    2016-01-01

    U ovom je radu opisana ranjivost obala otoka Raba koja može biti prouzročena prognoziranim porastom razine mora do kraja 21. stoljeća. Opisane su posljedice koju taj prirodni fenomen može prouzročiti. Analizirana su tri scenarija pojava visoke razine mora: kod stagnacije globalne morske razine te kod porasta za 30 i 60 cm. Analize su napravljene na topografskim kartama mjerila 1:5000. Ustanovljene su najugroženije urbanizirane obalne zone: uvala Sv. Eufemija, luka grada Raba, Supetarska Draga...

    Full Text Available Procjene za prosječan porast morske razine na globalnoj razini do kraja 21. stoljeća najčešće variraju od 0,18 m do ≥ 1 m u odnosu na današnju razinu. Ako se razmatraju procjene koje obuhvaćaju i otapanje grenlandskog i antarktičkog ledenog pokrova, tada se može očekivati porast morske razine od 5 i više m. Sukladno s globalnim promjenama, razina Jadranskog mora također je u porastu. Radi analize potencijalne ugroženosti hrvatske obale od porasta morske razine, izrađena su tri modela porasta razine Jadranskog mora (od 1 m, 3 m i 6 m. Na temelju modela analizira se utjecaj porasta morske razine na različite socioekonomske segmente obalnog prostora. Cilj je istraživanja definirati najugroženije dijelove hrvatske obale. Kako bi se mogli diferencirati najugroženiji dijelovi, izrađen je Indeks ugroženosti obalnih općina ( . U izradi Indeksa koristili su se analizom utjecaja dobiveni kvantitativni podaci o prostornom obuhvatu poplavnih zona te ugroženosti stanovništva i prometne infrastrukture obalne zone. Navedenim su varijablama s pomoću Analitičkog hijerarhijskog procesa (AHP pridruženi različiti težinski koeficijenti, ovisno o važnosti varijable. Pri analizi svih triju modela uočeno je kako se Zadar i njegova okolica ističu kao najugroženije područje hrvatske obale. Zbog toga je na primjeru Zadra izvršena znatno detaljnija analiza mikrolokacijskog utjecaja porasta morske razine. Podaci dobiveni analizom različitih modela pokazuju kako je gotovo cijela hrvatska obala ugrožena, ali i da postoji velik nerazmjer u razini ugroženosti pojedinih dijelova hrvatske obale. Važnost je ovog istraživanja u tome što ono predstavlja temelj za pravovremenu adaptaciju na negativne utjecaje budućeg porasta razine Jadranskog mora.

    Introgression of the callipyge (CLPG) mutation into the fat-tail Assaf breed was initiated by inseminating Assaf ewes with Dorset-Hampshire semen from a ram that was heterozygous for the callipyge mutation. Presence of the mutation in the F1 generation and the first backcross generation (BC1) was validated using molecular markers linked to the CLPG locus. Carcasses of callipyge BC1-CN lambs had significantly (P less than 0.01) better conformation than carcasses of normal BC1-NN lambs and straightbred Assaf lambs. Computerized tomography analysis of live BC1 and Assaf lambs showed that carrying the callipyge mutation increased Longissimus dorsi and Quadriceps femoris muscles by about 30

    Suckling lamb meat is traditionally produced in Mediterranean Europe. Breed can affect the quality of the lamb carcass and meat. This study is aimed at comparing the carcass and meat quality between suckling lambs from a local and a non-native dairy breed, Churra and Assaf. Churra is included in the Spanish Protected Geographical Indication (PGI) 'Lechazo de Castilla y León', whereas Assaf is not. However, Assaf breeders have requested the inclusion of the breed in the PGI. Carcasses and meat from 16 male lambs (eight Churra and eight Assaf) were used in this study. The lambs were all raised under an intensive rearing system and fed on a milk substitute to minimise maternal influence. The carcasses were evaluated for conformation, fatness, joint and leg tissue proportions and the meat was analysed for composition (i.e. proximate composition, iron, haematin, fatty acids and volatiles) and technological quality traits (i.e. texture, water holding capacity, colour and lipid stability). Churra carcasses were larger than Assaf carcasses. However, the proportions of commercial joints and main tissues did not differ between breeds. Cavity and intermuscular leg fat, but not total leg fat, were higher in Churra carcasses. Churra meat showed a higher proportion of n-6 fatty acids, higher redness and better colour stability during aerobic storage. In contrast, Assaf lamb was more resistant to lipid oxidation after cooking. This is a preliminary study to measure the influence of breed on a wide range of quality characteristics in Churra and Assaf suckling lamb carcass and meat. It may be of relevance for breeders, consumers and food policy makers, setting the basis for future studies that include larger commercial populations.

    Estoy maravillado con el monumental esfuerzo y trabajo de Efraim Otero-Ruiz en la producción de su portentoso libro “Setenta años del cáncer en Colombia”.

    Escrito en una prosa amena y armoniosa, su lectura es verdadero deleite intelectual para quien sigue la apasionante madeja que constituye toda la trama inicial y que envuelve la concepción, el nacimiento y el desarrollo de una institución para el tratamiento del cáncer en Colombia.

    Es apasionante la forma como Efraim toma el hilo de la historia desde sus primeras y más importantes incepciones.

    Es sin duda Claudio Regaud, Jefe del Laboratorio de Radiofisiología del Instituto de Radium de París, la figura clave en la iniciativa de creación de un Instituto de Radium en Colombia. Alfonso Esguerra Gómez, becario de la Institución adquiere una valiosa experiencia en el tratamiento de tumores superficiales de cara y cuello y descubre la famosa pasta Colombia que permite amoldarse sobre la piel mientras en su interior se colocan las agujas de radium.

    En la década de los veinte Regaud se convierte en la figura más prestante en el mundo en el manejo del radium y es invitado universalmente para comunicar no solo sus experiencias sino como consejero y orientador de la creación de institutos de radium en el mundo.

    La invitación a Regaud en 1928 para visitar el Perú es conocida por Alfonso Esguerra y allí por primera vez se organiza un movimiento de influencias que con agudo análisis describe Efraim Otero, para movilizar todas las fuerzas académicas y políticas con el fin de aprovechar esta oportunidad y obtener la visita de Regaud a Colombia.

    En varias ocasiones en el futuro, circunstancias similares harán necesaria la influencia de médicos, no solo eminentes sino dotados de excelentes conexiones sociales y políticas para crear el Instituto Nacional de Radium.

