    The literature regarding the type series of Scinax perpusillus (Lutz & Lutz, 1939) presents two distinct numbers for the holotype. In 1973, thirty-four years after the description, Bertha Lutz associated numbers to the type series. This numbering has been followed by subsequent reviewers of Scinax ever since, with exception of Peixoto (1987) who assigned another number to the holotype. Our reevaluation of the literature and examination of the type series allowed us to access that, in both cases, the numbers were incorrectly assigned to the specimens and determine the proper museum numbers for this series.

  2. Adolpho Lutz and the origins of medical entomology in Brazil.

    Adolpho Lutz (1855-1940) formed a bridge between the Bahian Tropicalist School and post-Mansonian medicine. Before taking over as head of the São Paulo Bacteriological Institute (1893), Lutz traveled through a variety of regions and delved into various disciplines. In the 1880s, he was already arguing that leprosy was transmitted by mosquitoes. Carbuncles, cholera, and typhoid fever were then the accepted models for investigating the etiology of infectious diseases. Following the discovery of how malaria was transmitted, attention turned to hematophagous diptera. Physicians, bacteriologists, zoologists, and veterinarians reshaped the network of actors involved in the 'hunt' for the agents and transmitters of diseases, as they began relying on analogies with malaria and yellow fever. Edwin Ray Lankester, director of the British Museum (Natural History), launched then a worldwide investigation into species that might be linked to human disease. The species described by Lutz and his proposed classification system were vital to Frederick Theobald's fundamental work in medical entomology, published in the early twentieth century. In 1908, Lutz brought with him to the Oswaldo Cruz Institute a remarkable quantity of research and experiments in all branches of the newly created "tropical medicine," devoted especially to entomology.

    Antecedentes y Objetivo: En México, el 64% de los pacientes hospitalizados sufren de desnutrición hospitalaria y hasta un 100% en adultos mayores, se han estudiado las causas, entre ellas se destacan: la sub-alimentación, el tiempo de hospitalización, el catabolismo presente en diversas patologías, falta de interés o tiempo del personal que labora en los hospitales entre otras. El objetivo del presente trabajo fue obtener la prevalencia de sub-alimentación en los pacientes hospitalizados con soporte enteral, en el Centro Médico “Lic. Adolfo López Mateos” (CMLALM) durante el periodo Agosto – Octubre 2014. Metodología: Se diseñó un estudio observacional, transversal, descriptivo; con una población de 52 pacientes con soporte enteral en el que se analizó la prevalencia de pacientes con sub-alimentación a partir de la ministración de la dieta enteral y la prescripción nutricional calórica establecida, durante el periodo de Agosto – Octubre 2014. Resultados: Se realizaron medidas de tendencia central para obtener el porcentaje de pacientes con sub-alimentación calórica. La prevalencia de pacientes con sub-alimentación fue del 71%, con mayor predominio el sexo masculino (70%) y en un rango de edad entre 51 años y 61 años (43%). El servicio médico de hospitalización donde se encontró la mayor prevalencia de pacientes con sub-alimentación fue medicina interna afectando a 14 pacientes (38%), seguido de neurocirugía con 7 pacientes (19%) y unidad de cuidados intensivos (UCI) con 7 pacientes (19%); siendo el turno nocturno donde se presentó en mayor predominio la sub-alimentación. Conclusiones: La sub-alimentación afectó a 37 pacientes con soporte enteral los cuales representan el 71% de la población estudiada, esta cifra coincide con otros estudios similares. La causa principal de la sub-alimentación fue el incumplimiento en la ministración de la dieta enteral.

  8. Are we ready for sexual reorientation therapy in the U.S. military? A response to David W. Lutz.

    PubMed

    Hierholzer, Robert

    2004-01-01

    In his paper "The Catholic Church, the American Military, and Homosexual Reorientation Therapy," David W. Lutz ultimately concludes that it is "appropriate, and highly ethical" for the American military to offer reorientation therapy to help homosexuals overcome "the vice of sodomy." The major thrust of his paper, however, is to call for abandonment of the "Don't Ask/Don't Tell" policy currently in place in the military. Lutz's paper covers much ground, and this review begins by examining whether such a wide view is necessary for the ultimate conclusions. It goes on to ask whether Lutz has omitted to mention important considerations bearing on this issue, and whether Lutz's call for the introduction of reorientation therapy is a serious call or a symbolic response to homosexual activities. Lutz fails to address essential issues such as the actual experiences of other nations having homosexuals in the military, and issues regarding what constitutes "reorientation therapy," the latter leading to questions about how such a therapy would actually be implemented.

    Parasite findings in sambaquis (shell mounds) are scarce. Although the 121 shell mound samples were previously analysed in our laboratory, we only recently obtained the first positive results. In the sambaqui of Guapi, Rio de Janeiro, Brazil, paleoparasitological analysis was performed on sediment samples collected from various archaeological layers, including the superficial layer as a control. Eggs of Acanthocephala, Ascaridoidea and Heterakoidea were found in the archaeological layers. We applied various techniques and concluded that Lutz's spontaneous sedimentation technique is effective for concentrating parasite eggs in sambaqui soil for microscopic analysis. PMID:23579793

    Scanning Electron Microscopy was used to describe the eggs of Georgecraigius fluviatilis (Lutz). Length is 722.8±39.6 µm and width is 177.1±9.8 µm. Diameter of the micropylar disk, surrounded by an irregular flattened collar, is 28 µm. The outer chorionic sculpture consists of cells of irregular shapes, containing tubercles with pitted surface. In the ventral region, tubercles of several diameters are irregularly distributed in chorionic cells, while in the dorsal region one larger tubercle is surrounded by several smaller ones. The eggs appear to lack structures for adhesion, certainly unnecessary due to the habit of laying eggs separately on water surfaces.

    Purpose: To optimize clinical efficiency and shorten patient wait time by minimizing the time and effort required to perform the Winston-Lutz test before stereotactic radiosurgery (SRS) through automation of the delivery, analysis, and documentation of results. Methods: The radiation fields of the Winston-Lutz (WL) test were created in a “machine-QA patient” saved in ARIA for use before SRS cases. Images of the BRW target ball placed at mechanical isocenter are captured with the portal imager for each of four, 2cm×2cm, MLC-shaped beams. When the WL plan is delivered and closed, this event is detected by in-house software called EventNet which automates subsequent processes with the aid of the ARIA web services. Images are automatically retrieved from the ARIA database and analyzed to determine the offset of the target ball from radiation isocenter. The results are posted to a website and a composite summary image of the results is pushed back into ImageBrowser for review and authenticated documentation. Results: The total time to perform the test was reduced from 20-25 minutes to less than 4 minutes. The results were found to be more accurate and consistent than the previous method which used radiochromic film. The images were also analyzed with DoseLab for comparison. The difference between the film and automated WL results in the X and Y direction and the radius were (−0.17 +/− 0.28) mm, (0.21 +/− 0.20) mm and (−0.14 +/− 0.27) mm, respectively. The difference between the DoseLab and automated WL results were (−0.05 +/− 0.06) mm, (−0.01 +/− 0.02) mm and (0.01 +/− 0.07) mm, respectively. Conclusions: This process reduced patient wait times by 15–20 minutes making the treatment machine available to treat another patient. Accuracy and consistency of results were improved over the previous method and were comparable to other commercial solutions. Access to the ARIA web services is made possible through an Eclipse co-development agreement

  12. SU-E-J-117: Verification Method for the Detection Accuracy of Automatic Winston Lutz Test

    Tang, A; Chan, K; Fee, F; Chau, R

    2014-06-01

    Purpose: Winston Lutz test (WLT) has been a standard QA procedure performed prior to SRS treatment, to verify the mechanical iso-center setup accuracy upon different Gantry/Couch movements. Several detection algorithms exist,for analyzing the ball-radiation field alignment automatically. However, the accuracy of these algorithms have not been fully addressed. Here, we reveal the possible errors arise from each step in WLT, and verify the software detection accuracy with the Rectilinear Phantom Pointer (RLPP), a tool commonly used for aligning treatment plan coordinate with mechanical iso-center. Methods: WLT was performed with the radio-opaque ball mounted on a MIS and irradiated onto EDR2 films. The films were scanned and processed with an in-house Matlab program for automatic iso-center detection. Tests were also performed to identify the errors arise from setup, film development and scanning process. The radioopaque ball was then mounted onto the RLPP, and offset laterally and longitudinally in 7 known positions ( 0, ±0.2, ±0.5, ±0.8 mm) manually for irradiations. The gantry and couch was set to zero degree for all irradiation. The same scanned images were processed repeatedly to check the repeatability of the software. Results: Miminal discrepancies (mean=0.05mm) were detected with 2 films overlapped and irradiated but developed separately. This reveals the error arise from film processor and scanner alone. Maximum setup errors were found to be around 0.2mm, by analyzing data collected from 10 irradiations over 2 months. For the known shift introduced using the RLPP, the results agree with the manual offset, and fit linearly (R{sup 2}>0.99) when plotted relative to the first ball with zero shift. Conclusion: We systematically reveal the possible errors arise from each step in WLT, and introduce a simple method to verify the detection accuracy of our in-house software using a clinically available tool.

  13. On the selection of gantry and collimator angles for isocenter localization using Winston-Lutz tests.

    In Winston-Lutz (WL) tests, the isocenter of a linear accelerator (linac) is determined as the intersection of radiation central axes (CAX) from multiple gantry, collimator, and couch angles. It is well known that the CAX can wobble due to mechanical imperfections of the linac. Previous studies suggested that the wobble varies with gantry and collimator angles. Therefore, the isocenter determined in the WL tests has a profound dependence on the gantry and collimator angles at which CAX are sampled. In this study, we evaluated the systematic and random errors in the iso-centers determined with different CAX sampling schemes. Digital WL tests were performed on six linacs. For each WL test, 63 CAX were sampled at nine gantry angles and seven collimator angles. Subsets of these data were used to simulate the effects of various CAX sampling schemes. An isocenter was calculated from each subset of CAX and compared against the reference isocenter, which was calculated from 48 opposing CAX. The differences between the calculated isocenters and the reference isocenters ranged from 0 to 0.8 mm. The differences diminished to less than 0.2 mm when 24 or more CAX were sampled. Isocenters determined with collimator 0° were vertically lower than those determined with collimator 90° and 270°. Isocenter localization errors in the longitudinal direction (along the axis of gantry rotation) showed a strong dependence on the collimator angle selected. The errors in all directions were significantly reduced when opposing collimator angles and opposing gantry angles were employed. The isocenter localization errors were less than 0.2 mm with the common CAX sampling scheme, which used four cardinal gantry angles and two opposing collimator angles. Reproducibility stud-ies on one linac showed that the mean and maximum variations of CAX during the WL tests were 0.053 mm and 0.30 mm, respectively. The maximal variation in the resulting isocenters was 0.068 mm if 48 CAX were used, or 0

    We develop an exact and flexible mathematical model for Lutz and Bujard's controllable promoters. It can be used as a building block for modeling genetic systems based on them. Special attention is paid to deduce all the model parameters from reported (in vitro) experimental data. We validate our model by comparing the regulatory ranges measured in vivo by Lutz and Bujard against the ranges predicted by the model, and which are calculated as the reporter activity obtained under inducing conditions divided by the activity measured under maximal repression. In particular, we verify Bond et al. assertion that the cooperativity between two lac operators can be assumed to be negligible when their central base pairs are separated by 22 or 32 bp [Gene repression by minimal lac loops in vivo, Nucleic Acids Res, 38 (2010) 8072-8082]. Moreover, we also find that the probability that two repressors LacI bind to these operators at the same time can be assumed to be negligible as well. We finally use the model for the promoter P(LlacO-1) to analyze a synthetic genetic oscillator recently build by Stricker et al. [A fast, robust and tunable synthetic gene oscillator, Nature, 456 (2008) 516-519].

    Stereotactic radiosurgery requires sub-millimetre accuracy in patient positioning and target localization. Therefore, verification of the linear accelerator (linac) isocentre and the laser alignment to the isocentre is performed in some clinics prior to the treatment using the Winston-Lutz (W-L) test with films and more recently with images obtained using the electronic portal imaging devices (EPID). The W-L test is performed by acquiring EPID images of a radio-opaque ball of 6 mm diameter (the W-L phantom) placed at the isocentre of the linac at various gantry and table angles, with a predefined small square or circular radiation beam. In this study, the W-L test was performed on two linacs having EPIDs of different size and resolution, viz, a TrueBeam™ linac with aS1000 EPID of size 40 × 30 cm(2) with 1024 × 768 pixel resolution and an EDGE™ linac having an EPID of size 43 × 43 cm(2) with pixel resolution of 1280 × 1280. In order to determine the displacement of the radio-opaque ball centre from the radiation beam centre of the W-L test, an in-house MATLAB™ image processing code was developed using morphological operations. The displacement in radiation beam centre at each gantry and couch position was obtained by determining the distance between the radiation field centre and the radio-opaque ball centre for every image. Since the MATLAB code was based on image processing that was dependent on the image contrast and resolution, the W-L test was also compared for images obtained with different beam energies. The W-L tests were performed for 6 and 8 MV beams on the TrueBeam™ linac and for 2.5 and 6 MV beams on the EDGE™ linac with a higher resolution EPID. It was observed that the images obtained with the EPID of higher resolution resulted in same accuracy in the determination of the displacement between the centres of the radio-opaque ball and the radiation beam, and significant difference was not observed with images acquired with

    In Spain, there is an Instituto de Astrofísica de Canarias in Tenerife, an Instituto de Astrofísica de Andalucía in Granada and an Institut d'Estudis Espacials de Catalunya in Barcelona. However, there is not an Instituto de Astrofísica de Madrid (IAM). Actually, Madrilenian astronomers are spread over a number of institutions of quite different origin, size and funding source. The IAM, if it existed, would be a catalyzer of ideas and collaborations, an international meeting point, an engine for high-technology industry in the region, and an excellence centre. Furthermore, the IAM would maximise the efficiency in the use of resources, offer a place for finding synergies between research groups and, especially, have a critical mass for embarking in very large projects in the ground and space. I will expose how, in a smooth and democratic way, an IAM might be built step by step. The process may take decades and, thus, young Madrilenian astronomers shall play a rôle on it.

    Abstract The male of Tityus kuryi Lourenço, 1997 is described for the first time. Despite being very similar to the female, the male presents more robust metasomal segments. Additionally, the distribution of the sexual populations of another two species of the T. stigmurus complex is reported herein: T. serrulatus Lutz & Mello, 1922 and T. stigmurus (Thorell, 1877). Males of T. serrulatus were, until now, restricted to the Minas Gerais State (Southwestern region of Brazil), and with new records reported here, its known distribution now encompasses the Northeastern region of Brazil. Males of T. stigmurus were previously recorded only for two municipalities in the State of Bahia, and here we present eight new records for Bahia State and one for Pernambuco State. We present a key to related species of the T. stigmurus complex based on morphology and coloration pattern. PMID:25152686

    The purpose of these lines is to remember and refer some of the historical landmarks in the evolution of the medical services of the Instituto Mexicano del Seguro Social (IMSS, according to its initials in Spanish) since it was founded, in 1943. We also want to bring to the reader's attention that the dimensions and impacts on health that IMSS has achieved, throughout its history, have strengthened the citizenship, as well as social sustainability. Also, those impacts have determined the creation and the reinforcement of human capital in México. Throughout this concise balance, all the controversy surrounding the foundation of the Institute is being recalled (the protest in the Mexico City Zócalo, or the attack to an hospital in San Ángel -a neighborhood located in the Southwest of Mexico City-), as well as the way the IMSS incorporated several words into the vocabulary of Mexicans. We also remember the previous antecedent of the Revista Médica del Instituto Mexicano del Seguro Social, as well as the Revista de Enfermería, and the emblematic Archives of Medical Research. The IMSS has 70 years of achievements, seven decades covered.

    Considering the limited opportunities and resources for creative education, artists David Bade and Tirzo Martha, along with art historian Nancy Hoffmann, developed a dynamic platform to support creative young talent on the Dutch Caribbean island of Curaçao. The aim of Instituto Buena Bista (IBB), founded in 2006, is to strengthen the arena of culture and the visual arts by offering young Curaçaoans a basic but thorough course in art education that is meant to function as a springboard to more advanced art schools. With only two years of operation, the IBB is already seeing how some of its students go to art academies abroad and participate in art contests in the Netherlands. An exploration of how the IBB is filling up a cultural void by proposing an alternative to local youth education that allows them to develop a buena bista-a new and different view of their island, their futures, and themselves.

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

    The journals of medicine arose as a communication tool more than 200 years ago. At the beginning, their nature was local; later, their aim was to spread medical information along the nation; and, finally, they sought to reach the world distribution. The Revista Médica del Instituto Mexicano del Seguro Social was published for the first time 52 years ago, and it has walked its way from local to international distribution. This journal has 23 000 subscribers, it is included in Medline and it reached a 0.112 SCImago Journal Rank in 2012. Its website receives around 200 000 visits monthly and 45 % are foreign visits. In the future, the peer review system is going to be strengthened, and the journal is going to offer audio, video, and applications to reinforce interactive participation between authors, readers in order to reach modernity and draw young new attention.

    Diabetes is major contributor to the mortality in the Mexican population and particularly in the population insured by social security institutions like The Instituto Mexicano del Seguro Social (IMSS). Mortality rates have duplicated from 1990 to 2005 period and in some regions the increment has been even higher and faster. Men not insured by IMSS present the lowest mortality rates. Mortality by chronic diseases is no longer a problem of affluent regions since Chiapas, Oaxaca and Guerrero, the poorest states in the country, have higher rates of increment than the northern and more developed regions. The different interventions employed by the health institutions should impact mortality rates in both the magnitude and velocity of increment especially in those regions where growth of mortality have been higher.

    Mortality is an indicator that allow us to evaluate HIV infection control programs. From the middle of the last decade, mortality presents a tendency to decrease in the population covered by the Instituto Mexicano del Seguro Social). In relation to gender and age group the most affected are men between 25 to 44 years of age with mortality rates ranging from 30 to 12 by 100,000 men (1995 to 2009 respectively). In 2009, at least half of the Delegaciones (administrative units by State) present larger mortality rates than the institutional average, particularly Campeche with 14.9 by 100,000 men. It is clear that introduction of control measures against the disease from infected people represents a modification in the course of the illness in the population covered by IMSS.

    The Real Instituto y Observatorio de la Armada (ROA) meridian circle was moved to the Estación de Altura Carlos Ulrrico Cesco in the República Argentina in 1996. Until November 1999 the observations were carried out with a moving slit micrometer. In spring 2001 the result of these observations has been published, forming the first Hispano-Argentinian Meridian Catalogue (HAMC). In December 1999 was installed a SpectraSource CCD camera of 1552×1024 pixels of 9 μ. The CCD camera observes in drift scan mode. A survey of the southern hemisphere is being observed from +3° to -60° of declination. In this contribution is presented a description of the telescope and the automatic control system, the results of observations carried out with the slit micrometer, and the observational and preliminary reduction techniques with the CCD camera, the present state of the southern hemisphere survey and the future possibilities.

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

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

    At the Instituto Materno Infantil (IMI) in Bogotá (Colombia), 5,686 births (5,597 live births and 89 stillbirths) were analyzed during two periods: from October, 1997, to April, 1998, and from July to November, 2000 (12 months). Congenital anomalies were detected in 4.4% of live newborn babies and in 7.8% of stillbirths. Major anomalies corresponded to 69% and mild anomalies to 31% (3% and 1.4% of all live births, respectively). The newborn babies with major anomalies, in comparison to the normal controls, had higher mortality at hospital discharge (p = 0.0001), lower average birth weight (p = 0.003), and family history of congenital anomalies (p = 0.0001). The only significant association for mild anomalies was with family history of congenital anomalies (p = 0.0001). The frequency of congenital anomalies was similar to that in other studies, although certain kinds of anomalies showed noticeable frequency differences. This may be a consequence of differences in record keeping or in detection methods.

    The Instituto Mexicano del Seguro Social--always sensitive to the needs of health of the beneficiary population and to the demographic and epidemiological changes of the society--has developed and implemented DiabetlMSS, a program of attention to the diabetic patient. DiabetlMSS organizes care processes based on the needs and values of the patients, through simultaneous activities of individual consultation and group meetings granted by the multidisciplinary health team. These actions and activities are focused to affect patients' lifestyles positively. Through a plan of nutrition, physical activity, self-care and monitoring, this program increases the interaction between patients, by having an exchange of successful experiences about diabetes control. DiabetlMSS was created with the purpose that the patients achieve the metabolic control and identify complications early on, with the perspective of timely intervention that is reflected in the decrease of the catastrophic effects that causes the disease, both for patient's life expectancy and the quality of care provided by the Institute.

    Electroconvulsive therapy (ECT) is a useful option for the treatment of certain psychiatric illnesses. Its efficacy and few side effects make it an important therapeutic alternative in the management of the patient with major depression. This study describes the clinical experience with ECT at the Instituto Mexicano de Psiquiatría. We retrospectively evaluated the clinical records of patients treated with ECT during the period of April 1990 to June 1994. A total of 55 patients were included in the analysis, the mean age was 42.4 +/- 17.2 years old. Diagnostic categories treated were major depression (43.6%), non-affective psychotic disorders (30.9%), mania (12.7%) and other diagnoses (12.7%). A positive response to ECT was found in 74.5% of patients. Subjects with major depression and mania responded significantly better than the rest of the patients (p < 0.01). Psychotic depression was not a predictor of better response. Only 18.1% of subjects had minor complications, all transitory. ECT is a highly effective therapeutic option in the treatment of psychiatric illness, especially in major depression and mania. The use of ECT in a tertiary psychiatric unit in Mexico reflects similar results as described in the international literature.

    The aim of this study was to evaluate the epidemiological, clinical and laboratorial profile of patients with Baggio-Yoshinari Syndrome (BYS), who underwent internment at the Instituto de Infectologia Emilio Ribas in São Paulo, Brazil, during the period from July 1990 to July 2006. BYS is a new Brazilian tick-borne disease caused by Borrelia burgdorferi sensu lato microorganisms that resembles features of Lyme disease (LD), except for its epidemiological, clinical and laboratorial particularities. From 60 patients' records with positive serology to B. burgdorferi done by ELISA and Western-blotting methods, 19 cases were diagnosed as having BYS, according to criteria adopted at LIM-17 HCFMUSP, the Brazilian Reference Laboratory for the research of BYS. The other 41 remaining patients displayed miscellaneous infections or auto-immune processes. The beginning of symptoms in BYS group varied from one day to six years, from the onset of the disease. Four of 19 patients were included in acute disease stage, and 15 in latent. General unspecific symptoms were identified in almost all cases, with high frequencies of fever (78.9%) and lymphadenomegaly (36.8%). Six patients had skin lesions (31.5%); six arthralgia or arthritis (31.5%) and eight neurological symptoms (42%). Interestingly, two patients showed antibodies directed to B. burgdorferi exclusively in cerebrospinal fluid. Since BYS is a new emergent Brazilian zoonosis and its diagnosis is sometimes complex, all the new knowledge about BYS must be scattered to Brazilian Medical specialists, aiming to teach them how to diagnose this amazing tick-borne disease and to avoid its progression to chronic irreversible sequels.

