    2009-04-01

    The University of Turin, in cooperation with the Egyptian Antiquity Museum, has recently undertaken several projects aimed at developing a scientific approach to the analysis of ancient Egyptian finds. In particular, a straightforward project to investigate the stony handcrafts preserved in the statuary rooms started in 2006 to obtain their systematic petrographic classification and their possible geological sources. The main intent of the project was to understand the provenance of the materials used in Pharaonic period, setting the base for the identification of the ancient quarry sites and for a correct interpretation of the extraction and working techniques, in order to provide fundamental information about economical and social development of Egyptian civilization through historical times. The choice to focus attention on black and red granites came from the statement of the percentage relevance (40 of the 54 sculptures actually exposed) of these materials in the statuary rooms. Moreover, especially for black granites, the need of detailed minero-petrographic analysis arose from the difficulty in making a macroscopic classification of the fine-grained dark-coloured rock varieties. Therefore, five black granite statues, belonging to the Drovetti collection were sampled in a micro-invasive way: three sculptures of goddess Sekhmet (cat. 260, 251, 247), the statue of Ramses II (cat. 1380) and the statue of goddess Hathor (cat. 694). The choice to analyse even three of the twenty-one statues of goddess Sekhmet (cat. 247, cat. 251, cat. 260), originally located in the same Egyptian temple but ichnographically different, derived from the need of answering the archaeological questions about their provenance. On the other hand, the opportunity of studying the fine-grained black rocks used for the sculptures of goddess Hathor (cat. 694) and of Ramses II in Majesty (cat. 1380), symbol of the Egyptian museum of Turin, provided the opportunity to analyse and classify the

    The combination of X-Ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive Spectrometry (SEM-EDS), Differential Thermal Analysis-Thermogravimetry (DTA-TG) and Optical Microscopy (OM) has been used to study several different ancient mortars recovered in the S. Nicola Church (built after the devasting earthquake of the 1693) and other historic buildings located in the historical center of Catania (Eastern Sicily). Investigations have been focused on the identification of raw materials mixed in the different mortars and their provenance as well as on the study of the relevant technological aspects of manufacturing processes. Minero-petrographic data have often shown that local volcanic raw materials have been used as aggregate fractions and, in particular, a new volcanic material, the so-called ghiara, has been largely adopted for the construction of the walls of the monuments after the earthquake. It is worthy to note that ghiara is a by-product of erupted magma during the impressive Etna eruption of 1669, which almost completely covered the centre of Catania. The following reaction with the soil gave rise to the formation of a layer of this typical ochre-coloured material. Moreover, the precise provenance of the ghiara has been determined trough geological surveys of the most important historic quarries. Results have allowed the identification of exploited sources of ghiara. Furthermore, combination of SEM-EDS results and thermal information have indicated the hydraulic nature of the mortars due to the formation of hydraulic phases at the binder-aggregate interface. It, therefore, is due to the fact that the ghiara has slight pozzolanic properties. Present data have an important role for any satisfactory reproduction of the ancient manufacturing techniques to be used for the restoration of the S. Nicola Church.

    In Peru, the industry's development has made economic improvements but at the same time, it has had a major impact on the health of the workers; for that reason, it was necessary to generate control mechanisms. So, in 1940 it was created the Departmento de Higiene Industrial, which in 1956 was changed to Instituto de Salud Ocupacional, but it was deactivated in 1994. However, in 2001 it reappeared into the Ministerio de Salud organizational structure with the name of Instituto de Salud Ocupacional "Alberto Hurtado Abadía". Actually, it is the Centro Nacional de Salud Ocupacional y Protección del Ambiente para la Salud (CENSOPAS), organ of the Instituto Nacional de Salud which continues working in synergy with other institutions and sectors, making research to protect the health of exposed persons (workers and community) to contamination and risks associated with economic activities.

    Higher-quality Touriga Nacional (TN) wines are characterized by a fruity-citric aroma described as sweet and fresh citrus evoking the bergamot fruit (Citrus bergamia). In fact, "bergamot-like" descriptor is currently employed to rate higher quality TN wines. The aim of this work was to identify among volatile compounds present in bergamot fruit extracts (mainly terpenes) which of them contributes the most to the bergamot overall perception, and relate these data with the volatile composition of TN wines. The identification of the most important descriptors was done by sensory analysis. Among 18 descriptors 3 were selected: bergamot-like aroma, orange like, and violet. A GCO of a typical TN wine extract allows the identification of 3 related odorant zones ZO1, ZO2, and ZO3 related with bergamot-like aroma. Using AEDA, ZO2 was confirmed to be one of the most important odorant zones. Using AEDA the presence of linalool and linalyl acetate was confirmed. A similarity test was performed with a non-TN wine added with linalool and linalyl acetate alone or in combinations. The highest similarity value was observed when linalool (SV = 5.9) was added. In fact, results obtained from the analysis of several red wines from different varieties show that terpenols are present in higher amounts in wines coming from TN variety, which proves that these compounds can be the clue to the varietal aroma of TN wines.

    The orchid-bee faunas of 'Parque Nacional do Monte Pascoal', 'Parque Nacional do Descobrimento' and three other Atlantic Forest remnants ranging from 1 to 300 ha in southern Bahia, eastern Brazil, were surveyed. Baits with seventeen different scents were used to attract orchid-bee males. Four thousand seven hundred and sixty-four males belonging to 36 species were actively collected with insect nets during 300 hours from November, 2008 to November, 2009. Richness and diversity of orchid bees found in this study are the highest ever recorded in the Atlantic Forest domain. Eufriesea dentilabris (Mocsáry, 1897) and Eufriesea violacea (Blanchard, 1840) were collected at the 'Parque Nacional do Monte Pascoal', the first record of these species for the state of Bahia and the northernmost record for both species. Females Exaerete dentata (Linnaeus, 1758) were also collected at 'Parque Nacional do Monte Pascoal' and old records of Eufriesea aeneiventris (Mocsáry, 1896) in this area makes this site the richest and most diverse concerning its orchid-bee fauna in the entire Atlantic Forest and similar to areas in the Amazon Basin.

    Ecuador's economic history has been closely linked to Theobroma cacao L cultivation, and specifically to the native fine flavour Nacional cocoa variety. The original Nacional cocoa trees are presently in danger of extinction due to foreign germplasm introductions. In a previous work, a few non-introgressed Nacional types were identified as potential founders of the modern Ecuadorian cocoa population, but so far their origin could not be formally identified. In order to determine the putative centre of origin of Nacional and trace its domestication history, we used 80 simple sequence repeat (SSR) markers to analyse the relationships between these potential Nacional founders and 169 wild and cultivated cocoa accessions from South and Central America. The highest genetic similarity was observed between the Nacional pool and some wild genotypes from the southern Amazonian region of Ecuador, sampled along the Yacuambi, Nangaritza and Zamora rivers in Zamora Chinchipe province. This result was confirmed by a parentage analysis. Based on our results and on data about pre-Columbian civilization and Spanish colonization history of Ecuador, we determined, for the first time, the possible centre of origin and migration events of the Nacional variety from the Amazonian area until its arrival in the coastal provinces. As large unexplored forest areas still exist in the southern part of the Ecuadorian Amazonian region, our findings could provide clues as to where precious new genetic resources could be collected, and subsequently used to improve the flavour and disease resistance of modern Ecuadorian cocoa varieties.

    GNSS navigation satellites are currently being developed by all major players in the science and technology scene, to compete with the GPS system. Because their applications span many different areas, from traffic and cargo control, to geodesy and seismic monitoring, it is required to assess the coherence between the different constellations. BDS is the GNSS system currently developed in China. Its first generation of satellites consisted of 3 geostationnary satellites allowing geolocalisation in China only. In addition to these satellites, other satellites have been launched in geostationnary and geosynchronous orbits, as well as satellites orbiting with a classical GNSS semi-major axis. With these additions, the BDS system possesses 19 operating satellites, and though the system is mostly efficient for geolocalisation in Asia, the satellites are also visible in other parts of the globe. In parallel to the development of the BDS constellation, China has launched the iGMAS (International GNSS Monitoring and Assessment Service) project to develop a global tracking network of multi-GNSS geodetic receivers. One of the goals of this project is to evaluate the efficiency of the BDS constellation as well as the efficiency of the receivers developed by the Chinese laboratories. As part of the Brazilian program COSBAN leaded by the Foreign Affairs Ministry to foster up the science and technology partnership with China, materialized by the collaboration between the Shanghai Astronomical Observatory/CAS and the Observatório Nacional/MCTI, in Rio de Janeiro. Through it the RIOS-iGMAS station was installed at Observatório Nacional, where the RJEP GNSS station already operates as part of the Brazilian reference system. Thus at the Observatório Nacional can be observed satellites from any constellation with both systems of reception, leading to a direct, efficient way to compare the results obtained for each network.

    In 1998, stem cell research became a subject of heightened controversy. In Brazil, the polemic came to a head in 2008 when the Federal Supreme Court commenced a judicial review of the new Biosecurity Law because it permitted the use of human embryos in research. This study analyzes the coverage of human embryonic stem cell research on the national daily evening news show, Jornal Nacional . A positive tone is observed, marked by a focus on the potential benefits of the research and omission of its limitations and risks. The limited success rate thus far obtained from embryonic stem cell research and the risks of inducing the formation of tumors were omitted, intimating that the only barrier to new treatments and cures was the legislation.

    We present the results of speckle interferometric measurements of binary stars performed in November, 2008 with the 1 m telescope at the Observatorio Astronómico Nacional of Tonanzintla (Puebla, Mexico). The data include 175 position angle and separations measured for 163 systems. The measured angular separations range from 0.15" to 4.00". The maximum magnitude of the brighter components is equal to 9.32. The mean error in the separation measurement is 0.03" and in the position angle is 1°. The majority of position angles were determined with the usual 180° ambiguity, and some of them were corrected by comparison with observations performed by other observers.

    During the past 10 years, the Instituto Nacional de Salud Pública (National Institute of Public Health) in Mexico has meticulously revised its educational model. This analysis resulted in the transformation of its educational model by tracing a new path in the pedagogical structure and faculty development to meet current challenges and students’ needs. The first stage dealt with the national and international accreditation standards that came with the 21st century. The second stage responded to evidence of cognitive research showing that students are better prepared when they are engaged, active, and responsible for their own learning. This transformation was grounded on the use of information and communication technologies and on a competency-based educational approach that has led the expansion and innovation of educational practice.

    Ambient dose equivalent values were determined in several sites at the Instituto Nacional de Cancerologia, Departmento de Medicina Nuclear, using TLD-100 and TLD-900 thermoluminescent dosemeters. Additionally, ambient dose equivalent was measured at a corridor outside the hospitalization room for patients treated with {sup 137}Cs brachytherapy. Dosemeter calibration was performed at the Instituto Nacional de Investigaciones Nucleares, Laboratorio de Metrologia, to known {sup 137}Cs gamma radiation air kerma. Radionuclides considered for this study are {sup 131}I, {sup 18}F, {sup 67}Ga, {sup 99m}Tc, {sup 111}In, {sup 201}Tl and {sup 137}Cs, with main gamma energies between 93 and 662 keV. Dosemeters were placed during a five month period in the nuclear medicine rooms (containing gamma-cameras), injection corridor, patient waiting areas, PET/CT study room, hot lab, waste storage room and corridors next to the hospitalization rooms for patients treated with {sup 131}I and {sup 137}Cs. High dose values were found at the waste storage room, outside corridor of {sup 137}Cs brachytherapy patients and PET/CT area. Ambient dose equivalent rate obtained for the {sup 137}Cs brachytherapy corridor is equal to (18.51{+-}0.02)x10{sup -3} mSv/h. Sites with minimum doses are the gamma camera rooms, having ambient dose equivalent rates equal to (0.05{+-}0.03)x10{sup -3} mSv/h. Recommendations have been given to the Department authorities so that further actions are taken to reduce doses at high dose sites in order to comply with the ALARA principle (as low as reasonably achievable).

    In 1988, the Instituto Geofisico (IG) began a permanent surveillance of Ecuadorian volcanoes, and due to activity on Guagua Pichincha, SP seismic stations and EDM control lines were then installed. Later, with the UNDRO and OAS projects, telemetered seismic monitoring was expanded to Tungurahua, Cotopaxi, Cuicocha, Chimborazo, Antisana, Cayambe, Cerro Negro, and Quilotoa volcanoes. In 1992 an agreement with the Instituto Ecuatoriano de Electrificacion strengthened the monitoring of Tungurahua and Cotopaxi volcanoes with real-time SP seismic networks and EDM lines. Thus, background activity levels became established, which was helpful because of the onset of the 1999 eruptive activity at Tungurahua and Guagua Pichincha. These eruptions had a notable impact on Baños and Quito. Unrest at Cotopaxi volcano was detected in 2001-2002, but waned. In 2002 Reventador began its eruptive period which continues to the present and is closely monitored by the IG. In 2006 permanent seismic BB stations and infrasound sensors were installed at Tungurahua and Cotopaxi under a cooperative program supported by JICA, which allowed us to follow Tungurahua's climatic eruptions of 2006 and subsequent eruptions up to the present. Programs supported by the Ecuadorian Secretaria Nacional de Ciencia y Tecnologia and the Secretaria Nacional de Planificacion resulted in further expansion of the IG's monitoring infrastructure. Thermal and video imagery, SO2 emission monitoring, geochemical analyses, continuous GPS and tiltmeters, and micro-barometric surveillance have been incorporated. Sangay, Soche, Ninahuilca, Pululahua, and Fernandina, Cerro Azul, Sierra Negra, and Alcedo in the Galapagos Islands are now monitored in real-time. During this time, international cooperation with universities (Blaise Pascal & Nice-France, U. North Carolina, New Mexico Tech, Uppsala-Sweden, Nagoya, etc.), and research centers (USGS & UNAVCO-USA, IRD-France, NIED-Japan, SGC-Colombia, VAAC, MIROVA) has introduced

    The aim of this study was to evaluate non-Saccharomyces yeasts isolated from spontaneous fermenting musts of Touriga Nacional (TN), one of the most important Portuguese red grape variety, to improve and diversify TN wines. Two hundred and seventy nine isolates were assigned to 11 yeast species by conventional molecular and growth tests. Starmerella bacillaris was the most frequently detected yeast species, followed by Hanseniaspora guilliermondii and Hanseniaspora uvarum. Twenty-three isolates from 10 species were selected for oenological study, namely fermentation performance, physicochemical and quantitative descriptive sensory analysis of the wines produced. A significant species effect was observed for most of the variables evaluated, some species generating wines with quite interesting aromas. Candida diversa and S. bacillaris isolates produced wines with higher overall quality, higher balance and more intense and diverse aroma. Furthermore, S. bacillaris isolates generated wines with enhanced TN typical aroma, such as bergamot, violet and rock-rose, and were thus regarded as the most promising for improving TN wines. This study revealed the diversity of wine aroma profiles generated by non-Saccharomyces yeast isolates. This knowledge is particularly important given the growing trend from industry to use non-Saccharomyces yeasts as a tool for improving and diversifying the sensory characteristics of wine. © 2014 The Society for Applied Microbiology.

    The Centro Nacional de Aceleradores (CNA) hosts a 1 MV accelerator mass spectrometry (AMS) apparatus since September 2005. In order to improve its overall performance, several updates have been made on the existing facility during the last 10 years of operation. In this paper, two modifications conducted in 2015 will be described. To increase the transmission of the ions through the accelerator, the stripping gas on the 1 MV CNA machine was changed from Ar to He. The measured maximum transmission for almost every isotope results to be higher, especially for heavy masses: for instance, in the case of uranium in the 3+ charge state, the transmission increased from 11% with Ar gas to about 38% with He gas. The second advance consisted of the substitution of the existing gas ionization chamber with a new one provided by ETH Zurich. The ETH detector features with its miniaturized design and is optimized for low energy AMS (i.e. very low electronic noise and efficient charge collection). As the electronic noise is the most important contribution to the resolution for light ions, the total energy resolution has been reduced by 15% in the case of 10Be, allowing a better discrimination against its isobar, 10B. For the heaviest radionuclides where the quality of the spectra is determined by the charge carrier production in the gas, the resolution for 2.7 MeV uranium ions was improved by 30%, probably due to a more efficient charge collection.

    Since February 2006, the new 1 MV multielement compact AMS facility SARA (Spanish Accelerator for Radionuclides Analyses) at the Centro Nacional de Aceleradores (CNA) in Sevilla (Spain) is fully operative. During the first one and a half year of operation, the viability of the system for the measurement of 10Be, 14C, 129I and plutonium isotopes, 239Pu and 240Pu, has been evaluated. First results have demonstrated that, in terms of precision and detection limits, the performance of the device compares to other compact AMS facilities, although some progress can still be done in order to optimize its capacities. At this moment, background levels are in the order of 10-14 for 10Be/9Be, 10-13 for 129I/127I, 10-15 for 14C/12C (processed and unprocessed blank) and about 106 atoms for plutonium isotopes: 239Pu, 240Pu and 242Pu. In this work, the current status of the AMS measurements at CNA for the above mentioned radionuclides is described.

    Plutonium isotopes have been recently added to the list of radionuclides that can be measured with the new generation of compact AMS facilities. In this paper we present first experimental results concerning the development of the plutonium AMS technique at 680 kV on the 1 MV AMS system at the Centro Nacional de Aceleradores (CNA) in Sevilla, Spain. This is the first compact AMS machine designed and manufactured by High Voltage Engineering Europa. As we demonstrate, the obtained backgrounds for 239,240Pu, of about 10 6 atoms, and the 239Pu/ 238U mass suppression factor, in the range of 10 -9, compare to the ones achieved on other AMS facilities. With the measurement of reference materials provided by the International Atomic Energy Agency (IAEA-375, IAEA-Soil-6, IAEA-381) and samples already studied on the 600 kV compact ETH/PSI AMS system at Zürich, we show that the CNA system can be perfectly used for the routine measurement of plutonium isotopes at environmental levels.

    In February 1998, almost 10 years ago, the set-up of the first IBA (ion beam analysis) facility in Spain took place with the arrival of a 3 MV tandem accelerator [J. García-López, F.J. Ager, M. Barbadillo-Rank, F.J. Madrigal, M.A. Ontalba, M.A. Respaldiza, M.D. Ynsa, Nucl. Instr. and Meth. B 161-163 (2000) 1137]. Since then, an intensive research program using IBA techniques has been carried out. Subsequently, a cyclotron for 18 MeV protons has been also installed at the "Centro Nacional de Aceleradores" (CNA), devoted mainly to isotope production for PET (positron emission tomography) techniques, but possibly applied to material analysis and damage studies on a dedicated beam line. Moreover, a 1 MV tandem has been recently installed for AMS (accelerator mass spectrometry) 14C dating and environmental research with other isotopes. In the present paper we describe the new facilities and the developments of the 3 MV tandem beam lines occurred during the past years, as well as some examples of the most recent research activities in our Center in the fields of Material Science, Archaeometry, Biomedicine and Environment.

    We report first-year survival rates of 49 captive-reared Hispaniolan Parrots (Amazona ventralis) released in Parque Nacional del Este, Dominican Republic. Our goal was to learn about factors affecting postrelease survival. Specifically, we tested if survival was related to movements and whether modifying prerelease protocols influenced survival rates. We also estimated survival in the aftermath of Hurricane Georges (22 September 1998). Twenty-four parrots, fitted with radio-transmitters, were released between 14 September and 12 December 1997. Twenty-five more were released between 29 June and 16 September 1998. First-year survival rates were 30% in 1997 and 29% in 1998. Survival probability was related to bird mobility. In contrast to birds released in 1997, none of the 25 parrots released in 1998 suffered early postrelease mortality (i.e., 3-5 days after release). Two adjustments to prerelease protocols (increased exercise and reduced blood sampling) made in 1998 may have contributed to differences in mobility and survival between years. The reduction of early postrelease mortality in 1998 was encouraging, as was the prospect for higher first-year survival (e.g., 30% to 65%). Only one death was attributed to the immediate impact of the hurricane. Loss of foraging resources was likely a major contributor to ensuing mortality. Birds increased their mobility, presumably in search of food. Survival rates dropped 23% in only eight weeks posthurricane. This study underscores the value of standardized prerelease protocols, and of estimating survival and testing for factors that might influence it. Inferences from such tests will provide the best basis to make adjustments to a release program.

    The Observatório Nacional at Rio de Janeiro has developed a new heliometer to perform accurate measurements of the solar diameter. The equipment makes use of split parabolic mirrors, rather than split achromatic lenses as objective. In its first campaign this reflector heliometer generated a few thousands of images of the Sun through which we evaluate the precision of the solar diameter measurements as been 5 mas. The mechanical and thermal stability of the instrument is guaranteed by the use of a telescope tube manufactured in carbon fiber. The tube firmly holds the heliometric mirrors and the CCD camera that collects the images. The perfect lodging between the two half-mirrors over its supporting plate defines the angular instrumental separation between the two images of the sun. The heliometric mirrors and supporting plate have been made in ceramic material in order to ensure the stability of the optical configuration and to maintain the two images of the solar disk displaced by a fixed angle in relation to each other. To verify the stability of the instrument we designed the procedures of collimation and comparison. The collimation consists of using the heliometer for measuring the diameter of an artificial solar image specifically created for this purpose. The comparison is performed by measuring the residual unfold of a punctual image after been unfold by two opposed heliometers. The heliometric approach allows the measurement of the solar diameter at any heliolatitude and can be undertaken as often as desired. Computer programs have been developed for automated image acquisition and analysis. The optical and mechanical design has been performed by using 3D computer aided design software.

    This study sought to evaluate the incidence of cardiorenal syndrome (CRS) type 1 in a coronary care unit and its association with hospital mortality within 30 days of admission, as well as other epidemiological characteristics. The medical records of all the patients who were hospitalized with the diagnosis of acute heart failure in a 4-year period were reviewed. CRS type 1 was characterized by the presence of acute heart failure and an elevation of serum creatinine ≥0.3mg/dL in comparison to the baseline creatinine calculated by the MDRD75 equation and/or the elevation of ≥50% of the admission serum creatinine within a 48 h period. The incidence of CRS type 1 was 27.87%, 95% CI: 20.13-36.71 (34 of 122). There was a higher frequency of CRS type 1 in those patients who were admitted with the diagnosis of cardiogenic shock (adjusted RR 2.02, 95% CI: 1.20-3.93, p=0.0378) and in those with higher hemoglobin levels (p=0.0412). The CRS type 1 was associated with an increase of 30-day mortality (HR: 4.11, 95% CI: 1.20-14.09, p=0.0244). The incidence of CRS type 1 in the coronary care unit found in our study is similar to those found in foreign studies. The history of stroke and the higher values of hemoglobin were associated with a higher incidence of cardiorenal syndrome type 1. Patients with CRS type 1 had a higher hospital mortality within 30 days of admission. Copyright © 2014 Instituto Nacional de Cardiología Ignacio Chávez. Published by Masson Doyma México S.A.

    The Instituto Nacional de Enfermedades Neoplásicas was established by the government of Peru as an institution for the treatment of cancer patients in 1939; it has existed under different names until the current title was adopted in 1952. Between 1980 and 1987, attendance increased by 70% and a new and larger facility came into use at the beginning of 1988. This institution has national responsibility for cancer prevention, detection, treatment, education, and research and is currently organizing satellite treatment centers in other parts of the country. More than 80% of the medical staff has been trained in the institute's residency program, the majority of whom received additional postgraduate training in the United States and Europe; 90% of the medical staff hold academic appointments in medical schools. In 1952 the Institute became the first hospital in Peru with a formal postgraduate training system for various medical disciplines, including surgical oncology and medical oncology. So far we have trained about 500 surgical oncologists who are working in all parts of Peru. The Maes-Heller Institute for Cancer Research forms part of the National Cancer Institute complex. Research will be directed mainly toward new diagnostic and therapeutic approaches, multidisciplinary tumor therapy, and large-scale cancer screening. The Institute focuses on early detection and prevention of cancer and is active in breast self-examination education and antismoking campaigns. It enjoys community support evidenced in the women's organization, Adainen, involved in fundraising; 460 women volunteers give at least 4 hr service per week to the Institute. The Institute has grown from 9,000 patients seen per year in its early days to 215,000 attendances in 1986.

  15. The origin of oriented lakes in the Andean foreland, Parque Nacional Torres del Paine (Chilean Patagonia)

    2008-05-01

    The Parque Nacional Torres Del Paine and surrounding area in the Magallanes foreland basin in Chilean Patagonia is the site for numerous lakes fed by glaciers and rivers in the Andean highlands to the west. The lakes are elongate and have conspicuously systematic orientations. We hypothesize that the origin of the oriented lakes lies in the fault system, composed of a right-lateral strike-slip fault set oriented 58° from north, a left-lateral strike-slip set oriented 87°, and a thrust fault set oriented 167°, that exists within the underlying rocks. To test this hypothesis quantitatively, we determined the shape and orientation of the lakes by fitting each lake with an ellipse of appropriate aspect ratio, and later with multiple ellipses consistent with the composite geometry of some lakes. We then examined the faults in the area in terms of their kinematics, orientation and distribution. The distribution of lake orientations showed three distinct groups which appear to correspond to the three main fault groups. For lakes fitted with multiple ellipses, the difference in means between the right-lateral, left-lateral, and thrust faults and their corresponding groups of lakes are 3.05°, 1.57°, and 5.17°. Using a Kolmogorov-Smirnov (K-S) statistical test to compare the orientations of faults with respect to the lakes suggests that there is not a strongly significant difference between the fault orientations and the corresponding lake groups. These results indicate that the faults have a profound control on the orientation, shape, and distribution of the lakes. We attribute this to faults and their damage zones being weaker and therefore prone to a faster rate of erosion, and to stress perturbations associated with discontinuous faults resulting in localized high density fracturing and surface subsidence. These results have implications for lake and drainage system morphologies in other foreland basins along the Andes and other similar settings.

