Full textAbstract:
The purpose of this study is to provide the United States Marine Corps (USMC) with an analysis of Windows NT 5.0 Network Operating System (NOS). This analysis will assist the Network Operations Center (NOC) in preparation for the eventual migration of Windows NT 5.0 into the Marine Corps Enterprise Network (MCEN). NT 5.0 offers some significant enhancements over earlier versions. Active Directory provides a unified platform to manage NOS resources by storing user information, network shares and policies. NT File System (NTFS) version 5 permits dynamic allocation of primary storage space to each user. NT 5.0 also improves network security by incorporating use of the Kerberos Version 5 protocol, providing integrated security for authentication and file encryption. A top-down migration strategy should be incorporated by the NOC. Particularly important is how the NOC builds the Domain Naming Service (DNS) conventions for the MCEN. This will require every subordinate unit to adhere to the naming convention of its chain of command. Migrating from Banyan Vines to Windows NT presents a significant change to the organization. An effective Change Management strategy can assist members of the organization in understanding the sense of loss and uncertainty that occur in times of transition, and to deal with these changes effectively

Full textAbstract:
A large hydraulic Unimate 2000B robot was donated to the University of Canterbury by Industrial Research Ltd. Christchurch. The original point-to-point control system was spread across 8 A3 size large circuit boards. A desktop personal computer running Microsoft Windows NT on a VenturCom RTX kernel is used with a FPGA and custom A5 sized circuit board to replace the original system with path control. VenturCom’s Real Time extensions to the NT operating produced satisfactory Real Time operation for controlling the hydraulic manipulator, with a worst case interrupt latency of 27μs on a 233MHz Pentium II, and interrupt rates of up to 6kHz.
Full path control via a graphical user interface has been developed to provide the Robot with greater flexibility than was available with the original point-to-point control system. A PI controller was used for the control algorithm, with the tuning constants found by using frequency response analysis. This type of controller was found to work to a reasonable level of accuracy, although further investigation into an adaptive model controller could perhaps provide better performance.

Migration from an existing information technology system to a new system presents many managerial challenges. There are technological challenges associated with running the old system, maintaining data integrity and bringing the new system online all without seriously impacting daily operations. There are human factors to consider like resistance to change and conflict management. In addition, organizational issues like management support and cross functional communication channels need to he addressed. This thesis reviews the technical migration from an operational NetWare network to Windows NT completed at the Defense Manpower Data Center (DMDC) in Monterey, CA. The DMDC case presents a typical set of issues that an IT manager is likely to face when implementing technology driven change. Technical, human and organizational factors of technical change are discussed. A list of lessons learned and a set of technical management guidelines are derived from analysis of the DMDC case. Details of Windows NT 4.0 and 5.0 features are included.

Full textAbstract:
A esclerose sistêmica (ES) é uma doença difusa do tecido conjuntivo caracterizada por fibrose e envolvimento vascular, com distúrbio generalizado da microcirculação, podendo resultar em hipertensão arterial pulmonar (HAP). Atualmente, com o avanço no tratamento das crises renais, a mortalidade desses pacientes está relacionada basicamente ao envolvimento pulmonar. A HAP grave é de difícil tratamento e de mal prognóstico. O gene do peptídeo natriurético tipo B (BNP) codifica um pró-hormônio que é clivado no cardiomiócito produzindo o hormônio ativo BNP e o fragmento N-terminal do proBNP (NT-proBNP), biologicamente inativo, mas secretado na circulação em quantidades equimolares ao BNP. O NT-proBNP, uma molécula maior contendo 76 aminoácidos, tem meia-vida plasmática mais longa do que a do BNP (120 minutos versus 20 minutos) e, conseqüentemente, níveis circulantes mais elevados, o que facilita sua dosagem do ponto de vista analítico. Os níveis de NT-proBNP estão aumentados não somente em pacientes com insuficiência cardíaca congestiva e infarto agudo do miocárdio, mas também naqueles com hipertensão arterial pulmonar. Esta revisão aborda aspectos gerais do diagnóstico e manejo da esclerose sistêmica, com ênfase no envolvimento pulmonar; contempla também avaliação da estrutura e da importância dos peptídeos natriuréticos, com foco no NT-proBNP relacionado à hipertensão arterial pulmonar e esclerose sistêmica.Systemic sclerosis (SSc) is a diffuse connective tissue disease, characterized by skin and visceral fibrosis and vascular dysfunction. It may lead to pulmonary arterial hypertension (PAH). Currently, with the advance in the treatment of renal problems, the mortality of these patients is related basically to pulmonary envolvement. Severe HAP is difficult to treat and has a poor prognosis. The B-type natriuretic peptide (BNP) gene encodes a pro-hormone, which is cleaved in the cardiomyocyte to produce the hormone, BNP, and the biologically inactive N-terminal proBNP (NT-proBNP) fragment. Both are secreted in equimolar quantities. NT-proBNP, composed of 76 amino acids, has a longer half-life than BNP (120 minutes versus 20 minutes), and thus higher circulating levels and better analytical performance. The NTproBNP levels are raised in patients with congestive heart failure, acute myocardial infarction and also in pulmonary arterial hypertension. This review highlights general aspects of diagnosis and management of systemic sclerosis, emphasizing pulmonary involvement. It also assesses the structure and importance of natriuretic peptides, focusing on the NT-proBNP related to pulmonary hypertension and systemic sclerosis.