    Twenty dairy sheep farms of Assaf breed, located in the Spanish autonomous community of Castilla y León and included in a group receiving technical support, were used to study their production cost structure and to assess their economic profitability during 2009. On average, farms had 89.2±38.0 ha (own, 38%), 592±63 ewes, yielded 185.9±21.1×10(3) L/yr (i.e., 316±15 L/ewe), and were attended by 2.3±0.2 annual working units (family, 72%). Total annual income was €194.4±23.0×10(3)/yr (€1.0=$1.3) from milk (78.6%), lamb (13.2%), culled ewes (0.5%), and other sales (0.8%, wool and manure), and completed with the European Union sheep subsidy (6.9%). Total costs were €185.9±19.0×10(3)/yr to attend to feeding (61.6%), labor (18.2%), equipment maintenance and depreciation (7.6%), finances (3.0%), animal health (2.5%), energy, water and milking supplies (2.2%), milk recording (0.5%), and other costs (4.4%; assurances, shearing, association fees, and so on). Mean dairy sheep farm profit was €8.5±5.8×10(3)/yr (€7.4±8.3/ewe) on average, and varied between -€40.6 and €81.1/ewe among farms. Only 60% of farms were able to pay all costs, the rest had negative balances. Nevertheless, net margin was €31.0±6.5×10(3)/yr on average, varying between €0.6 and €108.4×10(3)/yr among farms. In this case, without including the opportunity costs, all farms had positive balances. Total annual cost (TAC; €/ewe) and total annual income (TAI; €/ewe) depended on milk yield (MY; L/ewe) and were TAC=161.6 + 0.502 MY (R(2)=0.50), and TAI=78.13 + 0.790 MY (R(2)=0.88), respectively, with the break-even point being 291 L/ewe. Conversely, farm TAC (€/yr) and farm TAI (€/yr) were also predicted as a function of the number of ewes (NOE) per flock, as TAC=18,401 + 282.8 NOE (R(2)=0.89) and TAI=330.9 NOE (R(2)=0.98), with the break-even point being 383 ewes/flock. Finally, according to the increasing trend expected for agricultural commodity prices, it was

  15. A submissão do indivíduo ao projeto nacional israelense nos contos de Izhar Smilansky

    Directory of Open Access Journals (Sweden)

    Gabriel Steinberg

    2012-03-01

    Full Text Available Izhar Smilansky, nascido à época do início da colonização judaica na Terra de Israel, é um dos mais destacados escritores da chamada “Geração da Guerra da Independência”, educados e moldados numa cultura hebraica que valorizava o trabalho agrícola, a justiça social e a ética. Izhar Smilansky, ou mais conhecido como S. Izhar, inaugura as obras literárias dessa geração de escritores ao publicar em 1938 o conto Efraim volta para a Alfafa, um exemplo de abnegação e renúncia, no qual Efraim mesmo querendo ter uma trajetória própria se dobra diante da ideologia da época. Izhar prossegue nessa trajetória com a publicação em maio de 1949 do conto “Caravana da meia-noite”, em que em plena Guerra da Independência e com as incertezas em relação ao futuro, ele faz uma exaltação fervorosa dos jovens que estavam dispostos a dar a própria vida pela redenção territorial de um povo.

  16. Foreign Reports about Stepan Razin’s Execution. New Documents from the Stockholm Archive

    Directory of Open Access Journals (Sweden)

    Gleb M. Kazakov

    2017-12-01

    Full Text Available This paper analyzes reports written by foreign authors about the execution of Stepan Razin. The main focus is on two dispatches written by the Swedish citizen and merchant in Moscow, Christoff Koch, in May–June 1671 and sent to Narva, and from there, they were forwarded to the Swedish capital, among other places. They are now kept at the State Archives in Stockholm, and they have not been discussed previously in the scholarly literature. The paper contains the full translation into Russian of two long reports written by Koch about Razin’s capture, delivery to Moscow, interrogation, and execution, with our comments. Special attention is given to a unique colored drawing, showing the brothers, Stepan and Frol Razin, as well as the body parts of the executed Stepan. From the written documents it becomes clear that the drawing was sent from Moscow to the governor of Swedish Ingria in Narva, and then forwarded to Stockholm, together with the two Koch dispatches. The authors come to the conclusion that several copies must have been made and that they were intentionally distributed among foreigners in Moscow. Most probably only one copy has survived to our days, the one in Stockholm. Arguments are given for the hypothesis that one copy of the drawing ended up in England and served as the prototype for the well-known imprint of 1672, which shows the Razin brothers when they were being delivered to Moscow. In our study we also compare the information given by Koch with descriptions of Razin’s death that were published in West-European newspapers, pamphlets, and books during the 1670s. This comparison brings us to the conclusion that the information about the execution of the leader of the rebellion reached the European press from several witnesses to the events, and that, over time, the original information was filled out with invented details.

    IL-33 polymorphisms influence the susceptibility to asthma. IL-33 indirectly induces Th2-immune responses via dendritic cell activation, being important for development of atopic diseases. Furthermore, IL-33 upregulates regulatory T cells (Tregs), which are critical for healthy immune homeostasis. This study investigates associations between IL-33 polymorphisms during the development of childhood atopic diseases and underlying mechanisms including immune regulation of Tregs. Genotyping of IL-33-polymorphisms (rs928413, rs1342326) was performed by MALDI-TOF-MS in 880 of 1133 PASTURE/EFRAIM children. In 4.5-year-old German PASTURE/EFRAIM children (n = 99), CD4 + CD25 high FOXP3 + Tregs were assessed by flow cytometry following 24-h incubation of PBMCs with PMA/ionomycin, LPS or without stimuli (U). SOCS3, IL1RL1, TLR4 mRNA expression and sST2 protein levels ex vivo were measured in PASTURE/EFRAIM children by real-time PCR or ELISA, respectively. Health outcomes (hay fever, asthma) were assessed by questionnaires at the age of 6 years. rs928413 and rs1342326 were positively associated with hay fever (OR = 1.77, 95%CI = 1.02-3.08; OR = 1.79, 95%CI = 1.04-3.11) and CD4 + CD25 high FOXP3 + Tregs (%) decreased in minor allele homozygotes/heterozygotes compared to major allele homozygotes (p(U) = 0.004; p(LPS) = 0.005; p(U) = 0.001; p(LPS) = 0.012). SOCS3 mRNA expression increased in minor allele homozygotes and heterozygotes compared with major allele homozygotes for both IL-33-polymorphisms (p(rs928413) = 0.032, p(rs1342326) = 0.019) and negatively correlated to Tregs. IL-33-polymorphisms rs928413 and rs1342326 may account for an increased risk of hay fever with the age of 6 years. Lower Tregs and increased SOCS3 in combined heterozygotes and minor allele homozygotes may be relevant for hay fever development, pointing towards dysbalanced immune regulation and insufficient control of allergic inflammation. © 2016 John Wiley & Sons A/S.

    The pandemic of carbapenem-resistant Enterobacteriaceae (CRE) was primarily due to clonal spread of bla KPC producing Klebsiella pneumoniae. Thus, thoroughly studied CRE cohorts have consisted mostly of K. pneumoniae. To conduct an extensive epidemiologic analysis of carbapenem-resistant Enterobacter spp. (CREn) from 2 endemic and geographically distinct centers. CREn were investigated at an Israeli center (Assaf Harofeh Medical Center, January 2007 to July 2012) and at a US center (Detroit Medical Center, September 2008 to September 2009). bla KPC genes were queried by polymerase chain reaction. Repetitive extragenic palindromic polymerase chain reaction and pulsed-field gel electrophoresis were used to determine genetic relatedness. In this analysis, 68 unique patients with CREn were enrolled. Sixteen isolates (24%) were from wounds, and 33 (48%) represented colonization only. All isolates exhibited a positive Modified Hodge Test, but only 93% (27 of 29) contained bla KPC. Forty-three isolates (63%) were from elderly adults, and 5 (7.4%) were from neonates. Twenty-seven patients died in hospital (40.3% of infected patients). Enterobacter strains consisted of 4 separate clones from Assaf Harofeh Medical Center and of 4 distinct clones from Detroit Medical Center. In this study conducted at 2 distinct CRE endemic regions, there were unique epidemiologic features to CREn: (i) polyclonality, (ii) neonates accounting for more than 7% of cohort, and (iii) high rate of colonization (almost one-half of all cases represented colonization). Since false-positive Modified Hodge Tests in Enterobacter spp. are common, close monitoring of carbapenem resistance mechanisms (particularly carbapenemase production) among Enterobacter spp. is important.

