    Sarmiento believed that Copernican astronomy was one of the critical scientific disciplines to the formation of a "modern" citizen. In this work, we shall study astronomical science from two points of view: from the scientific knowledge and the educational presentation of such knowledge. Our study will address in Argentina in 19th century, starting from the initiative of Bernardino Rivadavia in 1821, who founded an astronomic observatory at Buenos Aires, until the first activities of the observatories at Córdoba and La Plata. On both lines, scientific and educative, we shall analyze the influence of positivist ideas. We shall highlight epistemological differences between both observatories, Córdoba's based on French positivism and La Plata's based on German positivism. We shall also show the different attitude of both observatories towards education. We shall see the way in which positivist ideas had great relevance in the training of elementary school teachers. We shall also establish the relevant influence of the socio-historical context over the astronomical development, and show that astronomy was a fundamental social factor at Argentina history. Domingo F. Sarmiento consideraba que la astronomía copernicana era una de las disciplinas científicas fundamentales para la conformación de un ciudadano "moderno". En este trabajo estudiaremos la ciencia astronómica desde dos vertientes: la referida específicamente al conocimiento científico y aquella vinculada con la presentación educativa de dicho conocimiento. Nuestro estudio se desarrollará en Argentina durante el siglo XIX, desde la iniciativa de Bernardino Rivadavia en 1821, de establecer en Buenos Aires un observatorio astronómico, hasta las primeras actividades de los observatorios de Córdoba y de La Plata. En ambas vertientes, científica y educativa, analizaremos la influencia de las ideas positivistas. Resaltaremos las diferencias epistemológicas entre los dos observatorios, orientado el primero

    In this study we analyze the organization of natural science teaching within the Argentinian school context starting with teaching practices and material support in the late XIX century. By that time, school staff and teachers fostered modernization and nationalization of teaching by using collections with national issues and the foundation of museums within the schools. In particular, we examine the official debates over the mineralogical collections offered for sale by the naturalist Enrique de Carlés, and the "school museums" by professors Pedro Scalabrini and Guillermo Navarro. These account for the tension between searching for modern didactic materials associated with foreign models, and the importance of counting on elements that represented the country nature and industry.

    1986-06-01

    This discussion of Argentina covers geography, the people, history and political conditions, government, economy, foreign relations, and relations between the US and Argentina. In 1985, the population of Argentina was estimated to be 30.6 million with an estimated annual growth rate of 1.5%. The infant mortality rate is 34.1/1000, and life expectancy is 70.2 years. Argentina, which shares land borders with Bolivia, Brazil, Chile, Paraguay, and Uruguay, is bounded by the Atlantic and the Antarctic Oceans. Descendants of Italian and Spanish immigrants predominate in Argentina, but many trace their origins to British and West and East European ancestors. In recent years, there has been a substantial influx of immigrants from neighboring Latin American countries. The native Indian population, estimated to be 50,000, is concentrated in the peripheral provinces of the north, northwest, and south. What is now Argentina was discovered in 1516 by the Spanish navigator Juan de Solia. The formal declaration of independence from Spain was made on July 9, 1816. In the late 19th century, 2 forces worked to create the modern Argentine nation: the introduction of modern agricultural techniques and the integration of Argentina into the world economy. Argentina has impressive human and natural resources, but political conflict and uneven economic performance since World War II have impeded full realization of its considerable potential. Yet, it is one of the wealthiest countries in Latin America. Among the reasons for the military coup of March 1976 was the deteriorating economy, caused by declining production and rampant inflation. Under the leadership of the Minister of the Economy, the military government focused attention on those immediate problems, and, in 1978, embarked on a new development strategy focusing on the establishment of a free market economy. There was little improvement in the economy, and a new economic plan was introduced in 1985 which has capped inflation by

    Background notes on Argentina provide a profile of the geography, selected demographic features, government and economic conditions. Descriptive text includes a discussion of the people, their history and political conditions, the government and officials, the state of the economy, their defense, foreign relations, and relations with the US. The 1992 estimated population was about 33 million of whom 97% are European (mostly Spanish and Italian). Religions represented are Roman Catholic (92%), Protestant (2%), Jewish (2%), and other (4%). Adult literacy is 95%. 36% are engaged in industry and commerce, 20% in services, 19% in agriculture, 6% in transport and communications, and 19% other. Per capita gross domestic product was $4,500. There are only 50,000 native Indians remaining in peripheral provinces. The population enjoys a high standard of living and a low growth rate. The country was shaped by dominant forces: modern agricultural techniques and the integration of the country into the world economy. Foreign investment aided the economic revolution. Conservative and radical rule has swung the country back and forth politically since 1916. Colonel Juan Domingo Peron led a successful military coup in 1943 and was elected in 1946. Policies were instituted to give a greater voice to the working class, and with the influences of his wife, women's groups. In 1955, he was ousted by the military, which failed to revive the economy and quiet increasing terrorism. After a number of difficult elections, Peron was reinstated as president in 1973. Extremists on the left and right threatened public order; the military as a consequence imprisoned persons indefinitely. Peron's wife succeeded him after his death, but was removed from office in the military coup of 1976. Basic human rights were violated during this period. By 1983, a fair election was held and support increased for a democratic system. In 1989, Carlos Saul Menem, a Peronist candidate, won and established

    This volume contains selected papers which have been presented at the XIX Latin American Symposium on Solid State Physics (SLAFES XIX) held at Puerto Iguazú, Argentina, from 5--10 October 2008. The conference, covering all areas of Solid State Physics, is one of the most important and traditional meetings in Physics in our region. The Latin American Symposium on Solid State Physics is a forum where researchers and students from Latin America as well as leading scientists from other parts of the world get together to exchange information, strengthen collaborations and identify new challenges in Solid State Physics. This successful series of meetings has been organised in eight different countries, the last three held in Mérida, Venezuela (2002), La Habana, Cuba (2004) and Puebla, México (2006). Following the trends of previous events, SLAFES XIX included seven plenary talks, eighteen invited talks and contributions, and 28 oral and 255 poster presentations, covering mostly the latest experimental and theoretical advances in Nanophysics, Nanomaterials and Nanotechnology, Spintronics, Magnetism, New Materials, Superconductivity, Surfaces and Interfaces, Low-Dimensional Systems, Materials Preparation and Characterization, Theory and Computing Simulations of Materials among other topics. The group of scientists participating had come from Argentina, Chile, Colombia, Cuba, Brazil, France, Spain, Switzerland and the USA We are indebted to all participants for their enthusiasm and contributions and to the members of the International Advisory Commitees.

    In 1987 Argentina had a population of 31.5 million, with an annual rate of increase of 1.6%. The total fertility rate was 3.3, and the birth rate was 24/1000 population. Mortality stood at 8/1000 population, and the infant mortality rate was 35.3/1000 live births. Life expectancy at birth is 70 years. 84% of the population lives in Argentina's urban areas. Current government policies call for regional development to maintain and increase population in rural areas and control growth in urban centers. 90% of the population is of European descent, largely as a result of high rates of immigration during the 1880s-1930s from countries such as Spain and Italy. In 1985 the gross national product per capita was US$2130. Argentina is rich in resources and almost self-sufficient in terms of basic foodstuffs, power supply, and advanced communication networks. On the other hand, political conflicts and economic crises have hindered the realization of both human and natural resource potential. 80% of the value of export products is the amount due in interest on foreign debts.

  10. Electron Impact Excitation Of Ti XIX

    Aggarwal, Kanti M.; Keenan, F. P.

    2012-05-01

    Emission lines of Ti XIX are important for the modeling and diagnostics of lasing, fusion and astrophysical plasmas, for which atomic data are required for a variety of parameters, such as energy levels, radiative rates (A- values), and excitation rates or equivalently the effective collision strengths (Υ), which are obtained from the electron impact collision strengths (Ω). Experimentally, energy levels are available for Ti XIX on the NIST website, but there is paucity for accurate collisional atomic data. Therefore, here we report a complete set of results (namely energy levels, radiative rates, and effective collision strengths) for all transitions among the lowest 98 levels of Ti XIX. These levels belong to the (1s2) 2s2, 2s2p, 2p2, 2s3l, 2p3l, 2s4l, and 2p4l configurations. Finally, we also report the A- values for four types of transitions, namely electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2), because these are also required for plasma modeling. For our calculations of wavefunctions, we have adopted the fully relativistic GRASP code, and for the calculations of Ω, the Dirac atomic R-matrix code (DARC) of PH Norrington and IP Grant. Additionally, parallel calculations have also been performed with the Flexible Atomic Code (FAC) of Gu, so that all atomic parameters can be rigorously assessed for accuracy.

    2003-09-01

    ICO XIX was the 19th in a series of triennial congresses promoted by the International Commission for Optics (ICO) and held in conjunction with the general assembly of the organization. ICO is an affiliated commission of the International Union of Pure and Applied Physics (IUPAP), and was created in 1947 with the object of contributing on an international basis to the progress and diffusion of knowledge in optics. ICO I, the first official congress held in Delft (The Netherlands) in July 1948, saw the participation of 44 delegates from 11 countries. ICO XIX, held in Florence (Italy) in August 2002, was attended by more than 400 participants from most of the 43 Territorial Committees which are current members of ICO. The triennial congress moves quite regularly from one continent to another; thus, the previous one (ICO XVIII) was held in San Francisco (USA) in 1999, and the next one (ICO XX) will be held in Changchun, a city in northern China, in 2005. Optics is growing up fast and healthily. To quote John N Howard, founding editor of Applied Optics, 'Optics is almost unique in being both a field of challenging scientific study and also an important tool that can be applied to many other fields of science and technology.' A confirmation of that comes from the results of a poll on the most beautiful physics experiment, published in Physics World in September 2002. The top place was awarded to the application of Young's double-slit experiment to the interference of single electrons (demonstrated by C Jonsson in 1961), while two 'pure' optical experiments ranked 4th and 5th—respectively, Newton's decomposition of sunlight with a prism (which dates back to around 1665) and Young's original light interference experiment (around 1801). Similarly, if we look to the years since the founding of the ICO, many of the Nobel Prizes in physics have been awarded for works in optics and spectroscopy, including, to mention just a few winners, Zernike and Gabor in image formation

  14. Linkage Group Xix of Chlamydomonas Reinhardtii Has a Linear Map

    1993-01-01

    Linkage group XIX (or the UNI linkage group) of Chlamydomonas reinhardtii has been reported to show a circular meiotic recombination map. A circular map predicts the existence of strong chiasma and chromatid interference, which would lead to an excess number of two-strand double crossovers during meiosis. We have tested this prediction in multipoint crosses. Our results are consistent with a linear linkage group that shows positive chiasma interference and no chromatid interference. Chiasma interference occurs both within arms and across the centromere. Of the original loci that contributed to the circular map, we find that two map to other linkage groups and a third cannot be retested because the mutant strain that defined it has been lost. A second reported unusual property for linkage group XIX was the increase in meiotic recombination with increases in temperature during a period that precedes the onset of meiosis. Although we observed changes in recombination frequencies in some intervals on linkage group XIX in crosses to CC-1952, and in strains heterozygous for the mutation ger1 at 16°, we also show that our strains do not exhibit the previously observed patterns of temperature-sensitive recombination for two different pairs of loci on linkage group XIX. We conclude that linkage group XIX has a linear genetic map that is not significantly different from other Chlamydomonas linkage groups. PMID:8462847

    In 1997, Argentina gave priority to asbestos in its National Plan for the Sound Management of Chemicals, and it was the subject of a Technical Task Force on Occupational Cancer. After five years of public hearings in which government, workers, industry advocates, environmentalists, clinicians, scientists, and consumers participated, it was agreed that asbestos exposure is a risk factor for both workers and the general population, and that Argentina should provide to its people the same protections adopted by many developed countries. Pressure from asbestos industry groups initially delayed the inclusion of chrysotile asbestos in the proposed ban, but on January 1, 2003, the mining and import of all forms of asbestos were banned in Argentina.

    The deregulation and privatization of major Argentine industries has set off a boom in the oil industry, which is now open from exploration and production through basic petrochemicals and beyond, to anyone from anywhere. The quest for greater efficiency and application of advanced technology is now the order of the day. The author reports that Argentina is like a new world compared to the country he visited during assignments there in 1987 and 1991. What hasn't changed, his following articles show, is that YPF, the former state company, is still the dominant player though it has sold off billions in assets. The three articles in this special report are: privatization of state company catalyzes Argentina oil industry; YPF refineries aiming for world class operations; and YPF launches diverse attack in pursuit of production.

    Five models based on multiple regression were developed to estimate wheat yields for the five wheat growing provinces of Argentina. Meteorological data sets were obtained for each province by averaging data for stations within each province. Predictor variables for the models were derived from monthly total precipitation, average monthly mean temperature, and average monthly maximum temperature. Buenos Aires was the only province for which a trend variable was included because of increasing trend in yield due to technology from 1950 to 1963.

    A significant increase in the number of isolations of Salmonella enteritidis has been observed in Argentina since 1986. Outbreaks of foodborne diseases in humans were associated with the consumption of raw or undercooked hens' eggs. Between 1986 and the first 6 months of 1993 there were 150 outbreaks reported, affecting more than 6000 persons. A total of 71.3% of these outbreaks were confirmed by stool cultures, and 47.3% by bacteriological study of the food implicated in the outbreak. A permanent surveillance of salmonellosis is imperative, taking into account the persistence of Salmonella enteritidis isolations in sporadic cases and in new outbreaks.

    2017-10-01

    QUBIC (QU Bolometric Interferometer for Cosmology) is an experimental cosmology project to measure the modes in the polarization of the cosmic background radiation (CBR), the fossil relic that reveals the properties at the Universe 380,000 years after the Planck Era. Discovery of the CBR in 1964 and measurement of tiny temperature anisotropies in 1992 were major breakthroughs in our understanding of the Universe. The next challenge is to measure the polarization of the CBR accurately enough to detect modes that would reveal the existence of primordial gravitational waves produced in the first stages of the Planck Era and probe inflation theory, that assumes an accelerated expansion during the first seconds. The mode signal is however extremely weak and its measurement requires complex instruments. The QUBIC collaboration has developed the concept of interferometric bolometry, that brings together the sensitivity of bolometric detectors with the control of systematic effects provided by interferometry. QUBIC is an international collaboration involving several universities and laboratories in France, Italy, United Kingdom and USA. Recently, Argentina has suggested Alto Chorrillo (Salta), as candidate site for the installation of the experiment, next to the LLAMA site. Here we describe the scientific objectives and the main features of the experiment and we detail the process through which the international collaboration decided to install in Argentina its first module as well as the challenges for our country in this project.

  18. NORM survey in Argentina.

    PubMed

    Canoba, A C

    2012-01-01

    A survey programme was initiated several years ago with the aim of estimating the incidence of naturally occurring radioactive material (NORM) exposure for workers in the oil and gas industry, gold mining, spas, and a tourist cavern in Argentina. This work presents the procedures, methods employed, and results to date from the survey, including protection and remedial actions recommended when deemed necessary. Radium isotope concentrations measured in some samples were well above the exemption values established by IAEA Standards. Elevated radon levels (above the action level established for workplaces) were detected in the gas facilities, the gold mine, and the tourist cavern. The pertinent authorities and the facilities were informed of the detected values in order to take actions to reduce concentrations. In terms of the spas, almost all values for geothermal waters were below the corresponding guidance levels. Some regulatory aspects for the management of NORM are suggested. Copyright © 2012.

  19. Collagen XIX is expressed by interneurons and contributes to the formation of hippocampal synapses.

    Extracellular matrix (ECM) molecules contribute to the formation and maintenance of synapses in the mammalian nervous system. We previously discovered a family of nonfibrillar collagens that organize synaptic differentiation at the neuromuscular junction (NMJ). Although many NMJ-organizing cues contribute to central nervous system (CNS) synaptogenesis, whether similar roles for collagens exist at central synapses remained unclear. In the present study we discovered that col19a1, the gene encoding nonfibrillar collagen XIX, is expressed by subsets of hippocampal neurons. Colocalization with the interneuron-specific enzyme glutamate decarboxylase 67 (Gad67), but not other cell-type-specific markers, suggests that hippocampal expression of col19a1 is restricted to interneurons. However, not all hippocampal interneurons express col19a1 mRNA; subsets of neuropeptide Y (NPY)-, somatostatin (Som)-, and calbindin (Calb)-immunoreactive interneurons express col19a1, but those containing parvalbumin (Parv) or calretinin (Calr) do not. To assess whether collagen XIX is required for the normal formation of hippocampal synapses, we examined synaptic morphology and composition in targeted mouse mutants lacking collagen XIX. We show here that subsets of synaptotagmin 2 (Syt2)-containing hippocampal nerve terminals appear malformed in the absence of collagen XIX. The presence of Syt2 in inhibitory hippocampal synapses, the altered distribution of Gad67 in collagen XIX-deficient subiculum, and abnormal levels of gephyrin in collagen XIX-deficient hippocampal extracts all suggest inhibitory synapses are affected by the loss of collagen XIX. Together, these data not only reveal that collagen XIX is expressed by central neurons, but show for the first time that a nonfibrillar collagen is necessary for the formation of hippocampal synapses.

  20. The NC1 domain of type XIX collagen inhibits in vivo melanoma growth.

    Type XIX collagen is a minor collagen that localizes to basement membrane zones, together with types IV, XV, and XVIII collagens. Because several NC1 COOH-terminal domains of other chains from basement membrane collagens were reported to exhibit antitumor activity, we decided to study the effects of the NC1(XIX) collagen domain on tumor progression using an experimental in vivo model of mouse melanoma. We observed a 70% reduction in tumor volume in NC1(XIX)-treated mice compared with the corresponding controls. Histologic examination of the tumors showed a strong decrease in tumor vascularization in treated mice. In vitro, NC1(XIX) inhibited the migrating capacity of tumor cells and their capacity to invade Matrigel. It also inhibited the capacity of human microvascular endothelial cells to form pseudotubes in Matrigel. This effect was accompanied by a strong inhibition of membrane type-1 matrix metalloproteinase (matrix metalloproteinase-14) and vascular endothelial growth factor expression. Collectively, our data indicate that the NC1 domain of type XIX collagen exerts antitumor activity. This effect is mediated by a strong inhibition of the invasive capacities of tumor cells and antiangiogenic effects. NC1(XIX) should now be considered as a new member of the basement membrane collagen-derived matrikine family with antitumor and antiangiogenic activity.

Note the yellowish sediment from the Parana River mixing with the redish sediment from the Uruguay River as it empties into the Rio de la Plata. The water level of the Parana seems high, which could explain the high sediment discharge. A variety of land surface features are visible in this image. To the north, the greenish pixels show forest regions, as well as characteristic clusters of rectangular patterns of agricultural fields. In the lower left of the image, the lighter green pixels show arable regions where there is grazing and farming. (Image courtesy Jacques Descloitres, MODIS Land Group, NASA GSFC)

    Argentina is actively seeking private capital and expertise from around the world. The objective is energy self-sufficiency by 1982 by bringing $5 billion of private investment to bear on exploration and production projects. This year, the government is launching a program aimed at medium-to-large independent US oil companies. Enhanced recovery technology from the US companies is to be coupled with Argentine capital and used on fields for which Argentina has neither the manpower nor the money to work. Onshore and offshore risk contracts are also available. The exploration results and production potential of 5 basins (San Jorge Gulf, Neuquen, Cuyana, Austral, and Northeast) are explained.

    Atomic data including energy levels, gf-values, and wavelengths are given for the Fe XIX transitions that give rise to lines in solar-flare and active-region X-ray spectra. Collision strengths and theoretical intensity ratios are presented for lines which occur in the 13.2-14.3-A range. Observed spectra are found to be consistent with those derived from the present Fe XIX atomic data. For the case of spectra in which the Fe XIX lines are very strong, such as those at the maxima of hot flares, two observed line features due to Fe XIX are shown to have larger intensities than calculated. The calculated Fe XIX and Ne IX line spectra are used to determine electron densities from Ne IX line ratios.

  9. Stereo Pair: Patagonia, Argentina

    This view of northern Patagonia, near El Cain, Argentina shows complexly eroded volcanic terrain, with basalt mesas, sinkholes, landslide debris, playas, and relatively few integrated drainage channels. Surrounding this site (but also extending far to the east) is a broad plateau capped by basalt, the Meseta de Somuncura. Here, near the western edge of the plateau, erosion has broken through the basalt cap in a variety of ways. On the mesas, water-filled sinkholes (lower left) are most likely the result of the collapse of old lava tubes. Along the edges of the mesas (several locations) the basalt seems to be sliding away from the plateau in a series of slices. Water erosion by overland flow is also evident, particularly in canyons where vegetation blankets the drainage channels (green patterns, bottom of image). However, overland water flow does not extend very far at any location. This entire site drains to local playas, some of which are seen here (blue). While the water can reach the playas and then evaporate, what becomes of the eroded rock debris? Wind might excavate some of the finer eroded debris, but the fate of much of the missing bedrock remains mysterious.

    This cross-eyed stereoscopic image pair was generated using topographic data from the Shuttle Radar Topography Mission, combined with an enhanced Landsat 7 satellite color image. The topography data are used to create two differing perspectives of a single image, one perspective for each eye. In doing so, each point in the image is shifted slightly, depending on its elevation. When stereoscopically merged, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions.

    This view of northern Patagonia, at Los Menucos, Argentina shows remnants of relatively young volcanoes built upon an eroded plain of much older and contorted volcanic, granitic, and sedimentary rocks. The large purple, brown, and green 'butterfly' pattern is a single volcano that has been deeply eroded. Large holes on the volcano's flanks indicate that they may have collapsed soon after eruption, as fluid molten rock drained out from under its cooled and solidified outer shell. At the upper left, a more recent eruption occurred and produced a small volcanic cone and a long stream of lava, which flowed down a gully. At the top of the image, volcanic intrusions permeated the older rocks resulting in a chain of small dark volcanic peaks. At the top center of the image, two halves of a tan ellipse pattern are offset from each other. This feature is an old igneous intrusion that has been split by a right-lateral fault. The apparent offset is about 6.6 kilometers (4 miles). Color, tonal, and topographic discontinuities reveal the fault trace as it extends across the image to the lower left. However, young unbroken basalt flows show that the fault has not been active recently.

    The political process that led to the important agreements reached between Argentina and Brazil to guarantee that nuclear energy is used in both countries exclusively for peaceful purposes could prove to be a useful model. These achievements are due primarily to the return of democratic rule in both countries. While the political processes leading to fully integrated democratic institutions may not have taken hold as fully in other regions of proliferation concern, the Argentine-Brazilian agreements suggest that similar regional safeguards arrangements might be possible in South Asia, on the Korean Peninsula eventually, and perhaps in portions of the Middle East. These agreements include the creation of the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC) for the application of safeguards to both countries; and the Quadripartite Agreement between Brazil, Argentina, the International Atomic Energy Agency (IAEA) and ABACC.

    We present B, V time-series photometry of Andromeda XIX (And XIX), the most extended (half-light radius of 6.'2) of Andromeda's dwarf spheroidal companions, which we observed with the Large Binocular Cameras at the Large Binocular Telescope. We surveyed a 23' × 23' area centered on And XIX and present the deepest color-magnitude diagram (CMD) ever obtained for this galaxy, reaching, at V ∼ 26.3 mag, about one magnitude below the horizontal branch (HB). The CMD shows a prominent and slightly widened red giant branch, along with a predominantly red HB, which extends to the blue to significantly populate the classical instability strip. We have identified 39 pulsating variable stars, of which 31 are of RR Lyrae type and 8 are Anomalous Cepheids (ACs). Twelve of the RR Lyrae variables and three of the ACs are located within And XIX's half light radius. The average period of the fundamental mode RR Lyrae stars ((P {sub ab}) = 0.62 days, σ = 0.03 days) and the period-amplitude diagram qualify And XIX as an Oosterhoff-Intermediate system. From the average luminosity of the RR Lyrae stars ((V(RR)) = 25.34 mag, σ = 0.10 mag), we determine a distance modulus of (m – M){sub 0} = 24.52 ± 0.23 mag in a scale where the distance to the Large Magellanic Cloud (LMC) is 18.5 ± 0.1 mag.

  9. [The health system of Argentina].

    PubMed

    Belló, Mariana; Becerril-Montekio, Victor M

    2011-01-01

    This paper describes the health system of Argentina.This system has three sectors: public, social security and private.The public sector includes the national and provincial ministries as well as the network of public hospitals and primary health care units which provide care to the poor and uninsured population. This sector is financed with taxes and payments made by social security beneficiaries that use public health care facilities. The social security sector or Obras Sociales (OS) covers all workers of the formal economy and their families. Most OS operate through contracts with private providers and are financed with payroll contributions of employers and employees. Finally, the private sector includes all those private providers offering services to individuals, OS beneficiaries and all those with private health insurance.This sector also includes private insurance agencies called Prepaid Medicine Enterprises, financed mostly through premiums paid by families and/or employers.This paper also discusses some of the recent innovations implemented in Argentina, including the program Remediar.

  10. Education in acoustics in Argentina

    NASA Astrophysics Data System (ADS)

    Miyara, Federico

    2002-11-01

    Over the last decades, education in acoustics (EA) in Argentina has experienced ups and downs due to economic and political issues interfering with long term projects. Unlike other countries, like Chile, where EA has reached maturity in spite of the acoustical industry having shown little development, Argentina has several well-established manufacturers of acoustic materials and equipment but no specific career with a major in acoustics. At the university level, acoustics is taught as a complementary--often elective--course for careers such as architecture, communication engineering, or music. In spite of this there are several research centers with programs covering environmental and community noise, effects of noise on man, acoustic signal processing, musical acoustics and acoustic emission, and several national and international meetings are held each year in which results are communicated and discussed. Several books on a variety of topics such as sound system, architectural acoustics, and noise control have been published as well. Another chapter in EA is technical and vocational education, ranging between secondary and postsecondary levels, with technical training on sound system operation or design. Over the last years there have been several attempts to implement master degrees in acoustics or audio engineering, with little or no success.

  11. Loss of Interneuron-Derived Collagen XIX Leads to a Reduction in Perineuronal Nets in the Mammalian Telencephalon.

    PubMed

    Su, Jianmin; Cole, James; Fox, Michael A

    2017-02-01

    Perineuronal nets (PNNs) are lattice-like supramolecular assemblies of extracellular glycoproteins that surround subsets of neuronal cell bodies in the mammalian telencephalon. PNNs emerge at the end of the critical period of brain development, limit neuronal plasticity in the adult brain, and are lost in a variety of complex brain disorders diseases, including schizophrenia. The link between PNNs and schizophrenia led us to question whether neuronally expressed extracellular matrix (ECM) molecules associated with schizophrenia contribute to the assembly of these specialized supramolecular ECM assemblies. We focused on collagen XIX-a minor, nonfibrillar collagen expressed by subsets of telencephalic interneurons. Genetic alterations in the region encoding collagen XIX have been associated with familial schizophrenia, and loss of this collagen in mice results in altered inhibitory synapses, seizures, and the acquisition of schizophrenia-related behaviors. Here, we demonstrate that loss of collagen XIX also results in a reduction of telencephalic PNNs. Loss of PNNs was accompanied with reduced levels of aggrecan (Acan), a major component of PNNs. Despite reduced levels of PNN constituents in collagen XIX-deficient mice ( col19a1(-)(/)(-)), we failed to detect reduced expression of genes encoding these ECM molecules. Instead, we discovered a widespread upregulation of extracellular proteases capable of cleaving Acan and other PNN constituents in col19a1(-)(/)(-) brains. Taken together, these results suggest a mechanism by which the loss of collagen XIX speeds PNN degradation and they identify a novel mechanism by which the loss of collagen XIX may contribute to complex brain disorders.

  12. Comparison of Fe XVIII and Fe XIX Line Emissions with Spectral Models

    We discuss here the observations of Fe XVIII and XIX emission lines and compare the X-ray, EUV and FUV lines with the spectral codes widely used today (e.g. FAC and APEC). We assess the relative accuracy of these spectral models and try to identify the critical atomic data and processes. Capella with a narrow enhancement in its emission measure distribution at 6 MK provides a unique opportunity to test the Fe XVIII and Fe XIX model emissivities which peak from 6 to 8 MK. We use the summed spectra from Chandra HETG/ACIS-S and LETG/HRC-S, as well as contemporaneous EUVE and FUSE observations, to measure line ratios for comparison with predictions.

  13. Novel Coronal Temperature Determination using the Fe XVIII and Fe XIX lines observed with the HETGS

    NASA Astrophysics Data System (ADS)

    Beiersdorfer, Peter

    2010-09-01

    We propose to determine the temperature of the coronal regions responsible for the Fe XVIII and Fe XIX emission using dielectronic recombination satellite lines. These lines are weak, but can be observed in the co-added HEG or MEG spectra of Capella. The results will be compared to the temperature derived from the differential emission measure, providing a much needed test of the underlying charge fraction calculations. Our analysis also addresses the recent discovery that the Fe XVIII and Fe XIX flux near 10 A does not match the flux near 100 A nor 1000 A observed with EUVE/FUSE, casting doubt on the HETGS calibration, atomic data, and inferred temperatures. Our work will open up a new way of determining the temperature, which can be applied in the future to the analysis of other coronae.

  4. Low-power XiX decoupling in MAS NMR experiments.

    PubMed

    Ernst, Matthias; Samoson, Ago; Meier, Beat H

    2003-08-01

    Low-power XiX proton decoupling under fast magic-angle spinning is introduced. The method is applicable if the MAS frequency exceeds the proton-proton interactions. For rigid organic solids this is the case for MAS frequencies above approximately 40 kHz. It is shown that the quality of the decoupling as well as the sensitivity to frequency offsets can be improved compared to low-power continuous-wave decoupling. The decoupling efficiency is somewhat reduced compared to optimized high-power decoupling: in a peptide sample investigated at an MAS frequency of 50 kHz a loss of about 10% in signal intensity for CH3 and CH groups, and of about 40% for CH2 groups was observed. Taking into consideration, that the rf amplitude in the low-power XiX was about 15 times lower than in high-power XiX decoupling, such a reduction in line intensity is sometimes tolerable.

  9. Pervasive faint Fe XIX emission from a solar active region observed with EUNIS-13: Evidence for nanoflare heating

    SciTech Connect

    Brosius, Jeffrey W.; Daw, Adrian N.; Rabin, D. M.

    2014-08-01

    We present spatially resolved EUV spectroscopic measurements of pervasive, faint Fe XIX 592.2 Å line emission in an active region observed during the 2013 April 23 flight of the Extreme Ultraviolet Normal Incidence Spectrograph (EUNIS-13) sounding rocket instrument. With cooled detectors, high sensitivity, and high spectral resolution, EUNIS-13 resolves the lines of Fe XIX at 592.2 Å (formed at temperature T ≈ 8.9 MK) and Fe XII at 592.6 Å (T ≈ 1.6 MK). The Fe XIX line emission, observed over an area in excess of 4920 arcsec{sup 2} (2.58 × 10{sup 9} km{sup 2}, more than 60% of the active region), provides strong evidence for the nanoflare heating model of the solar corona. No GOES events occurred in the region less than 2 hr before the rocket flight, but a microflare was observed north and east of the region with RHESSI and EUNIS during the flight. The absence of significant upward velocities anywhere in the region, particularly the microflare, indicates that the pervasive Fe XIX emission is not propelled outward from the microflare site, but is most likely attributed to localized heating (not necessarily due to reconnection) consistent with the nanoflare heating model of the solar corona. Assuming ionization equilibrium we estimate Fe XIX/Fe XII emission measure ratios of ∼0.076 just outside the AR core and ∼0.59 in the core.

    The paper will review the exploration activities in Argentina, but slightly departing from the technical-geological viewpoints which have been dealt with in a number of previous congresses and symposiums. The talk will cover Argentine geological basins, exploration history in each of them, a brief outline of their stratigraphic columns and producing formations, highlighting their original and remaining hydrocarbon reserves. Based on the history of the exploratory discoveries, and what has been learned from them, a forecast will be made of the necessary effort to recover the reserves that is estimated will be consumed up to the year 2000. The results obtained from the four rounds of bids for the exploration of the 165 areas under the so-called Houston Plan, will be extensively discussed and its principal clauses will be underlined. A special emphasis will be given to the Gas Exploration issue, summarizing its short history and the essential role that this fluid will play in the Argentine energy balance of the future.

