Preliminary Study of the Gastric Acidity in Thoroughbred Horses at Rest after Enteral Administration of Esomeprazole Magnesium (Nexium)

The regulation of gastric secretion is of crucial importance to the equilibrium of the gastroenteric system. Despite the large number of factors involved in the causes of peptic illnesses, pH = 4 is considered the threshold between physiologic and deleterious effects of stomach acid secretion. With the aim of maintaining pH greater than 4, proton-pump inhibitors, such as esomeprazole magnesium (NEXIUM), have shown excellent results in the control of acid secretion. Aimed at examining the action of this drug in the control of pH levels of gastric secretion in thoroughbreds, a single dose of 40 or 80 mg of esomeprazole magnesium was administered daily, and pH was determined serially for 5 consecutive days. The results obtained corroborated the efficacy of esomeprazole magnesium in the control of gastric pH at both doses tested, with 100% of the mean pH being greater than 5. Moreover, no statistical difference was noted between the two doses tested.

Qualidade de vida de pessoas com úlceras venosas atendidos no ambulatório de um hospital universitário

Descriptive study aimed to analyze the quality of life (QOL) of patients with venous ulcers (UV) outpatient clinic of a university hospital in Natal / RN. The aim of the study population was composed of 50 patients with UV treated at the cardiology clinic of a university teaching hospital at the tertiary level. The study was approved by the Ethics Committee of the Federal University of Rio Grande do Norte (Protocol 279/09). Data collection was performed over a period of two months by the very a masters degree and an academic nursing through the application of a form concerning the socio-demographic, clinical, and health care, and the instruments WHOQOL and WHOQOL - old. The data were analyzed with SPSS 15.0, using descriptive and inferential statistics presented in the form of tables, charts and graphs. Of the surveyed, female predominance, age range 59 years, Catholic, low education, married, with up to 03 children, not working, retired, or with occupations requiring long periods in one position, wage income of up to 02 minimum wages, inadequate sleep, patients with chronic venous insufficiency and other chronic diseases such as diabetes and hypertension, were taking medications for treatment, being a minority to IVC. In patients with predominant only one injury, time of injury up to five years, inadequate rest, pain, edema and lesions colonized. The assistance the UV patients began treatment of the injury until four months after the onset of the ulcer, and services primary health care most wanted, access to angiologist by reference form, commuted by public transportation, received support regarding the treatment of injuries. The topical product most used in the lesion was healing, and few were using compression therapy. respondents suffer discrimination in society, showed changes in quality of life after the occurrence of ulcer in relation to leisure, pain, restriction of social / school / transportation; barring employment / financial / social ladder; Physical appearance / discrimination and restriction of domestic activity. These changes were related to the time of injury and found that the more chronic injury is the most negative changes occur in their QV (ρ = 0.000). Analyzing the characteristics of QV measured by the WHOQOL-bref, we found for the two general questions they are dissatisfied with their health (ρ = 0.023) and all areas have significant difference compared with the worst QV have the injury of more than 5 years (ρ = 0.000). The QV measured by the WHOQOL-old, we found that these patients had no changes from the time of injury. We conclude that the QV of patients with UV was considered unsatisfactory when compared to the time of injury on more than 5 years which shows that the quality of life worsens with time the chronic UV.

Qualidade de vida em gestantes no contexto na Estratégia Saúde da Família

The pregnancy as a process in woman's life requires several biological, psychological, relational and socio-cultural changes for the preparation for motherhood. By modifying its capacity and, at the expense of these factors, it is observed that the physical, social and emotional problems experienced by women during pregnancy can affect their quality of life, especially related to health. It had as objectives of this research verifying the quality of life of women in the context of the Family Health Strategy in a municipality in Paraíba, in order to characterize the sociodemographic aspects, lifestyle habits, and obstetric care of pregnant women and to characterize the fields of quality of life of pregnant women according to the WHOQOL-bref. This is a descriptive exploratory study with cross-sectional and quantitative approach. The population consisted of 120 pregnant women in primary care in the municipality of Sousa-PB. Data collection occurred over a period of two months by the own master's degree student and two nursing students in applying a standard form about sociodemographic characteristics, and obstetric care and the WHOQOL-bref instrument. The data collected were organized into an electronic database of the Microsoft Excel application, coded, tabulated and presented in tables, charts and figures with their respective percentage distributions. Of the surveyed, the predominant were age group of 20 to 25 years, Catholic religion, with a steady partner, low education, no employment, wage income of 01 minimum wage. As for the data and obstetric care, almost all had never aborted and reported to the care received as excellent. The most frequent complaints were back pain and in lower abdomen. Regarding quality of life according to the WHOQOL-bref, dissatisfactions that predominated in the areas were in the physical pain and discomfort, sleep, rest, energy and fatigue. In the psychological domain, body image and appearance, memory, concentration and negative feelings. In the field of social relationships, sexual activity and the environment domain, the greatest dissatisfaction with facets scored: financial resources, leisure opportunities and transport. It is concluded that the quality of life of the users interviewed were deemed unsatisfactory for these facets, indicating that assistance to this target audience should be done comprehensively and holistically, in order to accommodate the affected facets to improve the quality of life pregnant women attended in primary care

