    El presente estudio se desarrolló con el fin de determinar la heredabilidad, en sentido amplio, del rendimiento y sus componentes en tomate y a la vez describir las relaciones genotípicas y ambientales para dichos componentes en una población constituida por tres líneas endocriadas (Ponderosa Red, Chonto y Red Cherry como progenitores y las F1 provenientes de los cruzamientos entre los progenitores en una sola dirección. La heredabilidad se estimó en base a los cuadrados medios esperados del análisis de varianza y las correlaciones genotípicas y ambientales en base a los cuadrados medios esperados del análisis de varianza y productos cruzados medios del análisis de covarianza. Para el rendimiento se estimó una heredabilidad de 79.3%, para el número total de frutos de 93.107%, para peso promedio de de fruto de 4.25%. Los coeficientes de correlación genotípicos estimados fueron: para número de frutos por planta y peso promedio de frutos de -0.985; para número de inflorescencias por planta y número de frutos por inflorescencia de 0,541; para número de lóculos por fruto y peso promedio de lóculos de 0.826. Los coeficientes de correlación ambiental estimados fueron: para número de frutos por planta y peso promedio de frutos de -0.512; para rendimiento y número de frutos por planta de -0.065; para rendimiento y peso promedio de frutos de 0.613; para número de inflorescencias y número de frutos por inflorescencias de -0.878; para número de lóculos por fruto y peso promedio de lóculos de -0.779. Lo anterior indica que el método de mejoramiento para rendimiento, dentro de la población estudiada, seria la selección, tomando como índice de selección apropiado el peso promedio de frutos pero sin descuidar el número de frutos. Se debe maximizar las condiciones favorables de suelo y manejo de cultivo para permitir una adecuada manifestación de los dos componentes primarios del rendimiento.

    Faith-based organizations (FBOs) have been successful in delivering health promotion programs for African Americans, though few studies have been conducted among Latinos. Even fewer have focused on organizational change, which is required to sustain community-based initiatives. We hypothesized that FBOs serving Latinos would be more likely to offer evidence-based strategies (EBS) for cancer control after receiving a capacity enhancement intervention to implement health programs, and designed the CRUZA trial to test this hypothesis. This paper describes the CRUZA design and baseline findings. We identified Catholic parishes in Massachusetts that provided Spanish-language mass (n = 65). A baseline survey assessed organizational characteristics relevant to adoption of health programs, including readiness for adoption, "fit" between innovation and organizational mission, implementation climate, and organizational culture. In the next study phase, parishes that completed the baseline assessment will be recruited to a randomized cluster trial, with the parish as the unit of analysis. Both groups will receive a Program Manual and Toolkit. Capacity Enhancement parishes will also be offered technical support, assistance forming health committees and building inter-institutional partnerships, and skills-based training. Of the 49 parishes surveyed at baseline (75%), one-third (33%) reported having provided at least one health program in the prior year. However, only two program offerings were cancer-specific. Nearly one-fifth (18%) had an active health ministry. There was a high level of organizational readiness to adopt cancer control programs, high congruence between parish missions and CRUZA objectives, moderately conducive implementation climates, and organizational cultures supportive of CRUZA programming. Having an existing health ministry was significantly associated with having offered health programs within the past year. Relationships between health program

    The vestibulocochlear nerve (8th cranial nerve) is a sensory nerve. It is made up of two nerves, the cochlear, which transmits sound and the vestibular which controls balance. It is an intracranial nerve which runs from the sensory receptors in the internal ear to the brain stem nuclei and finally to the auditory areas: the post-central gyrus and superior temporal auditory cortex. The most common lesions responsible for damage to VIII are vestibular Schwannomas. This report reviews the anatomy and various investigations of the nerve. Copyright © 2013.

    The CRUZA randomized trial tested the efficacy of an organizational-level intervention to increase the capacity of Catholic faith-based organizations (FBOs) serving Latinos to implement evidence-based strategies (EBS) for cancer control. Thirty-one Catholic parishes were enrolled. Twenty were randomized to a "capacity enhancement" (CE) intervention and 11 to a "standard dissemination" (SD) condition. Each received a Program Implementation Manual and Toolkit of materials culturally adapted for FBOs with Latino audiences for five types of EBS recommended by the US Preventive Services Community Guide. CE parishes were offered a menu of capacity-building activities over a 3-month period, while SD parishes were provided a one-time consultation by an Intervention Specialist. Baseline and follow-up surveys compared the number and types of EBS offered. At baseline, only one parish had offered any cancer-related program in the prior year, yet a third (36 %) had offered some other type of health program or service. At post-intervention follow-up, all parishes offered a greater number of EBS. The only statistically significant difference between CE and SD groups was the number of parishes offering small media interventions (90 % in CE, 64 % in SD; p support to carry out programming. Further research is needed to examine the extent to which program offerings continued after the period of grant funding. Clinicaltrials.gov NCT01740219 .

    Below 125K, tetragonal ice VIII remains in a metastable form at ambient pressure. This form has long been considered to be identical to ice VIII, although unexplained discrepancies exist between their vibrational spectra. Neutron diffraction studies reveal an isostructural phase transformation below 2GPa related to a weakening of the bonds between the two D 2 O sublattices of ice VIII. In this new phase, ice VIII ' , the tetragonal distortion is 20% larger than in ice VIII, which accounts for the differences between the vibrational frequencies of the two phases. copyright 1997 The American Physical Society

  13. [Ehler-Danlos syndrome type VIII].

    2010-03-01

    Ehlers-Danlos syndrome (EDS) comprises a heterogeneous group of diseases involving genetic collagen fibre impairment. We describe a case of a patient presenting the rare type VIII, in which dermatitis ocre was associated with parodontal disease, and which was diagnosed late. A 29-year-old man consulted for a pretibial ulcer present for seven years, resulting from a post-traumatic haematoma that had failed to heal. In view of the longiliner morphology, it had previously been diagnosed as Marfan syndrome. Subsequently, edentation was observed as well as "alveolar bone fragility". Examination revealed a marfanoid morphotype, a pretibial ulcer set within long-standing bilateral dermatitis ocre and papyraceous scars, but no joint hyperlaxity or cutaneous hyperelasticity. The diagnosis was consequently corrected to EDS type VIII. Type VIII is a rare form of EDS, and the molecular mechanism is poorly understood. The involvement of parodontal connective tissue suggests impairment of collagen I and III proteins. It is important to identify this type of the disease since it involves parodontal disease for which early treatment is required in order to try to prevent edentation. The present case demonstrates the importance of diagnosis, which may be based upon appearance of bilateral dermatitis ocre from the age of 15 years associated with skin fragility. This sign is not part of the classical picture of Marfan syndrome, with which EDS type VIII is often confounded. Copyright 2009 Elsevier Masson SAS. All rights reserved.

  14. Development and characterization of recombinant ovine coagulation factor VIII.

    Full Text Available Animal models of the bleeding disorder, hemophilia A, have been an integral component of the biopharmaceutical development process and have facilitated the development of recombinant coagulation factor VIII (fVIII products capable of restoring median survival of persons with hemophilia A to that of the general population. However, there remain several limitations to recombinant fVIII as a biotherapeutic, including invasiveness of intravenous infusion, short half-life, immunogenicity, and lack of availability to the majority of the world's population. The recently described ovine model of hemophilia A is the largest and most accurate phenocopy. Affected sheep die prematurely due to bleeding-related pathogenesis and display robust adaptive humoral immunity to non-ovine fVIII. Herein, we describe the development and characterization of recombinant ovine fVIII (ofVIII to support further the utility of the ovine hemophilia A model. Full-length and B-domain deleted (BDD ofVIII cDNAs were generated and demonstrated to facilitate greater biosynthetic rates than their human fVIII counterparts while both BDD constructs showed greater expression rates than the same-species full-length versions. A top recombinant BDD ofVIII producing baby hamster kidney clone was identified and used to biosynthesize raw material for purification and biochemical characterization. Highly purified recombinant BDD ofVIII preparations possess a specific activity nearly 2-fold higher than recombinant BDD human fVIII and display a differential glycosylation pattern. However, binding to the carrier protein, von Willebrand factor, which is critical for stability of fVIII in circulation, is indistinguishable. Decay of thrombin-activated ofVIIIa is 2-fold slower than human fVIII indicating greater intrinsic stability. Furthermore, intravenous administration of ofVIII effectively reverses the bleeding phenotype in the murine model of hemophilia A. Recombinant ofVIII should facilitate

    Introduction Hemophilia A individuals displaying a similar genetic defect have heterogeneous clinical phenotypes. Aim To evaluate the underlying effect of exogenous factor (f)VIII on tissue factor (Tf)-initiated blood coagulation in severe hemophilia utilizing both empirical and computational models. Methods We investigated twenty-five clinically severe hemophilia A patients. All individuals were on fVIII prophylaxis and had not received fVIII from 0.25 to 4 days prior to phlebotomy. Coagulation was initiated by the addition of Tf to contact-pathway inhibited whole blood ± an anti-fVIII antibody. Aliquots were quenched over 20 min and analyzed for thrombin generation and fibrin formation. Coagulation factor levels were obtained and used to computationally predict thrombin generation with fVIII set to either zero or its value at the time of the draw. Results Due to prophylactic fVIII, at the time of the blood draw, the individuals had fVIII levels that ranged from hemophilia A. The combination of each individual's coagulation factors (outside of fVIII) determine each individual's baseline thrombin potential and may affect bleeding risk. PMID:21899664

    The spectrum of Xe VIII has been observed in a theta-pinch discharge. New line identifications were made that determine the energies of the 6s, 7s, 6p, and 5f terms relative to the 5s 2 S ground state and confirm the previously known 5p and 5d terms. An independent system of levels derived from the observed 4f-ng (n = 5,6) transitions was found. Its position relative to the ground state is obtained from a predicted value for the 5g effective quantum number n*. From the ns series (n=5--7) a value for the ionization enegy of 105.91 +- 0.05 eV was derived

    This special issue includes invited and selected articles of the VIII Brazilian Meeting on Simulational Physics (BMSP), held in Florianópolis, Santa Catarina, Brazil, from 3rd to 8th August, 2015. This is the eighth such meeting, and the second one to have contributed papers published in Journal of Physics: Conference Series (the other was the VII BMSP). The previous meetings in the BMSP series took place in the mountains of Minas Gerais, in the region of the Brazilian Pantanal, and in the shores of Paraíba. Now, for the first time, the Meeting was held in Florianópolis, with its pleasing shores, the capital of Santa Catarina state. The VIII BMSP brought together about 50 researchers from all over the world for a vibrant and productive conference. As in the previous meetings, the talks and posters highlighted recent advances in applications, algorithms, and implementation of computer simulation methods for the study of condensed matter, materials, and out of equilibrium, quantum and biologically motivated systems. We are sure that this meeting series will continue to be an important occasion for people working in simulational physics to exchange ideas and discuss the state of the art of this always expanding field. We are very glad to put together this special issue, and are most appreciative of the efforts of the editors of the Journal of Physics: Conference Series for making this publication possible. We are grateful for the outstanding work of the Florianopolis team, for the financial support of the Brazilian agencies CAPES and CNPq, and of the Federal Universities UFPB and UFSC. At last, but not least, we would like to acknowledge all of the authors for their written submissions. (paper)

    There is growing research interest into the etiologies of cryptogenic stroke, in particular as it relates to hypercoagulable states. An elevation in serum levels of the procoagulant factor VIII is recognized as one such culprit of occult cerebral infarctions. It is the objective of the present review to summarize the molecular role of factor VIII in thrombogenesis and its clinical use in the diagnosis and prognosis of acute ischemic stroke. We also discuss the utility of screening for serum factor VIII levels among patients at risk for, or those who have experienced, ischemic stroke. © The Author(s) 2015.

Propuesto primero como ciencia ha llegado a ser claramente rechazado por posteriores ambientes científicos. Tendría interés hacer una historia social del folklore. Este artículo sugiere que tales paradojas y contradicciones están relacionadas con el paradigma científico que asumieron sus promotores, el evolucionismo cultural y con un concepto idealizado de "pueblo", que ayudaron a construir presentando colecciones de materiales. También analiza las diferentes funciones sociales que ha cumplido el discurso folklórico.

    Patients with hemophilia A rely on exogenous factor VIII to prevent bleeding in joints, soft tissue, and the central nervous system. Although successful gene transfer has been reported in patients with hemophilia B, the large size of the factor VIII coding region has precluded improved outcomes with gene therapy in patients with hemophilia A. We infused a single intravenous dose of a codon-optimized adeno-associated virus serotype 5 (AAV5) vector encoding a B-domain-deleted human factor VIII (AAV5-hFVIII-SQ) in nine men with severe hemophilia A. Participants were enrolled sequentially into one of three dose cohorts (low dose [one participant], intermediate dose [one participant], and high dose [seven participants]) and were followed through 52 weeks. Factor VIII activity levels remained at 3 IU or less per deciliter in the recipients of the low or intermediate dose. In the high-dose cohort, the factor VIII activity level was more than 5 IU per deciliter between weeks 2 and 9 after gene transfer in all seven participants, and the level in six participants increased to a normal value (>50 IU per deciliter) that was maintained at 1 year after receipt of the dose. In the high-dose cohort, the median annualized bleeding rate among participants who had previously received prophylactic therapy decreased from 16 events before the study to 1 event after gene transfer, and factor VIII use for participant-reported bleeding ceased in all the participants in this cohort by week 22. The primary adverse event was an elevation in the serum alanine aminotransferase level to 1.5 times the upper limit of the normal range or less. Progression of preexisting chronic arthropathy in one participant was the only serious adverse event. No neutralizing antibodies to factor VIII were detected. The infusion of AAV5-hFVIII-SQ was associated with the sustained normalization of factor VIII activity level over a period of 1 year in six of seven participants who received a high dose, with

    Full Text Available Objective. We present the case of a 73-year-old female, with no family or personal history of a bleeding disorder, who had a classic presentation for acquired hemophilia A. Factor VIII activity was low but detectable and a factor VIII inhibitor was undetectable. Methods. The patient’s plasma was comprehensively studied to determine the cause of the acquired coagulopathy. Using the Nijmegen modification of the Bethesda assay, no factor VIII autoantibody was measureable despite varying the incubation time from 1 to 3 hours. Results. The aPTT was prolonged at 46.8 seconds, which did not correct in the 4 : 1 mix but did with 1 : 1 mix. Using a one stage factor VIII activity assay, the FVIII activity was 16% and chromogenic FVIII activity was also 16%. The patient was treated with recombinant FVII and transfusion, significantly reducing bleeding. Long-term therapy was initiated with cyclophosphamide and prednisone with normalization of FVIII activity. Conclusions. Physicians can be presented with the challenging clinical picture of an acquired factor VIII inhibitor without a detectable inhibitor by the Bethesda assay. Standard therapy for an acquired hemophilia A should be considered.

    The Physicist Engineering is a multidisciplinary profession in which an undergraduate student integrates and applies their knowledge of Physics, Mathematics, and Computing to adapt and innovate all kind of technologies, as well as to development and apply theoretical knowledge to different fields of science and engineering. A Physicist Engineer, supported by a solid preparation in science and engineering is available to study, analyze, identify, and solve problems in different fields of science and technology for industries, hospitals, research laboratories, institutes and governmental organizations focused on metrology, optics, energy, materials, instrumentation of sophisticated equipment. The Physicist Engineering bachelor degree is a national and international reference to encouraging all those students to apply knowledge through active participation in the operation, planning, and management of projects. The technological and scientific impact of a Physicist Engineering undergraduate and graduate students, as well as the tutorial of the research professor that are interested in Physics and Physics Engineering, may be found in a biennial event like the International Conference on Physicist Engineering, through the diffusion of both experimental and theoretical research and teaching. In order to promote and encourage strength academic goals among universities and research institutions, the International Conference on Physics Engineering Committee, integrated by a faculty meeting of the Universidad Autónoma Metropolitana, Campus Azcapotzalco, has decided to grant the VIII International Congress of Physics Engineering to the Universidad Autónoma de Yucatán, which is going to take place on Mérida, November 7 th to 11 th , 2016. This conference considers different topics as: Renewables Energies Engineering Materials Technology Nanotechnology Medical Physics Education in Physics Engineering Nuclear Engineering High Precision Instrumentation Atmosphere Physics

    We here present the case of a 70-year-old woman referred to our unit for investigation of bleeding. Investigations confirmed a high titre acquired Factor VIII inhibitor. In association there was relapse of systemic illness associated with anti-neutrophil cytoplasmic antibodies (atypical pattern) for which she had been treated five years previously. Immunosuppression was attempted, but it failed to have an impact both on the inhibitor titre and on the underlying disorder. The patient died from multi-organ failure and massive chest hemorrhage. Post-mortem showed necrotizing vasculitis of medium sized vessels at several sites, including the kidney, consistent with a diagnosis of polyarteritis nodosa. Although it is well recognised that Factor VIII inhibitors are found in conjunction with autoimmune disorders, this case is significant in that it is the first associated with histologically proven polyarteritis nodosa type vasculitis. The case illustrates the difficulties in the investigation and management of patients with acquired high titre Factor VIII inhibitors.

    Joshi et al. (1984) have conducted an analysis of the 3d8 4s-3d8 4p transitions in As VII. The present investigation is concerned with an analysis of similar transitions in Se VIII. The selenium spectrum was photographed in the 400-1200-A wavelength region on a variety of normal-incidence spectrographs. Attention is given to least-squares-fit (LSF) and Hartree-Fock (HF) parameter values for the 3d9 4d configuration of Se VII, LSF and HF parameter values for the 3d8 4s and 3d8 4p configurations of Se VIII, the energy and composition of the levels of the 3d9 4d configuration of Se VII, classified lines in Se VII, energy levels and composition of the 3d8 4s configuration and the revised and newly determined levels of the 3d8 4p configuration of Se VIII, and newly classified lines of Se VIII. 15 references

    Lymphatic vascular endothelium both on tissue section and in culture exhibits positivity for Factor VIII-associated antigen although staining is generally less intense and more spotty than in comparable blood vascular endothelium. Lymphatic endothelium also exhibits Weibel-Palade bodies. Neither marker, therefore, reliably distinguishes blood vascular endothelium from lymphatic endothelium.

    Capillary light sources were used to observe the spectrum of seven-times-ionized xenon, XeVIII, in the 300-6000 A wavelength range. Twenty-eight energy levels belonging to the 5s-9s, 5d-9d, 5g-9g, 7i-10i, 9l, 5p-9p, 4f-9f, 6h-9h and 8k-10k configurations were adjusted and 38 new spectral lines were classified. The XeVIII ionization energy was determined with improved accuracy using the polarization model. The analysis was supported by Hartree-Fock calculations. The weighted oscillator strengths for all the observed spectral lines were also calculated considering the fitted values for the energy parameters

    Hassium, element 108, was produced in the fusion reaction between 26 Mg and 248 Cm. The hassium recoils were oxidized in-situ to a highly volatile oxide, presumably HsO 4 , and were transported in a mixture of He and O 2 to a deposition and detection system. The latter consisted of 16 silicon PIN-photodiodes facing a layer of NaOH, which served, in the presence of a certain partial pressure of water in the transport gas, as reactive surface for the deposition of the volatile tetroxides. Six correlated α-decay chains of Hs were detected in the first 5 detectors centred around detection position 3. In analogy to OsO 4 , which forms Na 2 [OsO 4 (OH) 2 ], an osmate(VIII), with aqueous NaOH, HsO 4 presumably was deposited as Na 2 [HsO 4 (OH) 2 ], a hassate(VIII). (orig.)

  14. Henry VIII, McLeod syndrome and Jacquetta's curse.

    2013-01-01

    The mental decline of King Henry VIII from being a jovial, charismatic and athletic young man into an increasingly paranoid, brutal tyrant in later life, ever more concerned at his lack of one or more male heirs, has attracted many medical diagnostic theories. Previous hypotheses have included diabetes, syphilis and hypothyroidism, among others. However, these inadequately explain Henry's failure to produce a male heir, despite multiple pairings. The latest postulated diagnoses for Henry are the coexistence of both Kell blood group antigenicity (possibly inherited from Jacquetta Woodville, Henry's maternal great grandmother) causing related impaired fertility, and McLeod syndrome, causing psychotic changes. As the mutated McLeod protein of the syndrome significantly reduces the expression, effectively inactivating the Kell antigen, we critically review this theory, examining in detail the pathophysiology of these conditions and assessing the genealogy of Henry VIII and its effect in subsequent generations.

    1993-01-01

    The spectrum of seven times ionized sulfur, S VIII, has been observed in the wavelength range 50-1200 A. Both beam-foil and laser-produced plasma light sources have been used. 71 new lines representing the transitions 2p 5 -2p 4 3d, 2p 4 3s-3p, 3p-3d, 3d-4f, 4f-5g and 5g-6h have been identified and 100 energy levels, of which 46 are new, are now accurately established. The spectral analysis is supported by isoelectronic comparisons along the F I-sequence and by parametric least-squares fits of Slater integrals to the observed levels. The ionization potential in S VIII is determined to 2 651 899 ± 60 cm -1 and estimated ionization energies are derived for the isoelectronic elements between F I and Ar X. (orig.)

  17. Progress toward inducing immunologic tolerance to factor VIII

    Scott, David W.; Pratt, Kathleen P.; Miao, Carol H.

    2013-01-01

    A major problem in treating hemophilia A patients with therapeutic factor VIII (FVIII) is that 20% to 30% of these patients produce neutralizing anti-FVIII antibodies. These antibodies block (inhibit) the procoagulant function of FVIII and thus are termed “inhibitors.” The currently accepted clinical method to attempt to eliminate inhibitors is immune tolerance induction (ITI) via a protocol requiring intensive FVIII treatment until inhibitor titers drop. Although often successful, ITI is ext...

  18. Characterization of five partial deletions of the factor VIII gene

    Youssoufian, H.; Antonarakis, S.E.; Aronis, S.; Tsiftis, G.; Phillips, D.G.; Kazazian, H.H. Jr.

    1987-01-01

    Hemophilia A is an X-linked disorder of coagulation caused by a deficiency of factor VIII. By using cloned DNA probes, the authors have characterized the following five different partial deletions of the factor VIII gene from a panel of 83 patients with hemophilia A: (i) a 7-kilobase (kb) deletion that eliminates exon 6; (ii) a 2.5-kb deletion that eliminates 5' sequences of exon 14; (iii) a deletion of at least 7 kb that eliminates exons 24 and 25; (iv) a deletion of at least 16 kb that eliminates exons 23-25; and (v) a 5.5-kb deletion that eliminates exon 22. The first four deletions are associated with severe hemophilia A. By contrast, the last deletion is associated with moderate disease, possibly because of in-frame splicing from adjacent exons. None of those patients with partial gene deletions had circulating inhibitors to factor VIII. One deletion occurred de novo in a germ cell of the maternal grandmother, while a second deletion occurred in a germ cell of the maternal grandfather. These observations demonstrate that de novo deletions of X-linked genes can occur in either male or female gametes

  19. Chromogenic Factor VIII Assays for Improved Diagnosis of Hemophilia A.

    2017-01-01

    Hemophilia A is an inherited bleeding disorder caused by a reduced level of factor VIII coagulant activity (FVIII:C) in blood. Bleeding episodes may occur spontaneously in the severe form of hemophilia or after trauma in the milder forms. It is important that patients are diagnosed correctly, which includes placing them into the correct severity category of the disorder so that appropriate treatment can be given. Diagnosis is made by determination of the amount of FVIII:C in the blood, usually using a one-stage factor VIII:C assay. However, approximately one third of patients with mild or moderate hemophilia will have much lower results by the chromogenic assay, with some of them having normal results by the one-stage assay. The chromogenic factor VIII assay is used in some specialized hemophilia reference centers and is recommended for the diagnosis of mild hemophilia A, as this assay is considered to better reflect the severity status of hemophilia patients than the one-stage assay.

  20. Ehlers-Danlos Syndrome Type VIII: A Rare Cause of Leg Ulcers in Young Patients

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Ehlers-Danlos syndrome type VIII (EDS-VIII is a very rare autosomal dominant disease characterized by early-onset periodontitis associated with features of Ehlers-Danlos syndrome. We report a 32-year-old man whose chronic leg ulcer led to the diagnosis of EDS-VIII. He had severe periodontitis with complete loss of permanent teeth and skin fragility with thin skin, atrophic scars, and brownish atrophic pretibial plaques. Leg ulcer is not a prominent feature of EDS-VIII. We suggest adding EDS-VIII to the list of rare diseases accounting for chronic leg ulcers, if this case report prompts others to report leg ulcers associated with EDS-VIII.

  1. Differential proteolytic activation of factor VIII-von Willebrand factor complex by thrombin

    International Nuclear Information System (INIS)

    Hill-Eubanks, D.C.; Parker, C.G.; Lollar, P.

    1989-01-01

    Blood coagulation factor VIII (fVIII) is a plasma protein that is decreased or absent in hemophilia A. It is isolated as a mixture of heterodimers that contain a variably sized heavy chain and a common light chain. Thrombin catalyzes the activation of fVIII in a reaction that is associated with cleavages in both types of chain. The authors isolated a serine protease from Bothrops jararacussu snake venom that catalyzes thrombin-like heavy-chain cleavage but not light-chain cleavage in porcine fVIII as judged by NaDodSO 4 /PAGE and N-terminal sequence analysis. Using a plasma-free assay of the ability of activated 125 I-fVIII to function as a cofactor in the activation of factor X by factor IXa, they found that fVIII is activated by the venom enzyme. The venom enzyme-activated fVIII was isolated in stable form by cation-exchange HPLC. von Willebrand factor inhibited venom enzyme-activated fVIII but not thrombin-activated fVIII. These results suggest that the binding of fVIII to von Willebrand factor depends on the presence of an intact light chain and that activated fVIII must dissociate from von Willebrand factor to exert its cofactor effect. Thus, proteolytic activation of fVIII-von Willebrand factor complex appears to be differentially regulated by light-chain cleavage to dissociate the complex and heavy-chain cleavage to activate the cofactor function

    The research into new materials with good thermoelectric properties has revealed new compounds consisting of metallic elements (Bando Y, Suemitsu T, Takagi K, Tokushima H, Echizen Y, Katoh K, Umeo K, Maeda Y and Takabatake T 2000 J. Alloys Compounds 313 1-6, Ghelani N, Loo S, Chung D, Sportouch S, Nardi S, Kanatzidis M, Hogan T and Nolas G 2000 Mater. Res. Soc. 626 Z8.6.1). The half-Heusler compound ZrNiSn, in particular, shows promising thermoelectric properties and has been studied by many scientists during recent years (Uher C, Hu S, Yang J, Meisner G P and Morelli D T 1997 Proc. ICT'97: 16th Int. Conf. on Thermoelectrics pp 485-8, Romaka L P, Stadnyk Yu V, Goryn A M, Gorelenko Yu K and Skolozdra R V 1997 Proc. ICT'97: 16th Int.

Matter 11 1697-709, Oestreich J, Kaefer W, Richardt F, Probst U and Bucher E 1999 Proc. 5th European Workshop on Thermoelectrics pp 192-5). In an effort to find new thermoelectric materials, the half-Heusler compounds of the groups ScM{sup VIII}Sb and YM{sup VIII}Sb (M{sup VIII} = Ni, Pd, Pt) were synthesized by arc melting and the thermoelectric properties were examined by standard characterization methods. Doping experiments showed that it is possible to change the electrical properties of the compounds while retaining the half-Heusler structure. Within the two groups, YPtSb showed the best thermoelectrical properties. At a temperature of 400 K the electrical conductivity of YPtSb is 748{omega}{sup -1} cm{sup -1} and the Seebeck coefficient is 116.3{mu}V K{sup -1}. The thermal conductivity at 400 K extrapolated using the Wiedemann-Franz law is 2.87 W K{sup -1} m{sup -1}. This leads to a dimensionless figure of merit of 0.14.

Twenty new transitions have been classified and eleven new excited-state energies have been determined within the n=4 --7 shells. The ionization potential is derived to be 1 015 800 +- 200 cm -1 . The excited-state energies and fine structures are compared with recent relativistic Hartree-Fock calculations. The 4p-state lifetime has been measured by performing a simultaneous analysis of decay data for the 4p level and for its dominant cascade-repopulating levels. The 4p lifetime is found to be 30% shorter than previously measured values and is in excellent agreement with the result of a recent multiconfiguration Hartree-Fock calculation. The source of the discrepancy between this result and earlier measurements is discussed

  3. Agnostic stacking of intergalactic doublet absorption: measuring the Ne VIII population

    We present a blind search for doublet intergalactic metal absorption with a method dubbed `agnostic stacking'. Using a forward-modelling framework, we combine this with direct detections in the literature to measure the overall metal population. We apply this novel approach to the search for Ne VIII absorption in a set of 26 high-quality COS spectra. We probe to an unprecedented low limit of log N>12.3 at 0.47≤z ≤1.34 over a path-length Δz = 7.36. This method selects apparent absorption without requiring knowledge of its source. Stacking this mixed population dilutes doublet features in composite spectra in a deterministic manner, allowing us to measure the proportion corresponding to Ne VIII absorption. We stack potential Ne VIII absorption in two regimes: absorption too weak to be significant in direct line studies (12.3 13.7). We do not detect Ne VIII absorption in either regime. Combining our measurements with direct detections, we find that the Ne VIII population is reproduced with a power-law column density distribution function with slope β = -1.86 ^{+0.18 }_{ -0.26} and normalization log f_{13.7} = -13.99 ^{+0.20 }_{ -0.23}, leading to an incidence rate of strong Ne VIII absorbers dn/dz =1.38 ^{+0.97 }_{ -0.82}. We infer a cosmic mass density for Ne VIII gas with 12.3 value significantly lower that than predicted by recent simulations. We translate this density into an estimate of the baryon density Ωb ≈ 1.8 × 10-3, constituting 4 per cent of the total baryonic mass.

    The existence of Pu(VIII) was shown in alkaline solutions and in nonpolar solvents (CCl{sub 4} and CHCl{sub 3}) on the ground of such experimental facts like extraction of plutonium species, obtained by means of ozonization of Pu(VI) alkaline solutions into CCl{sub 4} and CHCl{sub 3}; volatility of Pu compounds out of aqueous alkaline solutions, and the mentioned solvents. The product of interaction between PuO{sub 3}.0.8H{sub 2}O and XeF{sub 2} in CCl{sub 4} and CHCl{sub 3} was of the same chemical form for both cases and identical with the form of the product of volatility of Pu out of these organic solutions. The electronic absorbance spectra of these products in CCl{sub 4} and CHCl{sub 3} were fairly similar to the ones for OsO{sub 4} and RuO{sub 4}. The band of absorption in these spectra with the maximum at 332 nm corresponds to the charge transfer of metal-ligand type [π(O)→Pu], as the value of molar extinction coefficient e was found to be higher than 2 x 10{sup 3} L/mole cm. A satisfactory agreement between the energies for the transitions of PuO{sub 4} molecule designed by X{sub α}-SW method and experimental data was observed. A similar accordance was observed for the designed vibration frequency (DFT-method) with the one found as result of analysis of the vibration structure of the experimental spectra. (orig.)

    Plants have two classes of myosins. While recent work has focused on class XI myosins showing that myosin XI is responsible for organelle motility and cytoplasmic streaming, much less is known about the role of myosin VIII in plant growth and development. We have used a combination of RNAi and insertional knockouts to probe myosin VIII function in the moss Physcomitrella patens. We isolated Δmyo8ABCDE plants demonstrating that myosin VIII is not required for plant viability. However, myosin VIII mutants are smaller than wild-type plants in part due to a defect in cell size. Additionally, Δmyo8ABCDE plants produce more side branches and form gametophores much earlier than wild-type plants. In the absence of nutrient media, Δmyo8ABCDE plants exhibit significant protonemal patterning defects, including highly curved protonemal filaments, morphologically defective side branches, as well as an increase in the number of branches. Exogenous auxin partially rescues protonemal defects in Δmyo8ABCDE plants grown in the absence of nutrients. This result, together with defects in protonemal branching, smaller caulonemal cells, and accelerated development in the Δmyo8ABCDE plants, suggests that myosin VIII is involved in hormone homeostasis in P. patens.

    Full Text Available ABSTRACT OBJECTIVES: The capacity of a human cell line to secrete recombinant factor VIII with a F309S point mutation was investigated, as was the effect of the addition of chemical chaperones (betaine and sodium-4-phenylbutyrate on the secretion of factor VIII. METHODS: This work used a vector with a F309S mutation in the A1 domain to investigate FVIII production in the HEK 293 human cell line. Factor VIII activity was measured by chromogenic assay. Furthermore, the effects of chemical drugs on the culture were evaluated. RESULTS: The addition of the F309S mutation to a previously described FVIII variant increased FVIII secretion by 4.5 fold. Moreover, the addition of betaine or sodium-4-phenylbutyrate increased the secretion rate of FVIIIΔB proteins in HEK 293 cells, but the same effect was not seen for FVIIIΔB-F309S indicating that all the recombinant protein produced had been efficiently secreted. CONCLUSION: Bioengineering factor VIII expressed in human cells may lead to an efficient production of recombinant factor VIII and contribute toward low-cost coagulation factor replacement therapy for hemophilia A. FVIII-F309S produced in human cells can be effective in vivo.