    In XIX century the modern hospital develops because of and by means of the scientific revolution in medicine, and, in particular, in clinics. In the new hospital the hippocratic praxis and the models of experimental medicine combine, together with mechanistic epistemology and the new general theory of illness, health and disease. The new medicine, founding on an anthropological view of life and death, links with a renewed political attention towards social events; the new idea of health proposes a new model for hospitalization in which doctores and manuales (specialists in surgery) meet. In Italy, the evolution of the hospital tipology develops through the century.

    A so-called XUV excess has been suspected with the relative fluxes of Fe XVIII and Fe XIX lines observed in the XUV and EUV ranges of the spectrum of the star Capella as observed by the Chandra spacecraft, even after correction for interstellar absorption. This excess becomes apparent in the comparison of the observations with simulations of stellar spectra obtained using collisional-radiative models that employ, for example, the Atomic Plasma Emission Code (APEC) or the Flexible Atomic Code (FAC). We have addressed this problem by laboratory studies using the Livermore electron beam ion trap (EBIT).

    Adikes, Rebecca C; Unrath, William C; Yengo, Christopher M; Quintero, Omar A

    2013-05-01

    Mitochondrial dynamics are dependent on both the microtubule and actin cytoskeletal systems. Evidence for the involvement of myosin motors has been described in many systems, and until recently a candidate mitochondrial myosin transport motor had not been described in vertebrates. Myosin-XIX (MYO19) was predicted to represent a novel class of myosin and had previously been shown to bind to mitochondria and increase mitochondrial network dynamics when ectopically expressed. Our analyses comparing ∼40 MYO19 orthologs to ∼2000 other myosin motor domain sequences identified instances of homology well-conserved within class XIX myosins that were not found in other myosin classes, suggesting MYO19-specific mechanochemistry. Steady-state biochemical analyses of the MYO19 motor domain indicate that Homo sapiens MYO19 is a functional motor. Insect cell-expressed constructs bound calmodulin as a light chain at the predicted stoichiometry and displayed actin-activated ATPase activity. MYO19 constructs demonstrated high actin affinity in the presence of ATP in actin-co-sedimentation assays, and translocated actin filaments in gliding assays. Expression of GFP-MYO19 containing a mutation impairing ATPase activity did not enhance mitochondrial network dynamics, as occurs with wild-type MYO19, indicating that myosin motor activity is required for mitochondrial motility. The measured biochemical properties of MYO19 suggest it is a high-duty ratio motor that could serve to transport mitochondria or anchor mitochondria, depending upon the cellular microenvironment.

    Objective To evaluate the processes and outcomes of tobacco litigation in Argentina and to analyse the strategies of the tobacco industry to oppose litigation using tobacco industry documents. Methods A systematic search of tobacco industry documents on the internet dating from 1978 to 2002. Law library searches using Argentinean official and unofficial reports systems were combined with computerised online searches. Results There have been at least 15 failed litigation cases in Argentina and the tobacco industry presented a concerted defence in every claim regardless of cost. We categorised 11 cases as product liability and nicotine addiction, two as health care reimbursement, and two as criminal law and secondhand smoke.

    To evaluate the processes and outcomes of tobacco litigation in Argentina and to analyse the strategies of the tobacco industry to oppose litigation using tobacco industry documents. A systematic search of tobacco industry documents on the internet dating from 1978 to 2002. Law library searches using Argentinean official and unofficial reports systems were combined with computerised online searches. There have been at least 15 failed litigation cases in Argentina and the tobacco industry presented a concerted defence in every claim regardless of cost. We categorised 11 cases as product liability and nicotine addiction, two as health care reimbursement, and two as criminal law and secondhand smoke. Industry strategies included hiring legal consultants from prestigious international and Argentinean law firms and developing litigation prevention programmes. Industry monitored legal academic meetings, controlled the development of new product liability legislation, obtained favourable opinions from experts, and closely observed the development of litigation in Argentina. The strategies used by the industry have been successful in preventing recovery for tobacco injuries through litigation.

  17. SRTM Anaglyph: Lava plateaus, Argentina

    NASA Technical Reports Server (NTRS)

    2001-01-01

    All of the major landforms relate to volcanism and/or erosion in this Shuttle Radar Topography Mission scene of Patagonia, near La Esperanza, Argentina. The two prominent plateaus once formed a continuous surface that extended over much of this region. Younger volcanoes have grown through and atop the plateau, and one just south of this scene has sent a long, narrow flow down a stream channel (lower left). The topographic pattern shows that streams dominate the erosion processes in this arid environment even though wind is known to move substantial amounts of sediment here.

    This anaglyph was produced by first shading a preliminary SRTM elevation model. The stereoscopic effect was then created by generating two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter.

    Elevation data used in this image was acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC.

    2001-01-01

    Topographic data provided by the Shuttle Radar Topography Mission can provide many clues to geologic history and processes. This view of an area southwest of Zapala, Argentina, shows a wide diversity of geologic features. The highest peaks (left) appear to be massive (un-layered)crystalline rocks, perhaps granites. To their right (eastward) are tilted and eroded layered rocks, perhaps old lava flows, forming prominent ridges. Farther east and south, more subtle and curvilinear ridges show that the rock layers have not only been tilted but also folded. At the upper right, plateaus that cap the underlying geologic complexities are more recent lava flows -younger than the folding, but older than the current erosional pattern. Landforms in the southeast (lower right) and south-central areas appear partially wind sculpted.

    The interplay of volcanism, stream erosion and landslides is evident in this Shuttle Radar Topography Mission view of the eastern flank of the Andes Mountains, southeast of San Carlos de Bariloche, Argentina. Older lava flows emanating from the Andes once covered much of this area. Younger, local volcanoes (seen here as small peaks) then covered parts of the area with fresh, erosion resistant flows (seen here as very smooth surfaces). Subsequent erosion has created fine patterns on the older surfaces (bottom of the image) and bolder, irregular patterns through and around the younger surfaces (upper center and right center). Meanwhile, where a large stream immediately borders the resistant plateau (center of the image), lateral erosion has undercut the resistant plateau causing slivers of it to fall into the stream channel. This scene well illustrate show topographic data alone can reveal some aspects of recent geologic history.

  1. Loss of Interneuron-Derived Collagen XIX Leads to a Reduction in Perineuronal Nets in the Mammalian Telencephalon

    PubMed Central

    Su, Jianmin; Cole, James

    2017-01-01

    Perineuronal nets (PNNs) are lattice-like supramolecular assemblies of extracellular glycoproteins that surround subsets of neuronal cell bodies in the mammalian telencephalon. PNNs emerge at the end of the critical period of brain development, limit neuronal plasticity in the adult brain, and are lost in a variety of complex brain disorders diseases, including schizophrenia. The link between PNNs and schizophrenia led us to question whether neuronally expressed extracellular matrix (ECM) molecules associated with schizophrenia contribute to the assembly of these specialized supramolecular ECM assemblies. We focused on collagen XIX—a minor, nonfibrillar collagen expressed by subsets of telencephalic interneurons. Genetic alterations in the region encoding collagen XIX have been associated with familial schizophrenia, and loss of this collagen in mice results in altered inhibitory synapses, seizures, and the acquisition of schizophrenia-related behaviors. Here, we demonstrate that loss of collagen XIX also results in a reduction of telencephalic PNNs. Loss of PNNs was accompanied with reduced levels of aggrecan (Acan), a major component of PNNs. Despite reduced levels of PNN constituents in collagen XIX-deficient mice (col19a1−/−), we failed to detect reduced expression of genes encoding these ECM molecules. Instead, we discovered a widespread upregulation of extracellular proteases capable of cleaving Acan and other PNN constituents in col19a1−/− brains. Taken together, these results suggest a mechanism by which the loss of collagen XIX speeds PNN degradation and they identify a novel mechanism by which the loss of collagen XIX may contribute to complex brain disorders.

  3. Anaglyph: Basalt Cliffs, Patagonia, Argentina

    NASA Technical Reports Server (NTRS)

    2000-01-01

    Basalt cliffs along the northwest edge of the Meseta de Somuncura plateau near Sierra Colorada, Argentina show an unusual and striking pattern of erosion. Stereoscopic observation helps to clarify the landform changing processes active here. Many of the cliffs appear to be rock staircases that have the same color as the plateau's basaltic cap rock. Are these the edges of lower layers in the basalt or are they a train of slivers that are breaking off from, then sliding downslope and away from, the cap rock. They appear to be the latter. Close inspection shows that each stair step is too laterally irregular to be a continuous sheet of bedrock like the cap rock. Also, the steps are not flat but instead are little ridges, as one might expect from broken, tilted, and sliding slices of the cap rock. Stream erosion has cut some gullies into the cliffs and vegetation (appears bright in this infrared image) shows that water springs from and flows down some channels, but land sliding is clearly a major agent of erosion here.

    This anaglyph was generated by first draping a Landsat Thematic Mapper image over a topographic map from the Shuttle Radar Topography Mission, then producing the two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and the right eye with a blue filter.

    Landsat satellites have provided visible light and infrared images of the Earth continuously since 1972. SRTM topographic data match the 30-meter (99-foot) spatial resolution of most Landsat images and provide a valuable complement for studying the historic and growing Landsat data archive. The Landsat 7 Thematic Mapper image used here was provided to the SRTM project by the United States Geological Survey, Earth Resources Observation Systems (EROS) Data Center,Sioux Falls, South Dakota.

    Moybdenum-based subnanometre diameter nanowires are easy to synthesize and disperse, and they exhibit a variety of functional properties in which they are superior to other one-dimensional materials. However, further progress in the understanding of physical properties and the development of new and specific applications have so far been impeded by the fact that their structure was not accurately known. Here we report on a combination of systematic x-ray diffraction and extended x-ray absorption fine structure experiments, and first-principles theoretical structure calculations, which are used to determine the atomic skeletal structure of individual Mo6S9-xIx (MoSIx) nanowires, their packing arrangement within bundles and their electronic band structure. From this work we conclude that the variations in functional properties appear to arise from different stoichiometry, not skeletal structure.

    The pigment vermilion (HgS) was used to color the fore edge, tail and head of books. Dissemination and quantification of Hg present in the ink used to color books from XVIII and XIX centuries are reported. Mercury is a very toxic element for the human body, therefore it is extremely important to know whether Hg tends to disseminate throughout the paper or stays confined to the borders of the books with less danger for readers. Synchrotron X-ray microprobe was used to evaluate Hg dissemination from the border to the centre of the paper sheet. The diffusion pattern of Hg was compared with the results obtained by a portable X-ray fluorescence spectrometer and mean quantitative calculations were obtained by a stationary X-ray fluorescence system with triaxial geometry. The results showed high concentrations of Hg in the external regions, but no diffusion was observed for the inner parts of the paper.

    Multiple observations of Capella obtained between 28 August 1999 and 29 April 2002 provide high signal-to-noise spectra useful for assessing the atomic data used in plasma spectral emission codes. We discuss the X-ray Fe XVIII and XIX line emission seen with the Chandra HETG compared to far ultraviolet lines from FUSE and the extreme ultraviolet emission lines from EUVE and Chandra LETG. We find more than a factor of 2 discrepancy between the X-ray lines from 3d-2p and 3s-2p transitions, compared with predictions from the Astrophysical Plasma Emission Code (APEC). This discrepancy is larger than the similar pattern of discrepancy found in Fe XVII. The forbidden lines from FUSE and the strong EUV resonance lines shed additional light on the problem.

    In Argentina, vaccines for immuno-preventable diseases are regulated by the national regulatory agency, the Administración Nacional de Medicamentos, Alimentos y Tecnología Médica (the National Administration of Drugs, Food and Medical Devices, or ANMAT) created in 1992 to ensure efficacy and safety of drugs, food and medical devices available in the country, according to Law 16,463 and Decree 150/92. ANMAT has licensed 84 out of 157 vaccines registered in Argentina. Since 1994, ANMAT evaluated, approved and inspected 20 clinical trials with vaccines (1.8% of the 1062 trials approved by the agency since that time). The National System of Pharmaco-vigilance has received 318 communications of eventual adverse post-vaccination events (0.3% of the total). In addition, ANMAT provides support to the National Immunisation Programme. The current procedure is to follow international guidelines in the field, to be prepared for new, rapidly changing scenarios.

    We describe the first molecular confirmation of Rickettsia rickettsii, the cause of Rocky Mountain spotted fever (RMSF), from a tick vector, Amblyomma cajennense, and from a cluster of fatal spotted fever cases in Argentina. Questing A. cajennense ticks were collected at or near sites of presumed or confirmed cases of spotted fever rickettsiosis in Jujuy Province and evaluated by polymerase chain reaction assays for spotted fever group rickettsiae. DNA of R. rickettsii was amplified from a pool of A. cajennense ticks and from tissues of one of four patients who died during 2003-2004 after illnesses characterized by high fever, severe headache, myalgias, and petechial rash. The diagnosis of spotted fever rickettsiosis was confirmed in the other patients by indirect immunofluorescence antibody and immunohistochemical staining techniques. These findings show the existence of RMSF in Argentina and emphasize the need for clinicians throughout the Americas to consider RMSF in patients with febrile rash illnesses.

The gradual installation of the device of maternities in the Argentina, and especially in the city of Buenos Aires, was not exempt from difficulties, in the medical boarding of the pregnant woman and parturient as well as in the cultural conception of the mothers. This fact presupposes an increase of the phenomenon called "puerperal madness" in the moment where the displacement of the act of giving birth in the house to the hospital takes place. Certainly, the clinical fact of the "puerperal madness" exceeds to the historical social context, and in this way appear all the psychopathologies related to the pregnancy, childbirth and the puerperal fevers. We also must take in account the influence of the medical speech about the feminine body and his translation to a scientific and institutional speech never before experienced in Argentina.

    Argentina occupies the southern portion of the Brazilian craton in an extensively accreted zone. The plate tectonics setting of Argentina involves a Gondwana reentrant (South America, Africa, and Antarctica) whose evolution as yet is uncertain. Along the east flank of the Andes, late Paleozoic and early Mesozoic taphrogenic (rift) basins of apparent wrench-rift origin contain 85% of the discovered oil and gas in Argentina. Movement and docking of the Patagonian and Deseado-Falkland massifs (microplates.) were accompanied by intense late Paleozoic-early Mesozoic volcanic activity and the development of intracraton and interplate rifts where restricted lacustrine or shallow marine source rocks were deposited. Subsequent late Tertiary foredeep folding on the semi-cratonic accreted zone developed on the western margin of the rift basins, but did not affect the undisturbed portion of the basins. Source rocks include marine bituminous shales of Devonian, Jurassic, and Cretaceous ages, and lacustrine bituminous shales of Triassic and Jurassic ages. Reservoir rocks are predominately clastics, generally interbedded with the source sequence. The undiscovered oil and gas resources are assessed at 60 to 70% of the amount already discovered, divided equally between producing and nonproducing basins.

    Porphyrias are a group of metabolic diseases that arise from deficiencies in the heme biosynthetic pathway. A partial deficiency in hydroxymethylbilane synthase (HMBS) produces a hepatic disorder named Acute Intermittent Porphyria (AIP); the acute porphyria is more frequent in Argentina. In this paper we review the results obtained for 101 Argentinean AIP families and 6 AIP families from foreign neighbour countries studied at molecular level at Centro de Investigaciones sobre Porfirinas y Porfirias (CIPYP). Thirty-five different mutations were found, of which 14 were described for the first time in our population. The most prevalent type of mutations was the missense mutations (43%) followed by splice defects (26%) and small deletions (20%). An odd case of a double heterozygous presentation of AIP in a foreign family from Paraguay is discussed. Moreover, it can be noted that 38 new families were found carrying the most frequent mutation in Argentina (p.G111R), increasing to 55.66% the prevalence of this genetic change in our population and adding further support to our previous hypothesis of a founder effect for this mutation in Argentina. Identification of patients with an overt AIP is important because treatment depends on an accurate diagnosis, but more critical is the identification of asymptomatic relatives to avoid acute attacks which may progress to death.

    Geographical clusters are defined as the occurrence of an unusual number of cases higher than expected in a given geographical area in a certain period of time. The aim of this study was to identify potential geographical clusters of specific selected congenital anomalies (CA) in Argentina. The cases were ascertained from 703,325 births, examined in 133 maternity hospitals in the 24 provinces of Argentina. We used the spatial scan statistic to determine areas of Argentina which had statistically significant elevations of prevalence. Prenatal diagnosis followed by referral of high-risk pregnancies to high complexity hospitals in a hospital-based surveillance system can create artifactual clusters. We assessed the referral bias by evaluating the prevalence heterogeneity within each cluster. Eight clusters of selected CAs with unusually high birth prevalence were identified: anencephaly, encephalocele, spina bifida, diaphragmatic hernia, talipes equinovarus, omphalocele, Cleft lip with or without cleft palate (CL/P), and Down syndrome. The clusters of Down syndrome and CL/P observed in this study match the previously reported clusters. These findings support local targeted interventions to lower the prevalence of the CAs and/or further research on the cause of each cluster. The clusters of spina bifida, anencephaly, encephalocele, omphalocele, congenital diaphragmatic hernia, and talipes equinovarus may be influenced by prenatal diagnosis and referral to high complexity hospitals.

    Local transmission of dengue fever virus in Argentina is increased by the presence of Aedes aegypti mosquitoes and dengue outbreaks in neighboring countries. From 1995 to 2001, a laboratory-based active surveillance program detected 922 dengue cases. Indigenous transmission involving dengue-1 and -2 serotypes was confirmed only in subtropical areas in northern Argentina.

  16. An Assessment of the Fe XVIII and Fe XIX Line Ratios from the Chandra Grating Observations of Capella

    Observations of Fe XVIII and Fe XIX X-ray, extreme-UV, and far-UV line emission, formed at the peak of Capella's (α Aurigae's) emission measure distribution and ubiquitous in spectra of many cool stars and galaxies, provide a unique opportunity to test the robustness of Fe XVIII and Fe XIX spectral models. The Astrophysical Plasma Emission Code (APEC) is used to identify over 35 lines from these two ions alone, and to compare model predictions with spectra obtained with the Chandra Low Energy Transmission Grating and High Energy Transmission Grating Spectrometers, the Far Ultraviolet Spectroscopic Explorer (FUSE), and the Extreme Ultraviolet Explorer. Some flux discrepancies larger than a factor of 2 are found between observations of Fe XVIII and Fe XIX lines and predictions by APEC and other models in common use. In particular, the X-ray resonance lines for both ions are stronger than predicted by all models relative to the EUV resonance lines. The multiwavelength observations demonstrate the importance of including dielectronic recombination and proton-impact excitation, and of using accurate wavelengths in spectral codes. These ions provide important diagnostic tools for 107 K plasmas currently observed with Chandra, XMM-Newton, and FUSE.

  17. Tobacco industry targeting youth in Argentina

    2013-01-01

    Background/aim Argentina has one of the highest cigarette smoking rates among both men and women in the Americas and no legislated restrictions on tobacco industry advertising. The tobacco industry has traditionally expanded markets by targeting adolescents and young adults. The objective of this study was to determine whether and how the tobacco industry promotes cigarettes to adolescents in Argentina. Methods We conducted a systematic search of tobacco industry documents available through the internet dated between 1995 and 2004 using standard search terms to identify marketing strategies in Argentina. A selected review of the four leading newspapers and nine magazines with reported high readership among adolescents was completed. The selected print media were searched for tobacco images and these were classified as advertisements if associated with a commercial product or as a story if not. Results The tobacco industry used market segmentation as a strategy to target Argentinean consumers. British American Tobacco (BAT) undertook a young adult psychographic study and classified them as “progressives”, “Jurassics” or “conservatives” and “crudos” or “spoiled brats”. BAT marketed Lucky Strike to the “progressives” using Hollywood movies as a vehicle. The tobacco industry also targeted their national brands to the conservatives and linked these brands with “nationalistic values” in advertising campaigns. Philip Morris promoted Marlboro by sponsoring activities directed at young people and they launched the 10 cigarettes packet as a starter vehicle. Conclusions The tobacco industry used psychographic segmentation of the population and developed advertising strategies focused on youth. Tobacco control researchers and advocates must be able to address these strategies in counter-marketing interventions. PMID:18299308

    Monitoring of resistance of Aedes aegypti to temephos was implemented in the provinces of Formosa and Misiones, Argentina, as a response to the need to improve the vigilance for the dengue vector in areas of high risk of dengue. Eggs collected in each locality were reared, and susceptibility to temephos was assayed using larval bioassays. A weak decrease in susceptibility of larvae to temephos was observed in Clorinda and Puerto Iguazú, indicating an incipient resistance with a resistance ratio of 3. No control failures have been observed yet, and this program should allow the early detection of a real problem in our country.

    2015-01-01

    The article considers activity of municipal self-governments of Russia concerning support of sanitary epidemiological well-being of cities in the late XIX--early XX centuries. The acuteness of problem of sanitary conditions of urban settlements particularly became visible in post-reform period due to increasing of number of urban population, alteration of setup and rhythm of life in cities, appearance of new forms of worker's daily chores. Al this, against the background of underdevelopment of communal sphere aggravated epidemiological situation in cities. The impulse to improvement and development of sanitary control was made by the city regulations of 1870 presenting to town authorities the right to deal with sanitary issues. The significant input into improvement of cities was made first of all at the expense of construction of water supplies and sewerage and support of sanitary control of these spheres of municipal economy. Under town councils of many cities the sanitary commissions were organized to support permanent sanitary control in town. The development of town sanitation followed the way of specialization. The housing and communal, trade and food, school and sanitary and sanitary and veterinary control were organized.

    We compute the wavelengths and oscillator strengths for the 3s, 3d → 2p, and 3p → 2s emission lines in Fe XIX and Fe XX ions by using a configuration interaction Dirac-Fock and Dirac-Fock-Sturm method combined with second-order Brillouin-Wigner perturbation theory. We provide a complete list of computed wavelengths and oscillator strengths in both the velocity and length gauge for these transitions, many of which have never previously been reported. A comparison of our data with laboratory measurements and other theoretical predictions allows us to estimate an uncertainty of ~2 mÅ in the wavelengths and an uncertainty of 2%-3% in the oscillator strengths. We expect that our calculations will provide a means of identifying emission lines from astrophysical sources and improve the ability to detect blending in X-ray grating spectra from Chandra and XMM-Newton. As an example, we present a simulated emission spectrum of Capella and find improved agreement between the observations and our calculations, compared with previous data sets.

    A Landsat MSS and TM classification approach based on three features derived from the greenness profile has proved very effective in separating and identifying corn, soybeans, and other ground cover classes in the U.S. The objective of this study is to investigate the separation of summer crops in Argentina, one of the most important commodity exporters, using the same greenness profile features that have proved effective in the U.S. Corn Belt. The area chosen for study is a more complex cropping practice area located in the north-west corner of Buenos Aires province in Pampa Humeda, where corn, soybean, sorghum, sunflower, and pastures are cultivated. It is shown that the profile features can provide very effective separation, except in the case of corn from sorghum. Separation between corn and soybeans was found to be greater than in the U.S. This study suggests that the automatic, unsupervised classification approach developed in the U.S., with relatively minor modification, can be used for summer crop area estimation in Argentina.

    Dengue outbreaks have occurred yearly in Argentina since 1998. A number of candidate vaccines have been tested in endemic countries. The most advanced one was licensed in three countries of Latin America for children over 9 years of age. In the present article the benefits and drawbacks of these vaccines as well as the challenges for the implementation of a vaccination strategy in Argentina are discussed. Furthermore, a risk stratification strategy with new criteria and a multidisciplinary vision is suggested as a possible path for the assessment of the pertinence of a vaccination program in areas showing the highest risk of dengue transmission and/or for people at the greatest risk of developing severe dengue. It is also suggested that the definition regarding the status of endemicity should take into account the local realities. Finally, this paper proposes a broad discussion on the evidences, the expected impact and instrumental aspects that would be involved in the incorporation of a dengue vaccine, marketed or in development, into the national immunization program, and especially which subpopulation should be targeted for the immunization strategy to be cost-effective.

    The Paced Auditory Serial Addition Test (PASAT) is one of the most used neuropsychological tests to assess information processing speed and working memory in brain injured patients. This study was carried out with the purpose of obtaining normative data for the PASAT-3″ in a healthy Argentinean population, which would result in a reference control population. The PASAT-3″ was administered in a sample of 296 healthy voluntary subjects, born and living in Argentina. The age range went from 20 to 70 years-old. The level of education was 0 to 13 or more years of schooling. The sample obtained a mean of 44.60 (SD = 10.72) in the PASAT-3″. It was found that the score obtained in the PASAT-3″ was related to the age and the level of instruction of the participants. Their performance diminished as age increased and, conversely, it increased as the level of instruction was higher. Normative data was obtained for a Latin American population from Argentina. Percentile distributions obtained by decades of age and different levels of education should be considered as useful reference values for clinicians and investigators when applying the PASAT-3″ to assess cognitive function in different pathologies.

    SLR technique is a proved astro-geodetic art with a significant power to contribute to Earth and Space Sciences. Therefore, scientific applications of SLR System are able to perform multiple tasks in the fields of Astrometry, Geodesy and Geophysics. The results we show here were obtained from satellite observations made at SLR 7406 Station of Observatorio Astronómico Félix Aguilar (OAFA) in San Juan, Argentina. The telescope was installed early on 2006, in concordance with an International Cooperation Agreement between Universidad Nacional de San Juan, Argentina and Chinese Academy of Sciences. In this abstract we show the current research being done with ILRS 7406 station: Length of day (LOD) and Angular velocity of Earth Rotation, calculated weekly; Pole Motion. ILRS7406 is daily surveying Pole coordinates x and y; Tracking SLR to GNSS constellations. SLR System contributes to the adjustment and validation of satellite GALILEO, GPS, GLONASS, and BEIDOU orbits. Our station is nowadays member of the new ITRF 2014 frame, and these past years has been one of the 3 highest producing SLR Stations on the ILRS net, composed of about 40 stations distributed all around the world. The obtained results during this first 10 years of experience are useful to enhance the traditional collaboration between OAFA and international services such as ILRS, IERS and NASA.

    Letter and category fluency tasks are used to assess semantic knowledge, retrieval ability, and executive functioning. The original normative data have been obtained mainly from English speaking populations; there are few papers on norms in other languages. The purpose of this study was to collect normative scores in Argentina and to evaluate the effects of sex, age, education and cognitive status on the letter and category fluency tasks, in 266 healthy Spanish-speaking participants (16 to 86 years). Mean education span was 12.8 +/- 4 years. In each subject a neuropsychological battery (Minimental State Exam, Signoret Memory Battery, Boston Naming Test and Trail Making Test) was carried out as well as category fluency (naming animals in one minute) and letter fluency (words beginning with letter "p" in one minute). The sample was arranged into a group of subjects with less than 45 years and further groups up to 10 more years, until 75 years (or more) with three different levels of education. Significant effects were found for age, education, and Minimental State Exam on performance of both fluencies. Mean performance scores are presented for each group to be used in Argentina.

    2015-04-16

    Fusarium temperatum and Fusarium subglutinans isolated from the Northwest region (NOA region) of Argentina were characterized using a polyphasic approach based on morphological, biological and molecular markers. Some interfertility between the species was observed. The phylogenetic analysis showed that the two species represented two clades strongly supported by bootstrap values. The toxigenic profile of the strains was also determined. F. temperatum strains were fusaproliferin and beauvericin producers, and only some strains were fumonisin B1 producers. All F. subglutinans strains produced fusaproliferin but none produced beauvericin, indicating a potential toxicological risk from maize harvested in the NOA region of Argentina. This study provides new information about F. temperatum isolated from maize in Argentina.

    The taxonomy of some ophiuroids reported from off Argentina, western Antarctica and the SW Atlantic Ocean is reviewed. The species Amphilepis sanmatiensis, known only from the small holotype, is a synonym of Amphioplus lucyae. This synonymy removes the only reported endemic ophiuroid from Argentina. The species name "Ophiacantha ingrata Koehler, 1923" used for specimens from South Georgia is invalid; the specimens are likely to belong to one of two cryptic species within the O. vivipara complex. Specimens of Amphiura joubini reported from Argentina are re-identified as Amphiura princeps, and specimens of Ophiactis amator from the Antarctic Peninsula are re-identified as Ophiactis asperula.

    In Argentina, the national guidelines for lipid control emphasize the use of relatively inexpensive low- or moderate-potency statins by patients at high risk (>20 %) of a cardiovascular event. The objective of this study was to compare the impact and costs of the current national CVD prevention guidelines with regard to morbidity and mortality in Argentina with the impact and costs of three strategies that incorporate high-potency statins. We used the CVD Policy Model-Argentina to model the proposed interventions. This model is a national-scale, state-transition (Markov) computer simulation model of the CVD incidence, prevalence, mortality, and costs in adults 35-84 years of age. We modeled three scenarios: scenario 1 lowers the risk threshold for treatment to >10 % according the Framingham Risk Score (FRS); scenario 2 intensifies statin potency under current treatment thresholds; and scenario 3 combines both scenarios by lowering the treatment threshold to ≥10 % FRS and intensifying statin potency. Scenario 1 would translate into 1400 fewer MIs and 500 fewer CHD deaths every year, a 3 % and 2 % reduction, respectively. Scenario 2 would lead to 2000 fewer MIs and 1000 fewer CHD deaths every year. Scenario 3 would result in the greatest reduction in MIs and CHD deaths, with 3400 fewer MIs and 1400 fewer CHD deaths every year, which translates to a 7 % and 6 % reduction, respectively. All scenarios were cost-effective if the cost of a high-potency statin pill was under US$0.25. Incorporating those individuals with greater than 10 % cardiovascular risk and the use of high-potency statins into Argentina's national lipid guidelines could result in fewer CHD deaths and events at a reasonable cost.

    As emergency medicine (EM) has developed as a medical specialty throughout the world, each country has followed its own path to official recognition. Despite a successful EM model in the United States, some countries, especially those that require government approval of new medical specialties, have often found it difficult to attain recognition. As of early 2009, Argentina had yet to recognize EM as an official specialty, although some regional governments have acknowledged the specialty's status. The Argentine Society of EM has taken a number of steps and proposed educational paths to EM specialization to convince Argentina's political decision-makers that Emergency Medicine is a fundamental step toward a modern medical system. Such national recognition would further an already thriving EM community and improve the quality of patient care in Argentina. To assist colleagues around the world who are pursuing or will pursue this goal, this article outlines Argentina's complex and ongoing path to specialty recognition. Copyright 2010 Elsevier Inc.

    One of the main conditions for the sustainable development of any country is the food security of the population, based on the development of agriculture. This condition can be realized through the efficient use of the productive capacity of agriculture, and above all natural resources. From 1882 to 1887 in the Nizhegorodskaya gubernia (province) complex physiographic (landscape) researches were conducted by V.V. Dokuchaev and his followers. This investigation was focused on studying the relationship between the soils and the environment, having no parallel either in Russia or abroad, and received evaluation of the soils was the first experience of such a scale and nature. Reports of the expedition were presented in 14 volumes on the natural science of the study, and 11 volumes of economic statistics. Natural science volume includes descriptions of irrigation and hydrography, geology, soil and vegetation in uezds (districts). Economic volume represent a set of common data on the situation of the peasant economy, they contain information about the number of arable land, including fertilized, hayfields, forests, manure stocks, livestock, harvest volumes, proportions of cultivated crops. The aim of this research was to study the list and structure of crops cultivated in the Nizhegorodskaya gubernia in the XIX century and their compliance with the soil and climatic conditions. From the materials of the expedition reports for the eight districts of the Nizhegorodskaya gubernia was compiled a list of crops and crop area information which was introduced in the GIS (MapInfo). Geographic information systems were used to visualize the collected material in the form of maps, cartograms and charts. For the conformity assessment of soil and climatic conditions of the studied area of selected crops a map "Agricultural zoning of Russia for optimal crop growing" by I.I. Karmanov and D.S. Bulgakov (National Soil Atlas, 2011) was applied. According to this map the Nizhegorodskaya

    A so-called XUV excess has been suspected with the relative fluxes of Fe XVIII and Fe XIX lines in XUV and EUV spectra of the star Capella as observed by the Chandra spacecraft [1] when comparing the observations with simulations of stellar spectra based on APEC or FAC. We have addressed this problem by laboratory studies using the Livermore electron beam ion trap (EBIT). Our understanding of the EBIT spectrum is founded on work by Brown et al. [2]. The electron density of the electron beam in an EBIT is compatible to the density in energetic stellar flares. In our experiments, the relative detection efficiencies of two flat-field grating spectrographs operating in the EUV (near 100 Å) and XUV (near 16 Å) ranges have been determined using the calculated branching ratio of 1-3 and 2-3 transition in the H-like spectrum O VIII. FAC calculations assuming several electron beam energies and electron densities serve to correct the EBIT observations for the Maxwellian excitation in a natural plasma. In the EUV, the line intensity pattern predicted by FAC agrees reasonably well with the laboratory and Capella observations. In the XUV wavelength range, agreement of laboratory and astrophysical line intensities is patchy. The spectral simulation results from FAC are much closer to stellar and laboratory observation than those obtained by APEC. Instead of claiming an XUV excess, the XUV/EUV line intensities can be explained by a somewhat higher temperature of Capella than the previously assumed T=6 MK.

