Biofilms of Candida albicans serotypes A and B differ in their sensitivity to photodynamic therapy

Candida albicans is classified into different serotypes according to cell wall mannan composition and cell surface hydrophobicity. Since the effectiveness of photodynamic therapy (PDT) depends on the cell wall structure of microorganisms, the objective of this study was to compare the sensitivity of in vitro biofilms of C. albicans serotypes A and B to antimicrobial PDT. Reference strains of C. albicans serotype A (ATCC 36801) and serotype B (ATCC 36802) were used for the assays. A gallium-aluminum-arsenide laser (660 nm) was used as the light source and methylene blue (300 mu M) as the photosensitizer. After biofilm formation on the bottom of a 96-well microplate for 48 h, each Candida strain was submitted to assays: PDT consisting of laser and photosensitizer application (L + P+), laser application alone (L + P-), photosensitizer application alone (L-P+), and application of saline as control (L-P-). After treatment, biofilm cells were scraped off and transferred to tubes containing PBS. The content of the tubes was homogenized, diluted, and seeded onto Sabouraud agar plates to determine the number of colony-forming units (CFU/mL). The results were compared by analysis of variance and Tukey test (p < 0.05). The two strains studied were sensitive to PDT (L + P+), with a log reduction of 0.49 for serotype A and of 2.34 for serotype B. Laser application alone only reduced serotype B cells (0.53 log), and the use of the photosensitizer alone had no effect on the strains tested. It can be concluded that in vitro biofilms of C. albicans serotype B were more sensitive to PDT.

Eventos adversos em terapia medicamentosa em Unidade de Terapia Intensiva - UTI

Due to the complexity and instability of clinical conditions of ICU patients, the drug therapy applied in this type of environment requires a combination of several prescribed drugs, which is a favorable condition for drug interaction, toxic synergism and possible iatrogenia. In the possible universe of ICU occurrences, this study aimed at identifying and evaluating the incidence of adverse events in drug therapy at the Intensive Care Therapy Service (SETI) in wards I and II. It is a cross-sectional, descriptive, prospective and quantitative study conducted from August to September, 2011 in the Intensive Care Service of the Botucatu School of Medicine University Hospital - UNESP. The population consisted of fifteen clinical nurses, including those in the Improvement and Volunteer Internship Programs, who contributed to the investigation after signing an informed consent form and according to approval by the Research Ethics Committee number 10711/CE - FMB. The data were entered on a form and analyzed. Results showed that, on average, 8.9% of events/day occurred, and the highest frequency was observed on August 04, 2011. 63% and 22% were respectively observed in the morning and afternoon shifts, and 15% in the night shift. 48% of these were due to administration time errors, followed by drug prescription and dispensation errors, with percentages of 22% and 18%, respectively. Antibiotics showed the highest frequency of adverse events - 18%, which was followed by 13% for anticoagulant, 11% for antiemetic and 10% for antiulcerative drugs. As regards the occurrence of adverse events related to hospitalization time, the highest frequency occurred in patients who were hospitalized for 10 days. Concerning the ratio between reported events and the number of items in the prescription, the highest frequency of events was related to prescriptions with 20 items...

Efeitos da ação central do peróxido de hidrogênio na ingestão de água, na excreção renal de água e eletrólitos e na expressão de Fos induzidos pela estimulação colinérgica da área sptal medial

A área septal medial (ASM), situada no prosencéfalo, está envolvida na regulação cardiovascular e no controle do balanço hidroeletrolítico. Esta área é rica em receptores colinérgicos e a ativação dos mesmos induz ingestão de água, natriurese e antidiurese. A ASM também envia projeções aos núcleos paraventricular (NPV) supra-óptico (NSO), os quais contêm os neurônios que secretam vasopressina e ocitocina. Existem evidências experimentais demonstrando que as espécies reativas de oxigênio podem participar do controle de respostas fisiológicas. Resultados recentes de nosso laboratório demonstraram que uma espécie reativa de oxigênio, o peróxido de hidrogênio (H2O2), injetado no ventrículo lateral (VL) reduz a ingestão de água e a resposta pressora induzida por ANG II e carbacol (agonista colinérgico) também injetados no VL. Por isso, o presente estudo teve como objetivo estudar os efeitos da injeção de H2O2 na ASM sobre a ingestão de água, sobre a excreção renal de água e eletrólitos e sobre a expressão da proteína c-Fos no NSO produzidos pela injeção de carbacol também na ASM. Para realizar este trabalho, foram utilizados ratos com cânulas de aço inoxidável implantadas na ASM. A ingestão de água e a excreção renal de água e eletrólitos foram estudadas em ratos que receberam injeções de H2O2 (5 mol/0,5 μl) ou PBS (veículo, 0,5 l) na ASM e, após um minuto, injeção de carbacol (4 nmol/0,5 l) ou salina (NaCl 0,15 M / 0,5 l) também na ASM. A ingestão de água induzida pelo carbacol, através da estimulação colinérgica, foi menor nos ratos que receberam a injeção prévia de peróxido de hidrogênio (8 ± 2,0 ml / 1 h, p<0,05) comparado àqueles que receberam veículo, também na ASM (16,6 ± 1,9 ml / 1 h, p<0,05). Além disso, houve diferença significativa na ingestão de água dos ratos + salina, grupo controle... (Resumo completo, clicar acesso eletrônico abaixo)