    To provide the US nuclear industry with a uniform implementation of the Performance Demonstration requirements within the 1989 edition of ASME Section XI, Appendix VIII, representatives from all US nuclear utilities formed the Performance Demonstration Initiative (PDI). The PDI recognized the potential benefits that Appendix VIII offered the nuclear industry and initiated a proactive approach to implement the requirements. In doing so it was expected that performance demonstration of ultrasonic examination procedures would allow for improvement in the efficiency and credibility of inservice inspection to be realized. Explicit within the performance demonstration requirements of Appendix VIII is the need for a Performance Demonstration Administrator, a difficult requirement to fulfill. Not only must the administrator exhibit the attributes of understanding the demonstration requirements, but also have solid technical knowledge, integrity and be able to interface with the industry at all levels, from operations to regulatory. For the nuclear industry, the EPRI NDE Center is an obvious choice to fulfill this position. This paper provides a brief background of the PDI, a nuclear industry-wide initiative to implement the performance demonstration requirements of Appendix VIII. Even though the consensus approach adopted by the PDI is discussed, the paper's primary objective is to provide examples of the lessons learned by the Center through the specific requirements of Appendix VIII

    Antibody formation to factor VIII (FVIII) remains the greatest clinical and diagnostic challenge to the haemophilia-treating physician. Current guidance for testing for inhibitory FVIII antibodies (inhibitors) recommends the functional Nijmegen-Bethesda assay (NBA). A FVIII ELISA offers a complementary, immunological approach for FVIII antibody testing. It was the aim of this study to retrospectively evaluate the performance of a FVIII ELISA (index) for detection of FVIII antibodies, compared with the NBA (reference). All samples sent for routine FVIII antibody testing at two haemophilia Comprehensive Care Centres, were tested in parallel using the NBA and a solid-phase, indirect FVIII ELISA kit (Immucor). A total of 497 samples from 239 patients (severe haemophilia A=140, non-severe haemophilia A=85, acquired haemophilia A=14) were available for analysis. Sixty-three samples tested positive by the NBA (prevalence 12.7%, 95% confidence interval [CI], 9.9-15.9 %), with a median inhibitor titre of 1.2 BU/ml (range 0.7-978.0). The FVIII ELISA demonstrated a specificity of 94.0% (95%CI, 91.3-96.0), sensitivity of 77.8% (95%CI, 65.5-87.3), negative predictive value of 96.7% (95%CI, 94.5-98.2), positive predictive value 65.3% (95%CI, 53.5-76.0), negative likelihood ratio 0.2 (95%CI, 0.1-0.4), positive likelihood ratio 13.0 (95%CI, 8.7-19.3) and a diagnostic odds ratio of 54.9 (95%CI, 27.0-112.0). Strong positive correlation (r=0.77, pNBA (log adjusted) and FVIII ELISA optical density. In conclusion, FVIII ELISA offers a simple, specific, surveillance method enabling batch testing of non-urgent samples for the presence of FVIII antibodies.

    Hemophilia A is a hereditary X-linked recessive disease caused by mutations in the gene encoding factor VIII (FVIII), occurring in 1 out of 10,000 persons. Life expectancy and quality of life have dramatically improved recently in patients with hemophilia. Chronic kidney disease and need for renal replacement therapy in these patients are rare. The development of inhibitors to FVIII is the most serious complication of hemophilia and makes treatment of bleeds very challenging. We describe here a 28-year-old male patient with severe hemophilia A with presence of factor VIII inhibitor, who had end stage renal disease. Central venous access device was inserted along with infusion of factor eight inhibitor bypass activity before and after the procedure. He is currently on thrice weekly hemodialysis and doing well for 6 months without bleeding episodes. To our knowledge, hemophilia A with factor VIII inhibitor managed with hemodialysis has not been reported so far. © 2016 International Society for Hemodialysis.

    Spectrophotometric determination of hydrogen peroxide was accomplished with osmium(VIII) and m-carboxyphenylfluorone (MCPF) in the presence of cetyltrimethylammonium chloride (CTAC). In the determination of hydrogen peroxide based on the fading of the color of osmium(VIII)-MCPF complex, Beer's law was obeyed in the range 20-406 ng mL(-1), with an effective molar absorption coefficient (at 580 nm) of 5.21×10(4) L mol(-1) cm(-1) and a relative standard deviation of 0.33% (n=6). Further, we performed the characterization of MCPF and obtained the crystal structure. Copyright © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Extensor tendon injuries are widely believed to be straightforward problems that are relatively simple to manage. However, these injuries can be complex and demand a thorough understanding of anatomy to achieve the best functional outcomes. When lacerations occur in the forearm as in Zones VIII and IX injury, the repair of the extensor tendon and muscle, and posterior interosseous nerve (PIN is often challenging. A review of the literature shows little guidance and attention for these injuries. We present four patients with injuries to Zones VIII and IX as well as a review of surgical technique, postoperative rehabilitation, and pearls that may be of benefit to those managing these injuries.

    Hemophilia A is a common X-linked recessive disorder of bleeding caused by deleterious mutations in the gene for clotting factor VIII. The large size of the factor VIII gene, the high frequency of de novo mutations and its tissue-specific expression complicate the detection of mutations. We have used a combination of RT-PCR of ectopic factor VIII transcripts and genomic DNA-PCRs to amplify the entire essential sequence of the factor VIII gene. This is followed by chemical mismatch cleavage analysis and direct sequencing in order to facilitate a comprehensive search for mutations. We describe the characterization of nine potentially pathogenic mutations, six of which are novel. In each case, a correlation of the genotype with the observed phenotype is presented. In order to evaluate the pathogenicity of the five missense mutations detected, we have analyzed them for evolutionary sequence conservation and for their involvement of sequence motifs catalogued in the PROSITE database of protein sites and patterns.

    Inherited combined factor V and factor VIII deficiency (F5F8D) is autosomal recessive transmission disorder. Epistaxis, postsurgical bleeding, and menorrhagia are the most common symptoms. The risk of miscarriage and placental abruption is consequent. We report a case of successful pregnancy in a patient with F5F8D. 20-year-old woman, born of consanguineous parents, third gestate, first parity, two miscarriages, admitted for child birth of a spontaneous pregnancy estimated at 38 weeks and was diagnosed with F5F8D. At admission, patient was hemodynamically stable, with good obstetric conditions. The biologic results showed low levels of PT (52%), factor V (7%), and factor VIII (5%), and the activated partial thromboplastin time was prolonged (68,6%). Parturient was admitted in intensive care unit, maternal and fetal monitoring was performed. Fresh frozen plasma (FFP) and factor VIII concentrates were perfused at the induction of labor. Analgesia used fentanyl titration. The delivery gave birth to a newborn male, with Apgar 10/10 and 3000 g. The puerperium was simple without any important bleeding. Laboratory tests for the newborn were acceptable. Little literature is available on this subject and there are no guidelines available concerning pregnancy; we chose to prescribe a combination of factor VIII concentrate and FFP in pre-, per- and postpartum. The same protocol was successfully used in a patient before dental extraction and prostatectomy. Vaginal delivery is possible, as our case. Management by multidisciplinary team is recommended.

    Vestibular schwannomas and meningiomas account for the great majority of lesions arising in the cerebellopontine angle (CPA). In this report, we present a case of glioneuronal heterotopia, also known as glioneuronal hamartoma, arising from the VIII cranial nerve, which is an extremely uncommon lesion. Important radiologic and surgical aspects are reviewed, which may help in early recognition and intraoperative decision making when these lesions are encountered. A healthy 29-year-old female presented with intermittent right facial numbness. Magnetic resonance imaging (MRI) showed an incidental minimally enhancing cerebellopontine angle lesion on the right VII-VIII cranial nerve complex. The patient declined serial observation and opted for operative intervention for resection. Intraoperatively, the lesion resembled neural tissue and was continuous with the VIII cranial nerve. Pathological analysis demonstrated mature glioneuronal tissue consistent with hamartomatous brain tissue. The patient maintained normal hearing and facial nerve function after surgery. Radiologic, surgical and pathological characteristics are described. Ectopic glioneuronal tissue of the VIII cranial nerve is a rare non-neoplastic lesion, and should be considered in the differential diagnosis of unusual appearing intracanalicular and cerebellopontine angle lesions. The congenital and benign nature of this entity makes observation a valid option for these cases, although they are so infrequent that they are often presumptively managed as vestibular schwannomas. Attempts to radically resect these lesions may result in higher rates of hearing loss or facial palsy due to their continuity with the cranial nerves. Copyright © 2018 Elsevier Inc.

    Administration of factor VIII (F VIII) concentrates by continuous infusion is now routinely used at several haemophilia centers but almost exclusively for hospitalized patients. We evaluated various aspects of home therapy with continuous infusion of an immunoaffinity purified F VIII concentrate (Monoclate P®, Armour) in patients who would normally have been treated with high doses in bolus injections or with continuous infusion as in-patients. Twenty haemophilia A patients, eight after minor surgery and 12 for serious haemorrhage, received continuous infusion with undiluted F VIII by a minipump for a mean of 0.9 days in the hospital, followed by 3.3 days at home. Infusion bags were exchanged every 2.5 days. No haemorrhagic complications occurred, and five haemorrhages that had been resistant to treatment with bolus injections responded promptly to the continuous infusion. There were no technical problems and patient compliance and acceptance was good. We find this mode of therapy safe, efficacious and convenient for the patients as well as for the staff.

  6. Specific membrane binding of factor VIII is mediated by O-phospho-L-serine, a moiety of phosphatidylserine.

    Phosphatidylserine, a negatively charged lipid, is exposed on the platelet membrane following cell stimulation, correlating with the expression of factor VIII receptors. We have explored the importance of the negative electrostatic potential of phosphatidylserine vs chemical moieties of phosphatidylserine for specific membrane binding of factor VIII. Fluorescein-labeled factor VIII bound to membranes containing 15% phosphatidic acid, a negatively charged phospholipid, with low affinity compared to phosphatidylserine-containing membranes. Binding was not specific as it was inhibited by other proteins in plasma. Factor VIII bound to membranes containing 10% phosphatidylserine in spite of a varying net charge provided by 0-15% stearylamine, a positively charged lipid. The soluble phosphatidylserine moiety, O-phospho-L-serine, inhibited factor VIII binding to phosphatidylserine-containing membranes with a Ki of 20 mM, but the stereoisomer, O-phospho-D-serine, was 5-fold less effective. Furthermore, binding of factor VIII to membranes containing synthetic phosphatidyl-D-serine was 5-fold less than binding to membranes containing phosphatidyl-L-serine. Membranes containing synthetic phosphatidyl-L-homoserine, differing from phosphatidylserine by a single methylene, supported high-affinity binding, but it was not specific as factor VIII was displaced by other plasma proteins. O-Phospho-L-serine also inhibited the binding of factor VIII to platelet-derived microparticles with a Ki of 20 mM, and the stereoisomer was 4-fold less effective. These results indicate that membrane binding of factor VIII is mediated by a stereoselective recognition O-phospho-L-serine of phosphatidylserine and that negative electrostatic potential is of lesser importance.

    Essentials rVIII-SingleChain is a unique recombinant factor VIII (FVIII) molecule. A population pharmacokinetic model was based on FVIII activity of severe hemophilia A patients. The model was used to simulate factor VIII activity-time profiles for various dosing scenarios. The model supports prolonged dosing of rVIII-SingleChain with intervals of up to twice per week. Background Single-chain recombinant coagulation factor VIII (rVIII-SingleChain) is a unique recombinant coagulation factor VIII molecule. Objectives To: (i) characterize the population pharmacokinetics (PK) of rVIII-SingleChain in patients with severe hemophilia A; (ii) identify correlates of variability in rVIII-SingleChain PK; and (iii) simulate various dosing scenarios of rVIII-SingleChain. Patients/Methods A population PK model was developed, based on FVIII activity levels of 130 patients with severe hemophilia A (n = 91 for ≥ 12-65 years; n = 39 for  85% and > 93% of patients were predicted to maintain FVIII activity level above 1 IU dL -1 , at all times with three-times-weekly dosing (given on days 0, 2, and 4.5) at the lowest (20 IU kg -1 ) and highest (50 IU kg -1 ) doses, respectively. For twice weekly dosing (days 0 and 3.5) of 50 IU kg -1 rVIII-SingleChain, 62-80% of patients across all ages were predicted to maintain a FVIII activity level above 1 IU dL -1 at day 7. Conclusions The population PK model adequately characterized rVIII-SingleChain PK, and the model can be utilized to simulate FVIII activity-time profiles for various dosing scenarios. © 2017 The Authors.

    Mutations at the factor VIII gene locus causing Haemophilia A have now been identified in many patients from a many ethnic groups. Earlier studies used biased methods which detected repetitive mutations at a few CG dinucleotides. More recently rapid gene scanning methods have uncovered an extreme diversity of mutations. Over 80 different point mutations, 6 insertions, 7 small deletions, and 60 large deletions have been characterized. Repetitive mutation has been proved for at least 16 CpG sites. All nonsense mutations cause severe disease. Most missense mutations appear to cause instability of the protein, but some are associated with production of dysfunctional factor VIII molecules, thereby localizing functionally critical regions of the cofactor. Variable phenotype has been observed in association with three of the latter class of genotype. This catalogue of gene lesions in Haemophilia A will be updated annually.

    Full Text Available Flow cytometry is widely used in cancer research for diagnosis, detection of minimal residual disease, as well as immune monitoring and profiling following immunotherapy. Detection of specific host proteins for diagnosis predominantly uses quantitative PCR and western blotting assays. In this study, we optimized a flow cytometry-based detection assay for Factor VIII protein in peripheral blood mononuclear cells (PBMCs. An indirect intracellular staining (ICS method was standardized using monoclonal antibodies to different domains of human Factor VIII protein. The FVIII protein expression level was estimated by calculating the mean and median fluorescence intensities (MFI values for each monoclonal antibody. ICS staining of transiently transfected cell lines supported the method's specificity. Intracellular FVIII protein expression was also detected by the monoclonal antibodies used in the study in PBMCs of five blood donors. In summary, our data suggest that intracellular FVIII detection in PBMCs of hemophilia A patients can be a rapid and reliable method to detect intracellular FVIII levels.

    1994-09-01

    To develop a small animal model of hemophilia A for gene therapy experiments, we set out to construct a mouse model for factor VIII deficiency by gene targeting. First, we screened a mouse liver cDNA library using a human FVIII cDNA probe. We cloned a 2.6 Kb partial mouse factor VIII cDNA which extends from 800 base pairs of the 3{prime} end of exon 14 to the 5{prime} end of exon 26. A mouse genomic library made from strain 129 was then screened to obtain genomic fragments covering the exons desired for homologous recombination. Two genomic clones were obtained, and one covering exon 15 through 22 was used for gene targeting. To make gene targeting constructs, a 5.8 Kb genomic DNA fragment covering exons 15 to 19 of the mouse FVIII gene was subcloned, and the neo expression cassette was inserted into exons 16 and 17 separately by different strategies. These two constructs were named MFVIIIC-16 and MFVIIIC-17. The constructs were linearized and transfected into strain 129 mouse ES cells by electroporation. Factor VIII gene-knockout ES cell lines were selected by G-418 and screened by genomic Southern blots. Eight exon 16 targeted cell lines and five exon 17 targeted cell lines were obtained. Three cell lines from each construct were injected into blastocysts and surgically transferred into foster mothers. Multiple chimeric mice with 70-90% hair color derived from the ES-cell genotype were seen with both constructs. Germ line transmission of the ES-cell genotype has been obtained for the MFVIIIC-16 construct, and multiple hemophilia A carrier females have been identified. Factor VIII-deficient males will be conceived soon.

    In recent years the upper Rhone Valley has been one of the most intensively investigated regions by the Swiss Seismological Service. The high seismicity in the region encourages research in the seismological field and one main focus has been historical seismology. This report presents the state of the art of our historical investigations by giving an overview of the effects of four damaging earthquakes with intensity larger than VII, for which a fairly large number of documents could be found and analyzed. The overview includes the events of 1584 (Aigle, epicentral intensity VIII), 1755 (Brig, epicentral intensity VIII), 1855 (Visp, epicentral intensity VIII), and 1946 (Sierre, epicentral intensity VIII for the main shock and intensity VII for the largest aftershock). The paper focuses mainly on primary and secondary effects in the epicentral region, providing the key data and a general characterization of the event. Generally, primary effects such as the reaction of the population and impact on buildings took more focus in the past. Thus building damage is more frequently described in historic documents. However, we also found a number of sources describing secondary effects such as landslides, snow avalanches, and liquefaction. Since the sources may be useful, we include citations of these documents. The 1584 Aigle event, for example, produced exceptional movements in the Lake of Geneva, which can be explained by an expanded sub aquatic slide with resultant tsunami and seiche. The strongest of the aftershocks of the 1584 event triggered a destructive landslide covering the villages Corbeyrier and Yvorne, Vaud. All macroseismic data on the discussed events are accessible through the web page of the Swiss Seismological Service (http://www.seismo.ethz.ch). (authors)

    Processing by the proprotein convertase furin is believed to be critical for the biological activity of multiple proteins involved in hemostasis, including coagulation factor VIII (FVIII). This belief prompted the retention of the furin recognition motif (amino acids 1645–1648) in the design of B-domain–deleted FVIII (FVIII-BDD) products in current clinical use and in the drug development pipeline, as well as in experimental FVIII gene therapy strategies. Here, we report that processing by fu...

    2018-03-01

    We present a major update to ElecSus, a computer program and underlying model to calculate the electric susceptibility of an alkali-metal atomic vapour. Knowledge of the electric susceptibility of a medium is essential to predict its absorptive and dispersive properties. In this version we implement several changes which significantly extend the range of applications of ElecSus, the most important of which is support for non-axial magnetic fields (i.e. fields which are not aligned with the light propagation axis). Supporting this change requires a much more general approach to light propagation in the system, which we have now implemented. We exemplify many of these new applications by comparing ElecSus to experimental data. In addition, we have developed a graphical user interface front-end which makes the program much more accessible, and have improved on several other minor areas of the program structure.

    Aminoglycoside phosphotransferases represent a broad class of enzymes that promote bacterial resistance to aminoglycoside antibiotics via the phosphorylation of hydroxyl groups in the latter. Here we report the spatial structure of the 3′-aminoglycoside phosphotransferase of novel VIII class (AphVIII) solved by X-ray diffraction method with a resolution of 2.15 Å. Deep analysis of APHVIII structure and its comparison with known structures of aminoglycoside phosphotransferases of various types reveals that AphVIII has a typical two-domain fold and, however, possesses some unique characteristics that distinguish the enzyme from its known homologues. The most important difference is the presence of the activation loop with unique Ser146 residue. We demonstrate that in the apo-state of the enzyme the activation loop does not interact with other parts of the enzyme and seems to adopt catalytically competent state only after substrate binding. - Highlights: • 3D structure of the novel aminoglycoside phosphotransferase AphVIII was obtained. • AphVIII activation loop is clearly identified in the electron density. • AphVIII has some unique structural features in its substrate C-ring binding pocket.

    Hemophilia A (HA) has an X-linked pattern of inheritance and is the most common of the hemorrhagic disorders. HA is caused by a decreased or deficiency of the functional clotting factor VIII (FVIII) and effects 1 in 5000-10,000 male births. The common treatment for hemophilia is replacement therapy by plasma-derived or recombinant FVIII. Approximately 20-30% of people with a severe type of HA develop an inhibitor and this phenomenon is the main challenge in the management of these patients. Genetic factors and environmental determinants contribute to inhibitor development. Here, the roles of various genetic and environmental factors such as the type of FVIII concentrate used, the number of exposure days, and peak treatment time will be discussed in detail. It seems this information is helpful for hematologists. A literature review was done in January 2016 on PubMed and Scopus using the following keywords:' h(a)emophilia A & factor VIII inhibitor', 'h(a)emophilia A & factor VIII alloantibody', 'h(a)emophilia A & inhibitor'. There was no time limitation; however, there was an English language limitation placed on the articles selected. Expert commentary: Influential genetic and environmental factors in developing inhibitors have been discussed. Most of the risk factors are related to previously untreated patients with hemophili.

    Recently, acquired as well as genetic prothrombotic factors are associated with thrombotic events. These factors have also been related to conditions of uteroplacental insufficiency such as pre-eclampsia, HELLP syndrome and severe intrauterine growth restriction (IUGR). The aim of this study was to determine whether elevated factor VIII levels are associated with uteroplacental insufficiency, in particular pre-eclampsia, HELLP syndrome or pregnancy-induced hypertension and intrauterine growth retardation. Plasma samples of 75 women with a history of pregnancy complicated by pre-eclampsia, HELLP syndrome, pregnancy induced hypertension or intrauterine growth restriction were tested for factor VIII:C (FVIII:C) levels at a minimum of 10 weeks post-partum. Laboratory results were compared to factor VIII:C levels found in a healthy control group of 272 women. Mean factor VIII:C levels were similar at 123 IU/dl in both the patient group and the controls. In a logistic regression model, after adjusting for age and blood group, no effect of factor VIII:C levels on the risk of pregnancy complications was observed, with the exception of IUGR with (OR 2.9, CI 1.0-8.7) or without hypertension (OR 2.0, CI 0.7-6.4). If the elevated level of factor VIII would be the sole factor responsible for the increased risk observed, one would expect to find an effect of blood group on risk as well (blood group being an important determinant of FVIII:C). While no such effect could be shown a causal relationship between elevated levels of factor VIII and conditions of uteroplacental insufficiency such as pre-eclampsia, HELLP syndrome, pregnancy-induced hypertension and IUGR is not very likely.

    Factor VIII is a procofactor that plays a critical role in blood coagulation, and is missing or defective in hemophilia A. We determined the X-ray crystal structure of B domain-deleted human factor VIII. This protein is composed of five globular domains and contains one Ca{sup 2+} and two Cu{sup 2+} ions. The three homologous A domains form a triangular heterotrimer where the A1 and A3 domains serve as the base and interact with the C2 and C1 domains, respectively. The structurally homologous C1 and C2 domains reveal membrane binding features. Based on biochemical studies, a model of the factor IXa-factor VIIIa complex was constructed by in silico docking. Factor IXa wraps across the side of factor VIII, and an extended interface spans the factor VIII heavy and light chains. This model provides insight into the activation of factor VIII and the interaction of factor VIIIa with factor IXa on the membrane surface.

    Intron 22 is the largest intron of the factor VIII gene and contains a CpG island from which two additional transcripts originate. One of these transcripts corresponds to the F8A gene which have telomeric extragenic copies in the X chromosome. An inversion involving homologous recombination between the intragenic and the distal or proximal copies of the F8A gene has been recently described as a common cause of severe hemophilia A (HA). We analyzed intron 22 rearrangements in 195 HA patients (123 familial and 72 sporadic cases). According to factor VIII levels, our sample was classified as severe in 114 cases, moderate in 29 cases and mild in 52 cases. An intron 22 (F8A) probe was hybridized to Southern blots of BcII digested DNA obtained from peripheral blood. A clear pattern of altered bands identifies distal or proximal inversions. We detected an abnormal pattern identifying an inversion in 49 (25%) of the analyzed cases. 43% of severe HA patients (49 cases) showed an inversion. As expected, no inversion was found in the moderate and mild group of patients. We found a high proportion (78%) of the distal rearrangement. From 49 identified inversions, 33 were found in familial cases (27%), while the remaining 15 were detected in sporadic patients (22%) in support that this mutational event occurs with a similar frequency in familial or sporadic cases. In addition, we detected a significant tendency of distal inversion to occur more frequently in familial cases than in sporadic cases. Inhibitor development to factor VIII was documented in approximately 1/3 of the patients with inversion. The identification of such a frequent molecular event in severe hemophilia A patients has been applied in our families to carrier and prenatal diagnosis, to determine the origin of the mutation in the sporadic cases and to detect the presence of germinal mosaicism.

    Full Text Available The kingdom of Castile experienced a process of political and territorial consolidation between the death of Sancho III in 1158 and the Curia of Carrión de los Condes in 1188, leaving behind the troublesome minority of Alfonso VIII and the subordination to the kingdom of Leon, and thus becoming a dominant power within the peninsula, and one that achieved considerable success in the Reconquest. The following article is part of a biographical approach to Eleanor Plantagenet, queen consort of Alfonso VIII, and by means of a specifi c focus offers an analysis of the role played by the English queen in this process of political consolidation of Castile. As we approach the eighth centenary of her death, the life and work of this little-studied woman emerges as a testimony to the important diplomatic and cultural tasks assumed by queens in twelfth-century Europe.

    Desde la muerte de Sancho III en 1158 a la Curia de Carrión de los Condes en 1188, el reino castellano experimentó una consolidación política y territorial que dejó atrás la problemática minoría de Alfonso VIII y la subordinación al reino de León, que lo constituyó en un poder dominante dentro de la península y que logró un avance importante en la empresa reconquistadora. El presente trabajo es parte de un acercamiento biográfico a Leonor Plantagenet, consorte de Alfonso VIII, y que por medio de un enfoque particular ofrece un análisis de la incidencia que tuvo la reina inglesa en este proceso de afianzamiento político de Castilla. En las vísperas del octavo centenario de su muerte, la vida y obra de esta mujer hasta ahora poco estudiada, surge como un testimonio importante a la labor diplomática y cultural que asumían las reinas en la Europa del siglo XII.

    Grotrian diagrams are presented to provide graphical overviews for 1,247 spectral lines of highly ionized cobalt, Co VIII through Co XXVII. In the usual diagram display such as that by Bashkin and Stoner (North-Holland, Amsterdam, 1975), the density of transitions is often too high to allow each transition to be drawn separately. Here in our modified diagrams, the transitions are also represented by lines connecting the upper and lower energy levels, but the lower energy levels are extended and repeated for successive configurations as needed. As a sequence, dense packing is avoided and all lines in a multiplet can be accommodated. (author)

    In this paper the growth process and morphological evolution of ZnO nanostructures were investigated in a series of experiments using chemical bath deposition. The experimental results indicate that the morphological evolution depends on the reaction conditions, particularly on OH{sup -} to Zn{sup 2+} ratio (which directly affects the pH). For low VI/II ratios, quasi-spherical nanoparticles of an average diameter 30 nm are obtained, whereas for larger VI/II ratios, nanorods with an average diameter less than 100 nm are produced, which indicates that by systematically controlling the VI/II ratio, it is possible to produce different shapes and sizes of ZnO nanostructures. A possible mechanism for the nanostructural change of the as-synthesized ZnO from particle to rod was elucidated based on the relative densities of H{sup +} and OH{sup -} in the solution.

    2017-01-01

    Hemophilia A (coagulation factor VIII deficiency) is a debilitating genetic disorder that is primarily treated with intravenous replacement therapy. Despite a variety of factor VIII protein formulations available, the risk of developing anti-dug antibodies (“inhibitors”) remains. Overall, 20–30% of patients with severe disease develop inhibitors. Current clinical immune tolerance induction protocols to eliminate inhibitors are not effective in all patients, and there are no prophylactic protocols to prevent the immune response. New experimental therapies, such as gene and cell therapies, show promising results in pre-clinical studies in animal models of hemophilia. Examples include hepatic gene transfer with viral vectors, genetically engineered regulatory T cells (Treg), in vivo Treg induction using immune modulatory drugs, and maternal antigen transfer. Furthermore, an oral tolerance protocol is being developed based on transgenic lettuce plants, which suppressed inhibitor formation in hemophilic mice and dogs. Hopefully, some of these innovative approaches will reduce the risk of and/or more effectively eliminate inhibitor formation in future treatment of hemophilia A. PMID:29225598

  14. Purification and characterization of factor VIII 1,689-Cys: a nonfunctional cofactor occurring in a patient with severe hemophilia A.

    1989-06-01

    We have purified the factor VIII from a CRM+ Hemophilia A plasma (90 U/dL VIII:Ag but 0 U/dL VIII:C) and analyzed the protein before and after thrombin activation by Western blotting with monoclonal antibodies (MoAbs). Normal or patient citrated plasma was ultracentrifuged, cryo-ethanol-precipitated and chromatographed on Sepharose 6B. The void volume fractions were reduced and subjected to ion exchange chromatography yielding material of specific activity approximately 1,000 U/mg protein (VIII:C or VIII:Ag). Factor VIII purified in this way from normal plasma is fully activatable by thrombin with proteolytic fragmentation as previously described by F. Rotblat et al (Biochemistry 24: 4294, 1985). Factor VIII 1,689-Cys has the normal distribution of factor VIII light and heavy chains prior to thrombin activation. After exposure to thrombin the heavy chain polypeptides were fully proteolysed but the light chain was totally resistant to cleavage. This is consistent with the demonstration in the patient's leucocyte DNA of a C to T transition in codon 1,689 converting Arg to Cys at the light chain thrombin cleavage site as previously described by J. Gitschier et al (Blood 72:1022, 1988). Uncleaved light chain of Factor VIII 1,689-Cys is not released from von Willebrand factor (vWF) by thrombin, but this is not the sole cause of the functional defect since the protein purified free of vWF has no coagulant activity. We conclude that the functional defect in factor VIII 1,689-Cys is a consequence of failure to release the acidic peptide from the light chain upon thrombin activation.

  3. Analysis of factor VIII gene inversions in 164 unrelated hemophilia A families

    Energy Technology Data Exchange (ETDEWEB)

    Vnencak-Jones, L.; Phillips, J.A. III; Janco, R.L. [Vanderbilt Univ. School of Medicine, Nashville, TN (United States)] [and others

    1994-09-01

    Hemophilia A is an X-linked recessive disease with variable phenotype and both heterogeneous and wide spread mutations in the factor VIII (F8) gene. As a result, diagnostic carrier or prenatal testing often relies upon laborious DNA linkage analysis. Recently, inversion mutations resulting from an intrachromosomal recombination between DNA sequences in one of two A genes {approximately}500 kb upstream from the F8 gene and a homologous A gene in intron 22 of the F8 gene were identified and found in 45% of severe hemophiliacs. We have analyzed banked DNA collected since 1986 from affected males or obligate carrier females representing 164 unrelated hemophilia A families. The disease was sporadic in 37%, familial in 54% and in 10% of families incomplete information was given. A unique deletion was identified in 1/164, a normal pattern was observed in 110/164 (67%), and 53/164 (32%) families had inversion mutations with 43/53 (81%) involving the distal A gene (R3 pattern) and 10/53 (19%) involving the proximal A gene (R2 pattern). While 19% of all rearrangements were R2, in 35 families with severe disease (< 1% VIII:C activity) all 16 rearrangements seen were R3. In 18 families with the R3 pattern and known activities, 16 (89%) had levels < 1%, with the remaining 2 families having {le} 2.4% activity. Further, 18 referrals specifically noted the production of inhibitors and 8/18 (45%) had the R3 pattern. Our findings demonstrate that the R3 inversion mutation patterns is (1) only seen with VIII:C activity levels of {le} 2.4%, (2) seen in 46% of families with severe hemophilia, (3) seen in 45% of hemophiliacs known to have inhibitors, (4) not correlated with sporadic or familial disease and (5) not in disequilibrium with the Bcl I or Taq I intron 18 or ST14 polymorphisms. Finally, in families positive for an inversion mutation, direct testing offers a highly accurate and less expensive alternative to DNA linkage analysis.

  5. Factor VIII S373L: mutation at P1' site confers thrombin cleavage resistance, causing mild haemophilia A.

    A novel CRM+ mutation, factor VIII position 373 serine to leucine substitution (FVIII 373-Leu) was identified during a survey of Factor VIII (FVIII) mutations. We have purified the variant protein from the patient's plasma in order to allow further characterisation of the molecule. The CRM+ plasma contained 120% Factor VIII antigen (FVIII:Ag) and 6% Factor VIII coagulant activity (FVIII:C). After purification the mutant FVIII was subjected to thrombin proteolysis, and was thereby activated 5.6-fold compared with 7-fold for wild type molecule. Subsequently, spontaneous inactivation of the mutant was much slower than noted for wild type FVIII. Western blot analysis using monoclonal antibodies demonstrated that thrombin cleavage of FVIII 373-Leu at positions 740 and 1689 were normal but that cleavage at position 372 was completely absent. Crystallographic coordinates of the active site of thrombin complexed to fibrinopeptide A were used to explore possible mechanistic reasons for the failure of thrombin to cleave the mutant FVIII at position 372. Steric hindrance between the mutant side chain and the side chain of the P1 residue was apparent. We conclude that the functional defect of FVIII 373-Leu results from the inability of thrombin to cleave the mutant at position 372-373, and propose that this is due to steric hindrance by the side chain of leucine 373, preventing correct formation of the enzyme substrate complex.

  6. The new albumin-free recombinant factor VIII concentrates for treatment of hemophilia: do they represent an actual incremental improvement?