    Research highlights: → Adsorption behaviour of shallow oxidized sediments from Matlab Region in SE Bangladesh is investigated. → Oxidized sediments have a high capacity to adsorb arsenic. → Adsorption capacity will be reduced by high concentration of reactive organic C. → Monitoring of groundwater quality over 5 year period shows relatively stable water chemistry. - Abstract: Targeting shallow low-As aquifers based on sediment colour may be a viable solution for supplying As-safe drinking water to rural communities in some regions of Bangladesh and West Bengal in India. The sustainability of this solution with regard to the long-term risk of As-safe oxidized aquifers becoming enriched with As needs to be assessed. This study focuses on the adsorption behaviour of shallow oxidized sediments from Matlab Region, Bangladesh, and their capacity to attenuate As if cross-contamination of the oxidized aquifers occurs. Water quality analyses of samples collected from 20 tube-wells in the region indicate that while there may be some seasonal variability, the groundwater chemistry in the reduced and oxidized aquifers was relatively stable from 2004 to 2009. Although sediment extractions indicate a relatively low amount of As in the oxidized sediments, below 2.5 mg kg -1 , batch isotherm experiments show that the sediments have a high capacity to adsorb As. Simulations using a surface complexation model that considers adsorption to amorphous Fe(III) oxide minerals only, under-predict the experimental isotherms. This suggests that a large proportion of the adsorption sites in the oxidized sediments may be associated with crystalline Fe(III) oxides, Mn(IV) and Al(III) oxides, and clay minerals. Replicate breakthrough column experiments conducted with lactose added to the influent solution demonstrate that the high adsorption capacity of the oxidized sediments may be reduced if water drawn down into the oxidized aquifers contains high levels of electron donors such as

  8. Groundwater arsenic removal by coagulation using ferric(III) sulfate and polyferric sulfate: A comparative and mechanistic study.

    Elevated arsenic (As) in groundwater poses a great threat to human health. Coagulation using mono- and poly-Fe salts is becoming one of the most cost-effective processes for groundwater As removal. However, a limitation comes from insufficient understanding of the As removal mechanism from groundwater matrices in the coagulation process, which is critical for groundwater treatment and residual solid disposal. Here, we overcame this hurdle by utilizing microscopic techniques to explore molecular As surface complexes on the freshly formed Fe flocs and compared ferric(III) sulfate (FS) and polyferric sulfate (PFS) performance, and finally provided a practical solution in As-geogenic areas. FS and PFS exhibited a similar As removal efficiency in coagulation and coagulation/filtration in a two-bucket system using 5mg/L Ca(ClO)2. By using the two-bucket system combining coagulation and sand filtration, 500 L of As-safe water (<10 μg/L) was achieved during five treatment cycles by washing the sand layer after each cycle. Fe k-edge X-ray absorption near-edge structure (XANES) and As k-edge extended X-ray absorption fine structure (EXAFS) analysis of the solid residue indicated that As formed a bidentate binuclear complex on ferrihydrite, with no observation of scorodite or poorly-crystalline ferric arsenate. Such a stable surface complex is beneficial for As immobilization in the solid residue, as confirmed by the achievement of much lower leachate As (0.9 μg/L-0.487 mg/L) than the US EPA regulatory limit (5 mg/L). Finally, PFS is superior to FS because of its lower dose, much lower solid residue, and lower cost for As-safe drinking water. Copyright © 2015. Published by Elsevier B.V.

    To reduce arsenic (As) exposure, we evaluated the effectiveness of training community members to perform water arsenic (WAs) testing and provide As education compared to sending representatives from outside communities to conduct these tasks. We conducted a cluster based randomized controlled trial of 20 villages in Singair, Bangladesh. Fifty eligible respondents were randomly selected in each village. In 10 villages, a community member provided As education and WAs testing. In a second set of 10 villages an outside representative performed these tasks. Overall, 53% of respondents using As contaminated wells, relative to the Bangladesh As standard of 50 μg/L, at baseline switched after receiving the intervention. Further, when there was less than 60% arsenic contaminated wells in a village, the classification used by the Bangladeshi and UNICEF, 74% of study households in the community tester villages, and 72% of households in the outside tester villages reported switching to an As safe drinking water source. Switching was more common in the outside-tester (63%) versus community-tester villages (44%). However, after adjusting for the availability of arsenic safe drinking water sources, well switching did not differ significantly by type of As tester (Odds ratio = 0.86[95% confidence interval 0.42-1.77). At follow-up, among those using As contaminated wells who switched to safe wells, average urinary As concentrations significantly decreased. The overall intervention was effective in reducing As exposure provided there were As-safe drinking water sources available. However, there was not a significant difference observed in the ability of the community and outside testers to encourage study households to use As-safe water sources. The findings of this study suggest that As education and WAs testing programs provided by As testers, irrespective of their residence, could be used as an effective, low cost approach to reduce As exposure in many As-affected areas of

    Senores académicos, señoras, señores:

    Nuevamente nos reunimos aquí, en este noble recinto de la Academia Colombiana de la Lengua, esta vez para conmemorar, en fecha y hora casi exactas, los cien años de la promulgación de la ley organica que tiene existencia legal a nuestra Academia. Y digo existencia legal, porque ella ya existía en el espiritu y en las realizaciones de ese puñado de medicos bogotanos de finales del siglo XIX que, encabezados y guiados por Manuel Plata Azuero, Leoncio Barreto, Nicolas Osorio y Abraham Aparicio, entre otros, se habían congregado 18 años atras para fundar la Sociedad de Medicina y Ciencias Naturales que ahora, por decisión soberana del Congreso de la Republica,se tornaba en Academia Nacional de Medicina, el 22 de Noviembre de 1890.

    Es una fecha memorable, que nos obliga a mirar retrospectiva y prospectivamente y a preguntarnos que somos y que representamos nosotros, académicos, en el contexto de un siglo de existencia. Porque no podemos contentamos solamente con vivir de las glorias del pasado y decir que nos adueñamos, apenas, de un legado que otras generaciones, quizas mas objetivas y mas ambiciosas, construyeron pedazo a pedazo para nosotros. No. Este es un momenta que nos impele a un examen de conciencia y, sobre todo, a reflexionar sobre el papel que nuestra clase médica directiva viene ejerciendo y tendra que ejercer, ineluctablemente, en los destinos de la salud de Colombia.

    ¿Por que razón? Porque vivimos espocialmente un momento de cambio. Cambio que seguramente experimentaron y sintieron tambien los fundadores de nuestra Academia cuando, en las postrimerías del siglo XIX, se dieron cuenta de que, mientras en el mundo operaba a toda marcha la revolución industrial y se vislumbraba en el horizonte la caída de los imperios y de las monarquias, la medicina comenzaba lentamente tambien a remover sus bases anatomo-clínica y fisio-patológica, que habían funcionado ya durante mas de un siglo, y a entrar de lleno en la era etiopatológica con el advenimiento de Pasteur, de Koch y de la microbiología.Y que al tiempo, gracias a los avances de la anestesia, la antisepsia