Apocinina versus diapocinina como inibidor da produção de peróxido de hidrogênio e ácido hipocloroso por neutrófilos ativados

Apocynin has been used as an efficient inhibitor of the multi-enzymatic complex NADPH oxidase in many experimental models involving phagocytic and nonphagocytic cells. The mechanism of inhibition has been linked with the previous activation of apocynin through the action of cellular peroxidases leading to the formation of a dimeric oxidation product, diapocynin. In this study we compared apocynin with pure diapocynin regarding their effects as scavenger of hydrogen peroxide and hypochlorous generated by glucose/glucose oxidase and myeloperoxidase respectively, and as inhibitors of the production of hydrogen peroxide and hypochlorous acid by activated neutrophils. The production of hydrogen peroxide was measured by the oxidation of the fluorescent substance Amplex Red and the production of hypochlorous acid by was measured as taurine-chloramine derivative using the chromogenic substrate 3,3’,5,5’- tetramethylbenzidine (TMB). Neutrophils (1 x106 cells/mL) were pre-incubated in PBS buffer supplemented with 1 mM calcium chloride, 0.5 mM magnesium chloride, 1 mg/mL glucose and 5 mM taurine in the presence or absence of inhibitors. The reactions were triggered by adding the soluble stimulus Forbol Miristate Acetate PMA or zymosan and incubated by additional 30 minutes. We found that pure diapocynin was not better than apocynin regarding its scavenger and inhibitory properties. These results suggest that the formation of diapocynin is not essential for the action of apocynin as inhibitor of NADPH oxidase activation

Avaliação da viabilidade econômica da implantação de uma usina de triagem e compostagem na cidade de Rio Claro-SP

The question of the solid waste is without a doubt one of the biggest problems faced for the world-wide population in the present time, resulting in the call “collapse of the garbage”. In this direction that appears the composting, in the scope of the treatment of organic waste origin, that in Brazil, approximately correspond 50% of the generated volume. However, the rare plants of selection and composting (UTC) existing at least do not obtain auto-to support themselves, increasing to each day the number of deactivations, almost always related the financial questions. In this direction, the present research brings the analysis of the economic viability of the implantation of a UTC for the city of Rio Claro-SP, relating it with the thick organic composition sales, for the cultures of vegetables cultivated in a ray of 30 km of the study area. For in such a way, they had been carried through, calculations concerning the regional demand for organic composition, and the verification of the implantation costs and operation of the plant. The reached results had been the flow of box for the first year of functioning of the UTC, as well as the break-even point between the gotten expenditures and prescriptions. From this relation investment profitability, it was verified that the UTC is presented impracticable under the economic point of view.

Síntese, incorporação e liberação prolongada do tetradecapeptídeo OGP em celulose bacteriana

Este trabalho apresenta o estudo de dois sistemas de liberação prolongada, microemulsão e lipossomas, contendo peptídeo regulatório de fatores de crescimento, “osteogenic growth peptide” OGP, para aplicação em regeneração óssea. A base de adsorção para estes sistemas de liberação foi a celulose bacteriana (CB) produzida pela bactéria Gluconacetobacter xylinus. Foi escolhida devido às suas propriedades físicas e químicas, tais como como alta resistência à corrosão química, bio absorção, biocompatibilidade, porosidade e ainda boa resistência mecânica, o que a torna um biopolímero com grande potencial a ser explorado pela ciência biomédica. Estudos in vitro foram realizados para avaliar o perfil de liberação do peptídeo dos diferentes sistemas de liberação prolongada. O peptídeo OGP foi sintetizado pelo método da fase sólida (estratégia SPFS Fmoc); foi purificado e caracterizado por HPLC, espectrometria de massas e análise de aminoácidos e, em seguida, marcados com 5,6 carboxifluoresceína (CF) para análise por espectroscopia de fluorescência. O peptídeo marcado foi incorporado aos sistemas de liberação no momento do respectivo preparo, foram adsorvidos na CB por um período de 72h, seguido de sua liberação prolongada em sistema fechado de fluxo constante contendo tampão PBS pH 7,4, por um período de 24h. Após a análise da liberação, observou se que o sistema que obteve melhor resultado foi a microemulsão, sendo sua liberação prolongada nas primeiras 6,5 h, liberando 21,5% do valor teórico de peptídeo incorporado, seguido de uma liberação constante a partir desse período. Dessa forma, tem se que a microemulsão pode ser um sistema promissor para liberação prolongada do OGP em processos de regeneração óssea

O valor mágico do olhar no capítulo 35 do livro I do 'Opus agriculturae' de Paládio

Blood is one of the most important and powerful elements in magical and religious symbology. As it is an essential substance for animal survival, it does not sound strange that through the ages blood has been given many significant symbolic values (both positive and negative). It can provide life, protection and prosperity in the same proportion that it can cause calamities, destruction and even death. In Opus agriculturae, a farming treatise written by Palladius (V AD), more specifically in Book I, Chapter 35, the author presents prescriptions to protect farms against scourges and climatic phenomena. He mentions some procedures in which blood is a fundamental component in the success of the prescriptions. The aim of the present article is to identify any magic power associated with these practices, their specific symbolic value, especially when related to menstrual blood and to other feminine elements with some magical or religious value. An evaluation is also made of the extent of these symbologies in the context of other practices and situations linked not only to agricultural magic, but to religion and to the ritual practices of other communities, whether in ancient times or not.
