Características sociodemográficas da mortalidade por câncer de boca em Bauru, SP, no período de 1991 a 2001: uso de geoprocessamento

O objetivo deste estudo foi avaliar as taxas de mortalidade por câncer de boca no período de 1991-2001, no município de Bauru-SP. A fonte de informação utilizada para o reconhecimento e seleção da população-alvo foram Certidões de Óbito dos Cartórios do município de Bauru com dados relativos ao período 1991-2001. Foram coletadas informações referentes a sexo, idade, localização da lesão e endereço. A coleta dos endereços visou à identificação no mapa do município de Bauru da localização geográfica do domicílio. Utilizando ferramentas do geoprocessamento, foi feita a inserção no mapa dos casos identificados. Foram registrados 67 casos de morte por câncer de boca na cidade de Bauru entre 1991 e 2001, com maiores taxas no sexo masculino e sexta década de vida. A análise da distribuição espacial mostra que a maioria dos casos encontra-se próxima à linha férrea que corta o município e foi responsável, em grande parte, pela ocupação territorial pela população, sendo esta também uma área que abrange os bairros mais antigos do município. O câncer de boca constitui importante causa de óbito no município, requerendo um planejamento de ações georreferenciadas pelo sistema local de saúde.

Evaluation of Antihyperglycemia and Antihypertension Potential of Native Peruvian Fruits Using In Vitro Models

Local food diversity and traditional crops are essential for cost-effective management of the global epidemic of type 2 diabetes and associated complications of hypertension. Water and 12% ethanol extracts of native Peruvian fruits such as Lucuma (Pouteria lucuma), Pacae (Inga feuille), Papayita arequipena (Carica pubescens), Capuli (Prunus capuli), Aguaymanto (Physalis peruviana), and Algarrobo (Prosopis pallida) were evaluated for total phenolics, antioxidant activity based on 2, 2-diphenyl-1-picrylhydrazyl radical scavenging assay, and functionality such as in vitro inhibition of alpha-amylase, alpha-glucosidase, and angiotensin I-converting enzyme (ACE) relevant for potential management of hyperglycemia and hypertension linked to type 2 diabetes. The total phenolic content ranged from 3.2 (Aguaymanto) to 11.4 (Lucuma fruit) mg/g of sample dry weight. A significant positive correlation was found between total phenolic content and antioxidant activity for the ethanolic extracts. No phenolic compound was detected in Lucuma (fruit and powder) and Pacae. Aqueous extracts from Lucuma and Algarrobo had the highest alpha-glucosidase inhibitory activities. Papayita arequipena and Algarrobo had significant ACE inhibitory activities reflecting antihypertensive potential. These in vitro results point to the excellent potential of Peruvian fruits for food-based strategies for complementing effective antidiabetes and antihypertension solutions based on further animal and clinical studies.

Biomarkers of selenium status in the amazonian context: Blood, urine and sequential hair segments

Selenium (Se) is an essential element and deficit or excess of dietary Se is associated with health disorders. Relatively elevated Se levels have been reported in the Brazilian Amazon, where there are also important annual variations in the availability of different foods. The present study was conducted among six riparian communities of the Tapajos River to evaluate seasonal variations in blood and sequential hair cm Se concentrations, and to examine the relationships between Se in blood and hair, and blood and urine. Two cross-sectional studies were conducted, at the descending water (DWS, n = 259) and the rising water (RWS, n = 137) seasons, with repeated measures for a subgroup (n = 112). Blood Se (B-Se), hair Se (H-Se) and urine Se (U-Se) were determined. Match-paired analyses were used for seasonal comparisons and the method of best fit was used to describe the relationships between biomarkers. B-Se levels presented a very large range (142-2447 mu g/l) with no overall seasonal variation (median 284 and 292 mu g/l, respectively). Sequential analysis of 13 cm hair strands showed significant variations over time: Se concentrations at the DWS were significantly lower compared with the rising water season (medians: 0.7 and 0.9 mu g/g; ranges: 0.2-4.3 mu g/g and 0.2-5.4 mu g/g, respectively). At both seasons, the relationships between B-Se and H-Se were linear and highly significant (r(2) = 67.9 and 63.6, respectively), while the relationship between B-Se and U-Se was best described by a sigmoid curve. Gender, age, education and smoking did not influence Se status or biomarker relationships. Variations in H-Se suggest that there may be seasonal availability of Se sources in local food. For populations presenting a large range and/or elevated Se exposure, sequential analyses of H-Se may provide a good reflection of variations in Se status.

