Patente de invenção de métodos para processamento de imagens obtidas a partir de amostras preparadas 'cbnforme protocolo para reajízação de teste do cometa, particularmente corado pela prata. Este teste é amplamente utilizado para avaliação de genotoxicidade de substâncias. Há sistemas automatizados que analisam cometas corados por substâncias fluorescentes. A coloração de prata é uma técnica pouco difundida pela falta de tecnologia de análise digital automatizada e tem desempenho semelhante às técnicas com fluorescência, porém, é de baixo custo, rápida execução, não depende de microscópios de fluorescéncia e não utiliza produtos mutagênicos em seu protocolo.

INTRODUCTION: During mechanical ventilation (MV), the airways may accumulate secretions. Patients are submitted to Respiratory Therapy (RT) and tracheal aspiration when in MV, alone or associated, to eliminate these secretions. OBJECTIVE: The objective was to compare the effects of different protocols of bronchial hygiene in blood pressure, heart rate, oxygen saturation and respiratory rate of patients undergoing MV. MATERIALS AND METHODS: We conducted a prospective, randomized, controlled crossover, with intentional non-probabilistic sample in the Medical School Hospital of Marília. We included patients in invasive MV who were submitted to three different bronchial hygiene protocols: PP - physiotherapy protocol (manual chest compression and manual hyperinflation); AP - aspiration protocol; and PP + AP. Respiratory rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation and heart rate were evaluated in three moments: before (M1), immediately after (M2) and 30 minutes after (M3) for each protocol. The differences among protocols and times were assessed using ANOVA and post hoc Student Newman-Keus (p < 0.05). RESULTS: We studied eighteen 71.2 ± 13.9 year-old patients with 15.1 ± 17.7 days of MV. There were no differences among protocols. There was a significant decreasing in SBP (p = 0.0261) and DBP (p = 0.0119) from M2 to M3 in the aspiration protocol. CONCLUSION: There was a decrease of blood pressure on MV patients after 30 minutes of aspiration and no change in the other variables, and there was no difference among protocols.

Data from reference stations are widely used in GNSS (Global Navigation Satellite System) positioning, and can be used in relative positioning or network-based positioning concept. Positioning accuracy will be directly influenced by errors in signals collected in these stations. In this paper, it is aimed at evaluating these data quality using temporal series of multipath index MP1 and MP2. A statistical study of temporal series with 7 years of daily observations related to 7 stations from RBMC (Rede Brasileira de Monitoramento Contínuo) was accomplished. In order to investigate trends and seasonality a linear regression model, correlograms, and Fourier periodograms were used. We also used a harmonic adjust to identify peaks on temporal series. At last, the possible causes of seasonality found in some stations were discussed. It was also possible to identify peaks in MP values of March and October months (mainly in stations located near geomagnetic equator).