The Lincoln Adaptable Real Time Information Assurance Testbed (LARIAT) project is the first fully automatable network testbed for the evaluation of information assurance (IA) technologies. It allows researchers to easily set up experiments that evaluate the accuracy of host-based and network-based intrusion detection systems (IDSs). Initially, the network traffic it could produce used UNIX services and protocols as implemented for the Linux and Solaris platforms. However, due to the widespread deployment of Windows-based systems in production environments, it is necessary to include Windows-based traffic when testing IA systems in order to provide a comprehensive evaluation. This thesis describes WinNTGen, a Windows network traffic generation system that integrates into the existing LARIAT framework and enables it to produce Windows-based network traffic. To do this, WinNTGen simulates the actions of a user controlling applications that in turn use network resources. This frees WinNTGen from the need to re-implement network protocols and allows it to operate at a higher level of abstraction. WinNTGen controls applications via loadable libraries that encapsulate the manner in which a typical user interacts with a particular application. The statistical parameters that specify the behavior of a user with each application are derived from real users' behavioral data as they interacted with each application. The system is flexible and extensible so that different versions of the same application as well as additional applications can be controlled by modifying and adding libraries. Finally, the reality and the throughput of the network traffic produced by the WinNTGen system are evaluated.

Full textAbstract:
Background: Hyperthyroidism has substantial effects on the circulatory system. The cardiac biomarkers NT-proBNP and troponin I (cTNI) have proven useful in identifying cats with myocardial disease but have not been as extensively investigated in hyperthyroidism.Hypothesis: Plasma NT-proBNP and cTNI concentrations are higher in cats with primary cardiac disease than in cats with hyperthyroidism and higher in cats with hyperthyroidism than in healthy control cats.
Animals: Twenty-three hyperthyroid cats, 19 cats with HCM without congestive heart failure, and 19 euthyroid, normotensive healthy cats eight years of age or older. Fourteen of the hyperthyroid cats were re-evaluated three months after administration of 131I.
Methods: A complete history, physical examination, complete blood count, serum biochemistries, urinalysis, blood pressure measurement, serum T4 concentration, plasma concentrations of NT-proBNP and cTNI, and echocardiogram was prospectively obtained from each cat.
Results: Hyperthyroid and HCM cats had plasma NT-proBNP and cTNI concentrations that were significantly greater than healthy older cats, but there was no significant difference between hyperthyroid and HCM cats with respect to concentration of either biomarker. In hyperthyroid cats that were re-evaluated three months after 131I treatment, plasma NT-proBNP and cTNI concentrations as well as ventricular wall thickness decreased.
Conclusions and Clinical Relevance: Although there may be a role for NT-proBNP in monitoring the cardiac response to treatment of hyperthyroidism, neither NT-proBNP nor cTNI can be used to distinguish hyperthyroid cats from cats with HCM. Therefore, the thyroid status of older cats should be ascertained prior to interpreting results of cardiac biomarker testing.