    This paper reports that Brazil and Argentina have agreed to joint exploration and development of oil and gas in Argentina's Northeast basin. Although not covered by the accord, the venture could lead to a 2,400 km, $2.5 billion gas pipeline system form the Argentine basin to southern Brazil, beyond almost $2 billion in exploration and development costs. The Northeast basin has proved reserves of 95 million bbl of crude oil and 2.1 tcf of gas.

    Tobacco use is the leading preventable cause of deaths worldwide. The MPOWER package, the six recommended policies of the World Health Organization (WHO) to reverse the tobacco epidemic, strongly recommends monitoring tobacco use trends. Because evidence indicates that smoking addiction often starts before the age of 18 years, there is a need to monitor tobacco use among youths. During 2011, a National Tobacco Control Law was enacted in Argentina that included implementation of 100% smoke-free environments, a comprehensive advertising ban (prohibiting advertising, promotion, and sponsorship of cigarettes or tobacco products through any media or communications outlets), pictorial health warnings, and a prohibition against the sale of tobacco products through any means to persons aged <18 years. To ascertain trends in tobacco use among youths in Argentina, the Argentina Ministry of Health and CDC analyzed data from the Global Youth Tobacco Survey (GYTS) for 2007 and 2012 (the next year that it was administered in Argentina). The findings indicated that the overall proportion of youths aged approximately 13-15 years who reported ever smoking a cigarette declined from 52.0% in 2007 to 41.9% in 2012 with significant decreases among both males and females. In 2012, 52.5% of youths in Argentina reported secondhand smoke (SHS) exposure in their homes and 47.5% in enclosed public places in the 7 days preceding the survey. Increased public education and tobacco control efforts will be important to discouraging tobacco use and decreasing SHS exposure among youths in Argentina.

    Common vampire bat populations distributed from Mexico to Argentina are important rabies reservoir hosts in Latin America. The aim of this work was to analyse the population structure of the rabies virus (RABV) variants associated with vampire bats in the Americas and to study their phylodynamic pattern within Argentina. The phylogenetic analysis based on all available vampire bat-related N gene sequences showed both a geographical and a temporal structure. The two largest groups of RABV variants from Argentina were isolated from northwestern Argentina and from the central western zone of northeastern Argentina, corresponding to livestock areas with different climatic, topographic and biogeographical conditions, which determined their dissemination and evolutionary patterns. In addition, multiple introductions of the infection into Argentina, possibly from Brazil, were detected. The phylodynamic analysis suggests that RABV transmission dynamics is characterized by initial epizootic waves followed by local enzootic cycles with variable persistence. Anthropogenic interventions in the ecosystem should be assessed taking into account not only the environmental impact but also the potential risk of disease spreading through dissemination of current RABV lineages or the emergence of novel ones associated with vampire bats. © 2014 John Wiley & Sons Ltd.

    Objective: To measure the economic burden of diabetes in Argentina by age, gender and region for the year 2005, in disability-adjusted life years (DALYs). Methods: DALYs were estimated by the sum of years of life lost due to premature death (YLL) and years of life lived with disability (YLD). Results: In the population studied (20 to 85 years), the burden of diabetes without complications was 1.3 million DALYs, 85% of which were caused by disabilities. Whereas mortality rates (YLL) increased as a function of age, YLD showed the opposite relationship. Women had higher burden of disease values, represented by 51 and 61% of YLL and YLD, respectively, independently of age. Conclusions: Our results demonstrate that disabilities are a key component of diabetes burden; its regular and systematic estimation would allow to design effective prevention strategies, to assess the impact of their implementation and to optimize resource allocation based on objective evidence.

    In this paper, we identify 37 companies that produce nano-enabled products in Argentina. We locate the products of these firms in terms of both their economic sector and position in a value chain. The research was done through a four-step methodology. Firstly, an inventory of firms was created. Secondly, the firms were classified by their economic sector, following the United Nations economic classification. Thirdly, the firms were located within a simple nanotechnology value chain. Finally, the products were classified according to their final destination, being either means of production or final consumer products. The results show that healthcare, cosmetics, and medicine is the most represented sector along the value chain, followed by electronics.

    In the Buenos Aires province of Argentina, Gas de Estado is constructing the future heart of the petrochemical complex, Bahia Blanca. The complex contains 2 absorption-refrigeration plants, a gas compressing plant, equipment maintenance shops and an important operations base for the Argentine truck gas pipelines. This will be the largest LPG plant in Latin America. The General Cerri plant, under construction, is located in an area of 40,000 sq m with new installations to extract ethane and higher hydrocarbons. The design optimizes the extraction of hydrocarbons from the natural gas and recovers 76% of the ethane. Selection of the process resulted from an investigation that compared the system with processes that use water cooling and absorption with refrigerated oil.

  9. Pie de Palo, Argentina: A cataclastic diapir

    NASA Astrophysics Data System (ADS)

    2009-03-01

    The term cataclastic diapirism is proposed for the low-temperature extrusion of highly fractured rocks through more competent strata to produce domed topographies at the surface. The process is illustrated by reference to the geomorphology, neotectonics and microseismicity of the Pie de Palo, an elongated ridge in the western Sierras Pampeanas of Argentina composed of shattered and sheared Lower Palaeozoic rocks and subject to coseismic uplift. The Pie de Palo is conventionally interpreted as a fault-driven basement fold linked to low-angle eastward subduction of the Nazca plate beneath South America; the diapiric model implies instead that deformation is powered by regional compression from west-verging, near-surface, crustal shortening which results ultimately from Atlantic spreading.

  10. Republic of Argentina: Argentina is the envy of other Latin American countries.

    1984-05-01

    Argentina's economic and political history may appear grim by US standards, but it is envied by many other Latin American nations, and by Latin American standards its demographic situation is enviable as well. A low population growth rate combined with abundant natural resources means that the poverty of its neighbors has not hit Argentina. Almost everyone eats well and the staple is beef -- about 240 pounds per capita per year. Final figures for the 1980 census of population and housing report a total of 27.9 million people, an increase of 17% from the 23.8 million people counted in 1970. The average annual rate of increase was 1.5% a year. With the exception of Uruguay, this is the lowest rate of increase in continental Latin America. The birthrate of 24 births/1000 population is third only to Chile and Uruguay as the lowest in continental Latin America, although the death rate is about average at 9/1000. After several decades of decline, the death rate is rising again because the population is aging. A current problem is the emigration of Argentinians to other countries, a problem that is most severe among highly trained professionals. Over 1/3 of those who leave Argentina come to the US, with Spain and Canada receiving the next highest numbers. At its current growth rate, Argentina's population will double in 46 years. It is estimated that the population was 29.1 million in 1983; it is projected to be 34.5 million by the year 2000 and 39.6 million by 2020. Over 1/3 of the population live in and around Gran Buenos Aires, the largest metropolitan area in South America and among the ten largest in the world. There is a large core of Spanish descendents still living, but some other European countries are well represented also. The 1980 census recorded 7.1 million households; the average number of persons per household was 3.9. There were 8.2 million dwellings counted in 1980, with an average of 3.3 people per dwelling. 13% of all dwellings were unoccupied at the

    Andes virus was identified in 1995 as the etiologic agent of Hantavirus Pulmonary Syndrome (HPS) in Southern Argentina. We describe herein the main clinical characteristics of 25 HPS confirmed cases acquired in this area between 1993 and September 1999. The mean age was 34 years (range 11-70), with 72% males. Clinical characteristics were similar to those previously reported for Sin Nombre virus (SNV) cases. However, in this group of patients we also observed conjuntival injection in 10/25 (42%), facial flushing in 8/25 (33%), pharyngeal congestion in 7/25 (29%) and petechiae in 3/25 (12%). On the other hand, BUN was increased in 83% of cases (mean 0.77 g/l range 0.31-2.01). Mean serum creatinine concentration was 26.8 mg/l (range: 8.1-110 mg/l) with serum creatinine being higher than 20 mg/l in 8/15 patients (53%). Urinalysis was abnormal in 12/12 cases and was characterized by presence of proteins, red blood cells and granular casts. Aminotransferases were increased in 90% of cases with levels 5-10 times over normal values in 50% of cases. Serum creatine kinase concentration was elevated in 11/14 cases. Two patients required hemodialysis. Case fatality rate was 44% (11/25) and 10 of these cases died among the first 10 days of illness. Mononuclear myocarditis was observed in two cases, a finding that has not been reported for SNV cases. During the 1996 HPS outbreak in Southern Argentina due to Andes virus, there were epidemiological and molecular evidences of person-to-person transmission, a feature not previously shown for other members of the hantavirus genus. These data would also be indicative of some distinctive clinical characteristics of HPS caused by Andes virus, with more frequent renal involvement than in SNV cases.

    En Julio de 1997 se terminó con la primera parte de la instalación del ``Coronógrafo de Espejo para la Argentina'' en la estación de altura Carlos U. Cesco (El Leoncito), gracias al esfuerzo de la gente del Max Planck Institut für Aeronomie (Alemania), del OAFA y del IAFE. Dicho coronógrafo forma parte de un programa de ciencia bilateral entre Alemania y Argentina. El propósito del mismo, en conjunción con otros telescopios solares y terrestres, es contribuir a un mejor entendimiento de cuestiones fundamentales de la física solar. Para ello, ya está observando la corona de emisión en el verde (Fe XIV), rojo (Fe X) y Hα entre 1.05 y 2 radios solares aproximadamente. El diseño del instrumento, el cual fuera ya presentado en esta misma reunión en La Plata en 1996, es esencialmente similar al del telescopio LASCO-C1 a bordo del Solar Heliospheric Observatory (SOHO). La adquisición de datos se realiza con un CCD de 1280x1024 pixels, codificando en 12 bits, pudiendo ser el mismo operado en forma remota. En esta reunión presentaremos algunas de las observaciones realizadas durante la puesta a punto del instrumento en el período julio-setiembre de 1997. Asimismo expondremos cómo y por qué sus resultados complementarán a los de su par en el espacio.

    This volume contains the lectures and short talks given at the XIX International School on Nuclear Physics, Neutron Physics and Applications. The School was held from 19-25 September 2011 in 'Club Hotel Bolero' located in the 'Golden Sands' (Zlatni Pyasaci) Resort Complex on the Black Sea coast, near Varna, Bulgaria. The School was organized by the Institute for Nuclear Research and Nuclear Energy of the Bulgarian Academy of Sciences. The co-organizer of the School was the Bulgarian Nuclear Regulatory Agency and the Bogoliubov Laboratory of Theoretical Physics of the Joint Institute for Nuclear Research - Dubna. According to long-standing tradition the School has been held every second year since 1973. The School's program has been restructured according to our enlarged new international links and today it is more similar to an international conference than to a classical nuclear physics school. This new image attracts many young scientists and students from around the world. This year - 2011, we had the pleasure of welcoming more than 50 distinguished scientists as lecturers. Additionally, 14 young colleagues received the opportunity to each present a short contribution. The program ranged from recent achievements in areas such as nuclear structure and reactions to the hot topics of the application of nuclear methods, reactor physics and nuclear safety. The 94 participants enjoyed the scientific presentations and discussions as well as the relaxing atmosphere at the beach and during the pleasant evenings. The main topics were as follows: Nuclear excitations at various energies Nuclei at high angular moments and temperature Structure and reactions far from stability Symmetries and collective phenomena Methods for lifetime measurements Astrophysical aspects of nuclear structure Neutron nuclear physics Nuclear data Advanced methods in nuclear waste treatment Nuclear methods for applications Several colleagues helped with the organization of the School.

    Cardiovascular disease (CVD) is the leading cause of death in adults in Argentina. Sodium reduction policies targeting processed foods were implemented in 2011 in Argentina, but the impact has not been evaluated. The aims of this study are to use Argentina-specific data on sodium excretion and project the impact of Argentina's sodium reduction policies under two scenarios - the 2-year intervention currently being undertaken or a more persistent 10 year sodium reduction strategy. We used Argentina-specific data on sodium excretion by sex and projected the impact of the current strategy on sodium consumption and blood pressure decrease. We assessed the projected impact of sodium reduction policies on CVD using the Cardiovascular Disease (CVD) Policy Model, adapted to Argentina, modeling two alternative policy scenarios over the next decade. Our study finds that the initiative to reduce sodium consumption currently in place in Argentina will have substantial impact on CVD over the next 10 years. Under the current proposed policy of 2-year sodium reduction, the mean sodium consumption is projected to decrease by 319-387 mg/day. This decrease is expected to translate into an absolute reduction of systolic blood pressure from 0.93 mmHg to 1.81 mmHg. This would avert about 19,000 all-cause mortality, 13,000 total myocardial infarctions, and 10,000 total strokes over the next decade. A more persistent sodium reduction strategy would yield even greater CVD benefits. The impact of the Argentinean initiative would be effective in substantially reducing mortality and morbidity from CVD. This paper provides evidence-based support to continue implementing strategies to reduce sodium consumption at a population level.

    A report and an updated list with comments on the species of freshwater molluscs of Argentina which covers an area of 2 777 815 km2 is presented. Distributions of Gastropoda and Bivalvia families, endemic, exotic, invasive as well as entities of sanitary importance are also studied and recommendations on their conservation are provided. Molluscs related to the Del Plata Basin have been thoroughly studied in comparison to others areas of the country. This fauna exhibits relatively the biggest specific richness and keeps its affinity with the fauna of other regions of the basin in areas of Paraguay and Brasil. The 4 500 records of molluscs considered in this paper arise from the study of the collections of Museo Argentino de Ciencias Naturales "Bernardino Rivadavia", Buenos Aires; Museo de La Plata, La Plata and Fundación "Miguel Lillo", Tucumán. These institutions keep very important collections of molluscs in southern South America. Field information has recently been obtained and localities cited by other authors are also included in the data base. Until today, 166 species have been described, 101 belonging to 10 families of Gastropoda and 65 to 7 of Bivalvia. Families with highest specific richness are Lithoglyphidae (22) and Sphaeriidae (25), respectively. The number of endemic species (those present only in Argentina) by family is: Gastropoda: Ampullariidae (1), Cochliopidae (10), Lithoglyphidae (11), Thiariidae (3), Chilinidae (11), Lymnaeidae (2) and Physidae (2?); Bivalvia: Hyriidae (1?); Etheriidae (1?) and Sphaeriidae (10). Families with a distribution that comprise almost the whole country are: the Sphaeriidae and the gastropods Cochliopidae, Chilinidae and Lymnaeidae. Families Erodonidae and Solecurtidae (Bivalvia) were registered in mixohaline environments from Buenos Aires province. Gastropod families Thiaridae and Glacidorbiidae show a very restricted distribution. The rest of the families are present mainly in the center and north of the country

    Little is understood about racial/ethnic disparities in infant health in South America. We quantified the extent to which the disparity in preterm birth (PTB; <37 gestational weeks) rate between infants of Native only ancestry and those of European only ancestry in Argentina and Ecuador are explained by household socio-economic, demographic, healthcare use, and geographic location indicators. The samples included 5199 infants born between 2000 and 2011 from Argentina and 1579 infants born between 2001 and 2011 from Ecuador. An Oaxaca-Blinder type decomposition model adapted to binary outcomes was estimated to explain the disparity in PTB risk across groups of variables and specific variables. Maternal use of prenatal care services significantly explained the PTB disparity, by nearly 57% and 30% in Argentina and Ecuador, respectively. Household socio-economic status explained an additional 26% of the PTB disparity in Argentina. Differences in maternal use of prenatal care may partly explain ethnic disparities in PTB in Argentina and Ecuador. Improving access to prenatal care may reduce ethnic disparities in PTB risk in these countries.

    To evaluate how transnational tobacco companies, working through their local affiliates, influenced tobacco control policymaking in Argentina between 1966 and 2005. Analysis of internal tobacco industry documents, local newspapers and magazines, internet resources, bills from the Argentinean National Congress Library, and interviews with key individuals in Argentina. Transnational tobacco companies (Philip Morris International, British American Tobacco, Lorillard, and RJ Reynolds International) have been actively influencing public health policymaking in Argentina since the early 1970s. As in other countries, in 1977 the tobacco industry created a weak voluntary self regulating code to avoid strong legislated restrictions on advertising. In addition to direct lobbying by the tobacco companies, these efforts involved use of third party allies, public relations campaigns, and scientific and medical consultants. During the 1980s and 1990s efforts to pass comprehensive tobacco control legislation intensified, but the organised tobacco industry prevented its enactment. There has been no national activity to decrease exposure to secondhand smoke. The tobacco industry, working through its local subsidiaries, has subverted meaningful tobacco control legislation in Argentina using the same strategies as in the USA and other countries. As a result, tobacco control in Argentina remains governed by a national law that is weak and restricted in its scope.

    Type XIX collagen is a minor collagen associated with basement membranes. It was isolated for the first time in a human cDNA library from rhabdomyosarcoma and belongs to the FACITs family (Fibril Associated Collagens with Interrupted Triple Helices). Previously, we demonstrated that the NC1 domain of collagen XIX (NC1(XIX)) exerts anti-tumor properties on melanoma cells by inhibiting their migration and invasion. In the present work, we identified for the first time the integrin αvβ3 as a receptor of NC1(XIX). Moreover, we demonstrated that NC1(XIX) inhibits the FAK/PI3K/Akt/mTOR pathway, by decreasing the phosphorylation and activity of the major proteins involved in this pathway. On the other hand, NC1(XIX) induced an increase of GSK3β activity by decreasing its degree of phosphorylation. Treatments targeting this central signaling pathway in the development of melanoma are promising and new molecules should be developed. NC1(XIX) seems to have the potential for the design of new anti-cancer drugs.

    As in the rest of the world, there is a significant gap between scientific knowledge regarding diabetes mellitus and the daily practice outcome, in Argentina. Inadequate diabetes control combined with associated cardiovascular risk factors are responsible for an elevated morbid-mortality incidence and the consequent raise in the socioeconomic burden. Some of the factors leading to this situation are the late diagnosis of the disease, the clinical "inertia" (reluctance to prescribe insulin) and the poor education given to the health care team as well as the persons with diabetes. The implementation of a national diabetologic education program targeting health care providers, the persons with diabetes and their families, could contribute to optimize the appropriate insulin prescription, and consequently improve their life quality, while reducing the disease socioeconomic burden. In order to optimize the education program's strategy outcome, insulinization cabinets should be incorporated, the participation of all health systems (public health, social security and private health insurance companies), the media, health sciences, schools and the pharmaceutical industry are needed.

    Cholelithiasis is an important cause of morbidity in the world and it varies significantly depending on the region of study. To assess the prevalence of cholelithiasis in Buenos Aires. This is a cross-sectional, descriptive, observational study performed in a public hospital with tertiary care in Gastrointestinal Surgery. From July 2010 to December 2011, 1,875 healthy volunteers who underwent liver, gallbladder and pancreas ultrasound imaging were included and a questionnaire containing the individual's medical history was administered. The presence of cholelithiasis and its eventual risk factors were studied. Of 1,875 individuals, 866 were males (46.2%) and 1,009 females (53.8%), older than 20 years old with an average age of 46.1 + 16.7 years. Cholelithiasis was found in 410 inidviduals (21.9%); 285 (15.2%) diagnosed at the time of the study and 125 (67%) who had already undergone a cholecystectomy due to gallstones. The prevalence of cholelithiasis in Buenos Aires, capital city of Argentina, is 21.9%. A significant association was found between cholelithiasis and female gender, age, body mass index, history of colic pain, family history of cholelithiasis, smoking, fatty liver and number of pregnancies.

    Describing the development of PHC policy as promoted by Rosario Municipality (Argentina). A case-study was carried out during 2007 and 2008. Data was collected from secondary and primary sources (interviews, organisational census and observations). PHC development stages were identified by recognising the social norms which produced institutional change and transformation in municipal health services structure and health care and management models. The prevailing modes of governance in each stage were reconognised and characterised (clan, hierarchy and/or incentives). Four stages were identified between 1990 and 2008: 1990-1995/hierarchical mode: primary health care level organisation autonomied from hospitals. 1995-2000/ clan mode: developing of participatory managerial boards and community participation. 2000-2004/ clan mode: maturation of the "PHC movement" in competition with hospitals. 2004-2008/ clan-hierarchical mode: "movement's" crisis and constructions of norms tending towards enhancing an integrated network. Strengthening and empowering first-level health-care produced innovation favouring: the consolidation of a "PHC movement" having strong social commitment and improved services performance. The clan governance mode (regulating collective action via voluntary adhesion to shared values) was crucial for developing PHC between 1995 and 2004. Later on, the movement's fragmentation and the challenges of integrating the health system required developing hierarchical regulation mechanisms to complement the governance clan mode regulation.

    Cancer is the second cause of death in Argentina; nevertheless the distribution of the cancer incidence rates throughout the country is unknown. This study was conducted to describe cancer incidence patterns in Córdoba Province. Incidence data were supplied by the Government Córdoba Cancer Registry. Demographic information (age, sex, and place of residence) and diagnosis, certified by a pathologist, about all incident cases from June 2003 to May 2005 by type and 5-year age groups were obtained. Comparison of the incidence rate of cancer in various counties was performed by using standardized incidence rates (SIR) per 100,000 inhabitants using the world standard population. Estimated SIRs were used to build up incidence maps. Two indicators were created: sex ratio and site-specific ratio. Mixed Poisson models were fitted. Taken as a whole for all counties, SIR was 121.42 and 141.57 for men and women, respectively. The most common sites in men were prostate (13.62), lung (10.12), colon (7.53), and bladder (7.03); in women were breast (22.51) and colon (3.31). The highest and lowest rates were in urban and rural areas, respectively. Cancer registry has a pivotal role in cancer control. Such information is the primary resource of information not only for epidemiological research on cancer determinants but also for planning and evaluating health services for the policies of prevention, diagnosis and treatment of the disease.

    Person-to-person transmission of a hantavirus was first confirmed during a 1996 outbreak of hantavirus pulmonary syndrome in southern Argentina, where Andes virus is endemic. To identify other episodes of secondary transmission, we reviewed reports of 51 hantavirus infection cases from this region (November 1993–June 2005). Nine clusters involving 20 cases (39.2%) were found. Two patients, who had symptoms 3 weeks after they shared risks for rodent exposure, were considered a cluster. The other 8 clusters each began with an index case, which was almost always fatal, followed 19–40 days later by the illness of >1 person who had close and prolonged contact with the index case-patient. Person-to-person transmission was considered the probable source of these 8 clusters. The probability of initiating secondary cases was 41% for patients who died versus 4% for those who survived (p = 0.005). Interpersonal transmission of Andes virus infection should be considered even when rodent exposure cannot be definitively excluded. PMID:17370522

    Objective To investigate genetic etiologies of preterm birth (PTB) in Argentina through evaluation of single-nucleotide polymorphisms (SNP) in candidate genes and population genetic admixture. Study Design Genotyping was performed in 389 families. Maternal, paternal, and fetal effects were studied separately. Mitochondrial DNA (mtDNA) was sequenced in 50 males and 50 females. Y-chromosome anthropological markers were evaluated in 50 males. Results Fetal association with PTB was found in the progesterone receptor (PGR, rs1942836; p= 0.004). Maternal association with PTB was found in small conductance calcium activated potassium channel isoform 3 (KCNN3, rs883319; p= 0.01). Gestational age associated with PTB in PGR rs1942836 at 32 –36 weeks (p= 0.0004). MtDNA sequencing determined 88 individuals had Amerindian consistent haplogroups. Two individuals had Amerindian Y-chromosome consistent haplotypes. Conclusions This study replicates single locus fetal associations with PTB in PGR, maternal association in KCNN3, and demonstrates possible effects for divergent racial admixture on PTB.

    Electricity in Argentina is mainly supplied through the National Interconnected System (NIS) grid, that manages the generation of all medium and large size utilities (thermal, hydro and nuclear) in the country. However, there are still large areas not linked to the NIS: electricity there either comes from utilities that mainly work with diesel groups, or is obtained by individuals from 1-5 kW generators (mostly IC powered, although some wind and solar devices also exist). Finally, in many low-income rural and semi-rural sites, there is no electric generation at all. In this context, we wish to show that there is an important market niche where fuel cells should be competitive and that this market size justifies a detailed investment analysis. Thus, we have performed economic calculations in three sites, which are representative samples of different structural situations, in which costs of fuel cell produced electricity are compared to presently existing devices. Also, calculations were carried out for use of fuel cells in Antarctica.

    Clinical cases of coccidioidomycosis are rare in Argentina and are generally found in the large arid precordilleran area of the country. This study aims to perform a retrospective review of all coccidioidomycosis cases documented in the country from 1892 to 2009, and to describe those occurring in the last 4 years. One hundred and twenty eight cases were documented in the 117 year-period. Since the original description of the disease in 1892 until 1939, only 6 cases were registered; between 1940 and 1999, 59 (6-14/10 yrs) and the remaining 63 (49% of total cases) occurred in the last decade. The median age of 34 patients registered in 2006-2009 was 31 years (range: 7-89), male/female ratio was 1.3:1 and 12 patients were immunocompromised. Twenty-six cases were confirmed by direct microscopy and/or culture whereas the remaining ones by serology. All isolates were identified as Coccidioides posadasii. Thirty patients lived in a vast geographic region with epicenter in Catamarca Valley. Between 2006 and 2009, annual disease incidence rates in Catamarca Province increased from historical values below 0.5/100,000 to 2/100,000 inhabitants. Such increase suggests an emergency of coccidioidomycosis in that region.

    As part of environmental studies of the southern atmosphere, the CEILAP Lidar Division in collaboration with the Service d'Aeronomie has developed a mobile differential absorption lidar capable of making precise and accurate measurements of the stratospheric ozone. The XeCl excimer laser emission at 308 nm is used as absorbed line in the DIAL technique and an Nd-YAG laser 355 nm third harmonic is employed as a reference wavelength. Six detected channels are used for stratospheric ozone retrieval, four of them in the high and low energy of the elastically backscattered signal of the emitted wavelengths and two corresponding to the first Stokes nitrogen Raman of the emitted wavelengths. Tropospheric Water Vapor profiles using Raman channels and Aerosol Backscatter profiles are also obtained. In this paper we present a detailed description of the instrument, a discussion of data analysis and the results of the first lidar-satellite inter-comparison of stratospheric ozone profiles measured with this instrument. We also present a description of the SOLAR campaign that will be held in the 2005 southern winter-spring period in Rio Gallegos (51° 55'S, 69° 14'W) with the objective of studying the ozone layer when the polar vortex crosses over the continental part of Argentina. This campaign will be supported by JICA (Japan International Cooperation Agency).

  12. Subtyping of STEC by MLVA in Argentina

    Shiga toxin-producing Escherichia coli (STEC) causes serious human illness such as hemolytic uremic syndrome (HUS). Argentina has the world’s highest rate of this syndrome, which is the leading cause of acute renal failure among children. E. coli O157:H7 is the most common cause of HUS, but a substantial and growing proportion of this illness is caused by infection due to non-O157 strains. Multiple-locus variable-number tandem repeat analysis (MLVA) has become an established technique to subtype STEC. This review will address the use of routine STEC subtyping by MLVA in order to type this group of isolates and to get insight into the genetic diversity of native STEC. With regard to these objectives we modified and adapted two MLVA protocols, one exclusive for O157 and the other, a generic E. coli assay. A total of 202 STEC isolates, from different sources and corresponding to 20 serotypes, have been MLVA genotyped in our laboratory. In our experience, MLVA constitutes a very sensitive tool and enables us to perform an efficient STEC subtyping. The diversity found in many serotypes may be useful for future epidemiological studies of STEC clonality, applied to O157 as well as to non-O157 isolates. PMID:22919698

    Based on ethnographic research carried out in the Buenos Aires Metropolitan Area, this paper examines the views of social actors on the psychoanalytically-oriented psychotherapy focused on marginalized populations. From Foucault's perspective on the forms of truth-telling, the aim of this paper is to analyze, as a preliminary research report, treatments according to the native ways of speaking and listening, which dominate the description of therapeutic experiences of patients who come to the treatment without any professional intermediation. The neoliberal transformations of the past decades in Argentina changed both the landscape of the public health system and the daily lives of marginalized people. Considering such changes, this paper examines the ways in which verbal actions (speaking and listening) take place in psychotherapy and mark the course not only of treatments but also the temporal rhythms of their development, and their various levels of efficacy. Finally, the discussion focuses on how ways of speaking and listening in treatments are modeled not only by institutional dynamics but also by the characteristics these verbal activities take in everyday life under the logics of power that prevail over them.

    The Health Administration Agencies of many municipalities in Greater Buenos Aires (GBA) receive frequent reports on triatomines in houses. The aim of this work was to identify and describe the dispersal foci of Triatoma infestans in an urban neighborhood of GBA, and contribute to the knowledge of the epidemiological situation in the region. In June 1998, potentially infested places were entomologically evaluated. T. infestans was only detected in a hen building for egg production, which housed approximately 6,000 birds. A total of 2,930 insects were collected. Density was about 9 triatomines/m(2). The proportions of fifth instar nymphs and adults were significantly higher than those of the other stages (p<0.001). The number of triatomines collected largely exceeded the highest domestic infestation found in one house from rural endemic areas of Argentina. Though triatomines were negative for Trypanosoma cruzi, they could acquire the parasite by coming in contact with infected people living in GBA. Besides, the numerous and widely distributed places housing hens and chickens, would favor the settlement of the vector. Together, both facts may constitute a risk of parasitic vectorial transmission. It is recommended to intensify systematic activities of vector search and case detection in GBA.

    Type XIX collagen is a newly discovered member of the FACIT (fibril-associated collagens with interrupted triple helices) group of extracellular matrix proteins. Based on the primary structure, type XIX collagen is thought to act as a cross-bridge between fibrils and other extracellular matrix molecules. Here we describe the complete exon/intron organization of COL19A1 and show that it contains 51 exons, spanning more than 250 kb of genomic DNA. The comparison of exon structures of COL19A1 and other FACIT family genes revealed several similarities among these genes. The structure of exons encoding the noncollagenous (NC) 1-collagenous (COL) 1-NC 2-COL 2-NC 3-COL 3-NC 4 domain of the alpha1(XIX) chain is similar to that of the NC 1-COL 1-NC 2-COL 3-NC 3 domain of the alpha2(IX) chain except for the NC 3 domain of alpha1(XIX). The exons encoding the COL 5-NC 6 domain of alpha1(XIX) are also similar to those of the COL 3-NC 4 domain of alpha1(IX) chain. Previously, COL19A1 was mapped to human chromosome 6q12-q14, where COL9A1 is also located. Likewise, the present work shows that the mouse Col19a1 gene is located on mouse chromosome 1, region A3, where Col9a1 has also been mapped. Taken together, the data suggest that COL19A1 and COL9A1 (Col19a1 and Col9a1) were duplicated from the same ancestor gene of the FACIT family. Three CA repeat markers with high heterozygosity were found in COL19A1. These markers may be useful for linkage analysis of age-related inheritable diseases involved in eyes and/or brain.

    To characterize the mechanism of glycopeptide resistance and to determine the genetic relatedness among strains by pulsed-field gel electrophoresis (PFGE) in vancomycin-resistant Enterococcus faecium from Argentina. A total of 189 vancomycin-resistant single-patient isolates of Enterococcus faecium recovered between January 1997 and December 2000 from 30 hospitals in Argentina were studied. Minimum inhibitory concentrations were determined by the agar dilution method and van genes were detected by PCR. PFGE was used for molecular typing. All isolates except three (vanB) were of genotype vanA. For 189 vancomycin-resistant Enterococcus faecium, SmaI-PFGE indicated 35 clonal types. Most of the isolates (56%) belonged to the same clonal type 1, which was present in 19 hospitals and dominant in 17. The emergence of vancomycin-resistant Enterococcus faecium in Argentina seems to be related to the intra- and inter-hospital dissemination of an epidemic clone carrying the vanA element.

