Personality features ina sample of psychophysiological insomnia patients
Carvalho Luciane Bizari Coin de,Lopes Eliane Aversa,Silva Luciana,Almeida Marilaine Medeiros de
Arquivos de Neuro-Psiquiatria , 2003,
Abstract: The personality is the way people express themselves inside the environment they live. Sleep, quality or quantity, is a way of this physical and psychological expression of well being. Psychological factors, associated with psychophysiological insomnia (PPI) suggest an exaggerated perception of the difficulties to fall asleep. Worries, anxiety and the fear of not sleeping produce a bad sleep quality or sleep misperception. This study aims to identify personality features associated with PPI throughout Rorschach test (RT). METHOD: We studied 32 patients with PPI (22 women), between 29 and 75 years old. We excluded patients with other sleeping or psychiatric disorders. We analysed the data from PPI patients submitted to the RT and we compared our results with the standard data. RESULTS: We noticed a significant increase in global answers and a significant decrease in detailed answers; a trend of a low number of answers; great number of shape and animal answers, especially for women. CONCLUSION: The features of the PPI patient's personality were daily problems insecure and the incapability to avoid or remove them from their thought, making bedtime a time for worries to appear again and motivate insomnia.

Carvalho Luciane Bizari Coin de,Prado Lucila Bizari Fernandes do,Silva Luciana,Almeida Marilaine Medeiros de
Arquivos de Neuro-Psiquiatria , 2004,
Abstract: Sleep is basic for physical and cognitive development and some studies have suggested that there may be an association between sleep disorders (SD) and cognitive dysfunction (CD) in children. Little is known, however, about SD and cognition in 7-10-year-old children, a fact that motivated the present study. METHOD: We applied an SD questionnaire in 1180 children, 547 with SD and 633 without SD (CG), to assess cognition with a screening test (Bender Visual Motor Gestalt Test - BT). RESULTS: We observed a similar frequency of CD in the children with SD (39%) and that ot the CG (40%). The 8-year-old children with SD presented a lower prevalence of CD than the CG (SD=6%, n=6; CG=13%, n=16; p=0.04). CONCLUSION: The frequency of children with CD was equal in the study and control groups when considering the total sample (7- to 10-year-old children). In contrast to our expectations, the SD group of 8-year-old children presented a lower frequency of CD than the control group.

Materials Sciences and Applications (MSA) , 2012, DOI: 10.4236/msa.2012.36058
Abstract: In the present work a niobium based complex cubic perovskite oxide Ca2AlNbO6 ceramic was produced, characterized and studied its stability in crude petroleum environment for inert ceramic embedding for temperature sensors used in petroleum extraction. Ca2AlNbO6 ceramic powder was prepared through thermo-mechanical processing. Structural characteristics of calcined material was investigated by powder X-ray diffarctometry, which presented a single phase complex cubic perovskite structure with lattice parameter a = 7.6599 ?. Compacted discs of Ca2AlNbO6 ceramics were sintered in the temperature range 1250°C - 1350°C during 24 hours in ambient atmosphere. Microstructure of the sintered ceramics was studied by scanning electron microscopy and mechanical behavior was studied by Vicker’s microhardness testing. Ca2AlNbO6 ceramics sintered at 1350°C presented best results in terms of microstructural homogeneity and mechanical hardness. Therefore these sintered ceramics were submerged in crude petroleum for 60 days. Ceramics were taken out from the petroleum periodically and subjected to structural, microstructural and mechanical characterizations. Results showed that ceramics submerged in crude petroleum did not suffer any change at any stage of submersion. These characteristics make this material suitable for inert ceramic embedding for sensors used in petroleum extraction.

Medeiros, Jansen F;Pessoa, Felipe Arley Costa;Martins, Marilaine;
Acta Amazonica , 2010, DOI: 10.1590/S0044-59672010000400020
Abstract: in this work, the visual diagnostic methods for human filarias in the blood are evaluated. the thick blood film method is more faithful to identify the microfilariae species if compared to policarbonate membrane filtration and knott methods, especially in areas where more than one species occur, as in amazon basin. slides with mansonella ozzardi microfilariae were mounted and photographed by different diagnosis methods. the thick blood film method is much easier to see the diagnostic morphological characters as cephalic and caudal space, pattern of nucleation of the tail and tail shape that can separate the blood amazonian microfilariae species.

Cohen, Jacob Moysés;Ribeiro, Jefferson Augusto Santana;Martins, Marilaine;
Arquivos Brasileiros de Oftalmologia , 2008, DOI: 10.1590/S0004-27492008000200007
Abstract: purpose: to evaluate eye manifestations in mansonelliasis patients from coari, am, rural area on the middle amazonas river. methods: cross-sectional study consisted of evaluation of 543 subjects from coari rural area on solim?es river right margin. all subjects were submitted to blood test for microfilaria and the subjects who had a positive test also were submitted to skin biopsies and ophthalmologic examination. histopathology and pcr research for microfilaria were done on eye biopsies of suspect lesions. results: mansonella ozzardi was found in peripheral blood of 103 (18.9%) subjects. ninety-five mansonelliasis patients were examined. punctate keratitis was observed in 12 of them, nummular keratitis in one subject and sclerosing keratitis in another one. skin biopsies were negative in all subjects. conjunctival and limbal biopsies were done in five mansonelliasis patients and corneal biopsy in another three patients. conjunctival and limbal biopsies of two patients and corneal biopsy of one patient showed no microfilaria or alterations due to its presence on histopathology. pcr showed no evidence of microfilaria in the other biopsies. conclusion: association between mansonella ozzardi infection and corneal lesions with no evident etiology was observed in this study, but the lack of conclusive findings on histopathology and pcr make us doubt the corneal involvement in mansonelliasis. large studies of high mansonelliasis prevalence populations and extensive employment of microfilaria identification tests in ocular tissue are needed to evaluate the microfilaria corneal pathogenicity.