    The highlands of northeastern Honduras remain under-characterized in terms of biological diversity, as exemplified by the regularity of new amphibian and reptile taxa discoveries. Following the recent description of a new species of Nototriton from the Sierra de Agalta in northeastern Honduras, we report the discovery of a second new species of Nototriton from the nearby Parque Nacional Montaña de Botaderos. This new taxon, Nototriton mime sp. nov., is distinguished from other Nototriton by its distinctive pale brown dorsal coloration in adult males, relatively large nares, a relatively broad head, mitochondrial sequence divergence, and phylogenetic relationships, and is geographically isolated from other populations of Nototriton.

    A distinctive new species of Atelopus is described from Parque Nacional Chirrip6 Grande, Cordillera de Talamanca (3,400-3,500 m). It closely resembles populations of the Atelopus ignescens complex from the Andes of northern Ecuador and southern Colombia. It differs most significantly from these frogs in the pattern of spiculae and coni development on the throat, chest, hands and feet. The Costa Rican species appears to be an outlier of the complex inexplicably separated geographically from its nearest allies by an over land distance of about 1,600 km.

    Tissue banking is a complex operation concerned with the organisation and coordination of all the steps, that is, from donor selection up to storage and distribution of the final products for therapeutic, diagnostic, instruction and research purposes. An appropriate quality framework should be established in order to cover all the specific methodology as well as the general aspects of quality management, such as research and development, design, instruction and training, specific documentation, traceability, corrective action, client satisfaction, and the like. Such a framework can be obtained by developing a quality management system (QMS) in accordance with a suitable international standard: ISO 9001:2000. This paper presents the implementation process of the tissue bank QMS at the Instituto Nacional de Investigaciones Nucleares in Mexico. The objective of the paper is to share the experience gained by the tissue bank personnel [radiosterilised tissue bank (BTR)] at the Instituto Nacional de Investigaciones Nucleares (ININ, National Institute of Nuclear Research), during implementation of the ISO 9001:2000 certification process. At present, the quality management system (QMS) of ININ also complies with the Mexican standard NMX-CC-9001:2000. The scope of this QMS is Research, Development and Processing of Biological Tissues Sterilised by Gamma Radiation, among others.

    The mineral resources of an area of 40,000 sq km, principally in the Department of Antioquia, but including small parts of the Departments of Caldas, C6rdoba, Risaralda, and Tolima, were investigated during the period 1964-68. The area is designated Zone II by the Colombian Inventario Minero Nacional(lMN). The geology of approximately 45 percent of this area, or 18,000 sq km, has been mapped by IMN. Zone II has been a gold producer for centuries, and still produces 75 percent of Colombia's gold. Silver is recovered as a byproduct. Ferruginous laterites have been investigated as potential sources of iron ore but are not commercially exploitable. Nickeliferous laterite on serpentinite near Ure in the extreme northwest corner of the Zone is potentially exploitable, although less promising than similar laterites at Cerro Matoso, north of the Zone boundary. Known deposits of mercury, chromium, manganese, and copper are small and have limited economic potentia1. Cement raw materials are important among nonmetallic resources, and four companies are engaged in the manufacture of portland cement. The eastern half of Zone II contains large carbonate rock reserves, but poor accessibility is a handicap to greater development at present. Dolomite near Amalfi is quarried for the glass-making and other industries. Clay saprolite is abundant and widely used in making brick and tiles in backyard kilns. Kaolin of good quality near La Union is used by the ceramic industry. Subbituminous coal beds of Tertiary are an important resource in the western part of the zone and have good potential for greater development. Aggregate materials for construction are varied and abundant. Deposits of sodic feldspar, talc, decorative stone, and silica are exploited on a small scale. Chrysotils asbestos deposits north of Campamento are being developed to supply fiber for Colombia's thriving asbestos-cement industry, which is presently dependent upon imported fiber. Wollastonite and andalusite are

  2. The influence of climate change on wine production - the case of the Touriga Nacional grape variety (Quinta dos Termos, Portugal)

    The regional and local climate, heavily influenced by global climate change, has strong implications for agriculture. Wine production which has specific characteristics in terms of climate and soil is undoubtedly one of the economic activities strongly influenced by climate change. Quinta dos Termos located in Beira Interior (Belmonte, Portugal) is the largest wine producer in the DOC Beira Interior region, producing premium to hiper premium wines of excellence, marketed at both national and international levels, and cultivates the vineyards according to the rules of Integrated Crop Management. Moreover, grapes are free from herbicides, pesticides or any other chemicals that can be harmful to the environment and health. These factors have contributed to the socio-economic development of the region, creating wealth, favoring employment and promoting tourism. The quality of the wines produced by Quinta dos Termos result from its terroir, given its granite region, the sun exposure, the wind protection, the atmospheric humidity and temperature, the soil water content, the mineralogical/organic composition and soil porosity. These factors favor unique conditions for the cultivation of Touriga Nacional grape variety, which is recognized by its extremely complex color and aroma, which allows the production of wines with great balance and a good ageing potential. Touriga Nacional, a red grape variety of Portuguese origin with high qualitative excellence and reputation and much appreciated worldwide, is versatile to several types of soils and resistant to high thermal amplitudes. Nevertheless, the climatic changes that has been gradually verified, the type of crop management, and in particular the reputation of Touriga Nacional grape variety, may be compromised in the long term, given that these characteristics are strongly influenced by the climate and soil. Aware of that, Quinta dos Termos has been performing a monitoring of the vineyards in terms of pedological treatment

    The Atlantic Forest is considered one of the world's biological diversity hotspots, and is increasingly threatened by the rapid destruction and fragmentation of its natural areas. The caddisflies (Trichoptera) of Itatiaia massif, an Atlantic Forest highland area, are inventoried and cataloged here. The catalog is based on examination of bibliographies, field work on many localities of Itatiaia massif (including Parque Nacional do Itatiaia — PNI), and the entomological collection Professor José Alfredo Pinheiro Dutra (DZRJ), Universidade Federal do Rio de Janeiro. A total of 92 species are recorded, representing about 17% of the known Brazilian Trichoptera fauna. Leptoceridae, Hydropsychidae, and Philopotamidae are the families most represented. The high species richness, as well as the remarkable patterns of species distribution, may be related to the characteristics of Mantiqueira mountain range. PMID:22958122

    Radiated seismic energy is a valuable parameter in assessing the size and source characteristics of an earthquake. We study aftershocks of the 20 March 2012 earthquake (Mw7.5) in Ometepec-Pinotepa Nacional,located in the subduction zone of the Pacific coast of Mexico, with the purpose of examining the distribution of the scaled seismic energy (Es) with seismic moment (Mo), Es/Mo, over the main event's rupture area. We estimate Es from regional velocity and acceleration records. For some, larger, aftershocks we also estimate Es from teleseismic data. Preliminary energy estimations suggest that aftershocks closer to the trench have a smaller Es/Mo ratio. In contrast, Es/Mo is larger for events closer to the coast (near the epicenter of the mainshock).

    A cross-sectional study that included 100 units of umbilical cord blood (UCB) was conducted to evaluate the minimum criteria of cellularity in UCB units, according to NetCord standards at Instituto Nacional Materno Perinatal in Lima, Peru. The volume, total count of nucleated cells by hematological tests and total number of CD34+ as well as cell viability by flow cytometry were determined. The study revealed that 56% of UCB units do not fulfill the minimum criteria of cellularity to be cryopreserved in an umbilical cord blood bank. Furthermore, the UCB units of newborns who weighed more and were female had a higher volume and cell count. In conclusion, these variables must undoubtedly be considered to optimize the collection of UCB units and obtain greater cell counts that enable the storage of high-quality units in a future umbilical cord blood bank in Peru.

    Ambient dose equivalent values were determined in several sites at the Instituto Nacional de Cancerología, Departmento de Medicina Nuclear, using TLD-100 and TLD-900 thermoluminescent dosemeters. Additionally, ambient dose equivalent was measured at a corridor outside the hospitalization room for patients treated with 137Cs brachytherapy. Dosemeter calibration was performed at the Instituto Nacional de Investigaciones Nucleares, Laboratorio de Metrología, to known 137Cs gamma radiation air kerma. Radionuclides considered for this study are 131I, 18F, 67Ga, 99mTc, 111In, 201Tl and 137Cs, with main gamma energies between 93 and 662 keV. Dosemeters were placed during a five month period in the nuclear medicine rooms (containing gamma-cameras), injection corridor, patient waiting areas, PET/CT study room, hot lab, waste storage room and corridors next to the hospitalization rooms for patients treated with 131I and 137Cs. High dose values were found at the waste storage room, outside corridor of 137Cs brachytherapy patients and PET/CT area. Ambient dose equivalent rate obtained for the 137Cs brachytherapy corridor is equal to (18.51±0.02)×10-3 mSv/h. Sites with minimum doses are the gamma camera rooms, having ambient dose equivalent rates equal to (0.05±0.03)×10-3 mSv/h. Recommendations have been given to the Department authorities so that further actions are taken to reduce doses at high dose sites in order to comply with the ALARA principle (as low as reasonably achievable).

    ABSTRACT OBJECTIVE Our main objective was to analyse how the evolution of household assets ownership affected the Indicador Econômico Nacional (IEN – National Wealth index) and to point out the most stable assets and which lost importance more quickly. METHODS We analysed the trend of the ownership of each IEN variable and the distribution of the households’ scores. We calculated the correlation coefficients of each variable separately with the IEN score and the household income. We also evaluated how the changes of the score distribution over time affected the validity of the published reference cut-points. We used data from consortium surveys conducted every two years from 2002 to 2014 in the city of Pelotas, Brazil. RESULTS An increase in the educational level of household heads and in the ownership of all IEN assets, except radio and telephone, was observed in the study period. In general, the correlation of the assets with the IEN scores decreased over time. There was an increase in the score, with a consequent increase in the quintiles cut-points, but the distance between these cut-points had no significant variation. Thus, the reference cut-points for Pelotas, quickly became outdated. CONCLUSIONS Some assets showed greatly reduction on its importance for the indicator, and the reference cut-points became obsolete very quickly. It is essential for a standardized wealth (or asset) index with research purposes to be updated frequently, especially the cut-points of reference distribution. PMID:28273231

    Annular pancreas (AP) is a rare congenital anomaly due to malrotation of the pancreatic ventral yolk. Although it has been described in young and middle age adults it predominates in children. Its clinical picture is that of duodenal obstruction or acute pancreatitis episodes. In this paper we report four cases of AP that were seen at the Instituto Nacional de la Nutricion Salvador Zubiran in Mexico City. Three were females and three were less than twenty years old. In one case the diagnosis was established at birth and the operation done in another hospital. In another patient a diagnosis of pyloric hypertrophy was made and a pyloroplasty was performed. This young man was admitted in our hospital because of abdominal pain and hyperamylasemia. An eighty four year old woman was seen due to abdominal pain, nausea and vomit. In all cases the diagnosis of AP was carried out with radiological studies and confirmed by laparotomy. Surgical procedures consisted of duodenal-duodenal anastomosis in two, sphincteroplasty in one, and gastrojejunoanastomosis in the other. Two patients are asymptomatic, one died in the postoperative period, and one was lost for follow up. These four cases represent all the experience of our institute and correspond to one case in 36,735 admissions.

    We evaluated 500 endoscopic retrograde cholangiopancreatographies (ERCP) performed on 422 patients during a 5-year period in the Gastrointestinal Endoscopy Department, Instituto Nacional de la Nutrición Salvador Zubirán, México, D.F. ERCP combines endoscopic and radiologic techniques in order to obtain high quality opacification of pancreatic and biliary ducts. The rate of success for cannulation was 90%; desired duct opacification was possible in 89%. The most frequent indication for ERCP was to establish the differential diagnosis for jaundice; biliary stones in the common bile duct was the most frequent diagnosis, followed by normal biliary ducts. Pancreatography was normal in 74% of patients. ERCP complications were detected in 5.6%; fever and transient pain was the most common complaint in 1.6%. Mortality attributable to the procedure was 0.8%. From histological corroboration of cases by surgery or postmortem studies, diagnostic sensitivity was 92%, specificity 76%, positive predictive value 96% and a prevalence of 89%. We conclude that ERCP is highly sensitive and specific in diagnosing bilio-pancreatic-duodenal disease. Our results are comparable to other's experiences published throughout the world.

    Sponges constitute one of the most diverse and abundant animal groups in the marine tropical benthos especially in coral reefs, though poorly studied to species level. The aim of this study is to characterize the sponge community along a depth gradient at Isla Larga (Parque Nacional San Esteban, Venezuela) fringe reef. Net and total sedimentation, roughness index, sponge species richness, density and proportion of the bottom covered by sponges, were evaluated at seven depths (1, 3, 6, 9, 12, 15, 18 m), 17 species were identified grouped in 10 demosponges families. The highest densities and coverage corresponded to 6 m of depth (6.03ind/m2; 11%), that coincides with the lowest net sedimentation and highest substrate heterogeneity. Most abundant species were Desmapsamma anchorata, Amphimedon erina and Scopalina rueztleri. Principal component analysis divided this community in three zones according to depth. The shallow zone of the reef (1 and 3 m), where wave force and high irradiance exert a constant stress sponges, shows the lowest density and coverage by sponges. In contrast, medium depth (6, 9 y 12 m) and deep zone (15 y 18 m) with lower light and sedimentation levels seem to enhance sponge growth and survival that are reflected on the higher densities and coverage of sponges.

    To assess the features of asymptomatic patients with acute ST segment elevation myocardial infarction who presents to the emergency with more than 12h of evolution, and if there is a benefit of an invasive versus medical therapy. Retrospective, cohort study from January 2012 to December 2014, we compare the outcomes at 6 and 12 months of follow up of the invasive group versus the conservative group. There were no differences in outcomes at 12 months between an invasive versus a conventional strategy; but, looking at the reperfusion state, we found more risk of death and heart failure at 12 months in the no-reperfused group versus the reperfused group (40% versus 0%, OR: 2, CI: 1.2-3.1, p=0.028 for mortality and 53% versus 0%, OR: 2.2, CI: 1.3-3.98, p=0.007 for heart failure). In patients with ST elevation acute myocardial infarction with more than 12h of evolution, the invasive strategy with optimal reperfusion is better than the conservative management or no reperfusion in terms of less mortality and heart failure at 12 months of follow up.

A retrospective, descriptive study from January of 1997 to January 2008, analyzed 152 pregnancies complicated by fetuses with major craniofacial defects, diagnosed at the Department of Fetal Medicine of the National Institute of Perinatology. Data were obtained from patients clinical records. . The mean age was 28 +/- 8 years, with the largest number of cases between 20 and 24. The mean gestational age at diagnosis was 27.5 +/- 6.4 gestational weeks. The average termination of pregnancy was at 35 +/- 5 gestational weeks. In 43.4% of cases there were no major structural defects associated with the facial defect. The most commonly associated structural alterations were cerebral, cardiac, and limb abnormalities. Karyotyping was performed in only 57 cases, and was abnormal in 25. Structural ultrasound should be performed on all pregnant women between weeks 18 and 24 for detection of major craniofacial defects. Where defects are found, a thorough review of other structures should be carried out to determine whether the defects are syndromic. A systematic and multidisciplinary approach is essential to providing the best care and appropriate advice to parents.

    In this paper we present the first comprehensive analysis of the 1 MV AMS system at the Centro Nacional de Aceleradores (CNA, Seville, Spain) for 236U studies in environmental samples. In the last years, this radionuclide has become key in the AMS community, due to the very demanding 236U/238U abundance sensitivities required for general applications. As we demonstrate, the AMS system at the CNA is able to achieve sensitivity for the 236U/238U ratio of about 3 × 10-11 despite its compact design. The use of "239Pu"/238U ratio as a proxy for "236U"/235U background correction is proposed and tested with natural samples that were also studied on the 600 kV Tandy AMS system at the ETH Zürich. This correction is significant in the CNA case, due to the low mass resolving power of the low-energy spectrometer and to the lack of a third filter on the high-energy side. With the measurement of reference solutions supplied by the Institute for Reference Materials and Methods (IRMM-075), and reference natural matrixes provided by the International Atomic Energy Agency (IAEA-Soil-6, IAEA-375; 384; 386 and IAEA-RGU), we show that the 1 MV AMS system at the CNA can be routinely used for determinations of anthropogenic 236U at environmental levels.

    In this work we present the most recent improvements performed by our group on 10Be measurements on the 1 MV AMS system recently set up at the CNA (Centro Nacional de Aceleradores), in Seville (Spain). Our efforts have been focused on the study of the viability of our system for BeO and BeF - measurements. To achieve this, different standard materials have been measured to demonstrate the reliability of the system for BeO measurements in a wide 10Be/ 9Be atomic ratio range and several environmental samples have been studied both at the 1 MV AMS CNA facility and at the 6 MV AMS ETH-PSI facility of Zurich to validate our measurements. The results show a good agreement between laboratories. New experiments also have been carried out selecting 1+ and 2+ charge states at the exit of the accelerator and inserting Si 3N 3.1 foils with different thicknesses to separate 10Be from its isobar, 10B. The influence of each foil on the overall transmission (detected 10Be compared to BeO - injected into the accelerator) and background level was also assessed. In addition some tests were also done to assess the viability of BeF 2 and BaBeF 4 measurements at our system. Several metal matrices and cathode preparation procedures for BeO samples were investigated to maximize current and cathode lifetime.

We used five microorganisms isolated at the Archivo Nacional: Streptococcus sp. (1), Listeria sp. (2) and Candida guillermondii (3), and Escherichia coli ATCC 25922 (4) and Saccharomyces cerevisiae (5) as references. We applied this magnetic field of extremely low frequency, 60 Hz/220 V (3 mT), for two hours to these microorganisms on three culture tubes with distilled water and nutrient broth. Then we inoculated 0.1 mL in the following solid culture mediums on Petri dishes: CromoCen SC Agar (1 and 2), Potato Dextrose Agar (3), CromoCen DC 4227 (4) and Malt Extract Agar (5). The colonies were counted (log CFU/mL) by digital processing of the images of Petri dishes using the MatLab ® tool. We observed a statistically significant stimulation (p=0.05) in the quantity of treated colonies as compared to controls, which was higher in nutrient broth than in distilled water, and in bacteria (nutrient broth and treated colonies: 9.43 to 10.62 CFU/mL) as compared with yeasts (nutrient broth-treated colonies: 8.31 to 8.79 CFU/mL). In decreasing order, stimulation was as follows: Listeria sp., E. coli ATCC 25922, Streptococcus sp., C. guillermondii and S. cerevisiae . We concluded that the magnetic field applied had a stimulating effect on the microorganisms under study, which increases the risk to the health of staff and visitors at the Archivo Nacional .

    We describe the fourth species of nurse-frog genus Allobates occurring in the southeastern Brazilian Amazonia. The new species is sympatric with Allobates femoralis, Allobates masniger and Allobates magnussoni, and inhabits the margins of streams in forested areas within Parque Nacional da Amazônia, on the western bank of the Tapajós River. Snout-to-vent length ranges between 14.9-16.1 mm among males and 15.6-16.5 mm among females. The species is distinguished by the light brown background color of dorsum, with irregular dark brown blotches appearing from eye level to the urostyle region. In life, ventral surfaces of males are golden yellow on throat and chest, and white to yellow on abdomen. Ventral surfaces of females are predominantly white, except for light yellow on chin. The dark brown lateral band has a diffuse lower edge ventrolaterally. Dorsal surface of thigh is cream, with a longitudinal dark brown band extending dorsally from vent to knee. Tail musculature of tadpoles is robust, bifurcating dorsally over the body and reaching about two-thirds of the body length. Advertisement calls consist predominantly of continuous pairs of notes, but other note arrangements are also emitted. Notes have ascending frequency modulation and average peak frequency ranging between 5.3-5.9 kHz. First and second notes of the same note pair are similar in amplitude, duration and frequency spectrum. Successive note pairs are split by approximately regular silent intervals (0.30-0.49 s). The species lays its eggs inside rolled or folded dead leaves on the leaf litter. Egg capsules and jelly nests are opaque.

    The superficial mycoses are very common infectious diseases and therefore are a frequent reason for medical consultation. The aim of this study was to determine the diagnostic frequency of superficial mycoses in the Mycology Department of the Instituto Nacional de Higiene "Rafael Rangel" during 14 years (2001-2014). A retrospective cross-sectional study was performed to review the mycological records of patients with presumptive diagnosis of superficial mycosis. Nails, hairs and epidermal scales were the processed samples. The identification of fungi was performed by macro and microscopic observation of colonies and biochemical and physiological tests, as required of the isolated agent. For the investigation of Malassezia spp. only direct examination was performed. Of the 3 228 samples processed, 1 098 (34%) were positive and their distribution according to the etiological agent was: dermatophytes 79.5%; 10.9% yeasts; non-dermatophytes fungi 5.1% and 4.5% Malassezia spp. The most frequently isolated dermatophyte was Trichophyton rubrum Complex (70.1%), followed by T mentagrophytes complex (15.1%), Microsporum canis (9.4%) and Epidermophyton floccosum (4%). The most frequent ringworms Were: Tinea unguium (66.8%), followed by Tineapedis (16.4%) and Tinea capitis (8.1%). Candida parapsilosis complex (37.5%) was the most frequently isolated yeast and Fusarium spp. (53.6%) was the most isolated among non-dermatophyte fungi, followed by Aspergillus spp. (19.6%) and Acremonium spp. (10.7%). The identification of the etiological agent is essential to guide appropriate treatment. This study constitutes an important contribution to the knowledge of the epidemiology of superficial mycoses in our country.

    A total of 1,356 kidney transplants has been performed in the Hospital de Especialidades del Centro Médico Nacional de Occidente, IMSS, in Guadalajara Mexico, including 935 in the past 8 years. This represents an important increase of this activity in our country. Of the total transplants, 1,218 (90%) were from living donors and only 138 (10%) were from cadaveric donors, a number that we hope to increase. Most recipients were young adults, with an average age of 31 years old. The overall one-year graft and patient survival rates for living-donor kidney recipients were 90% and 82%, and for cadaveric kidney recipients they were 80% and 70%, respectively. Acute rejections occurred in 17% and chronic allograft nephropathy was diagnosed in 7% of our kidney transplant recipients. The main cause of patient death was infection, frequently invasive CMV. Cardiovascular complications were a relatively infrequent cause of death as has been seen in other international series. Hepatitis B and C have been widley studied. Hepatitis C is the most prevalent viral infection in our population. Both living and cadaveric donors in our series were young, which may explain the good results. We have had very few complications among living donors and no mortality. Two donors developed chronic renal insufficiency after the kidney donation (0.001%). This excellent safety record reflects the experience of our team. We hope to increase the number of cadaveric transplant donors with the renewed interest in enlarging the transplantation programs in Mexico while maintaining our high percentage of living donors in order to benefit more patients.

    Introducción: en apoyo a la problemática de sobrepeso y obesidad en México, en el 2010 se publicó el Acuerdo Nacional para la Salud Alimentaria. A nivel escolar, los comodatarios se consideraron fundamentales para cumplir con ciertos compromisos. El objetivo de esta intervención fue capacitar a comodatarios de los Establecimientos de Consumo Escolar (ECE) en cuanto a los criterios establecidos en los “Lineamientos Generales para el Expendio y Distribución de Alimentos en Planteles de Educación Básica.” Métodos: participaron 13 ECE en San Luis Potosí. Con base en un diagnóstico inicial, se diseñó un curso-taller de 5 sesiones. Se evaluaron conocimientos en materia alimentaria al inicio y al final de las sesiones. Se obtuvo el porcentaje de apego en cuanto a higiene general, preparación y distribución de alimentos, al inicio, al mes y a los dos meses postintervención. Resultados: los comodatarios presentaron pocos conocimientos en los objetivos que persigue el “Acuerdo” en grupos y combinación de alimentos así como en lectura de etiquetas; con cambios significativos en los dos últimos tras la intervención. El porcentaje inicial de cumplimiento en higiene general fue del 60 %, con un incremento de casi 20 % postcapacitación. La preparación y distribución de alimentos no presentaron cambios significativos. Conclusiones: los comodatarios adquirieron conocimientos sobre los lineamientos que debe cubrir un ECE, sin ponerlos en práctica, dado el impacto que ello implica en su economía.

  9. Differential physiological response of the grapevine varieties Touriga Nacional and Trincadeira to combined heat, drought and light stresses.

    Worldwide, extensive agricultural losses are attributed to drought, often in combination with heat in Mediterranean climate regions, where grapevine traditionally grows. The available scenarios for climate change suggest increases in aridity in these regions. Under natural conditions plants are affected by a combination of stresses, triggering synergistic or antagonistic physiological, metabolic or transcriptomic responses unique to the combination. However the study of such stresses in a controlled environment can elucidate important mechanisms by allowing the separation of the effects of individual stresses. To gather those effects, cuttings of two grapevine varieties, Touriga Nacional (TN) and Trincadeira (TR), were grown under controlled conditions and subjected to three abiotic stresses (drought - WS, heat - HS and high light - LS) individually and in combination two-by-two (WSHS, WSLS, HSLS) or all three (WSHSLS). Photosynthesis, water status, contents of H2 O2 , abscisic acid and metabolites of the ascorbate-glutathione cycle were measured in the leaves. Common and distinct response features were identified in the different stress combinations. Photosynthesis was not hindered in TN by LS, while even individual stresses severely affect photosynthesis in TR. Abscisic acid may be implicated in grapevine osmotic responses since it is correlated with tolerance parameters, especially in combined stresses involving drought. Overall, the responses to drought-including treatments were clearly distinct to those without drought. From the specific behaviours of the varieties, it can be concluded that TN shows a higher capacity for heat dissipation and for withstanding high light intensities, indicating better adjustment to warm conditions, provided that water supply is plentiful.