Immunohistochemical study of Langerhans cells in cutaneous lesions of the Jorge Lobo`s disease

Jorge Lobo`s disease is a chronic infection caused by the fungus Lacazia loboi endemic in South America. The infection is characterized by the appearance of parakeloidal, ulcerated or verrucous nodular or plaque-like cutaneous lesions. The histopathological aspect is characterized by poorly organized granulomas with histiocytes and multinucleated giant cells. Little is known about local immune response in lobomycosis skin lesions. Thirty-three skin biopsies from patients with Jorge Lobo`s disease were selected from Ambulatory of Dermatology, UFPA. The control group was constituted by ten biopsies from normal skin. Langerhans cells were identified by immunohistochemistry using anti-CD1a antibody (Serotec). The number of positive cells was statistically analyzed. Langerhans cells were visualized along the epidermis in biopsies from Jorge Lobo`s disease and the morphology and the number of Langerhans cells did not differ from normal skin (p > 0.05). In Jorge Lobo`s disease, this cell population probably presents some escape mechanism of the local immune system to evade the antigen presentation by those cells. (C) 2010 Published by Elsevier B.V.

Industrial districts, innovation and I-district

The I-district effect hypothesis establishes the existence of highly intense innovation in Marshallian industrial districts due to the presence of external localization economies. However, industrial districts are characterized by specific manufacturing specializations in such a way that this effect could be due to these dominant specializations. The objective of this research is to test whether the effect is explained by the conditions of the territory or by the industrial specialization and to provide additional evidence of the existence and causes of the highly intense innovation in industrial districts (I-district effect). The estimates for Spain of a fixed effects model interacting territory and industry suggest that the high innovative performance of industrial districts is maintained across sectors whereas the industrial specialization behaves differently depending on the type of local production system in which it is placed. The I-district effect is related to the conditions of the territory more than to the industrial specialization. The territory is a key variable in explaining the processes of innovation and should be considered a basic dimension in the design of innovation and industrial policies.

Adaptations des recommandations pour la pratique clinique: l'exemple du Programme cantonal Diabète de Vaud [Adaptation of clinical practice guidelines--the example of cantonal Diabetes Program].

With the growing number of scientific publications, practitioners can use scientific knowledge synthesis, including Clinical Practice Guidelines (CPG). The practical use of a CPG implies considering the context, that is the local healthcare system and the patient. Thus, the CPG can never replace the expertise of the practitioner! Diabetes is a wide public health issue and the canton of Vaud established the cantonal Diabetes Program (cDP), to optimize the care of diabetic patients. The cDP has many projects including the adaptation of reliable CPG to local needs. We present the pros and cons of the CPG in the cDP and the methods to adapt it to the regional healthcare context, and also at an individual level.

Determinación de sistemas de flujo regionales y locales en las depresiones tectónicas del Baix Empordà y La Selva (NE de España) en base a datos hidroquímicos e isotópicos

The Baix Empordà-Selva-Gavarres aquifer system is related to the fault set that created the tectonic basins of Empordà and Selva areas (NE Spain) during the Neogene. In this work, we describe groundwater hydrogeological, hydrochemical and isotopical (3H, δD, δ18O, and the 87Sr/86Sr ratio) characteristics of this system in order to illustrate the relevance of fault zones in groundwater flow-paths and the recharge. In that way, we identify two flow systems, with distinct hydrochemistry and isotopes. A local flow system originates at the Gavarres Range, and it flows towards the basins of the Baix Empordà and Selva, with an approximate residence time of 20 years. Additionally, a regional flow system has only been identified in the Selva basin. This one is related to the main fault zones, as preferential flow paths. Its recharge is located in mountain ranges with higher altitudes, namely the Transversal and Guilleries Ranges, with residence times larger than 50 years. Isotopical data has also shown mixing processes between both flow systems and rainfall recharge while multivariate statistical analysis of principal components has shown the main processes that control hydrochemistry of each flow systems

Iowa Highway Research Board TR-423: 1949–1999, 1999

The year 1949 saw the Iowa General Assembly’s establishment of the Iowa Secondary Road Research Fund, which led to the creation of a supervisory board within what was then the Iowa State Highway Commission to oversee the expenditure of that fund. The purpose of the fund and the board was to research road construction topics likely to be beneficial to the working of Iowa’s secondary, or local, road system. The supervisory board—called the Iowa Highway Research Board (the “Board”)—was organized by the highway commission in December 1949 and first met in May 1950. The creation of the fund and of the Iowa Highway Research Board marked the first organized effort in the United States to investigate local road construction problems and placed Iowa in the forefront of this field of engineering research. That Iowa should be a leader in such an effort is not surprising, given the early and sustained emphasis of the Iowa State Highway Commission on both research and the dissemination of information to county authorities. Now, 50 years later, a retrospective is in order. To that end, the Iowa Highway Research Board commissioned the preparation of a commemorative history. This work is the result of that project. Throughout its existence, the Board has funded nearly 450 projects, several of national significance. Many new construction and maintenance techniques have been developed, some of which have evolved into standard practices in highway construction. Innovative new materials and equipment have been tested. Still other projects have considered a wide variety of subjects related to the efficient operation of the highway system. Highway safety, conservation, and law have all come under research scrutiny. While it will not be possible, given the short space available, to consider all the projects financed by the Iowa Highway Research Board, it is well worthwhile to examine the Board’s principal projects and its resulting contributions to the field of highway research.

