Introduction: In the last few years, there has been a growth in the number of cases of people with HIV/AIDS aged 50 years and older. This is explained by the inclusion of antiretroviral therapy, increased survival of patients as well as by the growth in the number of infected people in this age group. Objective: To analyze the association between sociodemographic and clinical characteristics with the QOL of people aged 50 years or older living with HIV/AIDS. Methods: Quantitative, cross-sectional study conducted in the outpatient clinic of a reference hospital in Natal, Brazil. The sample consisted of 50 subjects, aged over 50, seropositive for HIV and with cognitive conditions to answer the interview. Authors used sociodemographic and clinical evaluation tools and the WHOQOL-HIV BREF scale. Results: Sociodemographic: respondents’ average age was 57.32 years, 58% male, 38% brown, 26% incomplete primary education, 46% single, 56% retired, 70% with a monthly income of 1 to 2 minimum wages and 70% Catholic. Clinical: 60% have a partner without the diagnosis of HIV/AIDS;62% had not been hospitalized previously;66% did not have opportunistic infections;40% indicated that there was a change in the physiological sexual function after the onset of the disease. Quality of life: people living with HIV/AIDS had low scores in QOL domains. When associating sociodemographic and clinical aspects, it was observed that they had associations with QOL, especially in regard to education, income, religion, change in sexual function and feelings. Conclusion: The spiritual domain was highlighted with the best performance, collaborating to facing, hope and resilience of HIV/AIDS.

Objective: To identify in the literature the theories used by nursing professionals in the care of people with an ostomy. Method: It’s about an integrative review of the literature used in the LILACS, BDENF, PubMed Central, CINAHL, Web of Science and SCOPUS database. Results: The sample was made of 18 publications. Most of them were studies published in the last five years (44.4%), international publications (72.2%), published in international periodicals (66.7%), with level IV of evidence (83.3%). It was identified in the articles that the nursing theories were shown as the most used by the nurses in the care of people with an ostomy (55.5%), followed by the theories borrowed from psychology (38.9%) and, finally, the theories borrowed from pedagogy (22.2%). Conclusion: The nurses are using the assistance nursing models with a higher frequency to subsidize their surveys, as well as borrowed theories, mostly being performed and published internationally and with a low evidence level, highlighting the need of studies with a higher stringent methodology and, beyond this, analysis research of the used theories.

Objective: Cardiovascular diseases are the most common causes of morbidity and the leading cause of mortality in the world scenario, accounting for about 20% of all deaths in individuals over 30 years. It has attributed this to the increase in the company’s exposure to risk factors. It identifies cardiovascular risk factors in the nursing team and compares the cardiovascular risk by Framingham score among professionals of middle and upper working in a referral hospital in cardiology. Method: Cross-sectional quantitative study was conducted in 2014, in a reference hospital in cardiology located in Recife/Pernambuco, Brazil. Data of cardiologic risk factors were collected from 82 nursing team members, comprised of technical, auxiliary nurses, and nurses between 30 and 74 years of age. The cardiovascular risk level was evaluated by the Framingham Score. Data were organized and analyzed by means of the SPSS, with descriptive statistics and Student-t test for the continuous variables. Results: Family history, stress and sedentary life style were the prevalent risk factors in more than half of the professionals. Only 5.23% of the technical and auxiliary nurses had a high risk score for cardiovascular event. Conclusion: The data indicates a low cardiovascular risk for these professionals and the presence of risk factors that can be modified. Health surveillance of these professionals is necessary in order to avoid a change to a risk of greater vulnerability.

Influence of steel jacket thickness on the RC bridges' seismic vulnerability

引用

Journal of Traffic and Transportation Engineering(English Edition) 2019年第1期6卷 15-34页

作者： bertha Olmos José Manuel Jara Gerardo Gómez Guillermo Martínez Department of Civil Engineering Universidad Michoacana de San Nicolas de Hidalgo

The seismic demands of bridges subjected to strong earthquakes are mostly concentrated on piers. The main objective of this study is to assess the seismic vulnerability of retrofitted bridges with steel jackets. It analyzes the influence of the steel jacket thickness on the seismic capacity and demand of bridges. The bridges in study have two simple supported spans with superstructure composed by AASHTO type girders and a substructure formed with one circular pier over a stiff foundation. They are located on the Pacific coast of Mexico that is a zone of high seismicity. The bridges seismic capacity are evaluated through nonlinear static analyses and the shear force and displacement demands were determined using capacity spectra with a group of 10 real accelerograms from a subduction source. The response spectra were scaled to several peak ground accelerations(PGA) with the aim to estimate four damage scenarios linked each one to a probability of exceedance in a specific period, for return periods in the range of 72-3500 years that represent service level and maximum considered earthquake. Results show that the confining effect provided by the steel jackets substantially improves the seismic performance of the bridges piers. The increase of jacket thickness guides to important increments on columns base shear capacity, and the influence of the steel jacket thickness depends on the limit state and bridge slenderness ratio.