INTRODUÇÃO: A estenose aórtica, doença valvar de grande prevalência, tem na avaliação clínica e ecocardiográfica as principais ferramentas para avaliação dos pacientes. Ferramentas auxiliares de avaliação são desejáveis e neste contexto surgem os peptídeos natriuréticos. Os peptídeos natriuréticos BNP e NT-proBNP podem ser usados como marcadores diagnósticos e prognósticos em diversas situações clínicas. Postulamos que os peptídeos pudessem ter papel diagnóstico, mas principalmente valor prognóstico em pacientes com estenose aórtica grave. OBJETIVO: primariamente, definir o papel prognóstico de sobrevida dos peptídeos natriuréticos BNP e NT-proBNP no acompanhamento prospectivo de uma população de pacientes com estenose aórtica grave. Secundariamente, comparar os níveis séricos de BNP e NT-proBNP entre pacientes com EAo grave assintomáticos e sintomáticos. MÉTODOS: Foram incluídos de forma consecutiva 66 pacientes com estenose aórtica grave, definida pela presença de gradiente médio de pressão transvalvar aórtica maior que 40 mmHg. Os critérios de exclusão foram fibrilação atrial, outra valvopatia, cardiopatia associada, infecções ativas, neoplasias, doenças auto-imunes ou inflamatórias, insuficiência renal e obesidade. Dos 66 pacientes incluídos, 76% eram sintomáticos (50/66). Os sintomas foram definidos como dispnéia aos esforços, síncope ou angina. Na inclusão, todos os pacientes foram submetidos à avaliação clínica inicial, realização de ecocardiograma e dosagem de BNP e NT-proBNP. Os pacientes sintomáticos recebiam a indicação de tratamento cirúrgico e os pacientes assintomáticos eram conduzidos clinicamente. Os pacientes foram acompanhados prospectivamente. O desfecho clínico avaliado foi óbito cardiovascular, definido por morte súbita, morte por insuficiência cardíaca e óbito peri-operatório. RESULTADOS: Os pacientes foram acompanhados por 869 + 397 dias. Houve 11 óbitos durante o acompanhamento. Na inclusão, os níveis de BNP e NT-proBNP foram similares em assintomáticos e sintomáticos: BNP 72 (41-175) pg/mL versus 104 (46-270) pg/mL; p = 0,275 e NT-proBNP 676 (235-1356) pg/mL vs. 871 (310-2230) pg/mL; p = 0,226. Houve diferença entre os níveis de BNP e NT-proBNP e classe funcional (p < 0,001 e p < 0,001, respectivamente). Através da curva ROC foi determinado um valor de corte de BNP (105 pg/mL) e NT-proBNP (1500 pg/mL) capazes de predizer classe funcional III e IV (New York Heart Association), com área sob a curva de 0,806 e 0,786 respectivamente. BNP e NT-proBNP foram preditores de mortalidade (p=0,007 e p=0,001 respectivamente). BNP > 105 pg/mL aumentou o risco de óbito cardiovascular de forma independente [OR= 6,3 (IC95%: 1,36 - 29,25)]. NT-proBNP > 1500 pg/mL aumentou o risco de óbito cardiovascular de forma independente [OR = 6,5 (IC95%: 1,73 - 24,63)]. CONCLUSÃO: O BNP e o NTproBNP foram preditores independentes de mortalidade em pacientes com estenose aórtica grave em um acompanhamento de quatro anos. O BNP e o NT-proBNP foram preditores de classe funcional III e IV (New York Heart Association) em pacientes com estenose aórtica grave. O BNP e o NT-proBNP não permitiram diferenciar pacientes sintomáticos de assintomáticosBACKGROUND: Aortic valve stenosis is a high prevalent cardiac valve disease, in which clinical and echocardiographic parameters are the most common approach of diagnosis and risk evaluation. Complementary methods are desirable and the natriuretic peptides BNP and NT-proBNP, both diagnostic and prognostic markers in multiple clinical situations, could improve patient assessment. We postulate that these peptides may have diagnostic purpose, but mainly a prognostic value in patients with severe aortic stenosis. OBJECTIVE: primarily, define the survival prognostic role of natriuretic peptides BNP and NT-proBNP in monitoring a population of patients with severe aortic stenosis prospectively. Secondarily, compare the serum levels of BNP and NT-proBNP among patients with symptomatic and asymptomatic severe aortic stenosis. METHODS: 66 consecutive patients with severe aortic stenosis, defined by the presence of gradient mean transvalvular aortic pressure greater than 40 mmHg were included. Exclusion criteria were concomitant atrial fibrillation, other valve disease, other myocardiopathies, active infections, autoimmunity diseases, inflammatory diseases, neoplasia, renal failure or obesity. 76% of patients were symptomatic (50/66), defined as dyspnea on exertion, syncope or angina. All patients underwent initial clinical evaluation, echocardiography and BNP and NT-proBNP measurement. Symptomatic patients were referred for surgical treatment and asymptomatic patients were clinically managed. (Patients were followed up prospectively). The clinical outcome was cardiovascular death, defined by sudden death, death from heart failure and peri-operative death. RESULTS: Patients were followed up for 869 + 397 days. There were 11 deaths during followup. On admission, levels of BNP and NT-proBNP were similar in asymptomatic and symptomatic individuals: BNP 72 (41-175) pg / mL vs. 104 (46-270) pg / mL, p = 0.275 and NT-proBNP 676 (235-1356) pg / mL vs. 871 (310-2230) pg / ml, p = 0.226. There were differences between the levels of BNP and NT-proBNP and functional class (p <0.001 p <0.001, respectively). ROC-curve analysis demonstrated a cut-off value of BNP (105 pg / mL) and NT-proBNP (1500 pg / mL) capable of predicting NYHA functional class III and IV, with an area under the curve of 0.806 and 0.786 respectively. BNP and NT-proBNP could predict mortality (p = 0.007 and p = 0.001 respectively). BNP > 105 pg/mL independently increased the risk of cardiovascular death [OR = 6.3 (95% CI: 1.36 to 29.25)]. NT-proBNP > 1500 pg/mL independently increased the risk of cardiovascular death [OR = 6.5 (95% CI: 1.73 to 24.63)]. CONCLUSION: BNP and NT-proBNP were independent predictors of mortality in patients with severe aortic stenosis after a follow up of 4 years. BNP and NT-proBNP were predictors of NYHA functional class III and IV in patients with severe aortic stenosis. BNP and NT-proBNP alone did not distinguish symptomatic from asymptomatic patients

Full textAbstract:
This work proposes some generic approaches to offer transparency and efficiency to checkpoint-recovery implementations on Windows. On the one hand, a complete environment is proposed to prepare Windows to incorporate transparently any checkpoint-recovery implementation whose architecture respects a simple contract of reusability. The environment allows any application to use some checkpoint-recovery services with only the default process creation mechanisms offered by Windows. Moreover, it handles automatically the recovery of the processes in case of a crash and requires no human intervention in most scenarios. On the other hand, an optimization module is proposed to minimize the checkpointing time and to slow its degradation in situations of high checkpoint-recovery demands. The results show an excellent control of the checkpoint cost degradation and sometimes the complete absence of the penalty associated with concurrent checkpoint requests.

Resumo: Esta dissertação de mestrado visa analisar a segurança dos protocolos de comunicação do sistema operacional Windows NT da Microsoft, especialmente quando usados em ambientes corporativos, onde é importante determinar se informações sigilosas estão adequadamente protegidas. Várias falhas importantes, de difícil correção, encontradas dispersas na bibliografia, foram apontadas e agrupadas. Novas e importantes vulnerabilidades foram descobertas, mostrando que mesmo o Windows 2000, a última versão deste sistema operacional, está sujeita a ataques eficientes que permitem sobrepujar esses protocolos de comunicação para obter informações sigilosas.
Abstract: This master thesis aims to assess Microsoft Windows NT operating system communication protocols security, mainly when used in corporation environments, where it is important to ascertain if sensitive information is adequately secured. Several important security faults, which are difficult to correct and are dispersed in bibliography, were pointed and grouped. Important new vulnerabilities were discovered, showing that even Windows 2000, the last version of this operating system, is subject to efficient attacks that allow supplanting those communication protocols in order to obtain sensitive information.