Browse through this guide and you’ll find the distinct flavor of what is available along each byway. Discover recreational, historic, cultural and scenic attractions using the maps and lists provided in the guide. You’ll find numbered attractions for each byway in or near the town listed. For a comprehensive list of byway features, visit www.iowabyways.org. Friendly local contacts are provided to help you along the way. Iowa Transportation Maps clearly tracking all the Iowa byways with red dotted lines are available at Iowa’s official welcome centers. Traveling Iowa’s byways you will experience small town America, while enjoying diverse landscapes and unique landforms that have been shaped over thousands of years. Iowa’s cultural heritage also plays a major role across all 11 byways, boasting hundreds of historic sites, national landmarks and interpretive centers, each telling Iowa’s stories from the first Native Americans through European immigrants to modern times. Glaciers once covered much of Iowa, shaping the broad flat plains of the prairie. These massive sheets of ice missed the northeast corner of the state, leaving the land along the Driftless Area Byway rugged and hilly with rock outcroppings, springs and cold water trout streams. Rivers coursed their way through the land, carving deep furrows in some places and leaving gently rolling hills in others. In western Iowa, wind has shaped fine sand into the impressive Loess Hills, a rare land form found in only one other place on earth. Iowa’s two national scenic byways and nine state byways offer unique varieties of scenic features, and more for you to see and do. View three states from atop a Mississippi River bluff, stop at a modern art museum and then tour a working farm. Explore a historic mill, visit a national aquarium, take a boat ride in a cave, purchase locally crafted pottery and wares from local artisans or trace the footsteps of Lewis and Clark. Experience the actual wagon ruts of the Mormon Trail, ride your bike 13 stories high, canoe a water trail, star gaze under Iowa’s darkest sky, and marvel at mounds built by prehistoric cultures. Agriculture wraps Iowa’s byways with an abundance of farmland vistas and fills Iowa lands with ever-changing crops and activities for you to “harvest.” You’ll see croplands on the vast flat plains and farmsteads sprinkled across rolling hills reminiscent of a Grant Wood painting. Along the way, you might wander in a corn maze, rest at a bed and breakfast, study farming in museums, discover the Iowa barn quilt collection or visit a working Amish farm. When you are ready to step outside your vehicle, you’ll find much more to do and see. Prairie, forests, rivers and public lands are abundant along Iowa’s byways; providing opportunities for you to stop and play in the outdoors with hiking, biking, kayaking and trout fishing. Classic hometowns with pride for their unique lore and offerings are found all along the byways. They invite you to taste local food, enjoy their architecture, and immerse yourself in the rich history and culture that defines them. Why not plan your next journey off the beaten path? No matter how you choose to make the most of every moment, we know that time spent along Iowa’s byways is sure to grow your love for Iowa’s diverse, beautiful vistas and authentic communities. Happy driving!

Surface Improvement and Dust Palliation of Unpaved Secondary Roads and Streets, HR-151, 1973

As of December 31, 1970 there were 57,270 miles of Local Secondary roads and 32,958 miles of Farm to Market roads in the Iowa secondary road system. The Local Secondary system carried a traffic load of 2,714,180 daily vehicle miles, accounting for 32% of all traffic in the secondary system. For all Local Secondary roads having some form of surfacing, 98% were surfaced with gravel or crushed stone. During the 1970 construction year 335 miles of surfaced roads were constructed in the Local Secondary system with 78% being surfaced with gravel or crushed stone. The total maintenance expenditure for all secondary roads in Iowa during 1970 amounted to $40,086,091. Of this, 42%, or $17,020,332, was spent for aggregate replacement on existing gravel or crushed stone roads with an additional 31% ($12,604,456) being spent on maintenance other than resurfacing. This amounts to 73% of the total maintenance budget and are the largest two maintenance expenditure items out of a list of 10 ranging from bridges to drainage assessments. The next largest item was 7%, for maintenance of existing flexible bases. Three concurrent phases of study were included in this project: (1) laboratory screenings studies of various additives thought to have potential for long-lasting dust palliation, soil additive strength, durability, and additive retention potential; (2) test road construction using those additives that indicated promise for performance-serviceability usage; and (3) observations and tests of constructed sections for evaluation of the additive's contribution to performance and serviceability as well as the relationship to initial costs.