    Science.gov (United States)

    Josephson, Cassandra D; Abshire, Thomas

    2004-07-01

    The goal of eliminating the low levels of infectious disease risk from hemophilia treatment has resulted in the development of multiple generations of recombinant factor VIII (rFVIII) products. The ideal product should be devoid of human and animal proteins, which may transmit infectious agents. These products should also maintain molecular integrity, hemostatic efficacy, similar immunogenicity, and acceptable side effect profiles as compared to plasma-derived factor VIII. Currently available first-, second-, and third-generation rFVIII products include Recombinate; Kogenate FS/Helixate FS and ReFacto; and Advate, respectively. During the evolution of rFVIII products, either full-length or B-domain-deleted factor VIII were transfected into immortalized cell lines. The B-domain-deleted product, ReFacto, has resulted in an additional method to monitor factor VIII levels. The third-generation products offer the theoretical advantage of being produced without human and/or animal proteins. Upon initial introduction into the marketplace, the newer products have a higher cost. However, when analyzing historical trends, the prices of these products are almost equivalent to first-generation products within 3 years of licensure. Thus, the initial cost of the product may be a minimal issue in the medical decision process when selecting rFVIII replacement therapy.

  10. Chromosome VIII disomy influences the nonsense suppression efficiency and transition metal tolerance of the yeast Saccharomyces cerevisiae.

    The SUP35 gene of the yeast Saccharomyces cerevisiae encodes the translation termination factor eRF3. Mutations in this gene lead to the suppression of nonsense mutations and a number of other pleiotropic phenotypes, one of which is impaired chromosome segregation during cell division. Similar effects result from replacing the S. cerevisiae SUP35 gene with its orthologues. A number of genetic and epigenetic changes that occur in the sup35 background result in partial compensation for this suppressor effect. In this study we showed that in S. cerevisiae strains in which the SUP35 orthologue from the yeast Pichia methanolica replaces the S. cerevisiae SUP35 gene, chromosome VIII disomy results in decreased efficiency of nonsense suppression. This antisuppressor effect is not associated with decreased stop codon read-through. We identified SBP1, a gene that localizes to chromosome VIII, as a dosage-dependent antisuppressor that strongly contributes to the overall antisuppressor effect of chromosome VIII disomy. Disomy of chromosome VIII also leads to a change in the yeast strains' tolerance of a number of transition metal salts. Copyright © 2015 John Wiley & Sons, Ltd.

    Full Text Available El interés de las ciencias aplicadas al deporte en los espectadores y el espectáculo deportivo ha sido más bien escaso y en muchos casos sobrecentrado en la violencia. El objetivo de este trabajo es proponer una clasificación alternativa de los aficionados al fútbol a partir del tipo de contacto que tienen con el espectáculo y describir sus valores, motivaciones y compromiso. Mil setecientas diecinueve personas asistentes a partidos de fútbol organizados por la Liga de Fútbol Profesional contestaron cuestionarios sobre sus valores, motivaciones y relación con el fútbol. Los resultados muestranque los entusiastas son los aficionados más motivados y comprometidos con el fútbol al mismo tiempo que participan significativamente más de valores relacionados con el conservadurismo y la autopromoción que las otras tres categorías (espectadores, aficionados presenciales y aficionados virtuales. La clasificaciónpropuesta en base al tipo de contacto con el fútbol permite conceptualizar el fútbol como algo más que lo que ocurre en los estadios y abre las puertas a intervencionesdesde lo positivo para promover el fair play y la deportividad en los aficionados.

    Full Text Available Abstract: In Brazil, ever since colonization plants have been used as natural products; thus, the National Health Surveillance Agency has been establishing rules for herbal medicine regulation; in this light, 71 plant species were chosen and empirically used in the country to investigate their medicinal properties. Currently, 12 of these 71 plants have been approved to be used in SUS (Public Health System, the remaining species still need further research. Thusly, this review aimed to seek information from toxicological studies on the plants that have not yet been officially approved, to stimulate new research in the field, promoting an economical and functional impact. In order to obtain the information, the keywords plant name + toxicity and/or toxicological studies were searched in the most prominent databases, both in English and in Portuguese. The ten plants with the most references were included in this review. Among the ten plants assessed, three have all the required studies required by the National Health Surveillance Agency, two of which we recommend the immediate adoption by SUS. In general, three plants have a determined LD50, nine have reproductive toxicity data, and five have not yet shown any sign of toxicity.

    A new suite of evaluations for 54,56,57,58Fe has been developed in the framework of the CIELO international collaboration. New resolved resonance ranges were evaluated for 54Fe and 57Fe, while modifications were applied to resonances in 56Fe. The low energy part of the 56Fe file is almost totally based on measurements. At higher energies in 56Fe and in the whole fast neutron range for minor isotopes the evaluation consists of model predictions carefully adjusted to available experimental data. We also make use of the high quality and well experimentally-constrained dosimetry evaluations from the IRDFF library. Special attention was dedicated to the elastic angular distributions, which were found to affect results of the integral benchmarking. The new set of iron evaluations was developed in concert with other CIELO evaluations and they were tested together in the integral experiments before being adopted for the ENDF/B-VIII.0 library.

    This collection of papers is the result of a symposium sponsored by NATO's Defense Research Group Panel VIII in the Spring of 1985. The symposium came into being when it became obvious to the NATO countries that research, development and utilization of advanced technologies for training was the best means of increasing both training effectiveness and efficiency. This symposium was the second in a series of three devoted to training. The series was structured to cover all aspects of training. The first series addressed the value of training, the second one dealt with the application of training technologies and the third and last of the series focused on academic issues concerned with the effect of prior learning on subsequent learning. The fact that a major American publisher has determined that computer based instruction is the technology of greatest interest to the NATO community is not surprising. Advances in microprocessor technology have revolutionized both how and where we train. During this symposium t...

    The effect of recombinant factor VIII (rFVIII) brand on inhibitor development was investigated in all 407 severe hemophilia A previously untreated patients born in the United Kingdom (UK) between 1 January 2000 and 31 December 2011. Eighty-eight (22%) had been in the RODIN study. Information was extracted from the National Haemophilia Database. Because exposure days (EDs) were not known for some patients, time from first treatment was used as a surrogate for rFVIII exposure. An inhibitor developed in 118 (29%) patients, 60 high and 58 low titer, after a median (interquartile range) of 7.8 (3.3-13.5) months from first exposure and 16 (9-30) EDs. Of 128 patients treated with Kogenate Bayer/Helixate NexGen, 45 (35.2%, 95% confidence interval [CI] 27.4-43.8) developed an inhibitor compared with 42/172 (24.4%, 95% CI 18.6% to 31.4%) with Advate (P = .04). The adjusted hazard ratio (HR) (95% CI) for Kogenate Bayer/Helixate NexGen compared with Advate was 2.14 (1.12-4.10) (P = .02) for high titer and 1.75 (1.11-2.76) (P = .02) for all inhibitors. When excluding UK-RODIN patients, the adjusted HR (95% CI) for high-titer inhibitors was 2.00 (0.93-4.34) (P = .08). ReFacto AF was associated with a higher incidence of all, but not high-titer, inhibitors than Advate. These results will help inform debate around the relative immunogenicity and use of rFVIII brands. PMID:25339360

    Full Text Available Existe entre la Botánica y la Antropología una ciencia intermedia a la que, desde hace medio siglo, se ha dado el nombre de Etnobotánica. Como ocurre con otras ciencias interfacultativas o interdisciplinales la Etnobotánica no se puede definir fácilmente y por esto ha habido muchas diferencias de opinión en cuanto a su alcance y sus objetos. En su más amplio sentido, la Etnobotánica es el estudio de las relaciones que existen entre el hombre y su ambiente vegetal, es decir las plantas que lo rodean. En un sentido más restringido, se ha considerado solamente como el estudio del uso de las plantas cultivadas y silvestres por los pueblos primitivos, usualmente los aborígenes.

    Full Text Available The Greek philosophy developed three types of philosophical schools. The first one, represented by the Milesians, the Eleatics and partly the Aristotle’s Lyceum, understands the philosophical activity as a set of projects of investigation, not necessarily lacking of pragmatic interest, moved by desire to explain the phenomena. Next to their activities of investigation, many of these philosophers maintain a political activity within the framework of their own cities. The second type, represented by the Pythagoreans and the Academy of Plato, aims to reach the union between knowledge and political power. This proposal finds its better synthesis in the ideal of philosopher king. At the hellenistic period, the goal of philosophical schools would be to offer the cultivated and instructed man a particular way of life.La filosofía griega desarrolló tres tipos de escuelas filosóficas. El primero, representado por los milesios, los eleáticos y, en parte, el Liceo de Aristóteles, entiende la actividad filosófica como un conjunto de proyectos de investigación, no necesariamente carentes de interés pragmático, movidos por el deseo de explicar los fenómenos. Junto a sus actividades de investigación, muchos de estos filósofos mantienen una actividad política en el marco de las instituciones de sus propias ciudades. El segundo tipo, representado por los pitagóricos y la Academia platónica, se propone alcanzar la unión entre el saber y el poder. Esta propuesta halla su mejor síntesis en el ideal del filósofo rey. Finalmente, en la época helenística, las escuelas filosóficas se proponen sobre todo ofrecer un ideal de vida al hombre culto e instruido de su tiempo.

Este estudio tiene como objetivo identificar las creencias pedagógicas de treinta docentes de inglés de primaria, secundaria y terciaria, en Chile, sobre el rol estudiantil en el proceso didáctico. Un cuestionario, una entrevista semi-estructurada, un diario auto-biográfico y cinco diarios de observación no-participante fueron utilizados para revelar las creencias pedagógicas de sus informantes. Los datos arrojados por los instrumentos fueron analizados con el programa cualitativo ATLASTI, que permitió el levantamiento de tres dimensiones y diez categorías, mediante el uso de la técnica del análisis de contenido semántico. Los resultados muestran que los tres grupos de profesorado declaran que estudiantes que aprenden una lengua extranjera deben tener características personales y académicas relacionadas con la motivación, la participación, la autonomía, entre otras; sin embargo, al interior del aula asumen un rol pasivo y reactivo frente al ambiente de enseñanza altamente estructurado que genera el personal docente. En conclusión, las creencias que cada docente sostiene se alimentan de la teoría y se corroboran o cuestionan en la práctica de aula, a modo de una relación bidireccional entre teoría y práctica, y viceversa.

    Essentials von Willebrand factor (VWF) and factor VIII (FVIII) levels are modulated by age and ABO status. The effect of aging and ABO blood type on VWF and FVIII was assessed in 207 normal individuals. Aging and ABO blood type showed combined and bidirectional influences on VWF and FVIII levels. Aging and ABO blood type influence VWF levels through both secretion and clearance mechanisms. Background The effect of aging and ABO blood type on plasma levels of von Willebrand factor (VWF) and factor VIII (FVIII) have been widely reported; however, a comprehensive analysis of their combined effect has not been performed and the mechanisms responsible for the age-related changes have not been determined. Objectives To assess the influence of aging and ABO blood type on VWF and FVIII levels, and to evaluate the contribution of VWF secretion and clearance to the age-related changes. Methods A cross-sectional observational study was performed in a cohort of 207 normal individuals, whose levels of VWF, FVIII, VWF propeptide (VWFpp), VWFpp/VWF:Ag ratio and blood type A antigen content on VWF (A-VWF) were quantified. Results Aging and ABO blood type exerted interrelated effects on VWF and FVIII plasma levels, because the age-related increase in both proteins was significantly higher in type non-O individuals (β = 0.011 vs. 0.005). This increase with age in non-O subjects drove the differences between blood types in VWF levels, as the mean difference increased from 0.13 U/mL in the young to 0.57 U/mL in the old. Moreover, A-VWF was associated with both VWF antigen (β = 0.29; 95% confidence interval [CI], 0.09, 0.50) and VWF clearance (β = -0.15; 95% CI, -0.25, -0.06). We also documented an effect of ABO blood type on VWF secretion with aging, as old individuals with blood type non-O showed higher levels of VWFpp (mean difference 0.29 U/mL). Conclusions Aging and ABO blood type have an interrelated effect on VWF and FVIII levels, where the effect of one is significantly

Bleeding-related complications often result in greater severity of disease, poor quality of life, surgical interventions for severe joint destruction, and shortened life span. With the availability of plasma-derived and recombinant FVIII products, the benefits of primary prophylaxis were demonstrated and is now the standard of care for patients with severe factor deficiencies. Current hemophilia research is focusing on the creation of new factor replacement therapies with longer half-lives; accessing alternative mechanisms to achieve desired hemostasis and enhance bypassing ­activity; and limiting the immunogenicity of the protein. PEGylation involves the covalent attachment of polyethylene glycol (PEG to a protein, peptide, or a small molecule drug. PEG effectively increases the molecular weight and size of the protein by creating a hydrophilic cloud around the molecule. This molecular change may reduce susceptibility of the molecule to proteolytic activity and degradation. It is also believed that PEGylation changes the surface charge of the protein that ultimately interferes with some receptor-mediated clearance processes. The half-life of PEGylated factor is more prolonged when compared to non-PEGylated full-length recombinant FVIII. The dawn of a new era in the care of hemophilia patients is upon us with the release of recombinant FVIII products with extended half-lives, and products with even more extended half

    The vanadium(III) cation structure in mixed acid based electrolyte solution from vanadium redox flow batteries is studied by (17)O and (35/37)Cl nuclear magnetic resonance (NMR) spectroscopy, electronic spectroscopy and density functional theory (DFT) based computational modelling. Both computational and experimental results reveal that the V(III) species can complex with counter anions (sulfate/chlorine) depending on the composition of its solvation sphere. By analyzing the powder precipitate it was found that the formation of sulfate complexed V(III) species is the crucial process in the precipitation reaction. The precipitation occurs through nucleation of neutral species formed through deprotonation and ion-pair formation process. However, the powder precipitate shows a multiphase nature which warrants multiple reaction pathways for precipitation reaction.

    An immunoradiometric assay (IRMA) has been developed based on the inhibitor which arose in a polytransfused severe haemophiliac. The two-site IRMA measured antigens closely associated with the procoagulant parts of the factor VIII complex, which are termed FVIIIC antigens or FVIIICAG. FVIIICAG was present in normal plasma and also, at a slightly lower concentration, in normal serum. In 37 patients with haemophilia A, 36 had FVIIICAG levels of less than 10% of the normal plasma pool. In patients with von Willebrand's disease the levels of FVIIIC and FVIIICAG were in good agreement, both before and after treatment with cryoprecipitate or DDAVP. FVIIICAG was relatively stable in plasma at 37 0 C and could also be detected in cord and fetal serum. The assay is of potential value for detecting reduced levels of factor VIII, for carrier detection and for the prenatal diagnosis of haemophilia. (author)

    Recombinant VIII (rVIII)-SingleChain is a novel B-domain–truncated recombinant factor VIII (rFVIII), comprised of covalently bonded factor VIII (FVIII) heavy and light chains. It was designed to have a higher binding affinity for von Willebrand factor (VWF). This phase 1/3 study investigated the efficacy and safety of rVIII-SingleChain in the treatment of bleeding episodes, routine prophylaxis, and surgical prophylaxis. Participants were ≥12 years of age, with severe hemophilia A (endogenous FVIII <1%). The participants were allocated by the investigator to receive rVIII-SingleChain in either an on-demand or prophylaxis regimen. Of the 175 patients meeting study eligibility criteria, 173 were treated with rVIII-SingleChain, prophylactically (N = 146) or on-demand (N = 27). The total cumulative exposure was 14 306 exposure days (EDs), with 120 participants reaching ≥50 EDs and 52 participants having ≥100 EDs. Hemostatic efficacy was rated by the investigator as excellent or good in 93.8% of the 835 bleeds treated and assessed. Across all prophylaxis regimens, the median annualized spontaneous bleeding rate was 0.00 (Q1, Q3: 0.0, 2.4) and the median overall annualized bleeding rate (ABR) was 1.14 (Q1, Q3: 0.0, 4.2). Surgical hemostasis was rated as excellent/good in 100% of major surgeries by the investigator. No participant developed FVIII inhibitors. In conclusion, rVIII-SingleChain is a novel rFVIII molecule showing excellent hemostatic efficacy in surgery and in the control of bleeding events, low ABR in patients on prophylaxis, and a favorable safety profile in this large clinical study. This trial was registered at www.clinicaltrials.gov as #NCT01486927. PMID:27330001

    Full Text Available Introduction: The vascular compression by redundant vessels under the VIII cranial nerves has been studied since the 80's, and many authors proposed correlations between the compression and the otoneurological findings (vertigo, tinnitus, hypoacusis, audiometry and electrophysiological findings. Objective: Analyze and correlate the different signs and otoneurological symptoms, the audiological findings and its incidence over individuals with Vascular Loop (VL diagnosis of VIII cranial nerves by magnetic resonance imaging (MRI. Method: Retrospective study through the analysis of medical records of 47 patients attended in the otoneurology clinic of Clinical Hospital of UFPR. All the patients have MRI exams with compatible pictures of VL of the VIII cranial nerves. Results: The tinnitus was the most frequent symptom, in 83% of the patients, followed by hypoacusis (60% and vertigo (36%. The audiometry presented alterations in 89%, the brainstem evoked auditory potential in 33% and the vecto-electronystagmography in 17% of the patients. Was not found statistically significant relation between the buzz or hypoacusis, and the presence of VL in MRI. Only 36% of patients had complaints of vertigo, the main symptom described in theory of vascular compression of the VIII pair of nerve. As in the audiometry and in brainstem evoked auditory potential was not found a statistically significant relation between the exam and the presence of the VL in the RMI. Conclusion: The results show independence between the findings of the RMI, clinical picture and audiological results (p>0,05 suggesting that there are no exclusive and direct relation between the diagnosis of vascular loop in the MRI and the clinical picture matching.

    Antigenic reactivity of F.VIII/WF in variants of von Willebrand's disease (vWd) was studied with both fluid-phase and solid-phase immunoradiometric assays. Two different (rabbit and goat) 125 I-labeled specific antibodies against purified F.VIII/WF were used in both their divalent (lgG) and their monovalent (Fab fragment) forms. Dose-response curves obtained by reacting a constant amount of antibody with serial dilutions of plasmas from normal or homozygous vWd demonstrated the specificity of the test. The accuracy was significantly higher with 125 I-Fab fragments of goat anti-F.VIII/WF antiserum than intact goat lgG or rabbit lgG or Fab fragments. The significant decrease of the slope of the dose-response curves obtained with plasma from variants of vWd has been interpreted as due to the presence of abnormal F.VIII/WF molecules with decreased antigenic reactivity. A similar anomaly was found in cryosupernatant prepared from normal plasma, paralleling similarities demonstrated between variants of vWd and cryosupernatant. Results of experiments performed by reacting constant plasma dilutions from control or variants of vWd and varying concentrations of anti-F.VIII/WF Fab fragments (rabbit or goat) confirmed the decreased antigenic reactivity of variant F.VIII/WF

    Microstructural damage and nano hardness of the industrial grade stainless steel (SUS-316) have been studied under proton (H + ) implanted condition applying different doses at room temperature. The implantation scheme such as proton energy, fluence, irradiation time, and penetration depth in the target materials were estimated by Monte Carlo Simulation Code SRIM-2008. In the simulation, the parameters were chosen in such a way that the damage density (displacement per atom or dpa) would be uniform up to certain depth from the surface. X-ray diffraction study of the annealed samples prior to the proton implantation showed the austenitic fcc structure and no significant change was observed after proton implantation in it. Microstructural observation made by Scanning Transmission Electron Microscopy (STEM) revealed that 1 dpa of proton-irradiation induced the structural damage extended up to 1 μm depth from the surface. The nano hardness study showed that the hardness level of the irradiated samples increased monotonically with the irradiation doses. Proton dose of 1 dpa caused 65% increment of hardness level on average in case of uniformly irradiated samples. It was realized that the increment of hardness was a consequence of microstructural damages caused by the formation of interstitial dislocation loops in the sample matrix keeping the lattice structure unaffected

    PNC provided SUS 304 plate to be irradiated in FFTF at about 400 0 C to a target fluence of 5 x 10 21 n/cm 2 (E > 0.1 MeV). The actual irradiation included two basically different exposure levels to assure that information would be available for the exposure of interest. After irradiation, tensile properties, fatigue-crack growth rates and J-integral fracture toughness response were determined. These same properties were also measured for the unirradiated material so radiation damage effects could be characterized. This report presents the results of this program. It is expected that these results would be applicable for detailed fracture analysis of reactor components. Recent advances in elastic-plastic fracture mechanics enable reasonably accurate predictions of failure conditions for flawed stainless steel components. Extensive research has focused on the development of J-integral-based engineering approach for assessing the load carrying capacity of low-strength, high-toughness structural materials. Furthermore, Kanninen, et al., have demonstrated that J-integral concepts can accurately predict the fracture response for full-scale cracked structures manufactured from Type 304 stainless steel

Se formularon matrices con registros biológicos y socioeconómicos obtenidos entre el 2009 y 2010 en temporadas de alto registro turístico, obteniendo 17 variables en 20 playas analizadas. La evaluación se efectuó con el modelo semiparamétrico del tipo KSIM con dos escenarios: uno sin control/restricción en el desarrollo costero y otro con las mismas características pero con decremento en demanda turística por baja calidad ambiental. Los resultados mostraron un marcado descenso en playas arenosas y costas rocosas. En el modelo se hace referencia a la importancia de los procesos de las playas y su interrelación con los factores biológicos, sociales y económicos más importantes, proporcionando una visión integral de todas las variables. Se recomienda incrementar el modelo dándole mayor envergadura, integrando a las instituciones que influyen en el control de las acciones en estas playas, lo que dará un mejor referente y monitoreo a corto, mediano y largo plazo.

  10. Partial correction of a severe molecular defect in hemophilia A, because of errors during expression of the factor VIII gene

    Although the molecular defect in patients in a Japanese family with mild to moderately severe hemophilia A was a deletion of a single nucleotide T within an A{sub 8}TA{sub 2} sequence of exon 14 of the factor VIII gene, the severity of the clinical phenotype did not correspond to that expected of a frameshift mutation. A small amount of functional factor VIII protein was detected in the patient`s plasma. Analysis of DNA and RNA molecules from normal and affected individuals and in vitro transcription/translation suggested a partial correction of the molecular defect, because of the following: (i) DNA replication/RNA transcription errors resulting in restoration of the reading frame and/or (ii) {open_quotes}ribosomal frameshifting{close_quotes} resulting in the production of normal factor VIII polypeptide and, thus, in a milder than expected hemophilia A. All of these mechanisms probably were promoted by the longer run of adenines, A{sub 10} instead of A{sub 8}TA{sub 2}, after the delT. Errors in the complex steps of gene expression therefore may partially correct a severe frameshift defect and ameliorate an expected severe phenotype. 36 refs., 6 figs.

São ponderadas algumas teses na Saúde Coletiva à luz de estudos mais recentes nas Ciências Sociais sobre o sindicalismo e realizada análise documental para o caso da Central Única dos Trabalhadores (CUT, tomado aqui como referência. Aponta-se a necessidade de considerar os pesos relativos que a ação sindical atribuiu a cada um dos aspectos da relação, SUS e planos privados de saúde, pelas distintas conjunturas do país. O conflito entre trabalhadores e empresas somado ao desemprego e à precarização do trabalho expõe os limites das coberturas assistenciais privadas e impele a representação sindical a pleitear a intervenção estatal. O trabalho refletiu sobre as distintas modalidades de ação sindical na empresa e no Estado. A complexidade dessa dinâmica fez emergir um setor sindical interessado na gestão da previdência complementar e dos planos de saúde e, ao mesmo tempo, recria as circunstâncias e traz novas possibilidades de as organizações sindicais se colocarem na cena política e aglutinar os interesses de amplos segmentos dos trabalhadores para pressionar o Estado na defesa da melhoria do sistema público de saúde.The article intends to discuss the patterns of interlocution between the Brazilian trade unionism, the public health system (SUS and the private health insurance sector.

    Recombinant factor VIII Fc fusion protein (rFVIIIFc) is a long-acting coagulation factor approved for the treatment of hemophilia A. Here, the rFVIIIFc manufacturing process and results of studies evaluating product quality and the capacity of the process to remove potential impurities and viruses are described. This manufacturing process utilized readily transferable and scalable unit operations and employed multi-step purification and viral clearance processing, including a novel affinity chromatography adsorbent and a 15 nm pore size virus removal nanofilter. A cell line derived from human embryonic kidney (HEK) 293H cells was used to produce rFVIIIFc. Validation studies evaluated identity, purity, activity, and safety. Process-related impurity clearance and viral clearance spiking studies demonstrate robust and reproducible removal of impurities and viruses, with total viral clearance >8-15 log10 for four model viruses (xenotropic murine leukemia virus, mice minute virus, reovirus type 3, and suid herpes virus 1). Terminal galactose-α-1,3-galactose and N-glycolylneuraminic acid, two non-human glycans, were undetectable in rFVIIIFc. Biochemical and in vitro biological analyses confirmed the purity, activity, and consistency of rFVIIIFc. In conclusion, this manufacturing process produces a highly pure product free of viruses, impurities, and non-human glycan structures, with scale capabilities to ensure a consistent and adequate supply of rFVIIIFc.

    Energy levels and Grotrian diagrams of Fe(VIII) to Fe(XXVI) are presented. This report summarized the data published recently up to 1976, and the wavelength tables compiled were converted to the Grotrian diagrams. The diagrams showing transition from one energy level to another are called Grotrian diagrams. Typical examples of the diagrams are found in the book by Bashkin et al. In the present diagrams, all lines are drawn in parallel, and connected to the extended lines from lower levels. As the results, locally dense packing of lines and figures is avoided. The ordinate of the diagrams indicates level energy, and the J values are shown on the left side of the levels. The wavelength values in angstrom unit are written in parallel with the vertical transition lines. This vertical lines show the resonance transition having absorption oscillator strength f larger than 0.1. The present diagrams are the combination of the tables of wavelength and energy level. Accordingly, the desired wavelength and level energy are easily found. The figures of wavelength are lined up in various groups, so that the characteristics of the transition can be discriminated at a glance. Wavelength and level energy have been mostly derived from experimental spectra in laboratory or solar plasma, except a few by Fawcett's prediction. (Kato, T.)

  15. Synthesis of methyl acetate from dimethyl ether using group VIII metal salts of phosphotungstic acid

    2002-04-01

    Dimethyl ether (DME) can be produced much more efficiently in a single-stage, liquid-phase process from natural gas-based syngas as compared to the conventional process via dehydration of methanol. This process, based on dual catalysts slurried in inert oil, alleviates the chemical equilibrium limitation governing the methanol synthesis reaction and concurrently improves per-pass syngas conversion and reactor productivity. The potential, therefore, for production of methyl acetate via dimethyl ether carbonylation is of industrial importance. In the present study, conversion of dimethyl ether and carbon monoxide to methyl acetate is investigated over a variety of group VIII metal-substituted phosphotungstic acid salts. Experimental results of this catalytic reaction using rhodium, iridium, ruthenium, and palladium catalysts are evaluated and compared in terms of selectivity toward methyl acetate. The effects of active metal, support types, multiple metal loading, and feed conditions on carbonylation activity of DME are examined. Iridium metal substituted phosphotungstic acid supported on Davisil type 643 (pore size 150 A, surface area 279 m{sup 2}/g, mesh size 230-425) silica gel shows the highest activity for DME carbonylation.

    Tungsten spectra excited in the vacuum sparks of different setups and electric circuits were recorded on two high-resolution vacuum spectrographs. For the region 190–500 Å, a 10 m normal incidence spectrograph with a 3600 lines/mm grating was used in the Meudon Observatory. In the region below 350 Å, a set of spectra was produced using a 3 m grazing incidence spectrograph with a 3600 lines/mm grating in the Institute of Spectroscopy in Troitsk. A total of 187 lines in the region 160–271 Å were identified as transitions to the low-lying odd configurations 4f 13 5s 2 5p 6 and 4f 14 5s 2 5p 5 from the interacting excited even 4f 12 5s 2 5p 6 5d + 4f 13 5s 2 5p 5 (5d + 6s) + 4f 14 5s 2 5p 4 (5d + 6s) + 4f 14 5s5p 6 configurations. It was found that 4f 13 5s 2 5p 6 2 F 7/2 is the ground level of W VIII. The fine structure splitting and relative positions of the odd terms were established, and 98 levels of the excited even configurations were found. (paper)

    The occurrence of anti-factor VIII (FVIII) allo-antibodies is a severe complication of the treatment of haemophilia A patients, leading to the inhibition of transfused FVIII activity. The effective elimination of these inhibitory antibodies plays a decisive role in the management of affected patients. To achieve this, immunoadsorption devices employing synthetic adsorbers, which selectively eliminate inhibitors, are of interest in the treatment strategy of haemophilia A patients with inhibitors. Adsorbers consisting of polystyrene-based beads substituted with sulphonate and L-tyrosyl methylester groups, which mimic part of epitope of FVIII molecule recognized by inhibitors, exhibit selective binding capacities towards anti-FVIII antibodies. The adsorption of FVIII inhibitors was investigated by simulating an extracorporeal circulation of haemophilic plasma over these functionalized resins. These innovative adsorbers are able to remove around 25% of anti-FVIII antibodies in 15 minutes depending on the plasma tested. Furthermore, they do not modify the amount of essential plasmatic proteins or residual immunoglobulins G. Experiments which were carried out using different plasmas with various inhibitor titres demonstrate a good reproducibility regarding the adsorption capacity of the synthetic resin. The characteristics of adsorption are similar on either native or regenerated resins. Both the purely synthetic nature of the resin and its easy processability demonstrate the real advantages over currently available protocols. This synthetic adsorber is a major technological advance in selective removal of FVIII inhibitory antibodies.

    Human clotting factor VIII (hFVIII) is a very complex and large protein whose expression is difficult, as hFVIII requires extensive post-translational modification to be biologically active. This paper reports the generation of transgenic rabbits as a model species for testing the expression of hFVIII in the mammary gland. For micro-injection, a fusion gene construct was used, consisting of 2.5 kb murine whey acidic protein (mWAP) promoter, 7.2 kb cDNA of hFVIII, and 4.6 kb of 3' flanking sequences of the mWAP gene. from 130 micro-injected zygotes transferred into recipients, 30 offspring were delivered. The pups were screened for the transgene by PCR, using DNA isolated from the ear, and results were confirmed by Southern blot analysis. The transgene was identified in one female founder animal, and it was transmitted to the offspring in a Mendelian fashion, thus demonstrating stable integration of the gene construct into the germline of the transgenic rabbits.

    Nattokinase, a serine proteinase from Bacillus subtilis, is considered to be one of the most active functional ingredients found in natto. In this study, we hypothesized that nattokinase could reduce certain factors of blood clotting and lipids that are associated with an increase risk for cardiovascular disease (CVD). Thus, an open-label, self-controlled clinical trial was conducted on subjects of the following groups: healthy volunteers (Healthy Group), patients with cardiovascular risk factors (Cardiovascular Group), and patients undergoing dialysis (Dialysis Group). All subjects ingested 2 capsules of nattokinase (2000 fibrinolysis units per capsule) daily orally for 2 months. The laboratory measurements were performed on the screening visit and, subsequently, regularly after the initiation of the study. The intent-to-treat analysis was performed on all 45 enrolled subjects. By use of mixed model analysis, a significant time effect, but not group effect, was observed in the change from baseline of fibrinogen (P = .003), factor VII (P nattokinase. No significant changes of uric acid or notable adverse events were observed in any of the subjects. In summary, this study showed that oral administration of nattokinase could be considered as a CVD nutraceutical by decreasing plasma levels of fibrinogen, factor VII, and factor VIII.

    Processing by the proprotein convertase furin is believed to be critical for the biological activity of multiple proteins involved in hemostasis, including coagulation factor VIII (FVIII). This belief prompted the retention of the furin recognition motif (amino acids 1645–1648) in the design of B-domain–deleted FVIII (FVIII-BDD) products in current clinical use and in the drug development pipeline, as well as in experimental FVIII gene therapy strategies. Here, we report that processing by furin is in fact deleterious to FVIII-BDD secretion and procoagulant activity. Inhibition of furin increases the secretion and decreases the intracellular retention of FVIII-BDD protein in mammalian cells. Our new variant (FVIII-ΔF), in which this recognition motif is removed, efficiently circumvents furin. FVIII-ΔF demonstrates increased recombinant protein yields, enhanced clotting activity, and higher circulating FVIII levels after adeno-associated viral vector–based liver gene therapy in a murine model of severe hemophilia A (HA) compared with FVIII-BDD. Moreover, we observed an amelioration of the bleeding phenotype in severe HA dogs with sustained therapeutic FVIII levels after FVIII-ΔF gene therapy at a lower vector dose than previously employed in this model. The immunogenicity of FVIII-ΔF did not differ from that of FVIII-BDD as a protein or a gene therapeutic. Thus, contrary to previous suppositions, FVIII variants that can avoid furin processing are likely to have enhanced translational potential for HA therapy. PMID:27734034

    The spectrum of tellurium was photographed in the 100-500 A region on a variety of grazing incidence spectrographs using a triggered spark source. The analysis of the lines in the 117-216 A region has lead to establishing 42 out of 45 levels of the 4d 8 6p configuration of Te VIII. Four levels of the 4d 8 4f configuration were confirmed and their level values revised, and an additional 4d 8 4f level was established. The 4p 5 4d 10 levels reported earlier were found to be erroneous and new values have been found for them. Eighty seven (87) new lines have been classified in the (4d 9 + 4d 8 5s)-(4d 8 4f + 4p 5 4d 10 + 4d 8 6p) transition array. Hartree-Fock with relativistic corrections (HFR) and parametric least-squares-fitted (lSF) calculations were carried out to interpret the present analysis adequately. (orig.)