Melatonin Avoids Anatomofunctional Changes Associated to Aging in a Rat Model

引用

Advances in Aging Research 2014年第4期3卷 318-325页

作者： bertha Prieto Gómez cruz Reyes-Vázquez Mireya Velázquez-Paniagua Departamento de Fisiología Facultad de Medicina UNAM México D.F. México

Melatonin is a hormone synthesized and released primarily by the pineal gland. Its secretion fol-lows a circadian rhythm with a peak overnight. Its secretion is initiated approximately to the three months of age and continues to rise during the childhood. Previous to the puberty there is a de-crease of melatonin secretion that continues until the old age. Melatonin has effects in the body and acts through at least four mechanisms: membrane receptors, orphan nuclear receptors, calmodulin and free radicals. It has been suggested that aging can be a consequence of the oxidation of cells that eventually become vulnerable to injury and die. This work reviews the antioxidant effects of melatonin in a rodent model, on the formation of free radicals, on the MAP2 protein expression and on the electrophysiology of the hippocampus at different ages. The results indicate that melatonin maintains in a “best” state to the experimental animals compared to controls. It suggests the use of melatonin as a therapy to prevent or delay the aging effects on the cells.

Melatonin changes the electrical spontaneous activity of hippocampal rat neurons at different ages

引用

Advances in Aging Research 2014年第1期3卷 29-34页

Melatonin, the pineal indole is characterized by being a compound that crosses all cell membranes and which has been attributed to several mechanisms of action. Among these it is the ability to reduce free radicals, thereby reducing the potential aging and cell death. Studies in different age Wistar rats have shown that chronic application of melatonin, in the hippocampus, reduces the concentration of free radicals and keeps its architecture. This study showed that melatonin increases the firing rate and favors the presence of bursting activity in animals of different ages. It is suggested that melatonin conserved hippocampal cells in good anatomical and physiological condition probably as a result of the elimination of free radicals.

Trypanosoma cruzi,the causative agent of Chagas disease, interacts with molecules in the midgut of its insect vector to multiply and reach the infective stage. Many studies suggest that the parasite binds to midgut-specific glycans. We identified several glycoproteins expressed in the intestine and perimicrovillar membrane (PMM) of Triatoma (Meccus) pallidipennis under different feeding conditions. In order to assess changes in protein-linked glycans, we performed lectin and immunoblot analyses on glycoprotein extracts from these intestinal tissues using well-characterized lectins, and an antibody, which collectively recognize a wide range of different glycans epitopes. We observed that the amount and composition of proteins and glycoproteins associated with different glycans structures changed over time in the intestines and PMM under different physiological conditions. PMM extracts contained a wide variety of glycoproteins with different sugar residues, including abundant high-mannose and complex sialylated glycans. We propose that these molecules could be involved in the process of parasite-vector interactions.

Assessing the Influence of Phosphorus Fertilization on the Growth and Yield of Maize/Soybean Intercrop by Analyzing Nitrogen Uptake

引用

Natural Resources 2024年第8期15卷 189-210页

作者： bertha Magombo Chunjie Li Benjamin Kolie Department of Resource and Environmental Science and Plant Protection China Agricultural University Beijing China Institute of Geographic Sciences and Natural Resources Research Chinese Academic of Science Beijing China Department of Resources and Environmental Management University of the Chinese Academy of Sciences Beijing China

Intercropping, particularly the combination of maize and soybeans, has been widely recognized for its potential to improve nitrogen uptake and promote sustainable agriculture. This study examines the patterns of nitrogen uptake in maize and soybean intercropping systems under different growth stages and phosphorus fertilization levels and investigates the influence of nitrogen uptake on growth parameters such as plant height, leaf area, and biomass accumulation in the maize/soybean intercrop under different phosphorus fertilization regimes. The study also collected chlorophyll samples at different growth stages of maize in monoculture and intercropping with maize or soybean. The results showed that plant height was greater in V10 in both fertilized and unfertilized treatments for intercropped maize and soybean, and chlorophyll concentration was higher in VT intercropped maize. The results also showed a higher accumulation of biomass. Understanding the growth dynamics of these plants in monoculture and intercropping systems and the impact of fertilization practices is crucial for optimizing crop productivity and sustainability in agricultural systems.

Natural Resources 2024年第7期15卷 173-187页

作者： bertha Magombo Chunjie Li Benjamin Kolie China Agricultural University Department of Resource and Environmental Science and Plant Protection Beijing China Institute of Geographic Sciences and Natural Resources Research Chinese Academic of Science Beijing China Department of Resources and Environmental Management University of the Chinese Academy of Sciences Beijing China

The study of Nitrogen fixation, uptake, and leaching at different soil depths in the co-cultivation of maize and soybean under phosphorus fertilization is important for sustainable agriculture. This study was conducted in Quzhou, Hebei Province, China, with MC812 maize and Jidou12 soybean varieties. Soil samples were taken from each plot to create a composite sample. The results show that nitrogen concentration varies at different depths and is higher in all treatments between 40 and 100 cm. Incorporating intercropping of maize and soybeans into farming practices can lead to more sustainable and environmentally friendly agriculture in China.