    Species of Mesocoelium Odhner, 1901 (Digenea) are generally similar and are often difficult to distinguish. Currently there are 42 specimens of this genus held in the Colección Nacional de Helmintos (CNHE) of the Instituto de Biología, Universidad Nacional Autónoma de Mexico, which previously have been assigned to three species: M. monas Rudolphi, 1819, M. travassosi Pereira & Cuocolo, 1940 and M. leiperi Bhalerao, 1936. Upon reevaluation of these specimens it was determined that 27, could not be assigned to species level and 15 could only be assigned to body type (carli and leiperi) because of the poor conditions of preservation of the material. The remaining 15 specimens were of sufficient quality to be identified to species and were found to represent M. americanum Harwood, 1932, M. danforthi Hoffman, 1935, M. meggitti Bhalerao, 1927, M. cf. americanum Harwood, 1932, and M. cf. danforthi Hoffman, 1935. Neither M. monas nor M. travassosi could be confirmed among these specimens; however, Mesocoelium meggitti (syn. M. travassosi) was confirmed. Mesocoelium danforthi is recorded for the first time in the Mexican collection. The presence of M. cf. gonocephali Singh, 1967 and M. cf. microon Nicoll, 1914 also among the 15 specimens of sufficient quality to be identified to species, needs to be confirmed through collects of new material. Finally, in future studies, we propose to improve the quality of specimens by fixing them considering the modifications to this process proposed herein, and compliment these morphological studies with molecular studies.

    This work looks into the meanings of nursing from the point of view of the students in an undergraduate nursing degree program. The research took place at the Universidad Nacional de Lanús using semistructured interviews - eleven individual and seven group interviews - carried out between 2008 and 2010. A content analysis was then undertaken and the most relevant meanings in relation to four themes were selected: reasons for studying nursing, what nursing is, nursing as a profession, and working in nursing. Multiple and diverse ways of defining nursing were uncovered. Utilizing some conceptual developments from the sociology of the professions, the meanings were organized into four conceptualizations that represent ways of understanding nursing: as a vocation, as a profession, with a utilitarian perspective and with a community perspective. The conclusions reached indicate the need to broaden the debate regarding the types of nurses that are being trained.

    In a study conducted in the gallery forest of the Vale doVeu de Noiva in the Parque Nacional da Chapada dos Guimarães, Mato Grosso state, chemical baits were used to attract and sample male orchid bees. From September 2003 to July 2005, male euglossine bees were captured monthly, from 8:00 a.m. to 4:00 p.m. as they arrived at the baits. Of the 264 males captured, eight males belonged to Aglae caerulea Lepeletier & Serville, a cleptoparasitic euglossine species that presumably occurred only in the Amazon basin. Therefore, the occurrence of A. caerulea in this study area extends its geographical distribution range by approximately 2,400 km southwards in South America, as it is now recorded in both the Amazon and Platina basins.

    Anorexia-cachexia is a frequent syndrome among cancer patients, specially in late stages: the global prevalence of para-neoplastic anorexia-cachexia ranges between 20-40% in the diagnostic stage and between 70-80% in the late stage of the disease. The co-existence of functional or structural digestive abnormalities is frequently observed among cancer patients; this is a consequence of the tumor growth and of those systemic phenomena related to metabolism, which are affected by the relationship tumor-host specific to anorexia- cachexia. This study aimed at establishing the frequency of anorexia-cachexia, as well as its relationship to GI symptoms in the context of palliative care patients at the Instituto Nacional de Cancerología, México City. Analytic cross-sectional study including 100 patients diagnosed with late-stage cancer, age range 18-80, and a Karnofsky score > 50, as well as an ECOG <2; patients with a bad general health status were not allowed in the study. After reviewing inclusion and exclusion criteria, participants fulfilled the FAACT questionnaire, as well as the EGS. Patients recruitment was carried out by the Instituto Nacional de Cancerología. Results and discussion: Results show that 61% (n=61)of the patients had anorexia-cachexia, and 39% (n=39)did not. 56% of the sample participants (n=34) were women, and 44% (n=27) were men. GI symptoms associated with anorexia-cachexia were: nausea (p= 0.0001), vomiting (p=0.004), early satiety (p=0.0005), dysgeusia(p=0.0005) and dysphagia (p=0.001). Anorexia and cachexia are among the most devastating and frequent symptoms in late-stage cancer patients and they are also associated with GI symptoms affecting the physical, psychosocial and existential aspects of the patient's life. Data from this research validate the importance of an early nutrition support in palliative patients so that they can achieve a better quality of life. Copyright AULA MEDICA EDICIONES 2014.

    The purpose of this study was to determine the frequency of different Central Nervous System Tumors (CNST) diagnosed at the Instituto Nacional de Neurología y Neurocirugía (National Institute of Neurology and Neurosurgery) from Mexico City over a 10-year period (1990 to 1999) by means of a hospital survey. This institute is a reference hospital that provides medical attention to a very high number of adult neurological patients every year (approximately 6,000 new patients per year besides emergency cases). From a total number of 2,041 CNST cases, we found that the most frequent tumors were those affecting the neuroepithelial tissue (32.8 %), followed by tumors of the anterior pituitary gland (26.2 %) and tumors of the meninges and similar tissues (24.1 %). In both, male and female patients the higher frequency of CNST was found in patients whose age ranged from 25 to 44 years, and CNST were slightly more frequent in women than in men. Most of the CNST patients lived in the southern districts of Mexico City, it could be because of the great number of people living in the southern districts of the city, or perhaps due to the presence of certain yet unidentified environmental carcinogenic substance in this area. Since CNST are among the more frequent malignant neoplasms, it is necessary to improve the registration system to include frequency, prevalence, incidence and mortality of these diseases in Mexico, in order to plan health policies like in developed countries.

    By 1960, México's Manicomio General (General Asylum) could no longer fulfill the functions for which it was created so implementation of the so-called Castañeda Operation began, an initiative designed to close down and relocate psychiatric patients to other institutions. At that time, Dr. Manuel Velasco-Suárez was in charge of the General Direction of Neurology, Mental Health and Rehabilitation, and planned to create the Institute of Neurology on a site he already possessed for its construction. The Asylum was a dependency of the aforementioned Direction and Velasco- Suárez decided that some patients at the Castañeda could be moved to the old hacienda house that stood on that terrain. Thus was born the Bernardino Álvarez Farm Hospital. A year later, in 1961, the Farm School for the Weak-Minded, also named Bernardino Álvarez was established there as well. This paper examines the history of these two institutions as antecedents to the Instituto Nacional de Neurología y Neurocirugía.

    We use near-field accelerograms recorded by the very broadband seismographic station of PNIG to locate the Pinotepa Nacional earthquake of 27 March, 1996 (Mw = 5.4) and to determine its source parameters. The data from PNIG on P and S arrival times, the azimuth of the arrival of P wave, and the angle of incidence of the P wave at the free surface permit the determination of the location (16.365° N, 98.303° W, depth = 18 km) and the origin time (12:34;48.35) of the earthquake.The displacement seismograms of the earthquake clearly shows contribution from the near-field terms. We compute a suite of synthetic seismograms for local mechanisms in the vicinity of the mechanism reported by the U.S. Geological Survey (USGS) and compare them with the observed seismograms at PNIG. The point whose synthetics fit the observed records well has the following parameters: seismic moment, M0 = 1.2 × 1024 dyne-cm; source time function: a triangular pulse of 0.9 sec duration; fault plane: strike = 291°, dip = 10°, and rake = 80°. The location and the source parameters obtained from the analysis of PNIG records differ significantly from those reported by the USGS. This demonstrates again, what has been shown by some previous researchers, that high-quality recordings from a single near-field station can considerably improve the estimation of the source parameters of an earthquake.

Its guiding motto says: "I'll be a shield to stop the wind that wants to erase the imprint of men that shaped the history of the School of Medical Sciences by their work." To accomplish the tasks, general and particular objectives were settled. The Museum has a Library divided in three sections: Classical, Contemporary and Virtual. It counts with a specialized Information and Documentation Centre. Courses about different topics are given as well as the course of History of Medicine for Grade and post grade careers, completing with humanistic contents, the students education exclusively scientific and technical. For high school and Bachelor students there is a program called: "Education - Apprenticeship strategies at the Museum". These strategies are arranged to fit the programmes and levels of formal education for educational institutions. The heritage of the Museum consists of more than a thousand apparatus and tools that served the research and instruction at the different professorships of the School of Medical Sciences. Many of them obsolete they allow us to understand the evolution of science and technique, within the broad field of Health Science, since the creation of the School of Medical Sciences in 1877.

    In order to describe the clinical-pathological characteristics of the cases of Eccrine Porocarcinoma (EP) found in the Instituto Nacional de Enfermedades Neoplásicas (INEN), a cross-sectional study was carried out, including all EP cases recorded between 1998 and 2009. A revision of the clinical-pathological records indentified and a new reading of the pathology slides of the cases found were performed. 19 EP cases were found, the median age of which was 64 years (range: 37-98). EP was primarily found on male patients (57.9%) and was most commonly located on the foot (21.1%), followed by the head, thorax and thigh (15.8%, respectively). In one case, EP was located on the gluteal region, and showed an unusually invasive behavior and rectal involvement. We conclude that EP is a rather uncommon entity in Peru. Its most common location is on the foot and it affects mostly male patients for the most part.

To analyze some basic elements of epidemiologic behavior of a hospital environment maternal mortality in a third level hospital during a period of 21 years. Analytical cross-sectional study, 222 maternal deaths registered at Hospital de Ginecologia y Obstetricia, Centro Medico Nacional de Occidente del Instituto Mexicano del Seguro Social, were included, during the period 1985-2005. Deaths were analyzed in three periods of 7 years each one. The analysis of results was made based on descriptive statistic. chi2 was used for comparison between periods. Maternal death ratio was 73 per 100,000 live births during the 21 years. Maternal mortality was lower in the group of women under 20 years and increase agreed maternal age. Frequency of direct obstetric deaths decreased when comparing the 3 periods. The main causes of maternal death were preeclampsia/eclampsia and obstetric hemorrhage, which were responsible for almost 50% of maternal deaths. There was no significant difference to anticipation by comparing periods, between 28 and 37% of deaths were foreseen. 98% of deaths occurred at Intensive Care Units. Direct and indirect maternal deaths show very similar values in the third period, which translates in an improvement in anticipation. It must be reinforce the simple and opportune information to the patient with regard to warning signs and the permanent medical training must be a priority at the 3 medical levels.

    The development of scientific health research requires a sustained and articulated research system that is consistent with the research priorities, as well as both internal and external funding, and availability of competent human resources. The Mining Canon, a constitutional right, has been partly used to foster applied scientific research in public universities (PU). In addition, the National Health Institute (INSTITUTO NACIONAL DE SALUD - INS) is devoted, among others, to promoting, managing and disseminating health research development at a national level. As part of these activities, a technical team was created to provide technical assistance to PU for research development using Mining Canon funds by making local adjustments to research protocols promoted by the INS and assumed by the professors-researchers at the Universities. This article aims at describing the reality of research at Peruvian public universities that have access to Mining Canon funds, as well as to elaborate on the work the INS is carrying out in order to strengthen research capabilities, starting with the development of research proposals that could potentially be funded by the Mining Canon.

    We present a review of our efforts to introduce astronomy as scientific career in Peru, showing how our astronomy outreach programs have been one of the most important keys to reach our national astronomical scientific goals, remarking the crucial role that the celebration of the IYA2009 must play, in order to promote PhD programmes in astronomy in developing countries. We show the importance of the creation of the Seminario Permanente de Astronomía y Ciencias Espaciales (SPACE) in the Universidad Nacional Mayor de San Marcos, as an academic scientific and cultural center in Peru, to support our 26 years-old "Astronomical Fridays” which are addressed to wide range of public, from schoolchildren to scientists. We also show how important was to rediscover our ancient astronomical cultural past of Incas in order to promote the construction of a Astronomical Center located near Cusco city over 4000 meters above sea level, which includes a tourist-educational observatory, a scientific optical observatory and a solar radio observatory.

    The quality of care has always been a subject of interest to the Instituto Nacional de la Nutrición "Salvador Zubirán", in order to improve its services. This interest led to the present survey which aims to evaluate the patient's global satisfaction and to identify specific problems susceptible of improvement. One hundred and seventy-one patients or relatives attending eight different services of the Institute were interviewed. Opinions about the following aspects were explored by means of service-specific questionnaires: sociodemographic characteristics, satisfaction with care, waiting periods, patient-personnel relationship, hospital environment, food quality, drug availability and costs. Results of the survey show a high level of satisfaction with the services provided, i.e. 33% of the patients considered it good, and 64% excellent. However, and in agreement with other reports, this high level of satisfaction does not necessarily reflect an absence of problems, i.e. long waiting periods, insufficient restrooms, failures in getting information about their health status, and occasional absence of drugs in the pharmacy were identified. Continuation of this kind of surveys in our setting leads not only to the identification of problems, but also to the evaluation of the impact that resulting measures may have on the patient's satisfaction.

    Comparison of clinical and autopsy findings of the cases studied between 1984 and 1988, were made at the Department of Pathology of the Instituto Nacional de la Nutricion Salvador Zubiran in Mexico City. The goal was to determine the accuracy of clinical diagnoses. The total number of cases was 429. A decreasing number of autopsies as a function of time was observed. Thus, in 1985, 34.65% of the deaths was autopsied, whereas in 1988, the number dropped to 21.16%, overall mean of 27.31%. In 229 autopsies (53.8%), 353 findings of clinical significance were found; of these, 86 were in the main diagnoses and 267 in the causes of death. There were 171 overdiagnoses with therapeutic implications, 38 in the main diagnoses and 133 in the causes of death. Overdiagnoses and underdiagnoses were most common in infectious diseases, followed by respiratory and digestive diseases, while endocrinologic and rheumatologic diseases had the highest diagnostic concordance. It was also found that the diagnostic accuracy did not improve with time of hospitalization. A brief analyses of the probable causes of the decrease in the number of autopsies is made. It is concluded that, in spite of the great advances in clinical and technological knowledge, the high frequency of disagreements between clinical and anatomical diagnoses, indicate that autopsy continues playing a key role in the quality control of medical practice. This justifies by itself the performance of necropsies.

    Manipulating Mycobacterium tuberculosis clinical specimens and cultures represents a risk factor for laboratory personnel. One of the processes that requires high concentrations of microorganisms is DNA extraction for molecular procedures. Pulmonary tuberculosis cases have occurred among professionals in charge of molecular procedures that require manipulation of massive quantities of microorganisms. This has prompted research studies on biosafety aspects of extraction protocols; however, as yet, no consensus has been reached regarding risks associated with the process. The biosafety was evaluated for the DNA extraction protocol of van Soolingen, et al. 2002 by determining M. tuberculosis viability at each process stage. Eight hundred eighty cultures were grown from 220 M. tuberculosis clinical isolates that had been processed through the first three DNA extraction stages. Molecular identifications of positive cultures used a PCR isolation of a fragment of the heat shock protein PRA-hsp65 and examination of its restriction enzyme profile (spoligotyping). Growth was seen in one culture with one of the procedures used. The molecular characterization did not correspond to the initially analyzed isolate, and therefore was deduced to be the product of a cross-contamination. The DNA extraction protocol, as described by van Soolingen, et al. 2002 and as implemented at the Instituto Nacional de Salud, was established to be safe for laboratory personnel as well as for the environment.

    We present incidence of primary cardiac tumors diagnosed from 1987 at the Hospital de Cardiología, Centro Médico Nacional Siglo XXI, in Mexico City. We described primary cardiac tumors based on histopathologic diagnosis, frequency, localization, implantation, implantation site, and recurrence. A total of 51 patient files were selected retrospectively. Patients underwent cardiothoracic surgery with primary cardiac tumor established by clinical and echocardiographic parameters with histopathologic corroboration between 1987 and 2002. Statistical analysis of obtained results show frequency, central tendency and standard deviation. Primary cardiac tumors were benign in 84% and malignant in 16%. Among benign tumors, myxoma was present in 74%, (38 cases) followed by papillary fibroelastoma in 6% (three cases); finally, there were two cases (4%) of fibroma. Malignant tumors belonged to two hemangioendothelioma cases (4%) and there were 6 cases of sarcoma (12%). Main affected gender was female in 61%. All cases were taken to surgical resection. There was recurrence four times (8%) belonging to three myxomas and one sarcoma. Average presentation age was 43 +/- 17 years. Cardiac primary tumors represent 0.16% of surgeries taking place at our service. Concordance was found with previous studies regarding frequency, gender, age, localization, and implant site of cardiac primary tumors with greater recurrence in our series.

    To describe the characteristics of non-alcoholic steatohepatitis (NASH) at the Instituto Nacional de la Nutricion Salvador Zubiran. We reviewed all liver biopsy reports from January 1982 to December 1991. From patient records we obtained the following data: clinical, biochemical, imaging studies and we reviewed the histological material. We correlated clinical, biochemical and histological data. From 2963 biopsies reviewed we obtained 16 cases of NASH. We found a 7:1 female/male ratio. Median age was 30 years and six patients were obese. Eleven patients had concomitant disease (diabetes in seven) and nine were using drugs. All had been studied for biochemical abnormalities and were asymptomatic. Ten patients had hepatomegaly and six splenomegaly. Ultrasound suggested the diagnosis in 50% of the cases. All had steatosis, inflammatory infiltrate, necrosis, fibrosis and Mallory bodies at different stages. One case had cirrhosis on initial biopsy and two developed cirrhosis on follow-up (one and eight years later). We did not find any correlation between clinical, biochemical or imaging characteristics and histological findings. When we compared these findings between obese and non obese patients and primary and secondary NASH we did not find any differences between groups. NASH is infrequent in our institution. The underlying pathogenesis seems to be multifactorial. There is no biochemical-histological correlation. Cirrhosis can develop in some cases.

    This paper deals with xenarthrans osteoderms assigned to Dasypus aff. D. novemcinctus, Euphractus sexcinctus and Cabassous sp. The material was collected in subsurface, from 0.10 to 0.60 m in the Urso Fóssil Cave, Parque Nacional de Ubajara, State of Ceará, northeastern Brazil. The ages of sediment samples from levels 4 and 5 (depths of 0.40 and 0.50 m) were determined by thermoluminescence technique, and indicated ages of 8,000 and 8,200 years BP for each layer respectively. The presence in these layers of early Holocene xenarthrans taxa can contribute to the understanding of the biotic evolution of the northwest region of Ceará during the last 10,000 years. Two of the three identified taxa still occur in the region: Dasypus novemcinctus and Euphractus sexcinctus. The Dasypodidae fauna here reported includes animals with generalist feeding habits and current wide geographical distribution. It is suggested, therefore, that the climatic and environmental conditions in the early Holocene were very similar the actual ones, and that the absence of Cabassous may be conditioned to other factors, such as anthropogenic action and loss of habitat by fragmentation of the vegetation.

    To determine the changes in the levels of dissatisfaction of the external users of the Instituto Nacional de Salud del Niño, in Lima, Peru. Observational study based on a software to evaluate surveys completed by health care users (Software de Evaluación de Encuestas de Usuarios en Salud - SEEUS). The population consisted of every person accompanying external users to outpatient visits, inpatient visits or emergency treatment in the years 2008, 2009 and 2010. To calculate the sample size, last year's proportion of users dissatisfied with each service was used, with an estimated error of 5% at a 95% confidence level. A sample of 2051 people was obtained, which revealed a decreasing trend in the levels of dissatisfaction with outpatient visits, and an increased dissatisfaction in the medical capabilities dimension for hospitalization and emergency services. In addition, a dissatisfaction index lower than 0.20 was registered in the medical capabilities dimension for outpatient visits. In contrast, the highest dissatisfaction indexes were registered in the hygiene dimension for 2009 (0.25) and 2010 (0.25), and in the others dimension for emergency services in 2009 (0.25). The dimensions showing an increase in the dissatisfaction index were tangible aspects, hygiene and others for hospitalization and emergency services. On the other hand, the medical capabilities dimension for outpatient visits showed a decrease in the level of dissatisfaction over the evaluated period.

    The spectral classifiers allow a good estimate for the mapping of the materials from the similarity between the reference curve and the image. Initially the spectral classifiers had been developed for hyperspectral images analysis. However, some works demonstrate good results for the application of these techniques in multispectral images. The present work aims to evaluate the spectral classifier Spectral Identification Method (SIM) in ASTER image. The Spectral Identification Method (SIM) is proposed to establish a new similarity index and three estimates according to the significance of regression (5%, 10% and 15%) of the materials. This method is based on two statistical procedures: ANOVA and Spectral Correlation Mapper (SCM) coefficient. This information can be used to evaluate the degree of correlation among the materials in analysis. The advantage of this method is to validate according to significance of regression most probable areas of the sought material. The method was applied to ASTER image at the Parque Nacional (DF - Brazil). The images were acquired with atmosphere correction. The pixels size from the SWIR image was duplicated in order to join the VNIR and SWIR images. Endmembers were detected in three steps: a) spectral reduction by the Minimum Noise Fraction (MNF), b) spatial reduction by the Pixel Purity Index (PPI) and c) manual identification of the endmembers using the N-dimensional visualizer. The classification was made from the endmembers of nonphotosynthetic vegetation (NPV), photosynthetic vegetation (PV) and soil. These procedures allowed identifying the main scenarios in the study area.

    This work presents the development and construction of the Heliometer of the Observatório Nacional/MCTI. This instrument is designed to monitor changes on the solar diameter with the accuracy of the next-generation solar satellites. A review of the heliometric method is made and the building and testing of 4 prototypes is described. The instrument has a mirror objective split in dihedral, formed by the hemi-sections of a parabolic mirror. The materials that form the instrument have thermal and mechanical stability to 10^(-7). The number of optical parts is minimized and their quality is greater than {λ}/12. An original software for the automated collection and analysis of the images was developed. With its latest version fully developed, we conducted an observational campaign of 9 days, deriving more than 70000 heliometric images of the Sun. The measured solar diameter has a standard deviation of 0.5 arcseconds, with no instrumental bias, and limited only by the provisional atmospheric modeling. Therefore, by improving the statistics, an accuracy at milliarcseconds can be achieved. A study of the correlation between the solar diameter and the geomagnetic field intensity was made. A correspondence between the peaks of the series related to solar activity, namely, the semidiameter variation, the flares index, and the sunspots counts, and the number of negative peaks on the intensity of the geomagnetic field is found. It must be cautioned though that it is a complex correspondence, requiring different modes of response and phase dependence on the stage of the cycle of solar activity. The straightforward interpretation of observational evidence indicates that the semidiameter of the Sun seems to vary significantly prior to the corresponding variations of the geomagnetic field. The effect is most evident in the downward phase of the solar cycle.

    The hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PPHN) are distinct pulmonary vascular complications of portal hypertension (PHT) and are associated with increased morbidity and mortality. To describe the clinical and laboratory characteristics of patients with pulmonary hypertension and pulmonary vascular complications hospitalized at the Instituto Nacional de Salud del Niño. We included patients with HTP hospitalized from January 2012 to June 2013 and that during its evolution progressed with SHP or HTPP. For analysis, they were divided into a first group of patients with liver cirrhosis and a second group with extrahepatic portal vein obstruction. Of 22 patients with HPT 45.5% were male and the age range was between 1 month and 17 years. The etiology in the group of cirrhosis (n=14) was: autoimmune hepatitis (35.7%), cryptogenic cirrhosis (35.7%), inborn error of metabolism (14.3%), chronic viral hepatitis C (7.15%) virus and atresia extra-hepatic bile ducts (7.15%). Pulmonary vascular complications more frequently occurred in patients with liver cirrhosis (1 case of HPS and a case of PPHTN). They most often dyspnea, asthenia, edema, malnutrition, ascites, hypersplenism and gastrointestinal bleeding from esophageal varices was found. Also, they had elevated ALT values, alkaline phosphatase and serum albumin values decreased. In children with pulmonary hypertension, pulmonary vascular complications are rare. In the evaluation of these patients pulse oximetry should be included to detect hypoxemia and ubsequently a Doppler echocardiography and contrast echocardiography necessary. Dueto the finding of systolic pulmonary hypertension it is necessary to perform right heart catheterization.