    Activity of factor VIII (FVIII) increased above 150% of reference range predisposes to venous thromboembolism (VTE). The aim of this study was to identify predictors of increased FVIII activity in patients following VTE. 241 (38% men) patients presented due to objectively documented VTE episode at least 3 months ago were included in this study. FVIII activity was measured using a clotting assay on the analyzer BCS XP. Among 241 patients with VTE, activity of FVIII above 150% (FVIII ≥ 150%) was observed in 96 (40%). These patients were older (p = 0.035) and their concentrations of fibrinogen and C-reactive protein (CRP) were higher by 12% and 88% (p 200%) and this group was also older (p = 0.015), more patients in that group had obesity (p = 0.015), idiopathic VTE (p = 0.043), less of them had positive family history (p = 0.010) and they were characterized by fibrinogen and CRP increased by 28% (p 200% (p = 0.016). The activity of FVIII in patients after VTE episode is influenced by age, concentration of fibrinogen, bilirubin, hemoglobin, glucose, CRP and homocysteine. Our results suggest the role of environmental factors, mainly inflammatory response in maintaining elevated FVIII activity following VTE.

    Full Text Available El presente artículo analiza la crisis estructural del capitalismo provocada por el estallido de la burbuja especulativa inmobiliaria en EEUU en 2007 y sus repercusiones. El presente fenómeno es el desenlace de una serie de procesos desencadenados en respuesta a la crisis de sobreacumulación del capital de los años setenta que generó, por un lado, las condiciones para el dominio del capital financiero y, por otro lado, una nueva frontera de acumulación del capital en el Este asiático, sobre todo en China. La crisis cuestiona la centralidad de la economía norteamericana, lo que no significa necesariamente el desplazamiento del centro hegemónico del capitalismo hacia Asia. Lo que aquí defendemos, es la idea de que nos dirigimos hacia un mundo multipolar. This article analyzes the structural crisis of capitalism that began when the speculative home mortgage bubble burst in the United States in 2007, and the repercussions of that phenomenon. The current crisis is the outcome of a series of processes unleashed as a result of the crisis of overaccumulation of capital in the 1970s, which generated, on the one hand, the conditions for financial capital’s dominance and, on the other, a new frontier for the accumulation of capital in East Asia, especially in China. The crisis calls into question the centrality of the North American economy, but that does not necessarily mean the shift of capitalism’s hegemonic center to Asia. Here we will argue that we are headed toward a multipolar world.

    Essentials rVIII-SingleChain is a novel recombinant factor VIII with covalently bonded heavy and light chains. Efficacy, safety and pharmacokinetics were studied in pediatric patients with severe hemophilia A. Across all prophylaxis regimens, the median annualized spontaneous bleeding rate was 0.00. rVIII-SingleChain showed excellent hemostatic efficacy and a favorable safety profile. Background rVIII-SingleChain is a novel B-domain truncated recombinant factor VIII (rFVIII) comprised of covalently bonded FVIII heavy and light chains, demonstrating a high binding affinity to von Willebrand factor. Objectives This phase III study investigated the safety, efficacy and pharmacokinetics of rVIII-SingleChain in previously treated pediatric patients hemophilia A. Patients/Methods Patients could be assigned to prophylaxis or on-demand therapy by the investigator. For patients assigned to prophylaxis, the treatment regimen and dose were based on the bleeding phenotype. For patients receiving on-demand therapy, dosing was guided by World Federation of Hemophilia recommendations. The primary endpoint was treatment success, defined as a rating of 'excellent' or 'good' on the investigator's clinical assessment of hemostatic efficacy for all treated bleeding events. Results The study enrolled 84 patients (0 to 50 EDs. In the 347 bleeds treated and evaluated by the investigator, hemostatic efficacy was rated as excellent or good in 96.3%. The median annualized spontaneous bleeding rate was 0.00 (Q1, Q3: 0.00, 2.20), and the median annualized bleeding rate was 3.69 (Q1, Q3: 0.00, 7.20) across all prophylaxis regimens. No participant developed an inhibitor.

    Animals with hemophilia are models for gene therapy, factor replacement, and inhibitor development in humans. We have actively sought dogs with severe hemophilia A that have novel factor VIII mutations unlike the previously described factor VIII intron 22 inversion. A male Old English Sheepdog with recurrent soft-tissue hemorrhage and hemarthrosis was diagnosed with severe hemophilia A (factor VIII activity less than 1% of normal). We purified genomic DNA from this dog and ruled out the common intron 22 inversion; we then sequenced all 26 exons. Comparing the results with the normal canine factor VIII sequence revealed a C→T transition in exon 12 of the factor VIII gene that created a premature stop codon at amino acid 577 in the A2 domain of the protein. In addition, 2 previously described polymorphisms that do not cause hemophilia were present at amino acids 909 and 1184. The hemophilia mutation creates a new TaqI site that facilitates rapid genotyping of affected offspring by PCR and restriction endonuclease analyses. This mutation is analogous to the previously described human factor VIII mutation at Arg583, which likewise is a CpG dinucleotide transition causing a premature stop codon in exon 12. Thus far, despite extensive treatment with factor VIII, this dog has not developed neutralizing antibodies (‘inhibitors’) to the protein. This novel mutation in a dog gives rise to severe hemophilia A analogous to a mutation seen in humans. This model will be useful for studies of the treatment of hemophilia. PMID:27780008

    The development of anti-factor VIII (FVIII) neutralizing antibodies (inhibitors) is the major complication in hemophilia A. Nonneutralizing antibodies (NNAs) have been detected in hemophilia patients and also in unaffected individuals. The aim of this study was to assess the prevalence of NNAs and to evaluate whether their presence is associated with the development of inhibitors in a cohort of previously untreated or minimally treated patients with hemophilia A; plasma samples of 237 patients with severe hemophilia A enrolled in the SIPPET trial were collected before any exposure to FVIII concentrates and analyzed for the presence of anti-FVIII NNAs. Patients were observed for the development of neutralizing antibodies. NNAs were found in 18 (7.6%) of 237 patients at screening, and there was a clear age gradient. Of those with NNAs, 7 patients subsequently developed an inhibitor for a cumulative incidence of 45.4% (95% confidence interval [CI], 19.5% to 71.3%); among the 219 patients without NNAs, 64 (29%) developed an inhibitor (cumulative incidence, 34.0%; 95% CI, 27.1%-40.9%). In Cox regression analyses, patients with NNAs at screening had an 83% higher incidence of inhibitor development than patients without NNAs (hazard ratio [HR], 1.83; 95% CI, 0.84-3.99). For high-titer inhibitors, the incidence rate had an almost threefold increase (HR, 2.74; 95% CI, 1.23-6.12). These associations did not materially change after adjustment. The presence of anti-FVIII NNAs in patients with severe hemophilia A who were not previously exposed to FVIII concentrates is associated with an increased incidence of inhibitors. © 2017 by The American Society of Hematology.

    The allelic frequency of any polymorphism within a population determines its usefulness for genetic counselling. This is important in populations of non-Caucasian origin as RFLPs may significantly differ among ethnic groups. We report a study of five intragenic polymorphisms in factor VIII gene carried out in Singapore. The three PCR-based RFLP markers studied were Intron 18/Bcl I, Intron 19/Hind III and Intron 22/Xba I. In an analysis of 148 unrelated normal X chromosomes, the allele frequencies were found to be A1 = 0.18, A2 = 0.82 (Bcl I RFLP), A1 = 0.80, A2 = 0.20 (Hind III RFLP) and A1 = 0.58, and A2 = 0.42 (Xba I RFLP). The heterozygosity rates of 74 females analyzed separately were 31%, 32% and 84.2%, respectively. Linkage disequilibrium was also observed to some degree between Bcl I and Hind III polymorphism in our population. We have also analyzed a sequence polymorphism in Intron 7 using hybridization with radioactive-labelled {sup 32}P allele-specific oligonucleotide probes. This polymorphism was not very polymorphic in our population with only 2% of 117 individuals analyzed being informative. However, the use of a hypervariable dinucleotide repeat sequence (VNTR) in Intron 13 showed that 25 of our of 27 (93%) females were heterozygous. Allele frequencies ranged from 1 to 55 %. We conclude that a viable strategy for molecular analysis of Hemophilia A families in our population should include the use of Intron 18/Bcl I and Intron 22/Xba I RFLP markers and the Intron 13 VNTR marker.

O melhor entendimento das técnicas de biologia molecular com citofotometria de imagem, permitiu avançar no conhecimento das alterações na expressão das proteínas desse câncer. OBJETIVOS: Quantificar a expressão das proteínas envolvidas na angiogênese e correlacioná-las com variáveis clínico-patológicas. MÉTODOS: Com o uso da técnica de imunoistoquímica, citofotometria de imagem pelo sistema SAMBA, foram analisadas 29 amostras de carcinoma epidermóide do esôfago incluídas em blocos de parafina. Critérios clínicos como idade, sexo e histopatológicos do grau de diferenciação tumoral, tamanho e localização do tumor foram analisados. Os parâmetros analisados foram o índice de marcagem e a densidade óptica. O marcador utilizado foi o anticorpo anti-Fator VIII. RESULTADOS: Foi possível verificar que as expressões médias do marcador no índice de marcagem foram maiores que as da densidade óptica. Fator VIII apresentou leituras homogêneas. O índice de marcagem foi de 80,17+/-10,40 com P=0,073 e a densidade óptica 51,25+/-11,02 com P=0,245. CONCLUSÃO: A análise quantificação da expressão das proteínas envolvidas na angiogênese permite definir subgrupos de acordo com a diferenciação do carcinoma, estágio tumoral, tamanho e localização do tumor, porém não associa-se com o sexo e a idade dos pacientes, e a densidade óptica do Fator VIII não tem expressão significativa em nenhum dos subgrupos analisados.BACKGROUND: Squamous cell carcinoma of the esophagus exhibits high mortality rate, rare precocious diagnosis, and expensive treatments, presenting frequently disappointed results and poor prognosis.

    In this study we examined the staining reactivity of commercially available antisera to factor VIII related antigen (F VIII RAg) and Ulex europaeus agglutinin I (UEA-I) on sections from 230 formalin fixed paraffin embedded tumours. These included 196 sarcomas, 20 carcinomas and 14 angiomas. All angiomas showed positive staining for F VIII RAg; all carcinomas showed negative staining; the vasoformative areas of all angiosarcomas stained positively but only four of six angiosarcomas showed positive staining of their solid areas; of seven Kaposi's sarcomas, all showed positive staining of vessels and six showed positive staining of the spindle cell component. In the remaining 181 non-vascular sarcomas there was a false positive result in four tumours (2.2%), three of which had a history of irradiation. Pre-radiotherapy biopsies of these three tumours stained negatively with anti-F VIII RAg. UEA-I was demonstrated in all the angiomas studied, in all angiosarcomas (including the solid components) and in well-formed vessels of all Kaposi's sarcomas, but only in the spindle cell component of 3/6. However, there was an unacceptably high rate of false positive staining amongst the carcinomas and non-vascular sarcomas. In conclusion, F VIII RAg is a specific but not a sensitive marker of angiosarcomas; UEA-I is a sensitive but not a specific marker of angiosarcomas.

    Full Text Available Epitaxial Alx Ga1-x Sb layers on GaSb and GaAs substrates have been grown by atmospheric pressure metalorganic chemical vapor deposition using TMAl, TMGa and TMSb. Nomarski microscope and a profiler were employed to examine the surface morphology and growth rate of the samples. We report the effect of growth temperature and V/III flux ratio on growth rate and surface morphology. Growth temperatures in the range of 520°C and 680°C and V/III ratios from 1 to 5 have been investigated. A growth rate activation energy of 0.73 eV was found. At low growth temperatures between 520 and 540°C, the surface morphology is poor due to antimonide precipitates associated with incomplete decomposition of the TMSb. For layers grown on GaAs at 580°C and 600°C with a V/III ratio of 3 a high quality surface morphology is typical, with a mirror-like surface and good composition control. It was found that a suitable growth temperature and V/III flux ratio was beneficial for producing good AlGaSb layers. Undoped AlGaSb grown at 580°C with a V/III flux ratio of 3 at the rate of 3.5 μm/hour shows p-type conductivity with smooth surface morphology

    Genomic differences between gut-resident bacterial strains likely underlie significant interindividual variation in microbiome function. Traditional methods of determining community composition, such as 16S rRNA gene amplicon sequencing, fail to capture this functional diversity. Metagenomic approaches are a significant step forward in identifying strain-level sequence variants; however, given the current paucity of biochemical information, they too are limited to mainly low-resolution and incomplete functional predictions. Using genomic, biochemical, and molecular approaches, we identified differences in the fructan utilization profiles of two closely related Bacteroides thetaiotaomicron strains. B. thetaiotaomicron 8736 ( Bt-8736 ) contains a fructan polysaccharide utilization locus (PUL) with a divergent susC / susD homolog gene pair that enables it to utilize inulin, differentiating this strain from other characterized Bt strains. Transfer of the distinct pair of susC / susD genes from Bt-8736 into the noninulin using type strain B. thetaiotaomicron VPI-5482 resulted in inulin use by the recipient strain, Bt ( 8736-2 ). The presence of the divergent susC / susD gene pair alone enabled the hybrid Bt ( 8736-2 ) strain to outcompete the wild-type strain in vivo in mice fed an inulin diet. Further, we discovered that the susC / susD homolog gene pair facilitated import of inulin into the periplasm without surface predigestion by an endo-acting enzyme, possibly due to the short average chain length of inulin compared to many other polysaccharides. Our data builds upon recent reports of dietary polysaccharide utilization mechanisms found in members of the Bacteroides genus and demonstrates how the acquisition of two genes can alter the functionality and success of a strain within the gut. IMPORTANCE Dietary polysaccharides play a dominant role in shaping the composition and functionality of our gut microbiota. Dietary interventions using these m icrobiota- a

    What is love and what part does it play in psychoanalysis? Where are the analyst and the analysand situated in relation to the roles defined as those of the "lover" and the "beloved"? Jacques Lacan explores these and other questions in his soon-to-be-published Seminar VIII: Transference by providing an extensive commentary on Plato's most famous dialogue on love, the Symposium. This paper outlines some of the major points about love that grow out of Lacan's reading of the dialogue and examines their relevance to the analytic setting. Can the analyst be characterized as a sort of modern-day Socrates?

    Human parvovirus B19 can be transmitted by coagulation factor concentrates and is highly resistant to virucidal methods. To evaluate whether the additional removal of virus by chromatographic methods during the manufacture of high-purity concentrates reduces the risk of B19 transmission, we have prospectively evaluated the rate of anti-B19 seroconversion in two groups of susceptible (anti-B19 negative) hemophiliacs infused with high-purity, heated (pasteurized) or solvent-detergent-treated factor VIII concentrates. Both products infected a relatively high proportion of patients (nine of 20).

    Thermo-mechanical treatment was given to improve further the superplastic behavior of SUS 304 stainless steel. In the SUS 304, martensite phase produced by the processing induced transformation may be reversely transformed to the primary austenite phase by high-temperature heating. Crystal grain size is micronized to 1 {mu} m by combining this reverse transformation and recrystallization of the austenite phase. However, the straining rate at that time is as extremely low as 1 times 10 {sup -4}/s or lower, which is insufficient for an industrial material. Therefore, the SUS 304 processed as described above was given again a series of thermo-mechanical treatment of the similar forced cold processing and annealing to ultra-micronize the crystalline particles. Majority of the crystalline particles have come to have a grain size of several hundred nm. This test piece showed a total elongation of 400% or more at a test temperature of 973 K and a straining rate of 1.8 times 10 {sup -3}/s or lower. In addition, the straining rate sensitivity index `m` at that time was 0.45 or higher. The superplastic deformation of the SUS 304 has a high possibility of being governed by dynamic recrystallization. 4 refs., 7 figs., 1 tab.

    M13 is a filamentous Escherichia coli virus covered with five types of capsid proteins, in which pVIII with ∼2700 copies was around the cylindered surface and pIII with five copies located at one end of the phage particle. The pIII-engineered M13 phages with enhanced binding specificity toward Fe were screened after five rounds of biopanning, and the one containing ATPTVAMSLSPL peptide at pIII-terminus was selected for mediated synthesis of zero valent (ZV) Fe nanoparticles (NPs) with the wild M13 as control. Under a reducing environment, uniformly dispersed ZVFeNPs with diameter of 5–10 nm were both synthesized and the morphologies after annealing were confirmed to be face-centered cubic type. The synthesized FeNPs mediated by the two phages showed no significant difference, revealing that the pVIII capsid did dominant contribution to metal binding in comparison with the pIII. A novel pVIII-engineered M13 containing AAEEEDPAK at terminus, named as 4ED-pVIII-M13, was constructed and it carried one more negatively charged residue than the wild one (AEGDDPAK). Metal adsorption quantification showed that the binding affinity of the 4ED-pVIII-M13 toward Ag and Ni ions improved to 62 and 18 % from original 21 and 6 %, respectively. The binding affinity toward Fe remained constant (∼85 %). ZVFe–Ag bi-NPs were successfully synthesized through mediation of 4ED-pVIII-M13. Particularly, the Fe:Ag ratio in the bi-NPs was conveniently controlled through changing the molar concentration of FeCl{sub 2} and AgNO{sub 3} solution before reduction.

Conclusión: Las enfermedades por anisakis y su consideración como enfermedad profesional, viene sujeta a la propia definición de lo que se considera así en nuestra norma legal, es decir que sea una enfermedad contraída como consecuencia del trabajo, en las actividades que se describen en el cuadro de enfermedades profesionales y por la acción del agente o sus sustancias que se recogen en el anexo I del actual cuadro. Además para que se admita como enfermedad profesional debemos de tener un diagnóstico firme (encuadrado en el cuadro de enfermedad profesional, un agente causal (recogido en el listado y una exposición al anisakis desarrollada en el ejercicio del trabajo (actividades recogidas en el listado. El listado o cuadro de enfermedad profesional es un sistema cerrado para agentes causales y enfermedades causadas, y la adscripción no es fácil. La parasitación tendría cabida en el grupo de enfermedades por agentes biológicos, la alergia podría discutirse su adscripción pero suele recogerse también en este grupo, el asma lo recogeríamos en el grupo de enfermedades respiratorias (causadas por inhalación dice el texto legal y las manifestaciones dérmicas en el grupo de las enfermedades profesionales de la piel. La exposición laboral al anisakis, es necesaria e imprescindible para que el proceso sea calificado de enfermedad profesional, pero esta exposición no siempre estará bien delimitada, y sin embargo debe estar probada. Puede haber existido una sensibilización fuera del trabajo y una aparición o desarrollo de la enfermedad por reiterada exposición o contacto con el anisakis en el trabajo lo que dificultará su calificación ocupacional.

    Educational graduates should have good competencies to compete in the 21st century. Integrated learning is a good way to develop competence of students in this century. Besides that, literacy skills are very important for students to get success in their learning and daily life. For this reason, integrated science learning and literacy skills are important in 2013 curriculum. However, integrated science learning and integration of literacy in learning can’t be implemented well. Solution of this problem is to develop adaptive contextual learning model by integrating digital age literacy. The purpose of the research is to determine the effectiveness of adaptive contextual learning model to improve competence of grade VIII students in junior high school. This research is a part of the research and development or R&D. Research design which used in limited field testing was before and after treatment. The research instruments consist of three parts namely test sheet of learning outcome for assessing knowledge competence, observation sheet for assessing attitudes, and performance sheet for assessing skills of students. Data of student’s competence were analyzed by three kinds of analysis, namely descriptive statistics, normality test and homogeneity test, and paired comparison test. From the data analysis result, it can be stated that the implementation of adaptive contextual learning model of integrated science by integrating digital age literacy is effective to improve the knowledge, attitude, and literacy skills competences of grade VIII students in junior high school at 95% confidence level.

    Despite proven benefits, prophylactic treatment for hemophilia A is hampered by the short half-life of factor VIII. A recombinant factor VIII-Fc fusion protein (rFVIIIFc) was constructed to determine the potential for reduced frequency of dosing. rFVIIIFc has an ∼ 2-fold longer half-life than rFVIII in hemophilia A (HemA) mice and dogs. The extension of rFVIIIFc half-life requires interaction of Fc with the neonatal Fc receptor (FcRn). In FcRn knockout mice, the extension of rFVIIIFc half-life is abrogated, and is restored in human FcRn transgenic mice. The Fc fusion has no impact on FVIII-specific activity. rFVIIIFc has comparable acute efficacy as rFVIII in treating tail clip injury in HemA mice, and fully corrects whole blood clotting time (WBCT) in HemA dogs immediately after dosing. Furthermore, consistent with prolonged half-life, rFVIIIFc shows 2-fold longer prophylactic efficacy in protecting HemA mice from tail vein transection bleeding induced 24-48 hours after dosing. In HemA dogs, rFVIIIFc also sustains partial correction of WBCT 1.5- to 2-fold longer than rFVIII. rFVIIIFc was well tolerated in both species. Thus, the rescue of FVIII by Fc fusion to provide prolonged protection presents a novel pathway for FVIII catabolism, and warrants further investigation. PMID:22246033

A 21-year-old football player, and otherwise healthy African American man, developed chest pain during exercise while bench-pressing 400 lbs. Acute MI was diagnosed based on physical examination, electrocardiography findings, and elevated cardiac enzymes. Coronary arteriography showed a thrombus occluding the proximal left anterior descending artery (LAD. Aggressive antiplatelet therapy with aspirin, clopidogrel, and eptifibatide was pursued, in addition to standard post-MI care. This led to the successful resolution of symptoms and dissolution of the thrombus, demonstrated by repeat coronary arteriography. Five months later, he presented with similar symptoms during exercise after lifting heavy weights, and was found to have another acute MI. Coronary arteriography again showed a thrombus occluding the LAD. No evidence of coronary artery dissection or vasospasm was found. Only mild atherosclerotic plaque burden was observed on both occasions by intravascular ultrasound. A bare metal stent was placed at the site as it was thought this site had acted as a nidus for small plaque rupture and thrombus formation. Elevated serum factor VIII activity at 205% (reference range 60%–140% was found, a rare cause of hypercoagulability. Further workup revealed a patent foramen ovale during a Valsalva maneuver by transesophageal echocardiography.

    Pharmacokinetics (PK) modelling suggests improvement of trough levels are achieved by using more frequent infusion strategy. However, no clinical study data exists to confirm or quantify improvement in trough level, particularly for low-dose prophylaxis in patients with haemophilia A. To provide evidence that low dose daily (ED) prophylaxis can increase trough levels without increasing FVIII consumption compared to every-other-day (EOD) infusion. A cross-over study on 5 IU kg -1 FVIII daily vs. 10 IU kg -1 EOD infusions, each for 14 days was conducted at the PUMCH-HTC. On the ED schedule, trough (immediate prior to infusion), and peak FVIII:C levels (30 min after infusion) were measured on days 1-5; and trough levels alone on days 7, 9, 11 and 13. For the EOD schedule, troughs, peaks and 4-h postinfusion were measured on day 1; troughs and peaks on days 3, 5, and 7; troughs alone on days 9, 11 and 13 and 24-h postinfusion on days 2, 4 and 6. FVIII inhibitors were assessed on days 0 and 14 during both infusion schedules. Six patients were enrolled. PK evidence showed that daily prophylaxis achieved higher (~2 times) steady-state FVIII trough levels compared to EOD with the same total factor consumption. The daily prophylaxis had good acceptability among patients and reduced chronic pain in the joints in some patients. Our PK study shows low-dose factor VIII daily infusion results in higher trough level than with EOD infusion with similar factor VIII consumption in Chinese adult haemophilia A patients. © 2017 John Wiley & Sons Ltd.

    In this paper, N-polar GaN films with different V/III ratios were grown on vicinal C-face SiC substrates by metalorganic chemical vapor deposition. During the growth of N-polar GaN film, the V/III ratio was controlled by adjusting the molar flow rate of ammonia while keeping the trimethylgallium flow rate unchanged. The influence of the V/III ratio on the surface morphology of N-polar GaN film has been studied. We find that the surface root mean square roughness of N-polar GaN film over an area of 20 × 20 μm2 can be reduced from 8.13 to 2.78 nm by optimization of the V/III ratio. Then, using the same growth conditions, N-polar InGaN/GaN multiple quantum wells (MQWs) light-emitting diodes (LEDs) were grown on the rough and the smooth N-polar GaN templates, respectively. Compared with the LED grown on the rough N-polar GaN template, dramatically improved interface sharpness and luminescence uniformity of the InGaN/GaN MQWs are achieved for the LED grown on the smooth N-polar GaN template.

  10. Hemophilia as a defect of the tissue factor pathway of blood coagulation: Effect of factors VIII and IX on factor X activation in a continuous-flow reactor

    1990-01-01

    The effect of factors VIII and IX on the ability of the tissue factor-factor VIIa complex to activate factor X was studied in a continuous-flow tubular enzyme reactor. Tissue factor immobilized in a phospholipid bilayer on the inner surface of the tube was exposed to a perfusate containing factors VIIa, VIII, IX, and X flowing at a wall shear rate of 57, 300, or 1130 sec -1 . The addition of factors VIII and IX at their respective plasma concentrations resulted in a further 2 endash-to 3 endash fold increase. The direct activation of factor X by tissue factor-factor VIIa could be virtually eliminated by the lipoprotein-associated coagulation inhibitor. These results suggest that the tissue factor pathway, mediated through factors VIII and IX, produces significant levels of factor Xa even in the presence of an inhibitor of the tissue factor-factor VIIa complex; moreover, the activation is dependent on local shear conditions. These findings are consistent both with a model of blood coagulation in which initiation of the system results from tissue factor and with the bleeding observed in hemophilia

    Highlights: • Four SUS solutions are established to help reactors complete the start-up process. • Solutions C and D lead to superior behaved than Solutions A and B. • Solution C is fit for propulsion reactors and Solution D for nuclear power reactors. - Abstract: In this paper, we report on research that has been carried out both on the comparison and evaluation of four designed Start-up Systems (SUSs), which are proposed to improve reliability and economy during the reactor start-up process. Firstly, four SUS solutions are established to satisfy demands and detailed descriptions are introduced. Then, four reactor systems, which include SUS, are modeled by the estimate code JTopmeret. Furthermore besides, the JTopmeret code is validated for the once-through steam generators (OTSG). Finally, the behaviors of SUS and the steady and transient performance of OTSG are investigated. The results show that the designed SUS can successfully improve the economy and the OTSG operational safety. Suggestion is made in this paper to apply Solution C in propulsion-purposed reactors, and Solution D in nuclear power reactors

    The distribution of residual stress of SUS304 samples that were undergone TIG welding process with four different electric currents has been measured. The welding has been done in the middle part of the samples that was previously grooved by milling machine. Before they were welded the samples were annealed at 650 degree Celsius for one hour. The annealing process was done to eliminate residual stress generated by grooving process so that the residual stress within the samples was merely produced from welding process. The calculation of distribution of residual stress was carried out by measuring the strains within crystal planes of Fe(220) SUS304. Strain, Young modulus, and Poisson ratio of Fe(220) SUS304 were measured using DN1-M neutron diffractometer. Young modulus and Poisson ratio of Fe(220) SUS304 sample were measured in-situ. The result of calculations showed that distribution of residual stress of SUS304 in the vicinity of welded area is influenced both by treatments given at the samples-making process and by the electric current used during welding process.

    Highlights: • The microstructure of F82H/SUS316L dissimilar joint can be divided into four regions. • In the case without beam position shift, hardness of WM cannot be reduced by PWHT. • The fiber laser welding would be applicable for constructing the dissimilar joint. -- Abstract: As one of the high beam quality heat sources, 4 kW fiber laser was applied for joining between reduced activation ferritic/martensitic steel, F82H and SUS316L austenitic stainless steel, and the microstructural analyses and Vickers hardness measurements were carried out before and after post-weld heat treatment (PWHT). The microstructure of joint can be divided into four regions which are base metal of F82H, heat affected zone (HAZ) in F82H, weld metal (WM) and base metal of SUS316L. Also, it is revealed that the high-power fiber laser can be employed for constructing butt joint between F82H and SUS316L by applying PWHT and shifting the laser beam position to SUS316L, where the distance between the contact face and beam should be set as a range from radius to diameter of laser beam.

    SUS-MI cables are the inorganic insulation cables using austenitic stainless steel SUS 321 as the sheath, oxygen-free copper as the conductor and high purity magnesium oxide as the insulatingmaterial. Because of the excellent characteristics of the composing materials, the properties withstanding radiation, fire and heat, and sodium of the cables are superior. In the nuclear power facilities being developed such as fast breeder reactors and nuclear fusion reactors, there is the environment the cables with organic materials as the components cannot meet. As the cables to be applied to such places, the SUS-MI cables are most suitable. In this report, the electric properties and the mechanical strength of the cables and the examples of practical use are described. The highest temperature of using the SUS-MI cables is 800 deg C. The form and the composing materials of the SUS-MI cables, the characteristics and the cable laying are reported. Ceramic connectors and heat-resistant wall penetration parts were developed. The characteristics of the cables for the preheaters of fast breeder reactors are compared. (Kako, I.)

    Muchas teorías contemporáneas han intentado fundamentar una teoría de la justicia en alguna forma de consenso, sea fáctico o hipotético. Pero esa vía presenta muchas dificultades teóricas que la vuelven difícilmente aceptable. Un consenso posible podría fundarse en una voluntad ética desprendida de actitudes excluyentes y no a la inversa. Cabe pues explorar una alternativa: dar razón de la idea de justicia por la voluntad de disrupcion de una situación percibida como injusta. Eso es lo que ha acontecido históricamente y, así, la teoría de la justicia se remitiría a esa experiencia de hecho y partiría de su examen crítico. Procedería en dos partes. Primero, la caracterización de la injusticia cuyo principio es la exclusión. Ésta puede definirse como la no-pertenencia a una asociación civil dada, de personas que pertenecen a la comunidad de los hombres. La percepción de la exclusión nos llevaría a determinar tanto los requisitos de pertenencia a una asociación civil como las exigencias planteadas por compartir la condición humana. Segundo, el análisis de las principales formas de exclusión y sus modalidades. De ese análisis podrían deducirse los principios de una teoría de la justicia que partiera del rechazo de una situación de exclusión real, sea o no objeto de consenso.

    The method is presented of separating the ions of the elements of the periodic system groups III, IV, and VIII by ion exchangers. The ions are complex-bonded to a new type of ion exchanger consisting of the polycondensates of phenol with aldehydes or ketones and containing an atom of phosphorus, arsenic or antimony with an atom of sulphur or oxygen in a complex bond. The polymers of compounds containing a double bond, e.g., of butadiene, polyvinyl alcohol, polyethylene, polypropylene, and the compounds of styrene with fural may also be used for this purpose. The method is demonstrated on a case of uranium and heavy metal concentration and the separation thereof from waste waters. (L.K.)

Although this is the first time the Proceedings of a Meeting in this series are published, ''Fisica Estasdistica'' dates back to 1986, when about fifty Spanish scientists attended the first edition in Barcelona. That first Meeting was organized by a group of young and not so young physicists who wanted to set up a national conference of an international level and with a broader, more interdisciplinary scope than others held at that time. Their idea quickly got off the ground and following the first edition, sequels took place every year and a half: Palma de Mallorca (1988), Badajoz (1990), Cabuenas, Asturies (1991), El Escorial, Madrid (1993), Sevilla (1994), and Zaragoza (1996)

    Thrombomodulin (TM) is a newly described endothelial cell-associated protein that functions as a potent natural anticoagulant by converting thrombin from a procoagulant protease to an anticoagulant. Various vascular tumors were characterized with immunoperoxidase staining with the use of a polyclonal anti-TM serum. The staining patterns of TM were compared with those of Factor VIII-related antigen (FVIII-RAG) and Ulex europaeus agglutinin-I (UEA-I), which have been used as markers for endothelial cells. The results showed that TM is a specific and a highly sensitive marker for angiosarcomas in comparison with FVIII-RAG or UEA-I. In contrast, UEA-I is more sensitive for benign vascular tumors than TM or FVIII-RAG. The other mesenchymal tumors of nonvascular origin showed negative staining for three endothelial markers. These results indicate that TM is a new specific and sensitive tool for the diagnosis of angiosarcomas.