    Tuberculosis (TB) is an infectious disease of global distribution, constituting a serious public health problem in Brazil. São Paulo State, located in the south-east of Brazil, notified 16,580 new TB cases in 2013. The Instituto Adolfo Lutz is a public health reference laboratory for TB diagnosis for all the State. Considering that rapid and accurate diagnosis is essential for TB control, the aim of this study was to evaluate the use of an in-house real-time (RT)-PCR assay targeting the mpt64 gene in the routine diagnosis of TB, and to compare this technique with smear microscopy and culture. From August 2012 to October 2013, 715 sputum samples from 657 patients were included in the study. Smear microscopy, culture, phenotypic and PRA-hsp65 identification of mycobacteria, and mpt64 RT-PCR were performed. With respect to confirmed TB cases (n = 62/657; 9.4%), smear microscopy had a sensitivity of 82.3%. Culture and RT-PCR showed the same sensitivity, i.e. 90.3%. Specificity was 99.7, 99.4 and 98.6% for smear microscopy, culture and RT-PCR, respectively. mpt64 RT-PCR showed high sensitivity and specificity for the detection of Mycobacterium tuberculosis complex in sputum samples. This technique can be deployed in laboratories that do not have a rapid test for TB available, enabling the performance of TB diagnosis in up to 5 h.

    In May 2007, the Instituto Carso de la Salud—now Instituto Carlos Slim de la Salud (ICSS)—was endowed with US$500 million to focus on priority health issues in Latin America, notably issues of ‘globalisation and non-communicable diseases’. ICSS was soon criticised, however, on the grounds that its funding was derived from tobacco industry profits and that its founder Carlos Slim Hélu remained an active industry principal. Collaboration with ICSS was said to run counter to the WHO Framework Convention on Tobacco Control. The Institute's then Executive President Julio Frenk disputed these charges. This research employs an archive of tobacco industry documents triangulated with materials from commercial, media, regulatory and NGO sources to examine the financial relations between Slim and the tobacco industry. The paper analyses Slim's continuing service to the industry and role in ICSS. It demonstrates a prima facie conflict of interest between ICSS's health mission and its founder's involvement in cigarette manufacturing and marketing, reflected on ICSS's website as a resounding silence on issues of tobacco and health. It is concluded that the reliance of international health agencies upon the commercial sector requires more robust institutional policies to effectively regulate conflicts of interest. PMID:21088061

    A detailed retrospective analysis of 260 patients with T 1 NO MO vocal cord carcinoma treated at "Instituto de Oncologia y Radioterapia de Mar del Plata" from 1967 to 1985 was performed. The majority of the patients were in the age range of 50 to 79 years, and 79% were males. The overall observed three year tumor free survival was 85.3%. When survival rate was adjusted for intercurrent disease and second primary tumor death, the 3 year tumor free survival was 92%. Sixty two percent of the patients (17/27) undergoing surgical salvage for recurrence, were controlled. Second primary tumors were seen in 18 patients (6.9%). It is emphasized the importance of close follow up to diagnose as early as possible both the vocal cord recurrence and the second primary tumors.

Dosemeters were placed during a five month period in the nuclear medicine rooms (containing gamma-cameras), injection corridor, patient waiting areas, PET/CT study room, hot lab, waste storage room and corridors next to the hospitalization rooms for patients treated with 131I and 137Cs. High dose values were found at the waste storage room, outside corridor of 137Cs brachytherapy patients and PET/CT area. Ambient dose equivalent rate obtained for the 137Cs brachytherapy corridor is equal to (18.51±0.02)×10-3 mSv/h. Sites with minimum doses are the gamma camera rooms, having ambient dose equivalent rates equal to (0.05±0.03)×10-3 mSv/h. Recommendations have been given to the Department authorities so that further actions are taken to reduce doses at high dose sites in order to comply with the ALARA principle (as low as reasonably achievable).

    Ninety-nine children admitted to the Instituto Materno Infantil de Pernambuco with severe malnutrition from May 1999 to May 2000 were investigated in a cross-sectional study focusing on key epidemiological and clinical variables. The majority of the children (88.9%) were less than 6 months of age, 42.4% had a history of low birth weight, and 36.4% were premature. Some 19.2% had never been breastfed, and 49.5% had been breastfed for less than 2 months. Some 15.2% of the mothers were illiterate. Most of the families (86.1%) had incomes less than twice the minimum wage (approximately US$150/month), and 51.5% had migrated from rural areas. Only 26.3% of the homes had running water, and 40.4% lacked sewage disposal facilities. Diarrhea was the reason for hospital admission in 55.6% of the cases. Hospital mortality was 34.3% in this group.

    The most critical phase of exposure to schistosomal infection is the infancy, because of the more frequent contact with contaminated water and the immaturity of the immune system. One of the most severe presentations of this parasitosis is the involvement of the spinal cord, which prognosis is largely dependent on early diagnosis and treatment. Reports on this clinical form of schistosomiasis in children are rare in the literature. We present here the clinical-epidemiological profile of schistosomal myeloradiculopathy (SMR) from ten children who were admitted at the Instituto Materno-Infantil de Pernambuco over a five-year period. They were evaluated according to an investigation protocol. Most of these patients presented an acute neurological picture which included as the main clinical manifestations: sphincteral disorders, low back and lower limbs pain, paresthesia, lower limbs muscle weakness and absence of deep tendon reflex, and impairment of the gait. The diagnosis was presumptive in the majority of the cases. This study emphasizes the importance of considering the diagnosis of SMR in pediatric patients coming from endemic areas who present a low cord syndrome, in order to start the appropriate therapy and avoid future complications.

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

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

    This article follows the career of the Brazilian physician Henrique da Rocha Lima, one of the first to join the group of young researchers working at the Instituto Soroterápico de Manguinhos (Instituto Oswaldo Cruz). It describes his first voyage to Germany where he specialized in microbiology and pathological anatomy, training that shaped his subsequent professional identity. The tensions and dilemmas experienced by Rocha Lima provide an insight into what it meant to dedicate oneself to a scientific career in Brazil at the start of the twentieth century. They also reveal the importance of the relations with the German-speaking world for the experimental medicine that became established under the leadership of Oswaldo Cruz.

    1985 was a year of inauguration for the Instituto de Astrofísica de Canarias (IAC). In that year its two observatories, the Observatorio del Roque de los Muchachos, on the island of La Palma, (where its 10.4m optical-NIR telescope vies with the world´s major instruments), and the Observatorio del Teide, on the island of Tenerife, as well as its headquarters in La Laguna, Tenerife, were all inaugurated. This young institution has rapidly become the leading research centre for astronomy in Spain and achieved research standards at a European and world level. The 30th anniversary celebrations this year give an opportunity to maximize its already very active outreach programmes. In February two shows, featuring IAC researchers, and with astronomical themes, were shown in the main theatre of the city of La Laguna, and during the year further entertainment, collaborating with Canarian musicians and artists, is planned. Two exhibitions have been designed combining the anniversary with celebrations of the International Year of Light: “Listen to the Universe”, in Tenerife, and “Thirty Journeys around the Sun”, in La Palma, which will be open to the public for most of the year. A new outreach magazine “Parallaxes” will be launched by the IAC, in both paper and digital editions, and will complement the current blog, and news websites of the institute, as well as its communications on Facebook and Twitter. Among the activities being organized in Tenerife will be the formal naming of traffic circles with names of the telescopes at the Observatories. In conjunction with the municipal wine cellars of the local city of Tegueste a new Canarian wine produced by innovative methods and with an astronomical motif on its label, is to be launched during the year. All of these activities are in addition to the somewhat more routine productions of videos on the research lines of the IAC, including exoplanets, solar stellar, and interstellar physics, galaxies, and cosmology.

    The superficial mycoses are very common infectious diseases and therefore are a frequent reason for medical consultation. The aim of this study was to determine the diagnostic frequency of superficial mycoses in the Mycology Department of the Instituto Nacional de Higiene "Rafael Rangel" during 14 years (2001-2014). A retrospective cross-sectional study was performed to review the mycological records of patients with presumptive diagnosis of superficial mycosis. Nails, hairs and epidermal scales were the processed samples. The identification of fungi was performed by macro and microscopic observation of colonies and biochemical and physiological tests, as required of the isolated agent. For the investigation of Malassezia spp. only direct examination was performed. Of the 3 228 samples processed, 1 098 (34%) were positive and their distribution according to the etiological agent was: dermatophytes 79.5%; 10.9% yeasts; non-dermatophytes fungi 5.1% and 4.5% Malassezia spp. The most frequently isolated dermatophyte was Trichophyton rubrum Complex (70.1%), followed by T mentagrophytes complex (15.1%), Microsporum canis (9.4%) and Epidermophyton floccosum (4%). The most frequent ringworms Were: Tinea unguium (66.8%), followed by Tineapedis (16.4%) and Tinea capitis (8.1%). Candida parapsilosis complex (37.5%) was the most frequently isolated yeast and Fusarium spp. (53.6%) was the most isolated among non-dermatophyte fungi, followed by Aspergillus spp. (19.6%) and Acremonium spp. (10.7%). The identification of the etiological agent is essential to guide appropriate treatment. This study constitutes an important contribution to the knowledge of the epidemiology of superficial mycoses in our country. PMID:27382801

    Coccidioidomycosis is an emerging fungal disease in Brazil; adequate maintenance and authentication of Coccidioides isolates are essential for research into genetic diversity of the environmental organisms, as well as for understanding the human disease. Seventeen Coccidioides isolates maintained under mineral oil since 1975 in the Instituto de Medicina Tropical de São Paulo (IMTSP) culture collection, Brazil, were evaluated with respect to their viability, morphological characteristics and genetic features in order to authenticate these fungal cultures. Only five isolates were viable after almost 30 years, showing typical morphological characteristics, and sequencing analysis using Coi-F and Coi-R primers revealed 99% identity with Coccidioides genera. These five isolates were then preserved in liquid nitrogen and sterile water, and remained viable after two years of storage under these conditions, maintaining the same features.

    Research is a main element for human and social development. Under this point of view, it involves particular challenges and opportunities for the so-called "developing countries". An approach for those challenges and opportunities comes from the analysis of two interrelated activities; the training of new researchers and the research development with institutions or researchers which are external to the institution ("collaborative research"). Both activities are essential for the consolidation, widening and updating of the institutional capabilities for scientific production. We present here the experiences of the Instituto de Medicina Tropical "Alexander von Humboldt" of the Universidad Peruana Cayetano Heredia, in relation to the training of new researchers, we discuss the four elements we consider key for this process; the promotion of stimulating environments for research, the proactive identification of fellows, the complementary advice and networks consolidation; and we analyze three successful models of international collaboration for the training of new researchers under different institutional approaches.

    Abstract The bird collection of the Instituto de Investigação Cientítica Tropical (Lisbon, Portugal) holds 5598 preserved specimens (skins), mainly from Angola, Mozambique, Guinea-Bissau, São Tomé and Principe, and Cape Verde. The subset collection from Angola includes 1560 specimens, which were taxonomically revised and georeferenced for the publication of this data paper. The collection contains a total of 522 taxa, including 161 species and 361 subspecies. Two species are classified by the IUCN Red List as Endangered - the wattled crane (Grus carunculata) and the Gabela bush-shrike (Laniarius amboimensis) - and two are classified as vulnerable - African penguin (Spheniscus demersus) and the white-headed vulture (Trigonoceps occipitalis). The temporal span of the database ranges between 1943 and 1979, but 32% are from years 1958–1959, and 25% from years 1968–1969. The spatial coverage of the collection is uneven, with 2/3 of the records representing only four of the eighteen provinces of the country, namely Huíla, Moxico, Namibe and Cuanza Sul. It adds, however, valuable information for the Huíla area of the Angolan Scarp, which is probably a biodiversity hotspot of global conservation priority. Furthermore, this georeferenced database adds invaluable bird information to the GBIF network, for one of the countries with highest but less known biodiversity in Africa. PMID:24693221

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

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

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

    The bird collection of the Instituto de Investigação Cientítica Tropical (Lisbon, Portugal) holds 5598 preserved specimens (skins), mainly from Angola, Mozambique, Guinea-Bissau, São Tomé and Principe, and Cape Verde. The subset collection from Angola includes 1560 specimens, which were taxonomically revised and georeferenced for the publication of this data paper. The collection contains a total of 522 taxa, including 161 species and 361 subspecies. Two species are classified by the IUCN Red List as Endangered - the wattled crane (Grus carunculata) and the Gabela bush-shrike (Laniarius amboimensis) - and two are classified as vulnerable - African penguin (Spheniscus demersus) and the white-headed vulture (Trigonoceps occipitalis). The temporal span of the database ranges between 1943 and 1979, but 32% are from years 1958-1959, and 25% from years 1968-1969. The spatial coverage of the collection is uneven, with 2/3 of the records representing only four of the eighteen provinces of the country, namely Huíla, Moxico, Namibe and Cuanza Sul. It adds, however, valuable information for the Huíla area of the Angolan Scarp, which is probably a biodiversity hotspot of global conservation priority. Furthermore, this georeferenced database adds invaluable bird information to the GBIF network, for one of the countries with highest but less known biodiversity in Africa. PMID:24693221

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

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

    The concentrations of 3 oxides and 29 elements in 7 National Bureau of Standards (NBS) and 3 Instituto de Pesquisas Techno16gicas (IPT) reference clay samples were etermined by instrumental neutron activation analysis. The analytical work was designed to test the homogeneity of constituents in three new NBS reference clays, NBS-97b, NBS-98b, and NBS-679. The analyses of variance of 276 sets of data for these three standards show that the constituents are distributed homogeneously among bottles of samples for 94 percent of the sets of data. Three of the reference samples (NBS-97, NBS-97a, and NBS-97b) are flint clays; four of the samples (NBS-98, NBS-98a, NBS-98b, and IPT-32) are plastic clays, and three of the samples (NBS-679, IPT-28, and IPT-42) are miscellaneous clays (both sedimentary and residual). Seven clays are predominantly kaolinite; the other three clays contain illite and kaolinite in the approximate ratio 3:2. Seven clays contain quartz as the major nonclay mineral. The mineralogy of the flint and plastic clays from Missouri (NBS-97a and NBS-98a) differs markedly from that of the flint and plastic clays from Pennsylvania (NBS-97, NBS-97b, NBS-98, and NBS-98b). The flint clay NBS-97 has higher average chromium, hafnium, lithium, and zirconium contents than its replacement, reference sample NBS-97b. The differences between the plastic clay NBS-98 and its replacement, NBS-98b, are not as pronounced. The trace element contents of the flint and plastic clays from Missouri, NBS-97a and NBS-98a, differ significantly from those of the clays from Pennsylvania, especially the average rare earth element (REE) contents. The trace element contents of clay sample IPT-32 differ from those of the other plastic clays. IPT-28 and IPT-42 have some average trace element contents that differ not only between these two samples but also from all the other clays. IPT-28 has the highest summation of the average REE contents of the 10 samples. The uranium content of NBS-98a, 46

In this study, we describe the bird collection from the Democratic Republic of São Tomé and Príncipe, which was fully taxonomically checked and georeferenced. The IICT bird collection contains 5598 specimens, of which 559 are from São Tomé and Príncipe, representing 85 taxa, including 19 endemic species and 13 endemic subspecies of birds. The specimens were collected between 1946 and 1973, although 43% of the records are from 1954 and 45% are from 1970. The geographic distribution of samples covers the whole territory, with a higher number of records from São Tomé than from Príncipe. The districts with highest number of records are Pagué (equivalent to Príncipe Island), and Água Grande and Mé-Zochi on São Tomé. Despite the relatively low number of specimens per taxon, the importance of the collection is considerable due to the high number of endemic and threatened species represented. Furthermore, it adds valuable information to the GBIF network, especially for a country whose two islands are each an Endemic Bird Area and for which substantial gaps in ornithological knowledge remain.

    Background Osteoarthritis (OA) is one of the main causes of disability worldwide, especially in persons >55 years of age. Currently, controversy remains about the best therapeutic alternative for this disease when evaluated from a cost-effectiveness viewpoint. For Social Security Institutions in developing countries, it is very important to assess what drugs may decrease the subsequent use of medical care resources, considering their adverse events that are known to have a significant increase in medical care costs of patients with OA. Three treatment alternatives were compared: celecoxib (200 mg twice daily), non-selective NSAIDs (naproxen, 500 mg twice daily; diclofenac, 100 mg twice daily; and piroxicam, 20 mg/day) and acetaminophen, 1000 mg twice daily. The aim of this study was to identify the most cost-effective first-choice pharmacological treatment for the control of joint pain secondary to OA in patients treated at the Instituto Mexicano del Seguro Social (IMSS). Methods A cost-effectiveness assessment was carried out. A systematic review of the literature was performed to obtain transition probabilities. In order to evaluate analysis robustness, one-way and probabilistic sensitivity analyses were conducted. Estimations were done for a 6-month period. Results Treatment demonstrating the best cost-effectiveness results [lowest cost-effectiveness ratio $17.5 pesos/patient ($1.75 USD)] was celecoxib. According to the one-way sensitivity analysis, celecoxib would need to markedly decrease its effectiveness in order for it to not be the optimal treatment option. In the probabilistic analysis, both in the construction of the acceptability curves and in the estimation of net economic benefits, the most cost-effective option was celecoxib. Conclusion From a Mexican institutional perspective and probably in other Social Security Institutions in similar developing countries, the most cost-effective option for treatment of knee and/or hip OA would be celecoxib.

    The area of the Dunas da Joaquina, in Santa Catarina island, contains one of the most important remnants of restinga habitat in Santa Catarina State, southern Brazil. In December 2003, a fire occurred in a portion of this area, affecting most of the vegetation, including the bromeliad community. In this study, the density of individuals and the diet composition of the bromelicolous treefrog Scinax cf. alter were compared between the area affected by the fire and an adjacent unburned area. One-hundred-and-fifty-eight ground bromeliads (Vriesea friburguensis) were dissected and searched for the presence of treefrogs among their leaves. We found 30 frogs in 29.5% (23/78) of the bromeliads from the unburned site, with a mean of 1.3 frogs per rosette, and 15 frogs in 12.5% (10/80) of the bromeliads from the burned site, with a mean of 1.6 frogs per rosette. Eight (27%) of the frogs from the unburned site and eleven (73%) of those from the burned site had empty stomachs. Frogs from the burned site also contained less prey per stomach than those from the unburned site. The data suggest that the fire has negatively affected the local population of Scinax cf. alter, though it is possible that the population can recover.

    This is the first complete mitochondrial genome of a Tityus species, although it is the most medically important genus in South America. Tityus serrulatus (Brazilian yellow scorpion) mtDNA revealed the same gene arrangement of three out of four other mitogenomes published by now for the same family (Centruroides limpidus, Mesobuthus gibbosus, M. martensii and Buthus occitanus). However, it presented many unique characteristics such as possession of Cox1 gene, different from all other protein-coding genes of scorpion mtDNA, starts with an atypical start codon (CTG). Moreover, no tRNA gene have complete typical secondary structure and the Tytius genome presented three non-coding regions longer than 100bp. Also, it contains the smallest scorpion 16S gene reported by now. Phylogenetic analysis using concatenated homologous genes confirmed Buthidae as a monophyletic clade and supports a monophyletic group including T. serrulatus and the other American species, C. limpidus.

    The sand fly Lutzomyia longipalpis is the main vector of Leishmania (L.) infantum (Nicolle), the causative agent of American visceral leishmaniasis (AVL) in the New World. Male Lu. longipalpis have secretory glands which produce sex pheromones in either abdominal tergites 4 or 3 and 4. These glands are sites of sex pheromone production and each pheromone type may represent true sibling species. In Latin America, apart from Lu. pseudolongipalpis Arrivillaga and Feliciangeli from Venezuela, populations of Lu. longipalpis s.l. can be identified by their male-produced sex pheromones: (S)-9-methylgermacrene-B, 3-methyl-α-himachalene and the two cembrenes, 1 and 2. In this study, we present the results of a coupled gas chromatography - mass spectrometry analysis of the pheromones of males Lu. longipalpis captured in an endemic area of visceral leishmaniasis in Asunción, Paraguay. Our results show that Lu. longipalpis from this site produce (S)-9-methylgermacrene-B which has also been found in Lu. longipalpis from different areas of Brazil, Colombia and Central America.

    In October 1899, the bubonic plague arrived in Brazil through the port of Santos. A city of intensive port activity, Santos was the gateway for a plague epidemic that devastated several cities in Brazil in the early 20th century and prompted joint action by several states to fight it. More importantly, given the difficulties and delays in importing anti-plague serum from Europe, it led to the creation of the Butantan Institute in Sao Paulo (in 1899) and the Municipal Serotherapeutic Institute in Rio de Janeiro (in 1900), which developed and standardized anti-plague serum and vaccines according to the particular conditions of the country. Until then, public health efforts had been isolated and had not reached the whole country. Oswaldo Cruz, newly arrived after three years of specialization at the Pasteur Institute in Paris, worked with scientists Adolfo Lutz and Vital Brazil on identifying the plague in Santos. This article analyzes the arrival of the bubonic plague epidemic in the state of Sao Paulo and the public health measures taken to combat the disease and provide patient care in the early part of the 20th century. The primary sources for this analysis were the São Paulo newspapers, especially O Estado de Sao Paulo, and reports from the Ministry of Justice and the President of the State of Sao Paulo.

Formation of the Network was coordinated by the Essential Medicines, Vaccines, and Health Technologies Unit of the Pan American Health Organization, with the technical and financial support of the National Center for Microbiology of the Carlos III Health Institute (Spain), and the technical support of the Microbiology Department of the Dr. C. Malbrán National Institute on Infectious Diseases (Argentina) and the Microbiology Unit of the Parasitology Service of the Adolfo Lutz Institute (Brazil). The Network's principle objectives are epidemiological surveillance of invasive fungal infections through detection of antifungal resistance and identification of emergent, invasive fungal infections; establishment of norms and common protocols for early diagnosis of mycoses; and strengthening coordination, communications, and transference mechanisms among countries. The Network must be gradually implemented and must include staff training, a systematic process for sharing technology, evaluation of diagnostic techniques, identification of fungal species, and standardized tests for antifungal susceptibility.

Fish were collected from October 2007 to February 2009 using nylon monofilament gill nets and transported to the field laboratory where they were euthanized and the eyes were taken and examined under a stereomicroscope. Hypostomus ancistroides and M. parananus were not infected by this diplostomid. Hypostomus hermanni and H. margaritifer were represented by only one specimen but both had a high intensity of A. compactum metacercarie (27 and 35, respectively). Hypostomus strigaticeps (n = 45) and H. iheringii (n = 28) were the most representative specimens and the prevalence, mean intensity of infection and mean abundance were 24.4%, 10.3 and 2.7, and 64.2%, 13.1 and 8.4, respectively. No correlation was observed between the intensity of infection and the standard length (r = - 0.223; P = 0.827) and weight (r = 0.03; P = 0.779) of studied fish. Similarly, linear regression among these variables showed a poor correlation and indicated that the infection by A. compactum metacercariae occurs similarly in small and large fish specimens. A seasonal pattern of infection was not observed. Hypostomus hermanni, H. iheringii, H. margaritifer and H. strigaticeps were new hosts recorded for A. compactum metacercariae. A review of morphometric data of A. compactum metacercariae is presented.

    The life cycle of vectors and the reservoirs that participate in the chain of infectious diseases have a strong relationship with the environmental dynamics of the ecosystems in which they live. Oscillations in population abundance and seasonality of insects can be explained by factors inherent in each region and time period. Therefore, knowledge of the relationship and influence of environmental factors on the population of Lutzomyia longipalpis is necessary because of the high incidence of visceral leishmaniasis (VL) in Brazil. This study evaluates the influence of abiotic variables on the population density and seasonal behavior of L. longipalpis in an urban endemic area of VL in Brazil. The sand fly captures were performed every two months between November, 2009 and November, 2010 in the peridomicile of 13 randomly selected residences. We captured 1,367 specimens of L. longipalpis, and the ratio of male/female flies was 2.86:1. The comparison of the total male specimens in the two seasons showed a statistical difference in the wet season, but there was no significant difference when considering the total females. With respect to climatic variables, a significant negative association was observed only with wind speed. During periods of high wind speeds, the population density of this vector decreased. The presence of L. longipalpis was found in all months of the study with bimodal behavior and population peaks during the wet season.