Temporal analysis of the reduction in gas emission in areas of mechanically-harvested sugarcane using satellite imagery

The primary objective of this study was to estimate the amount of gas not emitted into the air in areas cultivated with sugarcane (Saccharum officinarum) that were mechanically harvested. Satellite images CBERS-2/CCD, from 08-13-2004, 08-14-2005, 08-15-2006 and 08-16-2007, of northwestern São Paulo State were processed using the Geographic Information System (GIS)-IDRISI 15.0. Areas of interest (the mechanically-harvested sugarcane fields) were identified and quantified based on the spectral response of the bands studied. Based on these data, the amount of gas that was not emitted was evaluated, according to the estimate equation proposed by the Intergovernmental Panel on Climate Change (IPCC). The results of 396.65 km(2) (5.91% for 2004); 447.56 km(2) (6.67% for 2005); 511.54 km(2) (7.62% in 2006); and 474.60 km(2) (7.07% for 2007), calculated from a total area of 6,710.89 km(2) with sugarcane, showed a significant increase of mechanical harvesting in the study area and a reduction of gas emissions of more than 300,000 t yr(-1).

Structural characteristics and forage mass of Tifton 85 pastures managed under three post-grazing residual leaf areas

The experiment was carried out on Cynodon spp cv. Tifton 85 pastures grazed by sheep under rotational stocking, with the objective of evaluating the structural characteristics as well as the forage mass of the pastures subjected to three grazing intensities in successive cycles. Treatments were composed of three residual leaf area indices (rLAI; 2.4; 1.6 and 0.8), allocated in completely randomized blocks with seven replications, totaling 21 experimental units. Tiller population density, pasture height, leaf area index, forage morphological composition and pasture forage mass were evaluated. The rLAI modified the tiller population density, which increased linearly with decrease in the rLAI of the pastures. Dry masses of leaf blade, stem and dead material were inferior when the rLAI imposed were lower, which resulted in differentiated forage production among the treatments. Tifton 85 pastures grazed by sheep in rotational stocking under tropical conditions with different rLAI show a modified sward structure over successive grazing cycles, mainly by alteration in the height and LAI of the plants at pre-grazing and by light interception post-grazing, which change the tiller population density. The residual leaf area index of 1.6 is the most suitable for pasture management for being equivalent to the heights of entrance and exit of animals on and from paddocks of 33 and 19 cm, respectively, which avoid great accumulation of dead material and excessive stem elongation, in addition to ensuring tillering in the sward.

Analysis of land use and occupancy in permanent preservation areas according to the hydrography of Ribeirão Água Fria - Bofete, SP - Brazil

Os conflitos de uso são determinados pelas ocupações inadequadas do solo, como é o caso de ocupação do solo dentro de áreas de preservação permanente. O presente trabalho teve como objetivos determinar as classes de uso do solo e se há conflitos dentro de áreas de preservação permanente ao longo da rede de drenagem da microbacia do Ribeirão Água Fria, município de Bofete (SP). Situa-se geograficamente entre as coordenadas: 48°09'30 a 48°18'30 de longitude WGr., 22°58'30 a 23°04'30 de latitude sul com uma área de 15.242,84 ha. O mapa de uso do solo foi elaborado por meio da interpretação diretamente na tela do computador de imagem digital de satélite. Nos dados orbitais, a área de estudo está inserida no quadrante A, da imagem TM/Landsat-5, órbita 220, ponto 76, passagem de 8/09/2007. O Sistema de Informação Geográfica empregado foi o Cartalinx. As áreas de conflito da microbacia foram obtidas a partir do cruzamento entre os mapas de uso do solo e de APPs. Os resultados permitiram concluir que mais da metade da área (51,09%) está ocupada por pastagens, reflexo de solos arenosos e de baixa fertilidade. Constatou-se, ainda, que apesar de quase metade da microbacia estar coberta com algum tipo de vegetação (48,78% de mata natural/reflorestamento), possui aproximadamente um terço das áreas de preservação permanente utilizadas inadequadamente por pastagens (88,15%), reflorestamento (10,42%) e solo exposto (1,43%), totalizando 343,07 ha de áreas conflitantes em um total de 993,26 ha de APPs.