    Introduction The most serious complication in haemophilia A (HA) replacement therapy with coagulation factor VIII (FVIII) is neutralizing antibodies, i.e. inhibitors. It has been hypothesized that danger signals generated during a bleed might have an adjuvant effect on the immune response to FVIII...... in on-demand treatment, increasing the inhibitor risk. Aim To compare the antibody response to treatment with recombinant human FVIII (rhFVIII) in relation to induced knee joint bleeds and treatment without concurrent bleeds in a HA rat model. Method HA rats were divided into two groups: one group (n...... = 10) receiving three needle induced knee joint bleeds 14 days apart and a control group (n = 9) receiving three sham procedures. Three hours after each injury/sham 50 IU kg−1 rhFVIII was administrated intravenously. Subsequently, both groups continued rhFVIII treatment for another 9 weeks. Binding...

    Ramsay Hunt syndrome is a rare complication of the varicella zoster virus, defined as a peripheral facial palsy that typically results from involvement of the facial and auditory nerves. Ramsay Hunt syndrome can be associated with cranial nerves V, VI, IX, and X but rarely with XII. We describe an atypical case of Ramsay Hunt syndrome with multiple cranial nerve involvement of nerves V, VII, VIII, and XII. Antiviral drugs, antibiotics, insulin, and traditional Chinese drugs were administered immediately after admission. After 3 months of combination therapy, the patient had recovered satisfactorily. Herpes zoster can cause severe infections in diabetic patients and should be treated as soon after detection as possible. Ramsay Hunt syndrome should be recognized as a polycranial neuritis characterized by damage to sensory and motor nerves. In addition to facial and vestibular nerve paralysis, Ramsay Hunt syndrome may also involve cranial nerves V and XII.

  5. Short-range order in alloys of nickel with the elements of group VIII of the periodic table

    Experimental measurements of the diffuse X-ray scattering intensity were performed on alloys of Ni with Rh and Os. The atomic short-range order (SRO) parameters αsub(i) and the size-effect parameters βsub(i) were calculated from these measurements. It is established that SRO and size-effect exist in Ni-Rh and Ni-Os alloys analogously as in a few other alloys of Ni with the elements of group VIII of the periodic table. The experimental data was interpreted theoretically by calculating the interaction energies from the pseudo-potentials and the effective valencies of the individual components of the systems studied. It was found that theoretically calculated values of the interaction energies for these alloys are inconsistent with the experimentally determined sign of the SRO parameter. (author)

    Hepatectomy is the optimal method for liver cancer; the virtual liver resection based on three-dimensional visualization technology (3-DVT) could provide better preoperative strategy for surgeon. We aim to introduce right posterior lobe allied with part of V and VIII sectionectomy assisted by 3-DVT as a promising treatment for massive or multiple right hepatic malignancies to retain maximum residual liver volume on the basis of R0 resection. Among 126 consecutive patients who underwent hepatectomy, 9 (7%) underwent right posterior lobe allied with part of V and VIII sectionectomy. 21 (17%) underwent right hemihepatectomy (RH). The virtual RH was performed with 3-DVT, which provided better observation of spatial position relationship between tumor and vessels, and the more accurate estimation of the remnant liver volume. If remnant liver volume was right posterior lobe allied with part of V and VIII sectionectomy should be undergone. Then, the precut line ought to be planned on the basis of protecting the portal branch of subsegment 5 and 8. The postoperative outcome of patients was compared before and after propensity score matching. Nine patients meeting the eligibility criteria received right posterior lobe allied with part of V and VIII sectionectomy. The variables, including the overall mean operation time, blood transfusion, operation length, liver function, and postoperative complications, were similar between two groups before and after propensity matching. The postoperative first, third, fifth, and seventh days mean value of aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin (ALB), and total bilirubin had no significant difference compared with preoperative value. One patient in each group had recurrence six months after surgery. Right posterior lobe allied with part of V and VIII sectionectomy based on 3-DVT is safe and feasible surgery way, and can be a very promising method in massive or multiple right hepatic malignancy therapy.

Sucrose synthase, which reversibly catalyzes sucrose synthesis and cleavage, represents a key enzyme in the control of the flow of carbon into starch biosynthesis. In the present study the genomic identification and characterization of the Sus2-2A and Sus2-2B genes coding for sucrose synthase in durum wheat (cultivars Ciccio and Svevo is reported. The genes were analyzed for their expression in different tissues and at different seed maturation stages, in four tetraploid wheat genotypes (Svevo, Ciccio, Primadur and 5-BIL42. The activity of the encoded proteins was evaluated by specific activity assays on endosperm extracts and their structure established by modelling approaches. The combined results of SUS2 expression and activity levels were then considered in the light of their possible involvement in starch yield.

    Essentials Platelet-Factor (F) VIII gene therapy is a promising treatment in hemophilia A. This study aims to evaluate if platelet-FVIII expression would increase the risk for thrombosis. Targeting FVIII expression to platelets does not induce or elevate thrombosis risk. Platelets expressing FVIII are neither hyper-activated nor hyper-responsive. Background Targeting factor (F) VIII expression to platelets is a promising gene therapy approach for hemophilia A, and is successful even in the presence of inhibitors. It is well known that platelets play important roles not only in hemostasis, but also in thrombosis and inflammation. Objective To evaluate whether platelet-FVIII expression might increase thrombotic risk and thereby compromise the safety of this approach. Methods In this study, platelet-FVIII-expressing transgenic mice were examined either in steady-state conditions or under prothrombotic conditions induced by inflammation or the FV Leiden mutation. Native whole blood thrombin generation assay, rotational thromboelastometry analysis and ferric chloride-induced vessel injury were used to evaluate the hemostatic properties. Various parameters associated with thrombosis risk, including D-dimer, thrombin-antithrombin complexes, fibrinogen, tissue fibrin deposition, platelet activation status and activatability, and platelet-leukocyte aggregates, were assessed. Results We generated a new line of transgenic mice that expressed 30-fold higher levels of platelet-expressed FVIII than are therapeutically required to restore hemostasis in hemophilic mice. Under both steady-state conditions and prothrombotic conditions induced by lipopolysaccharide-mediated inflammation or the FV Leiden mutation, supratherapeutic levels of platelet-expressed FVIII did not appear to be thrombogenic. Furthermore, FVIII-expressing platelets were neither hyperactivated nor hyperactivatable upon agonist activation. Conclusion We conclude that, in mice, more than 30-fold higher levels of

  11. Production of factor VIII by human liver sinusoidal endothelial cells transplanted in immunodeficient uPA mice.

    Full Text Available Liver sinusoidal endothelial cells (LSECs form a semi-permeable barrier between parenchymal hepatocytes and the blood. LSECs participate in liver metabolism, clearance of pathological agents, immunological responses, architectural maintenance of the liver and synthesis of growth factors and cytokines. LSECs also play an important role in coagulation through the synthesis of Factor VIII (FVIII. Herein, we phenotypically define human LSECs isolated from fetal liver using flow cytometry and immunofluorescence microscopy. Isolated LSECs were cultured and shown to express endothelial markers and markers specific for the LSEC lineage. LSECs were also shown to engraft the liver when human fetal liver cells were transplanted into immunodeficient mice with liver specific expression of the urokinase-type plasminogen activator (uPA transgene (uPA-NOG mice. Engrafted cells expressed human Factor VIII at levels approaching those found in human plasma. We also demonstrate engraftment of adult LSECs, as well as hepatocytes, transplanted into uPA-NOG mice. We propose that overexpression of uPA provides beneficial conditions for LSEC engraftment due to elevated expression of the angiogenic cytokine, vascular endothelial growth factor. This work provides a detailed characterization of human midgestation LSECs, thereby providing the means for their purification and culture based on their expression of CD14 and CD32 as well as a lack of CD45 expression. The uPA-NOG mouse is shown to be a permissive host for human LSECs and adult hepatocytes, but not fetal hepatoblasts. Thus, these mice provide a useful model system to study these cell types in vivo. Demonstration of human FVIII production by transplanted LSECs encourages further pursuit of LSEC transplantation as a cellular therapy for the treatment of hemophilia A.

    Highlights: • The role of oxide particles in α/α′ phase decomposition behavior; microstructure of phase decomposition observed by TEM. • The characteristics of ductility loss caused by age-hardening. • Correlation of phase decomposition and age-hardening explained by dispersion strengthened models. • Age-hardening susceptibility of ODS steels and SUS430 steel. - Abstract: The effect of aging on high-Cr ferritic steels was investigated with focusing on the role of oxide particles in α/α′ phase decomposition behavior. 12Cr-oxide dispersion strengthened (ODS) steel, 15Cr-ODS steel and commercial SUS430 steel were isothermally aged at 475 °C for up to 10,000 h. Thermal aging caused a larger hardening in SUS430 than 15Cr-ODS, while 12Cr-ODS showed almost no hardening. A characteristic of the ODS steels is that the hardening was not accompanied by the significant loss of ductility that was observed in SUS430 steel. After aging for 2000 h, SUS430 steel shows a larger ductile–brittle transition temperature (DBTT) shift than 15Cr-ODS steel, which suggests that the age-hardening susceptibility is lower in 15Cr-ODS steel than in conventional SUS430 steel. Thermal aging leaded to a large number of Cr-rich α′ precipitates, which were confirmed by transmission electron microscopy (TEM). Correlation of age-hardening and phase decomposition was interpreted by Orowan type strengthening model. Results indicate that oxide particles cannot only suppress ductility loss, but also may influence α/α′ phase decomposition kinetics.

    The molecular defect responsible for moderate and severe hemophilia A has been identified for two unrelated patients with the CRM-positive form of this disorder (factor VIII activity of 0.02 and 0.05 U/mL with factor VIII antigen of 0.87 and 2.20 U/mL). In both cases, the immunopurified dysfunctional factor VIII protein is abnormal, in that the 80 Kd light chain is not cleaved by thrombin at arginine-1689. The basis for this failure was identified by polymerase chain reaction amplification of exon 14 of the variant factor VIII genes and direct sequencing of the amplified products. In both cases, a single base substitution (C to T) was identified that produces an arginine to cysteine substitution at amino acid residue 1689. These data identify the molecular defects of the two identical factor VIII variant proteins. The dysfunctional factor VIII has been designated "Factor VIII-East Hartford," the residence of the patient in whom the defect was first identified.

    The effects of growth conditions such as Mg/Ga and V/III ratios on the properties of N-polar (000\\bar{1}) p-type GaN grown by metalorganic vapor phase epitaxy were studied. Photoluminescence spectra from Mg-doped GaN depended on Mg/Ga and V/III ratios. For the lightly doped samples, the band-to-acceptor emission was observed at 3.3 eV and its relative intensity decreased with increasing V/III ratio. For the heavily doped samples, the donor-acceptor pair emission was observed at 2.8 eV and its peak intensity monotonically decreased with V/III ratio. The hole concentration was maximum for the Mg/Ga ratio. This is the same tendency as in group-III polar (0001) growth. The V/III ratio also reduced the hole concentration. The higher V/III ratio reduced the concentration of residual donors such as oxygen by substituting nitrogen atoms. The surface became rougher with increasing V/III ratio and the hillock density increased.

    Full Text Available Introduction: between 2000 to 2011, Diadema paulista municipality has faced many obstacles in health management, struggling to ensure the sustainability of its health system. Objective: to contribute to the discussion of the Unified Health System (SUS and its foreseable turbulent future, based on the analysis of the municipal point of view, identifying the limits of its building in Diadema. Methods: Diadema is characterized as one of the first municipalities that adhered to the principles of the SUS, since its implementation, allowing an analysis as a case study in view of the system's sustainability at the local level. The term sustainability used was addressed in two dimensions: the structure of this system and its process. Results: in SUS implementation period, Diadema stood out by increasing investment in health, reaching an average allocation of about 30% of its tax revenues, including constitutional transfers. Results diagnosed by observing the structure of dimensions and the process indicate that the sustainability of the municipal health system is threatened, as the significant expansion of the range of services and health actions was not followed by sufficient resources to its health maintenance. Conclusions: the existence of obstacles justified and formed the basis for the diagnosis of the main limits on SUS conformation, in health policy and management of resources, funding and budgetary impacts.

    Structural materials used in radiation environments require radiation tolerance and sufficient mechanical properties in the controlled state. In order to offer SUS316L austenitic stainless steel with the assumed requirements, nanostructured SUS316L with TiC addition of 2% (SUS316L-2TiC) that is capable of exhibiting enhanced tensile ductility and flow strength sufficient for structural applications was fabricated by advanced powder metallurgical methods. The methods include MA (Mechanical Alloying), HIP (Hot Isostatic Pressing), GSMM (Grain boundary Sliding Microstructural Modification) for ductility enhancement, cold rolling at temperatures below Md (the temperature where the martensite phase occurs by plastic deformation) for phase transformation from austenite to martensite and heat treatment for reverse transformation from martensite to austenite. It is shown that the developed SUS316L-2TiC exhibits ultrafine grains with sizes of 90-270 nm, accompanied by TiC precipitates with 20-50 nm in grain interior and 70-110 nm at grain boundaries, yield strengths of 1850 to 900 MPa, tensile strengths of 1920 to 1100 MPa and uniform elongations of 0.6-21%, respectively, depending on the heat treatment temperature after rolling at -196 °C.

Following this, some Colleges have implemented a Rural Internship (RI discipline, as a way to promote: a adequate information on the SUS, and b students' interaction with pharmaceutical assistance. In this study we analyzed the perceptions of students enrolled in the Rural Internship program of the undergraduate Pharmacy Program at the Federal University of Minas Gerais. Eight students participated in this study and their perceptions and ideas were obtained by focus groups, both before and after the RI. This information was analyzed by content analysis. The students had a fragmented, distorted view on assistance, before as well as after taking the RI. Nevertheless, the RI provided students with a view of the professional realities and difficulties routinely faced by pharmacists in the public health system. The RI course of the Pharmacy Programs was viewed as an opportunity to improve the professional work within the SUS.As Diretrizes Curriculares de 2002 implantaram um novo currículo para o Curso de Farmácia, trazendo como propósito a aprendizagem para o Sistema Único de Saúde (SUS.

Most reported small-molecule inhibitors targeting the ALK domain do not display good inhibition of the G1202R solvent front mutation. The solvent front mutation was assumed to hinder drug binding. However, a different fact could be uncovered by the simulations reported in this study through a structural analog of alectinib (JH-VIII-157-02, which demonstrated potent effects against the G1202R mutation. Methods: Molecular docking, conventional molecular dynamics (MD simulations, free energy calculations, and umbrella sampling (US simulations were carried out to make clear the principles of the binding preferences of alectinib and JH-VIII-157-02 toward ALKWT and the ALK G1202R (ALKG1202R mutation. Results: JH-VIII-157-02 has similar binding affinities to both ALKWT and ALKG1202R whereas it has has a much lower binding affinity for alectinib to ALKG1202R. Analysis of individual energy terms indicate the major variation involves the van der Waals and entropy terms. Structural analysis reveals that the conformational change of the ATP-binding glycine-rich loop was primarily responsible for the alectinib

    Essentials Immunologic methods detect factor VIII (FVIII) antibodies in some inhibitor-negative specimens. Specimens were tested by modified Nijmegen-Bethesda assay (NBA) and fluorescence immunoassay. The NBA with preanalytical heat inactivation detects FVIII inhibitors down to 0.2 NBU. IgG 4 frequency validates the established threshold for positivity of ≥ 0.5 NBU for this NBA. Background The Bethesda assay for measurement of factor VIII inhibitors called for quantification of positive inhibitors by using dilutions producing 25-75% residual activity (RA), corresponding to 0.4-2.0 Bethesda units, with the use of 'more sensitive methods' for samples with RA closer to 100% being recommended. The Nijmegen modification (Nijmegen-Bethesda assay [NBA]) changed the reagents used but not these calculations. Some specimens negative by the NBA have been shown to have FVIII antibodies detectable with sensitive immunologic methods. Objective To examine the performance at very low inhibitor titers of the Centers for Disease Control and Prevention (CDC)-modified NBA (CDC-NBA), which includes preanalytic heat inactivation to liberate bound anti-FVIII antibodies. Methods Specimens with known inhibitors were tested with the CDC-NBA. IgG 4 anti-FVIII antibodies were measured by fluorescence immunoassay (FLI). Results Diluted inhibitors showed linearity below 0.4 Nijmegen-Bethesda units (NBU). With four statistical methods, the limit of detection of the CDC-NBA was determined to be 0.2 NBU. IgG 4 anti-FVIII antibodies, which correlate most strongly with functional inhibitors, were present at rates above the background rate of healthy controls in specimens with titers ≥ 0.2 NBU and showed an increase in frequency from 14.3% at 0.4 NBU to 67% at the established threshold for positivity of 0.5 NBU. Conclusions The CDC-NBA can detect inhibitors down to 0.2 NBU. The FLI, which is more sensitive, demonstrates anti-FVIII IgG 4 in some patients with negative (NBA, supporting the need for

    Full Text Available In cases of Dengue fever, late hospital admission can lead to treatment delay and even death. In order to improve early disease notification and management, it is essential to investigate the factors affecting the time of admission of Dengue cases. This study determined the factors associated with the time of admission among notified Dengue cases. The study covered the period between 2008 and 2014 in Region VIII, Philippines. The factors assessed were age, sex, hospital sector, hospital level, disease severity based on the 1997 WHO Dengue classification, and period of admission (distinguishing between the 2010 Dengue epidemic and non-epidemic time. We analysed secondary data from the surveillance of notified Dengue cases. We calculated the association through chi-square test, ordinal logistic regression and linear regression at p value < 0.05. The study included 16,357 admitted Dengue cases. The reported cases included a majority of children (70.09%, mild cases of the disease (64.00%, patients from the public sector (69.82%, and non-tertiary hospitals (62.76%. Only 1.40% of cases had a laboratory confirmation. The epidemic period in 2010 comprised 48.68% of all the admitted cases during this period. Late admission was more likely among adults than children (p<0.05. The severe type of the disease was more likely to be admitted late than the mild type (p<0.05. Late admission was also more likely in public hospitals than in private hospitals (p<0.05; and within tertiary level hospitals than non-tertiary hospitals (p<0.05. Late admission was more likely during the non-epidemic period than the 2010 epidemic period (p<0.05. A case fatality rate of 1 or greater was significantly associated with children, severe diseases, tertiary hospitals and public hospitals when admitted late (p<0.05. Data suggests that early admission among child cases was common in Region VIII. This behavior is encouraging, and should be continued. However, further study is needed

    Essentials Factor (F) VIII is an inefficiently expressed protein. Furin deletion FVIII variants were purified and characterized using in vitro and in vivo assays. These minimally modified novel FVIII variants have enhanced function. These variants provide a strategy for increasing FVIII expression in hemophilia A gene therapy. Background The major challenge for developing gene-based therapies for hemophilia A is that human factor VIII (hFVIII) has intrinsic properties that result in inefficient biosynthesis. During intracellular processing, hFVIII is predominantly cleaved at a paired basic amino acid cleaving enzyme (PACE) or furin cleavage site to yield a heterodimer that is the major form of secreted protein. Previous studies with B-domain-deleted (BDD) canine FVIII and hFVIII-R1645H, both differing from hFVIII by a single amino acid at this site, suggested that these proteins are secreted mainly in a single polypeptide chain (SC) form and exhibit enhanced function. Objective We hypothesized that deletion(s) of the furin site modulates FVIII biology and may enhance its function. Methods A series of recombinant hFVIII-furin deletion variants were introduced into hFVIII-BDD [Δ1645, 1645-46(Δ2), 1645-47(Δ3), 1645-48(Δ4), or Δ1648] and characterized. Results In vitro, recombinant purified Δ3 and Δ4 were primarily SC and, interestingly, had 2-fold higher procoagulant activity compared with FVIII-BDD. In vivo, the variants also have improved hemostatic function. After adeno-associated viral (AAV) vector delivery, the expression of these variants is 2-4-fold higher than hFVIII-BDD. Protein challenges of each variant in mice tolerant to hFVIII-BDD showed no anti-FVIII immune response. Conclusions These data suggest that the furin deletion hFVIII variants are superior to hFVIII-BDD without increased immunogenicity. In the setting of gene-based therapeutics, these novel variants provide a unique strategy to increase FVIII expression, thus lowering the vector dose, a

    We describe the new ENDF/B-VIII.0 evaluated nuclear reaction data library. ENDF/B-VIII.0 fully incorporates the new IAEA standards, includes improved thermal neutron scattering data and uses new evaluated data from the CIELO project for neutron reactions on 1H, 16O, 56Fe, 235U, 238U and 239Pu described in companion papers in the present issue of Nuclear Data Sheets. The evaluations benefit from recent experimental data obtained in the U.S. and Europe, and improvements in theory and simulation. Notable advances include updated evaluated data for light nuclei, structural materials, actinides, fission energy release, prompt fission neutron and γ-ray spectra, thermal neutron scattering data, and charged-particle reactions. Integral validation testing is shown for a wide range of criticality, reaction rate, and neutron transmission benchmarks. In general, integral validation performance of the library is improved relative to the previous ENDF/B-VII.1 library.

    Deep level transient spectroscopy (DLTS) and deep level optical spectroscopy (DLOS) were utilized to investigate the behavior of deep states in m-plane, n-type GaN grown by ammonia-based molecular beam epitaxy (NH 3 -MBE) as a function of systematically varied V/III growth flux ratios. Levels were detected at E C - 0.14 eV, E C - 0.21 eV, E C - 0.26 eV, E C - 0.62 eV, E C - 0.67 eV, E C - 2.65 eV, and E C - 3.31 eV, with the concentrations of several traps exhibiting systematic dependencies on V/III ratio. The DLTS spectra are dominated by traps at E C - 0.14 eV and E C - 0.67 eV, whose concentrations decreased monotonically with increasing V/III ratio and decreasing oxygen impurity concentration, and by a trap at E C - 0.21 eV that revealed no dependence of its concentration on growth conditions, suggestive of different physical origins. Higher concentrations of deeper trap states detected by DLOS with activation energies of E C - 2.65 eV and E C - 3.31 eV in each sample did not display measureable sensitivity to the intentionally varied V/III ratio, necessitating further study on reducing these deep traps through growth optimization for maximizing material quality of NH 3 -MBE grown m-plane GaN.

    Vascular loops in the cerebellopontine angle (CPA) and their relationship to cranial nerves have been used to explain neurological symptoms. The anterior inferior cerebellar artery (AICA) has variable branches producing vascular loops that can compress the facial cranial nerve (CN) VII and vestibulocochlear (CN VIII) nerves. AICA compression of the facial-vestibulocochlear nerve complex can lead to various clinical presentations, including hemifacial spasm (HFS), tinnitus, and hemiataxia. The formation of arterial loops inside or outside of the internal auditory meatus (IAM) can cause abutment or compression of CN VII and CN VIII. Twenty-five (50 sides) fresh adult cadavers underwent dissection of the cerebellopontine angle in the supine position. In regard to relationships between the AICA and the nerves of the facial/vestibulocochlear complex, 33 arteries (66%) traveled in a plane between the facial/nervus intermedius nerves and the cochlear and vestibular nerves. Five arteries (10%) traveled below the CN VII/VIII complex, six (12%) traveled posterior to the nerve complex, four (8%) formed a semi-circle around the upper half of the nerve complex, and two (4%) traveled between and partially separated the nervus intermedius and facial nerve proper. Our study found that the majority of AICA will travel in a plane between the facial/nervus intermedius nerves and the cochlear and vestibular nerves. Although the relationship between the AICA and porus acusticus and AICA and the nerves of the CN VII/VIII complex are variable, based on our findings, some themes exist. Surgeons should consider these with approaches to the cerebellopontine angle.

    The crystal structure of BT-3984, a SusD-family protein, reveals a TPR N-terminal region providing support for a loop-rich C-terminal subdomain and suggests possible interfaces involved in sus complex formation. The crystal structure of the Bacteroides thetaiotaomicron protein BT-3984 was determined to a resolution of 1.7 Å and was the first structure to be determined from the extensive SusD family of polysaccharide-binding proteins. SusD is an essential component of the sus operon that defines the paradigm for glycan utilization in dominant members of the human gut microbiota. Structural analysis of BT-3984 revealed an N-terminal region containing several tetratricopeptide repeats (TPRs), while the signature C-terminal region is less structured and contains extensive loop regions. Sequence and structure analysis of BT-3984 suggests the presence of binding interfaces for other proteins from the polysaccharide-utilization complex

    The effects of growth temperature and V/III ratio on the InN initial nucleation of islands on the GaN (0 0 0 1) surface were investigated. It is found that InN nuclei density increases with decreasing growth temperature between 375 and 525 °C. At lower growth temperatures, InN thin films take the form of small and closely packed islands with diameters of less than 100 nm, whereas at elevated temperatures the InN islands can grow larger and well separated, approaching an equilibrium hexagonal shape due to enhanced surface diffusion of adatoms. At a given growth temperature of 500 °C, a controllable density and size of separated InN islands can be achieved by adjusting the V/III ratio. The larger islands lead to fewer defects when they are coalesced. Comparatively, the electrical properties of the films grown under higher V/III ratio are improved

    The identification of infrequent side-effects of clotting factor concentrates, undetected by clinical trials, is facilitated by post-marketing surveillance. We present a post-marketing surveillance study in which 97 patients with haemophilia A, attending three haemophilia centres, were treated over a median follow-up period of 284 days (range 1-1074), and a total follow-up period of 30,080 days, with a pasteurized immunoaffinity purified factor VIII concentrate (Monoclate-P, Armour, Collegeville, USA). 5216 infusions, using 10,527,000 units of Monoclate-P, were carried out, mostly for routine haemarthroses or prophylaxis. No new inhibitors were observed during the study. At the start of the study 60/97 were HIV seropositive, 67/97 HBs antibody positive, 12 HbsAb negative and the remainder HBsAb positive before the study period. 13/14 tested were HAV seropositive at the beginning of the study. One patient became HAV seropositive during the study period, an infection thought to be community acquired. No other seroconversions were observed. Only one mild transfusion reaction was observed. This study confirms the safety and efficacy of Monoclate-P. Post-marketing surveillance or nationally organized pharmaco-vigilance should be practiced more widely to enable identification of low-frequency side-effects of treatment.

    Full Text Available We present a direct observation of the M1 transition between the fine structure splitting in the 4 f 13 5 s 2 5 p 6 2 F ground term of W VIII. The spectroscopic data of few-times ionized tungsten ions are important for the future ITER diagnostics, but there is a serious lack of data. The present study is part of an ongoing effort to solve this problem. Emission from the tungsten ions produced and trapped in a compact electron beam ion trap is observed with a Czerny–Turner visible spectrometer. Spectra in the EUV range are also observed at the same time to help identify the previously-unreported visible lines. The observed wavelength 574.47 ± 0.03 nm (air, which corresponds to the fine structure splitting of 17,402.5 ± 0.9 cm − 1 , shows reasonable agreement with the previously reported value 17,410 ± 5 cm − 1 obtained indirectly through the analysis of EUV spectra [Ryabtsev et al., Atoms 3 (2015 273].

    The role of prophylactic factor VIII (FVIII) to decrease hemophilic bleeding and arthropathy is well established. The rationale for this strategy is to convert patients with severe hemophilia A to a moderate clinical phenotype by reducing time spent with a FVIII level break-through bleeding in patients with severe hemophilia A on prophylaxis. This study analysed data from 44 patients aged 1-6 and 99 patients aged 10-65 years with severe hemophilia A (FVIII safety and efficacy of a recombinant FVIII (Advate). Each patient had pharmacokinetic measurements and FVIII infusions recorded, and these were used to calculate time spent with a FVIII below 1, 2 and 5 IU dL(-1). The data demonstrate that increasing time with a FVIII below 1 IU dL(-1) is associated with increased total bleeds and hemarthroses. Lack of adherence to the intended frequency of FVIII infusion was the most important determinant of low FVIII and increased bleeding. In children aged 1-6 years, the rate of bleeding was also influenced by FVIII half-life and clearance. These data have important implications for the management of patients with severe hemophilia.

    In cases of Dengue fever, late hospital admission can lead to treatment delay and even death. In order to improve early disease notification and management, it is essential to investigate the factors affecting the time of admission of Dengue cases. This study determined the factors associated with the time of admission among notified Dengue cases. The study covered the period between 2008 and 2014 in Region VIII, Philippines. The factors assessed were age, sex, hospital sector, hospital level, disease severity based on the 1997 WHO Dengue classification, and period of admission (distinguishing between the 2010 Dengue epidemic and non-epidemic time). We analysed secondary data from the surveillance of notified Dengue cases. We calculated the association through chi-square test, ordinal logistic regression and linear regression at p value Dengue cases. The reported cases included a majority of children (70.09%), mild cases of the disease (64.00%), patients from the public sector (69.82%), and non-tertiary hospitals (62.76%). Only 1.40% of cases had a laboratory confirmation. The epidemic period in 2010 comprised 48.68% of all the admitted cases during this period. Late admission was more likely among adults than children (pDengue guidelines in order to standardize the admission criteria and time across hospitals.

    Elevated plasma levels of factor VIII (FVIII) are associated with increased risk of deep venous thrombosis. The aim of this study is to elucidate how elevated FVIII levels affect venous thrombus formation and propagation in vivo. We examined rabbit plasma FVIII activity, plasma thrombin generation, whole blood coagulation, platelet aggregation and venous wall thrombogenicity before and one hour after an intravenous infusion of recombinant human FVIII (rFVIII). Venous thrombus induced by the endothelial denudation of rabbit jugular veins was histologically assessed. Thrombus propagation was evaluated as indocyanine green fluorescence intensity. Argatroban, a thrombin inhibitor, and neutralised antibodies for tissue factor (TF), factor XI (FXI), and von Willebrand factor (VWF) were infused before or after thrombus induction to investigate their effects on venous thrombus formation or propagation. Recombinant FVIII (100 IU/kg) increased rabbit plasma FVIII activity two-fold and significantly enhanced whole blood coagulation and total plasma thrombin generation, but did not affect initial thrombin generation time, platelet aggregation and venous wall thrombogenicity. The rFVIII infusion also increased the size of venous thrombus 1 hour after thrombus induction. Argatroban and the antibodies for TF, FXI or VWF inhibited such enhanced thrombus formation and all except TF suppressed thrombus propagation. In conclusion, elevated plasma FVIII levels enhance venous thrombus formation and propagation. Excess thrombin generation by FXI and VWF-mediated FVIII recruitment appear to contribute to the growth of FVIII-driven venous thrombus.

    Full Text Available Introduction. Despite its low incidence, acquired factor VIII inhibitor is the most common autoantibody affecting the clotting cascade. The exact mechanism of acquisition remains unclear, but postpartum patients, those with autoimmune conditions or malignancies, and those with exposure to particular drugs appear most susceptible. There have been several case reports describing acquired FVIII inhibitors in patients receiving interferon alpha for HCV treatment and in patients being treated for HIV. To our knowledge, this is the first case of a patient with HCV and HIV who was not actively receiving treatment for either condition. Case Presentation. A 57-year-old Caucasian male with a history of HIV and HCV was admitted to our hospital for a several day history of progressively worsening right thigh bruising and generalized weakness. CTA of the abdominal arteries revealed large bilateral retroperitoneal hematomas. Laboratory studies revealed the presence of a high titer FVIII inhibitor. Conclusion. Our case of a very rare condition highlights the importance of recognizing and understanding the diagnosis of acquired FVIII inhibitor. Laboratory research and clinical data on the role of newer agents are needed in order to better characterize disease pathogenesis, disease associations, genetic markers, and optimal disease management.

    A workshop organized by the European Medicines Agency and the European Directorate for the Quality of Medicines and HealthCare was held in London, UK on November 28-29, 2013, to provide an overview of the current knowledge of the characterization of new factor VIII (FVIII) and factor IX (FIX) concentrates with respect to potency assays and testing of postinfusion material. The objective was to set the basis for regulatory authorities' discussion on the most appropriate potency assay for the individual products, and European Pharmacopoeia (Ph. Eur.) discussion on whether to propose revision of the Ph. Eur. monographs with respect to potency assays in the light of information on new FVIII and FIX concentrates. The workshop showed that for all products valid assays vs. the international concentrate standards were obtained and potency could be expressed in International Units. The Ph. Eur. chromogenic potency assay gave valid assay results which correlate with in vivo functionality of rFVIII products. For some modified rFVIII products and all modified rFIX products, one-stage clotting assay methods result in different potencies depending on the activated partial thromboplastin time reagent. As a consequence, monitoring of patients' postinfusion levels is challenging but it was pointed out that manufacturers are responsible for providing the users with appropriate information for use and laboratory testing of their product. Strategies to avoid misleading determination of patents' plasma levels, e.g. information on suitable assays, laboratory standards or correction factors were discussed. © 2015 John Wiley & Sons Ltd.