    Amphibians are hosts for a wide variety of ecto- and endoparasites, such as protozoans and parasitic worms. Naididae is a family of Oligochaeta whose species live on a wide range of substrates, including mollusks, aquatic macrophytes, sponges, mosses, liverworts, and filamentous algae. However, some species are known as endoparasitic from vertebrates, such as Dero (Allodero) lutzi, which is parasitic of the urinary tracts of frogs, but also have a free-living stage. Specimens in the parasitic stage lack dorsal setae, branchial fossa, and gills. Here we report the occurrence of D. (A.) lutzi associated with anuran Scinax fuscovarius from Semi-deciduous Atlantic Rain Forest in southern Brazil. The study took place at the Caiuá Ecological Station, Diamante do Norte, Paraná, southern Brazil. Seven specimens of S. fuscovarius were examined for parasites but only one was infected. Parasites occurred in ureters and urinary bladder. Previous records of this D. (A.) lutzi include the Brazilian States of Santa Catarina, São Paulo, Rio de Janeiro, and Minas Gerais, as well as Cuba and North America. This is a new locality record for this species in Brazil. Reports of Dero (Allodero) lutzi are rare, due to difficulty of observation, and such events are restricted only the fortuitous cases. It is important to emphasize the necessity of future studies, which are fundamental to the understanding of biological and ecological aspects of this species. PMID:25945624

    The seasonal distribution of Lutzomyia longipalpis was studied in two forested and five domiciliary areas of the urban area of Campo Grande; MS, from December 2003 to November 2005. Weekly captures were carried out with CDC light traps positioned on ground and in the canopy inside a residual forest and on the edge (ground) of a woodland and in at least one of the following ecotopes in peridomiciles-a cultivated area, a chicken coop, a pigsty, a kennel, a goat and sheep shelter and an intradomicile. A total of 9519 sand flies were collected, 2666 during the first year and 6853 during the second. L. longipalpis was found throughout the 2-year period, presenting smaller peaks at intervals of 2-3 months and two greater peaks, the first in February and the second in April 2005, soon after periods of heavy rain. Only In one of the woodlands was a significant negative correlation (p<0.05) between the number of insects and temperature during the first year and the climatic factors (temperature, RHA and rain) was observed. In the domiciliary areas in four domiciles some positive correlations (p< or =0.05) occurred in relation to one or more climatic factors; however, the species shows a clear tendency to greater frequency (72%) in the rainy season than in the dry (28%). Thus, we recommend an intensification of the VL control measures applied in Campo Grande, MS, during the rainy season with a view to reducing the risk of the transmission of the disease.

    Nutrient digestion and absorption after blood feeding are important events for Lutzomyia longipalpis, which uses these nutrients to produce eggs. In this context, the pH inside the digestive tract is an important physiological feature as it can markedly influence the digestive process as well as interfere with Leishmania development in infected phlebotomines. It was described previously that unfed females have an acidic midgut (pH 6). In this study, the pH inside the midgut of blood-fed females was measured. The abdominal midgut (AM) pH varied from 8.15+/-0.31 in the first 10 h post-blood meal to 7.7+/-0.17 after 24 h. While the AM was alkaline during blood digestion, the pH in the thoracic midgut (TM) remained acidic (5.5-6.0). In agreement with these findings, the enzyme alpha-glucosidase, which has an optimum pH of 5.8, is mainly encountered in the acidic TM. The capacity of unfed females to maintain the acidic intestinal pH was also evaluated. Our results showed the presence of an efficient mechanism that maintains the pH almost constant at about 6 in the midgut, but not in the crop. This mechanism is promptly interrupted in the AM by blood ingestion. RT-PCR results indicated the presence of carbonic anhydrase in the midgut cells, which apparently is required to maintain the pH at 6 in the midgut of unfed females. Investigations on the phenomenon of alkalization observed after blood ingestion indicated that two mechanisms are involved: in addition to the alkalization promoted by CO2 volatilization there is a minor contribution from a second mechanism not yet characterized. Some inferences concerning Leishmania development and pH in the digestive tube are presented.

    São Paulo is the most populous Brazilian state and reports the largest number of tuberculosis cases in the country annually (over 18,500). This study included 193 isolates obtained during the 2nd Nationwide Survey on Mycobacterium tuberculosis Drug Resistance that was conducted in São Paulo state and 547 isolates from a laboratory based study of drug resistance that were analyzed by the Mycobacteria Reference Laboratory at the Institute Adolfo Lutz. Both studies were conducted from 2006 to 2008 and sought to determine the genetic diversity and pattern of drug resistance of M. tuberculosis isolates (MTC) circulating in São Paulo. The patterns obtained from the spoligotyping analysis demonstrated that 51/740 (6.9%) of the isolates corresponded to orphan patterns and that 689 (93.1%) of the isolates distributed into 144 shared types, including 119 that matched a preexisting shared type in the SITVIT2 database and 25 that were new isolates. A total of 77/144 patterns corresponded to unique isolates, while the remaining 67 corresponded to clustered patterns (n = 612 isolates clustered into groups of 2–84 isolates each). The evolutionarily ancient PGG1 lineages (Beijing, CAS1-DEL, EAI3-IND, and PINI2) were rarely detected in São Paulo and comprised only 13/740, or 1.76%, of the total isolates; all of the remaining 727/740, or 98.24%, of the MTC isolates from São Paulo state were from the recent PGG2/3 evolutionary isolates belonging to the LAM, T, S, X, and Haarlem lineages, i.e., the Euro-American group. This study provides the first overview of circulating genotypes of M. tuberculosis in São Paulo state and demonstrates that the clustered shared types containing seven or more M. tuberculosis isolates that are spread in São Paulo state included both resistant and susceptible isolates.

    Background Due to the growing number of outbreaks of infection in hospital nurseries, it becomes essential to set up a sanitation program that indicates that the appropriate chemical agent was chosen for application in the most effective way. Method For the purpose of evaluating the efficacy of a chemical agent, the minimum inhibitory concentration (MIC) was reached by the classic method of successive broth dilutions. The reference bacteria utilized were Bacillus subtilis var. globigii ATCC 9372, Bacillus stearothermophilus ATCC 7953, Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923. The strains of Enterobacter cloacae IAL 1976 (Adolfo Lutz Institute), Serratia marcescens IAL 1478 and Acinetobactev calcoaceticus IAL 124 (ATCC 19606), were isolated from material collected from babies involved in outbreaks of infection in hospital nurseries. Results The MIC intervals, which reduced bacteria populations over 08 log10, were: 59 to 156 mg/L of quaternarium ammonium compounds (QACs); 63 to 10000 mg/L of chlorhexidine digluconate; 1375 to 3250 mg/L of glutaraldehyde; 39 to 246 mg/L of formaldehyde; 43750 to 87500 mg/L of isopropanol or ethanol; 1250 to 6250 mg/L of iodine in polyvinyl-pyrolidone complexes, 150 to 4491 mg/L of chlorine-releasing-agents (CRAs); 469 to 2500 mg/L of hydrogen peroxide; and, 2310 to 18500 mg/L of peracetic acid. Conclusions Chlorhexidine showed non inhibitory activity over germinating spores. A. calcoaceticus, was observed to show resistance to the majority of the agents tested, followed by E. cloacae and S. marcescens. PMID:11591223

    Introducción: dado que el pronóstico de infarto del miocardio con elevación del segmento ST (IMCEST) depende de su manejo inmediato y de las medidas de prevención secundaria, el no seguir las recomendaciones actuales impide mejorar las expectativas de la población afectada por este padecimiento. El objetivo es describir el perfil clínico-epidemiológico y el proceso de atención del IMCEST en un hospital de tercer nivel. Métodos: se analiza la información clínica, la estratificación de riesgo, la terapia de revascularización y los hábitos de prescripción al egreso de los casos con IMCEST atendidos en un año. Resultados: se incluyeron 246 pacientes con edad promedio de 61 años; el 76 % fueron varones. La mayoría (37.3 %) de IMCEST ocurrió entre los 60 y los 69 años. El sedentarismo fue el factor de riesgo predominante. El 81.7 % de los casos tuvo score TIMI de riesgo bajo. El 35 % tuvo isquemia/viabilidad y en todos los cateterizados se demostraron obstrucciones coronarias. El 76 % se revascularizó con stent, principalmente farmacológico (77.5 %). Al egreso más del 90 % de los casos recibió estatina y antiplaquetarios, mientras otras drogas se prescribieron al 64-82 % de los casos. Conclusiones: el IMCEST predomina en hombres sedentarios de la séptima década. Estratificar el riesgo, buscar isquemia/viabilidad residual y revascularizar con stent farmacológico son prácticas comunes; el cumplimiento de recomendaciones basadas en la evidencia es mejor que en el pasado, pero todavía no es óptimo.

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

    Introducción: la razón de muerte materna (RMM) ha disminuido lentamente, no obstante que la OMS se propuso reducirla en un 75 % en el período de 1990 a 2015. Por esto es necesario continuar con el análisis de las causas para reforzar e innovar líneas de acción y así disminuir las muertes maternas en nuestro país. Métodos: estudio retrospectivo en el que se incluyeron casos de muerte materna que ocurrieron de 2009 a 2012, por causa directa e indirecta. La información se obtuvo del expediente de muerte materna, el cual es un documento oficial del IMSS. La definición de muerte materna utilizada fue la emitida por la OMS. Las muertes indirectas se agruparon según la décima revisión de la Clasificación Internacional de Enfermedades (CIE-10). Se utilizó estadística descriptiva. Resultados: la RMM en el IMSS ha disminuido en forma lenta pero constante, pues en el 2012 se obtuvo la RMM más baja en la institución (26.4). Sin embargo, la preeclampsia severa-eclampsia y la hemorragia obstétrica ocuparon el primero y segundo lugar. Como causa indirecta, las enfermedades del sistema cardiovascular, y las neoplasias malignas ocuparon los primeros lugares sin subestimar las cifras de las patologías respiratorias, digestivas y endocrinas. Conclusiones: es necesario proseguir con los esfuerzos para disminuir la RMM en todos los niveles de atención médica. Es prioritario continuar con la educación y consejería preconcepcional a mujeres en edad fértil y fortalecer las acciones en la planificación familiar.

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

    We present the new system for the evaluation of the medical specialization courses at the IMSS which will substitute in 2005 the one used at present. This system derives from a participative conception of education and has as an axis the development of aptitudes. For participative education, knowledge is the result of the student's elaboration, and not the result of the consumption of information. An aptitude is the conjunction of knowledge, abilities and attitudes in a constant development which gives the bearer experience a growing penetration to understand the problematic situations that challenge him, a greater reach of the decisions and actions performed and progressive pertinence to positively influence the working environment. The new evaluation system is centered in the development of two types of aptitude: the clinical aptitude and the aptitude for the appropriate use of information sources. It has an explanatory and instructions section, as well as four types of forms: (a) evaluation of the aptitudes development through time. (b) Performance of activities (in the service and academic) related with the aptitudes seeking to develop. (c) Evaluation of the academic and working environment, and (d) self evaluation. With the new system of evaluation of the formation of medical specialists we pretend to contribute to the overcoming of the educative labors at the Institute, by orienting the professors' and students' reflection towards the main aspects of learning, as well as promote the criticism and self-criticism.

    The advance in the knowledge and technology is growing quickly and greater quantity, so it is difficult for the health professional to access to whole information that is generated every day on diagnostic and therapeutic strategies more effective, so the clinic practice guidelines (CPG) is a resource to support the updating of the health professional and support them in making clinical decisions. The CPG is also a better support to the manager of health services in making decisions regarding the strategies that have performed for the patient and less risk to the individual and collective health. They also support the response capacity of the medical units and hospitals and guide the planning of services to the optimization of the resources. This paper summarizes the methodology of a national project for the development of GPC coordinated by the Mexican Social Security Institute with the collaboration of more than 1200 health professionals of the institution in a great effort institutional update and make information accessible to the entire health sector, which also defines the steps to upgrade and maintain the updating of knowledge and technology expressed in them.

    The epidemiologic transition moves mortality towards the chronic diseases as the main causes and the elderly groups as their main targets. The Institute Mexican del Seguro Social (IMSS) contributes with 3 of every 10 deaths reported in the country. Mortality rates in men increased from 330.1 x 100,000 in 1990 to 485.4 in 2005. In women rates grew from 249.9 to 405.5 in the same period. Mortality patterns show a mayor contribution by the northern region and are different with regard to sex and age groups. The group under 20 years old have a lower contribution to mortality during the period studied. In the population insured by IMSS, the 60 to 79 age group in both sexes contributes with a major proportion of deaths.

    Purpose To report the outcomes on the Boston Type 1 Keratoprosthesis at our institution. Design Retrospective analysis case series. Participants We analyzed 54 eyes of 53 patients who previously underwent Boston Type 1 Keratoprosthesis surgery at our institution from July 2006 to March 2011. Methods Preoperative and postoperative parameters were collected and analyzed. Main outcome measures Visual acuity and keratoprosthesis stability. Results Common preoperative diagnoses were penetrating keratoplasty failure in 49 eyes (90.7%), chronic keratitis in 2 eyes (3.7%), ocular cicatricial pemphigoid in 1 eye (1.85%), Stevens Johnson syndrome in 1 eye (1.85%) and corneal vascularization in 1 eye (1.85%). Additionally, 40 eyes (74%) had preoperative glaucoma, and an Ahmed valve was implanted in 55% of them. Preoperative BCVA ranged from 20/200 to light perception. At an average follow-up of 20.15 months ± 12.7 (range, 1–56), postoperative vision improved to ⩾20/200 in 18 eyes (33.3%) and ⩾20/50 in 4 eyes (7.4%). The graft retention was 96%. Conclusions The Boston Type 1 keratoprosthesis is a valid option for high-risk patients. The design improvements in the Boston keratoprosthesis, as well as the daily implementation of the therapeutic methods, have notably diminished occurrence of the most serious complications, such as corneal necrosis and endophthalmitis. As such, glaucoma and its subsequent complications now stand as the most prevalent prognostic factor in the long term. PMID:23960937

    Introducción: las células troncales hematopoyéticas se han empleado por más de 50 años en el tratamiento de diversas enfermedades. La sangre de cordón umbilical es una fuente viable de células troncales hematopoyéticas con fines de trasplante. El objetivo es informar la aportación clínica del banco de células de cordón umbilical (BCCU) en el tratamiento de diversas enfermedades.Métodos: desde 2005 a la fecha se analizó el número de unidades de sangre de cordón umbilical (SCU) y su empleo para el trasplante en diversas enfermedades. Se seleccionaron donadoras embarazadas voluntarias en trabajo de parto de quienes se recolectó SCU, la cual fue sometida a su procesamiento, criopreservación y validación, así como a estudios de compatibilidad previo a su uso para trasplante.Resultados: se evaluaron 10 099 candidatas a donación, de quienes se recolectaron 2481 unidades de SCU, de estas se procesaron y criopreservaron 893 unidades para trasplante. En 65 % de los casos hubo histocompatibilidad entre las células de cordón y el receptor. Se trasplantaron 87 pacientes (67 % neoplasias hematológicas), que recibieron 140 unidades SCU en 102 trasplantes.Conclusiones: nuestro Banco de CCU ha logrado desarrollar una línea celular (troncales hematopoyéticas) con estándares de calidad internacionales, y ha beneficiado a pacientes con necesidad de un trasplante, en especial los padecimientos oncohematológicos.

    Extrinsic allergic alveolitis is an interstitial lung disease caused by exposure to a variety of inhaled antigens. In Mexico, the most frequent form is due to the inhalation of avian antigens, markedly pigeon proteins. Depending on type and time exposure, the disease presents different clinical forms usually characterized by progressive dyspnea, ground glass or reticulonodular images on chest x rays, a restrictive functional pattern, rest hypoxemia worsening with exercise, and increase of T lymphocytes in bronchoalveolar lavage with an inversion in the helper/suppressor ratio. In this paper, we discuss a 15-year experience with this pathological problem in Mexico, emphasizing the differences with this disorder in Caucasian populations. Generally, our patients display a chronic form of the disease, which evolves to fibrosis in about one-half of the patients. In this sense, the diagnostic, prognostic, and therapeutic focusing exhibit different elements, and thus the development of clinical and basic research is strongly required.

    Leptodactylus macrosternum and L. vastus (family: Leptodactylidae) are commonly encountered in the “Caatinga” biome in northern Brazil. The body fat of L. vastus is used as a zootherapeutic for treating a number of human maladies. The aim of this work was to determine the chemical composition of the body fats of L. macrosternum and L. vastus and to evaluate their antimicrobial activities as well as the ecological implications of their use in traditional folk medicine. Oils were extracted from body fat located in the ventral region of L. macrosternum (OLM) and L. vastus (OLV) using hexane as a solvent. The fatty acids were identified by GC-MS. The antimicrobial activities of the oils, either alone or in combination with antibiotics and antifungal drugs, were tested on standard strains of microorganisms as well as on multiresistant strains of Escherichia coli and Staphylococcus. OLM contained 40% saturated and 60% unsaturated fatty acids, while OLV contained 58.33% saturated and 41.67% unsaturated fatty acids. Our results indicated that both OLM and OLV demonstrated relevant antimicrobial activities (with MIC 256 μg/mL for both) against Pseudomonas aeruginosa and Candida krusei. However, no antimicrobial effects were observed when these oils were combined with antibiotics or antifungal drugs. PMID:23710241

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

The illness, as a sign of family imbalance within the humanistic concept, acquires an even if the treatment is given to the marital couple, the adolescent or the child. Family therapy helps in marital disagreements, behavior problems, anorexia, reactive depression, drug addictions, alcoholism and many other problems. The ISSSTE population has a stable location and is more or less homogeneous; in it family therapy is stimulating and possible; even though the institution imposes certain limitations to family therapy, the enthusiasm for this therapeutic method prevails.

    Stress, is considered to be a bodily response to both internal and environmental stimuli, is a live and unavoidable energy. It is important and necessary to learn to use it beneficially. In order to determine the utility of the educational program. "The use use and control of stress", a quasi-experimental study was conducted in 1993, in which 39 voluntary Zone I General Hospital (IMSS Tlaxcala State Delegation) workers were selected, based on stress levels over 3 points as found in an institutional validated to measure the stress level. Five groups were set up, and eight weekly educative interventions, composed of cognitive contents including stress, relaxation techniques, and techniques for living of 90 minutes each were attended by the members of these groups, utilizing groups dynamics. The results were analyzed in simple absolute and relative frequencies, as well as by Student's t tests. They show a reduction stress levels in 94.8% of the participants, which represents a 69.1% general gain, with p = < 0.005. The conclusion is that learning related with the use and control of stress is an alternative to improve the mental health of the individual and as concerns the work environment, to modify attitude of the IMSS worker.

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

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

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

Métodos: se estudiaron los pacientes que ingresaron al Servicio de Urgencias con diagnóstico de choque séptico y a quienes se les determinó lactato sérico al ingreso durante el periodo que abarca de enero a diciembre de 2013; se trató de un estudio de casos y controles. El valor de corte del lactato sérico asociado a mortalidad se realizó con las curvas ROC (del inglés receiver operating characteristic: característica operativa del receptor). Resultados: se estudiaron 67 pacientes del mes de enero al mes de diciembre del 2013. Sobrevivieron 56 (casos) y murieron 11 (controles). No hubo asociación con el género, la edad y las comorbilidades. El valor de corte para mortalidad del lactato sérico fue de 4.9 mmol/L. Fallecieron 10 de 40 pacientes con niveles de lactato > 4.9 mmol/L en comparación con solo uno de 27, con < 4.9 mmol/L, (p = 0.04) y razón de momios de 8.7. La mortalidad con valores de lactato > 4.9 mmol/L tuvo una sensibilidad de 90.9 % y una especificidad de 46.4 %. Conclusiones: los niveles de lactato sérico mayores a 4 mmol/L están asociados a un mayor riesgo de mortalidad en pacientes con choque séptico.

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

    Background Natural polyploidy has played an important role during the speciation and evolution of vertebrates, including anurans, with more than 55 described cases. The species of the Phyllomedusa burmeisteri group are mostly characterized by having 26 chromosomes, but a karyotype with 52 chromosomes was described in P. tetraploidea. This species was found in sintopy with P. distincta in two localities of São Paulo State (Brazil), where triploid animals also occur, as consequence of natural hybridisation. We analyse the chromosomes of P. distincta, P. tetraploidea, and their triploid hybrids, to enlighten the origin of polyploidy and to obtain some evidence on diploidisation of tetraploid karyotype. Results Phyllomedusa distincta was 2n = 2x = 26, whereas P. tetraploidea was 2n = 4x = 52, and the hybrid individuals was 2n = 3x = 39. In meiotic phases, bivalents were observed in the diploid males, whereas both bivalents and tetravalents were observed in the tetraploid males. Univalents, bivalents or trivalents; metaphase II cells carrying variable number of chromosomes; and spermatids were detected in the testis preparations of the triploid males, indicating that the triploids were not completely sterile. In natural and experimental conditions, the triploids cross with the parental species, producing abnormal egg clutches and tadpoles with malformations. The embryos and tadpoles exhibited intraindividual karyotype variability and all of the metaphases contained abnormal constitutions. Multiple NORs, detected by Ag-impregnation and FISH with an rDNA probe, were observed on chromosome 1 in the three karyotypic forms; and, additionally, on chromosome 9 in the diploids, mostly on chromosome 8 in the tetraploids, and on both chromosome 8 and 9 in the triploids. Nevertheless, NOR-bearing chromosome 9 was detected in the tetraploids, and chromosome 9 carried active or inactive NORs in the triploids. C-banding, base-specific fluorochrome stainings with CMA3 and DAPI, FISH with a telomeric probe, and BrdU incorporation in DNA showed nearly equivalent patterns in the karyotypes of P. distincta, P. tetraploidea, and the triploid hybrids. Conclusions All the used cytogenetic techniques have provided strong evidence that the process of diploidisation, an essential step for stabilising the selective advantages produced by polyploidisation, is under way in distinct quartets of the tetraploid karyotype.

    In May 1880, a royal decree signed by the Minister of the Interior, F. Romero Robledo, created the Institute of Operative Therapy under the gratuitous direction of Dr. Federico Rubio y Gali. Although it was located at the Hospital de la Princesa of Madrid, it was not dependent on the Institutions of Charity. According to the royal decree, major surgical procedures and specialized operative techniques would be performed at this Institute. Thus, the first teaching hospital was created in Spain, with operating rooms, dispensaries and polyclinics dedicated primarily to surgical specialties which were established at the Institute after 1880. The Institute's section for Diseases of the Urinary Tract, created in October 1885, was entrusted to the Madrid citizen Enrique Suender Rodríguez (1829-1897), the leading specialist in urology in our country at that time (his 100th death anniversary was commemorated last year) and whose assistant was Luis González Bravo y Serrano.

