    Here we investigate the extent to which different Aspergillus species release galactomannan (GM) in vitro. Marked variability was observed in GM reactivity between and within Aspergillus species, with A. terreus strains showing the highest GM indexes. The in vivo significance of these findings remains to be determined.O estudo objetivou investigar a liberação in vitro de galactomanana (GM) em distintas espĂ©cies patogĂȘnicas de fungos do gĂȘnero Aspergillus. Grande variabilidade foi detectada tanto intra quanto inter espĂ©cies, sendo as cepas da espĂ©cie A. terreus relacionadas aos maiores Ă­ndices de GM detectados. O significado in vivo destes achados permanece em aberto, porĂ©m merece investigação

    Artisanal Coalho cheese is a popular dairy product, widely consumed in the Northeast region of Brazil, and is produced with raw or pasteurized milk. Microbial contamination of cheeses has very important consequences, both for the dairy industry, given the potential economic losses, and for public health, due to the risk of outbreaks of foodborne diseases. The present study aimed to detect Mycobaterium spp. in Coalho cheese commercialized in the city of CaicĂł-RN Brazil, using bacterial culture and molecular diagnosis. 50 samples of Coalho cheese obtained from local street market were analyzed, 35 of which were made from raw milk (artesanal cheese) and 15 with pasteurized milk (industrialized cheese)

    Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal microorganisms and cytotoxic properties. EOs of Kielmeyera coriacea Mart. & Zucc. were analyzed by gas chromatography coupled to mass spectrometry (GC-MS). The EO from leaves is rich in sesquiterpenes hydrocarbons and oxygenated sesquiterpenes. The three major compounds identified were germacrene-D (24.2%), (E)-caryophyllene (15.5%), and bicyclogermacrene (11.6%). The inner bark EO is composed mainly of sesquiterpenes hydrocarbons and the major components are alpha-copaene (14.9%) and alpha-(E)-bergamotene (13.0%). The outer bark EO is composed mainly of oxygenated sesquiterpenes and long-chain alkanes, and the major components are alpha-eudesmol (4.2%) and nonacosane (5.8%). The wood EO is mainly composed of long-chain alkanes and fatty acids, and the major components are nonacosane (9.7%) and palmitic acid (16.2%). The inner bark EO showed the strongest antimicrobial activity against the anaerobic bacteria Prevotella nigrescens (minimum inhibitory concentration-MIC of 50 ”g mL−1). The outer bark and wood EOs showed MICs of 100 ”g mL−1 for all aerobic microorganisms tested. The EOs presented low toxicity to Vero cells. These results suggest that K. coriacea, a Brazilian plant, provide initial evidence of a new and alternative source of substances with medicinal interest

    High success and low mortality rates with non-invasive ventilation in influenza A H1N1 patients in a tertiary hospital

    <p>Abstract</p> <p>Background</p> <p>In 2009, an outbreak of respiratory illness caused by influenza A H1N1 virus occurred worldwide. Some patients required Intensive Care Unit (ICU) admission. The use of non-invasive ventilation (NIV) in these patients is controversial, as the aerosol dispersion may contaminate the environment and health-care co-workers.</p> <p>Methods</p> <p>Describe the respiratory profile, the mortality rate, and the benefit of using NIV in patients with confirmed diagnosis of influenza AH1N1 who were admitted in the ICU during the year 2009.</p> <p>Results</p> <p>A total of 1, 401 cases of influenza A H1N1 were confirmed in our hospital by real-time RT-PCR in 2009, and 20 patients were admitted to the ICU. The patients' ages ranged from 18 to 74 years (median of 42). Acute Respiratory Failure (ARF) was present in 70% of patients. The median Acute Physiology and Chronic Health Evaluation II score was 7 (range 7 to 25). Of the 14 patients who developed ARF, 85.7% needed NIV and 14% needed invasive MV at admission. Our success rate (41.6%) with NIV was higher than that described by others. The hospital mortality rate was 2.1%. When influenza A H1N1 arrived in Brazil, the disease was already on endemic alert in other countries. The population was already aware of the symptoms and the health-care system of the treatment. This allowed patients to be properly and promptly treated for influenza A H1N1, while health-care workers took protective measures to avoid contamination.</p> <p>Conclusion</p> <p>In our study we found a high success and low mortality rates with non-invasive ventilation in patients with influenza A H1N1.</p

    Molecular responses of coffee plants to drought stress.

    With the aim to investigate the molecular mechanisms underlying drought tolerance in coffee plants of C. canephora and C. arabica, qPCR experiments identified more than 80 candidate genes (CGs) presenting differential gene expression between drought-tolerant and drought-susceptible clones/cultivars cultivated under different (with or without) irrigation conditions.Resumo S04T04

    Intervenção psicolĂłgica em terminalidade e morte: relato de experiĂȘncia

    Get PDF
    O presente artigo objetivou analisar e refletir sobre a atuação do psicĂłlogo em situaçÔes de morte no contexto hospitalar, bem como sobre o processo de terminalidade e despedida para as pessoas enfermas e seus familiares. Utilizou-se relato de experiĂȘncia profissional atravĂ©s de estudo de caso. Os resultados evidenciaram reconfiguração das relaçÔes familiares nos diferentes papĂ©is e funçÔes, na perspectiva de maior autonomia. O ritual de despedida constitui-se em vivĂȘncia possibilitadora de mudanças e resgates das relaçÔes familiares, bem como de elaboração do processo de luto, tanto para o sujeito doente e famĂ­lia quanto para a equipe de saĂșde
