Ferreira, Léslie Piccolotto;Guerra, Juliana Ranzani;Loiola, Camila Miranda;Ghirardi, Ana Carolina de Assis Moura;
International Archives of Otorhinolaryngology , 2012, DOI: 10.7162/S1809-97772012000300002
Abstract: introduction: studies to understand the vocal profile of a population are important to plan collective health measures. the prevalence of vocal symptoms can be indicative of vocal disorder and must be investigated to support measures to prevent vocal diseases. aim: to characterize vocal symptoms in college students and their possible causes, and to analyze the association between hoarseness, vocal fatigue, phlegm, and burning in the throat with the possible causes mentioned. method: prospective study of 517 students who answered a questionnaire about their general heath and vocal symptoms and causes. we used the study of proportions, measures of central tendency, and a chi-square test to associate the presence of symptoms and possible causes. results: symptoms most often mentioned: dry mouth (21%), dry throat (18.2%), phlegm (17.9%). causes most often cited: high respiratory disease (39%), intense voice use (24%), smoking (24%). hoarseness was associated with heavy use of voice and high respiratory disease; vocal fatigue with intense voice use, stress, and digestive problems; burning in the throat with intensive voice use, high respiratory disease, and pollution; phlegm with smoking, and upper respiratory and digestive problems. conclusion: not only do aspects of health and the voice interfere with its production, the external environment and habits influence the vocal symptoms of this population as well.

Melo, Rosineia M.;Corrêa, Vivian F. S.;Amorim, Ana Carolina L.;Miranda, Ana Luisa P.;Rezende, Claudia M.;
Journal of the Brazilian Chemical Society , 2007, DOI: 10.1590/S0103-50532007000100020
Abstract: the leaf essential oil of eugenia uniflora l. (myrtaceae) was extracted by clevenger apparatus and analysed by gas chromatography-mass spectrometry (gc-ms). the leaves were collected and immediately extracted for five consecutive days at 9:00 am and 2:00 pm. no variance in the oil yields were observed in the period. furanodiene and its rearrangement product, furanoelemene (or curzerene, 50.2%), b-elemene (5.9%) and a-cadinol (4.7%) were identified as the most abundant compounds. gc-olfatometry (gc-o) associated to aroma extract dilution analysis (aeda) allowed the identification of nine active aroma compounds, where furanodiene (along with furanoelemene, fd 1024), b-elemene (fd 256) and (e,e)-germacrone (fd 256) were characterized as the main impact aroma compounds in the odor of this essential oil. those substances were collected through a sniffing port adapted on the gc allowing to obtain a typical essence of pitanga as indicated by comparative olfatometric analysis.

Journal of the Brazilian Chemical Society , 2009, DOI: 10.1590/S0103-50532009000200018
Abstract: the chemical profile of the essential oils obtained from the leaves and flowers of hyptis passerina mart., a rare species of the brazilian cerrado, has been determined for the first time. analyses by gc-ms showed sesquiterpenes as major compounds. β-epi-acorenol (35.7% and 32.8%, respectively from leaf and flower essential oils), was isolated and identified by 1d and 2d nmr. the flower-derived oil presented a higher concentration of hydrocarbon and oxygenated monoterpenes, while the leaf-oil was richer in diterpenes. the global odour impressions of both oils were given by direct analysis and gc-ms-o and were characterized as herbaceous with tea notes, and green, cooked and woody impressions for leaf-oil; herbaceous, with spicy, woody and minty notes for flower-oil. β-epi-acorenol, spathulenol, β-caryophyllene, and caryophyllene oxide were relevant for the odour-activity of both oils, as well as minor constituents, such as linalool. the antimicrobial activity was investigated by means of agar diffusion disc method and contact bioautography, against gram-positive and negative bacteria and yeast. both oils presented to be bioactive against the tested microorganisms with significant inhibition level.

Abstract: oropharyngeal candidiasis is the most common opportunistic fungal infection in individuals infected with human immunodeficiency virus. cd4+ lymphocytes count and the quantification of viral rna in blood plasma have been found to be the main markers of hiv disease progression. the present study was conducted to evaluate candida sp. diversity in the oral cavity of hiv-infected patients and to determine whether there was association of cd4+ cell count and viral load with asymptomatic oral candida carriage. out of 99 hiv-positive patients studied, 62 (62.6%) had positive culture for candida (oral carriage) and 37 patients (37.4%) had candida negative culture (no oral carriage). the etiologic agents most common were c. albicans and c. tropicalis. the range of cd4+ was 6-2305 cells/mm3 in colonized patients and 3-839 cells/mm3 for non-colonized patients, while the viral load was 60-90016 copies/ml for colonized patients and 75-110488 copies/ml for non colonized patients. the viral load was undetectable in 15 colonized patients and in 12 non colonized patients. our results showed that there was no significant difference of the variables cd4+ cell count and viral load between oral candida carriage and no oral candida carriage patients.