    Pioneering scientific information in underdeveloped areas poses several problems, such as (1) lack of understanding on the part of key functionaries as to the why, what, and when of information services; (2) lack of trained personnel to assume the responsibility for such services; (3) lack of economic resources; and (4) lack of information pertaining to available bibliographical sources in the particular area or region. The Bibliographic and Documentation Service of the Institute of Nutrition of Central America and Panama (INCAP) provides, in addition to the customary services, technical assistance for the organization or reorganization of biomedical libraries and makes INCAP library materials available to member countries, either by loan or photocopy. Although the program was designed for the member countries, INCAP tries to make its services available to other Latin American nations, Africa, and Asia, where similar nutritional problems are being studied.

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

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

  14. Overland Flow Generation and Soil Hydraulic Properties in Two Catchments in Central Panama

    Godsey, S.; Elsenbeer, H.; Stallard, R.

    2003-12-01

    Land management decisions in the Panama Canal watershed directly impact the hydrological functioning of the canal itself. Knowledge of the hydrological conditions in the forested portions of the watershed provides a baseline comparison for future land use changes. We chose to work on two streams on Barro Colorado Island that are representative of large regions of the watershed. These two streams respond differently to the same storm events: Conrad Trail Stream exhibits a fairly subdued and delayed response and Lutz Creek stream is flashier. In order to understand these differences, we investigated the soil saturated hydraulic conductivity (Ks) of the two catchments and studied the frequency of overland flow generation. The Ks measurements in dominant geologies in Lutz Creek as well as in Conrad Trail Stream are great enough at shallow depths (median Ks = 29.7, 65.6 and 38.3 mm/hr) that Hortonian overland flow is rare, but a marked decrease in Ks in Lutz Creek catchment at 30 cm (to 1.4 and 5.8 mm/hr) indicates that a perched water table leading to saturated overland flow is the likely runoff mechanism in Lutz Creek. In Conrad, Ks does not decrease as markedly with soil depth, and a perched water table would form at about 60 cm below the surface (median Ks = 0.7 mm/hr). Therefore, more water is able to infiltrate into the soil in Conrad Trail Stream and saturated overland flow is less common. Overland flow was generated much more frequently in Lutz Creek than in Conrad Trail Stream, with lower thresholds of storm magnitude, duration, antecedent wetness and intensity required to generate overland flow. We also quantified the importance of microtopographic features such as concentrated flow lines and the results have implications for experimental design at other field sites. The Lutz Creek and Conrad Trail stream information will provide a useful baseline for land management decisions.

    Black flies (Simuliidae) are considered to be pests in rural and in some urban areas in the south of Brazil due to the bites of females. Little information exists on the factors that contribute to Simuliidae distribution in these areas. We sampled 39 streams in the state of Rio Grande do Sul in September 2004 to address ecological aspects. Of the 18 species collected, those that occurred in more than 50% of the streams were: Simulium subnigrum Lutz 1910, Simulium pertinax Kollar 1882, Simulium subpallidum Lutz 1910 and Simulium incrustatum Lutz 1910. Species richness was not influenced by any of the environmental or geographical variables considered, and there was no pattern of species co-occurrence, corroborating the hypothesis of a stochastic distribution of the Simuliidae assemblage. When analyzed individually, only three of seven species with occurrence frequency >30% were related to any of the variables measured. The probabilities of occurrence of Simulium jujuyense Paterson & Shannon 1927 and S. pertinax were higher in streams with high values of water pH and electrical conductivity, whereas the opposite was observed for S. incrustatum. Therefore, due to stochastic distribution, the population studies of Simuliidae are more suitable for predicting the occurrence of species in rural areas than are studies of assemblages.

    Purpose: To automate routine imaging QA procedures so that complying with TG 142 and TG 179 can be efficient and reliable. Methods: Two QA tests for a True Beam Linac were automatized. A Winston Lutz test as described by Lutz et al{sup 1} using the Winston Lutz test kit from BrainLab, Germany and a CBCT Image Quality test as described in TG 179 using the EMMA phantom, Siemens Medical Physics, Germany were performed in our True Beam. For each QA procedure tested, a 3 step paradigm was used. First, the data was automatically acquired using True Beam Developer Mode and XML scripting. Second, the data acquired in the first step was automatically processed using in-home grown Matlab GUIs. Third, Machine Learning algorithms were used to automatically classify the processed data and reports generated. Results: The Winston Luzt test could be performed by an experienced medical physicist in 29.0 ± 8.0 min. The same test, if automated using our paradigm, could be performed in 3.0 ± 0.1 min. In the same lieu, time could be substantially saved for image quality tests. In this case, the amount of time saved will depend on the phantoms used and the initial localization method. Additionally, machine learning algorithms could automatically identify the roots of the problems if any and possibly help reduce machine down time. Conclusion: Modern linear accelerators are equipped with advanced 2D and 3D imaging that are used for patient alignment substantially improving IGRT protocols. However, this extra complexity exponentially increases the number of QA tests needed. Using the new paradigm described above, not only bare minimum but best practice QA programs could be implemented with the same manpower. This work is supported by Varian, Palo Alto, CA.

  2. Overland flow generation in two lithologically distinct rainforest catchments

    Streams on uniformly rainforest-covered, but lithologically very diverse Barro Colorado Island in central Panama?? show remarkable differences in their runoff response to rainfall. This lithological diversity is reflected in equally diverse soilscapes, and our objective was to test the hypothesis that contrasting runoff responses derive from soilscape features that control the generation of overland flow. We determined the soil saturated hydraulic conductivity (Ks) of two neighboring, but hydrologically contrasting catchments (Lutz Creek with a flashy and Conrad Trail with a delayed response to rainfall), and quantified the spatial and temporal frequency of overland flow occurrence. The median Ks values at a depth of 12.5 cm are large enough to rule out Hortonian overland flow, but a marked decrease in K s in Lutz Creek catchment at 30 cm suggests the formation of a perched water table and the generation saturation overland flow; the decrease in Ks in the Conrad Trail catchment is more gradual, and a perched water table is expected to form only at depths below 50 cm. In Lutz Creek, overland flow was generated frequently in time and space and regardless of topographic position, including near the interfluve, with very low thresholds of storm magnitude, duration, intensity and antecedent wetness, whereas in Conrad Trail, overland flow was generated much less frequently and then only locally. We conclude that soilscape features and microtopography are important controls of overland flow generation in these catchments. Our results contribute to the growing evidence that overland flow and forests are not a priori a contradiction in terms. ?? 2004 Elsevier B.V. All rights reserved.

    Terrestrial and near-earth measurements are examined in order to investigate possible solar wind sources for the sudden global brightenings noted in Comet IRAS-Araki-Alcock. These brightenings are not found to be associated with increases in the solar wind momentum flux, quantity of solar energetic particles, or solar activity, in contradiction to the proposal of Lutz and Wagner (1986). If a radial alignment of the IMF seen at IMP-8 after about 0800 UT was not responsible for the cometary brightening, then it is suggested that the brightening must have been intrinsic to the comet.

    The technique to generate transgenic mosquitoes requires adaptation for each target species because of aspects related to species biology, sensitivity to manipulation and rearing conditions. Here we tested different parameters on the microinjection procedure in order to obtain a transgenic Neotropical mosquito species. By using a transposon-based strategy we were able to successfully transform Aedes fluviatilis (Lutz), which can be used as an avian malaria model. These results demonstrate the usefulness of the piggyBac transposable element as a transformation vector for Neotropical mosquito species and opens up new research frontiers for South American mosquito vectors.

    Dendropsophus branneri is a small treefrog largely distributed throughout the Tropical Atlantic and Caatinga morphoclimatic domains (see Ab'Sáber 1977 for morphoclimatic domains), from northeastern to southeastern Brazil [Lutz 1973, Frost 2014; see Zina et al. 2014 for taxonomic comments on D. minusculus (Rivero, 1971) and D. branneri]. This species is currently placed in the D. microcephalus species group according to Bastos & Pombal (1996) and Faivovich et al. (2005). The D. microcephalus group comprises 36 species (Frost 2014), 14 of which have known tadpoles. Here, we describe the external morphology and color patterns of the previously unknown tadpole of D. branneri. PMID:25947693

  18. Emerging magnetic stability in atomically assembled spin arrays

    2012-02-01

    Magnetic stability is usually created by the interaction of a large ensemble of atomically small magnetic moments that are themselves unstable. We make use of the Scanning Tunneling Microscope's ability to move individual atoms and construct arrays of interacting spins. Owed to their smallness, the magnetic states of these spin arrays are quantized and we probe their energies by inelastic electron tunneling spectroscopy [1]. To gain access to the equally important dynamical properties we employ an all-electronic pump-probe measurement scheme with which we follow the evolution between the spin states at nanosecond speed [2]. The combination of energetic and dynamical information allows identification of the relevant spin interaction and spin relaxation mechanisms at the atomic level. We design arrangements of atoms that suppress quantum tunneling of magnetization and drastically stabilize different spin configurations. Tracing the emergence of magnetic stability in the progression from individual atoms to arrays of spins points to new avenues for spintronic applications at atomic dimensions. [4pt] [1] A. J.

    In this work, the survey of simuliid species and the study of their spatial distribution in four streams of a small watershed situated in Londrina, Paraná State, were carried out from January to October 2007. Changes in the species composition of the breeding sites were also checked along the sampling months. Seventeen black fly species were found, being Simulium botulibranchium Lutz, Simulium travassosi d'Andretta & d'Andretta, Simulium anamariae Vulcano, Simulium brachycladum Lutz & Pinto and Simulium metallicum s. l. Bellardi new records for Paraná State. The Canonical Correspondence Analysis showed that the environmental variables most correlated to the species distribution among sample sites were water conductivity and those linked to physical dimensions of the breeding sites, like width, depth and water velocity. The matrix of faunistic similarity among collecting dates was negatively correlated to the time interval of sampling matrix for three of the water bodies studied, showing the existence of temporal changes in the species composition. According to Multiple Regression Analysis, temporal abundance variation of Simulium perflavum Roubaud, Simulium inaequale Paterson & Shannon and Simulium lutzianum s. l. Pinto was not linked to air temperature, photoperiod and rainfall, suggesting the influence of other factors, probably those directly associated to specific breeding site conditions. The results indicate that differences in physical and chemical characteristics among water bodies may affect the taxonomic composition of simuliids in this watershed. PMID:20498969

  2. Identifying storm flow pathways in a rainforest catchment using hydrological and geochemical modelling

    2004-01-01

    The hydrological model TOPMODEL is used to assess the water balance and describe flow paths for the 9??73 ha Lutz Creek Catchment in Central Panama. Monte Carlo results are evaluated based on their fit to the observed hydrograph, catchment-averaged soil moisture and stream chemistry. TOPMODEL, with a direct-flow mechanism that is intended to route water through rapid shallow-soil flow, matched observed chemistry and discharge better than the basic version of TOPMODEL and provided a reasonable fit to observed soil moisture and wet-season discharge at both 15-min and daily time-steps. The improvement of simulations with the implementation of a direct-flow component indicates that a storm flow path not represented in the original version of TOPMODEL plays a primary role in the response of Lutz Creek Catchment. This flow path may be consistent with the active and abundant pipeflow that is observed or delayed saturation overland flow. The 'best-accepted' simulations from 1991 to 1997 indicate that around 41% of precipitation becomes direct flow and around 10% is saturation overland flow. Other field observations are needed to constrain evaporative and groundwater losses in the model and to characterize chemical end-members posited in this paper.

    2014-06-01

    Purpose: To quantify the sub millimeter overall accuracy of EDGETM, the dedicated linac based SRS/SABR treatment platform from Varian, using a novel End-to-End (E2E) test phantom. Methods: The new E2E test phantom developed by Varian consists of a cube with an outer dimension of 15x15x15 cm3. The phantom is equipped with an exchangable inner cube (7×7×7 cm3) to hold radiochromic films or a tungsten ball (diameter = 5 mm) for Winston-Lutz tests. 16 ceramic balls (diameter = 5 mm) are embedded in the outer cube. Three embedded Calypso transponders allow for Calypso based monitoring. The outer surface of the phantom is tracked using the Optical Surface Monitoring System (OSMS). The phantom is positioned using kV, MV and CBCT images. A simCT of the phantom was acquired and SRS/SABR plans were treated using the new phantom on the first clinical installed EDGETM. As a first step a series of EPID based Winston-Lutz tests have been performed. As a second step the calculated dose distribution applied to the phantom was verified with radiochromic films in orthogonal planes. The measured dose distribution is compared with the calculated (Eclipse) one based on the known isocenter on both dose distributions. The geometrical shift needed to match both dose distributions is the overall accuracy and is determined using dose profiles, isodose lines or gamma pass rates (3%, 1 mm). Results: Winston-Lutz tests using the central tungsten BB demonstrated a targeting accuracy of 0.44±0.18mm for jaw (2cm × 2cm) defined 0.39±0.19mm for MLC (2cm × 2cm) defined and 0.37±0.15mm for cone (12.5 mm) defined fields. A treated patient plan (spinal metastases lesion with integrated boost) showed a dosimetric dose localization accuracy of 0.6mm. Conclusion: Geometric and dosimetric E2E tests on EDGETM, show sub-millimeter E2E targeting and dose localisation accuracy.

    2015-06-15

    Purpose To implement and evaluate an image-based Winston-Lutz (WL) test to measure the displacement between ExacTrac imaging origin and radiation isocenter on a Novalis Tx system using RIT V6.2 software analysis tools. Displacement between imaging and radiation isocenters was tracked over time. The method was applied for cone-based and MLC-based WL tests. Methods The Brainlab Winston-Lutz phantom was aligned to room lasers. The ExacTrac imaging system was then used to detect the Winston- Lutz phantom and obtain the displacement between the center of the phantom and the imaging origin. EPID images of the phantom were obtained at various gantry and couch angles and analyzed with RIT calculating the phantom center to radiation isocenter displacement. The RIT and Exactrac displacements were combined to calculate the displacement between imaging origin and radiation isocenter. Results were tracked over time. Results Mean displacements between ExacTrac origin and radiation isocenter were: VRT: −0.1mm ± 0.3mm, LNG: 0.5mm ± 0.2mm, LAT: 0.2mm ± 0.2mm (vector magnitude of 0.7 ± 0.2mm). Radiation isocenter was characterized by the mean of the standard deviations of the WL phantom displacements: σVRT: 0.2mm, σLNG: 0.4mm, σLAT: 0.6mm. The linac couch base was serviced to reduce couch walkout. This reduced σLAT to 0.2mm. These measurements established a new baseline of radiation isocenter-imaging origin coincidence. Conclusion The image-based WL test has ensured submillimeter localization accuracy using the ExacTrac imaging system. Standard deviations of ExacTrac-radiation isocenter displacements indicate that average agreement within 0.3mm is possible in each axis. This WL test is a departure from the tradiational WL in that imaging origin/radiation isocenter agreement is the end goal not lasers/radiation isocenter.

    2014-06-01

    Purpose: The Mevion proton therapy machine is the first to feature a gantry mounted sychro-cyclotron. In addition, the system utilizes a 6D motion couch and kV imaging for precise proton therapy. To quantify coincidence between these systems, isocentricity tests were performed based on kV imaging alignment using radiochromic film. Methods: The 100 ton gantry and 6D robotic couch can rotate 190° around isocenter to provide necessary beam angles for treatment. The kV sources and detector panels are deployed as needed to acquire orthogonal portals. Gantry and couch mechanical isocenter were tested using star-shots and radiochromic-film (RCF). Using kV imaging, the star-shot phantom was aligned to an embedded fiducial and the isocenter was marked on RCF with a pinprick. The couch and gantry stars were performed by irradiating films at every 45° and 30°, respectively. A proton beam with a range and modulation-width of 18 cm was used. A Winston-Lutz test was also performed at the same gantry and couch rotations using a custom jig holding RCF and a tungsten ball placed at isocenter. A 2 cm diameter circular aperture was used for the irradiation. Results: The couch star-shot indicated a minimum tangent circle of 0.6 mm, with a 0.9 mm offset from the manually marked isocenter. The gantry star-shot showed a 0.6 mm minimum tangent circle with a 0.5 mm offset from the pinprick. The Winston Lutz test performed for gantry rotation showed a maximum deviation from center of 0.5 mm. Conclusion: Based on star-shots and Winston-Lutz tests, the proton gantry and 6D couch isocentricity are within 1 mm. In this study, we have shown that the methods commonly utilized for Linac characterization can be applied to proton therapy. This revolutionary proton therapy system possesses excellent agreement between the mechanical and radiation isocenter, providing highly precise treatment.

    The effects of azadirachtin A added to the sucrose diet of the adult females on the mortality, oviposition, and hatching of the sand fly vector of American visceral leishmaniasis Lutzomyia longipalpis (Lutz & Neiva, 1912) were investigated. Concentrations of 0.1, 1.0, and 10.0 microg/mg of azadirachtin significantly increased insect mortality in comparison with control insects. The same dose also significantly reduced oviposition but not hatching. After a long development period, significantly fewer adult insects were obtained from eggs hatching by azadirachtin-treated females in a dose-response manner. These results indicate that azadirachtin is a potent sterilizer that could be used against the development of Lu. longipalpis populations and as a tool for studying physiological and biochemical processes in phlebotomine species.

    The sandfly Lutzomyia longipalpis (Lutz and Neiva, 1912) is the main vector of American Visceral Leishmaniasis. In spite of its medical importance and several studies concerning adult digestive physiology, biochemistry and molecular biology, very few studies have been carried out to elucidate the digestion in sandfly larvae. Even the breeding sites and food sources of these animals in the field are largely uncharacterized. In this paper, we describe and characterize several carbohydrases from the gut of L. longipalpis larvae, and show that they are probably not acquired from food. The enzyme profile of this insect is consistent with the digestion of fungal and bacterial cells, which were proved to be ingested by larvae under laboratory conditions. In this respect, sandfly larvae might have a detritivore habit in nature, being able to exploit microorganisms usually encountered in the detritus as a food source.

    2015-11-01

    Since the description of Lutzomyia longipalpis by Lutz and Neiva more than 100 years ago, much has been written in the scientific literature about this phlebotomine species. Soares and Turco (2003) and Lainson and Rangel (2005) have written extensive reviews focused on vector-host-parasite interactions and American visceral leishmaniasis ecology. However, during the last two decades, the success of Lu. longipalpis in colonising urban environments and its simultaneous geographical spreading have led to new theoretical and operational questions. Therefore, this review updates the general information about this species and notes the more challenging topics regarding the new scenario of urbanisation-spreading and its control in America. Here, we summarise the literature on these issues and the remaining unsolved questions, which pose recommendations for operational research.

  12. Focused attention, open monitoring and automatic self-transcending: Categories to organize meditations from Vedic, Buddhist and Chinese traditions.

    Travis, Fred; Shear, Jonathan

    2010-12-01

    This paper proposes a third meditation-category--automatic self-transcending--to extend the dichotomy of focused attention and open monitoring proposed by Lutz. Automatic self-transcending includes techniques designed to transcend their own activity. This contrasts with focused attention, which keeps attention focused on an object; and open monitoring, which keeps attention involved in the monitoring process. Each category was assigned EEG bands, based on reported brain patterns during mental tasks, and meditations were categorized based on their reported EEG. Focused attention, characterized by beta/gamma activity, included meditations from Tibetan Buddhist, Buddhist, and Chinese traditions. Open monitoring, characterized by theta activity, included meditations from Buddhist, Chinese, and Vedic traditions. Automatic self-transcending, characterized by alpha1 activity, included meditations from Vedic and Chinese traditions. Between categories, the included meditations differed in focus, subject/object relation, and procedures. These findings shed light on the common mistake of averaging meditations together to determine mechanisms or clinical effects.

    A new species of Petasiger inhabits Pelecanus occidentalis, from the Area de Conservación Guanacaste, Costa Rica. The new species most closely resembles Petasiger novemdecim Lutz 1929 and Petasiger caribbensis Nassi, 1980 by having 19 circumoral spines and vitelline follicles confluent between the ventral sucker and gonads. The new species differs from both of these species by having a cirrus sac that is anteroposteriorly elongate and that reaches posteriorly to the midventral sucker, an ovary and Mehlis' gland that overlap the anterior testis dorsally, a uterus that lies dorsal to the ventral sucker, and a dextromedial genital pore. In P. novemdecim and P. caribbensis the cirrus sac is round and does not extend posteriorly to the anterior margin of the ventral sucker, both the ovary and Mehlis' gland are anterior to the anterior testis, the uterus runs lateral to and not dorsal to the ventral sucker, and the genital pore opens medially and sinistromedially, respectively.

    In this study, we examined global treatment outcomes during 16 months of intensive, psychodynamic treatment for 77 inpatients suffering from treatment-refractory disorders. Hypotheses based on the phase model of treatment change (Howard, Lueger, Maling, & Martinovich, 1993; Howard, Moras, Brill, Martinovich, & Lutz, 1996) were supported in the study results. Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) Axis V scales assessing behavioral functioning demonstrated large and medium effect size change, whereas stable, enduring personality functioning assessed by psychoanalytic Rorschach scales and the Social Cognition and Object Relations Scale (Westen, 1995) for the Thematic Apperception Test (Murray, 1943) demonstrated small and medium effect size change. We also report assessment of reliable change index and clinical significance. The ecological validity of Rorschach measures is supported by significant validity coefficients (in the hypothesized directions) between implicit measures of personality functioning and behavioral ratings.

    Since the description of Lutzomyia longipalpis by Lutz and Neiva more than 100 years ago, much has been written in the scientific literature about this phlebotomine species. Soares and Turco (2003) and Lainson and Rangel (2005) have written extensive reviews focused on vector-host-parasite interactions and American visceral leishmaniasis ecology. However, during the last two decades, the success of Lu. longipalpis in colonising urban environments and its simultaneous geographical spreading have led to new theoretical and operational questions. Therefore, this review updates the general information about this species and notes the more challenging topics regarding the new scenario of urbanisation-spreading and its control in America. Here, we summarise the literature on these issues and the remaining unsolved questions, which pose recommendations for operational research. PMID:26517497

    The goal of this survey was to analyze the spatio-temporal distribution patterns of Culicoides Latreille species (Diptera: Ceratopogonidae) and their relationship with environmental variables in Salta, northwestern Argentina. Culicoides were collected monthly from January 2003 through December 2005. The influence of the climatic variables on population abundance was analyzed with a multilevel Poisson regression. A total of 918 specimens belonging to five species were collected. The most abundant species was Culicoides paraensis Goeldi (65.5%), followed by Culicoides lahillei Iches (14.6%) and Culicoides debilipalpis Lutz (7.6%). The highest seasonal abundance for C. paraensis, C. debilipalpis and C. lahillei occurred during the spring and summer. A Poisson regression analysis showed that the mean maximum and minimum temperature and the mean maximum and minimum humidity were the variables with the greatest influence on the population abundance of Culicoides species.

    The Steamboat Springs geothermal system provides the most dramatic example of subhorizontal thermal-fluid aquifers in crystalline rock in the Basin and Range, but this is by no means an isolated case. Similar but more diffuse subhorizontal permeability has been reported at Roosevelt Hot Springs and Cove-Fort Sulphurdale, Utah; and a km-scale gravity-slide block channels injectate at Dixie Valley, Nevada. During the course of this phase of the project 2543 reports including text, figures and large format enclosures, 1428 maps, and 698 well logs were scanned. The information is stored in a Microsoft Access Database on the Geothermal Server. Detailed geologic cross sections of the Desert Peak geothermal field were developed to identify the structural controls on the geothermal system and locate possible fluid flow paths. The results of this work were published by Lutz and others (2009, Appendix 1) in the Stanford Reservoir Engineering Conference Proceedings.