    Combined factor V (FV) and factor VIII (FVIII) deficiency is a rare autosomal recessive bleeding disorder characterized by mild-to-moderate bleeding. Epistaxis, postsurgical bleeding and menorrhagia are the most common symptoms. The aim of this study is to report the phenotype-genotype characterization carried out in patients affected with combined FV and FVIII deficiency from Iran. A cross-sectional study was conducted in Shiraz Hemophilia Center, southern Iran. Twelve cases, seven men and five women coming from eight families were included in our study after taking consent form. Coagulation activity for all patients was measured. All exons and intron-exon junctions of lectin mannose binding protein 1 (LMAN1) gene and multiple coagulation factor deficiency 2 genes were amplified by PCR, and subsequently sequenced by the Sanger method. Patients[Combining Acute Accent] age ranged from 6 to 59 years mean ± SD: 23.8 ± 15.4 years and median: 22 years. No patient presented with severe bleeding symptom. Only one patient had severe FV and FVIII deficiency (both factor levels stop codon. Larger studies are needed to calculate the correlation between factor levels, genetic and bleeding symptoms.

    The effect of Si content on the intergranular corrosion resistance of SUS 309L stainless steels was investigated by 10 wt.% oxalic acid test, 65 wt.% boiling nitric acid test, double loop electrochemical potential reactivation (DLEPR) method, optical microscope (OM) and scanning electronic microscope (SEM). A maximum corrosion rate, weight loss of 2.80 g m -1 h, was obtained when SUS 309L stainless steel containing 0.73 wt.% Si was subjected to heat treatment at 800 deg. C for 1 h. It shows that the Cr depletion zone formed due to σ phase precipitation. The same result is obtained in DLEPR test and the ditch microstructure after oxalic test was found in samples that showed the minimum corrosion rate

    This review focuses only on specific studies into the SUS regionalization process, which were based on empirical results and published since 2006, when the SUS was already under the aegis of the Pact for Health framework. It was found that the regionalization process is now underway in all spheres of government, subject to a set of challenges common to the different realities of the country. These include, primarily, that committee-structured entities are valued as spaces for innovation, yet also strive to overcome the bureaucratic and clientelist political culture. Regional governance is further hampered by the fragmentation of the system and, in particular, by the historical deficiency in planning, from the local level to the strategic policies for technology incorporation. The analyses enabled the identification of a culture of broad privilege for political negotiation, to the detriment of planning, as one of the main factors responsible for a vicious circle that sustains technical deficiency in management.

    Sucrose synthase (SUS) catalyzes the UDP-dependent cleavage of sucrose into UDP-glucose and fructose and has become an important target for improving seed crops via metabolic engineering. A UDP-specific SUS homotetramer composed of 93-kDa subunits was purified to homogeneity from the triacylglyceride-rich endosperm of developing castor oil seeds (COS) and identified as RcSUS1 by mass spectrometry. RcSUS1 transcripts peaked during early development, whereas levels of SUS activity and immunoreactive 93-kDa SUS polypeptides maximized during mid-development, becoming undetectable in fully mature COS. The cytosolic location of the enzyme was established following transient expression of RcSUS1-enhanced YFP in tobacco suspension cells and fluorescence microscopy. Immunological studies using anti-phosphosite-specific antibodies revealed dynamic and high stoichiometric in vivo phosphorylation of RcSUS1 at its conserved Ser-11 residue during COS development. Incorporation of 32Pi from [γ-32P]ATP into a RcSUS1 peptide substrate, alongside a phosphosite-specific ELISA assay, established the presence of calcium-dependent RcSUS1 (Ser-11) kinase activity. Approximately 10% of RcSUS1 was associated with COS microsomal membranes and was hypophosphorylated relative to the remainder of RcSUS1 that partitioned into the soluble, cytosolic fraction. Elimination of sucrose supply caused by excision of intact pods of developing COS abolished RcSUS1 transcription while triggering the progressive dephosphorylation of RcSUS1 in planta. This did not influence the proportion of RcSUS1 associated with microsomal membranes but instead correlated with a subsequent marked decline in SUS activity and immunoreactive RcSUS1 polypeptides. Phosphorylation at Ser-11 appears to protect RcSUS1 from proteolysis, rather than influence its kinetic properties or partitioning between the soluble cytosol and microsomal membranes. PMID:25313400

    The behavior of martensitic transformation due to plastic deformation at room temperature was investigated in SUS304 austenitic stainless steels with the same nickel equivalent. The absolute volume of the martensitic phase was obtained by saturation magnetization. We discuss the shapes of the martensitic phase caused by different values of coercive force. Martensitic transformation depends on the applied stress but is independent of nickel content with same nickel equivalent. We investigated applications to nondestructive testing on the basis of the present study. (author)

C for up to 100 h was conducted. Optical microscopy reveals grain coarsening in both the alloys upon annealing. Observations by transmission electron microscopy revealed the precipitation of nanometer-sized spherical Cu particles distributed within the austenitic grains and the presence of carbides at the dislocations. Both the yield and ultimate tensile strengths of the alloys were found to remain invariant with annealing. Tensile ductility and the threshold stress intensity factor range for fatigue crack growth for 3 wt.% Cu added alloy increase with annealing. These are attributed to the grain coarsening with annealing. In all, the addition of Cu to SUS 304H does not affect the mechanical performance adversely while improving creep resistance.

    This paper describes a comprehensive effort to develop studies regarding Brazil's Unified Healthcare System (SUS), as a result of the combination of public services in a network that follows a region-based rationale (tripartite organization). The SUS emerges from such an integration and should be organized as such. The intention is to demonstrate that this type of organization is essential, given that Brazil is organized as a Federation, and all three governmental levels are, in a broad sense, equally responsible for healthcare. Healthcare services and actions are a complex set of activities that are interconnected on behalf of citizen health, which is a global concept that cannot be split up. Services must follow this rationale and be organized as such. Thus, healthcare services must be systematically organized to serve everyone equally, regardless of where a citizen lives. This systemic organization requires permanent interaction between federative units to discuss and operationalize reference services, funding and other technical and administrative aspects. These are the essential elements that make the SUS so complex and demand it be organized regionally, as a network of healthcare services.

    Full Text Available SUS440 is a high-carbon stainless steel, and its martensite matrix has high heat resistance, high corrosion resistance, and high pressure resistance. It has been widely used in mechanical parts and critical materials. However, the SUS440 martempered matrix has reliability problems in thin plate applications and thus research uses different austempering heat treatments (tempering temperature: 200 °C–400 °C to obtain a matrix containing bainite, retained austenite, martensite, and the M7C3 phase to investigate the relationships between the resulting microstructure and tensile mechanical properties. Experimental data showed that the austempering conditions of the specimen affected the volume fraction of phases and distribution of carbides. After austenitizing heat treatment (1080 °C for 30 min, the austempering of the SUS440 thin plates was carried out at a salt-bath temperature 300 °C for 120 min and water quenching was then used to obtain the bainite matrix with fine carbides, with the resulting material having a higher tensile fracture strength and average hardness (HRA 76 makes it suitable for use as a high-strength thin plate for industrial applications.

    Full Text Available Este debate discute questões relacionadas ao financiamento do Sistema Único de Saúde (SUS. Na primeira parte, Ruben de Mattos defende a criação de dispositivos para a elevação progressiva dos gastos públicos em saúde. Segundo o debatedor, o maior desafio do governo será viabilizar - e sustentar - um sistema que garanta, de fato, o acesso universal e igualitário. Mattos também destaca a importância dos repasses federais entre os níveis de governos, por vê-los como instrumentos capazes de reduzir as desigualdades entre as regiões e incentivar políticas que contribuam para a consolidação do SUS. Na segunda parte, Nilson do Rosário afirma que o ajuste fiscal da década de 1990, conseqüência da política de estabilização monetária, limitou a capacidade de financiamento governamental na atenção à saúde, gerando efeitos perversos devido à ampliação da desigualdade social. A seguir, explica como o setor saúde respondeu às exigências de ajuste macroeconômico nas despesas públicas através de estratégias substitutivas, contexto em que o Programa de Saúde da Família (PSF se expandiu rapidamente, tornando-se estratégico na agenda da ampliação da atenção ambulatorial básica do país.This work discusses some of the issues related to the funding of the Brazilian National Health Service (SUS.

  13. The 1.7 Å X-ray crystal structure of the porcine factor VIII C2 domain and binding analysis to anti-human C2 domain antibodies and phospholipid surfaces.

    Directory of Open Access Journals (Sweden)

    Caileen M Brison

    Full Text Available The factor VIII C2 domain is essential for binding to activated platelet surfaces as well as the cofactor activity of factor VIII in blood coagulation. Inhibitory antibodies against the C2 domain commonly develop following factor VIII replacement therapy for hemophilia A patients, or they may spontaneously arise in cases of acquired hemophilia. Porcine factor VIII is an effective therapeutic for hemophilia patients with inhibitor due to its low cross-reactivity; however, the molecular basis for this behavior is poorly understood. In this study, the X-ray crystal structure of the porcine factor VIII C2 domain was determined, and superposition of the human and porcine C2 domains demonstrates that most surface-exposed differences cluster on the face harboring the "non-classical" antibody epitopes. Furthermore, antibody-binding results illustrate that the "classical" 3E6 antibody can bind both the human and porcine C2 domains, although the inhibitory titer to human factor VIII is 41 Bethesda Units (BU/mg IgG versus 0.8 BU/mg IgG to porcine factor VIII, while the non-classical G99 antibody does not bind to the porcine C2 domain nor inhibit porcine factor VIII activity. Further structural analysis of differences between the electrostatic surface potentials suggest that the C2 domain binds to the negatively charged phospholipid surfaces of activated platelets primarily through the 3E6 epitope region. In contrast, the G99 face, which contains residue 2227, should be distal to the membrane surface. Phospholipid binding assays indicate that both porcine and human factor VIII C2 domains bind with comparable affinities, and the human K2227A and K2227E mutants bind to phospholipid surfaces with similar affinities as well. Lastly, the G99 IgG bound to PS-immobilized factor VIII C2 domain with an apparent dissociation constant of 15.5 nM, whereas 3E6 antibody binding to PS-bound C2 domain was not observed.

    Full Text Available Diatom, hydrocarbons and fatty acid sedimentary records were used for reconstructing the recent (last 150 years palaeolimnological history of Laguna Chica of San Pedro (Concepción, VIII Región, Chile. Cluster analyses (Constrained Incremental Sum of Squares on the diatom data revealed three distinct periods. The first period (1883-1940's showed a pronounced increase in sedimentation rate and a slight increase in organic matter accumulation. In this period, eutrophic species (Aulacoseira granulata and Staurosira construens became increasingly dominant. From the 1940s until the 1970s the diatom signal is more equivocal: after the initial decrease in the relative abundance of A. granulata and S. construens their numbers fluctuate without a clear pattern. Sedimentation rates strongly fluctuate in this period. From 1978 onwards eutrophic species are in decline while indicators of oligotrophic conditions, such as Cyclotella stelligera and Aulacoseira distans, become more abundant. This shift in the lake trophic status could not be attributed to a reduction in the nutrient load from the catchment and we hypothesize that the invasion of the lake by the submersed macrophyte Egeria densa has altered nutrient availability to the plankton communities. This is in agreement with the hydrocarbons and fatty acid analyses which demonstrate a shift in carbon number distributions from short chain alkanes and alkanoic acids (typical for microalgae to long chain molecules (characteristic for higher plants in the upper layers of the lake sedimentSe realizó la reconstrucción histórica de los últimos 150 años de Laguna Chica de San Pedro (Concepción, VIII Región, Chile, a través de la utilización de los restos de diatomeas, hidrocarburos y ácidos grasos contenidos en la columna de sedimento.

    The corrosion characteristics of SUS321 for pressure vessel of SMART in pure water, ammonia aqueous solutions of pH 8.5 ∼ 11.5 at 300 .deg. C were evaluated by using static autoclaves. SUS321 specimen in the high temperature ammonia aqueous solution has weight gain or loss by the 4 reactions. And it depends on the refreshing period of the aqueous solution. So additional experiments by recirculating loop system were required to evaluate the corrosion behaviour of SUS321 in the ammonia aqueous solution

    The Factor VIII (F8) gene, which is defective in hemophilia A, is located in the most telomeric megabase of Xq. Inversions due to intrachromosomal homologous recombination between mispaired copies of gene A located within intron 22 of the gene and about 500 kb telomeric to it account for nearly half of the cases of severe hemophilia A. We hypothesized that pairing of Xq with its homolog inhibits the inversion process, and that therefore the event originates predominantly in male germ cells. In all 21 informative cases in which the inversion originated in a maternal grandparent, DNA polymorphism analysis using markers within or very closely linked to F8, determined that it occurred in the male germline. In addition, all but one of 56 mothers of sporadic cases due to inversions were carriers. The data indicate that the F8 gene inversions leading to severe hemophilia A occur almost exclusively in male germ cells. The mean age of maternal grandfathers at the birth of their carrier daughters was 29.9 years (13 cases), i.e. not different from the mean paternal age in the general population, supporting the hypothesis that the inversions occur in meiosis. The inversions can be diagnosed by Southern blot analysis. For more rapid diagnosis we have used RT-PCR of RNA ectopically expressed in blood. Oligonucleotides were used to PCR amplify, after the initial RT reaction of RNA samples using random hexamers, either the normal transcript (F8 exons 21 to 24;312 bp product) or the novel abnormal transcript that is generated after the inversion. Both type 1 and 2 inversions can be recognized in affecteds and carriers by the presence of the diagnostic PcR product of 248 bp. Correct diagnoses were made in samples from 6 patients and 2 carriers with type 1 inversions, 2 patients and 2 carriers with type 2 inversions and 5 normal controls.

    The authors report studies of a female with severe hemophilia A resulting from a complex de novo translocation of chromosomes X and 17 (46,X,t(X; 17)). Somatic cell hybrids containing the normal X, the der(X), or the der(17) were analyzed for coagulation factor VIII (F8C) sequences using Southern blots and polymerase chain reaction. The normal X, always late replicating, contains a normal F8C gene, whereas the der(X) has no F8C sequences. The der(17) chromosome containing Xq24-Xq28 carries a functional G6PD locus and a deleted F8C allele that lacks exons 1--15. Also, it lacks the DXYS64-X locus, situated between the F8C locus and the Xq telomere. These results indicate that a cryptic breakpoint within Xq28 deleted the 5[prime] end of F8C, but left the more proximal G6PD locus intact on the der(17)chromosome. As the deleted segment includes the 5[prime] half of F8C as well as the subtelomeric DXYS64 locus, F8C must be oriented on the chromosome with its 5[prime] region closest to the telomere. Therefore, the order of these loci is Xcen-G6PD-3[prime]F8C-5[prime]F8C-DXYS64-Xqtel. The analysis of somatic cell hybrids has elucidated the true nature of the F8C mutation in the pro-band, revealing a more complex rearrangement (three chromosomes involved) than that expected from cytogenetic analysis, chromosome painting, and Southern blots. A 900-kb segment within Xq28 has been translocated to another autosome. Hemophilia A in this heterozygous female is due to the decapitation of the F8C gene on the der(17) and inactivation of the intact allele on the normal X. 27 refs., 5 figs., 1 tab.

This work analyzes about the use of social media that have an impact on the moral education of children. The data collected in this study through the work of other literature, researchers also interviewed principals and students as many as 16 students as well as the observation at the school. Based on the analysis that has been done it can be seen the positive and negative impacts of the use of social media to the moral education of children. The positive impact on the social development of the media on moral education of children among children can adapt, socialize with the public and manage a network of friends, and make children easier to accomplish these tasks, while the negative impact of the development of social media to the moral education of children very much of them can make the omission in children so that children are less disciplined and be lazy, makes children easy to cheat the works of others, disrespectful both in dress and speech, often quarrel due to scenes that are as dangerous as scenes of pornography, violence, wars and so forth , as well as making children miss school because they feel more comfortable in the cafe of the study at the school, not only that social media also makes children spend pocket money a child so that the child took the money her parents secretly to access the internet cafe. Therefore, social media can lead education of children.

    ESSENTIALS: Combined factor V (FV) and factor VIII (FVIII) deficiency (CF5F8D) is an autosomal recessive coagulation disorder. Desmopressin acetate (DDAVP) was intravenously infused in 20 adult patients with CF5F8D. DDAVP can enhance FVIII levels but has no effect on FV levels in patients with CF5F8D. DDAVP can be substituted for FVIII concentrates in patients with CF5F8D. Combined factor V (FV) and FVIII deficiency (CF5F8D) is a rare inherited autosomal recessive double-gene disorder most frequently seen in the Middle East. Although affected individuals have deficiency of two coagulation factors (range 5-30%), their bleeding tendencies are similar to patients who have deficiency of a single coagulation factor at the same level. The mainstay of their treatment is infusion of FVIII concentrate and fresh frozen plasma. Here, the effect of intravenous infusion of desmopressin acetate (DDAVP) on elevation of coagulation FV and FVIII was investigated through a clinical trial in May 2015. In a registered controlled trial, DDAVP (dosage 0.3 μg kg(-1) ) was intravenously infused into 20 adult patients with CF5F8D over 20 min. After an hour, blood samples were collected and plasma levels of FV and FVIII were measured. This study revealed that DDAVP can enhance FVIII levels but has no effect on FV plasma concentration in patients with CF5F8D. Based on these findings, FVIII concentrates may be substituted for DDAVP in patients with CF5F8D. © 2015 International Society on Thrombosis and Haemostasis.

    In order to investigate the tumor affinity of the radioisotopes, iron(Fe-59), cobalt(Co-58), ruthenium(Ru-103), palladium(Pd-103), osmium(Os-185+191) and iridium(Ir-192), the elements of group VIII in the periodic table were examined, using rats which were subcutaneously transplanted with Yoshida sarcoma. Six preparations, 59 Fe-chloride, 58 Co-chloride, 103 Ru-chloride, 103 Pd-chloride, 185+191 Os-hexachlorosmic acid and 192 Ir-hexachloriridic acid were injected intravenously in to each group of tumor bearing rats. These rats were sacrificed at various periods after injection of each preparation: 3 hours, 24 hours and 48 hours in all preparations, except 59 Fe-chloride with 30 minutes, 3 hours, 24 hours and 48 hours. The radioactivities of the tumor, blood muscle, liver, kidney and spleen were measured by a well-type scintillation counter, and retention values (in every tissue including the tumor were calculated in percent of administered dose per g-tissue weight). 185+191 Os-hexachlorosmic acid had a considerably strong affinity for the malignant tumor. 59 Fe-chloride, 58 Co-chloride, 103 Ru-chloride, 103 Pd-chloride and 192 Ir-hexachloriridic acid did not have any affinity for the malignant tumor. However 59 Fe-chloride had a very strong affinity for blood corpuscles. 103 Pd-chloride had a fairly strong affinity for the kidney and liver, 58 Co-chloride had a fairly affinity for the liver, 103 Ru-chloride, 185+191 Os-hexachlorosmic acid and 192 Ir-hexachloriridic acid had a fairly strong affinity for the kidney.

    Several studies have demonstrated that non-O blood groups subjects present an increased VTE risk as compared to those carrying O blood group. The aim of this study was to investigate the ABO blood groups influence on factor VIII (FVIII) activity, von Willebrand factor (VWF), and ADAMTS13 plasma levels in patients undergoing hemodialysis (HD). Patients undergoing HD (N=195) and 80 healthy subjects (control group) were eligible for this cross-sectional study. The ABO blood group phenotyping was performed by the reverse technique. FVIII activity was measured through coagulometric method, and VWF and ADAMTS13 antigens were assessed by ELISA. FVIII activity and VWF levels were significantly higher and ADAMTS13 levels was decreased in HD patients, as compared to healthy subjects (P blood groups showed a significant increase in FVIII activity (P = 0.001) and VWF levels (P blood group. However, no significant difference was observed in ADAMTS13 levels (P = 0.767). In the control group, increased in FVIII activity (P = 0.001) and VWF levels (P = 0.002) and decreased in ADAMTS13 levels (P = 0.005) were observed in subjects carrying non-O blood groups as compared to carriers of O blood group.Our data confirmed that ABO blood group is an important risk factor for increased procoagulant factors in plasma, as FVIII and VWF. Admitting the possible role of kidneys in ADAMTS13 synthesis or on its metabolism, HD patients were not able to increase ADAMTS13 levels in order to compensate the increase of VWF levels mediated by ABO blood groups. Considering that non-O blood groups constitute a risk factor for thrombosis, it is reasonable to admit that A, B and AB HD patients need a careful and continuous follow-up in order to minimize thrombotic events.

    Coagulative and fibrinolytic disorders appear to be associated with the development of lung cancer. The aim of the present study was to determine plasma levels of von Willebrand factor (VWF) and a disintegrin and metalloproteinase with a thrombospondin type 1 motif 13 (ADAMTS-13), and factor VIII (FVIII) activity, in association with O and non-O blood groups in patients with lung cancer. Plasma levels of VWF and ADAMTS-13, and FVIII activity were measured in 115 patients with lung cancer and 98 healthy subjects. Phenotyping of the ABO blood groups was also performed for the two groups. Significantly increased VWF levels and FVIII activity, as well as significantly decreased ADAMTS-13 levels, were observed in patients with distant metastasis as compared with those without distant metastasis and the healthy controls. Plasma VWF levels and FVIII activity were significantly increased in subjects with non-O type blood compared with those with type O blood in the two groups. However, a significant decrease in ADAMTS-13 levels was observed only in the control group among those with non-O type blood, compared with those with type O blood. The results of the present study indicate that increased VWF and decreased ADAMTS-13 levels facilitate the invasiveness and metastasis of lung cancer. Non-O blood groups constitute a risk factor for increased VWF and FVIII in plasma. Continued monitoring of VWF and ADAMTS-13 levels, and of FVIII activity in patients with lung cancer with distinct blood groups may help to minimize the incidence of thrombotic events and improve assessment of disease progression.

  5. Storage of factor VIII variants with impaired von Willebrand factor binding in Weibel-Palade bodies in endothelial cells.

    Maartje van den Biggelaar

    Full Text Available BACKGROUND: Point mutations resulting in reduced factor VIII (FVIII binding to von Willebrand factor (VWF are an important cause of mild/moderate hemophilia A. Treatment includes desmopressin infusion, which concomitantly increases VWF and FVIII plasma levels, apparently from storage pools containing both proteins. The source of these VWF/FVIII co-storage pools and the mechanism of granule biogenesis are not fully understood. METHODOLOGY/PRINCIPAL FINDINGS: We studied intracellular trafficking of FVIII variants implicated in mild/moderate hemophilia A together with VWF in HEK293 cells and primary endothelial cells. The role of VWF binding was addressed using FVIII variants displaying reduced VWF interaction. Binding studies using purified FVIII proteins revealed moderate (Arg2150His, Del2201, Pro2300Ser to severe (Tyr1680Phe, Ser2119Tyr VWF binding defects. Expression studies in HEK293 cells and primary endothelial cells revealed that all FVIII variants were present within VWF-containing organelles. Quantitative studies showed that the relative amount of FVIII storage was independent of various mutations. Substantial amounts of FVIII variants are co-stored in VWF-containing storage organelles, presumably by virtue of their ability to interact with VWF at low pH. CONCLUSIONS: Our data suggest that the potential of FVIII co-storage with VWF is not affected in mild/moderate hemophilia A caused by reduced FVIII/VWF interaction in the circulation. These data support the hypothesis that Weibel-Palade bodies comprise the desmopressin-releasable FVIII storage pool in vivo.

  6. Transient B cell depletion or improved transgene expression by codon optimization promote tolerance to factor VIII in gene therapy.

    Directory of Open Access Journals (Sweden)

    Brandon K Sack

    Full Text Available The major complication in the treatment of hemophilia A is the development of neutralizing antibodies (inhibitors against factor VIII (FVIII. The current method for eradicating inhibitors, termed immune tolerance induction (ITI, is costly and protracted. Clinical protocols that prevent rather than treat inhibitors are not yet established. Liver-directed gene therapy hopes to achieve long-term correction of the disease while also inducing immune tolerance. We sought to investigate the use of adeno-associated viral (serotype 8 gene transfer to induce tolerance to human B domain deleted FVIII in hemophilia A mice. We administered an AAV8 vector with either human B domain deleted FVIII or a codon-optimized transgene, both under a liver-specific promoter to two strains of hemophilia A mice. Protein therapy or gene therapy was given either alone or in conjunction with anti-CD20 antibody-mediated B cell depletion. Gene therapy with a low-expressing vector resulted in sustained near-therapeutic expression. However, supplementary protein therapy revealed that gene transfer had sensitized mice to hFVIII in a high-responder strain but not in mice of a low-responding strain. This heightened response was ameliorated when gene therapy was delivered with anti-murine CD20 treatment. Transient B cell depletion prevented inhibitor formation in protein therapy, but failed to achieve a sustained hypo-responsiveness. Importantly, use of a codon-optimized hFVIII transgene resulted in sustained therapeutic expression and tolerance without a need for B cell depletion. Therefore, anti-CD20 may be beneficial in preventing vector-induced immune priming to FVIII, but higher levels of liver-restricted expression are preferred for tolerance.

    This study sought to develop methodology for the construction of a Panel for the Monitoring and Evaluation of Management of the Unified Health System (SUS). The participative process used in addition to the systematization conducted made it possible to identify an effective strategy for building management tools in partnership with researchers, academic institutions and managers of the SUS. The final systematization of the Panel selected indicators for the management of the SUS in terms of Demand, Inputs, Processes, Outputs and Outcomes in order to provide a simple, versatile and useful tool for evaluation at any level of management and more transparent and easier communication with all stakeholders in decision-making. Taking the management of the SUS as the scope of these processes and practices in all normative aspects enabled dialog between systemic theories and those which consider the centrality of the social actor in the decision-making process.

Es un estudio cualitativo que empleó como método los grupos de discusión con cinco madres de cuatro niñas y un niño, menores de 10 años, víctimas de abuso sexual, quienes asistían a consulta psicológica en dos centros de atención a la familia de la ciudad de Medellín, en el año 2005. Las voces de estas mujeres muestran que el abuso sexual sucede en familias vulnerables desde el punto de vista afectivo, comunicativo y socioeconómico, en las cuales este problema hace parte de su cotidianidad. El abuso sexual constituye una catástrofe que afecta el precario equilibrio socioeconómico y afectivo que estas familias logran construir para hacer frente a sus condiciones de vida angustiantes. En medio de la estigmatización que la sociedad hace de la situación, del silencio, con el cual soportan el trauma, y de un apoyo poco comprensivo y pertinente por parte de las instituciones encargadas de la atención de estas familias, las madres acometen diferentes acciones para hacer frente a su realidad. La reconfiguración de su rol como madres se convierte en un punto de partida clave para la superación del estado de impotencia en el cual quedan sumidas, posterior al abuso sexual de sus hijas(os.

  13. The precipitation behavior of titanium carbide on the surface of SUS 321 stainless steel

    1982-01-01

    The surface composition of SUS 321 stainless steel at high temperatures was observed in vacuum with Auger electron spectroscopy. The precipitation of titanium carbide was found on the surface of SUS 321. The thickness of precipitated titanium carbide layer increased in proportion to the square root of annealing time and became about 0.05 μm after heated at 1100 K for 432 ks. The precipitated titanium carbide was not replaced by the most surface active element sulfur, and remained stable on the surface. The precipitated layer, however, was not even and had many holes about 1 μm in diameter. The bottom of a hole was SUS 321, on which phosphorus, oxygen and sulfur segregated. As the annealing time was prolonged, these segregants were replaced one by one in the order of the surface activity, and finally the most surface active element, sulfur, remained on the bottom of the hole. Moreover, sulfur diffused over the outside of the hole. The precipitation of titanium carbide on the surface occurred according to the following processes: (1) The titanium and carbon which had been dissolved in the bulk diffused onto the surface of the stainless steel. (2) The titanium carbide which had been precipitated in the bulk dissolved because the concentration of titanum and carbon fell under their solubility limits in the bulk. (3) The titanium and carbon diffused onto the surface which was exposed to vacuum. (4) The titanium and carbon recombined into titanium carbide and precipitated on the surface. The growth rate of the thickness of the precipitated layer was controlled by the diffusion of titanium and carbon in the precipitated titanium carbide. (J.P.N.)

Advogam os autores a necessidade de respostas jurídico-administrativas para um SUS de caráter interfederativo tanto na sua gestão, que exige compartilhamentos, quanto no seu financiamento, que se mantém interdependente também. Concluem que o único caminho para o SUS ser nacional, é regionalizá-lo e dotar a região de saúde de todo o instrumental necessário à gestão compartilhada, interfederativa e responsável.

  16. Adolescentes consumidores de televisión: autopercepciones sobre sus derechos

    Directory of Open Access Journals (Sweden)

    María Ángeles Espinosa Bayal

    2014-07-01

    Full Text Available El artículo analiza la percepción que tiene una muestra representativa de la población española de entre 12 y 18 años sobre la protección de sus derechos en las cadenas de televisión. Para conseguir este objetivo, se aplicó un cuestionario de 59 preguntas diseñado para una investigación más amplia en la que se analizaba la opinión de los menores sobre la protección de sus derechos en la televisión y en Internet. Ninguna pregunta del cuestionario se refería a cadenas o programas concretos identificados por los investigadores y la información sobre estos partía de la propia opinión de los adolescentes. Los resultados que se presentan se refieren a los datos sobre televisión y, más concretamente, al respeto por los derechos fundamentales de los telespectadores en general, y de los de los menores en particular. De estos resultados se concluye que los adolescentes perciben claramente la vulneración de los derechos de igualdad, dignidad e intimidad, a la información objetiva veraz y plural y a la libre expresión y opinión –especialmente cuando ésta se refiere a los niños–. Igualmente muestran una postura crítica y de rechazo hacia los tipos de programas que no respetan sus derechos. Se propone utilizar esta capacidad crítica de los telespectadores desde una doble perspectiva: por una parte para crear escuela de ciudadanía y, por otra, para generar una sociedad más justa y equitativa.

    Full Text Available La inseguridad laboral se ha convertido en la actualidad en una de las fuentes de estrés más significativas para muchos trabajadores, siendo especialmente grave en España por las elevadas tasas de desempleo en este periodo de crisis económica. Una prolífera investigación se ha desarrollado al respecto en un intento por alcanzar un conocimiento más completo de este fenómeno. El Instituto de Psicología de los Recursos Humanos, Desarrollo Organizacional y Calidad de Vida Laboral (IDOCAL ha contribuido a esta investigación en los últimos años en varias de sus facetas más significativas. En el ámbito de sus factores determinantes se ha identificado un papel significativo de la antigüedad laboral, la empleabilidad en el mercado laboral, el subempleo, y la autoeficacia laboral. Además se han realizado hallazgos de interés en relación con la diversidad de los tipos de contrato, la inseguridad laboral y sus efectos en los trabajadores. Son de especial interés los estudios que analizan el papel interviniente de distintas variables. En este contexto, nuestros estudios han puesto de manifiesto la relevancia de variables como la justicia organizacional, el clima de justicia organizacional, el apoyo organizacional, la empleabilidad, la dependencia laboral y el distanciamiento psicológico a la hora de predecir la variabilidad en la inseguridad laboral. Por último, las aportaciones del IDOCAL han sido especialmente relevantes al plantear el análisis de la inseguridad laboral como fenómeno colectivo y mostrar cómo la experiencia colectiva de la inseguridad tenía repercusiones sobre el bienestar de los trabajadores más allá de las producidas por sus percepciones individuales. En base a esta investigación se han propuesto en el presente artículo una serie de implicaciones para la práctica profesional.

    Gupta, Sandeep Kumar; Kumar, Ajit; Hussain, Syed Ainul; Vipin; Singh, Lalji

    2013-06-01

    The Indian wild pig (Sus scrofa cristatus) is a protected species and listed in the Indian Wildlife (Protection) Act, 1972. The wild pig is often hunted illegally and sold in market as meat warranting punishment under law. To avoid confusion in identification of these two subspecies during wildlife forensic examinations, we describe genetic differentiation of Indian wild and domestic pigs using a molecular technique. Analysis of sequence generated from the partial fragment (421bp) of mitochondrial DNA (mtDNA) cytochrome b (Cyt b) gene exhibited unambiguous (>3%) genetic variation between Indian wild and domestic pigs. We observed nine forensically informative nucleotide sequence (FINS) variations between Indian wild and domestic pigs. The overall genetic variation described in this study is helpful in forensic identification of the biological samples of wild and domestic pigs. It also helped in differentiating the Indian wild pig from other wild pig races. This study indicates that domestic pigs in India are not descendent of the Indian wild pig, however; they are closer to the other wild pig races found in Asia and Europe.