    Malignant tumors of the small bowel are uncommon and include multiple histologic strains, which helps explain the existing limited understanding of them. The aim of this study was to evaluate surgically treated small bowel tumors and to determine the clinical and pathological characteristics that can have an impact on patient outcome. A retrospective, observational, and descriptive study was carried out. The case records of patients with small bowel tumor that were surgically treated at the Instituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubirán" from 1990 to August 2011 were analyzed using the SPSS version 17.0 statistical package. Thirty-eight small bowel tumor patients were found that had been operated on within the time frame studied. Fifteen of them were women (39.50%) and 23 were men (60.50%), and the mean age was 55.6 years. The histologic distribution was 13 adenocarcinomas (34.20%), 10 neuroendocrine tumors (26.30%), 8 sarcomas (21.10%) and 4 lymphomas (10.50%). There was an increase in the incidence of sarcomas and adenocarcinomas, whereas lymphomas and neuroendocrine tumors were evenly distributed. An increase in small bowel tumor incidence in the last few years was observed and adenocarcinoma was the most frequent tumor in the study population. It is important to have a high degree of suspicion for this disease when patients present with symptoms such as gastrointestinal bleeding, bowel obstruction, anemia, and weight loss, because early diagnosis is essential for guaranteeing favorable outcome.

    About 250-300 children with newly diagnosed cancer are treated each year at the Unidad Nacional de Oncologia Pediatrica in Guatemala City; less than 5% of them have soft tissue sarcomas (STS). The aim of the article was to evaluate whether the therapeutic standards achieved in STS in developed countries could be reproduced in a low-income country. We reviewed the clinical data, treatment and outcome of 80 patients, 47 cases of rhabdomyosarcoma (RMS) and 33 of non-rhabdomyosarcoma soft tissue sarcoma (NRSTS), treated between January 2000 and October 2007. Most of the RMS patients had advanced disease at diagnosis (87% groups III-IV). Their 3-year event-free survival rate (EFS) was 26.4% if abandoning the treatment was considered as an event, or 32.4% if it was censored (14 patients abandoned the treatment), and the 3-year overall survival rate (OS) was 43.5%. Local progression/relapse was the main cause of treatment failure. Among the patients with NRSTS, the EFS at 3 years was 36.4% (when abandoning the treatment was considered as an event) or 43.3% (when it was censored), and the OS was 44.2%. Outcome was satisfactory for synovial sarcoma patients, those with tumors < or =5 cm, and those with localized disease. Overall results were unsatisfactory compared to results reported from developed countries. Late diagnosis and the consequently high proportion of cases of advanced disease at diagnosis, the large number of patients failing to complete the treatment, and the poor quality of local control (in RMS) adversely influence outcome.

    The methods used for the study of the small bowel are not ideal. Double-balloon enteroscopy is a new alternative with therapeutic potential. Evaluate the utility, efficacy and safety of double-balloon enteroscopy in Mexico. Adult patients seen in the Hospital de Especialidades Centro Médico Nacional Siglo XXI, Mexico City who were being studied for: chronic diarrhea, obscure gastrointestinal hemorrhage, weight-loss and chronic anemia were included in the study. Anterograde (oral) and retrograde (anal) approaches were used and study time, findings and complications were evaluated. Thirty-one enteroscopies were performed, 15 were anterograde, 8 retrograde and 8 were performed via both routes, in 23 patients studied between February and October, 2004; 10 of them were women and 13 men with ages ranging from 25 to 80 years. Fourteen patients were sedated and 9 patients were anesthetized. Study time varied form 55 to 90 minutes. With the anterograde route the ileum was reached in 56.6% of cases, 39.1% the jejunum and only in one patient (4.3%) the whole intestine was explored. With the retrograde route in 62.5% of cases the jejunum was explored and 37.5% the ileum. Four patients with obscure gastrointestinal bleeding and 1 patient with chronic anemia had vascular ecstasies, and in 40% of patients there was no identifiable cause. In 2 patients with intestinal stenosis biopsies revealed intestinal lymphoma in one and ischemic injury in another one. The adverse effects were mild and transitoru. Double-balloon enteroscopy is a safe diagnostic and therapeutic method that is useful in cases of obscure hemorrhage, chronic anemia; small bowel pathology was found in 64.7% of cases.

    The second most common mode of Trypanosoma cruzi or Chagas disease transmission is via therapeutic blood transfusion. In Mexico, control of T. cruzi is still in its initial phase; in fact, there are only 14 studies published covering 10 states on T. cruzi seroprevalence in donated blood in Mexico. Here we present the results of 5 years of trypanosomiasis screening in the blood bank of the Instituto Nacional de Pediatría. Samples from all blood donated in the period from 2004 to 2009 were analyzed. We screened for T. cruzi using an enzyme-linked immunosorbent assay technique. Seropositive samples were then processed using the polymerase chain reaction (PCR) to detect a nuclear gene segment. A total of 37,333 samples were analyzed and a 0.17% (64 samples) T. cruzi seroprevalence was found. Donors were mostly from Mexico State and Mexico City, which is considered nonendemic for T. cruzi area. Of 64 seropositive samples, only two tested positive by PCR (3.12%), which amplified a 189-bp product from nuclear gene from the parasite. Although the seroprevalence of T. cruzi infection was low, this surveillance program prevented the infection of more than 100 children because each unit of blood provides 2.6 to 3.5 blood products. The majority of the donors were from Mexico State and Mexico City, which is a nonendemic area. The serodetection of T. cruzi in this region is evidence that is necessary to increase our understanding of its distribution in the Mexico City and surrounding places. © 2011 American Association of Blood Banks.

    O período republicano até 1930 foi marcante na história do Observatório Nacional. Diversas reformas levaram a instituição a três ministérios diferentes e mudaram a ênfase do seu trabalho. A tão aguardada mudança para uma nova sede, em São Cristóvão, em 1920, não foi suficiente para que a instituição acompanhasse o ritmo tomado pela astronomia no mundo e se firmasse como ambiente de pesquisa. Uma análise simplificada poderia caracterizar um período de produção científica insignificante, dado o distanciamento da instituição dos novos rumos da astrofísica e da rápida inovação dos instrumentos, além do pequeno volume de publicações. Era uma época em que ainda não existiam os mecanismos formais de apoio e avaliação da atividade científica. Esse trabalho procura identificar a real atividade do Observatório no conteúdo dos Relatórios Ministeriais que, ao final de cada ano, apresentava as atividades, sucessos e problemas enfrentados pela instituição. Questões como instrumental e recursos humanos necessários; entraves burocráticos e financeiros; e articulações com outros observatórios se complementaram entre si ao longo desses anos para definir o perfil institucional e alguns aspectos fundamentais para a construção da astronomia no país. É possível concluir que a ênfase em serviços geográficos e de meteorologia, ao lado da inadequação dos instrumentos e do local, quase fizeram desaparecer a pesquisa em astronomia. Porém, vale destacar a sobrevivência de alguns trabalhos, como, por exemplo, variação de latitude e observação de estrelas duplas que mantiveram importante intercâmbio com outros grupos de pesquisa, demonstrando o constante esforço dos astrônomos e das diretorias em defesa da atividade científica.

    Prehepatic portal hypertension in children can be asymptomatic for many years. Once diagnosed, the therapeutic measures (pharmacologic, endoscopic, and surgical) are conditioned by the specific characteristics of each patient. In Mexico, there are no recorded data on the incidence of the disease and patient characteristics. To determine the main clinical, radiologic, and endoscopic characteristics upon diagnosis of these patients at the Instituto Nacional de Pediatría within the time frame of January 2001 and December 2011. A cross-sectional, retrolective, descriptive, and observational study was conducted in which all the medical records of the patients with portal hypertension diagnosis were reviewed. There was a greater prevalence of prehepatic etiology (32/52) (61.5%) in the portal hypertension cases reviewed. Males (62.5%) predominated and 11 of the 32 patients were under 4 years of age. The primary reason for medical consultation was upper digestive tract bleeding with anemia (71.9%) and the main pathology was cavernomatous degeneration of the portal vein (65.6%). Splenoportography was carried out on 17 of the 32 patients. A total of 65.5% of the patients received the combination therapy of propranolol and a proton pump inhibitor. Initial endoscopy revealed esophageal varices in 96.9% of the patients, 12 of whom presented with gastroesophageal varices. Congestive gastropathy was found in 75% of the patients. The varices were ligated in 8 cases, sclerotherapy for esophageal varices was carried out in 5 cases (15.6%), and sclerotherapy for gastric varices was performed in 2 patients. Seventeen patients (53.1%) underwent portosystemic diversion: 10 of the procedures employed a mesocaval shunt and 7 a splenorenal shunt. Nine patients (28.1%) underwent total splenectomy. The primary cause of the disease was cavernomatous degeneration of the portal vein; it was predominant in males and the first symptom was variceal bleeding. Copyright © 2014 Asociación Mexicana

    Since the founding of the Observatorio Astronomico Nacional de Chapultepec in 1878 during the presidential term of General Porfirio Diaz, begins the publication of the Yearbook of the Observatorio Astronomico Nacional de Chapultepec (from now on OAN) in a period when the positivist paradigm based on will boost science as a means of national progress. Here we describe the actions taken by the observatory's director and editor of the publication, the engineer Angel Anguiano, to initiate and successfully carry out the exchange of scientific publications and / or dissemination through the exchange of the Yearbook of the OAN, both nationally and internationally. The importance of conferences to which he attended started the sharing printed information relating to subjects such as astronomy, meteorology, cartography and geography. The Yearbook was intended to publish two or three months before the beginning of each year and according to the editor would serve to popularize science, making its contents available to anyone with basic knowledge of geometry or for amateur astronomers. I find that the yearbook was the publication that was released to the observatory in the country and abroad, but was sent to distant places where no one speaks or reads Spanish. I think that the content of articles published in, did not respond and objective and informative to the public as mentioned by, because at the late 1800s, 90% of the inhabitants of the Mexican Republic were illiterate and lived in rural areas. The access to the Bulletin was the Mexican intellectual elite grouped into societies, astronomical or meteorological observatories and another wealthy person individually. The same happened abroad. The collection of data from reports to the Secretaria de Fomento, that was the government agency that funds money destined to different scientific institutions founded during this period were published in the Yearbook, the oficios that sent the OAN over a hundred sites in the world

    Since April 2009, air samples are being taken bi-weekly at 10 GMT in the plain of the Estany Llong at 2100 masl. Estany Llong air sampling site (ELL, 42°34'29''N 0°57'17''E) is a remote site situated in the SW principal valley of the Parc Nacional d'Aigüestortes i Estany de Sant Maurici. New Flask-sampling equipment for Remote Mountain Sites was developed by the Institut Català de Ciències del Clima (IC3) to allow flask sampling in extreme weather conditions and carrying the sampling equipment for more than 10 km without damaging flasks. Dry Air analysis for CO2 are done at the Laboratory of IC3 using two coupled modified IRGA Licor-7000, where both pressure and flow are externally controlled. Far away from populated areas, ELL site acts as a remote site, but it is also responding to discrete events as snow melting, summer cattle breeding on pastures and trekking frequentation. Series of CO2 obtained are included as part of Long Term Ecological Research (LTER) at the Parc Nacional d'Aigüestortes i Estany de Sant Maurici. In the long term, these measurements show the mountain ecosystems contribution and geomorphologic influence on the CO2 budget of the air masses crossing a mountain range.

    A program of geologic mapping and mineral investigation in Colombia was undertaken cooperatively by the Colombian Instituto Nacional de Investigaciones Geologico-Mineras (formerly known as the Inventario Minero Nacional), and the U. S. Geological Survey; by the Government of Colombia and the Agency for International Development, U. S. Department of State. The purpose was to study, and evaluate mineral resources (excluding of petroleum, coal, emeralds, and alluvial gold) of four selected areas, designated Zones I to IV, that total about 70,000 km2. The work in Zone III, in the Cordillera Oriental, was done from 1965 to 1968. The northeast trend of the Cordillera Oriental of Colombia swings abruptly to north-northwest in the area of this report, and divides around the southern end of the Maracaibo Basin. This section of the Cordillera Oriental is referred to as the Santander Massif. Radiometric age determinations indicate that the oldest rocks of the Santander massif are Precambrian and include high-grade gneiss, schist, and migmatite of the Bucaramanga Formation. These rocks were probably part of the Precambrian Guayana Shield. Low- to medium-grade metamorphic rocks of late Precambrian to Ordovician age .include phyllite, schist, metasiltstone, metasandstone, and marble of the Silgara Formation, a geosynclinal series of considerable extent in the Cordillera Oriental and possibly the Cordillera de Merida of Venezuela. Orthogneiss ranging from granite to tonalite is widely distributed in the high- and medium-grade metamorphic rocks of the central core of the massif and probably represents rocks of two ages, Precambrian and Ordovician to Early Devonian. Younger orthogneiss and the Silgara are overlain by Middle Devonian beds of the Floresta Formation which show a generally low but varying degree of metamorphism. Phyllite and argillite are common, and infrequent marble and other calcareous beds are fossiliferous. Except for recrystallization in limestones of !the

All discharged patients between 1997-2007 with AMI diagnosis according to International Statistical Classification of Disease 10th Revision codes I 21 - I 21.9 were included. Information about age, sex, marital status, socioeconomic level, occupation and current address were obtained from the patient's file. The findings were compared with a previous published paper from 1954-64. The number of AMI cases increased five times between both decades, and significant changes were observed in occupational activity and in the socioeconomic level. Some social and economic factors have changed over the years; however, age and gender of patients with AMI are variables that did not showed significant changes: most young patients are male, and women are older when they have a fist AMI.

    1973-01-01

    This report summarizes the geology of an area of some 6000 square kilometers in the northern part of the Central Cordillera of the Colombian Andes. The area, in north-central Department of Antioquia, was mapped between 1964 and 1968 as part of the Inventario Minero Nacional (IMN) project. Mineral resources are summarized within a larger area, designated as subzone ILK of IMN Zone If, which comprises almost 22,000 sq. kin, including the area mapped geologically by IMN and additional areas mapped by other agencies. The oldest formation is a micaceous paragneiss of early Paleozoic or possibly late Precambrian age. A thick geosynclinal sedimentary series accumulated during the Paleozoic Era and became regionally metamorphosed to greenschist (locally amphibolite) facies during the Permian or early Triassic; these schists and gneisses are designated collectively as the Valdivia Group. The Permian(?) orogenic episode included intrusion of concordant syntectonic plutons, mostly of tonalitic composition. Rocks of unequivocal Triassic or Jurassic age are not recognized. The Cretaceous is well represented by both igneous and sedimentary assemblages. Eugeosynclinal alpine ophiolites comprising submarine basalt flows and numerous intrusions of gabbro and serpentinite are prominent in the Lower Cretaceous, together with flysch composed of marine shale and lesser sandstone and conglomerate. The Upper Cretaceous is represented along the west border of the mapped area by submarine basalt flows and pyroclastic rocks, locally Interbedded with fine-grained clastic sedimentary beds, and lenses of dark laminated chert, at least part of which is radiolarian. The Late Cretaceous was marked by an orogenic event that profoundly folded and faulted all rocks and in the Central Cordillera caused low-grade metamorphism, the overprint of which is hardly observable in pre-Cretaceous rocks elsewhere. The Late Cretaceous orogeny culminated with discordant intrusion of the epizonal tonalitic

    Inflammatory fibroid polyp (lFP) is a rare, benign, and solitary neoplasm predominantly located in the gastric antrum and small bowel. Its clinical symptoms are heterogeneous and essentially depend on the location and size of the tumor. Definitive diagnosis is made through histopathology and this pathology has excellent long-term prognosis. To identify the cases of IFP seen at the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán over a 10-year period. A retrospective, cross-sectional, descriptive, and observational study was conducted that included patients with histopathologic diagnosis of IFP within the time frame of January 2001 and December 2011. Six cases were found and 5/6 (83.3%) of them were women. The median age was 41 years (minimum-maximum range of 19-56 years). The most frequent symptoms were weight loss (n=3), fever (n=2), nausea (n=2), and vomiting (n=2). Three patients presented with iron deficiency anemia and 2 cases with intussusception. The IFPs were located at the following sites: esophagus (n=1), stomach (n=2), small bowel (n=2), and colon (n=1). Treatment was surgical in 5/6 (83.3%) of the patients. IFPs are extremely rare in our population. They usually present with weight loss and iron deficiency anemia and are more frequently located in the stomach and small bowel. This is the largest reported IFP case series in a Mexican population. Copyright © 2016 Asociación Mexicana de Gastroenterología. Publicado por Masson Doyma México S.A. All rights reserved.

    The performance of the 1 MV AMS system at the CNA (Centro Nacional de Aceleradores, Seville, Spain) for 236U and 239,240Pu measurements has been extensively investigated. A very promising 236U/238U abundance sensitivity of about 3 × 10-11 has been recently achieved, and background figures for 239Pu of about 106 atoms were reported in the past. These promising results lead to the use of conventional low energy AMS systems for the analysis of 236U and 239Pu and its further application in environmental studies. First 236U results obtained on our AMS system for marine samples (sediments and water) are presented here. Results of two new IAEA reference materials (IAEA-410 and IAEA-412, marine sediments from Pacific Ocean) are reported. The obtained 236U/239Pu atom ratios, of 0.12 and 0.022, respectively, show a dependency with the contamination source (i.e. local fallout from the US tests performed at the Bikini Atoll and general fallout). The results obtained for a third IAEA reference material (IAEA-381, seawater from the Irish Sea), are also presented. In the following, the uranium and plutonium isotopic compositions obtained on a set of 5 intercomparison seawater samples from the Arctic Ocean provided by the ETH Zürich are discussed. By comparing them with the obtained results on the 600 kV AMS facility Tandy at the ETH Zürich, we demonstrate the solidity of the CNA technique for 236U/238U determinations at, at least, 7 × 10-10 level. Finally, these results are discussed in their environmental context.

    The best revascularization method of the unprotected left main is a current and evolving topic. Within 3 years, 2439 percutaneous coronary interventions (PCI) were registered. We included all the patients with PCI of the unprotected left main, n=48 and matched with patients who underwent coronary artery bypass graft (CABG), n=50. Mayor adverse cerebral-cardiac events (MACCE) were assessed in-hospital and out-hospital during a 16 months follow up. PCI showed higher risk profile that CABG group; logEuroSCORE 16±21 vs. 5±6, p=0.001; clinical Syntax 77±74 vs 53±39, p=0.04. In-hospital MACCE (14% vs 18%, p= 0.64) were similar. The post-procedure ST myocardial infarction was less frequent in with PCI (0 vs 10%), p=0.03. The PCI group showed less MACCE (2.3% vs 18%, p=0.01) and a favorable trend in death (2.3% vs 12%, p=0.08) and cardiac death (2.3% vs. 8%, p=0.24) when patients presenting with cardiogenic shock were excluded. MACCE were comparable between PCI and CABG groups; (15 vs 12%, p=0.46) in the out-hospital phase. Survival without MACCE, death or cardiac death were comparable between groups (log rank, p=0.38, p=0.44 y p=0.16). Even though the clinical and peri-procedural risk profile of the PCI patients were higher, the in-hospital and out-hospital efficacy and safety were comparable with CABG.

    A medical compendium of 'Melleus liquor physicae artis' has survived under the name Alexander Hispanus, possibly a medical scholar of the 13th or early 14th century, in codex Ms 8769 of the Biblioteca nacional in Madrid. But we don't know verifiable facts about Alexander Hispanus. There are more indications, that Alexander was a fictitious person and he never lived. The compendium tells about the maintaining of health as a matter of concern with strong temporal regulations. Therefore a bavarian tract about critical days was enclosed afterwards. This is very interesting, because the tract is dated to 1350 and it's written by a younger hand. Compared with that other parts of the handwriting are dated roughly to the 14th century and are written by an older hand. This tract was now edited (look to the appendix). At the same time a structural analysis of the organisation of knowledge clarified, that the Melleus liquor must be sawn as a well thought-out text altogether. The parts are connected within of three levels of structure: human, medicine, deseases and their recognition. But time is of overriding importance and it's superordinated to these factors of structure. All in all the handwriting monument is certainly written in the 14th century, but it documents medical doctrines of an older age. The late medieval writer probably used much older scripts, that don't exsist any longer. But so they were copied and came down to us fortunately.

  1. Minero-chemical composition as environmental quality assessment tool of an artificial water reservoir: the case of the "Pietra del Pertusillo" lake (Basilicata, Italia)

    The Pietra del Pertusillo fresh-water reservoir is an artificial lake located in the High Agri River Valley (Basilicata); its dam was completed in 1963 for producing hydroelectric energy and providing water for human use to Puglia and Basilicata southern Italian regions (approximately 2 million people). Pertusillo lake lies within a national park because of the presence of many special protected areas. This reservoir is a natural laboratory for assessing the sediment pollution from human activities, including: waste-water treatment plants, landfills, farms, treatment oil plant, plastics and other industrial activities. In addition, the Pertusillo reservoir is located in the area of the largest oil field of continental Europe. This anthropogenic pressure may thus represent an impact factor on the environmental equilibrium and consequently the knowledge and control on their quality represents a relevant environmental challenge. This study reports the preliminary results of a multidisciplinary (sedimentological, mineralogical, geochemical) PhD research focused on the analysis of the lacustrine sediments filling the Pietra del Pertusillo fresh-water reservoir. The lakes and its sediments represent the natural sink for nutrients and possible pollutants which tend to accumulate in relation to the nature and composition of the solid matrix but also the concentration and characteristics of the substances themselves. Moreover the deeper sediments, deposited under undisturbed condition, represent the "historical memory" of the ecosystem. Sub-aqueous lake sediments were investigated in May 2014, sampled using a small platform and a gravity corer (UWITEC, Austria) of 90 mm diameter which allowed to drill 19 cores up to 2 m long from the sediment/water interface. Successively cores were studied and described by using facies analysis techniques; a large number of core samples (147) were collected from the working half of each core, stored in HPDE containers, and frozen at -20°C for subsequent chemical and mineralogical analysis. Further, in order to assess the provenance effects on the composition of lake sediments, the bedrock (Meso-Cenozoic rocks and Quaternary fluvial-lacustrine deposits) and the stream sediments of the main "Pietra del Pertusillo" tributaries, close to the detrital supply entry points of Pietra del Pertusillo lake were also sampled. The mineralogical composition was obtained from randomly oriented powders by XRPD. Chemistry (major, minor, and trace elements) was performed on powdered samples by ICP-MS technique after a four acids digestion and lithium metaborate/tetraborate fusion to facilitate the destruction of possible resistate minerals. Preliminary data related to the stream sediments show that both major and minor elements (including heavy metals, barium and arsenic) have a minor variability and are close to the median values of the bedrock. The mineralogical composition of the analysed samples can explain the elemental relationships,thus excluding any anthropogenic input. The mineralogical composition of the lacustrine samples is made of quartz, carbonates, feldspars, muscovite/illite, chlorite, and interstratified clay minerals, and it is constant throughout the cores. Finally, as further step ot he research plan, we are processing 20 of all lake samples with the highest peaks of interstratified clay minerals, which likely represent the most reactive phases in our sediment-water system.

    The association between cytomegalovirus and ulcerative colitis has been reported by many authors, but the exact pathogenesis of this relationship remains unclear. We reviewed all ulcerative colitis cases whose diagnosis were made in Hospital dos de Mayo, during period 2000-2005, these cases were evaluated for Cytomegalovirus using inmunohistochemistry, also we described histological features of our cases. CMV was identified in 22.2% of all cases, none of them had been treated with inmunosuppressants previously, histological activity was reported in all positive cases and 42.8% negative cases for CMV; Crypt architectural abnormality was the most often histological finding, and the frequency of ulcerative colitis was 1.5 per year. Our findings are similar to those reported by foreign authors and is consistent with theory which maintains inflammatory changes of UC would help CMV's activation without using inmunosuppressants.

    Peru's National Population Council is currently developing a national program of population communication. The program will be coordinated with public and private sector activities and will seek help from international organizations. The objective of the program is to promote changes in population knowledge, attitudes, and behaviors in priority social sectors and general public opinion to achieve a better harmony between population growth and distribution and socioeconomic development. The program strategy is to begin with identification of priority audiences. Other components of the strategy include quality control, coordination, decentralization, participation, use of low-cost technologies with high impact, and a multidisciplinary focus. An inventory of institutional activities in population communication will be a major activity.

    An analytic prospective study was done in cirrhotic patients with Portal hypertension to study a new pathology known as Portal Hypertensive Gastropathy. In 73.3 per cent of patients with cirrhosis, hospitalized inthe Gastroenterology Area, Portal Hypertensive Gastropathy was present. Males in the 4th decade of their life were predominant. Mild gastropathy with a mosaic or snake skin endoscopy pattern was the most frequent (60.6%), while in severe gastropathy, the most common pattern was cherry red spots. These lesions were often located in the stomach fundus and body. All the patients presented some vascular alteration and lymphoplasmocytic inflammatory infiltration. No relation was found between the severity of Portal Hypertension or Advanced Liver Disease and changes of the gastric mucosa.

    Four expeditions were made to Coiba National Park between 1996 and 1998 to characterize this part of the poorly known Panamian Pacific polychaete fauna. The samples were collected by SCUBA diving, either by removing 4 kg blocks of dead coral (Pocillopora sp.) or scraping off 25 x 25 cm quadrats of Telesto multiflora or algae (Dyctiota cf. flavellata, Padina cf. durvillaei and another currently unidentified species). This paper deals with the Syllinae from hard substrates. Twenty-two species belonging to six genera of the subfamily Syllinae Grube, 1850 (Syllidae: Polychaeta) are reported. A new species, Syllis castroviejoi, is described. Four species are newly reported for the Eastern Pacific: Syllis beneliahuae (Campoy & Alquézar, 1982), S. botosaneanui (Hartmann-Schröder, 1973), S. corallicola Verrill, 1900 and S. garciai (Campoy, 1982), and, likewise, two species are first reports for the Central American Pacific coast: Branchiosyllis pacifica Rioja, 1941 and Syllis truncata Haswell, 1920. Two species, Syllis magna (Westheide, 1974) and S. pigmentata (Chamberlin, 1919), are newly reported for Panama.