    Research highlights: {yields} Adsorption behaviour of shallow oxidized sediments from Matlab Region in SE Bangladesh is investigated. {yields} Oxidized sediments have a high capacity to adsorb arsenic. {yields} Adsorption capacity will be reduced by high concentration of reactive organic C. {yields} Monitoring of groundwater quality over 5 year period shows relatively stable water chemistry. - Abstract: Targeting shallow low-As aquifers based on sediment colour may be a viable solution for supplying As-safe drinking water to rural communities in some regions of Bangladesh and West Bengal in India. The sustainability of this solution with regard to the long-term risk of As-safe oxidized aquifers becoming enriched with As needs to be assessed. This study focuses on the adsorption behaviour of shallow oxidized sediments from Matlab Region, Bangladesh, and their capacity to attenuate As if cross-contamination of the oxidized aquifers occurs. Water quality analyses of samples collected from 20 tube-wells in the region indicate that while there may be some seasonal variability, the groundwater chemistry in the reduced and oxidized aquifers was relatively stable from 2004 to 2009. Although sediment extractions indicate a relatively low amount of As in the oxidized sediments, below 2.5 mg kg{sup -1}, batch isotherm experiments show that the sediments have a high capacity to adsorb As. Simulations using a surface complexation model that considers adsorption to amorphous Fe(III) oxide minerals only, under-predict the experimental isotherms. This suggests that a large proportion of the adsorption sites in the oxidized sediments may be associated with crystalline Fe(III) oxides, Mn(IV) and Al(III) oxides, and clay minerals. Replicate breakthrough column experiments conducted with lactose added to the influent solution demonstrate that the high adsorption capacity of the oxidized sediments may be reduced if water drawn down into the oxidized aquifers contains high levels of

    Full Text Available The wide spread occurrence of geogenic arsenic (As in Bangladesh groundwater drastically reduced the safe water access across the country. Since its discovery in 1993, different mitigation options tested at household and community scale have resulted in limited success. In an arsenic hotspot of southeastern Bangladesh, 841 arsenic removal filter (ARF, 190 surface water filter membrane, 23 pond sand filter (PSF, 147 rain water harvester (RWH and 59 As-safe tubewell were distributed among the severely exposed population by AsMat, a Sida supported project. After three-four years of providing these safe water options, this study was carried out during 2010-2011 for performance analysis of these options, in terms of technical viability and effectiveness and thus to evaluate the preference of different options to the end users. Household and community based surveys were done to make an assessment of the current water use pattern as impact of the distributed options, overall condition of the options provided and to identify the reasons why these options are in use and/or abandoned. In total, 284 households were surveyed and information was collected for 23 PSF, 147 RWH and 59 tubewells. None of the filters was found in use. Among other options distributed, 13% of PSF, 40% RWH and 93% of tubewell were found functioning. In all cases, tubewells were found As-safe. About 89% of households are currently using tubewell water which was 58% before. Filter was abandoned for high cost and complicated maintenance. The use of RWH and PSF was not found user friendly and ensuring year round water quality is a big challenge. Arsenic-safe tubewell was found as a widely accepted option mainly because of its easy operation and availability of water, good water quality and negligible maintenance. This study validated tubewell as the most feasible option and holds significance for planning water supply projects, improving mitigation policy as well as developing awareness

    Full Text Available Abstract Objective To reduce arsenic (As exposure, we evaluated the effectiveness of training community members to perform water arsenic (WAs testing and provide As education compared to sending representatives from outside communities to conduct these tasks. Methods We conducted a cluster based randomized controlled trial of 20 villages in Singair, Bangladesh. Fifty eligible respondents were randomly selected in each village. In 10 villages, a community member provided As education and WAs testing. In a second set of 10 villages an outside representative performed these tasks. Results Overall, 53% of respondents using As contaminated wells, relative to the Bangladesh As standard of 50 μg/L, at baseline switched after receiving the intervention. Further, when there was less than 60% arsenic contaminated wells in a village, the classification used by the Bangladeshi and UNICEF, 74% of study households in the community tester villages, and 72% of households in the outside tester villages reported switching to an As safe drinking water source . Switching was more common in the outside-tester (63% versus community-tester villages (44%. However, after adjusting for the availability of arsenic safe drinking water sources, well switching did not differ significantly by type of As tester (Odds ratio =0.86[95% confidence interval 0.42-1.77. At follow-up, among those using As contaminated wells who switched to safe wells, average urinary As concentrations significantly decreased. Conclusion The overall intervention was effective in reducing As exposure provided there were As-safe drinking water sources available. However, there was not a significant difference observed in the ability of the community and outside testers to encourage study households to use As-safe water sources. The findings of this study suggest that As education and WAs testing programs provided by As testers, irrespective of their residence, could be used as an effective, low cost

  19. Energizing porters by proton-motive force.

    1994-11-01

    It is generally accepted that the chemistry of water was the most crucial determinant in shaping life on earth. Among the more important chemical features of water is its dissociation into protons and hydroxyl ions. The presence of relatively high proton concentrations in the ambient solution resulted in the evolution of proton pumps during the dawn of life on earth. These proton pumps maintained neutral pH inside the cells and generated electrochemical gradients of protons (proton-motive force) across their membranes. The existence of proton-motive force enabled the evolution of porters driven by it that are most probably among the more primitive porters in the world. The directionality of the substrate transport by the porters could be to both sides of the membranes because they can serve as proton symporters or antiporters. One of the most important subjects of this meeting is the mechanism by which proton-motive and other ion-motive forces drive the transport processes through porters. Is there a common mechanism of action for all proton-driven porters? Is there some common partial reaction by which we can identify the way that porters are energized by proton-motive force? Is there a common coupling between proton movement and uptake or secretion of certain molecules? Even a partial answer to one of these questions would advance our knowledge... or confusion. As my mentor Efraim Racker used to say: 'If you are not totally confused you do not understand the issue'.

    Semantic memory deficits in schizophrenia (SZ) are profound, yet there is no research comparing implicit and explicit semantic processing in the same participant sample. In the current study, both implicit and explicit priming are investigated using direct (LION-TIGER) and indirect (LION-STRIPES; where tiger is not displayed) stimuli comparing SZ to healthy controls. Based on a substantive review (Rossell and Stefanovic, 2007) and meta-analysis (Pomarol-Clotet et al., 2008), it was predicted that SZ would be associated with increased indirect priming implicitly. Further, it was predicted that SZ would be associated with abnormal indirect priming explicitly, replicating earlier work (Assaf et al., 2006). No specific hypotheses were made for implicit direct priming due to the heterogeneity of the literature. It was hypothesised that explicit direct priming would be intact based on the structured nature of this task. The pattern of results suggests (1) intact reaction time (RT) and error performance implicitly in the face of abnormal direct priming and (2) impaired RT and error performance explicitly. This pattern confirms general findings regarding implicit/explicit memory impairments in SZ whilst highlighting the unique pattern of performance specific to semantic priming. Finally, priming performance is discussed in relation to thought disorder and length of illness. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Influence of calmodulin antagonists on mitochondrial membrane potential was investigated using­ a flow cytometry method, confocal microscopy and fluorescent potential-sensitive probes TMRM and MTG. Influence of different concentrations of calmodulin antagonists on mitochondrial membrane potential was studied using flow cytometry method and a fraction of myometrium mitochondria of unpregnant rats. It was shown that 1-10 µМ calmidazolium gradually reduced mitochondria membrane potential. At the same time 10-100 µМ trifluope­razine influenced as follows: 10 µМ – increased polarization, while 100 µМ – caused almost complete depolarization of mitochondrial membranes. In experiments which were conducted with the use of confocal microscopy method and myometrium cells it was shown, that MTG addition to the incubation medium­ led to the appearance of fluorescence signal in a green range. Addition of the second probe (ТМRM resulted in the appearance of fluorescent signal in a red range. Mitochondrial membrane depolarization by 1µМ СССР or 10 mМ NaN3 was accompanied by the decline of “red” fluo­rescence intensity, “green” fluorescence was kept. The 10-15 minute incubation of myometrium cells in the presen­ce 10 µМ calmidazolium or 100 µМ trifluoperazine was accompanied by almost complete decrease of the TMRM fluorescent signal. Thus, with the use of potential-sensitive fluorescent probes TMRM and MTG it was shown, that calmodulin antagonists modulate mitochondrial membrane potential of myometrium cells.

