crop production. This review presents recent advances in characterizing the influence of environmental stresses on C:N:P homeostasis, as well as the role of Si in preserving C:N:P equilibrium and attenuating biological damage associated with abiotic stress. It underscores the beneficial effects of Si in sustaining C:N:P homeostasis and increasing yield via improved nutritional efficiency and stress mitigation.

Energy and Power Engineering 2024年第4期16卷 151-178页

作者： Ciro Galvão Hirdan Katarina de Medeiros costa Eduardo Guedes pereira Edmilson Moutinho dos Santos Dorel Soares Ramos Polytechnic School (EP) University of S&#227o Paulo S&#227o Paulo Brazil Institute of Energy and Environment (IEE) University of S&#227o Paulo S&#227o Paulo Brazil

This study aims to apply a methodology to analyze the regulatory obstacles for the development of thermal power plants in a country. The study uses Brazil as an application case, although mostly of the findings can be useful to other countries. It also discusses other policies and actions by the government that may contribute to the growth of natural gas-fired power plants. Using deductive and comparative research methods, the first part of this method focuses on the stage of thermoelectric power generation in Brazil. The subsequent sections present the role of the integration of gas and electricity sectors, the main obstacles to the expansion of natural-gas power generation, how the country has deal with the expansion of natural-gas power generation, as well as how other obstacles has been faced. In raising the research question, when comparing the research results of selected countries, it should be noticed the impact that the experience and lessons elsewhere have had on policies formulation on Brazil. Our conclusions pointed out that adequate policies for the natural gas-electricity Brazilian market integration make advisable the unification of electricity and natural gas agencies. We recommended developing a mathematical model to support decision-making on natural gas and electricity integration.

Objective: Evaluate pretreatment sarcopenia and anemia as prognostic factors in women undergoing treatment for cervical cancer (CC) with concurrent chemoradiotherapy (CCRT). Methods: 151 women with CC were analysed in this cohort study. Pretreatment computed tomography (CT) images were analysed to assess skeletal muscle index (SMI). Hazard ratios (HR) and multivariate Cox proportional HR were used to analyse association between low SMI, age, body mass index (BMI), haemoglobin levels, histological type, and International Federation of Gynaecology and Obstetrics (FIGO) stage with PFS and OS. Results: A total of 151 patients were included, 53 (35.1%) presented pretreatment sarcopenia;51 (34%) stage I/II and 100 (66%) stage III/IV. Among those patients in advanced stage (III/IV) 37 (70%) (p = 0.28) were sarcopenic at the beginning of treatment. Sarcopenia was associated with worse progression-free survival (PFS) and overall survival (OS) in our cohort [HR 0.97 (p = 0.01)] [HR 0.73 (p = 0.001)], as well as anemia [HR 0.73 (p = 0.001)] [HR 0.78 (p = 0.001)]. Linear regression models indicated that despite showing no association with age, neutrophil or platelet counts, sarcopenia was associated with pretreatment anemia levels (p = 0.01). After a multivariate analysis, only haemoglobin (anemia) and complete CCRT remained associated with PFS and OS. Sarcopenia and anemia were associated with worse PFS and OS in FIGO stage I/II. Conclusion: Pretreatment sarcopenia was significantly associated with low haemoglobin levels. Anemia and incomplete CCRT were independently associated with poor prognosis in women with CC. Pretreatment sarcopenia, as low SMI, was a predictor of poor prognostic in early stages of CC.

“Love Is Strong, and You＇re so Sweet”： JAGGER Is Essential for Persistent Synergid Degeneration and Polytubey Block in Arabidopsis thaliana

Molecular Plant 2016年第4期9卷 601-614页

作者： Ana Marta pereira Margarida Sofia Nobre Sara Cristina Pinto Ana Lucia Lopes Mario luis costa Simona Masiero Silvia Coimbra Departamento de Biologia Faculdade de Ciencias da Universidade do Porto Rua do Campo Alegre 4169-007 Porto Portugal Plant Functional Genomics Group Biosystems and Integrative Sciences Institute (BiolSI) 4169-007 Porto Portugal Dipartimento di BioScienze Universita degli Studi di Milano 20133 Milan Italy Present address: Institute of Plant Biology and ZUrich-Basel Plant Science Center University of ZUrich Zolikerstrasse 107 8008 Zurich Switzerland

Successful double fertilization and subsequent seed development in flowering plants requires the delivery of two sperm cells, transported by a pollen tube, into the embryo sac of an ovule. The embryo sac cells tightly control synergid cell death, and as a result the polyspermy block. Arabinogalactan proteins are highly glycosylated proteins thought to be involved in several steps of the reproductive process. We show that JAGGER, Arabinogalactan Protein 4, is an important molecule necessary to prevent the growth of multiple pollen tubes into one embryo sac in Arabidopsis thaliana. In jagger, an AGP4 knockout mutant, the pistils show impaired pollen tube blockage as a consequence of the survival of the persistent synergid. JAGGER seems to be involved in the signaling pathway that leads to a blockage of pollen tube attraction. Our results shed light on the mechanism responsible for preventing polyspermy in Arabidopsis and for safe- guarding successful fertilization of all ovules in one pistil, ensuring seed set and the next generation.

Glyphosate Dissipation in Different Soils Under No-Till and Conventional Tillage

引用

Pedosphere 2019年第6期29卷 773-783页

作者： Elena OKADA Joséluis costa Francisco BEDMAR Consejo Nacional de Investigaciones Científicas y Técnicas(CONICET) Balcarce 7620(Argentina Estación Experimental Agropecuaria Balcarce Instituto Nacional de Tecnología Agropecuaria(INTA)Balcarce 7620(Argentina Facultad de Ciencias Agrarias Universidad Nacional de Mar del PlataBalcarce 7620(Argentina

Glyphosate is the most used herbicide in Argentina, accounting for 62% of the commercialized pesticides on the market. It is used as a weed controller in no-till systems, and it is also applied to various genetically modified crops ( e.g., soybean, corn, and cotton). Although it has a high solubility in water, it tends to adsorb and accumulate in agricultural soils. The main objectives of this work were to compare the dissipation of glyphosate and the accumulation of its metabolite aminomethylphosphonic acid (AMPA) over time in three soils from agricultural areas of Argentina under long-term management with no-till (NT) and conventional tillage (CT) practices. There were no differences in dissipation between NT and CT, indicating that the glyphosate-degrading microflora was not modified by the different tillage managements. Moreover, tillage practices did not alter the general soil properties;therefore, glyphosate bioavailability was not affected by NT or CT practice. Forty percent of the applied glyphosate was degraded within the first three days in all soils, indicating a fast initial dissipation rate. However, the dissipation rate considerably decreased over time, and the degradation kinetics followed a bi-exponential (or two-compartment) kinetic model. No differences were found between tillage practices. Dissipation was not related to the microbial activity measured as soil respiration. The fast decrease in the concentration of glyphosate at the beginning of the dissipation study was not reflected in an increase in the concentration of AMPA. The estimated half-lives for glyphosate ranged between 9 and 38 d. However, glyphosate bioavailability decreases over time, as it is strongly adsorbed to the soil matrix. This increases its residence time, which may lead to its accumulation in agricultural soils.