    Argentina is a country with both rich floral biodiversity and cultural diversity. Traditional herbal medicines are important in the health care of most people, and rely heavily on the use of indigenous plants. An ethnobotanical survey of the "Sierra de Comechingones" made over a 26-year period (1979-2005), indicated that 65 families and 149 different genuses were used in traditional medicines. The use of these medicines was observed to be widespread and prevalent over orthodox medicine. Medicinal native plants from this mountain range make up 31% of the total Argentina medicinal native flora. In addition, there are 15 endemic species that grow only in the region. The botanical name, popular uses, parts utilized, as well as the distribution of these medicinal plants from the "Sierra de Comechingones", Argentina, were summarized. Previous reports on phytochemical and biological activities in relation to cancer, antimicrobials and pesticides were also included.

    Sandhoff disease is a neurodegenerative, lysosomal and autosomal recessive disease caused by mutations in the HEXB gene. Three forms are recognized: infantile, juvenile and adult. Previously, an endogamous population in Córdoba, Argentina, was identified with a high incidence of Sandhoff disease, all reported cases were of the infantile type. In this work, we describe a child with the juvenile form of Sandhoff disease, the first case reported in Argentina. The patient is a 7-year-old boy presenting with ataxia, speech disturbances and global developmental delay, symptoms starting at the age of 2 years. Diagnosis was based on the hexosaminidase deficiency. Sequencing of genomic DNA revealed compound heterozygosity for two HEXB gene mutations: c.796T>G (p.Y266D) and c.1615C>T (p.R539C), both already reported. Sociedad Argentina de Pediatría.

    Meat production is extremely important for the economy of Argentina, and represents 35%-40% of all national agricultural production. Cattle are distributed throughout the country, with the highest density in the Pampa region, which hosts 66% of the national herd and produces 80% of the total meat production in Argentina. This region has a long tradition of livestock rearing, and the practice of rotation between agriculture and animal husbandry ensures an ecological equilibrium. Meat production in Argentina is based on the exploitation of natural resources, with traditional extensive grazing, which offers advantages when compared with other countries. The composition of meat depends on factors such as breed and age, and on the diet of the animals. The authors demonstrate that meat produced under extensive grazing conditions in Argentina has less intramuscular fat and cholesterol than that produced in intensive systems which have a grain-rich diet. The authors analyse the situation of the country with regard to diseases which can be transmitted by meat and which might affect public health, particularly bovine spongiform encephalopathy (BSE), brucellosis, tuberculosis, salmonellosis, campylobacteriosis, colibacillosis and taeniosis. The fact that Argentina is free from BSE is emphasised, and the prevention programmes which have been implemented to control other diseases are described. In addition, the authors discuss tests which are conducted to detect the presence of residues of chemical contaminants in meat. Emphasis is given to the quality of infrastructure, equipment and operation of the mechanised meat-processing plants, which guarantee the hygienic safety of the products. The authors conclude that meat and meat products from Argentina offer a high level of safety for consumers.

    Purpose While Argentina has significantly improved access to HIV care and antiretroviral therapy (ART) for both the general population and prisoners, the prevalence of alcohol use disorders (AUDs) among HIV-infected prisoners and their relationship to accessing ART in Argentina is currently unknown. This study aims to characterize the substance abuse patterns of HIV-infected prisoners in Argentina and to assess the independent correlates of receipt of pre-incarceration ART. Design/methodology/approach An anonymous, cross-sectional survey of 100 HIV-infected federal prisoners was conducted in the Buenos Aires municipality from July–December 2010. AUDs were assessed using the AUDIT scale. Findings A majority (63 per cent) of participants met criteria for AUDs, 45 per cent of subjects were diagnosed with HIV in prison and one-quarter had initiated ART during the current incarceration. In addition, over one-third (35 per cent) of participants did not receive ART during the pre-incarceration period despite receiving it upon incarceration. This correlated significantly with the presence of having an AUD (AOR 0.20, 95 per cent CI 0.06–0.74, p = 0.016). Practical implications AUDs are prevalent among HIV-infected prisoners in Argentina and are significantly related to negative secondary HIV prevention and treatment outcomes. While Argentina has provided an exemplary model of HIV-related health care reform within its prisons, future efforts to provide screening and treatment for AUDs are needed to improve the health of the nation’s incarcerated population. Originality/value This paper is the first to describe pre-incarceration drug and alcohol use disorders and issues related to access to ART among prisoners in Argentina. PMID:24772187

    It was with great pleasure that the Department of Nuclear and Theoretical Physics of the University of Pavia and the INFN (Istituto Nazionale di Fisica Nucleare) Structure of Pavia organised the XIX Nuclear Physics Divisional Conference of the European Physical Society, which was held in the historical buildings of the University of Pavia from 5-9 September 2005. The Conference was devoted to the discussion of the most recent experimental and theoretical achievements in the field of Nuclear Physics applications, as well as of the latest developments in technological tools related to Nuclear Physics research. The University of Pavia has a long tradition in Physics and in Applied Physics, being the site where Alessandro Volta developed his "pila", the precursor of the modern battery. This is the place where the first experiments with electricity were conducted and where the term "capacitance" used for capacitors was invented. Today the University hosts a Triga Mark II nuclear reactor, which is used by the Departments of the University of Pavia and by other Universities and private companies as well. Moreover, Pavia is the site selected for the construction of the CNAO complex "Centro Nazionale di Adroterapia Oncologica" (National Centre for Oncological Hadrontherapy), planned for 2005-2008 which represents a unique facility in Italy and will be among the first complexes of this type in Europe. The Conference has gathered together experts in various fields from different countries and has been the occasion to review the present status and to discuss the new emerging trends in Nuclear Physics and its applications to multidisciplinary researches and the development of new technologies. The following topics were treated: Nuclear Techniques in Medicine and Life Sciences (Cancer Therapy, new Imaging and Diagnostics Tools, Radioisotope production, Radiation Protection and Dosimetry). Applications of Nuclear Techniques in Art, Archaeometry and other Interdisciplinary fields

    Cryptosporidiosis is observed in reptiles with high morbidity and considerable mortality. The objective of this study was to achieve the molecular identification of Cryptosporidium spp. in pet leopard geckos (Eublepharis macularius) from a breeder colony in Buenos Aires, Argentina. Oocysts comparable to those of Cryptosporidium spp. were detected in three geckos with a history of diarrhea, anorexia and cachexia. Molecular identification methods confirmed the presence of Cryptosporidium varanii (syn. C. saurophilum). This agent was considered to be the primary cause of the observed clinical disease. This is the first description of C. varanii infection in pet reptiles in Argentina.

    In Argentina, the construction, operation, and use of research and radioisotope production reactors is and has been an important method of personnel preparation for the nuclear power program. Moreover, it is a very suitable means for technology transfer to countries developing their own nuclear programs. At present, the following research reactors are in operation in Argentina: Argentine Reactor 0 (RA-0); Argentine Reactor 1 (RA-1); Argentine Reactor 2 (RA-2); Argentine Reactor 3 (RA-3); Argentine Reactor 4 (RA-4). The Argentine Reactor 6 (RA-6), under construction, should reach criticality in 1981.

    Una virus (UNAV), Togaviridae family, is widely distributed in South America, where infections have been detected in mosquitoes and vertebrate hosts (humans, birds and horses). We analyzed human sera from Córdoba inhabitants aged 44 to 89 years and using a neutralization test, we found a prevalence of UNAV antibodies of 3.8% (3/79). The low titers detected suggest past infections probably acquired in rural areas of the Province of Córdoba (central Argentina). None sera were found positive for MAYV neutralizing antibodies. This is the first report of human infections by UNAV in Argentina.

    We performed a study on the notes made by doctor Antonio Alfaro to the book by Bichat and Desault "Treaty of urinary tract diseases". Such notes are altogether more extensive than the work they accompany. In them we see the knowledge about the treatment of urinary tract diseases in the beginning of the XIX century had a great level and, at least, similar to that of other European countries. The notes are accompanied by multiple references to surgeons of various times, and publications of that time. All them conform a real Urology text with its own personality. Dr. Antonio Alfaro must be among the Spanish urological medical literature authors of the 19th Century.

    Calculated spectra of the ions Fe XIX-XXII for various densities and temperatures are presented, thereby extending the work begun by Doschek, Feldman, and Cowan (1981). The calculations are based on a code (the Cowan code) that computes both the level structure of an ion and intensity factors for the 1s-2p satellite lines. A comparison is made between the calculated spectra and those observed in solar flares by the P78-1 and SMM instruments. The observed intensities of Fe XX lines, which are the most sensitive to density, are found to agree well with those calculated in the low-density limit. The agreement for lines arising from other ions is also very good. It is also seen that the predicted density variations in Fe XX are confirmed by the higher density Princeton Large Torus plasmas. Thus a possible useful density diagnostic is indicated for tokamak and high-density astrophysical plasmas, perhaps including some solar flares.

    Background Cardiovascular disease (CVD) is the leading cause of death in adults in Argentina. Sodium reduction policies targeting processed foods were implemented in 2011 in Argentina, but the impact has not been evaluated. The aims of this study are to use Argentina-specific data on sodium excretion and project the impact of Argentina’s sodium reduction policies under two scenarios - the 2-year intervention currently being undertaken or a more persistent 10 year sodium reduction strategy. Methods We used Argentina-specific data on sodium excretion by sex and projected the impact of the current strategy on sodium consumption and blood pressure decrease. We assessed the projected impact of sodium reduction policies on CVD using the Cardiovascular Disease (CVD) Policy Model, adapted to Argentina, modeling two alternative policy scenarios over the next decade. Results Our study finds that the initiative to reduce sodium consumption currently in place in Argentina will have substantial impact on CVD over the next 10 years. Under the current proposed policy of 2-year sodium reduction, the mean sodium consumption is projected to decrease by 319–387 mg/day. This decrease is expected to translate into an absolute reduction of systolic blood pressure from 0.93 mmHg to 1.81 mmHg. This would avert about 19,000 all-cause mortality, 13,000 total myocardial infarctions, and 10,000 total strokes over the next decade. A more persistent sodium reduction strategy would yield even greater CVD benefits. Conclusion The impact of the Argentinean initiative would be effective in substantially reducing mortality and morbidity from CVD. This paper provides evidence-based support to continue implementing strategies to reduce sodium consumption at a population level. PMID:24040085

    The authors in the introduction provide an schematic historical scope of reference about the spaniard and european psychiatry from the XVIIIe to the XIXe century. They described the first seven clinical cases of Delirium found by them and published by spaniard physicians in the first half of the XIXe century. They revised mainly the clinical sintomatology, course and evolution, and went into deep detail in the hygienic-dietetical and pharmacological therapeutics used in this period, specially several galenic preparations of opium, tartarus emeticus, cremor, etc. Serapio Escolar y Morales (1808-1874) described the first clinical case of Delirium Tremens in 1839 in a 28 year old man, raising the differential diagnosis between intermittent fever, epilepsy and meningitis, and proposed a useless antiflogistic treatment (bleeding, leeches, poultice) and opium. The second case was described by an anonymous author (J.M.S.Z.) in 1845 in a 42 year old man. Francisco Castellvi y Pallares (1812-1879), in 1845, published another case in a 34 year old male, with an adequate description of the natural history of the disease, healing in 19 days with high doses of watery opium extract. The fourth clinical case was described by R.C.B. in 1846 in a 60 year old man with "alcoholic chorea", "ataxis fever" being the only one with a mortal outcome, treated also with opiates which he did not agree with. The fifth and sixth cases were published by Uliberry in 1847 in two males, 38 and 36 years old respectively. The seventh and last case was described in 1848 by F. Paula Barea, having to highlight the nosological, nosographical and evolutive perspectives in 3 clinical periods and a fourth of convalescence, the treatment differences and the etiopathogenical considerations. Included are 9 tables, 2 graphics and 29 bibliographical references.

    This article presents the experimental results of a research on six manuscripts (three of the XVIII century and three of XIX century) belonging collection of old religious books to the Moldovan Metropolitan Church of Romania. Non-invasive techniques (optical microscopy [OM], scanning electron microscopy/energy dispersive X-ray system, X-ray fluorescence analysis, shrinkage temperature, and Fourier transform infrared spectroscopy/attentuated total reflectance) provided information on the degree of degradation and identification of the leather bookbinding type. Moreover, visual assessment and OM revealed the extent of the surface degradation (wane, biological attack, change color, etc.). The degradation extent of the skin bindings was determined on the 12 samples. The insight on the mechanism of degradation was accomplished by analyzing the deterioration of collagen fibers in terms of shrinkage temperature and chemical modifications induced by oxidative and hydrolytic processes. Shrinkage temperature values were lower compared with the literature data for collagen, indicating that the leather bookbinding suffered intrinsic damage. Morphological analysis was accomplished by microscopy and allowed the identification of skin type and provided information about its processing technique. Mineral elements were identified for leather composition and contributed to the information regarding the origin and the extent of degradation of the leather bookbinding, of the studied manuscripts. The analyzed results were useful in determining the state of preservation and were able to provide an increased efficiency of further restoration. The correlation of the obtained data brought new contributions to the knowledge of the leather covers for the book technique in the XVIII and XIX centuries in monastic workshops of Eastern Europe. © 2014 Wiley Periodicals, Inc.

  14. Element fluxes from Copahue Volcano, Argentina

    NASA Astrophysics Data System (ADS)

    Varekamp, J. C.

    2003-12-01

    Copahue volcano in Argentina has an active volcano-magmatic hydrothermal system that emits fluids with pH=0.3 that feed a river system. River flux measurements and analytical data provide element flux data from 1997 to 2003, which includes the eruptive period of July to December 2000. The fluids have up to 6.5 percent sulfate, 1 percent Cl and ppm levels of B, As, Cu, Zn and Pb. The hydrothermal system acts as a perfect scrubber for magmatic gases during the periods of passive degassing, although the dissolved magmatic gases are modified through water rock interaction and mineral precipitation. The magmatic SO2 disproportionates into sulfate and liquid elemental sulfur at about 300 C; the sulfate is discharged with the fluids, whereas the liquid sulfur is temporarily retained in the reservoir but ejected during phreatic and hydrothermal eruptions. The intrusion and chemical attack of new magma in the hydrothermal reservoir in early 2000 was indicated by strongly increased Mg concentrations and Mg fluxes, and higher Mg/Cl and Mg/K values. The hydrothermal discharge has acidified a large glacial lake (0.5 km3) to pH=2 and the lake effluents acidify the exiting river. Even more than 100 km downstream, the effects of acid pulses from the lake are evident from red coated boulders and fish die-offs. The river-bound sulfate fluxes from the system range from 70 to 200 kilotonnes/year. The equivalent SO2 output of the whole volcanic system ranges from 150 to 500 tonnes/day, which includes the fraction of native sulfur that formed inside the mountain but does not include the release of SO2 into the atmosphere during the eruptions. Trace element fluxes of the river will be scaled up and compared with global element fluxes from meteoric river waters (subterranean volcanic weathering versus watershed weathering).

    The San Jorge basin, although small, is the most important hydrocarbon-producing basin in Argentina. Remaining untested potential is high because of the presence of good source rock, favorable structural complexity, and multiple reservoirs. Reservoir quality is commonly low because of the highly tuffaceous sandstones. The sedimentary fill of the basin is closely related to its tectonic history. Northwest-southeast-trending grabens formed and filled during a Triassic and Early Jurassic early rift phase, climaxing with a pervasive Middle Jurassic volcanic episode; continued growth and filling of the basin occurred during a Late Jurassic-earliest Cretaceous late rift phase and Cretaceous early and late sag phases. Late Cretaceous-early Tertiary extension set up many of the present-day structural traps along normal faults. Middle Tertiary Andean compression produced the narrow, north-south San Bernardo structural belt, which exhibits reversed movement on older, normal, graben-bounding faults and on local, low-angle thrust faults. Marked early to middle Tertiary erosion produced a significant unconformity within Cretaceous beds around basin margins. Origin of Upper Jurassic and lowermost Cretaceous sedimentary fill is primarily lacustrine or fluvial in origin. Lacustrine, organic-rich black shales are fringed by oolitic and other limestones and fluvial-deltaic sandstones derived mostly from the north. A significant southern source of sand existed during the Valanginian. Interbedded marine shales occur mostly to the west toward a presumed marine seaway connection to the northern Magallanes basin. Middle to Upper Cretaceous sedimentary rocks, sourced mostly from the north, are mainly fluvial sandstone-shale successions with some minor lacustrine influence. Reservoir quality glauconitic sands were deposited during a Late Cretaceous-early Tertiary marine incursion from the Atlantic.

The Campo del Cielo meteorite field consists, at least, of 20 meteorite craters with an age of about 4000 years. The impactor was an Iron-Nickel asteroid ( Type meteorite IA ) and plenty of meteorite specimens survived the impact. Impactor's diameter is estimated 5 to 20 meters. Craters and meteorite fragments are widespread in an oval area of 18.5 X 3 km. ( SW-NE ). 3) RIO CUARTO , Cordoba Province. ( S32o52' W64o14' ) Rio Cuarto Craters are, at least, 11 oblong structures ranging in size from `Crater' `A' of 4,5 X 1,1 Km., down to structures several meters wide. They are aligned in parallel in a NE-SW direction and they span a line of about 30 km.. These oval depressions resemble the structures produced in high speed gun laboratory experiments of low angle impacts. Recently, by satellite imagery survey, more than 400 new features that bear a strong similarity to those previously described were reported.The situation is unclear and the area demands more research. 4) SOUTH ATLANTIC GEOPHYSICAL ANOMALY Although very speculative, a possible multi-ring basin impact structure has been proposed to be in the Patagonian continental Shelf NW of Falkland/Malvinas Islands in front of Santa Cruz Province.

  17. Analysis of cattle movements in Argentina, 2005.

    2011-02-01

    We describe the movement of cattle throughout Argentina in 2005. Details of farm-to-farm and farm-to-slaughter movements of cattle were obtained from the Sanitary Management System database (Sistema de Gestión Sanitaria, SGS), maintained by the National Service for Agrifood Health and Quality (SENASA). Movements were described at the regional and district level in terms of frequency, the number of stock transported, the district of origin and destination and Euclidean distance traveled. Social network analysis was used to characterize the connections made between regions and districts as a result of cattle movement transactions, and to show how these characteristics might influence disease spread. Throughout 2005 a total of 1.3 million movement events involving 32 million head of cattle (equivalent to approximately 57% of the national herd) were recorded in the SGS database. The greatest number of farm-to-farm movements occurred from April to June whereas numbers of farm-to-slaughter movement events were relatively constant throughout the year. Throughout 2005 there was a 1.1-1.6-fold increase in the number of farm-to-farm movements of cattle during April-June, compared with other times of the year. District in-degree and out-degree scores varied by season, with higher maximum scores during the autumn and winter compared with summer and spring. Districts with high in-degree scores were concentrated in the Finishing region of the country whereas districts with high out-degree scores were concentrated not only in the Finishing region but also in Mesopotamia, eastern Border and southern Central regions. Although movements of cattle from the Border region tended not to be mediated via markets, the small number of districts in this area with relatively high out-degree scores is a cause for concern as they have the potential to distribute infectious disease widely, in the event of an incursion.

    The detection of metabolic syndrome (MS) is use ful for identifying individuals at risk for type 2 diabetes and coronary heart disease. The objectives of the study were to describe the prevalence of MS in employees 40-65 years old, utilizing different definitions and to analyze the relation with educational level and gender by means of cross-sectional and multicenter study of different regions of Argentina. Compared MS definitions were: International Diabetes Federation, American Heart Association/National Heart, Lung and Blood Institute and National Cholesterol Education Program - Adults Treatment Panel III. Fulfilled the protocol 2806 cases. It was observed a prevalence of 0.31, 0.30 and 0.26 respectively, more frequent in men (p = 0.0000). There was no significant difference between sexes in the group 60 to 65 years old. After adjusting to age, sex, physical activity, family history of diabetes and menopause, the women with low educational level (<12 years) had more risk than men, OR = 1.95 (CI 95% 1.49-2.55) p = 0.000 compared with OR = 1.36 (CI 95% 1.10-1.69) p = 0.005, respectively. The low educational level in women, adjusted for confounders, was a predictor of four components of MS: central obesity, low C-HDL, glucose > or =100 mg/dl and hypertriglyceridemia; in men was only a hard predictor of hypertriglyceridemia. The results alert about the need of education of the population for the control of risk factors and adoption of healthy habits.

  19. Diarrhea and parasitosis in Salta, Argentina.

    2009-03-01

    Salta city is the capital of the province with the same name located in the northwest of Argentina. Its great growth over the last decade was not organized and the population expanded to occupy places where water and sanitation were not yet available. Although the Arenales River, crossing the city, receives the impact of point and non-point source pollution, the water is used for many purposes, including domestic in the poorest areas, industrial, and recreational with children as the main users. According to the World Health Organization, an estimated 24% of the global disease burden and 23% of all deaths can be attributed to environmental factors. In particular, an estimated 94% of the diarrheal burden of disease is attributable to environment, and is associated with risk factors such as unsafe drinking water and poor sanitation and hygiene. Chronic diarrhea can be caused by an infection or other etiologies; however, most of the times the etiological agent is not identified. All the cases of diarrhea and parasitosis reported during 2005 in four public health centers of the city of Salta were classified by gender and age, analyzed, and represented geographically to show areas of higher morbidity rates, which were probably related to environmental factors. Water, poor sanitation, and pollution are candidate risk factors. Diarrhea cases showed seasonality, with the highest incidence during late spring and summer, while parasitosis was persistent throughout the year. Our spatial analysis permitted us to detect the regions of higher incidence of diarrhea and parasitosis during 2005 in the area of study.

  20. Hepatitis C in Argentina: epidemiology and treatment

    2014-01-01

    Hepatitis C is the leading cause of chronic hepatitis, cirrhosis, and liver cancer in Argentina, where from 1.5% to 2.5% of adults are infected. Most of the infections were acquired 30–50 years ago. It is estimated that more than half of infected individuals are not aware of their infection. Even though the prevalence in blood donors has decreased to 0.45% at present, many high-prevalence populations still exist, where the reported prevalence ranges from 2.2% to 7.1%. Therapy is recommended for patients with fibrosis, in order to prevent disease progression, hepatic decompensation, and hepatocellular carcinoma. Great advances were achieved in the treatment of genotype 1 infection since the development and release of boceprevir and telaprevir. When either of these protease inhibitors is associated with peginterferon plus ribavirin, the sustained virological response (SVR) rate improves from 40%–50% to 67%–75%. For genotype 2 and 3 infection, treatment with peginterferon plus ribavirin is still the standard of care, with SVR rates of 70%–90%. There are significant new antivirals in development, and some of them are close to being released. These drugs will most likely be the future standard of care for all genotypes, and will be incorporated in better-tolerated and highly effective all-oral regimes. The impact that these new therapies might have in health-related economics is unpredictable, especially in developing countries. Each country must carefully evaluate the local situation in order to implement proper screening and treatment programs. Difficult-to-treat patients, such as those with decompensated cirrhosis, patients in hemodialysis, and those with other significant comorbidities, might not be able to receive these new therapeutic approaches and their management will remain challenging.

    To ascertain lifetime prevalence of positivity to a screening questionnaire for bipolar disorders (BD) in Sardinian immigrants to Argentina and residents of Sardinia and assess whether such positivity affects quality of life (QoL) in either group. Our hypothesis is that screen positivity for BD may be more frequent in immigrants. Observational study. Subjects were randomly selected from the membership lists of associations of Sardinian immigrants in Argentina. A study carried out in Sardinia using the same methodology was used for comparison. The Mood Disorder Questionnaire was used to screen for mania/hypomania and the Short-Form Health Survey-12 to measure QoL. A higher prevalence of manic/hypomanic episodes was found in Sardinian immigrants to Argentina (p < 0.0001; odds ratio = 3.0, 95% confidence interval 1.87-4.77). Positivity at screening was associated with a lower QoL both in Sardinian immigrants to Argentina and in residents of Sardinia. To the best of our knowledge, this is the first study to show a higher lifetime prevalence of manic/hypomanic episodes in a general-population sample of individuals who migrated to a foreign country. Our results are in agreement with the hypothesis that hyperactive/novelty-seeking features may represent an adaptive substrate in certain conditions of social change.

    2013-07-16

    The objective of this review was to revise the existing information regarding type 2 diabetes (T2D) prevalence in the Argentine population during the past 30 years and to see whether the available data and methodology of the studies conducted allow analysis of time trends. The PubMED and LILACS databases were searched using the search terms "diabetes prevalence" and "Argentina". A total of 301 studies were identified and 19 of them remained in the review after applying the inclusion and exclusion criteria. The studies reviewed covered a time period of 30 years (1979-2012). The studies conducted in Argentina during the last 30 years assessing the prevalence of T2D are very heterogeneous. The majority of the studies were conducted in the province of Buenos Aires. As the assessment of T2D varied between the studies in respect of diagnostic criteria and diagnostic tests for T2D, meaningful comparisons are difficult to make, not to mention an analysis of time trends. All in all, the T2D prevalence seems to be at least 10% in the Argentina population. However, the latest large population surveys conducted in Argentina is promising and may offer the most reliable estimates of the T2D prevalence even though the diagnosis of T2D was based on participant self-report.

    2005-09-01

    In order to study the isonymic structure of Argentina, the surname distributions of 22.6 million electors registered for the year 2001 were analyzed in the 24 districts (distritos) and 541 municipalities (municipios) of the country. The number of different surnames found was 414,441. Matrices of isonymic distances between districts were constructed and tested for correlation with the geographic distance between the capital towns of the districts. We found that, for the whole of Argentina, Euclidean distance was correlated with the log of geographic distance (r=0.480+/- 0.067). A dendrogram of the 24 regions was built from the matrix of Euclidean distances, using the UPGMA method. The clusters identified by the dendrogram are coincident with conterminous geographical regions of the country. Random inbreeding calculated from isonymy, F(ST), was highest in La Rioja, Corrientes, and Santiago del Estero. It was lowest in the area of Buenos Aires and in the north-central region of Santa Fé. Average Fisher's alpha for municipalities was 358; for districts, it was 422; and for Argentina as a unit, it was 602. The geographical distribution of alpha in 541 municipalities, high in the east and lower in the west of the country, is compatible with the settlement in the 20th century of subsequent waves of immigrants moving from the North Atlantic coast toward the foot of the Andes and toward the south. The present structure of Argentina indicates that migration dominates over drift. (c) 2005 Wiley-Liss, Inc.

    Kotsias, Basilio A

    2011-01-01

    The aim of this paper was to provide quantitative data about clinical investigation in Argentina. We searched MEDLINE which is the U.S. National Library of Medicine's bibliographic database that contains more than 18 million references to journal articles in life sciences; 5400 journals in 39 languages are listed. In 2009 almost 850,000 papers were cited in MEDLINE and Argentina provided 0.33% of them, 90% of these in English. The number of papers published in Spanish is diminishing every year and similar results are observed with the German, French and other languages. Using the tools provided by MEDLINE we searched for papers that could be classified as clinical. We restricted our search to the word "patients" in the text and "hospital" in the address provided by the authors. Along the last 10 years, from 2000 to 2009, about 16% of the papers published from Argentina contain the word "patient" and this percentage is reduced to half if we combine the word "patient" with the word "hospital" in the address. If we search for papers written in Spanish with these two restrictions the number is much lower. The number of articles from Argentina followed the upward trend in the total of articles cited in MEDLINE in the last 10 years. This local increase was due to basic investigation papers because the percentage of clinical articles was relatively constant during these years. In conclusion, these data provide a survey of an area with scanty quantitative information.

    1995-10-01

    Human T-cell lymphotropic virus type I (HTLV-I) is associated with adult T-cell leukaemia/lymphoma (ATLL) and tropical spastic paraparesis (TSP/HAM) in endemic and non-endemic areas. Serological studies have shown that HTLV-I is prevalent in some Latin American countries such as Brasil, Chile, Colombia, Perú and Uruguay. We describe here the clinical and laboratory features of five cases of ATLL diagnosed in Argentina. All patients (4 males, 1 female; median age 48.2 years) were of caucasian origin; 4 born in Argentina and 1 in Chile. High risk factors for HTLV-I infection were not apparent in Argentina patients, whereas the Chilean resident, who was a promiscuous heterosexual, travelled through Chile frequently. Positive results for antibodies to HTLV-I were detected in all five cases and in some of their relatives. This report suggests that HTLV-I infection may be endemic in, Argentina where TSP has also been described.

    The Order Siphonaptera comprises cosmopolitan haematophagous ectoparasites of birds and mammals. More than ten years have past since the last list of species known for Argentina. Herein we provide a review of the fleas from the country, which includes an updated list, host species and geographical distribution for each taxa, as well as some comments. We report 127 species and subspecies belonging to eleven different families; 42 of these species are endemic. Four genera (Adoratopsylla, Cleopsylla, Ctenidiosomus, and Nonnapsylla) and six species and subspecies (Adoratopsylla (Adoratopsylla) antiquorum antiquorum, Agastopsylla pearsoni, Polygenis (Polygenis) roberti beebei, Plocopsylla (Plocopsylla) silewi, Plocopsylla (Plocopsylla) wilesi and Tunga terasma) are added to the list for Argentina. Nine species new to science are included, described on the bases of specimens collected from Argentina (Ctenidiosomus austrinus, Ectinorus (Ectinorus) lareschiae, Ectinorus (Ectinorus) spiculatus, Ectinorus (Ectinorus) morenoi, Hectopsylla narium, Plocopsylla (Plocopsylla) linardii, Neotyphloceras crackensis, Neotyphloceras pardinasii and Tunga perforans). Information provided herein contributes to the knowledge of the fleas from Argentina, necessary to a better understanding of their role as parasites themselves and vectors of zoonotic importance.

    Neural tube defects (NTDs) are the most common congenital anomalies of the central nervous system. Prevalence of NTDs varies depending on geographic region and folic acid fortification. The main objectives of this study are to analyze the prevalences of NTDs reported to the National Registry of Congenital Anomalies of Argentina (RENAC) during the period 2009 to 2013, to compare them with data from other selected surveillance systems of the Americas, and to evaluate the impact of folic acid fortification on the prevalence of NTDs in Argentina. We analyzed changes in prevalence between 2009 and 2013 for the RENAC, and differences in prevalence between RENAC and other surveillance systems. We evaluated changes for the pre and postfortification time periods in Argentina. In Argentina, anencephaly and spina bifida showed no statistically significant variation between 2009 and 2013, and encephalocele showed a statistically significant decline. The RENAC showed a statistically significant higher prevalence for all three defects when compared with surveillance systems from Chile, Colombia, and Costa Rica, and a statistically significant lower birth prevalence than Cuba for anencephaly. No differences were observed when comparing it to the Atlanta-USA and Mexico systems. A significant decrease in prevalence was observed for all three anomalies for the postfortification period in Argentina. The characteristics of cases reported to the RENAC are similar to those already reported in the literature. The differences in prevalence between the RENAC and other surveillance systems could be artifactual or real. We confirmed the decrease of prevalence of NTDs after folic acid fortification. © 2015 Wiley Periodicals, Inc.