PUs are preventable in a majority of cases. The increase in PU occurrence, however, appears regardless of higher awareness in prevention and improvement through utilization of pressure relieving devices. Multiple changes in the elderly body systems occur over time including aging, multiple chronic conditions, and functional impairment, potentially culminating in the final pathways of geriatric syndrome, unless awareness to the development of PUs is reversible and prevented. The assumption is that the development of PUs is based on multifactorial causes (extrinsic and intrinsic factors; thus, the optimal management for elderly patients requires a comprehensive approach in all medical settings (community, hospital, and at the long term care [LTC] level. Comprehensiveness signifies looking beyond the wounds, assisting the patient through both local (wound and systemic (medical condition treatment, using a strategy of prevention and supporting quality of life. Within the multidisciplinary involvement team approach, each professional discipline contributes its own task in coordination with other disciplines to address PU prevention, assessment, and treatment. The entire medical staff and the multidisciplinary team work together and communicate frequently in order to prevent, halt at an early stage, and provide healing in a timely fashion. Limiting the formation of PUs is facilitated through early identification, treating contributing causes, eliminating all unnecessary medications, instituting supportive interventions which include the family.

    Mastitis is one of the most important diseases affecting dairy sheep. Antimicrobial drugs are often administered directly through teat to treat or prevent this disease, but data on drug distribution within glandular tissue are scarce and it cannot be estimated from concentrations in milk. Thus, the aim of this study was to investigate systemic and mammary gland distribution of enrofloxacin after intramammary administration. The drug was administered to 6 healthy lactating Assaf sheep with an injector containing an enrofloxacin preparation (1 g drug/5 g ointment). Blood samples were collected at 0, 30, 60, 90, 120, 150 and 180 min. Animals were then sedated and sacrificed, and glandular tissue samples were obtained from treated udders at 2, 4, 6 and 8 cm height. Enrofloxacin concentrations were measured in plasma and tissue samples by UV high-performed liquid chromatography. Mean enrofloxacin plasma concentrations were below 0.5 μg/mL. Mean tissue concentrations decreased in mammary gland with vertical distance from the teat, ranging from 356.6 μg/g at 2 cm to 95.60 μg/g at the base of the udder. Glandular tissue concentrations best fitted to a decreasing monoexponential model, and showed a good correlation with an ex vivo model previously developed. Enrofloxacin concentrations were effective in the entire glandular tissue against the main pathogens causing mastitis in sheep. These results suggest that this drug may be suitable to treat mastitis in sheep by intramammary administration.

    Horse riding and horse handling are dangerous. There is a lack of knowledge concerning the incidence of hospitalization due to horse-related injuries and types of injuries in Israel. During the last two decades we have observed an increasing incidence of hospitalizations due to horse-related injuries at our medical center as well as the frequent involvement of pediatric patients. To investigate these injuries with respect to type, incidence and modes of prevention. We conducted a retrospective study of medical records for all patients admitted to Assaf Harofeh Medical Center due to horse-related injury between January 1984 and December 2008. A telephone questionnaire was used to complete the data. Eighty-nine subjects (267 injuries) were included in the study. Most of them were not professional horse riders or horse handlers. Helmet use was reported in only 28% of the participants. The number of subjects with horse-related injuries and the percentage of pediatric involvement increased during the study period. Falling from a horse was the most frequent cause of injury (60.67%), followed by being kicked (13.4%). Head and extremities were the most affected areas. On admission, 33.7% had a potential severe injury score. Forty-two participants (47%) had underlying fractures, mostly in the upper extremities. In the pediatric population, 16.2% (vs. 0% adults) rode horses for therapeutic reasons. Seventeen subjects reported having long-term consequences. The findings are similar to those described in other parts of the world. Horseback riding-related injuries are increasing, which emphasizes the need for safety education programs in Israel.

    Large studies which developed decision rules for the use of Computed tomography (CT) in children with minor head trauma excluded children with late presentation (more than 24h). To assess the prevalence of significant traumatic brain injury (TBI) on CT in infants with head trauma presenting to the emergency department (ED) more than 24h from the injury. A retrospective chart review of infants less than 24 months old referred for head CT because of traumatic brain injury from January 2004 to December 2014 in Assaf-Harofeh medical center was conducted. We used the PECARN definitions of TBI on CT to define significant CT findings. 344 cases were analyzed, 68 with late presentation. There was no significant difference in the age between children with late and early presentation (mean 11.4 (SD 5.6) month vs 10. 5 (SD 7.0) month, P=0.27). There was no significant difference between the groups in the incidence of significant TBI (22% vs 19%, p=0.61). Any TBI on CT (e.g. fracture) was found in 43 (63%) patients with late presentation compared with 116 (42%) patients with early presentation (p=0.002, OR 2.37, 95% CI 1.37-4.1). A similar rate of CT-identified traumatic brain injury was detected in both groups.‏ There was no significant difference in the incidence of significant TBI on CT between the groups.‏ Young children presenting to the ED more than 24 hours after the injury may have abnormal findings on CT.

About 38, 61, and 42 % of tubewells in Faizabad, Gonda, and Basti districts, respectively, have As >10 µg/l (WHO guideline). Moreover, 15, 45, and 26 % of tubewells in Faizabad, Gonda, and Basti districts, respectively, have As above 50 µg/l. About 86, 69, and 35 % of tubewells in Faizabad, Gonda, and Basti districts, respectively, are from shallow depth (21-45 m), and it is worth noticing that 47 % As-contaminated (As >10 µg/l) tubewells in these three districts are located within the depth of 10-35 m in Holocene Newer Alluvium aquifers. The high content of As (7.11 mg/kg) is measured in suspended river sediments of the Ghaghara River. Most of the As-contaminated villages in the Ghaghara Basin are located close to abandoned or present meander channels and floodplains of the Ghaghara River. In contrast, tubewells in Faizabad, Ayodhya, and Nawabganj towns are As-safe because of their positions on the Pleistocene Older Alluvium upland surfaces. Quaternary geomorphology plays an important role in groundwater arsenic contamination in the Ghaghara Basin. The sources of groundwater arsenic are geogenic and perennial mountainous rivers in the Ghaghara Basin supplied high sediment loads. The arsenic in groundwater of Ghaghara Basin is getting released from associated sediments which were likely deposited from the Himalayas. The process of release of groundwater arsenic is reductive dissolution of iron hydroxides.