    The Inventario Minero National (IMN), a four-year cooperative geologic mapping and mineral resources appraisal project, was accomplished under an agreement between the Republic of Colombia and the U. S. Agency for International Development from 1964 through 1969. Subzone IIB, consisting essentially of the east half of Zone comprises nearly 20,000 km2 principally in the Department of Antioquia but including also small parts of the Departments of Caldas and Tolima. The rocks in IIB range from Precambrian to Holocene. Precambrian feldspar-quartz gneiss occupies a mosaic of fault-bounded blocks intruded by igneous rocks between the Oto fault and the Rio Magdalena. Paleozoic rocks are extensive, and include lightly metamorphosed graptolite-bearing Ordovician shale at Cristalina, and a major suite of graphitic quartz-mica schist, feldspathic and aluminous gneiss, quartzite, marble, amphibolite, and other rocks. Syntectonic intrusive gneiss included many of the older rocks during a late Paleozoic(?) orogeny, which was accompanied by Abukuma-type metamorphosing from lowermost greenschist to upper amphibolite facies. A Jurassic diorite pluton bounded by faults cuts volcanic rocks of unknown age east of the Otu fault. Cretaceous rocks are major units. Middle Cretaceous carbonaceous shale, sandstone, graywacke, conglomerate, and volcanic rocks are locally prominent. The Antioquian batholith (quartz diorite) of Late Cretaceous age cuts the middle Cretaceous and older rocks. A belt of Tertiary nonmarine clastic sedimentary rocks crops out along the Magdalena Valley. Patches of Tertiary alluvium are locally preserved in the mountains. Quaternary alluvium, much of it auriferous, is widespread in modern stream valleys. Structurally IIB constitutes part of a vast complex synclinorium intruded concordantly by syntectonic catazonal or mesozonal felsic plutons, and by the later epizonal post-tectonic Antioquian batholith. Previously unrecognized major wrench faults are outstanding

    Reynard (2004) defined a geomorphological landscape as a portion of the geomorphological context that is viewed, perceived, (and sometimes ex- ploited) by Man and, when perceived by humans and characterised by certain attributes, it may be considered a wider geomorphosite (Reynard and Panizza, 2005) or a complex of geomorphosites inside of which single geomorphosites can be individuated. Moreover, single geomorphosites belong to a landscape system that is dynamic, and thus the comprehension of a geomorphosite mechanism requires good observations, measurements and quantifications of processes (Reynard 2004). Since 1990s, interest on geomorphosite studies has increased, especially, due to their educational. The aim of this study is to present a preliminary inventory of the main geomorphosites that can be found along the Great Málaga Path (or Gran Senda de Málaga). This route, developed by the Government of Malaga Province, is a pioneer in Andalusia route incorporating the territorial and environmental range of an entire province, integrating it into a journey that stimulates interest in natural spaces. One of the main attractions is crossing most of the more important sites from the geomorphological point of view in the Province of Málaga. In this study, some of them are inventoried in order to highlight their importance and improve their knowledge from educational and touristic purposes. The methodology follows that proposed by the Spanish Geological and Mining Institute (IGME, 2014). References IGME, 2014.

    The geomorphological landscape, as it was defined by Reynard (2004) can be considered a portion of the geomorphological context that is viewed, perceived, (and sometimes ex- ploited) by Man and, when perceived by humans and characterised by certain attributes, it may be considered a wider geomorphosite (Reynard and Panizza, 2005) or a complex of geomorphosites inside of which single geomorphosites can be individuated.

Since 1990s, interest on geomorphosite studies has increased, especially, due to their educational. The aim of this study is to present a complete inventory of the main geomorphosites that can be found in the Province of Málaga, with educational purposes. The Province of Málaga, located in the South of Spain, in the Mediterranean Coast but very close to the Atlantic Ocean, is characterised by a wide range of geomorphological landscape, with many different landforms and very dynamic land uses. The methodology follows that proposed by the Spanish Geological and Mining Institute (IGME, 2014). In total, more than 100-geomorphosites were recognised, inventoried and classified in order to achieve a better comprehension and improve the learning of high academic level students.

    Objectives: The purpose of this study was to review the epidemiological aspects of displacement fractures of the acetabulum that had been treated surgically at the National Institute of Traumatology and Orthopedics (INTO). Methods: We retrospectively analyzed 126 acetabulum fractures that had been treated surgically at INTO between March 2006 and November 2008. The following factors were taken into account: age, sex, trauma mechanism, injury classification, time elapsed between trauma and surgery, affected side and associated bone injuries. Results: 76.8% were male; the mean age was 39.6 years. The trauma mechanism was traffic accidents in 59%; the time that elapsed between injury and surgery was on average 16.4 days; 55% of the cases were on the right side; 30% of the patients presented associated fractures. Conclusion: Most of the patients were male, in an economically active age group, and were victims of traffic accidents. Edge and/or posterior column fractures were the most frequent types. Associated injuries were common and most of the fractures operated in our service came to us late. PMID:27022597

    First let's describe the context. Approximately 80% of our students in Medellin major in engineering. In the National University system students can choose freely twenty percent of the credits. Their decisions are made taking into account various reasons. As far as we know the amount of work and the expected grades are factors besides the interest in the topics. Statistics show that there is an even distribution among complementary professional, cross-disciplinary and general interest courses. Plan B took the name from Lexter Brown book, which was the original inspiration and text. The program expanded with more in depth consideration to a general understanding of climate and climate change science, and to water and energy crises because they are close to my research area. But we consider other global change uses as well, including recycling, loss of biodiversity, food crises, economics of climate change and demographic and social issues. We developed a textbook whose title would translate as "Where is the Globe heading?" that refers to a usual saying during Christmas time in relation to candle balloons popular at that time of the year that children and teen-agers try to catch. The expression reflects the need for predictions, call for action, but also acknowledges that chance is a factor to consider. I believe it summarizes well the content of the course. The class meets in a large auditorium with 250 sits. We moved from the usual size room of about 50 because of the large demand during registration. This forced us to adjust the methodology, but our evaluation is that such a large audience is worthwhile. Student's feedbacks at the end of the semester confirm this with very good rating and general comments. Besides crude diagnostics of the problems based on data and science we always make an effort to present solutions. For instance there is ample consideration to renewal energy technologies. Globalization is also a theme of the course, there are local actions but in particular curbing of greenhouse gas emissions needs global actions. We need that this kind of efforts spread to many campuses around the world and need to share experiences to take advantage of globalization.

    Colorectal cancer (CRC) is the fourth most common cancer in the world and is classified according to their origin in sporadic CRC (~ 70%) and genetic CRC (~ 30%), this latter involves cases of familial aggregation and inherited síndromes that predispose to CRC. To describe inherited CRC predisposition syndromes, polyposic and non-polyposic, identified in the Oncogenetics Unit at National Institute of Cancer Disease (INEN). A descriptive observational record from the attentions of the Oncogenetics Unit at INEN during 2009 to 2013. We included patients with personal or familiar history of CRC and/or colonic polyposis who were referred for clinical assessment to the Oncogenetics Unitat INEN. 59.3 % were female, 40.7 % male, 69.8% under 50 years old, 60.5% had a single CRC, 23.2% had more than one CRC or CRC associated with other extracolonic neoplasia and 32.6% had a familiar history of cancer with autosomal dominant inheritance. According to the clinical genetic diagnosis, 93.1% of the included cases were inherited syndromes that predispose to CRC, with 33.8% of colonic polyposis syndromes, 23.3% of hereditary nonpolyposis CRC syndromes (HNPCC) and 36.0% of CCRHNP probable cases. Clinical genetic evaluation of patients with personal or familiar history of CRC and/or colonic polyposis can identify inherited colorectal cancer predisposition syndromes and provide an appropriategenetic counseling to patients and relatives at risk, establishing guidelines to follow-up and prevention strategies to prevent morbidity and mortality by cancer.

    Neotropical puma (Puma concolor) diet is scarcely known, in particular that of mountain dwelling individuals from Northern South America. This is the first study on pumas from the paramo and the first puma diet analysis for Colombia. The puma diet was studied from 2007 to 2009 in the Puracé National Park in the South Colombian Andes. Paramos are unique neotropical high altitude ecosystems which store and regulate water, and are currently threatened by agricultural expansion and climate change. Seven latrines were monitored for three years and scat collected, washed and dried. Items in scat such as hair, bones, claws and others were separated. Hairs were inspected by microscopy and compared to voucher hair museum specimens. Bone fragments, claws and teeth were also compared to museum collections and identified wherever possible. Additionally, six cameras were set along game trails to document puma and potential prey presence in the area. Food items from five species were identified in 60 puma scats; Northern Pudu (Pudu mephistophiles) was the most important prey in their diet. A total of 354 camera trap-nights photographed a male and female puma, Northern pudu and Spectacled bear (Tremarctos ornatus). The main conclusion suggests a strong dependence of puma on the threatened and mysterious Northern Pudu in paramo habitats. This behavior might reflect restricted prey availability in the high Andes mountains of Colombia, and highlights the plasticity in the puma diet. Conservation actions in the paramo should thus, focus on focal wild species, and in particularly those that show a relationship, such as the one evidenced here with the dependence of puma on Northern Pudu. These findings contribute to increase the little known ecology of Andean puma populations and the species as a whole in Colombia. Baseline data on puma prey populations in different ecosystems throughout their range, is critical to understand the regional requirements for survival, and design conservation actions, to follow and evaluate the need for particular protected areas along their geographical gradients.

    Thirty patients with Burkitt's lymphoma sporadic type are presented. All of these cases fulfilled the histologic criteria of Burkitt's tumor. The age ranged from 2 to 12 years, with a median of 4 years. Fever and chills were the most common symptoms. The abdomen was the site of initial presentation in more than half of these cases. Close to one-third of the patients had involvement of the central nervous system. Fifty percent of the patients presented with lactic dehydrogenase elevation. Uric acid was elevated in close to one-fourth of these patients. The sonogram was the most useful technique in those instances of abdominal presentation. All patients were staged according to Ziegler criteria after an initial surgical diagnostic procedure was performed. None of the patients received radiotherapy to the primary tumor. All were submitted to a chemotherapy program for 12 months. Only 26 fitted the criteria of being evaluable. The duration of remission was from 1 to 144 months, with a median of 18.2 months. The actuarial survival was 84% at 3 years. Most of the responders corresponded to Stages A, B, and AR, while Stages C and D had a high mortality rate with elevated lactic dehydrogenase and uric acid levels.

    Any population policy aimed at influencing population growth, or spacial distribution of population must take into consideration social policies, such as education and health, and also demographic policies, such as reduction of mortality. Such policy must be global in its outlook, and must plan for long term results. Economic and social development carries with it the almost irreversible phenomena of demographic transition and urbanization, and its implementation must never violate the fundamental rights and the dignity of the individual citizen. Designing a strategy to achieve certain demographic objectives implies the coordinated action of different sectorial policies, and a very precise knowledge of existing circumstances.

    The first renal transplant was done on July 22, 1968 and until December, 2010 a total of 865 procedures have been performed. Immunosuppressive protocols have changing with time: from 1968 to 1984 azathioprine + prednisone plus total radiation in some cases; from 1985 to 1998 cyclosporine + azathioprine + prednisone; in 1998 tacrolimus is used for first time; Mofetil micofenolate was available at 2005 and practically has displaced to azathioprine. As far as possible we use some induction therapy. Primary ESRD etiologies were: unknown (74.9%), glomerulonephritis (9.7%) and diabetic nephropathy (4.2%). Recipient's mean age was 29.9 +/- 11.6 years (12-70) and 35 +/- 9.8 years (18-62) in donors. Analysis group for graft and patient survival included 292 transplants (censured for death with functional graft) with a follow-up of 103 months (CI 95%: 99-108). Survival at 1, 5 and 10 years were: 95, 85 and 60% for graft as well as 100, 94 and 90% for patient. In year 2000 we started to perform renal biopsies at transplant (time zero biopsies), those results have been published and at present are a worldwide reference. In September, 2005 laparoscopic donor nephrectomy is initiated, 180 procedures have been done with excellent results. In year 2006, training in renal transplant acquires the endorsement as a Medicine Posgrade recognized by the UNAM School of Medicine. We have participated in 9 national clinical trials and 6 international multicentric ones. Our renal transplant program offers a good choice for patients with low resources with similar results reported in the literature using current immunosuppressive schemes and surgical procedures. Institutional authorities and humanitarian associations support in addition to participation on investigation studies have been of vital importance.

    Uterine sarcomas are a group of uncommon tumors that account for approximately 1% of malignant neoplasms of the female genital tract and between 3 and 8.4% of malignant uterine neoplasms. To evaluate the factors associated with the clinical behavior of uterine sarcomas. In the period from October 1983 to December 2009, clinical files of patients with a confirmed diagnosis of uterine sarcoma at the National Institute of Cancerology of Mexico (INCan) were reviewed and evaluated. We identified 77 cases with complete information; average age at presentation was 51.6 years (range, 14-78 years); most frequent histology was leiomyosarcoma (LMS) in 53/77 (68.8%) cases; most frequent symptom reported at the time of diagnosis was abnormal vaginal bleeding in 36/77 (46.7%) cases, and the most frequent clinical stage was clinical stage (CS) I in 31/77 (40.2%) cases. Initial treatment was total abdominal hysterectomy (TAH) and bilateral salpingo-oophrectomy (BSO) in 53/77 (68.9%) cases. Disease-free period was 27.8 months (range, 0-184 months), with disease recurrence in 33/77 (42.85%) cases, most frequent site as lung in 13/33 (39.39%) cases. Management of recurrences was surgery and chemotherapy (CT) in 5/33 (15.15%) and CT in 10/33 (30.30%) of cases. At present, 40.3% of the patients (31/77) are found to be Disease-free. Notwithstanding that uterine sarcomas are aggressive neoplasms, most accepted management to date is TAH + BSO, observing that the fact that this procedure is not performed by oncologists does not affect the DFP nor OS, contrary to what occurs in other gynecological neoplasms.

    In this paper the acoustic design of the separate buildings housing the school of music, school of drama, and school of dance that opened in 1996 will be described. Spaces that JHA designed included practice rooms, studios, rehearsal rooms, black box, and concert hall. Details of room acoustic treatments, sound isolation measures, and venturi air flow will be illustrated. An overview of the entire project will also include the 500 seat multipurpose theater (with variable absorption systems) and the Alla Magna. Differences between the American and Mexican styles of consulting, importing of materials, installation, and commissioning will also be discussed.

    SARA (Spanish Accelerator for Radionuclides Analysis) was the first multielemental AMS facility installed in Spain in 2005. Since then it has been dedicated to the routine analysis of several radionuclides, such as 10Be, 14C, 26Al, 129I and Pu isotopes. Tests have been carried out with other isotopes, such as 41Ca, 236U and 237Np, and several changes have been made to the original facility to improve performance. First, an upgraded version of the ion source SO-110 has allowed us more stable measurement conditions for volatile elements (i.e. iodine), and a better general performance. Besides, changes in the target geometry have improved the ionization efficiency and long-term stability of the source output. Moreover, different software upgrades have been introduced to meet our routine operational needs. Finally, changing the movable Faraday-cup associated electronics now allows the measurement of smaller currents (in the range of pA), which has been key for the study of 236U/238U atomic ratio in environmental samples. Apart from these modifications it has to be noted that routine radiocarbon measurements have been moved to a Micadas system (200 kV) installed at CNA in 2012. In this paper we will illustrate the evolution of the facility up to now, and our future prospects will be introduced.

    The essential role of the National Parks is to protect nature, in order to prevent the deterioration and loss of the ecosystem under protection. Very few records about the diversity of arthropods are known from Los Cardones National Park, where three eco-regions are protected: Puna and Monte eco-regions and the High Andean Grassland of the Yungas. Here, we aimed to compare the alpha and beta diversity of arthropods in these eco-regions, and to prove if sites from the same ecoregion, show greater similarity between them in their assemblages, than with sites of the other eco-regions. We also identified arthropod orders with higher species richness, and indicated the families that contribute the most to the registered beta diversity. Three sampling sites were established on each eco-region and the arthropods were sampled using pitfall traps and suction samples. We evaluated the obtained inventory through nonparametric estimators of species richness, and compared diversity among eco-regions through "diversity profiles" and "effective number of species". Beta diversity was assessed by different methods such as the Morisita Index, nonmetric multidimentional scaling analysis, a multiple permutation procedure, and a Similarity Percentage analysis. We recorded 469 spp/morphospecies and recognized three arthropod orders (spiders, dipterans and hymenopterans) that are diverse and abundant in the Park. Besides, the diversity in Los Cardones National Park was found to be high, but it was observed higher in the High Andean Grassland of the Yungas, and lower in the Puna. The inventory obtained was good, reached up to the 81% of the species richness estimated by nonparametric estimators. Each eco-region of the park showed a very particular arthropod community that was tested by a multi-response permutation procedure. The species turnover between eco-regions was high, so that the different environments of the protected area are contributing to the maintenance of the regional diversity of arthropods in the park. The assemblages of arthropods belonging to the same eco-region sites showed greater similarity among themselves than with those of more distant sites. This represents the first attempt for biodiversity studies in these areas, but more evaluations are required to detail on the possible climate change and human impacts in the ecosystem.

    The benthic fauna and diel variation in a shallow seagrass bed (Thalassia testudinum) were studied in Playa Mero, Venezuela. Samples of organisms and sediments were taken using PVC cylinders, 5cm in diameter, along a transect perpendicular to the coast. Seagrass cover, shoot density and biomass were estimated. The seagrass cover was homogeneous along the transect. The intermediate zone had the highest number of shoots and of above-ground and rhizome biomass. Composition and abundance of benthic organisms were related with seagrass and sediment characteristics. Sediment organic matter content and organism abundance were highest near the shore Molluscs, polychaetes, oligochaetes and nematodes were the most abundant groups. Species richness was higher in daytime (40 versus 28 at night). Gastropods were the most abundant organisms both at day and night while polychaetes and crustaceans increased during the day, and holoturids were more numerous at night.

    The coral reef fish community was studied in Playa Mero, Morrocoy National Park, after the mass mortality of January, 1996 with a systematic sampling design. Transects and quadrates were used for corals, and a visual census for fishes. The coral community is highly disturbed with extensive areas of dead coral covered by algae, and low coverage and richness of coral species, gorgonians, sponges and briozooans. These factors have generated a relatively homogeneous environment with respect to the fish community, which was dominated by Scaridae and Pomacentridae that represented 75% of fish. Dominant fishes were mainly herbivorous (75.4% of all fish) apparently because of the disturbance that caused the settling of algae.

    The year 1996 had a high pluviosity in Morrocoy National Park (western coastal zone, Venezuela) and low salinity in December 1996 affected the seagrass beds, dominated by Thalassia testudinum. Patches without T. testudinum were observed in localities of the park that used to have very dense populations of this plant. Sampling was done at Las Luisas to determine leaf productivity, turnover rate, short shoot density and relative biomass of plant sections, in order to compare with data obtained in September 1996, previous to the event. Green leaves, roots and rhizomes were the most affected parts. Mean green leaf biomass decreased in January and February 1997 to 5% of the plant's total biomass; mean root biomass decreased in March to 40% and mean rhi zome biomass decreased in February to 30%. The density of the active short shoots decreased to a minimum in February, but in April it reached a value similar to that of September 1996. The density of the inactive short shoots decreased to a minimum in March, and they dissappeared in April, matching the increasing density of the active short shoots between these two months. In February 1997, 56% of the inactive short shoots showed evidence of leaf initiation. In January 1997 the leaf productivity and turnover rate values (2.72 +/- 0.35 g/m2/d and 2.15% leaf DW/d) were similar to the annual mean previously determined from Las Luisas (2.35 +/- 0.72 g/m2/d and 1.96% leaf DW/d). Nevertheless, the values of productivity and turnover rate detected at Las Luisas in April 1997 (4.88 +/- 2.14 g/m2/d and 4.66% leaf DW/d) were higher than those values previously reported for this location. In response to the mortality episode, the leaf productivity and turnover rate of T. testudinum increased and the leaf initiation was activated in the inactive short shoots.

    Many columnar cacti are bat pollinated. It has been suggested that this kind of pollination would be more important in tropical than in temperate regions where flowers are open only one night. Thrichocereus pasacana produces big and resistant white flowers. We analyzed flower characteristics, floral cycle, stigmatic receptivity, nectar production, pollen presence and floral visitors in a T. pasacana population at National Park Los Cardones (Salta, Argentina) in November 1997. Flower features were constant between individuals of the population. Flowers start opening at evening and anthesis time is from 18 to 40 hs. The estigma was receptive throughout the floral cycle. Anther dehiscence occurs with flower opening. Nectar production was highest between 18 to 24 hs. Although T. pasacana are open during the night, floral visitors are diurnal. The most frequent was Xylocopa sp. In the study area, nectarivorous bats were not detected. The morphological features of T. pasacana flowers were similar but bigger compared to other columnar cacti. Anthesis time was also longer while nectar production was lower. T. pasacana pollination at National Park Los Cardones is done by bees.

    Pulmonary diseases are common among HIV infected patients. The prevalence of the different diseases varies greatly. To identify the different pulmonary diseases that affect a Chilean population of HIV infected patients and to identify factors associated with in hospital mortality. Retrospective review of the clinical records of all HIV infected patients with lung diseases discharged from our institution during a period of 3.5 years. Collection of demographic and biomedical data. One hundred seventy one patients (aged 35.7 years, 86% men) had 236 episodes of lung diseases. Only 13.5% of the patients were receiving antiretroviral therapy and 18% were on pneumocystis prophylaxis. Infectious diseases accounted for 87% of the discharges, neoplasm for 5.1%. Pneumocystis jirovecii infection was responsible for 37.7% of the episodes, community acquired pneumonia was seen in 24.1% and mycobacterial diseases in 14.4%. Two or more conditions were present in 13.6%. Death during hospital stay occurred in 19.5%. Multivariate analysis identified pneumothorax as the only significant independent predictor of in-hospital mortality in patients with pneumocystis pneumonia, while nosocomial pneumonia was the only predictor of death among patients with non-pneumocystis pulmonary diseases. Infectious diseases were the main cause of hospitalization among Chilean HIV infected patients. Mortality among these patients remains high. Appropriate antiretroviral therapy and prophylaxis may alter pulmonary disease prevalence in the future. Every effort should be made to avoid the development of pneumothorax and nosocomial pneumonia.

    We carried out surveys realized field work from March to September 2000 to get the current distribution of Cebids in the state of Campeche, Mexico. Based on interviews and direct observations. We defined the distribution of Ateles geoffroyi yucatanensis and Alouatta pigra and we documented the first time localities where Allouata palliata is found in the state. We made distributional maps of each species using vegetation overlays from Inventario Nacional Forestal (Inv For) and each point documented during fieldwork. We presented the distribution of species according to confiability of the verified or expected data. Using the attributes table of Inv For, we calculated the areas of distribution which were 22,735 km2 for Alouatta sp. and 18,501 km2 for A. g. yucatanensis. We also presented the area occupied by each species according to vegetation types and the relative proportion of these vegetation types in the state. We confirmed the ability of Alouatta sp. to survive in disturbed environments produced by habitat fragmentation, and the affinity of A. g. yucatanesis to well preserved habitats.

    Invasive prenatal diagnosis (IPD) allows identification of fetal diseases, mainly aneuploidy. With the addition of first-trimester prenatal screening and structural ultrasound, IPD indications have changed. To describe the current indications for IPD in pregnant patients at INPer. Descriptive and retrospective study. We reviewed medical records of patients in which IPD was performed during a period of 2.5 years. A total of 339 studies were performed: 81% by amniocentesis (AC), 13% by chorionic villus sampling (CVS) and 6% by cordocentesis or somatocentesis. The most common indications for AC were: advanced maternal age (AMA) (43%), fetuses with multiple defects by ultrasonido (23%) and presence of soft markers for aneuploidies (9%). For CVS were: cystic hygroma (24%). Increased nuchal translucency (NT) (24%), and AMA (18%). When the indication was only AMA, 1.5% of fetus presented aneuploidy. In women under 38 years and normal ultrasoud, chromosomal abnormalities were not detected. The increased NT in women <35 years had a 21% detection and in patients > 35 years it increased to 33%. We observed that the group who had normal translucencia nucal and AMA presented a low risk of chromosomal abnormalities. In the presence of an increased NT, 33% of fetuses were affected, so that measuring TN is considered the best non invasive PD tool. The average age with cytogenetic abnormalities was above 38 years, so we suggest to offer IPD in women above 38 years-old.

    The diagnosis and treatment of thyroid disease has significantly changed with time. With the aim of analysing changes in thyroid surgery in our institution, a representative sample of patients from the first three years in four decades (1960-1992) were comparatively analysed. In the sixties, the diagnosis of thyroid cancer was made during surgery; by contrast, this diagnosis was correctly done by fine needle aspiration (FNA) in most patients of the last decade. Thyroid lobectomy, infrequently used in the treatment of differentiated thyroid carcinoma in earlier times, has now been abandoned and currently most patients undergo total or near-total thyroidectomy. Complications such as hypoparathyroidism and recurrent laryngeal nerve paralysis have importantly decreased with time and were not seen in the last decade. A trend toward an earlier diagnosis of thyroid carcinoma was also observed. In summary, the number of thyroidectomies for benign diseases has been importantly reduced by the use of FNA with the proportional increment of surgery for malignant disease.