    Bertha Lutz was one of the women of her generation who enjoyed indisputable political and scientific authority. She wrote much and even more was written about her, especially during her day. The newspaper chronicles by Lima Barreto, countless letters, scientific papers, and unpublished texts by Bertha herself that are surveyed in this article indicate how much her feminism--inseparable from other dimensions of her life--fostered her professional career. Her feminism earned her a carefully constructed renown and visibility that interlocked with her professional performance. Science lent her social prestige and guaranteed legitimacy for her causes. During a period when the scientific community itself was engaged in publicizing its own activities, Bertha's feminist prominence in the media helped her make a name in the sciences. PMID:19397030

    The complete primary structures of toxin II-14 from the Mexican scorpion Centruroides noxius Hoffmann and toxin gamma from the Brazilian scorpion Tityus serrulatus Lutz and Mello have been determined. Cleavage of toxin gamma after Met-6 with CNBr produced the 55-residue peptide 7-61, which maintained the four disulphide bonds but was not toxic to mice at a dose 3 times the lethal dose of native toxin gamma. Pairwise comparison by metric analysis of segment 1-50 of toxin gamma and the corresponding segments from two other South American scorpion toxins, five North American scorpion toxins, nine North African scorpion toxins and one Central Asian scorpion toxin showed that the three Brazilian toxins are intermediate between the North American and North African toxins. This result is consistent with the hypothesis that the South American and African continents were joined by a land connection in the distant past. Images Fig. 1. PMID:4052021

    Lutz et al. (1976) have reported the first quantitative analyses of the strengths of the blue-green bands of methane which dominate the visible spectra of the outer planets. The present investigation represents an extension of the first study to include a number of bands between 6000 and 7500 A. The objective of this extension is to establish the validity of the scaled numerical curve of growth of the first study further into the saturated region and to test the apparent pressure independence of the high-overtone bands over a large pressure range. In addition, it is desired to provide a set of homogeneously determined band strengths and curves of growth over a large spectral region and over a large range of band strengths. This will make it possible to investigate feasible apparent dependences of planetary methane abundances on wavelength and band strength as a probe of the scattering processes in the planetary atmospheres.

    2010-01-01

    Advances in digital data acquisition, analysis, and storage have revolutionized the work in many biological disciplines such as genomics, molecular phylogenetics, and structural biology, but have not yet found satisfactory acceptance in morphology. Improvements in non-invasive imaging and three-dimensional visualization techniques, however, permit high-throughput analyses also of whole biological specimens, including museum material. These developments pave the way towards a digital era in morphology. Using sea urchins (Echinodermata: Echinoidea), we provide examples illustrating the power of these techniques. However, remote visualization, the creation of a specialized database, and the implementation of standardized, world-wide accepted data deposition practices prior to publication are essential to cope with the foreseeable exponential increase in digital morphological data.

    Ecological studies on the sand fly Lutzomyia longipalpis (Lutz & Neiva) were conducted during 1990-1993 at a small rural community in Colombia where American visceral leishmaniasis is endemic. Weekly sand fly collections were made from pigpens, houses, and natural resting sites, using hand-held aspirators, sticky (oiled) paper traps, and opossum-baited Disney traps. In total, 263,094 sand flies were collected; L. longipalpis predominated (86.1%), followed by L. trinidadensis (11.0%), L. cayennensis (2.7%), and 8 other Lutzomyia species. The species composition and sex ratio of these sand flies varied among sites and by collection method. L. longipalpis were captured most efficiently by direct aspiration from animal bait. Conversely, sticky paper traps, especially inside houses and at rock resting sites, collected a greater diversity of species, but a lower relative abundance of L. longipalpis.

    Purpose: To evaluate the spatial variations of multiple off-axial targets for a single isocenter stereotactic radiosurgery (SRS) treatment plan in ExacTrac 6D robotic couch system (BrainLab AG). Methods: Five metallic ball bearing (BB) markers were placed sparsely in 3D off-axial locations (non-coplanar) inside a skull phantom as the representatives of multiple targets mimicking multiple brain metastases. The locations of the BB markers were carefully chosen to minimize overlapping of each other in a port imaging detector plane. The skull phantom was immobilized by a frameless mask and CT scanned with a BrainLab Head and Neck Localizer using a GE Optima MDCT scanner. The CT images were exported to iPlan software (BrainLab AG) and a multiple target PTV was drawn by combining all the contours of the BBs. The margin of the MLC opening was selected as 3 mm expansion outward. Two coplanar arc beams were placed to generate a single isocenter SRS plan to treat the PTV. The arc beams were delivered using Novalis Tx system with portal imaging acquisition mode per 10% temporal resolution. The locations of the BBs were visualized and analyzed with respect to the MLC aperture in the treatment plan similar to the Winston-Lutz test. Results: All the BBs were clearly identified inside the MLC openings. The positional errors for the BBs were overall less than 1 mm along the rotational path of the two arcs. Conclusion: This study verified that the spatial deviations of multiple off-axial targets for a single isocenter SRS treatment plan is within sub-millimeter range in ExacTrac 6D robotic couch system. Accompanied with the Winston-Lutz test, this test will quality-assure the spatial accuracies of the isocenter as well as the positions of multiple off-axial targets for the SRS treatment using a single isocenter multiple target treatment plan.

    The nature of the dose-response relationship for various in vivo endpoints of exposure and effect were investigated using the alkylating agents, methyl methanesulfonate (MMS) and methylnitrosourea (MNU). Six male F344 rats/group were dosed orally with 0, 0.5, 1, 5, 25 or 50mg/kg bw/day (mkd) of MMS, or 0, 0.01, 0.1, 1, 5, 10, 25 or 50 mkd of MNU, for 4 consecutive days and sacrificed 24h after the last dose. The dose-responses for multiple biomarkers of exposure and genotoxic effect were investigated. In MMS-treated rats, the hemoglobin adduct level, a systemic exposure biomarker, increased linearly with dose (r (2) = 0.9990, P < 0.05), indicating the systemic availability of MMS; however, the N7MeG DNA adduct, a target exposure biomarker, exhibited a non-linear dose-response in blood and liver tissues. Blood reticulocyte micronuclei (MN), a genotoxic effect biomarker, exhibited a clear no-observed-genotoxic-effect-level (NOGEL) of 5 mkd as a point of departure (PoD) for MMS. Two separate dose-response models, the Lutz and Lutz model and the stepwise approach using PROC REG both supported a bilinear/threshold dose-response for MN induction. Liver gene expression, a mechanistic endpoint, also exhibited a bilinear dose-response. Similarly, in MNU-treated rats, hepatic DNA adducts, gene expression changes and MN all exhibited clear PoDs, with a NOGEL of 1 mkd for MN induction, although dose-response modeling of the MNU-induced MN data showed a better statistical fit for a linear dose-response. In summary, these results provide in vivo data that support the existence of clear non-linear dose-responses for a number of biologically significant events along the pathway for genotoxicity induced by DNA-reactive agents.

    Moore, J; Velarde, E; Wong, J

    2014-06-01

    Purpose: Precision delivery of radiation dose relies on accurate knowledge of the machine isocenter under a variety of machine motions. This is typically determined by performing a Winston-Lutz test consisting of imaging a known object at multiple gantry/collimator/table angles and ensuring that the maximum offset is within specified tolerance. The first step in the Winston-Lutz test is careful placement of a ball bearing at the machine isocenter as determined by repeated imaging and shifting until accurate placement has been determined. Conventionally this is performed by adjusting a stage manually using vernier scales which carry the limitation that each adjustment must be done inside the treatment room with the risks of inaccurate adjustment of the scale and physical bumping of the table. It is proposed to use a motorized system controlled outside of the room to improve the required time and accuracy of these tests. Methods: The three dimensional vernier scales are replaced by three motors with accuracy of 1 micron and a range of 25.4mm connected via USB to a computer in the control room. Software is designed which automatically detects the motors and assigns them to proper axes and allows for small shifts to be entered and performed. Input values match calculated offsets in magnitude and sign to reduce conversion errors. Speed of setup, number of iterations to setup, and accuracy of final placement are assessed. Results: Automatic BB placement required 2.25 iterations and 13 minutes on average while manual placement required 3.76 iterations and 37.5 minutes. The average final XYZ offsets is 0.02cm, 0.01cm, 0.04cm for automatic setup and 0.04cm, 0.02cm, 0.04cm for manual setup. Conclusion: Automatic placement decreased time and repeat iterations for setup while improving placement accuracy. Automatic placement greatly reduces the time required to perform QA.

    The evolutionist ideas of Lamarck, Darwin and Haeckel entered the country through the arrival of their books. "On the origin of Species" arrived in Chile in 1869. The most outstanding immigrant european physicians that discussed these ideas were Rodulfo A Phillippi (1808-1904) and Juan José Brunner (1825-1899). Both discussed Darwin's ideas in their books and conferences as academics of the Faculty of Medicine of the University of Chile. The first Chilean physicians that read and discussed the validity of evolution theory were Adolfo Valderrama (1834-1902) and Pedro Candia Salgado. Both wrote articles about this matter in Revista Médica de Chile in 1872 and 1874. The professor of general biology, Juan Noé Crevani, italian physician and zoologist that arrived in Chile in 1912, was the first to teach directly the concepts of the evolution theory until his death in 1947. Professor Noé founded the great biological school of the twentieth century in Chile and his disciples introduced the concepts of Mendelian theory and neodarwinism in the decade of fifties. The theory of evolution was taught as a chapter of general biology in the Faculty of Medicine between 1913 and 1947, but its practical applications to medicine were introduced with the birth of medical genetics in the decade of fifties and the foundation of Chilean Genetics society in 1964, under the direction of professors Danko Brncic and Gustavo Hoecker, both awarded with the National Sciences Prize.

    This conference report of the Centro de Estudios Migratorios Latinoamericanos and the Center for Migration Studies pertains to meetings held in August 1992. Summary information on migration movements in Latin America is presented by region and subject. The topic of integration in the Americas was presented by Mr. Lelio Marmora. Other topics and presenters include the new Colombian Migration Policy (Mr. Carlos Adolfo Arenas), the integration policies in Central America (Mr. Pilar Norza of Costa Rica, Raimundo Alvarado of El Salvador, and Luis Armando Gusman of Nicaragua), the Andean Pact agreements (representatives of each country), US immigration policy (Charles B. Keely), the Mexican integration with Latin America and immigration to the US (Jorge Bustamante), migration to Bolivia and Argentina and Chile, and transnationalism in the Caribbean (Professor Andre Corten). Migration policy needs to be tailored specifically to the situation in Latin America, and greater attention needs to be devoted to labor migrants' rights and working conditions. There are still fundamental differences among countries in policies regarding the free circulation of persons across borders. There is a division among those who support migration and those who are realists. National sovereignty issues are solvable because of a common national past and a relatively homogenous population. Another opinion is that Latin America is more diverse than commonly recognized. Capital is protected more in international agreements than is migrant labor. Regional integration for the US does mean immigration from Mexico. The US sees Mexican migration as a policy problem, and Mexico sees migration as a labor opportunity.

    The diagnostic categories of the patients discharged from the "Hospital das Clínicas" of the University of São Paulo in 1989 were arranged according the International Classification of Diseases (I.C.D.) and analysed. In each Group sex, age and the reason of discharge or death was indicated. The data concerning 39,601 cases were provided by the Medical Data Service of the "Instituto Central" of the "Hospital das Clínicas". Only the principal diagnosis was taken into account. In the "Instituto de Psiquiatria" most the patients (55.4%) were males between 20 and 49 years of age. The main diagnostic categories were affective psychoses (20.3%), schizophrenic disorders (15%), and disorders related to alcoholism (9.5%). The mortality rate was 0.27%. In the "Instituto da Criança" 56% of the patients that left the hospital were male children and 45.8% of them were less than one year old. Regarding to the diagnostic categories the most important one was that of the diseases of the respiratory system with 27.1% of cases, followed by that of infectious and parasitic diseases with 16.0% of cases. Within the respiratory diseases the most important were the pneumonias caused by not specified microorganisms, and within the infectious diseases the most important was the diarrhea of presumably infectious origin. The mortality rate in this Institute was 9.4%. The "Instituto de Ortopedia e Traumatologia" left 3,825 patients 61.7% males, and 46.9% of them were aged between 20 and 49 years. The greatest number of cases (57.1%) belonged to the Chapter "Injury and Poisoning" followed by that of "Diseases of the Muscoleskeletal System" and Connective Tissue Diseases (23.5%). In this Institute the mortality rate was 1.2%. From the "Instituto do Coração" 7,194 patients were discharged; 65% of them were males, varying their age between 50 and 69 years. The diseases of the circulatory system were mostly ischemic heart disease, miocardiopathies and rheumatic heart diseases. Mortality rate

    2016-09-01

    Following World War II (WWII), there was a new emphasis within genetics on studying the genetic composition of populations. This probably had a dual source in the growing strength of evolutionary biology and the new international interest in understanding the effects of radiation on human populations, following the atomic bombings in Japan. These global concerns were shared by Mexican physicians. Indeed, Mexico was one of the leading centers of this trend in human genetics. Three leading players in this story were Mario Salazar Mallén, Adolfo Karl, and Rubén Lisker. Their trajectories and the international networks in human genetics that were established after WWII, paved the way for the establishment of medical and population genetics in Mexico. Salazar Mallén's studies on the distribution and characterization of ABO blood groups in indigenous populations were the starting point while Karl's studies on the distribution of abnormal hemoglobin in Mexican indigenous populations showed the relationships observed in other laboratories at the time. It was Lisker's studies, however, that were instrumental in the development of population genetics in the context of national public policies for extending health care services to the Mexican population. In particular, he conducted studies on Mexican indigenous groups contributing to the knowledge of the biological diversity of human populations according to international trends that focused on the variability of human populations in terms of genetic frequencies. From the start, however, Lisker was as committed to the reconstruction of shared languages and practices as he was to building networks of collaboration in order to guarantee the necessary groundwork for establishing the study of the genetics of human populations in Mexico. This study also allows us to place Mexican science within a global context in which connected narratives describe the interplay between global trends and national contexts. PMID:27601615

    form of non-linearity at high doses that has been described by Lutz (W.K. Lutz, Dose-response relationship and low dose extrapolation in chemical carcinogenesis, Carcinogenesis, 11 (1990) 1243-1247) as a superlinear dose response. This superlinear response may be due to saturation of metabolic activation enzymes, induction of either DNA repair processes or detoxification enzymes, or other mechanisms. Regardless of the mechanism, this decrease in the DNA-binding potency at moderate to high doses of PAH has important implications for dose-response extrapolation in risk assessment.

    To determine the rabies antibody level of twenty-four hyperimmune equine sera, Standard Mouse Neutralization (SMN) and Couterimmunoelectrophoresis (CIE) tests were carried out, both at the Instituto Butantan (IB) and Instituto Panamericano de Proteccíon de Alimentos y Zoonosis (INPPAZ). Statistical analysis has shown a correlation (r) of 0.9317 between the SMN and CIE performed at the IB, while at the INPPAZ it scored 0.974. Comparison of CIE data of both laboratories yielded a correlation of 0.845. The CIE technique has shown to be a sensitive and efficient as the SMN in titrating antirabies hyperimmune equine sera. Based on CIE results, a simple, rapid and inexpensive technique, titers of sera antibody can be rellably estimated in SMN test.

    Transmission of Leishmania was studied in 27 coffee plantations in the Brazilian State of Minas Gerais. Eighteen females and six males (11.6% of the people tested), aged between 7-65 gave a positive response to the Montenegro skin test. Awareness of sand flies based on the ability of respondents to identify the insects using up to seven predetermined characteristics was significantly greater among inhabitants of houses occupied by at least one Mn+ve individual. Five species of phlebotomine sand fly, including three suspected Leishmania vectors, were collected within plantations under three different cultivation systems. Four of these species i.e., Lu. fischeri (Pinto 1926), Lu. migonei (França 1920), Lu. misionensis (Castro 1959) and Lutzomyia whitmani (Antunes Coutinho 1939) were collected in an organic plantation and the last of these was also present in the other two plantation types. The remaining species, Lu. intermedia (Lutz Neiva 1912), was collected in plantations under both the "adensado" and "convencional" systems. The results of this study indicate that transmission of Leishmania to man in coffee-growing areas of Minas Gerais may involve phlebotomine sand flies that inhabit plantations. PMID:12219123

    The U.S. Geological Survey has recently measured and sampled the Phosphoria formation at many localities in Idaho and other western states. These data will not be fully synthesized and analyzed for several years, but segments of the data, accompanied by little or no interpretation, are published as preliminary reports as they are assembled. This is the fifth report of data containing abstracts of sections measured in southeastern Idaho; it includes about half of the data gathered in Idaho in 1949. The field and laboratory procedures adopted in these investigations are described rather fully in a previous report (McKelvey and others, 1953a). Many people have taken part in this investigation, which was organized and supervised by V. E. McKelvey. F. J. Anderson, A. L. Bush, R. S. Jones, K. B. Krauskopf, K. Lutz, M. E. Thompson, R. G. Waring, and M. A. Warner participated in the description of strata and the collection of samples referred to in this report. T. K. Rigby assisted in the preparation of trenches and the collection, crushing, and splitting of samples in the field. The laboratory preparation of samples for chemical analysis was done in Denver, Colo., under the direction of W. P. Huleatt.

Biophys. Res. Commun. 139, 144-149] and quantified via GLC/MS using characteristic ion traces. 2. The chain-length profile of long-chain 2-hydroxyalkanales clearly indicates their relationship to plasmalogens as precursor molecules. 3.

The constant oxidation rate of plasmalogens in all subcellular fractions provides conclusive evidence for a non-enzymic plasmalogen epoxidation process (probably via hydroperoxy radicals). 5. The high reactivity of alpha-hydroxyaldehydes sheds some doubt on the postulation that plasmalogens protect mammalian cells against oxidative stress as postulated previously [Morand, Zoeller and Raetz (1988) J.

    2014-01-01

    Background Mato Grosso do Sul has been undergoing a process of urbanization which results in loss of native vegetation. This withdrawal makes vectors of man and domestic animals closer, causing changes in the epidemiology of diseases such as American Visceral Leishmaniasis. The aim of the study was to evaluate the phlebotomine fauna and environmental issues related to the transmission of AVL in Ponta Porã, Mato Grosso do Sul, between 2009 and 2010. Methods Vegetation of the urban area was evaluated by Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI) and Soil Adjusted Vegetation Index (SAVI). Results The results showed that the phlebotomine fauna of the city consists of five species, especially Lutzomyia longipalpis (Lutz and Neiva, 1912), the vector of Leishmania (Leishmania) infantum. Predominance of males was observed. The insects were captured in greater quantity in the intradomicile. Lu. longipalpis was the most frequent and abundant species, present throughout the year, with a peak population after the rainy season. Vectors can be found in high amounts in forest and disturbed environments. Conclusions The finding of Lu. longipalpis in regions with little vegetation and humidity suggests that the species is adapted to different sorts of environmental conditions, demonstrating its close association with man and the environment it inhabits. The tourist feature of Ponta Porã reinforces its epidemiological importance as a vulnerable city. The geographical location, bordering Paraguay through dry border, makes possible the existence of a corridor of vectors and infected dogs between the two countries. PMID:24898032

    The prevalence and distribution of soil and water samples contaminated with enteroparasites of humans and animals with zoonotic potential (EHAZP) in Apucaraninha Indigenous Land (AIL), southern Brazil, was evaluated. An environmental survey was conducted to evaluate the presence of parasitic forms in peridomiciliary soil and associated variables. Soil samples were collected from 40/293 domiciles (10 domiciles per season), from November 2010 to June 2011, and evaluated by modified methods of Faust et al. and Lutz. Analyses of water from seven consumption sites were also performed. The overall prevalence of soil samples contaminated by EHAZP was 23.8 %. The most prevalent parasitic forms were cyst of Entamoeba spp. and eggs of Ascaris spp. The highest prevalence of contaminated soil samples was observed in winter (31 %). The probability map obtained with geostatistical analyses showed an average of 47 % soil contamination at a distance of approximately 140 m. The parasitological analysis of water did not detect Giardia spp. or Cryptosporidium spp. and showed that all collection points were within the standards of the Brazilian law. However, the microbiological analysis showed the presence of Escherichia coli in 6/7 sampled points. Despite the low level of contamination by EHAZP in peridomiciliar soil and the absence of pathogenic protozoa in water, the AIL soil and water (due to the presence of fecal coliforms) are potential sources of infection for the population, indicating the need for improvements in sanitation and water treatment, in addition periodic treatment of the population with antiparasitic.

  4. From "forest malaria" to "bromeliad malaria": a case-study of scientific controversy and malaria control.

    PubMed

    Gadelha, P

    1994-08-01

    The article analyses the evolution of knowledge and rationale of control of a special case of malaria transmission based on Bromelia-Kerteszia complex. Since bromeliaceae function as a 'host of the carrier' and were previously associated with natural forests, the elucidation of bromeliad malaria historically elicited controversies concerning the imputation of Kertesziae as transmitters as well as over control strategies directed to bromelia eradication (manual removal, herbicides and deforestation), use of insecticides and chemoprophylaxis. Established authority, disciplinary traditions, conceptual premises and contemporary criteria for validating knowledge in the field partly explain the long time gap since Adolpho Lutz announced at the beginning of the century the existence of a new mosquito and breeding site as responsible for a 'forest malaria' epidemic occurring at a high altitude. The article brings attention to how economic, political and institutional determinants played an important role in redefining studies that led both in Trinidad and Brazil to the recognition of the importance of kerteszia transmission, including urban areas, and establishing new approaches to its study, most relevant of all the concurrence of broad ecological research. The article then describes the Brazilian campaign strategies which showed significant short-term results but had to wait four decades to achieve the goal of eradication due to the peculiar characteristics of this pathogenic complex. Finally, it brings attention to the importance of encompassing social values and discourses, in this case, environmental preservation, to understanding historical trends of malaria control programs.

    Stoichiometric saturation is examined as a possible control on Br contents of halite and sylvite during precipitation from binary salt solutions of NaCl-NaBr and KCl-KBr, respectively. Experimental data at 25°C, assumed to represent Stoichiometric saturation, were used to predict mole fractions of NaBr in halite and KBr in sylvite in thermodynamic equilibrium with fluids as a function of aqueous activity ratios of Br -:Cl -. The predictions are based on the additional assumption that the aqueous activity product of the major salt component in the precipitated salt was independent of the trace Br content in the salt lattice. The extension of the predictions to diagenetic pressures and temperatures is discussed. The predicted equilibrium Br content of halite at initial halite saturation of evaporating seawater is in close agreement with that computed from the distribution coefficient of Lutz (1975), measured in slowgrowth single crystal experiments. Fluid recrystallization of halite and sylvite at near-surface temperatures is predicted to generally deplete the Br contents in the solids. Bulk Br contents in halite in cap-rock of Gulf Coast salt domes generally agree with those predicted by the recrystallization of halite in the presence of evaporative-concentrated seawater. At a constant solution composition, increasing temperature results in increasing the equilibrium Br content of halite, making less efficient Br depletion in halite by recrystallization.

    SUMMARY Strongyloidiasis is a potentially serious infection in immunocompromised patients. Thus, the availability of sensitive and specific diagnostic methods is desirable, especially in the context of immunosuppressed patients in whom the diagnosis and treatment of strongyloidiasis is of utmost importance. In this study, serological and molecular tools were used to diagnose Strongyloides stercoralis infections in immunosuppressed patients. Serum and stool samples were obtained from 52 patients. Stool samples were first analyzed by Lutz, Rugai, and Agar plate culture methods, and then by a quantitative real time polymerase chain reaction (qPCR). Serum samples were evaluated by an enzyme-linked immunosorbent assay (ELISA) using a soluble (AS) or a membrane fractions antigen (AM) obtained from alkaline solutions of the filariform larvae of Strongyloides venezuelensis. Of the 52 immunosuppressed patients, three (5.8%) were positive for S. stercoralis by parasitological methods, compared to two patients (3.8%) and one patient (1.9%) who were detected by ELISA using the AS and the AM antigens, respectively. S. stercoralis DNA was amplified in seven (13.5%) stool samples by qPCR. These results suggest the utility of qPCR as an alternative diagnostic tool for the diagnosis of S. stercoralis infection in immunocompromised patients, considering the possible severity of this helminthiasis in this group of patients.