    Mutations provide the raw material of evolution, and thus our ability to study evolution depends fundamentally on having precise measurements of mutational rates and patterns. We generate a data set for this purpose using (1) de novo mutations from mutation accumulation experiments and (2) extremely rare polymorphisms from natural populations. The first, mutation accumulation (MA) lines are the product of maintaining flies in tiny populations for many generations, therefore rendering natural selection ineffective and allowing new mutations to accrue in the genome. The second, rare genetic variation from natural populations allows the study of mutation because extremely rare polymorphisms are relatively unaffected by the filter of natural selection. We use both methods in Drosophila melanogaster , first generating our own novel data set of sequenced MA lines and performing a meta-analysis of all published MA mutations (∼2000 events) and then identifying a high quality set of ∼70,000 extremely rare (≤0.1%) polymorphisms that are fully validated with resequencing. We use these data sets to precisely measure mutational rates and patterns. Highlights of our results include: a high rate of multinucleotide mutation events at both short (∼5 bp) and long (∼1 kb) genomic distances, showing that mutation drives GC content lower in already GC-poor regions, and using our precise context-dependent mutation rates to predict long-term evolutionary patterns at synonymous sites. We also show that de novo mutations from independent MA experiments display similar patterns of single nucleotide mutation and well match the patterns of mutation found in natural populations. © 2017 Assaf et al.; Published by Cold Spring Harbor Laboratory Press.

    In forty six wells >150 m deep, from across the arsenic-polluted area of south-central Bangladesh, groundwater composition remained unchanged between 1998 and 2011. No evidence of deteriorating water quality was found in terms of arsenic, iron, manganese, boron, barium or salinity over this period of 13 years. These deep tubewells have achieved operating lives of more than 20 years with minimal institutional support. These findings confirm that tubewells tapping the deep aquifers in the Bengal Basin provide a safe, popular, and economic, means of arsenic mitigation and are likely to do so for decades to come. Nevertheless, concerns remain about the sustainability of a resource that could serve as a source of As-safe water to mitigate As-pollution in shallower aquifers in an area where tens of millions of people are exposed to dangerous levels of arsenic in well water. The conjunction of the stable composition in deep groundwater and the severe adverse health effects of arsenic in shallow groundwater lead us to challenge the notion that strong sustainability principles should be applied to the management of deep aquifer abstraction in Bangladesh is, the notion that the deep groundwater resource should be preserved for future generations by protecting it from adverse impacts, probably of a minor nature, that could occur after a long time and might not happen at all. Instead, we advocate an ethical approach to development of the deep aquifer, based on adaptive abstraction management, which allows possibly unsustainable exploitation now in order to alleviate crippling disease and death from arsenic today while also benefiting future generations by improving the health, education and economy of living children.

    We investigated the extent and severity of groundwater arsenic (As) contamination in five blocks in Patna district, Bihar, India along with As in biological samples and its health effects such as dermatological, neurological and obstetric outcome in some villages. We collected 1365 hand tube-well water samples and analyzed for As by the flow injection hydride generation atomic absorption spectrometer (FI-HG-AAS). We found 61% and 44% of the tube-wells had As above 10 and 50 μg/l, respectively, with maximum concentration of 1466 μg/l. Our medical team examined 712 villagers and registered 69 (9.7%) with arsenical skin lesions. Arsenical skin lesions were also observed in 9 children of 312 screened. We analyzed 176 biological samples (hair, nail and urine). Out of these, 69 people had arsenical skin lesions and rest without skin lesions. We found 100% of the biological samples had As above the normal levels (concentrations of As in hair, nail and urine of unexposed individuals usually ranges from 20 to 200 μg/kg, 20-500 μg/kg and Arsenical neuropathy was observed in 40.5% of 37 arsenicosis patients with 73.3% prevalence for predominant sensory neuropathy and 26.7% for sensor-motor. Among patients, different clinical and electrophysiological neurological features and abnormal quantitative sensory perception thresholds were also noted. The study also found that As exposed women with severe skin lesions had adversely affected their pregnancies. People including children in the affected areas are in danger. To combat As situation in affected areas, villagers urgently need (a) provision of As-safe water for drinking and cooking, (b) awareness about the danger of As toxicity, and (c) nutritious food.

    Full Text Available The equivalency canard Efraim Zuroff's text, originally published in Haaretz magazine, is a review of Timothy Snyder's Bloodlands. Snyder distinguishes six main mass murders commited by Nazi Germany and Soviet Union during the period of the Third Reich's existence. In Zuroff's opinion there are some significant differences between these tragedies. Dubious comparisons proposed by Snyder made the Holocaust most affected. Describing the Shoah as one of the six equally horryfying mass murders, the author ignores its ideological roots. Roots that sentenced to death all Jews  - regardless of their political views, religious practicies or the level of identification with Jewish community. Moreover Snyder takes no notice of the georaphical scope of the Holocaust. He also does not notice the fact, that the Nazis effectively managed to make so many Europeans their accomplices, who actively supported the Shoah.   Fałszywy znak równości Tekst Efraima Zuroffa, który pierwotnie ukazał się w piśmie Haaretz, to recenzja książki Skrwawione ziemie Timothy Snydera. Snyder wyróżnia sześć głównych masowych mordów popełnionych przez Niemcy i Związek Radziecki w okresie, który odpowiada istnieniu Trzeciej Rzeszy. Istnieją jednak, zdaniem Zuroffa, znaczące różnice między tymi tragediami. Na wątpliwych porównaniach, które proponuje Snyder, najbardziej „ucierpiał” Holokaust. Opisując Shoah jako jeden z sześciu równie straszliwych, masowych mordów, autor pomija jego ideologiczne korzenie, które sprawiały, że na śmierć skazany był każdy bez wyjątku Żyd, niezależnie od jego poglądów politycznych, praktyk religijnych czy stopnia identyfikacji z żydowską wspólnotą. Ponadto Snyder ignoruje ogromny zasięg geograficzny Holokaustu. Nie zauważa także skuteczności, z jaką naziści potrafili uczynić swoimi wspólnikami tak wielu Europejczyków, którzy w konsekwencji aktywnie wspomagali Shoah.

    Quantity and quality distribution of surface water and groundwater are changing under the impacts of both climate variability and human activities. The main goal of this paper is to evaluate the abovementioned impacts on the water resources in the Saveh plain, central Iran. To achieve this aim, spatial and temporal changes of the surface and groundwater quality and quantity have been analyzed, using hydrometric and meteorological data. The nonparametric Mann-Kendall test was used to identify trends and change points in the annual rainfall and runoff for the period of 1946 to 2011. In order to analyze the impacts of the Saveh Dam on runoff, the dam operation year, 1994, was considered as a change point. Mann-Kendall test results show that rainfall time series was divided into two parts, namely, 1966-1989 and 1990-2007, and averages of annual rainfall in five stations increase from 10 to 21 %. Also, runoff time series was divided into two parts, namely, 1946-1995 and 1996-2007 and averages of annual runoff in four stations decrease from 8 to 83 %. Results show that rainfall changes in Shahabasi, Razin, Jalayer, Emamabad, and Ahmadabad stations increased from 9 to 33 % before and after 1994. Nevertheless, runoff decreased from 24 to 81 %. The results indicate that the greatest lack of runoff between stations is at Shahabasi station and one important reason for the severe lack is operation of the Saveh Dam in 1994. Highest groundwater level decline, about 168.67 cm, occurred in 1994 that is the operation year of the Saveh Dam. Trend analysis of surface water quality show that electrical conductivity increased 957.34 μmho/cm before and after 1994. Also, the Wilcox water quality classification method has been reduced from C3-S1 to C4-S2. Average groundwater electrical conductivity (EC) during 1999-2003 and 2004-2009 increased to 89.6 μmho/cm. Also, the groundwater quality indices for agricultural usages are classified in four classes including, C4-S2 16, C4-S1 46, C3-S