    The purpose of this retrospective study was to study the incidence of idiopathic and secondary forms of membranous nephropathy in our institution, its clinical course and progression to chronic renal failure, and the risk factors associated with it. Two hundred fourteen (16%) of the 1,287 renal biopsies obtained between 1962 and 1988 were primary glomerular diseases and 28 of this 214 (13%) were idiopathic membranous nephropathy. On the other hand 59 of 1,287 biopsies were membranous nephropathy of whom 28 were idiopathic, 27 secondary to systemic lupus erythematosus, 2 due to drugs, one associated with rheumatoid arthritis, and one more with breast cancer. The clinical picture was: nephrotic syndrome in 84%, hypertension in 15%, non-nephrotic proteinuria in 14%, chronic renal failure in 8.4%, and renal vein thrombosis in 6.3%. In the idiopathic group 75% of the patients were male while in the lupus group 85% were female. For the analysis of progression to chronic renal failure we excluded 5 patients with renal failure when the biopsy was taken, 2 because the nephropathy was due to drugs, one associated with breast cancer, and nine were within the first year of follow-up. Thus, for this analysis the group consisted of 22 patients with idiopathic form and 20 with systemic lupus erythematosus. The idiopathic and lupus groups were similar except for a lower serum albumin in the former. The progression to renal failure was seen in 9 patients: six in the idiopathic group and the other 3 in the lupus group; this difference was not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

    Mesenteric cysts are rare abdominal tumors. About 60% of these cysts occurs before 5 years of age and can be located anywhere in the gastrointestinal tract, but are most often found in the small bowel mesentery. The clinical presentation depends on the location and size of the cyst and many cases are asymptomatic and are diagnosed incidentally. The most common symptoms are abdominal pain, bloating, abdominal mass, nausea, vomiting, constipation, diarrhea, weight loss, fever and peritonitis. Complications include torsion, infarction, volvulus formation, perforation, infection, anemia, intracystic hemorrhage, intestinal obstruction and obstructive uropathy. They are typically treated by simple excision, marsupialization or segmental bowel resection and have excellent long-term prognosis.

    Surgical treatment is the first option for patients with obstructive multinodular goiter. The extent of the resection and the use of postoperative hormonal therapy are, on the other hand, still under debate. To analyze the results of surgical treatment in 101 patient with multinodular goiter seen from 1980 to 1995. The clinical/pathologic charts of all patients were reviewed with emphasis to the clinical diagnosis, extent of resection, final histology, type and number of complications, and long-term follow-up. The mean follow-up was three years (range 0.5-12). Ten males and 91 females with a mean age of 46 years were included. Surgery was recommended for a nodule suspicious of malignancy in 60 patients, for airway compression in 33, and for cosmetic reasons in eight. Unilateral lobectomy was performed in 30, bilateral subtotal thyroidectomy in 55 and total thyroidectomy in 16. Postoperative hormone therapy was administrated to 83 patients. Surgical complications occurred in six patients. Four developed permanent hypoparathyroidism and two vocal cord paralysis. There was no operative mortality. A final diagnosis of multinodular goiter was established in 89 whereas 12 had cancer. There were three asymptomatic recurrences in the group with benign lesions (they had undergone unilateral lobectomy followed by hormonal therapy). Bilateral subtotal thyroidectomy was the best treatment for multinodular goiter in our series. This procedure had few complications and there was no recurrence of the disease.

    Anaplastic thyroid carcinoma (ATC) is a highly aggressive tumor with a median survival rate of 6 months. To analyze presentation, treatment, morphology, immunohistochemistry, and nuclear DNA analysis of a cohort of patients with ATC. Twelve patients with ATC (11 female) with a mean age of 65 years were seen at our hospital from 1970-1995. The data were obtained from the clinical records and the morphology, immunohistochemic studies and DNA pattern were performed in slides obtained from archival specimens. Previous or coexisting thyroide disease was documented in 10 patients (9 multinodular goiters and one Grave's). The most frequent presentation was a rapidly growing tumor associated with dysphagia, cervical pain, hoarseness and dyspnea. A cold thyroid nodule was detected by thyroid scan in 10 patients. The most frequent subtype was the spindle cell variety. Papillary thyroid carcinoma coexisted in eight cases, two of them corresponded to the tall cell variant. Reactivity for S-100 protein and vimentin was studied in six patients: all were positive for S-100 protein and vimentin, 5/6 for epithelial membrane antigen, half for carcinoembriogenic antigen, 2/6 for thyroglobulin and calcitonin, and one for neuronal specific enolase. These six tumors showed a diploid DNA pattern. Tumor resection was achieved in 2/11 and none survived six years after diagnosis. ATC is a highly aggressive tumor coexisting with thyroid pathologies. Spindle cell variant is the most frequent with positive reactivity for S-100 protein, vimentin and epithelial membrane antigen. Most tumors have a diploid DNA content.

    The AMS system at CNA has been the first 1MV compact AMS system designed and manufactured by HVE. In this paper we present the experimental set-up for (129)I measurements in this facility. Charge state +3 has been selected at high-energy side and an optimum stripper pressure of 6×10(-3)mbar of argon (mass thickness of about 0.15μgcm(-2)) has been reached to obtain lowest blank values ((129)I/(127)I≅3×10(-13)). The measurements of the reference materials provided by the IAEA have demonstrated the viability of this facility to make routine measurements of (129)I at environmental levels. This blank value obtained is enough for the measurement of most environmental samples and comparable with other reported backgrounds obtained in facilities working at higher energies and higher charge states.

    The ingestion of foreign bodies (EC) is a problem commonly seen by pediatricians and emergency physicians. The intake is almost always accidental and most common objects are coins, pieces of toys, jewelry or batteries. The button batteries are the most common, in which case is important early diagnosis and removal. The cylindrical battery ingestion is very rare, are typically alkaline manganese or nickel-cadmium (rechargeable) and when ingested they can cause toxic and corrosive damage. Such damage may occur as a result of the effect of acid gastric contents sustained over a period of days or weeks. We report the case of a patient who accidentally ingested a cylindrical battery, which was removed from the stomach endoscopically without complications.

    We have analysed the meals for lunch and dinner at the University cafeteria, during one Winter week (June through September); in this season the menus are repeated every week round. A percentage analysis (humidity, ashes, lipids, protein, raw fiber, and nitrogen-free extract) was carried out on the sample, which were appropriately processed, thus allowing us to know the nutrients amount and caloric value of each meal. When examining both the formulas ingredients and the technique applied to the preparation of the meals, it was found that they have the best cooking quality, and also that their amount is sufficient (see tables). As to the meals nutrients, the results allow us to conclude that the diets are hypercaloric as well as hypoproteic, with a preponderance of proteins of animal origin.

    2000-12-01

    This paper is the second part of a base line study carried out in the coastal region near a marine service station located in Morrocoy National Park, Venezuela. Results from a physical and chemical characterization of the water and sediments of four sites located around the service station are presented. The physical and chemical factors measured in water included: temperature, salinity, specific conductance, dissolved oxygen, saturation percentage of dissolved oxygen, pH, total suspended solids, transparency, oil and grease, total residual petroleum hydrocarbon, vanadium and lead, total coliform bacteria, and the presence of coliform bacteria. The factors measured in sediments include: granulometry, organic material, total carbonates, vanadium, lead, oil and grease, and total hydrocarbons. In addition, the amount of vanadium and lead in sample tissue from three species which are abundant and widely distributed in each site was measured in order to evaluate the potential of these species as bio-indicators. The water in the area where this study was conducted is shallow, warm, and thermally homogeneous, with high salinity and normal pH and dissolved oxygen, and supersaturated with oxygen in certain hours in sites adjacent to abundant underwater vegetation. The water is moderately turbid with a tendency towards less dissolved oxygen with increased depth. The estimated values of NMP/100 ml of the coliform fecal organisms is within legal limits even though the total number of water coliforms measured in Site 2 was ten times higher than in Site 1. This increase is associated with the proximity of Site 2 to an outflow of pre-treated sewage. The values of TRPH in the water collected from each site were low and very close to the detection limit (0.8/ml). Vanadium was not found, while lead was detected in 11 of the 12 samples. Compared to the values measured for Site 1, which was the local reference, only one sample had a concentration of three times the maximum baseline. The amount of lead found in all analyzed samples was acceptable, according to the standards set by the State of Washington (maximum value: 292 mg/kg), while the concentration of lead in the sediments around the supply dock were 1.5 to 3.4 times greater than the Dutch norm. It can be concluded that there is no evidence of an accumulation of Va or Pb in the species selected as bioindicators. An observation program is proposed in which variables similar to those measured for this characterization will be studied with some modifications. A more intense sampling of some variables is recommended (lead in water and sediments, total coliform and fecal matter in consecutive samples and in days following a high concentration of visitors) as is the elimination or minimization of other variables.

    Mechanical aortic valve replacement (AVR) results have been published extensively in industrialized countries. To assess our immediate and late results in patients subjected to AVR. We retrospectively studied 194 patients subjected to isolated AVR between 1995 and 2003. Mean age was 57 +/- 13 years and 119 (61%) were male. One hundred thirty nine (73%) were in functional class III-IV, 20 (10%) had a previous cardiac operation and 25 (13%) were operated as an emergency. Surgical indication was stenosis in 110 (58%), regurgitation in 49 (26%) and stenosis/regurgitation in 31 (16%). Etiology was bicuspid valve 56 (29%), degenerative lesions 55 (28%), rheumatic valve disease 38 (20%) and endocarditis 27 (14%). Medtronic Hall was the most common prosthesis used in 157 patients (81%). Mean cardiopulmonary bypass time 97 +/- 29 min and mean cross clamp time was 69 +/- 21 min. Operative mortality was 4.6% (3% in elective surgery, 16% in emergency surgery and 0% in reoperations). Follow-up was complete in 100% of cases, totalizing 636 patients-year. Survival was 91 +/- 2%, 80 +/- 4% and 73 +/- 6%, at 1, 5 and 7 years, respectively. Multivariate risk analysis identified renal failure and endocarditis as predictors of early and late mortality. During follow up, the linear incidence rate for hemorrhage was 3.29% /patients-year, thromboembolism 2.04% patients-year and endocarditis 1.1% patients-year. AVR has low overall and elective mortality. Midterm survival is good but linear event rates related to anticoagulant treatment are higher than those previously published in industrialized countries. Renal failure and endocarditis were risk factors for early and late death.

    The rising antimicrobial resistance of streptococcus pneumoniae, requires permanent surveillance. Antimicrobial treatments of invasive infections must be modified accordingly. To assess the in vitro antimicrobial susceptibility of streptococcus pneumoniae strains isolated from lower respiratory infections. Seventy five strains isolated during three periods in consecutive years were studied. In vitro susceptibility towards penicillin, erythromycin and ceftriaxone was studied using E-test technique minimal inhibitory concentrations. Five percent of strains were penicillin resistant and 11% had an intermediate sensitivity. Erythromycin resistance was observed in 1.3% of strains. Eight percent of strains had an intermediate sensitivity towards ceftriaxone and no resistance was observed. Comparing susceptibility in the three studied periods, it remained low and stable. High and intermediate resistance of Streptococcus pneumoniae towards penicillin is less prevalent than in other countries. A close surveillance must be maintained (Rev Méd Chile 2002; 130: 304-8).

    Physiology, environment and life history demands interact to influence marine turtle bioenergetics and activity. However, metabolism and diving behavior of free-swimming marine turtles have not been measured simultaneously. Using doubly labeled water, we obtained the first field metabolic rates (FMRs; 0.20-0.74 W kg(-1)) and water fluxes (16-30% TBW day(-1), where TBW=total body water) for free-ranging marine turtles and combined these data with dive information from electronic archival tags to investigate the bioenergetics and diving activity of reproductive adult female leatherback turtles Dermochelys coriacea. Mean dive durations (7.8+/-2.4 min (+/-1 s.d.), bottom times (2.7+/-0.8 min), and percentage of time spent in water temperatures (Tw) < or =24 degrees C (9.5+/-5.7%) increased with increasing mean maximum dive depths (22.6+/-7.1 m; all P< or =0.001). The FMRs increased with longer mean dive durations, bottom times and surface intervals and increased time spent in Tw< or =24 degrees C (all r2> or =0.99). This suggests that low FMRs and activity levels, combined with shuttling between different water temperatures, could allow leatherbacks to avoid overheating while in warm tropical waters. Additionally, internesting leatherback dive durations were consistently shorter than aerobic dive limits calculated from our FMRs (11.7-44.3 min). Our results indicate that internesting female leatherbacks maintained low FMRs and activity levels, thereby spending relatively little energy while active at sea. Future studies should incorporate data on metabolic rate, dive patterns, water temperatures, and body temperatures to develop further the relationship between physiological and life history demands and marine turtle bioenergetics and activity.

    Biodiversity studies allow ecosystem assessment and monitoring of environmental changes and impacts. Parasite diversity could reflect the host/ parasite coevolutionary process and the environment changes that permit the loss, gain or maintenance of species. This survey used species/morphotypes of helminths eggs found in feces from seven wild mammal species (the groups Dasypodidae and Large Cats, and Tamandua tetradactyla, Cebus apella, Alouatta caraya, Cerdocyon thous, Pecari tajacu) and from two domestic species (Canis familiaris and Sus scrofa), which occur within the Serra da Capivara National Park (PNSC) and surrounding areas in order to analise the diversity of mammal intestinal helminths. This work used the helminthological fauna findings of wild and domestic mammals, to consider a possible helminth flux between these two host groups using Unweighted Pair Group Method with Arithmetic Mean (UPGMA) of the hosts based on helminthological fauna composition. The results indicate that the region of the PNSC still maintains environmental conditions that still keep wild mammal helminthological fauna composition different from the one found for domestic mammals.

    Hospital statistics are very important as tools that help to define research objectives and design health programs. To determine the main causes of hospital morbility at the Manuel Velasco Suárez National Institute of Neurology and Neurosurgery (MVS-NINN) between 1995 and 2001. Data were taken from the electronic database of morbidity and mortality of MVS-NINN. All outpatient records between 1995 and 2001 were considered. We calculated trends and specific rates of morbidity per 100 discharged patients. The main causes of morbility were brain tumors, schizophrenic illness, neurocysticercosis, and stroke. We found a statistically significant declining time-trend of schizophrenic illness and in non-traumatic brain hemorrhage in males. In the case of females, we observed an increasing time-trend of benign meningeal tumors. The age groups more affected in both genders were those < 51 years of age. This study is not a population study, but it helps to increase knowledge of the main causes of hospitalization at one of the most important neurologic institutions in the world, which provides care for thinsured population throughout Mexico. These findings facilitate analysis and decision-making to undertake specifications to improve the quality of neurologic medical attention.

    Medical research is a fundamental tool to achieve the advancement of science, through the improvement of strategies aimed to protect, promote and restore an individual's and society's health. Three characteristics are required to obtain approval of the research proposal: scientific relevance, technical quality and the accomplishment of ethical issues. The present review aimed at the determination of the specific criteria to perform a critical review of research proposals. A research was carried out in the PubMed, Medline, Ovid and Google Scholar databases, using the terms: peer review, research proposals, review and protocols, and reviewers. A total of 3546 related articles were reviewed, without finding a guide to critically assess research proposals. The guides to assess research articles consider that the quality criteria of the study should have been present since the study's conception; many of the issues described to review articles are incorporated in the review of the research proposals. The specific criteria were integrated to allow the reviewer to critically assess research proposals of different areas with scientific basis. The reviewer of research proposals should be considered as a professional that contributes to the promotion of knowledge advancement through his/her comments, which allow researchers to improve the quality of research proposals.

    Most patients with multiple myeloma have an abnormal band in the gamma region of protein electrophoresis. To correlate the clinical diagnosis with patterns of protein electrophoresis. Retrospective analysis of all protein electrophoresis or immunoglobulin quantification requested during 1992 and review of clinical charts of patients. During 1992, 553 protein electrophoresis were requested. Of these, 344 were repetitions and 209 came from patients seen for the first time. Among the latter, we found a monoclonal component in 40. Of these 40 patients, 35 had a multiple myeloma, one had a plasmocytoma and four a non-Hodgkin lymphoma. Fourteen patients with diagnosis of myeloma did not have a monoclonal component in protein electrophoresis. These figures resulted in a 71% sensitivity and 97% specificity for monoclonal components in the diagnosis of multiple myeloma. The monoclonal component of patients with myeloma was characterized as IgG in 29 (60%), IgA in 5 (10%) and IgM in one. A monoclonal component present in a protein electrophoresis has a high diagnostic accuracy for multiple myeloma.

    The productive character of the scientific thought points out a methodological means that include the demand of the students' job about the information and not his mere reception and reproduction. It is essential to give the students the opportunity of discovering the cognitive processes used in the production of the scientific knowledge. In this work, we present the result of the starting of a workshop dynamic in a basic subject, the students' answers, and the analysis of the subject. In the Chair of Medical Bacteriology and Virology of the School of Medical Sciences, the National University of Córdoba, 1700 students attended classes in 1997. The subject was developed with the activities that worked the same contents from two different learning conceptions: (I) workshop activity, non obligatory, constructive, and (II) theorico-practical activity, obligatory and traditional. Two voluntary and anonymous interviews were done about the valuation that the student gave to these two activities and their basis, one in the middle and the other at the end of the course. 90.55% classified the traditional activity as positive, and 9.45% as negative. Regarding the workshop activity, the 60.5% classified it as positive and the 39.5% as negative. The same developed content with two activities made possible the analysis of the impact that the two different methodologies produced on the students. The student's answer to the traditional activity was better than the workshop activity (p < 0.001). The differences in the student's acceptance between the two option revealed the major difficulty of an alternative methodological strategy in the current educational model.

    Up to now, the best treatment for patients with acute myelogenous leukemia (AML) is the induction of bone marrow hypoplasia by ablative combined chemotherapy; the prototype of these schedules is the so-called 7 + 3 (seven days of continuous infusion of cytarabine and three days of one-hour infusion of any anthracycline); these schedules require the support of both platelet transfusions and antibiotics. Other non-ablative schedules have also been tried in the treatment of such patients. Here we analyze the results of the treatment of 76 adult patients with AML; 43 were treated with the classical 7 + 3 schedule, whereas 33 were treated with a combination of chemotherapy used in non-ablative doses (TADOP: thioguanine, arabinosyl-citosine, doxorrubicin, vincristine and prednisone). The results were as follows, respectively, for 7 + 3 and TADOP: complete remission (CR) was achieved in 60 and 48% of patients (p NS); the number of cycles to achieve CR had a median of 1 and 5 months (p less than 0.001); the median duration of the CR was 21 and 10 months (p less than 0.05); fatal myelotoxicity was 30 and 42% (p NS), one-year disease free survival (DFS) was 45 and 46% (p NS) and three-year survival was 22% and 15% (p NS). Additionally, patients treated with 7 + 3 were divided into two groups according to the type of platelet transfusion support; those supported with apheresis equipment and those with centrifugation-derived platelets.(ABSTRACT TRUNCATED AT 250 WORDS)

    40 patients with DMPS were studied and diagnosed at the INNSZ during 1980-1985. Eighteen were males and twenty two females; age average of 55.7 years (17-82), with 72.5% over 50 years old. Their distribution according to the FAB classification was: 55% type I, 10% type II, 27.5% type III, 2.5% type IV and 5% type V. All of them had an anemic syndrome and 47.5% had bled, 52.5% had pancytopenia; there was anemia and thrombocytopenia in 32.5%, anemia and leukopenia in 7.5%, and anemia only in 7.5%. The bone marrow was normocellular in 42.5%, hypercellular in 40% and hypocellular in 17.5%, 45% of the patients survived; 22% achieved a complete remission (CR) and 9 patients (22.5%) died of causes related to DMPS. The rest was lost to follow up.

    Tobacco use presents an odd confluence of circumstances: it is a significant and high threat to health, and there is a lack of motivation among health workers to act accordingly. Yet we have effective interventions. It is really hard to identify any other determinant of health presenting this mixture of lethality, prevalence, and lack of care, despite having effective treatments readily available. On the other hand, smoking cessation interventions are considered as the gold standard of preventive interventions, far above other preventive measures commonly used. This has prompted the National Committee for Smoking Prevention to develop a consensus document for the Clinical Care of Smoking Cessation in Spain. The purpose of this technical and scientific document is to agree on a basic proposal of quality of care to tackle smokers to quit. This document would serve as a guideline in the clinical practice in our country. The aims of this agreement are to review the effectiveness of the existing therapies for smoking cessation, to synthesize their available evidence, and to set the basic minimum standards of care in the clinical practice of patients who smoke. The consensus sets the strategies, and the evidences that support them, in order to assist both the smokers who want to quit, and the smokers who do not, setting out the steps to intervene in the most adequate.

    Objetivos. Nos propusimos determinar el grado de preparación frente a los desastres naturales de los adultos mayores en los Estados Unidos y evaluar los factores que pueden afectar negativamente la salud y la seguridad durante este tipo de incidentes. Métodos. Obtuvimos una muestra de adultos de 50 años en adelante (n = 1 304) de la encuesta del 2010 del Estudio de la Salud y la Jubilación (HRS por su sigla en inglés). La encuesta recogió datos sobre las características demográficas generales, el estado de discapacidad o las limitaciones funcionales, y también sobre factores y comportamientos relacionados con la preparación frente a los desastres. Calculamos una puntuación global de preparación mediante indicadores individuales a fin de evaluar el grado de preparación general. Resultados. La media de la edad de los participantes (n = 1 304) fue de 70 años (desviación estándar [DE] = 9,3). Solo 34,3% informaron que habían participado en un programa formativo o que habían leído materiales sobre la preparación para los desastres. Casi 15% indicaron que usaban dispositivos médicos eléctricos que podían correr riesgo de no funcionar si se interrumpiera el suministro eléctrico. La puntuación de preparación indicó que la edad más avanzada, la discapacidad física y el menor nivel de escolaridad y de ingresos se asociaban independiente y significativamente a un grado de preparación general inferior. Conclusiones. A pesar de la mayor vulnerabilidad ante los desastres y del número cada vez mayor de adultos mayores en los Estados Unidos, muchos de los problemas sustanciales que encontramos son remediables y requieren atención en los sectores de la sociedad dedicados a la atención clínica, a la salud pública y al manejo de situaciones de emergencia.

    Primary and secondary prevention trials have demonstrated that niacin improves the lipid profile and reduces coronary morbidity and mortality. To investigate the safety and efficacy of niacin in daily doses of 1.5 and 3.0 g in patients with ischemic heart disease and dyslipidemia. Sixty one male and female patients, aged 30 to 70 years were included. Thirty two patients were later excluded; 18 for adverse events and 14 for causes not related to niacin. In the 29 patients that finished the study, niacin in a dose-dependent manner, significantly reduced the levels of total cholesterol, LDL-cholesterol, triglycerides, apoB and LDL-C/HDL-C ratio, and significantly increased HDL-Cholesterol concentrations; a decrease in lipoprotein(a) was observed with both dosages, but the change was significant only with the 3.0 g/day. In 11 patients (38%) lipids and lipoproteins reached ideal concentrations. In 15 patients (52%) C-LDL/C-HDL was lower than or equal to 3.5 at the end of the study. Our results suggest that niacin is well tolerated by 62% of the patients. Niacin is a safe, effective and a low cost alternative in the treatment of patients with ischemic heart disease and dyslipidemia.

    Surgical treatment for anorectal fistula may be difficult because of the risk of recurrence, prolonged healing or anal incontinence following the operation. To analyze the experience with the surgical management of ano-rectal fistula during a period of 17 years. The medical records of 105 patients with anorectal fistulas were reviewed retrospectively, with analysis of demographic and clinical data, operative treatment, and results. There were 73% men and 27% women. Mean age was 45 years. 86% had an underlying chronic disease, most frequently diabetes mellitus (21%) and obesity (14%). No anatomic classification of the fistulous tract was done in 86% of cases, and inter-sphincteric tracts were the most frequent type in the classified cases. In 90% of cases, treatment was fistulectomy. Complications occurred in 13% of cases, mainly delayed healing (6.5%). Recurrent disease was documented in 11 cases (10%), and the majority were treated with a new fistulectomy. There were no cases with anal incontinence following the operation. The necessity of performing the anatomic classification of ano-rectal fistula should be emphasized. Fistulectomy was the most frequent surgical procedure.

    To analyze morbidity-mortality and results of surgical treatment for colonic volvulus. Retrospective review of 33 patients who underwent surgical treatment for colonic volvulus from 1986 through 1996. Mean age was 62 +/- 20 years (SD) with predominance of female sex (2:1). There were 25 cases of sigmoid volvulus (76%), 7 in the cecum (21%) and 1 in the transverse colon (3%). Colonic necrosis and/or perforation were most frequently seen in the right and transverse colon (50%) than in the sigmoid (4%) (P < 0.002). Operative morbidity was 45% with mortality of 21%. Age was the only variable statistically significant for operative morbidity (52 +/- 23 years in patients without morbidity vs 71 +/- 17 years in patients with morbidity, P = 0.02). Surgical procedures for sigmoid volvulus were resection in 13 and fixation in 12. Recurrence after fixation was 38% to 12 months and 69% to 24 months (Kaplan-Meier), with associated mortality of 50%. There was no recurrence after resections. Treatment for cecal volvulus was cecopexy in 4 cases, with one recurrence; and right hemicolectomy without recurrence. The results should encourage resective procedures in sigmoid volvulus because the risk of recurrence after fixation is high and the morbidity-mortality is similar. Elderly patients are more susceptible to complications.