    We present 1103 trigonometric parallaxes and proper motions from the United States Naval Observatory Robotic Astrometric Telescope (URAT) observations taken at the Naval Observatory Flagstaff Station (NOFS) over a three-year period from 2012 April to 2015 June covering the entire sky north of about -10^\\circ decl. We selected two samples: previously suspected nearby stars from known photometric distances and stars showing a large, significant parallax signature in URAT epoch data without any prior selection criteria. All systems presented in this paper have an observed parallax ≥40 mas with no previous published trigonometric parallax. The formal errors on these weighted parallax solutions are mostly between 4 and 10 mas. This sample gives a significant (of the order of 50%) increase to the number of known systems having a trigonometric parallax to be within 25 pc of the Sun (without applying Lutz-Kelker bias corrections). A few of these are found to be within 10 pc. Many of these new nearby stars display a total proper motion of less than 200 mas yr-1. URAT parallax results have been verified against Hipparcos and Yale data for stars in common. The publication of all signifigant parallax observations from URAT data is in preparation for CDS.

    Culicoides biting midges (Diptera: Ceratopogonidae) are of great medical and veterinary importance because the haematophagous females of some species can transmit diseases to humans and animals. In order to determine the presence and seasonal abundance of the bluetongue virus (BTV) vector Culicoides insignis Lutz at domestic animal sheds in northeastern Brazil, insects were collected once a month between January and December 2010. Light traps were set from 18.00 to 06.00 hours at a pigsty, chicken coop and bovine corral. Culicoides insignis accounted for 81% of the 22,316 specimens collected. Other well-represented species were: Culicoides paucienfuscatus Barbosa (3246 individuals), Culicoides diabolicus Hoffman (308), Culicoides leopoldoi Ortiz (224) and Culicoides duartei Tavares and Luna Dias (221). The remainder accounted for 4% of the total sample. Culicoides insignis occurred mostly at the cattle corral, 98.2% in the rainy season. This study confirms the presence and close association of C. insignis with cattle in Maranhão state, northeastern Brazil and emphasizes the risk of bluetongue infections spreading in the area.

    Cryophilic algae thrive in liquid water within snow and ice in alpine and polar regions worldwide. Blooms of these algae lower albedo (reflection of sunlight), thereby altering melting patterns (Kohshima, Seko & Yoshimura, 1993; Lutz et al., 2014; Thomas & Duval, 1995). Here metagenomic DNA analysis and satellite imaging were used to investigate red snow in Franz Josef Land in the Russian Arctic. Franz Josef Land red snow metagenomes confirmed that the communities are composed of the autotroph Chlamydomonas nivalis that is supporting a complex viral and heterotrophic bacterial community. Comparisons with white snow communities from other sites suggest that white snow and ice are initially colonized by fungal-dominated communities and then succeeded by the more complex C. nivalis-heterotroph red snow. Satellite image analysis showed that red snow covers up to 80% of the surface of snow and ice fields in Franz Josef Land and globally. Together these results show that C. nivalis supports a local food web that is on the rise as temperatures warm, with potential widespread impacts on alpine and polar environments worldwide.

    Ecological studies on the sand fly Lutzomyia longipalpis (Lutz & Neiva) were conducted during 1990-1993 in a small rural community in Colombia where American visceral leishmaniasis is endemic. Standardized weekly sand fly collections made from pigpens and natural resting sites displayed a bimodal annual abundance cycle, with a small peak occurring in October-November and a larger one in April-May. Time series analysis was employed to quantify the associations between sand fly abundance and weather factors (temperature, relative humidity, and rainfall). In addition to a prominent 6-mo cycle. Fourier analysis of the collection data demonstrated that the L. longipalpis population also exhibited a 5- to 8-wk cycle that may represent the length of larval development. Autoregressive moving average models were fit to weekly collection data and their residuals were regressed against rainfall, temperature, and relative humidity. A significant positive association between female L. longipalpis abundance and the relative humidity and rainfall recorded 3 wk earlier was found, indicating that these factors may be of value in predicting sand fly abundance. Additionally, these data indicated that L. longipalpis larvae may become quiescent during adverse conditions.

    Ecological studies on the sand fly Lutzomyia longipalpis (Lutz & Neiva) were conducted during 1990-1992 in a small rural community in Colombia where American visceral leishmaniasis (AVL) is endemic. Subsamples of sand flies collected weekly from pigpens, the interior of houses, and natural outdoor resting sites were dissected to determine physiological age and Leishmania chagasi Cunha & Chagas infection rates. Eleven female L. longipalpis had flagellates in their gut, 2 of which were successfully cultured and identified as Leishmania chagasi. The reproductive status, stage of ovarian development, and trophic history of female sand flies varied among sites, habitats, and time of collection. The percentage of parous females ranged from about one-third to two-thirds overall and varied seasonally. Of most relevance to AVL transmission was the finding that 8% of L. longipalpis females were multiparous. In addition, our data suggest that L. longipalpis rest inside houses after blood-feeding outdoors, and that this species can blood-feed more than once during a single gonotrophic cycle.

    Purpose: A noninvasive fixation mask device is used for stereotactic radiotherapy (SRT) in our hospital. Fractionated SRT is useful because it results in less damage to normal tissues, for which the positioning accuracy of the removable noninvasive fixation device is important. We examined the repositioning accuracy of a BrainLAB removable noninvasive fixation device on the coordinates of computed tomography (CT) for treatment planning. Methods and Materials: The subjects were 13 patients who had undergone head SRT. The removable noninvasive fixation mask device used was a noninvasive fixation device for the BrainLAB system. The accuracy of the irradiation apparatus was evaluated using Winston-Lutz test film, and the repositioning accuracy of the fixation device was examined using differences in the distance on the X, Y, and Z coordinates between the treatment planning and repositioning times determined by comparing the relative coordinates. The evaluation was performed using the relative coordinates of the standard and test points. Results: The accuracy of the irradiation center with the apparatus was within 0.5 mm. In the 13 patients, the difference in the distance between the treatment planning and repositioning procedures ranged from 0.1 to 2.080 mm, and an accuracy of within 2 mm was obtained in 84.6% of the patients using the fixation device. Conclusion: The BrainLAB noninvasive SRT fixation device was considered useful for routine treatment with high accuracy.

    Vitrification is an attractive treatment option for meeting the stabilization and final disposal requirements of many plutonium (Pu) bearing materials and wastes at the Los Alamos National Laboratory (LANL) TA-55 facility, Rocky Flats Environmental Technology Site (RFETS), Hanford, and other Department of Energy (DOE) sites. The Environmental Protection Agency (EPA) has declared that vitrification is the "best demonstrated available technology" for high- level radioactive wastes (HLW) (Federal Register 1990) and has produced a handbook of vitriilcation technologies for treatment of hazardous and radioactive waste (US EPA, 1992). This technology has been demonstrated to convert Pu-containing materials (Kormanos, 1997) into durable (Lutze, 1988) and accountable (Forsberg, 1995) waste. forms with reduced need for safeguarding (McCulhun, 1996). The composition of the Evaporator Bottoms Waste (EVB) at LANL, like that of many other I%-bearing materials, varies widely and is generally unpredictable. The goal of this study is to optimize the composition of glass for EVB waste at LANL, and present the basic techniques and tools for developing optimized glass compositions for other Pu-bearing materials in the complex. This report outlines an approach for glass formulation with fixed property restrictions, using glass property-composition databases. This approach is applicable to waste glass formulation for many variable waste streams and vitrification technologies.. Also reported are the preliminary property data for simulated evaporator bottom glasses, including glass viscosity and glass leach resistance using the Toxicity Characteristic Leaching Procedure (TCLP).

Eating disorder symptomatic (N = 43) and nonsymptomatic (N = 335) women differed on facets of Neuroticism, Extraversion, and Agreeableness. Among symptomatic women, the Oral Control subscale of the EAT-26 was correlated significantly with facets of Neuroticism, Agreeableness and Conscientiousness. Specifically, the Impulsivity facet of Neuroticism was positively correlated with the Bulimia and Food Preoccupation subscale of EAT-26, but negatively correlated with the Oral Control and Dieting subscales. Overall, results suggest that high scores on Neuroticism may be a risk factor for development of disordered eating behavior and that the degree of Impulsiveness may predict the eating disorder subtype to which one is most susceptible.

    The aim of this study was to determine the occurrence of intestinal parasites and commensals among children in four peripheral districts located in the northern, southern, eastern and western sectors of Uberlândia, Minas Gerais, using the Baermann methods as modified by Moraes and Lutz. Out of 160 individuals studied, 93 (58.1% CI: 50.4-65.7) were infected, distributed among the sectors as follows: northern (72.5%), southern (47.5%), eastern (57.5%) and western (55%). The positive findings according to age groups were: 0-5 years (26.9%), 5-10 years (21.2%) and 10-15 years (10%). Male children presented 2.7 times higher risk of infection than females did (OR: 2.7; CI: 1052-7001). The parasites and commensals identified were: Giardia lamblia (27.5%), Entamoeba coli (20.6%), Ascaris lumbricoides (14.4%), Enterobius vermicularis (8.8%), Hymenolepis nana (7.5%), Hymenolepis diminuta (5%), hookworms (3.1%), Trichuris trichiura (2.5%), Endolimax nana (2.5%), Entamoeba hartmanni (2.5%), Strongyloides stercoralis (1.3%), Iodamoeba butschlii (1.3%) and Capillaria hepatica (0.6%). The infection rate in these children was high and showed the need to implement prophylactic education programs in the community. PMID:19142436

The species names are organized in alphabetical order according to the current generic and subgeneric classification, along with their authorship. The list is compiled in order to support mosquito research in Colombia. New information Our systematic review and literature survey found, by 16 February 2015, 13 records of culicid species previously overlooked by mosquito catalogs for Colombia: Anopheles costai da Fonseca & da Silva Ramos, 1939, An. fluminensis Root, 1927, An. malefactor Dyar & Knab, 1907, An. shannoni Davis, 1931, An. vargasi Galbadón, Cova García & Lopez, 1941, Culex mesodenticulatus Galindo & Mendez, 1961, Haemagogus capricornii Lutz, 1904, Isostomyia espini (Martini, 1914), Johnbelkinia leucopus (Dyar & Knab, 1906), Mansonia indubitans Dyar & Shannon, 1925, Psorophora saeva Dyar & Knab, 1906, Sabethes glaucodaemon (Dyar & Shannon, 1925), and Wyeomyia intonca Dyar & Knab, 1909. Moreover, Wyeomyia (Dendromyia) luteoventralis Theobald, 1901 is recorded for Colombia for the first time. This work provides important insights into mosquito diversity in Colombia, using the current nomenclature and phylogenetic rankings. PMID:25829860

Soil samples were collected from 40/293 domiciles (10 domiciles per season), from November 2010 to June 2011, and evaluated by modified methods of Faust et al. and Lutz. Analyses of water from seven consumption sites were also performed. The overall prevalence of soil samples contaminated by EHAZP was 23.8 %. The most prevalent parasitic forms were cyst of Entamoeba spp. and eggs of Ascaris spp. The highest prevalence of contaminated soil samples was observed in winter (31 %). The probability map obtained with geostatistical analyses showed an average of 47 % soil contamination at a distance of approximately 140 m. The parasitological analysis of water did not detect Giardia spp. or Cryptosporidium spp. and showed that all collection points were within the standards of the Brazilian law. However, the microbiological analysis showed the presence of Escherichia coli in 6/7 sampled points. Despite the low level of contamination by EHAZP in peridomiciliar soil and the absence of pathogenic protozoa in water, the AIL soil and water (due to the presence of fecal coliforms) are potential sources of infection for the population, indicating the need for improvements in sanitation and water treatment, in addition periodic treatment of the population with antiparasitic.

    Leishmania infantum, the causative agent of visceral leishmaniasis (VL) in Brazil, is spread mostly by the bite of the sand fly Lutzomyia longipalpis (Lutz & Neiva). We trapped sand flies in endemic neighborhoods near Natal, Brazil, where cases of human and dog VL were documented. Amplification of species-specific cytochrome b (Cyt b) genes by polymerase chain reaction revealed that sand flies from rural and periurban areas harbored blood from different sources. The most common source ofbloodmeal was human, but blood from dog, chicken, and armadillo was also present. We tested the preference for a source of bloodmeal experimentally by feeding L. longipalpis F1 with blood from different animals. There were significant differences between the proportion of flies engorged and number of eggs laid among flies fed on different sources, varying from 8.4 to 19 (P < 0.0001). Blood from guinea pig or horse was best to support sand fly oviposition, but human blood also supported sand fly oviposition well. No sand flies fed on cats, and sand flies feeding on the opossum Monodelphis domestica Wagner produced no eggs. These data support the hypothesis that L. longipalpis is an eclectic feeder, and humans are an important source of blood for this sand fly species in periurban areas of Brazil.

    Chemical insecticides are effective for controlling Lutzomyia and Phlebotomus sand fly (Diptera: Psychodidae) vectors of Leishmania parasites. However, repeated use of certain insecticides has led to tolerance and resistance. The objective of this study was to determine lethal concentrations (LCs) and lethal exposure times (LTs) to assess levels of susceptibility of laboratory Lutzomyia longipalpis (Lutz and Nieva) and Phlebotomus papatasi (Scopoli) to 10 insecticides using a modified version of the World Health Organization (WHO) exposure kit assay and Centers for Disease Control and Prevention (CDC) bottle bioassay. Sand flies were exposed to insecticides coated on the interior of 0.5-gallon and 1,000-ml glass bottles. Following exposure, the flies were allowed to recover for 24 h, after which mortality was recorded. From dose-response survival curves for L. longipalpis and P. papatasi generated with the QCal software, LCs causing 50, 90, and 95% mortality were determined for each insecticide. The LCs and LTs from this study will be useful as baseline reference points for future studies using the CDC bottle bioassays to assess insecticide susceptibility of sand fly populations in the field. There is a need for a larger repository of sand fly insecticide susceptibility data from the CDC bottle bioassays, including a range of LCs and LTs for more sand fly species with more insecticides. Such a repository would be a valuable tool for vector management.

    Phlebotomine sand flies are distributed across nearly all faunal regions of the world, represented by over 800 species, of which many are important vectors of human pathogens. Brazil is currently faced with the expansion and urbanization of leishmaniases, with an increase in the numbers of human cases and seropositive dogs in various medium-sized to large cities. The objective of the current study was to survey the phlebotomine sand fly species in an area endemic for American cutaneous leishmaniasis (ACL) and American visceral leishmaniasis (AVL), i.e., the municipal district of Santa Luzia, lying within the metropolitan region of Belo Horizonte in the Brazilian State of Minas Gerais. Sand flies were collected monthly in 2004-2005 using modified Falcão light traps hung in the peridomiciles of houses and surrounding wooded areas in the district of Baronesa. A total of 1,552 sand flies belonging to seven species was collected, and an interesting pattern of the distribution of the most abundant species relative to the sampling locality was revealed. In the wooded areas Lutzomyia whitmani (Antunes & Coutinho) predominated, whereas in the urban area Lutzomyia longipalpis (Lutz & Neiva) was the most abundant species. These results indicate two possible epidemiological patterns of Leishmania transmission in Santa Luzia: one for American cutaneous leishmaniasis associated predominantly with wooded areas, and another for AVL, with transmission principally occurring around human habitations.

    Cryophilic algae thrive in liquid water within snow and ice in alpine and polar regions worldwide. Blooms of these algae lower albedo (reflection of sunlight), thereby altering melting patterns (Kohshima, Seko & Yoshimura, 1993; Lutz et al., 2014; Thomas & Duval, 1995). Here metagenomic DNA analysis and satellite imaging were used to investigate red snow in Franz Josef Land in the Russian Arctic. Franz Josef Land red snow metagenomes confirmed that the communities are composed of the autotroph Chlamydomonas nivalis that is supporting a complex viral and heterotrophic bacterial community. Comparisons with white snow communities from other sites suggest that white snow and ice are initially colonized by fungal-dominated communities and then succeeded by the more complex C. nivalis-heterotroph red snow. Satellite image analysis showed that red snow covers up to 80% of the surface of snow and ice fields in Franz Josef Land and globally. Together these results show that C. nivalis supports a local food web that is on the rise as temperatures warm, with potential widespread impacts on alpine and polar environments worldwide.

  5. Direct Measures of the Hubble Constant

    When astronomers talk about Lutz-Kelker corrections, metallicity dependent zeropoints, statistical parallaxes, Tully-Fisher relations, "fundamental" planes, light curve decline rates and, worst of all, Malmquist bias, physicists begin heading for the exits, showing signs of severe allergic reaction. They respond less violently to so-called "direct" methods of measuring distances which bypass the traditional distance ladder. Two of these, gravitational lens time delay measurements (Refsdal's method) and the Sunyaev-Zeldovich (S-Z) effect, give distance measurements to objects at high redshift which appear to rival more traditional approaches. Present, model mediated interpretations of such measurements give low values for the Hubble constant. But as is often the case with new techniques, initial enthusiasm is followed by increasing concern about systematic errors connected with messy astrophysical details. The single largest source of error in modelling lenses is the difficulty in constraining the degree of central concentration of the lensing galaxy. Sources of systematic error in S-Z distances include the clumpiness of intracluster gas, temperature variations within that gas and a bias toward selecting clusters that are elongated along the line of sight. Present best estimates of the Hubble constant, along with best estimates of the systematic uncertainties, and the prospects for improving upon these, will be presented.

    Water accumulating in the axils of bromeliads provides habitat for numerous invertebrates, frequently among them, immature mosquitoes. To evaluate mosquito richness in bromeliads and the relationship between mosquito presence and biotic and abiotic variables, we performed a study in the Parque Nacional do Itatiaia, Rio de Janeiro, Brazil. Mosquitoes of genus Culex were the most abundant and varied in species richness, among which nine belonged to subgenus Microculex, Culex (Microculex) neglectus Lutz and Culex ocellatus Theobald being the most frequent species. Sabethines of genera Wyeomyia and Runchomyia were found in low numbers. Wyeomyia (Spilonympha) airosai Lane and Cerqueira and Wyeomyia (Spilonympha) finlayi Lane and Cerqueira tend to proliferate in bromeliads of the genus Bilbergia which hold less than 50 ml of water and grow either alone or with Runchomyia frontosa (Theobald). The larger the volume of water, the greater the chance of finding Culex, Anopheles as well as Wyeomyia (Phoniomyia) species, which seems to be the more generalist as it is present in different bromeliad types with a large range of plant water holding capacities.

    Specimens of Conorhynchos conirostris (Valenciennes, 1840) (Osteichthyes: Siluriformes) were collected from the upper São Francisco River (18 degrees 12'32''S, 45 degrees 15'41''W) in the municipality of Três Marias, Minas Gerais, Brazil, to investigate their parasitofauna. Of the 24 pirá fish collected, 8 were male (33.3%) and 16 were female (66.7%). Of this total, 12 were parasitized (50%). Nine species of parasites were found: Helobdella sp., Creptotrema creptotrema Travassos, Artigas & Pereira, 1928; Palaeocryptogonimus claviformis Szidat, 1954; metacercariae of Clinostomum sp. and of Austrodiplostomum compactum (Lutz 1928); Procamallanus (Spirocamallanus) sp. (young specimen); larvae of Anisakidae and Rhabdochona sp.; and Neoechinorhynchus sp. (young specimen). Helobdella sp. had the highest prevalence, followed by C. creptotrema (most abundant) and P. claviformis. Creptotrema creptotrema was dominant species in the parasite community of C. conirostris. There was no influence of the host size and sex on the prevalence and abundance of parasites, with P. claviformis being found only in male hosts. With the exception of Procamallanus (Spirocamallanus) sp., this was the first record of these parasites in C. conirostris.

    Sand flies are insects of medical and veterinary importance, because some species are able to transmit several pathogens such as Bartonella spp., Phlebovirus spp., and protozoan parasites of the genus Leishmania (Ross). They are widely distributed in the Americas, with recordings ranging from Canada to Argentina. Approximately 500 Phlebotominae species are known in the Americas, of which it is considered that at least 56 are involved in the transmission of leishmaniasis (Maroli et al. 2012). Previous studies have shown that the phlebotomine fauna in Argentina consists of 32 species distributed in 14 provinces (Quintana et al. 2012; Sábio et al. 2015; Salomón et al. 2010). Of these species, Lutzomyia longipalpis (Lutz & Neiva), Nyssomyia neivai (Pinto), Ny. whitmani (Antunes & Countinho), Cortelezzii complex [Evandromyia cortelezzii (Brèthes) - Ev. sallesi (Galvão & Coutinho)], Micropygomyia quinquefer (Dyar) and Migonemyia migonei (França) have been found with DNA of Leishmania spp. (Moya et al. 2015). Five new records of species in the province of Chaco, obtained from different projects carried out between 2001 and 2015, four of which are also new records for Argentina, are described in this article. Their importance as potential vectors and the correct determination of the sympatric species is also discussed.

    In this study, the prevalence and risk factors for enteroparasites were determined in food handlers from Maringá, Paraná State, southern Brazil. Fecal and subungual materials of 150 street food vendors were analyzed by the methods of Lutz, Faust, and Mello, respectively. A questionnaire on hygiene and sanitary conditions of the workplace and of domicile was applied. The prevalence of enteroparasites was 28%, and the protozoa infection was more expressive (21.3%) than by helminths (6.7%), but without significant difference (p > 0.05). Entamoeba coli was the most frequent species occurring in 15.3%, while the prevalence of protozoa pathogenic was low (Giardia lamblia: 2.7% and Entamoeba histolytica: 0.7%). The subungual material presented negative results. The presence of pets in domiciles has increased twice the risk of infection. The working conditions of the majority of street food vendors were inappropriate. The results highlight the need for more rigorous programs of continuing education, parasitological examination every six months, and health surveillance. In this way, the quality of the service provided to the population can be improved and the transmission of food-borne diseases can be prevented.

    Despite overall psychotherapy efficacy (Lambert, 2013), many clients do not benefit (Reese, Duncan, Bohanske, Owen, & Minami, 2014), dropouts are a problem (Swift & Greenberg, 2012), and therapists vary significantly in success rates (Baldwin & Imel, 2013), are poor judges of negative outcomes (Chapman et al., 2012), and grossly overestimate their effectiveness (Walfish, McAlister, O'Donnell, & Lambert, 2012). Systematic client feedback offers 1 solution (Duncan, 2014). Several feedback systems have emerged (Castonguay, Barkham, Lutz, & McAleavey, 2013), but only 2 have randomized clinical trial support and are included in the Substance Abuse and Mental Health Administration's National Registry of Evidence-Based Programs and Practices: The Outcome Questionnaire-45.2 System (Lambert, 2010) and the Partners for Change Outcome Management System (PCOMS; Duncan, 2012). This article presents the current status of PCOMS, the psychometrics of the PCOMS measures, its empirical support, and its clinical and training applications. Future directions and implications of PCOMS research, training, and practice are detailed. Finally, we propose that systematic feedback offers a way, via large-scale data collection, to reprioritize what matters to psychotherapy outcome, reclaim our empirically validated core values and identity, and change the conversation from a medical model dominated discourse to a more scientific, relational perspective.