  3. A magnetoclimatological investigation of Pampean loess, Argentina

    NASA Astrophysics Data System (ADS)

    2005-01-01

    Magnetic susceptibility has proved to be a very useful tool for understanding Northern Hemisphere loess/palaeosol sequences, both for intersite correlation and for broad climatic interpretation. However, there are two competing magnetoclimatological models that predict completely opposite patterns of variability-the so-called wind-vigour and pedogenic models. In the former, stronger winds during glacial intervals entrain larger quantities of dense magnetic particles than during interglacials. Glacial loess is therefore more magnetic than interglacial palaeosol (e.g. Kurtak, Siberia). In the pedogenic model, biological and/or chemical processes lead to the neo-formation of magnetic material so that palaeosols are more magnetic than pristine parent loess (e.g. the Chinese Loess Plateau). We are currently extending our investigation of loess/palaeosol sequences to the Southern Hemisphere starting with a new 13 m section in the El Cristo quarry in the city of La Plata, Buenos Aires Province, Argentina. The magnetic susceptibility profile shows a clear sequence of maxima and minima that correspond to lithological variations, but interpretation of these correlations is not straightforward. In the top 4 m of the section, parent material (loess) has high susceptibility whereas palaeosols have low values, consistent with the wind-vigour model. The same pattern is seen for most of the remaining 9 m of section, but there are intervals where gleying has occurred, particularly between depths of 8 and 10 m. Under the waterlogged conditions implied, iron oxides are likely to be removed and any original magnetoclimatological signal is lost (or at least strongly modified). A further complication arises from the measured values of the frequency dependence of susceptibility, which is usually taken to indicate the presence of ultrafine magnetic particles produced during pedogenesis. The El Cristo values fall squarely in between those observed in Siberia and China. An important

    This topographic image of Patagonia, Argentina shows a spectacular landscape formed by volcanoes, rivers, and wind. The area is located just east of the narrow range of the Andes Mountains, about 100 kilometers (62 miles) east of the border with Chile. Interesting features include basalt-capped mesas with sinkholes (lower center), arcuate ridges of windblown beach sands downwind from a salty desert lake (upper center), young volcanic cones(right), and at least one case of what geologists call 'inverted relief'. This happens when lava flows down a valley in soft material and then the soft material is eroded away leaving the former valley as a ridge of lava. These ridges can be seen on the slopes of the volcano in the upper right. Geologists will use SRTM topographic data to study the interaction of volcanic, climatic and erosional processes.

    This shaded relief image was generated using topographic data from the Shuttle Radar Topography Mission. A computer-generated artificial light source illuminates the elevation data to produce a pattern of light and shadows. Slopes facing the light appear bright, while those facing away are shaded. On flatter surfaces, the pattern of light and shadows can reveal subtle features in the terrain. Colors show the elevation as measured by SRTM. Colors range from blue at the lowest elevations to white at the highest elevations. This image contains about 1100 meters(3600 feet) of total relief. White speckles on the face of some of the mountains are holes in the data caused by steep terrain. These will be filled using coverage from an intersecting pass.

    The Atlantic Forest represents one of the global priority eco-regions for biodiversity conservation. In Argentina, this is represented by the Paranense Forest, which occupies much of the Misiones Province. In this paper, an updated list of land mollusks from Misiones Province is presented, and its species richness was evaluated comparing protected and unprotected areas. For this, we reviewed La Plata Museum Mollusk Collection, updated the literature review, and developed some field work between 2009 and 2010. For the areographic work, a grid (50 x 50 km) was applied to a Misiones province map. In this region, large areas of native vegetation constituting the Paranaense Forest still persist, and include protected areas such as the Iguazú National Park and Puerto Peninsula Provincial Park. These areas have been the most explored at the malacological level (both terrestrial and aquatic environments), a fact that is consistent with the greater number of records found, which may also be the explanation for the highest number of species recorded in the region. A database containing 497 records was compiled. The number of species occurring in this Province was increased from 28 to 56; 11 of which were exotic species. A total of 38 of the species occurred in protected areas and 53 in unprotected areas; and 25 species were micro-mollusks. Orthalicidae was the family with the highest species number (10) and the widest distribution, occupying 16/20 sampling units. Megalobulimus was the genus found in a greater number of sampling units (14/20). The highest values of specific richness of land gastropods were found in Northern Misiones (R=32). This richness was similar to that previously reported for the Tucumán Province, although species occurring in both provinces were mostly different. The richness in Misiones Province border areas, as the Republic of Paraguay and the state of Santa Catarina (Brazil), was about twice that found in the province. The present study showed the

    2001-01-01

    This anaglyph of an area south of San Martin de Los Andes, Argentina, is the first Shuttle Radar Topography Mission (SRTM) view of the Andes Mountains, the tallest mountain chain in the western hemisphere. This particular site does not include the higher Andes peaks, but it does include steep-sided valleys and other distinctive landforms carved by Pleistocene glaciers. Elevations here range from about 700 to 2,440 meters (2,300 to 8,000 feet). This region is very active tectonically and volcanically, and the landforms provide a record of the changes that have occurred over many thousands of years. Large lakes fill the broad mountain valleys, and the spectacular scenery here makes this area a popular resort destination for Argentinians.

    This anaglyph was produced by first shading a preliminary SRTM elevation model. The stereoscopic effect was then created by generating two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of Earth's surface in its full three dimensions. Anaglyph glasses cover the left eye with a red filter and cover the right eye with a blue filter.

    Elevation data used in this image was acquired by the Shuttle Radar Topography Mission aboard Space Shuttle Endeavour, launched on February 11,2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense (DoD), and the German and Italian space agencies.

    The article describes the system of conceptions about subject of investigation in medicine and methods of research activities of physicians well-established by early 70s of XIX century. It is postulated that in the middle of 1870s in medicine occurred an objective need of entirely different from before vision of investigated reality, development and implementation of fundamentally new methodological approaches to its studying that by-turn initiated global scientific revolution in medicine of the last quarter of XIX-first half of XX centuries. It is substantiated that need of new vision of investigated reality became first of all a consequence of profound intra-disciplinary crisis related to awareness of fallibility of existed ideas of human organism and its vital activity. The second cause is two "paradigm inoculations" from biology which resulted in forced acceptance by physicians the extreme incompleteness and fallacy of their previous views concerning environment and essence of its effect on human organism.

    Reently calculated collision strengths, including relativistic and resonance effects, are employed to compute Maxwellian averaged collision strengths for 78 transitions involving states of principal quantum numbers 2-1 and 3-1 in Ca XIX and Fe XXV. These rate parameters are tabulated at temperatures of interest in astrophysical and labortory plasmas with radiation in the hard X-ray wavelength range. For some transitions, significant differences are found with the earlier calculations of Pradhan, Norcross, and Hummer (1981).

  10. Stereo Pair: Basalt Cliffs, Patagonia, Argentina

    NASA Technical Reports Server (NTRS)

    2000-01-01

    Basalt cliffs along the northwest edge of the Meseta de Somuncura plateau near Sierra Colorada, Argentina show an unusual and striking pattern of erosion. Stereoscopic observation helps to clarify the landform changing processes active here. Many of the cliffs appear to be rock staircases that have the same color as the plateau's basaltic cap rock. Are these the edges of lower layers in the basalt or are they a train of slivers that are breaking off from, then sliding downslope and away from, the cap rock. They appear to be the latter. Close inspection shows that each stair step is too laterally irregular to be a continuous sheet of bedrock like the cap rock. Also, the steps are not flat but instead are little ridges, as one might expect from broken, tilted, and sliding slices of the cap rock. Stream erosion has cut some gullies into the cliffs and green vegetation shows that water springs from and flows down some channels, but landsliding is clearly a major agent of erosion here.

    This cross-eyed stereoscopic image pair was generated using topographic data from the Shuttle Radar Topography Mission, combined with an enhanced Landsat 7satellite color image. The topography data are used to create two differing perspectives of a single image, one perspective for each eye. In doing so, each point in the image is shifted slightly, depending on its elevation. When stereoscopically merged, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions.

    Landsat satellites have provided visible light and infrared images of the Earth continuously since 1972. SRTM topographic data match the 30-meter (99-foot) spatial resolution of most Landsat images and provide a valuable complement for studying the historic and growing Landsat data archive.

    NASA Technical Reports Server (NTRS)

    2001-01-01

    Volcanism and erosion are prominently seen in this view of the eastern flank of the Andes Mountains taken by Shuttle Radar Topography Mission (SRTM). The area is southeast of San Martin de Los Andes, Argentina. Eroded peaks up to 2,210-meter-high (7,260-foot) are seen on the west (left), but much of the scene consists of lava plateaus that slope gently eastward. These lava flows were most likely derived from volcanic sources in the high mountains. However, younger and more localized volcanic activity is evident in the topographic data as a cone surrounding oval-shaped flow near the center of the scene.

    The plateaus are extensively eroded by the Rio Limay (bottom of the image) and the Rio Collon Cura and its tributaries (upper half). The larger stream channels have reached a stable level and are now cutting broad valleys. Few terraces between the levels of the high plateaus and lower valleys (bottom center and upper right of the volcanic cone) indicate that stream erosion had once temporarily reached a higher stable level before eroding down to its current level. In general, depositional surfaces like lava flows are progressively younger with increasing elevation, while erosional surfaces are progressively younger with decreasing elevation.

    This anaglyph was produced by first shading a preliminary SRTM elevation model. The stereoscopic effect was then created by generating two differing perspectives, one for each eye. When viewed through special glasses, the result is a vertically exaggerated view of the Earth's surface in its full three dimensions.

    2000-01-01

    In addition to an elevation model of most of Earth'slandmass, the Shuttle Radar Topography Mission will produce C-band radar imagery of the same area. This imagery is essentially a 10-day snapshot view of the Earth, as observed with 5.8 centimeter wavelength radar signals that were transmitted from the Shuttle, reflected by the Earth, and then recorded on the Shuttle. This six-image mosaic shows two examples of SRTM radar images (center) with comparisons to images acquired by the Landsat 7 satellite in the visible wavelengths (left) and an infrared wavelength (right). Both sets of images show lava flows in northern Patagonia, Argentina. In each case, the lava flows are relatively young compared to the surrounding rock formations.

    In visible light (left) image brightness corresponds to mineral chemistry and -- as expected -- both lava flows appear dark. Generally, the upper flow sits atop much lighter bedrock, providing good contrast and making the edges of the flow distinct. However, the lower flow borders some rocks that are similarly dark, and the flow boundaries are somewhat obscured. Meanwhile, in the radar images (center), image brightness corresponds to surface roughness (and topographic orientation) and substantial differences between the flows are visible. Much of the top flow appears dark, meaning it is fairly smooth. Consequently, it forms little or no contrast with the smooth and dark surrounding bedrock and thus virtually vanishes from view. However, the lower flow appears rough and bright and mostly forms good contrast with adjacent bedrock such that the flow is locally more distinct here than in the visible Landsat view. For further comparison, infrared Landsat images (right) again show image brightnesses related to mineral chemistry, but the lava flows appear lighter than in the visible wavelengths. Consequently, the lower lava flow becomes fairly obscure among the various surrounding rocks, just as the upper flow did in the radar image. The

    A generic, U.S.-based analysis approach was evaluated with respect to corn and soybean identification in Argentina. Using crop separability expectations derived from the analysis of Argentina ancillary data and U.S. spectral data, the approach was applied to Argentina spectral data by an expert analyst. Eight classes were detected and labeled independent of ground data. A high correspondence between the labels and limited ground data was achieved. It was concluded that an approach of this type could be applied to Argentina without major difficulty.

  14. Insights into Pleistocene palaeoenvironments and biostratigraphy in southern Buenos Aires province (Argentina) from continental deposits

    The coastal cliffs of the Buenos Aires province (Argentina) have been the subject of intense paleontological studies since the XIX century. Therefore, many of the type localities in which is based the late Cenozoic Pampean biostratigraphic/chronostratigraphic scheme are located in this area. In this context, the sedimentites that crop out near the mouth of the Chocorí Creek contain a set of palaeontological sites that, because of their richness and well-preserved fossil content, hold high national and international importance. The aims of the present contribution are: 1) to make a stratigraphic and sedimentological characterization of the study area; 2) to list the fauna outcropped at these palaeontological sites and establish a biostratigraphic framework; 3) to elaborate a palaeoenvironmental model for the area. The study interval was informally subdivided into a lower, middle and upper interval. Interpretation was based on the presence of a number of key features such as architectural elements; channel:overbank ratio and palaeosol occurrence. The first two intervals were interpreted as continental deposits of a fluvio-alluvial nature and are the focus of this paper. The upper interval was related to foreshore marine deposits and will be studied in a future contribution. The lower interval is characterized mainly by overbank architectural elements in which calcisols and argillic protosols were identified. Channel-fill deposits are isolated and surrounded by fine-grained overbank successions and sedimentary structures are suggestive of mixed-load transport. The contact between the lower and middle intervals is an irregular, highly erosive surface characterized by a significant vertical change in the facies. This surface defines the base of multistorey sandbodies which's internal arrangement alongside with the low participation of overbank deposits suggests deposition by a braided fluvial system. Palaeosols and vertebrate fossils were used as palaeoclimatic

    In the present work, 19 Mycobacterium bovis isolates from different cats were typified by spoligotyping. We detected nine spoligotypes. There was only one cluster, which grouped 11 of the isolates (57.9%), showing the main spoligotype from cattle from Argentina. The rest of the spoligotypes presented only one isolate each. Five of them were not found in cattle, and were unique and exclusive of cats. The isolates studied show that tuberculosis of bovine origin in cats constitutes a potential public health problem in Buenos Aires region. The identification of genotypes from non-natural hosts could contribute to understand the spread of bovine tuberculosis. This is the first report showing genetic profiles of M. bovis isolates in felines from Argentina.

    To describe the history, current situation, and future challenges of Argentinian neuropsychology. A brief historical description highlighting the most representative authors and publications is made. In addition, a survey was administered to a sample of 135 neuropsychologists practicing neuropsychology in Argentina. The survey explored the current neuropsychological practices among the respondents. Results show that most Argentinian neuropsychologists are: psychologists, women, and work in the clinical field in the country's major cities. Besides, the practice of neuropsychology is mostly unregulated with few training opportunities. Argentinian neuropsychology emerged from neurology in the early twentieth century and slowly progressed until the 1960s when the first organized research groups were created. Since then, a substantial and steady progress followed. However, more training opportunities and a better regulation of the discipline are needed. No similar studies have been conducted in the past, thus becoming one of the first to describe the development of neuropsychology in Argentina.

    A total of 143 Mycobacterium bovis isolates of pigs, from the most productive swine area in Argentina, were typed by spoligotyping. Twenty-two different spoligotypes were identified, and 133 (93%) isolates were grouped into 12 clusters. One of them, designed SB0140, was the most frequent because it held 83 (58%) isolates. This spoligotype also grouped 362 (43%) out of 841 isolates from previously typed cattle and, thus, constitutes the most frequent in our country. In addition, 135 (94%) isolates revealed spoligotypes identical to those of cattle, showing an epidemiological link. On the other hand, there were seven novel spoligotypes, six of which were also unique since they had only one isolate each. This study aimed to identify the spoligotypes of M. bovis isolated from pigs to contribute to a better understanding of the distribution of bovine tuberculosis in the main productive area of Argentina.

    Nine new Trechisibus species from South America (Peru and Patagonian Argentina) were recently described (Allegro & Giachino 2016). Five of them were based on material labelled "Argentina, Neuquen, Pen. Quetrihué" offered to the authors for study by its collector (Riccardo Sciaky). Shortly after publication, Martin Donabauer kindly communicated that a mistake probably had occurred, as they are five well known European Trechus species from Koralpe (Austria) living in low subalpine forests at 1200-1700 m a.s.l. As a subsequent control allowed us to ascertain that the collector had stayed in Koralpe collecting some material, a mistake evidently occurred in labelling, misleading a correct taxonomic interpretation of these species by the authors.

    The marine environments of Argentina have a remarkable extension, as well as high biological productivity and biodiversity of both macro- and microorganisms. Despite having a great potential for biotechnological applications, the microorganisms inhabiting these ecosystems remain mostly unexplored and unexploited. In this review, we study the research topics and the interactions among Argentinean laboratories, by analyzing current articles published on biotechnology-related marine microbiology by researchers of this country. In addition, we identify the challenges and opportunities for Argentina to take advantage of the genetic potential of its marine microorganisms. Finally, we suggest possible actions that could improve the development of this research field, as well as the utilization of this knowledge to solve societal needs.

    We initiated a study to elucidate the ecology and epidemiology of hantavirus infections in northern Argentina. The northwestern hantavirus pulmonary syndrome (HPS)-endemic area of Argentina comprises Salta and Jujuy Provinces. Between 1997 and 2000, 30 HPS cases were diagnosed in Jujuy Province (population 512,329). Most patients had a mild clinical course, and the death rate (13.3%) was low. We performed a serologic and epidemiologic survey in residents of the area, in conjunction with a serologic study in rodents. The prevalence of hantavirus antibodies in the general human population was 6.5%, one of the highest reported in the literature. No evidence of interhuman transmission was found, and the high prevalence of hantavirus antibody seemed to be associated with the high infestation of rodents detected in domestic and peridomestic habitats.

    In Argentina, studies on Varroa destructor resistance to coumaphos are still unknown. At present, high infestation levels of V. destructor are being detected in colonies of Apis mellifera after treatment with this acaricide. The aim of the present study was to determine the LC50 of coumaphos in V. destructor from four apiaries with high mite density after treatment with coumaphos. The LC50's were 112, 319, 127 and 133 microg/Petri dish for mites from the four apiaries. Significant LC50 differences were detected between resistant and susceptible mites. LC50 increased 197-559-fold when compared to the corresponding baseline, suggesting the development of resistance. These results are the first report of resistance to coumaphos in V. destructor in Argentina.

    2005-01-01

    Congenital transmission of Trypanosoma cruzi infection in Argentina has being increasing its relative importance with control of vectorial and transfusional transmission growth. It is for this reason that vertical transmission is seen, in the future, as a continuous source of infected newborns, even with vectorial and transfusional transmission completely controlled. Preventing vertical transmission of T.cruzi is not possible, but it can be precociously detected, permitting mother and child to be incorporated into the medical attention system, and so allowing the newbornś treatment with practically 100% efficacy. It is estimated that between 800 and 1700 children infected with T. cruzi by congenital transmission are born in Argentina, per year. The implementation of an early strategy of detection for an effective and opportune treatment acquires great relevance as a Public Health measure.

    In the central area of Argentina, the epidemiological and molecular characteristics of Chlamydophila pneumoniae infections in reptiles are still unknown. A nested polymerase chain reaction of the rpoB gene was used to detect C. pneumoniae in cloacal swab samples from 19 reptiles at a recreational area. Eleven (57.89%) reptiles were positive; the sequencing and phylogenetic analysis confirmed the presence of this bacterium. Neither C. pneumoniae DNA in the caregivers pharynges nor IgM antibodies anti-C. pneumoniae in their serum samples were detected; however, caregivers presented very high titers of IgG anti-C. pneumoniae. The detection of C. pneumoniae DNA in reptiles demonstrated the circulation of this agent in the recreational area and could be responsible for the exacerbated immune response of the personnel handling the reptiles, which suggests a potential zoonotic cycle. This is the first report of the detection of C. pneumoniae in reptiles in Argentina.

    The Argentina National Commission on Space Activities (CONAE) has been forecasting the UV Index for solar risk prevention from November 1996 up to the present. It is based on a parametric atmospheric radiative transfer calculation, including mainly the ozone attenuation from TOMS/NASA data and the altitude (pressure) and coordinates of the selected site. Daily predictions, for various locations of Argentina as well as for other countries are published via the web at www.conae.gov.ar. We present in this work the improved version of the CONAE UV Index using the TUV program developed by Madronich (www.acd.ucar.edu), with the inclusion of effective aerosol data estimated for each site. The forecast is also extended from one to several days in advance and a correction factor for cloudy sky is included.

    "From the second half of the 19th century, Argentina was, along with the United States and Brazil, one of the main destinations that attracted European emigration to America.... The arrival of more that six million people between 1869 and 1930 resulted in radical changes in the socioeconomic structure of the country. After the crisis of the 1930s the impact of a development plan based on the export of agricultural products waned and the economic growth accompanied with political instability generated a slowing decline of migratory flows, despite a new wave between 1945 and 1952. The decrease of international migration comes along with an important change in the composition by places of origin.... The article analyses the successive migratory policies of Argentina's government as well as the migrants' spatial distribution and their incorporation in the labor market."

    Avian influenza (AI) is an exotic disease in Argentina. A surveillance program for AI was conducted in backyard poultry during 1998-2005 in two regions: 1) region A, which included the avian population in the provinces that border Brazil, Bolivia, and Paraguay, and 2) region B, which included the rest of the provinces of the country. More than 8000 serum samples were tested for antibodies by enzyme-linked immunosorbent assay and/or agar gel immunodiffusion tests, and more than 18,000 tracheal and cloacal swabs were tested for virus by isolation in embryonated specific-pathogen-free eggs. This study was part of the AI prevention program in Argentina, which includes other avian populations such as commercial poultry and all the controls for importation and exportation of live birds. The results from backyard poultry were negative for AI.

    Phytolith reference collections are a prerequisite for accurate interpretation of soil phytolith assemblages aimed at reconstructing past vegetation. In this study a phytolith reference collection has been developed for several grasses native to central Argentina: Poa ligularis, Piptochaetium napostaense, Stipa clarazii, Stipa tenuis, Stipa tenuissima, Stipa eriostachya, Stipa ambigua, Stipa brachychaeta, Pappophorum subbulbosum, Digitaria californica, Bothriochloa edwardsiana and Aristida subulata. For each species, phytoliths present in the leaf blades were classified into 47 morphotypes, and their relative frequency determined by observing 300-400 phytoliths per sample (n = 5). Data were analyzed by complete linkage cluster analysis, using the Morisita Index as measure of association. The results showed differentiation among phytolith assemblages at species level or at plant functional type level. Cluster analysis separated C3 from C4 species and palatable from non-palatable species. This study highlights the possibility of reconstructing past vegetation in central Argentina grasslands through the analysis of soil phytolith assemblages.

    This article analyses, from a human rights' approach, a group of social programmes implemented in Argentina from the year 2002, at the time of the biggest socioeconomic crisis that the country has suffered in the last decades. The main characteristics of the programmes are reviewed, and their anti-poverty strategy, along with design and implementation, are evaluated in relation to human rights. An assessment is also made of the existence of mechanisms for citizens to present claims. Finally, a set of recommendations are made to facilitate the adaptation of the programmes analysed to the duties the State of Argentina has as result of its adherence to international laws on human rights. The analytical methodology proposed by this article could be applied to other policy areas.

    Bunyamwera virus (BUNV) (Bunyaviridae, genus Orthobunyavirus, serogroup Bunyamwera) is considered an emerging pathogen for humans and animals in American countries. The CbaAr-426 strain of BUNV was recovered from mosquitoes Ochlerotatus albifasciatus (Diptera: Culicidae) collected in Córdoba province (Argentina), where serological studies detected high seroprevalences in humans and animals. Molecular detection of Orthobunyavirus was performed in mosquitoes collected in Córdoba province. Seventeen mosquito pools of Oc. albifasciatus, Ochlerotatus scapularis and Culex quinquefasciatus (Diptera: Culicidae) showed positive results; four of these positive pools, all of Oc. scapularis, were sequenced. All amplicons grouped with BUNV in the Bunyamwera serogroup. The findings highlight the circulation of BUNV in Córdoba province and represent the first report of BUNV-infected Oc. scapularis mosquitoes in Argentina.

    Breast cancer is the most common type of cancer in females in Argentina, with an incidence rate similar to that in the USA. However, the contribution of the BRCA1 or BRCA2 mutation in breast cancer incidence has not yet been investigated in Argentina. In order to evaluate which BRCA1 polymorphisms or mutations characterize female breast cancer in Argentina, the current study enrolled 206 females with breast cancer from several hospitals from the southeast of Argentina. A buccal smear sample was obtained in duplicate from each patient and the DNA samples were processed for polymorphism analysis using the single-strand conformational polymorphism technique. The polymorphisms in BRCA1 were investigated using a combination of 15 primers to analyze exons 2, 3, 5, 20 and 11 (including the 11.1 to 11.12 regions). The BRCA1 mutations were confirmed by direct sequencing. Samples were successfully examined from 154 females and, among these, 16 mutations were identified in the BRCA1 gene representing 13.9% of the samples analyzed. One patient was identified with a polymorphism in exon 2 (0.86%), four in exon 20 (3.48%), four in exon 11.3 (3.48%), one in exon 11.7 (0.86%), two in exon 11.8 (1.74%), one in exon 11.10 (0.86%) and one in exon 11.11 (0.86%). The most prevalent alteration in BRCA1 was located in exon 11 (11 out of 16 patients; 68.75%). The objective of our next study is to evaluate the prevalence of mutations in the BRCA2 gene and analyze the BRCA1 gene in the healthy relatives of BRCA1 mutation carriers.

    Familial hypercholesterolemia (FH) is a genetic disorder characterized by elevated low-density lipoprotein cholesterol and early cardiovascular disease. As cardiovascular disease is a leading cause of mortality in Argentina, early identification of patients with FH is of great public health importance. The aim of our study was to identify families with FH and to approximate to the characterization of the genetic spectrum mutations of FH in Argentina. Thirty-three not related index cases were selected with clinical diagnosis of FH. Genetic analysis was performed by sequencing, multiplex ligation-dependent probe amplification, and bioinformatics tools. Twenty genetic variants were identified among 24 cases (73%), 95% on the low-density lipoprotein receptor gene. The only variant on APOB was the R3527Q. Four were novel variants: c.-135C>A, c.170A>C p.(Asp57Ala), c.684G>C p.(Glu228Asp), and c.1895A>T p.(Asn632Ile); the bioinformatics' analysis revealed clear destabilizing effects for 2 of them. The exon 14 presented the highest number of variants (32%). Four variants were observed in more than 1 case and the c.2043C>A p.(Cys681*) was carried by 18% of index cases. Two true homozygotes, 3 compound heterozygotes, and 1 double heterozygote were identified. This study characterizes for the first time in Argentina genetic variants associated with FH and suggest that the allelic heterogeneity of the FH in the country could have 1 relative common low-density lipoprotein receptor mutation. This knowledge is important for the genotype-phenotype correlation and for optimizing both cholesterol-lowering therapies and mutational analysis protocols. In addition, these data contribute to the understanding of the molecular basis of FH in Argentina. Copyright © 2017 National Lipid Association. Published by Elsevier Inc. All rights reserved.

    In Argentina, years of rampant inflation and bottlenecked economic progress have given way to a period of giant financial influx -- through privatization. Privatization of the national oil company is seen as a culmination of the process. As petroleum accounts from some 8% of Gross Domestic Product, and represents a crucial support for sustained economic development in general, the liberation of the oil sector to free market competition is ascensive and assertive.

    The energy levels, oscillator strengths, line strengths, and transition probabilities for transitions among the terms belonging to the 3s{sup 2}3p{sup 2}, 3s3p{sup 3}, 3s{sup 2}3p3d, 3s{sup 2}3p4s, 3s{sup 2}3p4p and 3s{sup 2}3p4d configurations of silicon-like ions (Zn XVII, Ga XVIII, Ge XIX, and As XX) have been calculated using the configuration-interaction code CIV3. The calculations have been carried out in the intermediate coupling scheme using the Breit–Pauli Hamiltonian. The present calculations have been compared with the available experimental data and other theoretical calculations. Most of our calculations of energy levels and oscillator strengths (in length form) show good agreement with both experimental and theoretical data. Lifetimes of the excited levels have also been calculated. -- Highlights: •We have calculated the fine-structure energy levels of Si-like Zn, Ga, Ge and As. •The calculations are performed using the configuration interaction method (CIV3). •We have calculated the oscillator strengths, line strengths and transition rates. •The wavelengths of the transitions are listed in this article. •We also have made comparisons between our data and other calculations.

    In 1992, the definition of erectile dysfunction (ED) replaced the old term of impotence that had been used for many centuries, in order to avoid the general confusion existing until today in this field. In the past, the origin of impotence had been attributed to different causes such as psychological diseases, or witches and demons. In 1764, Fusanacci described impotence that can occur in the male as well as in the female, as a defect in reproduc-tion. The main causes responsible for impotence were identified as inability to achieve erection, a very fluid seminal ejaculation, a defective organ, dryness of testicles, and lack of copulative power after many sexual intercourses with healthy women. Some decades later in 1847, Beatty affirmed that one of the most remarkable changes that can be observed in the passage from childhood to maturity is the development of the sexual organs, followed by the appearance of new sensations. He distinguished impotence that occurs only in men from sterility that for him affects women, and divided the causes of impotence into 3 classes: organic, functional and moral (today defined as psychological). For Beatty, the progress of knowledge had taken away magic and sorcery from the human mind and now it was widespread only among the lowest and most ignorant classes of humble people. In this way, he shows the evolution of medical science in XIX century in accepting only the rational explanation of the human diseases.

  9. X-ray fluorescence spectrometry on paper characterization: A case study on XVIII and XIX century documents

    Paper documents from XVIII and XIX centuries were analyzed by energy dispersive X-ray fluorescence. The presence of Co (400 µg g - 1 ), Ni (300 µg g - 1 ), As (2000 µg g - 1 ) and Bi (200 µg g - 1 ) in Dutch papers and a Hespe watermarked paper allowed distinguishing them from the rest of the papers. The elemental composition of the ink present in these documents was also studied with the same technique and it was concluded that these elements could not be originated from ink dissemination. Strong positive Spearman correlations between Co, Ni, As and Bi were found in all Dutch and Hespe watermarked papers. Potassium and Ca are the predominant elements in all analyzed papers. Their concentration levels also allowed differentiating between Dutch and Hespe papers and the rest of the papers. Other elements such as Ti, Fe, Cu, Zn, Ba and Pb were also found. In this work a bibliographic research about the possible origin of each one of the mentioned elements present in the papers is also reported.

    In the article there is considered the history of the development ofsanitary and hygienic standards in school institutions of Tobolsk province in the late XIX century. In comparative terms there is characterized the presented in that period the legal framework regulating of abidance by hygienic and sanitary standards in educational institutions. There was executed an careful analysis of hygienic conditions on the example of the Tobolsk male gymnasium with a comparison of similar conditions in another Siberian educational/childcare institution--the Yenisei female progymnasium. The main sources in the study were reports of educators: I. Gursky--about hygienic living conditions of the inmates of the Tobolsk gymnasium and P.M. Golovachev--about sanitary conditions in the Yenisei female gymnasium. Contemporaries paid a great attention to such health and safety standards as heating, ventilation, lighting, capacity of classrooms and boarding facilities, the violation of which led to a deterioration in the health of students and the growth of the epidemics in mention educational institutions.

    The family Cavognathidae (Coleoptera: Cucujoidea) in Argentina is represented by three species of the genus Taphropiestes Reitter, 1875: T. fusca Reitter, 1875 [Chubut], T. magna Ślipiński & Tomaszewska, 2010 [Río Negro; Chubut], and T. plaumanni Ślipiński & Tomaszewska 2010 [Buenos Aires]. A total of 2565 larvae (multiple instars), 83 pupae, 2028 live adults, and 16 dead adults of T. plaumanni were found in Argentina between 2005 and 2013 in the nests of birds representing the families Columbidae, Emberizidae, Falconidae, Furnariidae, Hirundinidae, Mimidae, Passeridae, Psittacidae, Troglodytidae and Tyrannidae. The adults were most abundant in closed mud nests of Furnarius rufus (Gmelin, 1788) [Furnariidae] and its inquiline birds, but the larvae were most abundant in wood nest boxes. When T. plaumanni was scarcely represented in bird nests from some localities, Alphitobius diaperinus (Panzer, 1797), an exotic darkling beetle [Col.: Tenebrionidae: Tenebrioninae], and one native species, Phobelius crenatus Blanchard, 1842 [Col.: Tenebrionidae: Lagriinae], were most abundant in stick nests of Furnariidae. In contrast, when A. diaperinus and P. crenatus were absent in one locality from the province of Buenos Aires, T. plaumanni was the most abundant beetle. A complete account of data is provided for these collections of T. plaumanni in Argentina. Known distributional data for all Argentinian species of Taphropiestes are plotted on maps with biogeographical provinces indicated.