    To know the frequency, trends and associated factors of peptic ulcer disease in our Institute. Peptic ulcer is an important disease; about 5-10% of the population can expect to develop this disease during lifetime. We reviewed 1,123 patients with peptic ulcer in five years. Sex, age, habits (tobacco and alcohol consumption), non-steroidal anti-inflammatory drugs use, ulcer location and complications were analyzed. To evaluate temporal trends, our results were compared with previous studies made in our Institute. The male-female ratio was 1:1, with a mean age of 52.2 years. Forty percent of the patients had duodenal ulcer, 42% had gastric ulcer, and 19% had esophageal, anastomotic or multiple ulcers. The most common complication was bleeding, which occurred more frequently in gastric (37%) than duodenal ulcer (24%) (P < 0.005). Gastric ulcer occurred in older patients when compared to duodenal ulcer (P < 0.02). Non-steroidal anti-inflammatory drugs consumption was more frequent in patients with gastric (14%) than duodenal ulcer (10%) (P < 0.04). The frequency of tobacco and alcohol consumption was higher in multiple ulcers. A tendency toward a decreased frequency of duodenal ulcer and increased frequency of gastric ulcer was observed in our Institute during the last 30 years. In the same period, bleeding has been the leading complication, suggesting a higher referral of complicated peptic ulcer.

    Lower gastrointestinal bleeding is usually self-limiting in about 80% of cases; however, surgical treatment may be required in selected cases. Preoperative precise identification of the bleeding source is crucial for a successful outcome. To determine the most frequent diagnoses, as well as short and long-term results in a series of patients who underwent a surgical procedure for lower gastrointestinal bleeding. Retrospective analysis of 39 patients operated upon for lower gastrointestinal bleeding from 1979 through 1997 in a referral center. Demographic data, history, physical examination, laboratory tests, resuscitative measures, preoperative work-up for identification of bleeding source, definitive cause of bleeding, surgical procedure, operative morbidity and mortality, as well as long-term status and recurrence of bleeding were recorded. There were 54% women and 46% men. Mean age was 56 years (range, 15-92). Most patients presented hematochezia (69%). Colonoscopy was the most used diagnostic procedure (69%). The bleeding source was located in 90% of patients. Diverticular disease was the most frequent cause of bleeding. A segmental bowel resection was the treatment in 97% of cases. Morbidity was 23% with 18% of mortality. Recurrence occurred in 9% of survivors. Morbidity and mortality were high. Patients who require a surgical operation should be carefully selected and evaluated with a complete work-up to determine the site and cause of bleeding.

    At the recently created Astronomical Museum ``Pte. Sarmiento - Dr. Benjamin Gould", the task of preventive conservation of historic documents has been faced. These materials include: 1) letters exchanged between national authorities and the directors of the Observatory, during the first decades (1870-1880-1890); b) original observation logs from these very first times, containing astrometrical and photometrical data; c) a variety of ancient books and papers; d) administrative documents. The state of conservation of this patrimony was varied: since well-conserved books and letters, to highly degraded logs. The observation logs written by B. Gould and the astronomers who followed him had been stocked in a safe with a permanent humidity of about 70 %, without any ventilation and exposed to the attack of insects of the family ``dermestidae." These conditions could not be worse for the conservation of paper. In order to stop the proccess of degradation and create a healthy environment for written-paper conservation, a team was formed with personnel belonging to the Cultural Area of the Municipality. The tasks being performed on the observation logs are: 1) an initial, mechanical cleaning, performed once the material is extracted from the contaminated safe: by these means, adult insects and pupas are removed 2) a stage of about two weeks of duration, in which the logs are mantained in a vacuum chamber, in orden to completely eliminate the adult, pupa and egg stage insects by anoxia 3) the final mechanical cleaning 4) storage in a clean location. In order to perform these tasks, we work in collaboration with the Environmental Observatory of the City, and the group of Material-Science Research of Fa.M.A.F. Regarding the letters, a mechanical cleaning was performed. After that, the letters were digitized by means of a scanner, inventoried, put inside acid-free polipropylene envelops and filed for conservation, protected from intense light and external sources of contamination. Copies of these letters will be included as exhibits.

In the pursue of the objective, the author depicted: personal and professional traits of the nurses; job satisfaction and perceived support from the administration; the most frequent nurses activities performed. It also established the relations between nurses traits, job satisfaction, perceived support, and activities performed. Data was collected from March to December 1984. The questionnaires were sent to the universe of working nurses in the outpatient centers--1158 nurses. 927 (80.1%) answers were obtained. The population studied represented: 94.3% female, majority married; 30 to 40 years old, year of graduation and year of admission in the INAMPS in the 70's. Gross results were: job satisfaction 83.6%, perception of support from administration 75.2%, prepared as specialists 71.3%, and frequence to continuing educational programs 84.1%. Mains activities performed by nurses in decreasing order: supervision of nursing personnel 39.3%, direct nursing care 36.7%, teaching of patients and families 21.7%, administrative--functions 17.9%, and inservice training of personnel 3.6%. No relation was demonstrated between graduate preparation and job satisfaction nor perceived support from administration. Positive relation was found between educative activities and job satisfaction, and between supervision of nursing personnel or performance of administrative functions and perception of support from the administration.

The newspaper chronicles by Lima Barreto, countless letters, scientific papers, and unpublished texts by Bertha herself that are surveyed in this article indicate how much her feminism--inseparable from other dimensions of her life--fostered her professional career. Her feminism earned her a carefully constructed renown and visibility that interlocked with her professional performance. Science lent her social prestige and guaranteed legitimacy for her causes. During a period when the scientific community itself was engaged in publicizing its own activities, Bertha's feminist prominence in the media helped her make a name in the sciences.

    Primary hyperparathyroidism (PHPT) is a frequent disease. It is characterized by hypercalcemia and elevation of parathyroid hormone (PTH) levels. The incidence is variable, being more frequent in women (3:1) in the perimenopauseal period. In the last decades, diagnosis of asymptomatic PHPT has increased due to automatized calcium determinations. Duration of the disease and serum concentrations of calcium and PTH determine symptomatology. Surgery is the definitive treatment. It is important to assess surgical criteria in asymptomatic patients. Successful treatment of this disease depends on a highly specialized team of parathyroid surgeons. We reviewed the clinical and biochemical background of patients subjected to parathyroidectomy from January 1998 to August 2003 in our medical center. We then analyzed clinical and laboratory data, final histopathologic diagnosis, and surgery outcome. Sixty seven patients were included, with an average age of 50 years (+/- 11.9), 15 men and 52 women. Greatest frequency of PHPT was observed in patients between 40 and 60 years of age. Average calcium value was 11.7 mg/dl (+/- 1.23) and that of PTH was 194.5 pg/ml (+/- 93). Histopathologic diagnosis was adenoma in 56 (83.58%), hyperplasia in 9 (13.43%), and carcinoma in 2 (2.9%) patients. Cure of the disease was achieved in 65 patients (97%). PHPT is a surgically curable disease; it is necessary to confirm diagnosis and decide on surgical treatment in accordance with established criteria even if the disease is asymptomatic.

    During two full years--from October 1980 to September 1982--we captured sandflies in the National Park of Serra dos Orgãos, State of Rio de Janeiro, Brazil. The captures, with human bait, were carried out weekly, each with a duration of two hours, and at three different times (6 to 8 a.m., 5 to 7 a.m. and 7:30 to 9:30 p.m.). In every capture, we recorded the phase of the moon and, at each hour, the temperature, relative humidity, wind and rain. In 586 hours 4,834 sandflies of ten species were captured, all belonging to genus Lutzomyia França, 1924. L. ayrozai and L. hirsuta represented 92% of the total species captured. However, they were dominant at different times, the former being more frequent in the warm and wet months, and considerably declining in the cold and dry months, in which the latter gradually prevailed. L. fischeri and L. shannoni were shown to be the most resistant to unfavourable weather conditions. Whenever there was any rain or wind, they were, in general, the only species captured. With regard to lunar cycle, we observed that new moon was the most favourable phase for the capture of sandflies and full moon the one with the smallest yield, except for L. shannoni which occurred more frequently during this period.

    The purpose of this work was to study the volatile composition of vine leaves and vine leaf infusion prepared from vine leaves collected at 30 and 60 days after grape harvest of two Vitis vinifera L. species. Eighteen volatile compounds were identified by gas chromatography-mass spectrometry in vine leaves and in vine leaf infusions. It was observed that the volatile compounds present in vine leaves are dependent on the time of harvest, with benzaldehyde being the major volatile present in vine leaves collected at 30 days after harvesting. There are significant differences in the volatile composition of the leaves from the two grape cultivars, especially in the sample collected at 60 days after grape harvest. This is not reflected in the volatile composition of the vine leaf infusion made from this two cultivars, the more important being the harvesting date for the volatile profile of vine leaf infusion than the vine leaves grape cultivar.

    Neuroblastoma (NB) is the most frequent extracranial solid tumor in children according to the literature. In Mexico it is less frequent, fallen to 8th place. Our objective was to analyze our experience and compare it with the one reported in other countries. We included all patients admitted to our hospital during the previous five years and who had not received any treatment. Patients with stages I, II, and IV received cyclophosphamide and epirrubicin. Patients with stages were III and IV received the same chemotherapy alternating with cisplatinum., ifosfamide and etoposide during 12 months as well as massive doses of 131-MIBG and surgical ablation of the remaining tumor when possible. We included 30 patients, 25 with initial presentation in the abdomen. Five were in early stages and 20 (70%) were advanced with an overall survival of 100% and 27% at 5 years respectively. When analyzed by age, 40% were 12 months of age and 60% older, with survival of 100% and 27% in the same period, respectively. According to histology there was 91% survival for differentiated and 23% for undifferentiated tumors. The chemotherapeutic regimen reported is effective but not better than that reported by other authors, in which some benefits are seen with use of transplant and immunotherapy. The most important prognostic factors are still considered to be age, stage and histology.

    At low angles the scattering of X-rays in the diagnostic energy range (low-momentum transfer), it is probable that the scattering interaction will be coherent. This coherence gives rise to interference effects resulting in X-ray diffraction patterns that are characteristic of the scattering material. The usefulness of coherent scattering is not limited to crystallography. It can provide information about biological material as well. The interatomic and intermolecular co-operative effects which modify the free-atom coherent scattering process are well known for highly ordered structures such as crystalline materials but are important for amorphous solids and liquids where short-range ordering occurs. X-ray diffraction using synchrotron radiation has became a well established technique. This work introduces a non-destructive synchrotron radiation X-ray diffraction imaging technique. The feasibility of the X-ray diffraction computed microtomography using synchrotron radiation has been investigated. This research was carried out at the X-ray diffraction beam line of the National Synchrotron Light Laboratory supported by the National Council for Scientific and Technological Development (LNLS/CNPq) in Brazil. These experimental patterns were carried out with a 500 microm slit in front of the detector and an 11.101 keV beam (lambda = 1.117 A) monochromatic beam from the double crystal monochromator. The diffracted beam was detected by a fast scintillation detector (10(6) counts s(-1)) designed specifically to meet the needs of high quality X-ray diffraction and synchrotron radiation experiments. The data were recorded at rates of one second per degree of 2theta (angular steps equal to 0.05 +/- 0.01 degrees) and registered by a multichannel analyzer. These experimental data could be used to evaluate the scattering properties of different tissue-substitute (water, lucite, nylon, plastic and polystyrene) and bone-substitute (hydroxyapatite and aluminum) materials. The data are in good agreement with those obtained by other authors, indicating the feasibility of the imaging technique.

    Upper gastrointestinal bleeding is a digestive disorder with both high morbidity and mortality, being the most important digestive emergency. The objective of study was to find risk factors than increase morbimortality and efficacy treatment of used. The design was is a retrospective case-control study, an aleatory unrestrictive sample was done, with 104 subjects each group, selected by the aleatory numbers table. Risk factors associated to mobility: major bleeding was male population (OR = 1.94, CL 1.08-3.50), previous alcohol consume (OR = 2.47, CL 1.32-4.66); previous peptic ulcer (OR = 2.83, CL 1.16-7.07);chronic liver disease (OR = 4.55, CL 1.36-16.77); haematemesis and melaena (OR = 2.85, CL 1.53-5.34); and only haematemesis (OR = 3.40, CL 1.62-7.23); injury assigned as risk factor were esophagogastric varices(OR = 4.64, CL 1.96-3.42). Combinated treatments medical-endoscopic and medical-surgical treatments were determinate as protectors factors with RR = 0.52 (CL 0.37-0.73) and RR = 0.09 (CL 0.01 - 0.61) respectively. Mortality: 0.40%. Risk factors associated to morbimortality were: chronic liver disease, esophago-gastric varices, haematemesis and melaena. Treatment medical-endoscopic and medical-surgery are protective factors. Mortality: 0.48% can be attributed to improvement of endoscopic treatments and convenient surgery treatment considered as protector factors with high efficacy.

    Formely, the subandean zone in the southeastern Ecuador involved large volcanic and magmatic rocks included in the Misahualli Formation and Zamora batholith, both as expression of the Jurassic cal-alcaline volcanic arc. The aim of the project carried out by the INIGEMM (Instituto Nacional de Investigación Geológico Minero Metalúrgico) was discriminate the volcanic products including a continuous set going from basalts to ryolithes and volcanoclastic rocks. Geochemical characterization was done using representative 16 whole - rock chemical analysis. The oldest rocks of the investigated area called Pachicutza Unit, include greenish to black, massive basalts and basaltic andesites, locally showing pillows structures. The texture is aphanitic to microporphyritic with slight crystal growth of plagioclase and pyroxenes. The Unit include also local pyroclastic breccias and tuffs showing variable skarnification related to the intrusion of the jurassic Zamora Batholith. Two samples of basalts show tholeiitic affinity, corresponding to an N- MORB, probably representing an early stage in opening of a regional Triassic rift reported since Colombia to Peru in the Andes. These geochemical characteristics are similar to the amphibolites of Monte Olivo Unit in the Real Cordillera. The Jurassic large volcanic assembly of the Misahualli Formation was also differenciated. Basal volcanics include green, subporphyritic andesites and volcanic breccias possibly generated at an early stage of the volcanic arc, caused by a change of extensive to compressive regime. Continental volcano sedimentary and sedimentary rock were discriminate as Nueva Esperanza and Suarez Units, respectively. The volcanosedimentary sequence include massive to laminate tuffs and tuffites of intermediate composition. The sediments of the Suarez Unit include dominant conglomerats and sandstones of fluvial domain. The regional volcanic sequence is completed by the Las Peñas Unit that includes aphanitic to

    The Zamora Batholith is an intrusive complex that is located in the extreme south-east of Ecuador. It has dimensions of 200 x 50 km approximately. It is mainly located in the Zamora Chinchipe province from which it takes its name. This study consisted in the petrographic and geochemical characterization of the Zamora Batholith in the area covered by 1: 50,000 geological maps of Centro Shaime, Guayzimi, Paquisha, Los Encuentros and El Pangui. Fieldwork was done by the "Proyecto Mapeo Geológico escala 1:50.000 (zonas prospectivas mineras)" of the Instituto Nacional de Investigación Geológico, Minero, Metalúrgico of Ecuador. This research was performed with 59 thin sections and 10 whole - rock chemical analysis done in the C.I.C of the Granada University. The Zamora Batholith intrudes Triassic to Jurassic volcanic rocks. It is overlaid by sandstones of the Hollin Formation of the Upper Aptian age and shale and limestone from the Napo Formation. Post-cretaceous deposits of ash and lava flows of andesitic to rhyolitic compositions cover the batholith. The petrography of the Zamora Batholith ranges from tonalite to monzogranite with the same qualitative mineralogy. The rocks are composed by different proportions of plagioclase, amphibole, feldspar K, quartz, biotite, opaque, pyroxene and epidote, as accessory minerals has zircon, sphene and apatite. To the south of the Conguime and Guayzimi towns, the dominant petrography is medium to coarse grained amphibole granodiorite with tonalitic and monzogranitic subordinates. To the north monzogranites are dominant rocks and subordinate granodiorites. To the East of Santa Elena the sienogranites are associated with El Hito porphyritic granite that intrudes to Zamora Batholith. Frequently the batholith has propylitic alteration; which produces a primary association of chlorite, epidote, calcite and pyrite. The granitoids have dioritic to granitic compositions (60.09 to 73.6 wt.% SiO2) and are I - type, medium to high-K calc

    Chaitén volcano in southern Andes started a plinian to subplinian rhyolitic eruption on May 2008 following a long period of quiescence. A new dome complex grew up at high rates during 2008-2009 inside a 2 kilometers caldera like structure. Pyroclastic, laharic, block and ash flows and ash falls deposits have been affecting the surrounding populations, ground, vegetation, ocean and rivers, such as the laharic flows burying the currently evacuated Chaitén city. The geological, volcanologic and seismic knowledge produced during the eruption and the determination of evolutionary sceneries were properly transferred and consequently taken in account during complex decisions of authorities in charge of the emergency. As a result, no fatalities or major people injuries were produced during this rhyolitic eruption. Mainly as the consequence of the eruption of the Chaitén volcano but also due to the valuable technical advice during the crisis management, evacuation, hazards evolution, volcanic alerts and selection of sites for relocation of the Chaitén city provided by geologist and volcanologist from SERNAGEOMIN, the funding for the National Volcano Monitoring Network (RNVV) was approved during 2008 and it was integrated as a Bicentenary initiative. During the lapse of 5 year, RNVV need to create professional capacity and working teams, improve the current volcano observatory at Temuco and conform three new observatories at Coihaique, Talca and Antofagasta cities to implement volcano monitoring networks at the 43 hazardous volcanoes along the Chilean Andes. Monitoring net is currently conformed by seismic stations in 10 volcanoes or volcanic groups (San Pedro-San Pablo in Central Volcanic Andes and Llaima, Villlarrica, Mocho-Choshuenco, Carrán-Los Venados, Cordón Caulle, Osorno, Calbuco, Chaitén and Melimoyu in the southern volcanic Andes), in addition to gas measure and video camera stations in Llaima, Villarrica and Chaitén volcanoes. In addition, the geologic and volcanologic knowledge is currently transferred to authorities and expose communities in order to improve their preparation and capacity to mitigate effects of volcanic eruptions on people, economy and country structure.

    The introduction of exotic species is considered as one of the major causes of biodiversity loss. The National Forest of Carajás is one of the largest mineral provinces in the world. Mining activities caused changes of the natural habitats, leaving degraded areas after the mineral exploitation. One of the mining areas within FLONA Carajás was used for the extraction of gold. In the process of exploitation, a huge depression was formed by the removal of soil which was mounded up nearby. To prevent soil erosion of these mounds, an exotic grass, Urochloa decumbens (Stapf) R.D.Webster (Poaceae) was planted. The objective of this study was to compare the impact of this non-native grass on species richness and species composition of the natural regeneration in the degraded areas. Four areas were compared, two with and two without presence of U. decumbens. In each area, twenty four 1m²/plots were established. Species richness of the regeneration areas and population sizes were significantly lower in the plots where the exotic grass was present. Our study shows that U. decumbens had a negative effect on species richness and population density, and its presence changed the species composition and distribution of life forms of the natural regeneration.

    The goal of this presentation is the description of the epidemiologic evolution and changes in natural history of the human immunodeficiency virus infection (HIV) epidemic itself and its relation with the acquired immunodeficiency syndrome-related lymphoma (ARL). We have started with the description of the world's state of the HIV epidemic, its features since the first case report in the United States of America in 1981, through the peak of new diagnoses in 1993 until the event that changed the natural history of the disease: the era of the widespread use of the highly active antiretroviral therapy (HAART), introduced in 1995 in the world and in 1997 in our country. The widespread introduction of HAART led to dramatic reductions in AIDS related mortality and morbidity throughout the developed world with a marked fall in the incidence of the major opportunistic infections in AIDS. We describe the main risk factors for the development of ARL, and the prognostic factors for survival and response to treatment. There is no clear definition in the literature of the roll that has played the use of HAART in relation to survival and response to treatment in ARL, but there is evidence that the basal count of CD4 cells has increased with HAART, leading to a better survival and response in ARL. The debate regarding this issue is surely affected by factors such as degree of antiretroviral treatment compliance, antiretroviral therapy resistance and chemotherapy heterogeneity. Finally we present the preliminary results of the analysis of our experience in ARL from 1986 to 2003.

    The use of bortezomib as a treatment modality of AHR improved and stabilized graft function (clinical response) in the majority of patients. Its use in single dose, even combined with rituximab, does not seem to be useful to obtain a sustained clinical response neither to reduce HLAabs level. The use of 4 doses of bortezomib in days 1, 4, 7, and 10 (1.3 mg/m2 BSA each) plus plasmapheresis produced both a good clinical response and a reduction in DSA. Moving forward, it will necessary to define the long-term effectiveness of bortezomib and whether rituximab administration is indispensable to achieve this goal.

    This is a retrospective study that includes four decades of kidney transplant program at our Institute, with a total of 923 kidney transplants in 872 recipients. In this report, the effect of variables in recipient, donor, and transplant on long-term graft survival was analyzed using the Kaplan Meier method with log-rank test for survival comparisons. Global graft survival at our center-analyzed by censoring for death-with-functioning-graft-for 1, 5 and 10 years was 93%, 83% and 74%, respectively, with median survival of 24.5 years. When analyzed for all-cause graft loss, 1, 5 and 10 year survival was 90%, 76% and 61%, with 12.8-year median survival. Variables associated with lower graft survival censored for death-with-functioning-graft were transplantation in an earlier decade, less histocompatibility, younger kidney transplant recipients, no induction therapy, and double drug initial immunosuppression. After Cox's regression multivariate analysis, the risk factors that remained associated with worse survival were younger recipient, earlier transplant decade, and deceased donor.

    Despite therapeutic advances, acute lymphoblastic leukemia (ALL) in adults remains a disease with poor long term outcome and survival rates. Developing countries lack of information about this disease. On the other hand, infections are frequent complications related to mortality and some research studies do not show accurate rates of septic shock or other related factors. To describe characteristics of adults with acute lymphoblastic leukemia, response to treatment, complications and to evaluate further survival related factors and to compare our experience with other reports of literature. Between September 2003 to November 2007, the entire cohort of patients with diagnosis of ALL was included. The treatment regimens used were MDACC HyperCVAD (HCVAD) and 0195 (institutional regimen). Of 40 patients included with the diagnosis of ALL, 92% was B phenotype and 8%, T phenotype, with a median age of 27 years. The median follow up was 28.5 months. Initially, 14% showed central nervous system infiltration; of 51% with available cytogenetics, 16.7% was Philadelphia chromosome positive. There were 36 patients who received treatment: 13 received HCVAD and 23 the 0195 protocol; 78% achieved global complete remission, 85% for the patients with HCVAD and 74% with 0195. The induction death rate was 2.8%. The median disease-free survival was 11.6 months (IC 95%, 2.5-20.8 months) and overall survival was 15 months (IC 95%, 10.6-19.4 months). In 95% of patients, no prophylactic antibiotic therapy was used and treatment related death was 8.4% (2.8% during induction and 5.6% during the rest of treatment). Factors associated with worse survival rate were hyperleukocytosis, T phenotype and lack of early complete remission. During induction, grade 3 to 4 non hematopoietic toxicity was 17%. Incidence of neutropenic febrile episodes was 61% and septic shock was 11%. With HCVAD, we observed worse complete remission, disease-free survival and overall survival rates compared with the original MDACC reports. Chemotherapy related death rates are similar to other early reports, despite prophylactic antibiotic was not used during myelosuppression.

    Morbid obesity is a serious health problem associated to a significant reduction in life expectancy. To evaluate the anthropometric and metabolic changes observed in obese patients, 3, 6 and 12 months after laparoscopic Roux-en-Y gastric bypass surgery and the complications associated with the procedure. Retrospective study that included 128 consecutive obese patients submitted for bariatric surgery at the INCMNSZ (2004-2006). Their mean age was 38 +/- 10 years, 83% were women with a BMI of 48 +/- 6 Kg/m2. 65% were hypertensives, 55% had hypertriglyceridemia and 34% diabetes. A year after surgery all patients had at least reduced 20% their body weight and the percentage of excess body weight loss was 73%. The prevalence of hypertension, hypertrigliceridemia and diabetes was reduced to 24%, 17% and 12%, respectively (p < 0.001). Four patients died (3%), all of them had a leak of the anastomosis and intra-abdominal abscess. One died because pulmonary embolism, another with a myocardial infarction (after surgical reinterventions) and the other two with sepsis. Laparoscopic Roux-en-Y gastric bypass surgery in morbid obese patients favors significant reductions in body weight and associated co morbidities. This surgery is not free of complications and mortality, reason why it must be done only by surgical and interdisciplinary groups with experience in these procedures.