Afin d'etudier le mode de perception d'auxine dans les plantes de tabac, deux adnc de tabac, nt-erabp1 et nt-erabp2, codant pour une proteine homologue de la proteine de liaison d'auxine de mais (zm-erabp1) ont ete isoles. Les genes correspondants s'expriment preferentiellement dans les fleurs en cours d'elongation et dans les plantules. Neuf anticorps monoclonaux specifiques ont ete obtenus contre la proteine nt-erabp1 produite dans e. Coli. Ces anticorps, diriges contre au moins sept epitopes distincts de la proteine, offrent une couverture epitopique satisfaisante de la proteine nt-erabp1. Les neuf anticorps interferent avec la reponse electrique membranaire a l'auxine de protoplastes de tabac. Ces arguments demontrent l'implication de la proteine nt-erabp1 dans le systeme de perception d'auxine localise a la surface de la membrane plasmique. La plupart des anticorps inhibent la reponse electrique membranaire a l'auxine. En revanche, l'anticorps mab28 est capable, en absence d'auxine, de declencher cette reponse, mimant ainsi les effets de l'hormone. L'epitope reconnu par mab28 n'est inclus dans aucun des deux domaines de la proteine impliques dans la fixation de l'auxine. Cet effet agoniste pourrait resulter d'un changement de conformation de la proteine nt-erabp1 induit lors de la fixation de mab28. Ces resultats designent un nouveau site de regulation de la proteine nt-erabp1. La proteine nt-erabp1, et un peptide synthetique correspondant a sa region c-terminale, induisent l'hyperpolarisation de la membrane plasmique des protoplastes de tabac, reproduisant ainsi les effets des faibles concentrations en auxine. Afin de tester quels etaient les acides amines de la region c-terminale importants lors de l'interaction de la proteine nt-erabp1 avec la membrane plasmique, six proteines nt-erabp1, mutees dans le domaine c-terminal, ont ete etudiees. Pour obtenir des proteines correctement glycosylees, ces differentes proteines ont egalement ete produites en cellules d'insectes via baculovirus

Full textAbstract:
Bioremediation of seleniferous water is gaining more momentum, especially when it comes to bacterial reduction of the selenium oxyanions. More and more bacterial strains that are able to reduce selenium are being isolated. These bacteria need to be studied further to determine whether they are suited for industrial application. In this study, the reduction of Se(VI) to Se(0) by Pseudomonas stutzeri NT-I was examined using batch experiments with the bacteria suspended in MSM. For the determination of the optimum conditions for the growth of the bacteria, the linearized rate during the exponential phase for different conditions were compared. A pH of 7, temperature of 37 ⁰C, salinity of 20 g.L-1 NaCl and initial concentration of 5 mM selenate were found to be the best at promoting growth. To determine the optimum conditions for the reduction of selenium, the amount of Se(0) recovered from the plug after 16 hours of incubation was measured. A pH of 8, temperature of 37 ⁰C and salinity of 5 g.L-1 resulted in the most Se(0) recovered. The kinetics of the reduction of Se(VI) to Se(0) was found to follow the adapted Monod equation. An increase in the initial Se(VI) concentration positively affected the reduction rate indicating that substrate saturation had not yet been reached. One kmax could be fitted to each of the two reactions but not one Ks. It was found that Ks decreased with increasing initial selenate concentration. Visually it can be deduced that inhibition starts playing a role in the reduction of selenate at a concentration of 4 mM. Pseudomonas stutzeri NT-I is an exemplary selenium reducing agent and deserves more attention, not only for industrial application but also in the research world, for further understanding of the complex mechanism behind metal reduction in bacteria.Dissertation (MEng)--University of Pretoria, 2017.

Full textAbstract:
NT-proBNP is a biproduct derived from the synthesis of BNP, a synthesis stimulated when cardiomyocytes are stretched such as in heart failure. Heart failure is defined as the hearts inability to supply the blood volume the body acquires. It is advantageous to monitor changes for adequate treatment. NT-proBNP has proven to be an excellent marker for this purpose. The purpose of the study was to compare the two immunochemical methods for measuring NT-proBNP: Roche Elecsys proBNP II analyzed with Cobas e601 and Siemens IMMULITE 2000 NT-proBNP analyzed with IMMULITE 2000 XPi. For this comparison 60 lithium heparin plasma samples from 36 men (60 – 90 years old) and 24 women (65 – 94 years old) was used. IMMULITE 2000 XPi served as the reference method. Results from the assays were compared in a correlation diagram, which indicated good correlation (R: 0.98). Cobas e601 yielded results on average 17.4 % lower than the reference method. A paired t test was used to prove significant diference at 95 % confidence level between the methods on a 95 % confidence level. Precision regarding Roche Elecsys proBNP II, based on measurings of plasma with low and high analyte concentration, 25 replicates one day and 5 replicates 4 days gave imprecisions <3 % (CV%). Reference method imprecision (CV%) <5 % was calculated from control analysis. Good correlation between the two methods and lower imprecision when using proBNP II indicate that Cobas e601 can be used.NT-proBNP är en restprodukt vid syntes av brain natriuretic peptide (BNP), vars syntes stimuleras av att hjärtats myocyter töjs ut såsom vid hjärtsvikt. Hjärtsvikt innebär att hjärtat inte orkar pumpa den volym blod som motsvarar systemkretsloppets behov. Det är fördelaktigt att kunna följa förändringar i hjärtmuskelns funktion för adekvat behandling. NT-proBNP har visat sig vara en bra markör i detta syfte. Studiens syfte var att jämföra två immunokemiska metoder: Roches Elecsys proBNP II i analysinstrumentet Cobas e601 med Siemens IMMULITE 2000 NT-proBNP i analysinstrumentet IMMULITE 2000 XPi. Studiematerialet kom att bestå av 60 patientprover av litiumheparinplasma från 36 män (60 – 90 år) samt 24 kvinnor (65 - 94 år). IMMULITE 2000 Xpi fungerade som referensmetod. Resultat av kalibrering överensstämde med erhållna masterkurvor och analys av kontroller gav resultat inom 1 SD. Analysresultaten från de båda metoderna jämfördes i ett korrelationsdiagram. Spridningsdiagrammen indikerade en korrelation om R: 0,98. Jämförd metod gav dock i genomsnitt 17,8 % lägre resultat. Signifikant skillnad metoderna emellan vid 95 % konfidensnivå påvisades genom ett parat t-test. Precision avseende Roches Elecsys proBNP II undersöktes genom analys av plasma med hög respektive låg analytkoncentration (25 replikat samma dag och 5 replikat om dagen i ytterligare 4 dagar) vilket totalt gav en imprecision om <3 % uttryckt i CV. Referensmetodens imprecision beräknades utifrån analyserade kontroller och gav en CV <5 %. God korrelation mellan de båda metoderna samt lägre imprecision vid användning av Elecys proBNP II talar för att den jämförda metoden kan tas i bruk.