    Full Text Available The DHET Research Output Policy (2015 indicates that there has been a change in the government’s approach to research funding. Previously all research published in any accredited journal was rewarded equally. A decision has been taken, however, that a shift will be made towards rewarding better quality and higher impact peer-review research. Additional mechanisms such as biometric/bibliometric data, including citations, assessments by discipline-specific panels of experts and/or post-publication reviews may be used to determine the quality and impact of publications. The policy notes that the DHET may distinguish between "high" and "low" impact journals after proper consultation. This article highlights the need for consultation by the legal fraternity with the DHET about the implementation of these possible mechanisms in the light of the special considerations applicable to the evaluation of law journals: most journals publish mainly local legal content, there is a limited number of active legal academics, the nature of legal research is not empirical, and a premium is placed on the writing of books. The research evaluates the available data between 2009 and 2014 in an attempt to assess if it would be appropriate to introduce a legal journal ranking system in South Africa. The article discusses direct and indirect forms of quality evaluation to inform possible ranking systems. This includes the data from the ASSAf expert panel evaluation of law journals in 2014 and other bibliometric data based on whether the journal is featured in international accredited lists, the size of its print-run, author prominence, rejection-rate, usage studies, and evaluations based on citations. An additional ranking system is considered, based on the five best outputs submitted to the National Research Foundation by applicants applying for rating. The article concludes that a law journal ranking system would be inappropriate for South Africa. None of the systems

    Supplementation of ruminant diets with plant oils and marine lipids is an effective strategy for lowering saturated fatty acid (FA) content and increasing the concentration of cis-9,trans-11 conjugated linoleic acid and long-chain n-3 FA in ruminant milk. However, changes in populations of ruminal microorganisms associated with altered biohydrogenation of dietary unsaturated FA are not well characterized. Twenty-five lactating Assaf ewes were allocated at random to 1 of 5 treatments composed of dehydrated alfalfa hay and concentrates containing no additional lipid (control), or supplemented with 25 g of sunflower oil and 0 (SO), 8 (SOMA(1)), 16 (SOMA(2)), or 24 (SOMA(3)) g of marine algae/kg of diet dry matter. On d 28 on diet, samples of rumen fluid were collected for lipid analysis and microbial DNA extraction. Appearance and identification of biohydrogenation intermediates was determined based on complementary gas chromatography and Ag+-HPLC analysis of FA methyl esters. Total bacteria and the Butyrivibrio group were studied in microbial DNA by terminal RFLP analysis, and real-time PCR was used to quantify the known Butyrivibrio bacteria that produce trans-11 18:1 or 18:0. Dietary supplements of sunflower oil alone or in combination with marine algae altered the FA profile of rumen fluid, which was associated with changes in populations of specific bacteria. Inclusion of marine algae in diets containing sunflower oil resulted in the accumulation of trans 18:1 and 10-O-18:0 and a marked decrease in 18:0 concentrations in rumen fluid. At the highest levels of supplementation (SOMA(2) and SOMA(3)), marine algae also promoted a shift in ruminal biohydrogenation pathways toward the formation of trans-10 18:1 at the expense of trans-11 18:1. Changes in the concentration of biohydrogenation intermediates were not accompanied by significant variations in the abundance of known cultivated ruminal bacteria capable of hydrogenating unsaturated FA.

A critical analysis of the Lebanese food industry in its main sectors, namely milk and its derivatives, red meat and white meat, was made from facility inspections, investigations and management manufacturing procedures and/or processing, as well as microbiological and chemical analysis of different samples. It showed the inadequacy or the failure of the measures adopted, either at the organoleptic quality of food produced or the safety of consumer foods. Hence the need for the establishment of a new management system, supported by appropriate governance and meet international requirements, resulting in an ongoing, controlled and acceptable risk, and the restoration and strengthening of trust in the Lebanese health system. However, health problems often exceeding their initial importance and direct effect of triggering factor - minimal disruption transforming rapidly into a major crisis - any food system finds himself constantly undermined with permanent instability. This instability is characteristic of complex phenomena, and therefore, it returns us to the theory that the system is considered as a network of interdependent actors working to the satisfaction of the consumer in a given geographical area. Such a system must necessarily be global; it must incorporate all stakeholders in the food chain and be able to self-adjust to permanent and continuous way. From these considerations, we propose to the Lebanese authorities, in addition to the new food safety legislation food, adopted in January 2015, a specific model based on the principle of systemic triangulation (governance, risk analysis, regulatory and legislation and operating as a global system of governance and management of

Es con el espíritu ferviente y agradecido de sus hijos pródigos, entre los que nos contamos decenas de médicos colombianos, que venimos, al tiempo de recordar con el nombre de este edificio a quien fuera uno de sus máximos exponentes en la medicina interna, a recoger y exaltar la savia de la institución que un día ya lejano nos acogiera con mano generosa. Y para destacar la huella de numerosos médicos ilustres que han traspasado sus arcadas benévolas, preocupados no sólo por aprender sino por después dar de sí lo mejor a la juventudes que los sucedieron y los siguen continuando en la ciencia y en el espíritu.

    Porque eso ha sido el Instituto en sus 60 años de vida gloriosa: una institución educadora, investigativa y formadora por excelencia. Ello estaba en la mente de sus fundadores y de aquellos que precedieron por más de una década su fundación física, cuyos nombres registra con orgullo la historia médica de nuestra patria y que afortunadamente, con sus apellidos inscritos en los basamentos de estas construcciones, viejas y nuevas, se siguen proyectando por generaciones, inspirando lo que debe ser el amor y el civismo por la nación de nuestros sueños.

    Habría que forzar la imaginación para situarnos en el mundo médico de hace setenta años, donde el portento de la medicina erajustamente el

    operar sin ninguna descontinuación, entra en su segundo decenio en vía de mejoramiento ahora, euando con lleno completo de escritores y numeroso público, los doctores Efraim Otero-Ruiz, presidente de la Corporaeión; Roberto García Rojas, competente Gerente General de Salvat, y quien esto escribe, procedimos a abrir el X Concurso en que durante un año, a partir de la fecha, se esperan los trabajos.

    27 obras premiadas y publicadas, algunas con mayor número de ediciones, justifican que el generoso patrocinador García Rojas y su inmediato colaborador Germán Linares, anuncien que el próximo premio de fines de 1991 tiene aprobada la asignación de un millón y medio de pesos ($1.500.000 para el libro victorioso. El premio continúa en el proceso de reunión Salvat-Hachette de París, recientemente aprobada, en que entra en juego el gran prestigio de ambas editoriales.

    Nadie duda que para un médico colombiano más vale el honor que el efectivo, la verdad no es optación para atender la propuesta formulada por el doctor Godofredo Sampedro Acevedo, Gerente General de “La Colonense”, para que anunciemos que en adelante se comiencen a elaborar los trabajos que se quieran presentar al 11IPremio Nacional de Medicina del Seguro de Vida Kolnische Rück, con US$5.000 al ganador.

    Tanto la Academia corno la Sociedad Colombiana de Medicina del Seguro, tienen asientos en el Jurado Calificador.

    El Premio Manuel Forero, donado a principios de siglo por ese distinguido académico, espera candidatos.

    Quienes sean señalados por sus respectivas Facultades de Medicina como los mejores residentes en los dos últimos años, recibirán aquí, con una modesta pero significativa suma, un trofeo que embellece la carrera: Juan N. Corpas en Cirugía, Carlos Esguerra y Roberto Franco en Medicina, son los ilustres nombres de las tres adjudicaciones.

    En su oportunidad la Academia adjudicó el Premio Roche que esa fIrma donó con ($1.000.000.