    This study reports on the occurrence of enteroparasites based on data from an ethnographic study of food handlers in the city of Cascavel, Paraná, Brazil. Fecal material from 343 food handlers of both sexes, between 14 and 75 years of age, was analyzed using Lutz, modified Ritchie and Ziehl-Neelsen techniques. Ethnographic relationships were investigated by means of specific questionnaires. Positive fecal samples were found for 131 (38.2%) handlers. Endolimax nana (67.9%) was the predominant species, followed by Entamoeba coli (35.9%), Blastocystis hominis (28.2%), Entamoeba histolytica/dispar (10.1%) and Giardia duodenalis (8.4%). Protozoan infections were more common than helminth infections (p = 0.00). The positive results for some parasites were associated with the male sex, professional category, and the performance of other activities (p < 0.05). The high overall occurrence of enteroparasites found indicates improper hygiene and sanitation conditions. Effective educational measures should be implemented to prevent the transfer of pathogenic organisms to food via handling.

    The incredible mosquito species diversity in the Neotropics can provoke major confusion during vector control programs when precise identification is needed. This is especially true in French Guiana where studies on mosquito diversity practically ceased 35 yr ago. In order to fill this gap, we propose here an updated and comprehensive checklist of the mosquitoes of French Guiana, reflecting the latest changes in classification and geographical distribution and the recognition of current or erroneous synonymies. This work was undertaken in order to help ongoing and future research on mosquitoes in a broad range of disciplines such as ecology, biogeography, and medical entomology. Thirty-two valid species cited in older lists have been removed, and 24 species have been added including 12 species (comprising two new genera and three new subgenera) reported from French Guiana for the first time. New records are from collections conducted on various phytotelmata in French Guiana and include the following species: Onirion sp. cf Harbach and Peyton (2000), Sabethes (Peytonulus) hadrognathus Harbach, Sabethes (Peytonulus) paradoxus Harbach, Sabethes (Peytonulus) soperi Lane and Cerqueira, Sabethes (Sabethinus) idiogenes Harbach, Sabethes (Sabethes) quasicyaneus Peryassú, Runchomyia (Ctenogoeldia) magna (Theobald), Wyeomyia (Caenomyiella) sp. cf Harbach and Peyton (1990), Wyeomyia (Dendromyia) ypsipola Dyar, Wyeomyia (Hystatomyia) lamellata (Bonne-Wepster and Bonne), Wyeomyia (Miamyia) oblita (Lutz), and Toxorhynchites (Lynchiella) guadeloupensis (Dyar and Knab). At this time, the mosquitoes of French Guiana are represented by 235 species distributed across 22 genera, nine tribes, and two subfamilies.

    Owing to the existence of cryptic species that are difficult to distinguish morphologically, the search for new taxonomic characters and methods for identifying and classifying sand flies continues. Lutzomyia longipalpis (Lutz & Neiva, 1912) and Lutzomyia cruzi (Mangabeira, 1938) (Diptera: Psychodidae) are two such species that occur in sympatry in some regions of Mato Grosso do Sul State (MS). Twenty females and twenty males from each of the five populations of Lu. longipalpis and one population of Lu. cruzi from MS were examined. An outlying population of Lu. longipalpis from Estrela de Alagoas, State of Alagoas, was used to compare the degree of divergence among the groups in MS. Specimens were cleared, mounted on slides, identified, and measured using LAS-Leica. The principal component analysis of morphometric characters showed a high degree of variation among females, while males varied to a lower degree. The populations of Alagoas and Miranda demonstrated the greatest variation. The first region, Alagoas, is geographically distant from the others and occurs under distinctly different ecological conditions, which likely accounts for the variation. Further studies should be made to elucidate the factors that contribute to the differences found between the populations of MS.

    Blastocystis homins is a protozoan that causes an intestinal infection known as human blastocystosis. This infection is diagnosed by means of parasitological examination of stools and by permanent staining techniques. The present study was developed to evaluate the frequency of Blastocystis hominis infection among inhabitants of the Araraquara region, State of São Paulo, and to compare different methods for investigating this protozoan in feces samples. Evaluations on 503 stool samples were performed by means of direct fresh examination and using the techniques of Faust et al., Lutz and Rugai et al. In addition, the iron hematoxylin, trichrome and modified Kinyoun staining techniques were used. Out of the 503 samples examined, 174 (34.6%) were found to be positive for the presence of intestinal parasites. The most frequent protozoa and helminths were Entamoeba coli (14.6%) and Strongyloides stercoralis (6.7%), respectively. Blastocystis hominis was present in 23 (4.6%) fecal samples, with a predominately pasty consistency and without characterizing a condition of diarrhea. Despite the low frequency of Blastocystis hominis found in the Araraquara region, compared with other regions of Brazil, it is important to perform laboratory diagnostic tests for this protozoan. Its finding in fecal material is indicative of food and drinking water contamination. Since the transmission route for this parasite is accepted to be oral-fecal, this implies that the population needs guidance regarding hygiene and basic sanitation measures as a means for controlling health problems caused by enteroparasites.

    An intensive search for the larval habitats of Lutzomyia longipalpis (Lutz & Neiva) was conducted from November 1992 to October 1993 at a small rural community in Colombia where American visceral leishmaniasis is endemic. Emergence traps constructed from polyvinyl chloride pipes were used to sample a variety of soil microhabitats that included edge areas of covered pigpens, cattle corrals, the base of trees, and leaf litter at sites within 40 m of a house, rocks in fields located between 50 and 500 m from houses, and sites within a patch of secondary forest (rocks, base of palm trees, and leaf litter). The teneral status of the sand flies captured in the emergence traps was confirmed by laboratory studies that determined the rate of terminalia rotation in male L. longipalpis and the rate of cuticular growth layer formation of the thoracic phragma in both sexes of this species. A total of 58 teneral sand flies was captured during the study period (49 wk). Fifteen specimens were L. longipalpis; of these 11 (5 sand flies per square meter) were captured near pigpens, 3 (1.4 sand flies per square meter) were captured near rock resting sites, and 1 (1.6 sand flies per square meter) was collected at the base of a tree. The remainder of the sand flies were either L. trinidadensis (Newstead) or L. cayennensis (Flock & Abonnenc). Our results indicate that L. longipalpis larvae were dispersed widely in sites near houses, rather than concentrated in a few optimal microhabitats.

    Fruit flies were used by several laboratories between 1901 and 1910 for studies of experimental evolution at Harvard, Indiana University, and Cold Spring Harbor before Thomas Hunt Morgan found his white-eyed mutation that we associate with the beginnings of the fly lab at Columbia University. The major players prior to Morgan were William Castle and his students at Harvard University, Frank Lutz at Cold Spring Harbor, and Fernandus Payne whose ideas for working with fruit flies were shaped by his studies of blind cave fauna at Indiana University. Payne's interests were stimulated by the work of Carl Eigenmann, an authority on blind cave fauna, and William Moenkhaus, who introduced Payne to fruit flies at Indiana University before Payne moved to Columbia to pursue graduate work with Morgan and Edmund Wilson. The motivations of the laboratories differed in the theories used for their work. Castle spread the word about the utility of fruit flies for research, but Payne gave Morgan his first fruit flies for research leading to the discovery of the white-eye mutation.

    We present a theoretical method for the design and optimization of quantum corrals[1] with specific electronic properties. Taking advantage that spins are subject to a RKKY interaction that is directly controlled by the scattering of the quantum corral, we design corral structures that reproduce spin Hamiltonians with coupling constants determined a priori[2]. We solve exactly the bi-dimensional scattering problem for each corral configuration within the s-wave approximation[3] and subsequently the geometry of the quantum corral is optimized by means of simulated annealing[4] and genetic algorithms[5]. We demonstrate the possibility of automatic design of structures with complicated target electronic properties[6].

    Secondary electron production as a consequence of inner-shell vacancy decay for the Kr-Kr system has been studied. Electron-energy spectra differential in impact parameter have been obtained by detecting electrons in coincidence with projectile ions scattered through a known angle. The spectra exhibit structure attributable to Auger decay of L-shell vacancies. The collision-energy dependence of the L-Auger yields is consistent with the L-shell excitation being due to rotational coupling of the 4fsigma , 4fpi, 4fdelta and 4fvarphi orbitals of the Kr-Kr quasimolecule, as originally proposed by Shanker and coworkers.^1 The L-Auger electron energies and relative transition-group intensities suggest that L-shell vacancy decay occurs in Kr ions with initial charge states greater than +10, indicating that a surprisingly large number of electrons are emitted prior to the decay of the L-shell vacancy. These prior ionizations, most of which occur during the collision, are the source of the 100-600 eV continuum electrons which dominate the low -energy region of the electron spectrum. ftn^1 R.

    Recently a special parallel-plate ionization chamber was developed and characterized at the Instituto de Pesquisas Energeticas e Nucleares. The operational tests presented results within the recommended limits. In order to determine the influence of some components of the ionization chamber on its response, Monte Carlo simulations were carried out. The experimental and simulation results pointed out that the dosimeter evaluated in the present work has favorable properties to be applied to 60Co dosimetry at calibration laboratories.

    An application of high energy physics instrumentation is to look for structure or different densities (materials) hidden in a matrix (tons) of material. By tracing muons produced by primary Cosmic Rays, it has been possible to generate a kind of radiographs which shows the inner structure of dense containers, monuments or mountains. In this paper I review the basics principles of such techniques with emphasis in the Sun Pyramid project, carried out by IFUNAM in collaboration with Instituto Nacioanal de Antropologia e Historia.

    The Carlsberg Meridian Catalogues give accurate positions, proper motions and magnitudes of stars north of declination -45deg and down to 15th magnitude. They also contain observations of the solar system objects: Mars, Callisto, Saturn, Titan, Iapetus, Uranus, Neptune, Pluto, and many minor planets. Typical mean errors for an entry are 0.1arcsec in position, 3mas/yr in proper motion, and 0.05mag in magnitude. The stars observed belong to a large number of observing programmes typically dealing with the reference frame or with galactic kinematics. The Carlsberg Automatic Meridian Circle on La Palma is operated by Copenhagen University Observatory, Royal Greenwich Observatory, and Real Instituto y Observatorio de la Armada at the Observatory del Roque de los Muchachos of the Instituto de Astrofisica de Canarias. For a detailed introduction, please refer to the printed catalogue. A description of the programme may also be found in the 1993 paper by Fabricius (=1993BICDS..42....5F), from which the present description is derived. Originally the CMC7 was planned to contain only observations from 1991. The actual CMC7 comprises nearly 20 month (January 1991 to August 1992) and is thus more extensive than foreseen when a description was published in Bull.

Over a period of more than 10 years, a large collection of photographic pictures of the southern sky were obtained with the ESO 1-m Schmidt Telescope, a wide-angle telescope at the La Silla observatory in Chile that has now been decommissioned. Thanks to a large glass prism in the front of the telescope, every object in the observed sky field - stars as well as galaxies - was imaged as a small spectrum, providing a first rough idea about its type and composition. The main aim of this "Hamburg/ESO survey" (with Dieter Reimers , Associate Director of the Hamburger Sternwarte, as Principal Investigator and Lutz Wisotzki , now at Astrophysikalisches Institut Potsdam, Germany, as Project Scientist) was to find quasars (particularly active centres of galaxies), a task that was accomplished most successfully, cf. e.g., ESO PR 10/97 and ESO PR 08/00 (Report F). A very welcome by-product of this survey has been a rich harvest of very metal-poor stars . This part of the project is led by Norbert Christlieb , also from the Hamburg Observatory, and now on sabbatical leave at the Research School of Astronomy and Astrophysics of the Australian National University (Canberra, Australia). Using fast computers and advanced pattern-recognition software to analyze the photographic exposures and thus to sift through millions of registered stellar spectra, about 8000 candidates for very metal-poor stars were found. These stars are now being scrutinized spectroscopically one-by-one with many medium-sized telescopes all over the world. Confirmed candidates are then observed with the largest telescopes in the world in order to obtain very detailed spectra (of high spectral resolution), which allow the astronomers to determine their chemical composition accurately.

    Cadalso de los Vidrios leucogranite is extracted from the Sierra de Guadarrama (Spanish Central System), about 75 kilometers southwest of Madrid. "Cadalso" means "high place", the topography of Cadalso de los Vidrios village is dominated by the Peña Muñana, where there is an eighth century Arab watchtower built with leucogranite. "Vidrios" refers to glass factories that existed in Cadaso de los Vidrios from the late twelfth century. Today there are no glass factories and quarrying is an important industry, Cadalso de los Vidrios has three quarry zones, and many processing and carving workshops. Cadalso de los Vidrios leucogranite is a fine-medium-grained, hypidiomorphic, equigranular leucogranite. There are many historical buildings built with thisstone, including the archeological site of "La Mezquita" whose original mosque was built between the years 950 and 1012 and the Villena Palace which dates from the fifteenth century. In 1534, this was rebuilt into a Renaissance-style castle In addition the "Arco de la Ermita de Santa Ana" was built between 1463 and 1492 and the Nuestra Señora de la Asunción Church was built in 1498 with its façade being completed in Plateresque-style in 1547.as the "Casa de los Salvajes". The Cadalso de los Vidrios City Hall was built in 1992 also with leucogranite. The current annual production of the Cadalso de los Vidrios leucogranite is 8000 m3, of which 40% is exported primarily to France and Italy. Currently, under the trade name Blanco Cristal, it has been used in places such as Vieux-Port in Marseille, in France; Plaza Romagné Conflans in Ste Honorine (France); Cork International Airport, in Ireland; Terminal 4 of Adolfo Suarez Airport, in Madrid; shopping malls in Dortmund, Germany as well as in Guangzhou, China and the Puri EXIM Bank, in Jakarta.

    We report results obtained from a stratigraphic and paleomagnetic study of Plio-Pleistocene sedimentary rocks in the Borrego Badlands, E of Borrego Springs, CA. The Borrego Badlands are bordered by dextral strike slip faults of the San Jacinto fault zone (Clark fault to the NE, Coyote Creek fault to the SW), and is also cut by several NE-striking sinistral faults (linked antithetically to the Coyote Creek and Clark faults), the largest of which is the Inspiration Point fault. Our work focuses on deposits of the Palm Spring Group, including Pliocene fluvial/deltaic sandstones of the Arroyo Diablo Formation and Plio-Pleistocene lacustrine mudstones of the Borrego Formation. We collected a suite of 54 paleomagnetic sample sites from a 2500 m thick section of the Borrego Badlands (3rd Wash, Hills of the Moon Wash, and Rainbow Wash), from the upper part of the Arroyo Diablo Formation to the contact between the Borrego Formation and overlying Ocotillo Formation. This section is correlated to the upper Borrego and Ocotillo formations in Beckman Wash, located NW of here on the NW side of the Inspiration Point fault, allowing us to use the previous magnetostratigraphy of Lutz et al (2006) as a tie point for this section. Sample sites were spaced at 15 to 100 m, and 5 to 8 samples were collected from each site. Samples were thermally demagnetized using steps from 80 to 690 C, and two magnetization components were observed from 53 of the sites. A total of 49 sites had well-defined second-removed components and site mean directions that were robust (k>10). The combined mean of these 49 sites is D = 35, I = 41, α95 = 7.5. We identify 8 polarity zones in this section, ranging from near the base of the Gauss magnetochron to the upper part of the Matuyama chron, including the Mammoth, Kaena, and Olduvai subchrons. The contact between the Arroyo Diablo and Borrego formations is estimated to be ~2.9 Ma. Sediment-accumulation rates are relatively rapid and vary between 0.7 and 1

    As a species subject to photolytic, chemical and condensation losses, H2O present in Titan's stratosphere must be of external origin. The discovery of CO2 by Voyager (Samuelson et al. 1981) pointed to an external supply of oxygen to Titan's atmosphere. Indeed, CO2, which also condenses, was recognized to be formed via CO+OH, where OH was likely produced by H2O photolysis. This view was supported by the ground-based discovery of CO (Lutz et al. 1983) and subsequent measurements confirming an abundance of ~50 ppm. The source of CO itself remained elusive, but inspired by the Cassini/CAPS discovery of a O+ influx rate (Hartle et al. 2006), Hörst et al. (2008) showed that an external source of O or O+ leads to the formation of CO, also pointing to the likely external origin of this compound. The most up-to-date model of Titan's oxygen chemistry by Hörst et al. (2008) adjusted the OH/H2O deposition rate as a function of the eddy diffusion coefficient below 200 km to match the observed CO2 mixing ratio (15 ppb, uniform over 100-200 km), and producing a H2O profile that was deemed consistent with ISO/SWS measurement of the H2O abundance at a nominal altitude of 400 km (Coustenis et al. 1998). Therefore, the Hörst et al. (2008) study provided an apparently self-consistent picture of the origin of oxygen compounds in Titan's atmosphere, with the three main species (CO, CO2 and H2O) being produced from a permanent external supply of oxygen in two distinct forms. However, recent measurements of several H2O lines by the HIFI and PACS instruments (Herschel Space Observatory) have shown that none of the H2O profiles calculated in Hörst et al. (2008) reproduces the observed lines (Moreno et al., this workshop), and neither does the Lara et al. (1996) H2O profile. Here we revisit the Lara et al. (1996) photochemical model by including (i) an updated eddy diffusion coefficient profile (K(z)), constrained by the C2H6 vertical distribution (ii) an adjustable O+/OH/H2O influx. Our

    CEO Peter Walsh faces a classic innovator's dilemma. His company, Crescordia, produces high-quality metal plates, pins, and screws that orthopedic surgeons use to repair broken bones. In fact, because the company has for decades refused to compromise on quality, there are orthopedic surgeons who use nothing but Crescordia hardware. And now these customers have begun to clamor for the next generation technology: resorbable hardware. Resorbables offer clear advantages over the traditional hardware. Like dissolving sutures, resorbable plates and screws are made of biodegradable polymers. They hold up long enough to support a healing bone, then gradually and harmlessly disintegrate in the patient's body. Surgeons are especially looking forward to using resorbables on children, so kids won't have to undergo a second operation to remove the old hardware after their bones heal, a common procedure in pediatrics. The new products, however, are not yet reliable; they fail about 8% of the time, sometimes disintegrating before the bone completely heals and sometimes not ever fully disintegrating. That's why Crescordia, mindful of its hard-earned reputation, has delayed launching a line using the new technology. But time is running out. A few competitors have begun to sell resorbables despite their imperfections, and these companies are picking up market share. Should Crescordia join the fray and risk tarnishing its brand? Or should the company sit tight until it can offer a perfect product? Commenting on this fictional case study are Robert A. Lutz, vice chairman of product development at General Motors; Clayton M. Christensen, the Robert and Jane Cizik Professor of Business Administration at Harvard Business School; Jason Wittes, a senior equity analyst covering medical supplies and devices at Leerink Swann; and Nick Galakatos, a general partner of MPM Capital.

    We report on the high-precision timing of 42 radio millisecond pulsars (MSPs) observed by the European Pulsar Timing Array (EPTA). This EPTA Data Release 1.0 extends up to mid-2014 and baselines range from 7-18 yr. It forms the basis for the stochastic gravitational-wave background, anisotropic background, and continuous-wave limits recently presented by the EPTA elsewhere. The Bayesian timing analysis performed with TEMPONEST yields the detection of several new parameters: seven parallaxes, nine proper motions and, in the case of six binary pulsars, an apparent change of the semimajor axis. We find the NE2001 Galactic electron density model to be a better match to our parallax distances (after correction from the Lutz-Kelker bias) than the M2 and M3 models by Schnitzeler. However, we measure an average uncertainty of 80 per cent (fractional) for NE2001, three times larger than what is typically assumed in the literature. We revisit the transverse velocity distribution for a set of 19 isolated and 57 binary MSPs and find no statistical difference between these two populations. We detect Shapiro delay in the timing residuals of PSRs J1600-3053 and J1918-0642, implying pulsar and companion masses m_p=1.22_{-0.35}^{+0.5} M_{⊙}, m_c = 0.21_{-0.04}^{+0.06} M_{⊙} and m_p=1.25_{-0.4}^{+0.6} M_{⊙}, m_c = 0.23_{-0.05}^{+0.07} M_{⊙}, respectively. Finally, we use the measurement of the orbital period derivative to set a stringent constraint on the distance to PSRs J1012+5307 and J1909-3744, and set limits on the longitude of ascending node through the search of the annual-orbital parallax for PSRs J1600-3053 and J1909-3744.

  14. The orthology of HLA-E and H2-Qa1 is hidden by their concerted evolution with other MHC class I molecules

    Joly, Etienne; Rouillon, Virginie

    2006-01-01

    Background Whether MHC molecules undergo concerted evolution or not has been the subject of a long-standing debate. Results By comparing sequences of eight functional homologues of HLA-E from primates and rodents with those of MHC class Ia molecules from the same eight species, we find that different portions of MHC class I molecules undergo different patterns of evolution. By focusing our analyses sequentially on these various portions, we have obtained clear evidence for concerted evolution of MHC class I molecules, suggesting the occurrence of extensive interallelic and intergenic exchanges. Intra-species homogenisation of sequences is particularly noticeable at the level of exon 4, which codes for the α3 domain, but our results suggest that homogenisation also concerns certain residues of the α1–α2 codomain that lie outside the antigen recognition site. Conclusion A model is presented in which Darwinian selective pressures due to pathogens could, at the same time, favour diversification of MHC class Ia molecules and promote concerted evolution of separate loci by spreading advantageous motifs arising by mutations in individual MHC molecules to other alleles and to other loci of the MHC region. This would also allow MHC molecules to co-evolve with the proteins with which they interact to fulfil their functions of antigen presentation and regulation of NK cell activity. One of the raisons d'être of the MHC may therefore be to favour at the same time both diversification of MHC class Ia molecules and homogenisation of the whole pool of MHC class I molecules (Ia and Ib) involved in antigen presentation.

    The study of some of the behavioral aspects of the main vector of Leishmania infantum chagasi Cunha & Chagas in the Americas, Lutzomyia longipalpis (Lutz & Neiva), such as dispersion, population size, and vector survival rates, is important for the elucidation of the mechanisms of visceral leishmaniasis transmission. These parameters were studied by means of capture-mark-release-recapture experiments in an urban area of Campo Grande municipality, an endemic area of visceral leishmaniasis, situated in Mato Grosso do Sul state, Brazil. Six capture-mark-release-recapture experiments were undertaken between November 2009 and November 2010 and once in January 2012 with a view to assessing the population size and survival rate of Lu. longipalpis. The insects were released in a peridomicile surrounded by 13 residences. The recaptures were undertaken with automatic light traps for four consecutive weeks after release in the surrounding area. In total, 3,354 sand flies were captured, marked, and released. The overall recapture rate during the capture-mark-release-recapture experiments was 4.23%, of which 92.45% were recaptured at the release site, indicating limited dispersal. The greatest distance recorded from the release site was 165 m for males and 241 m for females. The male daily survival rate, calculated on the basis of regressions from the numbers of marked recaptured insects during the 15 successive days after release was 0.897. The estimated male population size measured by the Lincoln Index was 10,947.127. Though Lu. longipalpis presented a limited dispersion the physical barriers typical of urban environments did not prevent the sand flies from flying long distances.