Abstract: Background. The present study explores the influence of the host’s age and gender upon the inflammatory infiltrate. We aimed to quantify the inflammatory infiltrate caused by cysticercosis, which is related to aging, in the heart and in the encephalon. Methods. 75 autopsy protocols with cysticercosis diagnosis from department of pathology at a university hospital from 1970 to 2008 were reviewed. Two groups were formed: elderly with cysticercosis and nonelderly with cysticercosis. We used KS-300 (Kontron-Zeiss) software for morphometric analysis of the inflammation. Results. The elderly had an average of cysticerci, whereas the non-elderly had parasites. The non-elderly group with cysticercosis had significantly more inflammation, both cardiac and encephalic, than the elderly group. The elderly females with cysticercosis had more cardiac and encephalic inflammation. Conclusions. In this study, we showed that the non-elderly had significantly more cardiac and encephalic inflammation than the elderly, and that such inflammatory infiltrate decreases with age and depends upon the evolutionary stage of the cysticercus. Furthermore, there are differences concerning gender in the intensity of the inflammatory response due to cysticerci in the heart and brain parenchyma during senescence. Even during this period, women continue to have a more intense response to the parasitosis. 1. Introduction Understanding the changes occurring within an aging immune system is essential if public health authorities are to be equipped to deal with an aging population. Specifically, knowledge of altered immune responses to infectious agents is required if rational clinical interventions are to be tailored to these aging individuals [1]. Aging is a continuous and slow process that compromises the normal functioning of various organs and systems [2]. As the population ages, there is growing interest in understanding host-parasite interaction and eventual prevention of chronic parasitic diseases, including cysticercosis, in elderly individuals. Cysticercosis is emerging as a serious public health problem in many poor countries in Latin America, Africa and Asia. Although theoretically easy to control, and declared eradicable, cysticercosis remains neglected in most endemic countries [3]. This parasitosis may be asymptomatic or it may cause a variety of clinical manifestations depending on the number, location, and stage of cysticercus lesions. Pleomorphic disease is a result of the presence of the parasite itself (cysticerci), of the inflammatory process that surrounds the larvae,

Abstract: objective: to compare the maternal-fetal clinical intercurrences and the effectiveness of treatment in the different clinical forms of hypertensive syndromes during pregnancy (hsp). methods: medical records of 200 pregnant women with hsp were reviewed to appraise fetal intercurrences, classification of the hypertensive syndrome and use of antihypertensives. results: of the 200 patients analyzed, 85 (42.5%) were controls; 32 (16%) presented gestational hypertension (gh), 67 (33.5%) had pre-eclampsia (pe), 6 (3%) had chronic hypertension and 10 (5%) cases had pe superimposed chronic hypertension (psch). the lowest values for gestational age, weights of the newborn and for the apgar index were observed in the patients with pe and psch. treatment did not alter the apgar index in relation to control and non-treated gh patients. patients with pe presented the lowest gestational age and the smallest apgar index when compared to controls. conclusion: introduction of an antihypertensive therapy during gestation was of fundamental importance for health improvement and pressure control of the pregnant woman with hsp. nevertheless, it has been of little help for prevention of perinatal intercurrences. this was substantiated by the absence of improvement in the gestational conditions between the treated group when compared to the non-treated. medication did not significantly improve the maternal-fetal blood flow and consequently in the birth condition of the child.

Abstract: We report here on the characterization of a cDNA library from seeds of Jatropha curcas L. at three stages of fruit maturation before yellowing. We sequenced a total of 2200 clones and obtained a set of 931 non-redundant sequences (unigenes) after trimming and quality control, ie, 140 contigs and 791 singlets with PHRED quality $10. We found low levels of sequence redundancy and extensive metabolic coverage by homology comparison to GO. After comparison of 5841 non-redundant ESTs from a total of 13193 reads from GenBank with KEGG, we identified tags with nucleotide variations among J. curcas accessions for genes of fatty acid, terpene, alkaloid, quinone and hormone pathways of biosynthesis. More specifically, the expression level of four genes (palmitoyl-acyl carrier protein thioesterase, 3-ketoacyl-CoA thiolase B, lysophosphatidic acid acyltransferase and geranyl pyrophosphate synthase) measured by real-time PCR proved to be significantly different between leaves and fruits. Since the nucleotide polymorphism of these tags is associated to higher level of gene expression in fruits compared to leaves, we propose this approach to speed up the search for quantitative traits in selective breeding of J. curcas. We also discuss its potential utility for the selective breeding of economically important traits in J. curcas.

Abstract: a composi??o da dieta pode interferir diretamente na homeostase energética. no metabolismo energético, a via de oxida??o e a termogênese induzida pela dieta s?o diferenciadas pela propor??o de macronutrientes da dieta. neste sentido, a dieta hiperprotéica émais termogênica que as dietas hiperglicídicas e hiperlipídicas, enquanto que as dietas ricas em carboidrato parecem ser mais termogênicas que as ricas em lipídio, mas os resultados ainda s?o controversos. em rela??o à ingest?o calórica, a composi??o da dieta pode estimular ou inibir a mesma, de acordo com a palatabilidade dos alimentos e o grau de sacia??o e saciedade, relacionadas às quantidades de carboidrato, proteína e lipídio da mesma. uma hierarquia tem sido relatada para a capacidade dos macronutrientes em induzir saciedade em que a proteína é o mais sacietógeno ao contrário dos lipidios, que s?o os menos sacietógenos. de modo geral, ainda há discrepancias entre os estudos, em rela??o ao papel regulador dos macronutrientes em componentes do gasto energético e na ingest?o calórica, devido às diferen?as metodológicas como amostra, tempo de exposi??o à dieta, densidade calórica e conteúdo calórico total da mesma. desta forma, o presente trabalho tem como objetivo analisar as evidências científicas mais consistentes a respeito do papel modulador da composi??o da dieta na termogênese induzida pela dieta e na ingest?o calórica, para melhor entendimento da preven??o e controle da obesidade pela interven??o dietética.