    A representative of the U.S. Geological Survey traveled to Buenos Aires, Argentina, in November 1986, to discuss water information systems and data bank implementation in the Argentine Government Center for Water Resources Information. Software has been written by Center personnel for a minicomputer to be used to manage inventory (index) data and water quality data. Additional hardware and software have been ordered to upgrade the existing computer. Four microcomputers, statistical and data base management software, and network hardware and software for linking the computers have also been ordered. The Center plans to develop a nationwide distributed data base for Argentina that will include the major regional offices as nodes. Needs for continued development of the water resources information system for Argentina were reviewed. Identified needs include: (1) conducting a requirements analysis to define the content of the data base and insure that all user requirements are met, (2) preparing a plan for the development, implementation, and operation of the data base, and (3) developing a conceptual design to inform all development personnel and users of the basic functionality planned for the system. A quality assurance and configuration management program to provide oversight to the development process was also discussed. (USGS)

    The biochemical and serological properties of Haemophilus paragallinarum isolates recovered from 11 recent outbreaks of infectious coryza in layer hens and one case of swollen-head syndrome in broilers in Argentina are described. Twenty-four isolates had the typical biochemical properties of H. paragallinarum. All isolates were serotyped according to the Page scheme. Ten of the isolates were serovar A, 11 were serovar B, one was serovar C, and two isolates could not be serotyped. The isolates were also examined using a panel of monoclonal antibodies (MAbs) for Page serovars A (one MAb available) and C (three MAbs available). The serovar B isolates all failed to react with any MAb. The serovar C isolate reacted with all three serovar C MAbs but not with the serovar A MAb. Only six of the 10 serovar A isolates reacted with the serovar A MAb. These results indicate that H. paragallinarum isolates from Argentina are antigenically distinct from those examined in other countries, and it is suggested that coryza vaccines intended for use in Argentina may be more effective if based on local strains.

    Brucellosis is a zoonotic disease transmitted from an animal reservoir to humans. Both, wildlife and domestic animals, contribute to the spreading of these zoonosis. The surveillance of the animal health status is strictly regulated for domestic animals, whereas disease monitoring in wildlife does not exist. The aim of the present study was to provide data on the prevalence of anti-Brucella antibodies in Chaetophractus villosus from a region of La Pampa, Argentina to assess public health risks. The C. villosus is endemic to South America, and in Argentina it represents a food resource for human consumption. A total of 150 sera of armadillos bleeding between 2007 and 2010 were tested using buffered plate antigen test (BPAT), serum agglutination test (SAT), 2-mercaptoethanol (2-ME) and complement fixation test (CFT), for the detection of anti-Brucella antibodies. Antibodies to Brucella sp. were found in 16% (24:150) of the armadillos tested using the BPAT test. All 24 positive samples were confirmed by the SAT, 2-ME and CFT tests. Strain isolation was attempted from liver and spleen samples of two animals with positive serology. Isolates were characterized by conventional biotyping and identification of specific DNA using polymerase chain reaction (PCR). A total of 2 isolates were recovered from spleen and liver. Both of them were identified as Brucella suis biovar 1. This preliminary study provides the first report on the seroprevalence of brucellosis and describes the first isolate of B. suis biovar 1 in C. villosus in Argentina.

    In 1955, the area infested by Aedes aegypti in Argentina was estimated as 1,500,000 km2; and in 1963, the species was considered to be eradicated from Argentina. In 1995, the Argentine Ministry of Health reported reinfestation by Ae. aegypti. During 1994-95, the Ministry of Health of Córdoba Province, Zoonosis Department, established a surveillance system for Ae. aegypti in Córdoba Province, Argentina. This report is a summary of results obtained thus far. In total, 74 localities in Córdoba Province were sampled during August 1994-April 1996, resulting in 5 positives (6.7%): Villa María city, Villa Nueva, and Córdoba city in 1995, and Juarez Celman and Jesús María in 1996. In Villa María and Villa Nueva, Ae. aegypti was present until June 1995 (autumn) and reappeared in December 1995. In Córdoba city, Ae. aegypti was eliminated from the only positive house in May 1995, but it reappeared in March 1996. Reappearance of Ae. aegypti in this temperate area in early summer may have been due to the survival of individuals during winter and not to reintroduction during summertime. The last previous active surveillance for Ae. aegypti in Córdoba Province was carried out more than 30 years ago.

    This study examined whether healthier family dynamics were associated with higher personal strengths of resilience, sense of coherence, and optimism among dementia caregivers in Argentina. Caregivers are usually required to assist individuals with dementia, and family members have typically fulfilled that role. Personal strengths such as resilience, sense of coherence, and optimism have been shown to protect caregivers from some of the negative experiences of providing care, though the family-related variables associated with these personal strengths are largely unknown. Hierarchical multiple regressions investigated the extent to which family dynamics variables are associated with each of the caregiver personal strengths after controlling for demographic and caregiver characteristics. A sample of 105 caregivers from Argentina completed a set of questionnaires during a neurologist visit. Family dynamics explained 32% of the variance in resilience and 39% of the variance in sense of coherence. Greater family empathy and decreased family problems were uniquely associated with higher resilience. Greater communication and decreased family problems were uniquely associated with higher sense of coherence. Optimism was not found to be significantly associated with family dynamics. These results suggest that caregiver intervention research focused on the family may help improve caregiver personal strengths in Argentina and other Latin American countries. PMID:27413574

    AIM: To estimate the progression of the hepatitis C virus (HCV) epidemic and measure the burden of HCV-related morbidity and mortality. METHODS: Age- and gender-defined cohorts were used to follow the viremic population in Argentina and estimate HCV incidence, prevalence, hepatic complications, and mortality. The relative impact of two scenarios on HCV-related outcomes was assessed: (1) increased sustained virologic response (SVR); and (2) increased SVR and treatment. RESULTS: Under scenario 1, SVR raised to 85%-95% in 2016. Compared to the base case scenario, there was a 0.3% reduction in prevalent cases and liver-related deaths by 2030. Given low treatment rates, cases of hepatocellular carcinoma and decompensated cirrhosis decreased < 1%, in contrast to the base case in 2030. Under scenario 2, the same increases in SVR were modeled, with gradual increases in the annual diagnosed and treated populations. This scenario decreased prevalent infections 45%, liver-related deaths 55%, liver cancer cases 60%, and decompensated cirrhosis 55%, as compared to the base case by 2030. CONCLUSION: In Argentina, cases of end stage liver disease and liver-related deaths due to HCV are still growing, while its prevalence is decreasing. Increasing in SVR rates is not enough, and increasing in the number of patients diagnosed and candidates for treatment is needed to reduce the HCV disease burden. Based on this scenario, strategies to increase diagnosis and treatment uptake must be developed to reduce HCV burden in Argentina. PMID:27239258

    Natural infection with Trichinella has been described in more than 150 mammalian species. However, few reports of Trichinella infection in wild animals have come from Argentina. In this study, muscle tissue was obtained from wild animals in Argentina with the aim of evaluating the presence of Trichinella. A total of 169 muscle samples were collected to determine the presence of Trichinella larvae by artificial digestion. The 169 muscle samples originated from 12 species including 36 opossums (Didelphis albiventris), 19 armadillos (Chaetophractus villosus), 9 capybaras (Hydrocaeris hydrocaeris), 1 puma (Puma concolor), 3 grey fox (Lycalopex gymnocercus), 6 coypus (Myocastor coypus), 6 skunks (Conepatus chinga), 2 ferrets (Galictis cuja), 66 rats (Rattus norvegicus), 6 mice (Mus musculus), 12 wild boars (Sus scrofa), and 3 wild cats (Felis geoffroyi). Trichinella infection was detected in 1 puma [2 larvae per gram (LPG)], 3 wild boars (8-420 LPG), 3 armadillos (0.04-0.08 LPG), and 9 rats (0.1 to 150 LPG). Only 3 Trichinella isolates, of 1 rat and 2 wild boars from Neuquén, were identified as Trichinella spiralis by nested PCR. The presence of Trichinella infection among wild animal populations suggests a sylvatic cycle of transmission in Argentina, which can serve as a reservoir for humans and domestic animals. Further, evidence of high prevalence in rats emphasizes the need to improve pig management, mainly in small individual farms without adequate technology, to enhance the quality of feeds, and to improve veterinary services to avoid exposure of pigs to Trichinella.

    The objective of the present study was to perform a systematic review and a meta-analysis in order to determine the epidemiological profile of multiple sclerosis (MS) in Argentina. A systematic search was performed in electronic databases and lists of references, focused on epidemiological studies of MS in Argentina. Data obtained were analyzed with the StatsDirect software. A total of 275 studies were retrieved of which 15 included. The prevalence was described in 4 studies, most of them reported a prevalence of 17 cases per 100,000 inhabitants. The incidence, prospectively described in one hospital based study, was 1.76 cases per 100,000 persons-years. In this study, 65.5% of cases were relapsing-remitting MS, 21.5% secondary progressive, 10.6% primary progressive and 2.4 progressive with relapsing MS. Female/male ratio was 1.55. This study provided information regarding the epidemiological feature of MS in Argentina. Future researches will contribute to increase the number of recorded cases, and the knowledge on the behavior of this disease in the country.

    There is currently a deficiency of physicians in pediatric intensive care units (PICU). The cause of this deficit is multifactorial, although the burnout phenomenon has been described as relevant. To analyze the situation of human resource in the pediatric intensive care units in Argentina and measure the level of burnout. An observational cross-sectional study through surveys administered electronically; the Maslach Burnout Inventory was used. Physicians that work at public o private pediatric intensive care units in Argentina during at least 24 hours per week were invited to participate. A total of 162 surveys were completed (response rate 60%). We observed a high risk of burnout in emotional exhaustion in 40 therapists (25%), in fulfillment in 9 (6%), and depersonalization in 31 (19%). In combination, 66 professionals (41%) had a high risk of burnout to some extent; there were independent protective factors of this risk as to be certified in the specialty (ORA 0.38, 95% CI 0.19 to 0.75) and work in public sector PICU (ORA 0.31, 95% CI 0.15 to 0.65), while working more than 36 hours/week on duty increased the risk (ORA 1.94, 95% CI 1.1 to 3.85). Additionally, 31% said that they did not plan to continue working in intensive care, and 86% did not think to continue with on call duties in the following years. Over 60% of respondents reported that changes in professional practice (salary, staff positions, early retirement, fewer loads on call) could prolong the expectation of continuing activities in PICU. A significant percentage of doctors working in the PICU of Argentina have a high risk of burnout syndrome and a low expectation of continuing in the field.

  16. Variability study of entomopathogenic nematode populations (Heterorhabditidae) from Argentina.

    Entomopathogenic nematodes (EPN) belonging to the Heterorhabditidae family are lethal parasites of soil-dwelling insects. Two species were reported in Argentina: Heterorhabditis argentinensis and Heterorhabditis bacteriophora characterized mainly by morphometric features. In this work a comparative and phylogenetic study between five Heterorhabditis populations from Argentina was conducted to analyze the variability between strains and to evaluate the taxonomic position of Heterorhabditis argentinensis. The PCA analyses of morphometric characters separated the larger juvenile, female and male H. argentinensis from H. bacteriophora populations. The juvenile (IJs) stage provided the clearest separation of Heterorhabditis populations presenting the least variability between strains. The variable L and MBW were highly related to H. argentinensis IJs. Three groups were separated by this stage considering PC1 and PC2: one formed by H. bacteriophora OLI, RIV and RN strains, (isolates from Córdoba and Río Negro province), one for H. bacteriophora VELI strain (Buenos Aires province) and one for H. argentinensis (Santa Fe province). Heterorhabditis bacteriophora VELI and H. argentinensis isolated from regions with more rainfalls and humidity presented larger values for morphometric features. Molecular analyses showed the Argentinian populations (H. bacteriophora VELI strain and H. argentinensis), forming a same clade, with six other H. bacteriophora populations (not from Argentina) with a genetic similarity between them of 99%. Heterorhabditis argentinensis presented one unique nucleotide that was not present in any of the other species of the clade. Considering the results of this study H. argentinensis would be conspecific to H. bacteriophora, constituting a strain with a great morphometric variation where the host and climatic conditions could have influenced on the measurements.

    To describe the process of approval and implementation of a comprehensive smoke-free law in the province of Santa Fe, Argentina, between 2005 and 2009. Review of the Santa Fe smoke-free legislation, articles published in local newspapers and documentation on two lawsuits filed against the law, and interviews with key individuals in Santa Fe. Efforts to implement smoke-free policies in Santa Fe began during the 1990s without success, and resumed in 2005 when the provincial Legislature approved the first 100% smoke-free subnational law in Argentina. There was no strong opposition during the discussions within the legislature. As in other parts of the world, pro-tobacco industry interests attempted to block the implementation of the law using well known strategies. These efforts included a controversy media campaign set up, the creation of a hospitality industry association and a virtual smokers' rights group, the introduction of a counterproposal seeking modification of the law, the challenge of the law in the Supreme Court, and the proposal of a weak national bill that would 'conflict' with the subnational law. Tobacco control advocates sought media attention as a strategy to protect the law. Santa Fe is the first subnational jurisdiction in Latin America to have enacted a comprehensive smoke-free policy following the recommendations of the World Health Organization (WHO) Framework Convention on Tobacco Control. After 3 years of implementation, pro-tobacco industry forces failed to undermine the law. Other subnational jurisdictions in Argentina, as well as in Mexico and Brazil are following the Santa Fe example.

    The population of Argentina is the result of the intermixing between several groups, including Indigenous American, European and African populations. Despite the commonly held idea that the population of Argentina is of mostly European origin, multiple studies have shown that this process of admixture had an impact in the entire Argentine population. In the present study we characterized the distribution of Indigenous American, European and African ancestry among individuals from different regions of Argentina and evaluated the level of discrepancy between self-reported grandparental origin and genetic ancestry estimates. A set of 99 autosomal ancestry informative markers (AIMs) was genotyped in a sample of 441 Argentine individuals to estimate genetic ancestry. We used non-parametric tests to evaluate statistical significance. The average ancestry for the Argentine sample overall was 65% European (95%CI: 63–68%), 31% Indigenous American (28–33%) and 4% African (3–4%). We observed statistically significant differences in European ancestry across Argentine regions [Buenos Aires province (BA) 76%, 95%CI: 73–79%; Northeast (NEA) 54%, 95%CI: 49–58%; Northwest (NWA) 33%, 95%CI: 21–41%; South 54%, 95%CI: 49–59%; p<0.0001] as well as between the capital and immediate suburbs of Buenos Aires city compared to more distant suburbs [80% (95%CI: 75–86%) versus 68% (95%CI: 58–77%), p = 0.01]. European ancestry among individuals that declared all grandparents born in Europe was 91% (95%CI: 88–94%) compared to 54% (95%CI: 51–57%) among those with no European grandparents (p<0.001). Our results demonstrate the range of variation in genetic ancestry among Argentine individuals from different regions in the country, highlighting the importance of taking this variation into account in genetic association and admixture mapping studies in this population.

    Hepatitis A, a vaccine preventable disease, is now of transitional or intermediate endemicity in Argentina, as the epidemiologic pattern of the disease has shifted with improvements in living conditions in some parts of the country. Increase in the susceptibility of older children and adults has led to increasing disease incidence. Molecular epidemiology has played an important role in the understanding of HAV infection by identifying modes of spreading and by permitting the monitoring of changes in circulating virus brought about by prevention programs. South American isolates characterized are limited. Eighty-two sporadic and outbreak isolates from Argentina were sequenced in the VP1/2A region of HAV genome over a 9-year period. All the isolates belonged to subgenotype IA. All our sequences grouped into two big clusters. Apparently, at least two lineages have been co-circulating in the same place at the same time. Despite great genetic variability, few point amino acid changes could be deduced. Four sequences showed an Arg --> Lys substitution at 1-297 which characterized the genotype IB at the amino acid level. Many isolates carried a conservative amino acid substitution Leu --> Ile at position 42 of the 2A domain, previously described as a possible fingerprint of HAV sequences in Brazil. The other rare changes have been found before, except for a 1-277 Asn --> Ser substitution displayed in two isolates that has not been previously reported. Argentina recently implemented universal vaccination in 1-year-old children. Molecular tools would be useful in an active surveillance program.

    The Intensive Care Unit Liaison Nurse (ICULN), also known as an outreach nurse, is an advanced practice nursing role that emerged in the late 1990s in Australia and the United Kingdom (UK). Little is known about this role in less developed economies. To describe the activities undertaken by ICULNs in Argentina. Prospective, descriptive, observational, single site study in an Argentinean metropolitan tertiary referral hospital. Adult patients under ICULN follow up were included in the sample. Data on ICULN activities and patients were collected using an established tool developed by The Australian Intensive Care Unit Liaison Nurse Forum. Descriptive statistics were used to summarise the findings. Two hundred patients were visited by the ICULNs during the study period. The mean age of patients was 52.5 years (SD 17.7). Cardiovascular disease (n=104, 52%), respiratory disease (n=90, 45%) and diabetes (n=40, 20%) were the most common comorbidities. 110 (55%) patients had surgical procedures. The primary reasons for ICULN visit were follow up post ICU discharge (n=138, 69%) and ward referral (n=46, 23%). 136 (68%) patients received up to 3 visits; the remaining 64 (32%) patients received ≥4 visits. In those patients in need of ≥4 visits ICULNs initiated more non-medical treatments (100%), referred to escalate treatment (35%) and to a higher level of care (13.8%) than in those who were visited up to 3 times. This study is the first to document ICULN activity in Argentina using an international framework and data set. These findings can assist with understanding an advanced practice nursing role in Argentina. It may facilitate future comparisons with other contexts and could help managers implementing the role in similar settings. Further investigation will help develop this practice and document its influence on patient outcomes. Copyright © 2016 Australian College of Critical Care Nurses Ltd. Published by Elsevier Ltd.

    Neonatal mortality (NM) refers to deaths occurring between birth and 27 days of life. This component of infant mortality has shown the least reduction over the past 50 years. The objective of this study was to analyze the course and characteristics of NM in Argentina. This was a descriptive, ecological study of NM in Argentina conducted between 2005 and 2014 to analyze its course, causes, and the relevance of prematurity and a low birth weight. Records of the Health Statistics and Information Department of the Ministry of Health of Argentina were used. The neonatal mortality rate reduced by 19.2% (2005: 8.9‰; 2014: 7.2‰); the early component (between birth and 6 days of life), by 20% (2005: 6.5‰; 2014: 5.2‰); and the late component (between 7 and 27 days of life), by 13% (2005: 2.3‰; 2014: 2‰). Disorders originating in the perinatal period and congenital malformations were the cause of more than 95% of neonatal deaths in this period. The relative significance of disorders originating in the perinatal period reduced, but that of congenital malformations increased. Preterm and low birth weight live births had the greatest risk of neonatal death. A younger gestational age and a lower birth weight resulted in a lower reduction of specific neonatal mortality rate. In the past 10 years, NM has reduced significantly. Disorders originating in the perinatal period and congenital malformations were the cause of almost all deaths in this age group. NM was associated with a low birth weight and prematurity.

    The first confirmed case of Rickettsia massiliae infection in the New World (Buenos Aires, Argentina) is described. To date, only two cases of human infection had been reported in Europe. The patient, a woman, had a fever, a palpable purpuric rash on the upper and lower extremities, and a skin lesion (eschar) on the right leg compatible with tache noire. When interviewed, she reported having had contact with dog ticks. After treatment with doxycycline for 12 days, her symptoms resolved. Rickettsia massiliae infection was diagnosed by molecular-based detection of the microorganism in a biopsy specimen of the eschar. PMID:20348520

    2015-05-01

    The growing popularity of cognitive-behavioral therapy (CBT) has helped reshape the mental health scene in the city of Buenos Aires, historically the stronghold of psychoanalysis. In the early 1980s, CBT was infrequently used and sometimes overtly resisted in the field of mental health. Almost 3 decades later, the impact of CBT has increased dramatically in Argentina, not only in independent practice but also in the health system and in everyday life. This article aims to describe the process by which Argentine psychotherapists first adopted this new theoretical framework.

    In this paper the historical-epistemological statute of nineteenth-century European positivism is discussed to further develop its scope in the constitution of Science in general and in the conformation of the disciplines tied to the human behavior in the time of the creation of the nation's institutions in Argentina. The ideological bias that this thinking legitimates in key moments of identity construction, such as the Centenary period, is analyzed. Finally, emphasis is made on the incidence of positivism in other countries in the region observing in every case the same ideological bias found in the Argentinean case, tinged by cultural and socio-political variables.

    VNTR loci provide a wealth of information for human genetic research, ranging from gene mapping to paternity testing and forensic identification. In this study we report the construction, validation, and analysis of the first local genetic database for VNTR markers for Argentina. A sample of the metropolitan population of Buenos Aires was typed by means of six VNTR systems. Allele frequencies and expected heterozygosity were calculated. The sample set was further tested for departures from Hardy-Weinberg equilibrium and power of exclusion. Allele frequency distributions are compatible with previously reported data on Caucasian populations, and no departures from Hardy-Weinberg equilibrium were detected.

We comment on the rules for maternity leave that have been passed recently for research scholars doing their PhDs and on the number of women scientists that occupy decision making-positions in science. We also present some evidence that seems to indicate that, among young scientists, women are more willing to occupy leadership positions and that the Argentinean society is more accepting of this new role.

    Soybean biomass for biodiesel, produced in Argentina amongst other places, is considered by some to reduce greenhouse gas emissions and mitigate climate change when compared with fossil fuel alternatives. To ensure that the production of biofuels is 'sustainable', EU institutions and national governments are designing certification schemes for the sustainable production of biomass. In this paper, we question the validity of these proposed environmental standards, using the production of Argentine soybean as a case study. We highlight the negative environmental and social impacts of intensive soybean production, and conclude that certification schemes are unlikely to be able to address the detrimental impacts of increased biofuel production and trade.

    A total of 111 samples (43 faeces and 79 gastrointestinal tracts) of 14 wild carnivore species from 12 Argentine provinces were analyzed. Helminth eggs were identified in 73% of the faecal samples and adult worms were recovered from 81% of the gastrointestinal tracts. We found 19 helminth species. Among the most frequent findings were parasites of domestic carnivores, namely Toxocara canis, Toxocara cati, Toxascaris leonina, Ancylostoma caninum, Ancylostoma tubaeforme and Uncinaria stenocephala. In addition, new hosts are reported for 6 nematode species and 5 helminth species are recorded for the first time in Argentina: Aonchotheca putorii, Molineus brachiurus, Cyathospirura chevreuxi, Physaloptera praeputialis and Oncicola martini.

    The aims of the Iron Project and the Rmax Project are detailed study of radiative and collisional processes of astrophysically abundant atoms and ions, mainly iron and iron-peak elements, over a wide energy range, from infra-red to X-rays. We will present the complete results on photoionization, partial and total, of fine structure levels with n <= 10 of Fe XVII. They correspond to a large-scale computation using a wave function expansion containing 60 levels of the core. Preliminary results on total recombination rate coefficients ranging over low to very high temperatures, especially where the ion is abundant in astrophysical plasmas, will be presented. We will also report the latest results on oscillator strengths for photo-excitations in Fe XIX. This highly charged nitrogen-like iron ion has over thousands of bound fine structure levels. The calculations have been carried out in relativistic Breit-Pauli R-matrix (BPRM) method. The forbidden electric quadrupole, electric octupole, magnetic dipole and magnetic quadrupole transitions for Fe XIX correspond to fine structure levels upto 4p obtained from atomic structure calculations in Breit-Pauli approximation.

    The present study was carried out to assess if there is an anticipation of age at onset in younger generations of familial multiple sclerosis (FMS) vs. sporadic MS (SMS) in Argentina. multicenter study that included patients from 14 MS Centers of Argentina. Patients were considered as FMS if they had in their family at least one relative of first or second degree diagnosed with MS; otherwise, patients were considered to have SMS. We compared the age at onset between familial and sporadic cases as well as the age at onset between relatives from different generations in FMS vs. SMS. 1333 patients were included, 97 of them were FMS (7.3%). A lower age at onset in the younger generations of FMS cases was found compared with older generations of FMS as well as. SMS cases (24.1±3.7 years vs. 30.3±5.7 years, and 32.4±9.4 respectively; p<0.001). No differences were observed between older generations of FMS vs. SMS cases (p=0.12). we observed an anticipation of age at onset of MS in younger generations of patients with FMS vs. older generations of FMS and SMS.

    The Argentinian population is mainly of Caucasian origin, with a small contingent of indigenous descent. The aim of this study is to test the hypothesis that a panel of mutations designed for European countries is not optimal as a first-line molecular diagnosis for routine use in this country of mixed European origin. Phenotype analyses combined with a European screening panel of 71 mutations followed by Sanger sequencing and large rearrangement study, were used to characterize the identification and distribution of CFTR mutations in the Santa Fe province of Argentina. Clinical review of 121 subjects suspected of CF during childhood led to selection of 83 unrelated patients. Thirty four different mutations, including two new ones, c.2554dupT and p.Leu49Pro, were detected. The total sensitivity was 91% (n = 151/166 alleles). Frequencies of CFTR mutations in Argentinian populations differ from those of their European ancestry. A new first line panel of 21 CFTR mutations with a sensitivity of 84% is proposed for routine use in central Argentina.

  14. Conservative litigation against sexual and reproductive health policies in Argentina.

    In Argentina, campaigns for the recognition of sexual and reproductive rights have sparked opposition through litigation in which the dynamics of legal action have come from self-proclaimed "pro-life" NGOs, particularly since 1998, when the conservative NGO Portal de Belén successfully achieved the banning of emergency contraception through the courts. The activities of these groups, acting as a "civil arm" of religion, are focused primarily on obstructing access to legally permissible abortions and bringing about the withdrawal of a number of recognized public policies on sexual and reproductive health, particularly the 2002 National Programme for Sexual Health and Responsible Procreation. This paper analyzes the litigation strategies of these conservative NGOs and how their use of the courts in Argentina has changed over the years. It gives examples of efforts in local courts to block individual young women from accessing legal abortion following rape, despite a ruling by the National Supreme Court of Justice in 2012 that no judicial permission is required. In spite of major advances, the renewed influence of the Catholic hierarchy in the Argentine political scene with the accession of the new Pope poses challenges to the work by feminists and women's movements to extend and consolidate sexual and reproductive rights.

  15. Conflicting duties over confidentiality in Argentina and Peru.

    The medical duty of confidentiality represents a key element for the provision of reproductive and sexual health services. In some Latin American countries, such as Argentina and Peru, the legal systems impose—or are interpreted as imposing—on health professionals the duty of confidentiality, but also the duty to report the commission of a public order offense that they know about owing to the practicing of their profession. In these countries, the conflicting duties and the criminalization of abortion cause severe public health and human rights problems when health professionals assist their patients for post-abortion treatment. Typically, patients are deterred from seeking prompt medical care, and their privacy, autonomy, and dignity are violated. A 2010 ruling from the Supreme Court of Argentina and a 2004 ruling from the Inter-American Court of Human Rights emerge as important instruments that grant a more adequate protection of medical confidentiality. © 2010 International Federation of Gynecology and Obstetrics.

    • Background and Aims Phytolith reference collections are a prerequisite for accurate interpretation of soil phytolith assemblages aimed at reconstructing past vegetation. In this study a phytolith reference collection has been developed for several grasses native to central Argentina: Poa ligularis, Piptochaetium napostaense, Stipa clarazii, Stipa tenuis, Stipa tenuissima, Stipa eriostachya, Stipa ambigua, Stipa brachychaeta, Pappophorum subbulbosum, Digitaria californica, Bothriochloa edwardsiana and Aristida subulata. • Methods For each species, phytoliths present in the leaf blades were classified into 47 morphotypes, and their relative frequency determined by observing 300–400 phytoliths per sample (n = 5). Data were analyzed by complete linkage cluster analysis, using the Morisita Index as measure of association. • Key Results The results showed differentiation among phytolith assemblages at species level or at plant functional type level. Cluster analysis separated C3 from C4 species and palatable from non-palatable species. • Conclusions This study highlights the possibility of reconstructing past vegetation in central Argentina grasslands through the analysis of soil phytolith assemblages.

    Dusky dolphin (Lagenorhynchus obscurus) acoustic sounds were characterized by analyzing narrowband recordings [0-16 kHz in New Zealand (NZ) and 0-24 kHz in Argentina], and sounds in broadband recordings (0-200 kHz) were compared to their counterparts in down-sampled narrowband recordings (0-16 kHz). The most robust similarity between sounds present in broadband recordings and their counterparts in the down-sampled narrowband recordings was inter-click interval (ICI); ICI was therefore primarily used to characterize click sounds in narrowband recordings. In NZ and Argentina, distribution of ICIs was a continuum, although the distribution of ICIs in NZ had a somewhat bimodal tendency. In NZ, sounds that had smaller mean ICIs were more likely to have constant ICIs, and less likely to have increasing or decreasing ICIs. Similar to some other delphinids, dusky dolphins may use single, short duration sounds that have a constant ICI and closely spaced clicks for communication. No whistles were documented at either study site. Temporally structured sequences of burst pulses (i.e., sounds with ICI < about 10 ms) also occurred at both study sites, and these sequences contained 2-14 burst pulses that appeared closely matched aurally and in spectrograms and waveforms.

    A 12-year old mixed breed neutered bitch from Misiones, Argentina, was presented with a history of fever and epistaxis. Blood, bone marrow, and lymph node samples were collected for hematology and cytology. Mild regenerative anemia was recorded and large, round, poorly stained piroplasms (>2.5 μm) were found within erythrocytes in blood and lymph node smears. Nested PCR-RFLP on blood and bone marrow samples was positive for piroplasm DNA. The 18S rRNA gene of piroplasms was targeted. A restriction pattern of a previously unreported piroplasm was observed. The PCR product was sequenced, and the sequence obtained had 99% identity with the Rangelia vitalii sequences from Brazil when compared by BLAST analysis. Further characterization of the detected piroplasm consisted of nearly full-length sequencing (1668 bp) of the 18S rRNA gene of this organism. Those sequences were deposited in GenBank. A phylogenetic analysis indicated that they clustered together with R. vitalii from Brazil but separately from large Babesia species of dogs such as Babesia canis, and from species of Theileria of dogs as well. This is the first report of R. vitalii infection in Argentina, and the first case of canine rangeliosis diagnosed outside Brazil. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    The aim of this paper is to analyze the relationship between excess weight and the condition of disability among elderly people in Argentina and to assess the extent to which a protective factor could be operating that reduces or mitigates the effect of overweight on the loss of functional skills in people over 64 years of age. In order to do so, microdata from Argentina's 2009 National Survey of Risk Factors [Encuesta Nacional de Factores de Riesgo] was utilized. To measure the association among overweight, obesity and disability status, as well as the interaction of weight status and age, logistic regression models were estimated. The results indicate that although overweight and obesity have a positive net effect on the occurrence of disabilities, this effect is lower among people 64 years of age and older. This result could be suggesting that among older people a protective factor is at work that, while not reversing the direct relationship between excess weight and disability, seems to attenuate it.

    In recent years mining has expanded significantly in Argentina due to many developments, which include elimination, or reduction to reasonable levels, of a very high level of economic instability. It was a situation that lasted for many decades and that made it very difficult to plan or calculate taxes during the term of a project. Nevertheless, a very important legal security for property rights-which included mining-existed, together with the absence of expropriations. The world and regional conditions with respect to the globalization of activities changed in many ways: the international trade accords such as Mercosur, communications, transportation, the easy access to information through data processing, satellites, etc. Nationalism and the monopolistic statism-with an emotional rejection to foreign capital-have almost disappeared, especially in Argentina. It should be mentioned that the main state companies, i.e. oil, gas, airlines, coal, maritime companies, water, electricity, steel, etc., had the national colors in their logos. In this circumstance, the European concept was followed, without its efficiency and administrative culture. Now, irreversibly, the state manager disappears, and the economy opens-together with the free flow of capital to enter and leave. Convertibility and the set of rules related to mining created a framework necessary for the mining sector`s awakening and the beginning of development of important projects such as Bajo de la Alumbrera and Salar del Hombre Muerto.

    Dengue (DEN) reemergence was first detected in Salta, Argentina, in 1997. It was confirmed by serology and PCR that DEN-2 virus was responsible for sporadic cases and indigenous transmission. A laboratory-based surveillance system allowed the detection of an outbreak in Salta several months later. In total, 378 DEN cases were laboratory diagnosed out of 646 (58%) studied. The cases were distributed in 10 localities of the province between January 3rd and May 31st, 1998. One DEN-2 viral isolation and 4 PCR products were obtained from patients coming from Orán and Embarcación localities. Male and female cases occurred at a similar rate (1:1), with adult cases (82.5%) nearly five times greater than for children under 15 years-old (17.5%). Clinically, all cases corresponded to classic DEN. This is the first time that a DEN outbreak has been laboratory-diagnosed in Argentina and also the first time that DEN virus has been isolated in this country.