    Una nueva sede adecuadamente dotada siempre estuvo en la mente de nuestros expresidentes Académicos César Augusto Pantoja, Hernando Groot, Pablo Gómez Martínez, Jorge Cavelier Gaviria y Efraim Otero-Ruiz, con quienes me tocó en suerte trabajar 12 años consecutivos, cerca de ellos a través de mi cargo de Coordinardor de la Comisión Permanente de Biblioteca y Publicaciones y de la Revista MEDICINA que se ha venido publicando sin interrupciones dentro de un compañerismo ejemplar; además de otras distinciones operativas que me inducen a expresar gratitud.

    Ahora, además, como Secretario de la Coporación por elección unánime de la Asamblea hace dos años, he sido testigo ático de una intensa, inteligente e inagotable actividad que nuestro Presidente Académico Juan Jacobo Muñoz Delgado quien siempre con el visto bueno de la Junta Directiva, mediante un acelerado ritmo de trabajo se impuso la tarea de convertir en realidad inmediata tan anhelada y necesaria idea.

    En efecto, la nueva sede fue inaugurada oficialmente el día 2 de septiembre de 1993.

    Este Editorial es la constancia escrita de tal febril actividad que para proporcionar evidencia a los lectores de “MEDICINA” resumo en breves incisos que muestran el tránsito a un estado con superávit de excepción para esta clase de instituciones:

    1. Terminación de la obra ya iniciada de la remodelación arquitectónica, tanto exterior de seguridad y aspecto como interior con suficientes y modernas instalaciones.

    2. Cerramiento total con altas y elegantes rejas metálicas y doble portería por la calle 69 y la carrera 7a.

    3. Aparcadero lujosamente adoquinado, amplio y seguro para 30 automóviles.

    4. Decoración interior estéticamente consultada, bien lograda en cortinas y clásicas lámparas de cristal obsequiadas por conocidos académicos. Un par de originales urnas precolombianas en el hall de entrada.

    5. Zona social doble, amplia

    después de que úno se ha desvelado 4 o 5 años para escribir y lograr que le publiquen un libro, se encuentra a los amigos en las calles o en las reuniones y de golpe le salen, peyorativamente, con esta frase : “- Ala, por ahí vi tu librito…Cuándo me lo mandas?”

    Por eso me he curado en salud con el “Envío”, que aparece en la 6a. página:

    Lector:

    Hay quienes raudos y afanosos un libro escriben, último o primero, y después nos lo envían generosos dedicado con rasgos elogiosos… y regresan al mes por su dinero.

    Esto, que entre poetas fue frecuente, hoy afecta a abogados y a galenos. Se argumenta que, al menos, los gastos de edición son muy copiosos y que el autor, privado de repente de unos cuantos pesitos onerosos y enfrentado del agio a los venenos, debe enmendar su gesto decadente reprimiendo sus gestos dadivosos.

    No para tí, lector: esto es regalo, dádiva, donación, traspaso o beca. Por eso, sin gastarte ni una mueca si te parece malo ya lo podrás tirar a la caneca! Sólo recuerda: escribo estas estanzas con el ánimo austero de compartir contigo mis andanzas y dedicarte algunas remembranzas con el saludo de Efraim Otero.

    Antes de seguir adelante quiero dar gracias anticipadas al amigo y brillante Académico Alberto Gómez por su comentario y agradecer sobre todo a los prologuistas- epiloguistas, Académicos Humberto Roselli y Guillermo Sánchez Medina, a la Academia, a todos los que en una u otra forma ayudaron a sacar este libro adelante, a Martha, a Susanita, a Mauricio Pérez y señora –que diseñaron la bella carátula- a mi hija Pilar, que dibujó las ilustraciones y a la Editorial Kimpres, por haber sacado en tiempo récord una bonita edición con sólo una errata, casi imperceptible en la página 72 y así evitar la crítica que lanzaba el inmortal Luis Donoso en una de sus “charlas” a los tipógrafos o “cajistas”, como se los denominaba en épocas pretéritas (pues

    Señor doctor Efraim Otero-Ruíz, presidente de la Academia Nacional de Medicina; señor doctor César Augusto Pantoja, Secretario Perpetuo de la misma; demás Miembros de la Junta Directiva; Señores Académicos; señor doctor Carlos Esguerra Samper y demás miembros de la familia Esguerra; Señoras y Señores:

    Me honra sobremanera que los descendientes del eminente médico y profesor eximio Carlos Esguerra Gaitán me hayan escogido para pronunciar estas palabras, con motivo de cumplirse los cincuenta años del fallecimiento de quien fuera mi inolvidable maestro en la Facultad de Medicina de la Universidad Nacional, donde seguí sus enseñanzas en el Curso de Patología Interna. Para mí son inolvidables su carácter bondadoso, su comprensión, su paciencia y la profundidad de sus conocimientos, cualidades personales no frecuentes, indispensables para ser médico en el amplio sentido del vocablo.

    Permítanme los señores académicos y demás asistentes que me detenga un tanto en la ascendencia de quien fuera miembro destacado de nuestra corporación. Dicha ascendencia, vasca como es sabido, viene, según anota Francisco de Abrisqueta en su excelente obra “Vascos en Colombia”, de los “Esguerra (Eskerra o Ezguerra (Ezkerra. 1. En Gipuzkoa y en el Valle de Ruesga (Cantabria, en 1730.2. Variante de Ezguerra. 3. Vecinos de Segura en 1374, de Zumarragaen 1383, de Legazpiaen 1407”.4.

    Luis López de Mesa señala que el primer Esguerra que llegó a la Nueva Granada fue el Alférez don Miguel Esguerra y Rosas, casado con doña Isabel Valero de Tapia. Anota que entre los descendientes de un siglo después figuran los esposos Esguerra Cuervo y don Sebastián Esguerra Galvez, médico él, quien se distinguió en la Guerra de la Independencia. El recuento termina con don Domingo Esguerra Ortiz, galeno así mismo, quien fuera el primero en discriminar, como pandemia definida

    took. "I fell in love with Physics," he said, "and it changed my life." Bahcall graduated from Berkeley in 1956 with a degree in Physics. He received a master's degree from the University of Chicago, followed by a 1961 PhD in Physics from Harvard University. After a Research Fellowship at Indiana University working with Emil Konopinski on nuclear weak interactions, Bahcall received an invitation in 1962 to the California Institute of Technology (Caltech) to work with William A. Fowler, a Nobel Prize winner and expert in the field. Bahcall was working with Willy Fowler and others at the time and place that "nuclear astrophysics" was invented. There he became engaged with neutrino work and to Neta Assaf (then completing her PhD at Caltech) — the two constant loves of his life. John met Neta on a trip to Israel in 1965. She was a young physics graduate student "with a beautiful smile that stole my heart," he said. He spoke no Hebrew and she little English. After a dozen rejections, he got a date with her. They fell in love immediately and their love and friendship lasted a lifetime. "Marrying Neta was the best thing that ever happened to me," John frequently said. Safi Bahcall, their older son, recollects: "The persistence and never giving up was the theme for my dad; solar neutrinos, the Hubble Space Telescope, and the quest for scientific excellence are just a few other examples." Bahcall's first paper from Caltech, a one-page letter to the editor of the Astrophysical Journal, dated 1 December 1962 and entitled "The Solar Neutrino Flux" (written with Fowler, Icko Iben, and Richard Sears), proposed an experiment that might "provide a valuable experimental limit on the effective temperature for neutrino generation in the Sun". That paper set the course for a lifetime of research. The writing of scientific papers was, however, only one of Bahcall's many contributions to world science. He was an educator who changed the nature of postdoctoral training, and a scientific