    Intestinal parasitic infections are currently a source of concern for Public Health agencies in developing and developed countries. Since three ovum-and-parasite stool examinations have been demonstrated to provide sensitive results, we designed a practical and economical kit (TF-Test) that is now commercially available (Immunoassay Com. Ind. Ltda., São Paulo, Brazil). This kit allows the separate collection of three fecal specimens into a preservative solution. The specimens are then pooled, double-filtered, and concentrated by a single rapid centrifugation process. The TF-Test was evaluated in four different laboratories in a study using 1,102 outpatients and individuals living in an endemic area for enteroparasitosis. The overall sensitivity found using the TF-Test (86.2-97.8%) was significantly higher (P<0.01) than the sensitivity of conventional techniques such as the Coprotest (NL Comércio Exterior Ltda, São Paulo, Brazil) and the combination of Lutz/Hoffman, Faust, and Rugai techniques (De Carli, Diagnóstico Laboratorial das Parasitoses Humanas. Métodos e Técnicas, 1994), which ranged from 48.3% to 75.9%. When the above combined three specimen technique was repeated with three specimens collected on different days, its sensitivity became similar (P>0.01) to that of the TF-Test. The kappa index values of agreement for the TF-Test were consistent (P<0.01), being higher and ranking in a better position than conventional techniques. The high sensitivity, cost/benefit ratio, and practical aspects demonstrate that the TF-Test is suitable for individual diagnosis, epidemiological inquiries, or evaluation of chemotherapy in treated communities.

  17. From magic to science: a journey throughout Latin American medical mycology.

    The start of Latin America's love story with fungi may be placed in pre-Hispanic times when the use of fungi in both ritual ceremonies and daily life were common to the native civilizations. But the medical mycology discipline in Latin America started at the end of the 19th Century. At that time, scholars such as A. Posadas, R. Seeber, A. Lutz and P. Almeida, discovered agents of fungal diseases, the study of which has influenced the regional research ever since. Heirs to them are the researchers that today thrive in regional Universities and Research Institutes. Two current initiatives improve cooperation among Latin American medical mycologists. First, the periodical organization of International Paracoccidioidomycosis Meetings (seven so far, from 1979 to 1999); second, the creation of the Latin American Association for Mycology in 1991 (three Congresses, from 1993 to 1999). Latin American publications have increased in international specialized journals such as that from our Society (ISHAM) (from 8% in 1967 to 19% in 1999), and the Iberoamerican Journal of Mycology (Revista Iberoamericana de Micologia; > 40% from 1997 to 1999). In addition, Latin American participation at ISHAM International Congresses has risen from 6.9% in 1975 to 21.3% in 1997, and 43.2% at the 14th ISHAM Congress, held for the first time in a Latin American country, Argentina. A significant contribution of women to the scientific establishment of Latin American medical mycology (e.g., 45% of Latin American papers vs. 18% of other regions published in Journal of Medical and Veterinary Mycology in 1987, had women as authors or coauthors) suggests a better academic consideration of Latin American women against their counterparts in the developed world. Taken together, all these figures reflect the enthusiasm of our Latin American colleagues in the field, despite the difficulties that afflict our region, and affect our work.

    The Center for Tropical Forest Research (CTFS), a program of the Smithsonian Tropical Research Institute (STRI), has coordinated a global network of 17 tropical forest dynamics plots of approximately 50 hectares in order to collect baseline information and to monitor forest changes. Missing from most past studies of these plots is an integrated soil hydrology and water chemistry component. To fill this gap, we have developed and are testing rapid assessment methods to measure soil and hydrological properties for tropical forest catchments. This assessment includes gaging and sampling first to third order headwater streams with high frequency over several storm events within a 2-4 week period. Detailed flow separations enable us to test Elsenbeer's (2001) functional classification continuum for tropical soils and allow us to test the hypothesis that forest sites with greater overland flow experience greater nutrient loss during storm events. Data from a storm event for the steep Lutz Creek Catchment on Barro Colorado Island, Panama in September 1990 demonstrate that Na+ and Si, typical of most solutes, decrease in concentration with increasing discharge. In contrast, the nutrients, K+ and NO3- increase in concentration with increasing discharge. Results from a 20 ha catchment in Yasuni National Park, Ecuador from November 2003 show a similar pattern during several small events on relatively impermeable soils. Data collected from a more permeable 20 ha catchment in Lambir Hills National Park, Malaysia in July 2004 also show nutrient export, but suggest that rainfall amount, intensity and duration may play a large role in the magnitude of nutrient concentrations.

    The information processing capacity of the human mind is limited, as is evidenced by the attentional blink-a deficit in identifying the second of two targets (T1 and T2) presented in close succession. This deficit is thought to result from an overinvestment of limited resources in T1 processing. We previously reported that intensive mental training in a style of meditation aimed at reducing elaborate object processing, reduced brain resource allocation to T1, and improved T2 accuracy [Slagter, H. A., Lutz, A., Greischar, L. L., Francis, A. D., Nieuwenhuis, S., Davis, J., et al. Mental training affects distribution of limited brain resources. PloS Biology, 5, e138, 2007]. Here we report EEG spectral analyses to examine the possibility that this reduction in elaborate T1 processing rendered the system more available to process new target information, as indexed by T2-locked phase variability. Intensive mental training was associated with decreased cross-trial variability in the phase of oscillatory theta activity after successfully detected T2s, in particular, for those individuals who showed the greatest reduction in brain resource allocation to T1. These data implicate theta phase locking in conscious target perception, and suggest that after mental training the cognitive system is more rapidly available to process new target information. Mental training was not associated with changes in the amplitude of T2-induced responses or oscillatory activity before task onset. In combination, these findings illustrate the usefulness of systematic mental training in the study of the human mind by revealing the neural mechanisms that enable the brain to successfully represent target information.

    Band 3 modifications that normally occur during physiological red blood cell (RBC) senescence in humans, and occasionally in pathological conditions are described in the context of their role in enhancing RBC recognition and phagocytic removal. Band 3 modifications are mostly due to oxidative insults that gradually accumulate during the RBC lifespan or impact massively in a shorter time period in pathological conditions. The oxidative insults that impact on the RBC, the protective mechanisms that counteract those damages and the phenotypic modifications that accumulate during the RBC lifespan are described. It is shown how specific oxidative as well as non-oxidative band 3 modifications enhance RBC membrane affinity for normally circulating anti-band 3 antibodies, and how membrane-bound anti-band 3 antibodies bring about a limited complement activation and membrane deposition of complement C3 fragments. The partially covalent complexes between anti-band 3 antibodies and complement C3 fragments are very powerful opsonins readily recognized by the CR1 complement receptor on the phagocyte. Band 3 modifications typically encountered in old RBCs have crystallized to a number of band 3-centered models of RBC senescence. One of those band 3-centered models, the so-called 'band 3/complement RBC removal model' first put up by Lutz et al. is discussed in more detail. Finally, it is shown how the genetic deficiency of glucose-6-phosphate dehydrogenase (G6PD) plus fava bean consumption, and a widespread RBC parasitic disease, P. falciparum malaria, may lead to massive and rapid destruction of RBCs by a mechanism comparable to a dramatic, time-compressed enhancement of normal RBC senescence.

    Purpose: Gantry sag is one of the well-known sources of mechanical imperfections that compromise the spatial accuracy of radiation dose delivery. The objectives of this study were to quantify the gantry sag on multiple linear accelerators (linacs), to investigate a multileaf collimator (MLC)-based strategy to compensate for gantry sag, and to verify the gantry sag and its compensation with film measurements. Methods: The authors used the Winston–Lutz method to measure gantry sag on three Varian linacs. A ball bearing phantom was imaged with megavolt radiation fields at 10° gantry angle intervals. The images recorded with an electronic portal imaging device were analyzed to derive the radiation isocenter and the gantry sag, that is, the superior–inferior wobble of the radiation field center, as a function of the gantry angle. The authors then attempted to compensate for the gantry sag by applying a gantry angle-specific correction to the MLC leaf positions. The gantry sag and its compensation were independently verified using film measurements. Results: Gantry sag was reproducible over a six-month measurement period. The maximum gantry sag was found to vary from 0.7 to 1.0 mm, depending on the linac and the collimator angle. The radiation field center moved inferiorly (i.e., away from the gantry) when the gantry was rotated from 0° to 180°. After the MLC leaf position compensation was applied at 90° collimator angle, the maximum gantry sag was reduced to <0.2 mm. The film measurements at gantry angles of 0° and 180° verified the inferior shift of the radiation fields and the effectiveness of MLC compensation. Conclusions: The results indicate that gantry sag on a linac can be quantitatively measured using a simple phantom and an electronic portal imaging device. Reduction of gantry sag is feasible by applying a gantry angle-specific correction to MLC leaf positions at 90° collimator angle. PMID:22482636

    Between 1952 and 1955, Carl Benson and the US Army Snow, Ice and Permafrost Research Establishment undertook a series of traverses of the Greenland Ice Sheet (GIS). Employing a number of physical measurements, Benson (1962) characterized the GIS via mapping of the spatial distribution of annual net accumulation and classifying the diagenetic glacier facies. Recent advances in remote sensing techniques now provide a number of ways to assess the state of the GIS, but these techniques still require some component of in situ verification. In the springs of 2010 and 2011, we undertook a 1200 km traverse along a nearly-identical route on the GIS from Thule Air Base to Summit Station. Along the traverse route, we characterized the physical stratigraphy of the near-surface (0-10 m depth) snow using an array of observations such as density, grain size, hardness, optical stratigraphy and temperature. We collected a total of 30 snow pits and 14 shallow firn cores over the two field seasons. These measurements allow us to make comparisons with Benson's results, identifying changes in glacier facies and accumulation patterns over the past 55 years. In addition to physical stratigraphy, we measured snowpit chemical stratigraphy (major ions, trace elements and stable water isotopes) at 5-10 cm resolution. These measurements allow us to date horizons seen in the physical stratigraphic record, and to explore questions about the spatial variability of species deposition. Here, we present an initial analysis of these snowpits, shallow cores, and BOS logs, co-located with near infrared imagery, ground-penetrating radar and kinematic GPS data (see Lutz et al. and Overly et al., both this session), which will be useful in quantifying spatial and temporal changes in glacier facies, accumulation rates, and geochemical cycling on the GIS.

    :   Infidum similis Travassos, 1916 (Dicrocoeliidae: Leipertrematinae) was found in the gall bladder of Leptophis diplotropis Günther, 1872 from El Podrido, Acapulco, Guerrero, Mexico. A phylogenetic analysis based on partial sequences of the 28S ribosomal RNA using maximum likelihood (ML) and Bayesian inference (BI) analyses was carried out to assess its phylogenetic position within suborder Xiphidiata, alongside members of the superfamilies Gorgoderoidea and Plagiorchoidea. The phylogenetic trees showed that the genus is most-closely related to the Plagiorchoidea rather than to the Gorgoderoidea, in keeping with previous taxonomic designations. Phylogenies obtained from ML and BI analysis of the 28S rDNA gene revealed a well supported clade in which Choledocystus hepaticus (Lutz, 1928) Sullivan, 1977 is sister to I. similis. On the other hand, a tree obtained using a partial sequence of the cytochrome c oxidase subunit 1 (cox1) mtDNA gene (ML and BI analysis), with species supposed to be closely related to I. similis according to 28S, does not support this relatedness. Based on the independence of Infidum from the subfamily Leipertrematinae Yamaguti, 1958 , our results clearly demonstrated that the genus corresponds to a different family and with species closely related to C. hepaticus within Plagiorchoidea. New data are presented about the tegumental surface of I. similis by scanning electron microscopy as well as the estimation of its haploid genome size using Feulgen Image Analysis Densitometry of sperm nuclei as part of the characterization of this species. This is the first genome size estimated for a member of Plagiorchiida, and these data will provide a new source of knowledge on helminth diversity and evolutionary studies. This constitutes the first host record, and new geographical distribution, for this species in Mexico. PMID:26998629

    We present new absolute trigonometric parallaxes and proper motions for seven Population II variable stars-five RR Lyr variables: RZ Cep, XZ Cyg, SU Dra, RR Lyr, and UV Oct; and two type 2 Cepheids: VY Pyx and {kappa} Pav. We obtained these results with astrometric data from Fine Guidance Sensors, white-light interferometers on Hubble Space Telescope. We find absolute parallaxes in milliseconds of arc: RZ Cep, 2.12 {+-} 0.16 mas; XZ Cyg, 1.67 {+-} 0.17 mas; SU Dra, 1.42 {+-} 0.16 mas; RR Lyr, 3.77 {+-} 0.13 mas; UV Oct, 1.71 {+-} 0.10 mas; VY Pyx, 6.44 {+-} 0.23 mas; and {kappa} Pav, 5.57 {+-} 0.28 mas; an average {sigma}{sub {pi}}/{pi} = 5.4%. With these parallaxes, we compute absolute magnitudes in V and K bandpasses corrected for interstellar extinction and Lutz-Kelker-Hanson bias. Using these RR Lyrae variable star absolute magnitudes, we then derive zero points for M{sub V} -[Fe/H] and M{sub K} -[Fe/H]-log P relations. The technique of reduced parallaxes corroborates these results. We employ our new results to determine distances and ages of several Galactic globular clusters and the distance of the Large Magellanic Cloud. The latter is close to that previously derived from Classical Cepheids uncorrected for any metallicity effect, indicating that any such effect is small. We also discuss the somewhat puzzling results obtained for our two type 2 Cepheids.

    Isocentre verification tests, such as the Winston-Lutz (WL) test, have gained popularity in the recent years as techniques such as stereotactic radiosurgery/radiotherapy (SRS/SRT) treatments are more commonly performed on radiotherapy linacs. These highly conformal treatments require frequent monitoring of the geometrical accuracy of the isocentre to ensure proper radiation delivery. At our clinic, the WL test is performed by acquiring with the EPID a collection of 8 images of a WL phantom fixed on the couch for various couch/gantry angles. This set of images is later analyzed to determine the isocentre size. The current work addresses the acquisition process. A manual WL test acquisition performed by and experienced physicist takes in average 25 minutes and is prone to user manipulation errors. We have automated this acquisition on a Varian TrueBeam STx linac (Varian, Palo Alto, USA). The Varian developer mode allows the execution of custom-made XML script files to control all aspects of the linac operation. We have created an XML-WL script that cycles through each couch/gantry combinations taking an EPID image at each position. This automated acquisition is done in less than 4 minutes. The reproducibility of the method was verified by repeating the execution of the XML file 5 times. The analysis of the images showed variation of the isocenter size less than 0.1 mm along the X, Y and Z axes and compares favorably to a manual acquisition for which we typically observe variations up to 0.5 mm.

    The hylid frog Scinax perpusillus species group comprises 13 species that share, in addition to a few morphological features, reproduction that occurs exclusively associated with bromeliads. Among the species in the group, Scinax v-signatus (Lutz, 1968) is one of the few with a relatively large geographic distribution, occurring in association with bromeliads growing on granitic outcrops above 800 m along the Serra dos Órgãos (a local designation of Serra do Mar) in the Atlantic forest, State of Rio de Janeiro. Here we demonstrate that previous assessment of the distribution of this species was overestimated, and reevaluate the available data on its occurrence. The distributional data analyzed was based on three levels of evidence. First, we assessed the distribution of the bromeliad, Alcantarea imperialis (Carrière) Harms, which is used by S. v-signatus at the type locality. We plotted potential occurrence data for this plant using Google Earth (GE) by visually inspecting GE images in search of indications of granitic outcrops where groups and large individual bromeliads could be identified. Second, we plotted the distribution of these plants and that of the frog based on locality data taken from the literature and voucher specimens in natural history collections and checked for congruence between these sets of data. Third, as a second test of accuracy of this methodology we visited four new localities indicated by the bromeliad-occurrence GE prediction map and searched for the occurrence of both the frog and the bromeliad. This simple process has proven efficient and accurate in finding new collecting sites and determining the distribution of the two involved taxa. We discuss this and other possibilities of using Google Earth as a tool for mapping and discovering the distribution of organisms and habitats. Furthermore, this study has shed light on a more accurate and realistic estimate of the distribution of Scinax v-signatus with implications for the

  8. Dual pathways of internalization of the cholecystokinin receptor

    PubMed Central

    1995-01-01

    Receptor molecules play a major role in the desensitization of agonist- stimulated cellular responses. For G protein-coupled receptors, rapid desensitization occurs via receptor phosphorylation, sequestration, and internalization, yet the cellular compartments in which these events occur and their interrelationships are unclear. In this work, we focus on the cholecystokinin (CCK) receptor, which has been well characterized with respect to phosphorylation. We have used novel fluorescent and electron-dense CCK receptor ligands and an antibody to probe receptor localization in a CCK receptor-bearing CHO cell line. In the unstimulated state, receptors were diffusely distributed over the plasmalemma. Agonist occupation stimulated endocytosis via both clathrin-dependent and independent pathways. The former was predominant, leading to endosomal and lysosomal compartments, as well as recycling to the plasmalemma. The clathrin-independent processes led to a smooth vesicular compartment adjacent to the plasmalemma resembling caveolae, which did not transport ligand deeper within the cell. Potassium depletion largely eliminated clathrin-dependent endocytosis, while not interfering with agonist-stimulated receptor movement into subplasmalemmal smooth vesicle compartments. These cellular endocytic events can be related to the established cycle of CCK receptor phosphorylation and dephosphorylation, which we have previously described (Klueppelberg, U. G., L. K. Gates, F. S. Gorelick, and L. J. Miller. 1991. J. Biol. Chem. 266:2403-2408; Lutz, M. P., D. I. Pinon, L. K. Gates, S. Shenolikar, and L. J. Miller. 1993. J. Biol. Chem. 268:12136-12142). The rapid onset and peak of receptor phosphorylation after agonist occupation correlates best with a plasmalemmal localization, while stimulated receptor phosphatase activity correlates best with receptor residence in intracellular compartments. We postulate that the smooth vesicular compartment adjacent to the plasmalemma functions for

    Stereotactic body radiation therapy (SBRT), due to its high precision for target localizing, has become widely used to treat tumours at various locations, including the lungs. Lung SBRT program was started at our institution a year ago. Eighteen patients with peripheral lesions up to 3 cm diameter have been treated with 48 Gy in 4 fractions. Based on four-dimensional computed tomography (4DCT) simulation, internal target volume (ITV) was delineated to encompass the respiratory motion of the lesion. A margin of 5 mm was then added to create the planning target volume (PTV) for setup uncertainties. There was no expansion from gross tumour volume (GTV) to clinical target volume (CTV). Pinnacle 9.6 was used as the primary treatment planning system. Volumetric modulated arc therapy (VMAT) technique, with one or two coplanar arcs, generally worked well. For quality assurance (QA), each plan was exported to Eclipse 10 and dose calculation was repeated. Dose volume histograms (DVHs) of the targets and organs at risk (OARs) were then compared between the two treatment planning systems. Winston-Lutz tests were carried out as routine machine QA. Patient-specific QA included ArcCheck measurement with an insert, where an ionization chamber was placed at the centre to measure dose at the isocenter. For the first several patients, and subsequently for the plans with extremely strong modulation, Gafchromic film dosimetry was also employed. For each patient, a mock setup was scheduled prior to treatments. Daily pre- and post-CBCT were acquired for setup and assessment of intra-fractional motion, respectively.

  11. Structural basis for the interaction between yeast Spt-Ada-Gcn5 acetyltransferase (SAGA) complex components Sgf11 and Sus1.

    Sus1 is a central component of the yeast gene gating machinery, the process by which actively transcribing genes such as GAL1 become associated with nuclear pore complexes. Sus1 is a component of both the SAGA transcriptional co-activator complex and the TREX-2 complex that binds to nuclear pore complexes. TREX-2 contains two Sus1 chains that have an articulated helical hairpin fold, enabling them to wrap around an extended alpha-helix in Sac3, following a helical hydrophobic stripe. In SAGA, Sus1 binds to Sgf11 and has been proposed to provide a link between SAGA and TREX-2. We present here the crystal structure of the complex between Sus1 and the N-terminal region of Sgf11 that forms an extended alpha-helix around which Sus1 wraps in a manner that shares some similarities with the Sus1-Sac3 interface in TREX-2. However, the Sus1-binding site on Sgf11 is somewhat shorter than on Sac3 and is based on a narrower hydrophobic stripe. Engineered mutants that disrupt the Sgf11-Sus1 interaction in vitro confirm the importance of the hydrophobic helical stripe in molecular recognition. Helix alpha1 of the Sus1-articulated hairpin does not bind directly to Sgf11 and adopts a wide range of conformations within and between crystal forms, consistent with the presence of a flexible hinge and also with results from previous extensive mutagenesis studies (Klöckner, C., Schneider, M., Lutz, S., Jani, D., Kressler, D., Stewart, M., Hurt, E., and Köhler, A. (2009) J. Biol. Chem. 284, 12049-12056). A single Sus1 molecule cannot bind Sgf11 and Sac3 simultaneously and this, combined with the structure of the Sus1-Sgf11 complex, indicates that Sus1 forms separate subcomplexes within SAGA and TREX-2.

  12. A comparison between the bottom-track data of an ADCP and Laserscanning Data

    Simon Lutz Technische Universität München, Hydraulic and Water Resources Engineering, München, Germany Peter Rutschmann Technische Universität München, Hydraulic and Water Resources Engineering, München, Germany A standard Acoustic Doppler Current Profiler (ADCP) is constructed, as the name suggests, to gain data about the flow velocity and discharge of e.g. a river. The device is in fact similar to a sonar and uses the Doppler effect to detect the velocity of particles in the water column below the transducers. Beside that standard function it also can track the bottom of a river or sea. The pulses are scattered by the bottom and the shift in the detected velocities between bottom and bulk phase can be used to identify the surface. However this data set depends on the quality of the signal and can be influenced inter alia when the river-bed is moving. Under in situ conditions it is almost not possible to evaluate the quality of this bottom track data. On the other hand e.g. a minimum water depth is needed to get proper results with the ADCP which causes problems in a lab flume. Therefore a reservoir was used for the comparison measurement which could be drained and set nearby dry so the scanning with a RIEGL terrestrial laser scanner became feasible. Within the reservoir due to sedimentation of silt and fine sand fractions a nature-like bottom structure has developed including a talweg, steeper and more shallow areas. This is a perfect structure for the comparison of the results of these two measurement devices. With the Laser-scanning data a 3D model is generated. The bottom track cross sections of the ADCP can be implemented in this model and compared.

    This article addresses archival methods, techniques, and practices for managing documents generated by scientific activity, using field research carried out at an Instituto Oswaldo Cruz laboratory at the Fundação Oswaldo Cruz as a reference. Based on an analysis combining an archival studies approach with elements of the sociology of science, we believe that the models and instruments of archival knowledge are subordinate to the assumptions of historical research or social memory. They also serve a technical rationality aligned with empirical organization practices that confront the more complex archival reality, leading archival science to negate its foundations and theoretical principles.

    The utilization of wide range spectrometers is a very important feature for the design of optical diagnostics. This paper describes an innovative approach, based on charged coupled device, which allows to analyze different spectral intervals with the same diffraction grating. The spectral interval is varied by changing the position of the entrance slit when the grating is stationary. The optical system can also include a spherical mirror. In this case the geometric position of the mirror is calculated aiming at compensating the first order astigmatism and the meridional coma of the grating. This device is planned to be used in Thomson scattering diagnostic of the TOKAMAK of Instituto Superior Tecnico, Lisbon (ISTTOK).

    South America is responsible for about half of the cassava world production. In the 1970's productivity of the crop on the continent was about 15 ton/ha, and dropped continuously until reaching 12 ton/ha in 2004. India's productivity of cassava increased from 10 ton/ha in the 1970's to 28 ton/ha in 2004. Brazil contributed significantly to improving cassava crops through the Instituto Agronômico de Campinas in the 1960's and 1970's.