  2. A new calymmate mimosoid polyad from the Miocene of Argentina.

    A palynomorph with an unequivocal relationship to the eight-grain polyads of the mimosoid genus Calliandra Benth., is described from the Miocene sediments of San Juan Province, Argentina. Comparison of the fossil palynomorph with polyads of the extant Calliandra species shows a resemblance to those which have one, highly specialized, appendiculate monad. The new palynomorph has a rudimentary appendix, apparently transitional in the path leading to the more highly developed appendiculate forms in the extant Calliandra group. This specialized polyad type is considered to be one of the most highly evolved forms in subfamily Mimosoideae. The closest affinity of the new fossil polyad is with the eight-grain calymmate polyads of Calliandra chilensis Benth., a species which has developed in the extra-tropical, xerophilous shrub, habitat of north-central Chile. The disappearance of Calliandra species in San Juan Province is thought to be related to the culmination of the Andean rising, and the consequent interruption to the Pacific Ocean climatic influence. This new discovery is the first fossil record of Calliandra for Argentina, as well as being the most southerly and the oldest. It reinforces the hypothesis of an early origin and diversification for the Leguminosae in Tropical America.

  3. The programs and context of medical education in Argentina.

    There are 29 medical schools in Argentina (this number has increased rapidly in the last decade) offering a 6-year curriculum that usually consists of 3 years of basic science, 2 years of clinical sciences, and one internship year. Annually, 5,000 physicians graduate from these programs. Admission requirements vary depending on each university's policy. Some do not have entry requirements; others require a course, usually on the basics of mathematics, biology, chemistry or physics, and some introduction to social and humanistic studies. Each year, there are approximately 12,000 first-year medical students attending the 29 schools, which suffer a high dropout rate during the first years because of vocational problems or inability to adapt to university life. Some schools have massive classes (over 2,000 students), which makes it difficult for the schools to perfect their teaching. The number of full-time faculty members is low, and some of them have appointments at more than one medical school. Residency programs offer an insufficient number of places, and fewer than 50% of the graduates can obtain a residency position because of strict admission requirements. Coordination between the Ministry of Health, representing the health care system, and the Ministry of Education, representing the medical education system, needs to be improved. Despite the problems of medical education in Argentina, the movement to improve the education of health care workers is growing. The author offers two recommendations to help accomplish this goal.

    The Argentinean Society of Paediatrics introduced in 1993 a continuing professional development (CPD) programme to raise standards of clinical practice. The aims of the project were to introduce a structured, distance learning programme accessible to all paediatricians in the country, but especially for those working far from centres of paediatric excellence. The programme is planned on an annual basis. It includes four activities: a written manual designed by a team of medical experts and educationalists comprising 12topics; field work for participants; annual meetings in several locations in the country for discussion of the subjects; and an evaluation based on centrally designed multiple choice questions distributed by mail. In spite of a registration fee of £90 a year, participation in the programme increased from 3357 in 1993 to 4126 in 1996, from a membership of 10 216 paediatricians in Argentina. The popularity of the programme may result from an appropriate interpretation of professional needs of paediatricians in Argentina, adequate organisational arrangements that reach all colleagues, including those working in remote areas, and a genuine motivation of paediatricians for participating in a learning process.

    A systematic review of surveys performed between 1980 and 2011 (published in MEDLINE/Pubmed and/or LILACS indexed journals, available in the baseline data from a Mass Deworming National Program (MDNP, 2005) was used to identify the prevalence, distribution and detection of risk areas for soil transmitted helminth infections (STH) in Argentina. We found 310 publications in the database using the pre-defined key-words (medical subject headings) for research purposes. Only 24 articles with 26 surveillance sites in 8 provinces and a total of 5495 surveyed individuals fulfilled the inclusion criteria. Frequency rates for STH had a wide range: Ascaris lumbricoides: 0-67%, hookworms: 0-90%, Trichuris trichiura: 0-24.6 and Strongyloides stercoralis: 0-83%. The estimated combined incidence varied from 0.8% to 88.6%. Baseline surveys from the MDNP reporting on 1943 children from 12 provinces confirmed the heterogeneity, with combined STH frequency rates ranging from 0 to 42.7%. Surveys included in this review showed that the distribution of STH in Argentina is not homogeneous, with areas of high incidence (> 20%) in the northeastern and northwestern provinces where mass deworming activities would be highly beneficial. In several surveys, the high overall incidence was mostly due to hookworms and S. stercoralis, a situation to be considered when selecting diagnostic and therapeutic control strategies. The scarcity or absence of data from various provinces and the availability of less than 8000 surveyed individuals should be considered.

    Sirenomelia is a severe malformation of the lower body characterized by a single medial lower limb and a variable combination of visceral abnormalities. Given that Sirenomelia is a very rare birth defect, epidemiological studies are scarce. The aim of this study is to evaluate prevalence, geographic clusters and time trends of sirenomelia in Argentina, using data from the National Network of Congenital Anomalies of Argentina (RENAC) from November 2009 until December 2014. This is a descriptive study using data from the RENAC, a hospital-based surveillance system for newborns affected with major morphological congenital anomalies. We calculated sirenomelia prevalence throughout the period, searched for geographical clusters, and evaluated time trends. The prevalence of confirmed cases of sirenomelia throughout the period was 2.35 per 100,000 births. Cluster analysis showed no statistically significant geographical aggregates. Time-trends analysis showed that the prevalence was higher in years 2009 to 2010. The observed prevalence was higher than the observed in previous epidemiological studies in other geographic regions. We observed a likely real increase in the initial period of our study. We used strict diagnostic criteria, excluding cases that only had clinical diagnosis of sirenomelia. Therefore, real prevalence could be even higher. This study did not show any geographic clusters. Because etiology of sirenomelia has not yet been established, studies of epidemiological features of this defect may contribute to define its causes.

    The appearance of the vector of visceral leishmaniasis (VL) Lutzomyia longipalpis in the province of Formosa in 2004 was associated with urban epidemic risk for the first time in Argentina. During 2006, vectors, canine and human cases of VL were reported in the province of Misiones, and in summer 2008-2009, in the province of Corrientes. In Santiago del Estero province in 2008, cases of human and canine VL were associated with secondary vectors. Therefore, with the aim to know the current distribution of VL risk in the Chaco region, systematic captures of the vector were performed between January and April 2010 in 30 localities of Formosa and Chaco, and in the city of Reconquista, province of Santa Fe (224 traps/night). Lu. longipalpis was reported for the first time in the cities of Resistencia and Puerto Antequera (Chaco). Clorinda and Puerto Pilcomayo (Formosa) are the localities where the traps with more individuals were obtained, 158 and 241 Lu. longipalpis trap / site / night respectively. These results showed that the vector of urban epidemic VL is still spreading in Argentina, and already reached the province of Chaco. Sporadic cases reported in the Chaco region, transmitted by secondary vectors as Lu. migonei would also increase due to intensified surveillance, and the dispersion of the parasite associated with the transit of asymptomatic or symptomatic infected dogs.

    The status of resistance to cyromazine, 2,2-dichlorovinyl dimethyl phosphate (DDVP), and permethrin relative to field populations of the house fly, Musca domestica L. from Argentinean poultry farms was studied. All the three studied populations (SV, Q, and C) showed resistant ratios (RRs) to cyromazine of 3.9, 10.98, and 62.5, respectively. We observed high levels of resistance toward the organophosphate DDVP and permethrin. The RRs to DDVP ranged from 45.4 to 62.5. No significant differences were found among the studied populations. All the house fly populations were permethrin-resistant, in comparison with the susceptible strain. Two of the analyzed populations (SV and Q) differed significantly in toxicity to the population C. This is the first evidence that house flies from Argentina showed a multi-resistance pattern. The implementation of an insecticide monitoring program on poultry farms of Argentina is needed to prevent field control failures. Furthermore, integrated control strategies are needed to delay detrimental development of insecticide resistance.

    Between 1987 and the date of the present issue, 10 reports have been published on the prevalence of the vitamin D deficit in Argentina. These studies were done investigating new born babies, children, adolescents, and healthy and institutionalized adults, living in southern, middle or northern cities of Argentina. The weighed prevalence of vitamin D deficit in those reports was 43.3% (436/1007). This figure may be lower than reality because it is not known whether the stratification (age and location of residence) of the sum of samples agree with that of the national population. Taking into account the obvious difficulties in carrying out such a research two areas for further research are suggested: a) an investigation on the solar exposure in summer needed to obviate (or not) the oral supplementation of vitamin D in winter, b) to determine the success of the schema of administration taking into account the current controversy between dose and optimum plasma levels of 25(HO)D3. In both instances, the end point should include some of the physiological functions alluded to in this editorial.

    The aim of this study was to describe an outbreak of Shigella sonnei that occurred in the city of Lujan, Buenos Aires, Argentina, in July 2012. Five individuals were affected after eating a hand-made Viennese-style pastry at a family gathering. All of them presented with fever, joint pain, chills and non-bloody diarrhea containing mucus. Stool cultures were performed in all cases and the samples taken from the pastry ingredients were analyzed microbiologically. S.sonnei was isolated and identified in all the patients involved as well as in the almond cream filling. The isolates were analyzed for determining the antimicrobial susceptibility and genetic profiles by pulsed field gel electrophoresis (PFGE). The results showed the genetic relationship among the isolates, confirming that the cases occurred due to the patients' exposure to the same source of infection, i.e., the almond cream. Being the almond cream an industrially-manufactured ingredient, an initial contamination could have been unlikely; however contamination might have occurred as a result of manipulation in the bakery.

    Larvae of necrophagous flies in the families Calliphoridae, Sarcophagidae and Muscidae are the main exploiters of decaying organic matter. Knowledge of insect species associated with each stage of decay can be used to estimate the time since death in the crime scene. Dipteran larvae are attacked by a rich community of parasitoids, including species of Braconidae, Ichneumonidae and Pteromalidae (Hymenoptera: Parasitica). This study examined the parasitic complex associated with flies of forensic and sanitary importance in the city of Córdoba (Argentina). Sampling was conducted at two sites with different urbanization levels from December 2012 to March 2013; parasitoids were collected using fly traps baited with beef liver. Rates of parasitism and of parasitized pupae were estimated and species composition was analyzed for both communities. Sarcophagidae was the most abundant family, represented by two species, followed by Calliphoridae. Nasonia vitripennis Ashmead (Hymenoptera) was the most abundant species and was collected from a wider variety of hosts. To the best of our knowledge, this is the first study providing accurate information about trophic interactions between calyptrate dipteran species and their hymenopteran parasitoids in central Argentina.

    We present here a short review of the main work which has been done in the latest years in neutron imaging in Argentina, and the future plans for the development of this technique in the country, mainly focused in the design of a new neutron imaging instrument to be installed in the future research reactor RA10. We present here the results of the implementation of the technique in samples belonging to the Argentinean cultural heritage and experiments related with hydrogen storage. At the same time, the Argentinean RA10 project for the design and construction of a 30 MW multipurpose research reactor is rapidly progressing. It started to be designed by the National Atomic Energy Commission (CNEA) and the technology company INVAP SE, both from Argentina, in June 2010. The construction will start in the beginning of 2015 in the Ezeiza Atomic Center, at 36 km from Buenos Aires City, and is expected to be finished by 2020. One of the main aims of the project is to offer to the Argentinean scientific and technology system new capabilities based on neutron techniques. We present here the conceptual design of a neutron imaging facility which will use one of the cold neutron beams, and will be installed in the reactor hall. Preliminary simulation results show that at the farthest detection position, at about 17 m from the cold source, a uniform neutron beam on a detection screen with an intensity of about 108 n/cm2/s is expected.

    Canine distemper virus (CDV) has been reported worldwide in wild carnivores and has been cited as the cause of population declines in some species. Crab-eating foxes (Cerdocyon thous) from El Palmar National Park, Argentina, were observed either dead or exhibiting clinical neurologic signs. Samples were taken from two individuals that were laterfound tobe positive for CDV by direct immunofluorescence in brain tissue. Based on molecular studies, the CDV strain had a high percentage of identity compared to CDV strains affecting dogsin Argentina. This is the first report of CDV infection in wild carnivores in Argentina.

    Species of Philornis Meinert, 1890 (Diptera, Muscidae) are Neotropical dipterans that include species with parasitic larvae which feed on nestling birds. To date, all Philornis species that have been recorded from Argentina have parasitic subcutaneous larvae. Here, for the first time for Argentina, we report the finding of Philornis downsi Dodge & Aitken, 1968, a fly with a nest-dwelling, semi-haematophagous larva. This record, from the humid Chaco ecoregion of Argentina in the nest of a saffron finch Sicalis flaveola pelzelni Sclater, substantially extends the known distribution of this species. We also report the consensus sequences of the internal transcribed spacer 1 (ITS1) and ITS2 regions of three of the specimens for future reference and comparison. Further investigation is needed to determine whether Argentina is part of the historical range of P. downsi or, alternatively, represents a recent expansion of its range, perhaps due to climatic changes or other factors of global environmental variation.

    Rotavirus is a leading cause of severe diarrhea in children under 5. In Argentina, the most affected regions are the Northeast and Northwest, where hospitalizations and deaths are more frequent. This study estimated the cost-effectiveness of adding either of the two licensed rotavirus vaccines to the routine immunization schedule. The integrated TRIVAC vaccine cost-effectiveness model from the Pan American Health Organization's ProVac Initiative (Version 2.0) was used to assess health benefits, costs savings, life-years gained (LYGs), DALYs averted, and cost/DALY averted of vaccinating 10 successive cohorts, from the health care system and societal perspectives. Two doses of monovalent (RV1) rotavirus vaccine and three doses of pentavalent (RV5) rotavirus vaccine were each compared to a scenario assuming no vaccination. The price/dose was US$ 7.50 and US$ 5.15 for RV1 and RV5, respectively. We ran both a national and sub-national analysis, discounting all costs and benefits 3% annually. Our base case results were compared to a range of alternative univariate and multivariate scenarios. The number of LYGs was 5962 and 6440 for RV1 and RV5, respectively. The cost/DALY averted when compared to no vaccination from the health care system and societal perspective was: US$ 3870 and US$ 1802 for RV1, and US$ 2414 and US$ 358 for RV5, respectively. Equivalent figures for the Northeast were US$ 1470 and US$ 636 for RV1, and US$ 913 and US$ 80 for RV5. Therefore, rotavirus vaccination was more cost-effective in the Northeast compared to the whole country; and, in the Northwest, health service's costs saved outweighed the cost of introducing the vaccine. Vaccination with either vaccine compared to no vaccination was highly cost-effective based on WHO guidelines and Argentina's 2011 per capita GDP of US$ 9090. Key variables influencing results were vaccine efficacy, annual loss of efficacy, relative coverage of deaths, vaccine price, and discount rate. Compared to no

    This conference provided a forum for information exchange and discussions between researchers within the various IR technologies and engineers active in IR system developments. Participants reported advances in all the major technologies and discussed the use of hybrid refractive/diffractive optical systems; the inclusion of diffractive elements will lead to a reduction in system volume, weight, and cost. Measured and predicted performances of four classes of focal-plane detector arrays were compared, including superconducting and room-temperature bolometers as well as superconducting and semiconductor quantum detectors. Reports were heard on lightweight detector coolers requiring low input power and having operating lifetimes of about 5,000 hours and on processing algorithms for reducing the false alarm rate in IR search systems. Signal processing on and off the focal plane was a critical technology. Separate abstracts were prepared for 50 papers in this conference.

    XIX International Scientific Symposium in honor of Academician M.A. Usov ''Problems of Geology and Subsurface Development'' (for students and young scientists) was organized under the guidance of the Ministry of Education and Science of the Russian Federation and the Russian Foundation for Fundamental Research within the National Research Tomsk Polytechnic University (NR TPU). TPU is one of the oldest technical higher education institutions in Russia, training specialists in the domain of geoscience and enhancing their further research in this area. The Institute of Natural Resources, National Research Tomsk Polytechnic University (INR TPU) was chosen to hold the International Scientific Symposium. In 2015 the Institute of Natural Resources celebrated its 114th anniversary. It was founded by V.A. Obruchev in 1901, first Siberian geologist, member of USSR Academy of Sciences, Hero of Socialist Labor, and first Laureate of the Lenin Prize. He was recognized as a prominent scientist in the area of geology all over the world. INR is the first institute of geological education and geosciences in Asian Russia. Even today the Siberian Mining and Geological School, established by V.A. Obruchev and M.A. Usov, has retained its significance in the discovery, exploration and development of mineral resources not only in Siberia, the Far East and North-East of Russia, but also in Central Asia. There are numerous outstanding scientists and engineers among alumni of The Institute of Natural Resources. The institute is proud of such outstanding people as: M.A. Usov, student and first postgraduate of V.A. Obruchev, first professor and academician in Siberia, whose name is associated with the mining industry in Siberia; Academician K.I. Satpaev, founder and first president of the Academy of Sciences of Kazakhstan; Professor N.N. Urvantsev, discoverer of the unique Norilsk ore deposits in the North of East Siberia and Professor M.K.

    Honeybees are threatened by various pathogens and parasites. More than 18 viruses have been described in honeybees and many of them have been detected in China and Argentina. In China, both Apis cerana and Apis mellifera are raised. In Argentina, beekeepers raise different ecotypes of A. mellifera: European honeybees (in both temperate and subtropical regions) and Africanised honeybees (in subtropical areas only). A thorough study was carried out in both China and Argentina to analyse the current virus presence and distribution in different climatic zones and gather information on different bee species/subspecies. Adult honeybees were collected from apiaries in temperate and subtropical regions of China (including areas with exclusive populations of A. mellifera, areas where A. mellifera and A. cerana co-exist, and areas with exclusive populations of A. cerana) and Argentina. Six viruses, namely, deformed wing virus (DWV), black queen cell virus (BQCV), sacbrood virus (SBV), chronic bee paralysis virus (CBPV), acute bee paralysis virus (ABPV) and Israeli acute paralysis virus (IAPV) were detected in China, both in A. cerana and in A. mellifera, while four viruses (DWV, BQCV, CBPV and ABPV) were present in Argentina. Interestingly, multiple infections were commonly found in China, with up to five different viruses co-circulating in some colonies without apparent abnormalities. In this study, no Chinese samples were positive for slow bee paralysis virus. The most prevalent viruses were BQCV (China) and DWV (Argentina). Kashmir bee virus was absent from samples analysed for both countries.

  10. Treating without diagnosis: Psychoanalysis in medical settings in Argentina.

    This article is part of a larger research project, the aim of which is to understand the discursive conditions of access and adherence to an outpatient mental health service at a public hospital in Buenos Aires, Argentina. The focus is on the historical conflict between medical discourse and psychoanalytical discourse as it emerges in the negotiation of treatment and diagnostic sequences at first consultations. It can be seen that patients who are socialized in medical discourse--and even in psychiatric discourse--expect the usual procedure in which a diagnosis, however transitory, is offered first and then followed by a treatment recommendation. However, psychoanalysts, in contrast, tend to reject diagnostic labels and offer treatment without further justification. This has an impact on the adherence of patients, and we can argue for the need to negotiate with medical discourse in order to guarantee engagement and continuity in treatment.

    The use of monodose (800 mg) per os of Norfloxacin was evaluated in 32 patients with cholera at Salvador Mazza's Hospital, Salta, Argentina. It was considered the celerity in negativization of stool culture (100% of cases: 12 hours post administration), it efficiency along time (24/24 controlled patients were negative at 10th day) and MIC of isolated strains (100% of strains were sensitive: range 0.008 to 0.016 micrograms/ml). It was included oral administration of sorbitol 70% in peanut oil in order to study patients at 10th day's control. This method could be an alternative one in the study of asymptomatic carrier. Norfloxacin monodose shows good performance in early negativization of stool culture and it was also effective along the whole observation period, suggesting it could prevent carriage.

     The emergence of zoonotic visceral leishmaniasis (ZVL) in Latin America is a growing public health problem. The urbanization of ZVL has been observed in different countries around the world, and there are a growing number of reports drawing attention to the emergence of this infection in new locations, as well as its increase in previously established areas of endemicity. In the city of Posadas, Misiones province, Northeastern Argentina, the transmission of ZVL associated with canines and Lutzomyia longipalpis was first reported in 2006. In the city of Puerto Iguazú, also in Misiones province, the first human case of ZVL was reported in February 2014. From 209 surveyed dogs, 15 (7.17%) were identified as positive by serological and/or parasitological methods. Amplification was observed in 14 samples and in all cases the species implicated was Leishmania infantum. To the authors’ knowledge, this is the first molecular characterization of L. infantum from dogs in this area. PMID:25923899

    Reinfestation by Triatoma infestans after insecticide spraying has caused elimination efforts in the dry Chaco region to fail repeatedly. The sources and spatial extent that need to be considered to understand the reinfestation pattern and to plan a comprehensive control program were studied in 2 adjacent rural communities in northwestern Argentina from 1993 to 1997. The effects of external, residual, and primary sources on the reinfestation pattern were evaluated by using geographic information systems, satellite imagery, spatial statistics, and 5-year retrospective data for 1,881 sites. The reinfestation process depended on primary internal sources and on surrounding infested communities. In the dry Chaco, successfully reducing the risk for reinfestation in a community depends on treating all communities and isolated sites within 1,500 m of the target community. In addition, during the surveillance phase, spraying all sites within 500 m of new foci will delay reinfestation. PMID:16836826

    Previously treated as species of Pseudalopex, Argentine members of the genus Lycalopex (L. griseus, L. gymnocercus, and L. culpaeus) are examined to clarify the taxonomic status of each named form. Principal components analyses of 26 cranial measurements of 151 adult specimens and 11 pelage characters of 111 specimens, clearly distinguish L. culpaeus from the other two taxa. Lycalopex griseus and L. gymnocercus show clinal variation in cranial measurements and pelage characters. Qualitative cranial characters, used as diagnostic for L. griseus and L. gymnocercus, revealed great nongeographic variation. We conclude that L. griseus and L. gymnocercus are conspecific, and should be known as L. gymnocercus. Therefore, we recognize only two species of the genus Lycalopex (L. culpaeus and L. gymnocercus) in Argentina. We also use this opportunity to review synonymies of the recognized species of Lycalopex.

    The arbuscular mycorrhizal fungal (AMF) communities from the Yungas forests of Argentina were studied. The AMF species present in the rhizosphere of some dominant native plants (one tree: Alnus acuminata; three herbaceous species: Duchesnea indica, Oxalis conorrhiza, Trifolium aff. repens; and one shrub: Sambucus peruviana) from two sites (Quebrada del Portugués and Narváez Range) of the Yungas forests were isolated, identified and quantified during the four seasons of the year. Twenty-two AMF morphotaxa were found. Spore density of some AMF species at each site varied among seasons. The genera that most contributed to the biodiversity index were Acaulospora for Quebrada del Portugués and Glomus for Narváez Range. High diversity values were observed in the Yungas forests, particularly in the spring (rainy season). We concluded AMF differed in species composition and seasonal sporulation dynamics in the Yungas forests.

    Five species of sigmodontine rodents have been identified in Argentina as the putative reservoirs of six circulating hantavirus genotypes. Two species of Oligoryzomys are associated with the genotypes causing hantavirus pulmonary syndrome, Oligoryzomys flavescens for Lechiguanas and O. longicaudatus for Andes and Oran genotypes. Reports of human cases of hantavirus pulmonary syndrome prompted rodent trapping (2,299 rodents of 32 species during 27,780 trap nights) at potential exposure sites in three disease-endemic areas. Antibody reactive to Sin Nombre virus was found in six species, including the known hantavirus reservoir species. Risk for peridomestic exposure to host species that carry recognized human pathogens was high in all three major disease-endemic areas. PMID:10603213

    2011-07-01

    The ability of soil microorganisms to solubilize phosphate is an important trait of plant growth-promoting bacteria leading to increased yields and smaller use of fertilizers. This study presents the isolation and characterization of phosphobacteria from Puna, northwestern Argentina and the ability to produce phosphate solubilization, alkaline phosphatase, siderophores, and indole acetic acid. The P-solubilizing activity was coincidental with a decrease in pH values of the tricalcium phosphate medium for all strains after 72 h of incubation. All the isolates showed the capacity to produce siderophores and indoles. Identification by 16S rDNA sequencing and phylogenetic analysis revealed that these strains belong to the genera Pantoea, Serratia, Enterobacter, and Pseudomonas. These isolates appear attractive for exploring their plant growth-promoting activity and potential field application.

    It is pointed out that the 1977 Caucete earthquake was an east-west compressive event which occurred at a depth of about 17 km in the Andean back arc approximately 450 km east of the Chile trench. The present study is primarily concerned with the mechanics of fault behavior prior to and after the 1977 earthquake, as evidenced by preseismic and postseismic vertical deformation. Simple fault models for each phase of deformation are presented. The models of preseismic slip, coseismic slip, and postseismic slip consist of uniform dislocations in an elastic half-space following the method of Chinnery (1961). The basically elastic models presented demonstrate that deformations in the vicinity of the 1977 Caucete, Argentina, earthquake are consistent with activity on some portion of the coseismic fault. This is evidence that these deformations are directly related to the processes of strain accumulation and release associated with the event.

    Bajada del Diablo is located in the Northern Patagonian Massif, Chubut, Argentina. The study area includes several circular structures found in Miocene olivine basalts of the Quiñelaf Eruptive Complex and in the Late Pliocene/Early Pleistocene Pampa Sastre conglomerates. An impact origin has been proposed for these circular structures. With the aim of further investigate the proposed impact origin, topographic, gravimetric, magnetic, resistivity, palaeomagnetic and electromagnetic surveys in two circular structures (`8' and `G') located in Pampa Sastre conglomerates and in basalts of the Quiñelaf Eruptive Complex were carried out. The new geophysical results support the hypothesis of an impact origin. However, the confirmation of such an origin through the findings of shock metamorphism evidences and/or the recovery of meteorites remains elusive.

    Fluoroquinolone resistance is a growing problem that has only recently emerged in S. agalactiae. Between 2005-2007, WHONET--Argentina network evaluated levofloxacin susceptibility in 1128 clinical S. agalactiae isolates, 10 (0.9%) of which proved to be resistant. Nine of them had come from 5 hospitals (in Buenos Aires City and 4 Argentinean provinces) and recovered from urine (n=7) and vaginal screening cultures (n=2). Three strains were also resistant to macrolides, lincosamides and B streptogramins due to the ermA gene. All nine fluoroquinolone-resistant isolates bore the same two mutations, Ser79Phe in ParC and Ser81Leu in GyrA proteins. Genetic relationships were analyzed by Apal-PFGE and two clones were determined, A (n=6) and B (n=3). To our knowledge, these are the first fluoroquinolone-resistant S. agalactiae isolates detected in Latin America.

    Primary care should be the cornerstone of any health system. It is the first contact with the community health system of any country. The Declaration of Alma-Ata, 1978, seeks to provide the basis for the construction of a new health system that will allow the full exercise of the right to health. Carrying out an external rotation in Primary Care in Posadas, Misiones Province, Argentina, during medical training, in family medicine, offers an insight into how other health systems work, provide health care to the community in a Primary Care Center in a country with its similarities and differences like ours, follow the implementation of programs, working with family medicine residents in another country, and living a rewarding personal and professional experience.

    Confronted with the need for accessible sources of good quality water and in view of the fact that the threat to public health posed by arsenic occurs mainly through the ingestion of contaminated drinking water, the presence and distribution of arsenic was evaluated in the southern Pampa Plains of Bahía Blanca district in Argentina. The findings show variable concentrations of arsenic in a complex distribution pattern. Complementary information is provided on the behavior of the groundwater resource and its salinity in terms of dissolved ions. Groundwater is the most severely affected, 97% of the samples exceeding the guideline value for arsenic in drinking water as recommended by the WHO (Guidelines for Drinking Water Quality, 2004). and showing maximum concentrations of up to 0.30 mg/L. Informing those responsible for preventive medicine and alerting the community at large will facilitate measures to mitigate exposure and ensure the safety of drinking water. PMID:19936127

    Argentina has an over 60-year history of food programs which have received few to no evaluations, even considering the highly important epidemiological and social changes that have occurred in the target population. In this article, nationwide State-run food programs with the objective of contributing to the food security of the families in greatest need are reviewed, the nutritional situation of the target population is reassessed, and arguments for analyzing current programs using a typology based in the components of food security are proposed. A general review of the conceptions, content and reach of food programs should be carried out, in order for these programs to cease to act as mere social assistance and instead be transformed in bearers of the right to better food and nutrition.

    We report a large case series of hantavirus pulmonary syndrome (HPS) in Argentina that was confirmed by laboratory restuls from 1995 through 2008. The geographic and temporal distribution of cases by age, sex, fatality rate, and risk factors for HPS was analyzed. A total of 710 cases were unequally distributed among 4 of the 5 Argentine regions. Different case-fatality rates were observed for each affected region, with a maximum rate of 40.5%. The male-to-female ratio for HPS case-patients was 3.7:1.0; the case-fatality rate was significantly higher for women. Agriculture-associated activities were most commonly reported as potential risk factors, especially among men of working age. Although HPS cases occurred predominantly in isolation, we identified 15 clusters in which strong relationships were observed between members, which suggests ongoing but limited person-to-person transmission.

    Saccharosydne is the most diverse genus of the tribe Saccharosydnini. Male, female and nymphal Saccharosydne have been captured in recent collections from garlic (Allium sativum), rye (Secale cereale) and pampas grass (Cortaderia spp.) in Argentina. In this contribution, we describe and illustrate a new species S. subandina sp. nov., adding information on the geographical distribution and host plants. Saccharosydne subandina can be distinguished from its congeners by the following combination of features: uniformly light green-yellowish color with a distinctive rounded black macula on both genae; vertex 1.5x longer than wide, and projecting beyond eyes almost one half of its length; parameres divergent with internal and external angles acute; and dorsolateral angles of pygofer produced caudad. A key for species identification based on male genitalia and external morphology, is provided.

    The aliphatic hydrocarbon fractions of sixty oils from the San Jorges Basin, Argentina have been analysed by computerized-gas chromatography-mass spectrometry. The initial aim of this study was the correlation of the oils using sterane and triterpane biomarkers. The oils could be divided into four groups which were distinguished by the relative proportions of regular to demethylated hopanes. Although it has been previously suggested that the demethylated hopanes found in oils could have resulted from biotransformation of the oils in the reservoir, in this basin the possibility that these compounds originated directly from the source beds cannot be entirely eliminated since the oils do not appear to be extensively biodegraded on the basis of their aliphatic hydrocarbon distributions. An alternative theory for the hydrocarbon distributions observed in these oils, is initially biodegradation of the oils in the reservoir followed by addition of non-degraded oil to produce a mixture of degraded and non-degraded oil.

    Killikaike blakei is a new genus and species of anthropoid from the late Early Miocene of southeastern Argentina based on the most pristine fossil platyrrhine skull and dentition known so far. It is part of the New World platyrrhine clade (Family Cebidae; Subfamily Cebinae) including modern squirrel (Saimiri) and capuchin monkeys (Cebus) and their fossil relatives known from Early to Middle Miocene and subrecent periods. Living cebines are relatively large-brained, adroit predatory foragers and live within complex social groups, and wild capuchins exhibit a wide range of behaviors associated with enhanced intelligence. We show that K. blakei lacks diagnostic derived characteristics of the lower face and premolar dentition that are shared by modern cebines, but its strongly vaulted frontal bone and capacious anterior cranial fossa indicate the early evolution of an enlarged forebrain.

    Approaching from the perspective of social and historical construction, the article addresses the professionalization of dentistry in Argentina from the late nineteenth century to 1940. The study analyzes the weight of different actors and dimensions, particularly the introduction of dentistry studies into Argentinean universities and the conflicts between dentists and those in related fields (especially physicians, mecánicos dentales, and informal practitioners like barbers and bleeders) as well as conflicts with the State. The article explores the union, political, and academic strategies developed in an effort to define a space for exclusive intervention, and also looks at the earliest successes in tracing out a specific domain that would ensure professional autonomy and monopoly in the practice of dentistry. A review of documentation reveals the weight of craftsmanship and the mercantile tradition in dental practice, very limited collective participation in the union environment and the field's weak commitment to public health.

    Sampling for chytrids in a variety of habitats has resulted in pure cultures that when analyzed have yielded hypotheses of relationships based on molecular and zoospore ultrastructural markers. To extend our understanding of diversity of Chytridiales in eastern Argentina and USA, we isolated and examined the morphology, ultrastructure and 28S and ITS1-5.8S-ITS2 rDNA sequences of numerous chytrids from aquatic habitats from these two regions. Three family-level lineages (Chytridiaceae, Chytriomycetaceae, family incertae sedis) are represented in our molecular phylogeny, and three new genera (Avachytrium, Odontochytrium in Chytriomycetaceae, Delfinachytrium in family incertae sedis) are described. These findings of new genera and species emphasize the potential for discovery of additional diversity.