nÃo hÃAs doenÃas cardiovasculares, incluindo a cardiopatia isquÃmica aterosclerÃtica, sÃo a princi-pal causa de morte no Brasil. A aterosclerose à doenÃa inflamatÃria crÃnica que se inicia na infÃncia, progride lentamente e se expressa dÃcadas depois. Ela principia por disfunÃÃo do endotÃlio, tem patogÃnese multifatorial e tem, como principais fatores de risco, o sexo mascu-lino, a idade, o tabagismo, a hipercolesterolemia, a hipertensÃo arterial sistÃmica (HAS), o diabetes mellitus (DM) e o antecedente familiar de doenÃa aterosclerÃtica precoce. A elevaÃÃo de vÃrios marcadores bioquÃmicos sinaliza a participaÃÃo da inflamaÃÃo na aterosclerose. O peptÃdeo natriurÃtico tipo B e o fragmento amino-terminal do pro-peptÃdeo natriurÃtico tipo B (NT-proBNP) tambÃm aumentam na aterosclerose coronÃria. Esse trabalho à um estudo ob-servacional, transversal, de uma sÃrie consecutiva de 153 pacientes internados na Enfermaria de Cardiologia do HUWC-UFC, no perÃodo de 01.08.2007 a 31.03.2008, com hipÃtese diag-nÃstica de cardiopatia isquÃmica â angina estÃvel (AE), angina instÃvel (AI) ou infarto agudo do miocÃrdio (IAM) â submetidos à cineangiocoronariografia, comparando-se o grupo porta-dor de obstruÃÃo aterosclerÃtica coronÃria angiogrÃfica (grupo A) com aquele de artÃrias co-ronÃrias angiograficamente normais (grupo B). Os critÃrios de exclusÃo foram revasculariza-ÃÃo miocÃrdica prÃvia â cirÃrgica ou percutÃnea â insuficiÃncia renal dialÃtica aguda ou crÃni-ca, neoplasia maligna, infecÃÃo, doenÃa inflamatÃria aguda ou crÃnica, doenÃa pulmonar, he-pÃtica ou hematolÃgica e cardiopatia valvar, congÃnita ou cardiomiopatia associada. Ambos os grupos foram analisados, de modo semelhante, quanto ao sexo, à idade, à escolaridade, ao Ãndice de massa corporal (IMC), à circunferÃncia abdominal (CA), ao tabagismo, ao DM, à HAS, à histÃria familiar positiva para aterosclerose precoce, ao uso de estatina, à presenÃa de sÃndrome metabÃlica (SM) e à apresentaÃÃo clÃnica como AE, AI ou IAM. Eles tambÃm fo-ram analisados em relaÃÃo ao eletrocardiograma, à radiografia do tÃrax e ao ecocardiograma, quanto à presenÃa ou nÃo de disfunÃÃo sistÃlica; ao colesterol nÃo-HDL, à HDL-colesterol, à relaÃÃo do colesterol total / HDL-colesterol < 5 e do LDL-colesterol / HDL-colesterol < 3,5; à creatinina e o ao fibrinogÃnio, ao nÃmero de leucÃcitos totais e ao de monÃcitos, à proteÃna C reativa ultra-sensÃvel e ao NT-proBNP. A comparaÃÃo dos dois grupos revelou, com signifi-cÃncia estatÃstica, à anÃlise univariada, que os pacientes do grupo A tinham prevalÃncia maior de DM e de disfunÃÃo sistÃlica, NT-proBNP ≥ 250 pg/ml, fibrinogÃnio acima de 500 mg/dl; mais frequentemente usavam estatina e tinham monÃcitos 501 ou mais por mm3 do que aque-les do grupo B. Curiosamente, o IMC ≥ 30 e a CA aumentada foram mais prevalentes no gru-po com artÃrias coronÃrias normais. No entanto, pela regressÃo logÃstica multivariada, os fato-res independentes para oclusÃo aterosclerÃtica coronariana angiogrÃfica foram o NT-proBNP ≥ 250 pg/ml, o DM e o aumento do fibrinogÃnio e dos monÃcitos, mesmo consideradas a creatinina e a disfunÃÃo sistÃlica. Na amostra estudada, o modelo com ajuste de prevalÃncia desses fatores teve sensibilidade de 80,4%, especificidade de 76,9 e 79,7% de acurÃcia para o diagnÃstico de oclusÃo coronariana aterosclerÃtica angiogrÃfica.
Cardiovascular diseases, including ischemic heart disease, are the main causes of death in Brazil. Atherosclerosis is a chronic inflammatory disease that starts in the childhood, progresses slowly and shows up many decades later. It begins as an endothelial dysfunction and has as its main risk factors the male sex, age, smoking, hypercholesterolemia, arterial hypertension, diabetes mellitus and a background of early family atherosclerotic disease. The rise of many biochemical markers in the plasma signals the presence of inflammation in the atherosclerosis. The brain natriuretic peptide and the amino-terminal pro-B-type natriuretic peptide (NT-proBNP) also increase in coronary atherosclerosis. This is a cross-sectional and observational study of 153 in-patients at the Cardiology Ward of HUWC-UFC from 08.01.2007 to 03.31.2008 with the diagnostic hypothesis of Ischemic Heart Disease, i.e., stable angina, unstable angina or acute myocardial infarction. All of them underwent heart catheterization and coronary angiography. They were classified respectively as group A or B in accordance with the presence or not of angiographic atherosclerotic coronary occlusion. Patients were not included in the analysis if they had been submitted to surgical or percutaneous revascularization; had an acute or chronic dialytic kidney disease; cancer or infection; a lung, hepatic or hematopoietic disease; an acute or chronic inflammatory illness or associated myocardial, valvular or congenital heart disease. The two groups were analyzed in a similar way with regard to gender, age, level of education, body mass index, abdominal circumference, smoking, diabetes mellitus, arterial hypertension, an early atherosclerosis family history, the use of statin, presence of metabolic syndrome and clinical presentation of stable angina, unstable angina or acute myocardial infarction. The HDL-cholesterol, non HDL-cholesterol, a total cholesterol/HDL-cholesterol ratio < 5, a LDL-cholesterol/HDL-cholesterol ratio < 3.5, the creatinine and fibrinogen plasma concentration, the total leukocyte and monocyte count, the high-sensitivity C reactive protein, the NT-proBNP, the electrocardiogram, the chest radiography and the echocardiogram, with regard to the presence or not of systolic dysfunction, were also analyzed. The univariety analysis comparing both groups revealed that group Aâ patients more frequently were diabetics and had systolic dysfunction, NT-proBNP ≥ 250 pg/ml, fibrinogen higher than 500 mg/dl, more frequent use of statin and 501 or more monocytes/mm3 than patients group B. Curiously, the body mass index ≥ 30 and abnormal abdominal circumference were more frequently found among patients with angiographic normal coronary arteries. Nevertheless, by multivariety regression logistic analysis the independent factors for angiographic atherosclerotic coronary occlusion were the NT-proBNP ≥ 250 pg/ml, diabetes mellitus, an increase of monocyte number and of fibrinogen plasma concentration, in spite of creatinine level and presence of systolic dysfunction. The model takes into account these factors has 80.4% sensitivity, 76.9% specificity and 79.7% of accuracy for the diagnostic of angiographic atherosclerotic coronary occlusion.

