Hélvecio Cardoso Póvoa, Richard Raphael Borges Tavares Vieira, Elias Sobreira Sathler, Isabela Nardoni Bernardes, Rafael Batista Ferreira, Mário Henrique Couto Lima, Thiago Sande Miguel, Nayrton Kalys Cruz dos Anjos, Lamara Laguardia Valente Rocha, Daniel Almeida da Costa
Journal of Biosciences and Medicines (JBM) , 2018, DOI: 10.4236/jbm.2018.61005
Abstract: Objective: To determine the main microbial genotypes and their antimicrobial resistance and susceptibility profile commonly used in the treatment of oncologic patients with febrile neutropenia, carried out through the review of the clinical histories of the patients’ medical records at the Hospital do Cancer de Muriaé-Fundacao Cristiano Varella. Methods: Quantitative research, determined the susceptibility profile of microorganisms in patients with febrile neutropenia from April 2007 to April 2008 by reviewing clinical histories of patients’ medical records at the referred hospital. Results: Of the total of 8 patients evaluated with Gram-negative microorganisms, 50% of the patients were female and 50% were male. Of the 18 patients evaluated with Gram-positive microorganisms 66% were female and 34% male. Gram-positive bacteria are prevalent and cause around 60% of documented bacteremias, although Gram-negative bacteria are more common in febrile neutropenic patientes. Conclusion: Exaggerated use of antimicrobials in hospitalized patients leads to the suppression of drug-sensitive microorganisms from the intestinal flora and promotes the persistence and growth of resistant bacteria. The antibiotic should be used in a curative manner with other therapeutic measures with the determined bacterial infection.
Study of Effects of Photodynamic Therapy (PDT), in Scar-Induced Skin Wounds in Rats Wistar: The New Clinical Perspective for Ulcers  [PDF]

Modern Research in Inflammation (MRI) , 2017, DOI: 10.4236/mri.2017.61001
Abstract: Photodynamic therapy today is becoming an important role in the healing of lacerated tissues, since it has therapeutic resources capable of accelerating this process. One treatment option is the clinical phototherapy, and Photodynamic Therapy (PDT) is being widely used. This study aims to evaluate the effect of PDT on the healing of skin wounds in rats. We used a sample of 39 male rats Wistar divided into three groups, a control, a PDT-treated green and red with the last PDT. After 24 hours before the surgical incisions, PDT was used in both groups for 6 minutes and was evaluated in histological level, the inflammatory reaction and the repair process. The results showed that the granulation tissue was more developed in the irradiated group than in the control group and the amount of chronic inflammatory cells (monocytes, macrophages, lymphocytes and plasma cells) predominated with green phototherapy. The epithelialization in the wound margins and scarring with better quality occurred with red PDT (640 nm), which the higher deposition was of collagen. However, phototherapy not collimated of 640 nm (red) resulted in better anti-inflammatory effects. Given these answers with phototherapy not collimated green (525 nm) and red (640 nm), we conclude that the use of these wavelengths is possible with benefits, mainly with red LED.
Sponsor-investigator-relationship: challenges, recent regulatory developments and future legislative trends  [PDF]

Health (Health) , 2011, DOI: 10.4236/health.2011.312128
Abstract: Correct definition and management of sponsor- investigator relationship is of central importance for planing and executing clinical trials. During the last decade, there have been numerous modifications of guidelindes, international and national legislations and regulations. This implicated various alterations and shifts of essential responsibilities and tasks relating to the investigator, sponsor or sponsor-investigator what raised financial, clinical and ethical issues. First experiences with these new regulations and legislations are discussed together with international differences and their impacts on clinical trials. Regarding non-commercial trials and institutional sponsorship, there are still open organizational and legal questions after national implementation of the Europeam Clinical Trials Directive in 2004, although various approaches have been suggested in recent years in Europe. Current trends and controversies are discussed as well. A literature review was performed summarizing recent experiences with current legislations and risen controversies of these new legislations showing impact on future trends.