    Full Text Available Este artigo analisa o grau de progressividade dos tributos que financiam o Sistema Único de Saúde (SUS. Nele são identificados os principais tributos que financiam o SUS e, com base nos microdados da Pesquisa de Orçamentos Familiares 2002-2003, é inferida a distribuição do ônus do pagamento dos tributos diretos e indiretos que financiam o SUS e analisado o grau de progressividade dos mesmos. Foi, ainda, calculado o índice de Kakwani do financiamento do SUS, que sintetiza o grau de progressividade de um sistema tributário. Os dados mostraram que o índice de Kakwani do financiamento público é de ­0,008 e que, portanto, o financiamento do SUS corresponde a um sistema quase proporcional, que onera proporcionalmente à renda. Em uma sociedade com o grau de desigualdade da brasileira, que exibe um índice de Gini de 0,57, ter um financiamento do SUS proporcional é fortemente questionável sob a ótica da justiça social: ao contrário, seria desejável construir bases de financiamento do SUS francamente progressivas, de forma a contra-restar a fortíssima concentração de renda da nossa sociedade.This article analyzes the level of progressivity in taxes financing the Brazilian Unified National Health System (SUS. Distribution of the tax burden financing the SUS was calculated using micro-data from the Household Budgets Survey, 2002-2003. The Kakwani index, which shows a tax system's level of progressivity, was calculated. The Kakwani index of public financing was -0.008, and SUS financing was nearly proportional to income. From a social justice perspective this is highly undesirable in a society like Brazil, with a Gini index of 0.57. The system should be clearly progressive in order to counterbalance the country's extreme income concentration.

    Full Text Available RACIONAL: No câncer gástrico, a incidência, o diagnóstico e as opções terapêuticas apresentaram melhorias nas últimas décadas, porém o prognóstico permanece reservado, especialmente devido à maioria dos pacientes procurarem recurso médico com tumores avançados, metastáticos ou cirurgicamente irressecáveis já no diagnóstico. Biologia molecular é área de conhecimento recente com grandes questionamentos a serem respondidos e a atualidade dos fatos científicos mostra que o caminho deverá ser através da identificação de marcadores tumorais. Os grandes avanços na área da informática aprimoraram a análise da imagem celular através da citofotometria de imagem que possibilita através da imunoistoquímica estudar a proliferação celular e a angiogênese que participa em diversos processos tumorais, sendo pesquisadas por vários marcadores. Atualmente estudos são realizados para demonstrar o valor prognóstico de suas expressões, contudo, no adenocarcinoma gástrico resultados têm sido divergentes e estudos escassos. OBJETIVOS: Identificar e quantificar citofotometricamente a expressão dos marcadores da angiogênese através do fator VIII no adenocarcinoma e comparar suas expressões com fa classificação de Bormann, profundidade de invasão tumoral, grau de diferenciação, envolvimento nodal, padrão histológico e idade. MÉTODOS: Foram estudados 21 pacientes com adenocarcinoma gástrico, identificados de 1998 a 2006. Para a detecção do Fator VIII foi realizada imunoistoquímica, com anticorpo policlonal para Fator VIII. Foi realizada análise citofotométrica informatizada pelo sistema SAMBA 4000.

    This thesis aims to characterize and to quantify the chemical equilibria involved in d-elements liquid-liquid extraction systems, especially elements belonging to the VIII group (Fe, Ni, Co, Ru, Rh, Pd, Pt). These systems are composed of synergic combination of aromatic polyimines and micellar cationic exchangers. Substitutions are first performed in aqueous acidic media by aromatic polyimines; then extractions are operated using micellic canionic exchangers. Chemical equilibria, selectivity effects, especially those due to ion-pair formations, kinetics, extractant behaviour are analysed and quantified [fr

O artigo buscou identificar a relação entre cobertura da Estratégia de Saúde da Família e o aumento de ações judiciais de insulinas análogas nas regiões Sul e Nordeste do Brasil. Nos anos 2010, 2011 e 2012, o consumo de insulinas análogas foi crescente tanto na região sul quanto nordeste. A região sul, apesar de ter um SUS organizado, IDH desenvolvido e educação estruturada, apresentou falhas no programa de diabetes. Em contrapartida, a região nordeste possui IDH baixo na maioria dos municípios e educação deficiente, porém, observou-se a necessidade de reorganização dos programas voltados ao atendimento de usuários portadores de doenças crônicas, em especial, a diabetes, nessa região. Entende-se, que o fortalecimento da atenção básica como porta de entrada para o SUS, nas regiões estudadas pode minimizar o problema da judicialização da saúde.

    1981-01-01

    Considerable amount of scale is produced by high temperature steam on the austenitic stainless steel tubes used for the superheaters and reheaters of large boilers for power generation. The scale of outer layer separates off due to the thermal stress at the time of starting-up and stopping, and causes the blocking of pipes and the erosion of turbine blades. Following the increase of nuclear power generation, large boilers are used for medium load, accordingly it is expected that the troubles like these increase. In this paper, the manufacturing method and the properties of SUS 321 HTB with fine grain internal surface are reported, which was developed to reduce the rate of growth of scale and to prevent the separation of scale. In order to prevent the separation of scale from austenitic stainless steel tubes, the reduction of scale thickness, surface treatment such as chrome plating, the use of alloys with excellent oxidation resistance, the formation of chrome-rich film rapidly, the heat treatment of cold-worked tubes and so on were carried out. The nitrification of SUS 321 H steel brought about two-phase structure of the fine grain internal surface with excellent oxidation resistance and the rest of coarse grains with high creep strength.

    This paper deals with the challenges involved in institutionalizing Monitoring and Evaluation practices within the scope of management of the Brazilian Unified Health System (SUS), based on the creation of a strategic agenda. This is structured around actions by the Federal Administration, from the perspective of defining the scope of the federative relationship. A summarized literature review is thus presented, placing into context the current SUS management process, which is based on the Pact for Health as well as theoretical and operational aspects inherent to monitoring and evaluation practices. The approach related to the strategic agenda highlights the creation of mechanisms that underpin the political and institutional decision, namely the creation of financial incentives and the development of technical mechanisms. These include organizational strategies for qualifying management teams and conducting studies and research and the dissemination of strategic information. These processes are based on the concept of providing for the management specificities in the different spheres of management based on a broad cooperation process involving teaching and research institutions and international organizations as well as the managers themselves.

Desde que se cortó esta palanca sobre la oferta crediticia, el banco central ha dependido de las operaciones de mercado abierto para lograr solamente un objetivo: influir sobre la demanda de crédito cambiando la tasa de referencia de corto plazo. La desequilibrada caja de herramientas contribuyó a un sesgo procíclico en los resultados de sus políticas que reflejó y exacerbó el sesgo procíclico del sistema financiero.

    Full Text Available Pretendemos establecer una relación entre la propuesta que hace Axel Honneth sobre el reconocimiento en el amor y las prácticas de crianza vividas por los integrantes de la familia, en especial entre los niños y las personas cuidadoras, para argumentar que en estas relaciones se da comienzo a la configuración de los niños como sujetos políticos. Para Honneth –quien retoma a Hegel y a Mead–, las primeras relaciones amorosas son sustanciales para vivir el reconocimiento afectivo –que se vive con los más íntimos–; en ellas la aceptación emocional va unida a sentimientos como la simpatía y la atracción, y les permite visibilizar al otro a partir de sus necesidades propias y su valor humano. Abordaremos la familia como primera estructura de acogida y primer escenario de socialización, para argumentar que los niños viven en sus familias, prácticas de reconocimiento de sí mismos, de los otros y del mundo que les rodea, lo cual, a nuestro modo de ver, hace parte de su proceso de socialización como sujetos políticos.

    SUS 304 austenitic stainless steel causes the magnetic transition at 60 K, and the Young's modulus lowers. In addition, its composition elements have the large (n,α) reaction cross section to high energy neutrons, and helium is apt to be generated, and this is a factor that lowers the material strength. In the He-irradiated parts in austenitic stainless steel, the precursory state of martensite transformation should exist, and its effect is considered to be observable by carrying out low temperature Moessbauer spectroscopy. As to the preparation of He-irradiation samples, the SUS 304 foils used and the irradiation conditions are described. The measurement of low temperature Moessbauer spectra for the samples without irradiation and with irradiation is reported. In order to determine the magnetic transition point, the thermal scanning measurement was carried out for the samples without or with irradiation. The martensite transformation was measured by X-ray diffraction and transmission type Moessbauer spectroscopy. In order to observe the state of the sample surfaces, the measurement by internal conversion electron Moessbauer spectroscopy was performed. These results and the temperature dependence of the Moessbauer spectra for the irradiated parts are reported. (K.I.)

The martensite transformation was measured by X-ray diffraction and transmission type Moessbauer spectroscopy. In order to observe the state of the sample surfaces, the measurement by internal conversion electron Moessbauer spectroscopy was performed. These results and the temperature dependence of the Moessbauer spectra for the irradiated parts are reported. (K.I.)

    We investigated martensitic transformation behaviour in sensitized SUS304 austenitic stainless steel to determine the stability of the austenitic phase at low temperatures. We found that a specimen that was sensitized at 973 K for 100 h exhibits an isothermal martensitic transformation when the specimen is held in the temperature range between 60 and 260 K. We constructed a time-temperature-transformation (TTT) diagram corresponding to the formation of 0.5 vol. % α'-martensite. A magnetization measurement was used to evaluate the volume fraction of a'-martensite. The TTT diagram shows a double-C curve with two noses located at about 100 and 200 K. In-situ optical microscope observations reveal that the double C-curve is due to two different transformation sequences. That is, the upper part of the C-curve is due to a direct γ → α' martensitic transformation and the lower part of the C-curve is due to a successive γ → ψ → α' martensitic transformation. The direct γ → α' transformation occurs in the vicinity of grain boundaries while the successive γ → ψ' → α' transformation occurs near the centre of grains. A scanning electron microscope observation reveals that carbide particles of M 23 C 6 are formed in the grain boundaries. The concentration difference between the centre of the grains and regions near grain boundaries is the reason for the difference in the isothermal transformation sequence for the sensitized SUS304 stainless steel.

One of the participants was Michel Leiris, a young poet who had just severed his relations with the surrealist avantgarde and was in the throes of a personal crisis. This paper is about his experience in that joumey of discovery of himself, of the other and of ethnography. Representation and margination: these are the themes that will endure in L'Afrique fantôme as well as in Leiris' other writings about the Dogon and the Zar cult.

    Full Text Available The Uni ed Health System (SUS constitutes a large technological system wi- thin the Brazilian territory since it aggregates a broad and diverse materiality in organizing and managing its ows. Additionally, it has two other attributes that make it unique: high sensibility to speci cities of different places; and technical and political centralization and decentralization of its actions. The macro dimen- sion is the SUS, leading it to be understood not simply as a health system, through its: multidimensionality – elements of other life instances (social, economic, cul- tural and political; broad and unequal spectrum of actors (state and non-state who move it and the meanings of its actions; and the trans-scaleness of its con- cretion in places (local, national and international nexuses. As an infrastructure of everyday life, it is a hegemonic large technological system that acts upon objec- tive (technosphere and subjective (psychosphere conditions of existence, a con- ception that has important implications for health policy and territory integration.

Había asistido a «una conferencia sobre Filosofía de una serie tendiente a mostrar la diferencia entre la Psicología y la Lógica, que las da Ortega, y levanta el ánimo ver la cantidad y la calidad de los oyentes». No parece imposible que Unamuno hubiese escuchado parte del curso público de quince lecciones de psicología, dadas por Ortega en el otoño de 1915 y en el invierno de 1916. Curso cuyo texto incompleto había de salir publicado en 1982 con el título que le puso Paulino Garagorri, Investigaciones psicológicas. Garagorri reconocía la importancia del curso para aclarar la evolución filosófica de Ortega, pues en sus lecciones anunció su «superación del idealismo o subjetivismo». No sospechaba Garagorri, sin embargo, que el curso había de esclarecer además lo que entendía Ortega por el concepto de «superación ». Hasta ahora, la imposibilidad de saberlo ha hecho inciertas las relaciones de Ortega con sus fuentes idealistas.

    Acute kidney injury (AKI) is most commonly caused by sepsis in critically ill patients, and it is associated with high morbidity and mortality. The pathophysiology of sepsis-induced AKI is generally accepted to include direct inflammatory injury, endothelial cell dysfunction, and apoptosis. Milk fat globule-epidermal growth factor-factor VIII (MFG-E8) is a secretory glycoprotein with a known role in the enhancement of apoptotic cell clearance and regulation of inflammation. We hypothesize that administration of recombinant mouse MFG-E8 (rmMFG-E8) can protect mice from kidney injuries caused by sepsis. Sepsis was induced in 8-wk-old male C57BL/6 mice by cecal ligation and puncture (CLP). rmMFG-E8 or phosphate-buffered saline (vehicle) was injected intravenously at a dosage of 20 μg/kg body weight at time of CLP (n = 5-8 mice per group). After 20 h, serum and renal tissue were harvested for various analyses. The renal injury markers blood urea nitrogen (BUN) and creatinine were determined by enzymatic and chemical reactions, respectively. The gene expression analysis was carried out by real-time quantitative polymerase chain reaction. At 20 h after CLP, serum levels of BUN and creatinine were both significantly increased in the vehicle group compared with the sham group, whereas the mice treated with rmMFG-E8 had a significant reduction in BUN and creatinine levels by 28% and 24.1%, respectively (BUN: 197.7 ± 23.6 versus 142.3 ± 20.7 mg/dL; creatinine: 0.83 ± 0.12 versus 0.63 ± 0.06 mg/dL; P sepsis through inhibiting the production of proinflammatory cytokines and chemokine, as well as through the activation of endothelial cells. Thus, MFG-E8 may have a therapeutic potential for treating AKI induced by sepsis. Copyright © 2017 Elsevier Inc. All rights reserved.

    We present measurements of the soft X-ray background (SXRB) O VII and O VIII intensity between l = 120 deg. and l = 240 deg., the first results of a survey of the SXRB using archival XMM-Newton observations. We do not restrict ourselves to blank-sky observations, but instead use as many observations as possible, removing bright or extended sources by hand if necessary. In an attempt to minimize contamination from near-Earth solar wind charge exchange (SWCX) emission, we remove times of high solar wind proton flux from the data. Without this filtering we are able to extract measurements from 586 XMM-Newton observations. With this filtering, ∼1/2 of the observations are rendered unusable, and we are able to extract measurements from 303 observations. The oxygen intensities are typically ∼0.5-10 photons cm -2 s -1 sr -1 (line units, L.U.) for O VII and ∼0-5 L.U. for O VIII. The proton flux filtering does not systematically reduce the oxygen intensities measured from a given observation. However, the filtering does preferentially remove the observations with higher oxygen intensities. Our data set includes 69 directions with multiple observations, whose oxygen intensity variations can be used to constrain SWCX models. One observation exhibits an O VII enhancement of ∼25 L.U. over two other observations of the same direction, although most SWCX enhancements are ∼ 6 K, in good agreement with previous studies.

    Markers for endothelial cells including Ulex europaeus 1 lectin, blood group A, B, and H, and the prostaglandin metabolite 6-keto-PGF1 alpha were evaluated in paraffin secretions from formalin-fixed benign and malignant vascular neoplasms using a variety of immunohistochemical techniques, and results compared with staining for factor VIII-related antigen. Staining for Ulex appeared more sensitive than factor VIII-related antigen in identifying poorly differentiated neoplasms including haemangiosarcomas and spindle cell proliferations in Kaposi's sarcoma. Staining for blood group related antigens correlated with blood group in all cases. Ulex europaeus 1 lectin was the only marker for endothelial cells in lymphangiomas.

    This article examines the regionalization process in the Brazilian Health System, identifying frameworks and challenges of this process from critical dialogue on the subject, contextualized by the experience of the management system and in the light of an established theoretical debate in the last decade. We used the thematic content analysis of legal and documentary surveys of the regionalization process in SUS, collated by elements of the historical and political context in the period. As evidence, it appears that the regionalization process has been incremental decentralization/deconcentration of management and health actions and services. There are important challenges, particularly in relation to ensuring access and system governance structure, which contributes to critical thinking and construction of new perspectives by those who lead their implementation.

    Between January and December 2013, the dental and periodontal health of 99 Swedish wild boars (Sus scrofa) was investigated. Sampling occurred in conjunction with routine hunting at six large estates in the southern and middle parts of Sweden. All six of the estates use supplemental feeding. The weight of the animals, their sex and their dates of death were noted. Age was estimated using tooth eruption and tooth replacement patterns. The oral cavity was inspected and abnormalities were recorded on a dental chart modified for wild boars. The findings included supernumerary teeth, absence of teeth, mild class II malocclusion, severe tooth wear, periodontitis, calculus, caries, tooth fractures and the presence of enamel defects. Swedish wild boars suffer from different dental lesions and the impact of supplemental feeding on dental and periodontal health is still to be investigated. Copyright © 2015 Elsevier Ltd.

    We used serology to estimate the prevalence of exposure to chlamydiae in Italian populations of wild boars (Sus scrofa). Sera from 173 hunter-killed wild boars harvested during the 2006-2009 hunting seasons in three Italian regions were tested for antibodies to Chlamydia suis, Chlamydophila pecorum, Chlamydophila abortus, and Chlamydophila psittaci by the microimmunofluorescence test. Antibody titers to chlamydiae ≥ 1:32 were detected in 110 of the 173 samples tested (63.6%). Specific reactivity could be assessed only in 44 sera with antibody titers to C. suis that were two- to threefold higher than antibody titers against the other chlamydial species; the other 66 sera had similar reactivity against all the chlamydia species tested. Antibody to C. suis was detected in sera from wild boar populations with rare or no known contact with domestic pigs. These results suggest that the wild boar could be a chlamydia reservoir and may acquire chlamydiae independent of contacts with the domestic pig.

  9. A fundamental study on stress corrosion cracking of SUS 304 steel in high temperature water

    Mukai, Yoshihiko; Murata, Masato

    1985-01-01

    SCC susceptibility of sensitized SUS 304 stainless steel in high temperature water was studied. The results obtained are as follows. SCC susceptibility was increased by adding crevices to the tensile specimen surface, for the corrodent became acidified by hydrolysis in crevices. SCC susceptibility was best fit to TTS curve obtained by EPR test, not by other corrosion tests such as Strauss test or the grain boundary corrosion test in high temperature water. In addition, by giving a simulated weld thermal cycle before the sensitizing heat treatment, the sensitization was clearly promoted. This seemed to be caused by the reason that nucleation of carbide occured in the simulated weld thermal cycle process and it promoted the carbide growth and the formation of Cr poor layer around carbide in the subsequent sensitization process.

    The microstructural changes have been examined in order to study the effect of titanium addition to type 316 stainless steels on void swelling. Titanium ions of 400 keV from an accelerator have been implanted at room temperature to solution treated SUS 316 stainless steels which have the original titanium content of 0.02 wt.% to the concentration increase of titanium by 0.01, 0.02 and 0.1 wt.%. Following the preinjection of 20 at.ppm helium at ambient temperature, 400 keV-aluminium ions have been irradiated to the specimen to 40 dpa at 550, 625 and 675 0 C. The TEM observations have revealed that the void number density is drastically increased in the specimen with the content of implanted titanium of more than 0.01 wt.%, whereas the void diameter is remarkably decreased with the titanium content.

    The mechanisms of forming nanostructured, nanophase layers are revealed and analyzed in austenitic steel subjected to surface alloying using an electron-plasma process. Nanostructured, nanophase layers up to 30 μm in thickness were formed by melting of the film/substrate system with an electron beam generated by a SOLO facility (Institute of High Current Electronics, SB RAS), Tomsk), which ensured crystallization and subsequent quenching at the cooling rates within the range 105-108 K/s. The surface was modified with structural stainless steel specimens (SUS 321 steel). The film/substrate system (film thickness 0.5 μm) was formed by a plasma-assisted vacuum-arc process by evaporating a cathode made from a sintered pseudoalloy of the following composition: Zr - 6 at.% Ti - 6 at.% Cu. The film deposition was performed in a QUINTA facility equipped with a PINK hot-cathode plasma source and DI-100 arc evaporators with accelerated cooling of the process cathode, which allowed reducing the size and fraction of the droplet phase in the deposited film. It is found that melting of the film/substrate system (Zr-Ti-Cu)/(SUS 321 steel) using a high-intensity pulsed electron beam followed by the high-rate crystallization is accompanied by the formation of α-iron cellular crystallization structure and precipitation of Cr2Zr, Cr3C2 and TiC particles on the cell boundaries, which as a whole allowed increasing microhardness by a factor of 1.3, Young's modulus - by a factor of 1.2, wear resistance - by a factor of 2.7, while achieving a three-fold reduction in the friction coefficient.

    Anodic polarization curves for a solution-treated or sensitized SUS 304 stainless steel and solution-treated Fe-Ni-Cr ternary alloys containing 10%Ni and 6 to 14%Cr have been measured in deaerated 0.5 mol/l Na/sub 2/SO/sub 4/ solutions of pH 2.0 to 5.9 at 298, 523 and 553 K. Corrosion potentials for U-bend SCC test specimens of sensitized SUS 304 stainless steel have also been monitored for a long time in the same solutions as those used for the polarization measurements except that they were aerated. It was found that the differences in the current densities in the passive state, i sub(pass), between the solution treated steel and the sensitized one and also between the ternary alloy with higher Cr content and the one with lower Cr content become large with increasing temperature and decreasing pH. This means that the difference in the values of i sub(pass) between grain bodies and Cr-depleted zones along grain boundaries of sensitized steel becomes larger and susceptibility to intergranular corrosion of the sensitized steel in the passivation region becomes higher with increasing temperature and decreasing pH. Since corrosion potentials for the U-bend SCC test specimens in air-satulated solutions lie in the passive region of anodic polarization curves for the sensitized steel in deaerated solutions, the intergranular stress-corrosion cracking of the sensitized steel in high temperature water with dissolved oxygen is considered to be caused by the preferential corrosion in the Cr-depleted zone.

  1. A novel link between Sus1 and the cytoplasmic mRNA decay machinery suggests a broad role in mRNA metabolism

    Full Text Available Abstract Background Gene expression is achieved by the coordinated action of multiple factors to ensure a perfect synchrony from chromatin epigenetic regulation through to mRNA export. Sus1 is a conserved mRNA export/transcription factor and is a key player in coupling transcription initiation, elongation and mRNA export. In the nucleus, Sus1 is associated to the transcriptional co-activator SAGA and to the NPC associated complex termed TREX2/THSC. Through these associations, Sus1 mediates the nuclear dynamics of different gene loci and facilitate the export of the new transcripts. Results In this study, we have investigated whether the yeast Sus1 protein is linked to factors involved in mRNA degradation pathways. We provide evidence for genetic interactions between SUS1 and genes coding for components of P-bodies such as PAT1, LSM1, LSM6 and DHH1. We demonstrate that SUS1 deletion is synthetic lethal with 5'→3' decay machinery components LSM1 and PAT1 and has a strong genetic interaction with LSM6 and DHH1. Interestingly, Sus1 overexpression led to an accumulation of Sus1 in cytoplasmic granules, which can co-localise with components of P-bodies and stress granules. In addition, we have identified novel physical interactions between Sus1 and factors associated to P-bodies/stress granules. Finally, absence of LSM1 and PAT1 slightly promotes the Sus1-TREX2 association. Conclusions In this study, we found genetic and biochemical association between Sus1 and components responsible for cytoplasmic mRNA metabolism. Moreover, Sus1 accumulates in discrete cytoplasmic granules, which partially co-localise with P-bodies and stress granules under specific conditions. These interactions suggest a role for Sus1 in gene expression during cytoplasmic mRNA metabolism in addition to its nuclear function.

    Full Text Available IntroductionPlasma factor VIII (FVIII and von Willebrand factor (VWF levels have been associated with the rate and severity of arterial thrombus formation and have been linked to outcomes following thrombolytic therapy in acute myocardial infarction patients. Here, we aimed to investigate FVIII and VWF levels during the course of thrombolysis in acute ischemic stroke (AIS patients and to find out whether they predict long-term outcomes.Materials and methodsStudy population included 131 consecutive AIS patients (median age: 69 years, 60.3% men who underwent i.v. thrombolysis with recombinant tissue plasminogen activator (rt-PA. Blood samples were taken on admission, 1 and 24 h after rt-PA administration to measure FVIII activity and VWF antigen levels. Neurological deficit of patients was determined according to the National Institutes of Health Stroke Scale (NIHSS. ASPECT scores were assessed using computer tomography images taken before and 24 h after thrombolysis. Intracranial hemorrhage was classified according to the European Cooperative Acute Stroke Study (ECASS II criteria. Long-term functional outcome was determined at 90 days after the event by the modified Rankin scale (mRS.ResultsVWF levels on admission were significantly elevated in case of more severe AIS [median and IQR values: NIHSS <6:189.6% (151.9–233.2%; NIHSS 6–16: 199.6% (176.4–250.8%; NIHSS >16: 247.8% (199.9–353.8%, p = 0.013]; similar, but non-significant trend was observed for FVIII levels. FVIII and VWF levels correlated well on admission (r = 0.748, p < 0.001 but no significant correlation was found immediately after thrombolysis (r = 0.093, p = 0.299, most probably due to plasmin-mediated FVIII degradation. VWF levels at all investigated occasions and FVIII activity before and 24 h after thrombolysis were associated with worse 24 h post-lysis ASPECT scores.

    Full Text Available El propósito de este artículo es evidenciar, mediante el método etnográfico, las creencias sobre la obesidad de niños y niñas en edad escolar y las de sus progenitores, pertenecientes a una escuela urbana y pública de San José, Costa Rica. Los resultados apuntan hacia las creencias negativas de la niñez respecto a sus pares con obesidad y sus implicaciones psicosociales y afectivas. En relación con los progenitores se señalan las causas y estrategias de control, las implicaciones de la obesidad, referente a enfermedades físicas y emocionales; el papel del hogar y de la escuela en su prevención. Se concluye que los niños y las niñas creen que la obesidad no es una enfermedad, sino u na expresión fenotípica, a la cual le dan grado de relatividad o de escala y la consideran no deseable, resultado que concuerda con la de sus progenitores. Las niñas participantes con obesidad expresaron sus posiciones de defensa y molestia, en relación con experiencias burlescas. Al contrario de sus hijos e hijas, la mayoría de los progenitores sí cree que la obesidad es una enfermedad o un problema de salud o de estética. Además, estiman que esta se controla utilizando una dieta saludable y equilibrada, dando consejos sobre las consecuencias físicas y emocionales de la obesidad y ofreciendo modelos de personas saludables. Por lo tanto, los progenitores y el personal docente creen que la escuela poco puede hacer respecto a la alimentación saludable del alumnado, pues el hogar es el lugar que tiene un papel primordial.

    Full Text Available Bajo cualquier esquema de enseñanza-aprendizaje de la matemática, cuando al alumno se le señalan errores en su trabajo, puede, en general, adoptar tres tipos de actitud: una actitud negativa, bajo la cual el alumno considera que sus errores son sencillamente un síntoma de su fracaso; una actitud neutra o indiferente ante sus errores; o una actitud positiva, considerándolos como un medio para aprender y planteándose como reto el superarlos. Este artículo muestra una investigación que abordó el estudio de actitudes vinculadas al proceso de aprendizaje de la matemática. Su objetivo fue describir la actitud que el estudiante de ingeniería de la Uni- versidad del Zulia exhibe frente a sus errores cuando aprende matemática. La sus tentación teórica se baso en Brousseau (2001, Briñol et al. (2007 y los autores Pallí y Martínez (2004. Se utilizó una escala AEAM (Actitud hacia el Error del Alumno de Matemática, tipo Likert con 6 alternativas de respuesta que consta de 36 ítems, en su segunda versión, actualizada por los autores. El instrumento fue validado mediante juicio de expertos y se determinó que era de alta confiabilidad, con un alpha de Cronbach de 0.9073. Se concluyó que los participantes, en su mayoría, mostraron una actitud moderadamente positiva hacia sus errores, que al no estar ubicada en el extremo positivo deseable refleja una actitud débil que no garantiza una conducta adecuada hacia los errores, pero que sin embargo es sus ceptible de ser mejorada hacia una actitud francamente positiva.

This process may involve multiple steps that might create a barrier to adherence. A new dual-chamber syringe (DCS; FuseNGo® was recently introduced with the aim of simplifying reconstitution. Aim: This study aimed to identify factors associated with adult patients’ preferences for different coagulation factor VIII reconstitution systems and to test ease of use and patient preference for the DCS. Methods: A cross-sectional survey of adults with hemophilia A in five European countries was conducted; a subset of subjects also participated in a practical testing session of the DCS. Results: Among the 299 survey participants, the device scenario requiring the least equipment and reconstitution steps (the DCS received a median preference rating of 71 out of 100 (0 being “the least desirable” and 100 “the most desirable” rating. This was significantly higher than the other scenarios (the next highest achieved a median of 50 points; P<0.001. Participants would be more likely to use this device prophylactically (P<0.001.

    Essentials Research suggests that intensive treatment episodes may increase the risk to develop inhibitors. We performed an international nested case-control study with 298 non-severe hemophilia A patients. Surgery and a high dose of factor VIII concentrate were associated with increased inhibitor risk. Physicians need to review arguments for factor VIII dose and elective surgery extra critically. Background Inhibitor development is a major complication of treatment with factor VIII concentrates in hemophilia. Findings from studies among severe hemophilia A patients suggest that intensive treatment episodes increase the risk of developing inhibitors. Objectives We set out to assess whether intensive treatment is also associated with an increased risk of inhibitor development among non-severe hemophilia A patients. Patients/Methods We performed a nested case-control study. A total of 75 inhibitor patients (cases) and 223 control patients were selected from 2709 non-severe hemophilia A patients (FVIII:C, 2-40%) of the INSIGHT cohort study. Cases and controls were matched for date of birth and cumulative number of exposure days (EDs) to FVIII concentrates. Conditional logistic regression was used to calculate both unadjusted and adjusted odds ratios (aOR); the latter were adjusted for a priori specified confounders. Results Peak treatment of 5 or 10 consecutive EDs did not increase inhibitor risk (aOR, 1.0; 95% confidence interval (CI), 0.4-2.5; and aOR, 1.8; CI, 0.6-5.5, respectively). Both surgical intervention (aOR, 4.2; CI, 1.7-10.3) and a high mean dose (> 45 IU kg -1 /ED) of FVIII concentrate (aOR, 7.5; CI, 1.6-35.6) were associated with an increased inhibitor risk. Conclusions Our findings suggest that high-dose FVIII treatment and surgery increase the risk of inhibitor development in non-severe hemophilia A. Together with the notion that non-severe hemophilia A patients are at a lifelong risk of inhibitor development, we suggest that in the future physicians

    2012-01-01

    We present an all-sky catalog of diffuse O VII and O VIII line intensities, extracted from archival XMM-Newton observations. This catalog supersedes our previous catalog, which covered the sky between l = 120° and l = 240°. We attempted to reduce the contamination from near-Earth solar wind charge exchange (SWCX) emission by excluding times of high solar wind proton flux from the data. Without this filtering, we were able to extract measurements from 1868 observations. With this filtering, nearly half of the observations became unusable, and only 1003 observations yielded measurements. The O VII and O VIII intensities are typically ∼2-11 and ∼ –2 s –1 sr –1 (line unit, L.U.), respectively, although much brighter intensities were also recorded. Our data set includes 217 directions that have been observed multiple times by XMM-Newton. The time variation of the intensities from such directions may be used to constrain SWCX models. The O VII and O VIII intensities typically vary by ∼ 10 L.U. were observed. We compared our measurements with models of the heliospheric and geocoronal SWCX. The heliospheric SWCX intensity is expected to vary with ecliptic latitude and solar cycle. We found that the observed oxygen intensities generally decrease from solar maximum to solar minimum, both at high ecliptic latitudes (which is as expected) and at low ecliptic latitudes (which is not as expected). The geocoronal SWCX intensity is expected to depend on the solar wind proton flux incident on the Earth and on the sightline's path through the magnetosheath. The intensity variations seen in directions that have been observed multiple times are in poor agreement with the predictions of a geocoronal SWCX model. We found that the oxygen lines account for ∼40%-50% of the 3/4 keV X-ray background that is not due to unresolved active galactic nuclei, in good agreement with a previous measurement. However, we found that this fraction is not easily explainable by a

    The Lawrence Livermore National Laboratory (LLNL) Plutonium Packaging System (PuPS) prepares packages to meet the DOE Standard 3013 (Reference 1). The PuPS equipment was supplied by the British Nuclear Fuels Limited (BNFL). The DOE Standard 3013 requires that the welding of the Outer Can meets ASME Section VIII Division 1 (Reference 2). ASME Section VIII references to ASME Section IX (Reference 3) for most of the welding requirements, but UW-13.2 (d) of Section VIII requires a certain depth and width of the weld. In this document the UW-13.2(d) requirement is described as the (a+b)/2t s ratio. This ratio has to be greater than or equal to one to meet the requirements of UW-13.2(d). The Outer Can welds had not been meeting this requirement. Three methods are being followed to resolve this issue: (1) Modify the welding parameters to achieve the requirement, (2) Submit a weld case to ASME that changes the UW-13.2(d) requirement for their review and approval, and (3) Change the requirements in the DOE-STD-3013. Each of these methods are being pursued. This report addresses how the first method was addressed for the LLNL PuPS. The experimental work involved adjusting the Outer Can rotational speed and the power applied to the can. These adjustments resulted in being able to achieve the ASME VIII, UW-13.2(d) requirement

  18. Low-cycle fatigue properties of SUS304 stainless steel in high-temperature sodium

    International Nuclear Information System (INIS)

    Hirano, M.; Komine, R.; Kitao, K.; Nihei, I.; Yoshitoshi, A.