The role of the δ-opioid receptor in skin homeostasis and wound healing

Au regard des agressions environnementales constantes que la peau doit endurer, l'équilibre fragile entre l'expression et la répression des gènes épidermiques, nécessaire à la différentiation et la prolifération des kératinocytes, pourrait facilement être perturbé en l'absence des mécanismes de stabilisation robustes. La présence d'un système neuroendocrinien local est donc importante afin de coordonner une réponse aux éventuelles irritations. En effet, l'expression de plusieurs neurohormones, des neurotransmetteurs et des neuropeptides, y compris des dérivés pro-opiomélanocortine comme la ß-endorphine et [Met5]-enképhaline, ainsi que l'expression du récepteur 8-opioïde (DOR) a été démontré dans la peau. Cependant, les mécanismes moléculaires par lesquels ils modulent la fonction des kératinocytes sont mal connus. Le présent travail démontre que la voie de signalisation DOR active spécifiquement la voie ERK 1/2 MAPK dans les lignées cellulaires de kératinocytes humains, inhibant la prolifération des cellules et entraîne une diminution de l'épaisseur épidermique dans un modèle organotypique de peau. De plus, l'expression de DOR retarde nettement l'induction de la kératine 10 (KRT 10) et la kératine 1 (KRT 1) dans une modèle 2D de différentiation in vitro, et supprime l'induction de KRT 10 dans un modèle organotypique de peau. Ceci est accompagné de la dérégulation de l'involucrine (IVL), la loricrine (LOR) et la fïlaggrin (FLG), résultant en une induction nettement réduite de leur expression lors de l'initiation de la différentiation in vitro. De plus, POU2F3 a été identifié comme un facteur de transcription régulant les gènes de différentiation des kératinocytes modulés par DOR. Il a été démontré que la régulation négative de POU2F3 via la voie DOR-ERK affecte les principaux aspects de la fonction des kératinocytes. Toutefois, il est évident que des facteurs supplémentaires influencent la fonctionnalité de la voie DOR elle-même. Le calcium et le contact cellule-cellule augmentent la quantité des récepteurs à la surface cellulaire des kératinocytes. Les kératinocytes dont les récepteurs sont internalisés ne répondent pas de la même manière que ceux possédant des récepteurs fonctionnels localisée à la membrane. Ce travail suggère que lors de signaux intrinsèques ou extrinsèques spécifiques, les kératinocytes sont capable de répondre via le système opioïdergique neuro-epidermique. Cette réponse doit être spatialement et temporairement contrôlée afin d'éviter un déséquilibre de l'homéostasie épidermique et un retard de cicatrisation. La compréhension de ce processus très complexe pourrait permettre à terme le développement de meilleurs traitements des affections cutanées pathologiques. En complément des études précédentes sur des souris DOR-défïcientes, ces données suggèrent que l'activation de DOR dans les kératinocytes humains influence la morphogenèse et l'homéostasie de l'épiderme, et pourrait jouer un rôle lors du processus de cicatrisation. - In view of the constant environmental assaults that the skin must endure, the delicate balance of an eloquent sequence of epidermal gene expression and repression, that is required for appropriate differentiation and proliferation of keratinocytes, might easily become derailed in the absence of robust stabilizing mechanisms. The presence of a local neuroendocrine system is thereby important to coordinate a response towards irritations. In fact, the expression of several neurohormones, neurotransmitters, and neuropeptides, including proopiomelanocortin derivatives, such as ß- endorphin and [Met5]-enkephalin has been shown in skin, as well as expression of the 6-opioid receptor (DOR). However, there is currently a lack of understanding of the molecular mechanisms by which their signalling modulates keratinocyte function. The present work demonstrates that DOR signalling specifically activates the ERK 1/2 MAPK pathway in human keratinocyte cell lines. This activation inhibits cell proliferation, resulting in decreased epidermal thickness in an organotypic skin model. Furthermore, DOR expression markedly delays induction of keratin intermediate filament Keratin 10 (KRT 10) and KRT 1 during in vitro differentiation, and abolishes the induction of KRT 10 in the organotypic skin model. This is accompanied by deregulation of involucrin (IVL), loricrin (LOR), and filaggrin (FLG), illustrated by a markedly reduced induction of their expression upon initiation of differentiation in vitro. Additionally, POU2F3 was identified as a transcription factor mediating the DOR induced regulation of keratinocyte differentiation related genes. It was revealed that DOR-mediated ERK-dependent downregulation of this factor affects key aspects of keratinocyte function. However, it is evident that additional triggers influence the functionality of the DOR itself. Calcium at concentrations above 0.1 mM and cell-cell contact both enhance the presence of receptor molecules on the keratinocytes cell surface. Keratinocytes with internalized receptor do not respond to DOR ligands in the same way as keratinocytes with a functional membrane localized receptor.