Prevalence of Lettuce mosaic virus - common strain on three lettuce producing areas from São Paulo State

O LMV ocorre em todo o mundo e é considerado um dos patógenos mais importantes para a cultura da alface. de acordo com a habilidade em contornar os genes de resistência mo1¹ e mo1² encontrados em alface, os isolados de LMV podem ser dividos em dois sub-grupos: LMV-Most, capazes de contornar a resistência propiciada por estes genes e de serem transmitidos pela semente nestas cutivares, e LMV-Common, que não são capazes de causar sintomas nestes cultivares, além de serem transmitidos pela semente somente em cultivares suscetíveis. Para avaliar a ocorrência destes dois tipos de isolados de LMV foram coletadas, durante 2002-2005, amostras de alface com sintomas de mosaico em áreas de produção de alface comercial das regiões de Campinas, Mogi das Cruzes e Bauru no estado de São Paulo. O RNA total foi utilizado para detecção por RT-PCR utilizando-se oligonucleotídeos universais para LMV que amplificam a porção N-terminal variável da capa protéica, localizada no terminal 3´do genoma. As amostras positivas foram analisadas por um segundo primer que amplifica um fragmento da região central (CI-VPg) do genoma viral. Um total de 1362 amostras foram avaliadas, tendo sido detectado o LMV em 504 amostras (37,29%). O LMV-Common prevaleceu em variedades suscetíveis (77,3%). O LMV-Most foi encontrado frequentemente associado a variedades portadoras do gene de tolerância mo1¹. Apesar da existência dos LMV-Most capazes de contornar a resistência em alface, estes não predominam em nossa condições.

Proposta de zoneamento ambiental visando a proteção dos recursos hídricos de uma bacia hidrográfica

One of the most important natural resources for sustaining human life, water, has been losing the basic requirements of quality and quantity sufficient enough to attend the population due to water contamination'problems, often caused by human beings themselves. Because of this, the sources of this resource are often located in remote places of the natural environment to ensure the quality of the water. However, when urban expansion began to occupy these areas, which were once regarded as distant, environmental pollution problems began to occur due to occupation of the land without planning. Based on this occurrence, this study aims to propose environmental zoning for the Maxaranguape river watershed in order to protect its water resources. This is important because this river can serve as a source of supply for the metropolitan area of Natal, the capital of Rio Grande do Norte. In accordance to this proposition, the model of natural soil loss vulnerability (CREPANI et al., 2001), the model of aquifer pollution vulnerability (FOSTER et al., 2006), and the legal incompatibility map (CREPANI et al., 2001) were used to delimit the zones. All this was done with Geographic Information System (GIS) and also created a geographic database update of the basin. The results of the first model mentioned indicated that 63.67% of the basin was classified as moderately stable / vulnerable, 35.66% as moderately vulnerable, and 0.67% as vulnerable. The areas with high vulnerability degree correspond with sand dunes and river channels areas. The second model indicated that 2.84% of the basin has low vulnerability, 70.27%) has median vulnerability, and 26.76% and 0.13% has high vulnerability and extreme vulnerability, respectively. The areas with the highest vulnerability values also refer to part of the sand dunes and river channels besides other areas such as Pureza urban area. The legal incompatibility map indicated that the basin has 85.02 km2 of Permanent Protection Area (PPA) and 14.62% of this area has some incongruity of use. Based on these results it was possible to draw three main zones: Protection and Sustainable Use Zone (PSUZ), Protection and Environmental Restoration Zone (PERZ) and Environmental Control Zone, which are divided into A, B and C. The PSUZ refer to the coastal areas of the basin, where the sand dunes are located. These sites should be areas of environmental protection and of sustainable urban expansion. The ZPRA refer to river channels, which are in high need of rehabilitation. The third zone corresponds to the rest of the basin which should have, in general, the mapping of possible sources of contamination for further control on the use and occupation of the river

Método monoscópico para a determinação automática da altura de edifícios em fotografias aéreas

This paper proposes a monoscopic method for automatic determination of building's heights in digital photographs areas, based on radial displacement of points in the plan image and geometry at the time the photo is obtained. Determination of the buildings' heights can be used to model the surface in urban areas, urban planning and management, among others. The proposed methodology employs a set of steps to detect arranged radially from the system of photogrammetric coordinates, which characterizes the lateral edges of buildings present in the photo. In a first stage is performed the reduction of the searching area through detection of shadows projected by buildings, generating sub-images of the areas around each of the detected shadow. Then, for each sub-image, the edges are automatically extracted, and tests of consistency are applied for it in order to be characterized as segments of straight arranged radially. Next, with the lateral edges selected and the knowledge of the flight height, the buildings' heights can be calculated. The experimental results obtained with real images showed that the proposed approach is suitable to perform the automatic identification of the buildings height in digital images.

Extração semi-automática de rodovia baseada em um par estéreo de imagens aéreas e em otimização por programação dinâmica no espaço-objeto

This article proposes a method for 3D road extraction from a stereopair of aerial images. The dynamic programming (DP) algorithm is used to carry out the optimization process in the object-space, instead of usually doing it in the image-space such as the DP traditional methodologies. This means that road centerlines are directly traced in the object-space, implying that a mathematical relationship is necessary to connect road points in object and image-space. This allows the integration of radiometric information from images into the associate mathematical road model. As the approach depends on an initial approximation of each road, it is necessary a few seed points to coarsely describe the road. Usually, the proposed method allows good results to be obtained, but large anomalies along the road can disturb its performance. Therefore, the method can be used for practical application, although it is expected some kind of local manual edition of the extracted road centerline.
