Influence of ammonium sulphate feeding time on fed-batch Arthrospira (Spirulina) platensis cultivation and biomass composition with and without pH control.

Previous work demonstrated that a mixture of NH(4)Cl and KNO(3) as nitrogen source was beneficial to fed-batch Arthrospira (Spirulina) platensis cultivation, in terms of either lower costs or higher cell concentration. On the basis of those results, this study focused on the use of a cheaper nitrogen source mixture, namely (NH(4))(2)SO(4) plus NaNO(3), varying the ammonium feeding time (T=7-15 days), either controlling the pH by CO(2) addition or not. A. platensis was cultivated in mini-tanks at 30°C, 156 μmol photons m(-2) s(-1), and starting cell concentration of 400 mg L(-1), on a modified Schlösser medium. T=13 days under pH control were selected as optimum conditions, ensuring the best results in terms of biomass production (maximum cell concentration of 2911 mg L(-1), cell productivity of 179 mg L(-1)d(-1) and specific growth rate of 0.77 d(-1)) and satisfactory protein and lipid contents (around 30% each)

Older people's knowledge often a living centers of the third age about HIV/AIDS

Objective: To assess the knowledge of elderly participants in the Living Center for Senior Citizens on HIV / AIDS. Method: An exploratory and descriptive study with a qualitative approach, conducted through interviews with 17 elderly participants in the Living Center for Senior Citizens in Teresina-PI. The data analysis allowed us to establish three categories: knowledge of elderly HIV / AIDS; methods used by the elderly in the prevention of HIV / AIDS and health education in the prevention of HIV / AIDS. Results: The elderly hold little knowledge about HIV / AIDS, with an emphasis on prevention, transmission and susceptibility of contracting HIV at any stage of life. Few subjects reported on the use of an adequate method of prevention. Conclusion: We emphasize the importance of Health Education as a strategy to improve the knowledge of the elderly population about important aspects of HIV / AIDS, mainly with regard to the myths related to the mode of transmission

Manifestações clínicas da coinfecção entre covid-19 e dengue em adultos: revisão integrativa

Objective: to identify the evidence available in the scientific literature on the clinical manifestations of co-infection between Covid-19 and Dengue in adults. Method: integrative review, carried out in the MEDLINE/PUBMED, LILACS, IBECS, WoS and EMBASE databases, in June 2021. The descriptors "adult", "Coronavirus infections" and "dengue" with their synonyms were crossed by means of operators Booleans AND and OR. Results: 23 studies were included, with a predominance of 19 case studies (82.6%). The main clinical manifestations identified from the studies were: fever, headache, dyspnea, cough, myalgia, retro orbital pain, and skin rash. In addition to laboratory findings such as: thrombocytopenia, lymphopenia, and leukopenia. Conclusion: covid-19 and Dengue coinfection was identified and the need for an immediate search for a differential diagnosis is pointed out, in order to prevent clinical problems and reduce unexpected outcomes.Objetivo: identificar as evidências disponíveis na literatura científica sobre as manifestações clínicas da coinfecção entre COVID-19 e Dengue em adultos. Método: revisão integrativa, realizadas nas bases MEDLINE/PUBMED, LILACS, IBECS, WoS e EMBASE, em junho de 2021. Os descritores “adulto”, “Infecções por Coronavírus” e “dengue” junto aos seus sinônimos, foram cruzados por meio de operadores booleanos “AND” e “OR”. Resultados: Foram incluídos 23 estudos, predominando estudos de caso 19 (82,6%). As principais manifestações clínicas identificadas a partir dos estudos foram: febre, cefaleia, dispneia, tosse, mialgia, dor retro orbital e rash cutâneo. Além de achados laboratoriais como: trombocitopenia, linfopenia e leucopenia. Conclusão: a coinfecção COVID-19 e Dengue foi identificada e aponta-se a necessidade da busca imediata do diagnóstico diferencial, para prevenir os agravos clínicos e diminuir os desfechos inesperados

PATHOLOGIES CAUSED BY INFILTRATION IN A LONG-STAY INSTITUTION FOR THE ELDERLY: A CASE STUDY

This paper is part of an extension project aimed at renovating the Carlos Romeiro Asylum, located in Conselheiro Lafaiete, Minas Gerais, starting from an initial conception about the current state of the building. For this, it was developed a literature review on the main cause of pathologies that affect the building, infiltration and humidity damage, and others. A case study will be presented, showing the main physical deficiencies of this resting house, to propose interventions based on Material Science and Civil Engineering. Because it is a place where the construction work must be done concomitantly with the circulation of people, this project needs to be divided into stages. It is important to point out that this work may involve both recovery materials and methods, which aim to reestablish the original conditions of the damaged structures, and reinforcement, which aim to adjust the resistant capacity of the structures according to their use. The development and application of this project will bring improvements to the elderly population of the asylum, enabling better health and mobility conditions inside the space where more than sixty old people live.Este trabajo forma parte de un proyecto de ampliación que pretende reformar el Asilo Carlos Romeiro, una Institución de Larga Estancia para Ancianos situada en Conselheiro Lafaiete, Minas Gerais, a partir de una concepción inicial sobre el estado actual del edificio. Para ello, se elaboró una revisión bibliográfica sobre la principal causa de patologías que afectan al edificio, las infiltraciones y los daños por humedad, entre otros. Se presentará un estudio de caso, mostrando las principales deficiencias físicas de esta residencia de ancianos, para proponer intervenciones basadas en la Ciencia de los Materiales y la Ingeniería Civil. Al tratarse de un lugar donde las obras deben realizarse de forma concomitante con la circulación de personas, este proyecto debe dividirse en etapas. Es importante señalar que este trabajo puede implicar materiales y métodos de recuperación, que tienen como objetivo restaurar las condiciones originales de las estructuras dañadas, y de refuerzo, que tienen como objetivo ajustar la capacidad resistente de las estructuras de acuerdo con su uso. El desarrollo y aplicación de este proyecto aportará mejoras a la población anciana del asilo, permitiendo mejorar las condiciones de salud y movilidad dentro del espacio donde viven más de sesenta ancianos.

Reemergence of Oropouche Fever, Northern Brazil

Oropouche fever has reemerged in Parauapebas and Porto de Moz municipalities, Pará State, Brazil. Serologic analysis (immunoglobulin M–ELISA) and virus isolation confirmed Oropouche virus (OROV) in both municipalities. Nucleotide sequencing of 2 OROV isolates from each location indicated genotypes I (Parauapebas) and II (Porto de Moz) in Brazil

Metal biosorption onto dry biomass of Arthrospira (Spirulina) platensis and Chlorella vulgaris: Multi-metal systems

Binary and ternary systems of Ni2+, Zn2+, and Pb2+ were investigated at initial metal concentrations of 0.5, 1.0 and 2.0 mM as competitive adsorbates using Arthrospira platensis and Chlorella vulgaris as biosorbents. The experimental results were evaluated in terms of equilibrium sorption capacity and metal removal efficiency and fitted to the multi-component Langmuir and Freundlich isotherms. The pseudo second order model of Ho and McKay described well the adsorption kinetics, and the FT-IR spectroscopy confirmed metal binding to both biomasses. Ni2+ and Zn2+ interference on Pb2+ sorption was lower than the contrary, likely due to biosorbent preference to Pb. In general, the higher the total initial metal concentration, the lower the adsorption capacity. The results of this study demonstrated that dry biomass of C. vulgaris behaved as better biosorbent than A. platensis and suggest its use as an effective alternative sorbent for metal removal from wastewater.