Full textAbstract:
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, NevadaUpgrading or replacing production systems is always a very resource-consuming task, in particular if the systems being replaced are quite specialized, such as those serving any Flight Test Ground Station. In the recent past a large number of Ground Station systems were based in Digital’s VAX/VMS architecture. The computer industry then expanded very fast and by 1990 realtime PCM data processing systems totally dependent on hardware and software designed for IBM-PC compatible micro-computers were becoming available. A complete system replacement in a typical Ground Station can take from one to several years to become a reality. It depends on how complex the original system is, how complex the resulting system needs to be, how much resources are available to support the operation, how soon the organization needs it, etc. This paper intends to review the main concerns encountered during the replacement of a typical VAX/VMS-based by an Intel-Windows NT-based Ground Station. It covers the transition from original requirements to totally new requirements, from mini-computers to micro-computers, from DMA to high-speed LAN data transfers, while conserving some key architectural features. This 8-month development effort will expand EMBRAER’s capability in acquiring, processing and archiving PCM data in the next few years at a lower cost, while preserving compatibility with old legacy flight test data.

Afin d'etudier la proteine abp1, une proteine de liaison d'auxine, des outils ont ete reunis sur un meme materiel, le tabac. 9 anticorps monoclonaux distincts diriges contre la proteine abp1 de tabac (nt-abp1) ont ete obtenus. La caracterisation de l'interaction de ces anticorps avec la proteine nt-abp1 a montre que ces anticorps ont une affinite elevee pour la proteine et reconnaissent des epitopes discontinus, dependants de la conformation de la proteine. De plus tous ces anticorps interferent avec une reponse precoce a l'auxine, demontrant l'implication de l'abp1 dans les premieres etapes de perception de l'auxine au niveau de la membrane plasmique. Dans le but de determiner l'importance de la region c-terminale pour la fonction de la proteine au niveau de la membrane plasmique, nous avons entrepris une approche de mutagenese dirigee des residus conserves de cette region. L'etude de l'interaction des proteines mutees avec les anticorps suggere que les mutations ponctuelles modifient le repliement de la proteine, alterant son activite au niveau de la membrane plasmique. Les anticorps anti-nt-abp1 ont ete utilises pour etudier la fonction de la proteine nt-abp1 in vivo. Nous avons developpe une strategie fondee sur l'utilisation de ces anticorps, dite d'immunisation cellulaire. Le but est d'exprimer dans la cellule des scfv (single chain fragment variable) afin d'agir directement sur la proteine. Les scfv correspondant a 4 anticorps distincts ont ete obtenus. L'etude de leur interaction avec la proteine nt-abp1 a montre que les scfv ont conserve les memes caracteristiques que les anticorps initiaux. Dans le but de perturber la proteine nt-abp1, localisee dans le reticulum endoplasmique et au niveau de la membrane plasmique, les scfv ont ete modifies afin de cibler leur expression au niveau de ces deux sites. Les resultats preliminaires obtenus dans les cellules de tabac en culture suggerent qu'il existe un lien entre la proteine abp1 et la division cellulaire.