    Low-cycle fatigue tests in sodium and in air have been performed to investigate the influence of a high-temperature sodium environment on the strain-controlled fatigue behaviour for SUS304 stainless steel. The oxygen concentration in sodium was 2.4 ppm at the cold trap temperature of 145 deg. C. Tests in both environments were conducted at 450 deg. C, 550 deg. C and 650 deg. C at a constant strain rate of 1x10 -3 /sec with a fully-reversed triangular waveform and a zero mean strain. The fatigue life of SUS304 stainless steel in sodium at 450 deg. C, 550 deg. C and 650 deg. C was greater than those in air at the same temperature except at higher strain range (>0.8%) at 650 deg. C, and this difference had a tendency to increase as the total strain range decreases. At the higher total strain range at 650 deg. C, there was no marked difference between both environments. As the temperature increased, the fatigue life in sodium and in air decreased, and the Nsub(f sodium)/Nsub(f air) ratio also decreased. Microscopic examination of specimens tested in sodium and in air at 450 deg. C, 550 deg. C and 650 deg. C revealed no difference in the microstructure, but few surface cracks were observed on specimens tested in sodium than in those tested in air. Fractography of specimens tested in air at 450 deg. C, 550 deg. C and 650 deg. C revealed well-defined striations. But, in sodium, striations on specimens tested at 450 deg. C and 550 deg. C showed obscure configuration and it was difficult to find out, whereas, at 650 deg. C in sodium intergranular fracture was observed. The specimens tested in sodium had a longer fatigue life than those tested in air because the latter are subjected to considerable oxidation, while the former are free of such chemical action. Accordingly, it is concluded that crack initiation and propagation are more likely to occur in air than in sodium. (author)

    Full Text Available Habitat use by wild boar Sus scrofaz was examined during a three-year period in Moncayo Nature Park, a protected mountain area in the Iberian mountain system, Spain. Tracking indirect signs of activity was used to collect data on the species occurrence, according to vegetation type, topography, hunting activity, and season. The data were analysed using binary logistic regression. Habitat used by wild boar differed according seasons, management practices, and vegetation. Main selected habitats were at medium elevations (1,101-1,600 m in areas dominated by holm oak (Quercus ilex, beech (Fagus sylvatica and oak woods of Q. robur, Q. petraea and Q. pyrenaica. Non-hunting areas were selected over hunting areas. We found a seasonal variation in the habitat use of wild boar, with areas dominated by holm oak being used disproportionately in spring, and areas at medium elevations selected only during summer. The results also support the view that non-hunting areas provide a refuge for this species inside the protected area.Estudiamos el uso del hábitat por parte del jabalí Sus scrofa a lo largo de tres años en el Parque Natural del Moncayo, un área protegida de montaña en el Sistema Ibérico, España. Para ello rastreamos las huellas y señales de su actividad en función de la vegetación, topografía, actividad cinegética y estacionalidad. Los datos fueron analizados utilizando regresiones logísticas binarias. El hábitat usado por el jabalí difiere según las estaciones, gestión y vegetación. Los hábitat mayoritariamente seleccionados fueron las altitudes medias (1101-1600 m en áreas dominadas por la encina (Quercus ilex, haya (Fagus sylvatica y robles (Q. robur, Q. petraea y Q. pirenaica. Las zonas no cinegéticas fueron seleccionadas frente a las cinegéticas. Encontramos diferencias estacionales en el uso del hábitat, con un uso mayor al esperado de los encinares en primavera así como de altitudes medias durante el verano. Los

    Full Text Available RESUMEN Los hongos-roya (Uredinales, Basidiomycetes representan uno de los grupos de microorganismos fitoparásitos más diversos y con mayor importancia económica mundial en la producción agrícola y forestal. Se caracterizan por ser patógenos obligados y por presentar una estrecha coevolución con sus hospedantes vegetales. Su taxonomía se ha basado fundamentalmente en el estudio de caracteres morfológicos, resultando en muchos casos en la formación de taxones polifiléticos. Sin embargo, en los últimos años se han tratado de incorporar herramientas moleculares que conduzcan a la generación de sistemas de clasificación basados en afinidades evolutivas. En esta revisión se ofrece una mirada general a las características de los uredinales, enfatizando en el surgimiento reciente de estudios filogenéticos que plantean la necesidad de establecer una profunda revisión de la taxonomía de este grupo. Finalmente se alerta sobre la necesidad de que en dichos estudios taxonómicos se incluya un alto número de especies de royas neotropicales, pues esta zona es reconocida no sólo por su alta diversidad de hongos-royas, sino también por las características únicas de sus ciclos de vida. Palabras clave: filogenia, hongos-roya, Puccinia, secuenciación, teliosporas.

    Full Text Available The city of Buenos Aires was founded, for the second time 1580 essentially as an outpost of the Spanish Empire to be protected from Indian attacks and possible foreign incursion, basically Portuguese in origin. Thus, from the beginnings of the city's founding, African slaves were used for the defense of the city. They acted in the urban militias, and were outstanding in the defense and re-conquest of the city when the English attacked in 1806- 1807. Innumerable prizes and eulogies were followed by integration of segregated divisions with a white officer corps.After 1813, a series of decrees ordered owners to exchange slaves for use in the Wars of Independence. Thus, property owners were obliged to sell to the State a number of their slaves according to the work performed by the slaves. The slaves would enter the armies as free persons and would serve five years as 'front line" soldiers in order to obtain their freedom. This article studies the participation of the Afro-Argentines in the distinct 'fronts" of the armies of liberation. The paper also reflects on the opinions of the generals who commanded Afro-Argentine troops.//La ciudad de Buenos Aires fue fundada, por segunda vez, en 1580 esencialmente como un puesto de avanzada para que los españoles se protegieran de los indígenas y de una posible incursión extranjera de origen portugués.

    Sn(II), Ti(III), Cu(I),Fe(II), V(III) and V(II) can be titrated potentiometrically with cacotheline in 1-4 M hydrochloric acid, 0.5-2 M hydrochloric acid, 0.5-1.5 M sulphuric acid in presence of 4 ml of 10% EDTA solution in a total volume of 50 ml, 9-10 M phosphoric acid, 4-8 M acetic acid and 3-8 M acetic acid respectively. Cacotheline can be used for the assay of tin plate and solder. The cacotheline undergoes a 2-electron reduction reaction. A cacotheline solution (0.005 M) in 0.02 M hydrochloric acid is fairly stable for several months. The conditional redox potentials of cacotheline have been determined in sulphuric, phosphoric and acetic acid medium. (Author)

    2016-01-01

    This book presents a historical and scientific analysis as historical epistemology of the science of weights and mechanics in the sixteenth century, particularly as developed by Tartaglia in his Quesiti et inventioni diverse, Book VII and Book VIII (1546; 1554). In the early 16th century mechanics was concerned mainly with what is now called statics and was referred to as the Scientia de ponderibus, generally pursued by two very different approaches. The first was usually referred to as Aristotelian, where the equilibrium of bodies was set as a balance of opposite tendencies to motion. The second, usually referred to as Archimedean, identified statics with centrobarica, the theory of centres of gravity based on symmetry considerations. In between the two traditions the Italian scholar Niccolò Fontana, better known as Tartaglia (1500?–1557), wrote the treatise Quesiti et inventioni diverse (1546). This volume consists of three main parts. In the first, a historical excursus regarding Tartaglia’s lifetime,...

    Three processes of solutions of the Einstein-Maxwell equations for Bianchi - I, II, VIII, IX and Kantowski-Sachs-like cosmological models with perfect fluid in magnetohydrolodynamical regimem are presented. Diagonal Bianchi-like models are considered with two anisotropy direction in the maximum. Solutions are found for Bianchi-II and IX-like models with energy conditions to be analyzed. Solutions are found for Bianchi-IX and Kantowski-Sachs-Like models with positive electric conductivity and satisfering to the predominant energy conditions. Solutions are formed for isotropic Kantowski-Sachs-Like models satisfering to the equation of state p=λρ, 0 0, admiting, in addition to the perfect fluid, electric field only. It is shown that a class of Bertotti-Robinson-like solutions is unstable by perturbations and it is carried in Kantowski-Sachs-like models with non-null electric conductivity. (L.C.) [pt

    Hereditary sensory and autonomic neuropathy type VIII is a rare autosomal recessive inherited disorder. Chen et al. recently identified the causative gene and characterized biallelic mutations in the PR domain-containing protein 12 gene, which plays a role in the development of pain-sensing nerve cells. Our patient's family was included in Chen and colleagues' study. We performed a literature review of the PubMed library (January 1985 to December 2016) on hereditary sensory and autonomic neuropathy type I to VIII genetic disorders and their orofacial manifestations. This case report is the first to describe the oral manifestations, and their treatment, of the recently discovered hereditary sensory and autonomic neuropathy type VIII in the medical and dental literature. We report on the oral manifestations and dental management of an 8-month-old white boy with hereditary sensory and autonomic neuropathy-VIII over a period of 16 years. Our patient was homozygous for a mutation of PR domain-containing protein 12 gene and was characterized by insensitivity to pain and thermal stimuli, self-mutilation behavior, reduced sweat and tear production, absence of corneal reflexes, and multiple skin and bone infections. Oral manifestations included premature loss of teeth, associated with dental traumata and self-mutilation, severe soft tissue injuries, dental caries and submucosal abscesses, hypomineralization of primary teeth, and mandibular osteomyelitis. The lack of scientific knowledge on hereditary sensory and autonomic neuropathy due to the rarity of the disease often results in a delay in diagnosis, which is of substantial importance for the prevention of many complications and symptoms. Interdisciplinary work of specialized medical and dental teams and development of a standardized treatment protocols are essential for the management of the disease. There are many knowledge gaps concerning the management of patients with hereditary sensory and autonomic neuropathy-VIII

    In eukaryotes, the nuclear export of mRNAs is essential for gene expression. However, little is known about the role of mRNA nuclear export in the important fungal pathogen, Candida albicans. In this study, we identified C. albicans Sus1, a nucleus-localized protein that is required for mRNA export. Interestingly, the sus1Δ/Δ displayed hyper-sensitivity to extracellular oxidative stress, enhanced ROS accumulation and severe oxidative stress-related cell death. More strikingly, although the mutant exhibited normal activation of the expression of oxidative stress response (OSR) genes, it had attenuated activity of ROS scavenging system, which may be attributed to the defect in OSR mRNA export in this mutant. In addition, the virulence of the sus1Δ/Δ was seriously attenuated. Taken together, our findings provide evidence that the mRNA export factor Sus1 plays an important role in oxidative stress tolerance and pathogenesis. Copyright © 2018 Elsevier Inc.

    Purpose: The aim of this study is to evaluate the efficacy of the driven equilibrium radio frequency reset pulse (DRIVE) on image quality and nerve detection when used in adjunction with T2-weighted 3D turbo spin-echo (TSE) sequence. Materials and methods: Forty-five patients with cranial nerve symptoms referable to the cerebellopontine angle (CPA) were examined using a T2-weighted 3D TSE pulse sequence with and without DRIVE. MR imaging was performed on a 1.5-T MRI scanner. In addition to the axial resource images, reformatted oblique sagittal, oblique coronal and maximum intensity projection (MIP) images of the inner ear were evaluated. The nerve identification and image quality were graded for the cranial nerves V-VIII as well as inner ear structures. These structures were chosen because fluid-solid interfaces existed due to the CSF around (the cranial nerves V-VIII) or the endolymph within (the inner ear structures). Statistical analysis was performed using the Wilcoxon test. P<0.05 was considered significant. Results: The addition of the DRIVE pulse shortens the scan time by 25%. T2-weighted 3D TSE sequence with DRIVE performed slightly better than the T2-weighted 3D TSE sequence without DRIVE in identifying the individual nerves. The image quality was also slightly better with DRIVE. Conclusion: The addition of the DRIVE pulse to the T2-weighted 3D TSE sequence is preferable when imaging the cranial nerves surrounded by the CSF, or fluid-filled structures because of shorter scan time and better image quality due to reduced flow artifacts.

    Full Text Available El estudio de la evolución de la cancillería real de Castilla bajo Alfonso VIII permite derivar ciertas conclusiones sobre el papel individual de los miembros de su personal en la redacción de los diplomas regios, concretamente por medio de un análisis detenido de los preámbulos, su formación y alteraciones a lo largo del tiempo en la mano de los distintos scriptores. Asimismo, esta base permite medir el equilibrio entre tradición e innovación en el trabajo de cancillería. La consideración de la imagen del monarca ideal, tal como se propone tanto en fuentes literarias como en los mismos documentos de la cancillería, conduce a una comprensión más clara del alcance de la propaganda política de la época en el más amplio contexto cultural de la corte castellana.The study of the Castilian royal Chancery’s evolution under King Alfonso VIII allows us to draw certain conclusions on the role of individual members of that office in the process of drafting royal documents. We will present a detailed description of preambles, their elaboration and evolution in time and by the hands of different scriptores. This will also allow us to gauge the balance between tradition and innovation within the Chancery. A more thorough grasp of the scope of political propaganda at the time can be determined through the image of the ideal king as depicted both in literary sources and in Chancery documents within the wider context of cultural developments in the Castilian court.

Reflexiona sobre la forma en que ambas cristiandades trataron el problema que las imágenes representan para las prácticas religiosas y las consecuencias políticas del culto de los iconos. El escrito afirma también que durante los siglos VIII y IX la crisis iconoclasta permitió la aparición de una tradición cristiana latina consciente de sí misma. Por lo tanto, se trató del momento que puso en evidencia el nacimiento de dos formas divergentes de piedad cristiana y la alienación de una respecto de la otra. La cristiandad occidental centrada en el edificio eclesiástico y que privilegiaba la ubicación de lo sagrado en el rito eucarístico, y la oriental cuyo centro era la adoración de las imágenes, con la consecuente multiplicación de los espacios sagrados.The following paper deals with the reception in the Carolingian west of the Byzantine Iconoclast Crisis. It considers the way both Christianities dealed with the problem that images presented to religious practices and the political consequences of iconic worship. The paper also states that during the VIII and IX centuries the iconoclast crisis allowed the emergence of a self conscious Latin Christian tradition. Consequently it was the moment that showed the beginning of two differing ways of Christian piety and the alienation of one towards the other. Western Christianity focused its religion practice in church building and the idea of Sacrality in the Eucharistic Rite. The oriental church, moreovers, centered its practices and theology on icon worship.

    Full Text Available OBJECTIVE: Nowadays recombinant factor VIII is produced in murine cells including in Chinese hamster ovary (CHO and baby hamster kidney cells (BHK. Previous studies, using the murine leukemia virus-derived retroviral vector pMFG-FVIII-P140K, modified two recombinant human cell lines, HepG2 and Hek293 to produce recombinant factor VIII. In order to characterize these cells, the present study aimed to analyze the integration pattern of retroviral vector pMFG-FVIII-P140K.METHODS: This study used ligation-mediated polymerase chain reaction to locate the site of viral vector integration by sequencing polymerase chain reaction products. The sequences were compared to genomic databases to characterize respective clones.RESULTS: The retroviral vector presented different and non-random profiles of integration between cells lines. A preference of integration for chromosomes 19, 17 and 11 was observed for HepG2FVIIIdB/P140K and chromosome 9 for Hek293FVIIIdB/P140K. In genomic regions such as CpG islands and transcription factor binding sites, there was no difference in the integration profiles for both cell lines. Integration in intronic regions of encoding protein genes (RefSeq genes was also observed in both cell lines. Twenty percent of integrations occurred at fragile sites in the genome of the HepG2 cell line and 17% in Hek293.CONCLUSION: The results suggest that the cell type can affect the profile of chromosomal integration of the retroviral vector used; these differences may interfere in the level of expression of recombinant proteins.

T2-weighted 3D TSE sequence with DRIVE performed slightly better than the T2-weighted 3D TSE sequence without DRIVE in identifying the individual nerves. The image quality was also slightly better with DRIVE. Conclusion: The addition of the DRIVE pulse to the T2-weighted 3D TSE sequence is preferable when imaging the cranial nerves surrounded by the CSF, or fluid-filled structures because of shorter scan time and better image quality due to reduced flow artifacts

    Full Text Available Se evaluó la virulencia de cepas de Listeria monocytogenes todas de serotipo 4b procedentes de cabras y sus derivados. Se observaron niveles de virulencia variables cuando se comparó la virulencia relativa (porcentaje de letalidad en ratones BALB/c inoculados vía intravenosa o intragástrica y su capacidad para infectar macrófagos J774A.1, y células epiteliales Caco-2. Dos cepas obtenidas de alimento de cabras produjeron 100 % de letalidad por ambas vías de inoculación y no mostraron diferencia significativa con la cepa testigo (P>0.05 respecto al porcentaje de invasión y a los parámetros de la cinética de crecimiento cuadrática observada en ambas líneas celulares. Si bien todas las cepas lograron invadir las células Caco-2, solamente algunas consiguieron invadir el bazo después de la inoculación por vía intragástrica. Las dos cepas provenientes de alimento de cabras fueron las más virulentas, representando un riesgo para la salud humana y animal, ya que pueden ser diseminadas en el hato y de este a otras explotaciones o a las instalaciones donde se elaboran alimentos.

    Full Text Available Los estudiosos de la familia residencial de las distintas disciplinas sociales en México no han tomado en cuenta las diferentes tradiciones culturales del país y han partido de un modelo de familia, como si México fuera un país homogéneo. El presente trabajo plantea el concepto de “sistema familiar mesoamericano”, que permite aprehender un tipo específico de ciclo de desarrollo de los grupos domésticos, característico de amplios sectores de la población rural de México. Uno de sus rasgos es la residencia virilocal, que favorece la formación de nuevas parejas sin necesidad de contar con vivienda propia. La consecuencia es una baja edad en el momento del matrimonio y el rápido crecimiento de la población, por lo que se puede hablar de un régimen demográfico asociado con este sistema familiar.

    Full Text Available Thirty pairs of kidneys of wild boar (Sus scrofa were studied from adult males, with permission from the Brazilian Institute of the Environment (Process nº 02001.003237/05, aiming to characterize the vasculature and anatomic surgical segmentation. The arteries of these kidneys were injected with red pigment and subsequently submitted to acid corrosion in order to identify the renal arterial vascular pattern, particularly its divisions and distribution. The results reveal the sectorial branches of the renal arteries, two in number (cranial and caudal; the sectorial arteries provide the segmentary branches to the dorsal and ventral portions of the kidney; in the right kidney, the segmentary branches are 2-6 in the cranial sector and 3-7 in the caudal sector. In the right kidney, the segmentary branches are 3-7 and 2-7 in the same respective sectors; the vascular arterial symmetry (25% between the right and left kidney in the animals is evident. There are 3 arterial anatomic surgical segments on both kidneys. On the basis of the distribution of the sectorial and segmentary arteries, it is possible to accomplish setorectomy and segmentectomy on the kidneys of the wild boar, with functional aspects such as species preservation and animal experimental modeling.

    Cyclic voltammograms of SUS 304 stainless steel in various neutral solutions such as Na 2 SO 4 at high temperature were measured, as a successive study to previous report in which effects of temperature and pH on polarization behavior of stainless steel were studied. In this measurement Ag/AgCl reference electrode and platinum counter electrode were used in a static autoclave lined with inconel. Passive films formed in various conditions were analysed by electron diffraction and Auger spectroscopy. Results obtained were compared with anodic behavior of iron, chromium and nickel and with thermodynamical stabilities of their compounds. The main results are summarized as follows. (1) Stainless steel shows such electrochemical behavior as active dissolution, passivation and transpassivation in a deaerated neutral solution at 250 0 C after fully reductive treatment of the specimen. In air-saturated solution, the peak of active dissolution is not observed. In the passive range there are intermediate oxidation and reduction peaks, and it is assumed that dissolved ionic species are oxidized to form oxide of spinel type and higher oxidized state successively at these peaks. (2) Electrochemical behavior of specimens in 0.1 M sulfate, -phosphate and -carbonate solutions are almost the same and rather thick films form in these solutions. On the other hand, specimens are easy to passivate in borate and -nitrate solution, and their passive films are thin. (author)

    Feral pigs (Sus scrofa L.) are perhaps the most abundant, widespread, and economically significant large introduced vertebrate across the Pacific island region. Unlike many other nonnative invasive species, feral pigs have both cultural and recreational importance in the region, complicating their management. Today, Pacific island feral pigs are a mixture of several strains of domestic swine, Asiatic wild boar, and European wild boar. Due to their generalist diet and rooting behavior, feral pigs alter soils and watersheds and negatively impact native and nonnative flora and fauna. As a result, feral pigs have played a role in the extinction of several species of plants and animals on Pacific islands and have negative effects on both ecotourism and agricultural industries in the region. Despite numerous published studies on feral pigs in the Pacific island region, of which the majority include systematic analyses of original empirical data, some fundamental aspects of feral pig ecology remain poorly characterized, at least partly due to the remote and inaccessible environments that they often inhabit. To address these knowledge gaps, effort should be made to integrate research conducted outside the Pacific island region into local management strategies. This review summarizes the origins, history, ecology, environmental effects, and current management of feral pigs in the Pacific island region; integrates regional scientific findings with those of other insular and continental systems; and identifies current knowledge gaps requiring further research to inform the ecology and management of this impactful invasive species.

    Bovine tuberculosis is a chronic disease of cattle ( Bos taurus ) caused by the bacterium Mycobacterium bovis . Efforts have been made in the US to eradicate the disease in cattle, but spillover into wildlife and subsequent spillback have impeded progress in some states. In particular, infection in white-tailed deer ( Odocoileus virginianus ) has been followed by infection in cattle in some Midwestern states. Infection has also been documented in feral swine ( Sus scrofa ) on the Hawaiian island of Molokai and in various European countries, but no large-scale survey of antibody exposure to the bacteria has been conducted in feral swine in the US. We tested 488 sera from feral swine collected near previously documented outbreaks of bovine tuberculosis in cattle and captive cervids, in addition to 2,237 feral swine sera collected across the US from 1 October 2013 to 30 September 2014. While all but one of the samples were antibody negative, the results are important for establishing baseline negative data since feral swine are capable reservoirs and could be implicated in future outbreaks of the disease.

    Full Text Available Antimicrobial resistance of bacteria is a worldwide problem affecting wild life by living with resistant bacteria in the environment. This study presents a discussion of outside factors environment on microflora of feral pigs (Sus scrofa from Brazilian Pantanal. Animals had samples collected from six different body sites coming from two separated geographic areas, Nhecolandia and Rio Negro regions. With routine biochemical tests and commercial kits 516 bacteria were identified, with 240 Gram-positive, predominantly staphylococci (36 and enterococci (186 strains. Among Gram-negative (GN bacteria the predominant specimens of Enterobacteriaceae (247 mainly represented by Serratia spp. (105, Escherichia coli (50, and Enterobacter spp. (40 and specimens not identified (7. Antimicrobial susceptibility was tested against 17 drugs by agar diffusion method. Staphylococci were negative to production of enterotoxins and TSST-1, with all strains sensitive towards four drugs and highest resistance toward ampicillin (17%. Enterococci presented the highest sensitivity against vancomycin (98%, ampicillin (94% and tetracycline (90%, and highest resistance pattern toward oxacillin (99%, clindamycin (83%, and cotrimoxazole (54%. In GN the highest resistance was observed with Serratia marcescens against CFL (98%, AMC (66% and AMP (60% and all drugs was most effective against E. coli SUT, TET (100%, AMP, TOB (98%, GEN, CLO (95%, CFO, CIP (93%. The results show a new profile of oxacillin-resistant enterococci from Brazilian feral pigs and suggest a limited residue and spreading of antimicrobials in the environment, possibly because of low anthropogenic impact reflected by the drug susceptibility profile of bacteria isolated.

    In a structural thermal fatigue test which imposed an oscillating axial temperature distribution on a SUS 304 pipe specimens, different crack initiation lives were observed between the inner and the outer surfaces, although the values of the von-Mises equivalent strain range calculated by FEM inelastic analysis were almost the same for both surfaces. The outer surface condition was an in-phase thermal cycle and an almost uniaxial cyclic stress (low hydrostatic stress). The inner surface condition was an out-of-phase thermal cycle and an almost equibiaxial cyclic stress (high hydrostatic stress). A uniaxial thermal fatigue test was performed under the simulated conditions of the outer and inner surfaces of the pipe specimen. The in-phase uniaxial thermal fatigue test result was in good agreement with the test result of the pipe specimen for the outer surface. The out-of-phase uniaxial thermal fatigue test which simulated the inner surface condition, showed a longer life than the in-phase uniaxial test, and thus contradicted the result of the structural model test. However, the structural model test life for the inner surface agreed well with the uniaxial experimental measurement when the strain range of the inner surface was corrected by a triaxiality factor

    Full Text Available Technological incorporation is a central topic among the concerns regarding health care systems. This paper discusses the role of technology dynamics in health systems' cost increases, suggesting two different approaches - a 'pragmatic-economic' approach and a 'rational-defensive' approach - as guidelines to explain the reasons for this centrality. The paper shows how judicialization results from this situation and discusses two doctrinal views - 'reserve for contingencies' and 'rational use' - as the views that usually guide the debates in the courts and among health policy makers. The paper suggests that the attitude currently prevalent in the Brazilian judiciary system can prejudice the principle of equity by improperly evaluating the principle of integrality. We present a brief genealogy of HTA and a timeline of HTA in Brazil. We also discuss the relevance and the impact of Law 12401/2011, which regulates the principle of integrality in the Unified Health System (SUS and propose three challenges to the development of HTA actions aiming at technology incorporation in Brazil. Finally, we discuss the entry and the role of private health insurance companies, emphasizing changes in the scenario and in their position.

    Full Text Available Selective laser sintering (SLS is a type of laminating sintering technique, using CO2 laser with (metal, polymer, and ceramic powders. In this result, the flake SUS 316L was used to achieve a high porous product, and compare to spherical type. After SLS, the porosity of flake-type sample with 34% was quite higher than that of the spherical-type one that had only 11%. The surface roughness of the flake SLS sample were also investigated in both inner and surface parts. The results show that the deviation of the roughness of the surface part is about 64.40μm, while that of the internal one was about 117.65μm, which presents the containing of high porosity in the uneven surfaces. With the process using spherical powder, the sample was quite dense, however, some initial particles still remained as a result of less energy received at the beneath of the processing layer.

    Creep-fatigue is a fatal failure mode of high temperature structural materials. It is recognized that the law of linear damage, according to which creep-fatigue damage is expressed by the sum of the creep damage and the fatigue damage, is inadequate to evaluate creep-fatigue damage. This is due to the fact that the law of linear damage does not include the effect of interaction between the creep damage and the fatigue damage. Consequently, development of direct measurement of damage accumulation on the sample of interest is required for plant life evaluation. In this study, the induced current focusing potential drop (ICFPD) technique was used to evaluate the depth of small surface cracks in SUS316FR stainless steel which was subjected to creep-fatigue damage. It is shown that the potential drop increased during the micro-crack initiation and propagation. Correspondingly, the ICFPD technique applied to estimate micro-crack depth changes was used to accurately evaluate the residual life of creep-fatigue damaged structural materials. (author)

    Light-absorbing aerosols, such as black carbon (BC), are major contributors to the atmospheric heating and the reduction of solar radiation reaching at the earth's surface. In this study, we investigate light-absorption and scattering properties of aerosols (i.e., BC mass concentration, aerosol solar-absorption/scattering efficiency) in the Kathmandu valley during Sustainable atmosphere for the Kathmandu valley (SusKat)-ABC campaign, from December 2012 to February 2013. Kathmandu City is among the most polluted cities in the world. However, there are only few past studies that provide basic understanding of air pollution in the Kathmandu Valley, which is not sufficient for designing effective mitigation measures (e.g., technological, financial, regulatory, legal and political measures, planning strategies). A distinct diurnal variation of BC mass concentration with two high peaks observed during wintertime dry monsoon period. BC mass concentration was found to be maximum around 09:00 and 20:00 local standard time (LST). Increased cars and cooking activities including substantial burning of wood and other biomass in the morning and in the evening contributed to high BC concentration. Low BC concentrations during the daytime can be explain by reduced vehicular movement and cooking activities. Also, the developmements of the boundary layer height and mountain-valley winds in the Kathmandu Valley paly a crucial role in the temproal variation of BC mass concentrations. Detailed radiative effects of light-absorbing aerosols will be presented.

    Full Text Available The objective of this investigation was to estimate the occurrence of infections by the three zoonotic bacteria Anaplasma phagocytophilum (A. phagocytophilum, Borrelia burgdorferi sensu lato (B. burgdorferi s.l. and Coxiella burnetii in wild boars (Sus scrofa in Central Italy. The spleen samples from 100 hunted wild boars were submitted to DNA extraction and PCR assays were carried out to detect the three agents. One (1% animal was positive for A. phagocytophilum, and three (3% for B. burgdorferi s.l. No positive reactions were observed for Coxiella burnetii. Wild boars did not seem to play an important role in the epidemiology of the three investigated agents. However, the detection of A. phagocytophilum and B. burgdorferi s.l. in the spleen of the tested animals showed that wild boars can harbor these pathogens, thus ticked that feeding on infected wild boars are likely to become infected, too, which represents a source of infection for other animals and humans. This is the first detection of A. phagocytophilum in wild boars in Italy.

    1985-01-01

    Under the condition of mechanical load, on which the thermal stress due to temperature change is superposed, the deformation behavior of structural materials is affected by not only loading history but also temperature history. Also at the time of working materials, the case that the relation between plastic deformation and temperature change becomes a problem is not few, such as cold working after hot rolling. In this study, the effect of temperature change exerted on the plastic deformation of SUS 304 stainless steel was examined, as this material has been frequently used as a high temperature structural material. That is, the plastic deformation behavior at a certain temperature after prestrain was applied at a different temperature was experimentally determined under various temperature and load conditions. Moreover, the quantitative evaluation of the results obtained was attempted by using the concept of an equal plastic strain curved surface. The test pieces and the experimental method, the behavior in uniaxial loading and the behavior in combined loading are reported. (Kako, I.)

    :  Feral swine ( Sus scrofa) are a pathogen reservoir for pseudorabies virus (PrV). The virus can be fatal to wildlife and contributes to economic losses in the swine industry worldwide. National surveillance efforts in the US use serology to detect PrV-specific antibodies in feral swine populations, but PrV exposure is not a direct indicator of pathogen transmission among conspecifics or to non-suid wildlife species. We measured antibody production and the presence of PrV DNA in four tissue types from feral swine populations of Florida, US. We sampled blood, nasal, oral, and genital swabs from 551 individuals at 39 sites during 2014-16. Of the animals tested for antibody production, 224 of 436 (51%) feral swine were antibody positive while 38 of 549 feral swine (7%) tested for viral shedding were quantitative polymerase chain reaction (qPCR)-positive for PrV. The detection of PrV DNA across all the collected sample types (blood, nasal, oral, and genital [vaginal] swabs) suggested viral shedding via direct (oronasal or venereal), and potentially indirect (through carcass consumption), routes of transmission among infected and susceptible animals. Fourteen of 212 seronegative feral swine were qPCR-positive, indicating 7% false negatives in the serologic assay. Our findings suggest that serology may underestimate the actual infection risk posed by feral swine to other species and that feral swine populations in Florida are capable of shedding the virus through multiple routes.

    In the Fukushima Dai-ichi nuclear power plant, seawater and natural river water were poured into the spent nuclear fuel pools (SFP) for emergency cooling. At the early stage of the accident, corrosion of SFP's materials was worried because of high chloride ion concentration from seawater. The chloride ion concentration of the present time was decreased by dechlorination operation of feeding water of SFPs. However, the water was not treated in the viewpoint of microbial breeding and SFPs were in contact with open atmosphere, so that many microbes could be alive in the cooling water. Some researchers have reported microbially induced corrosion (MIC) occurred in the natural seawater or river water. So, we attempted to examine the ability of MIC occurrence by using of corrosion potential analysis. Corrosion potential measurements were performed in test solutions using SUS304 simple plate, creviced and welded samples. Natural river water in Ibaraki prefecture was used as standard test solution, and some amounts of NaCl and nutrient broth (NB) were added to the other solutions. Temperatures of these solutions were kept in 303 K. Growth of microbes in the test solution was confirmed using test kit. Corrosion potentials of all samples rose to about 300 mV nobler than the initial values in the NB added solution. The potentials of the welded samples more easily rose than the simple plate. These potential changes are attributed to the biofilms formed on the sample surface. (author)