Quinine levels in patients with uncomplicated falciparum malaria in the Amazon region of Brazil
Vieira, José Luiz Fernandes;Borges, Larissa Maria Guimar?es;Nascimento, Margareth Tavares Silva;Gomes, Andreza de L.S.;
Brazilian Journal of Infectious Diseases , 2008, DOI: 10.1590/S1413-86702008000500001
Abstract: we examined the plasmatic concentrations of quinine in patients with uncomplicated falciparum malaria in an endemic area of the amazon region in brazil in a prospective clinical trial, in which a standard three-day course of oral quinine plus doxycycline was used. we measured the quinine in the plasma samples on days 0 and 3by high performance liquid chromatography. the mean concentration of quinine was 6.04 ±2.21 μg/ml in male patients and 5.98 ±1.95 μg/ml in female patients. no significant differences in quinine concentration were observed between these two groups. all samples collected before starting treatment were negative for quinine. this information could help in the development of strategies for the rational use of antimalarial drugs in brazil.
Treatment of Bullfrog Farming Wastewater in a Constructed Wetland  [PDF]
Fernanda de Freitas Borges, Lúcia Helena Sipaúba Tavares
Journal of Water Resource and Protection (JWARP) , 2017, DOI: 10.4236/jwarp.2017.96038
Abstract: The aim of this study was to install and assess the efficiency of a constructed wetland for wastewater treatment from bullfrog farming (Lithobates catesbeianus) at fattening growth phase. Water detention time was not controlled since wastewater input flow varied according to the biomass of animals maintained in stalls. The study was divided into two phases, with higher and lower bullfrog biomass respectively for phase I and II. A higher removal of nitrite, biochemical oxygen demand, and thermotolerant coliforms was observed at phase I whereas a higher removal of turbidity, nitrate, total phosphorus, total suspended solids, total dissolved solids, and chlorophyll a occurred at phase II. Wastewater treatments using constructed wetland systems with high organic load require a higher water detention time for a better load removal. The treatment effect was positive since this wastewater flowed directly into fishponds or streams, which might promote eutrophication. Thus, wastewater treatment is essential to minimize the impact caused by frog farming on receiving water bodies, promoting the sustainability of this activity in Brazil.
The Efferent System or Olivocochlear Function Bundle - Fine Regulator and Protector of Hearing Perception
Raphael Richard Ciuman
International Journal of Biomedical Science , 2011,
Abstract: The efferent system of the ear possesses several distinct functions, in particular noise protection, mediation of selective attention and improvement of signal to noise ratio. It also supports adaptation and frequency selectivity by modification of the micromechanical properties of outer hair cells. There are many differences in anatomy and physiology between the medial and lateral olivocochlear system suggesting that they are functionally separate systems. The efferent system is affected by inner ear stressors, e.g. noise, ototoxic drugs, and might play a key role in tinnitus generation and maintenance. The anatomy, physiology and its realtionships to inner ear pathologies are discussed in this review article.
Capillary-gravity waves: The effect of viscosity on the wave resistance
Denis Richard,Elie Raphael
Physics , 1999, DOI: 10.1209/epl/i1999-00112-5
Abstract: The effect of viscosity on the wave resistance experienced by a 2d perturbation moving at uniform velocity over the free surface of a fluid is investigated. The analysis is based on Rayleigh's linearized theory of capillary-gravity waves. It is shown in particular that the wave resistance remains bounded as the velocity of the perturbation approches the minimun phase speed, unlike what is predicted by the inviscid theory.
Planck Constraints on Monodromy Inflation
Richard Easther,Raphael Flauger
Physics , 2013, DOI: 10.1088/1475-7516/2014/02/037
Abstract: We use data from the nominal Planck mission to constrain modulations in the primordial power spectrum associated with monodromy inflation. The largest improvement in fit relative to the unmodulated model has \Delta\chi^2~10 and we find no evidence for a primordial signal, in contrast to a previous analysis of the WMAP9 dataset, for which \Delta\chi^2~20. The Planck and WMAP9 results are broadly consistent on angular scales where they are expected to agree as far as best-fit values are concerned. However, even on these scales the significance of the signal is reduced in Planck relative to WMAP, and is consistent with a fit to the noise associated with cosmic variance. Our results motivate both a detailed comparison between the two experiments and a more careful study of the theoretical predictions of monodromy inflation.