O objetivo geral da pesquisa foi associar os polimorfismos do gene HLA-G (região 3\' NT) com a coinfecção HIV/HCV e com os grupos (HIV, HCV e controles saudáveis). Trata-se de um estudo transversal, comparativo, descritivo. Participaram do estudo, 560 indivíduos, sendo 156 controles saudáveis, 102 coinfetados HIV/HCV, 186 infectados pelo HIV e 116 por HCV. Para a identificação dos polimorfismos, o DNA genômico foi extraído do sangue total e a genotipagem feita por PCR e visualizada em gel de poliacrilamida a 7%, no qual o polimorfismo de 14pb foi identificado, e por sequenciamento os outros sete SNPs. Os resultados sociodemográficos apontam que a amostra na sua grande maioria foi composta por indivíduos adultos e do sexo masculino. No que diz respeito à cor da pele, na comparação entre os grupos HCV e HIV/HCV, observou-se um maior número de coinfectados apresentando a cor preta e parda do que nos monoinfectados (P=0,0001). Com relação à categoria de exposição para aquisição do HIV, na comparação entre os grupos HIV e HIV/HCV, observou-se diferença significante na transmissão por via heterossexual, sendo sua frequência maior no grupo HIV (P=0,0000). No caso da comparação entre os grupos HCV e HIV/HCV, observou-se também diferença na transmissão heterossexual, sendo sua frequência significantemente maior no grupo HIV/HCV (P=0,0001). Quanto aos achados relacionados ao genótipo do HCV, na comparação entre os grupos HCV e HIV/HCV, o genótipo 1a apresentou frequência maior nos coinfectados (P=0,0001). No que diz respeito à carga viral do HIV, na comparação entre os grupos HIV e HIV/HCV, o grupo da monoinfecção apresentou maior carga viral do que o grupo da coinfecção (P=0,0350). Com relação ao grau de fibrose hepática, na comparação entre os grupos HCV e HIV/HCV, o grupo da coinfecção tem mais fibrose leve do que o grupo da monoinfecção (P=0,0009). Quanto aos polimorfismos genéticos da região 3\' NT do HLA-G, foi encontrado que o genótipo de heterozigose Del/Ins de 14 pb apresentou diferença significante nos indivíduos coinfectados pelo HIV/HCV (P=0,0216) quando comparados com o grupo controle. Em relação ao SNP +3003, a comparação dos grupos HCV e controle saudável mostrou que alelo +3003T apresentou uma frequência significantemente maior no grupo HCV (P=0,0147); o genótipo +3003C/T apresentou uma frequência maior no grupo controle (P=0,0095); o genótipo +3003T/T estava maior no grupo HCV (P=0,0095). A comparação entre os grupos HIV e HCV mostrou que a frequência do alelo +3003C estava maior no grupo HIV (P=0,0463); e o genótipo +3003T/T apresentou uma frequência maior no grupo HCV (P=0,0494). A frequência do genótipo +3187A/A estava maior no grupo HIV/HCV em comparação ao HIV (P=0,0193); e do +3187A/G estava maior no grupo HIV (P=0,0187). O genótipo +3196C/G apresentou frequência significamente maior no grupo HIV do que no controle saudável (P=0,0213). A UTR-10, na comparação entre os grupos HIV e controle, mostrou frequência maior no grupo HIV (P=0,0044); quando comparados os grupos HIV/HCV e HIV, frequência foi maior no grupo HIV (P=0,0300) e na comparação entre os grupos HIV e HCV, sua frequência também foi maior no grupo HIV (P=0,0140). A UTR-4, na comparação dos grupos HCV e controle saudável, revelou uma frequência maior no grupo controle (P=0,0147). A UTR-9, na comparação dos grupos HIV/HCV e HIV, mostrou frequência maior no grupo HIV/HCV (P=0,0460). Em relação aos dados clínicos, a presença do alelo T na posição +3035 foi significantemente associada à maior carga viral do HCV, acima de 400.000 cópias/mL (P=0,0244). Em relação aos tipos de genótipos do HCV, a presença do alelo +3027C foi associada ao subtipo 1a do HCV (P=0,0109). Adicionalmente, a presença do genótipo C/C na posição +3027 também foi significantemente associada com o subtipo 1a do HCV (P=0,0015). Ainda, o alelo A do SNP +3187 foi significantemente associado com os outros genótipos do HCV, excluindo o 1a (P=0,0369). Embora não esteja totalmente esclarecida a função do gene HLA-G, estudos têm sido desenvolvidos para melhor elucidar sua função nos contextos fisiológicos, como gestação, e patológicos, como tumores, transplantes, doenças inflamatórias e infecciosas. Tais estudos procuram ampliar o conhecimento sobre o sistema imunológico e contribuem para o desenvolvimento de novas estratégias diagnósticas e terapêuticas. Os resultados do presente estudo contribuem para a ampliação do conhecimento sobre os polimorfismos da região 3\' NT do gene HLA-G, na coinfecção HIV/HCV. Como também, na melhoria da assistência de enfermagem que deve buscar reduzir a morbimortalidade pela referida patologia. Porém, ainda há um longo percurso a ser percorrido na compreensão dos fatores imunogenéticos envolvidos na coinfecção pelo HIV/HCVThe general objective of the research was to associate the polymorphism of the gene HLA-G (region 3\' NT) with the co-infection HIV/HCV and with the groups (HIV, HCV and healthy control). It is a cross-sectional, comparative, descriptive study. 560 individuals participated of the study, being 156 healthy control individuals, 102 co- infected HIV/HCV, 186 infected by HIV and 116 by HCV. For identifying the polymorphisms, the genomic DNA was extracted from the total blood and the genotyping was made by PCR and visualized in gel of polyacrylamide at 7%, in which the polymorphism of 14pb was identified, and by sequencing the other seven SNPs. The social demographic results point that the most of the sample was composed by male adult individuals. Regarding the color of the skin, in the comparison between the groups HCV and HIV/HCV, a bigger number of co-infected with black skin and brown-skinned was observed than in the mono infected (P=0,0001). Regarding to the category of exposition for acquisition of the HIV, in the comparison between the groups HIV and HIV/HCV, a significant difference was observed in the transmission through heterosexual exposition, being its frequency bigger in the group HIV (P=0,0000). In the case of the comparison between the groups HCV and HIV/HCV, the difference in the heterosexual transmission was also observed, being its frequency significantly higher in the group HIV/HCV (P=0,0001). About the finding related to the genotype of the HCV, in the comparison between the groups HCV and HIV/HCV, the genotype 1a presented higher frequency in the co- infected (P=0,0001). Regarding to the viral load of the HIV, in the comparison between the groups HIV and HIV/HCV, the group of the mono infection presented bigger viral load that the group of the co-infection (P=0,0350). Regarding to the level of hepatic fibrosis, in the comparison between the groups HCV and HIV/HCV, the group of co-infection has a lighter fibrosis that the group of the mono infection (P=0,0009). Regarding to the genetic polymorphisms of the region 3\' NT of the HLA-G, it was found that the genotype of heterozygosis Del/Ins of 14 pb, presented significant difference in the individuals co-infected by the HIV/HCV (P=0,0216) when compared with the control group. About the SNP +3003, the comparison of the groups HCV and healthy control, it was showed that the allele +3003T presented a significant higher frequency in the group HCV (P=0,0147); the genotype +3003C/T presented a higher frequency in the control group (P=0,0095); the genotype +3003T/T was bigger in the group HCV (P=0,0095). The comparison between the groups HIV and HCV showed that the frequency of the allele +3003C was bigger in the group HIV (P=0,0463); and the genotype +3003T/T presented a bigger frequency in the group (P=0,0494). The frequency of the genotype +3187A/A was bigger in the group HIV/HCV in comparison to the HIV (P=0,0193); and of the +3187A/G was bigger in the group HIV (P=0,0187). The genotype +3196C/G presented frequency significantly bigger in the group HIV than in the healthy control (P=0,0213). The UTR-10, in comparison between the groups HIV and control, showed bigger frequency in the group HIV (P=0,0044); when compared the groups HIV/HCV and HIV, frequency was bigger in the group HIV (P=0,0300) and in the comparison between the groups HIV and HCV, its frequency was also bigger in the group (P=0,0140). The UTR-4, in the comparison of the groups HCV and healthy control, revealed a bigger frequency in the control group (P=0,0147). The UTR-9, in comparison of the groups HIV/HCV and HIV, showed bigger frequency in the group HIV/HCV (P=0,0460). Regarding to the clinical data, the presence of the allele T in the position +3035, was significantly associated to bigger viral load of the HCV, above 400.000 copies /mL (P=0,0244). About the types of genotypes of the HCV, the presence of the allele +3027C was associated with the subtype 1a of the HCV (P=0,0109). Additionally, the presence of the genotype C/C in the position +3027 was also significantly associated with the subtype 1a of the HCV (P=0,0015). Still, the allele A of the SNP +3187 was significantly associated with the other genotypes of the HCV, excluding the 1a (P=0,0369). Although the function of the gene HLA-G, is not totally clarified, studies have been developed for better elucidate its function in the physiological contexts, like gestation, and pathological, such as tumours, transplants, infectious and inflammatory diseases. These studies aim to extend the knowledge about the immunological system and contribute for the development of new diagnostic and therapeutic strategies. The results of this study contribute for enhancement of the knowledge about the polymorphisms of the region 3\' NT of the gene HLA-G, in the co-infection HIV/HCV. As well as, in the improvement of the assistance of nursing that must seek reducing the morbid mortality by the pathology referred. However, there is still a long path to be followed in the comprehension of the immunogenic factors involved in the co-infection by the HIV/HCV