    Historical researches focusing on the study of the ideas on madness and on psychiatry as a medical specialty in Argentina published until 1980 were few, and they were scattered throughout a time period covering more than a century. Some of them, however, constituted sources of useful data that contributed to subsequent developments which are still, in great measure, under way. New collective projects adopting new methodological approaches to address the subject have emerged in recent years. In this respect, the establishment of a vast plan for the research and compilation of primary sources, the organization and development of a formation of human resources that may adequately meet future research work, and a more solid assurance of the publication and divulgement of this research work are still pending. This article, of an introductory nature and predominantly descriptive and panoramic, reviews the main works and authors and their theoretical conceptions, situating them in the context of their time.

    Celestite-barite occurrences of early Cretaceous age were studied in the Extra-Andean region of Neuquén, West central Argentina. The ores are located in a Subandean Mesozoic belt and show a conspicuous stratabound character related to evaporitic facies. The study of the geologic evolution of the sedimentary sequence allows prediction of the temporal and spatial setting of the evaporitic facies. Stratigraphy is the main geologic control for the celestite-barite ores and their areal distribution depends on the structure of the region. Based on the geometry and texture of the mineralization three types of ores have been recognized: 1) celestite beds syngenetic with the evaporitic facies; 2) epigenetic stratabound ores formed by "in situ" mobilization of celestite with stalactite growth and cavity infilling; 3) epigenetic vein-type ores formed by mobilized barium enriched solutions. Lithofacies and isotopic 87Sr/86Sr analyses together with the geological evidence confirm an evaporitic origin for the celestite beds.

    Within an ambitious construction program, required to implement a new basic education system in Argentina, three energy efficient demonstration school buildings are presently being built in the province of Mendoza, on the arid, central-western region of the country. One of the projects is presented in this paper, being its main goal to provide maximum environmental comfort, thermal and luminous, with minimum use of conventional energy, in the primary spaces of the building. The use of the locally available technology was maximized in the implementation of passive systems with minimum requirements for control or automation. The design was evaluated and adjusted, along its development process, using well known calculation and simulation tools. Anticipated percentual energy savings values are: 87.1% in natural gas for space heating and 82.2% in electricity for lighting. Unit construction costs were compatible with those resulting from bidding of conventional school building projects, within the same program.

    Migration of HIV infected individuals from cities to small towns and rural areas spreads AIDS among non urban population, superimposing HIV with other endemic or epidemic infections as parasitoses. This situation is a big challenge to public health because in most cases the association between these infections worsens both prognoses. We present here the first case in Argentina of AIDS associated to a mucocutaneous form of American tegumentary leishmaniasis. The patient was from Orán, an area where in the middle eighties, an epidemic outbreak took place. By now more than 2000 cases have been parasitologically confirmed in our Institute and the causing species were identified as Leishmania (V.) braziliensis and L. (L.) amasonensis. Considering the existence of co-infection of HIV and Leishmania, it is recommended that in patients from endemic areas with records of cutaneous or mucocutaneous ulcers, even healed, leishmaniasis must be investigated, among other diseases.

    ABSTRACT The obesity epidemic is rapidly advancing in South America, leading to inevitable health consequences. Argentinian and Brazilian health policies try to become adapted to the new economic and social framework that follows from this epidemic. It is in incipient and ineffective control so far since the prevalence of obesity was not restrained. The Argentine national legislation is more advanced, through the so-called “Ley de Obesidad.” In Brazil, there are numerous local initiatives but still not a comprehensive law. National policies relating to decisions regarding obesity are discussed in this paper. Trends in decisions issued in higher courts of Argentina (Supreme Court of Justice of the Nation—CSJN) and Brazil (Supreme Court of Justice—STF), in the last 15 years, seek to clarify the approach of each country and court's resolutions. Marked differences were found in their positions. Finally, legal and health solutions to this obesity epidemic are proposed. PMID:25076669

    A small to medium-sized pterodactyloid pterosaur (wingspan approximately 1.10 m) from the Upper Jurassic (middle-late Tithonian) marine deposits of the Vaca Muerta Formation of Patagonia (Los Catutos area, central Neuquén Province, Argentina) is reported. The specimen lacks the skull but constitutes a nearly complete postcranial skeleton, which includes cervical and dorsal vertebrae; a few thoracic ribs; both pectoral girdles; the left pelvic girdle; a proximal right wing (humerus, ulna, and radius) and metacarpal IV; a left wing that lacks only wing phalanx four; and both hindlimbs, the right one without the foot. Ontogenetic features suggest that the new fossil corresponds to a relatively mature individual, probably a subadult. Observed characters support its assignment to the Archaeopteroactyloidea, a basal clade within the Pterodactyloidea. This specimen is the second pterosaur from Los Catutos and the most complete Jurassic pterosaur so far known from South America.

    To explore the role of obstetricians and gynaecologists in reproductive public health policies in Argentina. Combination of quantitative methods (survey, n=467) and qualitative methods (semistructured interview, n=35; focus groups, n=6). The great majority of respondents believe that abortion and contraception are serious public health issues. Seven out of 10 considered the implementation of family planning services and post-abortion contraceptive counseling to be priorities. One-half favored promoting social debate on abortion. The great majority thought that de-criminalization of abortion would help to diminish maternal mortality and that abortion should not be penalized when the womans life or health is at risk, or in cases of rape or fetal malformations. Abortion and contraception are important issues for physicians. Advocacy efforts within this community need to focus on an integral vision of health, emphasizing their social responsibility.

    The National Registry of Congenital Anomalies (Registro Nacional de Anomalías Congénitas, RENAC) is a hospital-based surveillance system for newborn infants with major morphological congenital anomalies (CAs). The objective of this study was to describe the characteristics and operation of the RENAC registry and the prevalence at birth of 56 specifc selected CAs, compared to other registries. The organization of the RENAC registry was initiated in public hospitals with 1000 or more births per year or which are the referral hospitals in a determined health region. Neonatologists are in charge of data collection, and a central coordination department is in charge of encoding, statistical analyses and regular reports. The RENAC registry uses an online forum for data submission and for guidance and interaction regarding the initial management of cases. Between November 1st, 2009 and June 30th, 2012, 98 hospitals were included in the registry, the annual coverage of these hospitals is 65% in the public sector and 35% of births in Argentina. In this period, 294 005 newborn infants were examined, and 5165 cases with major CAs were detected (1.76%; 95% CI: 1.71-1.80). The most frequent CAs were septal heart defects (prevalence per 10 000: 28.6), Down's syndrome (prevalence per 10 000: 19.2), cleft lip +/- palate (prevalence per 10 000: 12), and a set of neural tube defects (prevalence per 10 000: 11.9). The RENAC has reached a high coverage in the public sector and the differences in prevalence with other registries can be related to operational aspects or actual differences, depending on the case. The RENAC deals with the collection, analysis and dissemination of information about CAs in Argentina, and also contributes with local interventions.

    Background Physician-implemented interventions for smoking cessation are effective but infrequently used. We evaluated smoking cessation practices among physicians in Argentina. Methods A self-administered survey of physicians from six clinical systems asked about smoking cessation counselling practices, barriers to tobacco use counselling and perceived quality of training received in smoking cessation practices. Results Of 254 physicians, 52.3% were women, 11.8% were current smokers and 52% never smoked. Perceived quality of training in tobacco cessation counselling was rated as very good or good by 41.8% and as poor/very poor by 58.2%. Most physicians (90%) reported asking and recording smoking status, 89% advised patients to quit smoking but only 37% asked them to set a quit date and 44% prescribed medications. Multivariate analyses showed that Physicians’ perceived quality of their training in smoking cessation methods was associated with greater use of evidence-based cessation interventions. (OR = 6.5; 95% CI = 2.2–19.1); motivating patients to quit (OR: 7.9 CI 3.44–18.5), assisting patients to quit (OR = 9.9; 95% CI = 4.0–24.2) prescribing medications (OR = 9.6; 95% CI = 3.5–26.7), and setting up follow-up (OR = 13.0; 95% CI = 4.4–38.5). Conclusions Perceived quality of training in smoking cessation was associated with using evidence-based interventions and among physicians from Argentina. Medical training programs should enhance the quality of this curriculum. PMID:27594922

    Bovine brucellosis is a zoonotic disease spread worldwide. The infection in cattle is predominantly caused by Brucella abortus and is usually detected in pregnant females through abortions. The disease is endemic in Argentina; however, infection in humans is underestimated and often not reported. The prevalence of bovine brucellosis in countries bordering Argentina is quite variable: 0.04% in Uruguay, 10.20% in the north and 0.06% in the south of Brazil, 0.2% in Chile, 3.15% in Paraguay and 2.27% in Bolivia. In 1999, the Argentine National Control and Eradication Program was implemented. Its strategies include identification of vaccinated animals, compulsory vaccination with B. abortus S19 of 100% of 3- to 8-month-old females, negative serological tests before animal movements and categorization of farms in terms of their brucellosis status. The epidemiological surveillance in milk is performed through the milk ring test and the indirect ELISA. The result of a national brucellosis survey performed in 2004 indicates that 12.4% (95% CI: 10.89-14.0) of Argentine beef farms are seropositive to Brucella and that the apparent prevalence in cattle is 2.10% (95% CI: 1.90-2.40). The official serological diagnostic tests are as follows: buffered plate antigen test, as screening, serum agglutination test, 2-mercaptoethanol and fluorescence polarization assay, competitive ELISA, as confirmatory tests, and complement fixation test, as definitive test. Santa Fe and a district in Córdoba have 'Outstanding Plans'. Tierra del Fuego is a 'Zone free from bovine brucellosis'. One question arising when studying the Argentine situation is why the disease remains endemic if good regulations exist to control and eradicate it. In future, some different aspects might be evaluated to understand it, and further studies should be performed to prioritize, select and refine control strategies. © 2012 Blackwell Verlag GmbH.

  1. Radiation budget changes with dry forest clearing in temperate Argentina.

    2013-04-01

    Land cover changes may affect climate and the energy balance of the Earth through their influence on the greenhouse gas composition of the atmosphere (biogeochemical effects) but also through shifts in the physical properties of the land surface (biophysical effects). We explored how the radiation budget changes following the replacement of temperate dry forests by crops in central semiarid Argentina and quantified the biophysical radiative forcing of this transformation. For this purpose, we computed the albedo and surface temperature for a 7-year period (2003-2009) from MODIS imagery at 70 paired sites occupied by native forests and crops and calculated the radiation budget at the tropopause and surface levels using a columnar radiation model parameterized with satellite data. Mean annual black-sky albedo and diurnal surface temperature were 50% and 2.5 °C higher in croplands than in dry forests. These contrasts increased the outgoing shortwave energy flux at the top of the atmosphere in croplands by a quarter (58.4 vs. 45.9 W m(-2) ) which, together with a slight increase in the outgoing longwave flux, yielded a net cooling of -14 W m(-2) . This biophysical cooling effect would be equivalent to a reduction in atmospheric CO2 of 22 Mg C ha(-1) , which involves approximately a quarter to a half of the typical carbon emissions that accompany deforestation in these ecosystems. We showed that the replacement of dry forests by crops in central Argentina has strong biophysical effects on the energy budget which could counterbalance the biogeochemical effects of deforestation. Underestimating or ignoring these biophysical consequences of land-use changes on climate will certainly curtail the effectiveness of many warming mitigation actions, particularly in semiarid regions where high radiation load and smaller active carbon pools would increase the relative importance of biophysical forcing. © 2012 Blackwell Publishing Ltd.

    Hepatitis B virus (HBV) infection is a major public health problem worldwide. The aims of this study were to describe the molecular epidemiology of HBV in the Province of Misiones, Argentina and estimate the phylodynamic of the main groups in a Bayesian coalescent framework. To this end, partial or complete genome sequences were obtained from 52 blood donor candidates. The phylogenetic analysis based on partial sequences of S/P region showed a predominance of genotype D (65.4%), followed by genotype F (30.8%) and genotype A as a minority (3.8%). At subgenotype level, the circulation of subgenotypes D3 (42.3%), D2 (13.5%), F1b (11.5%) and F4 (9.6%) was mainly identified. The Bayesian coalescent analysis of 29 complete genome sequences for the main groups revealed that the subgenotypes D2 and D3 had several introductions to the region, with ancestors dating back from 1921 to 1969 and diversification events until the late '70s. The genotype F in Misiones has a more recent history; subgenotype F4 isolates were intermixed with sequences from Argentina and neighboring countries and only one significant cluster dated back in 1994 was observed. Subgenotype F1b isolates exhibited low genetic distance and formed a closely related monophyletic cluster, suggesting a very recent introduction. In conclusion, the phylogenetic and coalescent analyses showed that the European genotype D has a higher circulation, a longer history of diversification and may be responsible for the largest proportion of chronic HBV infections in the Province of Misiones. Genotype F, especially subgenotype F1b, had a more recent introduction and its diversification in the last 20years might be related to its involvement in new transmission events.

    The aim of the present study is to describe the general characteristics of a cohort of patients with early arthritis in Argentina. CONAART (Consorcio Argentino de Artritis Temprana--Argentine Consortium for Early Arthritis) is an initiative of seven rheumatology centres across Argentina. Patients were included if they had at least one or more swollen joints and <2 years of disease duration. Social, demographic, familiar, hereditary, clinical and laboratory data were recollected. At first visit and every year, X-rays of hands and feet were performed and working characteristics and pharmaco-economic data were re-collected. A total of 413 patients were included. Of them, 327 (79.2%) were women with a median age of 49 years and a median disease duration of 6 months. Of the total, 183 (44.3%) had RA (ACR 1987) and 167 (40.4%) undifferentiated arthritis (UA). Other diagnoses included: 12 crystalics, 11 PsA, 6 uSpA, 6 other CTD, 1 AS and 27 other diagnosis. As 85% of our population had RA and UA, we only compared these two groups of patients. Patients with RA had significantly worse activity parameters of the disease (DAS of 28 joints), functional capacity (HAQ) and quality of life (Rheumatoid Arthritis Quality of Life) than patients with UA. The frequency of RF and anti-CCP, and symmetrical distribution were also significantly higher in patients with RA compared with UA patients. All patients with RA initiated early specific treatment, in a period no longer than 6 months from the beginning of the disease. Early arthritis clinics are a useful tool to identify and treat patients with different forms of joint involvement.

    Objective To describe the strategies pursued by the tobacco industry (TI) to interfere with the ratification of the WHO Framework Convention on Tobacco Control (FCTC) in Argentina. Methods We conducted semi-structured interviews about the FCTC, the TI and the legislative process with 3 legislators, 4 public health officials, 1 representative of the tobacco growers and two tobacco-control advocates. We reviewed 6 newspapers from the 4 tobacco growing provinces, searched TI documents in the Legacy Tobacco Documents Library and reviewed 1624 documents. Proposed legislation and related documents on tobacco control from Argentina’s National Congress and the Provincial Jujuy Congress were reviewed. Results The principal strategy used by the TI was lobbying of provincial legislators and federal officials from the Ministry of the Economy by the tobacco growers associations. These legislators prevented the passage of comprehensive bills on tobacco control or of less comprehensive national laws. A typical legislative strategy used was to request additional analyses of the proposed bills from committees that prioritized economic issues over health. FCTC was mentioned in regional newspapers three to seven times per week in articles about alleged adverse economic effects of tobacco control. Direct physical threats to legislators who were openly supportive of FCTC ratification were made. Conclusion Tobacco producers and TI opposed FCTC ratification in Argentina by lobbying elected representatives and placing stories in regional media to obstruct approval of tobacco control laws. These activities have led to a delay in consideration of Argentina’s ratification of the FCTC despite the President’s signature in 2003. (250 words) PMID:19956349

    Sarcocystis spp. are protozoan parasites with a heteroxenous life cycle, which produce cysts in the muscle of herbivorous animals. In these animal species, sarcocystosis is frequently asymptomatic, although it may occur with high prevalence. Seven Sarcocystis spp. have been described in red deer (Cervus elephus). The aim of this study was to determine the prevalence of sarcocystosis, and to perform the morphological and molecular characterization of Sarcocystis spp. found in wild red deer of the Nahuel Huapi National Park (NHNP), Patagonia, Argentina. Full necropsies of 62 red deer killed by hunters in the NHNP and neighboring areas were performed. Samples of heart and skeletal muscle were examined histologically and selected samples were also examined by transmission electron microscopy (TEM), PCR and sequencing. Sarcocystis spp. thin walled cysts were detected in 62 % (38/62) of heart, and in 22 % (3/14) of skeletal muscle samples examined histologically. TEM revealed a smooth and thin cyst wall (≤1 μm), with scarce and separated ribbon-like protrusions. A total of three partial and one full 18S ribosomal RNA (rRNA) gene sequences were obtained, and showed the highest identity (≥99 %) with Sarcocystis taeniata, a species described in moose (Alces alces). The morphological and molecular results indicate that red deer in Argentina are frequently infected with S. taeniata, a species for which the definitive host is unknown. The present results also confirm that Sarcocystis spp. using cervids as intermediate host are not host-specific. Further studies are needed to improve the epidemiological knowledge of Sarcocystosis in red deer.

    The research presented in this paper analyses the clinic-pathological manifestations and work-related health risks identified among outpatients treated in the hospitals of Rome and Buenos Aires. The occupational anamnestic data were collected between 2013 and 2014 through questionnaires with specific items aimed at detecting occupational diseases classified by target organ systems in outpatient clinics of cardiology, dermatology, physical medicine, ophthalmology, orthopedics, endocrinology (thyroid and gonads). An inferential statistical analysis was then carried out to evaluate the relationship between nationality, exposure to occupational risks and the prevalence and incidence of the selected pathologies. An univariate statistical analysis was performed for this purpose and, in the case of statistically significant results, a subsequent multivariate analysis was used to evaluate the incidence of occupational risk factors and nationality on the pathology diagnosed in conjunction with other confounding factors such as smoking habits and gender. The total sample consisted of 1090 subjects of both sexes. Risks were grouped into seven categories and diseases into 12 diagnostic groups. We analyzed the correlation between risks and diseases with respect to hospital outpatients and to the total sample then comparing Argentina and Italy's data. Analysis of data revealed a higher prevalence of hypertension and dysmetabolic disorders for DSE (Display Screen Equipment) workers both in Italy and Argentina; however, multivariate analysis showed that smoking represents a confounding factor for this association. A higher prevalence of allergic contact dermatitis (ACD) was found in the population samples of Rome and there appeared to be a correlation between eye disorders/defects and Argentine data source. Our study suggests the usefulness of collecting occupational anamnestic data from outpatient departments to highlight possible associations between occupational risks

    Amoco Argentina oil Company secured a farm-in from YPF (50-50 partnership) over the blocks CN-VIII and ON-IX in the Neuquen basin of Argentina. Primary reservoir horizons are Late Jurassic and Early Cretaceous eolian sands. The petrophysical properties of these dunal sands contrast-sometimes sharply-with those of the silts and shales of similar age in the immediate area. Initial evaluation of the blocks had recognized stratigraphic potential associated with the dunal facies, especially in the CN-VIII block. The presence of reservoir quality Avile sands (Barremian age, 18-20% porosity) was mapped on the CN-VIII block directly from older vintage seismic. (1) Seismic Acquisition: Amoco shot approximately 400 km of high resolution 120-fold seismic in late 1994 to high-grade those leads identified on the old seismic. The CN-VIII block is partially covered by basalts of varying thickness. The Amoco survey resulted in an improved penetration through the basalts; it also had a much higher frequency content and yielded superior bed resolution than any previous survey in the area. (2) Seismic Processing and Modeling: Amoco reprocessed inhouse several key lines over producing fields in the immediate area and approximately 200 km of seismic from the 1994 survey in the CN-VIll block for detailed amplitude analysis. Seismic amplitude models [including (1) 2-D stratigraphic pinchout models describing the presence of porous sand lenses, and (2) AVO models] tie the 1994 data very well. (3) Integrated Seismic Interpretation and Reduction of Technical RISK: The integration of various disciplines (Petrophysics, Geophysics, Geology, and Engineering) resulted in the calibration/ranking of seismic responses observed over the CN-VIII area, thus substantially reducing the RISK on trap definition, reservoir quality, seal, and product associated with the early leads.

    To describe the medical genetics services in Argentina, in order to help organize a network to coordinate those services, decrease inequity in access to them, and promote the comprehensive development of medical genetics in the country. In April-August 2004 a survey was conducted of centers providing medical genetics services in Argentina, looking at their human resources, diagnostic procedures, the services that patients use, and funding. The survey covered service centers that conduct genetic assessment, cytogenetic diagnostic testing, molecular biology testing, and biochemical testing to detect birth defects or genetic disorders. Centers that were devoted exclusively to research were not surveyed. A total of 134 centers fulfilled the selection criteria for the survey; 84 of them were private services, and the other 50 were publicly managed services, at universities and hospitals. The 50 public facilities had a total of 67 physicians who had studied clinical genetics, plus 133 non-medical laboratory professionals. A majority of the 50 centers performed clinical and cytogenetic diagnoses, with a smaller number performing molecular, biochemical, and prenatal diagnoses. More than 70% of the centers and human resources were located in an area that includes the city of Buenos Aires, the province of Buenos Aires, and the nearby north-central provinces of Córdoba and Santa Fe. The 50 public centers were found mainly in large cities; 10 of the country's 23 provinces had no public services. There is a great geographic disparity in the availability of resources as well as wide variability in the diagnostic procedures that are provided in the different service centers. The unequal distribution of the facilities is an organizational problem that will require the application of policies to guarantee minimum services for people in all regions of the country, as well as access to more complex diagnostic procedures.

    Objective To estimate the long-term and short-term effects on cigarette demand in Argentina based on changes in cigarette price and income per person >14 years old. Method Public data from the Ministry of Economics and Production were analysed based on monthly time series data between 1994 and 2010. The econometric analysis used cigarette consumption per person >14 years of age as the dependent variable and the real income per person >14 years old and the real average price of cigarettes as independent variables. Empirical analyses were done to verify the order of integration of the variables, to test for cointegration to capture the long-term effects and to capture the short-term dynamics of the variables. Results The demand for cigarettes in Argentina was affected by changes in real income and the real average price of cigarettes. The long-term income elasticity was equal to 0.43, while the own-price elasticity was equal to −0.31, indicating a 10% increase in the growth of real income led to an increase in cigarette consumption of 4.3% and a 10% increase in the price produced a fall of 3.1% in cigarette consumption. The vector error correction model estimated that the short-term income elasticity was 0.25 and the short-term own-price elasticity of cigarette demand was −0.15. A simulation exercise showed that increasing the price of cigarettes by 110% would maximise revenues and result in a potentially large decrease in total cigarette consumption. Conclusion Econometric analyses of cigarette consumption and their relationship with cigarette price and income can provide valuable information for developing cigarette price policy. PMID:23760657

  11. A new pitheciin primate from the middle Miocene of Argentina.

    We report here a new fossil primate from the middle Miocene of Argentina. The material consists of isolated teeth, mandibular fragments, and a talus. The fossils were collected in the Collón Cura formation at Cañadón del Tordillo in Neuquén Province. An age of 15.71 +/- 0.07 Ma has been reported for the Pilcaniyeu Ignimbrite, which lies just below the paleosols in which the fossils were found. This material is thus the youngest occurrence of fossil primates in Argentina (hitherto documented in the Santacrucian and older land mammal ages) but still is older than the middle Miocene platyrrhine primates from La Venta, Colombia, in particular the pitheciins Nuciruptor and Cebupithecia. The material is recognized as a new genus and species of Pitheciinae, Propithecia neuquenensis. The mesiodistally compressed, high-crowned incisors are specialized and similar to species in the tribe Pithecini and to the nonpitheciin Soriacebus (early Miocene, Patagonia). We rule out a phylogenetic relationship to the latter because of differences in molar morphology. Propithecia does, however, fit well into the pattern of pitheciin evolution, being more derived than the middle Miocene pitheciin Nuciruptor but not as much as another middle Miocene taxon, Cebupithecia. As such, this makes Propithecia the oldest taxon that can be confidently placed within this modern New World monkey subfamily. By analogy with the molar structures and diets of extant platyrrhines, Propithecia has a molar structure consistent with a variety of low-fiber diets ranging from fruit and gum to seeds. Its incisors suggest seed-eating in much the same way as extant pitheciins, like Pithecia. The talus resembles that of Callicebus, suggesting arboreal quadrupedal locomotion.

    Biological control of gastrointestinal nematodes of ruminants by use of nematophagous fungi would become part of any livestock parasite integral control system. Identifying autochthonous species that could then be selected for mass production is an important phase in the practical use of biological control. To search for nematophagous fungi with potential use as biological control agents against gastrointestinal nematodes in Argentina. Decomposing cattle faeces sampled in different locations were incubated in water agar 2% with Panagrellus sp. The developed nematophagous fungi were transferred to new water agar 2% plates and then to corn meal agar plates in order to carry out their identification. Fungal diversity and richness were also assessed. Seventeen species from nine genera of nematophagous fungi were found. Twelve species were nematode-trapping fungi and three species plus two fungi identified to genus level corresponded to endoparasitic fungi. Arthrobotrys conoides, Arthrobotrys oligospora, Duddingtonia flagrans, Monacrosporium doedycoides, Arthrobotrys robusta and Drechmeria coniospora were the most frequently isolated species overall in the whole study (6.6%, 5.7%, 5.7%, 5.7%, 4.7% and 4.7%, respectively) although other species were more frequently recorded at local levels such as Arthrobotrys pyriformis (18.8%). Only A. conoides has been previously isolated from ruminant faecal samples in Argentina. Five nematode-trapping fungal species are mentioned for the first time in the Americas D. flagrans and A. conoides, both identified in the present study, are among the most promising ones as biological control agents against gastrointestinal nematodes of ruminants.

    The number of graduate programs in Optoelectronics in Argentina is scarce. The current Optics and Photonics Education Directory lists only three programs. One of them was launched in 2001 in the Facultad de Ingeniería (College of Engineering), Universidad de Buenos Aires (UBA). This was the first graduate program in the field, leading to a Master Degree in Optoelectronics. This decision arose from the demand of telecommunications industries and several estate- or private-funded research institutions working with us in the fields of lasers, optics, remote sensing, etc. A great bonus was the steady work, during several decades, of research groups in the College on the development of different type of lasers and optical non destructive tests and their engineering applications. As happened in many engineering graduate programs in Argentina at that time, few non full-time students could finish their studies, which called for 800 hours of traditional lecture-recitation classes, and the Master Thesis. In recent years Argentine Education authorities downsized the Master programs to 700 hours of blended learning and we redesigned the Graduate Optoelectronic Engineering Program to meet the challenge, dividing it in two successive one year programs, the first aimed at a professional training for almost immediate insertion in the labor market (called Especialización en Ingeniería Optoelectrónica), and the second (called Maestría en Ingeniería Optoelectrónica y Fotónica) aimed at a more academic and research target to comply with the UBA standards for Master degrees. The present work is a presentation of the new program design, which has begun in the current year.

    The last decades of the xix century were years of resurgence and progress in the field of Naval Health, which was in the vanguard of European health structures at that time. In this era, the navy physicians produced some documents known as "Memorias Clínicas" (Clinical Reports), previously established as obligatory in their rules and regulations. Valuable documents on medical science and the art of healing are deposited in the Archivo General de la Marina (Viso del Marqués, Ciudad Real). Although the information recorded in these Reports varies considerably, we have centred our interest on those that focus on the discovery and development of anaesthesia. The introduction of these discoveries was surrounded by immense controversy, with its defenders and critics. The exclusiveness of the documents presented here is an original testimony to the medical-surgical knowledge of the era and places Naval Health in the vanguard of European health structures at that time.

    Iron spectra have been recorded from plasmas created at three different laser plasma facilities, the Tor Vergata University laser in Rome (Italy), the Hercules laser at ENEA in Frascati (Italy), and the Compact Multipulse Terawatt (COMET) laser at LLNL in California (USA). The measurements provide a means of identifying dielectronic satellite lines from FeXVI and FeXV in the vicinity of the strong 2p {yields} 3d transitions of FeXVII. About 80 {Delta}n {ge} 1 lines of FeXV (Mg-like) to FeXIX (O-like) were recorded between 13.8 to 17.1 {angstrom} with a high spectral resolution ({lambda}/{Delta}{lambda} {approx} 4000), about thirty of these lines are from FeXVI and FeXV. The laser produced plasmas had electron temperatures between 100 to 500 eV and electron densities between 10{sup 20} to 10{sup 22} cm{sup -3}. The Hebrew University Lawrence Livermore Atomic Code (HULLAC) was used to calculate the atomic structure and atomic rates for FeXV to FeXIX. HULLAC was used to calculate synthetic line intensities at T{sub e} = 200 eV and n{sub e} = 10{sup 21}cm{sup -3} for three different conditions to illustrate the role of opacity: optically thin plasmas with no excitation-autoionization/dielectronic recombination (EA/DR) contributions to the line intensities, optically thin plasmas that included EA/DR contributions to the line intensities, and optically thick plasmas (optical depth {approx} 200 {micro}m) that included EA/DR contributions to the line intensities. The optically thick simulation best reproduced the recorded spectrum from the Hercules laser. However some discrepancies between the modeling and the recorded spectra remain.

    Due to the importance of the winemaking sector in Mendoza, Argentina, the assessment of future scenarios for viticulture is of foremost relevance. In this context, it is important to understand how temperature increase and precipitation changes will impact on grapes, because of changes in grapevine phenology and suitability wine-growing regions must be understood as an indicator of climate change. The general objective is to classify the suitable areas of viticulture in Argentina for the current and future climate using the MM5 regional climate change simulations. The spatial distribution of annual mean temperature, annual rainfall, and some bioclimatic indices has been analyzed for the present (1970-1989) and future (2080-2099) climate under SRES A2 emission scenario. In general, according to projected average growing season temperature and Winkler index classification, the regional model estimates (i) a reduction of cool areas, (ii) a westward and southward displacement of intermediate and warm suitability areas, and (iii) the arise of new suitability regions (hot and very hot areas) over Argentina. In addition, an increase of annual accumulated precipitation is projected over the center-west of Argentina. Similar pattern of change is modeled for growing season, but with lower intensity. Furthermore, the evaluation of projected seasonal precipitation shows a little precipitation increase over Cuyo and center of Argentina in summer and a little precipitation decrease over Cuyo and northern Patagonia in winter. Results show that Argentina has a great potential for expansion into new suitable vineyard areas by the end of twenty-first century, particularly due to projected displacement to higher latitudes for most present suitability winegrowing regions. Even though main conclusions are based on one global-regional model downscaling, this approach provides valuable information for implementing proper and diverse adaptation measures in the Argentinean viticultural

    The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a cryptic species complex that contains some of the most damaging pests in tropical and subtropical regions. Recent studies suggested that this complex is composed of at least 24 distinct species. We use the approach from these studies to consider the identity of B. tabaci in Argentina. Previous studies have suggested the presence of a B. tabaci presumably indigenous to the Americas and referred to as the BR biotype in Argentina. We placed the entity referred to as the BR biotype within the B. tabaci cryptic species complex using whiteflies collected in soybean and bean crops in northern and central Argentina. The whiteflies were assigned using the mitochondrial cytochrome oxidase (mtCOI) gene. Four unknown haplotypes plus two Argentina sequences from GenBank formed a cluster that was basal to the rest of the New World sequences. These sequences diverged from the consensus sequence across the range of 3.6 to 4.3%. Applying the species assignment rules of recent studies suggests that the individuals from Argentina form a separate species. A fifth unknown haplotype fell within the New World putative species and formed a distinct cluster with haplotypes from Panama. These results suggest that Argentina has two indigenous species belonging to the B. tabaci cryptic species complex. Rather than using mtCOI sequencing for all B. tabaci collected, a simple random amplified polymorphic DNA-polymerase chain reaction diagnostic was used and tested along with previously published primers designed to work specifically with the BR biotype from Brazil. These primers were either unable to distinguish between the two indigenous members of the complex in Argentina or indicated a difference when none was evident on the basis of mtCOI sequence comparison.