    Acute myeloid leukemia (AML) comprises a group of diseases with different biologic characteristics; despite knowledge improvements, these are not reflected in long term survival. To describe characteristics of adults with AML in a hospital of Mexico City, their treatment response, complications and to evaluate survival related factors. Cohort study. Between January 2003 and July 2008, patients with AML diagnosis were included (except promyelocitic). Treatment protocols used: 3 + 7, high doses of cytarabine and autologous bone marrow transplant as consolidation therapy. 53 patients were included. Median age: 44 years (15-79). At diagnosis: tumor lysis syndrome in 4/ 53 (7.5%), 3/51 (5.9%) with altered liver function test and hyperleukocytosis in 8/53 (15.1%). 46 patients had available cytogenetic and this was successful in 28/46 (60.8%), 12/28 (42.8%) had adverse cytogenetic; 16/28 (57.1%) intermediate risk and none was favorable. There were 2 losses during follow up, 7 patients did not receive chemotherapy with curative intent and 1 died at diagnosis. 43 patients received 3 + 7, 13.9% died during aplasia, complete remission was achieved in 27/43 (62.7%) and 10/43 (23.2%) were refractory to treatment. A second induction attempt was required in 39.5% (17/43). Median disease free survival (DFS) was 491 days (366-615), with a median follow up of 993 days (105-1744). The median overall survival (OS) was 531 days (312-749). Aplasia related mortality decreased (p = 0.09) between the actual cohort (13.9%) and the historical cohort (37%). Long term survival in AML patients remains poor despite improvements in diagnosis, classification, and treatment. In our institution, it is required to improve induction protocols and cytogenetic analysis in order to adequately choose the group of patients that could be benefit from stem cell transplant.

Clinical characteristics and outcome among patients treated for AIDS related non-Hodgkin's Lymphoma are described. Nine patients were studied retrospectively. Overall survival (OS) and Free Disease Survival (FDS) using a Kaplan-Meier model were analyzed. Patients received (DA-EPOCH) etoposide, prednisone, vincristine, doxorubicin and cyclophosphamide. The overall Survival was 18 months and 13 month Free Disease Survival with a median follow-up of 16 months showing full response in 8/9 patients was observed. A very satisfactory treatment response in this group of patients expressed as an increased Overall Survival was noted.

    Invasive carcinoma found after simple hysterectomy for several causes is an increasing clinical condition. That situation results in the necessity for further therapy: re-operation or radiotherapy. The purpose of this review is to analyze our results with postoperative radiotherapy for these patients. In 1998, 59 patients were submitted to postoperative radiotherapy at the Oncology Hospital, Medical Cancer Center for invasive cervical cancer found after simple hysterectomy for several causes. All patients had postoperative radiotherapy, the dose depended of the magnitude of residual disease after surgery (range 10-80 Gy). After surgery 27 patients had gross residual disease; and no residual disease or microscopic disease was present in 32 patients. Three years overall survival rate was 59% for the whole group. With the results of the univariate analysis, prognostic factors found that significantly affect disease free survival were interval between hysterectomy and radiotherapy of more than 6 months, radiotherapy dose less than 50 Grays and histology. With multivariate analysis only presence of gross residual disease affect significantly disease free survival p = 0.0000. Postoperative radiotherapy results in patients with invasor cervical cancer incidentally found in hysterectomy specimens with minimal residual disease are excellent. However with the presence of more extensive residual disease the results in disease free survival are worse than those obtained in patients with similar stages who had not been treated with hysterectomy. A well established diagnostic procedure must be done in all patients candidates to simple hysterectomy.

    of glacial lakes and their hazard potential. This phase of glacial lake hazard assessment aims to be geographically comprehensive in order to identify potentially dangerous lakes that may have previously been ignored. A second phase of analysis that includes site visits will be necessary for a thorough analysis at each lake to determine the potential hazard for downstream communities. The objective of the work presented here is to identify potentially dangerous lakes that warrant further study rather than provide a final hazard assessment for each lake of the glacial lake inventory in the Cordillera Blanca.

    Objetivo: se pretende investigar la capacidad de predicción del inventario de temperamento y carácter de Cloninger (TCI-R) en la evolución de los trastornos por uso de alcohol. Metodología: Es un estudio longitudinal de 237 pacientes con trastornos por uso de alcohol, en tratamiento ambulatorio y seguimiento durante seis meses, cuya personalidad fue estudiada mediante el inventario TCI-R. Se analizó la puntuación de cada una de las dimensiones del inventario TCI-R en función de su situación (retención o abandono) al final del estudio. Resultados: La muestra presentaba puntuaciones  elevadas en búsqueda de novedad (BN) y evitación del daño (ED) y baja en autodirección (AD), definidas, estas últimas, como prominentes. El grupo que abandonó presentaba una puntuación significativamente (p= .004) más elevada en búsqueda de novedad (BN) que el grupo en seguimiento; además cuando la puntuación era superior al percentil 67 la probabilidad de abandonar era 1,07 veces superior. Conclusiones: El inventario de temperamento y carácter de Cloninger (TCI-R) es un buen instrumento para predecir la evolución de los pacientes con trastorno por uso de alcohol y la dimensión búsqueda de novedad (BN) está fuertemente relacionada con el abandono terapéutico.

    This paper presents new developments on the provenance study of lapis lazuli started by our group in 2008: during the years a multi-technique approach has been exploited to obtain minero-petrographic characterization and creation of a database considering only rock samples of known provenance. Since the final aim of the study is to develop a method to analyze archeological findings and artworks made with lapis lazuli in a completely non-invasive way, ion beam analysis techniques were employed to trace the provenance of the raw material used for the production of artifacts. Continuing this goal and focusing the analysis on determination of more significant minero-chemical markers for the provenance study of trace elements in different minerals, the method was extended with the use of micro X-ray fluorescence (µ-XRF), to test the potential of the technique for this application. The analyzes were focused on diopside and pyrite in lapis lazuli samples of known provenance (Afghanistan, Tajikistan, and Siberia). In addition, µ-XRF data were compared with micro proton-induced X-ray emission (µ-PIXE) results to verify the agreement between the two databases and to compare the analytical performance of both techniques for this application.

    An ankle/arm index < 0.90 and ≥ 1.41 is considered as abnormal. This study was aimed to investigate the prevalence of peripheral arterial disease through the identification of the ankle/arm index using Doppler ultrasound, and the possible association between pathological ankle/arm index and the micro- and macrovascular complications of diabetes and amputation. The ankle/arm index was determined in outpatient type 2 diabetic subjects. There were the following variables: age and cardiovascular outcomes. To find if the ankle/arm index is related to the cardiovascular outcomes or with the presence of micro- or macrovascular complications we determined the index of correlation of Pearson and also used logistic regression methods to analyze the association between ankle/arm index with the categorical variables. We calculated the ankle/arm index in 242 patients. The prevalence of ischemic ankle/arm index (< 0.90) was 13.6%. The Pearson correlation coefficient for ankle/arm index pathological and cardiovascular outcomes was 0.180 (p = 0.005), amputation 0.130 (p < 0.05), retinopathy 0.132 (p < 0.05), and nephropathy 0.158 (p = 0.01). In logistic regression analysis, the factors associated with pathological ankle/arm index were age > 51 years, cardiovascular outcomes, and amputation. With the Mann Whitney U test we found that a relationship exists between pathological and amputation iliotibial band (p < 0.05). Diabetic patients have a high prevalence of pathological ankle/arm index.

    In this paper we give a complete description of the power weighted inequalities, of strong, weak and restricted weak type for the pair of Riesz transforms associated with the Laguerre function system \\{mathcal{L}_k^{α}\\}, for any given α>-1. We achieve these results by a careful estimate of the kernels: near the diagonal we show that they are local Calderón-Zygmund operators while in the complement they are majorized by Hardy type operators and the maximal heat-diffusion operator. We also show that in all the cases our results are sharp.

    The aim of this study was to establish the validity and reliability of an instrument (Inventario del NIvel de Cuidados mediante IndicAdores de clasificación de Resultados de Enfermería) used to assess the dependency level in acutely hospitalised patients. This instrument is novel, and it is based on the Nursing Outcomes Classification. Multiple existing instruments for needs assessment have been poorly validated and based predominately on interventions. Standardised Nursing Languages offer an ideal framework to develop nursing sensitive instruments. A cross-sectional validation study in two acute care hospitals in Spain. This study was implemented in two phases. First, the research team developed the instrument to be validated. In the second phase, the validation process was performed by experts, and the data analysis was conducted to establish the psychometric properties of the instrument. Seven hundred and sixty-one patient ratings performed by nurses were collected during the course of the research study. Data analysis yielded a Cronbach's alpha of 0·91. An exploratory factorial analysis identified three factors (Physiological, Instrumental and Cognitive-behavioural), which explained 74% of the variance. Inventario del NIvel de Cuidados mediante IndicAdores de clasificación de Resultados de Enfermería was demonstrated to be a valid and reliable instrument based on its use in acutely hospitalised patients to assess the level of dependency. Inventario del NIvel de Cuidados mediante IndicAdores de clasificación de Resultados de Enfermería can be used as an assessment tool in hospitalised patients during the nursing process throughout the entire hospitalisation period. It contributes information to support decisions on nursing diagnoses, interventions and outcomes. It also enables data codification in large databases. © 2014 John Wiley & Sons Ltd.

    Introduccion. El uso de autoinformes sobre sintomas de mal funcionamiento en la vida diaria derivados de deficits funcionales de origen prefrontal se ha generalizado en la practica clinica, dado que permiten aportar validez ecologica incremental a otras pruebas especificas. Sin embargo, queda por determinar si la autoevaluacion es suficiente por si misma o es preferible la participacion de un evaluador externo. Sujetos y metodos. Se administro el inventario de sintomas prefrontales (ISP) a 115 sujetos en tratamiento por diversas patologias cerebrales. La misma prueba, referida al paciente, se administro a algun profesional que siguiera estrechamente la evolucion del caso y, cuando fue posible (n = 88), a un familiar o cuidador. Se exploro la bondad psicometrica del ISP en las tres muestras y se estimo el grado de correlacion y concordancia entre las tres evaluaciones. Resultados. Las tres evaluaciones mostraron correlacion significativa, aunque los pacientes declararon menos sintomas que sus familiares y cuidadores en funcionamiento ejecutivo. Las evaluaciones de familiares y pacientes se superpusieron y mostraron un alto grado de concordancia en perfil y magnitud. Conclusiones. Se recomienda, junto con la obligada evaluacion neuropsicologica, la cumplimentacion de cuestionarios o inventarios de sintomas como el ISP, con probada robustez psicometrica, que permitan explorar el impacto de las disfunciones cerebrales en el funcionamiento cotidiano. Dado que muchas de estas disfunciones se acompañan de diversos grados de anosognosia, se recomienda su administracion a observadores externos, familiares o profesionales, de cara a obtener una evaluacion mas adecuada de la magnitud de las dificultades funcionales.

    2015-12-01

    The KP province of Pakistan hosts widespread deposits of thermo-metamorphic marbles that were extensively used as a building and ornamental stones since the time of earliest flourishing civilization in this region known as Indus Valley Civilization (2500 BC). The macroscopic characteristics of 22 marble varieties collected from three different areas of Lesser Himalayas (Northwest Pakistan), its chemical, mineralogical, petrographic features, temperature conditions of metamorphic re-crystallization, and the main physical properties are presented in order to provide a solid basis for possible studies on the provenance and distribution of building stones from this region. The results provide a set of diagnostic parameters that allow discriminating the investigated marbles and quarries. Studied marbles overlap in major phase assemblage, but the accessory mineral content, chemistry, the maximum grain size (MGS) and other petrographic characteristics are particularly useful in the distinction between them. On the basis of macroscopic features, the studied marbles can be classifies into four groups: (i) white (ii) grey-to-brown veined, (iii) brown-reddish to yellowish and (iv) dark-grey to blackish veined marbles. The results show that the investigated marbles are highly heterogeneous in both their geochemical parameters and minero-petrographic features. Microscopically, the white, grey-to-brown and dark-grey to blackish marbles display homeoblastic/granoblastic texture, and the brown-reddish to yellowish marbles display a heteroblastic texture with traces of slightly deformed polysynthetic twining planes. Minero-petrography, XRD, SEM and EPMA revealed that the investigated marbles chiefly consist of calcite along with dolomite, quartz, muscovite, pyrite, K-feldspar, Mg, Ti and Fe-oxides as subordinates. The magnesium content of calcite coexisting with dolomite was estimated by both XRD and EPMA/EDS, indicating the metamorphic temperature of re-crystallization from 414

    The validity of the Fundación MacArthur Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC:PE) was examined with twenty 20- and nineteen 28-month-old, typically developing, monolingual, Spanish-speaking children living in Mexico. One measure of vocabulary (number of words) and two measures of grammar (mean of the three longest utterances and grammatical complexity score) from the IDHC:PE were compared to behavioral measures of vocabulary (number of different words from a language sample and number of objects named in a confrontation naming task) and one behavioral measure of grammar (mean length of utterance from a language sample). Only vocabulary measures were assessed in the 20-month-olds because of floor effects on the grammar measures. Results indicated validity for assessing expressive vocabulary in 20-month-olds and expressive vocabulary and grammar in 28-month-olds.

    The validity of two analogous caregiver/parent report measures of early language development in young children who are learning both English and Spanish is examined. Caregiver/parent report indices of vocabulary production and grammar were obtained for 26 children using the MacArthur Communicative Development Inventory: Words & Sentences (CDI; Fenson et al., 1994) and the Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC; Jackson-Maldonado, Bates, & Thal, 1992). Scores were significantly correlated with analogous laboratory measures in both English and Spanish, including a real-object naming task and spontaneous language use during free-play. The findings offer evidence that the CDI and IDHC provide valid assessments of early language milestones in young English- and Spanish-speaking children. Factors that may influence the validity of these tools for use with this population are also discussed.

    Introduccion. El presente trabajo explora dos cuestiones relacionadas con la aparicion de quejas subjetivas de memoria en adultos jovenes: la posibilidad de que dichas quejas sean resultado de deficits atencionales y ejecutivos, y, por otro lado, si determinadas caracteristicas de la personalidad propician y modulan la expresion clinica de las quejas. Sujetos y metodos. Se administro el Memory Everyday Failures, version española, el inventario de sintomas prefrontales y el inventario del temperamento y el caracter-revisado a una muestra de 1.132 participantes (900 de poblacion general y 232 en tratamiento por adiccion a drogas). Se exploro la correlacion entre variables de las quejas de memoria, del funcionamiento prefrontal en la vida diaria y de las dimensiones de la personalidad propuestas por Cloninger. Se estudiaron relaciones de causalidad entre las variables mediante metodos estructurales. Resultados. Se observa una fuerte correlacion entre las quejas cognitivas y la sintomatologia prefrontal, lo que sugiere que las quejas son, en realidad, resultado de una inadecuada gestion atencional y ejecutiva que propicia los errores cotidianos. Se aprecia tambien una relacion con gran tamaño del efecto entre las quejas cognitivas y la baja autodireccion. Esta dimension de la personalidad presenta una importante capacidad predictiva sobre la aparicion y la intensidad de las quejas, bien directamente, bien modulada por otras dimensiones, especialmente la evitacion del daño. Conclusiones. Los datos apoyan la idea de que las quejas de memoria son producto de la autopercepcion de fallos y errores cotidianos provocados a nivel atencional y ejecutivo –aunque son tenidos por olvidos mnesicos–, y que la expresion clinica de dichas quejas esta modulada por un perfil de la personalidad.

    Introducción: el cuidador primario enfrenta un conjunto de problemas derivados de la responsabilidad que representa cuidar al paciente; esto conlleva la generación de respuestas psicológicas complejas que actúan como mecanismos cognitivos y conductuales, conocidos como afrontamiento. El objetivo fue determinar si existía correlación entre el nivel de ansiedad y las estrategias de afrontamiento empleadas por los cuidadores primarios de pacientes en estado de postración. Métodos: estudio descriptivo, correlacional y transversal. Se aplicaron el Inventario de Ansiedad de Beck y el Inventario de Estrategias de Afrontamiento. Se utilizó el coeficiente de correlación de Spearman, un nivel de significación de 0.05 y el programa estadístico SPSS, versión 15. Resultados: se trató de 60 cuidadores primarios. La puntuación más frecuente para ansiedad fue nivel moderado (28 %). La estrategia más frecuentemente utilizada fue la resolución de problemas (media = 14.7). Al relacionar las variables se obtuvo correlación significativa con la resolución de problemas r = 0.260; la autocrítica r = 0.425; pensamiento desiderativo r = 0.412, y retirada social r = 0.453. Conclusiones: la ansiedad influye en la forma de afrontar de los cuidadores; la mayoría de la población que tiene ansiedad de moderada a severa utiliza estrategias desadaptativas enfocadas a la emoción.

  12. Characterisation and reproduction of yellow pigments used in central Italy for decorating ceramics during Renaissance

    2006-06-01

    This study presents the characterisation of prototypical yellow pigments used during the Renaissance period in Italy and the successful reproduction of homologous materials in accordance with the ancient recipes. Moreover, a large number of yellow decorative layers of Sicilian ceramic artefacts dated back from 13th to the 19th century have been selected and the main chemical, structural and minero-petrografic features have been studied by X-ray diffraction, optical microscopy and scanning electron microscopy-energy dispersive spectrometry. These results have been compared with literature data of some yellow decorations of Renaissance ceramics made in central Italy. Comparison has also been made with homologous materials that have been successfully reproduced in accordance with ancient recipes described by Cipriano Piccolpasso in the textbook: “I Tre Libri dell’Arte del Vasaio” using the same ingredients proposed by this artist. Such yellow materials reproduce the typical yellow colorants used by craftsmen of relevant sites for ceramic fabrication in central Italy, namely Città di Castello, Urbino and Castel Durante, during the 16th century. Comparative arguments have shown some intriguing differences that are indicators of both technological transfer processes between central and southern Italy as well as of some local implementations likely due to specific raw materials locally available.

    This paper is focused on archaeometric investigations of white marbles taken from the submerged archaeological site of Baia (Naples). The marine area includes the ruins of this ancient Roman city, whose structures range from luxurious maritime villas and imperial buildings with private thermae and tabernae, to more simple and modest houses. Analyses were carried out on fifty marble fragments of covering slabs, belonging to several pavements of the monumental villa, called the Villa con ingresso a protiro, in order to ascertain their provenance. The most distinctive properties of marbles are their variety of textural property especially regarding grain size (MGS), associated with the Mn content and the variation of stable isotopes. These features, supported by the contribution of other variables and studies, establish the basis for the correct identification of the marbles. For this purpose, minero-petrographic and geochemical techniques were used. Results were compared with literature data of white marbles commonly used in antiquity, especially in the Mediterranean basin and showed that a variety of precious marbles from Carrara, Docimium (Afyon), Thasos-D, Aphrodisias, Proconnesos (Marmara), Paros and Pentelicon were used in the ancient roman city of Baia, confirming the importance of the submerged archaeological site and also allowing researchers to broaden the existing database.

    Abstract Twenty-four new species of the caddisfly genus Polycentropus (Insecta: Trichoptera: Polycentropodidae) occurring in Brazil are diagnosed, described, and the male genitalia of each are illustrated. Eighteen of the new species are placed in the Polycentropus jorgenseni species complex of the Polycentropus gertschi group of New World Polycentropus sensu lato. Furthermore, 6 new species within the Polycentropus gertschi group (Polycentropus ancistrus sp. n., Polycentropus boraceia sp. n., Polycentropus carioca sp. n., Polycentropus froehlichi sp. n., Polycentropus galharada sp. n., and Polycentropus graciosa sp. n.) are placed in an informal diagnostic cluster of species with Polycentropus urubici Holzenthal and Almeida. Ten of the other Polycentropus gertschi group species form a second cluster of diagnostically similar species, the Polycentropus soniae cluster (Polycentropus caaete sp. n., Polycentropus carolae sp. n., Polycentropus cheliceratus sp. n., Polycentropus fluminensis sp. n., Polycentropus itatiaia sp. n., Polycentropus minero sp. n., Polycentropus santateresae sp. n., Polycentropus soniae sp. n., Polycentropus tripui sp. n., and Polycentropus virginiae sp. n.). Two of the remaining 8 new species are included in the Polycentropus jorgenseni species complex (Polycentropus cipoensis sp. n. and Polycentropus verruculus sp. n.), while the remaining 6 are unique and cannot be placed in one of the groups at this time (Polycentropus acinaciformis sp. n., Polycentropus amphirhamphus sp. n., Polycentropus cachoeira sp. n., Polycentropus inusitatus sp. n., Polycentropus paprockii sp. n. and Polycentropus rosalysae sp. n.).

    The type material of species of Calyptratae Diptera belonging to Anthomyiidae, Calliphoridae, Fanniidae, Muscidae, Sarcophagidae, and Tachinidae, housed in the collections of non-traditional institutions in Argentina were examined. These collections were included in the recently created "Sistema Nacional de Datos Biológicos" (National Biological Data System). We examined four collections: "Administración Nacional de Laboratorios e Institutos de Salud 'Dr. Carlos G. Malbrán'" (ANLIS), "Instituto Nacional de Tecnología Agropecuaria, Castelar, Buenos Aires" (INTA), "Instituto Argentino de Investigaciones de las Zonas Áridas" (IADIZA); and "Fundación Félix de Azara" (CFA). Comparison of the original descriptions of these species with the label information revealed the existence of 24 holotypes, 5 lectotypes, 11 syntypes, and 441 paratypes/paralectotypes. Complete information is given for each type, including reference to the original description, label data, and preservation condition.

    2013-04-01

    The ancient coastal quarries of Mediterranean are increasingly considered geosites of multidisciplinary relevance. They are sites of historical-archaeological interest that show ancient techniques of stone extraction; they are significant for cultural heritage conservation and restoration, as sources of the stones used in ancient buildings and monuments; they are sites of geological relevance, as often retain important stratigraphic sections; they are also useful markers of secular changes in the sea level. A multisciplinary study is in progress on the ancient quarries of the Sinis region (western Sardinia island), integrating archaeological, geological, minero-petrographical data. In Sardinia, coastal quarries have been established from Punic and Roman times. Many of them exploited Quaternary sediments along the southern and western coasts of the island. They consist of middle-late Pleistocene marine conglomerates and carbonate sandstones, and of coastal (aeolian) carbonate sandstones. Sandstone blocks of different sizes have been widely used in ancient cities for buildings, defensive works, harbours, etc. Three main areas of stone extraction (San Giovanni di Sinis, Punta Maimoni, Is Arutas) have been so far recognized in the Sinis. GIS-supported mapping and documentation of the sites includes their geology and stratigraphy, the extension and layout of the quarries, and an evaluation of volumes of extracted rocks. Documented archaeological evidences include ancient extraction fronts, spoil heaps, working areas, working traces in the old fronts, transport routes of blocks, and traces of loading facilities. The study is aimed at reconstructing the relationships of the quarries with the urban areas of Sinis, as the ancient Punic-Roman city of Tharros. Consequently, a minero-petrographical characterization (optical microscopy, XRD) is performed on sandstones sampled in each quarry, and in historical buildings in Tharros and other centres of the region (Cabras

  4. Characterization and provenance of the building stones from Pompeii's archaeological site (southern Italy)

    2009-04-01

    Pompeii is one of the most famous and complex areas of archaeological investigation in the world and with a uniquely favorable state of preservation. Even if many studies have been devoted in time to many archaeological aspects of this ancient city, large-scale and detailed studies aimed at characterizing mineralogy, petrography and isotope geochemistry of the building stones are still lacking. The scope of the present research is to fill this gap, pointing to the definition of the provenance of the stony materials used for ancient constructions of the city of Pompeii and to the possible trade routes. This work is part of a large-scale survey carried out by the Deutsches Archäologisches Institut of Berlin, with the purposes of reconstructing the sources of raw materials of various archaeological sites of the Sarno Plain (e.g. Longola-Poggiomarino settlement, Nuceria, Stabiae, etc.) and consequently also the paleo-environments of this area during the Olocene (Seiler, 2006, 2008; Kastemeier and Seiler, 2007). We sampled all the litotypes with different macroscopic characteristics from various buildings according to location, age (time span VI century B.C. - I century A.D.) and utilization; the architectural buildings considered for this study are mainly represented public and religious buildings, houses and funerary monuments. As possible source areas, representative litotypes have been sampled from ancient pits and outcrops surrounding Pompeii as well. A set of 80 samples have been sampled by means of micro-drillings for mineralogical, petrographic and geochemical analyses, comprising optical microscopy, X-ray diffraction, inductively coupled plasma mass, X-ray fluorescence and C-O isotope geochemistry. Minero-petrographic and XRD studies of Pompeii rock samples have shown that at least ten different litologies occur as building stones, belonging to basaltic to tephritic lavas, pyroclasts (tuffs, scoriae, etc.) and sedimentary rocks (limestone, travertines

    Introducción: uno de los orígenes de la insatisfacción de los médicos residentes está relacionado con el síndrome de burnout, el estrés y la depresión. El objetivo es describir la prevalencia y las características clínicas de los síntomas de depresión, ansiedad y riesgo de suicidio y su correlación con trastorno mental en residentes de medicina a lo largo de un año académico. Métodos: se incluyeron 108 residentes de segundo año que respondieron el inventario de depresión de Beck, el inventario de ansiedad rasgo-estado y la escala de riesgo suicida de Plutchik al inicio del ciclo académico, así como seis y doce meses después. Resultados: en la primera medición se reportó una prevalencia de 3.7 % para síntomas de depresión, 38 % para síntomas de ansiedad y 1.9 % para riesgo de suicidio; a los seis meses la prevalencia aumentó a 22.2 % para depresión, 56.5 % para ansiedad y 7.4 % para riesgo de suicidio. El análisis estadístico mostró diferencias significativas entre las tres mediciones (p < 0.001). La prevalencia de trastorno depresivo fue de 4.6 %. Casi todos los residentes que desarrollaron trastorno depresivo tenían antecedente personal de depresión. El ambiente académico y laboral tuvo poca asociación con los trastornos. Conclusiones: es recomendable la detección de residentes con vulnerabilidad a la depresión con el objeto de que reciban atención oportuna en caso de que desarrollen trastorno depresivo.