Full textAbstract:
Le type d'humus que l'on peut observer sous foret resulte d'interactions nombreuses et complexes entre les conditions abiotiques (facteurs physiques et chimiques de l'environnement) et les facteurs biotiques (communautes vegetales, animales, fongiques et microbiennes). C'est en milieu montagnard (massif de la chartreuse), ou ces interactions sont mal connues, que nous avons etudies le determinisme et le fonctionnement des differents types d'humus a deux echelles de perception. A petite echelle (approche stationnelle), on observe un lien etroit entre la morphologie des humus et la repartition des especes vegetales. Cette morphologie est surtout dependante des facteurs physiques de l'environnement (bilan hydrique, aeration). A grande echelle, une etude du fonctionnement de quatre humus (deux mulls, un mor, et un tangel), correspondant a deux niveaux d'activite biologique tranches et a deux contextes edaphiques chimiques varies (acide et neutre), a ete menee. Le microclimat au sol des deux mulls differe de ceux du mor et du tangel par une xericite moindre, ceci etant essentiellement du a la vegetation herbacee tres differente. L'humidite edaphique est egalement plus elevee dans les deux humus de type mull (notamment grace a des apports par ruissellement). L'activite biologique (essentiellement lombricienne), tres superieure dans les deux mull, temoigne des conditions physiques favorables dans les deux mull, la xericite dans le tangel, et l'anoxie dans le mor, limitant cette activite.
